Description

一种乳腺外科术后用固定胸带A chest belt for fixing after breast surgery

技术领域Technical Field

本实用新型属于医用胸带领域,具体地说是一种乳腺外科术后用固定胸带。The utility model belongs to the field of medical chest belts, in particular to a chest belt for fixing after breast surgery.

背景技术Background Art

乳腺癌是女性常见的恶性肿瘤,临床上通过切除手术达到根治的目的,但是切除造成的创伤面较大,为避免继发出血及切口愈合不良,手术完成后需要对切口进行敷料并包扎。Breast cancer is a common malignant tumor in women. It is clinically cured by resection surgery. However, the trauma caused by resection is large. In order to avoid secondary bleeding and poor wound healing, the incision needs to be dressed and bandaged after the operation.

目前主要采用的包扎方式为:切口及周围覆盖无菌纱布,再以消毒棉纱覆盖,然后用绷带在患者胸部以及肩部呈八字形状层叠缠绕进行加压包扎,在包扎时,需要将绷带用力缠绕,使切口边沿的皮肤向切口中心聚拢,防止创口处皮肤及肌肉呈拉伸紧绷状态,影响伤口愈合;该种绷带包扎方式操作繁琐,且在换药时需要将整个绷带依次完全拆开,费时费力。At present, the main bandaging method used is: covering the incision and the surrounding area with sterile gauze, then covering it with sterilized cotton gauze, and then using bandages to wrap around the patient's chest and shoulders in an eight-shaped layer for pressure bandaging. When bandaging, the bandage needs to be wrapped tightly to make the skin at the edge of the incision gather toward the center of the incision to prevent the skin and muscles at the wound from being stretched and tight, which affects wound healing. This bandage bandaging method is cumbersome to operate, and the entire bandage needs to be completely removed in sequence when changing the dressing, which is time-consuming and laborious.

另外,若仅有一侧乳房出现病变,只需将出现病变的乳房切除,将未发生病变的乳房保留,但上述绷带在缠绕包扎时,会将两侧乳房位置全部包裹,且将绷带用力收紧包扎时,未发生病变的乳房会被勒紧,造成不适。In addition, if only one breast has a lesion, only the breast with the lesion needs to be removed, and the breast without the lesion needs to be retained. However, when the above-mentioned bandage is wrapped, the position of both breasts will be completely covered, and when the bandage is tightened, the breast without the lesion will be tightened, causing discomfort.
