Abstract
The utility model discloses a hand-operated negative-pressure suction apparatus which comprises a tank body; a cover body is arranged at the upper part of the tank body; a thread buckle is arranged in the central position of the cover body; a thread rod is arranged in the thread buckle in a sleeve joint manner; a piston is arranged at the bottom end of the thread rod; a rotary disc is arranged at the top end of the thread rod; and the position of the tank body, which is close to the bottom, is communicated with an air inlet pipe. During operation, the air inlet pipe is sleeved by a pipe, the rotary disc is rotated, and the thread rod drives the piston to rotate, so that a negative pressure is formed. When being adopted to carry out negative-pressure suction, the hand-operated negative-pressure suction apparatus with a simple structure is convenient to use and position during rotation, brings convenience for medical work, and has a large negative-pressure suction pressure.
Description
Technical field
This utility model relates to medical apparatus and instruments, relates to a kind of manual negative pressure aspirator specifically.
Background technology
In the orthopaedic surgical operations operation, a lot of surgical patients need the otch drain, and need carry out negative pressure drainage; Conventional vacuum extractor is plastic sheeting, and the centre accompanies turn; Lean on the strength of spring to keep negative pressure; Require little can satisfying with pressure, but require the greater to be difficult to satisfy pressure, and gas leakage easily.
Summary of the invention
The problem that this utility model will solve provides a kind of manual negative pressure aspirator easily, and this manual negative pressure aspirator can carry out vacuum suction easily.
In order to address the above problem, this utility model adopts following technical scheme:
A kind of manual negative pressure aspirator comprises tank body, and the top of said tank body is provided with lid, and said lid center position is provided with screw buckle, is socketed with threaded rod in the said screw buckle, and the bottom of said threaded rod is provided with piston, and the top of said threaded rod is provided with rotation disc; Said tank body is communicated with air inlet pipe near the position of bottom.
Below be further improvement to technique scheme:
Said lid is threaded with tank body.
Said lid is provided with the gas outlet.
During work, cover connects pipe on air inlet pipe, the rotation rotation disc, and threaded rod drives piston rotation; Form negative pressure, adopt this utility model to carry out vacuum suction, simple in structure, easy to use; Facility has been brought to curative activity in convenient location during rotation, and vacuum suction pressure is big.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described further.
