Description

Anti-loss and anti-seepage catheterization device

technical field

The invention relates to a medical auxiliary device, in particular to a damage-proof and seepage-proof urinary catheterization device.

Background technique

Disposable catheters currently in use include common disposable double-lumen catheters for drainage of urine and triple-lumen catheters for flushing. Common double-lumen catheters are simply used for indwelling catheters Drainage of urine, three-lumen catheter is generally indwelling after urological surgery to flush the bladder, etc.

The commonly used clinical catheter is a double-lumen single-balloon silicone catheter. There is a urination hole on the side wall of the head and an air bag under the urination hole. There is a urination hole at the tail. After it is inserted, it is more difficult to urinate. . This kind of catheter with a balloon is mainly used to prevent falling off. Its principle is to inflate the balloon channel with air or water to inflate the balloon, thereby fixing the catheter in the bladder, and the urine in the bladder flows out of the body through the urination hole . In use, due to various reasons, urine leakage will occur around the tube body, and urine will ooze out with the catheter. When the urine is discharged to a certain extent, the incision of the catheter will suck and block the bladder mucosa, which will cause damage to the patient. Since the lining of the bladder is sucked into the incision by the suction force of the catheter into the urinal hole, it causes damage and causes physical pain to the patient. It not only brings inconvenience to nursing work, but also affects the quality of life of patients.

After the catheter is inserted into the bladder, if it is not regularly cleaned and cleaned, it is easy to breed bacteria and cause infection. Difficulty completing catheter care cleaning on time during home care.

Monitoring intra-abdominal pressure is a strong basis for clinical diagnosis and guiding treatment, especially continuous and dynamic monitoring. Changes in intra-abdominal pressure are usually reflected by bladder pressure. At present, the commonly used intravesical pressure monitoring is mainly measured by the three-way method, which requires repeated intubation and complicated operation, which fails to achieve the purpose of monitoring and increases the pain of the patient.

In view of the above problems, it is necessary to provide a urinary catheter device capable of preventing damage to bladder inner wall tissue and leakage of urine, and even capable of monitoring bladder internal pressure.

As a further improvement of the above technical solution:

The connection between the inflation channel and the bladder fixing airbag is an inverted conical surface.

A suction ring is sheathed on the outer wall of the urinary catheter below the fixed bladder.

The liquid suction ring is set as an elastic ring.
