Description

[Technical Field]

[0001] The present invention relates to a urine storage container that is closed with a closure, and more particularly to a urine storage container that is worn directly on the penis to store excreted urine. [Background technology]

[0002] Conventionally, known urine storage containers that are directly attached to the human body include a highly extensible urine storage container (see Patent Document 1) in which a storage section for storing urine, an attachment section, a separation section, and a backflow prevention structure formed on the attachment section to prevent urine backflow are all formed integrally from a material having low hardness and high extensibility, and a urine storage container in which a urine storage section for storing urine, an attachment section, a discharge section, a glans head storage section, and a check valve section formed on the glans head storage section to prevent urine backflow are all formed integrally from a material having low hardness and high extensibility, in which the check valve is closed by the internal pressure of the urine storage section (see Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-123999 [Patent Document 2] Patent No. 7408199 Summary of the Invention [Problem to be solved by the invention]

[0004] However, among these conventional urine storage containers, the one described in Patent Document 1 has the problem that it only stores the stored urine but cannot discharge it. In addition, the inventors have newly discovered that the one described in Patent Document 2 has a risk of the stored urine flowing backward when the check valve opens due to the expansion and deformation of the main body caused by the insertion of the penis, and the amount of urine excreted is small and the internal pressure of the urine storage section is low.

[0005] Therefore, the present invention seeks to solve the problems of the prior art, namely, the object of the present invention is to provide a urine storage container that reliably closes a check valve when attached, thereby reliably preventing backflow of stored urine even when the amount of urination is small and the internal pressure of the urine storage section is low. [Means for solving the problem]

[0006] The invention of claim 1 is a urine storage container comprising a tubular attachment section having an insertion opening for inserting the penis, a tubular glans housing section that is connected to the attachment section and is thinner than the attachment section, a tubular urine storage section that is connected to the glans housing section and stores urine, a tubular discharge section that is connected to the urine storage section and has an outlet opening for discharging the urine, and a check valve section that is formed in the glans housing section and prevents the backflow of the urine, all of which are formed integrally from a biocompatible resin having low hardness and high extensibility, wherein the check valve section has three valve membranes that are formed in a tongue shape toward the inside of the urine storage section, and at least the central portions of the three valve membranes are separated from each other to form a valve opening, thereby solving the above-mentioned problem.

[0007] The invention of claim 2 solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1, arranging the valve portion in a three-fold rotational symmetry with the longitudinal center line of the glans accommodating portion as the rotation axis.

[0008] The invention of claim 3 solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1 or claim 2, having the valve portion connected to the glans accommodating portion at the fixed end portion and the side edge portion.

[0009] The invention of claim 4 further solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1 or claim 2, forming the thickness dimension of the side edge portion of the valve portion larger than the thickness dimension of the central portion.

[0010] The invention of claim 5 further solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1 or claim 2, forming the thickness dimension of the fixed end portion of the valve membrane portion to be larger than the thickness dimension of the free end portion.

[0011] The invention of claim 6 solves the above-mentioned problem by, in addition to the configuration of the invention of claim 1 or claim 2, forming the valve opening into a three-pointed star shape, in that the valve portion has two abutment surface portions that are arranged from the side edge portions to the central portion and are bent and connected at the central portion to form an abutment angle portion. [Effects of the Invention]

[0012] The urine storage container of the invention according to claim 1 comprises a tubular attachment section having an insertion opening for inserting the penis, a tubular glans housing section communicating with the attachment section, a tubular urine storage section communicating with the glans housing section for storing urine, a tubular discharge section having an outlet opening communicating with the urine storage section for discharging the urine, and a check valve formed in the glans housing section for preventing the backflow of urine, all of which are integrally formed from a biocompatible resin having low hardness and high extensibility. This not only enables the container to store urine without interfering with the forward flow of urine, but also provides the following effects specific to the invention of the present application due to the following configuration specific to the invention of the present application.

[0013] Because the glans accommodating portion is thinner than the attachment portion, when in use, simply by attaching it to the penis, the glans accommodating portion expands significantly, creating an inclination angle in the glans accommodating tube portion. In addition, the check valve portion has three valve membrane portions formed in a tongue-like shape toward the inside of the urine accommodating portion, and at least the central portions of the three valve membrane portions are separated from each other to form a valve opening. Therefore, when the urine storage container is attached to the penis in use, an inclination occurs in the glans accommodating tube portion, and the valve membrane portions collapse inward and deform while coming into contact with each other, automatically closing the valve opening. This ensures that backflow of urine caused by the opening of the valve opening is prevented even when the amount of urine excreted is small and the internal pressure of the urine storage portion is low.

[0014] According to the urine storage container of the invention of claim 2, in addition to the effects achieved by the invention of claim 1, the valve membrane portions are arranged with three-fold rotational symmetry around the longitudinal center line of the glans accommodating portion as the rotation axis. Therefore, even if the inclination angle of the glans accommodating tube portion due to the expansion of the glans accommodating portion when the penis is inserted into the urine storage container becomes uneven due to the asymmetrical shape of the glans, the three valve membrane portions arranged with three-fold rotational symmetry will collapse inward at each angle from three directions to close the valve opening, and will work together to close the valve opening while flexibly deforming in a complementary manner, thereby reliably preventing urine backflow regardless of the insertion angle of the penis around the axis of rotation that is the center line of the glans accommodating portion.

[0015] According to the urine storage container of the invention of claim 3, in addition to the effects of the invention of claim 1 or claim 2, the valve portion is connected to the glans storage portion at the fixed end portion and the side edge portion, which prevents the check valve portion from turning inside out toward the glans storage space, thereby reliably preventing urine backflow caused by the check valve portion turning inside out when the internal pressure of the urine storage portion is high.

[0016] According to the urine storage container of the invention of claim 4, in addition to the effects achieved by the invention of claim 1 or claim 2, the thickness dimension of the side edge portion of the valve portion is formed to be larger than the thickness dimension of the central portion, so that the side edge portion of the valve portion exhibits relatively high shape retention compared to the central portion, and therefore it is possible to reliably prevent backflow caused by the check valve portion turning inside out toward the glans storage portion due to the internal pressure of urine stored in the urine storage portion.

[0017] Furthermore, since the thickness dimension of the side edge portions of the valve portion is formed to be larger than the thickness dimension of the central portion, i.e., the thickness of the central portion of the valve portion is formed to be smaller than the thickness of the side edge portions of the valve portion, the central portion of the valve portion has relatively higher flexibility than the side edge portions, so that it opens reliably even when the urine pressure during urination is small, allowing for smooth urination without resistance and the urine to be stored therein.

[0018] According to the urine storage container of the invention of claim 5, in addition to the effects achieved by the invention of claim 1 or claim 2, the thickness dimension of the fixed end portion of the valve portion is formed larger than the thickness dimension of the free end portion, so that the fixed end portion of the valve portion exhibits relatively high shape retention compared to the free end portion, and the tilt of the glans accommodating tube portion that occurs when the urine storage container is attached to the penis and the glans is accommodated in the glans accommodating portion is reliably transmitted to the entire valve portion via the fixed end portion, and the backflow of urine can be more reliably prevented by more reliably closing the opening.

[0019] Furthermore, because the thickness dimension of the fixed end portion of the valve portion is larger than the thickness dimension of the free end portion, i.e., because the thickness dimension of the free end portion of the valve portion is smaller than the thickness dimension of the fixed end portion, the free end portion of the valve portion has relatively greater flexibility than the fixed end portion.Therefore, when the urine storage container is attached to the penis and the glans is stored in the glans storage portion, the valve portions collapse inward and deform while abutting against each other, and the valve openings are automatically and reliably closed, so that reflux of urine can be more reliably prevented even if the amount of urine excreted is small and the internal pressure of the urine storage portion is low.

[0020] In addition, since the free end portion of the valve portion has relatively higher flexibility compared to the fixed end portion, the valve opening opens reliably even when the urinary pressure during urination is small, without interfering with the normal flow of urine, ensuring smooth urination without any resistance.

[0021] According to the urine storage container of the invention of claim 6, in addition to the effects achieved by the invention of claim 1 or claim 2, the valve membrane portion has two abutment surface portions arranged from the side edge portion to the central portion and bent and connected at the central portion to form an abutment angle portion, and the valve opening is formed in a three-pointed star shape, so that the three valve membrane portions abut and tightly contact each other at the abutment surface portions, and the bending line portions of the three valve membrane portions are arranged closely in the central portion of the valve opening to close the valve opening without any gaps, thereby more reliably preventing urine backflow.

DETAILED DESCRIPTION OF THE INVENTION

[0023] First, definitions of terms used to explain the embodiments of the present invention will be given. <Definition of "hardness"> In this specification, "hardness" refers to the hardness value measured in accordance with "JIS K 6253." Because the material used for the urine storage container according to the present invention has an extremely low hardness, it is measured using a Type E durometer (spring-type hardness tester). The higher this measured value, the higher the hardness (i.e., the harder and less likely to deform).

[0024] Therefore, when forming a urine container from a certain material, the lower the hardness of the material, the more easily it can be deformed, that is, the more flexible it will be.

[0025] <Definition of "Extensibility"> In this specification, "extensibility" refers to the ability of a single material or composite material to stretch when the thickness of the material is T (millimeters) and the tensile stress at 70% elongation of the material measured in accordance with "JIS K 6251" is σ (Newtons / square millimeters). 1 / σ×T (millimeters / Newtons) The higher this value, the greater the elongation per unit pressure, i.e., the easier it is to stretch. Also, a "highly stretchable material" refers to a material that has greater elongation when compared at the same thickness.

[0026] <Definition of "stretchability"> In this specification, the term "elongation" refers to the "elongation" measured in accordance with "JIS K 6251," and is a value expressed as a ratio (unit: %) to the test length before the test.

[0027] When the urine container is made of a single material, the material with higher extensibility has a greater elongation per unit pressure, and exhibits physical properties that make it more likely to expand due to the internal pressure of the urine contained therein.

[0028] Furthermore, when the urine container is made of a composite material, the higher the extensibility of the composite material, the greater the elongation per unit pressure, and the more likely it is to expand due to the internal pressure of the urine contained therein.

[0029] As a result, whether it is a single material or a composite material, the higher the extensibility of the material, the greater the elongation per unit pressure, and the more likely it is to expand due to the internal pressure of the urine contained therein.

[0030] Preferred Embodiments The specific form may be any as long as the glans storage section is thinner than the attachment section, the check valve section has three valve membrane sections formed in a tongue shape toward the inside of the urine storage section, and at least the central portions of the three valve membrane sections are separated from each other to form a valve opening, thereby reliably preventing backflow of the stored urine even when the amount of urination is small and the internal pressure of the urine storage section is low.

[0031] <Valve structure> For example, with regard to the thickness dimension of the valve portion, it is preferable that the thickness dimension at the fixed end portion is larger than the thickness dimension at the free end portion, and the thickness dimension can be distributed continuously or discontinuously so that it gradually decreases from the fixed end portion to the free end portion.

[0032] Furthermore, it is preferable that the thickness dimension of the side edge portions is formed to be larger than the thickness dimension of the central portion, and the thickness dimension can be gradually reduced from the side edge portions to the central portion, with a continuous or discontinuous distribution. In particular, the side edge portions alone may be formed in a rib shape that is thicker than the other portions, thereby providing high shape retention.

[0033] Furthermore, when using valve parts having oblique sides, it is preferable to arrange the oblique side of one valve part so that it is adjacent to or abuts the oblique side of another valve part, and the adjacent or abutting oblique side parts may be integrated together to provide a high backflow prevention effect.

[0034] Furthermore, the check valve portion can be configured with three valve membrane portions of the same shape and size, and arranged in three-fold rotational symmetry, but is not limited to this.

[0035] For example, if the glans storage section and / or urine storage section is shaped other than cylindrical, the three valve sections do not have to be the same shape and size, and as long as the three valve sections tilt inward at respective angles from three directions to block the valve opening, and work together to close the valve opening while flexibly deforming in a complementary manner, the configuration and arrangement of the shapes, sizes, etc. can be freely determined.

[0036] In addition, the three tongue-shaped valve portions are connected to the inner wall of the glans accommodating tube portion at the fixed end portion, but depending on the physical properties of the biocompatible resin that constitutes the urine storage container, they can be configured to be connected to the inner wall of the glans accommodating tube portion at the side edge portion in addition to the fixed end portion.

[0037] If the valve portion is connected to the inner wall of the glans accommodating tube portion at the fixed end portion and the side edge portion by forming, for example, a U-shaped connecting portion, when the internal pressure of urine in the urine accommodating portion becomes high, the check valve portion will not turn inside out toward the glans accommodating space, which is preferable as it does not cause backflow of urine due to the check valve portion turning inside out.

[0038] <Biocompatible resin> The biocompatible resin forming the urine storage container according to the present invention can be an elastomer having a low hardness, for example, an elastomer having an ultra-low hardness of 20 degrees or less.

[0039] Furthermore, elastomers with a hardness of 0 to 20 degrees are preferably used because they have a hardness less than that of the skin in many parts of the human body, and therefore can reduce the discomfort felt when worn and carried on the human body.

[0040] Furthermore, elastomers with a hardness of 0 to 10 degrees are less hard than the skin of soft parts of the human body, and can therefore be used preferably because they can further reduce the discomfort felt when worn on the human body and carried around.

[0041] Here, a hardness of 0 degree means that the hardness of the elastomer is a value below the measurement limit of the measuring device used to measure the hardness.

[0042] A measurement method for obtaining hardness using a different definition from those described above is the method using an Asker rubber hardness tester, model F, as a durometer. This measurement method can obtain values ​​of 0 degrees or more for materials with ultra-low hardness, and it is more preferable to use an elastomer with a hardness of 20 degrees or more and 80 degrees or less in this measurement method.

[0043] Next, regarding the extensibility of the elastomer, elastomers with an extensibility of 100 percent or more are suitable for use because the urine storage portion of the urine storage container expands as it stores urine, thereby increasing the storage capacity.

[0044] In particular, elastomers with an elongation of 2000% or more and 3000% or less are even more suitable because they do not substantially restrict the capacity of the urine storage section and have sufficient elongation to allow for long-term use and the storage of large amounts of urine.

[0045] Examples of biocompatible resins that simultaneously satisfy the above-mentioned hardness and elongation requirements include thermoplastic elastomers (TPEs) such as styrene-based, olefin-based, urethane-based, ester-based, PVC-based, and amide-based TPEs. In particular, KURAIN (registered trademark) manufactured by Kuraray Trading Co., Ltd., which is made from a compound containing 5 times or more paraffin oil in a styrene-based thermoplastic elastomer, can be preferably used.

[0046] Furthermore, since human skin exhibits a maximum elongation rate of approximately 70 percent (the rate at which it stretches during normal movement), elastomers with an elongation rate of greater than 70 percent are suitable for use because they do not cause pain or tightness to the user when worn on the human body.

[0047] The biocompatible resin used to form the urine storage container of the present invention may be either transparent or opaque.

[0048] If a transparent resin is used, the state of fitting, the amount of urine held, the color, etc. can be visually confirmed, allowing for quick and accurate fitting and providing convenience for health management, etc. However, if it is desired to avoid the held urine coming into contact with the eyes, an opaque resin can be used to avoid discomfort and protect privacy.

[0049] <Containment Subject> The urine storage container of the present invention is particularly suitable for storing human urine, but can also store other biological fluids that contain water, such as animal blood, lymph, tissue fluid, body cavity fluid, and other bodily fluids, or plant xylem sap or phloem sap, as well as solutions, suspensions, emulsions, and other fluids derived from living organisms that are present within or that flow out, excrete, or are derived from living organisms, and may also store human menstrual blood or feces.

[0050] These biological fluids include those excreted from the excretory organs of animals, including humans; those that flow out from wounds such as cuts, abrasions, contusions, crush wounds, puncture wounds, bites, burns, electric shock wounds, and bedsores in animals or plants; and those that are discharged outside the body via a catheter inserted into the animal or plant body. Therefore, there can be a wide variety of specific configurations for urine storage containers depending on the type, amount, physical properties, and introduction method of the biological fluid.

[0051] For example, when storing urine excreted from the penis, which is a male excretory organ, the attachment part of the urine storage container can be provided with an insertion opening part through which the penis is inserted when attaching it to the penis, and the inside of the cylindrical attachment tube part can be hollow with a circular cross section, but the attachment tube part can also be configured in other shapes depending on the shape of the user's excretory organ, etc. [Example]

[0052] A urine storage container 100 according to a first embodiment of the present invention will be described below with reference to FIGS.

[0053] Here, FIG. 1 is a schematic diagram showing a state in which a user wears a urine storage container according to a first embodiment of the present invention, which is closed by a closure, on the penis; FIG. 2 is a schematic perspective view of a urine storage container according to the first embodiment of the present invention; FIG. 3 is a schematic view of the urine storage container according to the first embodiment of the present invention as seen from the discharge part side; FIG. 4 is a schematic IV-IV cross-sectional view of FIG. 3; FIG. 5 is a schematic VV cross-sectional view of FIG. 3; and FIG. 6 is a schematic VI-VI cross-sectional view of FIG. 4.

[0054] First, the configuration of the urine storage container 100 will be described.

[0055] As shown in FIG. 1, the urine storage container 100 is closed by a closing body WT, and is attached to the penis PN of a human body BD, and is held upright naturally within clothing CL worn by the human body BD.

[0056] <Configuration of urine container> As shown in Figures 2 to 6, the urine storage container 100 is composed of a urine storage section 110, an attachment section 120, an outlet section 130, a glans storage section 140, and a check valve section 150, and each section is integrally formed from a biocompatible resin that has low hardness and high extensibility.

[0057] The biocompatible resin with low hardness and high elongation used in this example is a thermoplastic elastomer, more specifically, KURAIN (registered trademark) manufactured by Kuraray Trading Co., Ltd., which is made from a compound containing 5 times or more paraffin oil in a styrene-based thermoplastic elastomer (TPS: Thermoplastic Styrenic Elastomer), and is an elastomer with a hardness of 10 degrees or less and an elongation of 1500% or more.

[0058] As shown in Figures 2 to 5, the urine storage container 100 has an overall cylindrical appearance, and in this embodiment, when not attached, it has a length dimension of approximately 95 mm and an outer diameter dimension of approximately 20 mm.

[0059] <Configuration of urine storage section> As shown in Figures 2, 4 and 5, the urine storage section 110 has a cylindrical urine storage cylinder part 111, and the inside of the urine storage cylinder part 111 forms a urine storage space AS for storing urine.

[0060] In this embodiment, the thickness of the urine receiving cylinder part 111 when not attached is about 3 mm, and the inner diameter of the urine receiving space AS is about 14 mm.

[0061] In this embodiment, the urine storage section 110 is formed from a thermoplastic elastomer having low hardness and high extensibility, so that when the urine storage container 100 is in use, the biocompatible resin forming the urine storage section 110 stretches significantly, causing the urine storage section 110 to expand significantly outward and store urine.

[0062] <Configuration of the attachment part> As shown in Figures 2, 4, and 5, the mounting part 120 has a mounting tube part 121 formed in a thick cylindrical shape, and the inside of the mounting tube part 121 is a space for accommodating the penis PN.

[0063] The attachment section 120 also has an insertion opening 122 through which the penis PN is inserted when attaching the urine storage container 100 to the penis PN, and is connected to one side of the urine storage section 110 via the glans storage section 140 described below.

[0064] In this embodiment, the thickness dimension TI of the attachment tube portion 121 when not attached is approximately 5 mm, and the inner diameter dimension of the space that accommodates the insertion opening portion 122 and the penis PN when not attached is approximately 10 mm.

[0065] <Configuration of the discharge section> As shown in FIGS. 2, 4, and 5, the discharge part 130 includes a cylindrical tightening tube part 131, and the space inside the tightening tube part 131 serves as a urine discharge path.

[0066] The discharge part 130 also has a discharge port part 132 for discharging urine contained in the urine containing part 110, and is connected to the opposite side of the urine containing part 110 from the attachment part 120.

[0067] In this embodiment, the thickness of the clamping tube portion 131 when not attached is about 6 mm, and the inner diameter of the outlet portion 132 when not attached is about 11 mm.

[0068] When the urine storage container 100 is used, the tightening tube portion 131 is clamped by the closing body WT, and the outlet portion 132 is closed.

[0069] <Configuration of the glans housing part> As shown in Figures 2, 4 and 5, the glans accommodating section 140 has a cylindrical glans accommodating tube portion 141, the inside of which is a glans accommodating space GS that accommodates the glans, and is configured so that when the urine storage container 100 is attached to the penis PN, the user's glans GL is accommodated in the glans accommodating space GS.

[0070] The glans accommodating portion 140 is disposed between the urine accommodating portion 110 and the attachment portion 120 and communicates with them.

[0071] The thickness dimension TG of the glans receiving tube portion 141 when not being worn is smaller than the thickness dimension TI of the wearing tube portion 121 when not being worn.

[0072] In this embodiment, the thickness dimension TG of the glans accommodating cylindrical portion 141 is about 3 mm, and the inner diameter dimension of the glans accommodating space GS is about 16 mm.

[0073] In this embodiment, the entire urine storage container 100 is formed cylindrically from a thermoplastic elastomer having low hardness and high extensibility, and the thickness dimension TG of the glans storage tube portion 141 is formed smaller than the thickness dimension TI of the attachment tube portion 121.

[0074] For this reason, the glans accommodating section 140 is configured to have a higher degree of stretchability than the attachment section 120, and the glans accommodating section 140 is configured to be more likely to expand outward due to pressure from the inside than the attachment section 120.

[0075] Furthermore, since the space for accommodating the penis PN within the attachment part 120 is formed as a space with a smaller diameter than the inner diameter of the glans accommodating space GS, even if the urine storage container 100 is about to fall off from the penis PN when the user's glans GL is placed in the glans accommodating space GS and attached, the glans GL is caught on a step in the space between the glans accommodating part 140 and the attachment part 120, preventing it from falling off.

[0076] <Configuration of check valve section> As shown in FIGS. 2, 4 and 5, the check valve portion 150 is formed to protrude from the inner wall of the glans accommodating portion 140 toward the urine accommodating portion 110 in order to prevent backflow of urine.

[0077] The check valve portion 150 has three valve portions 151 formed in a tongue shape toward the urine storage portion 110, and as shown in Figures 2 and 3, the three valve portions 151 are arranged in a three-fold rotational symmetry with the longitudinal center line CA of the glans storage portion 140 extending in the longitudinal direction of the urine storage container 100 as the rotation axis.

[0078] In other words, the three valve portions 151 are of the same shape and size, and are arranged to face each other at intervals of 120 degrees around the longitudinal center line CA of the cylindrical glans accommodating portion 140.

[0079] As shown in FIG. 2, this longitudinal center line CA coincides with the direction in which urine is discharged from the glans housing portion 140 toward the urine housing portion 110 when a user wearing the urine housing container 100 urinates.

[0080] Therefore, when the urine storage container 100 is not attached to the penis PN, as shown in FIG. 3, at least the central portions 151s of these three valve portions 151 are spaced apart and positioned close to each other, forming a deltoid or tricuspoid valve opening VO.

[0081] That is, the valve opening VO according to this embodiment is formed in a shape of a triangle with each side having an inwardly convex curve.

[0082] The thickness TV of the valve portion 151 varies depending on the location, and as shown in FIGS. 4 and 5, the thickness of the fixed end portion 151b is greater than the thickness of the free end portion 151t.

[0083] In this embodiment, the thickness of the fixed end portion 151b is about 1.1 mm, and the thickness of the free end portion 151t is about 0.9 mm.

[0084] As shown in FIG. 6, the thickness of the side edge portion 151e is greater than the thickness of the central portion 151s.

[0085] In this embodiment, the thickness of the side edge portion 151e is about 1.1 mm, and the thickness of the central portion 151s is about 0.9 mm.

[0086] As described above, the urine storage container 100 comprises a cylindrical urine storage section 110 that forms a urine storage space AS for storing urine, a cylindrical attachment section 120 that is connected to one side of the urine storage section 110 and has an insertion opening 122 for inserting the penis PN, a cylindrical discharge section 130 that is connected to the opposite side of the urine storage section 110 from the attachment section 120 and has an outlet 132 for discharging urine, and a cylindrical discharge section 130 that is arranged between the urine storage section 110 and the attachment section 120. The glans accommodating portion 140 is cylindrical and thinner than the glans accommodating portion 140, and the check valve portion 150 is formed in the glans accommodating portion 140 and prevents the backflow of urine, and is integrally formed from a styrene-based thermoplastic elastomer having low hardness and high extensibility, and the check valve portion 150 has three valve membrane portions 151 formed in a tongue shape toward the inside of the urine accommodating portion 110, and at least central portions 151s of these three valve membrane portions 151 are spaced apart from each other to form a valve opening VO.

[0087] <How to wear> Next, a method of using the urine storage container 100, its state, operation and effects will be described with reference to FIGS.

[0088] Here, FIG. 7 is a schematic cross-sectional view showing the state in which the urine storage container according to the first embodiment of the present invention is attached to the penis, and FIG. 8 is a schematic view of the state in which the urine storage container according to the first embodiment of the present invention is attached to the penis, as seen from the excretion part side.

[0089] When the user attaches the urine storage container 100 to the penis PN, the attachment part 120 of the urine storage container 100 is integrally formed from a thermoplastic elastomer having low hardness and high extensibility, so that the user can easily widen the insertion opening part 122 by applying force to turn the attachment tube part 121 inside out with both hands.

[0090] First, the discharge part 130 is temporarily closed with the closing body WT, and then the insertion opening part 122 is widened and the user's penis PN is inserted into the attachment part 120 from the insertion opening part 122. Then, the user opens the attachment tube part 121 and releases the hand holding it, thereby attaching the urine storage container 100 to the penis PN.

[0091] When inserting the penis PN into the attachment portion 120, if the glans GL is inserted to a position where it fits exactly inside the glans accommodating portion 140, there is no need to adjust the attachment position.

[0092] At this stage, the closure by the closing body WT is loosened, the urine storage section 110 is compressed from the front and rear to remove the air from the urine storage space AS, and then the urine storage space AS is closed again by the closing body WT, so that the urine storage space AS can be used to store urine without waste.

[0093] <Effects when worn> When the urine storage container 100 is attached to the penis PN, the glans GL contained in the glans storage portion 140 exerts a force pushing the glans storage tube portion 141 outward from the inside, as shown by the white arrows in Figures 7 and 8.

[0094] As already explained, the thickness dimension TG of the glans accommodating tube portion 141 is formed to be smaller than the thickness dimension TI of the attachment tube portion 121, and since it is formed from a thermoplastic elastomer having low hardness and high extensibility, the glans accommodating portion 140 has a higher degree of extensibility than the attachment portion 120, and as shown in Figures 7 and 8, the glans accommodating portion 140 expands outward greatly due to pressure from inside, increasing its diameter.

[0095] As a result, as shown in FIG. 7, the glans accommodating cylindrical portion 141 is inclined at an inclination angle θ in a position corresponding to the vicinity of the tip of the glans GL with respect to the state before attachment.

[0096] In conjunction with the tilting of the glans accommodating cylindrical portion 141, the check valve portion 150 formed to protrude from the inner wall of the glans accommodating portion 140 toward the urine accommodating portion 110 tilts and deforms.

[0097] That is, the check valve section 150 has three valve membrane portions 151 formed in a tongue shape facing the urine storage section 110, and when not attached to the penis PN, forms a triangular-shaped valve opening VO as shown in FIG. 3; however, simply by attaching the urine storage container 100 to the penis PN, as shown in FIG. 8, the three valve membrane portions 151, in conjunction with the expansion of the glans storage section 140 and the tilt of the glans storage tube section 141, collapse inward so as to block the valve opening VO from three directions at respective angles, and cooperate while flexibly deforming to automatically close the valve opening VO.

[0098] At this time, since the thickness of each fixed end portion 151b of the three valve membrane portions 151 is formed to be greater than the thickness of the free end portion 151t, the fixed end portion 151b exhibits relatively high shape retention, and the tilt generated in the glans accommodating tube portion 141 is reliably transmitted to the entire valve membrane portion 151 via the fixed end portion 151b.

[0099] Furthermore, since the thickness of each fixed end portion 151b of the valve leaflet portion 151 is formed to be greater than the thickness of the free end portion 151t, i.e., the thickness of the free end portion 151t is formed to be smaller than the thickness of each fixed end portion 151b of the valve leaflet portion 151, the free end portion 151t of the valve leaflet portion 151 has relatively higher flexibility than the fixed end portion 151b, and each valve leaflet portion 151 collapses inward and abuts against each other while flexibly deforming, so that the valve opening VO is automatically and reliably closed.

[0100] In addition, the free end portion 151t of the valve portion 151 has relatively higher flexibility compared to the fixed end portion 151b, so that it opens reliably even when the urinary pressure during urination is small, does not interfere with the normal flow of urine, and more reliably realizes smooth urination without any resistance.

[0101] As shown in Figures 3 and 8, the three valve leaflets 151 are arranged with three-fold rotational symmetry around the longitudinal center line CA of the glans accommodating portion 140 as the axis of rotation. Therefore, even if there is a partial deviation in the inclination angle θ due to the insertion angle of the penis PN around the axis of rotation that is the longitudinal center line CA due to non-uniformity in the shape of the penis PN, the three valve leaflets will flexibly deform in a complementary manner and automatically close the valve opening VO.

[0102] <Prevention of urinary reflux> Subsequently, when urine is stored in the urine storage section 110 due to urination, the internal pressure of the urine pushes the urine storage tube part 111 that forms the urine storage section 110 outward, expanding and deforming, as shown by the black arrow in Figure 7, ensuring sufficient capacity and increasing the internal pressure of the urine storage section 110 in accordance with the amount of urine stored.

[0103] The internal pressure of urine in this urine storage section 110 acts on the three valve membrane parts 151 that make up the check valve section 150, as shown by the black arrows in Figures 7 and 8, pressing the three valve membrane parts 151 against each other and closing the valve opening VO, thereby reliably preventing urine from flowing back.

[0104] Furthermore, when the internal pressure of urine in the urine storage section 110 becomes high, there is a risk of backflow due to the entire check valve section 150 turning inside out; however, since the thickness dimension of the side edge section 151e is formed larger than the thickness dimension of the central section 151s, the shape retention of the central section 151s is higher than that of the side edge section 151e, and therefore it is possible to prevent backflow of urine due to the check valve section 150 turning inside out towards the glans storage space GS.

[0105] When discharging urine stored in the urine storage part 110, the closing body WT is operated while the urine storage container 100 is attached to the penis PN, thereby expanding the tightening tube part 131 of the discharge part 130, releasing the discharge part 130, and discharging the urine from the discharge opening part 132. [Example]

[0106] A urine storage container 200 according to a second embodiment of the present invention will be described below with reference to FIGS.

[0107] Here, Fig. 9 is a schematic perspective view showing a urine storage container according to a second embodiment of the present invention, Fig. 10 is a schematic view of the urine storage container according to the second embodiment of the present invention viewed from the discharge part side, Fig. 11 is a schematic cross-sectional view taken along line XI-XI in Fig. 10, Fig. 12 is a schematic cross-sectional view taken along line XII-XII in Fig. 10, and Fig. 13 is a schematic view of the urine storage container according to the second embodiment of the present invention attached to the penis viewed from the discharge part side.

[0108] The urine storage container 200 is composed of a urine storage section 210, an attachment section 220, an outlet section 230, a glans storage section 240, and a check valve section 250, and each section is integrally formed from an elastomer having low hardness and high extensibility.

[0109] Hereinafter, with regard to the urine storage container 200, the configurations common to the urine storage container 100 of Example 1 will be indicated by changing the numbers in the 100s to numbers in the 200s and the explanation will be omitted, and unless otherwise specifically explained as differences, it will be considered to have the same configuration as the urine storage container 100.

[0110] The following describes the configuration of the urine storage container 200, focusing on the differences from the urine storage container 100.

[0111] <Configuration of check valve section> As shown in Figures 9, 11 and 12, the check valve portion 250 of the urine storage container 200 in this embodiment is formed by protruding toward the urine storage portion 210 and has three valve membrane portions 251 formed in the shape of approximately trapezoidal tongues.

[0112] Each valve portion 251 has two abutment surface portions 251f arranged from the side edge portions 251e to the central portion 251s and bent and connected at the central portion 251s to form an abutment angle portion 251c on the surface forming the valve opening VO.

[0113] Therefore, each valve portion 251 has an abutment angle portion 251c on the surface of the central portion 251s that forms the valve opening VO, and a refraction line portion 251r at a corresponding position on the opposite surface.

[0114] Each valve portion 251 is formed in a generally trapezoidal tongue shape, and has an oblique side portion 251d on the end surface of a side edge portion 251e.

[0115] Here, the hypotenuse portion 251d of one valve portion 251 is arranged adjacent to the hypotenuse portion 251d of another valve portion 251, and the adjacent hypotenuse portions 251d are formed integrally with each other, thereby further improving the shape retention of the side edge portion 251e of the valve portion 251, and more reliably preventing backflow of urine caused by the check valve portion 250 turning inside out toward the glans accommodating space GS when the pressure of the stored urine becomes high.

[0116] The check valve portion 250 has three valve portions 251 of the shape described above, and the three valve portions 151 are arranged in a three-fold rotational symmetry with the longitudinal center line CA of the glans accommodating portion 140 extending in the longitudinal direction of the urine storage container 200 as the rotation axis.

[0117] In other words, the three valve portions 251 are of the same shape and size, and are arranged to face each other at intervals of 120 degrees around the longitudinal center line CA of the cylindrical glans accommodating portion 240.

[0118] Therefore, when the urine storage container 200 is not attached to the penis PN, the check valve portion 250 has at least the central portions 251s of the three valve portions 251 spaced apart and positioned close to each other, forming a three-pointed star-shaped valve opening VO, as shown in FIG. 10.

[0119] That is, the valve opening VO according to this embodiment is formed in a shape in which each side of a triangle is a folded line that protrudes inward.

[0120] <Effects when worn> When the urine storage container 200 is attached to the penis PN, the glans storage portion 240 expands outward due to pressure from the inside, causing the glans storage tube portion 241 to tilt, as shown in FIG.

[0121] In conjunction with the tilt of the glans head accommodating cylindrical portion 241, the check valve portion 250 formed to protrude from the inner wall of the glans head accommodating portion 240 toward the urine accommodating portion 210 tilts and deforms.

[0122] That is, simply by attaching the urine storage container 200 to the penis PN, the three valve membrane portions 251 collapse inward so as to block the valve opening VO from three directions at respective angles in conjunction with the expansion of the glans storage portion 240 and the tilt of the glans storage tube portion 241, and while each deforms flexibly, they cooperate in a complementary manner to automatically close the valve opening VO.

[0123] At this time, the three valve leaflet portions 251 are each arranged from the side edge portion 251e to the central portion 251s and have two abutment surface portions 251f that are bent and connected at the central portion 251s to form an abutment angle portion 251c, forming the valve opening VO in a three-pointed star shape, so that the three valve leaflet portions 251 abut and tightly contact each other at the abutment surface portions 251f, and the refraction line portions 251r of each valve leaflet portion 251 are arranged closely in the center of the valve opening VO, closing the valve opening VO without any gaps.

[0124] <Prevention of urinary reflux> Thereafter, when urine is stored in the urine storage section 210 due to urination, the internal pressure of the urine pushes the urine storage tube portion 211 forming the urine storage section 210 outward, expanding and deforming, as shown by the black arrow in Figure 13, ensuring sufficient capacity, and the internal pressure of the urine storage section 210 increases in accordance with the amount of urine stored.

[0125] As shown by the black arrows in Figure 13, the internal pressure of urine within this urine storage section 210 acts on the three valve membrane portions 251 that make up the check valve section 250, pressing the three valve membrane portions 251 against each other, forcing the abutment surface portions 25f into even stronger contact with each other and positioning the bending line portion 251r even stronger and closer to the center of the valve opening VO, thereby ensuring that the valve opening VO is closed, thereby more reliably preventing the backflow of urine.

[0126] The urine storage container 200 has the structural differences described above compared to the urine storage container 100 of the first embodiment, and therefore, compared to the urine storage container 100 of the first embodiment, the check valve is more reliably closed when attached, and backflow of the stored urine is more reliably prevented even when the amount of urination is small and the internal pressure of the urine storage section is low.

[0127] The urine storage container 200 exerts the same effects as the urine storage container 100 according to the first embodiment, except for the actions and effects related to the above-mentioned differences. [Explanation of symbols]
