[0003] At present, the negative pressure source on the wall of the hospital or the negative pressure source equipment with large flow in the market can only be used in the hospital. Patients who recover later or have small wounds can be discharged from the hospital. Currently, portable negative pressure equipment is used by patients, but negative pressure drainage is currently available. The drainage box and drainage tube used with the instrument or equipment are disposable, and the price is very high. If the patient needs to use it for a long time, it will bring a certain economic burden to the patient

The invention discloses a negative pressure drainage system, which comprises a shell, a pressure sensor, a drainage tube, flow sensors, a negative pressure pump, a control circuit board and a power supply; both the pressure sensor and the flow sensors are electrically connected with the control circuit board; the shell is provided with a groove for fixing the drainage tube, and all the pressure sensor, the drainage tube, the flow sensors, the negative pressure pump, the control circuit board and the power supply are mounted on the shell; the pressure sensor comprises a pressure probe, a pressure detection steel sheet and an electric induction sheet, the pressure probe is linked to one end of the pressure detection steel sheet, the electric induction sheet is mounted in the middle of the pressure detection steel sheet, and one end of the pressure detection steel sheet is fixed on the shell; and the flow sensors are respectively fixed at two ends of the drainage tube. The invention alsodiscloses a negative pressure drainage method adopting the negative pressure drainage system. The negative pressure drainage system is not in contact with a liquid in the drainage tube and can be repeatedly used, only the drainage bag needs to be replaced when the negative pressure drainage system is in use, and the use cost for a patient is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of negative pressure drainage, in particular to a negative pressure drainage system and a drainage 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, and seals the negative pressure for continuous suction. The wound is completely isolated from the outside world. It is a method for adequate drainage to achieve the purpose of wound treatment. 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 the effect. It can inhibit bacterial growth, control infection, reduce wound and periwound tissue edema, promote...
