Method and device for detecting weight of wound exudate as well as negative pressure treatment system

Abstract

The invention provides a method for detecting weight of wound exudate. The method is used for detecting weight information of wound exudate in an exudate collecting box and comprises steps as follows: when the exudate collecting box doesn't contain the wound exudate, the identification code of the exudate collecting box is acquired, and the weight of the empty exudate collecting box is acquired; after treatment for preset time, when the exudate collecting box contains the wound exudate, the identification code of the exudate collecting box is acquired again, and the weight of the exudate collecting box containing the wound exudate is measured; the weight of the wound exudate is acquired and sent to a negative pressure treatment device connected with the exudate collecting box. The exudate collecting box can be automatically paired with a patient and the negative pressure treatment device by means of the provided method and device for detecting the weight of the wound exudate as well as a negative pressure treatment system, the accurately measured weight of the wound exudate in the exudate collecting box is shared, and effective reference is provided for adjustment and treatment.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a wound exudate weight detection method, device and negative pressure treatment system. 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 necrotic tissue, an...

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.
