Description
Technical field
The present invention relates to a kind of syringe.
Background technology
Insulin syringe in the market is divided into two kinds of syringe remaining needle and pen-type injectors.The syringe remaining needle leans on negative pressure to inhale the traditional form of medicine pressurization administration, and the patient need carry out injection at least once every day, so can't guarantee under aseptic condition, to inhale medicine and injection; And present pen-type injector cost is higher, increases patient's financial burden.
Summary of the invention
The purpose of this invention is to provide a kind of two insulin special syringe that quantizes, higher and can't guarantee the problem of aseptic injection to solve present insulin syringe cost.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: said syringe comprises tubular type bottle, piston, piston augering screw, adjusting quantifying ring, hat type push head and the needle cap that insulin is housed; The bottle that the tubular type bottle of insulin is housed is marked with scale; Head end and needle cap that the tubular type bottle of insulin is housed removably connect; Syringe needle hole on the needle cap with insulin tubular type bottle be housed be communicated with, an end of piston augering screw is connected with piston thread, the other end of piston augering screw and hat type push head removably connect; Piston and piston augering screw one end all are contained in the tubular type bottle that insulin is housed; And piston and the tubular type bottle that insulin is housed are slidingly connected, and regulate quantifying ring and are located at the outside of tubular type bottle that insulin is housed and regulate quantifying ring and be threaded with the piston augering screw, and the outer wall of piston augering screw is provided with many component lines vertically; Many component lines are along the circumferencial direction uniform distribution of piston augering screw;
Pitch P=the 2mL/n of piston augering screw; L is the space axial length that the tubular type bottle storage insulin of insulin is housed; N is the quantity that the iu of the insulin of storing in the tubular type bottle of insulin is housed; M is the quantity of component lines, regulates quantifying ring and equates with the pitch that the piston augering screw matches.
The present invention has following beneficial effect: manufacturing process of the present invention is simple, with low cost; Easy to use; The component lines of piston augering screw is marked with graduated pair of quantizing structure with the bottle that the tubular type bottle of insulin is housed makes metering method more accurate; The financial burden of having avoided the great number expenses for medicine to bring for the patient, it is simple to change syringe needle, has satisfied the requirement of aseptic injection.
