[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Specific implementation examples are given below.

[0033] Please see Figures 1-4 This utility model provides a technical solution: a modular blood collection stent, including a stent body 1, with a plurality of placement chambers 2 inside the stent body 1, a placement rack 3 inside the placement chamber 2, a plurality of blood collection slots 4 at the bottom of the placement rack 3, and a fixing mechanism inside the placement rack 3 corresponding to the positions of the blood collection slots 4. The fixing mechanism includes a movable base column 5, a guide slide rod 6 passing through the bottom of the movable base column 5, a support spring 7 sleeved on the outside of the guide slide rod 6, movable rods 8 on both the front and rear sides of the movable base column 5, one end of the movable rod 8 connected to the movable base column 5, and the other end of the movable rod 8 connected to a clamping plate 9.

[0034] With the above solution: when in use, the suction tube is inserted into the suction tube placement groove 4, and the suction tube is pressed down to move the movable bottom column 5 down. Since the movable rod 8 is connected to the movable bottom column 5 and the clamping plate 9 respectively, the clamping plates 9 on both sides are driven to move towards each other along the support slide rod 10 under the action of the movable rod 8, so as to clamp and fix the lower part of the suction tube.

[0035] Furthermore, such as Figure 4 and Figure 6As shown, a limiting groove 11 is provided on the right side of the top of the clamping plate 9. A limiting mechanism is provided on the right side of the clamping plate 9. The limiting mechanism includes a limiting block 12. A U-shaped pull rod 13 is provided on the right side of the limiting block 12. A limiting spring 14 is sleeved on the lower part of the outside of the U-shaped pull rod 13. The limiting groove 11 is adapted to the limiting block 12. The limiting block 12 is fixedly connected to the U-shaped pull rod 13. The limiting block 12 is elastically connected to the placement rack 3 through the limiting spring 14.

[0036] With the above scheme: during use, when the clamping plates 9 on both sides move towards each other, they squeeze the limiting block 12 to the right. When the limiting groove 11 is aligned with the limiting block 12, the limiting block 12 is elastically connected to the placement rack 3 through the limiting spring 14. Under the elastic force of the limiting spring 14, the limiting block 12 is pushed into the limiting groove 11, thus completing the limiting and fixing of the clamping plate 9. When it is necessary to release the blood collection tube, the U-shaped pull rod 13 is pulled to move the limiting block 12 to the right and away from the limiting groove. Since the movable bottom column 5 is elastically connected to the placement rack 3 through the support spring 7, the movable bottom column 5 is pushed upward under the action of the support spring 7, thereby causing the clamping plates 9 on both sides to move backward under the action of the movable rod 8, thus releasing the blood collection tube.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, guide sliders 15 are provided on both the left and right sides of the placement rack 3. The guide sliders 15 are "L" shaped. Guide grooves 16 are provided on both sides of the inner wall of the placement compartment 2. Pull rings 17 are provided at the front of the placement rack 3. Fixing holes 18 are provided on both sides of the pull rings 17. Fixing bases 19 are provided on both sides of the front of the placement compartment 2. Fixing screws 20 are inserted inside the fixing bases 19. The placement rack 3 is fixedly connected to the guide sliders 15. The guide sliders 15 are adapted to the guide grooves 16. The placement rack 3 is fixedly connected to the pull rings 17. The bracket body 1 is fixedly connected to the fixing bases 19. The fixing holes 18 are threadedly engaged with the fixing screws 20.

[0038] With the above solution: when in use, rotate the fixing screw 20. Since the fixing hole 18 is threadedly engaged with the fixing screw 20, the fixing screws 20 on both sides move backward under the action of the thread. Loosen the pull ring 17 and pull the pull ring 17 to pull out the single placement rack 3 along the guide slide groove 16 under the action of the guide slider 15.

[0039] Working principle:

[0040] First, during use, the suction tube is inserted into the suction tube placement slot 4. The suction tube is pressed down, causing the movable base column 5 to move down. Since the movable rod 8 is connected to the movable base column 5 and the clamping plate 9 respectively, the clamping plates 9 on both sides move towards each other along the support slide rod 10 under the action of the movable rod 8, clamping and fixing the lower part of the suction tube. When the clamping plates 9 on both sides move towards each other, they squeeze the limiting block 12 to the right. When the limiting groove 11 is aligned with the limiting block 12, since the limiting block 12 is elastically connected to the placement rack 3 through the limiting spring 14, the limiting block 12 is pushed into the limiting groove 11 under the elastic force of the limiting spring 14, completing the limiting and fixing of the clamping plate 9.

[0041] Secondly, when it is necessary to release the blood collection tube, pull the U-shaped lever 13 to move the limiting block 12 to the right away from the limiting groove. Since the movable bottom column 5 is elastically connected to the placement rack 3 through the support spring 7, the movable bottom column 5 is pushed upward under the action of the support spring 7, so that the clamping plates 9 on both sides move backward under the action of the movable rod 8, thereby releasing the blood collection tube.

[0042] Finally, when in use, rotate the fixing screw 20. Since the fixing hole 18 is threadedly engaged with the fixing screw 20, the fixing screws 20 on both sides move backward under the action of the thread. Loosen the pull ring 17 and pull the pull ring 17 to pull out the single placement rack 3 along the guide groove 16 under the action of the guide slider 15.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
