Problems solved by technology

The current conventional method is to dilate the urethra with a metal urethral dilator, which usually expands the urethra multiple times from small to large sizes, and then inserts a thicker catheter for a longer period of support to promote the healing of the injured mucosa. This kind of operation takes a long time, which not only increases the pain of the patient, but also makes it inconvenient to keep the metal urethral dilator during catheterization, and it is still difficult to insert a thick catheter

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention comprises a urethral dilation drainage tube 1, a support tube 2 and a guide wire 3;

[0036] The urethral expansion drainage tube 1 is composed of a head 4, a body 5 and a tail 6; the length of the drainage tube 1 is 45cm, and the diameter is 8Fr; wherein,

[0037] The head 4 is a single pigtail tube with a length of 6 cm. There is a channel 7 inside and two side holes 8 are arranged on the pipe wall. The front end of the head 1 is tapered. The fixed traction line 9 provided on the outer wall passes through the single pigtail The traction line channel hole provided at the end of the pipe enters the channel 7;

[0038] The body part 5 is a double-way tube, with a channel 10 and a channel 11 inside, the channel 10 communicates with the channel 7, a cylindrical air bag 12 is arranged on the tube wall, the air bag 12 i...

Abstract

The invention provides a urethral stenosis dilatation drainage tube, and belongs to the technical field of medical device manufacturing. The drainage tube includes a urethral dilatation drainage tube,a supporting tube and a guide wire; the urethral dilatation tube is composed of a head, a body and a tail, the head is a single pigtail tube, a channel is arranged in the single pigtail tube, the tube wall is provided with side holes, the front end of the head is tapered, the outer wall is provided with a fixing traction line, the tail of the single pigtail tube is provided with a traction line channel hole, and a traction line enters the channel through the hole; the body is a double-channel tube, and a cylindrical airbag is arranged and fixed on the tube wall; the tail end of the tail is provided with a ureteral bag connector, a traction line buckle and a water injection joint; the supporting tube is a single-channel tube, the head end is a metal tube, and a screw cap at the tail is screwed on a tail joint of the urethral dilation drainage tube; and the body of the guide wire is rigid, and the head end is prepared from a soft material. The urethral stenosis dilatation drainage tubeachieves the following beneficial effects: the drainage tube is simple to operate, easily passes through stenosis urethra, and does not cause secondary damage to the urethra.

Description

technical field [0001] The invention belongs to the technical field of medical device manufacturing, and relates to a dilation drainage tube for urethral stricture. Background technique [0002] Urinary catheter is a common medical device in clinical practice. It is inserted into the bladder through the external opening of the urethra to drain urine out of the body. Its main function is to accurately record urine volume, facilitate drainage and flushing, and play an important role in clinical practice. [0003] The catheter materials currently used mainly include silica gel, rubber, EVA, PVC, etc., and its tube body is soft. For patients with diseases such as urethral stricture, benign prostatic hyperplasia, prostatitis, prostate tumor, and urethral injury, the inner diameter, course, and curvature of the urethra change. The resistance in the conventional indwelling catheter is relatively large, and a large force is required, but the violent intubation not only brings great...
