Description

Technical Field

[0001] The present invention relates to a human urination auxiliary device, and more particularly to a urinator which is easy to install. Background Art

[0002] For men who are bedridden for a long time or have urinary incontinence, how to cope with multiple urinations every day becomes a troublesome problem.

[0003] The existing treatment methods usually include wearing diapers or wearing a urinal. However, wearing diapers not only easily produces a wet, stuffy, and hot feeling, but also urine contacts the skin for a long time, which is also easy to cause skin allergies or other diseases. Wearing a urinal can solve the urination problem and avoid skin contact with urine. However, as disclosed in the urinary device of Taiwan Patent Certificate No. I706775 and Patent No. M581463, U.S. Patent No. 5478334 and Patent No. 5645541 and Japanese Patent Laid-Open No. 9-94262, the urinary device structure disclosed in the above patents mainly includes a urine catheter cover and a leak-proof sleeve, the urine catheter cover has an internal urine catheter space, an inlet connecting the urine catheter space to the outside, and an outlet connecting the urine catheter space to the outside, the outlet is connected to a urine catheter, and the end of the urine catheter is connected to a urine bag, the outer periphery of the leak-proof sleeve is sleeved and combined with the outer part of the urine catheter cover located at the inlet, and the central position of the leak-proof sleeve has a sleeve opening, so that the front end (glans) of the male reproductive organ (penis) can be inserted into the urine catheter space through the sleeve opening, and the periphery of the sleeve opening is sleeved on the outer periphery of the body of the penis. Thus, when the human body urinates, urine will be discharged into the catheterization space of the catheter cover and flow into the urine bag through the outlet and the catheter for collection. Since the periphery of the leak-proof sleeve is sheathed on the body of the penis, urine can also be prevented from leaking.

[0004] However, in the above-mentioned conventional urinator, since the leak-proof sleeve must be wrapped around the outer circumference of the body of the penis, the opening of the leak-proof sleeve is designed to be small. Although the leak-proof sleeve is elastic, when the glans of the penis is passed through the opening and the outer circumference of the opening is wrapped around the appropriate outer circumference of the body, the leak-proof sleeve still needs to be adjusted by moving left and right, forward and backward, etc., making the entire installation process quite inconvenient and time-consuming.

[0005] Moreover, after the urinator is installed on the penis, the human body will still move and change its posture, thus pulling the leak-proof sleeve, and the leak-proof sleeve does not provide sufficient length margin, causing the human body to feel uncomfortable. Summary of the invention

[0006] In view of this, in order to improve the prior art, the conventional urinary device has the problem of being difficult to install when worn on the male reproductive organ.

[0007] The object of the present invention is to provide a urinary device that is easy to install, which can greatly improve the convenience of installation and wearing and reduce the time required for wearing.

[0054] In order to provide a further understanding and recognition of the features and characteristics of the present invention, the following embodiments are listed and described with reference to the accompanying drawings:

[0055] See also Figures 1 to 15 , a conveniently installed urinary device 100 provided by a preferred embodiment of the present invention, comprises a urine guide cover 10, a leak-proof sleeve 20, an outer support ring 30, a urine catheter 40 and a urine bag 50, wherein:

[0056] See also Figures 1 to 4 The urinary catheter cover 10 is made in one piece and is a roughly hemispherical cover. The urinary catheter cover 10 has a hemispherical urinary catheter main shell 11, an introduction part 12 protruding from one side of the urinary catheter main shell 11, and an outlet part 13 protruding from the bottom side of the urinary catheter main shell 11. The urinary catheter main shell 11 has a urinary catheter space 111, and the wall surface of the urinary catheter space 111 is arc-shaped. The urinary catheter main shell 11 is formed with a convex stopper 112 on the upper and lower ends of the end surface adjacent to the introduction part 12. Each convex stopper 112 has a block 113 extending outwardly and an insertion gap 114 between the block 113 and the end surface of the urinary catheter main shell 11. A plurality of convex tubes 115 are extended inwardly and downwardly on the inner wall surface of the top of the urinary catheter main shell 11. Each convex tube 115 An air hole 116 is formed inside the urinary catheter space 111 to connect with the outside world. The outer diameter of the introduction part 12 is smaller than the outer diameter of the urinary catheter main shell 11. An introduction hole 121 is formed in the center of the introduction part 12 to connect with the urinary catheter space 111 to the outside world. A sleeve ring groove 122 is formed on the outer peripheral surface of the introduction part 12. A lead-out hole 131 is formed in the center of the lead-out part 13 to connect with the urinary catheter space 111 to the outside world. At least one diversion rib 132 extends from the hole wall of the lead-out hole 131. The introduction part 12 and the lead-out part 13 form a mutually perpendicular angle, that is, when the introduction part 12 is in a horizontal state, the lead-out part 13 is in a vertical downward state.

[0057] See also Figures 1 to 4The anti-leakage sleeve 20 has a collar 21 located at the periphery, a sleeve opening 22 located at the center, and a sleeve membrane 23 connected between the collar 21 and the sleeve opening 22. When no external force is applied, the inner diameter of the collar 21 is larger than the inner diameter of the sleeve opening 22. The sleeve membrane 23 is elastic and is made of a waterproof material with a very large elastic expansion rate, such as natural latex rubber, natural latex rubber with additives, or water-based polyurethane. The materials all have a very large elastic expansion rate and waterproof properties. The ideal thickness of the anti-leakage sleeve 20 is 0.04 mm, but it can be thinner or thicker as needed. The sleeve membrane 23 is a thin film annular body extending in an arc shape. The collar 21 of the anti-leakage sleeve 20 is placed in the sleeve ring groove 122 of the urinary catheter 10, so that the sleeve opening 22 is connected to the introduction hole 121.

[0058] See also Figures 1 to 4 and Fig.15 The outer support ring 30 is a ring body with a through hole 301 passing through both ends. Its bottom edge is formed as a radially protruding annular flange 302. A clamping portion 31 is provided on the inner peripheral wall surface corresponding to the convex stop portion 112. Each clamping portion 31 has a recessed embedded groove 311 and a stopper 312 which are all L-shaped. The embedded groove 311 has a first groove area 313 extending axially from one end of the outer support ring 30 along the inner peripheral wall surface and a second groove area 315 extending radially from the end of the first groove area 313. The stopper 312 is located in the area of ​​the same side where the first groove area 313 and the second groove area 315 are adjacent to each other. Two spaced notches 32 are formed on the outer peripheral surface 34 of the outer support ring 30. The outer peripheral surface 34 of the outer support ring 30 is also formed with a plurality of rough lines 33 on the outer peripheral surface 34 where the notches 32 are not provided. The outer support ring 30 is looped on the introduction portion 12 of the urinary catheter cover 10, so that the outer support ring 30 and the urinary catheter cover 10 can be quickly and detachably combined by means of the convex stop portion 112 and the engaging portion 31. The inner circumference of the outer support ring 30 is pressed against the ring 21 of the leak-proof sleeve 20 to prevent the leak-proof sleeve 20 from separating from the urinary catheter cover 10 by itself, and the sleeve membrane 23 can pass through the through hole of the outer support ring 30 and be located on the outside. Among them, the combination method between the engaging portion 31 of the outer support ring 30 and the convex stop portion 112 of the urinary catheter cover 10 is briefly described. First, when the combination is to be combined, the inner peripheral wall surface of the outer support ring 30 is firstly encircled on the outer periphery of the introduction portion 12 of the urinary catheter cover 10, and the block 113 of the convex stop portion 112 on the urinary catheter cover 10 is axially extended into the first groove area 313 of the engaging portion 31 of the outer support ring 30 until it is completely inserted into the first groove area 313, and then the block 113 is rotated radially into the second groove area 315, so that the stopper 312 of the engaging portion 31 is exactly located in the snap-in gap 114 of the convex stop portion 112 (such as Figure 3As shown in FIG. 1 ), the stopper 312 of the outer support ring 30 and the block 113 of the urinary catheter cover 10 are locked against each other and cannot be separated, thereby achieving the effect of rapid combination. When the outer support ring 30 is to be quickly detached, the reverse operation can be performed.

[0059] See also Figures 1 to 4 The urinary catheter 40 is connected with the outlet portion 13 of the urinary catheter cover 10 at one end thereof, thereby communicating with the introduction hole 131 .

[0060] See also Figure 12 to Figure 14 The urine bag 50 is connected to the other end of the urinary catheter 40 , thereby communicating with the urinary catheter 40 .

[0061] Therefore, the above is an introduction to the components of a urinary device 100 that is easy to install according to a preferred embodiment of the present invention. Next, its usage features are introduced as follows:

[0062] First, when the user wants to use the present invention, he first inserts the thumb and index finger of both hands into the sleeve opening 22 of the leak-proof sleeve 20, and then pulls the periphery of the sleeve opening 22 outward to expand and turn it outward, so that the sleeve film 23 covers the outer peripheral surface 34 of the outer support ring 30 (such as Figure 5 As shown in FIG. 1 ), the introduction hole 121 of the urinary catheter cover 10 is completely exposed. Then, the glans 91 at the front end of the user's penis 90 (genitalia) can be inserted into the urinary catheter space 111 from the introduction hole 121 without any hindrance (as shown in FIG. 1 ). Figure 6 As shown), the sleeve film 23 covering any notch 32 of the outer support ring 30 can then be moved by finger 99 (as shown in FIG. Figure 7 As shown), the membrane 23 of the anti-leakage sleeve 20 is turned inward, so that the membrane 23 of the anti-leakage sleeve 20 is no longer covered on the outer peripheral surface 34 of the outer support ring 30, but is attached to the body 92 of the middle section of the penis 90 by the peripheral edge of the sleeve opening 22 (as shown in FIG. Figure 8 As shown in the figure, the procedure of combining the present invention with the penis 90 is completed, and then the catheter 40 is fixed to the user's thigh 94 using an elastic band 93, and the urine bag 50 is fixed to other objects (such as a chair, a bed, a wheelchair, a calf, etc.) using another elastic band 93, thereby completing the complete installation procedure of the present invention.

[0063] Therefore, by utilizing the structure of the present invention, the anti-leakage sleeve 20 that may cause installation obstacles can be turned outward first and elastically expanded to cover the outer support ring 30, so that the glans 91 at the front end of the user's penis 90 can be inserted into the urinary catheterization space 111 of the urinary catheter cover 10 without any obstacles. After the glans 91 is inserted into the urinary catheterization space 111, the anti-leakage sleeve 20 is turned inward to restore elasticity and be connected to the outer periphery of the body 92 of the penis 90, thereby greatly improving the convenience of installation and reducing the time required for installation. For the user or the person who takes care of him, it can be much easier to reduce the disgust caused by long-term use.

[0064] Furthermore, since the membrane 23 of the anti-leakage sleeve 20 of the present invention is not only very elastic, but also a thin film ring extending in an arc shape, no matter the user's penis 90 moves upward (such as Fig. 9 ), down (as shown), Fig.10 ), left or right (not shown), or backward (as shown) Fig.11 As shown in the figure, there is enough elastic margin to follow the deformation state of the penis 90 such as stretching and compression to avoid discomfort caused by the penis 90 being pulled, that is, the comfort of the present invention can be improved.

[0065] In addition, whether the user is sitting (such as Fig.12 As shown), standing position (as shown Fig.13 as shown) or lying position (as Fig.14 ), the present invention will not cause difficulty in changing posture, that is, the present invention can be used in the case of user activities, so as to improve the applicability of the present invention. In particular, the user can wear underwear or adult diapers with holes for the catheter to pass through, and the underwear or adult diapers can not only cover the catheter cover of the present invention to reduce the possibility of shaking and moving, but also achieve the effect of improving comfort.

[0066] Again, if Fig.12 As shown, 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 movement of the user, the elastic band 93 must be fixed on the thigh and calf first, and the outer side of the elastic band 93 has a Velcro surface and a hook surface that can be glued and fixed, and the urine bag 50 also has a Velcro surface with a hook surface and a Velcro surface, so that the urine bag can be conveniently combined with the elastic band 93 on the calf, and the Velcro on the elastic band 93 can be used for quick detachment and combination.

[0067] Secondly, when the user is in a lying position (such as Fig.14 In the case of (as shown in the figure), the urine bag 50 can be replaced with a collection bucket 60 to facilitate emptying it into the toilet at any time.

[0068] In the present invention, the wall surface of the urinary catheter space 111 is arc-shaped, and the inner wall surface of the outlet hole 131 of the urinary catheter cover 10 is provided with a diversion rib 132 (such as Figure 4 As shown in the figure, when the urine of the user is discharged into the urinary catheter space 111, it will smoothly flow to the outlet hole 131 by utilizing the curved wall surface of the urinary catheter space 111, and then flow out to the urinary catheter 40 and to the urine bag 50 for collection after being diverted by the diverter ribs 132. The urine can be smoothly diverted by utilizing the curved wall surface of the urinary catheter space 111 and the diverter ribs 132, thereby avoiding the occurrence of urine accumulation and discharge problems.

[0069] Furthermore, since the present invention has a plurality of air holes 116 connected to the outside in the urine-conducting space 111, the urine-conducting space 111 can be prevented from forming a vacuum state, that is, the air pressure in the urine-conducting space 111 can be kept in the same equilibrium state as the air pressure in the outside, so as to avoid the situation where the urine in the urine-conducting space 111 cannot be discharged due to the pressure difference between the inside and the outside, that is, the effect of improving the smoothness of urination can be achieved. Next, since the convex tube 115 in the present invention extends downward, if the user sleeps on his side, the entire urinator will lean to one side, and the convex tube 115 will be in a horizontal state at this time. If the user urinates at this time, the urine level in the urine-conducting space 111 must be higher than the convex tube 115 before the urine will flow out from the air holes 116. However, generally speaking, the urine discharged during sleep will not accumulate to a height higher than the convex tube 115, so the design of the convex tube 115 can prevent the urine from flowing out from the air holes 116.

[0070] In addition, the radially protruding annular flange 302 at the bottom edge of the outer support ring 30 can prevent the everted membrane 23 from entering the gap between the urinary catheter cover 10 and the outer support ring 30 and getting stuck, so as to ensure that the user can use the fingers 99 to push the everted membrane 23 back to its original state.

[0071] Finally, after the present invention has been used for a period of time, the user's penis 90 can be pulled out of the leak-proof sleeve 20, and the outer support ring 30 can be detached, and the leak-proof sleeve 20 can be replaced with a new one, and then the outer support ring 30 can be screwed on again. In this way, the cleanliness of the present invention can be maintained, and only the consumables of the leak-proof sleeve 20 need to be replaced, thereby reducing the long-term cost.

[0072] The above disclosure is only the preferred embodiment provided by the present invention and is not intended to limit the scope of implementation of the present invention. All equivalent changes made by relevant technical personnel in the technical field based on the present invention should fall within the scope covered by the present invention.
