Description

Technical Field

[0001] This utility model relates to the field of blood collection technology, specifically to a novel blood collection needle and blood collection tube kit. Background Technology

[0002] Blood collection needles and tubes are mainly used to collect venous blood samples from patients. Blood sample analysis provides doctors with a basis for clinical diagnosis and treatment. Blood collection is performed by medical staff who have received specialized training in blood collection techniques.

[0003] When medical staff collect blood, they use a blood collection needle to puncture the patient's blood vessel, and use the puncture needle to penetrate the rubber stopper of the blood collection tube. Using the negative pressure inside the blood collection tube, blood is drawn into the blood collection tube through the blood collection needle, rubber tubing, and puncture needle.

[0004] Because of the large amount of blood collected in a single session and the use of multiple blood collection tubes, the friction between the puncture needle and the rubber stopper gradually increases. This increases the risk of needle puncture injuries to medical staff when forcefully separating the needle and the blood collection tube. Furthermore, the inability to secure the puncture needle to the blood collection tube results in the needle detaching from the tube during blood collection. Therefore, there is an urgent need to design a new type of blood collection needle and blood collection tube kit to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a novel blood collection needle and blood collection tube kit to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] It includes a blood collection tube body and a blood collection needle body. A connecting component is provided on the top of the blood collection tube body, and a positioning component is provided on the top of the blood collection tube body.

[0026] like Figure 1-4 As shown in the figure, this utility model provides a novel blood collection needle and blood collection tube kit.

[0027] It includes a blood collection tube body 1 and a blood collection needle body 2. A connecting component 3 is provided on the top of the blood collection tube body 1, and a positioning component 4 is provided on the top of the blood collection tube body 1.

[0028] The connecting assembly 3 includes a test tube cap 5 bolted to the top of the blood collection tube body 1. A protrusion 6 is fixedly installed on the top of the test tube cap 5. A groove 7 is formed between the protrusion 6 and the test tube cap 5. A rubber stopper 8 is fixedly installed in the groove 7. An annular plate 9 is provided on the outer surface of the protrusion 6. A circular plate 10 is fixedly installed on the top of the annular plate 9. A puncture needle 11 is provided at the bottom of the circular plate 10. A first buckle 12 is fixedly installed on the top of the test tube cap 5. The annular plate 9 moves the puncture needle 11 through the circular plate 10, causing it to penetrate the rubber stopper 8. The first buckle 12 engages with a second buckle 17, limiting and fixing the test tube cap 5 and the annular plate 9. 1. Blood is drawn in by negative pressure and flows into the blood collection tube body 1 through the blood collection needle body 2, rubber tubing 20, and puncture needle 11. After blood collection is completed, following the above steps, the pressing plate 19 is squeezed to drive the second buckle 17 to squeeze, thereby releasing the limiting fixation of the tube cap 5 and the annular plate 9. The second buckle 17 squeezes the first spring 18, pulling the annular plate 9 out of the groove 14. The annular plate 9 releases its compression of the pressing plate 24. The third spring 25 squeezes the pressing plate 24 to move it. The pressing plate 24 squeezes the positioning plate 21 to reset it. The positioning plate 21 squeezes the second spring 23.

[0029] The connecting component 3 can shield the puncture needle 11 while limiting and fixing the test tube cap 5 and the ring plate 9, thereby preventing the puncture needle 11 from shaking off the test tube cap 5 during the blood collection process, thus increasing the safety of the blood collection needle and blood collection test tube set.

[0030] Reference Figure 3 In this embodiment, a connecting frame 13 is fixedly installed on the top of the test tube cap 5. A groove 14 is provided on the top of the connecting frame 13. A limiting frame 15 is slidably installed in the groove 14. The limiting frame 15 is fixedly connected to the annular plate 9. A limiting groove 16 is provided on one side of the limiting frame 15. A second buckle 17 is slidably installed in the limiting groove 16. A first spring 18 is fixedly installed between the second buckle 17 and the limiting frame 15. A pressing plate 19 is fixedly installed on one side of the second buckle 17.

[0031] The second buckle 17 can engage with the first buckle 12 to limit and fix the test tube cap 5 and the ring plate 9, thereby improving the stability of the blood collection needle and blood collection test tube set during use.

[0032] The length of the puncture needle 11 is less than the length of the annular plate 9, and the length of the puncture needle 11 is greater than the length of the rubber stopper 8.

[0033] A rubber hose 20 is fixedly connected to the top of the circular plate 10. The rubber hose 20 is connected to the puncture needle 11, and the blood collection needle body 2 is fixedly connected to one end of the rubber hose 20.

[0034] Reference Figure 4 In this embodiment, the positioning component 4 includes a positioning plate 21, a pulley 22, a second spring 23, a compression plate 24, and a third spring 25. The positioning plate 21 is slidably mounted on the top of the inner wall of the connecting frame 13. The pulley 22 is slidably mounted on one side of the positioning plate 21. The second spring 23 is fixedly mounted between the connecting frame 13 and the positioning plate 21. The blood collection needle body 2 is punctured into the patient's blood vessel. The ring plate 9 is held and inserted into the groove 14. The ring plate 9 compresses the compression plate 24, and the compression plate 24 compresses the third spring 25. The compression plate 24 releases its compression limit on the positioning plate 21. The second spring 23 compresses the positioning plate 21 to make it move. The positioning plate 21 drives the pulley 22 to move and guide the ring plate 9 to position.

[0035] The positioning component 4 can guide and limit the position of the annular plate 9, thereby facilitating medical staff to penetrate the rubber stopper 8 with the puncture needle 11, thus improving the efficiency of the blood collection needle and blood collection tube kit.

[0036] The extrusion plate 24 is set on the outer surface of the protrusion 6, and the third spring 25 is fixedly installed between the extrusion plate 24 and the test tube cap 5.

[0037] Working principle: First, the blood collection needle body 2 is punctured into the patient's blood vessel. The annular plate 9 is held and inserted into the groove 14. The annular plate 9 compresses the compression plate 24, which in turn compresses the third spring 25. The compression plate 24 releases its compression limit on the positioning plate 21. The second spring 23 compresses the positioning plate 21, causing it to move. The positioning plate 21 drives the pulley 22 to move and guide the annular plate 9. The annular plate 9, through the circular plate 10, drives the puncture needle 11 to move, causing it to penetrate the rubber stopper 8. The first latch 12 and the second latch 17 engage, limiting and fixing the test tube cap 5 and the annular plate 9. 1. Blood is drawn in by negative pressure and flows into the blood collection tube body 1 through the blood collection needle body 2, rubber tubing 20, and puncture needle 11. After blood collection is completed, following the above steps, the pressing plate 19 is squeezed to drive the second buckle 17 to squeeze, thereby releasing the limiting fixation of the tube cap 5 and the annular plate 9. The second buckle 17 squeezes the first spring 18, pulling the annular plate 9 out of the groove 14. The annular plate 9 releases its compression of the pressing plate 24. The third spring 25 squeezes the pressing plate 24 to move it. The pressing plate 24 squeezes the positioning plate 21 to reset it. The positioning plate 21 squeezes the second spring 23.
