Description

Technical Field

[0001] This utility model relates to the field of blood collection tube structure technology, and in particular to a blood collection tube for coagulation detection. Background Technology

[0002] In the transportation of blood collection tubes, existing tubes lack effective dust prevention measures. Due to the lack of proper insulation inside the tubes, dust and other particulate matter can easily enter; especially at the sealing gasket, dust and other impurities easily adhere. When the blood collection needle is inserted into the tube, these dust and other particulate matter are carried into the blood sample, thus contaminating the blood sample.

[0003] Traditional blood collection tubes mostly adopt an open, straight-insertion structure, which makes the insertion of the blood guide needle more convenient. However, this does not provide effective protection for the container and blood before and after blood collection, making it easy for dust and other impurities to enter the blood collection tube. Dust and other impurities may mix with the blood sample, affecting the accuracy of subsequent coagulation tests and interfering with the interpretation of test results. Therefore, this application designs a blood collection tube based on coagulation testing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a blood collection tube based on coagulation testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a blood collection tube for coagulation testing, comprising a storage tube, an installation sleeve at the upper end of the storage tube, a mating threaded plug at the upper end of the storage tube, a snap-fit ​​threaded groove at the inner bottom end of the installation sleeve for threaded connection with the mating threaded plug, and a guide limiting component inside the installation sleeve.

[0006] Preferably, the top of the mounting sleeve has an adhesive dust cover, and the side end of the adhesive dust cover has an annular groove.

[0007] Preferably, the guide limiting assembly consists of a connecting rotating sleeve and a limiting guide tube. The lower end of the connecting rotating sleeve is provided with a sealing abutment block. The limiting guide tube and the sealing abutment block are sealed by rotating the connecting rotating sleeve. The sealing abutment block abuts against and fits against the upper end of the inner wall of the storage blood vessel.

[0008] Preferably, the mounting sleeve is fitted with a limiting ring block for supporting the limiting guide tube.

[0009] Preferably, the top end of the limiting guide tube is provided with a sealing gasket.

[0010] Preferably, the blood vessel has a double-layer structure, with a vacuum cavity in the middle of the double-layer structure, and the outer layer of the blood vessel is made of impact-resistant plastic material.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the mounting sleeve and the adhesive dust cover can isolate the inside of the mounting sleeve, preventing dust and other particles from adhering to the sealing gasket during transportation, thus preventing dust and other particles from entering the blood collection tube when the blood collection needle is inserted, thereby achieving the function of dust protection for the blood collection tube. Furthermore, the cooperation between the sealing gasket and the guide limiting component facilitates the stable insertion of the blood collection needle while pressing and clamping it, thereby enabling the blood collection tube to achieve the function of negative pressure blood collection and isolation from the outside world. The tension of the sealing gasket can also be used to tighten and seal the hole formed by the puncture and withdrawal of the blood collection needle, thereby completing the isolation and sealing after sampling. Ultimately, this solves the problem that blood samples are easily contaminated before and after blood collection in existing blood collection tubes. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5This utility model discloses a blood collection tube for coagulation testing, comprising a storage tube 3, an mounting sleeve 2 at the upper end of the storage tube 3, and a mating threaded plug 10 at the upper end of the storage tube 3. The inner bottom end of the mounting sleeve 2 has a snap-fit ​​threaded groove 9 for threaded connection with the mating threaded plug 10. The mounting sleeve 2 contains a guide and limiting component. Through the design of the mounting sleeve 2, a blood guide can be better inserted to guide and store blood into the storage tube 3. The top of the mounting sleeve 2 has an adhesive dust cover 1, and the side end of the adhesive dust cover 1 has an annular opening... The groove, through the setting of the adhesive dust cover 1, can maintain a dust-free environment inside the installation sleeve 2 before the adhesive dust cover 1 is opened; the guide limiting component consists of the connecting rotating sleeve 4 and the limiting guide tube 5. The lower end of the connecting rotating sleeve 4 is provided with a sealing abutment block 7. The limiting guide tube 5 and the sealing abutment block 7 are sealed by the rotation of the connecting rotating sleeve 4. The sealing abutment block 7 abuts against and adheres to the upper end of the inner wall of the blood storage tube 3. Through the setting of the guide limiting component, the inserted blood guide needle can be limited to prevent the blood guide needle from rotating and shaking and affecting the blood collection operation of the blood guide needle.

[0021] In this utility model, a limiting ring block 8 for supporting the limiting guide tube 5 is snapped into the mounting sleeve 2. The limiting ring block 8 stabilizes the guiding tube 5 and prevents it from bending. A sealing gasket 6 is provided at the top of the limiting guide tube 5. The sealing gasket 6 tightens and seals the hole through which the blood collection needle is inserted after it is pulled out, thus achieving a seal after blood collection in the storage tube 3. The storage tube 3 has a double-layer structure with a vacuum chamber 11 in the middle. The outer layer of the storage tube 3 is made of impact-resistant plastic material. The double-layer structure of the storage tube 3 and the vacuum chamber 11 reduce the influence of ambient temperature on the blood sample and prevent damage to the blood collection tube if it falls outside.

[0022] Working principle: When using this utility model, first open the adhesive dust cover 1 and allow the blood collection needle to pierce through the sealing gasket 6. The adhesive dust cover 1 maintains a dust-free environment inside the installation sleeve 2 before it is opened. The middle section of the inserted blood collection needle is positioned at the guide and limit component. The guide and limit component limits the insertion of the blood collection needle, preventing it from rotating or shaking and affecting the blood collection process. Finally, after the blood sample is collected, the blood collection needle is removed. The sealing gasket 6 tightens and seals the hole through which the blood collection needle was inserted after the needle is removed, thus achieving a seal after blood collection in the storage tube 3. The double-layer structure of the storage tube 3 and the vacuum chamber 11 reduce the impact of ambient temperature on the blood sample and prevent damage if the blood collection tube falls outside. The use of the device is then complete.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
