Description

Medical Care Products CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This international application claims the benefit of Japanese Patent Application No. 2023-194474, filed with the Japan Patent Office on November 15, 2023, and Japanese Patent Application No. 2024-001857, filed with the Japan Patent Office on January 10, 2024, the entire disclosures of which are incorporated herein by reference.

[0002] FIELD OF THE DISCLOSURE The present disclosure relates to medical care products.

[0003] Labor pains are the pain caused by uterine contractions pushing the fetus out of the uterus. As labor pains begin and the fetal head descends, it stimulates nerves near the mother's tailbone, causing the mother to feel the urge to "push." ​​Pushing helps push the fetus out of the uterus. On the other hand, pushing before the cervix is ​​fully dilated can cause swelling or injury to the birth canal. Therefore, it is necessary to suppress the urge to push during labor, known as "pushing relief," until the cervix is ​​fully dilated. One known method for pushing relief during labor is to use a tennis ball or golf ball to press against the anus, as described in Patent Document 1, for example.

[0004] Patent No. 6421353

[0005] However, some pregnant women may want to have pressure applied to other areas at the same time as the area around the anus to relieve straining, and it is difficult to apply pressure to two areas simultaneously using a tennis ball or golf ball.

[0006] One aspect of the present disclosure is to provide a medical care product that can easily press a first region that includes the anus and a second region that is different from the first region at the same time.

[0007] One aspect of the present disclosure is a medical care product comprising a first pressing portion, a second pressing portion, and a connecting portion. The first pressing portion is configured to press a first region that includes the anus. The second pressing portion is configured to press a second region that is different from the first region. The connecting portion connects the first pressing portion and the second pressing portion. Each of the first pressing portion and the second pressing portion has a bottom portion and a bulging portion that bulges upward from the bottom portion. This configuration makes it easy to simultaneously press the first region and the second region in the medical care product.

[0008] In one aspect of the present disclosure, the lower surface of the bottom portion may be flat, which can increase the stability of the medical care product on the placement surface when the medical care product is placed on the placement surface.

[0009] In one aspect of the present disclosure, the bulging portion may have a top portion including an apex of the bulging portion. The outer surface of the top portion may be curved upward. This configuration makes it easier to press the first region and the second region as a whole.

[0010] In one aspect of the present disclosure, the connecting portion may connect the bulging portion of the first pressing portion and the bulging portion of the second pressing portion. The upper surface of the connecting portion may be curved, having a first ridgeline extending from the bulging portion of the first pressing portion to the bulging portion of the second pressing portion, and a second ridgeline intersecting the first ridgeline. The first ridgeline may be curved downward. The second ridgeline may be curved upward.

[0011] In one aspect of the present disclosure, at least one of the first pressing portion and the second pressing portion may further include a recess recessed from the lower surface of the bottom portion toward the inside of the bulging portion. With this configuration, at least one of the first pressing portion and the second pressing portion can be made more flexible.

[0012] In one aspect of the present disclosure, the device may further include a hot / cold agent configured to be capable of keeping at least one of hot and cold. The hot / cold agent may be disposed in the recess. With this configuration, it is possible to heat or cool at least one of the first pressing portion and the second pressing portion.

[0013] In one aspect of the present disclosure, the hot / cold agent may be disposed with a gap between it and at least a portion of the inner surface of the recessed portion. With this configuration, it is possible to prevent at least one of the first pressing portion and the second pressing portion from being excessively heated or cooled.

[0014] According to an aspect of the present disclosure, the device may further include a closing member configured to close the opening of the recess. With this configuration, the recess and the closing member can form a space inside the bulge portion.

[0015] One aspect of the present disclosure may further include an auxiliary member. The auxiliary member may have an insertion portion and a gripping portion. The insertion portion is configured to be inserted into the recess. The gripping portion is provided in the insertion portion and configured to be gripped by an assistant. This configuration makes it easier for the assistant to support the medical care product.

[0016] In one aspect of the present disclosure, the height of the first pressing portion may be greater than the height of the second pressing portion. With this configuration, it is possible to more easily press the first region and the second region simultaneously.

[0019] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings.

[0020] 1. First Embodiment 1-1. Configuration of Medical Care Product The medical care product 1A shown in Fig. 1 is an item used to relieve straining during labor. The medical care product 1A includes a main body member 2 and a blocking member 6.

[0021] In the following description and drawings, the terms "upper" and "lower" refer to the state in which the main body member 2 is placed on a planar placement surface S with bottoms 31, 41, and 51 (described later) facing downward, as shown in Fig. 6. The same applies to the second to fourth embodiments (described later).

[0022] <Main body member> The main body member 2 is a member configured to press a specific region in the range from the coccyx to the perineum. The main body member 2 is flexible. The main body member 2 is made of, for example, resin. The main body member 2 of this embodiment is made of elastomer. The main body member 2 is manufactured by, for example, injection molding. The main body member 2 is, for example, disposable. The main body member 2 includes a first pressing portion 30, a second pressing portion 40, and a connecting portion 50.

[0023] (First Pressing Portion) The first pressing portion 30 is a portion configured to press a first region. The first region is a region that includes the anus. The first region is included in the range from the coccyx to the perineum. As shown in Figures 2 and 3 , the first pressing portion 30 has a bottom portion 31, a bulging portion 32, a recessed portion 33, and a reinforcing portion 34.

[0024] The bottom portion 31 is a portion that forms a flat lower surface 31 a. The lower surface 31 a of the bottom portion 31 corresponds to the lower surface of the first pressing portion 30.

[0025] A fitting portion 311 is provided on the outer surface 31b of the bottom portion 31. The fitting portion 311 is a portion that protrudes from the outer surface 31b of the bottom portion 31. As shown in Fig. 4, the fitting portion 311 in this embodiment has a generally triangular outer shape when viewed from above. The fitting portion 311 is configured to be able to fit into a fitted portion 621 (described later) of the blocking member 6.

[0026] The bulging portion 32 is a portion that bulges upward from the bottom portion 31. In other words, the bulging portion 32 is a portion that bulges out from the bottom portion 31 toward the side opposite the lower surface 31a. The bulging portion 32 has an apex 321 and an outer periphery 322.

[0027] The apex 321 is a portion including the apex P1 of the bulge 32. As shown in FIG. 6 , the apex P1 of the bulge 32 is the point with the highest height H1 in the bulge 32. When the medical care product 1A is used with the main body member 2 alone as described below, the height H1 of the bulge 32 refers to the height H1 of the bulge 32 from a planar placement surface S when the main body member 2 is placed on the planar placement surface S with the bottoms 31, 41, and 51 facing downward. When the medical care product 1A is used with the blocking member 6 attached to the main body member 2 as described below, the height H1 of the bulge 32 refers to the height H1 of the bulge 32 from the placement surface S when the main body member 2 with the blocking member 6 attached is placed on the planar placement surface S with the blocking member 6 facing downward as shown in FIG. 6 . The same applies to the height H2 of the bulge 42 of the second pressing portion 40, described below.

[0028] As shown in Fig. 4, the outer shape of the top portion 321 when viewed from above is approximately circular. As shown in Fig. 2, the outer surface 321a of the top portion 321 is curved upward (spherical in this embodiment). In other words, the outer surface 321a of the top portion 321 is curved in a direction away from the bottom portion 31 (spherical in this embodiment). The curvature of the outer surface 321a of the top portion 321 changes continuously. In other words, the outer surface 321a of the top portion 321 has no edges.

[0029] The outer peripheral portion 322 is a portion that continues from at least a portion of the area along the outer periphery of the top portion 321. An outer surface 322a of the outer peripheral portion 322 is a curved surface (spherical in this embodiment) that continues from the outer surface 321a of the top portion 321. The outer peripheral portion 322 is continuous with the bottom portion 31 on the side opposite to the top portion 321.

[0030] As shown in Fig. 3, the recess 33 is a portion recessed from the lower surface 31a of the bottom 31 toward the inside of the bulge 32. In other words, the recess 33 is a portion obtained by hollowing out the interior of the bulge 32 from the lower surface 31a of the bottom 31. As shown in Figs. 3, 5, and 6, the inner surface 33a of the recess 33 is curved toward the apex P1 of the bulge 32. In this embodiment, the distance between the inner surface 33a of the recess 33 and the outer surfaces 321a, 322a of the bulge 32 (i.e., the thickness of the material constituting the recess 33 and the bulge 32) is constant.

[0031] The reinforcing portion 34 is a portion that protrudes from the inner surface 33a of the recess 33. The reinforcing portion 34 is plate-shaped. In this embodiment, the reinforcing portion 34 is flat-plate-shaped. As shown in FIG. 5 , the reinforcing portion 34 protrudes from a range on the inner surface 33a of the recess 33 that overlaps with the apex 321 in the up-down direction. Specifically, the reinforcing portion 34 protrudes from a range on the inner surface 33a of the recess 33 that overlaps with the apex P1 of the apex 321 in the up-down direction. As shown in FIGS. 3 , 5 , and 6 , the reinforcing portion 34 extends in a direction from the first pressing portion 30 toward the second pressing portion 40. That is, the reinforcing portion 34 protrudes from a range on the inner surface 33a of the recess 33 that overlaps with a center line L3 (described later) in the up-down direction.

[0032] As shown in FIG. 6 , from the viewpoint of making it easier for the first pressing portion 30 to conform to the first region, the ratio H1 / D of the height H1 of the first pressing portion 30 to the overall length D of the medical care product 1A is preferably 0.2 or greater and 0.3 or less. The overall length D of the medical care product 1A is the dimension of the medical care product 1A in the direction from the first pressing portion 30 toward the second pressing portion 40. Specifically, the overall length D of the medical care product 1A is the dimension of the medical care product 1A along the center line L3 described below. However, this overall length D does not include the dimensions of the fitting portion 311 of the first pressing portion 30 and the fitting portion 411 of the second pressing portion 40 described below. Furthermore, the height H1 of the first pressing portion 30 here refers to the height H1 of the apex P1 of the bulge 32. When the first pressing portion 30 conforms more easily to the first region, the first pressing portion 30 presses the first region more easily.

[0033] 4 , from the viewpoint of making the bulging portion 32 more easily deflectable when sandwiched between the buttocks of a user such as a pregnant woman as described below, the ratio W1 / D of the maximum width W1 of the first pressing portion 30 to the overall length D of the medical care product 1A is preferably 0.4 or more and 0.6 or less. The maximum width W1 of the first pressing portion 30 is the maximum dimension of the first pressing portion 30 in a direction perpendicular to the direction from the first pressing portion 30 to the second pressing portion 40 as viewed from above. Specifically, the maximum width W1 of the first pressing portion 30 is the maximum dimension of the first pressing portion 30 in a direction perpendicular to a center line L3 (described below) of the first pressing portion 30 as viewed from above. When the bulging portion 32 is more easily deflected, the first pressing portion 30 is more easily able to press the first region.

[0034] (Second Pressing Portion) The second pressing portion 40 is a portion configured to press the second region. The second region is a region different from the first region described above. The second region is included in the range from the coccyx to the perineum. As shown in Figures 2 and 3 , the second pressing portion 40 has a bottom portion 41, a bulging portion 42, a recessed portion 43, and a reinforcing portion 44.

[0035] The bottom portion 41 is a portion that forms a flat lower surface 41 a. The lower surface 41 a of the bottom portion 41 corresponds to the lower surface of the second pressing portion 40.

[0036] An engaging portion 411 is provided on the outer surface 41b of the bottom portion 41. The engaging portion 411 is a portion that protrudes from the outer surface 41b of the bottom portion 41. As shown in FIG. 4 , the outer shape of the engaging portion 411 in a top view is the same as that of the engaging portion 311 of the first pressing portion 3. In this embodiment, the outer shape of the engaging portion 411 in a top view is roughly triangular. Furthermore, the size of the engaging portion 411 in a top view is equal to the size of the engaging portion 311 of the first pressing portion 3 in a top view. The engaging portion 411 is configured to be engageable with a fitted portion 622 (described later) of the blocking member 6.

[0037] 2, the bulging portion 42 is a portion that bulges upward from the bottom portion 41. In other words, the bulging portion 42 is a portion that bulges out from the bottom portion 41 toward the side opposite the lower surface 41a. The bulging portion 42 has an apex 421 and an outer periphery 422.

[0038] The apex 421 is a portion including the apex P2 of the bulging portion 42. As shown in FIG. 6, the apex P2 of the bulging portion 42 is the point at which the height H2 of the bulging portion 42 is the highest. As shown in FIG. 4, the outer shape of the apex 421 in a top view is approximately a perfect circle. As shown in FIG. 2, the outer surface 421a of the apex 421 is curved upward (spherical in this embodiment). In other words, the outer surface 421a of the apex 421 is curved in a direction away from the bottom 41 (spherical in this embodiment). The curvature of the outer surface 421a of the apex 421 changes continuously. In other words, the outer surface 421a of the apex 421 has no edges.

[0039] The outer peripheral portion 422 is a portion that continues from at least a portion of the area along the outer periphery of the top portion 421. An outer surface 422a of the outer peripheral portion 422 is curved (spherical in this embodiment) and continues from the outer surface 421a of the top portion 421. The outer peripheral portion 422 is continuous with the bottom portion 41 on the side opposite to the top portion 421.

[0040] As shown in Fig. 3, the recess 43 is a portion recessed from the lower surface 41a of the bottom 41 toward the inside of the bulge 42. In other words, the recess 43 is a portion obtained by hollowing out the interior of the bulge 42 from the lower surface 41a of the bottom 41. As shown in Figs. 3, 5, and 6, the inner surface 43a of the recess 43 is curved toward the apex P2 of the bulge 42. In this embodiment, the distance between the inner surface 43a of the recess 43 and the outer surfaces 421a, 422a of the bulge 42 (i.e., the thickness of the material constituting the recess 43 and the bulge 42) is constant.

[0041] The reinforcing portion 44 is a portion that protrudes from the inner surface 43a of the recess 43. The reinforcing portion 44 is plate-shaped. In this embodiment, the reinforcing portion 44 is flat-plate-shaped. As shown in FIG. 5 , the reinforcing portion 44 protrudes from a range on the inner surface 43a of the recess 43 that overlaps with the apex 421 in the up-down direction. Specifically, the reinforcing portion 44 protrudes from a range on the inner surface 43a of the recess 43 that overlaps with the apex P2 of the apex 421 in the up-down direction. As shown in FIGS. 3 , 5 , and 6 , the reinforcing portion 44 extends in a direction from the first pressing portion 30 toward the second pressing portion 40. That is, the reinforcing portion 44 protrudes from a range on the inner surface 43a of the recess 43 that overlaps with a center line L3 (described later) in the up-down direction.

[0042] As shown in Figure 6, the height H2 of the second pressing portion 40 is lower than the height H1 of the first pressing portion 30. Specifically, the height H2 of the apex P2 of the bulge 42 in the second pressing portion 40 is lower than the height H1 of the apex P1 of the bulge 32 in the first pressing portion 30. From the perspective of making it easier for the second pressing portion 40 to conform to the second region, it is preferable that the ratio H2 / D of the height H2 of the second pressing portion 40 to the overall length D of the medical care product 1A be 0.2 or greater and 0.3 or less. The height H2 of the second pressing portion 40 here refers to the height H2 of the apex P2 of the bulge 42. If the second pressing portion 40 conforms more easily to the second region, the second pressing portion 40 will more easily press the second region.

[0043] As shown in FIG. 4 , the maximum width W2 of the second pressing portion 40 is smaller than the maximum width W1 of the first pressing portion 30. The maximum width W2 of the second pressing portion 40 is the maximum dimension of the second pressing portion 40 in a direction perpendicular to the direction from the first pressing portion 30 to the second pressing portion 40 when viewed from above. Specifically, the maximum width W2 of the second pressing portion 40 is the maximum dimension of the second pressing portion 40 in a direction perpendicular to the center line L3 described below when viewed from above. From the perspective of making the bulging portion 42 more easily deflectable when sandwiched between the buttocks of a user, such as a pregnant woman, as described below, the ratio W2 / D of the maximum width W2 of the second pressing portion 40 to the total length D of the medical care product 1A is preferably 0.4 or more and 0.6 or less. If the bulging portion 42 is more easily deflectable, the second pressing portion 40 is more easily able to press the first region.

[0044] (Connecting Portion) The connecting portion 50 is a portion that connects the first pressing portion 30 and the second pressing portion 40. As shown in Figures 2 and 3 , the connecting portion 50 has a bottom portion 51, a bulging portion 52, a recessed portion 53, and a reinforcing portion 54.

[0045] The bottom portion 51 is a portion that connects the bottom portion 31 of the first pressing portion 30 and the bottom portion 41 of the second pressing portion 40. As shown in Fig. 3, the bottom portion 51 forms a flat lower surface 51a. The lower surface 51a of the bottom portion 51 corresponds to the lower surface of the connecting portion 50. The lower surface 51a of the bottom portion 51 is continuous with the lower surfaces 31a and 41a of the bottom portions 31 and 41 of the first pressing portion 30 and the second pressing portion 40, respectively, and forms a continuous flat surface together with these lower surfaces 31a and 41a.

[0046] 2, the bulging portion 52 is a portion that connects the bulging portion 32 of the first pressing portion 30 and the bulging portion 42 of the second pressing portion 40. The bulging portion 52 bulges upward from the bottom portion 51. In other words, the bulging portion 52 bulges from the bottom portion 51 toward the side opposite to the lower surface 51 a.

[0047] The outer surface 52a of the bulging portion 52 includes the upper surface of the connecting portion 50. The outer surface 52a of the bulging portion 52 is curved and has a first ridgeline L1 and a second ridgeline L2. The first ridgeline L1 is a ridgeline that continues from the bulging portion 32 of the first pressing portion 30 to the bulging portion 42 of the second pressing portion 40. As shown in FIG. 4, the first ridgeline L1 is linear in top view. As shown in FIG. 6, the first ridgeline L1 curves downward. As shown in FIG. 2, the second ridgeline L2 is a ridgeline that intersects with the first ridgeline L1. Specifically, as shown in FIG. 4, the second ridgeline L2 is a ridgeline that is perpendicular to the first ridgeline L1 in top view. The second ridgeline L2 is linear in top view. As shown in FIG. 7, the second ridgeline L2 curves upward.

[0048] The intersection P3 of the first ridge line L1 and the second ridge line L2 shown in Figure 2 and other figures coincides with the lowest point of the first ridge line L1, as shown in Figure 6. As shown in Figure 7, the intersection P3 coincides with the highest point of the second ridge line L2. As shown in Figures 2, 6, and 7, the height of the outer surface 52a of the bulging portion 52 is lower over the entire area than both the vertex P1 of the first pressing portion 30 and the vertex P2 of the second pressing portion 40.

[0049] As shown in FIGS. 1 , 2 , and 4 , a line passing through the vertex P1 of the first pressing portion 30 and the vertex P2 of the second pressing portion 40 on the outer surface of the main body member 2 and linear in top view is referred to as the center line L3 below. The outer surface of the main body member 2 includes the outer surfaces 321a and 322a of the first pressing portion 30, the outer surfaces 421a and 422a of the second pressing portion 40, and the outer surface 52a of the connecting portion 50. As shown in FIG. 4 , the vertex P1 of the first pressing portion 30, the vertex P2 of the second pressing portion 40, and the intersection P3 between the first ridge line L1 and the second ridge line L2 are all aligned on the same straight line in top view. That is, the center line L3 passes through the vertex P1 of the first pressing portion 30, the vertex P2 of the second pressing portion 40, and the intersection P3 between the first ridge line L1 and the second ridge line L2. The center line L3 includes the first ridge line L1. The fitting portions 311 and 411 are provided at positions that overlap the center line L3 in the up-down direction.

[0050] 2 , the outer surface 52a of the bulging portion 52 is continuous with the outer surfaces 321a, 322a of the bulging portion 32 of the first pressing portion 30 and the outer surfaces 421a, 422a of the bulging portion 42 of the second pressing portion 40, and together with these outer surfaces 321a, 322a, 421a, 422a, forms a continuous curved surface whose curvature changes continuously. In other words, the outer surface 52a of the bulging portion 52 has no edges. Furthermore, there are no edges at the boundaries between the outer surface 52a of the bulging portion 52 and the outer surfaces 321a, 322a of the bulging portion 32 of the first pressing portion 30 or the outer surfaces 421a, 422a of the bulging portion 42 of the second pressing portion 40.

[0051] 3, the recess 53 is a portion recessed from the lower surface 51a of the bottom 51 toward the inside of the bulge 52. In other words, the recess 53 is a portion obtained by hollowing out the inside of the bulge 52 from the lower surface 51a of the bottom 51.

[0052] In the connecting portion 50, the recess 53 may be provided, for example, separate from the recesses 33, 43 of the first pressing portion 30 and the second pressing portion 40, but in this embodiment, the recess 53 is provided so as to connect these recesses 33, 43 (i.e., continuous with these recesses 33, 43). An inner surface 53a of the recess 53 is continuous with the inner surfaces 33a, 43a of the recesses 33, 43 of the first pressing portion 30 and the second pressing portion 40, respectively.

[0053] The reinforcing portion 54 is a portion that protrudes from the inner surface 53a of the recess 53. The reinforcing portion 54 is plate-shaped. In this embodiment, the reinforcing portion 54 is flat-plate-shaped. As shown in FIG. 5 , the reinforcing portion 54 protrudes from a range on the inner surface 53a of the recess 53 that overlaps in the up-down direction with the intersection P3 of the first ridge line L1 and the second ridge line L2. As shown in FIGS. 3 , 5 , and 6 , the reinforcing portion 54 extends in a direction from the first pressing portion 30 toward the second pressing portion 40. In other words, the reinforcing portion 44 protrudes from a range on the inner surface 53a of the recess 53 that overlaps in the up-down direction with the center line L3.

[0054] When the recess 53 of the connecting portion 50 is provided to connect the recess 33 of the first pressing portion 30 and the recess 43 of the second pressing portion 40 as in the present embodiment, the reinforcing portion 54 of the connecting portion 50 may be provided, for example, spaced apart from the reinforcing portions 34, 44 of the first pressing portion 30 and the second pressing portion 40, respectively, or may be provided to connect these reinforcing portions 34, 44 (i.e., continuous with these reinforcing portions 34, 44). In the present embodiment, the reinforcing portion 54 of the connecting portion 50 is provided to connect the reinforcing portion 34 of the first pressing portion 30 and the reinforcing portion 44 of the second pressing portion 40. The reinforcing portion 54 of the connecting portion 50, together with the reinforcing portion 34 of the first pressing portion 30 and the reinforcing portion 44 of the second pressing portion 40, constitute a single flat plate.

[0055] 4, the minimum width W3 of the connecting portion 50 is smaller than both the maximum width W1 of the first pressing portion 30 and the maximum width W2 of the second pressing portion 40. The minimum width W3 of the connecting portion 50 is the minimum dimension in a direction perpendicular to the center line L3 of the connecting portion 50 in a top view. The main body member 2 has a so-called gourd (peanut) shape in which the connecting portion 50 is constricted relative to the first pressing portion 30 and the second pressing portion 40 in a top view.

[0056] (Compressive Deformation Amount of Main Body Member) As described above, the main body member 2 is flexible. When the medical care product 1A is used for strain relief, the compressive deformation amount when the main body member 2 is compressed from above at a compression speed of 5 mm / min and a maximum compression load of 200 N is preferably 7 mm or more and 30 mm or less, more preferably 8 mm or more and 23 mm or less, and even more preferably 9 mm or more and 15 mm or less. The compressive deformation amount can be measured using a universal testing machine, Autograph AG-50KNX, manufactured by Shimadzu Corporation. Compressing the main body member 2 from above, more specifically, refers to pressing the first pressing portion 30 from above toward the bottom portion 31 with the blocking member 6 attached to the main body member 2.

[0057] <Closing Member> The closing member 6 shown in FIGS. 1 to 3 is a member configured to close the openings of the recesses 33, 43, and 53 of the main body member 2. The closing member 6 is, for example, flexible. The closing member 6 is made of, for example, resin. The closing member 6 is manufactured by, for example, injection molding. The closing member 6 is configured to be reusable, for example. In this case, the closing member 6 is configured to be resistant to, for example, disinfectant such as ethanol and hot water. In other words, the closing member 6 is configured to be sterilizable, for example. The closing member 6 includes a plate-shaped portion 61, an outer wall portion 62, an inner wall portion 63, and a plurality of protrusions 64.

[0058] As shown in FIG. 2 , the plate-shaped portion 61 is a plate-shaped portion. In this embodiment, the plate-shaped portion 61 is flat. Hereinafter, of both surfaces of the plate-shaped portion 61, the surface configured to face the main body member 2 when the blocking member 6 is attached to the main body member 2 will be referred to as the upper surface 61a of the plate-shaped portion 61. Furthermore, of both surfaces of the plate-shaped portion 61, the surface opposite the upper surface 61a will be referred to as the lower surface 61b of the plate-shaped portion 61, as shown in FIG. 3 . The plate-shaped portion 61 has a size that can cover the openings of the recesses 33, 43, and 53. The outer shape of the plate-shaped portion 61 in a top view (i.e., the outer shape as viewed from the upper surface 61a) is the same as or larger than the opening surfaces of the recesses 33, 43, and 53.

[0059] As shown in Fig. 2, the outer wall portion 62 is a portion that protrudes from the upper surface 61a of the plate-shaped portion 61. The protruding direction of the outer wall portion 62 is perpendicular to the upper surface 61a of the plate-shaped portion 61. The outer wall portion 62 is provided around the entire outer edge of the plate-shaped portion 61. The outer wall portion 62 is configured to contact the bottom portions 31, 41, 51 from the outside of the main body member 2. The inner peripheral surface 62a of the outer wall portion 62 is formed in a shape that corresponds to the outer surfaces 31b, 41b, 51b of the bottom portions 31, 41, 51.

[0060] Portions of the outer wall portion 62 that face the fitting portions 311, 411 when the blocking member 6 is attached to the main body member 2 form fitted portions 621, 622. The fitted portions 621, 622 are configured so that the fitting portions 311, 411 are fitted inside. In this embodiment, corresponding to the fitting portions 311, 411 that are generally triangular in shape when viewed from above, the fitted portions 621, 622 are generally L-shaped and protrude outward from the plate-like portion 61 when viewed from above.

[0061] The inner wall portion 63 is a portion that protrudes from the upper surface 61 a of the plate-shaped portion 61 in parallel to the outer wall portion 62. The inner wall portion 63 is provided inside the outer wall portion 62 and along the entire circumference of the outer wall portion 62. The outer peripheral surface 63 a of the inner wall portion 63 faces the inner peripheral surface 62 a of the outer wall portion 62 with a gap therebetween. The inner wall portion 63 is configured to be inserted into the recesses 33, 43, and 53 when the blocking member 6 is attached to the main body member 2 so that the outer wall portion 62 contacts the bottom portions 31, 41, and 51 from the outside of the main body member 2. Specifically, the inner wall portion 63 is configured to be inserted into the recesses 33, 43, and 53 while contacting the inner surfaces 33 a, 43 a, and 53 a of the recesses 33, 43, and 53. The outer peripheral surface 63 a of the inner wall portion 63 is formed in a shape corresponding to the inner surfaces 33 a , 43 a , 53 a of the recesses 33 , 43 , 53 .

[0062] As shown in FIG. 3 , each of the multiple protrusions 64 protrudes from and extends along the lower surface 61b of the plate-shaped portion 61. All of the multiple protrusions 64 extend linearly. The multiple protrusions 64 extend in a direction perpendicular to the direction from the first pressing portion 30 toward the second pressing portion 40 when the blocking member 6 is attached to the main body member 2. The end surfaces 64a of the multiple protrusions 64 are all flat. The end surface 64a of the protrusions 64 here refers to the surface at the tip of the protrusion 64 in the protruding direction (i.e., the surface opposite the lower surface 61b). The multiple protrusions 64 are arranged at intervals from one another.

[0063] [1-2. How to Use the Medical Care Product] An exemplary method of use when a pregnant woman uses the medical care product 1A herself to relieve straining is described below. The medical care product 1A includes a main body member 2 and a blocking member 6. For example, the medical care product 1A may be used with only the main body member 2, or with the blocking member 6 attached to the main body member 2. Hereinafter, the pregnant woman using the medical care product 1A will also be referred to as the "user."

[0064] When using the main body member 2 with the blocking member 6 attached, the user first attaches the blocking member 6 to the main body member 2. The user attaches the blocking member 6 to the main body member 2 with the upper surface 61a facing the recesses 33, 43, and 53 of the main body member 2. Specifically, the user attaches the blocking member 6 to the main body member 2 so that the outer wall portion 62 contacts the bottom portions 31, 41, and 51 from the outside of the main body member 2 and the inner wall portion 63 is inserted into the recesses 33, 43, and 53. At this time, the user fits the fitting portions 311 and 411 inside the fitted portions 621 and 622 of the blocking member 6, which makes it difficult for the blocking member 6 to come off the main body member 2.

[0065] When the closing member 6 is attached to the main body member 2, the openings of the recesses 33, 43, and 53 are closed by the plate-like portion 61. A closed space is formed inside the bulging portions 32, 42, and 52 by the plate-like portion 61 and the recesses 33, 43, and 53. At this time, for example, a hot / cold agent, an aromatic, a deodorizer, or the like may be placed in the space. Specific examples of hot / cold agents include ice packs and disposable hand warmers. Specific examples of aromatic agents include potpourri. Specific examples of deodorizers include highly absorbent polymers. Note that, later, configurations in which hot / cold agents 8 and 8D are placed inside the bulging portions 32, 42, and 52 will be described in detail for a medical care product 1C of a third embodiment and a medical care product 1D of a fourth embodiment.

[0066] Next, the user places the main body member 2 with the blocking member 6 attached on the placement surface S, as shown in Fig. 6. Specifically, the user places the main body member 2 with the blocking member 6 attached on the placement surface S so that the end faces 64a of the multiple protrusions 64 contact the placement surface S. Specific examples of the placement surface S include the seat of a chair, the surface of a bed, and the floor. From the viewpoint of the stability of the medical care product 1A on the placement surface S, it is preferable that the placement surface S be, for example, flat.

[0067] On the other hand, when the user uses the main body member 2 alone, the user places the main body member 2 alone on the placement surface S. Specifically, the user places the main body member 2 on the placement surface S so that the lower surfaces 31 a, 41 a, 51 a of the bottom portions 31, 41, 51 contact the placement surface S.

[0068] The user places the main body member 2 on the placement surface S, either alone or with the blocking member 6 attached, and then sits on the main body member 2. Specifically, the user sits on the main body member 2 so that the first region contacts the first pressing portion 30 and the second region contacts the second pressing portion 40. As a result, the first region is pressed by the first pressing portion 30 and the second region is pressed by the second pressing portion 40 due to the user's own weight. Pressing the first region and the second region makes it easier for the user to relieve straining.

[0069] [1-3. Effects] According to the first embodiment described above in detail, the following effects are achieved.

[0070] (1a) The medical care product 1A includes a first pressing portion 30 and a second pressing portion 40. The first pressing portion 30 and the second pressing portion 40 each have a bottom portion 31, 41 and a bulge portion 32, 42. The first pressing portion 30 and the second pressing portion 40 are connected to each other by a connecting portion 50.

[0071] According to this configuration, the first region and the second region can be easily pressed simultaneously by the first pressing portion 30 and the second pressing portion 40. Therefore, it is possible to make it easier for the user to relieve straining.

[0072] (1b) Furthermore, with the above-described configuration, the connecting portion 50 can easily maintain a constant position of the second pressing portion 40 relative to the first pressing portion 30. This makes it difficult for the pressing positions of the first pressing portion 30 and the second pressing portion 40 to shift. This makes it easier to more reliably press not only the first region but also, for example, the second region according to the user's desire.

[0073] (1c) The lower surfaces 31 a, 41 a of the bottoms 31, 41 of the first pressing portion 30 and the second pressing portion 40, respectively, are flat. With this configuration, for example, when the main body member 2 is used alone, the stability of the first pressing portion 30 and the second pressing portion 40 on the placement surface S can be improved.

[0074] (1d) The bulging portions 32, 42 of the first pressing portion 30 and the second pressing portion 40 each have a peak 321, 421. The outer surfaces 321a, 421a of the peaks 321, 421 are curved upward. This configuration makes it easier to press the first region and the second region overall rather than locally.

[0075] (1e) The connecting portion 50 connects the bulging portions 32, 42 of the first pressing portion 30 and the second pressing portion 40. The upper surface of the connecting portion 50 is curved and has a first ridge line L1 and a second ridge line L2. This configuration makes it easier for the connecting portion 50 to come into contact with the region between the first region and the second region.

[0076] (1f) The first pressing portion 30 and the second pressing portion 40 each further include a recess 33, 43. The recess 33, 43 is recessed from the lower surface 31a, 41a of the bottom portion 31, 41 toward the inside of the bulge portion 32, .

[0077] With this configuration, for example, when a user sits on the first pressing portion 30 and the second pressing portion 40 and the bulging portions 32, 42 are sandwiched between the user's buttocks, the bulging portions 32, 42 can be easily deflected. The deflection of the bulging portions 32, 42 makes it even easier to press the first region and the second region.

[0078] (1g) In particular, in this embodiment, the connecting portion 50 also has a recess 53. The recess 53 of the connecting portion 50 is provided so as to connect the recess 33 of the first pressing portion 30 and the recess 43 of the second pressing portion 40. This configuration can further enhance the effect of making the bulging portions 32, 42 more easily deflectable, as described in (1f) above.

[0079] (1h) The first pressing portion 30 and the second pressing portion 40 each further include a reinforcing portion 34, 44. This configuration allows the bulging portions 32, 42 to bend easily while increasing the strength of the portions of the bulging portions 32, 42 that overlap the reinforcing portion 34, 44 in the vertical direction. This makes it even easier to press the first region and the second region.

[0080] (1i) In particular, in this embodiment, the reinforcing portions 34, 44 protrude from the area of ​​the inner surface 33a, 43a of the recess 33, 43 that overlaps with the apex 321, 421 in the vertical direction. This configuration increases the strength of the apex 321, 421 while realizing the flexibility of the bulge 32, 42. This makes it particularly easy to simultaneously press the first region and the second region. This is because the apex 321, 421 is the portion of the bulge 32, 42 that is most likely to come into contact with the first region or the second region.

[0081] (1j) The height H1 of the first pressing portion 30 is greater than the height H2 of the second pressing portion 40. This configuration makes it easier for the first pressing portion 30 and the second pressing portion 40 to come into contact with the first region and the second region. Therefore, it is easier to press the first region and the second region.

[0082] (1k) The medical care product 1A further includes a blocking member 6. The blocking member 6 is configured to block the recesses 33, 43, and 53.

[0083] With this configuration, the closing member 6 and the recesses 33, 43, 53 can form a closed space inside the bulging portions 32, 42, 52. For example, by placing a hot or cold agent in the space, it is possible to warm or cool the bulging portions 32, 42, 52. Also, for example, by placing an aromatic agent in the space, it is possible to help the user relax.

[0084] [2. Second embodiment] [2-1. Configuration of the medical care product] The second embodiment has the same basic configuration as the first embodiment, so differences will be described below. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and reference is made to the preceding description.

[0085] The medical care product 1A of the first embodiment described above includes a main body member 2 and a blocking member 6. In contrast, the medical care product 1B of the second embodiment shown in Fig. 8 includes a main body member 2 and an auxiliary member 7.

[0086] The auxiliary member 7 is attached to the main body member 2 and configured to be held by an assistant. The assistant refers to a person who assists the pregnant woman who is trying to relieve strain. Specific examples of the assistant include the pregnant woman's partner and a nurse.

[0087] The auxiliary member 7 is made of, for example, resin and has a fitting portion 71 and a grip portion 72 .

[0088] The fitting portion 71 is configured to fit into the recesses 33, 43, 53 of the main body member 2. As shown in FIG.

[0089] The base portion 711 is a plate-shaped portion. The base portion 711 in this embodiment is in the shape of a flat plate.

[0090] The bulging portion 712 is a portion that bulges out from the base portion 711 toward one side of the base portion 711. The outer surface 712a of the bulging portion 712 is formed in a shape that corresponds to the inner surfaces 33a, 43a, and 53a of the recesses 33, 43, and 53. In this embodiment, the outer surface 712a of the bulging portion 712 is curved in a direction away from the base portion 711.

[0091] In this embodiment, the reinforcing portions 34, 44, 54 are disposed in the recesses 33, 43, 53. For this reason, grooves 713 configured to allow the insertion of the reinforcing portions 34, 44, 54 are formed on the outer surface 712a of the bulging portion 712 in this embodiment. The grooves 713 are formed as linearly extending recesses corresponding to the flat plate-shaped reinforcing portions 34, 44, 54.

[0092] The grip portion 72 is a portion configured to be gripped by an assistant. The grip portion 72 is provided in the fitting portion 71. Specifically, the grip portion 72 is provided on the surface of the base portion 711 opposite the bulging portion 712 side. The grip portion 72 of this embodiment is formed in a rod shape that is curved in a direction away from the base portion 711. Both axial ends of the grip portion 72 are fixed to the base portion 711. A gap is provided between the axial middle portion of the grip portion 72 and the base portion 711. The axial middle portion of the grip portion 72 refers to the portion between one axial end and the other axial end of the grip portion 72.

[0093] [2-2. How to use the medical care product] As with the medical care product 1A of the first embodiment, the medical care product 1B of the second embodiment can also be used by a pregnant woman to relieve straining by, for example, placing the main body member 2 alone on the placement surface S and sitting on it.

[0094] In addition, the medical care product 1B of the second embodiment can also be used by an assistant to assist a pregnant woman in releasing straining. An exemplary method of use in which an assistant uses the medical care product 1B to assist a pregnant woman in releasing straining will be described below. The pregnant woman being assisted will also be referred to as the subject below.

[0095] First, the assistant or the subject attaches the auxiliary member 7 to the main body member 2. Specifically, the assistant or the subject fits the fitting portion 71 of the auxiliary member 7 into the recesses 33, 43, and 53 of the main body member 2. This positions the fitting portion 71 inside the main body member 2 and the grip portion 72 outside the main body member 2 (more specifically, outside the bottom portions 31, 41, and 51).

[0096] Next, the assistant grasps the gripping portion 72. The subject lies on their side on a bed, for example. The assistant then faces the main body member 2 of the medical care product 1B toward the subject and moves the medical care product 1B so that the first pressing portion 30 contacts the first region and the second pressing portion 40 contacts the second region. Then, with the first pressing portion 30 contacting the first region and the second pressing portion 40 contacting the second region, the assistant applies force to the medical care product 1B toward the subject. As a result, the first region is pressed by the first pressing portion 30, and the second region is pressed by the second pressing portion 40. Pressing the first region and the second region makes it easier for the subject to relieve straining.

[0097] [2-3. Effects] This configuration provides the same effects as those (1a) to (1j) above, and also provides the following effects.

[0098] The medical care product 1B further includes an auxiliary member 7. The auxiliary member 7 has an insertion portion 71 and a gripping portion 72. With this configuration, the auxiliary member 7 can be attached to the main body member 2 by inserting the insertion portion 71 into the recesses 33, 43, and 53. Then, by gripping the gripping portion 72, an assistant can easily support the main body member 2 with the auxiliary member 7 attached. Therefore, it is easy for the assistant to use the medical care product 1B to assist the pregnant woman in relieving straining.

[0099] [3. Third embodiment] [3-1. Configuration of the medical care product] The third embodiment has the same basic configuration as the first embodiment, so differences will be described below. Note that the same reference numerals as those in the first embodiment indicate the same configuration, and reference is made to the preceding description.

[0100] The medical care product 1A of the first embodiment described above includes a main body member 2 and a blocking member 6. In contrast, the medical care product 1C of the third embodiment shown in Fig. 10 includes a hot / cold agent 8 in addition to the main body member 2 and the blocking member 6. Note that Fig. 11 is a bottom view of the main body member 2 with the hot / cold agent 8 disposed therein as shown in Fig. 10, but for ease of explanation, the hot / cold agent 8 is shown as being transparent.

[0101] The hot / cold agent 8 is a member configured to be able to keep things hot and cold. The hot / cold agent 8 is configured, for example, to be reusable. In other words, the hot / cold agent 8 is configured, for example, to be able to be heated or cooled repeatedly. As shown in Figures 12 to 14, the hot / cold agent 8 has an exterior body 81 and a content 82.

[0102] The exterior body 81 is a member having a space formed therein. The material of the exterior body 81 is, for example, a polymer, a nonwoven fabric, or the like. The exterior body 81 may or may not be flexible. In other words, the exterior body 81 may be a so-called hard type that maintains a predetermined shape, or a so-called soft type that deforms in response to an external force.

[0103] The contents 82 are contained (e.g., filled) inside the exterior body 81. The contents 82 exhibit both heat retention and cold retention functions. In this embodiment, the contents 82 are a highly water-absorbent polymer that has absorbed water. A highly water-absorbent polymer is a polymer that can absorb 100 to 1000 times its own weight in water. Specific examples of highly water-absorbent polymers include sodium polyacrylate and crosslinked acrylamide.

[0104] 10 to 14, the hot / cold agent 8 is disposed inside the main body member 2. Specifically, the hot / cold agent 8 is disposed in the recesses 33, 43, and 53. The hot / cold agent 8 is disposed so as to come into contact with at least the hot / cold range R on the inner surfaces 33a, 43a, and 53a of the recesses 33, 43, and 53. As shown in FIG. 11, the hot / cold range R is a line segment on the center line L3 that overlaps in the vertical direction with the line segment from the vertex P1 of the first pressing portion 30 to the vertex P2 of the second pressing portion 40. In the present embodiment, when reinforcing portions 34, 44, 54 are provided on the inner surfaces 33a, 43a, 53a of the recesses 33, 43, 53 in the range that overlaps vertically with the center line L3, as shown in Figures 12 to 14, contact with the end of the surface of the reinforcing portions 34, 44, 54 on the inner surface 33a, 43a, 53a side of the recesses 33, 43, 53 is treated as contact with the hot / cold range R.

[0105] As shown in Figures 10 to 14, in this embodiment, the hot / cold agent 8 is arranged to fill the recesses 33, 43, and 53. That is, the hot / cold agent 8 is in contact with the entire inner surfaces 33a, 43a, and 53a of the recesses 33, 43, and 53. When the exterior body 81 is a hard type, the exterior body 81 is formed into an outer shape that corresponds to the internal space of the recesses 33, 43, and 53, thereby realizing a configuration in which the hot / cold agent 8 fills the recesses 33, 43, and 53. On the other hand, when the exterior body 81 is a soft type, the exterior body 81 has the same volume as the internal space of the recesses 33, 43, and 53, and an external force causes the exterior body 81 to deform so as to conform to the internal surfaces 33a, 43a, and 53a of the recesses 33, 43, and 53, thereby realizing a configuration in which the hot / cold agent 8 fills the recesses 33, 43, and 53.

[0106] [3-2. How to Use the Medical Care Product] The medical care product 1C of the third embodiment can be used in the same manner as the medical care product 1A of the first embodiment described above.

[0107] Specifically, the user first places a preheated or precooled hot / cold agent 8 inside the main body member 2. Whether the hot / cold agent 8 is preheated or precooled can be selected according to the user's preference, but according to the applicant's investigations, when the medical care product 1C is used for strain relief, a preheated hot / cold agent 8 is often selected.

[0108] Next, the user attaches the blocking member 6 to the main body member 2 containing the hot / cold agent 8. The specific method for attaching the blocking member 6 to the main body member 2 and the subsequent procedure for using the medical care product 1C are as described in the first embodiment.

[0109] In the medical care product 1C of this embodiment, heat is conducted between the main body member 2 and the hot / cold agent 8 disposed therein. If the hot / cold agent 8 is preheated, the main body member 2 is warmed. If the hot / cold agent 8 is precooled, the main body member 2 is cooled. With the main body member 2 in a heated or cooled state, labor pains tend to be alleviated when the user sits on the main body member 2. This makes it easier for the user to push through.

[0110] [3-3. Effects] According to this configuration, the same effects as those of the first embodiment described above are achieved, and further, the following effects are achieved.

[0111] (3a) The medical care product 1C further includes a hot / cold agent 8. The hot / cold agent 8 is disposed inside the main body member 2. With this configuration, the main body member 2 can be heated or cooled by the hot / cold agent 8. Therefore, by using the medical care product 1C, the user can more easily relieve labor pains. This in turn makes it easier to relieve straining.

[0112] (3b) The hot / cold agent 8 is disposed in the recessed portion 33, 43, 53. The hot / cold agent 8 is disposed so as to contact at least the hot / cold range R on the inner surface 33a, 43a, 53a of the recessed portion 33, 43, 53.

[0113] With this configuration, the area on the outer surface of the main body member 2, which includes a line segment on the center line L3 from the apex P1 of the first pressing portion 30 to the apex P2 of the second pressing portion 40, can be particularly heated or cooled by the hot / cold agent 8. This area on the outer surface of the main body member 2 is particularly likely to come into contact with the user when the user sits on the main body member 2. Therefore, by using the medical care product 1C, the user can more easily relieve labor pains. This in turn makes it even easier to relieve pushing pains.

[0114] (3c) In particular, in this embodiment, the hot / cold agent 8 is arranged so as to contact the entire inner surface 33a, 43a, 53a of the recess 33, 43, 53. With this configuration, the hot / cold agent 8 can heat or cool the entire outer surface of the main body member 2. Therefore, by using the medical care product 1C, the user can further ease labor pains. This in turn makes it even easier to relieve straining.

[0115] [4. Fourth embodiment] [4-1. Configuration of the medical care product] The fourth embodiment has the same basic configuration as the third embodiment, so differences will be described below. Note that the same reference numerals as those in the third embodiment indicate the same configuration, and reference is made to the preceding description.

[0116] The fourth embodiment of the medical care product 1D shown in Figure 15 differs from the third embodiment of the medical care product 1C in that it has a main body member 2D and a hot / cold agent 8D instead of the main body member 2 and hot / cold agent 8 described above.

[0117] The main body member 2D has substantially the same configuration as the above-described main body member 2. However, the main body member 2D does not have the reinforcing portions 34, 44, 54.

[0118] The hot / cold agent 8D has substantially the same configuration as the above-described hot / cold agent 8. However, as shown in Figures 16 to 18, the volume of the hot / cold agent 8D is smaller than the volume of the space inside the recesses 33, 43, and 53. When the medical care product 1D is placed on the placement surface S, the hot / cold agent 8D is placed with a gap between it and at least a part of the inner surface 33a, 43a, and 53a of the recesses 33, 43, and 53.

[0119] For example, when the medical care product 1D is placed on the placement surface S, the hot / cold agent 8D may be placed at a distance from the hot / cold range R on the inner surfaces 33a, 43a, 53a of the recesses 33, 43, 53 (i.e., not in contact with the hot / cold range R). Also, when the medical care product 1D is placed on the placement surface S, the hot / cold agent 8D may be placed at a distance from the entire inner surfaces 33a, 43a, 53a of the recesses 33, 43, 53 (i.e., not in contact with the inner surfaces 33a, 43a, 53a). Even when the hot / cold agent 8D is not in contact with the inner surfaces 33a, 43a, 53a of the recesses 33, 43, 53, the hot / cold agent 8D is heated or cooled by heat transfer through the air between the hot / cold agent 8D and the inner surfaces 33a, 43a, 53a of the recesses 33, 43, 53.

[0120] 4-2. How to Use the Medical Care Product The medical care product 1D of the fourth embodiment can be used in the same manner as the medical care product 1C of the third embodiment described above.

[0121] [4-3. Effects] According to this configuration, the same effects as those of (1a) to (1k) and (3a) above are achieved, and further, the following effects are achieved.

[0122] (4a) The hot / cold agent 8D is disposed with a gap between it and at least a part of the inner surface 33 a, 43 a, 53 a of the recess 33, 43, 53. This configuration can prevent the main body member 2 from being heated or cooled too much.

[0123] (4b) For example, the hot / cold agent 8D may be disposed at a distance from the hot / cold range R on the inner surface 33 a, 43 a, 53 a of the recess 33, 43, 53. In this case, it is possible to prevent the outer surface of the main body member 2, particularly the range including the line segment on the center line L3 from the vertex P1 of the first pressing portion 30 to the vertex P2 of the second pressing portion 40, from being heated or cooled too much.

[0124] 5. Other Embodiments Although the embodiments of the present disclosure have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take on various forms.

[0125] (5a) In the above embodiment, the lower surfaces 31 a, 41 a of the bottom portions 31, 41 of the first pressing portion 30 and the second pressing portion 40, respectively, are flat. However, the shape of the lower surfaces of the bottom portions is not particularly limited. For example, the lower surfaces of the bottom portions may be partially curved. Furthermore, for example, the shape of the lower surfaces of the bottom portions of the first pressing portion and the second pressing portion may be the same as in the above embodiment, or may be different from each other.

[0126] (5b) In the above embodiment, the outer shape of the apex 321, 421 of each of the first pressing portion 30 and the second pressing portion 40 in a top view is generally circular. However, the outer shape of the apex in a top view is not particularly limited and may be, for example, elliptical or oval. Furthermore, for example, the outer shape of the apex of the first pressing portion and the outer shape of the apex of the second pressing portion may be the same as in the above embodiment, or may be different from each other.

[0127] (5c) In the above embodiment, the outer surfaces 321 a, 421 a of the apexes 321, 421 of the first pressing portion 30 and the second pressing portion 40, respectively, are curved upward. However, the shape of the outer surfaces of the apexes is not particularly limited. For example, a portion of the outer surface of the apex may be flat. Furthermore, for example, the shape of the outer surface of the apex of the first pressing portion and the shape of the outer surface of the apex of the second pressing portion may be the same as in the above embodiment, or may be different from each other.

[0128] (5d) In the fourth embodiment, the main body member 2D does not have a reinforcing portion. However, as in the first to third embodiments, a reinforcing portion may be provided in at least one of the first pressing portion 30, the second pressing portion 40, and the connecting portion 50. In this case, the reinforcing portion can prevent the hot / cold agent 8D from moving in a direction approaching the hot / cold range R. Therefore, the hot / cold agent 8D can be prevented from coming into contact with the hot / cold range R. In other words, the effect of (4b) above can be more easily achieved.

[0129] (5e) In the above embodiment, both the first pressing portion 30 and the second pressing portion 40 have the recesses 33, 43, but, for example, at least one of the first pressing portion and the second pressing portion does not have to have a recess. In other words, in the above embodiment, the first pressing portion 30 and the second pressing portion 40 are so-called hollow portions, but, for example, the first pressing portion and the second pressing portion may be so-called solid portions. Similarly, the connecting portion does not necessarily have to have a recess as in the above embodiment.

[0130] (5f) In the above embodiment, the upper surface of the connecting portion 50 is curved and has a first ridgeline L1 and a second ridgeline L2. However, the shape of the upper surface of the connecting portion is not particularly limited. For example, the upper surface of the connecting portion may be curved and have ridgelines different from the first ridgeline L1 and the second ridgeline L2. Alternatively, for example, at least a portion of the upper surface of the connecting portion may be flat.

[0131] (5g) In the above embodiment, the bottom 51 of the connecting portion 50 connects the bottoms 31, 41 of the first pressing portion 30 and the second pressing portion 40, and the bulging portion 52 of the connecting portion 50 connects the bulging portions 32, 42 of the first pressing portion 30 and the second pressing portion 40. That is, in the above embodiment, the connecting portion 50 connects both the bottoms 31, 41 and the bulging portions 32, 42 of the first pressing portion 30 and the second pressing portion 40.

[0132] However, the connecting portion may connect any portion of the first pressing portion and the second pressing portion. For example, the connecting portion may connect only the bulging portions of the first pressing portion and the second pressing portion, or may connect only the bottom portions of the first pressing portion and the second pressing portion. Furthermore, for example, when the connecting portion connects only the bulging portions of the first pressing portion and the second pressing portion, the lower surface of the connecting portion does not necessarily have to be flat as in the above embodiment.

[0133] (5h) For example, the connecting portion may be configured to maintain a constant distance between the first pressing portion and the second pressing portion, as in the above embodiment, or may be configured to change the distance between the first pressing portion and the second pressing portion. A specific example of a connecting portion configured to change the distance between the first pressing portion and the second pressing portion is a connecting portion having a bellows-shaped portion. When the connecting portion is configured to change the distance between the first pressing portion and the second pressing portion, the first region and the second region can be more reliably pressed by adjusting the distance to suit the physique of the pregnant woman.

[0134] (5i) In the above embodiment, the height H1 of the first pressing portion 30 is greater than the height H2 of the second pressing portion 40. However, the height of the first pressing portion relative to the second pressing portion is not particularly limited. For example, the height of the first pressing portion may be the same as the height of the second pressing portion.

[0135] (5j) In the above embodiment, the main body member 2 includes the first pressing portion 30 and the second pressing portion 40. However, the number of pressing portions included in the main body member is not particularly limited, and may be, for example, two as in the above embodiment, or three or more.

[0136] (5k) When the medical care product includes a blocking member as in the first, third, and fourth embodiments, the blocking member may be formed in any shape capable of blocking the opening of the recess 33, 43, or 53. However, from the viewpoint of stability on the placement surface S of the main body member when the blocking member is attached, it is preferable that the blocking member have a flat contact surface on the side opposite to the main body member. In the blocking member 6 of the first, third, and fourth embodiments, the end faces 64a of the multiple protrusions 64 correspond to the contact surface.

[0137] (5l) In the first, third, and fourth embodiments, the multiple protrusions 64 are portions that extend linearly in a direction perpendicular to the direction from the first pressing portion 30 toward the second pressing portion 40 when the blocking member 6 is attached to the main body member 2. However, the direction in which the multiple protrusions extend is not particularly limited. For example, the multiple protrusions may be portions that extend in a direction from the first pressing portion toward the second pressing portion when the blocking member is attached to the main body member. Furthermore, the multiple protrusions do not necessarily have to be linear; for example, at least a portion of the protrusions may be curved.

[0138] For example, the blocking member may be provided with a columnar portion in addition to or instead of the ridges. The columnar portion is a columnar portion, such as a cylindrical portion, that protrudes from the underside of the plate-like portion. For example, the blocking member does not need to be provided with a protruding portion, such as a ridge or a columnar portion, that protrudes from the underside of the plate-like portion.

[0139] (5m) In the first, third, and fourth embodiments, the closure member 6 is configured to close the openings of the three recesses 33, 43, and 53. That is, in the first, third, and fourth embodiments, all three recesses 33, 43, and 53 are closed by a single closure member 6. However, when the medical care product has multiple recesses as in the above embodiments, the medical care product may have, for example, multiple closure members corresponding to the multiple recesses, respectively. That is, the multiple recesses may be closed by different closure members.

[0140] (5n) In the above embodiments, the two mating portions 311, 411 have the same shape and size. However, when multiple mating portions are provided as in the above embodiments, the shapes and sizes of the mating portions may be the same or different. For example, when two mating portions are provided as in the above embodiments, one mating portion may be triangular in top view and the other mating portion may be semicircular in top view. With this configuration, when the medical care product includes a blocking member as in the first, third, and fourth embodiments, each mating portion may be formed to have a shape that matches the corresponding mating portion, making it less likely that the blocking member will be oriented incorrectly relative to the main body member.

[0141] (5o) When the medical care product includes an auxiliary member as in the second embodiment, the shape of the grip portion of the auxiliary member is not particularly limited. For example, the grip portion may be a rod-shaped portion that curves away from the base portion as in the above embodiment, or a column-shaped portion that protrudes from the base portion.

[0142] (5p) In the third and fourth embodiments, the hot / cold agent 8, 8D is configured to be capable of both heat insulation and cold insulation. However, the hot / cold agent may be configured to be capable of at least one of heat insulation and cold insulation. For example, the hot / cold agent may be configured to be capable of only one of heat insulation and cold insulation. For example, a hot / cold agent configured to be capable of heat insulation and a cold agent configured to be capable of cold insulation may be prepared as the hot / cold agent, and these may be used according to the user's preference.

[0143] (5q) When a hot / cold agent is disposed inside the main body member as in the third and fourth embodiments, for example, the material constituting the main body member may be selected according to the temperature of the hot / cold agent. Furthermore, for example, the thickness of the main body member may be designed according to the temperature of the hot / cold agent. This configuration can prevent the main body member from being overheated or overcooled.

[0144] (5r) In the third embodiment, the hot / cold agent 8 is arranged to fill the recesses 33, 43, and 53. However, the hot / cold agent does not necessarily have to be arranged to fill the recesses. In other words, the volume of the hot / cold agent may be smaller than the volume of the space inside the recess, as in the fourth embodiment.

[0145] Even when the volume of the hot / cold agent is smaller than the volume of the space inside the recess, as in the fourth embodiment, there may be a desire to position the hot / cold agent so that it contacts the hot / cold region, as in the third embodiment. In this case, for example, the blocking member may be provided with a support portion configured to support the hot / cold agent. The support portion may be, for example, a portion protruding from the upper surface of the plate-shaped portion. The height of the support portion from the upper surface of the plate-shaped portion is designed, for example, to be a height that allows the support portion to support the hot / cold agent so that it contacts the hot / cold region when the blocking member is attached to the main member. With this configuration, when the blocking member is attached to the main member, the hot / cold agent positioned inside the main member is pushed up toward the inner surface of the recess by the support portion, maintaining contact with the hot / cold region.

[0146] Furthermore, for example, a support portion configured to support a hot / cold agent may be provided inside the recess. The support portion may be, for example, a portion protruding from the inner surface of the recess. The position of the support portion on the inner surface of the recess is set, for example, at a position such that when a hot / cold agent is placed between the support portion and the hot / cold region, no gaps are formed between the hot / cold agent and either the support portion or the hot / cold region. Even with this configuration, when a hot / cold agent is placed between the support portion and the hot / cold region in the recess, the hot / cold agent can be supported by the support portion and maintained in contact with the hot / cold region.

[0147] The above-described configuration is also useful when a commercially available hot / cold agent is used, because commercially available hot / cold agents do not necessarily have a size or shape that corresponds to the space inside the recess.

[0148] In the fourth embodiment, in which the hot / cold agent is disposed with a gap between it and at least a portion of the inner surface of the recess, a hot / cold agent having a smaller volume than the space inside the recess is used. In this case, the shape of the hot / cold agent does not necessarily have to correspond to the shape of the inner surface of the recess. Therefore, from the viewpoint of production costs of medical care products, commercially available hot / cold agents are preferably used.

[0149] (5s) In the third and fourth embodiments, the hot / cold agent 8, 8D is separate from the main body member 2, 2D and the closing member 6. However, the hot / cold agent may be formed integrally with the main body member or the closing member, for example.

[0150] (5t) For example, a hot or cold agent may be applied to a medical care product that includes an auxiliary member as in the second embodiment. For example, the shape and size of the fitting portion of the auxiliary member and the shape and size of the hot or cold agent may be adjusted so that the fitting portion fits into the recess when the hot or cold agent is placed in the recess. For example, the hot or cold agent may be contained within the auxiliary member.

[0151] (5u) In the above embodiment, specific examples of components that can be placed inside the main body member include hot and cold agents, air fresheners, and deodorizers. Other specific examples include a core material that is harder than the main body member. The core material may be made of, for example, resin or metal. The core material may be placed, for example, so as to contact the inner surface of the recess in a range that overlaps the center line L3 in the vertical direction. This configuration can increase the strength of the portion of the main body member that is likely to come into contact with the user.

[0152] Furthermore, for example, the core material may be formed integrally with the main body member rather than being separate from it. That is, the core material may be contained within the main body member. In this case, the core material may be disposed, for example, at a portion of the main body member that includes the center line L3. This configuration also increases the strength of the portion of the main body member that is likely to come into contact with the user.

[0153] (5v) The medical care products 1A, 1C, and 1D of the first, third, and fourth embodiments each include a main body member 2, 2D, and a blocking member 6. The medical care product 1B of the second embodiment includes a main body member 2 and an auxiliary member 7. However, the medical care product may include, for example, only a main body member, or may include all of a main body member, a blocking member, and an auxiliary member.

[0154] (5w) In the above embodiment, the main body members 2, 2D are illustrated as being disposable. However, the main body members may be configured to be reusable, for example. In this case, the main body members may be configured to be sterilizable, for example.

[0155] (5x) In the second embodiment, the medical care product 1B is used by an assistant using the main body member 2 with the auxiliary member 7 attached to assist the pregnant woman in straining. However, the assistant may use only the main body member 2 to assist the pregnant woman in straining. In this case, the assistant uses the main body member 2 by grasping it alone from the bottom portion 31, 41, 51 side, for example.

[0156] (5y) In the above embodiment, the medical care products 1A to 1D are used for strain relief. However, the medical care products can also be used for purposes other than strain relief.

[0157] For example, the medical care product may be used for perineal massage before birth (e.g., in the third trimester), in which case the method of use of the medical care product is generally similar to that for use in straining relief.

[0158] For example, the medical care product can be used to treat lacerations after childbirth. In this case, the medical care product can be used by contacting the laceration site with the medical care product. In this case, it is effective to use a pre-cooled heating / cooling agent to cool the main body member before use.

[0159] For example, the medical care product can also be used to treat menstrual pain. In this case, it is effective to use a preheated hot / cold agent to warm the main body member before use. By contacting the warmed main body member with the abdomen, menstrual pain can be alleviated.

[0160] For example, the medical care product can also be used for hemorrhoid care. In this case, the method of use of the medical care product is generally the same as when used to relieve straining. However, it is possible to adjust the contact position of the medical care product so that pressure is focused on the area around the anus. It is also effective to use the main body member in a warmed or cooled state by using a pre-heated or pre-cooled hot or cold agent. The medical care product can improve blood flow around the anus and alleviate hemorrhoid symptoms.

[0161] Furthermore, for example, the medical care product can also be used to massage areas other than the perineum, which was exemplified above. Areas other than the perineum include, for example, the back, lower back, shoulders, neck, etc. For example, by placing the medical care product on the surface of a bed and having the user lie down on it, the first pressing portion and the second pressing portion can press acupressure points on the back, lower back, etc.

[0162] (5z) The functions of one component in the above embodiments may be distributed among multiple components, or the functions of multiple components may be integrated into one component. Also, part of the configuration of the above embodiments may be omitted. Furthermore, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.

[0163] (5aa) The present disclosure can be realized in various forms, such as the aforementioned main body members 2, 2D, medical care products 1A to 1D that include the main body members 2, 2D as components, and methods of using the medical care products 1A to 1D.
