The utility model discloses further set up to: the catheter body is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC).
Through above-mentioned technical scheme, natural rubber, silicon rubber or polyvinyl chloride (PVC) are soft state, are soft material, and when using, the head can rotate around the splice bar, opens the second and washs the mouth.
The utility model discloses further set up to: the first cleaning opening is provided with a plurality of first cleaning openings along the axis direction of the joint, and the first cleaning openings form a straight line.
Through above-mentioned technical scheme, it has a plurality of to set up the washing mouth for the cleaning performance of washing mouth is better.
The utility model discloses further set up to: the connector is cylindrical, and the diameter of the end, far away from the catheter body, of the connector is smaller than the diameter of the end, close to the catheter body, of the connector.
Through above-mentioned technical scheme, the diameter that sets up the joint is close to the inside one end of urethra less for the packing force of head in the joint is bigger, makes things convenient for the rotation of head, conveniently opens the second and washs the mouth.
The utility model discloses further set up to: and a convex ring is arranged on the inner wall of the interface channel of the joint.
The utility model discloses further set up to: one or more convex rings are arranged.
Through above-mentioned technical scheme, set up the bulge loop, the bulge loop can block opening gap department, and the convenience is when the somatic part of catheter body is pulled out, and the head of catheter body rotates, has further made things convenient for opening of second washing mouth.
The utility model discloses further set up to: the catheter body is cylindrical.
To sum up, the utility model discloses following beneficial effect has:
(1) the opening gap is formed in the peripheral side of the catheter body, so that the second cleaning opening can be opened from the gap, and the purpose of conveniently guiding cleaning liquid for cleaning is achieved;
(2) the end, close to the interior of the urethra, of the joint is smaller in diameter, so that the pressing force of the head in the joint is larger, the head can rotate conveniently, and the second cleaning port can be opened conveniently;
(3) through setting up the bulge loop, the bulge loop can block opening gap department, and the convenience is when the somatic part of catheter body is pulled out, and the head of catheter body rotates, has further made things convenient for opening of second washing mouth.
