Description

[Technical Field]

[0001] The present invention relates to medical components, and more particularly to a waste collection device for temporarily collecting excrement, excretions, gases, exudates, secretions, etc. (hereinafter collectively referred to as "excrement"; the same applies hereinafter) from within a living body or on the surface of a living body. [Background technology]

[0002] In cases where a person is unable to control fecal or urinary excretion at will, or where there is 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. Those with a stoma need to have a pouch attached to the stoma that can temporarily store waste from the stoma. People who have 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] For example, Patent Document 1 discloses an ostomy appliance that includes a pouch for storing excrement and a tubular opening that is provided at the bottom of the pouch and can be closed with a cap. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special Publication No. 2017-500985 Summary of the Invention [Problem to be solved by the invention]

[0005] A medical component including a spout having a cylindrical opening and a cap for closing the opening is attached to the outlet of the pouch that contains the excrement.

[0006] When the cap is opened to discharge the excrement contained in the pouch, the cap needs to be fixed to the spout to prevent the excrement from adhering to the cap. Conventionally, a technique has been used in which a cylindrical protrusion is formed on the spout, a cylindrical recess with a smaller diameter than the protrusion is formed on the cap, and the protrusion and recess are fitted together to fix the cap to the spout.

[0007] However, the protrusions formed on the mouthpiece have problems such as an increase in the weight of the medical component and discomfort caused by the protrusions coming into contact with the skin. Furthermore, milking the mouthpiece can cause the protrusions and recesses to become disengaged. Milking refers to kneading the mouthpiece with the fingers to unclog it.

[0008] Therefore, a main object of the present invention is to improve the ease and strength of fixing when fixing a cap to a mouthpiece. [Means for solving the problem]

[0009] The present invention provides a medical component comprising a mouthpiece having a cylindrical opening, a cap having a core portion inserted into the opening, and a connecting portion connecting the mouthpiece and the cap, wherein a recess is formed on the side of the mouthpiece in which the connecting portion can be engaged. The recess may be substantially L-shaped when viewed from the front. The recess may have a groove formed in a direction substantially perpendicular to the axial direction of the opening and the direction in which the connecting portion extends, and a wall capable of supporting the connecting portion. The depth of the groove may be greater than the width of the connection portion. The connector may connect the cap to the mouthpiece at a location between the opening and the recess. The connection portion may have a bent portion that can be engaged with the recess. The recess may be formed with an insertion portion into which the connection portion can be inserted, and the insertion portion may be formed with a slope when viewed from the front. The recess may be formed with an insertion portion into which the connection portion can be inserted, and the insertion portion may be tapered when viewed from the front. The recess may be formed with an insertion portion into which the connection portion can be inserted, and the insertion portion may be formed with a protrusion. The mouthpiece, the cap, and the connecting portion may be formed from the same resin material. The mouthpiece, the cap, and the connection portion may be integrally formed. The present invention also provides a waste collection appliance comprising a pouch for collecting waste from a stoma and the medical component for discharging the waste from the pouch. [Effects of the Invention]

[0010] According to the present invention, when a cap is fixed to a mouthpiece, the ease and strength of fixation can be improved. Note that the effects described here are not necessarily limited to those described herein, and may be any of the effects described in this disclosure. [Brief explanation of the drawings]

[0012] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the embodiment described below is an example of a typical embodiment of the present invention, and the scope of the present invention is not limited thereto. Furthermore, the present invention can be combined with any of the following examples and their modifications.

[0013] In the following description of the embodiments, configurations may be described using terms including "approximately," such as "approximately parallel" and "approximately perpendicular." For example, "approximately parallel" does not only mean completely parallel, but also means substantially parallel, i.e., including a state where the orientation is deviated from the completely parallel state by, for example, a few percent. The same applies to other terms including "approximately." Furthermore, each figure is a schematic diagram and is not necessarily an exact illustration.

[0014] Unless otherwise specified, in the drawings, "upper" means the upper direction or upper side in the drawing, "lower" means the lower direction or lower side in the drawing, "left" means the left direction or left side in the drawing, and "right" means the right direction or right side in the drawing. Furthermore, in the drawings, the same or equivalent elements or members are given the same reference numerals, and redundant explanations will be omitted.

[0015] <1. First embodiment (example 1 of medical component)> The present invention provides a medical component that is attached to a pouch that contains waste from a stoma. The medical component is a medical component used, for example, in an ostomy appliance pouch, a drainage pouch, a fecal bag, a urine collection bag, or a urine collection bag.

[0016] The medical component comprises a mouthpiece having a cylindrical opening, a cap having a core that is inserted into the opening, and a connecting part that connects the mouthpiece and the cap, and a recess is formed on the side of the mouthpiece that can engage the connecting part.

[0017] The configuration of a medical component according to one embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a front view of a medical component 1 according to one embodiment of the present invention.

[0018] As shown in FIG. 1, a medical component 1 according to one embodiment of the present invention comprises a mouthpiece 11 having a cylindrical opening 111, a cap 12 having a core 121 inserted into the opening 111, and a connecting portion 13 connecting the mouthpiece 11 and the cap 12.

[0019] A recess 14 is formed on the side of the mouthpiece 11, into which the connecting portion 13 can be engaged. When the cap 12 is fixed to the mouthpiece 11, the connecting portion 13 is inserted into this recess 14. The recess 14 engages the connecting portion 13, thereby fixing the cap 12 to the mouthpiece 11. The user simply inserts the connecting portion 13 into the recess 14, improving the ease of fixing. The ease of fixing refers to the degree of ease with which the user can fix the connecting portion 13 to the recess 14. Furthermore, the connecting portion 13 inserted into the recess 14 is difficult to remove, improving the fixing strength. The fixing strength refers to the degree to which the connecting portion 13 is difficult to remove when fixed to the recess 14.

[0020] This effect also occurs in other embodiments described later, so repeated description may be omitted.

[0021] The connecting part 13 connects the cap 12 to the spout 11 at a position between the opening 111 and the recess 14. In other words, the base of the connecting part 13 is positioned above the opening 111. This makes it difficult for the cap 12 to hang down below the opening 111 when the cap 12 is fixed to the spout 11 and excrement is discharged. As a result, it is possible to reduce the adhesion of excrement to the cap 12.

[0022] The shape of the recess 14 is not particularly limited, but may be, for example, a substantially L-shape when viewed from the front. The shape of the recess 14 will be described with reference to Fig. 2. Fig. 2 is a perspective view of a medical component 1 according to one embodiment of the present invention.

[0023] 2, the axial direction of the opening 111 is the Z direction. The direction in which the connecting portion 13 extends, which is substantially perpendicular to the Z direction, is the X direction. The direction perpendicular to the X and Z directions is the Y direction.

[0024] 2, the recess 14 has a groove 141 formed in a direction (Y direction) substantially perpendicular to the axial direction (Z direction) of the opening and the direction in which the connecting portion 13 extends (X direction), and a wall 142 capable of supporting the connecting portion 13. The connecting portion 13 is inserted along the groove 141.

[0025] The fixing force is improved by forming the groove 141 in a direction (Y direction) substantially perpendicular to the axial direction (Z direction) of the opening 111 and the direction in which the connecting portion 13 extends (X direction). For example, even if the cap 12 is pulled in the X direction, the connecting portion 13 inserted into the recess 14 is unlikely to come off.

[0026] The connecting portion 13 has a bent portion 131 that can be locked into the recess 14. The portion of the connecting portion 13 between the bent portion 131 and the cap 12 is locked into the recess 14. The connecting portion 13 has the bent portion 131, which improves the fixing force. For example, even if the cap 12 is pulled in the Y direction, the connecting portion 13 is unlikely to fall off the end of the groove 141.

[0027] It is preferable that the depth r1 of the groove 141 in the approximate Z-axis direction is greater than the width r2 of the connecting portion 13 in the approximate Y-axis direction. This prevents the connecting portion 13 from protruding from the groove 141 when the connecting portion 13 is inserted along the groove 141. This improves the fixing force.

[0028] The manner in which the recess 14 locks the connecting portion 13 will be described with reference to Fig. 3. Fig. 3 is a front view of the medical component 1 according to one embodiment of the present invention.

[0029] As shown in Figure 3, the recess 14 engages the connecting portion 13. Unlike conventional techniques, which do not require the formation of a protrusion, this solves problems such as an increase in the weight of the medical component and discomfort caused by the protrusion coming into contact with the skin. Furthermore, even when the mouthpiece 11 is milked, the engagement between the protrusion and the recess is unlikely to come loose. According to the present invention, when fixing the cap 12 to the mouthpiece 11, the ease and strength of fixing can be improved.

[0030] The mouthpiece 11, cap 12, and connecting portion 13 may be formed from the same resin material. The mouthpiece 11, cap 12, and connecting portion 13 may be integrally formed. This allows the medical component 1 to be manufactured at low cost. Examples of resin materials that can be used include ultraviolet curable resin and thermoplastic elastomer resin.

[0031] The above description of the medical component according to the first embodiment of the present invention can be applied to other embodiments of the present invention unless there is a particular technical contradiction.

[0032] 2. Second embodiment (example 2 of medical component) Another embodiment of the recess 14 will be described with reference to Fig. 4. Fig. 4 is a simplified front view of the recess 14 according to one embodiment of the present invention.

[0033] 4A to 4F, recess 14 is formed with insertion portion 143 into which connecting portion 13 can be inserted.

[0034] In FIG. 4A, the recess 14 has a substantially L-shape when viewed from the front, similarly to the first embodiment.

[0035] In FIG. 4B, the insertion portion 143 has a slope when viewed from the front. The insertion portion 143 has a first surface 1431 and a second surface 1432. The connection portion 13 is inserted between the first surface 1431 and the second surface 1432. At this time, the slope is formed on the first surface 1431 so that the distance between the first surface 1431 and the second surface 1432 increases from the groove 141 side toward the opposite side of the groove 141. This increases the insertable portion, improving ease of fixation.

[0036] Although not shown in the figures, in another embodiment, for example, the first surface 1431 may be formed horizontally, and the second surface 1432 may be sloped so that the distance between the first surface 1431 and the second surface 1432 increases as one moves from the groove 141 side to the opposite side of the groove 141.

[0037] 4C, the insertion portion 143 is tapered when viewed from the front. The first surface 1431 and the second surface 1432 are sloped so that the distance between the first surface 1431 and the second surface 1432 increases from the groove 141 side toward the opposite side of the groove 141. This increases the insertable area, improving ease of fixation.

[0038] Although not shown, in another embodiment, for example, the first surface 1431 may be sloped in the opposite direction to that shown in Fig. 4C, or the second surface 1432 may be sloped in the opposite direction to that shown in Fig. 4C. Furthermore, the first surface 1431 and / or the second surface 1432 may be sloped so that the distance between the first surface 1431 and the second surface 1432 becomes shorter as one moves from the groove 141 side to the opposite side of the groove 141. This makes it difficult for the inserted connecting portion 13 to come off, thereby improving the fixing force.

[0039] 4D to 4F, a protrusion 1433 is formed on the insertion portion 143. This makes it difficult for the inserted connection portion 13 to come off, thereby improving the fixing force. As shown in FIG. 4D, the protrusion 1433 may be formed on the first surface 1431. As shown in FIG. 4E, the protrusion 1433 may be formed on the second surface 1432. As shown in FIG. 4F, the protrusion 1433 may be formed on each of the first surface 1431 and the second surface 1432. The height, width, number, etc. of the protrusions are not particularly limited.

[0040] The above description of the medical component according to the second embodiment of the present invention can be applied to other embodiments of the present invention unless there is a particular technical contradiction.

[0041] 3. Third embodiment (example of excrement collection device) The present invention provides a waste collection appliance that includes a pouch for collecting waste from a stoma and a medical component according to any of the other embodiments described above for discharging the waste from the pouch.

[0042] Examples of waste collection appliances include ostomy appliances, drainage pouches, fecal bags, urine collection bags, and urine collection bags.

[0043] An excrement collection device according to one embodiment of the present invention will be described with reference to Fig. 5. Fig. 5 is a front view of an excrement collection device 3 according to one embodiment of the present invention.

[0044] The waste collection appliance 3 shown in Fig. 5 is an ostomy appliance according to one embodiment of the present invention. As shown in Fig. 5, the waste collection appliance 3 according to one embodiment of the present invention includes a pouch 2 that collects waste from a stoma, and a medical component 1 that discharges the waste from the pouch.

[0045] The pouch 2 is formed into a sealed bag using plastic film. A base plate 22 is provided on the top of the excrement collection appliance 3. The pouch 2 is attached to the patient's stoma (stoma) using the adhesive layer of the base plate 22. Excrement is discharged into the pouch 2 through an opening 23 in the base plate 22.

[0046] The pouch 2 has an outlet 21 through which excrement is discharged. The medical component 1 is attached to the outlet 21 by heat welding or the like.

[0047] The excrement contained in the pouch 2 passes through the outlet 21 and is discharged from the opening 111 of the spout 11 provided in the medical component 1.

[0048] The above description of the excrement collection device according to the third embodiment of the present invention can be applied to the other embodiments of the present invention unless there is a particular technical contradiction. [Example]

[0049] The effects of the present invention will be specifically described below with reference to examples, but the scope of the present invention is not limited to these examples.
