Abstract

The utility model discloses an injector, the cylinder inner wall sets up the spout, the prismatic constitution of several that the push -and -pull rod is equalled by the interval, the prismatic card that corresponds is in in the spout of cylinder inner wall. When the push -and -pull rod removes the prism freely slides in the spout, is favorable to reducing frictional resistance, makes things convenient for the nurse to draw with the hand push. Cylinder trailing end connection needle handle, the needle handle is the ear shape, and is more a lot of than increase before, convenient exerting oneself. The utility model discloses structural design is ingenious, makes it more be suitable for push -and -pull, laborsaving convenience, handy.

Description

A kind of syringe

[technical field]

This utility model relates to technical field of medical instruments, particularly a kind of syringe.

[background technology]

In test-tube baby therapeutic process, a stage is had to be give progesterone injection injection for curing, this medicine is medicament, general every day is administered once, and mostly takes the mode administration of intragluteal injection, and dosage period is about one month, this oil preparation will be difficult to advance in patient body than other injection in injection process, therefore the nurse being responsible for injecting is due to the long-term bolus syringe of the right hand, cause hand tendon injured, severe patient causes joint deformity.

[utility model content]

In view of this, for overcoming the deficiencies in the prior art, this utility model provides a kind of syringe, is improved structure, makes it be more suitable for push-and-pull, laborsaving convenience.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of syringe, described syringe inwall arranges chute, and described push-pull bar is made up of several prism, and described prism correspondence is stuck in the chute of described syringe inwall.

Preferably, described push-pull bar is made up of the prism that three spacing are equal, and correspondence is stuck in three chutes of described syringe inwall.When push-pull bar moves, described prism is free to slide in chute, is conducive to reducing friction resistance, facilitates nurse to pull.

Further, described syringe tail end connects needle handle, and described needle handle is ear shape, more a lot of than increase before, firmly convenient.

The beneficial effects of the utility model are, reasonable in design, and use palm bolus infusion oil preparation more convenient, it is more suitable for push-and-pull, laborsaving convenience, effective protection injection finger and tendon.

[accompanying drawing explanation]

In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

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

In figure, 1, syringe, 11, chute, 2, push-pull bar, 21, prism, 3, needle handle.

[detailed description of the invention]

Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.

Reference Fig. 1, a kind of syringe, comprise syringe 1 and the push-pull bar 2 being enclosed within syringe 1 inside, push-pull bar 2 is made up of three prisms 21 that spacing is equal, and the tail end of syringe 1 connects needle handle 3, and described needle handle 3 is in ear shape, more a lot of than increase before, conveniently exerts oneself.

Syringe 1 inwall arranges chute 11, and prism 21 correspondence is stuck in chute 11, and when push-pull bar 2 moves, described prism 21 is free to slide in chute 11, is conducive to reducing friction resistance, facilitates nurse to pull.

Further, syringe 1 diameter also increases 2-4cm than before, and needle handle 3 length increases 1-3cm, facilitates palm or finger force.

This utility model reasonable in design, use palm bolus infusion oil preparation more convenient, it is more suitable for push-and-pull, laborsaving convenience, effective protection injection finger and tendon.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
