Problems solved by technology

Cause and prolong patient pain, even cause patient urethral injury due to continuous friction and pressure
And because there are many glands and tissues nearby, it is easy to cause various complications
[0004] Based on the above reasons, the discomfort and pain of male patients are more significant during catheterization, and there are certain intraoperative complications. It is good, and requires a high professional level and experience of the operator, and it is difficult to solve the adverse effects of pubic curvature on urinary catheterization

Embodiment 3

[0037] Embodiment 3: Use the catheter of Embodiment 1 to perform male urinary catheterization. The operation steps include the following operations: the patient's legs are bent and abducted, and an oilcloth or middle sheet is placed under the buttocks. The patient first washes the vulva with soap solution; and opens the foreskin to wash. Povidone iodine or 0.1% bromogeramine was used to disinfect the urethral opening and vulva from the inside to the outside. Wrap the penis with a sterile towel, exposing the urethral opening. The operator wears sterile gloves, holds the penis with the thumb and second finger of the left hand, and lifts the penis up to make the anterior curvature of the pubic bone disappear, so that the front end of the catheter 1 is exposed 1.5 cm from the front end of the guide part 2, and the right hand is pinched and coated with The guide tube of sterile lubricating oil (synchronized with catheter 1) is slowly inserted into the urethra. When inserting, the ...

Abstract

The invention discloses a bend-guided male urethral catheter and mainly relates to the technical field of clinical male catheterization. The bend-guided male urethral catheter includes a catheter, theoutside of the catheter is sleeved with a flexible guide pipe, the guide pipe includes a guide portion and a connecting portion which are connected in sequence, the guide portion is close to the front end of the catheter, 4-8 notches are distributed in one side of the guide portion in the length direction, one side of the guide portion provided with a notch is provided with an air bag chamber, the air bag chamber adapts to the length of the guide portion, the connecting portion is provided with an air inflation channel in the length direction, the front end of the air inflation channel is communicated with the air bag chamber, and the rear end of the air inflation channel is provided with an air nozzle connector. The bend-guided male urethral catheter has the advantages that the situationthat the catheter is in continuous friction with the pubis bent portion of the urethra in the insertion process, the damage to the urethra during an operation is greatly reduced, and patient pain andintraoperative complications are reduced.

Description

technical field [0001] The invention relates to the technical field of clinical male urinary catheterization, in particular to a curved guiding type male urethral catheter. Background technique [0002] Bladder indwelling catheterization refers to the method of inserting a sterile catheter through the urethra into the bladder to drain urine under strict aseptic operation, and leaving the catheter in the bladder to drain urine. It is a common clinical nursing operation in cooperation with preoperative and postoperative diseases, as well as urinary system diseases. Since the male urethra starts from the internal urethral opening of the bladder and ends at the external urethral opening of the glans penis, the total length is about 18 to 20 cm, and it has the characteristics of "one long, two curved, and three narrow". Among them, the subcurvature of the pubic bone in the second curve is located below the pubic symphysis, and the depression is upward, including the beginning of...
