Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies, and in particular relates to a pulling detection device for a blood collection needle pusher. Background Art

[0002] Disposable blood collection needles are common medical supplies for collecting blood samples during medical examinations. Disposable blood collection needles mainly use the elasticity of the spring for rapid needle insertion and blood collection. Disposable blood collection needles are mainly composed of a needle core, a pusher, a spring, a shell, a cap and a twist cap. At present, in the production process of disposable blood collection needles, in order to reduce the labor intensity of the staff and improve the automation of production, special blood collection needle installation and testing equipment is often used to realize the automated production of disposable blood collection needles. The entire production process includes loading, testing, rejection of defective products, and unloading. Among them, the pull-out test of the pusher is very important. In order to avoid the situation where the needle core is not properly connected to the spring during the assembly process of the blood collection needle, the needle core cannot be retracted normally, which will cause the medical staff to scratch the patient or themselves during the blood collection process in the later stage, posing a safety hazard. Therefore, the pull-out test of the pusher is very important.

[0003] At present, the main principle of the pusher pull-out detection is to use air pressure equipment to clamp the needle core, then pull it up, and then use a laser detector to determine whether the needle core retracts normally. If the needle core retracts normally, continue to the next process. If there is an abnormality in the retraction of the needle core, it will be rejected.

[0004] During the above-mentioned pusher pull test, since the blood vessels of infants and young children are thinner and those of adults are thicker, the specifications of blood collection needles are different. In addition, for some blood collection needles with special requirements and made of special materials, it is often necessary to replace the corresponding clamps during testing, which will reduce the efficiency of the entire production line. In addition, blood collection needles of different specifications mixed together often need to be screened first, and the clamps need to be replaced multiple times according to different specifications, and tested in batches, which greatly reduces production efficiency.

[0005] In view of this, in order to improve the above technical problems, the present invention provides a pull detection device for a blood collection needle pusher. Summary of the invention

[0006] The technical problems to be solved by the present invention are as follows: In the existing blood collection needle pusher pull-out detection equipment, since the blood vessels of infants and young children are thinner and the blood vessels of adults are thicker, the specifications of blood collection needles are different.

In addition, for blood collection needles of different specifications mixed together, they often need to be screened first, and then the clamps need to be replaced multiple times according to different specifications, and they need to be tested in batches, which greatly reduces the production efficiency.

[0062] The second transmission unit 82 includes a pull rod 821, a second slider 822, a long rod 823, a short rod 824 and a motor 825. The pull rod 821 is located above the first slider 812 and connected to the first slider 812. The second slider 822 is located on the side of the pull rod 821 away from the first slider 812. The second slider 822 is fixedly connected to the pull rod 821. The second slider 822 is slidably connected to the first support plate 6. The long rod 823 is located on the second slider 822 and is rotatably connected to the second slider 822. The short rod 824 The short rod 824 is rotatably connected to the long rod 823 and the motor 825 is located at the end of the short rod 824 away from the long rod 823. The motor 825 shaft is fixedly connected to the end of the short rod 824 away from the long rod 823. The motor 825 is fixedly connected to the first support plate 6. The motor 825 is controlled by the device controller. When the contraction action of the pneumatic device 2 is completed, the controller controls the motor 825 to work. When the motor 825 shaft is not powered on, it can rotate when an external force is applied to it.

[0063] During the test, the output end of the air pressure device 2 extends, first driving the connecting plate 4 to move downward, the connecting plate 4 moving downward drives the multiple protection frames 5 to move downward, the protection frames 5 moving downward drives the No. 1 arc rod 811 to move downward, when the No. 1 arc rod 811 moves downward, the arc structure at the bottom is used to guide the needle core to enter between the two No. 1 arc rods 811, when the needle core enters between the two No. 1 arc rods 811, the two No. 1 arc rods 811 move away from each other until they adapt to the diameter of the needle core, and under the elastic action of the No. 1 spring 813, each group of two No. 1 arc rods 811 are moved away from each other. The arc rod 811 clamps the needle core, and then the output end of the air pressure device 2 contracts, driving the connecting plate 4 and the protection frame 5 to move upward, and the upward movement of the protection frame 5 drives the first arc rod 811 to move upward, and the first arc rod 811 pulls the needle core to make the needle core exposed from the blood collection needle shell, and then the controller controls the motor 825 to work, and the output shaft of the motor 825 rotates, driving the short rod 824 to rotate, and the short rod 824 rotates to pull one end of the long rod 823 to swing, and the other end of the long rod 823 is limited by the second slider 822, and drives the second slider 822 to do a straight The two motors 825 in each protection frame 5 move in opposite directions at the same time, so that when the two motors 825 in each protection frame 5 work, the two No. 2 sliders 822 are driven to move away from or approach each other. When the needle core is exposed from the blood collection needle shell, the motor 825 works to drive the two No. 2 sliders 822 to move away from each other again through the long rod 823 and the short rod 824, and the No. 1 spring 813 is squeezed again. The two No. 2 sliders 822 move away from each other through the pull rod 821, which makes the two No. 1 arc rods 811 The two arc-shaped rods 811 are separated from the needle core, and then the controller turns off the motor 825. If the pusher is installed properly, the needle core will shrink into the shell under the action of the spring force inside the blood collection needle, and then the spring 813 No. 1 restores its elastic deformation to drive the arc-shaped rod 811, the long rod 823, the short rod 824, the pull rod 821, the slider 822 and the motor 825 to reset. In the above process, the laser detector 3 is used to detect whether the needle core is reset normally. If it fails to reset normally, it will be removed in the subsequent process.

[0064] To ensure that when the pull rod 821 pulls the slider No. 1 812 to move, the slider No. 1 812 drives the arc rod No. 1 811 to move smoothly, a slider No. 3 11 is arranged above the slider No. 1 812, and the slider No. 3 11 is slidably connected to the support plate No. 1 6, and a connecting rod 12 is fixedly connected between the slider No. 3 11 and the slider No. 1 812, and the end of the pull rod 821 away from the slider No. 2 822 is fixedly connected to the middle part of the connecting rod 12, so that when the pull rod 821 pulls the connecting rod 12, the forces on both ends of the pull rod 821 are balanced, and the arc rod No. 1 811 is guaranteed to move smoothly under the limit of the slider No. 3 11.

[0065] The first auxiliary unit 91 includes a second arc rod 911, a fourth slider 912, a second spring 913 and a second fixing block 914. The second arc rod 911 is installed on the second support plate 7 through the fourth slider 912. The second arc rod 911 is in a "J" shape. The length of the second arc rod 911 is less than the length of the first arc rod 811, so that when the air pressure device 2 drives the first arc rod 811 and the second arc rod 911 to move downward, the first arc rod 811 first enters the blood collection needle housing to clamp the needle core, and the fourth slider 91 2 is located above the No. 2 arc rod 911 and is fixedly connected to the No. 2 arc rod 911, the No. 4 slider 912 is slidably connected to the No. 2 support plate 7, the No. 2 spring 913 is located on the side of the No. 4 slider 912 away from the motor 825, one end of the No. 2 spring 913 is fixedly connected to the No. 4 slider 912, a No. 2 fixing block 914 is provided at the end of the No. 2 spring 913 away from the No. 4 slider 912, the other end of the No. 2 spring 913 is fixedly connected to the No. 2 fixing block 914, and the No. 2 fixing block 914 is fixedly connected to the No. 2 support plate 7.

[0066] The second auxiliary unit 92 includes a third spring 921, a telescopic cylinder 922, an L-shaped telescopic rod 923, a third support plate 924, an electric telescopic rod 925, a jack 926 and a pressure sensor 927.

The telescopic cylinder 922 is sleeved on the outside of the third spring 921 and is fixedly connected to the fourth slider 912. One end of the L-shaped telescopic rod 923 is fixedly connected to the telescopic cylinder 922, and the other end is fixedly connected to the first support plate 6. The L-shaped telescopic rod 923 is composed of an L-shaped rod and a sliding tube, wherein one end of the L-shaped rod is fixedly connected to the telescopic cylinder 922. The second arc rod 911 is fixedly connected with the second arc rod 911, and a jack 926 is provided on the side of the second arc rod 911 away from the first arc rod 811. The other end of the slide tube is fixedly connected with the first support plate 6. The third support plate 924 is located on the side of the second arc rod 911 away from the first arc rod 811. The third support plate 924 is fixedly connected with the frame 1. The electric telescopic rod 925 is fixed on the third support plate 924. The output end of the electric telescopic rod 925 faces the second arc rod 911. A jack 926 is provided on the side of the second arc rod 911 away from the first arc rod 811. The pressure sensor 927 is installed in the jack 926, and the pressure sensor 927 is electrically connected to the electric telescopic rod 925.

[0067] During the detection, when the air pressure device 2 drives the protection frame 5 to move downward, the No. 1 arc rod 811 clamps the needle core, and at the same time, the two No. 2 arc rods 911 are respectively located outside the blood collection needle shell, and when the protection frame 5 moves downward, the arc structure at the bottom of the No. 2 arc rod 911 guides the blood collection needle shell to enter between the two No. 2 arc rods 911, and clamps the blood collection needle shell under the elastic force of the No. 2 spring 913, and then the controller controls the output end of the electric telescopic rod 925 to extend, and the output end of the electric telescopic rod 925 is extended and inserted into the jack 926 of the No. 2 arc rod 911, and squeezes the pressure sensor 927, and the pressure sensor After receiving the pressure, the device 927 feeds back the signal to the controller, and the controller controls the electric telescopic rod 925 to stop working. At this time, the electric telescopic rod 925 is inserted into the socket 926 of the second arc rod 911, and the electric telescopic rod 925 is fixed to the frame 1 through the third support plate 924, and the second arc rod 911 is limited. Then the controller controls the output end of the air pressure device 2 to contract, and drives the protection frame 5 to move up through the connecting plate 4. At this time, since the second arc rod 911 is fixed, the telescopic cylinder 922 is stretched, and the third spring 921 is stretched. At this time, the shell and the needle core move relative to each other, so that the needle core is exposed from the blood collection needle shell;

[0068] When the needle core leaks out of the blood collection needle housing, the controller controls the output end of the electric telescopic rod 925 to contract, so that the electric telescopic rod 925 is separated from the second arc rod 911, and then under the elastic force of the third spring 921 and the pulling force of the air pressure device 2, the second arc rod 911 moves up to the initial position and resets to prepare for the detection of the next group of blood collection needle pushers.

[0069] The telescopic cylinder 922 is in the maximum contraction state in the initial state, and the No. 3 spring 921 is in the relaxed state in the initial state, thereby ensuring that when the protection frame 5 drives the No. 2 arc rod 911 to move downward, the telescopic cylinder 922 will not move upward after receiving the opposite thrust from the blood collection needle housing, ensuring that the blood collection needle housing can smoothly enter between the two No. 2 arc rods 911.

The winding shaft 101 is fixedly connected to the rotating shaft of the motor through a coupling, and the motor is fixedly connected to the No. 1 support plate 6. One end of the alcohol cotton cloth 103 is wound around the unwinding shaft 102, and the other end is wound around the winding shaft 101. The alcohol cotton cloth 103 is in contact with a side of the No. 1 arc rod 811 away from the No. 1 spring 813, and the movement direction of the alcohol cotton cloth 103 is the unwinding shaft 102 → the inner side of the No. 1 arc rod 811 → the outer side of the No. 1 arc rod 811 → the winding shaft 101.

[0071] During the inspection, the controller controls the motor shaft to rotate, and the rotation of the motor shaft drives the winding shaft 101 to rotate. The winding shaft 101 rotates and pulls the alcohol cotton cloth 103 to pull out the alcohol cotton cloth 103 on the unwinding shaft 102. The alcohol cotton cloth 103 moves relative to the needle core, and can clean and disinfect the inner side of the No. 1 arc plate while cleaning and disinfecting the needle core. After each blood collection needle is inspected, the motor shaft drives the alcohol cotton cloth 103 to move continuously through the winding shaft 101, so that the woman can replace the alcohol cotton cloth 103 and prepare for the inspection of the next group of blood collection needle pushers to avoid impurities from contaminating the needle cores of multiple blood collection needles, thereby avoiding cross infection and providing sterile testing.
