Abstract

The invention discloses a catheter device which comprises a catheter. An elastic metal guide wire is arranged in the catheter, one end of the elastic metal guide wire is bent, one end of the catheter is supported to be of a bent structure by one end of the elastic metal guide wire, the other port of the catheter is provided with a one-way valve, the other end of the elastic metal guide wire extends out of the catheter from the one-way valve, the other end of the elastic metal guide wire is fixedly connected with an outer cap, and one end of the outer cap is inserted into the one-way valve. The elastic metal guide wire and the one-way valve are added on the basis of an existing catheter, and the elastic metal guide wire makes the catheter have a certain curvature and hardness and smoothly arranged into the bladder on the premise that the urethra is not hurt. In addition, the one-way valve can prevent urine from being automatically drained out of the catheter after the guide wire is pulled out or a drainage bag is not connected, and pollution is avoided.

Description

technical field [0001] The invention belongs to the field of medical auxiliary equipment, in particular to a urinary catheter device. Background technique [0002] The existing urinary catheters are usually made of silica gel or rubber, which are usually soft. When patients with urethral stricture or prostatic hyperplasia often fail to indwell the catheter, the use of metal probes to dilate the urethra or bladder puncture fistula often results in severe pain. The patient causes pain. Contents of the invention [0003] In order to solve the problems in the prior art, the object of the present invention is to provide a urinary catheter device. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts the technical scheme as follows: [0005] A catheter device, including a catheter, an elastic metal guide wire is arranged in the catheter, one end of the elastic metal guide wire is curved, and one end of the catheter is supported...
