Description

A new type of catheterization device

technical field

The invention relates to the technical field of medical supplies, in particular to a novel urinary catheterization device.

Background technique

Clinically, many coma, paralysis, concussion, stroke and postoperative patients, etc., most of them are accompanied by urination obstacles, and indwelling catheterization has become a common means to solve the urination disorders of the above-mentioned patients.

The catheterization device used in traditional indwelling catheterization consists of a catheter inserted into the urethra and a urine collection bag connected to the lower end of the catheter. Its structure is simple, but it has the following disadvantages:

1. The urinary catheter is generally made of soft silicone rubber catheter or natural rubber latex. During the catheterization process, the urinary catheter is often twisted and blocked, which fails to achieve the expected purpose of treatment, which not only delays It reduces the timing of treatment, increases the suffering of patients and the chance of urinary tract infection, and also increases unnecessary workload for medical staff.

2. Because the existing catheter is directly connected to the patient, the catheter fixation effect is not good, and the catheter often slips, twists, etc., causing abnormal situations in the catheterization of the patient.

3. During the use of the urinary catheter, the scale of the medical staff is not easy to grasp when operating, and it is easy to make the catheter excessively extend into the patient's body, causing pain to the patient;

4. During the catheterization process, the flow rate is not well controlled, and it is easy to cause pain to the patient.

5. When the urine collection bag is used, the urine collection bag is usually hung on the hook. When it is used without the hook, the patient needs to hold it by hand, which is not convenient for the patient to use. If the hook is set on the edge of the bed, the hook is easy to scratch the person. Nursing jobs for medical staff have also been increased.

6. The urine collection bag only has the function of storing urine. When the urine in the bag reaches a certain value, if it is not discharged in time, it may cause urine backflow, causing the patient to be unable to urinate normally, and at the same time pollute the catheter. Therefore, patients need nurses to monitor the amount of urine in the bag in real time during use, and to process it in time, which is inconvenient to use, especially at night, and it is a double test of physical strength and spirit for nurses or accompanying staff. However, the existing liquid level alarm is easy to pollute the urine, which affects the accuracy of subsequent urine detection.

Many of the above factors are not conducive to clinical urine drainage, so a new type of catheterization device is urgently needed to meet the needs of patients for efficient and safe catheterization.
