Example Embodiment

[0015] The present invention will be further described in detail below through specific implementations:

[0016] The reference signs in the drawings of the specification include: puncture guide needle 1, handle 2, first drainage tube 3, drainage hole 4, cover 5, syringe body 6, piston rod 7, support column 8, bayonet 9, and The second drainage tube 10, the clip 11, the engaging portion 12, the pressing portion 13, the protrusion 14, the drug delivery tube 15, the drug delivery branch tube 16, the heparin cap 17, and the baffle 18.

[0017] The embodiment is basically as attached figure 1 And figure 2 Shown: A device for continuous negative pressure drainage of pus in the body includes a puncture guide needle 1. The upper end of the puncture guide needle 1 is covered with a handle 2 located outside the first drainage tube 3, and the handle 2 facilitates the puncture operation. The diameter of the puncture guide needle 1 gradually increases from bottom to top, and the wound surface...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a continuous negative pressure drainage device for pus in the body. Background technique [0002] Clinically, the treatment plan for soft tissue abscess in the body is effective drainage, but at present, surgical incision and drainage or repeated puncture and aspiration are often used clinically; surgical incision and drainage have large surgical trauma and require a long time after surgery The pain during dressing change, postoperative scar and other problems are gradually unacceptable; although repeated puncture and drainage can avoid the pain of dressing change and postoperative scar, it still needs repeated ultrasound Guided puncture operation, drainage of pus in batches, has problems such as long treatment time, inconvenient flushing, and poor drainage effect, especially for breast-feeding breast abscess patients, which affects breastfeeding to a certain extent, caus...
