Description

Portable accurate ejector
Technical field
This utility model relates to a kind of ejector, particularly relates to a kind of portable accurate ejector.
Background technology
At present, in hospital, there is multiple medical scheme to need past patient's oral cavity, throat, esophagus, medicinal liquid is sprayed at the positions such as stomach, and needing both hands to operate, existing Medical ejector could realize continuous injection when spraying medicinal liquid, can easily the continuous injection medicinal liquid and tolerance spray the dosage of medicinal liquid, and jet length is far away not, projected area is not concentrated, brought inconvenience for the doctor and the patient that need ejector to treat, therefore, need to design and develop a kind of easily continuous injection medicine, it is convenient that tolerance is sprayed liquid dose, and jet length is far away, the portable accurate ejector that projected area is concentrated.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of easily continuous injection medicinal liquid is provided, and it is accurately convenient that tolerance is sprayed liquid dose, and jet length is far away, the portable accurate ejector that projected area is concentrated.
The purpose of this utility model is achieved through the following technical solutions: portable accurate ejector, comprise syringe, container bottle, playpipe and pipette, syringe is comprised of syringe and piston, be connected and fixed playpipe on the unidirectional tapping valve of syringe antetheca, one end of pipette links to each other with the front end side wall of syringe by unidirectional liquid feed valve, the other end of pipette stretches into the container bottle bottom, be provided with spring between piston and the syringe rear wall, on the sidewall of container bottle scale is arranged, the front end of playpipe is provided with nozzle, is fixed with the boundling cover on the nozzle.
The beneficial effects of the utility model are:
1) be provided with spring between piston of the present utility model and the syringe rear wall, the needle handle automatic reduction is drawn to syringe to the origin-location and with medicinal liquid behind the pushing needle handle, and convenient continuously pushing needle handle is with the continuous injection medicinal liquid;
2) on the sidewall of container bottle of the present utility model scale is arranged, make things convenient for precisive to spray the dosage of medicinal liquid;
The front end of playpipe of the present utility model is provided with nozzle, is fixed with the boundling cover on the nozzle, has increased the pressure that sprays medicinal liquid, makes jet length farther, simultaneously, makes projected area more concentrated.
