Abstract
A medical injector belongs to the medical apparatus technical field, comprising a syringe, a push bar, a piston, and a needle head, wherein the median front end of the syringe is provided with a needle head connecting base which is communicated with a syringe inner cavity, the rear end of the piston which is slideably and hermitically connected with the inner wall of the syringe is connected with the push bar, and the front end of the piston is engaged with the inner wall at the front end of the syringe. The utility model is characterized in that the outer wall of the syringe is provided with a ring-shaped finger groove for conveniently clamping the syringe, and the middle portion at the front end of the piston is connected with a section of cylinder whose inner diameter and length are the same as those of the needle head connecting base. The utility mode has the advantages of simple structure, convenient operation, and when injecting, a fore-finger and a middle finger of medical care stuffs are clasped in the finger groove, so they can well exert force, and do not need two hands to operate, thereby the field of vision is widened, the operation is correct, and liquid medicine is not left in the syringe after injecting, so liquid medicine can not be wasted.
Description
Technical field
This utility model belongs to technical field of medical instruments, a kind of specifically injector for medical purpose.
Background technology
The present syringe that uses clinically, its appearance be shiny surface entirely, when a hands is injected in body, points and badly controls, exerts oneself.Usually need the another hands to catch the needle tubing co-operate, such two handss have often blocked medical personnel's oneself the visual field, make operation inaccurate, the influence treatment; And after injection finishes, in the syringe needle Connection Block, usually there is medicinal liquid residual, causes liquid waste.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and when injection syringe is controlled easily, does not have the residual injector for medical purpose of medicinal liquid in the syringe.
The purpose of this utility model is achieved in that this injector for medical purpose is made up of syringe, push rod, piston, syringe needle, syringe front end center is provided with the syringe needle Connection Block that communicates with the syringe inner chamber, the piston rear end that is connected with the slipper seal of syringe inwall is connected with push rod, piston nose matches with the syringe front inner wall, on the outer wall of syringe, be provided with the annular finger groove of being convenient to the clamping syringe, be connected with at piston nose middle part one section with syringe needle Connection Block internal diameter and all identical cylinder of length.
Advantage of the present utility model: simple in structure, easy to operate, when giving patient injection, because medical personnel's forefinger and middle finger are clipped in the finger groove, thus can be good at firmly, need not two hands co-operate, make broad view, operation is accurate, and it is residual to inject the interior no medicinal liquid of back syringe that finishes, and can not cause the waste of medicinal liquid.
Description of drawings
Accompanying drawing is a cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this injector for medical purpose is made up of syringe 1, push rod 2, piston 3, syringe needle 4, syringe 1 front end center is provided with the syringe needle Connection Block 5 that communicates with syringe 1 inner chamber, piston 3 rear ends that are connected with syringe 1 inwall slipper seal are connected with push rod 2, piston 3 front ends match with syringe 1 front inner wall, on the outer wall of syringe 1, be provided with the annular finger groove 6 of being convenient to clamping syringe 1, be connected with one section cylinder 7 all identical with length with syringe needle Connection Block 5 internal diameters in piston 3 front center.
