Abstract
The invention relates to the field of injectors, particularly to a novel needleless injector capable of continuously and repeatedly injecting the same liquid medicine. The needleless injector comprises an injector body, a front barrel, an injection port, a disposable injection head, a check valve, an injection pushrod assembly and a screw injector, wherein the front barrel is arranged at the front end of the injector body; the left end of the front barrel is connected with the right end of the injection port; the left end of the injection port is connected with the disposable injection head; the check valve is arranged in the front barrel, one end is connected with the injection port, and the other end is connected with the injection pushrod assembly arranged in the front barrel; and the screw injector is arranged on the upper portion of the front barrel. According to the needleless injector, only the disposable injection head is needed to replace, the operation is simple, assembly and disassembly for medicine liquid re-supply and disinfection are not needed, continuous injection can be achieved for the same liquid medicine, and the working efficiency is improved.
Description
Technical field
The present invention relates to syringe art, particularly a kind of needleless injector of homologous medicinal liquid continuous several times injection.
Background technology
Along with the development of injection technique, also great changes have taken place for injecting apparatus.Turned to needleless injector from traditional needle applicator that has, now there is following problem in the normal needleless injector that uses: for the continuous injector of many person-times of injection same medicinal liquids the time, owing to otherwise stop again dismounting administration and inefficiency is wasted time and energy in sterilization.Syringe does not arrange check valve at injection port now in addition, thereby is prone to the medicinal liquid backflow in injection, so easily form cross infection.
So be necessary the further technological innovation of structure to needleless injector.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, provide a kind of simple in structure, the needleless injector of a kind of homologous medicinal liquid continuous several times injection reasonable in design, easy to use, it only needs to change disposable injection head, it have easy to operate, do not need dismounting again administration and sterilization, improved work efficiency.
For achieving the above object, the technical solution used in the present invention is:
The needleless injector of a kind of homologous medicinal liquid continuous several times injection of the present invention, comprise syringe body, front gun barrel, injection port, disposable injection head, check valve, injection putter assembly and screw syringe, described syringe body front end arranges front gun barrel; Described front gun barrel left end links to each other with the injection port right-hand member; Described injection port left end links to each other with disposable injection head; Described check valve is arranged in the front gun barrel, and an end links to each other with injection port; The other end links to each other with the injection putter assembly; Described injection putter assembly is arranged in the front gun barrel; Described screw syringe is arranged on front gun barrel top.
After adopting said structure, beneficial effect of the present invention is: its only needs to change disposable injection head the present invention, it have easy to operate, do not need dismounting again administration and sterilization, can inject continuously for medicinal liquid of the same race, improved work efficiency.

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the needleless injector of a kind of homologous medicinal liquid continuous several times injection of the present invention, comprise syringe body 1, front gun barrel 2, injection port 3, disposable injection head 4, check valve 5, injection putter assembly 6 and screw syringe 7, described syringe body 1 front end arranges front gun barrel 2; Described front gun barrel 2 left ends link to each other with injection port 3 right-hand members; Described injection port 3 left ends link to each other with disposable injection head 4; Described check valve 5 is arranged in the front gun barrel 2, and an end links to each other with injection port 3; The other end links to each other with injection putter assembly 6; Described injection putter assembly 6 is arranged in the front gun barrel; Described screw syringe 7 is arranged on front gun barrel top.
Operation principle of the present invention is as follows: when carrying out multiple injection for medicinal liquid of the same race, medicinal liquid is stored in the screw syringe 7, utilize injection putter assembly 6,4 couples of patients of disposable injection head by injection port 3 front ends carry out injecting liquid drug, as long as change disposable injection head 4, can inject next patient, injectable was about 100 times in average 30 minutes, speed is fast, high efficiency.
Its only needs to change disposable injection head the present invention, it have easy to operate, do not need dismounting again administration and sterilization, can inject continuously for medicinal liquid of the same race, improved work efficiency.
The above only is preferred embodiments of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
