Description

A leak-proof liver cirrhosis abdominal drainage tube

Technical Field

The utility model relates to the field of medical instruments, in particular to a leakage-proof liver cirrhosis abdominal cavity drainage tube.

Background Art

Drainage tubes are usually used for surgical drainage. Pus, blood, fluid, etc. accumulated in the human body cavity are guided out of the body through the drainage tubes to prevent postoperative infection or affect wound healing. However, the abdominal drainage tubes currently used in clinical practice often cause the fluid in the abdominal cavity to flow out along the outer wall of the abdominal drainage tube, or the drainage tube falls off when the patient turns over. Therefore, it is very important to handle the sealing and anti-falling problems of the drainage tubes clinically.

For example, the Chinese utility model patent with patent number CN209378113U provides a drainage tube with a self-contained inflatable filling block. After the drainage tube is inserted into the patient's drainage port, it is inflated and filled externally to expand the blockage block and complete the blockage of the drainage port, thereby sealing the drainage port and fixing the drainage tube. However, because the structure adopts inflatable filling, if the filling block leaks, the drainage tube will not play its due role, and the liquid in the drainage process may carry human tissue or flocs. If these substances are not adsorbed, only a single straight-through drainage tube is used, and as the flocs or tissues in the tube increase, blockage may occur in the tube.

In view of the risk of air leakage and the design defects of being unable to handle human tissue or flocs in this type of filling drainage tube, we need to design a drainage tube that can avoid the risk of air leakage and can absorb human tissue or flocs in time.

Utility Model Content

The utility model aims to provide a leakage-proof liver cirrhosis abdominal cavity drainage tube, so as to solve the problems of air leakage in the existing blocking block and excessive impurities in the drainage tube, thus causing blockage.

In order to achieve the above object, the utility model provides the following technical solutions:

A leak-proof liver cirrhosis abdominal drainage tube comprises a first tube body, a second tube body and a connecting hose, wherein the first tube body and the second tube body are respectively connected to two ends of the connecting hose, a filter membrane is arranged inside the connecting hose, and a leak-proof fixing component is arranged outside the first tube body.

Preferably, the anti-leakage fixing assembly comprises eight springs, an elastic blocking block and an adsorption sheet, wherein the adsorption sheet is arranged on the top of the elastic blocking block, and the eight springs are arranged inside the elastic blocking block.

Preferably, the first tube body, the second tube body and the connecting hose are all made of medical silicone material.

Preferably, the filter membrane is made of PTFE.

Preferably, the elastic blocking block is made of medical skin-friendly soft silicone.

Preferably, the adsorption sheet is made of medical absorbent cotton.

The principle and beneficial effects of this technical solution:

Compared with the prior art, this technical solution does not require the blockage to be inflated. The compression spring can be directly placed into the drainage port. After placement, the spring rebounds to achieve the purpose of sealing and blocking. Because the drainage tube is inserted into the blockage, the tube body is also fixed. The design of the internal structure of the connecting hose can not only absorb impurities in the drainage, but also facilitate replacement, and the structure is simple and convenient.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings and implementation modes:

Example:

As shown in Figures 1 and 2, a leak-proof liver cirrhosis abdominal drainage tube includes a first tube body 1, a second tube body 7 and a connecting hose 6. The first tube body 1 and the second tube body 7 are respectively connected to the two ends of the connecting hose 6. A filter membrane 5 is provided inside the connecting hose 6, and a leak-proof fixing component is provided on the outside of the first tube body 1.

Before drainage begins, the two ends of the connecting hose 6 are threadedly connected to the first tube body 1 and the second tube body 7 respectively, and the inside of the connecting hose 6 is transparent. During the drainage process, impurities in the drainage fluid will be adsorbed on the filter membrane 5 inside the connecting hose 6. When there are too many impurities in the filter membrane 5, a new connecting hose 6 can be directly replaced. In mass production, the connecting hose 6 is made of low-cost materials. The structure is simple and easy to implement.

As shown in FIGS. 1 to 2 , the anti-leakage fixing assembly includes eight springs 2 , an elastic blocking block 3 and an adsorption sheet 4 . The adsorption sheet 4 is arranged on the top of the elastic blocking block 3 , and the eight springs 2 are arranged inside the elastic blocking block 3 .

The design of the adsorption sheet 4 can ensure that the excess peritoneal fluid will not seep out at the intubation site, and the spring 2 is arranged inside the elastic blocking block 3, which also makes the elastic blocking block 3 further have telescopic elasticity.

As shown in Figures 1 to 2, the first tube body 1, the second tube body 7 and the connecting hose 6 are all made of medical silicone, the filter membrane 5 is made of PTFE, the elastic blocking block 3 is made of medical skin-friendly soft silicone, and the adsorption sheet 4 is made of medical absorbent cotton.

The selection of medical silicone material ensures the hygienic standards of the first tube body 1, the second tube body 7 and the connecting hose 6. The skin-friendly soft silicone material makes the outer surface of the elastic blocking block 3 soft and elastic enough, and will not cause too much stimulation to the patient when it is placed in the intubation site.

The specific implementation process is as follows:

Before the drainage begins, the first tube body 1 and the second tube body 7 are firstly connected by threading through the connecting hose 6, and then the elastic plugging block 3 is connected to the first tube body 1, and then the elastic plugging block 3 is put into the cannula. Because the diameter size of the elastic plugging block 3 is designed to be "small", "large" and "small", when it is just put into the cannula, the elastic plugging block 3 starts to touch the tissue at the smallest diameter. As the elastic plugging block 3 is gradually put in, it mainly contacts the tissue at the largest diameter. Because the material of the elastic plugging block 3 is skin-friendly soft silicone, it will not cause too much stimulation to the patient. Finally, after reaching the designated position, the elastic plugging block 3 The surrounding of the blocking block 3 stops contacting with the tissue, and the side with the adsorption sheet 4 on the top comes into adsorption contact with the internal tissue. When the drainage tube starts to drain, the drainage fluid is ensured not to leak out because the adsorption sheet 4 and the elastic blocking block 3 are stuck on the inner side of the tissue. Moreover, because the first tube body 1 is covered with the elastic blocking block 3, the first tube body 1 will not shake or fall off easily. As the drainage process progresses, the filter membrane 5 inside the connecting hose 6 is gradually filled with impurities. At this time, the drainage is suspended, the connecting hose 6 is replaced with a new one, and then the drainage is continued. After the drainage is completed, the first tube body 1 is pulled to drive and extract the elastic blocking block 3.

The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and/or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the technical solution of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
