Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an underwear for reducing swelling in the perineal area. Background Technology
[0002] Postoperative edema of the perineum and genital area is a common clinical symptom. During childbirth, prolonged labor and continuous pressure from the fetal head can easily lead to impaired blood circulation in the perineum, causing edema. In men, postoperative edema of the testicles and perineum is common due to surgical trauma and local pressure. This type of edema not only delays wound healing and increases the risk of incision infection, but also causes severe pain, negatively impacting the postoperative recovery process.
[0003] Meanwhile, postoperative patients often experience vaginal discharge, and women may also experience lochia discharge after childbirth. Currently, sanitary pads and diapers are commonly used in clinical practice to absorb these discharges. However, these traditional products can only absorb discharge and cannot effectively relieve or treat edema in the perineal and genital areas, making it difficult to solve the many problems caused by edema. Therefore, there is an urgent need for a solution that can both absorb discharge and reduce local swelling. Utility Model Content

Detailed Implementation
[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0026] The purpose of this invention is to provide underwear for reducing swelling in the perineal area, thereby overcoming the shortcomings of traditional medicated compress methods described in the background section. This underwear combines the functions of absorbing secretions and reducing swelling, enabling precise drug delivery to different areas of the perineal edema, and improving ease of use and comfort.
[0027] like Figure 1 , Figure 2 As shown, the underwear body 1 adopts the style of conventional underwear, including a front piece 11, a back piece 12, and a crotch area connecting the two. The front piece 11 and the back piece 12 are sewn together on both sides to form leg openings and a waist opening. The improvement of this utility model is that a partition 13 is provided in the crotch area of the underwear body 1. Specifically, the partition 13 is located on the inner side of the front piece 11 (the side closest to the body), and its periphery is connected to the corresponding position of the front piece 11, thereby forming a storage space 14 for placing the dressing 2 between the front piece 11 and the partition 13 (see...). Figure 1 The shape of the partition 13 roughly matches the perineal coverage area, and its size is slightly smaller than the front piece 11 to ensure that there is enough space to accommodate the dressing 2 without affecting the wearing of the underwear.
[0028] The dressing 2 is placed within the aforementioned storage space 14 to hold the rhubarb and Glauber's salt powder and apply it close to the perineal skin to exert its medicinal effect. The dressing 2 is preferably made of a soft, breathable fabric, such as cotton or non-woven fabric, to ensure that the medicine can penetrate the dressing and act on the skin while avoiding skin irritation. The shape of the dressing 2 is designed to match the crotch shape of the front piece 11, so that when the dressing 2 is placed, it can fit closely to the contour of the perineum, increasing the contact area of the medicine and the therapeutic effect. This invention organically combines traditional Chinese medicine external application therapy with perineal care underwear, which not only effectively relieves swelling and pain in the perineum after childbirth or surgery, but also greatly facilitates daily use and care for patients.
[0029] To ensure the dressing 2 is secured in the correct position, this invention incorporates a detachable connection structure between the partition 13 and the dressing 2. For example... Figure 3 As shown, several connecting pieces 131 are sewn onto the side of the partition 13 facing the dressing 2, each connecting piece 131 having a connecting hole; correspondingly, buttons 26 are sewn onto the dressing 2 at the corresponding positions. In use, the dressing 2 is placed into the storage space 14, the buttons 26 on the dressing 2 are aligned with the connecting holes on the partition 13 and passed through, and then the buttons are fastened to securely fix the dressing 2 to the partition 13. In this way, the dressing 2 is stably fixed in the corresponding position of the perineum, and the dressing 2 will not slide or shift during user activity. When it is necessary to change the dressing 2 or wash the underwear, simply unfasten the buttons 26 to remove the dressing 2, which is very convenient. Besides buttons, those skilled in the art can also use other equivalent connection methods, such as female snap buttons on the partition 13, male snap buttons on the dressing 2, or Velcro strips, magnetic snaps, etc., as long as reliable connection and convenient separation of the dressing 2 and the partition 13 can be achieved.
[0030] like Figure 4 As shown, the upper end of the dressing 2 (corresponding to the position of the front waistband of the underwear) has multiple openings 21. In this embodiment, there are three openings 21, located on the left, middle, and right sides of the upper end of the dressing 2. These openings 21 are the entrances for filling the dressing 2 with medicine or adding medicinal powder. Each opening 21 is equipped with a sealing structure, which in this embodiment uses Velcro 211: that is, the male and female sides of Velcro are sewn onto the two edges of the opening 21, and the opening 21 can be closed and sealed by pressing. The Velcro 211 ensures that the opening 21 can be tightly closed when no medicine is needed, preventing the medicinal powder from leaking out. When it is necessary to add rhubarb and Glauber's salt powder into the dressing 2, simply pull open the Velcro 211 to open the opening 21, pour in the medicinal powder, and then close the Velcro. The operation is very simple.
[0031] The interior of the dressing 2 is divided into multiple independent drug-filling areas 22. The number and position of these drug-filling areas 22 correspond one-to-one with the openings 21, and in this embodiment, they are also divided into three areas: left, middle, and right (see...). Figure 4The preferred method for dividing the drug-filling areas 22 is to sew a grid-like stitching thread 23 inside the dressing 2. Specifically, a sewing machine is used to sew several crisscrossing stitches on the fabric of the dressing 2, dividing the interior of the dressing 2 into several small grid-like compartments, each of which constitutes a drug-filling area 22. Through the division by the grid stitching thread 23, the rhubarb and Glauber's salt powder inside the dressing 2 is confined to its respective area, preventing it from freely flowing to other areas or settling at the bottom of the dressing. This ensures that the amount of powder in each drug-filling area 22 is relatively uniform and covers the corresponding anatomical parts of the perineum. When the swelling in a certain area is more severe, the amount of powder can be increased separately through the opening 21 corresponding to that area, making the powder thickness and drug concentration in that area higher than in other areas, achieving targeted and enhanced treatment. For areas with less noticeable swelling, less powder or no powder can be added to avoid drug waste and unnecessary irritation to normal tissues.
[0032] To further improve the adaptability of the dressing 2 to perineal swelling, each drug-filling area 22 is also equipped with cross-distributed elastic ribs 24 (see Figure 4 The elastic band 24 can be made of elastic fiber material and is crisscrossed and sewn onto the inner surface of the drug-filling area 22 along a diagonal direction. In this embodiment, the elastic band 24 is placed between a breathable non-woven fabric layer 25 on the inner side of the dressing 2 and the inner surface of the dressing. That is, a breathable non-woven fabric 25 is first laid on the inner surface of the dressing 2 (the side close to the drug), then the elastic band 24 is sewn onto the non-woven fabric 25, and then the non-woven fabric 25 is sewn and fixed to the main body fabric of the dressing 2. In this way, the elastic band 24 is clamped and fixed between the non-woven fabric 25 and the main body of the dressing, so that it will not directly contact the skin and will not affect the filling of the drug powder. The elastic band 24 has good elasticity. When a certain part of the perineum swells and bulges, the band in that area will be stretched, thereby causing the dressing 2 to bulge locally to conform to the shape of the swelling; when the swelling subsides, the band will contract and return to its original shape, so that the dressing 2 will flatten and conform to the skin again. This adaptive stretching property ensures that regardless of changes in swelling, the dressing 2 maintains good contact with the skin, and the powder will not shift or accumulate due to changes in swelling, always covering the area requiring treatment evenly.
[0033] like Figure 5As shown, the breathable nonwoven fabric layer 25, in addition to securing the elastic band 24, also serves to isolate the medication powder from the skin. Because the nonwoven fabric itself has numerous micropores, it allows the medication components to penetrate the skin while preventing direct contact between the medication powder particles and the skin, thus reducing friction and irritation. Simultaneously, the excellent breathability of the nonwoven fabric ensures that the perineal skin can breathe normally, preventing local dampness and stuffiness caused by prolonged contact with the medication pack, and reducing the possibility of infection. Therefore, the breathable nonwoven fabric layer 25 plays a crucial role in improving user comfort and safety.
[0034] The partition 13 of this utility model has also been structurally optimized. For example... Figure 6 As shown, the partition 13 is preferably composed of multiple layers of materials, including, from the outside to the inside, an outer cotton layer 132, an absorbent layer 133, and a breathable layer 134. The outer cotton layer 132 is made of soft, skin-friendly cotton fabric and is located on the outermost side of the partition 13 (i.e., the side closest to the dressing 2). The function of the outer cotton layer 132 is to protect the dressing 2 from direct soiling by lochia or secretions. When lochia flows out, it first comes into contact with the outer cotton layer 132, which absorbs some of the liquid and prevents it from quickly seeping into the dressing 2, thereby extending the effective use time of the dressing 2 to some extent. The absorbent layer 133 is located inside the outer cotton layer 132 and is usually made of highly absorbent materials, such as fluff pulp, superabsorbent polymer (SAP), or fluffy cotton. The absorbent layer 133 has strong absorption capacity, quickly absorbing liquid that permeates through the outer cotton layer and locking it inside, preventing leakage. In this embodiment, the thickness and area of the absorbent layer 133 are designed according to actual needs to ensure that it can accommodate the large amount of lochia in the early postpartum period without leakage. The breathable layer 134 is located on the innermost side of the partition 13 (the side closest to the skin) and is generally made of breathable non-woven fabric or mesh fabric. The function of the breathable layer 134 is to allow the perineal skin to exchange with the outside air to a certain extent, preventing the area from becoming too moist and stuffy due to the presence of the partition 13. At the same time, the surface of the breathable layer 134 is smooth and soft, and will not cause irritation when in direct contact with the skin. Through the close fit of the outer cotton layer 132, the absorbent layer 133 and the breathable layer 134, the partition 13 as a whole has both good absorption performance and ensures a certain degree of breathability, keeping the perineum dry and comfortable, and greatly reducing the risk of infection.
[0035] In addition, to prevent the underwear from slipping or shifting during wear, this invention has a non-slip elastic strip 15 sewn onto the inner side of each of the two thigh roots of the underwear body 1 (see...). Figure 1The anti-slip elastic strip 15 is typically made of elastic material, such as an elastic band with silicone particles, and is approximately 5-10 cm long. It is fixed to the edge of the underwear along the curve of the groin. When the underwear is put on, the anti-slip elastic strip 15 gently grips the inner thigh skin. Due to its surface friction, it effectively prevents the underwear from slipping down. Especially when the user gets up or walks, the resistance provided by the anti-slip elastic strip 15 ensures that the underwear stays in the correct position and does not shift due to movement, thus ensuring that the dressing 2 is always aligned with the perineum. This is particularly important for patients or postpartum women who have limited mobility after surgery and need to rest in bed frequently, as it prevents the dressing from shifting due to underwear movement, which could affect the treatment effect.
[0036] When using this invention, the following steps can be followed: First, fill appropriate amounts of rhubarb and Glauber's salt powder into each of the filling areas 22 of the dressing 2. The amount of powder in each area can be adjusted according to the specific swelling of the perineum—for example, if the left side is significantly swollen, fill the left area with more powder; if the right side is not significantly swollen, fill the right area with less powder or none at all. After filling, close the Velcro 211 of each opening 21 to ensure that the powder does not leak out. Next, place the dressing 2 into the storage space 14 of the underwear body 1, aligning the buttons 26 on the dressing 2 with the connecting holes on the partition 13 and fastening them to secure the dressing 2. Then, put on the underwear normally and adjust the position so that the dressing 2 faces the perineum. At this time, the breathable layer 134 of the partition 13 directly contacts the perineal skin, and the dressing 2 is located on the outside of the partition 13; the two are tightly attached together by the buttons. During daily activities or bed rest, the rhubarb and Glauber's salt powder inside the dressing 2 will slowly act on the perineal skin through the breathable layer 134 of the partition 13, exerting the effects of reducing swelling and pain, and anti-inflammatory and antibacterial properties. At the same time, the absorbent layer 133 of the partition 13 will absorb secretions such as lochia, keeping the perineal area clean and dry. When it is necessary to change the powder or the dressing, simply unbutton 26 to remove the dressing 2, open the Velcro 211 to pour out the old powder, refill the dressing or replace it with a new one, and then put it back on as described above.
[0037] It should be noted that the rhubarb and Glauber's salt powder used in this invention can be adjusted according to specific needs. Furthermore, the size and shape of the dressing 2 and the partition 13 can be optimized according to the body shape of different groups (such as postpartum women or postoperative patients) to provide better fit and comfort. The fabric of the underwear body 1 is preferably made of soft and breathable cotton fabric with good elasticity to adapt to changes in postpartum body shape and ensure wearing comfort.
[0038] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
