Description

Technical Field

[0001] This utility model relates to the field of plasma testing technology, and more specifically, to a plasma testing sample collection device. Background Technology

[0002] Plasma testing sample collection devices, commonly known as plasma separators or plasma collection devices, are medical devices specifically designed to effectively separate plasma from other components in blood. Existing plasma testing sample collection devices require shaken after blood is dripped into the sampling port to ensure the blood is evenly distributed within the hollow fiber membrane at the bottom of the sampling port for subsequent separation. However, the blood collection tubes in existing devices are directly inserted into the collection unit and are prone to falling out during shaking, leading to contamination of the tube opening and hindering the normal collection process. Utility Model Content

[0003] The main objective of this invention is to provide a plasma testing sample collection device that can effectively solve the problem in the prior art where blood collection tubes are directly inserted into the collection device and easily fall off during shaking, causing contamination of the blood collection tube opening and affecting the normal operation of the collection work.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A plasma testing sample collection device includes a housing, wherein a sampling hole is provided on one side of the upper surface of the housing;

[0006] A hollow fiber membrane is disposed inside the shell;

[0007] The housing contains a blood collection tube, one end of which extends to the outside of the housing. A limiting component for limiting the position of the blood collection tube is provided on one side of the upper surface of the housing.

[0008] Preferably, the limiting component includes two slide grooves, both of which are formed on one side of the upper surface of the housing. A slider is slidably disposed in each of the two slide grooves. A connecting shaft is rotatably mounted on the upper surface of each of the two sliders. A rotating plate is fixedly mounted on the upper end of each of the two connecting shafts. A limiting rod is fixedly mounted on the lower surface of each of the two rotating plates.

[0009] Preferably, a slide rod is fixedly installed between the two inner walls of the two slide grooves, and the two sliders are slidably disposed on one side of the corresponding slide rod body, and a spring is sleeved on the other side of the two slide rod bodies.

[0010] Preferably, one of the rotating plates has a mounting groove on its upper surface, and a limiting plate is rotatably mounted between the two sides of the inner wall of the mounting groove via a rotating shaft.

[0011] Another type of rotating plate has a limiting groove on its upper surface, and the limiting plate and the limiting groove are interlocked.

[0012] Preferably, torsion springs are fitted on both sides of the rotating shaft, with one end of each torsion spring fixedly connected to the inner wall of the mounting groove, and the other end of each torsion spring fixedly connected to the limiting plate.

[0013] Preferably, the integrated blood collection tube is equipped with a limiting frame, and the two limiting rods are respectively inserted and cooperated with the corresponding limiting frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) After inserting the blood collection tube into the housing, the staff controls the movement of the slider to compress the spring. Then the staff rotates the rotating plate to rotate around the connecting shaft. After the limiting rod moves to one end of the blood collection tube, the staff releases the slider, the spring resets and pushes the slider, causing the rotating plate and the limiting rod to move along the groove direction, so that the limiting rod pushes the blood collection tube, thereby achieving the purpose of limiting the blood collection tube and preventing it from falling when the sampling device shakes.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-5 As shown, a plasma testing sample collection device includes a housing 1, and a sampling hole 2 is provided on one side of the upper surface of the housing 1;

[0024] A hollow fiber membrane 3 is disposed inside the shell 1;

[0025] A blood collection tube 4 is provided inside the housing 1. One end of the blood collection tube 4 extends to the outside of the housing 1. A limiting component 5 for limiting the blood collection tube 4 is provided on one side of the upper surface of the housing 1.

[0026] A compression block 15 is fixedly installed on the other side of the upper surface of the housing 1 via an elastic band 14.

[0027] The limiting component 5 includes two slide grooves 501, both of which are opened on one side of the upper surface of the housing 1. A slider 502 is slidably arranged in each of the two slide grooves 501. A connecting shaft 503 is rotatably mounted on the upper surface of each of the two sliders 502. A rotating plate 504 is fixedly mounted on the upper end of each of the two connecting shafts 503. A limiting rod 505 is fixedly mounted on the lower surface of each of the two rotating plates 504.

[0028] A slide rod 6 is fixedly installed between the two inner walls of the two slide grooves 501. Two sliders 502 are slidably mounted on one side of the corresponding slide rod 6. A spring 7 is sleeved on the other side of the slide rod 6.

[0029] The staff drips blood into sampling hole 2, then moves elastic band 14, causing squeezing block 15 to move to sampling hole 2. The staff then presses squeezing block 15, and under the air pressure generated by squeezing block 15 pushing into sampling hole 2, the blood enters hollow fiber membrane 3, which filters out the plasma in the blood. The plasma then enters the blood collection tube 4, making it convenient for the staff to collect blood. After the blood collection tube 4 is inserted into the housing 1, the staff controls slider 502 to move, causing spring 7 to be compressed. The staff then rotates rotating plate 504, making it rotate around connecting shaft 503. After limiting rod 505 moves to one end of blood collection tube 4, the staff releases slider 502, spring 7 returns to its original position and pushes slider 502, causing rotating plate 504 and limiting rod 505 to move along slide groove 501. This causes limiting rod 505 to push blood collection tube 4, thereby limiting blood collection tube 4 and preventing it from falling off when the sampling device shakes.

[0030] In another embodiment of the present invention, an installation groove 8 is provided on the upper surface of one of the rotating plates 504, and a limiting plate 10 is rotatably installed between the two sides of the inner wall of the installation groove 8 via a rotating shaft 9.

[0031] Another rotating plate 504 has a limiting groove 11 on its upper surface, and the limiting plate 10 and the limiting groove 11 are interlocked.

[0032] When the limiting rod 505 pushes and limits the blood collection tube 4, the staff rotates the limiting plate 10 so that it rotates along the rotating shaft 9, thereby making one end of it interlock with the limiting groove 11 to enhance the limiting effect.

[0033] In another embodiment of this utility model, torsion springs 12 are sleeved on both sides of the shaft body of the rotating shaft 9. One end of each torsion spring 12 is fixedly connected to the inner wall of the mounting groove 8, and the other end of each torsion spring 12 is fixedly connected to the limiting plate 10.

[0034] By setting a torsion spring 12, the limit plate 10 is prevented from shifting when shaking due to the elastic force of the torsion spring 12.

[0035] In another embodiment of this utility model, the blood collection tube 4 is integrated with a limiting frame 13, and two limiting rods 505 are respectively inserted and cooperated with the corresponding limiting frame 13.

[0036] By interlocking the limiting rod 505 with the limiting frame 13, the contact area between the limiting rod 505 and the blood collection tube 4 is increased, thereby enhancing the limiting effect.

[0037] The working principle of this plasma testing sample collection device:

[0038] In use, the operator drips blood into sampling hole 2, then moves elastic band 14 to move squeezing block 15 to sampling hole 2. The operator then presses squeezing block 15, and under the air pressure generated by squeezing block 15 pushing into sampling hole 2, the blood enters hollow fiber membrane 3, which filters out the plasma in the blood. The plasma then enters blood collection tube 4, making it convenient for the operator to collect blood. After inserting blood collection tube 4 into housing 1, the operator controls slider 502 to move, causing spring 7 to be compressed. The operator then rotates rotating plate 504, making it rotate around connecting shaft 503. After limiting rod 505 moves to one end of blood collection tube 4, the operator releases slider 502, spring 7 returns to its original position and pushes slider 502, causing rotating plate 504 and limiting rod 505 to move along slide groove 501. This causes limiting rod 505 to push blood collection tube 4, thereby limiting blood collection tube 4 and preventing it from falling off when the sampling device shakes.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
