Male built-in urethral catheterization device

Abstract

The invention provides a male built-in urethral catheterization device, and relates to the field of catheters. The male built-in urethral catheterization device comprises a built-in sleeve, a sealingstructure, a movable plug body and an extrusion structure, wherein the sealing structure is fixed on the inner wall of the built-in sleeve, and the sealing structure is provided with a sealing part matched with the movable plug body; the movable plug body is movably arranged in the built-in sleeve along the length direction of the built-in sleeve, the movable plug body has a closed state and an open state, the movable plug body is in sealing fit with the sealing part in the closed state, and the movable plug body is separated from the sealing part to form a flow guide gap in the open state; and the built-in sleeve comprises an extrusion deformation part, the extrusion structure is arranged on the extrusion deformation part, the extrusion structure is provided with an abutting end which moves along the radial direction of the built-in sleeve, and the abutting end is used for abutting against the movable plug body to move towards the open state. By utilizing the cooperation between the movable plug body and the sealing structure, the effect of effectively sealing a urethral catheterization channel can be achieved, and the problem of urine leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of urinary catheters, in particular to a male built-in urinary catheterization device. Background technique [0002] For male patients with bladder disease, it is often impossible to urinate normally. The traditional method is to insert a catheter into the patient's body and use the catheter to drain the urine into a urine bag for storage. However, the insertion and removal of the catheter is easy to cause bacteria infection etc. [0003] Subsequently, a Chinese utility model patent with the authorized announcement number CN210205560U and the authorized announcement date of 2020.03.31 has been developed, which discloses a male built-in hidden urinary catheter, and specifically discloses: a head, a tube and a tube located in the tube Mechanical control valve; the head is fixed in the bladder cavity, and the head is equipped with a urine inlet; the tube is placed in the male urethra, and the end of the tube i...
