Abstract

The invention provides a urethral catheter and a method. The urethral catheter comprises a head, a middle part and a tail which are sequentially connected, wherein a medicine outlet is arranged at thefront end of the head, the outer side of the head is sleeved with a balloon which can be full after water filling to cover the head, and at least two urethral catheterization ports are formed in thepart which cannot be covered with the balloon; a water injection pipe, a urination pipe and a medicine injection pipe which are connected adjacently are accommodated in the middle part, the medicine outlet is communicated with the medicine injection pipe, the two urethral catheterization ports are communicated with the urination pipe, and the balloon is communicated with the water injection pipe through a water outlet; a water injection cavity, a urethral catheterization cavity and a medicine injection cavity which are in one-to-one correspondence connection with the water injection pipe, theurination pipe and the medicine injection pipe are arranged at the tail. The urethral catheter avoids contact between the tip of the head of the urethral catheter and urinary bladder walls and avoidsirritation of the tip of the head of the urethral catheter to urinary bladders.

Description

technical field [0001] The present disclosure relates to a urinary catheter and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, indwelling catheterization is often required clinically. Urinary catheters are mostly used for patients with dysuria. The catheter is inserted through the urethra into the bladder for urine drainage. However, the currently used urinary catheter, after indwelling the bladder, when the bladder is empty, the tip of the catheter head contacts the bladder wall, which stimulates the bladder wall, which is poorly tolerated by the patient and has a strong sense of foreign body stimulation. Bladder mucosal injury is congested and edema, blood streaks or blood clots often appear in the drained urine, which blocks the catheter, which in turn leads to urinary system diseases. [0004] Therefore need to...
