The liquid volume detection method comprises the following steps: acquiring an inclination angle theta of a liquid storage bottle, a first capacitance value C1 measured by a first measuring electrode and a second capacitance value C2 measured by a second measuring electrode; judging whether the inclination angle theta is less than or equal to a first preset angle or not; when the inclination angle theta is less than or equal to the first preset angle, working out liquid volume L in the liquid storage bottle according to the first capacitance value C1 and the second capacitance value C2. The liquid volume detection method and the liquid volume detection device disclosed by the invention have the advantage of being high in detection precision.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a liquid volume detection method and device for negative pressure wound treatment equipment. Background technique [0002] Negative pressure wound therapy equipment mainly uses negative pressure as the source of suction to absorb the effusion around the wound by means of continuous or intermittent suction, and stores the effusion (exudate) in the liquid storage tank, so that it can effectively increase the wound surface. Blood flow is beneficial to reduce tissue edema and promote wound healing. It has a good curative effect in the treatment of soft tissue contusions of extremities, diabetic foot and carbuncle, deep pressure sores, ulcers, skin grafting and plastic surgery. [0003] At present, the liquid level and liquid volume detection methods in the liquid storage tank are basically measured by capacitive liquid level gauges. For example, the Chinese patent applicatio...
