Description

Breast cancer postoperative pressurization bandaging chest strap

Technical Field

The utility model relates to the technical field of medical and health supplies, more specifically say, it relates to a breast cancer postoperative pressurizes and wraps pectoral girdle.

Background

Breast cancer is a common malignant tumor in gynecology, usually has no obvious symptoms in early stage, and a lump in breast can be found only occasionally, and the tumor usually occurs in one side of breast and sometimes occurs in both sides simultaneously, but is rare. For early diagnosis of breast cancer, the success rate of operation is very high according to the current medical level of China, and the life of a patient can be greatly prolonged, so that the breast cancer is generally treated by the operation. The operation incision is large, generally about 25-35cm, the subcutaneous peeling range is up to clavicle, down to costal arch, inside to sternum side, and outside to anterior edge of latissimus dorsi, bandage is used for pressing and fixing after operation, sufficient drainage is realized, hematocele and hydrops are prevented, and the wound is promoted to heal smoothly.

The bandage used at present is a strip-shaped belt, the chest is tightened and is bonded by gauze and adhesive plaster above the chest, and the pressurizing and fixing method has the advantages that: the structure is simple, the use is convenient, the pressure fixing effect on the chest can be better, but the obvious defects exist, firstly, the pressure hemostasis effect on the armpit can not be realized, and the position is the position of the hematocele and hydrops after the operation, so the hemostasis effect is not good; secondly, the currently used bandage wraps the breasts at two sides simultaneously, namely the bandage wraps the operation part at the affected side and the healthy breast, so that the compression on the healthy breast is increased, the growth and the propagation of cancer cells to the healthy breast are easily promoted, and the disease probability of the healthy breast is increased; thirdly, the bandage is often too loose, too tight or falling off due to the influence of factors such as respiration. In addition, the operation incision is frequently checked, so that dressing waste is caused, and effective drug treatment is lacked during the period of pressure dressing fixation.
