Improved catheter

Technical Field

The utility model relates to a catheter technical field especially relates to an improved form catheter.

Background

The catheter is the most common clinical medical appliance, and urine can be drained from the bladder to the outside of the body after being placed into a human body from the urethra; can be taken out after one-time urine drainage, and can also be left for a long time for multiple times of drainage.

The problem of unsmooth drainage can occur during the retention period of the catheter, which is generally called catheter blockage, the clinical catheter blockage is generally understood to be the blockage of the inner cavity of the catheter, but is actually the blockage of a urine inlet, so the common mode of dredging the inner cavity of the catheter by the guide wire has poor effect; the other method is negative pressure suction, common syringes are used for repeated suction, although the operation is complex, the connection between the catheter and the drainage bag needs to be frequently opened, and the pollution at the joint of the catheter and the drainage bag is an important reason for the pollution in the cavity of the catheter and the retrograde infection of the lower urinary tract; the catheter is required to be pulled out when the blockage cannot be eliminated, the blockage embedded in the urine inlet is taken out at the same time, the catheter with larger inner diameter is replaced and placed in again, and great pain is brought to a patient.
