Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a preferred embodiment of the present invention provides a medical infusion control method, including:

s1, obtaining the density value of the transfusion liquid in the medical data system;

a gravity sensor is arranged at the bottom of the infusion bottle to obtain an infusion weight value; it should be understood that the technical problem to be solved in step S2 of the present embodiment is how to obtain the weight of the remaining infusion solution, and the gravity sensor provided on the infusion bottle is only one implementation of the present embodiment, and the present embodiment may also obtain the weight value of the remaining infusion solution by other methods.

S3, acquiring the infusion speed value in real time by detecting the opening of a flow pusher on an infusion guide tube;

the infusion flow guide pipe is a device used for controlling the infusion flow rate on an infusion rod in the prior art, and the scheme realizes the acquisition of the infusion flow rate value by monitoring the opening of the infusion flow guide pipe; it should be understood that the technical problem to be solved in step S3 of the present embodiment is how to obtain an infusion speed value, and obtaining the infusion speed value by monitoring the opening of the infusion flow guide tube is only one implementation of the present embodiment, and the present embodiment may also obtain the infusion speed value by other methods.

S4, calculating the volume value of the residual transfusion liquid according to the density value and the residual weight value, and calculating the volume value and the transfusion speed value to obtain the residual transfusion time of the residual transfusion liquid;

according to the density formula: p is m/V1; wherein rho is a density value, m is a weight value, and V1 is a volume value; by knowing the density value ρ of the infusion liquid and the remaining weight value m of the infusion liquid, a volume value V1 of the remaining infusion liquid can be calculated (for the purpose of avoiding ambiguity with the following formula, the volume value is represented by V1);

according to the velocity-time formula: v2 ═ s/t; wherein v2 is the infusion speed value, s is the distance, and t is the time; because the original formula of the speed and the time is utilized, the formula is transformed in order to adapt to the technical scheme; it should be understood that s is described herein as the volume value V1 of the remaining infusate referenced in the density equation (since the total volume of remaining infusate is the "distance" that the catheter needs to travel); thus, based on the present embodiment, the velocity-time equation is transformed into: v2 ═ V1/t; wherein V2 is the infusion speed value, V1 is the volume value of the residual liquid, and t is the residual infusion time; in case the infusion rate value and the remaining fluid volume value are known, the remaining infusion time t can be calculated.

And S5, when the remaining transfusion time is less than a preset first time threshold value, sending out an alarm signal.

A time threshold value is set in a server in advance and is defined as a first time threshold value; in this embodiment, the first time threshold is 50 seconds; when the residual infusion time t calculated by the server is less than 50 seconds, the current infusion is considered to be about to end, and the infusion needle hole is pulled out by medical staff; it should be understood that the first time threshold may be arbitrarily set, and is not limited to only 50 seconds used in the present embodiment; the first time threshold is equivalent to only one time alert threshold function; it should be understood that reference herein to emitting an alarm signal includes emitting an audible alarm message and/or a light alarm message to alert a medical professional; the method also comprises the step of sending related warning information to the medical care workstation or the mobile terminal of the medical care worker through the server.

In another embodiment, the step S3 specifically includes:

s31, detecting and acquiring the opening of a flow pusher on the infusion guide tube;

and receiving the pre-acquired infusion density value and the residual infusion weight value through network transmission.

And S33, inputting the opening size of the flow pusher, the density value and the residual weight value into an established infusion speed model, and outputting to obtain an infusion speed value.

A transfusion speed model is established in advance, the opening size of the flow pusher, the transfusion density value and the residual weight value are used as independent variables, and the transfusion speed value is used as a dependent variable to be output; it should be understood that the infusion speed value is in principle only directly linked to the opening of the flow pusher; the larger the opening, the larger the flow rate; however, based on practical considerations, factors such as the liquid density and the remaining weight of the infusion solution may also be weak factors affecting the flow rate, and in order to make the detection data more accurate, in this embodiment, two factors affecting the liquid density and the remaining weight of the infusion solution are introduced for calculation, and an accurate infusion solution speed value is output.

In this embodiment, the method for establishing the infusion speed model specifically includes:

step 1: acquiring speed values of liquids with different densities when the liquids pass through a propeller at a specific opening value under the condition of the same volume; measuring for multiple times by changing the opening value of the impeller and the volume of the liquid to obtain a measurement data set;

step 2: copying the measurement data set into a training data set and a test data set;

and step 3: establishing a speed model, and inputting the training data set for training to obtain a training speed model;

and 4, step 4: when the training times of the training speed model reach a preset training time threshold or the training accuracy reaches a preset training accuracy threshold, inputting the test data set into the training speed model for testing to obtain a test speed model;

and 5: and when the test frequency of the test speed model reaches a preset test frequency threshold or the test accuracy reaches a preset test accuracy threshold, ending the model test to obtain the infusion speed model.

Setting another time threshold value in the server in advance, wherein the another time threshold value is defined as a second time threshold value; in this embodiment, the second time threshold is 30 seconds; when the residual infusion time t calculated by the server is less than 30 seconds, the current infusion can be considered to be immediately finished, but the medical staff does not reach the infusion site to pull out the infusion needle hole for the patient; in order to avoid the condition that air input or blood return and other hazards occur in the transfusion due to the fact that medical staff do not arrive at the site when the transfusion time is over, in order to gain more time for a patient, the server sends out a signal instruction for controlling the opening degree of the flow pusher, the opening degree of the flow pusher is reduced, the transfusion speed is reduced, and the residual transfusion time is longer; the action of controlling the opening degree of the flow pusher can be executed by a driving motor which is arranged on the flow pusher and used for controlling the opening degree of the flow pusher; the above-mentioned way of controlling the opening degree of the flow pusher is only one of the embodiments in the present application, and the technical problem to be actually solved by the technical scheme is how to control the slow down of the infusion speed. It should be understood that the second time threshold may be set arbitrarily, and is not limited to only 30 seconds used in the present embodiment; the second time threshold simply corresponds to a time control threshold function; in this embodiment, the second time threshold is smaller than the first time threshold.
