Self-control urethral catheter

Abstract

The invention discloses a self-control urethral catheter. A switch assembly is arranged at a urethral catheterization cavity hole of a main catheter body; the switch assembly comprises a shell, a rotating core and a handle; a cavity allowing a rotating core to be arranged in a matched mode and capable of rotating is formed in the shell, the upper side and the lower side of the cavity run through outwards to form main flow channels allowing urine to pass through; a urination flow channel and a pressure flow channel with different angles are formed in the rotating core, and a pressure film is arranged in the pressure flow channel and used for rupture urination when hydraulic pressure exceeds the bearing capacity of the pressure film; when the rotating core rotates, one of the urination flowchannel and the pressure flow channel selectively conducts the upper main flow channel and the lower main flow channel, and the handle is connected with the rotating core and extends out of an inserting pipe to be driven by people to rotate. The functions of opening and closing an urination pipeline and a safety pressure pipeline originally are achieved through one pipeline, urine control is achieved, the pipeline structure is simplified, simplification of an external pipeline and a fixing structure of a human body after the urethral catheter is arranged is facilitated, the treatment environment is simplified, and troubles brought to doctors or patients in the medical treatment process due to an original complex structure are avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a self-control urinary catheter. Background technique [0002] A urinary catheter is a tubular medical device inserted through the urethra into the bladder to drain urine. The existing urinary catheter basically has a two-layer structure, one layer of large space is used for catheterization, and one layer of small space is used for inflation. After being inserted into the bladder, the bladder is inflated and inflated, and the catheter is positioned in the bladder to continuously catheterize the patient. The inflatable space is equipped with an air hole externally. There are generally two ways to set up the catheterization space externally. One is to set only the switch hole, and to open or close the switch hole artificially to perform regular urination. This method is not safe. If it is not timely Urination will cause excessive bladder pressure; therefore, another way is to set...

AI Technical Summary

Problems solved by technology

However, when the switch hole and emergency hole are installed, the processing cost of the catheter increases, and the external structure is also complicated. Two sets of pipes or Y-shaped pipes are installed to connect to the urine collection bag for external connections. The more complicated the structure The more unfavorable it is to fix the pipeline, it will bring troubles to doctors or patients during medical treatment
