Description

Urine receptacle easy to assemble

Technical Field

The present invention relates to a human urination assisting device, and more particularly to a urination apparatus which is convenient to install.

Background

For men who are bedridden for a long period of time or who suffer from urinary incontinence, how to deal with urination multiple times per day becomes a troublesome problem.

In the conventional disposal methods, two methods, namely wearing a diaper or wearing a urination apparatus, are generally adopted. However, when wearing the diaper, not only the diaper is prone to generate damp, stuffy and hot feeling, but also the urine is prone to cause skin allergy or other pathological changes after being contacted with the skin for a long time, and the mode of wearing the diaper can solve the problem of urination and avoid the contact between the skin and the urine. However, as disclosed in taiwan patent document nos. I706775 and M581463, U.S. patent nos. 5478334 and 5645541 and japanese patent application laid-open No. 9-94262, the urinary drainage structure disclosed in each of these patent cases mainly includes a urinary catheter cover and a leakage-stopping cover, the urinary catheter cover has a urinary catheter space inside, an inlet port communicating the urinary catheter space to the outside, and an outlet port communicating the urinary catheter space to the outside, the outlet port is connected to a urinary catheter, the end of the urinary catheter is further connected to a urinary bag, the outer periphery of the leakage-stopping cover is connected to the outer periphery of the urinary catheter cover, and the central position of the leakage-stopping cover has a cuff for the front end (glans penis) of the male genital (penis) to penetrate into the urinary catheter space and to be bound around the periphery of the cuff of the penis. Therefore, when a human body urinates, the urine is discharged into the urethral catheterization space of the urethral catheterization cover and flows into the urine bag through the urethral catheterization opening and the urethral catheter to be collected, and the circumference of the opening of the leakage-stopping sleeve is sleeved on the body part of the penis, so that the urine can be prevented from leaking.

However, in the above-mentioned conventional urination apparatus, since the leakage stopping cover must be fitted around the outer circumference of the body of the penis, the opening of the leakage stopping cover is designed to be small, and although the leakage stopping cover has elasticity, the leakage stopping cover must be adjusted to move left and right, move forward and backward, etc. during the process of passing the glans of the front end of the penis through the opening and fitting the outer circumference of the opening around the proper position of the body, so that the whole installation process is inconvenient and time-consuming.

Referring to fig. 12-14, the urine bag 50 is connected to the other end of the urinary catheter 40, and is in communication with the urinary catheter 40.

Therefore, the above description is provided for the components of the urine drainage device 100 which is easy to install according to the preferred embodiment of the present invention, and the following description is provided for the features of use:

firstly, when the user wants to use the present invention, the thumb and the forefinger of both hands are inserted into the cuff 22 of the anti-leakage restraining sleeve 20, and then the peripheral edge of the cuff 22 is pulled outward and turned outward, so that the cover film 23 covers the outer peripheral surface 34 of the external supporting ring 30 (as shown in fig. 5), and the introduction hole 121 of the urethral catheterization cover 10 is completely exposed. Then, the glans 91 at the front end of the penis 90 (genitals) of the user can be inserted into the urethral catheterization space 111 through the introduction hole 121 without hindrance (as shown in fig. 6), and then the sleeve 23 covering any notch 32 of the external support ring 30 can be pulled by the fingers 99 (as shown in fig. 7), and the sleeve 23 of the anti-leak sheath 20 is turned inside out, so that the sleeve 23 of the anti-leak sheath 20 is no longer covered on the outer peripheral surface 34 of the external support ring 30, and the peripheral edge of the cuff 22 is attached to the body 92 at the middle section of the penis 90 (as shown in fig. 8), thereby completing the procedure of combining the present invention with the penis 90, and then the urinary catheter 40 is fixed on the thigh 94 of the user by the elastic band 93, and the urine bag 50 is fixed on other objects (such as a chair, a bed, a calf, etc.) by the other elastic band 93, thereby completing the complete installation procedure of the wheelchair of the present invention.

Therefore, with the structure of the present invention, the leakage-stopping restraining sleeve 20 which will cause the installation obstruction can be firstly turned outwards to elastically expand and cover on the external supporting ring 30, so that the glans 91 at the front end of the penis 90 of the user can extend into the urethral catheterization space 111 of the urethral catheterization hood 10 without obstruction, and after the glans 91 extends into the urethral catheterization space 111, the leakage-stopping restraining sleeve 20 is turned inwards to recover to be elastically restrained on the periphery of the body 92 of the penis 90, thereby greatly improving the convenience in installation and reducing the time required for installation. The utility model can be used for users or people beside the users to reduce the aversion feeling caused by long-term use.

Furthermore, since the covering film 23 of the leakage-stopping collar 20 of the present invention is a circular-arc-shaped film ring-shaped body besides having elasticity, no matter the penis 90 of the user moves up (as shown in fig. 9), down (as shown in fig. 10), left or right (not shown) or backward (as shown in fig. 11), there is enough elasticity margin to follow the deformation state of the penis 90 such as stretching and compressing, so as to avoid the discomfort caused by pulling the penis 90, and thus the comfort of the present invention can be enhanced.

In addition, no matter the user is in a sitting posture (as shown in fig. 12), a standing posture (as shown in fig. 13) or a lying posture (as shown in fig. 14), the invention does not cause difficulty in changing the posture, namely, the invention can be used under the condition that the user is active, so that the applicability of the invention is improved. In particular, the user can wear the underpants or the adult diaper with the hole for the catheter to pass through, and the underpants or the adult diaper can be covered outside the urethral catheterization cover of the invention, so as to reduce the possibility of shaking and moving and further achieve the effect of improving the comfort.

As shown in fig. 12, when the user wears the present invention and wants to go out, in order to prevent the urinary catheter 40 from interfering with the normal actions of the user, the elastic belt 93 must be fixed on the thigh and the calf, the outer side of the elastic belt 93 has a hook surface and a hook surface to which the hook tape can be adhered and fixed, and the urine bag 50 also has a hook tape with a hook surface and a hook surface, so that the urine bag can be conveniently combined with the elastic belt 93 of the calf, and can be quickly detached and combined by the hook tape on the elastic belt 93.

Secondly, in the case where the user is lying (as shown in fig. 14), the urine bag 50 can be replaced with a collection bucket 60 so as to be conveniently poured into the toilet at any time.

In the present invention, the wall surface of the urine guiding space 111 is curved, and the diversion rib 132 is disposed on the inner wall surface of the outlet hole 131 of the urine guiding cover 10 (as shown in fig. 4), so that when the urine of the user is discharged into the urine guiding space 111, the urine flows smoothly to the outlet hole 131 by the curved wall surface of the urine guiding space 111, is diverted by the diversion rib 132, and then flows out to the urine guiding tube 40 and to the urine bag 50 for collection, so that the urine is smoothly diverted by the curved wall surface of the urine guiding space 111 and the diversion rib 132, thereby avoiding the occurrence of urine accumulation and unsmooth discharge.

Furthermore, since the plurality of air holes 116 communicated with the outside are arranged in the urethral catheterization space 111, the urethral catheterization space 111 can be prevented from forming a vacuum state, namely, the air pressure in the urethral catheterization space 111 and the air pressure outside are kept in the same balanced state, so that the condition that the urine in the urethral space 111 cannot be discharged due to the pressure difference between the inside and the outside is avoided, and the effect of improving the smoothness of urination can be achieved. Then, since the protruding tube 115 extends downward in the present invention, if the user sleeps on his side, the whole urinal will lean to one side, and the protruding tube 115 is horizontal, so that the user can urinate at that time, and the urine in the urine guiding space 111 will flow out from the air hole 116 only when the water level of the urine must be higher than the protruding tube 115, but generally speaking, the urine discharged during sleeping will not accumulate to a height higher than the protruding tube 115, so the urine can be prevented from flowing out from the air hole 116 by the design of the protruding tube 115.

In addition, the ring flange 302 protruding radially from the bottom end of the external supporting ring 30 can prevent the outward-turned cover film 23 from entering into the gap between the catheter cover 10 and the external supporting ring 30 and being locked, so as to ensure that the user can use the fingers 99 to pull the outward-turned cover film 23 back to the original state.

Finally, after the present invention is used for a period of time, the penis 90 of the user can be pulled out of the leakage-stopping collar 20, the external supporting ring 30 can be detached, the leakage-stopping collar 20 can be replaced by a new product, and the external supporting ring 30 can be screwed on again, so that the cleanliness of the present invention can be maintained, and only the consumable of the leakage-stopping collar 20 needs to be replaced, thereby reducing the cost required for a long time.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, so that equivalent variations of the present invention will be apparent to those skilled in the art.
