Since there is a top drainage probe with a length of at least 3cm at the front end of the traditional urinary catheter balloon, and the bladder of patients with indwelling catheterization is mostly empty or semi-empty. Localized inflammatory reaction of bladder mucosa caused by extrusion and scratching within the range (approximately 2cm in diameter and irregular shape), mucosal hypere

Abstract

The invention discloses a catheter. The catheter comprises an outer pipe body which is axially provided with a urethral catheterization channel and a center pipe which is axially provided with a through channel, the center pipe is arranged in the channel of the outer pipe body, and the two ends of the center pipe extend out of the outer pipe body separately and can axially move along the outer pipe body; the center pipe stretching out of the front end of the outer pipe body becomes harder gradually in the direction of the outer pipe body from front to back. The invention further provides a male catheter which is provided with a center pipe, an opening is formed in the front end of the center pipe, the center pipe becomes harder gradually in the direction close to the outer pipe body, thenthe center pipe can conveniently enter the bladder along a bending part of the male urethra, the position of the outer pipe body can be determined, and implantation of the catheter is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, the invention relates to a urinary catheter and a male urinary catheter. Background technique [0002] Urinary catheterization is one of the common medical operations in clinical practice. It is suitable for urinary retention caused by many reasons such as lower urinary tract obstruction or neurogenic bladder. Urinary catheterization is also used in rescuing critically ill patients, perioperative preparations, and intravesical medications. Perfusion or bladder irrigation, etc. The urinary catheter can also be used for drainage such as cystostomy and pyelostomy. [0003] Due to the complex path of the male urethra, the insertion of the male urinary catheter is more complicated and difficult, and has higher requirements for the structure of the urinary catheter. The male urethra forms three narrows, three widens, and two bends in its long and complex course. Three ...
