The disposable injector comprises a needle cylinder [4] and a piston rod [5], wherein one end of the piston rod [5] is provided with a piston, and the other end of the piston rod [5] is provided with a piston handle [2]. The utility model is characterized in that the piston handle [2] is provided with a finger ring [1]. The utility model has the advantages of simple structure, accurate and reliable back draw, continuous action of the back draw and injection, convenient operation, difficult displacement of needle heads and high work efficiency.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, specifically disposable syringe.
Background technology:
At present, when using syringe to inject, must carry out pumpback as local anesthesia, intramuscular injection.Like this, the one-handed performance inconvenience needs bimanualness sometimes during the pumpback operation; If this moment, another hand-held had an apparatus when carrying out oral cavity partial anesthesia (as), can only one-handed performance, syringe needle instability at this moment, easily displacement, pumpback and action of injection are discontinuous, use inconvenience.
Summary of the invention:
The purpose of this utility model provides a kind of disposable syringe that makes things convenient for one-handed performance to carry out pumpback.
This utility model is to adopt following technical scheme to realize its goal of the invention, a kind of disposable syringe, and it comprises syringe, piston rod, piston rod one end is a piston, the other end is a piston handle, is provided with finger ring on piston handle.
This utility model is pumpback better, is provided with at the end of syringe to refer to holder.
Because adopt technique scheme, this utility model has been realized goal of the invention preferably, it is simple in structure, pumpback accurately and reliably, pumpback forms continuous action with injection, and is easy to operate, syringe needle is difficult for displacement, high efficiency.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By accompanying drawing as can be known, a kind of disposable syringe, it comprises syringe 4, piston rod 5, piston rod 5 one ends are piston, the other end is a piston handle 2, is provided with finger ring 1 on piston handle 2.
This utility model is pumpback better, is provided with at the end of syringe 4 to refer to holder 3.
When this utility model uses, thumb is inserted in finger ring 1, forefinger and middle finger prop up and refer to holder 3, and thumb upwards lifts and is pumpback, is injection downwards.
This utility model can be used for the disposable syringe of specifications such as 2.5ml, 5ml, 10ml, is widely used in the treatment relevant with injection such as local anesthesia, intramuscular injection.
