Description

A kind of external urination guide device for women

technical field

The invention belongs to the field of urination guides and sanitary products, and in particular relates to a female external urination guide.

Background technique

In our modern daily life, with the development of the economy, the time people are not indoors is greatly increased. Instead, it is the time in the vehicle on the road and the time for traveling in other places. During these times, people often encounter urgent urination, A situation that cannot be resolved immediately. Especially female comrades, sometimes they can't urinate in time even at the door of the toilet. This is very common on trains during the Spring Festival travel period, high-speed service areas and toilets in tourist areas. In fact, a small amount of ordinary urine can be completely absorbed in the wild for about a week, and will not cause environmental pollution in the strict sense.

technical problem

Due to the special structure of the excretory opening of women, the cloaca shares the mouth, and the lower edge of the mouth is very low. As a result, women need to open the bottoms to a very low level to expose the lower body, so that the urine guide can be seamlessly connected with the excretion opening and can be drained smoothly; how to It has always been a problem to operate the urination guide in a concealed manner without leaking and completely draining out. Women in normal clothes must expose their lower body if they want to use the urination guide to prevent their underwear from getting wet. The purpose is to better Grasp the urinal guide or urinal so that it fits tightly without leaking. Holding the urinal guide with the palm ring and pressing it is a common operation method for existing products, plus bags and bottles used to hold urine In order to achieve a good docking between the body and the urine guide and completely drain or collect the urine; these reasons make the existing urine guide protrude a lot from the skin, and it takes up too much space to be held by the palm of the hand and is not suitable for use in the crotch of the underwear The narrow space operation is not conducive to concealed use, and the constraints of the lower body must be released to fully expose the lower body to achieve alignment. Most of them are made of soft materials, such as film disposable urine bags, silicone funnels, paper cup cone funnels, etc. , they are very inconvenient to operate, and if there is a slight negligence, urine leakage will result in a very bad user experience. There are also some existing products that can partially solve the above problems, but there are more or less oversized, difficult to carry, high operation requirements, high probability of urine leakage, and inconvenient use by many people, especially when the user is a woman The problem of needing to take off the trousers to expose the lower body remains unresolved, so a better technical solution to the above problems is desired by all.

technical solution

The present invention provides an in vitro urination guide, aiming at solving the problem that existing urination guides are too large in size, not easy to carry, require a high operating space, have a high probability of urine leakage, are inconvenient to use in public places, and have insufficient privacy. Especially the problem that women need to take off their pants to expose their lower body; in order to solve these problems, the present invention has restructured the concept of female use requirements, product functions, and operation methods of the external urination guide. The use requirement is positioned as using in public places without exposing the lower body; the thickness direction of the receiving bucket protruding from the skin is that is, the orthographic projection point of any point on the receiving bucket except the drainage tube joint on the symmetry plane to the contact edge on the symmetry plane The minimum distance of the orthographic projection is reduced as much as possible to facilitate the insertion from the upper opening of the bottom and the user's single palm operation and maximize the operability of the product in the bottom of the narrow triangular area. At the same time, the receiving bucket has a relatively flat shape. The unique shape increases the mechanical stability during the pressing operation; the drainage hole is also designed on the edge of the receiving bucket, so that the receiving bucket has a flat and continuous large back, and then the back of the receiving bucket is ergonomically designed The optimization of science and mechanics makes the receiving bucket have a curved surface on the back of the receiving bucket that can fit the palm of a single palm and a large back pressing area that is easy to press. This design of the receiving bucket makes it possible to Pressing with one finger on the back can stably press the receiving bucket so that the contact edge and the skin can be well pressed; the overall shape design of the receiving bucket is also in accordance with the physiological structure of the triangular area of female users. The rounded triangle is more conducive to the self-guidance of the non-visual operation of the receiving bucket in the bottom, which coincides with the female physiological triangle; the drainage tube with radial support is used and the minimum diameter is optimized and reduced to facilitate the drainage tube Turn down from the thighs of the underwear to enter the leg space of the bottoms, and there is no need to worry about the collapse of the pipeline; the use method of the female urine guide is optimized to put the bucket in place, press it once and press it down with one finger It can be used safely without leakage of urine after being installed and pressed; even by continuing to increase the design of the anti-extrusion structure, it has realized a new function of using it without holding it by pressing once after the receiving bucket is in place, realizing the first time that women can use temporary storage The in vitro urination guide can stand or sit safely to urinate without worrying about leakage of urine; these are all reconstructed in the functions and usages of existing products for the more secret use requirements proposed by the present invention, which is Significantly different from existing products. Since the size of the thickness direction of the protruding skin of the receiving bucket, the shape of the receiving bucket, the size of the containing cavity, the position of the diversion hole, the minimum diameter of the drainage tube and the direction of drainage are all coupled together to form a complex system, the joint influence Whether the urine guide is easy to use, whether the bottom can be put down without leaving traces, whether the urine can be completely drained away in time, whether it is comfortable to use, whether it is suitable as a portable product, etc., the realization of these designs and concepts are all important. It was obtained after countless design revisions and fine-tuning, and behind it was a huge workload and R&D investment. The content of the above invention is obviously not obvious. Due to the multi-factor coupling and the irregularity of the human body curve, there are various combination designs of different parameters. Therefore, the innovation proposed and realized in the concept, function and usage of the present invention is not easy to use accurate technical parameters to restrict the scope of protection. Therefore, the product concept, function and usage that are innovatively designed by the present invention can only be applied for protection as invention claims. After applying the technical solution disclosed in the present invention, women can use it in an emergency without taking off their pants in public, and realize secret urination, which is even easier and more elegant than urinating in the toilet, which greatly relieves people's mental pressure and embarrassment, and increases the number of females. The willingness of comrades to travel has obvious benefits to society.

Explanation: The directions mentioned in the present invention include up, down, front, back, left, right, looking down, and looking up. The definitions all refer to the above-mentioned directions of the user when the receiving bucket is in the use position.

Obviously, the described embodiments are Some, but not all, embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The invention discloses an external urination guide for women. The external urination guide can be put into a suitable position in the user's bottoms without taking off the trousers. The function of collecting, draining, and discharging the user's urine to the outside world.

For the convenience of expression, in the schematic diagram of the present invention, the wall of the drainage tube is represented by a single line, the section of the human body is not hatched, and the bottoms such as underwear and outer pants are represented by dotted lines. In the views of different view relationships, individual parts will be removed. One explanation; in all schematic diagrams, there are two positions and angles of the receiving bucket, which are the position and angle of correct use and the position and angle of manufacture.

Fig. 1 is a schematic diagram of a receiving bucket according to the first embodiment disclosed by the present invention. In the scheme of Fig. 1, the receiving bucket [11] has a contact edge [111] and an accommodating cavity [112], and [12] is a receiving bucket [11] The symmetry plane of the bucket, the receiving bucket is a part with supporting strength, which can keep the contact edge of the urine guide outside the body in a sufficiently stable shape during use; the volume of the accommodation cavity [112] is not less than 10ML, and the volume of the accommodation cavity Existence, so that the impact force of the urine with pressure and flow rate in the process of converging is eliminated, forming a stable stock of urine, on the one hand, it forms a pressurized discharge, on the other hand, it weakens the poor discharge caused by the liquid impulse . The receiving bucket has a drainage hole [115], and the receiving bucket also has a drainage pipe connector [116].

Fig. 2 is a schematic diagram of the use of the first embodiment disclosed by the present invention, including three views, a partially enlarged view, all three views are schematic views, there is no strict view projection relationship, and the view on the right is a cross-sectional view; drainage tube [22] The upper mouthpiece [221] of receiving the Sheng bucket [21] is connected watertightly by the drainage pipe connector [216] on the Sheng bucket, and the drainage pipe and the drainage hole [215] of receiving the Sheng bucket are communicated. The drainage tube [22] is a tube with radial support. Under normal use, no matter how it is bent, it can ensure the middle passage. The drainage tube needs at least one turn from the direction of the underpants to the selected discharge port [28] . The female physiological triangle [25] is surrounded by the thigh and lower abdomen, including the [26] urethral opening, [27] the vaginal opening, and [29] the anus. The first embodiment of the present invention is to use the back pressing area [218] of the hard receiving bucket to make the contact form a depression [188] along the skin rich in soft tissue, and to form the skin and subcutaneous soft tissue inside the receiving bucket. The temporary bulge [23] form is used to prevent urine leakage, the urine [231] flows down along the surface of the temporary bulge, and the contact edge is kept dry to prevent leakage of urine along the contact edge caused by capillary adsorption; when using this in vitro urine guide During the process from the beginning of urinating to the end of urination, the simplest operation that can be used without leakage of urine is to connect the pressing area of the bucket with one finger through the bottom.

Figure 3 is a schematic view of the second embodiment of the present invention. The second embodiment is a female-specific external urination guide with a prolapse-proof structure. Hold force, to balance because of pressing the bucket tightly, make the contact edge fall into the excretion port with rich subcutaneous soft tissue around the excretion port, the skin soft tissue will come out of the rebound force of the contact edge, so that the present invention can realize the pressing once and then release the pressing force The functional intention is that the hand can also urinate without leaking. Fig. 3 comprises two views, and a partial enlargement figure, and two views are schematic diagrams, and there is no strict view projection relationship, and the view on the right is a sectional view; The receiving bucket [31] and the drainage tube [22] are watertightly connected, when the connecting After the Sheng bucket [31] is pressed in place, use the thigh to clamp the receiving bucket, and the anti-prolapse structure [319] on the receiving bucket forms a depression in the skin and soft tissue [588] on the thigh, so that even if the pressing hand is removed, the It can keep the temporary bulging [33] shape of the skin in the receiving bucket without leakage of urine. Equally, the drainage tube [22] needs at least one turn [28] from the direction in the underpants to the direction of the selected outlet; During the process, the simplest operation that can be used without leakage of urine is to clamp the receiving bucket with the thigh without any support operation.

As shown in Figure 4, it is a schematic diagram of a large oblique angle anti-extrusion structure, [41] is a receiving bucket, [411] is a contact edge, when the anti-extrusion structure with a large oblique angle [45] is adopted within the clamping range of the thigh The design structure diagram of the receiving bucket and the schematic diagram of the anti-stripping force [46] obtained during use. The oblique angle mentioned here in the present invention means that when the receiving bucket is in the use position, in any vertical left and right direction sectional plane, the shape section line of the receiving bucket is in contact with the tangent and the connecting point [47] along the joint. The included angle of Sheng bucket symmetry plane [48]; The large oblique angle refers to the oblique angle value that adopts greater than the commonly used demoulding angle number in the clamping range of the thigh root for realizing the anti-prolapse function intention of the present invention, and commonly used demoulding The number of angles is generally less than 10 degrees, and a large bevel value can significantly increase the upward component of the rebound anti-extrusion force [46] of the sunken skin. This upward component can balance the prolapse rebound force on the contact edge; The depth [49] of the receiving bucket of the same width is greatly reduced, so that the depth of the accumulated liquid level decreases, the pressure of urination is reduced, and the caliber of the drainage hole and drainage tube required to achieve the same urination flow rate must be increased, so large Bevel design is not just as simple as increasing the draft angle.

The flanging in the present invention refers to the flanging with wall thickness extending from the contact along the curved surface [57] to the outside of the receiving bucket. The edge [55] can also be the flanging from the contact along the curved surface toward the direction away from the skin to the outside of the receiving bucket. This kind of flanging with a thick wall is supported by the strong receiving bucket [51]. When the thigh root When the receiving bucket is clamped, the flanging falls into the skin soft tissue depression [588] of the thigh root, and the rebound anti-prolapse force given to the flanging by the thigh root soft tissue can balance the prolapse rebound force received by the contact edge [511]. It should be noted that when a flange is added to the contact edge, according to the definition of the contact edge in the present invention, the surface where the flange contacts the body becomes a part of the new contact edge. As shown in Figure 5, it is a schematic diagram of the anti-extrusion structure of the flange along the contact along the curved surface. When the receiving bucket has the anti-extrusion structure shown in Figure 5, it can obtain the rebound anti-exit force under the clamp of the thigh [56 ].

As shown in Figure 6, it is a schematic diagram of the combined use of two kinds of flanging anti-extrusion structures. First, the flanging along the direction of the contact along the curved surface [55] is used, and then the flanging [65] is used from the direction of the contact along the curved surface away from the user's skin. The combined anti-extrusion structure can also obtain the rebound anti-extrusion force from the clamping force of the thigh [66]. Compared with the flanging structure in Fig. 5, this structure has a more comfortable user experience, [61] is the receiving bucket, and [611] is the contact edge.

As shown in Figure 7, it is a schematic diagram of an anti-falling out structure with a damping body added to the receiving bucket.
