Abstract

The utility model discloses a sputum aspirator and relates to the field of medical instrument. The sputum aspirator comprises an injection tube (1), a straw (2) and an air outlet tube (3). The injection tube (1) is connected to the straw (2). A piston (4) and a core pin (5) are arranged inside a cavity of the injection tube and are integrated. The air outlet tube (3) is arranged at the front end of the injection (1). A one-way inhalation valve (6) is arranged on the straw (2). A one-way air outlet valve (7) is arranged on the air outlet tube (3). The sputum aspirator can overcome the defects of the existing technology. Since an air bladder is replaced with the injection tube with great suction capacity, the air outlet tube is added on the injection tube, the one-way air outlet valve is added on the air outlet tube and the one-way inhalation valve is added on the straw, so that convenience in operation and practical applicability are improved.

Description

A kind of sputum aspirator

Technical field

This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of sputum aspirator.

Background technology

For the critical patient, because unable cough, sputum very easily blocks respiratory tract and threat to life safety, and therefore, in time cleaning alluvial sputum is as early as possible one of the important channel of Survive the perils of life of patient.But clinical used sputum aspirator mostly is greatly unified negative pressure system at present, and the position is fixed, or is DYN dynamic, and is relatively heavier, mobile inconvenience, and many patients often can not get removing timely owing to the sputum of alluvial, and have incured loss through delay best rescue time.

At present, occurred many Portable sputum aspirators on the market, it mainly comprises air bag, suction pipe, phlegm storage device, it is simple in structure, easy to make, be easy to carry flexible operation, but the suction of air bag is inadequate, and the phlegm storage device that arranges of existing sputum aspirator, also had a strong impact on the suction of sputum aspirator, when the sputum that runs into than thickness, air bag just loses its effect, has delayed rescue time.

Summary of the invention

The purpose of this utility model provides a kind of sputum aspirator, it can overcome the drawback of prior art, air bag is replaced to the larger syringe of suction, also set up escape pipe at syringe in addition, set up unidirectional air outlet valve at escape pipe, set up breather cheek valve at suction pipe, core bar in the pulling syringe, just can be by suction pipe with the expectorant sucking-off, this moment, the escape pipe cut-off promoted core bar, can will be inhaled into the intraluminal sputum of syringe discharges through escape pipe, suction pipe cut-off this moment is used more conveniently, and practicality is stronger.

In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises syringe 1, suction pipe 2 and escape pipe 3, syringe 1 is connected with suction pipe 2, be provided with piston 4 and core bar 5 in syringe 1 interior lumen, and piston 4 is one-body molded with core bar 5, and escape pipe 3 is arranged on the front end of syringe 1.

Be provided with one-way sucting valve 6 on the described suction pipe 2.

Be provided with unidirectional air outlet valve 7 on the described escape pipe 3.

This utility model in use, suction pipe 2 is probeed into afterwards depths of patient, core bar 5 in the pulling syringe 1, just can be by suction pipe 2 with the expectorant sucking-off, this moment, escape pipe 3 was owing to the effect of unidirectional air outlet valve 7 ends, promote core bar 5, can will be inhaled into syringe 1 intraluminal sputum and discharge through escape pipe 3, this moment, suction pipe 2 was because the effect cut-off of breather cheek valve 6.

This utility model can overcome the drawback of prior art, and air bag is replaced to the larger syringe of suction, also sets up escape pipe at syringe in addition, set up unidirectional air outlet valve at escape pipe, set up breather cheek valve at suction pipe, used more conveniently, practicality is stronger.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Referring to Fig. 1, this specific embodiment is by the following technical solutions: it comprises syringe 1, suction pipe 2 and escape pipe 3, and syringe 1 is connected with suction pipe 2, is provided with piston 4 and core bar 5 in syringe 1 interior lumen, and piston 4 is one-body molded with core bar 5, and escape pipe 3 is arranged on the front end of syringe 1.

Be provided with one-way sucting valve 6 on the described suction pipe 2.

This specific embodiment in use, suction pipe 2 is probeed into afterwards depths of patient, core bar 5 in the pulling syringe 1, just can be by suction pipe 2 with the expectorant sucking-off, this moment, escape pipe 3 was owing to the effect of unidirectional air outlet valve 7 ends, promote core bar 5, can will be inhaled into syringe 1 intraluminal sputum and discharge through escape pipe 3, this moment, suction pipe 2 was because the effect cut-off of breather cheek valve 6.

This specific embodiment can overcome the drawback of prior art, and air bag is replaced to the larger syringe of suction, also sets up escape pipe at syringe in addition, set up unidirectional air outlet valve at escape pipe, set up breather cheek valve at suction pipe, used more conveniently, practicality is stronger.
