The invention patent discloses an
in vivo pus continuous negative pressure drainage device, in particular to the technical field of medical apparatus. The
in vivo pus continuous negative pressure drainage device comprises a
puncturing guide needle, wherein a drainage groove is formed in the
puncturing guide needle; a drainage tube is arranged outside the
puncturing guide needle; a plurality of drainage holes are formed in the same positions of the puncturing guide needle and the drainage tube, and are close to a puncturing part on the puncturing guide needle; a cover body covers one end away from the drainage holes, of the drainage tube, and is used for sealing the end of the drainage tube; and a negative pressure mechanism also communicates with one end close to the cover body, of the drainage tube, and can enable constant negative pressure to produce in the drainage tube. Through the adoption of the
in vivo pus continuous negative pressure drainage device disclosed by the invention,the problems that in the incision and drainage of a conventional
abscess surgical operation, the operation wound is large, pains generated during postoperative
medicine exchanging exist, postoperativeblemish exists, and in repeated puncturing suction, drainage in batches is needed, the
treatment time is long, rinsing is inconvenient, and drainage effect is poor are overcome, and the in vivo pus continuous negative pressure drainage device can be used for continuously extracting pus in the body of a patient.
