Description

Technical Field

[0001] The invention relates to the technical field of medical care, in particular to an anti-compression bra for postoperative care of breast cancer. Background Art

[0002] Breast cancer is a common malignant tumor that endangers women's health. Usually, a bandage is needed to apply pressure after breast cancer surgery. In the prior art, ordinary inelastic gauze bandages and elastic bandages are used to apply pressure to patients after breast cancer surgery. This bandaging method requires multiple people to operate when bandaging the patient, which wastes manpower. At the same time, the bandaging speed is slow, time-consuming and labor-intensive. At the same time, the tightness of the pressure bandage is not easy to control, so that the separated skin flap cannot be close to the chest wall and the chest wound. If the bandage is too loose, the purpose of pressure hemostasis cannot be achieved. If the bandage is too tight, the blood circulation of the affected upper limb is affected, and sometimes even breathing may be restricted, which can easily lead to postoperative subcutaneous effusion, skin flap necrosis, limb dysfunction and edema, thereby prolonging the patient's recovery time.

[0003] After searching, a pressure bra capable of protecting nipples is proposed in patent publication number CN221331667U, which relates to the field of medical supplies. The pressure bra capable of protecting nipples includes a bra half, shoulder straps, a front connector, a rear connector and a thickened pad; there are two bra halfs, which are spaced apart in the left and right directions, and the bra half has a breast front part, which includes a breast front inner layer and a breast front outer layer, and the thickened pad is arranged between the breast front inner layer and the breast front outer layer, and the breast front inner layer, the breast front outer layer and the thickened pad are all provided with nipple holes; the front connector connects the front parts of the two bra halfs, and the distance between the two bra halfs is adjustable; the rear connector connects the rear parts of the two bra halfs, and the rear connector is elastic; the shoulder straps are arranged one-to-one with the bra halfs, the shoulder straps are located above the bra halfs, and the two ends of the shoulder straps are respectively connected to the front and rear parts of the bra halfs, and the length of the shoulder straps is adjustable.

[0004] However, the bras in the above patent documents have a relatively simple structure, mostly a belt structure, fixed by adhesive tapes at both ends, and have obvious disadvantages. Because it is an integrated structure, it is inconvenient to adjust the compression on the chest. Due to the high compression force required, it often causes abrasion to the skin, resulting in problems such as blisters. Not only that, when the dressing needs to be changed, the doctor needs to disassemble it as a whole for operation. Repeatedly putting on and taking off the bra is not only not conducive to the patient's recovery, but also increases the workload of medical staff and is not conducive to use. Contents of the invention. Therefore, there is an urgent need for an anti-compression bra for breast cancer postoperative care. Summary of the invention

[0022] 1. The invention inserts the connecting post on the right connecting belt into the connecting groove on the left connecting belt. When the connecting block on the connecting post contacts the inner wall of the connecting groove, the inner wall of the connecting groove can squeeze the connecting block to compress the connecting spring. At this time, the connecting block will retract into the receiving groove on the side wall of the connecting post until the connecting post completely enters the connecting groove on the left connecting belt. The inner wall of the connecting groove will lose the squeezing force on the connecting block. At this time, under the elastic force of the connecting spring, the connecting block can slide out of the receiving groove to achieve the jamming of the connecting groove. At the same time, the buffer belt is set on the shoulder strap, which is an elastic belt with high-strength elasticity, which fits and tightens the two sides of the patient's shoulders. At the same time, the shoulders provide supporting force to lift the patient's lower chest, effectively avoiding the squeezing of the patient's chest by the entire bra, thereby greatly improving the comfort of the patient wearing the bra.

[0023] 2. The invention, through the setting of the dressing changing port, allows medical staff to change the dressing on the patient's chest without taking off the bra. After the dressing change is completed, the medical staff can insert five fingers into the gripping groove and rotate the locking disk to make the fastening groove on the locking disk and the locking groove be placed in alignment. At this time, under the action of the magnetic attraction of the locking magnetic block in the locking groove, the locking spring will be stretched, and the locking magnetic block will slide out of the inner cavity of the locking groove and enter the locking groove, thereby locking the locking disk and preserving the heat in the entire bra. By setting the end of the locking magnetic block in an arc shape, when disassembling the locking disk, it is only necessary to rotate the locking disk again to misalign the fastening groove and the locking groove, which is convenient and fast, and greatly improves the work efficiency of medical staff.
