Abstract
The utility model discloses a novel injector, comprising a work drum and a push-and-pull rod which is arranged in the work drum, the side wall of the work drum is provided with a support bar, and the end portion of the support bar is provided with a guide and push plane. The utility model has the advantages that the structure is simple, can be operated by single hand, the force is small and balanced, the needle will not shake, thereby avoiding stabbing vascular walls, and greatly reducing pain of a patient.
Description
Technical field
This utility model relates to a kind of medical apparatus, relates in particular to a kind of novel syringe.
Background technology
At present, general hospital is the widespread usage disposable sterilized injector, carries out clinical injection and blood sample collection, and the problem of cross infection has effectively been avoided in the use of disposable sterilized injector.But during the imbibition before blood drawing when taking a blood sample or the injection, often need with the hands to operate, promptly one hold syringe, another hand operated push-pull bar, especially when blood drawing, blood vessel is not obvious, and medical personnel then can't be in the pulling push-pull bar, make to keep certain negative pressure in the syringe, remove to touch skin searching blood vessel and vacate a hands; And in the blood drawing process on syringe and the push-pull bar two impetus away from, firmly big, be difficult to keep in balance, the feasible syringe needle meeting slight jitter of having inserted blood vessel, stab blood vessel wall easily, the misery that adds the heavy patient, also might make penetrate blood vessel syringe needle in the blood drawing process shake and deviate from blood vessel, and then increased the operation of medical workers difficulty.If one-handed performance, it is bigger to finish the said procedure difficulty.
The utility model content
The purpose of this utility model in order to overcome above-mentioned deficiency of the prior art, provides a kind of rational in infrastructure, one-hand operation just, firmly little, and firmly balanced, syringe needle can not produce shake, avoid stabbing blood vessel wall, can reduce a kind of novel injector of patient's misery greatly.
This utility model is achieved by following technical proposals: a kind of novel injector, and comprise syringe and be arranged on the interior push-pull bar of syringe, the sidewall of described syringe is provided with support bar, and the end of described support bar is provided with to lead and pushes away plane body.
The sidewall of described support bar and syringe is for fixedlying connected.
The length of described support bar is less than the length of push-pull bar.
Described support bar is that T shape, semicircle, circle, ellipse, four rhombuses or triangular structure constitute.
Another technical scheme of the present utility model is: a kind of novel injector, comprise syringe and be arranged on the interior push-pull bar of syringe, the sidewall of described syringe is provided with the grafting groove, is provided with support bar in the described grafting groove, and the end of described support bar is provided with to lead and pushes away plane body.
The groove width of described grafting groove and the diameter of support bar are complementary.
The length of described support bar is less than the length of push-pull bar.
Described support bar is that T shape, semicircle, circle, ellipse, four rhombuses or triangular structure constitute.
The beneficial effects of the utility model are:
1. owing to the sidewall at syringe is provided with support bar, make support bar and push-pull bar to interact, when extracting liquid, form an anti-power that pushes away support bar, and avoided the action of drawing, two impetus are moved closer to, on the basis of not losing original function, thereby realize one-handed performance, make the firmly more balanced of hands, make operation more reasonable, easy.
2. this utility model cost is low, is easy to produce.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
As shown in Figure 1, a kind of novel injector of this utility model comprises syringe 1 and the push-pull bar 2 that is arranged in the syringe 1, and the sidewall of described syringe 1 is provided with support bar 3, and the length of its support bar 3 is less than more than the about 3mm of length of push-pull bar 2; In order to strengthen the hardness of support bar 3, its structure can adopt T shape, semicircle, circle, ellipse, four rhombuses or triangular structure to constitute, and described support bar 3 can also can be to flexibly connect for fixedlying connected with the sidewall of syringe 1; When adopting when fixedly connected, only need support bar 3 thermosettings get final product at the sidewall of syringe 1, certainly, when the production needle tubing, mould is prepared into the mould that has support bar 3, but single injection-molded then; In order to reduce the volume of syringe, be convenient to packing, also support bar 3 and syringe 1 can be adopted the mode that flexibly connects, promptly can be for the grafting groove 5 (as shown in Figure 2) of grafting support bar 3 in the sidewall thermosetting or one of the injection moulding of syringe 1, the position, upper end that present embodiment grafting groove 5 is arranged on syringe 1 is schematically, can also be arranged on the diverse location of syringe sidepiece upper, middle and lower; The diameter of the groove width of described grafting groove 5 and support bar 3 is complementary, and when using, support bar 3 is inserted groove 5 interior getting final product; The end of described support bar 3 is provided with one and leads and push away plane body 4, leading and pushing away plane body 4 is when being used for pull push-pull bar 2, the operator acts on a propulsive thrust (as shown in Figure 3) on its plane body 4, like this, the equilibrium of having exerted oneself when having guaranteed to extract liquid makes operation more stable, especially the syringe needle generation of having avoided thrusting blood vessel is rocked, stab the slippage of blood vessel wall or syringe needle, reduced patient's misery, and then also can finish the purpose of one-handed performance syringe.
It is described when support bar and syringe adopt the mode that flexibly connects, support bar can be made of plastics, and also can be made by metal material or other materials, as long as the operator holds a support bar, the needle tubing that just can be combined with the grafting groove carries out use repeatedly repeatedly, saves cost with this.
