Description

[Technical Field]

[0001] The present invention relates to medical components, and more particularly to a medical component usable in an excrement collection device for temporarily storing excrement, discharged fluids, gas, exudates, secretions, etc. (hereinafter collectively referred to as "excrement"; the same applies hereinafter) excreted from an excretory opening created in the human body, as well as an excrement collection device equipped with such a medical component. [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 have a pouch attached to the stoma that can 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 a pouch attached around the opening or wound to handle waste discharged by drainage or other means.

[0003] Furthermore, waste collection bags such as pouches and leg bags are equipped with a spout, which is a medical component, and this spout is used to discharge the waste accumulated in the waste collection bag to the outside. The most commonly used spouts are cap-type valves, which close or open the discharge of waste by inserting or removing an insert cap into a tubular discharge port, and rotary valves, which close or open the discharge of waste by a rotary cock valve equipped at the discharge port.

[0004] As an example of a spout having a cap-type valve, Figures 2 and 3 of Patent Document 1 disclose a spout 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 device having a rotary valve, FIG. 1 of Patent Document 2 discloses a device having 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.

The above-mentioned valve is a valve composed of multiple surfaces, and the multiple surfaces may be arranged in positions that are approximately on the same plane, or may be arranged at an angle toward either the inflow direction or the discharge direction in the flow path. The above-mentioned multiple surfaces may be comprised of at least a first surface and a second surface. When an external force is applied to the end of the line segment, the valve described above may open in an outward direction different from the direction of the applied force, forming an opening shaped like an arc. The valve may be one or more types selected from a leakage prevention valve for excrement, a force-operated on-off valve for excrement, and an excrement amount control valve.

[0018] 1. Background and Overview of the Invention

[0019] 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 (such as a stoma appliance or leg bag) is used to collect the excrement discharged from the stoma. Generally, a medical device is connected to the outlet of the waste collection bag for discharging the excrement, and the device is equipped with a valve or the like for controlling or regulating the flow of excrement. In addition, people with openings or wounds on the surface of their body due to other diseases may also have a discharge channel or waste bag for treating the excrement discharged by drainage or the like. The medical parts in the present invention are not particularly limited, but examples thereof include a mouthpiece that can be used in an excrement collection device for temporarily collecting excrement, discharged fluid, gas, exudate, secretion, etc. excreted from an excretory opening created in the human body, and the mouthpiece may be a medical mouthpiece.

[0020] In the medical field or related fields, there is a need for a valve that can allow, block, or restrict, or control or regulate, the flow of fluids such as bodily waste with a simple operation.

[0021] Furthermore, when using a waste collection appliance, a cap-type valve or a rotary valve is generally used to prevent waste from leaking from the tip of the outlet of the medical component provided in the waste collection appliance and to allow waste to be discharged as needed. In the case of ileostomy appliances, medical components equipped with a cap-type valve made of elastomer resin are often used. In the case of urostomy appliances, medical components equipped with a rotary valve and a cap are often used.

[0022] With conventional cap-type valves, users typically block the flow of waste by firmly pressing down on the discharge channel with their fingers or by lifting the tip of the medical component upward to bend the discharge channel, then remove the cap from the device's discharge port, point the discharge port toward a waste disposal location, and discharge the waste through the discharge port. Furthermore, in recent years, cap-type valves have tended to have larger inner diameters (approximately 10 mm to 25 mm) of the discharge channel or outlet of the medical component to prevent waste from clogging the channel or outlet. However, with cap-type valves, if the inner diameter of the discharge channel exceeds the size of the user's finger or if the pressure applied by the finger is weak, gaps are likely to form in the discharge channel, making it difficult to block the flow of waste and adjust the flow rate. Furthermore, when the discharge port of a medical component with the cap removed is pointed downward, waste may not be accurately discharged into the intended waste disposal location, resulting in the waste being scattered around the disposal location. For this reason, when a cap-type valve is used, it is often difficult to say that the user can easily discharge excrement (especially adjust the flow rate of excrement).

[0023] Conventional rotary valves are often constructed by combining multiple hard molded parts, which makes it easy for gaps to form between the parts, resulting in problems with sealing, such as preventing fluid leakage, even when the valve is not rotating. Furthermore, the valve is often located far from the human eye and is difficult to see, but with rotary valves, it is necessary to check the position of the rotation grip, the direction of rotation, and the position where the rotation is stopped when rotating the valve. For this reason, when rotary valves are used, it is often difficult to say that the user can easily discharge excrement (especially the rotation operation).

[0024] Therefore, the inventors have conducted extensive research into valves that allow for easy discharge of excrement, and have newly discovered that it is possible to provide a flow control component or medical component, and excrement collection device, that includes a novel valve mechanism that can allow or restrict the flow of fluid with a simple operation within a flow path provided inside a medical component, such as a mouthpiece. Furthermore, the valve of this technology can also have a configuration that can suppress leakage of excrement.

[0025] The present technology can provide a flow control component that includes a valve in a flow path through which a fluid flows, the valve having one or more line segments in a planar view from either side of the flow path direction, and the line segments can be opened and closed by controlling the applied force. The present technology also provides a valve including a flow path communicating with a waste collection bag, the valve being provided in the flow path and having one or more line segments in a plan view from one side of the flow path direction; It is possible to provide a medical component that can be attached to a waste collection bag, the medical component comprising: a line segment that can be opened and closed by controlling the applied force. Furthermore, the present technology can also provide a waste collection device that includes a waste collection bag for containing waste and the above-mentioned medical component, the waste collection bag having an outlet through which the waste is discharged, and the attachment portion of the medical component being attached to the outlet.

[0026] The present technology can provide an adjustment mechanism (e.g., a fluid discharge restriction mechanism or a flow rate adjustment mechanism) that can allow, restrict, or adjust the flow of fluid, and / or a simple operation for discharging excrement. The present technology can easily prevent fluid leakage from medical components. By not applying force to the medical component, no opening is formed in the flow path, and fluid is not discharged to the outside. By applying force to the medical component, an opening is formed in the flow path, and fluid can be discharged from the opening to the outside through the outlet of the oral device. Furthermore, by adjusting the force applied to the medical component, the size of the opening formed in the flow path can be adjusted, thereby adjusting the amount of fluid discharged to the outside.

[0027] According to the present technology, it is possible to provide a medical component and a waste collection device that allows easy discharge of waste when using the waste collection device. According to the present technology, it is possible to prevent leakage of waste even when using the waste collection device. Furthermore, according to the present technology, it is possible to prevent leakage of waste even when wearing the waste collection device and to easily discharge waste. Furthermore, conventionally, when the viscosity of excrement from a small intestinal stoma (ileostomy) or a urinary stoma (urostomy) is low, there is a risk of the excrement scattering unless the flow rate is adjusted when the excrement is discharged from a waste collection bag (stoma appliance, leg bag, etc.). However, with this technology, even when the viscosity of the excrement is low, leakage of the excrement can be suppressed, which has the advantage of making the excrement discharge process easier.

[0028] The present technology will be described in detail below, but the present technology is not particularly limited to the following exemplary embodiments.

[0029] 2. Medical parts according to this embodiment An example of the configuration of a medical component according to one embodiment of the present invention will be described with reference to FIGS. 1 to 8, but the present invention is not particularly limited to the configuration and description of one embodiment, or to these drawings and symbols.

[0030] The medical component 1 according to this embodiment will be described below with reference to Fig. 1, a side view, Fig. 2, a top view, Fig. 3, a bottom view, Fig. 4A, a cross-sectional view, Fig. 5, a view showing the opening and closing of the discharge flow path, and Fig. 8, which shows an example of a waste collection device equipped with the medical component of this first embodiment. The medical component 1 may also be a medical component, a mouthpiece 10.

[0031] The medical component 1 according to this embodiment is preferably a medical component that is attached to a waste collection bag 101. The medical component 1 preferably includes a flow path 2 that communicates with the waste collection bag 101, and a valve 3 that is provided within the flow path 2 and has one or more line segments in a plan view from either side of the flow path direction. Furthermore, the line segment 4 is preferably configured to be openable and closable by applying force control. Furthermore, it is more preferable that the flow path 2 is connected to the discharge port of the waste collection bag 101. It is more preferable that the flow path 2 is within a flow path that can discharge waste into the inside of the medical component 1. The flow path direction is also referred to as the Z-axis direction. In this embodiment, the waste may be replaced with a fluid (preferably a liquid), and the waste is preferably low-viscosity waste as described above.

[0032] This embodiment can provide a medical component 1 that is attached to a waste collection bag 101 and includes a flow path 2 that communicates with the waste collection bag 101, and a valve 3 that is provided within the flow path 2 and has one or more line segments 4 in a plan view from either side of the flow path direction, and the line segments 4 can be opened and closed by controlling the applied force. In a preferred embodiment, the medical component 1 is preferably configured to include an attachment portion 20 that is attached to the waste collection bag 101, a flexible tubular portion that includes the above-mentioned valve 3, and a discharge portion that discharges the waste to the outside. The waste collection bag 101 is not particularly limited, but examples include a pouch that stores waste from a stoma and a leg bag.

[0033] Generally, planar view refers to viewing an object as a plane from a certain direction using orthographic projection. Orthographic projection is said to be one of the methods for representing a three-dimensional drawing on a plane, and orthographic projection is also called planar view. In this specification, when viewing valves in a flow path in a plan view, it is preferable to view one valve in a plan view from the flow path direction (upper or lower). For example, in a hollow, approximately cylindrical medical component having a flow path in a direction approximately parallel to the body surface (Z-axis direction) when the excrement collection device is worn on the body, the upper and lower portions of one valve may be cut in a substantially horizontal direction (XY-axis direction) and one valve may be viewed in a plan view from above or below. Note that when the medical component is set so that the attachment part is on top and the discharge part is on the bottom, the direction of the attachment part of the medical component may be the upper direction, or the direction of the discharge part of the medical component may be the lower direction. Furthermore, the inflow direction of excrement from the medical component may be the upper direction, and the discharge direction of excrement from the medical component may be the lower direction.

[0034] The present embodiment will be described in detail below, but the present embodiment is not limited to this.

[0035] The oral device 10, which is the medical component 1, will be described below. As shown in FIG. 1, the spout 10 preferably includes a flow path 2 for discharging excrement from the excrement collection bag 101 inside the spout, and a valve 3 provided within the flow path. The flow path 2 is preferably configured to communicate with the excrement collection bag 101, and this communication configuration preferably includes, for example, a connection between the discharge port of the excrement collection bag 101 and an attachment portion of the flow path 2. The spout 10 preferably includes at least one valve 3. The valve 3 preferably has one or more line segments 4 in a plan view from either side of the flow path direction (Z-axis direction). For example, the valve 3 may have one line segment or two line segments in a cross shape (see FIGS. 2 and 3). The valve 3 is preferably a valve capable of suppressing the discharge of excrement. Furthermore, the valve 3 is preferably a valve that can be opened or closed by adjusting the force applied from outside or inside the spout, and the flow rate of excrement can also be adjusted by adjusting the force applied (see FIG. 5). From the standpoint of function, the valve 3 may be, for example, a discharge suppression valve, a valve for suppressing leakage of excrement, a force-operated opening / closing valve, or a valve for controlling the amount of excrement excreted, and may be a valve that performs any of these functions, from which one or more types may be selected.

[0036] The appliance 10 is preferably hollow and generally cylindrical, more preferably vertically elongated. The appliance 10 more preferably has a flow path 2 inside the generally cylindrical shape for discharging waste from the stoma. Waste flowing from the waste collection bag 101 into the appliance 10 passes through the attachment part 20 and the inner flow path, and can be discharged to the outside from the discharge part 30. The medical component 1 is preferably flexible, and is preferably made of a flexible resin.

[0037] The spout 10 preferably comprises an attachment portion 20, a tubular portion 30, and a discharge portion 40, and more preferably these are arranged in the order of attachment portion 20, tubular portion 30, and discharge portion 40 from top to bottom. The spout 10 is preferably an integrally molded product in which these portions are molded from the same resin material. Furthermore, the spout 10 may further be provided with a cap portion, or may be an integrally molded product in which the cap portion is molded integrally with the cap 50 described below, and these portions are preferably made of the same resin material.

[0038] The attachment portion 20 is preferably a portion that is attached to the waste collection bag or its outlet. The tubular portion 30 is preferably a portion that includes at least one valve 3 present in a flow path. The discharge portion 40 is preferably a portion that discharges waste to the outside. Each of these portions preferably has a flow path inside, and by connecting these flow paths, a flow path that can discharge waste from the stoma to the outside can be formed. Furthermore, one or more of the portions selected from the attachment portion 20, the tubular portion 30, and the discharge portion 40 may have one or more valves 3 inside, and at least one of the portions (preferably the tubular portion 30) may have one or more valves 3 inside.

[0039] In a preferred aspect of this embodiment, the spout 10 preferably comprises an attachment portion 20 that is attached to the excrement collection bag described above, a flexible tubular portion 30 that includes the valve 3 described above, and a discharge portion 40 that discharges to the outside.

[0040] 5, the valve 3 preferably has a mechanism for suppressing excrement discharge by not applying force from the outside (e.g., the outer periphery) or inside (e.g., the flow path side) of the device 10, and / or is configured so that the excrement discharge suppression mechanism can be released and the discharge amount can be adjusted by applying force from the outside (e.g., the outer periphery) or inside (e.g., the flow path side) of the device 10. The strength of the force can be the strength of the pinching force between multiple fingers, such as the thumb and index finger, so the excrement discharge operation can be done with a simple operation.

[0041] In a more preferred embodiment, the valve 3 is configured to suppress the flow in the flow path 2 when the line segment 4 is maintained in a planar view, and to open the flow path 2 when the line segment 4 is pressurized in a planar view. Furthermore, in a more preferred embodiment, the valve 3 is configured so that an opening 5 through which excrement can be discharged is not formed when the line segment 4 is maintained, and so that an opening 5 through which excrement can be discharged is formed when the line segment 4 is pressurized. This makes it easy to control whether to suppress or allow excrement discharge. Furthermore, because such control is easy, the user can discharge excrement after determining the external discharge destination, and further, the discharge of excrement to the outside can be easily controlled by adjusting the applied force. The discharge amount is preferably the flow rate of excrement.

[0042] In a more preferred embodiment, the valve 3 is preferably configured so that it can be opened and closed by controlling the application of force from the outside to the ends (preferably both ends) of the line segment 4, for example, by a finger, and / or by controlling the application of force from the inside to the outside of the line segment 4, for example, by a connector inserted from the outside in the flow path direction. The valve 3 is more preferably configured so that it forms an opening 5 through which excrement can be discharged when force is applied. The valve 3 is preferably configured so that the opening 5 through which excrement can be discharged is opened when force is applied from the outside to the ends (preferably both ends) of the line segment 4 in the central axis direction and / or when force is applied from the inside to the outside of the line segment 4. The valve 3 is preferably configured so that the opening 5 through which excrement can be discharged is not opened when no force is applied from the outside and / or the inside. Specifically, as shown in FIG. 5 , the line segment 4 is preferably configured to be openable and closable by force control. The line segment 4 preferably passes through approximately the center of the inner diameter of the flow path 2. Furthermore, it is more preferable that when an external force is applied to the end of the line segment 4, the line segment 4 opens in an outward direction different from the direction of the applied force, forming the opening 5, and the different outward direction is preferably perpendicular to the direction of the applied force. The different outward direction is more preferably a direction directed outward from the approximate center of the line segment 4 or the valve 3. The shape of the opening 5 thus formed is preferably a shape surrounded by an arc, more preferably a shape surrounded by two arcs. A more preferable shape of the opening 5 is preferably an axisymmetric shape, with two arcs meeting at their chords, and more preferably the chords being on the line segment before opening.

[0043] The aforementioned "force from the outside" is not particularly limited, but may be, for example, a means capable of pressing the outer portion of the oral device 10 (preferably the tubular portion 30). More specific examples include the fingers of a human being, such as a wearer or caregiver, or a flow control mechanism such as a tube, whereby a force is applied to the line segment from the outside. The aforementioned "force from the inside" is not particularly limited, but may be, for example, a means capable of opening the line segment from within the flow path. More specific examples include, for example, a medical connector such as a connecting tube or tube connector, whose outer diameter is smaller than the inner diameter of the flow path or the length of the line segment. For example, the tip of the connector is inserted into the flow path from the outlet of the discharge portion 40 and further inserted along the flow path direction, and a force from the inside is applied to the line segment when inserted into the line segment. One or more types selected from these may be used.

[0044] As shown in Figures 2 and 3, when the valve 3 is viewed from above in either one of the flow path directions, line segment 4 is preferably located on a plane in the planar view. On the plane in the planar view, line segment 4 is preferably located, for example, on the maximum major axis, maximum minor axis, diagonal, diameter, X-axis, or Y-axis, more preferably on the diameter or Y-axis. The position of the center of line segment 4 is preferably approximately the same as or the same as the position of the intersection or center of the plane in the planar view. Line segment 4 is more preferably located on the diameter of the plane in the planar view or on the Y-axis and / or X-axis passing through approximately the center of the plane in the planar view. Furthermore, the length of line segment 4 is preferably the same as or approximately the same as or shorter than the length of the maximum major axis, maximum minor axis, diagonal, diameter, or the like of the plane in the planar view. Furthermore, of the single or multiple line segments, at least one line segment may be arranged in a direction approximately perpendicular to the body surface (Y-axis direction) and / or perpendicular to the X-X' line. Furthermore, when a spout is provided on the excretion storage appliance described below, at least one line segment is preferably arranged in a direction approximately perpendicular to the plane of the pouch in terms of its position relative to the pouch, and in the case of cross-shaped line segments, it is preferable that one line segment is arranged in a direction approximately perpendicular to the plane of the pouch and the other line segments are arranged in a direction approximately horizontal to the plane of the pouch. Furthermore, it is more preferable that at least one line segment passes through approximately the center of the surface in a planar view.

[0045] When no force is applied to line segment 4 and the line segment is maintained, opening 5 is not formed and valve 3 is in an unopened state in plan view at this time, which prevents excrement from flowing downstream of valve 3. This also makes it possible to prevent excrement leakage. In this way, by having line segment 4 in plan view, valve 3 can have a mechanism for suppressing excrement discharge.

[0046] When line segment 4 is in an applied state, opening 5 is formed, and at this time, valve 3 is in an open state in a planar view, thereby allowing excrement to flow downstream of valve 3. Furthermore, adjusting the strength of the force applied to the line segment adjusts the size of the opening, so it is also possible to adjust the increase or decrease in the flow rate of excrement by adjusting the strength of the force. For example, when a stronger force is applied, the opening becomes larger and the flow rate of excrement increases, and the reverse (weak-small-decreased) is also possible. In this way, by having line segment 4 in a planar view, valve 3 can have a mechanism for adjusting the flow rate of excrement. A valve having this line segment is preferably a flexible valve, and more preferably a valve made of flexible resin.

[0047] Furthermore, the line segment 4 is preferably configured so that when the applied force is removed or the applied force is released, the opening 5 of the valve 3 in a plan view returns to the line segment 4 (unopened state). Furthermore, depending on whether or not a force is applied, the line segment 4 can be maintained or the opening 5 can be formed from the line segment 4, and the flow of fluid can be repeatedly blocked or permitted by repeatedly applying and not applying force. A valve having such a line segment is preferably a flexible valve, and more preferably a valve made of flexible resin.

[0048] As a preferred example, when the line segment 4 in the flow path 2 is in a state where a force is applied, the line segment 4 in a plan view on a surface in a plan view opens outward (for example, in the X-axis direction), and an opening 5 can be formed on the surface. The formation of the opening releases the excrement discharge suppression mechanism. This release allows the flow of excrement from the excrement collection bag into the medical component 1. This allows the excrement to pass through the opening 5 and then be discharged from the discharge port of the discharge unit 40. In addition, as a preferred example, when line segment 4 in path 2 is in a state where no force is applied, line segment 4 in plan view on the surface in plan view does not open outward (e.g., in the X-axis direction), and opening 5 is not formed on the surface. By not forming an opening, the excrement discharge suppression mechanism is maintained. This maintenance blocks the flow of excrement from the excrement collection bag into spout 10. As a result, the excrement cannot pass through opening 5, and is not discharged from the discharge outlet of discharge unit 40.

[0049] The shape of the opening 5 in plan view is not particularly limited, but is preferably approximately circular (approximately elliptical, approximately perfect circle). A more preferred shape of the opening 5 is approximately elliptical, for example, a rugby ball shape, which is an axisymmetric shape with two arcs joined at the chords. The ratio of the minor axis to the major axis of the elliptical shape in the open state can be adjusted by applying force, and examples of the ratio include a minor axis of 1 to a major axis of 1 to 10, a major axis of 2 to 6, or a major axis of 3 to 5 (see FIG. 5).

[0050] The length of line segment 4 is not particularly limited, but is preferably approximately equal to or less than the inner diameter of the inner flow path 2, and from the viewpoint of processing, is more preferably slightly shorter than the inner diameter of flow path 2. The ratio of [length of line segment / inner diameter of inner flow path] (the length of line segment 4 when the inner diameter of the inner flow path is 1) has a preferred lower limit of preferably 0.6 or more, more preferably 0.7 or more, even more preferably 0.8 or more, more preferably 0.9 or 0.95 or more, and a more preferred upper limit of preferably 1 or less or 0.98 or less.

[0051] As shown in Figures 2 and 4, the valve 3 is preferably a valve composed of multiple surfaces. As shown in Figure 4, it is preferable that the multiple surfaces are arranged in positions that are approximately on the same plane, or in positions that are inclined upward or downward.

[0052] Furthermore, the above-mentioned multiple surfaces are preferably composed of at least two surfaces, and more preferably composed of at least a first surface and a second surface. For example, as shown in Fig. 2A, there is a valve 3 composed of two surfaces, a first surface 3a and a second surface 3b, and as shown in Fig. 2B, there is a valve 3 composed of four surfaces, first surfaces 3a1, 3a2, and second surfaces 3b1, 3b2. Of these, a valve 3 composed of two surfaces, a first surface 3a and a second surface 3b, is preferred.

[0053] For example, one notch may be provided on one surface to form two surfaces, and this notch may be a line segment. For example, the overlapping or contacting portion of the ends of multiple surfaces may be a line segment. In this way, it is preferable that the notch on one surface or the overlapping portion of different surfaces appears as a line segment in a planar view. It is preferable that there be one or more line segments on the plane in a planar view.

[0054] 4A to 4C are cross-sectional views taken along line XX' passing through the center of the inner diameter of the mouthpiece in FIG. 2A, and are also vertical (Z-axis) cross-sectional views. As shown in FIG. 4A, it is preferable that a plurality of surfaces are arranged in positions that are substantially on the same plane, and a plane having a line segment in plan view can also be formed from planes on the same plane. 4B, it is preferable that the plurality of surfaces are arranged at an inclination in the discharge direction. It is also preferable that the plurality of surfaces are arranged at a downward inclination, and the downward inclined surfaces can form a plane having a line segment in a plan view. 4C, it is preferable that the plurality of surfaces are arranged at positions inclined toward the inflow direction. It is also preferable that the plurality of surfaces are arranged at positions inclined upward, and the upper inclined surfaces can form a plane having a line segment in a plan view. Also, Figure 4 may be a vertical (Z-axis) cross-sectional view passing through the center of the inner diameter of the mouthpiece in Figure 2B in the X-axis direction, and in this case the cross-section may have the same cross-sectional structure as Figures 4A to 4C. Furthermore, the thickness of the multiple surfaces (thickness in the Z-axis direction) is not particularly limited, but a suitable lower limit is preferably 0.5 mm or more, more preferably 0.8 mm or more, and a suitable upper limit is more preferably 5 mm or less, even more preferably 3 mm or less, and more preferably 2 mm or less.

[0055] In a preferred aspect of this embodiment, the valve having a preferred line segment is a valve composed of multiple surfaces, and the multiple surfaces are preferably arranged in positions on approximately the same plane, or in positions that are inclined upward or in positions that are inclined downward, and more preferably in positions on approximately the same plane, or in positions that are inclined upward. Note that the upward inclination may be an inclination toward the inflow direction or an inclination toward the attachment portion, and the downward inclination may be an inclination toward the discharge direction or an inclination toward the discharge portion, and the upward inclination or the downward inclination may be an inclined surface connected to the inner wall of the flow path. The line segments are more preferably vertical or horizontal line segments (straight line segments) in a plan view, or vertical and horizontal line segments (cross-shaped line segments), and in the case of cross-shaped line segments, the line segments preferably intersect at approximately right angles. The shape of the line segments is not particularly limited, but straight line segments are preferred. The vertical direction is also referred to as the Y-axis direction, and the horizontal direction is also referred to as the X-axis direction. The vertical direction (Y-axis direction) or horizontal direction (X-axis direction) may be approximately perpendicular to the plane of the excrement collection bag when the spout is attached, or a direction perpendicular to this approximately perpendicular direction. A more suitable valve is one that is composed of two surfaces and has a line segment in the vertical direction (Y-axis direction) when viewed in a plane, and it is even more preferable that the two surfaces are positioned on approximately the same plane, or are positioned at an upward incline.

[0056] Furthermore, it is preferable that the valve 3 has one or more (e.g., two or three) line segments in a plan view from either one of the flow path directions within the flow path for discharging excrement, and the number of line segments is more preferably one or two, and even more preferably one (see Figures 2 to 4).

Examples of a rounded polygonal shape include a polygon that is vertically symmetrical and / or bilaterally symmetrical with rounded corners, and more specific examples include a horizontally elongated rounded square, a horizontally elongated rounded polygon that is close to an ellipse, etc., and one or more types selected from these may be used.

[0061] From the viewpoint of attaching the pouch, the cross-sectional shape of the attachment part 20 in the horizontal direction is preferably a substantially elliptical shape like a rugby ball. The maximum major axis of the outer periphery of the attachment part is preferably 1 to 10, more preferably 1 to 5, and even more preferably 2 to 5, when the inner diameter of the mouthpiece is 1. The maximum minor axis of the outer periphery of the attachment part is preferably 1 to 5, more preferably 1 to 3, and even more preferably 1 to 2, when the inner diameter of the mouthpiece is 1.

[0062] From the viewpoint of ease of operation, the horizontal cross-sectional shape of the tubular portion 30 is preferably approximately circular, such as approximately elliptical or approximately perfect circle, and is more preferably approximately perfect circle. The outer diameter of the tubular portion is preferably 1 to 2, more preferably 1 to 1.5, and even more preferably 1.0 to 1.4, where the inner diameter of the nozzle is 1. The outer diameter may be any of the diameter, maximum minor axis, or maximum minor axis. The shape of the valve 3 in a plan view is preferably the same as the shape of the flow path 2 of the tubular portion 30 in a plan view. The position of the valve 3 in the tubular portion 30 is not particularly limited, but may be near the middle between the attachment portion 20 and the discharge portion 40, closer to the attachment portion 20 than this middle, or closer to the discharge portion 40 than this middle. The position of the valve 3 is preferably 0.1 to 0.8, more preferably 0.2 to 0.7, where the distance from the lower end of the attachment portion 20 to the upper end of the discharge portion 40 (also referred to as the height of the tubular portion 30) is 1. The lower end of the attachment portion 20 and the upper end of the discharge portion 40 are in a positional relationship when the spout is positioned with the attachment portion at the top and the discharge portion at the bottom. The lower end of the attachment portion 20 may be the end of the attachment portion that contacts the tubular portion 30 and / or the end of the attachment portion that is closest to the discharge portion 40. The upper end of the discharge portion 40 may be the end of the discharge portion that contacts the tubular portion 30 and / or the end of the discharge portion that is closest to the attachment portion 20.

[0064] The fitting used in this embodiment may be a medical part, and is preferably a medical part used for one or more types selected from, for example, an ostomy appliance pouch, a drainage pouch, a feces bag, a urine collection bag, a urine collection bag, a leg bag, etc. In the case of a fitting used as a medical part, it may be a 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 used in this embodiment for discharging the accumulated waste to the outside.

[0065] The above-mentioned spout is preferably one that is attached to a waste collection bag, and examples of the waste collection bag include, but are not limited to, pouches, bags, etc. Among these, the spout is preferably one that is attached to a pouch or bag that contains waste, but the use of the pouch is not particularly limited, and examples include a stoma (e.g., colostomy, ileostomy, urostomy, etc.), a drain, etc., from which one or more types can be selected. Furthermore, the above-mentioned mouthpiece is more preferably a mouthpiece for a waste collection device used for low-viscosity waste, and the low-viscosity waste collection device is preferably one or more types selected from, for example, devices for ileostomy and urostomy.

[0066] As shown in FIG. 7 , a cap 50 for sealing the discharge port of the oral device 10, which discharges excrement to the outside, may be provided on the oral device 10, and the cap 50 can further prevent excrement leakage. For example, from the viewpoint of further preventing excrement leakage, the oral device 10 preferably further includes a cap 50 that can be inserted into and contacts the opening of the discharge port of the oral device 10, and the cap may have pleats. In a preferred aspect of this embodiment, the oral device 10 is preferably an integrally molded product with the cap 50. Furthermore, the oral device 10 may be an integrally molded product with the cap 50 and a connecting portion for connecting to the cap. The connecting portion may be connected to any portion of the oral device 10, for example, to the outside of the area between the tubular portion 30 and the discharge portion 40. The medical component may include an integrally molded product in which the oral device 10 and the cap 50 are integrally molded. The mouthpiece 10 and the cap 50 are preferably molded from the same resin material, and the resin material is more preferably a flexible resin material.

[0067] The above-described medical components can be molded using a resin material by known molding methods such as injection molding or mold molding. The spout can be molded as a valve without lines, and then a jig can be inserted into the flow path to create a line by making a cut or the like in the valve. The spout used in this embodiment has the advantage that it can be manufactured using such a simple molding method. Examples of resin materials that can be used include ultraviolet-curable resin and thermoplastic elastomer resin. In this embodiment, flexible resin is preferred from the viewpoint of adjusting the force applied by fingers, etc. The flexible resin is not particularly limited, and for example, its durometer hardness is preferably 50 to 80, and more preferably 65 to 70 in terms of Duro hardness A (JIS6253).

[0068] 3. Excrement collection device according to this embodiment This embodiment can provide a waste collection device that includes a medical part according to the other embodiments described above and a waste collection bag (preferably a pouch that contains waste from a stoma) in which waste is collected, the waste collection bag having an outlet through which the waste is discharged, and the attachment portion of the medical part is attached to the outlet.

[0069] Examples of the excrement collection device 100 include an ostomy device, a drainage pouch, a fecal bag, a urine collection bag, a urine collection bag, and a leg bag, and one or more of these can be selected.

[0070] An excrement collection device according to one embodiment of the present invention will be described with reference to Fig. 8. Fig. 8 is a front view showing an example of the configuration of an excrement collection device 100 according to one embodiment of the present invention.

[0071] The excrement collection appliance 100 shown in FIG. 8 is preferably an ostomy appliance, which is one example. As shown in FIG. 8, the excrement collection appliance 100 according to one embodiment includes an oral appliance 10, which is a medical component 1, and a pouch 101 for storing excrement from a stoma. As shown in FIG. 8, the oral appliance 10 can suppress the discharge of excrement stored in the pouch 101 when no pressure is applied with a finger or the like, and can allow the discharge of excrement stored in the pouch 101 when pressure is applied with a finger or the like. Furthermore, the amount of excrement discharged can be easily adjusted by varying the strength of pressure applied with a finger or the like. This simplifies the excrement discharge process, and excrement discharged from the oral appliance 10 can be easily and appropriately discharged to a desired location, for example. The "pouch for storing excrement from a stoma" may also be a "leg bag."

[0072] The pouch 101 is formed into a sealed bag shape using plastic film. A base plate 102 is provided on the top of the waste collection appliance 100. The pouch 101 is attached to the patient's stoma using the adhesive layer of the base plate 102. The waste passes through holes 103 in the base plate 102 and is discharged into the pouch 101.

[0073] The pouch 101 has an outlet through which excrement is discharged, and the outlet is connected to the attachment part 20 of the mouthpiece 10.

[0074] When no force is applied to the mouthpiece 10, the discharge suppression mechanism of the valve 3 is activated and no opening 5 is formed in the valve 3, keeping it closed. Therefore, even if the excrement contained in the pouch 101 passes through the discharge outlet of the pouch 101 and flows into the flow path of the attachment part 20 of the mouthpiece 10, which is the medical part 1, it cannot pass through the valve 3, which is in a closed state within the flow path, and is not discharged from the discharge part 40. When the discharge suppression mechanism of the valve 3 is released by applying force to the spout 10 and an opening 5 is formed in the valve 3, the excrement contained in the pouch 101 passes through the discharge port of the pouch 101, flows into the flow path of the attachment part 20 of the spout 10, which is the medical part 1, passes through the opening 5 of the valve 3 inside the flow path, and is discharged from the discharge part 40. Then, when the force applied to the spout 10 is removed, the valve 3 closes again and the excrement is not discharged from the discharge part 40.

[0075] Therefore, the excrement collection apparatus 100 allows the wearer to easily discharge excrement while wearing it.

[Example]

[0077] 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.

[0078] <Production Example 1> A 3D printer (RAISE 3D, manufactured by Nippon Printer Co., Ltd.) was used to form the medical parts (the devices in Examples 1 and 2). HP Filament Super Flexible, manufactured by Hotty Polymer Co., Ltd., was used as the resin material for forming the medical parts. This 3D printer can produce devices such as those shown in Figure 1, and can also produce devices that are integrally molded with a cap that can close the internal flow path of the discharge part, as shown in Figure 6. The valve fitting having one line in Example 1 was made by making a single incision (7.9 mm) slightly shorter than the inner diameter (8 mm) using a sharp blade from above in a membrane (approximately flush: 1 mm thick) located in a flow path inside (inner circumference) of a molded product made by a 3D printer, passing through the center of the inner circumference and perpendicular to the X-X' line. In addition, the valve fitting having a cross-shaped line in Example 2 was made by cutting a cross-shaped incision from above with a sharp blade into a membrane (approximately flush: 1 mm thick) inside a flow path inside (inner circumference) of the molded product, passing through the center of the inner circumference, with two incisions perpendicular to each other, and the length of each incision was 7.9 mm, slightly shorter than the inner diameter (8 mm). Although this resin material is not a resin material that is actually used (for example, ultraviolet curing resin or thermoplastic elastomer resin), it can provide the same effect as a resin material that is actually used. Furthermore, it is possible that a resin material that is actually used can provide a better effect. The resin material used was a flexible resin with a durometer hardness of 65 to 70 in JIS6253.

[0079] The spouts of Examples 1 and 2 are hollow, generally cylindrical flexible spouts with an internal flow path (see, for example, Figures 1, 2, 3A, 4A, 5, and 6). These generally cylindrical spouts are configured, in upright position, with an attachment part, a tubular part, and a discharge part arranged in this order from top to bottom. The tubular part of the device of Example 1 has a flow path for the fluid inside, and the flow path of this tubular part has a substantially identical plane perpendicular to the flow path direction, and on that plane there is one line segment when viewed from either side in the flow path direction. In the case of the device of Example 2, the flow path of the tubular part has a substantially identical plane perpendicular to the flow path direction, and on that plane there are two line segments in a cross shape when viewed from either side in the flow path direction, but other than that it is the same as the device of Example 1.

[0080] The vertical height of the hollow, approximately cylindrical shape of the spouts in Examples 1 and 2 was 50 mm, which was the same as the total length of the internal flow path. The diameter of the internal flow path of the spouts in Examples 1 and 2 was 8 mm. The length of the line segment when not pressed with a finger was 8 mm, and the opening was an oval shape like a rugby ball when pressed with a finger. By pressing hard, it could be deformed into an approximately perfect circle. Therefore, it is believed that the opening can have a major diameter of 1 to 10 when the minor diameter is 1. The horizontal cross section of the attachment part at the top of the fittings of Examples 1 and 2 was an oval shape like a rugby ball, and the diameter (longer diameter) of the outer periphery of the attachment part was 13 mm. The outer diameter of the tubular portion of each of the spouts in Examples 1 and 2 was 10 mm. The plane containing the line segment present in the internal flow path of the tubular portion was located at a position halfway along the entire length in the flow path direction. The outer diameter of the discharge part of the spouts in Examples 1 and 2 was 13 mm.

[0081] The valve of Example 1 has one line segment in a plan view from either side of the flow path direction within the flow path that exists inside and through which a fluid flows (see, for example, Figures 1, 2A, 3, 4A, and 5). The valve of Example 1 is composed of an upper mounting section, a central flexible tubular section, and a lower discharge section, and these sections have a substantially cylindrical flow path with approximately the same diameter within them, and somewhere in the middle section within this flow path is a substantially identical plane that is perpendicular to the flow path direction, and one line segment is on that plane.

[0082] The valve of Example 2 has two line segments in a plan view from either side of the flow path direction within the flow path that exists inside and through which the fluid flows (see, for example, Figures 1, 2B, 3, 4A, and 6). The valve of Example 2 is composed of an upper mounting section, a central flexible tubular section, and a lower discharge section, and these sections have a substantially cylindrical flow path with substantially the same diameter within them, and somewhere in the middle of this flow path, there is a substantially identical plane that is perpendicular to the flow path direction, and two line segments (cross-shaped) are on that plane.

[0083] The upper part of the valve in Examples 1 and 2 has a mounting part for mounting to the pouch. The outer periphery of the mounting part is oval like a rugby ball from above, and there is a hollow flow path in the center for discharging excrement, and this flow path is hollow and approximately cylindrical.

[0084] The center of the valve in Examples 1 and 2 has a flexible tubular portion. The flow path inside the flexible tubular portion has a first surface and a second surface that are arranged in a substantially coplanar position. By applying pressure to both ends of the line segment from the outside of the tubular portion with the thumb and index finger, an opening that allows fluid to flow to the discharge portion can be formed.

[0085] The opening in Example 1 is an oval shape like a rugby ball, and when external force is applied to both ends of the line segment, it opens in an outward direction different from the direction of the applied force, forming an opening shaped like an arc, and the shape surrounded by this arc is an elongated, approximately oval shape (see Figure 5).

[0086] When an external force is applied to both ends of one of the two line segments of the cross, the opening of Example 2 opens in an outward direction different from the direction of the applied force, forming an opening shaped like an elongated, approximately elliptical arc. When an external force is applied to both ends of the other line segment, the opening of Example 2 opens in an outward direction different from the direction of the applied force, forming an opening shaped like an elongated, approximately elliptical arc (see FIG. 6).

[0087] Furthermore, in both the mouthpiece of Example 1 and the mouthpiece of Example 2, when no force is applied to either end of the line segment from the outside (such as by removing the finger or not pressing with the finger), the state of the line segment is maintained and no opening is formed.

[0088] In Examples 1 and 2, a discharge part, into which a cap can be inserted, is provided below the valve and connected to the tubular part. The inner diameter of the tubular part and the inner diameter of the discharge part are approximately the same. The discharge part is hollow and approximately cylindrical, and its outer diameter is designed to be approximately 1.05 to 1.2 times the outer diameter of the tubular part.

[0089] <Measuring method for durometer A (JIS6253)> The durometer hardness A of one test piece is measured in accordance with JIS 6253. At this time, the measurement is performed in accordance with the shape and dimensions of the indenter and pressure plate of a type A durometer.

[0090] The resin material used in the valve of Example 1 was cut into a plate-shaped test piece, and the durometer A (JIS6253) of the test piece was in the range of 65-70.

[0091] The medical component was evaluated, and the results are shown in Table 1 below. For the capped valve-equipped mouthpiece of Comparative Example 1, a commercially available product having the same configuration as that of Patent Document 1 was obtained and used. For the capped rotary valve-equipped mouthpiece of Comparative Example 2, a commercially available product having the same configuration as that of Patent Document 2 was obtained and used.

[0092] [Table 1]

[0093] Regarding the function of suppressing discharge (leakage) within the flow path, the devices of Comparative Example 1 and Comparative Example 2 did not have any particular valve function within the flow path. On the other hand, in the devices of Example 1 and Example 2, by applying force from the outside to both ends of the line segment, the line segment opens in an outward direction perpendicular to the direction of applied force, forming an opening, allowing the passage of fluid through the opening and discharging the fluid, or, when no force is applied, the opening is closed and the surface on the same plane prevents the passage of fluid, preventing the fluid from being discharged.

[0094] The spout of Example 1 has one line segment, so force can be applied in one direction. On the other hand, the spout of Example 2 has two line segments, so there are two directions in which force can be applied when viewed in a plan view, which has the advantage that fluid can be discharged whether the tubular portion is pressed vertically or horizontally. The spout of Example 2 also has the advantage that, even though it is cross-shaped, it only opens in one direction depending on the direction of pressing.

[0095] Both the spouts of Example 1 and Example 2 passed the test in terms of functionality in permitting or preventing (leaking) discharge within the flow path, but the spout of Example 2 had a slightly weaker seal, possibly due to the cross-shaped cut, and some fluid seepage was observed. Therefore, from the perspective of functionality in permitting or preventing (leaking) discharge within the inner flow path, the spout of Example 1 has the advantage of being superior to the spout of Example 2.

[0096] In the devices of Examples 1 and 2, the size of the opening could be adjusted by adjusting the external finger pressure, thereby adjusting the amount of drained liquid. In Comparative Example 1, the cap was pulled out from the inner wall near the outlet, so the inner diameter of the flow path at the outlet could not be adjusted, making it difficult to adjust the amount of drained liquid. In Comparative Example 2, the amount of drained liquid could be easily adjusted by adjusting the rotation.

[0097] In the devices of Examples 1 and 2, the opening could be easily opened by applying finger pressure from the outside or by using a catheter or the like from the inside. In the devices of Examples 1 and 2, the device was aimed toward a waste disposal area, and then finger pressure was applied, allowing waste to be discharged in the direction of the disposal area. With the device of Comparative Example 1, excrement could be easily discharged by pulling the cap off the inner wall of the discharge section, but the excrement could not be properly discharged into the disposal area, soiling the area around the excrement area. With the device of Comparative Example 2, the rotating grip of the device was difficult to see, and the direction of rotation was also difficult to understand, making discharge difficult and not very user-friendly.

[0098] In this specification, for convenience, explanations may be made using numbers or letters such as "first, second, third...", "A, B, C...", "primary, secondary, tertiary...", etc., but this does not limit the interpretation of the present invention in a narrow sense, and the order may be changed as desired. A combination product may be a combination item or a combination, or may be a set product, a set, or a kit product or a kit. [Explanation of symbols]
