Abstract

The invention discloses a miniature negative pressure drainage instrument and an operation method thereof. The drainage instrument comprises a power supply connected with each component, a control panel for controlling opening and closing of each component, an air pump drive arranged on the control panel, a pressure sensor arranged on the control panel, a key switch arranged on the control panel,an air pump connected with the air pump drive and providing negative pressure, and a pipeline which is connected between the air pump and a wound dressing outside the drainage and is connected with the pressure sensor. The operation method comprises the following steps: sending pressure waveform information to a wound surface through the air pump; and then acquiring and collecting the informationthrough the pressure sensor, so that communication among a plurality of machines is realized, starting and stopping of air pumps are adjusted, power distribution among the machines is balanced, and longest working time is provided. Therefore, battery replacement by a patient and a doctor is reduced, energy is saved, and convenience is provided for people.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a miniature negative pressure drainage instrument and an operating method thereof. Background technique [0002] Negative pressure drainage technology is a wound treatment technology developed in recent years. It uses medical foam material to fill the wound surface, covers it with a breathable film, seals the negative pressure and continuously attracts it, and completely isolates the wound from the outside world. It is a method to achieve the purpose of wound treatment by adequate drainage. The application indications include various acute and chronic wounds including infected wounds or wounds, acute soft tissue defects, various chronic (pressure, vascular, diabetic) ulcers, surgical incision dehiscence or skin grafting, etc. Clinical and basic studies have confirmed that the effect is definite. It can inhibit bacterial growth, control infection, reduce wound and periwound tis...
