Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for the treatment of lymphedema, and in particular to an underwear for treating vulvar lymphedema by incorporating high-density foam. Background Technology
[0002] Cervical cancer is one of the most common malignant tumors in women, second only to breast cancer in incidence, and has the highest mortality rate among female malignant tumors. Early-stage cervical cancer is treated with a comprehensive approach, primarily surgery and radiotherapy, supplemented by chemotherapy. Post-treatment patients face numerous complications, among which lower extremity lymphedema is a common one. After radical hysterectomy for common ovarian cancer, endometrial cancer, and cervical cancer, the iliac lymph nodes in the pelvis are often dissected, while the inguinal lymph nodes are frequently destroyed by radiation. Patients may develop unilateral or bilateral lymphedema in the lower extremities, perineum, and groin at different stages after treatment. MRI scans show a reduced number of inguinal lymph nodes, irregular shapes, and heterogeneous internal texture. Extensive fluid accumulation in the groin, perineum, and groin, accompanied by significant fibrosis around the lymph nodes, and disordered lymph node structure after irradiation.
[0003] Comprehensive anti-edema treatment can effectively reduce lower limb edema, but its effectiveness is poor for cases of lymphedema in the groin, lower abdomen, and vulva. In particular, due to the sensitive location, vulvar lymphedema is difficult to control, CDT (dilation and compression therapy) is more challenging to implement, and the progression of the disease is harder to manage. If lower limb lymphedema is treated simultaneously, the use of elastic bandages or air pumps for compression therapy often exacerbates edema in the groin, perineum, and groin.
[0004] Currently, while short, elastic-fitting pants used daily by patients can provide some assistance, they suffer from several drawbacks, including easy deformation after washing, high price, and generally only daytime use. Furthermore, wearing these pants often results in noticeable swelling, pain, and numbness in the limbs, requiring many patients to remove them after 2-3 hours to relieve pressure. Another option involves multiple layers of bandages combined with homemade T-shaped high-density foam, which addresses some issues to a certain extent, but introduces new problems such as inconvenience with urination and defecation, and the process is cumbersome for patients to perform themselves, making long-term adherence difficult. Utility Model Content
[0005] The purpose of this invention is to propose an underwear designed to treat vulvar lymphedema caused by high-density foam compression, in order to solve one or more technical problems existing in the background art.
[0006] To achieve this objective, the present invention adopts the following technical solution:

Detailed Implementation
[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0025] This embodiment describes an underwear designed to reduce vulvar lymphedema by incorporating high-density foam compression. (See attached image.) Figure 1 and 2 The underwear includes a main body 1, a first empty pocket 2, two second empty pockets 3, two third empty pockets 4, and multiple pressure blocks. The main body 1 includes a front panel 11, a back panel, a crotch panel 12, a waistband 13, and two leg openings 14, all sewn together as one piece. The first empty pocket 2 is sewn to the middle of the front panel 11 and extends from the lower edge of the waistband 13 to the upper edge of the crotch panel 12. The surface of the first empty pocket 2 has a first opening 21. The two second empty pockets 3 are respectively sewn to the front panel 11 at the position corresponding to the groin area of the human body. The surface of the second empty pockets 3 has a second opening 31. The two third empty pockets 4 are respectively sewn to the leg openings 14 at the position corresponding to the root of the human thigh. The surface of the third empty pockets 4 has a third opening 41. Multiple pressure blocks are placed in the first empty pocket 2, the second empty pocket 3, and the third empty pocket 4 through the first opening 21, the second opening 31, and the third opening 41, respectively.
[0026] By incorporating a first empty pocket 2, a second empty pocket 3, and a third empty pocket 4 on the underwear body 1, corresponding to lymphedema-prone areas such as the vulva, groin, and groin respectively, the pressure block is evenly applied to these areas, achieving precise pressure on these edema-prone regions. The pressure block can be easily inserted or removed through the opening, allowing adjustment of the pressure intensity according to the patient's actual edema condition for better therapeutic results. Compared to traditional elastic pants, this new type of underwear can be worn during the day, and the pressure block can be removed only when pressure relief is needed, eliminating the need for periodic removal like traditional elastic pants. Furthermore, the underwear is very convenient to put on and take off, without placing any extra burden on the patient.
[0027] Preferably, the underwear in this embodiment also includes two first elastic bands 51, a first buckle 52 and a first fastening assembly. One end of the two first buckles 52 is sewn to both sides of the front panel 11, and one end of the two first elastic bands 51 is sewn to both sides of the crotch 12. The other end of the first elastic band 51 is fastened to the first buckle 52 located on the opposite side by the first fastening assembly, so that the first elastic band 51 covers the surface of the second empty pocket 3.
[0028] Two first elastic bands 51 are respectively fastened to the first buckle 52 on the opposite side via the first fastening assembly, so that the two first elastic bands 51 cross each other and cover the surface of the second empty bag 3 on the opposite side. This is used to press the pressure block inside the second empty bag 3, thereby applying additional pressure to the groin area. The cross-pressure applied to the vulva can further reduce swelling by using gradient pressure from the vulva to the abdomen, resulting in a significant swelling reduction effect. Specifically, the first elastic bands 51 are sewn to the front outer side of the crotch and along the hem to the midpoint of the thigh.
[0029] Furthermore, the first fastening assembly includes a first male buckle 53 and a first female buckle 54. Multiple rows of first male buckles 53 are sewn to the other end of the first buckle strap 52, and first female buckles 54 are sewn to the first elastic band 51. The first male buckles 53 and the first female buckles 54 are fastened together.
[0030] The first elastic band 51 and the first buckle 52 are fastened by the cooperation of the first male buckle 53 and the first female buckle 54. The first male buckle 53 is provided with multiple rows, and the corresponding pressure can be selected according to the individual's choice or the degree of edema reduction, so as to meet the treatment needs of different degrees of edema.
[0031] Preferably, the underwear in this embodiment further includes a second elastic band 61, a second buckle 62, and a second fastening assembly. The second buckle 62 and the second elastic band 61 are respectively sewn onto both sides of the same pant leg 14. The second elastic band 61 and the second buckle 62 are fastened together by the second fastening assembly, so that the second elastic band 61 covers the surface of the third empty pocket 4.
[0032] A third hollow pocket 4 is formed by creating a double-layered hollow cotton-polyester loop approximately 5-8 cm from the groin area of the pant leg 14. Two second elastic bands 61 are respectively fastened to second buckles 62 on the same groin leg 14 via second fastening components, so that the second elastic bands 61 cover the surface of the third hollow pocket 4, pressing the pressure block inside the third hollow pocket 4 to apply additional pressure to the groin area. This solves the problems of existing elastic pants failing to reduce swelling in the groin area, elastic bandages being difficult to wrap around the groin, and women having difficulty urinating and defecating, and easily getting the elastic bandages dirty. In this embodiment, after the pressure block is applied using the third hollow pocket 4, the second row of buckles and the second elastic bands are used to ensure the pressure effect. The pressure can be adjusted by choosing whether to fasten the second elastic band and the second row of buckles according to individual needs. The first elastic band 51, the second elastic band 61, the first buckle 52, and the second buckle 62 are made of low-elasticity bandages to provide additional support or fastening effect, so that the pressure block fits tightly against the human body and improves the pressure effect.
[0033] Preferably, the second fastening assembly includes a second male buckle 63 and a second female buckle 64. The second male buckle 63 is sewn onto the second elastic band 61, and the second female buckle 64 is sewn onto the second buckle strap 62. The second male buckle 63 and the second female buckle 64 are fastened together. The second elastic band 61 and the second buckle strap 62 are fastened together through the cooperation of the second male buckle 63 and the second female buckle 64. This allows for the selection of whether to apply pressure to the groin area based on individual choice or the degree of edema reduction, thus meeting the treatment needs of different degrees of edema.
[0034] Preferably, the underwear in this embodiment further includes a first zipper 7, a second zipper 8, and a third zipper 9. The first zipper 7 is sewn at the first opening 21, the second zipper 8 is sewn at the second opening 31, and the third zipper 9 is sewn at the third opening 41. By sewing the first zipper 7, the second zipper 8, and the third zipper 9 to the first opening 21, the second opening 31, and the third opening 41 respectively, the pressure block is confined within the area requiring pressure, ensuring that the pressure block does not easily slip out.
[0035] Preferably, the inner side of the underwear body 1 is sewn with an inner layer made of cotton material. This ensures that the underwear is made entirely of cotton material close to the skin, improving wearing comfort. The underwear body 1 is formed by sewing the front panel 11, back panel, crotch 12, waistband 13, and two leg openings 14 together to form a high-waisted or boxer briefs, with the leg openings 14 extending 5-10 cm from the bottom of the leg.
[0036] Preferably, the pressure block is made of high-density foam. In this embodiment, a pressure block made of high-density foam is used as the main pressure material for edema. It can be cut to the shape according to the location of lymphedema. It can be inserted into the pressure site or removed at any time through the first opening 21, the second opening 31 and the third opening 41. After removing the pressure block, it is convenient to wash the patient's underwear and keep the patient's vulva clean and hygienic.
[0037] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
