Embodiment Construction

[0031] The present invention will be further elaborated below in conjunction with accompanying drawing, wherein, the direction of the present invention is with figure 1 as standard.

[0032] Such as Figure 1 to Figure 6 As shown, the self-circulating negative pressure drainage system of the present invention includes a medical dressing 1, a drainage system 2, a cleaning system 3, a pressure monitoring system 4 and a pressure balance system 5, and the medical dressing 1 is used to attach to the patient's wound surface ; Drainage system 2 is used to guide the accumulated blood and fluid in the patient's wound site; Cleaning system 3 is used to disinfect and clean the patient's wound site; Pressure monitoring system 4 is used to monitor the actual pressure of the patient's wound site in real time ; The pressure balance system 5 is used to balance the pressure of the patient's wound site to avoid excessive pressure at the wound site.

[0033] Medical dressing 1 can be porous sp...

Abstract

The invention discloses a negative pressure drainage system capable of achieving a self-circulation; the negative pressure drainage system can generate a continuous liquid shearing force in the position of a wound surface, so as to accelerate the union of the wound surface. The negative pressure drainage system comprises a medical dressing, a waste liquid bottle, a vacuum pump, an A liquid conduit, an A air conduit, a B liquid conduit, a peristaltic pump, a C liquid conduit, an infusion bottle, an E liquid conduit, an a control valve, a B control valve and an F control valve, wherein the medical dressing, the B liquid conduit, the peristaltic pump, the C liquid conduit and the infusion bottle are sequentially connected. The medical dressing, the A fluid conduit, the waste liquid bottle, the A air conduit and the vacuum pump are sequentially connected. The E liquid conduit is connected between the C liquid conduit and the A liquid conduit. The A control valve is installed on the A liquid conduit; and the connection point between the E liquid conduit and the A liquid conduit is located between the A control valve and the medical dressing. The B control valve is installed on the C liquid conduit; and the connection point between the E liquid conduit and the C liquid conduit is located between the B control valve and the peristaltic pump. The F control valve is installed on the E liquid conduit.

Description

technical field [0001] The invention relates to a negative pressure drainage system, in particular to a self-circulating negative pressure drainage that can perform nutrient circulation treatment at the wound site, generate continuous fluid shear force, and accelerate the healing of the wound site system. Background technique [0002] In recent years, with the rapid development of the social economy and the acceleration of the aging process of the society, various acute and chronic skin wounds that are difficult to heal, such as diabetic foot ulcers, deep pressure ulcers, and post-traumatic wounds, have also increased. Wounds that leak a lot of fluid and need to be drained often appear after surgery. Accumulation of blood, pus, interstitial fluid or secretions occurs at the lesion or wound. If these liquids are not removed in time, it will affect the healing of the wound, and even worsen the wound in severe cases. The effective solution is to use The negative pressure drai...
