AI Technical Summary

Technical Problem

In existing techniques, the pressure points after unilateral mastectomy are prone to slippage and uneven stress, leading to subcutaneous fluid accumulation and hematoma, which affects wound healing. Furthermore, traditional gauze or cotton pads are easily displaced, causing inconvenience to patients.

Method used

A local compression system including an elastic band and compression strips with a positioning mechanism is designed. The positioning mechanism of the locator is connected to the connecting part, combined with the airbag structure and breathable design, to achieve positioning and rotation limit of the breast. The system adopts three-dimensional support with multiple compression strips and underarm compression blocks to adapt to changes in breast size and provide dynamic compression force.

Benefits of technology

It effectively prevents slippage of the compression position, applies force evenly, reduces subcutaneous fluid accumulation and hematoma, improves incision healing, reduces patient discomfort, and simplifies the dressing change process.

Abstract

This invention discloses a local compression hemostatic chest band for unilateral mastectomy, comprising an elastic band that fits over the chest, the band being elastic and wrapping the entire chest, and a shoulder strap that can be adjusted for tightness. The band itself can also be designed for adjustable tightness. It also includes multiple columnar compression strips for right mastectomy. The left ends of the compression strips are connected via a connecting part to a positioning mechanism that fits over the left breast, achieving a fixed-distance limit with the left breast as the center. This restricts the distance to the left breast, allowing rotation only around the left breast, preventing vertical or horizontal movement. The right end of each compression strip is bent backward in an "L" shape to conform to the contour of one side of the chest, achieving rotational limitation. The compression strips are positioned on both sides, with the right end bent backward to conform to the right side of the chest, forming a bend.
