Abstract

The invention discloses a special miniature negative pressure adjustable drainage device for microscopic hand and foot surgery department, and belongs to the technical field of medical care. The special miniature negative pressure adjustable drainage device comprises a flushing tube, a drainage tube, a liquid storage container and a negative pressure generating device, wherein the negative pressure generating device comprises two push injection tube bodies; piston heads in the two push injection tube bodies are respectively positioned at the bottom and the top in the push injection tube body;a regulating assembly in vertical arrangement is arranged at one side in the push injection tube body; the regulating assembly comprises an outer sleeve and an inner sleeve arranged in the outer sleeve; the outer sleeve and the inner sleeve are tightly attached; an inner cavity of the inner sleeve is communicated with outside atmosphere; a strip-shaped through opening in vertical arrangement is formed in the inner sleeve; a plurality of small through holes surrounding the outer sleeve for a circle are formed in the outer sleeve at equal gap along the circumferential ring; a height difference exists between every two small through holes; a through hole just for the outer sleeve to pass through is formed in the piston head in the push injection tube body. The suction force is adjustable andcontrollable; the injury on tissues cannot be easily caused; the use safety is high; the suction efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical care, in particular to a miniature negative pressure adjustable drainage device for microscopic hand and foot surgery. Background technique [0002] Negative pressure wound treatment technology is a new technology developed in recent years for the treatment of wounds. It uses bio-semipermeable membranes to seal open wounds, uses a special negative pressure machine to generate a certain negative pressure, and acts on the wound through drainage tubes and dressings. Wound surface after debridement. [0003] At present, in the patent application publication number CN 106267388 A, a special miniature negative pressure adjustable drainage device for hand and foot microsurgery is disclosed, which includes a liquid storage tube and an injection plug, and the injection plug is set inside the liquid storage tube. The liquid storage tube adopts a cylindrical structure with one end open. One end of the liqui...
