Wound irrigation and drainage treatment system and method with painless and potent mode

Abstract

The invention relates to a wound irrigation and drainage treatment system and method with a painless and potent mode. The system comprises a control circuit; the output / input end of the control circuit is respectively connected with and drives the negative pressure pump and the flushing pump; the negative pressure output end of the negative pressure pump is communicated with the hydrops tank and provides negative pressure for the hydrops tank; the hydrops tank is communicated to a wound dressing through a suction pipeline and is used for sucking drainage liquid under negative pressure; a clamping switch is arranged on the suction pipeline between the hydrops tank and the wound dressing; the control end of the clamping switch is connected to the output end of the control circuit and used for controlling the speed of opening or closing the suction pipeline. The input end of the flushing pump is communicated with a flushing fluid source and is used for obtaining flushing fluid; the output end of the flushing pump is communicated with the wound dressing and used for providing flushing fluid for the wound dressing. A potent mode and a painless mode are added in the intermittent suction mode and the flushing and soaking mode, different modes are selected according to different wound conditions, and wound treatment and recovery are facilitated.

Description

technical field [0001] The invention relates to the field of wound tissue treatment, in particular to a painless and powerful wound irrigation and drainage treatment system and method. Background technique [0002] Vacuum-sealing drainage (VSD), which has emerged in recent years, has been clinically validated and can be applied to the coverage and drainage of acute and chronic wound ulcers and large soft tissue defects. It can also be applied to traumatic osteomyelitis. Nature enters the clinician's approach to treatment. VSD wound covering materials currently on the market are mainly biosynthetic materials of foam or sponge, which cannot remove viscous exudate and necrotic exfoliated tissue during application. The most likely problem is that the drainage tube is blocked, which leads to an increase in the number of bacteria, The peculiar smell is obvious, which is not conducive to wound healing. [0003] Effective wound washing combined with negative pressure therapy can h...

AI Technical Summary

Problems solved by technology

Since the wound surface is always in a state of flushing and suction, the liquid that has just reached the wound surface has no time to dissolve wound exudate, necrotic tissue, bacteria, and toxins, and the flushing fluid will be sucked away, resulting in poor flushing effect

When the patient has obvious pain on the wound surface, the negative pressure on the wound surface needs to reach the target value slowly. The negative pressure acts on the wound surface more gently, reducing the stimulation of the wound surface and reducing the pain. At present, the clinical product first releases the negative pressure on the wound surface and the fluid accumulation tank through the vent. The pressure valve releases the negative pressure, wasting the negative pressure formed by the consumption of electric energy by the negative pressure pump, and then slowly starts the negative pressure pump to gradually form negative pressure, the whole process is complicated and consumes electricity

With flushing function, clinical routine negative pressure drainage equipment, the negative pressure of the wound changes with the negative pressure in the fluid tank. Due to the limited power of the negative pressure pump, it is impossible to quickly reach the target high negative pressure in the wound and fluid tank value, for wounds with heavy infection and many necrotic tissues, negative pressure should be quickly formed on the wound surface, and the fast-flowing liquid flow in the form of exudate and necrotic tissue will have a strong flushing effect on the wound surface, dressings and pipelines, and the necrotic tissue will be carried away. Out of the body, reducing blockage, the negative pressure drainage treatment equipment in the current market and existing technology cannot meet this demand
