Problems solved by technology

[0004] For this reason, some newly invented leak-proof urinary catheters generally start with the urethral part of the urethra, and some new devices are added to the rear urethral part of the indwelling catheter, such as water bags and air bags. Injection of water (inflation) to the anti-leakage part of the urethra by experience twice to increase the adhesion between the urethral catheter and the urethral mucous membrane to prevent leakage, but this operation is cumbersome, and both intubation and extubation will increase the workload and operation steps, and if the operation It is easy to over-expand the urethra and damage the urethra accidentally, and this design will cause some urine to stay in the cavity between the bladder water sac and the urethral water (air) sac, making it difficult to flow and increasing the chance of infection

Embodiment Construction

[0013] According to the drawings, the present invention is "simple leak-proof urinary sac valve catheter".

[0014] The front end of the latex catheter lumen 1 is matched with the bladder end opening 4 to lead to the bladder, and the back end is matched with the urine bag end opening 6 to connect the urine bag.

[0015] A water bladder 2 is provided at the back end of the bladder end opening 4 of the latex urinary catheter. The water bladder 2 communicates with the water bladder injection port 5 through the cavity 9 between the lumen of the latex urinary catheter and the tube wall.

[0016] The rear top of the latex catheter water bag 2 is provided with a skirt-shaped valve 3, and when the catheter is not in use, the skirt-shaped valve 3 is umbrella-like bonded and contracted with the water bag part 8 to form a whole called water bag, skirt-shaped Valve part 7. After the water bladder 2 is filled with water, the water bladder and the skirt valve portion 7 are expanded to separate th...

Abstract

The invention discloses a simple urine leakage prevention water bag valve urethral catheter, which belongs to a medical instrument. According to the urethral catheter, a circle of skirt-shaped valve is newly and additionally arranged above a common water bag urethral catheter water bag to realize leakage prevention. The skirt-shaped valve is shrunk and attached to the urethral catheter water bag part at a production stage by means of a special process or adhesion action; after the urethral catheter is determined to enter the bladder in use, water is injected from a water injection port of the water bag, and the skirt-shaped valve is expanded along with water injection of the water bag to be opened and be separated from the original water bag; the skirt valve is attached to the neck of the bladder by means of pressure of the water bag and internal pressure of the bladder just like a piece of thin film covering the water outlet; no matter whether the urethral catheter is closely attached to the urethra, the skirt valve has a seepage blocking effect on the neck of the bladder; and even if the bladder of a patient is actively or non-actively (stimulated) shrunk, the valve is more closely pressed around the neck of the bladder when the pressure of the bladder increases, no dead space exists, the seepage of urine around the urethral catheter can be effectively prevented, and reverse infection is prevented. The urethral catheter is easy and convenient to operate; and compared with the conventional urine catheterization, the workload is not increased.

Description

technical field [0001] The invention relates to a medical device, in particular to a water bladder leakage-proof urinary catheter. Background technique [0002] Clinically, when catheterizing patients with urinary retention caused by various reasons and surgery patients or needing to indwell a catheter, the general rubber catheter is often inserted into the urethra first, and then injected from the water injection hole of the back-end water bag after the bladder. Sterile water is fixed by compressing the neck of the bladder after the water bag is inflated. This method is widely used in clinical practice. [0003] However, due to the soft nature of the tube, it is difficult to completely fit around the catheter and the urethra, and the water bladder is flexible and fixed in shape, and it is also difficult to completely fit the bladder neck. And the bladder will often contract actively or inactively (stimulation) to cause urination. At this time, the urine in the patient's bl...
