Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a neurosurgical drainage clip. Background Technology

[0002] A drainage tube is a clinical medical device used to drain fluids, blood, gas, or pus from a patient's internal or external cavities into a drainage bag. The drainage tube helps drain and remove abnormal fluid accumulation in the body, keeps the wound dry, reduces the risk of infection, and promotes wound healing. When the drainage bag needs to be changed, the drainage tube should be clamped to prevent leakage of drainage fluid.

[0003] However, in the existing technology, when the drainage bag needs to be replaced, medical staff need to use hemostatic forceps to clamp the drainage tube. However, the use of hemostatic forceps will shorten the life of the drainage tube, the hemostatic forceps cannot stably fix the position of the drainage tube, the drainage tube is easily pulled, and the hemostatic forceps are inconvenient to adjust the flow rate of the drainage tube. Utility Model Content

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides, for example Figures 1-4 As shown, a neurosurgical clinical drainage clip includes: a clip body 1, a clamping cavity 2 at the inner end of the clip body 1, the bottom end of the clamping cavity 2 being arc-shaped, a rubber pad 4 fixedly installed on the inner wall of the bottom end of the clamping cavity 2, an opening 3 at one end of the clip body 1, the opening 3 communicating with the interior of the clip body 1, the drainage tube entering the clamping cavity 2 through the opening 3, a hand-tightening bolt 5 threadedly connected to the upper end of the clip body 1, a pressure plate 6 slidably connected to the inner end of the clamping cavity 2, the left and right ends of the pressure plate 6 being slidably connected to the inner walls of the left and right ends of the clamping cavity 2 respectively, the lower end of the pressure plate 6 being arc-shaped and a rubber pad 7 fixedly installed thereon, the lower end of the hand-tightening bolt 5 passing through the upper end of the clip body 1 into the clamping cavity 2 and rotatably connected to the upper end of the pressure plate 6, the pressure plate 6 can be driven to move up and down in the clamping cavity 2 by turning the hand-tightening bolt 5, thereby changing the distance between the rubber pad 7 and the rubber pad 4, clamping the drainage tube, and changing the flow rate of the drainage tube;

[0023] A sleeve 11 is fixedly installed at the end of the clamp body 1 away from the opening 3. The clamp body 1 is connected to a fixed clamp 14 via a support frame 13. The fixed clamp 14 is U-shaped. A movable plate 16 is slidably connected inside the fixed clamp 14. One end of the movable plate 16 is slidably connected to the inner wall of one end of the fixed clamp 14. A hand-tightening bolt 35 is threadedly connected to the bottom end of the fixed clamp 14. The upper end of the hand-tightening bolt 315 passes through the bottom end of the fixed clamp 14 and is rotatably connected to the lower end of the movable plate 16. By turning the hand-tightening bolt 315, the movable plate 16 can be driven to move inside the fixed clamp 14. Anti-slip pads are fixedly installed on the upper end of the movable plate 16 and the upper inner wall of the fixed clamp 14. By first moving the movable plate 16 to the lowest point of the fixed clamp 14, then fitting the fixed clamp 14 onto the bed frame, and then turning the hand-tightening bolt 315 to drive the movable plate 16 to move, the anti-slip pads are brought into close contact with the window frame, thereby fixing the fixed clamp 14.

[0024] Specifically, in use, first fix the clamp 14 to the hospital bed, then fix the lower end of the support frame 13 to the clamp 14, and fix the upper end of the support frame 13 to one end of the clamp body 1. Next, insert the drainage tube into the clamp cavity 2 from the opening 3, then tighten the hand-tightening bolt 5 to drive the pressure plate 6 to move down, and fix the drainage tube through the rubber pad 4 and the rubber pad 7. Adjust the position of the pressure plate 6 according to the condition of the neurosurgical patient, and then adjust the flow rate of the drainage tube.

[0025] like Figure 2 and Figure 3 As shown, in some embodiments, a sliding cavity 8 is provided on the inner wall of the bottom end of the opening 3. A limiting plate 9 is slidably connected in the sliding cavity 8. Slopes are provided on both the left and right sides of the upper end of the limiting plate 9. A spring 10 is fixedly installed on the lower end of the limiting plate 9. The lower end of the spring 10 is fixedly connected to the inner wall of the bottom end of the sliding cavity 8. When the spring 10 is in a balanced state, the upper end of the limiting plate 9 is located in the opening 3. More specifically, when it is necessary to clamp the drainage tube, the drainage tube is pulled into the opening 3. The drainage tube contacts the slope at the upper end of the limiting plate 9, pushing the limiting plate 9 downward. The limiting plate 9 slides into the sliding cavity 8 by squeezing the spring 10, thereby allowing the drainage tube to enter the clamping cavity 2. Then, the limiting plate 9 is reset under the reaction force of the spring 10, limiting the drainage tube.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, a second hand-tightening bolt 12 is threadedly connected to one end of the sleeve 11 via a threaded cylinder. The sleeve 11 is fitted onto the upper end of the support frame 13, and the inner end of the second hand-tightening bolt 12 can contact the upper end side wall of the support frame 13. By tightening the second hand-tightening bolt 12, it is convenient to assemble and disassemble the support frame 13 and the clamp 1. The sleeve 11 can be fitted onto different positions on the upper end of the support frame 13, which facilitates the adjustment of the height of the clamp 1.

[0027] A fixing block 17 is fixedly installed on the outer end of the fixing clamp 14. A limiting cylinder 18 is fixedly installed on the upper end of the fixing block 17. A hand-tightening bolt 19 is threadedly connected to the outer wall of the limiting cylinder 18 through a threaded sleeve. The lower end of the support frame 13 is inserted into the limiting cylinder 18. The inner end of the hand-tightening bolt 19 can contact the outer wall of the support frame 13. The support frame 13 and the fixing clamp 14 can be disassembled and assembled by turning the hand-tightening bolt 19. More specifically, by inserting the upper end of the support frame 13 into the sleeve 11 and turning the hand-tightening bolt 12, inserting the lower end of the support frame 13 into the limiting cylinder 18, and rotating the support frame 13 to adjust the clamp 1 to a suitable position and then turning the hand-tightening bolt 19, the clamp 1 can be fixed, which makes it easy to adjust the position of the clamp 1.

[0028] Working principle:

[0029] Step 1: First, fix the fixing clip 14 to the bed frame of the hospital bed. Slide the sleeve 11 onto the upper end of the support frame 13 and move it to the appropriate position. Then tighten the second hand-tightening bolt 12. Insert the lower end of the support frame 13 into the limiting sleeve 18. Rotate the support frame 13 to adjust the clamp 1 to the appropriate position and tighten the fourth hand-tightening bolt 19 to fix the clamp 1.

[0030] Step 2: Next, insert the drainage tube into the clamping cavity 2 through the squeeze limiting plate 9 from the opening 3. Then, tighten the hand-tightening bolt 5 to drive the pressure plate 6 to move down, and fix the drainage tube through the rubber pad 4 and the rubber pad 7. Adjust the position of the pressure plate 6 according to the patient's condition, and then adjust the flow rate of the drainage tube.
