Description

Three-cavity catheter for bladder irrigation

Technical Field

The utility model relates to an appliance for connecting a flexible tube and a rigid auxiliary device, in particular to a three-cavity catheter for bladder irrigation.

Background

Urinary catheters are one of the most commonly used medical devices in urology and have the function of quickly emptying the bladder of a patient and reducing the associated complications caused by urine retention. A common catheter is generally a double-cavity catheter, and when a patient with a filled bladder or a bleeding bladder is met, the three-cavity catheter is used for communicating with an irrigation device. But a plurality of defects are exposed in the actual clinical work, which brings trouble to the work of doctors. Most patients with bladder stuffiness and bladder hemorrhage are in critical conditions, and a large amount of blood clots in the bladder of the patients form blocked ureters, so that urine drainage is not smooth, and acute urine retention is caused. If not handled in a timely manner, this can result in damage to the patient's renal function on the one hand and even bladder rupture on the other. While conventional three-lumen catheters have no means of connection to the irrigation device. In order to flush the clot blocking the ureter from the bladder as quickly as possible, the clinician can only use syringe aspiration to increase the pressure. However, since there is no corresponding connection device, the doctor can only pinch the end of the ureter and connect the injector nipple with the ureter by one hand for suction. At this time, the hand holding the ureter needs to be tightened all the time, otherwise the liquid pumped in or pumped out can splash along the orifice and overflow, and on the other hand, the blocked blood clot cannot be pumped out of the bladder due to insufficient pressure. A small amount of blood clots can persist in a short time, but the long-time operation can cause the upper limbs of medical staff to be weak, and further the situation of incomplete suction or urine leakage and the like can occur. In addition, after the three-cavity urinary catheter is washed, the side tube is communicated with the bladder, if the side tube is not blocked, part of urine overflows along the side tube, and at the moment, a doctor routinely needs to block the side tube by using a clamp or a blocking object such as a needle head cap and the like. In the later recovery process of patients, urine leakage is caused by the conditions of falling off and the like because the needle head cap and the ureter mouth are poor in sealing fit.

The catheter is a flexible tube made of rubber, silica gel or plastic, can be inserted into the bladder through the urethra so as to guide urine out, after the double-cavity catheter is inserted into the bladder, an air bag is arranged at the end close to the catheter end to fix the catheter in the bladder, so that the catheter is not easy to fall off, and the catheter is connected with a urine bag through a drainage tube to collect urine.

The common three-cavity catheter comprises an air bag communicated with an air injection pipe orifice, a flushing hole communicated with a flushing pipe orifice, and a drainage hole communicated with a drainage pipe orifice, wherein the urine guide pipe orifice and the flushing pipe orifice are communicated with a drainage pipe through a reducing connecting pipe.

In addition, the flushing pipeline is easy to be blocked by sundries such as large blood clots in the bladder, and the flushing drainage is not smooth.
