Technical Field

The invention relates to the technical field of plasma treatment, in particular to a shock control method of a dry type slurry melting machine.

Background

Existing blood products are stored in a freezer refrigerator, for example, plasma is stored frozen in a-30 ℃ refrigerator. Prior to infusion, thawing is required. The thawing device for plasma is generally called a thawing machine. The user has no specific standard for determining whether the plasma is completely thawed, and the determination is generally made by visually checking whether there are ice crystals in the blood bag or by sensing the surface temperature by hand. This method is inaccurate and time consuming.

There is also a plasma melter that monitors the internal plasma temperature by a simulated bag technique. The user needs to freeze the simulation bag and normal plasma together for melting, and a detector arranged in the simulation bag is connected with a probe of a thawing area of the thawing machine during melting, so that the internal temperature of the simulation bag can be monitored, the temperature of other blood bags melted in the same batch can be judged, and the melting state can be judged. However, the mode of the simulation bag is complicated to operate, and market research shows that users are often troubled to use during actual use, and the significance of monitoring the temperature is lost.

In addition, in order to heat the blood products in the blood bag uniformly, the existing water bath or air bath type slurry melting machine is generally provided with a shaking or shaking device, and shaking treatment is carried out in the melting process. However, in the air bath type plasma melting or other anhydrous plasma melting modes, there is a risk of blood bag abrasion in the shaking/shaking process due to no water buffer.

The invention discloses a vibration control method of a dry type slurry melting machine, which mainly aims to avoid the situation of bag breaking in the melting process of a blood bag by controlling the starting and stopping of a vibration module and the vibration frequency.

The dry slurry melting machine of the embodiment takes an air bath type as an example, and mainly comprises a vibration module, a heating module, a fan module and the like.

The vibration module is used for driving the blood bag to vibrate and accelerating the plasma melting efficiency.

The blood bag can be placed on the tray, vibrates the module and vibrates the tray, and then reaches the effect of vibrating the blood bag.

The heating module can adopt a heating wire, and the fan module is used for conveying heat generated by the heating module into the slurry melting space and realizing slurry melting through hot gas.

An air inlet channel and an air return channel are arranged in the slurry melting machine, so that the circulating circulation of hot air is realized.

The oscillation control method mainly refers to a control method of an oscillation module, and particularly relates to control of the oscillation module according to an oscillation mode and an oscillation frequency of a slurry melting process.

Different vibration modes and vibration frequency, effect mainly used avoid the blood bag to take place the damage in melting thick liquid in-process, do not influence simultaneously and melt thick liquid efficiency, help improving to a certain extent on the contrary and melt thick liquid efficiency.

The reason why the blood bag is broken in the plasma melting process is that the plasma in the blood bag is still in a completely frozen state or a state close to the completely frozen state in the initial stage of melting, the blood bag is hard, and if the blood bag is vibrated, the blood bag is easy to shake and rub on the tray to break the blood bag.

The main effect that the vibration module vibrates the blood bag is used for accelerating the contact of solid blood and liquid blood in the blood bag, and the solid blood rocks in the liquid blood through vibrating, improves and melts thick liquid efficiency and homogeneity.

Therefore, in the initial stage of plasma melting, because the blood bag has no liquid blood, the oscillation does not play a role in accelerating plasma melting in the stage, and the risk of bag breaking is generated.

In order to avoid the blood bag breaking at the initial stage of plasma melting, the oscillation module may not operate or oscillate at a low frequency at the initial stage of plasma melting.

And in the middle stage of plasma melting, the solid blood in the blood bag is continuously melted, the liquid blood is continuously increased, and the vibration module works at the moment to play a role in accelerating plasma melting.

However, the shaking module is also inconvenient to shake too fast at this stage, and if the shaking is too fast, the ice block may continuously touch the friction blood bag, and the risk of bag breaking is also generated.

And in the later stage of plasma melting, liquid blood in the blood bag is more than solid blood, and the oscillation module can work at high frequency at the moment to further accelerate plasma melting.

So this application will vibrate the oscillation frequency of module and combine with melting thick liquid stage, according to melting the reasonable control oscillation frequency that comes of going on in thick liquid stage, can enough avoid broken bag, can guarantee again to melt thick liquid efficiency.

For the specific control of the oscillation module, two control modes are provided in the application, the first is an oscillation control method based on time, and the second is an oscillation control method based on temperature, which is described in detail below.

Embodiment a method for oscillation control based on time

The running of the oscillation module is controlled through the preset time, the plasma melting effect is improved, and the blood bag is prevented from being broken in the plasma melting process.

Specifically, the system presets N operation time nodes, and the thick liquid procedure of melting moves between the time node of difference, also along with the continuous of thick liquid process of melting, vibrates the module and is in different vibration modes, and the vibration frequency under different vibration modes is different, and the vibration frequency is relevant with the melting degree of plasma in the blood bag.

The melting degree of the plasma can be judged according to the proportion of the solid blood and the liquid blood in the blood bag, and if the liquid blood is too much, the oscillation frequency can be faster.

The time for entering each slurry melting stage is preset by the system or set by the user, the structure is simple, the cost is low, the bag breaking can be effectively avoided, and the slurry melting effect is ensured.

The oscillation control method can be used for dry-type slurry melting machines in any structural form, the applied slurry melting machines do not need to be structurally changed, only the combination control of the time node and the oscillation module is added in a control program, and the applicability is strong.

The time nodes can be arranged in a plurality of numbers, two adjacent time nodes correspond to one oscillation mode, namely one oscillation frequency, and the oscillation frequencies in different adjacent time node periods can be kept unchanged or changed according to a certain rule in different slurry melting stages.

The system can set different time node numbers and time node intervals for different volumes of blood bags.

That is, the system is set with multiple plasma-melting procedures, each for melting a range of volumes of blood bags.

The difference of each slurry melting program is the difference of the number of time nodes and the interval of the time nodes and the difference of the oscillation frequency under the corresponding interval of the time nodes.

For example, in a plasma-melting procedure for melting a large-volume blood bag, more time nodes can be set; in a plasma-melting procedure for melting a small volume blood bag, the time node may be set a little less.

The time node can be set by the user before slurry melting, and can also adopt default parameters of the system.

The application provides a specific embodiment, the system presets operation time nodes T1, T2 and T3, wherein T1 is more than T2 is more than T3;

the plasma melting early stage is between the start of the plasma melting program and the time T1, the heating module and the fan module are always operated to keep the temperature in the box for plasma melting, and the oscillation module is closed to avoid bag breaking caused by blood bag oscillation;

the plasma melting program is operated between time T1 and time T2 to be a plasma melting middle stage, enough melted liquid blood is arranged at the bottom of the blood bag, the solid blood in the blood bag starts to float upwards, the oscillation acceleration mode is started by the oscillation module at the moment, the oscillation frequency is gradually increased, the plasma melting efficiency is accelerated, and the temperature of the liquid blood is ensured to be uniform;

the plasma melting program is operated between the time T2 and the time T3, namely the later stage of plasma melting, a small amount of floating solid blood can exist at four corners in the blood bag, the oscillation module is in an oscillation maintaining mode, and the oscillation module oscillates continuously at the natural frequency, so that the floating solid blood is guaranteed to be completely melted;

when the plasma melting program runs to the time T3, the oscillation module is closed, and the long-time oscillation running also has the risk of bag breaking, and prompts a user to take out the blood bag after the melting is finished.

In some embodiments of the application, the operation of the oscillation module is automatically started, stopped and changed according to the operation time of the slurry melting program, so that one-key automatic control is realized.

Namely, when the melting pulp enters the middle stage, the oscillation module automatically enters an oscillation acceleration mode;

when the slurry is melted and enters the later stage, the oscillation module automatically enters an oscillation maintaining mode;

after the slurry is melted, the vibration module is automatically closed.

In some embodiments of the present application, the oscillation module continuously oscillates at the oscillation frequency at the end of the oscillation accelerating mode in the oscillation maintaining mode.

Specifically, when the slurry melting operation time is at T1, the oscillation frequency is P1 (for example, 0.5 times/s), the oscillation frequency gradually increases to P2 (for example, 2 times/s) as the operation time increases to T2, and then the slurry melting later stage is entered, the oscillation module operates to T3 at the oscillation frequency P2, and the oscillation ends.

In other embodiments, the oscillation frequency of the oscillation module in the oscillation maintaining mode may be greater than the oscillation frequency at the end of the oscillation accelerating mode.

In some embodiments of the present application, after the oscillation acceleration mode is finished, the system automatically stops the oscillation module or manually confirms that the oscillation module stops.

A stop button is arranged on a control panel of the slurry melting machine, and when manual confirmation is needed, the stop button is directly clicked.

In some embodiments of the present application, after the oscillation acceleration mode is finished, the oscillation module automatically stops after the continuous operation time Δ T (for example, 10 min), so as to ensure the completeness of the plasma melting and avoid the situation that solid blood still appears.

In some embodiments of the present application, after the oscillation acceleration mode is finished, additional oscillation time can be manually set according to the melting condition of plasma in the blood bag.

After the shock acceleration mode is ended, the user can further observe the blood melting condition in the blood bag, if still there is floating solid blood to appear, then can manually set up the oscillation time, make the module that shakes continue to shake for a period of time, then repeat above-mentioned user and confirm the process, melt until plasma completely.

In some embodiments of the present application, after the plasma-melting procedure is completed, the plasma-melting machine enters an internal heat-preserving procedure to keep the blood bag at a certain temperature (e.g., 37 ℃) so as to be taken out for direct use.

A display screen can be configured on an operation panel of the slurry melting machine, and a slurry melting stage, a vibration mode and a vibration frequency are displayed in a mode of combining pictures and texts, so that a user can conveniently know the current slurry melting progress.

Second embodiment oscillation control method based on temperature

Specifically, the temperature detection device detects the temperature of the blood bag or the tray for placing the blood bag.

According to the stage operation of the temperature control oscillation module, the plasma melting effect is improved, and the blood bag is prevented from being broken in the early stage of plasma melting.

N temperature values are preset by the system, when temperature data measured by the temperature detection device are between different temperature values, the oscillation modules for driving the blood bag to oscillate are in different oscillation modes, the oscillation frequencies in different oscillation modes are different, and the oscillation frequencies are related to the melting degree of plasma in the blood bag.

When solid blood in the blood bag is more, the temperature of the blood bag is lower, the cold quantity of the blood bag is transferred to the tray, and the temperature of the tray is lower.

Along with the continuous progress of plasma melting, the solid blood in the blood bag is gradually reduced, the liquid blood is gradually increased, and the temperature of the blood bag and the tray is gradually increased.

The temperature data measured by the temperature detection device gradually rises, which indicates that the solid blood in the blood bag gradually decreases and the liquid blood gradually increases.

By monitoring the temperature, the degree of melting in the blood bag can be roughly estimated, when the temperature is low, the oscillation frequency can be closed or the oscillation is carried out at a low frequency, and when the temperature is high, the oscillation module oscillates at a high frequency.

The temperature nodes can be arranged in a plurality of modes, an oscillation mode is corresponding to two adjacent temperature nodes, namely an oscillation frequency, and the oscillation frequency between two different adjacent temperature nodes can be kept unchanged or changed according to a certain rule in different slurry melting stages.

The system can set different temperature node numbers and temperature node spacings for different volumes of blood bags.

That is, the system is set with multiple plasma-melting procedures, each for melting a range of volumes of blood bags.

The different points of each slurry melting program are the difference between the number of temperature nodes and the distance between the temperature nodes and the difference between the oscillation frequencies of the corresponding temperature nodes.

For example, in a plasma melting procedure for melting a large volume blood bag, more temperature nodes can be set; in a plasma-melting procedure for melting a small volume blood bag, the temperature node may be set a little less.

The temperature node can be set by a user before slurry melting, and can also adopt default parameters of the system.

The application provides a specific embodiment, the system is preset with temperature values T1, T2 and T3, T1 is more than T2 is more than T3;

the time period from the start of the plasma melting program to the time when the temperature value of the blood bag or the tray reaches T1 is a plasma melting early stage, the heating module and the fan module are always operated to keep the temperature in the box for plasma melting, the vibration module is closed, and bag breakage caused by blood bag vibration is avoided;

the time period of the temperature value of the blood bag or the tray between T1 and T2 is the middle stage of plasma melting, enough melted liquid blood exists at the bottom of the blood bag, the solid blood in the blood bag starts floating upwards, the oscillation module starts an oscillation acceleration mode at the moment, the oscillation frequency is gradually increased, the plasma melting efficiency is accelerated, and the liquid blood is ensured to be uniform in temperature;

the time period of the temperature value of the blood bag or the tray between T2 and T3 is the later stage of plasma melting, a small amount of floating solid blood can exist at four corners in the blood bag, the oscillation module is in an oscillation maintaining mode, and the oscillation module oscillates continuously at a natural frequency to ensure that the floating solid blood is completely melted;

when the temperature value of blood bag or tray reached T3, vibrate the module and close, vibrate the operation for a long time and also have broken bag risk, the suggestion user takes out the blood bag that melts the completion.

In some embodiments of the present application, the operation of the oscillation module is automatically turned on and off and changed according to the temperature value measured by the temperature detection device, thereby realizing one-key automatic control.

Namely, when the melting pulp enters the middle stage, the oscillation module automatically enters an oscillation acceleration mode; when the slurry is melted and enters the later stage, the oscillation module automatically enters an oscillation maintaining mode; after the slurry is melted, the vibration module is automatically closed.

In some embodiments of the present application, the oscillation module continuously oscillates at the oscillation frequency at the end of the oscillation accelerating mode in the oscillation maintaining mode.

Specifically, the oscillation frequency of the oscillation module in the oscillation acceleration mode is increased from P1 (for example, 0.5 times/s) to P2 (for example, 2 times/s), and then the slurry melting later stage is entered, and the oscillation module is operated with the oscillation frequency P2 until the oscillation is finished.

In other embodiments, the oscillation frequency of the oscillation module in the oscillation maintaining mode may be greater than the oscillation frequency at the end of the oscillation accelerating mode.

In some embodiments of the present application, after the oscillation acceleration mode is finished, the system automatically stops the oscillation module or manually confirms that the oscillation module stops.

A stop button is arranged on a control panel of the slurry melting machine, and when manual confirmation is needed, the stop button is directly clicked.

In some embodiments of the present application, after the oscillation acceleration mode is finished, the oscillation module automatically stops after the continuous operation time Δ T (for example, 10 min), so as to ensure the completeness of the plasma melting and avoid the situation that solid blood still appears.

In some embodiments of the present application, after the oscillation acceleration mode is finished, additional oscillation time can be manually set according to the melting condition of plasma in the blood bag.

After the shock acceleration mode is ended, the user can further observe the blood melting condition in the blood bag, if still there is floating solid blood to appear, then can manually set up the oscillation time, make the module that shakes continue to shake for a period of time, then repeat above-mentioned user and confirm the process, melt until plasma completely.

In some embodiments of the present application, after the plasma-melting procedure is completed, the plasma-melting machine enters an internal heat-preserving procedure to keep the blood bag at a certain temperature (e.g., 37 ℃) so as to be taken out for direct use.

The operating panel of the slurry melting machine can be provided with a display screen, and the temperature, the slurry melting stage, the oscillation mode and the oscillation frequency of the blood bag or the tray are displayed in a mode of combining pictures and texts, so that a user can conveniently know the current slurry melting progress.

For temperature detection, this application presents two ways, the first is to detect the blood bag for utilizing infrared detection device, and the second is to detect the tray for utilizing temperature sensor, the following details.

Based on blood bag temperature detection

An infrared detection device (thermal imaging detection device) is arranged above the blood bag, obtains thermal imaging of the blood bag at a target time, obtains the temperature of each point in the blood bag through a processor, and takes the average value of the temperature of each point to be recorded as the temperature data of the blood bag.

When the oscillation module is started or stopped and the oscillation frequency is controlled, the temperature of each point in the blood bag is averaged.

T1 can take the value 0 ℃; t3 can take the value of 14-18 deg.C, T3 is considered as no ice crystal here, and the set value is obtained experimentally.

If the average temperature of each point in the blood bag is greater than T3 (T3 is regarded as the average temperature value at which the thawing process can be ended), and the temperature of each point is less than T1 (at this time, there may be ice floes in four corners of the blood bag), the oscillation module continues to operate in the oscillation maintaining mode.

If the average temperature of each point in the blood bag is greater than T3 and no individual point is less than T1, it indicates that the plasma has been completely melted and the shaking module is stopped.

If a plurality of blood bags are thawed at the same time, the blood bag with lower temperature is taken as the control execution standard.

For example, two blood bags are thawed at the same time, and if the temperature of one blood bag reaches the standard of entering the next thawing stage, and the temperature of the other blood bag does not reach the standard, the next thawing stage cannot be entered.

When utilizing infrared detection device, can show thermal imaging picture on the display screen and show, the aspect user does not open the door also can observe the blood bag condition of melting directly perceivedly.

Temperature detection based on tray

The temperature detection device adopts a temperature sensor which is arranged below the tray, the blood bag is placed above the tray, and the melting condition in the blood bag can be indirectly known by detecting the temperature of the tray.

The tray can be made of aluminum, aluminum alloy and the like, and the heat conduction efficiency is improved.

The temperature sensor may be disposed in plurality at the bottom of the tray, and an average value of the respective detection data is taken as the temperature data of the tray.

T1 may be set at 6-8 deg.C, T2 at 14-16 deg.C, T at 18-20 deg.C.

In the early stage of plasma melting, a blood bag is placed on a tray, a plasma melting program is started, the temperature of the bottom of the tray is firstly reduced to a certain temperature and then slowly increased, the temperature is changed, the detection accuracy is improved for placing a counting error, and after the plasma melting program is started for a period of time (for example, 2 min), a temperature sensor starts to detect the temperature of the tray.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
