Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an abdominal drainage tube capable of preventing from falling off. Background Art

[0002] An abdominal drainage tube (abdominal drainage catheter) is a medical device used to drain fluid or pus in the abdominal cavity, usually for the treatment of abdominal diseases or complications after surgery. The main function of the drainage tube is to help drain the fluid in the abdominal cavity, prevent fluid accumulation or infection, and promote recovery. When using the drainage tube, you need to pay attention to prevent infection, tube blockage and other problems. Patients need to undergo regular examinations and care in the hospital. If the drainage tube is abnormal or there are other complications, it may be necessary to adjust or replace the drainage tube.

[0003] In the prior art, a patent with publication number "CN202569156U" discloses an anti-falling abdominal drainage tube, which is provided with two circles of air bag structure, which can tightly clamp the patient's skin, thereby fixing the drainage tube and preventing it from falling off, eliminating the pain caused to the patient by suturing and fixation. The air bag is wrinkled in a natural state, does not increase the thickness of the tube wall, does not increase the difficulty of intubation, is easy to use, has a simple structure, and is low in cost. It is suitable for widespread promotion and use in clinical practice, and solves the problem that the current abdominal drainage tube is easy to fall off after being inserted into the abdominal cavity due to the smooth wall of the drainage tube.

[0004] However, the above device still has the following problems during implementation: the drainage tube usually enters the body through the wound, and the skin at the wound site needs to be relied upon to support the drainage tube during fixation. However, the skin at the wound site is relatively fragile, especially when the wound is not completely healed or the wound surface is large. This fixation method that relies on the skin will cause the edge of the wound to be subjected to certain pressure or traction, increasing the risk of secondary injury.

[0005] For this reason, we provide a kind of peritoneal drainage tube that prevents falling off, in order to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a peritoneal drainage tube that prevents falling off. Through the cooperation of a fixing component, an anti-falling component and an air storage component, the problem in the prior art that when the drainage tube is fixed, it needs to rely on the skin of the wound site to support the drainage tube, which is prone to secondary damage.

[0007] To solve the above technical problems, the present invention is implemented through the following technical solutions.

[0008] The present invention discloses an abdominal drainage tube for preventing falling off, comprising a fixing belt, a supporting tube installed inside the fixing belt, and a guide tube arranged inside the supporting tube; a fixing component is arranged on one side of the supporting tube, and the fixing component comprises a sealing tube, the sealing tube is fixedly connected to the surface of the supporting tube, an adjusting tube is sleeved on the surface of the supporting tube, a rubber plug is arranged inside the adjusting tube, a pushing block is fixedly connected to the inside of the adjusting tube, an airbag strip is arranged on one side of the pushing block, and the guide tube is fixed by the fixing component; an anti-slipping component is arranged on the other side of the supporting tube, and the anti-slipping component comprises an insertion tube, the insertion tube is fixedly connected to one end of the supporting tube, an airbag ring is fixedly connected to the surface of the insertion tube, and the position of the guide tube is limited by the anti-slipping component.

The connecting sleeve 19 is fixed to the surface of the guide tube 3 by the medical tape 20. When the elastic rope 22 is fixed to both ends of the guide tube 3, the guide tube 3 can have the function of elastic expansion and contraction, and provide a certain buffer space when the patient turns over and moves. The first Velcro 29 and the second Velcro 30 are designed as male and female stickers, and the length of the fixing belt 1 can be fixed during adhesion.

[0042] The working principle of the present invention is as follows: before the patient inserts the guide tube 3, the medical staff can first insert the guide tube 3 into the adjusting tube 5, the supporting tube 2 and the insertion tube 9, and then insert the guide tube 3 into the patient's body. After the guide tube 3 is inserted into the designated position, the supporting tube 2 is tied to the patient's waist position using the fixing belt 1 to play a role in connecting and supporting. Then the adjusting tube 5 is manually rotated, and the adjusting tube 5 drives the pushing block 7 to push the rubber plug 6, so that the rubber plug 6 fits with the guide tube 3. The extension and retraction movement of the guide tube 3 is limited by friction, and the connection stability of the guide tube 3 can be improved.

[0043] When the adjusting tube 5 rotates, the piston ring 13 is pushed by the threaded action of the adjusting tube 5 and the sealing tube 4. The piston ring 13 compresses the gas inside the sealing tube 4 while moving, so that the compressed gas is injected into the airbag ring 10 through the air supply pipe 16 to inflate the airbag ring 10. After the airbag ring 10 is inflated, it props up the inside of the patient's skin to stabilize the wound, avoid secondary strain on the wound during activities, and improve the protective effect.
