CN203417373U - Injector with booster - Google Patents

Abstract

The utility model discloses an injector with a booster. The injector comprises a mandrel, an outer sleeve and a piston, wherein the booster is arranged at the top of the outer sleeve and is a triangular wedge block, transverse fluctuation lines are arranged on the booster, and a central line is consistent to the central line of the turned edge of the outer sleeve. When the injector is used, an ampoule is clamped with the index finger and the middle finger of the left hand, meanwhile the lower end of a needle cylinder is fixed with the thumb, the ring finger and the little finger, the thumb is put on the booster, the mandrel is pulled with the right hand, liquid medicine is pumped into the needle cylinder of the injector. The injector with the booster has the advantages of being simple in structure, difficult to slip off during operation and reliable in effect.

Description

Be with assisted syringe

Technical field

This utility model relates to medical apparatus field, is specifically related to a kind of assisted syringe of being with.

Background technology

The syringe using mostly at present is the disposable syringe that plastics are manufactured, and the danger of infecting occurs while greatly reducing injection.Syringe often connects together with injection needle, for by liquid or gas inject to bodily tissue or therefrom extraction.When using syringe extracting liquid, need to pinch syringe jacket with a hands, the push rod that another pulls moving syringe fills liquid to syringe cylinder.The syringe of existing syringe is smooth cylindrical, and when extracting liquid, complete armrest pinches overcoat and operates, easily because of the reasons such as hands is wet and slippery cause landing or operation unstable.And existing syringe in actual use, nurse might not operate according to actual operating specification, often adopts one-handed performance, causes hand to contact with syringe core rod, in the moving back and forth of core bar, likely causes liquid medicine contamination.

Utility model content

The technical problems to be solved in the utility model, provide a kind of simple and reasonable, good reliability, syringe easy to use, to solve the problem that in prior art, syringe in use aspirates hands and syringe jacket easily slides, comes off, can make nurse standardized operation simultaneously.

The technical solution of the utility model is: be a kind ofly with assisted syringe to comprise core bar, overcoat, piston, also comprise that booster, booster are arranged on overcoat top, are the wedge of del.

As a kind of preferred structure, horizontal heave line can be set on booster, its centrage is consistent with the crimping centrage of overcoat.

The beneficial effects of the utility model are, increase booster at overcoat top, and when actual aspiration medicinal liquid, left index finger, middle finger are clamped ampoule, and with the fixing syringe lower end of thumb, the third finger, little finger of toe, the right hand pulls core bar, and medicinal liquid is evacuated in syringe sleeve simultaneously.The advantage of this utility model syringe: 1, simple in structure, on existing disposable syringe, improve, do not change its original mode of operation; While 2, taking out liquid draw, left hand thumb has stress point clearly, is convenient to imbibition, can not be subject to the wet and slippery impact of hand to cause the operation of error; 3, standard nurse operation rules, have booster device to be convenient to nurse according to working specification unified operation.

Accompanying drawing explanation

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

Fig. 2 is the side view of Fig. 1.

The label of Fig. 1 is: 1, core bar; 2, overcoat; 3, piston; 4, booster; 41 heave lines.

The specific embodiment

As can be seen from Figure 1 syringe of the present utility model, comprising: core bar 1, overcoat 2, piston 3, at overcoat 2 tops, be provided with booster 4, and booster is the wedge of del.On booster 4, be provided with horizontal heave line 41 as shown in Figure 2, its centrage is consistent with the crimping centrage of overcoat 2.The frictional force that heave line 41 can increase 4 of thumb and boosters is set on booster 4, and assist is more reliable.

During use, left index finger, middle finger are clamped ampoule, use fixedly syringe lower end of thumb, the third finger, little finger of toe simultaneously, and thumb is placed on booster 4, and the right hand pulls core bar 1, and medicinal liquid is evacuated in injector syringe.

Claims (2)

1. be with an assisted syringe, comprise core bar, overcoat, piston, it is characterized in that, also comprise that booster, booster are arranged on overcoat top, are the wedge of del.

2. syringe according to claim 1, is characterized in that, horizontal heave line is set on booster, and its centrage is consistent with the crimping centrage of overcoat.
