[0031] See also Figure 1-4 , 6-7, a device for processing needles after blood collection for immunological testing, comprising a box body 1, a plurality of through holes 9 connected to the inner cavity are opened at the upper end of the box body 1, and a collection box 2 matching the inner cavity is slidably connected to the bottom end of the inner wall of the box body 1, a pair of mutually symmetrical limit plates 4 are fixedly connected to the top end of the inner wall of the box body 1, a pair of limit plates 4 are respectively arranged on both sides of the plurality of through holes 9, and a pair of limit plates 4 are inclined at one end close to each other, a pair of mutually symmetrical movable blocks 8 are arranged between the pair of limit plates 4, and a pair of movable blocks 8 are arranged at one end away from each other as an inclined surface matching the limit plates 4, a servo motor 3 is installed on the box body 1, and a reciprocating screw rod 5 is fixedly connected to the output end of the servo motor 3, and the reciprocating screw rod 5 extends to the inner cavity of the box body 1, A mounting block 6 is provided on one side of the limit plate 4, and a screw sleeve 7 matching the reciprocating screw rod 5 is fixedly connected to the mounting block 6. The mounting block 6 is slidably connected to the limit plate 4, and a pair of mutually symmetrical movable grooves 12 are opened at one end of the mounting block 6 close to the limit plate 4. A pair of movable blocks 8 are slidably connected to a pair of movable grooves 12 respectively. A pair of movable blocks 8 are open at one end close to each other, and the inner walls of a pair of movable blocks 8 are slidably connected with a clamping block 11. The inner cavity of the movable block 8 is provided with a plurality of second springs 14, and the two ends of the second spring 14 are fixedly connected to the clamping block 11 and the inner wall of the movable block 8 respectively. The inner cavity of the movable groove 12 is provided with a first spring 13, and the two ends of the first spring 13 are fixedly connected to the movable block 8 and the inner wall of the movable groove 12 respectively.

[0032] HIV testing is usually performed by detecting HIV antigen antibodies or viral nucleic acid in blood samples, which may involve drawing a certain amount of blood samples. The needles, syringes and blood collection tubes used for drawing are all disposable items and must be centrally disposed of after use. In some cases, it may be necessary to separate the needles and syringes for better classification and treatment of medical waste. Currently, needles and syringes are mostly separated manually, which carries the risk of puncture and infection.

[0033] In this solution, medical staff can insert the needle tube that needs to be separated from the needle into the through hole 9. At this time, the needle will pass through the through hole 9 and come between the pair of clamping blocks 11. The needle tube is too thick to pass through the through hole 9 and will overlap the top of the box body 1. The pair of movable blocks 8 are located on the lower side between the pair of limit plates 4 in the normal state, and are acted upon by the first spring 13 in the pair of movable grooves 12. Please refer to Figure 6 , a pair of movable blocks 8 are always in a state of moving away from each other, and one end of a pair of movable blocks 8 moving away from each other is respectively in contact with a pair of limit plates 4. At this time, the medical staff starts the servo motor 3 to drive the reciprocating screw rod 5 to rotate, and the rotation of the reciprocating screw rod 5 can drive the screw sleeve 7 to move, and then drive the mounting block 6 to slide on the limit plate 4. The medical staff sets the number of rotations of the output end of the servo motor 3 so that the screw sleeve 7 can move from the lower side of the outer end of the reciprocating screw rod 5 to the upper side at one time, and then from the upper side back to the lower side. In the process of moving the mounting block 6, the mounting block 6 will drive the pair of movable blocks 8 to move. In the process of moving upward, the pair of movable blocks 8 are affected by the inclined surfaces of one end of the pair of limit plates 4 approaching each other, and will gradually move closer, thereby squeezing the pair of first springs 13 and driving the pair of clamping blocks 11 They move closer to each other and clamp the needle through a pair of clamping blocks 11. After the pair of clamping blocks 11 are brought together, they will squeeze the spring inside the movable block 8. Then when the mounting block 6 moves downward, it will drive the pair of movable blocks 8 to move downward, and then drive the pair of clamping blocks 11 to move downward. The pair of movable blocks 8 move away from each other under the elastic force of the first spring 13, and then drive the pair of movable blocks 8 to move away downward. Since the pair of clamping blocks 11 move a distance toward the inner cavity of the movable block 8, the pair of clamping blocks 11 will not disengage immediately, but will maintain the clamping of the needle and move downward, and then pull the needle downward to make the needle detach from the needle tube. As the movable block 8 continues to move downward, the pair of clamping blocks 11 will eventually disengage. At this time, the needle will detach from between the pair of clamping blocks 11 and fall into the collection box 2.

[0034] An anti-slip groove is formed on one end of a pair of clamping blocks 11 close to each other.

[0035] The setting of the anti-slip groove can enhance the friction between the clamping block 11 and the needle when the pair of clamping blocks 11 clamp the needle, and then when the clamping block 11 moves downward, it can help the clamping block 11 to better pull the needle out of the needle tube.

[0036] See also Figure 5 , multiple through holes 9 are arranged at equal intervals, and a support ring 10 is provided on the upper side of the multiple through holes 9, and the support ring 10 is fixedly connected to the top of the box body 1.

[0037] Medical staff can insert the needle tube into the support ring 10, and then make the needle pass through the through hole 9. The support ring 10 can support the needle tube to prevent the needle tube from tipping over. The setting of multiple through holes 9 and support rings 10 enables the device to simultaneously perform needle detachment processing on multiple needle tubes, which can effectively improve work efficiency.

[0038] Working principle:

[0039] During use, the medical staff inserts multiple needle tubes into multiple support rings 10 respectively, so that the needle extends through the through hole 9 to the inner cavity of the box 1 and comes between a pair of clamping blocks 11. Then the medical staff starts the servo motor 3 to drive the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 can drive the screw sleeve 7 to move, and then drive the mounting block 6 to slide on the limit plate 4. During the movement of the mounting block 6, the mounting block 6 will drive the pair of movable blocks 8 to move. During the upward movement of the pair of movable blocks 8, they will be affected by the inclined surfaces of the pair of limit plates 4 approaching each other at one end, and will gradually move closer, thereby squeezing the pair of first springs 13 and driving the pair of clamping blocks 11 to move closer to each other. The needle is clamped by the pair of clamping blocks 11. After the pair of clamping blocks 11 are close to each other, they will squeeze the spring inside the movable block 8. Then when the mounting block 6 moves downward , it will drive a pair of movable blocks 8 to move downward, and then drive a pair of clamping blocks 11 to move downward. The pair of movable blocks 8 move away from each other under the elastic force of the first spring 13, and then drive a pair of movable blocks 8 to move away downward. Since the pair of clamping blocks 11 move a distance toward the inner cavity of the movable block 8, the pair of clamping blocks 11 will not disengage immediately, but will maintain the clamping of the needle and move downward, and then pull the needle downward to make the needle separate from the needle tube. As the movable block 8 continues to move downward, the pair of clamping blocks 11 will eventually disengage. At this time, the needle will separate from between the pair of clamping blocks 11 and fall into the collection box 2. The medical staff will take the needle tubes with separated needles away from the support ring 10 for centralized processing. After a large number of needle tubes have been separated, the collection box 2 is taken out from the box body 1, and the needles in the collection box 2 are processed centrally.

Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
