Background

At present, the device for collecting and testing fingertip blood (such as HIV detection) on the market is usually an air bag type hose, a hollow air bag is arranged at a handheld end, and a thin hose with an embedded glass tube is arranged at a collecting end. When blood is collected, the glass tubule end is placed at the fingertip blood position, blood is collected by capillary action, and then the blood is moved to a test card box for sample adding (the card box is provided with 2 sample adding windows, wherein the front 1 is used for adding a blood sample, and the back 1 is used for adding a diluent).

However, under the condition that the operator contacts for the first time or does not guide the operation according to the specification, the operator usually holds the hollow air bag before sampling blood, then collects blood by using air pressure difference, and then drops the blood sample when the card box appoints a sample adding window, loosens the air bag, and air enters from the front end thin-opening glass tube due to the action of the air pressure difference, so that the blood sample is flushed to the end of the air bag, and can not be extruded or is difficult to extrude, and sampling failure is easily caused.

The whole sampling process is complex, and the devices (including blood sampling device, diluent containing device and card box) are many, so the operation is troublesome. In some existing products, a blood sampling device and a diluent containing device are integrated, and after blood sampling is finished, a blood sample is dripped and diluent is extruded at the same time, so that the sample and the diluent are mixed in advance, and a better detection effect cannot be obtained.

It should be noted that the samples may be different liquid samples, and the liquid samples in the following examples represent blood; the detection solution may be different reagents, and in the following examples, the detection solution is a diluent. The tubule sampler may be used in a variety of different sample tests, and the following examples are blood collection and AIDS testing.

The first embodiment is as follows:

as shown in fig. 1 to 7, the capillary tube sampler comprises a cap 10 and a bottle 20, wherein a partition wall 23 is arranged inside the bottle 20 to divide the space inside the bottle 20 into a first storage chamber 21 and a second storage chamber 22, a capillary tube 11 is arranged on the cap 10, and the capillary tube 11 is communicated with the inside of the bottle 20; the cover 10 is covered on the bottle body 20, the cover 10 moves relative to the bottle body 20, and the cover 10 is switched between a first state and a second state; when the cover 10 is in the first state, the capillary tube 11 is communicated with the second storage chamber 22, and the capillary tube 11 is isolated from the first storage chamber 21; when the cover 10 is in the second state, the capillary tube 11 is in communication with the first storage chamber 21.

The connection between the cap 10 and the bottle 20 is a flexible connection, and the positional relationship between the cap 10 and the bottle 20 is switched by the movement of the cap 10. The position relation of the cover body 10 and the bottle body 20 comprises two states, the capillary tube 11 is communicated with the second storage chamber 22 in the first state, the capillary tube 11 is isolated from the first storage chamber 21, the detection liquid in the first storage chamber 21 is in a blocking state at the moment, so the detection liquid cannot flow out, the cover body 10 is used for collecting a sample in the first state, the sample is absorbed in the capillary tube 11 through capillary action, the collection of the sample is completed, namely, the sample and the detection liquid are in a separated state, and the sample and the detection liquid can be effectively separated. When the sample needs to be dripped, the air in the second storage chamber 22 pushes the sample to be dripped by squeezing the bottle body 20, and the first storage chamber 21 is still in an isolated state, so that the detection liquid in the first storage chamber 21 cannot flow out. After the filling of the sample is completed, the cap 10 is moved so that the cap 10 is switched to the second state, the first storage chamber 21 is communicated with the capillary 11, and the detection liquid stored in the first storage chamber 21 can flow onto the capillary 11, and the detection liquid is squeezed out by continuously squeezing the bottle body 20. The sampling and the sample adding are completed, and the sample and the detection liquid can be separately added.

Since the air bag system is not adopted, the operator is not easy to have a first-come idea when collecting the sample, and the air bag system is considered as a pressing and sucking system to collect the sample, and further, blood is collected by pressing the bottle body 20 without or without completely reading the specification. Therefore, the sample is collected by the bottle 20 and the cover 10, and the sample is effectively prevented from being directly sucked into the second storage chamber 22 by the air pressure difference and being difficult to extrude, thereby avoiding the sampling failure.

The sample dripping of the thin tube sampler is controllable, the number of dripped drops can be controlled to achieve the purpose of controlling the amount, and the volume of each dripped drop is basically determined when the same liquid is extracted because the diameter of the capillary tube 11 is processed into a fixed specification. The excess sample can be dropped and discarded, and then the cover 10 is switched to the second state for dropping the detection liquid.

As shown in fig. 4 and 5, when the cover 10 is in the first state, the bottom of the cover 10 closes the opening of the first storage compartment 21; as shown in fig. 6 and 7, when the cover 10 is in the second state, there is a gap between the bottom of the cover 10 and the opening of the first storage chamber 21, and the capillary tube 11 is communicated with the second storage chamber 22. Here, the capillary tube 11 is not directly communicated with the second storage chamber 22, but the capillary tube 11 is communicated with the second storage chamber 22, and the first storage chamber 21 is communicated with the second storage chamber 22, so that the detection liquid in the first storage chamber 21 can flow through the second storage chamber 22 and then enter the capillary tube 11. The first storage room 21 is sealed by the bottom part without needing an additional process for packaging the first storage room 21 during processing.

As shown in fig. 2, specifically, the capillary tube 11 is disposed near the outer side of the cover 10, the capillary tube 11 has a first port 111 and a second port 112, the first port 111 is located at the top surface of the cover 10, and the second port 112 is located at the bottom surface of the cover 10. Wherein the second port 112 communicates with the second storage room 22.

Specifically, the bottom of the cover 10 is provided with a protruding blocking platform 12, and when the cover 10 is in the first state, the blocking platform 12 blocks the opening of the first storage chamber 21. The protruding structure of the plugging table 12 avoids the situation that the bottom of the cover body 10 is uneven, which results in poor plugging effect.

As shown in fig. 1 to 7, the partition wall 23 is annularly disposed at the center of the bottle 20, and the sealing platform 12 is correspondingly disposed in a circular truncated cone shape, and is located at the middle position of the bottom of the cover 10, and corresponds to the partition wall 23. The first storage chamber 21 is formed inside the partition wall 23, the second storage chamber 22 is formed outside the partition wall 23 and the sidewall of the bottle 20, and two concentric rings are formed in the top view direction, wherein the inner ring is the first storage chamber 21, and the outer ring is the second storage chamber 22. The truncated cone shape makes the diameter of the extended outer portion smaller and the diameter at the bottom of the lid body 10 larger, so that it is convenient to click into the partition wall 23. And the partition wall 23 is provided in the middle of the bottle body 20, so that the sealing table 12 is surely positioned above the partition wall 23 regardless of the rotation of the table, and the capillary 11 is always communicated with the second storage chamber 22. The side wall of the plugging table 12 is in interference fit with the partition wall 23, and a sealing effect is achieved in an extrusion mode.

As shown in fig. 1 to 3, a first engaging portion 13 is disposed on the cover 10, a second engaging portion 24 is disposed on the bottle 20, and the first engaging portion 13 and the second engaging portion 24 are movably engaged, so that the cover 10 is switched between a first state and a second state. The activity between the first mating portion 13 and the second mating portion 24 achieves a switching effect. Specifically, in the present embodiment, the first engaging portion 13 includes an internal thread, the second engaging portion 24 includes an external thread, and the cap 10 is threadedly engaged with the bottle 20. The up and down movement of the cover 10 is realized by screwing, and after the cover 10 moves upwards, the blocking table 12 is gradually separated from the partition wall 23, and the communication between the first storage room 21 and the second storage room 22 is completed. Moreover, due to the position relationship between the first storage chamber 21 and the second storage chamber 22, the capillary tube 11 is always ensured to be communicated with the second storage chamber 22 by adopting the rotation mode.

Wherein, the bottle body 20 is made of compressible and resilient material. For example, the bottle body 20 is made of plastic, the space of the second storage chamber 22 can be pressed by pressing the bottle body 20, air is extruded out, and the sample is extruded out, and the partition wall 23 forming the first storage chamber 21 is located in the middle of the bottle body 20, so that the sample is not pressed, and the detection liquid in the first storage chamber 21 cannot be pressed out.

The use method of the thin tube sampler comprises the following steps:

when a sample is sucked, the thin tube sampler is taken out, the cover body 10 is in a first state at the moment, the capillary tube 11 is communicated with the second storage chamber 22, and the capillary tube 11 is isolated from the first storage chamber 21, so that the capillary tube 11 is close to the liquid sample and sucks the sample through the capillary action;

when a sample is detected, by pressing the outer wall of the bottle body 20, the air in the second storage chamber 22 is squeezed, and the sample in the capillary tube 11 is squeezed by the air and drips out of the capillary tube 11;

after sample adding is finished, the cover body 10 is moved, the cover body 10 is switched to the second state, and the capillary tube 11 is communicated with the first storage chamber 21;

the bottle 20 is continuously pressed, and the detection liquid in the first storage chamber 21 flows out and flows out through the capillary tube 11.

By using the method, sample collection is realized, the sample is separated from the detection liquid, and the sample and the detection liquid are filled separately.

Example two:

as shown in fig. 8 to 10, the present embodiment is different from the first embodiment in that the first engaging portion 13 and the second engaging portion 24 respectively include a first protrusion 131 and a second protrusion 241, and the first protrusion 131 is engaged with the second protrusion 241. The first locking protrusion 131 and the second locking protrusion 241 are engaged with each other for mounting the cap 10 and the bottle 20, and the cap 10 and the bottle 20 are pulled upward to switch the position relationship, that is, the cap 10 is switched between the first state and the second state.

The first locking protrusion 131 and the second locking protrusion 241 are both closed-loop structures and respectively surround the cover 10 and the bottle body 20, and the number of the second locking protrusions 241 is two, so that the cover 10 can be effectively prevented from being pulled out of the bottle body 20 by excessive force when being pulled out upwards. The cap 10 and the bottle 20 are in interference fit.

The rest of the structure is the same as the first embodiment, and the description is not repeated here.

Example three:

as shown in fig. 9 and 10, the present embodiment is different from the second embodiment in that a flexible connecting band is provided between the cap 10 and the bottle 20. The cap body 10 and the bottle body 20 are connected by the connecting band, which can be integrally formed during processing, and avoid the loss of one of the cap body 10 and the bottle body 20. In addition, after use, the cap body 10 and the bottle body 20 can be connected by a connecting band, so that the cap body and the bottle body are not easy to separate, and the recovery is troublesome.

A protruding handle is further provided on the cover 10, which facilitates pulling up the cover 10.

The rest of the structure is the same as the embodiment, and the description is not repeated here.
