Liquid level control method of wound treating equipment

Abstract

The invention relates to a liquid level control method of wound treating equipment. A pump body works to begin pumping, and the volume of a liquid storage tank and the working state of the equipment are displayed on display equipment, wherein the liquid storage tank is used for storing liquid which flows into the tank due to pumping; the liquid level value in the liquid storage tank and the liquidinflow situation at a gas outlet of the liquid storage tank are obtained; whether the liquid level is larger than a preset upper limit value is or not and whether liquid flows into the gas outlet ofthe liquid storage tank or not are judged; if the liquid level value is larger than the preset upper limit value, the pump body is controlled to stop working and conduct displaying on the display equipment, and alarming equipment is controlled to give out sound-light alarm; if liquid flows into the gas outlet of the liquid storage tank, valves at an oozing liquid inlet and the gas outlet of the liquid storage tank are closed while the pump body is controlled to stop working, and the pump body is then controlled to continue pumping until the liquid level value is smaller than the preset upper limiter value and no liquid flows into the gas outlet. By means of the liquid level control method of the wound treating equipment, the liquid level of the liquid of the liquid storage tank can be monitored in real time, alarming can be conducted, the pump body is automatically controlled, and the liquid of the liquid storage tank is prevented from overflowing.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a liquid level control method for 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] However, the liquid volume of the existing negative pressure wound treatment equipment is mainly recorded and confirmed by the medical staff observing the preset scale on the liquid storage tank, so as to prevent the liquid from ov...

Problems solved by technology

Therefore, the inclination of the equipment or the personal situation of the medical staff may cause inaccurate actual storage liquid volume in the obtained liquid storage tank. For the equipment liquid storage tank, the alarm cannot be generated in time when there is a large angle of inclination, resulting in storage The liquid in the equipment caused by the overflow of liquid in the liquid tank will easily cause the vacuum pump to fail to work normally, thus affecting the treatment
