Description

Urinary catheter with its own pressure measurement and marking

technical field

The utility model relates to a urinary catheter with self-contained pressure measurement and marked with a scale, belonging to the technical field of medical instruments.

Background technique

Indwelling catheter is a method of inserting a sterile catheter into the bladder through the urethra to drain urine under strict aseptic operation. It is a nursing operation technique commonly used in clinical practice. At present, there is a balloon at the front end of the urinary catheter commonly used in clinical practice. After the urinary catheter is inserted, the balloon is filled by injecting about 20ml of normal saline into the balloon. However, the current urinary catheter has the following defects in actual use: 1. Due to the different tightness of the urethra of each patient, the fixation situation of injecting about 20ml of normal saline will also be different. In order to judge whether the urinary catheter has been fixed, Medical staff usually have to pull out the test by hand after water injection. This operation may damage the urethral mucosa; 2. There is no specific scale on the inserted urinary catheter, and medical staff usually rely on experience to judge the insertion length, and the accuracy is not high; 3 , Indwelling urinary catheter is an iatrogenic way for bacteria to enter the urinary tract. Bacteria around the urethra or anus can enter the urethra along the outer wall of the urinary catheter; in addition, the urinary catheter may also damage the urethra during intubation, so that bacteria Infection of the urethral mucosa.

In view of the above-mentioned first defect, some solutions are to set a pressure sensor in the balloon, and the pressure sensor is connected to the display screen through a wire. However, since the pressure sensor has a certain volume, the pressure sensor is placed in the balloon that needs to be inserted into the urethra.
