Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an adjustable axillary pressure bandage for post-operative breast cancer surgery. Background Art

[0002] Breast cancer is the most common malignancy in women. For breast cancer patients, surgery is the most effective and fundamental treatment option. For breast cancer patients with axillary lymph node metastasis, axillary lymph node dissection is the most fundamental surgical treatment option to assess axillary lymph node status. With the pursuit of beauty among modern women, breast-conserving surgery and prosthetic reconstruction are becoming increasingly common. During these procedures, the chest area often requires minimal or only short-term compression bandaging. Therefore, effective compression bandaging of the axillary area is focused on avoiding the discomfort associated with concurrent breast pressure. However, conventional bandages cannot achieve the desired effect of isolated axillary pressure bandages or provide additional axillary pressure in addition to chest bandages. Some breast surgeons prefer gauze bandages to enhance axillary pressure bandages, but these bandages can easily cause allergic reactions in the axillary area, leading to complications such as itching, rashes, and blisters. If a conventional chest strap is used, the strap will get stuck in the skin of the armpits, causing discomfort to the patient after prolonged wearing. Local friction can lead to blisters, and even redness, swelling, pain, skin breakage, and exudation. At the same time, some patients do not have shoulder straps, which causes the straps to slip off due to inadequate fixation. This results in ineffective pressure application, aggravating the formation of effusion and lymphatic fistula, affecting the patient's postoperative recovery, and thus affecting the comprehensive treatment of breast cancer patients in the later stages. For example, the utility model disclosed in the authorization announcement number CN209951573U discloses an adjustable local pressure support for breast cancer surgery, comprising a chest wall pressure support and an axillary pressure support; the chest wall pressure support is a flat cushion-like structure; the axillary pressure support is an ellipsoidal structure, comprising a soft outer layer and a hard inner core, the hard inner core being disposed inside the soft outer layer and fixedly connected to the soft outer layer; the surface of the chest wall pressure support and the soft outer layer of the axillary pressure support also have an anti-slip structure. This design can perfectly fit the armpit and chest wall structure of patients of various body shapes, while ensuring appropriate pressure. The anti-slip surface design prevents it from falling out and affecting the treatment effect.

[0003] The above technical solution has the following problems: during use, the pressure applied to the axillary area cannot be adjusted according to the actual condition of the patient's axillary skin, and the pressure cannot be controlled. Moreover, it can only be worn on one shoulder. Long-term wear can easily cause friction in the axillary area, which can increase the incidence of complications such as axillary blisters, redness, swelling, pain, fluid accumulation, and lymphatic fistulas. Moreover, it cannot effectively apply pressure to the axillary area alone, especially for patients undergoing prosthetic reconstruction. Therefore, we propose an adjustable axillary pressure bandage for breast cancer surgery. Utility Model Content

[0004] The purpose of the present utility model is to provide an adjustable axillary pressure bandage after breast cancer surgery, so as to solve the problems raised in the above-mentioned background technology that, during use, the axillary pressure cannot be adjusted according to the actual situation of the patient's axillary skin, the pressure cannot be controlled, and the bandage can only be worn on one shoulder. Long-term wearing of the bandage easily causes friction to the axillary area, which can easily lead to the incidence of complications such as blisters, redness, swelling and pain in the axillary skin. At the same time, it solves the problem of increased incidence of effusion and lymphatic fistula due to ineffective axillary pressure, and solves the problem that only effective pressure needs to be implemented separately in the axillary surgical area of ​​some breast cancer patients.

[0009] Preferably, the adjustment structure includes a positioning column, which is arranged on the front elastic chest strap and the rear elastic chest strap. The front elastic shoulder strap and the rear elastic shoulder strap are both rotatably connected to the positioning column through a ring. The end of the positioning column is also provided with a locking assembly for positioning the angle of the ring, which can adjust the angle of the front elastic shoulder strap and the rear elastic shoulder strap.

[0010] Preferably, the locking assembly includes a locking sleeve, a guide rod is provided in the middle of the locking sleeve, the guide rod is movably provided in the guide groove, the guide groove is provided on the positioning column, locking pins are evenly provided on one side of the locking sleeve, the locking pins are engaged with the locking groove, and the locking grooves are evenly provided on the surface of one side of the ring, which can lock the angles of the front elastic shoulder strap and the rear elastic shoulder strap.

[0011] Preferably, a reset spring is further provided in the guide groove, one end of the reset spring is connected to the guide rod, and can drive the guide rod to reset and move.

[0012] Preferably, a limiting slider is provided on the outer surface of the guide rod, one end of the limiting slider is slidably provided in a limiting slide groove, and the limiting slide groove is provided on the inner wall of the guide groove, which can limit the movement of the guide rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The present application can control the amount of filler according to the specific circumstances of the patient's axillary surgery, thereby controlling the pressure on the axillary surgical area and improving the flexibility of the device.

[0015] (2) The present application can control the angles of the front elastic shoulder strap and the rear elastic shoulder strap and position them, and can change the wearing method, thereby avoiding the continuous friction of the shoulder strap on the armpit skin, reducing the incidence of local armpit pressure blisters and skin breakage, and making the patient's armpit more comfortable.

[0016] (3) This application can be used alone for breast cancer patients who have undergone axillary surgery, especially for patients who have undergone prosthetic reconstruction of breast cancer, because patients only need to perform effective pressure bandage on the axilla to ensure the comfort of the chest (breast).
