Wound exudate weight detection method and negative pressure wound therapy equipment thereof

Abstract

According to the embodiment, the invention provides a wound exudate weight detection method. The negative pressure wound therapy equipment comprises a liquid collection box and a weight detection device which is used for detecting weight information of wound exudates in the liquid collection box; and the wound exudate weight detection method comprises the following steps: measuring the weight of the empty liquid collection box by virtue of a mass sensor on the weight detection device; measuring the weight of the liquid collection box which is filled with the wound exudates of a patient by virtue of the mass sensor; and after therapy, acquiring the total weight of the wound exudates sucked by the negative pressure therapy equipment. According to the embodiment, the invention also correspondingly provides the negative pressure wound therapy equipment. According to the embodiment, by virtue of the wound exudate weight detection method as well as the negative pressure wound therapy equipment and a therapy system provided by the invention, precise measurement on the weight information of the wound exudates in the liquid collection box can be achieved, and manual weighing operation and recording can be avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for detecting the weight of wound exudate and negative pressure wound treatment equipment thereof. Background technique [0002] Negative Pressure Wound Therapy (NPWT) is an advanced wound treatment developed in recent years. It mainly promotes wound healing by applying low negative pressure (generally -55mmHg to 175mmHg) to the wound. Specifically, negative pressure attracts the cell membrane, which can expand and distort it. The cell is considered damaged, and the information of damage is transmitted to the nucleus. Through signal conversion, it causes the cell to secrete pre-healing growth factors, including vascular proliferation factors, thereby stimulating tissue Produce more new blood vessels; in addition, negative pressure suction absorbs the exudate from the wound to help establish the liquid balance of the wound; it can also provide a moist environment, remove...

AI Technical Summary

Problems solved by technology

[0004] At present, there are mainly two types of weight measurement for wound exudate. One is to remove the liquid collection box and weigh it when measurement is required, and manually record the weight of each weighing, which is inconvenient and cumbersome to operate; The electronic scale is installed under the liquid collection box. The structure of the electronic scale is relatively heavy, which increases the difficulty of processing the main body of the negative pressure therapy equipment.
