Abstract

According to the embodiment, the invention provides a working pressure regulating method of negative pressure therapy equipment. The method comprises the following steps: acquiring a preset therapy pressure; identifying an actual pressure, and calculating an adjustment range of the pressure in accordance with the therapy pressure; and when the adjustment range is more than a preset range threshold, executing delayed adjustment, wherein the delayed adjustment is to adjust the pressure of the negative pressure therapy in accordance with a preset pressure adjustment speed. According to the embodiment, the negative pressure therapy equipment, with the implementation, disclosed by the invention has the following beneficial effects: in a process of adjusting the pressure, the pressure is slowly increased or decreased in accordance with a preset threshold, so that discomfort on a patient caused by sharp increase or decrease of the pressure is relieved; and meanwhile, the negative pressure therapy equipment can also automatically set the threshold in accordance with various demands of different patients, and the pressure adjustment speed can be changed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a negative pressure treatment equipment and a pressure adjustment method 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 necrotic tissue, and redu...
