Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and a kind of specifically department of pediatrics simple in structure is used the negative pressure aspirator.
Background technology
At present, often need use aspirator, especially department of pediatrics in the hospital clinical nursery work; Pediatric patient often has feces residue or urine residue on one's body, generally all is to siphon away with aspirator, when in the pediatric patient mouth expectorant being arranged sometimes; Also inhale, but the aspirator of prior art generally all is to have that price is high, volume is heavy, carry inconvenient deficiency that the loaded down with trivial details trouble of use, negative pressure are bigger with aspirator; Wayward; Be not easy to medical worker's nursery work, cost higher and its repeatedly usability cause cross infection easily, increased patient's medical treatment cost.
Summary of the invention
The technical assignment of this utility model is the deficiency that solves prior art, provides a kind of department of pediatrics simple in structure, easy to use to use the negative pressure aspirator.
The technical scheme of this utility model realizes that by following mode this department of pediatrics is used the negative pressure aspirator, and its structure comprises that an end is installed in the suction pipe on the connection cover; The other end of suction pipe has suction nozzle; Said connection cover is threaded in the liquid storage cylinder, and the front portion of said liquid storage cylinder has slideway, and the slideway front side is provided with unidirectional exhaust-valve; Slidely connect the front end that pushes away body in the slideway; The rear end that pushes away body connects the liquid storage cylinder bottom through spring, and the described body that pushes away also is connected with brace through pivot pin, and brace is arranged on an end of hand-held folder and in the chute that liquid storage cylinder is opened, slides.
Described hand-held folder is " U " shape and its other end is fixed on the liquid storage cylinder.
The said body front end that pushes away is provided with an annular projection, and this annular projection closely contacts in the slideway of liquid storage cylinder.
Said suction pipe front portion is provided with a taper protective cover.
The emptying outside liquid storage cylinder of described unidirectional exhaust-valve.
The beneficial effect that this utility model is compared with prior art produced is:
The department of pediatrics of this utility model has simple in structure, reasonable in design, characteristics such as be skillfully constructed with the negative pressure aspirator, and its structure is small and exquisite and be easy to carry about with one, and each parts convenient disassembly; Simple to operate, only need hold hand-held folder and can realize negative pressure, promote the carrying out of imbibition nursery work; Be provided with protective cover in the suction pipe front side; Avoid suction pipe being stung bad situation, can effectively improve nursing staff's work efficiency because of the pediatric patients excitement, time saving and energy saving.
