Abstract

The invention discloses an anti-blocking sucker type negative pressure drainage device. The device comprises a medical sponge dressing, a sucker, a drainage tube and a flushing tube, the sucker comprises biological semi-permeable membranes and a disc body, and the disc body comprises a disc base, a diversion base and a tube connector; the bottom face of the disc base is disposed on the upper surface of the medical sponge dressing, and the bottom face of the diversion base is in contact with the upper surface of the medical sponge dressing; the diversion base is provided with a plurality of diversion channels; the tube connector comprises a flushing channel and a drainage channel which are mutually independent; the flushing channel and the drainage channel are communicated with the diversion channels respectively; the inner wall of the drainage channel is provided with a plurality of spike parts; one end of the flushing tube is inserted into the flushing channel, and the other end of the flushing tube is provided with a detachable sealing cover; one end of the drainage tube is inserted into the drainage channel, and the other end of the drainage tube is provided with a negative pressure connector. The flushing tube is adopted for cleaning a viscous effluent, and at the same time, the spike parts are arranged for breaking and blocking block-shaped extracts, so that the clogging problem of through holes is effectively avoided, and smooth drainage is ensured.

Description

technical field [0001] The invention relates to a negative pressure drainage device, in particular to an anti-clogging sucker type negative pressure drainage device. Background technique [0002] At present, various acute and chronic wounds and ulcers have a high incidence rate and are common and frequently-occurring diseases. Traditional treatment methods such as wound dressing change and drainage have problems such as wound susceptibility, long cycle, patient pain and heavy workload of medical staff. Negative pressure wound therapy is a new wound treatment technology developed in recent years. The specific treatment method is: use porous wound dressings to cover or fill the wounds with skin or soft tissue defects, and then use medical semi-permeable membranes to seal them to form a wound. In a closed space, the drainage tube is finally connected to a negative pressure source to promote wound healing through controllable negative pressure. The treatment method can acceler...
