**Concept and Function - Refers to a pressure plate/pad made of EVA (ethylene vinyl acetate) foam used for liposuction or postpartum recovery of the waist and abdomen. The common forms include * * waist pads, body shaping boards, waist and abdominal ring suction and compression plates * * that can be placed on the waist and abdomen. Some products are * * hot press integrated molding * *, and there are also * * molded/punched * * styles used in conjunction with elastic clothing. Its core function is to provide uniform and adjustable external pressure to the surgical area, helping to stop bleeding, reduce swelling, promote skin and subcutaneous tissue adhesion, and reduce the risk of early unevenness and bruising, thereby improving the quality of shaping and recovery.**Applicable scenario * * - After liposuction surgery (such as * * waist and abdominal ring suction * *): In the early postoperative period, * * compression bandaging * * is combined with * * elastic clothing * * to reduce exudation and swelling, promote adhesion, and reduce the probability of complications such as * * skin unevenness * * and * * subcutaneous nodules * *.-Postpartum recovery: Some people may use it as an auxiliary tool for abdominal support/compression during cesarean section or early postpartum period to reduce discomfort caused by abdominal traction during activities; But whether it is necessary and how to use it should be based on the individualized assessment of * * obstetricians/rehabilitation doctors * * (this type of product is not a standard medical equipment for postpartum rehabilitation).**Material and specification characteristics * * - Material and process: mainly made of EVA foam * *, can be formed by * * hot pressing/cold pressing/compression molding * *, with common * * compression molding patterns * * on the surface; Some product labels can be combined with XPE. EVA has a sealed foam structure, which makes it non absorbent, moisture-proof, water-resistant, and has characteristics such as shock absorption/buffering, insulation, and sound insulation, making it easy to clean and maintain.-Common specifications: Common shapes on the market include oval, inverted triangle, small waist cushion, diamond, cross, etc; Common sizes include * * 150 x 220 mm, 310 x 230 mm, 300 x 320 mm, 280 x 200 x 13 mm, 300 x 270 x 15 mm, 450 x 230 x 8 mm * *, etc; The colors are mostly black/white, and can also be customized.-Hardness and density: Hardness is usually marked as Shore hardness of 18-60 degrees or P-value of 20-70P (slightly different diameters from different manufacturers); The common density range is about * * 25-80 g/cm ³ * * (different densities correspond to different uses and hardness).**Usage points and precautions * * - Usage positioning: This type of sponge pressure plate is mostly used for * * auxiliary compression/support * *, and should usually be used in conjunction with elastic clothing/shapewear * *, rather than replacing medical grade compression devices separately.-Key points after liposuction: Early postoperative attention should be paid to timely dressing changes and pressure bandaging; Under the advice of a doctor, wear an elastic suit (the common recommendation is to continuously apply pressure for about 1 month after surgery, with the specific duration adjusted according to the recovery situation); Avoid rubbing/pressing the surgical area, and take a normal shower after removing the stitches.-Wearing duration: When used as an auxiliary * * compression cotton pad/pressure plate * *, the common recommendation is * * 1-3 months * *, with significant individual differences, and should be based on the follow-up evaluation of * * the surgeon * *.-Postpartum use: If used for * * cesarean section * * or early postpartum support, it must be selected and used under the guidance of * * doctor/rehabilitation specialist * * to avoid * * tightness * affecting circulation or * * improper pressing * affecting healing.**Selection and medical advice * * - Key points for selection: Pay attention to * * size and shape * * whether they fit the waist and abdomen curve, * * hardness/density * * whether they are suitable (too hard affects comfort, too soft support is insufficient), * * thickness and edge curvature * * (to avoid tenderness and indentation), and * * surface cleanliness * * and * * washability * *.-Medical reminder: This type of item mostly belongs to * * auxiliary rehabilitation equipment * *, not medical devices; For specific plans and stress duration related to postoperative or postpartum recovery, please refer to the individualized guidance of professional doctors. If you experience persistent severe pain, obvious redness, swelling, fever, odor of exudate, or fever, please seek medical attention promptly.
