Description

Technical Field

[0001] The present application relates to the technical field of urinary catheters, and in particular to a urinary catheter insertion auxiliary device. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine. According to the circumference of the outer diameter, it is usually divided into 13 specifications from 6F to 30F. The four commonly used catheters for adults are 12F, 14F, 16F, and 18F (F is the abbreviation of French, which means the outer circumference in millimeters. The conversion formula is: F=2πr, and the rough conversion is: F (mm) = 3 times the outer diameter (mm)).

[0003] The existing patent (publication number: CN209092493U) discloses a disposable catheterization auxiliary guidewire, including a guidewire packaging bag, a catheter and an auxiliary guidewire body inserted into the catheter, the auxiliary guidewire body includes a guidewire hose, a first fixed rubber plug of the guidewire hose, a second fixed rubber plug is fixedly provided at one end of the guidewire hose away from the first fixed rubber plug, an inflation hole is opened at the center of the first fixed rubber plug, a connecting belt is connected to the circumferential surface of one end of the guidewire hose close to the first fixed rubber plug, and a limiting pad is connected to the end of the connecting belt away from the guidewire hose.

[0004] The above-mentioned comparative document points out that the utility model is convenient for storage and carrying by means of the inflatable hose, and can also reduce the utilization rate of space; the inflatable hose can be inflated through the inflatable hole, so that the inflatable hose becomes straight and is inserted into the catheter. After use, the outer wall of the inflatable hose can be punctured with a needle to discharge the internal gas, and then put into the trash can without taking up space. However, the device must be pulled out after the wire-assisted catheter enters the human body. During use, most patients have inflammation in the bladder, and blood and pus may be produced during urination, which can easily cause blockage of the catheter. Generally, it can only be cleaned with saline. If the blockage is very serious, the cleaning effect is not good, and the catheter can only be replaced, which will cause the patient pain of secondary intubation. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a catheter insertion auxiliary device, which has the advantages of being easy to clean the catheter, etc., and solves the problem that the wire-assisted catheter must be pulled out after entering the human body. During use, most patients have inflammation in the bladder, and blood and pus may be produced during urination, which can easily cause the catheter to be blocked. Generally, it can only be cleaned with saline. If the blockage is very serious, the cleaning effect is not good, and the catheter can only be replaced, which will cause the patient to suffer from secondary catheterization.

[0007] According to the above scheme, a fixable auxiliary steel wire is arranged in the catheter. First, the auxiliary steel wire is passed into the catheter. The fixing frame at one end of the auxiliary steel wire passes through the groove and is rotated and fixed on the drainage head. Then, the catheter is driven into the patient's body. If a blockage occurs in the catheter, the auxiliary steel wire can be rotated to match the fixing frame with the groove, and the auxiliary steel wire can be pulled out. In the process of rotating and pulling out the fixing frame, the blockage in the catheter can be cleared, which can solve some blockages that are difficult to clean. In the process of cleaning, the catheter does not need to be pulled out, which reduces the patient's pain and is relatively simple to clean.

[0008] Furthermore, one end of the urinary catheter is fixedly connected to a water bag.

[0009] Through the above scheme, the water bag is provided to place the urinary catheter in the human body to prevent it from slipping out.

[0010] Furthermore, a groove is provided inside the liquid discharge head.

[0011] Through the above scheme, the groove is provided to facilitate the removal of the auxiliary steel wire.

[0012] Furthermore, a flushing connector is fixedly connected to one side of the urinary catheter.

[0013] According to the above scheme, the inside of the urinary catheter is cleaned by providing a flushing joint connected to the internal pipeline of the urinary catheter.

[0014] Furthermore, a one-way valve is fixedly connected to one side of the urinary catheter.

[0015] Through the above scheme, by setting a one-way valve, water is filled in the water bag connected to the pipe connected to the one-way valve by the water filler.

[0016] Furthermore, a leakage hole is provided on the surface of the fixing frame.

[0017] Through the above scheme, by setting the leakage hole, blockage and urine leakage can be prevented.

[0018] Furthermore, a sealing groove is provided on one side of the urine bag interface.

[0019] Through the above scheme, urine leakage is prevented by arranging the sealing groove to correspond to the sealing pad.

[0020] Furthermore, four fixing buckles corresponding to the fixing grooves are fixedly connected to one side of the urine bag interface.

[0021] Through the above solution, a fixing device is formed by arranging the fixing buckles to correspond to the fixing grooves.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The catheter insertion auxiliary device is composed of a fixable auxiliary steel wire arranged in the catheter. First, the auxiliary steel wire is passed into the catheter, and a fixing frame at one end of the auxiliary steel wire passes through a groove and is rotated and fixed on a drainage head, and then the catheter is driven into the patient's body. The device can not only assist the catheter to enter the patient's body, but also when a serious blockage occurs in the catheter, the auxiliary steel wire can be rotated to match the fixing frame with the groove, so that the auxiliary steel wire can be pulled out. In the process of rotating and pulling out the fixing frame, the blockage in the catheter can be cleared, and some blockages that are difficult to clean can be solved. In the process of cleaning, the catheter does not need to be pulled out, which reduces the patient's pain and is relatively simple to clean. BRIEF DESCRIPTION OF THE DRAWINGS
