Description

Technical Field

[0001] The utility model relates to the technical field of blood collection needle processing, and particularly relates to a device for pressing a spring into a blood collection needle. Background Art

[0002] A blood collection needle generally includes components such as an outer shell, a spring, and a needle core. The spring plays a role in pushing the needle core for puncture during the assembly process, while the outer shell provides structural support and protection to ensure the stable operation of the spring and the needle core. The development of blood collection needles has gone through multiple stages. From the initial willow leaf needle to the modern laser blood collection needle, each generation has its unique features and improvements. The first generation: Willow leaf needle: It is processed from a single piece of metal sheet, shaped like a willow leaf, with a relatively short tip length, simple packaging and is easily contaminated. The second generation: Plastic die-cast needle: It is formed by plastic die-casting, with the tip made of metals such as stainless steel, equipped with a plastic needle cap, more independent packaging. Removing the needle cap before use can prevent contamination. The needle is fine, and proper operation can reduce the pain of patients and it is inexpensive and disposable. The third generation: Mechanical blood collection needle: It uses a mechanical device, and the needle is punctured through an ejection device, accurate, fast and with low pain, basically solving the problems of strong pain and large wound of the first two generations of blood collection needles. The fourth generation: Laser blood collection needle: It uses laser energy to instantaneously melt tissue and penetrate the skin to form a bleeding point, with an extremely small wound and adjustable depth. There is no physical contact with the patient, which can prevent blood cross-contamination and is a relatively safe blood collection instrument.

[0003] In the prior art, blood collection needles are designed relatively precisely according to the usage scenarios and generally consist of 4 - 6 components. When assembling the spring and the outer shell of the blood collection needle, the current assembly is mainly completed semi-automatically or manually, and can only meet the assembly requirements of a single specification of the outer shell and spring of the blood collection needle, with a low scope of application.

[0004] Therefore, a device for pressing a spring into a blood collection needle is proposed. Content of the Utility Model

On one side of the support plate 1, there is a fixing plate 2. On one side of the fixing plate 2, there is an L-shaped plate 3. On one side of the fixing plate 2, there is a first slide rail 4. On the L-shaped plate 3, there is a lifting cylinder 6. At the bottom of the lifting cylinder 6, there is a first sliding seat 5, and the first sliding seat 5 is slidably arranged on the first slide rail 4. On one side of the first sliding seat 5, there is a pressing mechanism 7 for pressing and clamping one end of the spring into the internal buckle of the blood collection needle housing. On the top of the fixing frame 8, there is a feeding mechanism 9 for feeding the blood collection needle housing and the spring. On the fixing frame 8, there is a lifting mechanism 10 for height adjustment. On one side of the lifting mechanism 10, there is a placing plate 11. In this embodiment, during use, the height of the placing plate 11 is adjusted by the lifting mechanism 10 to adapt to the assembly of springs and blood collection needle housings of multiple specifications. The feeding mechanism 9 presses multiple assembled blood collection needle housings with springs against the inner wall of the placing plate 11 to limit their positions. Then, the pressing mechanism 7 presses multiple springs so that one end of the spring is clamped into the internal buckle of the blood collection needle housing, thus completing the assembly of the spring and the blood collection needle housing. The lifting cylinder 6 can drive the first sliding seat 5 to slide on the first slide rail 4, and the pressing mechanism 7 moves accordingly, which can adjust the height of the pressing mechanism 7 to improve the adaptability of the pressing mechanism 7 to the assembly of springs and blood collection needle housings of various lengths, thereby realizing the automatic pressing and assembly of springs and blood collection needle housings of multiple specifications, improving the processing efficiency, having simple operation, wide application range, and strong practicability.

[0031] In summary, during use, the height of the placing plate 11 is adjusted by the lifting mechanism 10 to adapt to the assembly of springs and blood collection needle housings of multiple specifications. The feeding mechanism 9 presses multiple assembled blood collection needle housings loaded with springs against the inner wall of the placing plate 11 to limit their positions. Then, the pressing mechanism 7 presses multiple groups of springs, so that one end of the spring is snapped into the internal buckle of the blood collection needle housing, thus completing the assembly of the spring and the blood collection needle housing. The lifting cylinder 6 can drive the first sliding seat 5 to slide on the first slide rail 4, and the pressing mechanism 7 moves accordingly, so that the height of the pressing mechanism 7 can be adjusted to improve the adaptability of the pressing mechanism 7 to the assembly of springs and blood collection needle housings of various lengths, thereby realizing the automatic pressing and assembly of springs and blood collection needle housings of multiple specifications, improving the processing efficiency, with simple operation, wide application range and strong practicability. By starting the first cylinder 1003, the second sliding seat 1005 is driven to slide horizontally on the two second slide rails 1004, and the arc-shaped plate 1006 moves accordingly, thereby adjusting the horizontal position of the arc-shaped plate 1006. When the arc-shaped plate 1006 moves forward, it will drive the fixed roller 1009 to roll on its surface, so that the sliding column 1008 slides upward in the mounting cylinder 1007, and the long plate 1010 and the placing plate 11 move upward accordingly, thereby adjusting the height of the placing plate 11. By starting the second cylinder 902, the third sliding seat 904 is driven to slide horizontally on the two third slide rails 903, and the backing plate 905 and the limiting plate 906 move accordingly. The limiting plate 906 presses the blood collection needle housing loaded with the spring against the inner wall of the placing plate 11 to limit its position. By starting the third cylinder 703, the connecting column 704, the fixed column 705, the buffer spring 706 and the pressing block 707 move downward, and the pressing block 707 presses the spring, so that one end of the spring is snapped into the internal buckle of the blood collection needle housing. With the cooperation of the fixed column 705 and the buffer spring 706, a buffering effect can be achieved, avoiding excessive pressing force on it and causing damage.
