Description

Mechanical controllable catheter

Technical Field

The utility model belongs to the technical field of the catheter technique and specifically relates to a mechanically controllable catheter.

Background

Acute urinary retention is a disease which is common clinically, especially common in old men, and the common disease is urinary mechanical obstruction and drug-related urinary retention. The common symptoms and signs are that the urine volume is obviously reduced, even no urine exists, and the examination of the body can show the percussion voiced sound of the suprapubic region along with the distending pain of the lower abdomen. If not properly treated in time, it may cause several serious complications such as bladder rupture and even renal failure.

The mode of clinically treating acute urinary retention is generally to insert a catheter and drain urine to solve the urinary retention. Problems often arise. Generally speaking, the more severe the acute urinary retention, the slower the first time urine is drained and the less urine is drained, otherwise the bladder is easily congested and even the blood vessels are ruptured or syncope is easily caused. After the first drainage, the urine is drained again in fifteen to twenty minutes, and three or even four times of bladder urine emptying is known. This greatly increases the workload on the clinician nurse.

In addition, the clinically existing catheter is the most common double-cavity or three-cavity catheter, and the catheter does not have a device or a valve capable of controlling the urine drainage speed, so when the catheter is used for carrying out catheterization on a patient suffering from acute urinary retention, urine can be quickly drained from the bladder, and syncope of the patient can be possibly caused. When the existing catheter conducts urine, once the catheter is inserted in place, the urine can be discharged from the bladder at a very high speed due to the lack of a related control valve device, and the catheter is clamped after 500-800 ml of urine is discharged. However, the discharge speed of urine is too fast, so that the urinary bladder is congested, and even blood vessels are ruptured and coma can be caused sometimes. It is important to control the rate at which urine is discharged. In response to this, it is important that the catheter itself has a controllable means.
