Abstract
The utility model relates to the field of injectors, in particular to a novel needleless injector capable of consecutively and repeatedly injecting the same liquid medicine. The novel needleless injector comprises an injector body, a front gun tube, an injecting port, a disposable injecting head, a one-way valve, an injecting push rod assembly and a threaded injection syringe, wherein the front gun tube is arranged at the front end of the injector body, the left end of the front gun tube is connected with the right end of the injecting port, the left end of the injecting port is connected with the disposable injecting head, the one-way valve is arranged in the front gun tube, one end of the one-way valve is connected with the injecting port, the other end of the one-way valve is connected with the injecting push rod assembly which is arranged in the front gun tube, and the threaded injection syringe is arranged on the upper portion of the front gun tube. When the needleless injector is used repeatedly, only the disposable injecting head needs replacing. The needleless injector is convenient to operate, does not need disassembling and assembling for feeding of medicine and sterilization, is capable of consecutively injecting the same liquid medicine, and improves working efficiency.
Description
Technical field
This utility model 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 stopping 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, therefore easily form cross infection.
Therefore be necessary the further technological innovation of structure to needleless injector.
The utility model content
The purpose of this utility model is for the defective of prior art and deficiency, 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 adopted in the utility model is:
The needleless injector of a kind of homologous medicinal liquid continuous several times injection described in the utility model, 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, this utility model beneficial effect is: its only needs to change disposable injection head this utility model, 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.

Description of reference numerals:
1, syringe body; 2, front gun barrel; 3, injection port; 4, disposable injection head;
5, check valve; 6, injection putter assembly; 7, screw syringe.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described.
As shown in Figure 1, the needleless injector of a kind of homologous medicinal liquid continuous several times injection described in the utility model, 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 utility model 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 this utility model, 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 better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of this utility model patent claim, feature and principle change or modify, is included in this utility model patent claim.
