Description

The present invention relates to a compression underwear or the like for pressurizing a wound after breast surgery, and in particular, adjusting the size of the cushion material accommodated in this compression underwear has the effect of efficiently pressurizing the wound. It relates to a compression underwear that can bring about

Conventionally, after mastectomy, for example, in order to prevent bleeding from the wound, for example, after applying several layers of gauze to the wound, a commercially available bust made of a wide tape material or elastic cloth material is applied. Compression methods such as tightening the chest using a band have been adopted.
However, when the tape material is used, there is a problem that symptoms such as epidermal detachment, blister formation, or dermatitis are likely to occur.
In addition, when a bust band is used, there are problems that it is difficult to adjust the pressure for each patient and that the gauze tends to shift, and it is difficult to uniformly press the wound with the required pressure. As a result, there is a problem that the skin of the wound and the chest wall are uniformly brought into close contact with each other to promote the proliferation of new blood vessels. In addition, there are problems such as an unsightly appearance when worn, and the need for the surgeon to adjust the tightening strength by himself/herself, which is cumbersome.
Therefore, in recent years, techniques related to underwear have been developed to solve the above-described problems, and several ideas have already been disclosed in this regard.

Patent Document 1 discloses a device under the name of "supporter", which relates to a supporter that is used in place of a bandage after surgery for breast cancer or the like.
The device disclosed in Patent Document 1 will be described below. The device disclosed in Patent Document 1 has a front body and a back body made of elastic fiber material, the front body has a pair of left and right cups for covering the breasts, and the shoulders and the center of the front chest of the wearer are joined. It is characterized in that separate joints are provided respectively.
In the device having such characteristics, since both the front body and the back body are made of elastic fiber material, skin peeling or the like does not occur, and the wearer's pain can be reduced. In addition, by providing the joint portion, it is possible to easily adjust the joint between the left and right front body parts and the back body body according to the wearer's size or desired strength. Furthermore, since the cup is provided, by inserting gauze or a pad into the cup, it is possible to prevent the slippage and reduce the trouble of adjusting one's appearance.

In addition, Patent Document 2 discloses a device related to a size-adjustable brassiere under the name of "size-adjustable brassiere."
The device disclosed in Patent Document 2 consists of an inner layer made of sweat-absorbing cotton fabric, a cup-shaped outer layer made of an elastic material, and a cup-shaped air sac inserted between the inner and outer layers. The bag is formed by pasting the peripheral edge of the outer layer and the peripheral edge of the inner layer together, and is equipped with an air inlet and an air release valve for injecting and discharging air, and the outer layer of the air bag has a softer adhesiveness than the inner layer. and
In the device having such characteristics, the size of the air bag can be easily and freely adjusted by injecting and discharging air into and out of the air bag, and the aforementioned peeling of the skin can be prevented. Therefore, the device according to Patent Document 2 can be suitably used even after breast surgery.

According to the idea disclosed in Patent Document 1, when the joint parts are joined together, the front body and the back body made of an elastic fiber material are stretched, thereby generating a restoring force in the direction along the body surface. As a result, the entire chest is tightened by the front body, which is less likely to swell forward, and the back body, which is less likely to swell rearward.
However, since the cup is not made of an elastic fiber material and the restoring force is not as high as that of the front body, the gauze or the like in the cup causes the cup to swell mainly forward. Therefore, it is considered that the effect of pressing the gauze or the like against the wound by the cup is poor. Therefore, in the device disclosed in Patent Document 1, it cannot be said that bringing the joints closer together does not reliably bring about the effect of efficiently pressurizing the wound, and there is a possibility that the recovery of the wound cannot be sufficiently promoted. be.

Next, in the device disclosed in Patent Document 2, the outer layer of the air bag has softer adhesiveness than the inner layer, so the air bag expands mainly toward the outer layer side when filled with air. As a result, the cup-shaped outer layer made of an elastic material expands outward, and the inner layer made of cotton woven fabric becomes difficult to adhere to the wound. Therefore, in the device disclosed in Patent Document 2, it cannot be said that increasing the size of the air sac reliably brings about the effect of efficiently pressurizing the wound. Similarly, it may not be possible to sufficiently promote wound healing.

The present invention has been made in response to such conventional circumstances, and increasing the size of the cushioning material arranged corresponding to the chest wound brings about efficient pressurization to the wound. It is an object of the present invention to provide a compression underwear, a cushioning material and a cover used therein, which can sufficiently promote the recovery of a wound by obtaining a compression underwear.

In order to achieve the above object, the first invention is an undergarment that has a front body and a back body that are made of stretchable cloth material, and that can pressurize the wound of the chest when worn, and the front body is the front body. At least one pocket is arranged so as not to cross the center line of the position where it is divided into left and right, and the pocket is formed by overlapping the outer cloth provided on the front side and the lining cloth provided on the back side of the outer cloth. , the cushion material can be accommodated between the outer cloth and the lining cloth, and the lining cloth has stronger stretchability than the outer cloth.
In the invention having such a configuration, the front body and the back body may be made of one type of stretchable cloth material or multiple types of stretchable cloth materials.

In addition, one pocket is provided only on the right side or only on the left side of the center line of the front body corresponding to whether the wound is formed on the right side or the left side of the chest. A pair is provided for .
Among these, if only one pocket is provided, the part of the front body that is symmetrical about the pocket and the center line is, for example, composed only of the outer cloth that constitutes the pocket, and the outer cloth and The lining cloth that constitutes the pocket may be superimposed, or may be made of a stretchable cloth material different from both the outer cloth and the lining cloth of the pocket.
In addition, when a pair of pockets are provided, the cushioning material is accommodated in at least one of these pockets. As the cushioning material, for example, an airbag, a pad made of cloth, sponge, silicon, or the like, which has elasticity to change its size or has flexibility to change its shape. Those that can be used are used. It should be noted that the cushioning material is desirably planar in order to uniformly apply pressure to the wound.

In the compression underwear having the above configuration, the front body and the back body are made of elastic cloth material, so when the compression underwear is worn on the chest, the front body and the back body are in close contact with the body surface, and the movement of the wearer is not affected. Regardless, the position of the pocket is placed without shifting from the wound. Next, a cushioning material such as an airbag is placed in one pocket or a pair of pockets on the side where the wound is formed, and air is injected into it to increase the size. , the lining fabric of the pocket has greater stretchability than the outer fabric, so the lining fabric expands more than the outer fabric. Also, the lining fabric may have higher flexibility than the outer fabric, and in this case also, the lining fabric expands more than the outer fabric.
That is, the expansion of the cushion effectively increases the pressure applied to the wound as compared to the conventional case.

Next, a second invention is characterized in that in the first invention, the outer fabric of the pocket has longitudinal elasticity.
In the invention having such a configuration, the term "longitudinal stretchability" refers to the property of stretching mainly along the longitudinal direction substantially parallel to the center line of the front body.
In the invention having the above configuration, in addition to the effect of the first invention, for example, when the size of the cushioning material accommodated in the pocket is increased, the outer fabric stretches mainly along the longitudinal direction. A restoring force is generated in the direction that tends to shorten the length of the vertical direction.
Therefore, when the outer cloth is stretched, the cushion material receives pressure mainly in the direction toward the longitudinal center of the outer cloth.

Subsequently, in a third invention, in the first or second invention, the front body has an upper portion arranged above the pocket, and the upper portion is made of at least one laterally stretchable cloth material. characterized by
In the invention having such a configuration, lateral stretchability refers to the property of stretching mainly along the lateral direction substantially orthogonal to the center line of the front body.
In the above-configured invention, in addition to the effects of the first or second invention, the restoring force of the upper portion is generated mainly along the lateral direction in the direction of shortening the length. Therefore, the pocket arranged below the upper portion is prevented from extending in the vertical direction and the pocket itself is prevented from moving upward. In particular, when the third invention has the configuration of the second invention, the restoring force generated in the outer cloth of the pocket when the outer cloth of the pocket is stretched along the longitudinal direction is the restoring force generated in the upper part. and is prevented from weakening.
In the case where only one pocket is provided, the cloth material that constitutes the portion symmetrical to the upper portion with respect to the center line is, for example, made of the same cloth material as the upper portion, or has a different elasticity from that of the upper portion. It may be constructed from a cloth material.

Subsequently, according to a fourth invention, in any one of the first to third inventions, the front body has a front joint portion formed along the center line, and a pair of side joints at the boundary with the back body. It is characterized in that each part is formed.
In the invention having such a configuration, the front joining part can be separated and joined to the left and right of one front body along the center line, and is composed of, for example, a hook-and-loop fastener or a line fastener. Also, the pair of side joints can separate and join the left and right front bodies and the back bodies along their respective boundary parts, and are made of, for example, hook-and-loop fasteners, like the front joints.
In addition to the effect of any one of the first to third inventions, in the invention having the above configuration, the front body can be opened in front and both side portions can be opened and closed, which facilitates wearing and undressing. Also, when wearing compression underwear, the distance between the front body and the back body on both sides is adjusted. Therefore, it is possible to prevent excessive or insufficient tightening force on the body surface.

Furthermore, according to a fifth invention, in any one of the first to fourth inventions, the pockets are provided symmetrically about the center line.
In the invention having such a configuration, when the upper part constituting the third invention is provided, this upper part is also provided symmetrically about the center line. Also, as described above, the cushioning material is accommodated in at least one of the two pockets. Therefore, the invention configured as described above has the same function as any one of the first to fourth inventions.

Furthermore, a sixth invention is a cushioning material used in the compression underwear according to any one of the first to fifth inventions, which has a first surface and a second surface, and has a gas inside thereof. is provided at the boundary between the first surface and the second surface, and the bag body is capable of adjusting the internal volume.
In the invention having such a configuration, the inlet and outlet are provided at the boundary between the first surface and the second surface, and the first surface side and the second surface side are symmetrical about the surface including this boundary. Since the inlet/outlet is present at the position where it is located, regardless of whether the cushion material is stored in the left or right pocket of the compression underwear, it acts as a common cushion material that ensures ventilation of the inlet/outlet. .

Next, a seventh invention is provided with the cushioning material according to the sixth invention, and the outer cloth is provided with through-holes at locations corresponding to the inlet and outlet ports when the cushioning material is accommodated in the pocket. Characterized by
In the invention having such a configuration, since the through-holes are provided at locations corresponding to the inlets and outlets, it is not necessary to take out the cushioning material when pouring gas into the cushioning material.
Further, when the cushioning material is used for the compression underwear according to the fifth invention, through holes are also provided in the outer fabrics of the pair of pockets. In this case, if the through-holes are arranged symmetrically about the center line, by reversing the front and back of the cushioning material when stored in one pocket, the through-holes can easily be inserted into the other pocket as well. are placed in line with the

An eighth invention is a covering that is housed in a pocket while covering at least one of the first and second surfaces constituting the cushioning material according to the sixth invention, wherein the covering is , one or more third surfaces having lower stretchability than the first surface member constituting the first surface and having lower stretchability than the second surface member constituting the second surface At least one of the third surface members is arranged between the outer cloth of the pocket and the cushioning material.
In the invention having such a configuration, the cover including one or more third surface members includes (1) a configuration in which two third surface members are superimposed to form a bag shape, and (2) A structure in which one third surface member and one other surface member are superimposed to form a bag-like structure, or (3) a structure consisting of only one third surface member can be considered.

Of these, in the configuration (1), the cushioning material is accommodated in the pocket while the cushioning material is accommodated inside the cover. Therefore, both the first surface and the second surface are covered by the third surface member.
In addition, in the configuration of (2), similarly to the configuration of (1), the cushion material is accommodated in the pocket while being accommodated inside the cover. Therefore, the third surface member covers either the first surface or the second surface. In this case, in order to make the cushioning material stored inside the cover usable in both of the pair of pockets, the cushioning material should be placed in the cover with the left and right orientations reversed.
Furthermore, in the configuration of (3), the cover and the cushioning material are accommodated in the pocket in a state of being overlapped. Therefore, the third surface member covers either the first surface or the second surface.

In the invention having such a configuration, in any of the above configurations (1) to (3), the third surface member is arranged between the outer cloth of the pocket and the cushion material, and the third surface member is Since it has lower stretchability than both the first and second plane members, the third plane member allows at least the surface of the pocket of the first and second planes of the cushioning material to be stretched. The expansion of the one located on the fabric side is suppressed.
Therefore, when the cover is used, the thickness of the inflated cushioning material is evenly reduced compared to when the cover is not used, so that the volume of the cushioning material is substantially reduced.

According to the first aspect of the invention, the position of the pocket is arranged without deviating from the wound regardless of the movement of the wearer.
In addition, the expansion and contraction of the cushion material effectively increases the pressure applied to the wound compared with the conventional case, so that recovery of the wound can be sufficiently promoted especially immediately after surgery.

According to the second invention, in addition to the effect of the first invention, since the outer fabric has longitudinal elasticity, the cushioning material receives pressure mainly in the direction toward the center of the longitudinal direction of the outer fabric. In addition, it is possible to prevent the thickness of the cushion material from increasing in the portions near the upper edge and in the portion near the lower edge and from becoming insufficient in the central portion. In addition, since the cushioning material is pressed against the chest when worn, the thickness of the cushioning material is substantially uniform, and the wound can be uniformly pressurized.
Furthermore, since it is possible to prevent the thickness of the central portion from becoming insufficient, the silhouette when worn is comparable to that of the unaffected side.

According to the third invention, in addition to the effects of the first or second invention, the expansion of the pocket along the longitudinal direction and the movement of the pocket itself are suppressed, so that the pocket does not expand excessively upward. , can be prevented from slipping from the wound. In particular, when the third invention includes the upper part of the second invention, the restoring force generated in the outer fabric of the pocket is prevented from being weakened by offsetting the restoring force generated in the upper part. , the wound can be more uniformly pressurized. Therefore, the entire wound can be recovered more quickly.

According to the fourth invention, in addition to the effects of any one of the first to third inventions, it is easy to put on and take off the compression underwear, so that it can be worn by an unconscious patient immediately after surgery, and can be worn on the body. It can reduce the burden when a patient who has difficulty moving the body puts it on by himself/herself.

According to the fifth invention, in addition to the effect of any one of the first to fourth inventions, since the pockets are provided symmetrically about the center line, the patient who has the wound on the right side and the patient who has the wound on the left side Compression underwear having a common configuration can be applied to both. Therefore, since the manufacturing cost can be suppressed, the cost burden on the wearer can be reduced.

According to the sixth invention, regardless of whether the cushion material is housed in the left or right pocket, ventilation of the inlet/outlet is ensured, so there is no need to manufacture cushion materials having different shapes for the left and right pockets. . Also, when the wearer attaches the cushioning material to the pocket, it is not necessary to pay attention to the front and back of the cushioning material, which is convenient.

According to the seventh invention, in addition to the effects of the first to fifth inventions, gas can be injected and discharged without taking out the cushioning material, so the size of the cushioning material can be quickly adjusted.
In addition, when the compression underwear has a pair of pockets and the through holes are arranged symmetrically about the center line, by reversing the front and back of the cushioning material when it is stored in one pocket, Also, the pouring/discharging port can be aligned with the through hole without difficulty.

According to the eighth invention, the volume of the cushion material is substantially reduced by the third surface member. Therefore, the use of the cover can increase the pressure applied to the wound with a small amount of air compared to when the cover is not used. Therefore, it becomes possible to adjust the pressure quickly.

As shown in FIGS. 1( a ) and 1 ( b ), the compression underwear 1 according to Example 1 includes a front body 2 and a back body 3 having stretchable cloth material, and when worn, the wound on the chest, for example, Bra-type underwear that can be used to pressurize wounds after mastectomy or breast-conserving surgery.
The front body 2 includes a pair of pockets 4, 4 arranged symmetrically about a center line CL at a position that divides the front body 2 into left and right substantially equally, and an upper portion arranged above the pockets 4, 4. 5,5 and underbelt portions 6,6 arranged below the pockets 4,4.

Further, the boundaries between the pockets 4, 4 and the upper portions 5, 5 are separated by sewn portions 7, 7 provided substantially perpendicular to the center line CL so as not to communicate with each other. Boundaries between the pockets 4, 4 and the underbelt portions 6, 6 are also separated by sewn portions 8, 8 provided substantially perpendicular to the center line CL so as not to communicate with each other. Therefore, the pockets 4, 4 each have a substantially pentagonal shape in plan view.
In addition, the left-right direction of the front body 2 is a direction substantially perpendicular to the midline of the wearer when worn. The center line CL is an imaginary line that is considered to be at a position that substantially equally divides the front body 2 and the back body 3 in the horizontal direction.

Further, the front body 2 is formed with a front joint portion 9 along the center line CL so that the front can be opened. Specifically, the front joint portion 9 is composed of a wire fastener 9a and a strip-shaped piece of cloth 9b to which the wire fastener 9a is sewn. However, instead of the line fastener 9a, a hook-and-loop fastener or a point fastener may be used. The upper end of the piece of cloth 9b is folded outward in a substantially triangular shape to form a cover portion 9c for covering the slider and pull of the line fastener 9a.

Next, the back body 3 includes a central portion 10 connected to the upper portions 5, 5 and an underbelt portion 11 arranged below the central portion 10 and arranged between the underbelt portions 6,6. Boundaries between the upper parts 5, 5 and the central part 10 are separated by stitched parts 12, 12 so as not to communicate with each other. Similarly, the boundary between the central portion 10 and the underbelt portion 11 is also partitioned by the sewn portion 13 so that they cannot communicate with each other.
Further, both the neck and side trimmings of the compression underwear 1 are reinforced by sewing belt-like cloth rubbers 14 thereon.

Next, as shown in FIGS. 2 and 3, a pair of lateral joints 15, 15 are formed at the two boundaries between the front body 2 and the back body 3, respectively. Specifically, the side joints 15 are constructed by sewing hook-and-loop fasteners 16a and 16b along the edge 2a of the front body 2 and the edge 3a of the back body 3, respectively.
Of these, the hook-and-loop fastener 16a sewn to the front body 2 is wider in the left-right direction than the hook-and-loop fastener 16b sewn to the back body 3, so that the hook-and-loop fastener 16b is engaged with the hook-and-loop fastener 16a. By changing the wearing position, the size of the compression underwear 1 around the waist can be adjusted. In addition to this, the side joints 15, 15 may be configured by a line fastener or a point fastener.

As shown in FIGS. 3(a) and 3(b), in the front body 2, the pocket 4 has a surface cloth 17 provided on the front side and a lining cloth 18 provided on the back side of the surface cloth 17. A planar cushioning material 28 (see FIG. 5) can be accommodated between the outer cloth 17 and the lining cloth 18. As shown in FIG.
More specifically, the front cloth 17 is formed by sewing two front cloth pieces 17a and 17b, which are three-dimensionally cut elastic cloth materials made of synthetic fibers, with a sewn portion 17c that is slightly inclined with respect to the center line CL. It is formed. For the outer fabric 17, for example, when a load of 14.7 (N) is applied, the fabric has a longitudinal elongation rate of 190±20 (%) and a lateral elongation rate of 90±20 (%) ("JIS L 1096 Textile Test Methods for Woven and Knitted Fabrics") is selected. However, other elongation rates may be selected. Further, the outer cloth 17 is provided with a through hole 17d at a position through which the pouring/discharging port 30 can be inserted when the cushion material 28 is accommodated in one of the pockets 4 and 4. As shown in FIG.
Similarly, the lining cloth 18 is formed by stitching two lining cloth pieces 18a and 18b, which are three-dimensionally cut synthetic fiber elastic cloth materials, by a stitching portion 18c arranged at the same position as the stitching portion 17c. It was formed by However, the lining cloth 18 has stronger stretchability than the outer cloth 17 . That is, when a downward load of the same strength is applied to the outer cloth 17 and the lining cloth 18 of the same size for a certain period of time, the stretched length of the lining cloth 18 is longer than that of the outer cloth 17 . For example, the longitudinal and transverse elongation rates of the fabric of the lining cloth 18 are selected to be 10 to 30 (%) greater than the respective elongation rates of the outer fabric 17, but other elongation rates are selected. May be selected.

Subsequently, the upper part 5 is formed by overlapping a front cloth 19 and a back cloth 20 both made of stretchable synthetic fiber material. Among them, the outer cloth 19 is made of the same kind of cloth material as the outer cloth 17 of the pocket 4 and has the same stretchability as the outer cloth 17 . Also, the lining cloth 20 of the upper part 5 has lower stretchability than the lining cloth 18 of the pocket 4 , but has higher stretchability than the outer cloth 17 of the pocket 4 .
However, the stretching directions of the outer cloth 19 and the lining cloth 20 of the upper part 5 are both different from the stretching direction of the outer cloth 17 of the pocket 4 . This point will be described in detail with reference to FIG.

The underbelt portion 6 is formed by sewing a belt-like cloth rubber 22 to a front cloth 21 made of the same cloth material as the front cloth 17 of the pocket 4 . Specifically, the outer cloth 21 and the outer cloth 17 are made of the same cloth material. In addition, the cloth rubber 22 has lateral stretchability that expands and contracts mainly along the lateral direction substantially orthogonal to the center line CL of the front body 2 when worn, and the contractile force of the cloth rubber 22 is the cloth material constituting the compression underwear 1. is the largest of

Next, in the back body 3, the central portion 10 is formed by overlapping a front cloth 23 provided on the front side and a lining cloth 24 provided on the back side of the front cloth 23. As shown in FIG. Out of these, the outer cloth 23 is made of the same kind of cloth material as the outer cloth 17 of the front body 2, and the three outer cloth pieces 23a, 23b, and 23b obtained by three-dimensional cutting of this cloth material are arranged with respect to the center line CL. It is formed by stitching with slightly inclined stitching portions 23c, 23c.
The lining cloth 24 is made of the same kind of cloth material as the lining cloth 20 of the upper part 5 . Therefore, even in the central portion 10 , the lining cloth 24 has higher stretchability than the outer cloth 23 .

The underbelt portion 11 is formed by sewing a cloth rubber 26 made of the same cloth material as the cloth rubber 22 of the front body 2 to a front cloth 25 made of the same cloth material as the outer cloth 23 . Of these, the cloth rubber 26 is made of the same material as the cloth rubber 22 and has lateral elasticity. Therefore, the strength of contractile force of the cloth rubber 26 is also the largest among the cloth materials constituting the compression underwear 1 .

Next, the configuration of the pockets that constitute the compression underwear will be described in more detail with reference to FIG. FIG. 4(a) is a plan view of the pocket constituting the compression underwear according to Example 1 when viewed from the outer cloth side, and FIG. 4(b) is a view of the pocket when viewed from the lining cloth side. is a plan view of the. 1 to 3 are denoted by the same reference numerals in FIG. 4, and description thereof will be omitted.
As shown in FIG. 4( a ), on the one side of the front body 2 having the cloth piece 9 b , the outer cloth pieces 17 a and 17 b of the pocket 4 both have longitudinal elasticity indicated by arrow A ₁ . there is Here, the term "longitudinal stretchability" refers to the property of stretching mainly along the longitudinal direction Y substantially parallel to the center line CL of the front body 2 . Specifically, among the elongation rates of the outer cloth 17, the elongation rate in the longitudinal direction is the elongation rate in the Y direction.
Since the outer cloth pieces 17a and 17b of the pocket 4 and the outer cloth 21 of the underbelt portion 6 are made of the same single cloth material, the outer cloth 21 also has longitudinal elasticity. On the other hand, the outer fabric 19 of the upper portion 5 has lateral elasticity indicated by arrow _A2 .

Next, as shown in FIG. 4(b), the lining pieces 18a and 18b of the pocket 4 have elasticity, but this is not along a specific direction. On the other hand, the lining cloth 20 of the upper portion 5 and the cloth rubber 22 of the underbelt portion 6 each have lateral elasticity indicated by arrow _A2 .
Further, in the lining cloth pieces 18a and 18b, a receiving opening 27 is provided at a position where the stitched portion 18c and the stitched portion 13 intersect, for storing and taking out the cushioning material 28 from the pocket 4. As shown in FIG. The other part of the front body 2 that does not have the piece of cloth 9b has the same structure as above.

Next, the cushion material accommodated in the pocket constituting the compression underwear according to Example 1 will be described with reference to FIG. 5 . Fig. 5(a) is a plan view of a cushioning material accommodated in a pocket constituting the compression underwear according to Example 1, and Fig. 5(b) is a front view of the compression underwear containing the same cushioning material in a pocket. is. 1 to 4 are denoted by the same reference numerals in FIG. 5 as well, and description thereof will be omitted.
As shown in FIG. 5(a), the cushioning material 28 accommodated in at least one of the pockets 4, 4 of the front body 2 has a gas inlet and outlet 30 through which gas is injected and discharged. is a bag whose volume can be adjusted.

The cushion material 28 has a first surface 28a which is substantially rectangular in plan view and a second surface 28b which has the same shape as the first surface 28a. Specifically, the cushion material 28 is formed by bonding together the peripheral edge portion of the first surface member 29a forming the first surface 28a and the peripheral edge portion of the second surface member 29b forming the second surface 28b. A chamfered portion 28c is formed by chamfering one corner of the substantially rectangular shape. The chamfered portion 28c is intended to be arranged near the armpit of the wearer when the cushion material 28 is accommodated in the pockets 4,4. Both the first surface member 29a and the second surface member 29b are made of a stretchable cloth material. The first plane member 29a and the second plane member 29b may have longitudinal elasticity.

Furthermore, the cushion material 28 is provided with an inlet/outlet port 30 at the boundary between the first surface 28a and the second surface 28b at one corner 28d.
Specifically, the pouring/discharging port 30 is made of a synthetic resin that is flexible and bendable, has an opening/closing cover at one end, and has a length of about 2 cm and a diameter of about 1 cm. It consists of a covered tube 30a and a check valve 30b which is provided integrally with the other end of this covered tube 30a and accommodated inside the cushion material . More precisely, most of the capped tube 30a near the tip protrudes through the boundary between the first surface 28a and the second surface 28b, and the check valve 30b protrudes from the first surface inside the cushion material 28. It is adhesively fixed to the member 29a.
Therefore, as shown in FIG. 5(b), the outer cloths 17, 17 penetrate into the places where the lidded tube 30a of the inlet/outlet 30 can be inserted when the cushion material 28 is accommodated in the pockets 4, 4. Holes 17d, 17d are provided. Therefore, the wearer can supply air to the cushioning material 28 by exposing most of the tube 30a near the tip from the through hole 17d and connecting an air pump to the opening.

Also, the through holes 17d, 17d are provided close to each other with the center line CL interposed therebetween. This makes it possible to dispose the lidded tube 30a closer to the front joint portion 9 regardless of whether the cushion material 28 is stored in the pocket 4 or 4. As shown in FIG. Therefore, depending on the arrangement of the inlet/outlet port 30 in the cushioning material 28, the through holes 17d, 17d are provided within the range of the pockets 4, 4 and are spaced apart from each other toward the side joint portions 15, 15 across the center line CL. It's okay to be
Since the inlet/outlet port 30 of the cushion material 28 is provided at the boundary between the first surface 28a and the second surface 28b, if the first surface member 29a and the second surface member 29b have substantially the same shape, this Since the pouring/discharging port 30 can be positioned symmetrically on the first surface 28a side and the second surface 28b side with respect to the plane including the boundary, the cushioning material 28 can be placed on either the left or right side of the compression underwear 1. Regardless of whether it is stored in the pocket 4, it becomes a common cushioning material that ensures the ventilation of the inlet/outlet port 30. - 特許庁Therefore, there is no need to manufacture the cushion material 28 with different shapes for the left and right pockets 4, 4, and when the wearer attaches the cushion material 28 to the pockets 4, 4, there is no need to pay attention to the front and back sides of the cushion material 28. Easy to use.

Next, the action of the pocket will be described in more detail with reference to FIG. 6(a) and 6(b) are cross-sectional views taken along line AA in FIG. 5, respectively. 1 to 5 are denoted by the same reference numerals in FIG. 6, and descriptions thereof are omitted.
As shown in FIG. 6(a), before putting on the compression underwear 1, air is supplied to the cushion material 28 housed in the pocket 4 through the inlet/outlet 30 (see FIG. 7), and the size of the air is adjusted. When increased, the outer cloth 17 and the lining cloth 18 of the pocket 4 are stretched and expanded. However, since the lining cloth 18 has stronger elasticity than the front cloth 17 , the lining cloth 18 expands more than the front cloth 17 .
Therefore, in the compression underwear 1, the expansion of the cushioning material 28 is as compared with the case where the stretchability of the outer cloth and the lining cloth are equal, or the conventional case where the outer cloth has stronger stretchability than the lining cloth. Effectively increases the pressure applied to the wound.

On the other hand, when the wearer feels that the pressure applied to the wound is excessive, the air is exhausted through the inlet/outlet 30 and the size of the cushioning material 28 is reduced, so that the lining cloth 18 is larger than the outer cloth 17. Also, the shape of the backing fabric 18 is likely to change, so that mainly the backing fabric 18 is recessed toward the cushion material 28 side. That is, the contraction of the cushioning material 28 effectively reduces the pressure applied to the wound as compared with the conventional case.

In addition, since the outer cloth 17 is mainly stretched along the longitudinal direction Y, restoring forces F, F are generated in directions that tend to shorten the length of the outer cloth 17 in the longitudinal direction Y. FIG. Since the restoring forces F, F act as pressures applied to the cushioning material 28, the cushioning material 28 receives the pressure in directions that are not dispersed in directions separating from each other along the longitudinal direction Y. As shown in FIG. Therefore, the thickness of the central portion of the cushion material 28 in the vertical direction is increased.

Therefore, as shown in FIG. 6(b), when the size of the cushion material 28 increases, mainly the lining 18 expands and presses the chest 50, even when worn. In addition, due to the restoring forces F, F of the outer cloth 17, the thickness of the cushion material 28 itself increases in the central portion in the longitudinal direction, so the thickness of the cushion material 28 near the sewn portion 7 and near the sewn portion 13 increases. Thinning is prevented. However, the thickened central portion of the cushion material 28 is pushed by the chest 50, and the central portion is gently recessed.
As a result, the cushioning material 28 has almost the same thickness as a whole when worn, so that the wound (not shown) is pressed with a uniform force.
In addition to the outer cloth 17, the lining cloth 18 may also have longitudinal elasticity. In this case, the wound is more evenly pressed.

In addition, since the outer cloth 19 of the upper portion 5 has lateral stretchability (see FIG. 4A), when the outer cloth 17 of the pocket 4 is stretched along the longitudinal direction Y, the outer cloth The restoring force of 19 is generated mainly along the lateral direction in the direction of shortening the length of the outer cloth 19 . Therefore, the restoring force F generated in the outer cloth 17 of the pocket 4 is prevented from being weakened by offsetting the restoring force generated in the outer cloth 19 of the upper portion 5 . Since the lining cloth 20 of the upper part 5 also has lateral stretchability (see FIG. 4(b)), the lining cloth 20 also exerts the above effect.

In the compression underwear 1 configured as described above, since the front body 2 and the back body 3 are made of stretchable cloth material, when the compression underwear 1 is worn on the chest, the front body 2 and the back body 3 are in close contact with the body surface. . In particular, since the underbelt portions 6, 6 and the underbelt portion 11 have the strongest lateral elasticity, the compression underwear 1 is prevented from slipping off the chest due to the movement of the wearer. Therefore, the pockets 4, 4 are arranged without being displaced from the wound, and the wound is continuously pressurized when the cushion material 28 is accommodated.

Further, since the compression underwear 1 is provided with the front joint portion 9 and the side joint portions 15, 15, it is easy to put on and take off. When the compression underwear 1 is worn, the intervals between the hook-and-loop fasteners 16a and 16b on both sides are adjusted, so that the tightening force on the body surface is prevented from becoming excessive or insufficient. Furthermore, since the side joints 15, 15 are composed of the hook-and-loop fasteners 16a, 16b having flexibility, pain is not felt in both sides when sleeping.

In addition, in the compression underwear 1, the inlet/outlet port 30 of the cushion material 28 is provided at the corner 28d of the boundary between the first surface 28a and the second surface 28b, and the cover forming the inlet/outlet port 30 is provided. Since the tube 30a has a bendable length, the lidded tube 30a can be easily inserted through the through holes 17d, 17d.
Further, since the through holes 17d, 17d are arranged symmetrically about the center line CL, by reversing the front and back sides of the cushioning material 28 from when it is accommodated in one pocket 4, the other pocket 4 can be provided with the above-described configuration. Similarly, the lidded tube 30a is naturally aligned with the other through hole 17d.

As described above, according to the compression underwear 1 according to the embodiment, the pockets 4, 4 are arranged without being displaced from the wound regardless of the movement of the front wearer. In addition, the cushioning material can maintain the state of pressurizing the wound.
In addition, since the lining cloth 18 has higher stretchability than the outer cloth 17, the expansion and contraction of the cushioning material effectively increase or decrease the pressure applied to the wound as compared with the conventional case. can do. Therefore, especially immediately after surgery, the skin of the wound and the chest wall can be uniformly adhered to sufficiently promote the growth of new blood vessels, and an appropriate amount of pressure can be easily realized according to the passage of time after surgery. It is possible. In addition, since such pressure adjustment can be performed by the wearer himself/herself or a nurse, the burden on the surgeon can be reduced.

In addition, according to the pressurized underwear 1, the cushioning material 28 has almost the same thickness as a whole when worn due to the restoring forces F, F of the outer cloth 17, so that it is possible to prevent the central portion from becoming insufficient in thickness. , it is possible to pressurize the wound uniformly. Therefore, the entire wound can be recovered more quickly. At the same time, since the silhouette when worn is comparable to that of the healthy side, it is possible to solve the conventional problem of poor appearance when worn.
Furthermore, since the surface cloth 19 of the upper portion 5 has lateral stretchability, the restoring force F generated in the surface cloth 17 of the pocket 4 cancels out the restoring force generated in the surface cloth 19 and weakens. Since this is prevented, the wound can be more uniformly pressurized.

In addition, since the compression underwear 1 is provided with the front joint 9 and the side joints 15, 15, it is easy to put on and take off. It can reduce the burden when a patient who has difficulty in moving the body puts it on by himself/herself.
When the compression underwear 1 is worn, the tightening force on the body surface is prevented from becoming excessive or insufficient, so that the wound can be fully recovered not only immediately after surgery but also when worn for a certain period thereafter. In addition, discomfort such as suffocation due to excessive tightening can be reduced.
Furthermore, since the through holes 17d, 17d are provided close to each other with the center line CL interposed therebetween, the wearer can easily supply and exhaust air to and from the cushion material . In addition, since the lidded tube 30a is easily inserted through the through-holes 17d, 17d, the air pump can be easily connected to the through-holes 17d, 17d. There is no need to manufacture a cushioning material with different arrangement of the inlet/outlet ports 30 for each. Therefore, since the manufacturing cost can be suppressed, the cost burden on the wearer can be reduced.

A cover accommodated in a pocket of a compression underwear according to a second embodiment of the present invention will be described with reference to FIG. FIG. 7(a) is a plan view of a cover according to Example 2, and FIG. 7(b) is a plan view of the cover accommodating a cushion material therein. 1 to 6 are denoted by the same reference numerals in FIG. 7, and description thereof will be omitted.
As shown in FIG. 7A, the cover 31 according to the second embodiment includes two substantially rectangular third surface members 31a and 31b. Both of the third plane members 31a and 31b are made of the same cloth material having lower stretchability than the first plane member 29a and lower stretchability than the second plane member 29b. . That is, when a downward load of the same strength is applied to the third plane members 31a, 31b and the first plane member 29a of the same size for a certain period of time, the extended length is equal to that of the third plane member 31a. , 31b. The same applies to the relationship with the second surface member 29b.

Specifically, the cover 31 is closed on three of its four sides and has an opening 32 on the remaining one side, and is formed in a bag-like shape into which the cushion material 28 can be inserted. . At the opening 32, hook-and-loop fasteners 32a and 32b are sewn to the third plane members 31a and 31b, respectively. Therefore, when the third surface member 31a is folded toward the third surface member 31b, the hook-and-loop fasteners 32a and 32b are engaged with each other to seal the opening 32. As shown in FIG.
One of the closed corners of the cover 31 is notched to form a notch 33 through which the lidded tube 30a of the cushion material 28 can be inserted.

Next, as shown in FIG. 7(b), these are accommodated in the pockets 4, 4 with the cushion material 28 accommodated inside the cover 31. Next, as shown in FIG. Therefore, both the first surface 28a and the second surface 28b of the cushion material 28 are covered by the third surface members 31a and 31b. At this time, in the right front body 2, for example, when the third surface member 31a is arranged between the outer cloth 17 of the pocket 4 and the cushion material 28, in the left front body 2, the third A surface member 31b is arranged between the outer cloth 17 of the pocket 4 and the cushion material 28. As shown in FIG.

In the cover 31 having the above configuration, the third surface members 31a and 31b have lower stretchability than both the first surface member 29a and the second surface member 29b. The expansion of the first surface 28a and the second surface 28b of the cushion material 28 is suppressed by the members 31a and 31b.
Therefore, when the cover 31 is used, the thickness of the cushion material 28 into which the air is injected is evenly reduced compared to when the cover 31 is not used, so the volume of the cushion material 28 is substantially reduced.

Therefore, the use of the cover 31 can increase the pressure applied to the wound with a small amount of air compared to when the cover 31 is not used. Therefore, it becomes possible to quickly adjust the pressure, and the operability is improved. Further, by selecting whether or not to use the cover 31 and the strength of elasticity of the third surface members 31a and 31b, it is possible to finely adjust the pressure on the wound.

In addition, the compression underwear which concerns on this invention is not limited to what is shown in an Example. For example, the compression underwear 1 may be a brassiere type or a shirt type having sleeves. In the former case, the seams 7, 7 are moved toward the upper portions 5, 5 to expand the pockets 4, 4 in the longitudinal direction, and the cushioning material 28 is made to substantially conform to the shape of the pockets 4, 4. , You may comprise a wearer's armpit so that pressurization is possible.
In the latter case, the sewn portions 7, 7 may be moved toward the sleeve portion to expand the upper portions of the pockets 4, 4 in the lateral direction so that the wearer's armpits can be pressurized.
Furthermore, instead of the front joint portion 9 and the side joint portions 15, 15, a cloth material having lateral elasticity may be used, and instead of the sewn portions 12, 12, a joint portion that can be joined and separated may be provided. can be
The compression underwear 1 may be provided with one pocket 4 only on the right side or only on the left side of the center line CL.

In addition, the lining 18 of the pocket 4 may have longitudinal elasticity. Further, the outer fabric 19 and the lining fabric 20 of the upper portion 5 do not necessarily have lateral stretchability. Furthermore, the backing cloth 20 may be omitted.
The cushion material 28 may be a cloth, sponge, or silicon pad other than an airbag. In this case, the pressure applied to the wound can be adjusted by changing the number and thickness of the cushioning materials accommodated in the pockets 4,4. Therefore, the through holes 17d, 17d can be omitted. Also, the compression underwear 1 may be provided with the cushion material 28 in a removable or non-removable manner.
In addition, the stretchability of the third surface members 31a and 31b may not be the same.

The present invention is a compression underwear that can be worn by a patient who has undergone mastectomy or breast-conserving surgery, or who has a wound on the chest to uniformly compress the wound with the necessary pressure, and a cushion used therefor. It can be used as a material and a covering.
