Abstract
The utility model relates to a hydrothorax drainage apparatus and belongs to the technical field of medical equipment. The hydrothorax drainage apparatus comprises an indwelling drainage tube, a negative pressure device and a sterile drainage bag, wherein the indwelling drainage tube is connected with the negative pressure device and the sterile drainage bag through a tee joint; an air guide tube is connected between the negative pressure device and the tee joint; a pressure regulating device is arranged on the air guide tube; the tee joint is connected with the indwelling drainage tube through a drainage tube. The hydrothorax drainage apparatus is characterized in that an expanded tube is arranged at the front part of the drainage tube; the drainage tube is in plug-in fit in the expanded tube; the diameter of the expanded tube is 5-10 times as that of the drainage pipe. The hydrothorax drainage apparatus is simple in structure and low in price, can prevent returning of hydrothorax in the drainage tube after drainage, and has a good drainage effect.
Description
Technical field
This utility model relates to a kind of internal medicine medical apparatus and instruments, specifically a kind of drainage device.
Background technology
Hydrothorax is the modal performance of pleural diseases, is a kind of common clinical disease.Malignant pleural effusion, be prone to uncomfortable in chest, breathe hard and the malaise symptoms such as dyspnea, the state of an illness can increase the weight of rapidly in the short time, prognosis is poor.At present, adopt behind B ultrasonic or CT location clinically more, intrathoracic enters central venous catheter, uses negative pressure drainage device drain.
The problem that prior art drainage device exists is mainly: 1) drainage effect is not good, needs often to adjust drain position; 2) drain is complete, and under negative pressure exists, the hydrops in conduit returns to thoracic cavity.Return to problem for solving hydrops, the anti-film that backflows is generally set in mozzle, at present, the anti-film that backflows is external import, expensive, has increased patient's burden.
Summary of the invention
This utility model provides a kind of drainage device, its simple in structure, low price, and complete in drain, can prevent that in drainage tube, hydrops returns, drainage effect is good.
The concrete technical scheme adopting of this utility model is:
A kind of drainage device, comprise indwelling drainage tube, negative pressure device, aseptic drainage bag, indwelling drainage tube is connected by threeway with negative pressure device, aseptic drainage bag, wherein between negative pressure device and threeway, be connected airway, regulator is set on airway, between threeway and indwelling drainage tube, be connected by drainage tube, it is characterized in that, front portion at mozzle arranges expander, the drainage tube cooperation of pegging graft in expander, and the 5-10 that the diameter of described expander is drainage tube is doubly.
Further, for preventing that in-vivo tissue from stopping, stopping up, hydrops is discharged smoothly, this utility model is taper type in the front portion of indwelling drainage tube, which is provided with side opening, is also provided with spherical drainage head at the front end of drainage tube.
For fixed diversion pipe, avoid gravity tractive, be provided with fixture at the rear portion of mozzle, described fixture is medical proof fabric, suture needle etc.
This utility model is in the time of drainage procedure, and drainage tube is plugged in together in expander, and drain finishes, and medical personnel are manual to be disconnected drainage tube in expander, discharges negative pressure, and the residual liquid in drainage tube can not return to thoracic cavity.
Another advantage of this utility model is, owing to having set up spherical drainage head, avoids in-vivo tissue to stop up, and drainage effect is good.
