Abstract
The utility model discloses a postoperative suction drainage device of preauricular flstula. The postoperative suction drainage device of the preauricular flstula comprises a tank body, a drainage tube, a spring, an upper cover and a baseboard. The tank body adopts a blow-organ-type telescopic structure, the upper end cover and the baseboard are arranged at two ends of the tank body and form a sealed cavity body together with the tank body. The spring is arranged inside the sealed cavity, the upper end cover is provided with a cavity body inlet, the drainage tube is connected with the cavity body inlet through a connecting head, and the drainage tube is provided with an adjuster. The postoperative suction drainage device of the preauricular flstula is simple in structure, convenient to use, safe and reliable, strong in practicality, and capable of effectively achieving postoperative drainage of preauricular flstula.
Description
Technical field
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of preauricular fistula postoperative negative pressure drainage device.
Background technology
Preauricular fistula needs drain after excision, and the unspecial utensil for the preauricular fistula postoperative drainage of prior art, most of doctors adopt directly to place drainage strip the art chamber to get final product, owing to there is not container dress drainage-fluid, cause not only insufficient but also contamination of incision of drain, be unfavorable for the rehabilitation of the state of an illness.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, esy to use, safe and reliable, practical, the preauricular fistula postoperative negative pressure drainage device that can effectively realize the preauricular fistula postoperative drainage.
The purpose of this utility model realizes as follows: this drainage device comprises cylindrical shell, drainage tube, spring, upper end cover and base plate, described cylindrical shell adopts the Collapsible structure of blowing organ type, upper end cover and base plate are arranged on the two ends of cylindrical shell and the cavity that cylindrical shell consists of a sealing, spring is arranged in the cavity of cylindrical shell sealing, on the described upper end cover with a cavity entrance, drainage tube is connected with the cavity entrance by joint, on the described drainage tube with actuator.
This utility model can effectively be realized the drain of preauricular fistula postoperative, and drainage-fluid is introduced directly in the cylindrical shell cavity of drainage device, drain very fully, prevent contamination of incision, be conducive to the rehabilitation of the state of an illness.This utility model also has the advantages such as simple in structure, esy to use, safe and reliable, practical.
