Description

Technical Field

[0001] This utility model relates to medical care accessories, specifically to a chest band for fixing and immobilizing the affected limb after breast cancer surgery. Background Technology

[0002] Breast cancer is a phenomenon in which mammary epithelial cells proliferate uncontrollably under the influence of various carcinogenic factors. Its incidence rate ranks first among female malignant tumors. At present, surgical treatment is the preferred treatment option for breast cancer patients, and the choice between total mastectomy or breast-conserving mastectomy is mainly based on the patient's disease progression.

[0003] Radical mastectomy for breast cancer involves a large surgical wound, and postoperative complications such as subcutaneous effusion, bleeding, infection, flap necrosis, and respiratory restriction are common. Subcutaneous effusion is a frequent complication after breast cancer surgery, with an incidence rate of 21.2%–44.8%, most commonly occurring in the axilla, subclavian, suprasternal, and parasternal regions. Subcutaneous effusion can cause separation between the flap and the chest wall, preventing the subcutaneous capillary network from anastomosing with the chest wall vessels, leading to lymphatic leakage between the flap and the thorax, affecting flap survival, and increasing dressing change time and overall cost. Currently widely used bandages, including ordinary bandages, ordinary chest straps, elastic bandages, and inflatable chest straps, are complex, time-consuming, and uncomfortable. Furthermore, due to the unique structural features of the chest, uneven local pressure bandage application can lead to loosening, failure to secure drainage bags, and displacement. Therefore, we have designed a postoperative pressure chest strap for breast cancer to improve the comfort of postoperative incision bandaging for breast cancer patients, facilitate drainage bag fixation, and improve treatment outcomes. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a chest band specifically designed for immobilizing and fixing the affected limb after breast cancer surgery. This band uses segmented pressure fixation to reduce bleeding and fluid accumulation, and promote tissue healing. Simultaneously, it restricts the movement of the upper arm and chest, fixes the height of the drainage bag, and prevents wound dehiscence or infection due to traction.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a chest band for immobilizing and pressurizing the affected limb after breast cancer surgery, comprising a chest band body, shoulder straps 1, and limb immobilization straps 2. The chest band body is ergonomically designed using a three-dimensional cutting method and made of elastic material, including a chest band back 3, armpit sections 4, elastic pressure bands 5, and free pressure bands 6. The chest band back 3 is located in the middle of the chest band body. The armpit sections 4 are provided on both sides of the upper part of the chest band back 3, extending outwards. Symmetrical elastic pressure bands 5 are provided on both sides of the armpit sections 4, and Velcro 7 is sewn to the ends of the elastic pressure bands 5 on both sides. The armpit sections 4 have a smooth curve outline. Symmetrical free pressure bands 6 are provided on both sides of the lower part of the chest band back 3, and Velcro 7 is provided at the tail end of the free pressure bands 6 for covering the abdomen. The lower left and right sides of the free pressure belt 6 are provided with zippers 8, and long strips of adhesive 10 are provided at the lower ends of the zippers 8 on both sides to facilitate the placement of drainage tubes and hanging of drainage bags.

[0006] The shoulder strap 1 is symmetrically sewn to the upper end of the back 3 of the chest strap. The other end of the shoulder strap 1 is attached. The shoulder strap 1 is 35-40cm long and 8-10cm wide.

[0007] The limb fixation strap 2 is sewn to the back of the chest strap 3 at the horizontal level of the right axillary line and behind the elastic compression strap 5. Two parallel Velcro straps 7 are set at a certain distance at the end for fixing to the affected arm. The limb fixation strap 2 is made of elastic and breathable material, with a length of 75-80cm and a width of 10cm.

[0008] The unfolded length of the chest band body is 80-100cm. The horizontal length of the chest band back 3 is 30-40cm and the vertical length is 40-45cm. The sum of the lengths of the armpit part 4 and the elastic pressure band 5 on one side of the upper part of the chest band body is 25-30cm, and the width of the elastic pressure band 5 is 23-25cm. The lengths of the free pressure bands 6 on both sides of the lower part of the chest band body are 25-30cm and the width is 17-20cm.

[0009] The outer layer of the elastic pressure band 5 and the outer layer of the free pressure band 6 are made of fleece, and the inner layer of the chest band is made of skin-friendly cotton. The outer edge of the chest band is designed with a double-sided structure 9 to prevent curling.

[0010] To further prevent curling, a vertical elastic support strip 11 is sewn to the lower part of the back 3 of the chest strap.

[0011] Place the chest strap back 3 against the back, then fold one side of the elastic compression band 5 against the chest. Fold the other side of the elastic compression band 5 against the velvet surface of the elastic compression band 5 against the chest. Pull down the shoulder straps, adjust their position, and then attach them to the outer side of the elastic compression band 5. Next, fold one side of the free compression band 6 against the abdomen, then fold the other side of the free compression band 6 against the velvet surface of the free compression band 6 against the abdomen. This completes the dressing. Place a cotton pad on the affected side to increase pressure. Finally, fix the limb fixation band 2. If it is a right-side surgery, wrap it around the patient's right arm and attach it to the elastic compression band 5 on that side using the front Velcro. If it is a left-side surgery, wrap it around the left arm from the opposite side and attach it to the elastic compression band 5 on that side using the end Velcro. The arm that needs to be restricted can be adjusted according to the direction of the patient's affected side.

[0012] The beneficial effects of this application are: ① The limb fixation and compression chest bandage after cancer surgery is designed with ergonomics and adopts a three-dimensional cutting method. It can apply even and moderate pressure to the special structure of the chest after breast cancer surgery, so that the entire wound surface is well attached. The elastic compression band uses elastic fabric to apply pressure to the wound evenly, tightly, without constriction or displacement. The inner layer is made of cotton to prevent skin allergies and is soft and comfortable to wear.

[0013] ② Zippers are provided on both sides of the lower part of the free pressure band to facilitate placing the drainage tube on the outside for observation. Velcro is designed at the lower end of the zippers on both sides to hang the drainage bag, which makes it easy to fix the height of the drainage tube and carry it.

[0014] ③ Postoperative immobilization and compression chest strap for breast cancer surgery: Proper immobilization of the affected limb with a chest strap effectively prevents abduction, promoting rapid wound healing in the axilla. The chest strap restricts shoulder joint movement on the affected side, preventing abduction and reducing shoulder activity, thus lowering the incidence of subcutaneous effusion after breast cancer surgery. It does not affect elbow or wrist joint movement, does not restrict basic mobility, shortens postoperative catheterization time, promotes wound healing, and reduces patient suffering and financial burden.
