Description

Technical Field

[0001] The present invention relates to a mouthpiece component for discharging the contents stored in a storage bag, a medical component, and a storage bag provided with such a component. Further, it relates to a mouthpiece component for discharging excrement, excretory fluid, gas, exudate, secretion, etc. (hereinafter, these are collectively referred to as "excrement") from inside or on the surface of a living body, a medical component, a storage bag provided with such a component, an excrement storage bag, and the like.

Background Art

[0002] When a person cannot control the excretion of feces and urine by their own will or has a disease of the digestive or urinary organs, a surgical operation may be performed to lead the intestinal or urinary tract to the body surface and create a stoma on the body surface. A person with a stoma needs to wear a storage bag such as a pouch that can temporarily store excrement from the stoma. Also, in the case of a person with a urinary stoma, a leg bag may be used to increase the urine storage volume. In addition, people with openings or wounds on the body surface due to other diseases also need to wear a storage bag around the opening or wound in order to process the excrement discharged by drainage or the like.

[0003] And the storage bags such as pouches and leg bags are equipped with a mouthpiece component which is a medical component, and the excrement accumulated in the excrement storage bag is discharged to the outside using this mouthpiece component. As this mouthpiece component, a cap-type valve that closes or opens the discharge of excrement by inserting and removing an insertion cap into a tubular discharge port, and a rotary valve that closes or opens the discharge of excrement with a rotary cock valve provided at the discharge port are mainly used.

[0004] As a cap-type mouthpiece component, for example, in FIGS. 2 and 3 of Patent Document 1, a closure 140 can be detachably coupled to an outlet body 120 by frictional engagement with the outlet body 120 at an outlet opening 122, and the frictional engagement between the plug 140 and the inner surface 131 is a sealing engagement that substantially suppresses or restricts an unintended outflow of the contents passing through the outlet opening 122, and a mouthpiece component is disclosed.

[0005] As an example of a rotary mouthpiece component, Figure 1 of Patent Document 2 discloses a mouthpiece component comprising a valve body capable of sealing to the associated container and a stem attached to the valve body having a portion that communicates with a fluid storage area, wherein the valve is moved between an open position and a closed position by rotating the stem in the gripping area.

[0015] 1. Background and Summary of the Present Invention

[0016] When discharging contents from a storage bag equipped with a spout, it is desirable for the user to remove the cap from the sealing part at the tip of the spout and discharge the contents to the intended disposal or collection point while minimizing scattering of the contents from the opened sealing part. At this time, it may be necessary to adjust the flow of the contents by holding the spout from the outside (e.g., allowing or blocking the flow, suppressing the flow, controlling the flow rate, etc.). For example, if the user can effectively suppress the flow of the contents, or switch between allowing and blocking the flow of the contents effectively, scattering of the contents during discharge can be reduced. However, skillfully adjusting the flow of the contents often depends on the individual skill and physical ability of the user.

[0017] Therefore, the main objective of the present invention is to provide a spout component that facilitates the discharge operation of contents from a storage bag, particularly the suppression of the discharge flow, and a storage bag equipped with said spout component. The contents may also be a fluid liquid.

[0018] In particular, when the contents are excrement, it is desirable from a hygienic standpoint to prevent the excrement from scattering as much as possible from the tip of the mouthpiece component. That is, the main objective of the present invention may be to provide a mouthpiece component that facilitates the discharge operation of excrement from an excrement container, in particular, the suppression of the discharge flow, and an excrement container equipped with said mouthpiece component.

[0019] As explained in the [Comparative Example] below, when conventional nozzle parts were bent, after pressing a certain part of the nozzle part with a finger, the tip of the sealing part was further bent so that it faced the mounting part, the cap part that was tightly attached to the sealing part was removed, and the tip of the opened sealing part was pointed to the desired location, and the contents were discharged in that direction. Normally, even if a certain part of the nozzle part is compressed by finger pressure to crush the hollow passage, gaps are created at both ends of the hollow passage, so when the cap part is removed and the tip of the sealing part is raised upward, the contents leak out from these gaps. Furthermore, when the tip of the opened sealing part is lowered from the top to the bottom, the contents leak out from these gaps at both ends. For this reason, when using conventional nozzle parts, leakage suppression relies heavily on individual skill such as speed and dexterity of action, and therefore, it was not easy for the user to suppress the flow of contents, especially to block the flow.

[0020] In response to this, the inventors have provided a flexible portion (preferably a flexible cylindrical portion) of the mouthpiece component with a bendable portion on at least a part of its outer circumference, where the wall thickness is thinned along the circumferential direction to make it easier to bend. This bendable portion can serve as the starting point for deformation when an external force is applied. In this way, the inventors have found that by using this bendable portion to suppress leakage, the operation of discharging the contents from the storage bag, particularly suppressing leakage, can be easily performed, and have completed the present invention. Furthermore, it was discovered that by providing steps or grooves on the outer wall of the flexible cylindrical part as a bend for spillage suppression, and applying force to this part, the discharge of contents can be suppressed more easily. Furthermore, we found that a hollow, approximately elliptical cross-sectional shape, preferably a hollow, approximately elongated elliptical shape, in the direction perpendicular to the flow path of the flexible cylindrical portion is preferable, as it facilitates the suppression of the discharge of contents. Furthermore, it was found that even if the bent portion for suppressing leakage is provided at a specific position in the flow direction from the sealing portion to the mounting portion (preferably a specific position in the flow direction of the flexible cylindrical portion), when the total length of the fitting component in the flow direction is considered to be 100%, the leakage of contents can be easily suppressed.

[0021] Based on the above, this technology is a mouthpiece component that is attached to the bag portion that contains the contents. A flexible cylindrical part having a hollow channel through which the contents flow, An attachment portion is provided at one end of the flexible cylindrical portion and is connectable to the bag portion, A sealing portion is provided at the other end of the flexible cylindrical portion to seal the hollow flow path, Equipped with, The flexible cylindrical portion can provide a mouthpiece component having a flow-suppressing bend provided along the circumferential direction on at least a portion of its outer circumference. Furthermore, this technology can provide a storage bag having the aforementioned mouthpiece component.

[0022] Furthermore, in a preferred embodiment, the flow-suppression bent portion preferably has a step or groove that serves as the starting point for deformation when an external force is applied. Furthermore, in a preferred embodiment, the flow-suppression bend is preferably located at a position of 95% or less from the end of the sealing portion, when the total length in the direction of the hollow flow path of the mouthpiece component is taken as 100%. Furthermore, in a preferred embodiment, the cross-sectional shape of the flexible cylindrical portion of the mouthpiece component, which is substantially perpendicular to the flow path direction, is preferably substantially elliptical. Furthermore, in a preferred embodiment, the contents are preferably excrement.

[0023] 2. Mouthpiece parts according to this embodiment

[0024] An example of the configuration of a medical component according to one embodiment of the present invention will be described with reference to Figures 1 to 8, but the present invention is not particularly limited to the configuration and description of one embodiment, these drawings and reference numerals.

[0025] In this embodiment, the mouthpiece component 1 is preferably attached to the bag portion 101 that contains the contents. The mouthpiece component 1 may be a medical component. The mouthpiece component 1 is preferably flexible and preferably made of a flexible resin. The bag portion 101 is not particularly limited, but may be, for example, a waste collection bag. Examples of waste collection bags are not particularly limited, but include pouches for collecting waste from a stoma and leg bags. One or more of these may be selected.

[0026] The mouthpiece component 1 preferably has a hollow channel 5 on its inside from which the contents can be discharged. The contents flowing from the bag portion 101 into the mouthpiece component 1 pass sequentially through the hollow channel of the attachment portion 20, the hollow channel of the flexible cylindrical portion 30, and the hollow channel of the sealing portion 40, and can be discharged to the outside from the discharge port at the end of the sealing portion. In this embodiment, the contents may be replaced with a fluid (preferably a liquid), and it is more preferable that the contents are low viscosity, such as those intended for discharge operations with an ileostomy appliance. The direction of the channel may be said to be the Z-axis direction or the central axis direction. In addition, the substantially horizontal direction in this embodiment may be a direction perpendicular to the direction of the channel, and may be said to be the X-axis and / or Y-axis direction.

[0027] The mouthpiece component 1 is preferably hollow and substantially cylindrical, and more preferably elongated and substantially cylindrical, with a length in the direction of the flow path being greater than the length in the direction perpendicular to the flow path. The mouthpiece component 1 is more preferably having a hollow flow path 5 inside the substantially cylindrical shape for discharging contents (e.g., stoma-derived excrement). The three-dimensional shape of the hollow flow path is not particularly limited, but examples include a hollow substantially regular cylinder, a hollow substantially elliptical cylinder, a tapered shape, or a cylindrical shape with a tapered edge (e.g., a hollow inverted substantially elliptical frustum, a hollow inverted substantially cone frustum). Note that the "approximately elliptical" in "approximately elliptical cylinder" and "inverted substantially elliptical frustum" can be appropriately replaced with the "approximately elliptical" explanation described later. Furthermore, the cross-sectional shape of the hollow flow path along the flow path direction is not particularly limited, but examples include a square shape (rectangular, trapezoidal, etc.) and a tapered shape (inverted triangular, inverted trapezoidal, etc.). One or more of these shapes can be selected.

[0028] The mouthpiece component 1 preferably comprises a flexible cylindrical portion 30 having a hollow channel 5 through which the contents flow, an attachment portion 20 provided at one end of the flexible cylindrical portion 30 and connectable to the bag portion 101, and a sealing portion 40 provided at the other end of the flexible cylindrical portion 30 and sealing the hollow channel 5. It is preferable that the mouthpiece component 1 is composed of the attachment portion 20, the flexible cylindrical portion 30, and the sealing portion 40, and it is more preferable that they are arranged in the order of attachment portion 20, flexible cylindrical portion 30, and sealing portion 40 from top to bottom. It is preferable that the mouthpiece component 1 is an integrally molded product in which these parts are molded from the same resin material. Furthermore, the mouthpiece component 1 may also be provided with a cap portion 50 that is inserted into the sealing portion 40, and may be an integrally molded product of a cap portion and a cap portion which is integrally molded with the cap portion 50 described later, and it is preferable that these parts are made of the same resin material.

[0029] The area of ​​the mounting portion 20 or the height in the flow direction (distance in the Z-axis direction) is preferably the area or height from one end of the portion connectable to the bag portion 101 (for example, the upper end of the mouthpiece component 1) to one end of the flexible cylindrical portion 30. The area of ​​the sealing portion 40 or the height in the flow direction (distance in the Z-axis direction) is preferably the area or height in the flow direction in which the outer wall of the cap portion 50, when inserted from the discharge port direction of the mouthpiece component 1 and sealed, is in contact with the inner wall on the hollow flow path side. The region of the flexible cylindrical portion 30 or its height in the flow direction (distance in the Z-axis direction) is preferably the region or height from the lower end of the mounting portion to the upper end of the sealing portion 40. For example, in the case of the mouthpiece part 1 shown in Figure 3A, the cap portion 50 is inserted up to the dashed line portion in the direction of the outlet and seals the hollow flow path, so the portion from the dashed line portion in the direction of the outlet to the outlet may be the sealing portion 40. Also, since the sealing portion of the bag portion is connected at the dashed line portion in the direction of the bag portion, the portion from the upper end of the mouthpiece part to the dashed line portion in the direction of the bag portion may be the mounting portion 20. Furthermore, the portion from the upper end to the lower end of the dashed line may be the flexible cylindrical portion 30.

[0030] The flexible cylindrical portion 30 preferably has a flow-suppressing bend portion 10 provided along the circumferential direction on at least a part of its outer circumference. The flow-suppressing bend portion 10 is preferably provided in a direction substantially perpendicular to the flow path direction.

[0031] The spillage-suppressing bend 10 is preferably formed around the entire circumference or a portion of the outer circumference of the flexible cylindrical portion 30. When the spillage-suppressing bend is around the entire circumference, as shown in Figure 3, the spillage-suppressing bend is provided on both the front and back surfaces. When the spillage-suppressing bend is only around a portion of the circumference, for example, as shown in Figure 2, it may be provided up to 1 / 2 of the entire circumference, or it may be 1 / 4 or more, 2 / 3 or more, or 1 / 2 or more of the circumference, and an appropriate upper limit may be set, for example, 3 / 4 or less, or 1 / 2 or less of the entire circumference. Furthermore, it is preferable that the spill-suppressing bend portion 10 be provided on the outer circumference of the mouthpiece component on the distal side. The distal side is the side farther from the user's body, and the proximal side is the side closer to the user's body. By providing the spill-suppressing bend portion 10 at the distal position, it is easier for the user to confirm the spill-suppressing bend portion 10 with their fingers, resulting in good operability such as easy bending and folding, and making it easier to suppress the spillage of contents. Furthermore, it is preferable that the spill-suppressing bend portion 10 be provided in the shape of a horizontal line when the outside of the flexible cylindrical portion is viewed from the front or back, and it is preferable that it be a horizontal line substantially perpendicular to the flow direction. Furthermore, it is preferable that the spill-suppressing bend portion 10 be provided so as to intersect with the central axis in a plan view when viewed from the front or back, and it is more preferable that it be provided in a direction substantially perpendicular to the central axis. When the mouthpiece component 1 is attached to the bag portion 101, it is preferable that the horizontal line spill-suppressing bend portion 10 be formed at least on the outer surface side (for example, the front side) which is at the distal position to the user.

[0032] The spill-suppressing bend portion 10 is preferably configured to be the starting point for deformation when an external force, such as a finger, is applied to the flexible part of the mouthpiece component. More preferably, the spill-suppressing bend portion 10 is configured such that the mouthpiece component (preferably the flexible cylindrical part) and the hollow flow channel inside it bend from the bend portion, and the inner wall of the mouthpiece component can come into contact or be tightly sealed as a result of the bending. This allows for better suppression or prevention of the spillage of contents.

[0033] The structure or shape of the outflow-suppressing bent portion 10 is not particularly limited, but it is preferable to provide a structure or shape that allows bending, such as grooves or steps, on the outer wall of the mouthpiece component 1, and more preferably on the outer wall of the flexible cylindrical portion 30. It is more preferable that the bent portion is configured such that when bent, the outer wall of the flexible cylindrical portion becomes L-shaped or V-shaped (for example, acute angle when viewed from the side).

[0034] The flow-suppression bend 10 is preferably a horizontal line when viewed from the front or back, and may be a line (preferably a straight line) in a direction substantially perpendicular to the flow direction. The flow-suppression bend 10 is preferably provided along the circumferential direction on at least a part of the outer circumference of the mouthpiece component (preferably a flexible cylindrical part). At least a portion of the outer perimeter may be the entire circumference of the outer wall, or it may be half or a portion of the circumference of the front or back outer wall. The spill-suppressing bend 10 may be provided around the entire circumference of the outer wall, or as a partial circumference on approximately the same circumference on the front and back outer walls, or as a half-circumference or partial circumference on the front or back outer wall. The spill-suppressing bend 10 can become the starting point for bending of the hollow flow path 5 by applying force around it with a finger or the like. It is preferable to provide the spill-suppressing bend 10 on the surface distal to the user (for example, the front) so that the discharge port is at the distal position when bent. It is preferable that the thickness of the portion with the bend is thinner than the thickness of the portion without the bend, making it easier to bend. The front of the mouthpiece component 1 may be the surface proximal to the user using the mouthpiece component 1, and the back of the mouthpiece component 1 may be the surface distal to the user.

[0035] The outer circumference of the spillage-suppressing bend 10 may be continuous or intermittent. The length of the outer circumference of the spillage-suppressing bend 10 is not particularly limited, but when the outer circumference in the lateral direction (X-axis direction) of the flexible cylindrical part is taken as 1, the lateral outer circumference of the spillage-suppressing bend 10 is preferably 0.1 or 0.2 or more, more preferably 0.25 or 0.3 or more, and even more preferably 0.4 or 0.5 or more as a suitable lower limit, and preferably 1 or 0.5 or less as a suitable upper limit, for example, the numerical range may be 0.3 to 1 or 0.5 or more and 1.0 or less.

[0036] The position of the outflow-suppressing bend 10 in the flow direction is not particularly limited, but the relative position when the total length of the mouthpiece component 1 in the flow direction is 100% is not particularly limited, but a suitable upper limit with respect to 100% of the total length of the mouthpiece is preferably 95% or less, more preferably 90% or less, and even more preferably 85% or less from the bottom end of the total length, considering the jointability with the bag seal portion and the user's operability. A suitable lower limit is preferably 30% or more, more preferably 50% or more, from the bottom end of the total length, in terms of preventing the contents from adhering to the user, etc. The bottom end of the total length may be the same as the bottom end of the sealing portion (end of the outlet). As shown in Figures 2 and 3, the total length of the mouthpiece (in the Z-axis direction) is L1, and the distance in the Z-axis direction from the lower end of the total length to the flow-suppressing bent portion 10 is L2.

[0037] The position of the outflow suppression bend 10 in the flow path direction (Z-axis direction) is not particularly limited, but is preferably 5 mm or more, more preferably 10 mm or more, and even more preferably 15 mm or more from the upper end of the overall length.

[0038] Figure 4 is a substantially vertical cross-sectional view of a wall having a discharge-suppressing bend on the outer circumference of a flexible cylindrical section. The cross-sectional shapes of the discharge-suppressing bend shown in Figure 4 are open outwards, with Figure 4A being V-shaped, Figure 4B being an inverted V-shaped trapezoid, Figure 4C being a U-shaped with a curved bottom, Figure 4D being a stepped shape with a greater thickness in the downward direction of the step, and Figure 4E being a stepped shape with a greater thickness in the upward direction of the step. In the figures, D indicates the depth or step of the cross-sectional shape, W indicates the width of the cross-sectional shape, and α indicates the angle of the slope. The cross-sectional shape of the flow path direction of the flow-restraining bend 10 can be a V-shape, trapezoidal (inverted V-shape), U-shape, L-shape, or other groove, as well as a step-like difference in height where the thickness of the inner wall increases or decreases in the direction of the sealing portion (see Figures 4A to 4E). The groove is preferably provided to open in the distal position direction or outward direction. Of these, a trapezoidal (inverted V-shape) groove, an L-shaped groove, and a step where the thickness of the inner wall decreases in the direction of the discharge port are preferred from the viewpoint of bending. One or more of these can be selected.

[0039] The "groove depth (D)" in the cross-sectional shape of the flow path direction of the outflow-suppressing bend 10 is not particularly limited, but a preferred upper limit is preferably 20 mm or less, more preferably 10 mm or less, and even more preferably 5 mm or less, and a preferred lower limit is preferably 0.01 mm or more, more preferably 0.05 mm or more, and even more preferably 0.1 mm or more. The "groove depth (D)" may also be the distance from the outer wall to the bottom of the groove in the substantially horizontal direction or the Y-axis direction.

[0040] The "groove width (W)" in the cross-sectional shape of the flow path direction of the outflow-suppressing bend 10 is not particularly limited, but a suitable upper limit is preferably 20 mm or less, more preferably 10 mm or less, and even more preferably 5 mm or less, and a suitable lower limit is preferably 0.01 mm or more, more preferably 0.05 mm or more, and even more preferably 0.1 mm or more. The "groove width (W)" may also be the distance in the Z-axis direction or vertical direction between the outer walls with respect to this groove.

[0041] The difference in step height in the cross-sectional shape of the flow path direction of the outflow-suppressing bent section 10 is not particularly limited, but a preferred upper limit is preferably 20 mm or less, more preferably 15 mm or less, and even more preferably 10 mm or less, and a preferred lower limit is preferably 0.01 mm or more, more preferably 0.05 mm or more, and even more preferably 0.1 mm or more. It is preferable that the "difference in step height" is the difference in height of the part where the step height occurs (the difference in thickness in the approximately horizontal direction or the Y-axis direction). Furthermore, the angle (α°) of the stepped slope in the cross-sectional shape of the flow path direction of the outflow-suppressing bend 10 is not particularly limited, but a preferred upper limit is preferably 170 degrees or less, more preferably 160 degrees or less, and even more preferably 150 degrees or less, and a preferred lower limit is preferably 1 degree or more, more preferably 2.5 degrees or more, and even more preferably 5 degrees or more.

[0044] The wall thickness of the mouthpiece part 1 is not particularly limited, but is preferably 0.1 to 25 mm, more preferably 0.2 to 23 mm, and even more preferably 0.5 to 20 mm. The wall thicknesses of the mounting part 20, the flexible cylindrical part 30, and the sealing part 40 may also be appropriately combined by adopting the upper and lower limits of the numerical range for the wall thickness of the mouthpiece part 1. For example, the wall thickness of the flexible cylindrical part of the mouthpiece part 1 is not particularly limited, but is preferably 0.1 to 25 mm, more preferably 0.2 to 23 mm, and even more preferably 0.5 to 20 mm.

A bag used to accumulate a large amount of excrement preferably comprises a connecting part that connects to the outlet or stoma opening of an ostomy device with a tube or the like, a bag for accumulating excrement, and a mouthpiece used in this embodiment for discharging the accumulated excrement to the outside.

[0052] The mouthpiece component described above is preferably attached to the bag portion 101 (preferably a waste collection bag), and the waste collection bag can be a pouch, a bag, etc., but is not limited to these. Of these, the mouthpiece component is preferably attached to the pouch or bag in which the waste is collected, but the use of the pouch is not particularly limited, and examples include stomas (e.g., colostomy, ileostomy, urostomy, etc.), drains, etc., and one or more of these can be selected. Furthermore, the mouthpiece component described above is more preferably a mouthpiece for an excrement container used for low-viscosity excrement, and the low-viscosity excrement container is preferably one or more types selected from, for example, those for ileostomy and those for urostomy.

[0053] As shown in Figures 1 and 6, the mouthpiece component 1 may be provided with a sealing portion 40 for sealing the discharge of contents to the outside, and a cap portion 50 for inserting into the sealing portion 40 to seal the flow of contents, and the cap portion 50 can further suppress leakage of contents. For example, from the viewpoint of further suppressing the leakage of contents as described above, it is preferable that the mouthpiece component 1 further includes a cap portion 50 that can be inserted into and in contact with the opening (discharge port) for discharge of the sealing portion of the mouthpiece component 1, and the cap portion may have one or more pleats. In this embodiment, it is preferable that the mouthpiece component 1 is integrally molded with the cap portion 50. Alternatively, it may be an integrally molded product of the mouthpiece component 10, the cap portion 50 and a connecting portion for connecting to the cap portion, and the connecting portion may be connected to any part provided on the mouthpiece component 1, for example, it may be connected to the outside between the flexible cylindrical portion 30 and the sealing portion 40. The medical component may include a one-piece molded product in which the mouthpiece component 1 and the cap portion 50 are integrally molded. Preferably, the mouthpiece component 1 and the cap portion 50 are molded from the same resin material, and more preferably, the resin material is a flexible resin material.

[0054] As a preferred embodiment example 1 of this embodiment, a mouthpiece component 1 is shown in Figures 1, 2, 5, and 6. The mouthpiece component 1 has a horizontally elongated, substantially elliptical cone-shaped funnel form. As shown in Figure 6, the outflow-suppressing bend 10 is provided on the horizontally elongated, substantially elliptical cone-shaped flexible cylindrical portion 30 and is positioned above the upper end of the sealing portion to which the cap portion 50 is sealed. Note that the flexible cylindrical portion 30 in embodiment example 1 may be a horizontally elongated hollow semi-ellipsoid or hollow hemisphere, and the upper end of the sealing portion may be at approximately the same position as the outflow-suppressing bend 10. In embodiment example 1, the outflow-suppressing bend 10 is provided on the front of the mouthpiece component 1 and is arranged as a horizontal groove (V-shape) on a straight line over approximately half a circumference, and is located at positions of 95% or less and 50% or more from the end of the sealing portion (discharge port) when the total length in the flow direction of the mouthpiece component 1 is taken as 100%. The hollow channel 5 can be easily bent and returned to its original shape by pressing around the outflow-suppressing bend 10 with a finger or the like, thereby easily suppressing the flow of contents. The sealing portion 40 in Embodiment Example 1 may be hollow and substantially cylindrical (for example, substantially a perfect cylinder, substantially an elliptical cylinder).

[0055] As a preferred embodiment example 2 of this embodiment, a mouthpiece component 1 as shown in Figure 3 can be cited. The mouthpiece component 1 has a horizontally elongated, substantially elliptical cone-shaped funnel shape. In embodiment example 2, the upper end of the sealing portion of embodiment example 2 is positioned closer to the outlet than the upper end of the sealing portion of embodiment example 1, and the height of the sealing portion in the Z-axis direction of embodiment example 1 and embodiment example 2 may be the same. In embodiment example 2, the total length of embodiment example 2 may be longer than the total length of embodiment example 1. As shown in Figure 3, the outflow-suppressing bend portion 10 of embodiment example 2 is provided on the horizontally elongated, substantially elliptical cone-shaped flexible cylindrical portion 30 and is positioned above the upper end of the sealing portion to which the cap portion 50 is sealed. In embodiment example 2, the outflow-suppressing bend portion 10 is provided around the entire horizontal circumference of the mouthpiece component 1 and is arranged as a straight horizontal groove (V-shape). The flow-suppression bend portion 10 is located at positions 95% or less and 30% or more from the end of the sealing portion (discharge port) when the total length of the mouthpiece component 1 in the flow direction is taken as 100%. By pressing around the flow-suppression bend portion 10 with a finger or the like, the hollow flow path 5 can be easily bent and returned to its original shape, and the flow of contents can be easily suppressed. Note that the sealing portion 40 in embodiment example 2 may be hollow and substantially cylindrical (for example, substantially a perfect cylinder, substantially an elliptical cylinder).

[0056] The mouthpiece component 1 described above can be molded using a resin material as the raw material and known molding methods such as injection molding. Examples of resin materials that can be used include ultraviolet curing resin, thermoplastic elastomer resin, urethane resin, silicone resin, synthetic rubber, natural rubber, and thermoplastic resin. In this embodiment, flexible resin is preferred from the viewpoint of adjusting the force applied by fingers, etc.

[0057] 3. A storage bag (preferably a waste storage device) according to this embodiment.

[0058] This embodiment provides a bag portion having the mouthpiece component 1 described above. The bag portion is preferably for containing contents, and may be a storage bag or storage device. The contents contained in the bag portion may be excrement. In a preferred embodiment, an excrement storage device can be provided comprising a mouthpiece component 1 and an excrement storage bag (preferably a pouch for excrement from a stoma) for containing excrement, wherein the excrement storage bag has a sealing portion 40 for discharging or sealing the excrement with a cap portion 50, and a mounting portion for a medical component is attached to the outlet.

[0059] Examples of waste collection devices include ostomy appliances, drainage pouches, defecation bags, urine collection bags, and leg bags, from which one or more types can be selected.

[0060] An excrement collection device according to one embodiment of the present invention will be described with reference to Figure 8. Figure 8 is a front view showing an example of the configuration of a collection bag 100 according to one embodiment of the present invention. The collection bag may also be an excrement collection device.

[0061] The storage bag 100 shown in Figure 8 is more preferably an ostomy appliance. The storage section 101 is formed in the shape of a sealed bag using a plastic film. The storage bag 100 may have an opening into which the contents flow in, and this opening may be located anywhere on the storage bag, but it is preferable to have it located at the top. For example, in the case of the storage bag 100, a faceplate 102 is provided at the top of the storage bag 100. The adhesive layer of this faceplate 102 attaches the pouch 101 to the patient's stoma. The patient's excrement is discharged into the pouch 101 through the holes 103 in the faceplate 102 and is accumulated. The storage section may also be a bag.

[0062] As shown in Figures 8, 7, and 1, a storage bag 100 according to one embodiment comprises a mouthpiece component 1 and a storage section (e.g., a pouch) 101 that contains waste from the stoma. The storage section 101 has an outlet from which the contents (preferably waste) are discharged, and this outlet is connected to the attachment portion 20 of the mouthpiece component 1. The sealing portion 40 of the mouthpiece component 1 has a cap 50 inserted into it to seal off the discharge of waste. By maintaining this sealed state, waste is prevented from being discharged from the storage bag 100 containing the waste.

[0063] As shown in Figure 7, the user can apply force with their fingers or the like around the spill-suppressing bend portion 10, which is provided on the mouthpiece component 1 of the storage bag 100 and acts as the starting point for deformation when an external force is applied, to bend the flexible cylindrical portion 30 into a V shape, starting from the bend portion 10, so that the tip of the discharge opening of the sealing portion 40 is raised upward. Specifically, by pinching the spill-suppressing bend portion 10 with the sides of the thumb and middle finger and pressing the hollow channel 5 from opposing directions, the flexible cylindrical portion 30 can be bent into a V shape, starting from the spill-suppressing bend portion 10. As a result, the inner wall of the flexible cylindrical portion of the mouthpiece component comes into contact and bends, blocking or suppressing the flow of contents in the hollow channel. After bending into a V shape, the cap portion 50 inserted into the sealing portion 40 for sealing is removed. Then, with the cap portion 50 removed, the V-shaped bend is released with a finger or the like, returning it to its original state, and the tip of the discharge port of the opened sealing portion is directed towards the discharge location, allowing the contents to be discharged from the storage bag 100 through the hollow channel 5. This makes it easy to discharge the contents from the storage bag. Also, because it can be easily bent, discharge can be easily suppressed. Furthermore, the state of suppressing the discharge of contents can be easily set and maintained, and the open state can also be easily set, so the scattering of contents can be suppressed more effectively.

[0064] Therefore, the process of discharging the contents from the containment bag, especially controlling the discharge, can be easily performed. Furthermore, when living with the containment bag attached, the disposal of waste can be easily carried out. [Examples]

[0065] The effects of the present invention will be specifically described below with reference to examples. However, the scope of the present invention is not limited to the examples described herein.

[0066] <Manufacturing Example 1> The medical components (mouthpieces in Example 1 and Comparative Example 1) were manufactured by injection molding using a flexible thermoplastic resin.

[0067] Mouthpiece part of Example 1 The mouthpiece component of Example 1 has the external shape shown in Figures 1, 2, 5, and 6, and the flow-suppressing bent portion 10 has a half-circumferential lateral groove in the flexible cylindrical portion 30 as shown in Figure 2. The mouthpiece component 1 of Example 1 is integrally molded from flexible resin, with the mounting portion 20, the flexible cylindrical portion 30, and the cap portion 50 connected via a connecting portion to form a sealing portion 40.

[0068] As shown in Figure 8, the attachment was made to the bag portion 101 to obtain a storage bag 100 having the mouthpiece component 1. In Embodiment 1, the external shape of the attachment portion 20 and the flexible cylindrical portion 30 is a funnel-shaped tapered shape (a combination of a short hollow cylindrical shape below a hollow semi-ellipsoid) when viewed from the front, and the external shape of the sealing portion is approximately rectangular when viewed from the front. The attachment portion 20 and the flexible cylindrical portion 30 are tapered so that the major and minor axes of the hollow flow path of the attachment portion 20 are slightly larger than the major and minor axes of the hollow flow path of the flexible cylindrical portion 30, allowing the contents to flow easily towards the outlet. The sealing portion 40 is the area up to the part where the outer wall of the cap portion 50 contacts the inner wall of the mouthpiece component 1, and since the tip of the cap portion 50 is approximately frustoconical in shape, the tip does not contact the inner wall. The height of the contact point between the outer wall of the cap portion 50 and the inner wall of the hollow flow path 5 (the upper end of the sealing portion 40) is below the flow rate suppression inflection portion 10. Furthermore, the cross-sectional shape of the nozzle component 1 in a direction approximately perpendicular to its approximately central axis is a horizontally elongated, approximately elliptical shape.

[0069] The total length of the mouthpiece component 1 in the flow path direction was 45 mm. The long diameter of the hollow flow path 5 in the mounting portion 20 was 33 mm and the short diameter was 10 mm, with a wall thickness of 7 mm on the long diameter side and 2 mm on the short diameter side. The major axis of the hollow channel 5 in the flexible cylindrical portion 30 and the sealing portion 40 was 25 mm, the minor axis was 10 mm, and the wall thickness was 3 mm. The half-circumferential transverse groove (horizontal straight line) 10a was a V-shaped groove as shown in Figure 4A, covering half of the circumference (50%), with a groove depth (D) of 1 mm and a groove width (W) (between top and bottom) of 1 mm.

[0070] For example, it is possible to manufacture a mouth part 1b having a step 4d on half of the flexible cylindrical part 30, as shown in Figure 4D, instead of the half-circumferential horizontal groove (horizontal straight line) 10a of the mouth part 1 product of Example 1. The height difference of this step 4d is 1 mm, and the angle of the step slope is 70 degrees.

[0071] <Oral fitting component of Comparative Example 1> The mouthpiece component of Comparative Example 1 was manufactured in the same manner as the mouthpiece component of Example 1, except that it did not have a half-circumferential horizontal groove (horizontal straight line) 10.

[0072] <Evaluation of ease of flow rate adjustment> (1) The dog food was degreased, water was added to adjust the moisture content to 90%, and it was mixed in a blender for 1 minute. (2) 100g of the above-mentioned (1) was placed into the pouch with the mouthpiece attached. To prevent the contents from being discharged from the hollow channel of the mouthpiece, the outside of the flexible cylindrical part of the mouthpiece was pressed with the tip of the thumb to crush the hollow channel, and the cap was removed while bending it into a V shape with the other fingers, and then the mouthpiece was turned downwards while maintaining its bend. If there was a step on the outside of the flexible cylindrical part, the stepped part was pressed with the tip of the thumb to crush the hollow channel, and the flexible cylindrical part was bent into a V shape with the other fingers. (3) Points were awarded based on the weight of the contents expelled from the mouthpiece within 30 seconds. 1 item: 30g or more. Two points: Less than 30g, 20g or more. 3 points: Less than 20g, 10g or more. 4 points: Less than 10g, 5g or more. 5 points: Less than 5g.

[0073] [Table 1]

[0074] <Result> As shown in Figure 7, in Example 1, when the mouthpiece was bent at the lateral groove 10, the inner walls of the mouthpiece adhered to each other in a linear fashion, which suppressed the discharge of the contents. On the other hand, in Comparative Example 1, because there was no lateral groove 10, the inner walls of the mouthpiece could not adhere to each other in a linear fashion when bent, making it difficult to suppress the discharge of the contents.

[0075] In this specification, numbers, letters, etc., such as "first, second, third...", "A, B, C...", and "primary, secondary, tertiary...", may be used for convenience in explanations. However, this does not mean that the present invention will be narrowly limited in meaning by order or other criteria, and the order may be changed at will. A combination product may be a combination item or a combination, or it may be a set product, a set or kit product or kit. [Explanation of Symbols]
