Medical puncture drainage apparatus

Abstract

The invention discloses a medical puncture drainage apparatus, which comprises a drainage hose, an inner tube and an outer tube, wherein the outer tube is sheathed on the inner tube, and the tail end of the inner tube and the drainage hose are in sealing connection. The medical puncture drainage apparatus also comprises a pushing device; the outer tube is provided with a head end fixing part, a tail end sliding part and a middle section deformation part capable of being radially enlarged, wherein the head end fixing part is fixedly connected with the inner tube; the tail end sliding part and the middle section deformation part can slide relative to the inner tube; the pushing device is installed in the tail part of the inner tube and is fixedly connected with the outer tube to bring convenience for the pushing device to push the tail end sliding part and the middle section deformation part to slide relative to the inner tube; the radial size of the middle section deformation part is enlarged; and therefore the middle section deformation part is clamped and fixed on the human tissue. According to the medical puncture drainage apparatus disclosed by the invention, the outer tube can be firmly clamped and fixed on the human tissue, and the phenomena of shifting and falling in the drainage process as well as incision infection caused by mutual friction because of infirm fixing and connection can be avoided.

Description

technical field [0001] The invention relates to a medical puncture drainage device, which belongs to the technical field of medical instruments. Background technique [0002] At present, with the popularization and application of interventional devices, their advantages such as small wounds, light pain, quick recovery, and low risk have been well received by doctors and patients. In the past, puncture drainage was to insert the drainage catheter directly into the lesion for negative pressure drainage. Since there is no good stable fixing device between the tube and the incision, catheter displacement, falling off, and friction between the fixed connection and the incision infection often occur. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a medical puncture drainage device, which can make the outer tube firmly stuck on the human tissue, avoiding displacement, falli...
