Description

[Technical Field]

[0001] The present invention relates to medical components, and more particularly to a rotary valve type spout and medical component that can be used in excrement collection equipment for temporarily collecting excrement, discharged fluids, gas, exudates, secretions, etc. (hereinafter collectively referred to as "excrement"; the same applies hereinafter) excreted from excretory openings created in the human body, as well as excrement collection equipment equipped with the spout. [Background technology]

[0002] In cases where a person is unable to control fecal or urinary excretion at will, or in cases where a person has a disease of the digestive or urinary system, a surgical procedure may be performed to guide the intestines or ureters to the body surface, creating a stoma on the body surface. People with a stoma need to attach a waste collection bag to the stoma to temporarily store waste from the stoma. People with a urinary stoma may also use a leg bag to increase the amount of urine they can collect. People with openings or wounds on the surface of their body due to other diseases also need to attach a waste collection bag around the opening or wound to handle waste discharged by drainage or other means.

[0003] Excrement collection bags, leg bags, and other excrement collection bags are equipped with spouts that are used to discharge excrement accumulated in the excrement collection bag to the outside. The most commonly used spouts are cap valve spouts, which close or open the discharge of excrement by inserting or removing an insert cap into a tubular discharge opening, and rotary valve spouts, which close or open the discharge of excrement with a rotary valve equipped in the discharge opening.

[0004] As an example of a cap valve type fitting, for example, Figures 2 and 3 of Patent Document 1 disclose a fitting in which a closure 140 can be removably coupled to the outlet body 120 by frictional engagement with the outlet body 120 at the outlet opening 122, and the frictional engagement between the stopper 140 and the inner surface 131 is a sealing engagement that substantially prevents or limits unintended leakage of the contents through the outlet opening 122.

[0005] As an example of a rotary valve type fitting, FIG. 1 of Patent Document 2 discloses a fitting that includes a valve body that can be sealed to an associated container, and a stem attached to the valve body that has a portion that is in fluid communication with a fluid storage area, and is configured so that the stem is rotated in a gripping area to move the valve between an open position and a closed position.

[0006] [Patent Document 1] Special Publication No. 2021-522877 [Patent Document 2] Special Publication No. 2013-543788 Summary of the Invention [Problem to be solved by the invention]

[0007] For example, a medical component that is attached to a waste collection bag that collects waste from a stoma and discharges the waste to the outside is a rotary valve-type spout that includes a stem and a stem housing and can adjust the flow of fluid waste. A specific example of a rotary valve mechanism that adjusts the flow of fluid is one in which two openings are provided on the sealing surfaces (two closely-facing peripheral surfaces: the outer peripheral surface of the stem and the inner peripheral surface of the stem housing) provided on the stem and the stem housing, and the stem is rotated left and right to overlap the openings of the stem and the stem housing, thereby discharging the fluid waste downward to the outside.

[0008] In reality, rotary valve devices with such tightly fitting sealing surfaces can allow excrement to leak from the sealing surfaces even when the valve is closed. As a countermeasure to this, double-lock medical components are known, in which a leak-proof cap is attached to the tip of the rotary valve device's outlet. However, if leakage of excrement from the sealing surface of the rotary valve type mouthpiece can be reduced more effectively, users will be able to carry out activities such as daily life and exercise without worrying about excrement leakage or the resulting odor.

[0009] Therefore, a main object of the present invention is to provide a medical component and a waste collection device that can better reduce liquid leakage from rotary valve-type devices. [Means for solving the problem]

[0010] As a result of intensive research into the above-mentioned problems, the inventors discovered a seal structure in which one or more protrusions that can slide against the opposing surface are provided at predetermined positions on the circumferential surface of one of the seal surfaces formed on a rotary valve-type fitting, and completed the present invention.

[0011] The present invention provides a first molded product including a stem housing portion that communicates with a fluid housing portion into which fluid from a waste collection bag that contains fluid from a stoma flows; a second molded product having a substantially cylindrical stem at least a portion of which is accommodated in the stem accommodating portion and which is rotatable within the stem accommodating portion; A rotary valve type mouthpiece is provided, which is at least composed of: the stem housing has an inner circumferential surface with a first opening for regulating the flow of fluid; the stem has an outer peripheral surface that has a second opening that adjusts the flow of the fluid and is arranged to face the inner peripheral surface of the stem accommodating portion, and a hollow flow path that discharges the inflowing fluid to the outside through an outlet when the first opening and the second opening overlap; The inner peripheral surface of the stem accommodating portion or the outer peripheral surface of the stem has at least one circumferential protrusion extending from the first opening and / or the second opening toward the outlet, the circumferential protrusion being in contact with and slidable against an opposing surface. We can provide medical parts. The present invention can also provide a waste collection appliance comprising a waste collection bag for collecting waste from a stoma and a medical component.

[0012] Furthermore, the inner surface of the stem accommodating portion or the outer surface of the stem may have at least one circumferential protrusion portion extending around the entire circumference from the first opening and / or the second opening toward the excrement collection bag, which is in contact with the opposing surface and can slide. The inner surface of the stem accommodating portion or the outer surface of the stem may further have at least one linear protrusion, which is formed on the inner surface on the side of the first opening or on the outer surface on the side of the second opening along the longitudinal direction of the hollow flow path, and may be in contact with and slidable against the opposing surface. The circumferential projection and the linear projection may be formed so as to intersect on the same circumferential surface. The linear protrusions may be arranged singly or in plural on the inner circumferential surface on the side opposite the first opening, or may be arranged singly or in plural on the outer circumferential surface on the side of the second opening. The cross section of the circumferential projection or the linear projection may be substantially semi-elliptical. The second molded product may have a gripping portion for rotating the stem. The rotary valve fitting may be for preventing leakage of fluid and / or for controlling the flow rate of fluid. The medical component may be attached to a waste collection bag that contains fluid waste from the stoma. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a medical component and a waste collection device that can more effectively reduce liquid leakage from a rotary valve type spout. [Brief explanation of the drawings]

[0019] 1. Background and Overview of the Invention

[0020] A stoma is an open opening created by guiding the digestive tract or urinary tract outside the body to provide a route for the discharge of feces and urine after the removal of lesions caused by digestive or urinary diseases. However, a stoma does not have the function of stopping the flow of excrement such as feces and urine, and excrement produced in the body is unconsciously discharged through the stoma. For this reason, a waste collection bag (stoma appliance, leg bag, etc.) is used to collect the excrement discharged from the stoma. Generally, a spout is connected to the outlet of the waste collection bag (stoma appliance, leg bag, etc.) for discharging the excrement, and the spout is equipped with a valve or the like for controlling the flow of the excrement. In addition, people with openings or wounds on the surface of their body due to other diseases may also be provided with a discharge channel or a waste bag for treating the excrement discharged by drainage or the like.

[0021] Generally, rotary valve fittings have a sealing surface formed by combining molded parts that is involved in the valve's opening and closing mechanism. This sealing surface refers to two opposing peripheral surfaces that directly contact each other (e.g., the outer peripheral surface of the stem and the inner peripheral surface of the stem receiving portion), and they are in close contact to seal against liquid leakage and allow for rotation. However, in reality, there are tolerances (allowable errors) when molding molded parts, and perfect contact is not possible due to the rotational movement required to open and close the valve, resulting in small gaps between the opposing surfaces. Furthermore, wear and distortion caused by the rotational movement make gaps more likely to occur between the opposing surfaces. Furthermore, because excrement contains liquid, capillary action occurs between the opposing surfaces, which can lead to liquid leakage.

[0022] To address this issue, conventionally, for example, double-lock medical components have been proposed that include an extremely low rotary valve-type spout with a grip for rotation on the side of the part with the sealing surface involved in the valve opening and closing mechanism, and a short discharge part below the sealing surface, and a large cap that covers the entire exterior of the spout to prevent liquid leakage from the discharge part of the spout. Excrement collection devices that use medical parts of this type are also commercially available.

[0023] The present inventors conducted extensive research into preventing liquid leakage from rotary valve spouts. Using colored water, they investigated a conventional rotary valve spout with a rotatable seal surface where the inner and outer circumferential surfaces are tightly fitted together. They found that the liquid leaks from the gap between the seal surfaces when the seal surfaces (specifically, the inner and outer circumferential surfaces, each of which has an opening) related to the opening / closing mechanism are rotated, resulting in two possible leakage patterns: (1) the leaked liquid migrates from the opening connected to the hollow flow path inside the stem, leaks into the hollow flow path, and then drips out of the outlet; and (2) the leaked liquid migrates to and leaks onto the exterior of the stem, wetting the exterior parts, such as the grip part held with the fingers. While pattern (1) can be prevented by using a cap, pattern (2) cannot be prevented by using a cap because the grip part and the exterior parts of the cap get wet. In the case of pattern (2), one possible solution would be to make the hollow flow path very short and the cap very large, but this would make it difficult for the user to see the spout, and the short length would make it difficult to determine the direction of the discharge destination, making it difficult to handle and less user-friendly.

[0024] Therefore, the inventors' main objective was to provide a medical component and excrement collection device that can better reduce the liquid leakage that can occur in rotary valve-type devices that have a valve opening and closing mechanism and can adjust the flow of excrement fluid.

[0025] As a result of thorough investigation into the above-mentioned problems, the inventors of the present invention have discovered a new sealing structure in which one or more protrusions that can slide in contact with the opposing surface are provided at a predetermined position on one of the opposing surfaces (inner surface or outer surface) where the stem accommodating portion and the stem that constitute a rotary valve having an opening and closing mechanism come into contact, and have come to propose a new technology for reducing or preventing liquid leakage (see, for example, Figures 1, 3 and 11).

[0026] In the present technology, the protrusions that are in contact with and slidable on the opposing surfaces are preferably provided downward and / or upward from the openings that are provided in the stem and stem housing and that regulate the flow of fluid, and more preferably provided at least downward from the openings. Furthermore, in addition to being provided downward from the openings, the protrusions are preferably provided upward from the openings and / or to the sides (specifically, to the left and / or right) from the openings. A circumferential protrusion provided below the openings can more effectively reduce outward leakage. A circumferential protrusion provided above the openings can more effectively reduce outward leakage. A linear protrusion provided laterally from the openings can more effectively reduce inward leakage. As a more preferred embodiment, the positions of the protrusions that can contact and slide on the opposing surfaces are such that protrusions are provided all around the periphery, one above the opening and one below the opening, and that linear protrusions are provided to the left and right of the opening. In this way, by providing the protrusions that can contact and slide on the opposing surfaces so as to surround the opening in all directions (preferably four directions), leakage of fluid inward and leakage of fluid outward can be more effectively reduced. The "upper direction (also referred to as the upper side)" or "upper part" may refer to the direction in which a waste collection bag that contains fluids such as waste from the stoma is located (also referred to as the "waste collection bag direction"), or a part in that direction. The "lower direction (also referred to as the lower side)" or "lower part" of the opening may refer to the direction in which an outlet for discharging waste from the stem to the outside is located (the "outlet direction"), or a part in that direction. The "longitudinal direction" of the hollow flow channel provided inside the stem may be a direction along the central axis of the hollow flow channel, and the "transverse direction" of the hollow flow channel may be a direction perpendicular to the longitudinal direction of the hollow flow channel or a radial direction of the hollow flow channel.

[0027] Furthermore, a preferred embodiment of the present technology is a rotary valve type mouthpiece that is at least composed of a first molded product having a stem accommodating portion, and a second molded product having an approximately cylindrical stem that is at least partially accommodated inside the stem accommodating portion and is rotatable inside the stem accommodating portion.

[0028] <Configuration of rotary valve with opening / closing mechanism> The rotary valve used in the present technology preferably has a rotary opening and closing mechanism that can regulate the flow of excrement fluid from the excrement collection bag into the hollow flow path. Furthermore, the rotary valve is a rotary opening / closing mechanism that uses one or more openings provided on two opposing circumferential surfaces, such as an inner circumferential surface and an outer circumferential surface (hereinafter also referred to as "opposing circumferential surfaces"), and more preferably has a sealing structure in which a protrusion that can contact and slide on the opposing circumferential surface is provided on at least one of the circumferential surfaces. The opposing circumferential surfaces may be two circumferential surfaces that directly contact and face each other, but there may also be a gap (or distance; for example, 1 mm or less) between the two opposing circumferential surfaces, and it is preferable that the gap is at least less than the height of the lower circumferential protrusion. More preferably, the rotary valve has a rotary opening / closing mechanism that provides at least two openings on the side or lateral side of the hollow flow path, and more preferably, the rotary valve has a rotary opening / closing mechanism that utilizes a combination of an opening area on each circumferential surface and another non-opening area.

[0029] A more preferred embodiment of the rotary valve comprises a stem having a hollow flow path therein and a stem housing that can house a portion of the stem, and is configured so that the opening and closing of the valve (adjusting the overlap of the openings) can be adjusted by rotating the stem. The opening and closing mechanism can, for example, rotate one of the shafts to adjust the overlap of the openings on the opposing circumferential surfaces, thereby blocking or allowing the flow of liquid or adjusting the flow of fluid. Preferably, openings are provided on each of the opposing circumferential surfaces so that the lower and upper ends of the openings are aligned when the openings are overlapped by rotating the stem. The lower end of the opening may be the end of the opening facing the outlet, and the upper end of the opening may be the end of the opening facing the waste collection bag.

[0030] In a more specific preferred embodiment, the rotary valve preferably has a mechanism in which a first opening on the inner peripheral surface of the stem housing for regulating the flow of fluid from the waste collection bag and a second opening on the outer peripheral surface of the stem for regulating the flow of fluid into the hollow flow path overlap or do not overlap as the stem rotates, thereby forming an opening that allows fluid from the first opening to pass through the second opening and into the hollow flow path, and a region other than the opening that blocks the flow (also referred to as a "non-opening").Furthermore, it is preferable that the rotation of the stem allows adjustment of the alignment of these openings, and this alignment adjustment allows the first opening and the second opening to overlap to form an opening region that allows the excrement fluid from the waste collection bag to flow into the hollow flow path, while not overlapping to form a non-opening region (region other than the opening region) that blocks the excrement fluid from flowing into the hollow flow path.

[0031] <Stem housing> The stem accommodating portion preferably includes a fluid accommodating portion into which the fluid flows, and more preferably has a structure or shape that communicates with the fluid accommodating object or incorporates the fluid accommodating portion as a recess. The stem accommodating portion preferably has a structure that can accommodate a portion of the stem therein. For example, a space (e.g., a substantially cylindrical shape) that can accommodate the upper portion of the stem may be provided, and a lid for the stem accommodating portion that contacts the lid for the upper portion of the stem may be provided above the space. The stem accommodating portion preferably forms a rotary valve with a sealed structure when combined with a portion of the stem. Furthermore, the stem accommodating portion may function as an attachment portion for attaching to a waste collection bag with a portion of the stem accommodated therein. In a preferred embodiment of the present technology, the stem accommodating portion preferably has a first opening that adjusts the flow of the fluid, and the first opening is preferably provided between the fluid accommodating portion and the stem. Note that the lid on the upper portion of the stem and the lid on the stem accommodating portion may be canopies. Furthermore, it is more preferable that the stem accommodating portion has an inner peripheral surface arranged to face the outer peripheral surface of the stem. Furthermore, it is preferable that the stem accommodating portion has an inner peripheral surface having a first opening, and it is more preferable that the inner peripheral surface is provided between the fluid accommodating portion and the stem. Furthermore, the first opening may be provided by opening a portion of the inner peripheral surface. Furthermore, the inner peripheral surface may have a protrusion that can contact and slide against the outer peripheral surface that is the opposing surface, or may have at least one circumferential protrusion that can contact and slide against the outer peripheral surface that is the opposing surface, and it is preferable that at least one circumferential protrusion be provided below the first opening.

[0032] The space of the stem receiving portion for receiving the stem is preferably approximately cylindrical. The diameter of the approximately cylindrical shape is not particularly limited, but is preferably 3 mm to 20 mm, more preferably 5 mm to 18 mm, and even more preferably 6 mm to 15 mm. The height of the approximately cylindrical shape is not particularly limited, but is preferably 8 mm to 20 mm, more preferably 10 mm to 18 mm, and even more preferably 11 mm to 17 mm.

[0033] <Stem> It is preferable that the stem has a structure that allows the axis to rotate when combined with a part of the stem accommodating portion, and it is preferable that the outer shape of the stem portion accommodated in the stem accommodating portion is a rotatable shape (e.g., an approximately cylindrical shape), and the inner hollow shape is not particularly limited and may be, for example, an approximately cylindrical shape. The stem preferably has an outer peripheral surface facing the inner peripheral surface inside the stem housing, and more preferably has a protrusion on one of the opposing peripheral surfaces as a sealing structure. Preferably, the stem can rotate while the protrusion on one of the peripheral surfaces comes into contact with the opposing peripheral surface as the stem rotates. Preferably, a portion of the stem is combined with the stem housing to form a rotary valve having a sealing structure with a protrusion on the opposing peripheral surface. Furthermore, when the upper part of the stem and the stem housing are combined as a sealing structure part, this combined part may be used as an attachment part.

[0034] In a preferred embodiment of the present technology, the stem preferably has a second opening for adjusting the flow of fluid, and the second opening is preferably provided between the fluid storage portion of the stem storage portion and the hollow flow path of the stem. Furthermore, the stem preferably has an outer peripheral surface having the second opening. The outer peripheral surface may be the outer peripheral surface of the outer diameter of the hollow flow path. Furthermore, the second opening may be provided by opening a portion of the outer peripheral surface. Furthermore, the outer peripheral surface may have a protrusion that can contact and slide against the inner peripheral surface, which is the opposing surface, or may have at least one circumferential protrusion that can contact and slide against the inner peripheral surface, which is the opposing surface, and it is preferable that at least one circumferential protrusion be provided below the second opening.

[0035] Furthermore, it is preferable that the stem has a hollow flow path formed inside or as an inner diameter thereof, through which excrement flowing from the liquid storage portion in the stem storage portion is discharged by overlapping the first opening and the second opening. In a more preferred embodiment, the stem preferably has a second opening that adjusts the flow of fluid, and a hollow flow path through which the first opening and the second opening are overlapped, through which the fluid is discharged to the outside. Furthermore, it is preferable that the stem has an outer peripheral surface that has the second opening and is positioned so as to face the inner peripheral surface of the stem storage portion.

[0036] The stem may also be configured or formed to include an upper portion having a second opening accommodated in the stem accommodating portion as described above, a tubular portion involved in adjusting the length of the hollow flow path, and a discharge portion including a discharge port for discharging waste. The use of the rotary valve of the present technology offers the unprecedented advantage that liquid leakage can be reduced even when the tubular portion is designed to be longer, and that longer portions facilitate the discharge process, such as the direction of discharge. Furthermore, gripping portions can be provided on both the left and right ends of the tubular portion, and the valve can be easily opened and closed by rotating the gripping portions, facilitating the discharge process of waste.

[0037] The stem is preferably approximately cylindrical, and more preferably has a hollow channel space inside and a lid on top. The outer diameter of the stem is not particularly limited, and is preferably 30 mm to 200 mm, more preferably 50 mm to 180 mm, and even more preferably 60 mm to 150 mm. The inner diameter of the stem is not particularly limited, and is preferably 30 mm to 200 mm, more preferably 50 mm to 180 mm, and even more preferably 60 mm to 150 mm. The height (total length) of the approximately cylindrical stem is preferably 8 mm to 20 mm, more preferably 10 mm to 18 mm, and even more preferably 11 mm to 17 mm.

[0038] <Opposite surface> In a preferred embodiment of the present technology, the opposing surfaces refer to an inner peripheral surface facing the outer peripheral surface of the stem inside the stem housing, an outer peripheral surface facing the inner peripheral surface of the stem housing on the outer periphery of the stem, or both of these peripheral surfaces. The opposing surfaces may be in close contact with each other, or there may be a gap between them, but the gap is within a distance that allows a lower circumferential protrusion on one peripheral surface to contact the other peripheral surface and is less than the height of the lower circumferential protrusion. Preferably, the gap is within a distance that allows an upper circumferential protrusion to contact in addition to the lower circumferential protrusion, and / or within a distance that allows a linear protrusion to contact. In this specification, unless otherwise specified, they are also referred to as the inner peripheral surface and the outer peripheral surface, respectively. The opposing surfaces are preferably peripheral surfaces that directly contact and face each other in order to further reduce liquid leakage, and it is more preferable that the surfaces other than the above-mentioned protrusions are smooth surfaces.

[0039] <Opening> The opening is preferably a first opening provided in the stem housing and / or a second opening provided in the stem. By adjusting the degree of overlap between the first opening and the second opening, the flow of fluid can be blocked when they do not overlap and allowed when they overlap, and the flow rate of the fluid can also be adjusted. The first opening and the second opening are preferably arranged on the inner circumferential surface of the stem housing and the outer circumferential surface of the stem, respectively, so that the upper and lower ends of the first opening and the second opening are in the same position when the stem is rotated. Note that the upper end may be the end toward the excrement collection bag, and the lower end may be the end toward the discharge outlet. The shape of the opening is not particularly limited, but examples include polygonal shapes (e.g., approximately triangular, approximately square, approximately hexagonal, etc.) and approximately elliptical shapes (including approximately circular shapes), with approximately rectangular, approximately square, etc. being preferred. The first opening and the second opening are preferably the same shape. The opening angle of the opening is the angle (θ) formed by the left and right ends of the opening (left and right ends) and the center (central axis) of the rotation axis of the stem. In the case of the opening angle (θ) of the first opening, the center (central axis) constituting the opening angle may be the center (central axis) of the lid hole (or inner peripheral surface) of the stem accommodating section.

[0040] It is preferable that the length of the arc of the circumferential surface of the opening region of one opening be shorter than the length of the arc of the circumferential surface of the non-opening region of the other opening, and it is more preferable that the opening angle of the first opening be less than 180°, taking into consideration the width of the inlet of the fluid storage portion in the stem storage portion. Furthermore, it is preferable that the height of both openings be less than the height of the circumferential seal surface, more preferably within the range from the lower circumferential protrusion to the upper end of the circumferential seal surface, and even more preferably within the range of the lower and upper circumferential protrusions.

[0041] The opening angle of the opening is not particularly limited for either the first or second opening, but a suitable lower limit is preferably more than 0°, more preferably 5° or more, even more preferably 10° or more, more preferably 15° or more, more preferably 30° or more, and more preferably 40° or more, and a suitable upper limit is preferably less than 360°, preferably 180° or less, more preferably 120° or less, preferably 100° or less, and more preferably 90° or less. In a more preferred embodiment, the opening angle of the first opening is preferably 25° to 120°, more preferably 30° to 110°, and even more preferably 40° to 100°.

[0042] The opening angle of the opening may be the same as the opening angle (θ1, θ2) of the first opening and the second opening, and may be the same or different, but it is preferable that the angles of the openings are approximately the same. Referring to FIG. 7, the opening angle is preferably determined by using the center of the upper convex portion of the stem as the center when calculating the angle, and the angle formed by the center and both left and right ends (arcs) of the opening. Since the upper convex portion of the stem and the hole in the stem housing lid are rotatably fitted together, making the center of the upper convex portion and the center of the hole approximately the same, in the case of the first opening, the center when calculating the angle may be the center of the hole in the stem housing lid. In addition, the arc length of the opening of the opening in a preferred embodiment may be calculated from the angle and radius of the above-mentioned preferred upper and lower limit values, which may be used as the preferred upper and lower limit values.

[0043] The height of the opening is not particularly limited for either the first or second opening, but a suitable lower limit is preferably 2 mm or more, more preferably 3 mm or more, and even more preferably 4 mm or more, and a suitable upper limit is preferably 10 mm or less, more preferably 8 mm or less, and even more preferably 7 mm or less.

[0044] From the viewpoint of reducing liquid leakage, it is preferable that the first opening and the second opening have approximately the same shape and approximately the same size (length, width, maximum diameter, minimum diameter, major diameter, minor diameter, diameter, etc.), and in terms of the same size, the area ratio of [second opening / first opening] is preferably 95% or more, more preferably 98% or more, even more preferably 99% or more, and even more preferably approximately the same (99.9 to 100%).

In the present technology, it is preferable that at least one protrusion is provided below the opening as a circumferential protrusion around the entire periphery.

[0046] The circumferential projection is preferably formed so as not to pass through the opening when the stem is rotated, and may be formed on the circumferential surface in one or a combination of straight lines, wavy lines, oblique lines, etc., but from the viewpoint of reducing liquid leakage, it is more preferable that it is formed around the entire circumference. The entire circumference may be formed in a line, or may be formed around the circumferential surface with multiple oblique lines intersecting each other, but from the viewpoint of ease of molding, a straight line is more preferable, and a circumference that is approximately perpendicular to the central axis of the stem rotation shaft is even more preferable.

[0047] When the circumferential protrusion is provided below the opening, it is more preferable that the downward circumferential protrusion be further disposed between the lower end of the surface (sealed circumferential surface) where the inner circumferential surface of the stem accommodating portion and the outer circumferential surface of the stem are in contact. A specific example of a suitable arrangement of the circumferential protrusion is, in the longitudinal direction of the stem, the distance from the lower end of the first opening and / or the second opening to the lower end of the sealed circumferential surface is defined as 100%, and the lower end of the first opening and / or the second opening is defined as the starting point (0%).

[0050] Furthermore, when the circumferential protrusion is provided above the opening (L2), the circumferential protrusion located above is preferably within a range of up to 5 mm above the top end of the opening, more preferably up to 4 mm above, and even more preferably up to 3.5 mm above, and the preferred range is more preferably within a range of 0.5 to 3.5 mm above the top end of the opening, and even more preferably within a range of 0.5 to 3 mm.

[0051] The linear protrusions are preferably provided linearly in the longitudinal direction of the stem, and may be formed on the peripheral surface in one or a combination of straight lines, wavy lines, oblique lines, etc., and may be formed so as to pass through an opening in the opposing surface when the stem is rotated. Furthermore, it is more preferable that the linear shape is a line that is approximately parallel to the central axis of the stem rotation shaft. From the viewpoint of reducing liquid leakage, it is more preferable that the linear protrusion portion be formed in the lateral direction of the first opening and / or the lateral direction of the second opening so that when the first opening and the second opening are overlapped to form an opening, the linear protrusion portion is positioned in the lateral direction (left side and / or right side) of the overlapping opening. The linear protrusions are preferably provided in the vertical direction at least as far as the downward and / or upward circumferential protrusions, and more preferably at least as far as the downward circumferential protrusions. The upper and / or lower limits of the linear protrusions in the vertical direction may be the upper and / or lower limits of the seal peripheral surface in the vertical direction.

[0052] It is preferable that one or more linear protrusions are arranged on the inner peripheral surface on the opposite side of the first opening (180° or more and 270° or less from the starting point of the first opening), or that one or more linear protrusions are arranged on the outer peripheral surface on the side of the second opening (within 90° left or right from the starting point of the second opening).

[0053] In a preferred embodiment, in the case of a single or multiple linear protrusions arranged on the inner surface of the stem accommodating portion, the linear protrusions are preferably formed on the inner surface along the height direction in the lateral direction of the first opening (preferably either the left or right side or both), and are capable of sliding in contact with the outer surface. In a preferred embodiment, when one or more linear protrusions are provided on the outer peripheral surface of the stem, the linear protrusions are preferably formed on the outer peripheral surface along the longitudinal direction of the stem in the lateral direction of the second opening (preferably either the left or right side or both), and are linear protrusions that are in contact with and can slide on the inner peripheral surface. It is more preferable to provide at least two linear protrusions on both the left and right sides of the second opening, and when there are multiple linear protrusions, it is more preferable that they are arranged symmetrically when viewed from above.

[0054] Furthermore, it is preferable that the circumferential protrusions and linear protrusions are formed so as to intersect on the same circumferential surface, for example, a cross intersection of circumferential and linear protrusions (preferably approximately perpendicular), or an intersection of two parallel circumferential protrusions with two balanced linear protrusions (preferably approximately perpendicular). In a preferred embodiment, the circumferential projections and linear projections arranged on the inner peripheral surface of the stem accommodating portion are preferably formed so as to intersect with each other. In a preferred embodiment, the circumferential projections and linear projections arranged on the outer peripheral surface of the stem are preferably formed so as to intersect with each other.

[0058] Furthermore, the cross section of a suitable protrusion is not particularly limited for either or both of the circumferential and linear protrusions, and is preferably polygonal (triangular, rectangular, hexagonal, etc.) or approximately semi-elliptical (including approximately semi-circular), and is preferably formed so that the portion in contact with the opposing surface is rounded; for example, it may be triangular with a rounded tip, and of these, an approximately semi-elliptical shape is preferred.

[0059] The length of the base of the cross section of the protrusion (the length of the arc in contact with the peripheral surface) is not particularly limited, whether it is circumferential or linear, but a suitable lower limit is preferably 0.05 mm or more, more preferably 0.2 mm or more, and even more preferably 0.3 mm or more, and a suitable upper limit is preferably 1 mm or less, more preferably 0.8 mm or less. The cross-sectional height of the protrusion (height from the peripheral surface) is not particularly limited, whether it is circumferential or linear, but a suitable lower limit is preferably 0.05 mm or more, more preferably 0.1 mm or more, and even more preferably 0.5 mm or more, and a suitable upper limit is preferably 1 mm or less, more preferably 0.8 mm or less, and even more preferably 0.5 mm or less.

[0060] <Hollow channel> In a preferred aspect of the present technology, the hollow flow channel is preferably formed inside the stem and has a structure connectable to the fluid storage section of the stem housing, and is preferably connected to the fluid storage section via the first opening and the second opening at a lateral portion of the upper part of the hollow flow channel. The hollow flow channel is preferably configured so that excrement liquid from the excrement storage bag flows into the hollow flow channel through an opening formed by the overlap of the first opening and the second opening, and the flowed-in liquid is discharged from an outlet disposed downward. The shape of the hollow flow channel is not particularly limited, and is preferably a cylindrical shape that allows liquid to flow in from the side above and be discharged from the bottom, and a hollow cylindrical shape is more preferable. A top convex portion is preferably provided at the top of the hollow flow channel as a lid. The top convex portion is preferably fitted into a hole in the center of the lid of the stem housing, and preferably can also serve as part of the rotary shaft of the rotary valve by fitting. The protrusion at the upper end preferably has a structure that becomes a hook after being fitted into the hole in the center of the lid of the stem accommodating portion, and is preferably made of, for example, a flexible resin, with a shape and structure that allows for a snap foot.

[0061] The diameter of the hollow flow path (stem inner diameter) is not particularly limited, but a suitable lower limit is preferably 3 mm or more, more preferably 4 mm or more, and even more preferably 5 mm or more, and a suitable upper limit is preferably 15 mm or less, more preferably 14 mm or less, and even more preferably 13 mm or less.

[0062] <Mounting part and grip part> In a preferred embodiment of the present technology, the stem accommodating portion preferably functions as an attachment portion when attached to the excrement collection bag, is preferably long in the horizontal direction (or radial direction), and is preferably approximately rectangular or rectangular with rounded corners when viewed from the front or from above. The stem accommodating portion is preferably a support portion that can accommodate a portion of the stem, and is preferably asymmetrical across the stem by having a liquid storage portion, although a symmetrical shape is also acceptable. A tubular section having the hollow flow path as its inner diameter is preferably disposed below the stem housing section, and more preferably the tubular section is disposed below the rotatable seal peripheral surface. Furthermore, it is preferable to provide a gripping section at one or both ends of the tubular section from the viewpoint of rotational operation. Furthermore, the longer the tubular section, the easier it is to check the direction of discharge and the position of the gripping section, which is preferable. The height of the tubular portion is not particularly limited, but a suitable lower limit is preferably 10 mm or more, more preferably 20 mm or more, and even more preferably 25 mm or more, and a suitable upper limit is preferably 60 mm or less, more preferably 50 mm or less, and even more preferably 45 mm or less. Note that the height of the tubular portion is preferably the distance from the lower end of the upper part of the stem, which has the sealing circumferential surface portion, to the upper end of the discharge part, which has the discharge port.

[0063] A stem rotation stopper may be provided on the support part on the liquid storage part side and / or the support part on the opposite side below the stem storage part to come into contact with the rotating gripping part and limit the stem rotation to a predetermined angle (e.g., 160° to 200°, 180°), and a rotation stopper may also be provided on the gripping part to cooperate with the stem rotation stopper to limit rotation. The left and right width of the gripping portion is not particularly limited, but may be approximately the same as the left and right width of the stem accommodating portion, for example, about 2 cm to 5 cm.

[0064] It is preferable that the positions of both ends of the stem accommodating portion (mounting portion) are different from the positions of both ends of the gripping portion. This difference allows the user to understand the positions of the mounting portion and the gripping portion without having to look toward the discharge outlet to check their positions, and the user can hold the mounting portion and rotate the device by holding the gripping portion.

[0065] <Rotary valve type mouthpiece>

[0066] The rotary valve type device of the present technology may be a rotary valve type device used to prevent leakage of liquid and / or a rotary valve type device used to control the flow rate of fluid. Furthermore, the present technology can provide a medical component including the above-described rotary valve as a fitting. The above-described rotary valve may be used as a rotary valve type fitting. The present technology may further include a cap that fits onto the tip of the outlet to prevent leakage, and can provide, for example, a medical component that includes the rotary valve type spout and cap described above. For example, from the perspective of further preventing leakage of excrement, the medical component preferably includes a rotary valve type spout and a cap that fits over the outlet of the rotary valve type spout. The rotary valve type spout may also be connected to the cap via a connecting portion (e.g., flexible resin). The rotary valve type spout preferably has a protrusion on the outer periphery of the outlet that allows the cap to be inserted and covered to a predetermined position. More specifically, the protrusion may be tapered downward to facilitate cap fastening and cap removal. A connector tube can also be connected to the outlet of the rotary valve.

[0067] The rotary valve type fitting of the present technology may be used as a medical component. Examples of the medical component include a medical component used for one or more of an ostomy appliance waste collection bag, a drainage waste collection bag, a feces bag, a urine collection bag, a urine collection bag, a leg bag, etc. In the case of a rotary valve type fitting used as a medical component, it may be a rotary valve type fitting for a waste collection appliance. A bag used to accumulate a larger amount of waste preferably includes a connection part that connects the outlet or stoma hole of the ostomy appliance with a tube or the like, a bag for accumulating waste, and the fitting according to the present embodiment for discharging the accumulated waste to the outside.

[0068] The rotary valve type fitting described above is preferably attached to a waste collection bag, and examples of such waste collection bags include, but are not limited to, waste collection bags, bags, etc. Of these, the rotary valve type fitting is preferably attached to a waste collection bag or bag that contains waste, but the use of the waste collection bag is not particularly limited, and examples include stomas (e.g., colostomy, ileostomy, urostomy, etc.), drains, etc., from which one or more types can be selected.

[0069] Furthermore, the rotary valve type device is more preferably a rotary valve type device for excrement collection equipment used for low-viscosity excrement, and the low-viscosity excrement collection equipment is preferably one or more types selected from, for example, devices for ileostomy and urostomy.

[0070] The rotary valve type mouthpiece of the present technology preferably comprises a stem accommodating portion and a sealing peripheral portion configured to be rotatable from the top of the stem, a tubular portion arranged below this and configured with a gripping portion and a hollow flow path, and a discharge portion arranged below this and capable of attaching and detaching a cap. The size of the rotary valve spout of the present technology can be changed appropriately depending on the excrement collection bag to be used, with the vertical height being, for example, 20 to 70 mm, preferably 30 to 60 mm, the horizontal width being, for example, 20 to 70 mm, preferably 30 to 60 mm, and the depth being, for example, 5 to 30 mm, preferably 5 to 20 mm. By adopting the present technology, the vertical height of the spout and the height of the hollow flow path (e.g., tubular portion) can be increased, and the area that can be recognized with a finger or the like is increased, making the user's work easier, including the direction of discharge. This technology can be used for small, vertically long rotary valves, for example, between 3 mm and 8 mm, and the advantage of this technology is that it can reduce liquid leakage even when made compact.

[0071] The rotary valve spout can be molded using a resin material by known molding methods such as injection molding or mold molding. For example, the rotary valve spout can be obtained by molding the first and second molded products described above, and then assembling them by pushing the second molded product into the hole in the lid of the first molded product so that the upper end protrusion of the second molded product fits into the hole. Another advantage of the rotary spout of this embodiment is that it can be manufactured using such a simple molding method. Examples of resin materials that can be used include ultraviolet-curing resin and thermoplastic resin. The first and second molded products are made of flexible resin, which provides a smooth and flexible circumferential surface of the rotating part, thereby providing a sealing effect to prevent liquid leakage. Even if the protrusions used in this technology are provided on the circumferential surface of the rotating part, the protrusions can slide in contact with the opposing surface, maintaining the sealing effect between the circumferential surfaces and providing the protrusions to prevent liquid leakage. Examples of resin materials for the rotary valve type spout include polyethylene, polypropylene, vinyl acetate, etc., and it is preferable to use one or more of these.

[0072] In the past, when the viscosity of excrement from a small intestinal stoma (ileostomy) or a urinary stoma (urostomy) was low, excrement could leak from the fitting attached to the excrement collection bag (stoma appliance, leg bag, etc.). However, with this technology, even when the viscosity of excrement is low, it is possible to effectively reduce excrement leakage, and the use of a rotary valve also has the advantage of making the excrement discharge process easier. It is also preferable to apply a lubricant such as silicone oil to the sealing surface of the rotary valve fitting from the viewpoint of sealing.

[0073] Therefore, this technology provides a medical component and a waste collection device that can effectively reduce fluid leakage from a rotary valve. Specifically, fluid leakage from the rotatable seal circumferential surface (the two opposing circumferential surfaces, the outer and inner circumferential surfaces) of a rotary valve-type spout can be prevented. This prevents fluid leakage onto the external surface of the spout and prevents fluid leakage from the spout's outlet. Preventing fluid contamination of the external surface with excrement is also desirable from a hygienic perspective. This prevents fluid leakage from becoming soiled by excrement while the user is engaged in daily activities or during excrement disposal. Furthermore, the spout can be easily rotated during excrement disposal, making the excrement disposal process easier for the user. Furthermore, the spout can be made taller, allowing the user to easily view the entire spout or the grip portion below, making it easier to determine the direction of the spout's outlet and thus simplifying the excrement disposal process.

[0074] <Preferred embodiment of the present technology> In a preferred embodiment, the present technology provides a rotary valve including at least a first molded product having a stem accommodating portion, and a second molded product having a substantially cylindrical stem at least a portion of which is accommodated in the stem accommodating portion and is rotatable within the stem accommodating portion; the stem housing has an inner circumferential surface with a first opening for regulating the flow of fluid; the stem has an outer peripheral surface that has a second opening that adjusts the flow of the fluid and is arranged to face the inner peripheral surface of the stem accommodating portion, and a hollow flow path that discharges the fluid to the outside when the first opening and the second opening overlap; A medical component can be provided in which the inner surface of the stem accommodating portion or the outer surface of the stem has at least one circumferential protrusion portion along the entire circumference, below the first opening or the second opening, that is in contact with and can slide against an opposing surface. In a more preferred embodiment, the rotary valve is configured to permit and prevent fluid from the first opening from passing through the second opening into the hollow flow path by rotationally aligning the first opening with the second opening. In a more preferred embodiment, the inner surface of the stem accommodating portion preferably has at least one circumferential protrusion portion around the entire circumference that can contact and slide against the outer surface below the first opening or the second opening, or the outer surface of the stem preferably has at least one circumferential protrusion portion around the entire circumference that can contact and slide against the inner surface below the first opening or the second opening.

[0075] Furthermore, the present technology can also provide a waste containment appliance (for example, a stoma appliance) that includes the above-mentioned rotary valve as a fitting. In addition, in the present technology, it is preferable to provide a tubular portion including a discharge flow path for excrement below the stem housing portion, and more preferably, the tubular portion has a grip portion.

The gripping portion 26 is preferably arranged in a rotatable state in contact with the lower side of the stem accommodating portion 10a, and more preferably arranged on one or both sides of the tubular portion of the stem.

[0090] FIG. 3 is a cross-sectional view (sectional line AA' in FIG. 2) passing through the center of the rotary axis in the Z-axis direction (plane of the Z-axis and Y-axis) of the rotary valve type spout 1a of the first embodiment. The stem housing 10a has a first opening 11 for adjusting the flow rate of the fluid and an inner circumferential surface 12 having the first opening 11. The stem 20a has a second opening 21 for adjusting the flow rate of the fluid and an outer circumferential surface 22 having the second opening 21. The inner circumferential surface 12 and the outer circumferential surface 22 are opposed to each other, and it is preferable that openings and protrusions are provided within this opposing range (within the opposing area). The circumferential protrusions 31, 31 and vertical protrusions 32, 32 provided on the inner circumferential surface 12 are in contact with the outer circumferential surface 22, thereby reducing liquid leakage from the rotary valve. When at least the entire lower circumferential protrusion 31 is in contact with and slidable on the outer circumferential surface 22, a gap may be provided between the inner circumferential surface 12 and the outer circumferential surface 22, or they may be in close contact. Furthermore, the lower and upper circumferential protrusions 31, 31 are located within the height range of the above-mentioned seal structure portion.

[0091] FIG. 4 is a cross-sectional view of the stem accommodating portion 10a of the first molded product 100a used in the first embodiment in the Z-axis direction (Z-axis / X-axis plane). The stem accommodating portion 10a has an inner peripheral surface 12 therein, in which a portion (outer peripheral surface) of the stem 20a is accommodated. A (substantially cylindrical) lid 14 protrudes from the stem accommodating portion 10a so that the upper portion of the stem 20a does not penetrate through the stem accommodating portion 10a, and the lid 14 has a hole 15. The second molded part 200a is formed by moving an upper end protrusion 25 provided on the lid of the stem 20a along the inner peripheral surface 2, fitting the upper end protrusion 25 into the hole 15 and stopping at the lid 14, whereby the first molded part 100a and the second molded part 200a are fixed so that the stem can rotate, and the medical part 300a is formed.

[0092] The inner surface 12 of the stem accommodating section 10 is provided with circumferential protrusions 31, 31 on the entire circumference above and below the first opening 11, and it is preferable that the entire circumference of the circumferential protrusion 31 on the upper side and the entire circumference of the circumferential protrusion 31 on the lower side are approximately parallel (approximately perpendicular). 4, one linear protrusion 32 is provided in the longitudinal direction of the hollow flow path, and preferably one linear protrusion 32 is also provided in the longitudinal direction of the hollow flow path in the cross-sectional view from the back, and these protrusions 32, 32 are more preferably parallel to the central axis of the stem. These protrusions 32, 32 are preferably symmetrical when viewed from above.

[0093] In FIG. 5, circumferential protrusions 31, 31 are provided around the entire circumference, and linear protrusions 32, 32 are provided in the height direction. The height of the circumferential protrusions 31 around the entire circumference in the downward direction is preferably less than the distance of the gap between the inner circumferential surface 12 and the outer circumferential surface 22, and the height of the protrusions other than the circumferential protrusions around the entire circumference in the downward direction is preferably less than the gap. Note that grooves may be formed on the opposing circumferential surfaces when the protrusions are in close contact with the opposing circumferential surfaces. FIG. 5A is a cross-sectional view of the first molded product 100a viewed from the right side, taken along the Z-axis direction (plane of the Z-axis and X-axis) and passing through the center of the hole 15 in the lid 14. FIG. 5B is a cross-sectional view of the first molded product 100a viewed from the left side, taken along the Z-axis direction (plane of the Z-axis and X-axis) and passing through the center of the hole 15 in the lid 14.

[0094] The provision of the circumferential projection 31 in a straight line below the first opening 11 prevents liquid leakage caused by the opposing rotating surfaces (the inner peripheral surface 12 of the stem accommodating portion 10 and the outer peripheral surface 22 of the stem 20a). The downwardly disposed circumferential projection 31 is preferably located 0 cm below the lowest end of the first opening 11. It is more preferable that the circumferential projection 31 be located above the lowest end of the inner peripheral surface 12, and even more preferably above the lowest end of the two peripheral surfaces (e.g., the above-mentioned seal structure portion) formed by the inner peripheral surface 12 and the outer peripheral surface 22. This makes it possible to prevent liquid from leaking onto the exterior of the stem and into the hollow flow path.

[0095] Furthermore, providing the circumferential protrusion 31 all around above the first opening 11 can more effectively prevent liquid leakage from the rotating seal surface. For example, providing the circumferential protrusion 31 all around above the first opening 11 can prevent liquid from flowing into the opposing surface and rising above the opening, which can result in leakage, due to an increase in the flow rate from the excrement collection bag.

[0096] Furthermore, it is preferable that linear protrusions 32, 32 are provided in the longitudinal direction of the hollow flow path on the inner peripheral surface 12 opposite the first opening 11. By combining these circumferential protrusions and linear circumferential protrusions, a predetermined frame (space) can be provided by at least four protrusions, and the fluid can be retained within this frame (space), thereby more effectively preventing liquid leakage that is prevented by the circumferential protrusions.

[0097] FIG. 6 is a cross-sectional view of the stem 20a of the second molded product 200a used in this first embodiment in the Z-axis direction (Z-axis / X-axis plane). The second molded product is provided with a second opening 21 that adjusts the flow rate in cooperation with the first opening 11. From the viewpoint of preventing liquid leakage, it is preferable that the first opening 11 and the second opening 21 have substantially the same size and shape. The second opening 21 is provided on the outer peripheral surface 22 that faces the inner peripheral surface 12 of the stem accommodating portion 11. The inner peripheral surface 12 may be either rough or smooth except for the protrusions, but a smooth surface is preferred. The outer peripheral surface 22 is preferably smooth to allow the protrusions to slide easily, and it is preferable that no protrusions are provided on the outer peripheral surface 22. Note that alignment may be performed by fitting the protrusions on the inner peripheral surface with grooves on the outer peripheral surface. When the first molded product 100a and the second molded product 200a are combined to form the medical component 300a, the circumferential protrusions 31, 31 and the linear protrusions 32, 32 come into close contact with the outer circumferential surface 22 as shown in Figure 3, thereby enhancing the liquid leakage prevention effect. Furthermore, it is preferable that these protrusions are provided in a state where they can slide even when the stem is rotated. The opening angle of each of the first opening and the second opening is preferably 20 to 60°, the height of each opening is preferably 5 to 20 mm, and the height of the protrusion is preferably 0.5 to 1 mm.

[0098] A gripping portion 26 for adjusting the opening and closing of the first opening 11 and the second opening 21 by rotation is preferably provided on the exterior of the stem 20a below the seal circumferential surface. By rotating the gripping portion 26, the opening and closing of the openings can be adjusted, allowing, blocking, and adjusting the flow rate. Furthermore, a rotation stopper 27 is preferably provided on the gripping portion 26, and the rotation stopper 27 of the gripping portion 26 and the rotation stopper 14 provided at the bottom of the stem accommodating portion 10 may cooperate to allow the gripping portion to rotate from approximately 0° to 180°, stopping at 180°.

[0099] Furthermore, a hollow flow path 23 is provided inside the stem 20a as an inner diameter for discharging excrement to the outside. The second opening 21 overlaps with the first opening 11, forming openings on the side and lateral sides of the hollow flow path. Excrement from the fluid storage section 13 flows into the hollow flow path 23 through the lateral and lateral openings, flows downward within the hollow flow path 23, and is discharged from an outlet 24 at the bottom of the hollow flow path 23. In the case of the rotary valve-type spout 1a, the hollow flow path can be made longer to facilitate the discharge of excrement. The rotary valve-type spout 1a may further include a cap that can be fitted onto the outer periphery of the outlet 24 to prevent leakage. In this case, the cap may be connected to the stem 20a via a connecting band and provided on the second molded product. When the cap is attached to the outlet 24, the tip of the cap can be secured with a connecting stopper 28. The connecting stopper can be used as appropriate for something other than a cap, and may be used, for example, as a stopper for a connecting tube when connecting a connecting tube such as a drain to the outlet 24.

[0100] The upper part of the stem 21 is provided with an upper-end protrusion 25, which comprises an upper member having a generally cylindrical shape that fits into the hole in the lid 14 and acts as a hook to prevent disengagement; a middle member having a generally cylindrical shape with a smaller diameter than the upper part and that can rotate against the circumferential surface of the hole 15 after fitting; and a lower member having a generally cylindrical shape that serves as a lid for the hollow flow channel 23 and that tightly contacts the lid on the inner circumferential surface of the stem accommodating portion 10a. The tip of the upper-end protrusion 25 is preferably tapered, widening downward, to facilitate passing through the hole 15 and subsequent fitting. The upper member of the upper-end protrusion 25 is inserted into the hole 15 in the lid 14 of the stem accommodating portion 10 and then fitted to form a rotary valve-type mouthpiece 1a including the stem 20a and the stem accommodating portion 10a. After formation, the upper end protrusion 25 becomes the axis of rotation when the stem rotates, and the protrusions 31, 31, 32, 32 on the inner peripheral surface 12 and the outer peripheral surface 22 come into close contact with each other and slide against each other, allowing the stem to rotate left and right.

[0101] 7 is a cross-sectional view of the medical component 100a according to the first embodiment, taken along the Y-axis and Z-axis, with the first opening 11 and the second opening 21 closed. In FIG. 7, the second opening 21 does not overlap the first opening 11 and is located on the opposite side of the first opening. When the first opening 11 and the second opening 21 do not overlap, the non-second opening region (the region other than the openings on the outer peripheral surface) prevents excrement from the fluid storage portion 13 from flowing into the hollow flow path 23. The inner peripheral surface 12 and the outer peripheral surface 22 are opposed surfaces, and the protrusions 36, 36, 37, 37 of the outer peripheral surface 22 contact and slide against the inner peripheral surface 12, allowing rotation left and right. In this case, at least one circumferential protrusion 31 is provided on the inner circumferential surface 12, extending along the entire circumference, downward from the first opening 11 and the second opening 21. This downward circumferential protrusion 31 prevents liquid from leaking downward from the seal circumferential surface. Furthermore, one circumferential protrusion 31 is provided on the inner circumferential surface 22, extending along the entire circumference, upward from the first opening 11 and the second opening 21. This prevents liquid from leaking upward from the seal circumferential surface.

[0102] 8 is a cross-sectional view of the stem accommodating portion 10a used in the first embodiment taken along the Z-axis. Linear protrusions 32, 32 are provided at symmetrical positions on the opposite side (approximately in the range of 120° to 150°) of the first opening 11. The inner peripheral surface 12 is smooth except for the protrusions, allowing the stem 20a, which has the outer peripheral surface 22 as the opposing surface, to rotate smoothly.

[0109] The cross section of the circumferential projection 36 and / or the linear projection 37 is preferably substantially semi-elliptical.

[0110] The second molded product 200b preferably has a gripping portion 26 for rotating the stem 20b, and is preferably arranged in a rotatable state in contact with the lower side of the stem accommodating portion 10b.

[0111] FIG. 11 is a cross-sectional view (cross-sectional line AA' in FIG. 2) passing through the center of the rotary axis in the Z-axis direction (plane of the Z-axis and Y-axis) of the rotary valve type spout 1b of the second embodiment. The stem housing 10b has a first opening 11 for adjusting the flow rate of the fluid and an inner circumferential surface 12 having the first opening 11. A fluid housing 13 is provided in a recess of the stem housing 10b, and the first opening 11 is provided on the side of the fluid housing 13, and the first opening 11 can be connected to a second opening 21 on the side or in the lateral direction of the hollow flow path of the stem 20b.

Preferably, an upper end protrusion 25 provided on the upper part of the stem 20b on the inner circumferential surface 12 fits into a hole 15 in the lid 14 of the stem accommodating portion 10b, thereby locking the stem 20b and the stem accommodating portion 10b. After the locking state is achieved, the upper end protrusion 25b serves as the axis of rotation for the stem, allowing the protrusions 36, 36, 37, 37 on the inner circumferential surface 12 and the outer circumferential surface 22 to rotate in close contact with and slide against the inner circumferential surface 12, thereby reducing liquid leakage.

[0114] 3. Excrement collection device according to this embodiment This embodiment comprises a medical part according to the other embodiments described above and a waste collection bag (preferably a waste collection bag that collects waste from a stoma), and the waste collection bag 500 has a medical part 1 for discharging waste, and the attachment portion of the medical part 1 is attached to the outlet of the storage device, making it possible to provide a waste collection device.

As shown in FIG. 15, the excrement collection appliance 300 according to one embodiment includes a medical component 1 and an excrement collection bag 501 for collecting excrement from a stoma. As shown in FIG. 15, the rotary valve device 1 has a sealing surface involved in the valve opening and closing mechanism, and the flow rate of excrement can be easily adjusted by rotating the grip, allowing or preventing the discharge of excrement contained in the excrement collection bag 501. This reduces leakage after and during use. For example, excrement can be easily discharged, and excrement discharged from the rotary valve device 1 can be easily and appropriately discharged to a desired location. The "excrement collection bag for collecting excrement from a stoma" may also be a "leg bag."

[0118] The waste collection bag 501 is formed into a sealed bag using plastic film. A base plate 502 is provided on the top of the waste collection appliance 500.

[11] above. [Example]

[0124] The effects of the present invention will be specifically described below with reference to examples, etc. However, the scope of the present invention is not limited to the examples described in this specification.

[0125] <Production Example 1> To form the medical part (the mouthpiece of Example 1), a mold (circumferential protrusions 31, 31 surrounding the four sides of the opening and linear protrusions 32, 32) corresponding to the medical part of this first embodiment (FIGS. 1 to 10) was molded and manufactured by injection molding using a thermoplastic resin. The mouthpiece of Comparative Example 1 was manufactured by injection molding using a thermoplastic resin in the same manner as the mouthpiece of Example 1, except that it did not have the peripheral protrusions 31, 31 surrounding the four sides of the opening and the linear protrusions 32, 32. Polyethylene and polypropylene were used as the thermoplastic resins.

[0126] <Mouth of Example 1> The mouthpiece of Example 1 has a configuration as shown in FIGS. The mouthpiece of Example 1 has one circumferential protrusion extending downward from the first opening in the stem housing, one circumferential protrusion extending upward from the first opening, and two linear protrusions on either side of the first opening. The first and second openings are rectangular in shape. The length of the stem is 40 mm. The outer diameter of the stem is 10 mm. The inner diameter of the stem (diameter of the hollow flow path) is 7 mm. The height of the seal structure portion (opposing surfaces where the outer and inner surfaces overlap) is 15 mm. The width of the mounting portion is 9 mm, the height of the tubular portion is 35 mm, and the height of the discharge portion is 6 mm. The height of the peripheral surface formed by the outer peripheral surface of the stem and the inner peripheral surface of the stem accommodating portion is 15 mm. The height of the first and second openings is 4 to 6 mm, the opening angle of the first and second openings is 80°, and when rotated left and right, the first and second openings are in the same position up and down and left and right, and overlap with the same shape and size. The gap between the inner peripheral surface of the stem receiving portion and the outer peripheral surface of the stem is 0.2 mm. The lower circumferential protrusion is located 1 mm from the lower end (starting point) of the first and second openings, and the upper circumferential protrusion is located 1 mm from the upper end (starting point) of the first and second openings, for a total of two. There are two linear protrusions in total: one located 140° to the right of the first opening and the other located 140° to the left of the opening. The total length of the linear protrusions is the same as the total length of the stem. The thickness (height) of these protrusions is 0.3 mm. The width (base) of these protrusions is 0.6 mm. These protrusions are within the range of the seal structure.

[0127] <Mouthpiece of Comparative Example 1> It has the same shape as the mouthpiece of Example 1, except that it does not have the circumferential protrusions and linear protrusions of Example 1, and the outer and inner surfaces are sealed surfaces that are tightly attached.

[0128] [Evaluation of internal and external leakage] The rotary valve was closed, and as shown in FIG. 16, red ink was poured into the fluid reservoir provided in the first molded product (transparent), and left to stand for 30 minutes. The rotary valve spout of Example 1 had a water-stopping effect along the protruding structures provided below and to the sides of the opening, and no internal or external leakage occurred. On the other hand, the rotary valve spout of Comparative Example 1, which did not have a protruding structure, experienced internal or external leakage. In the case of internal leakage evaluation, if the watertight effect was not obtained and red ink was visible inside the core (stem) below the sealing surface, it was rated as "×: Fail", and if the watertight effect was obtained and no red ink was visible inside the core (stem) below the bottom end of the sealing surface, it was rated as "○: Pass". In the case of external leakage evaluation, if the watertight effect was not obtained and irregular red ink patterns were observed on the sealing surface when red ink flowed from the fluid storage section onto the sealing surface on the outside of the core (stem), it was judged as "×: Fail." If the watertight effect was obtained and irregular red ink patterns were not observed on the entire seat surface, it was judged as "○: Pass."
