Abstract
A continuous quantitative syringe for diabetic belongs to the medical instrument technology field. The syringe comprises a syringe needle, a syringe cylinder, a piston, a needle bolt and a fixing cover; the syringe needle is sleeved to the front end of the syringe cylinder, the fixing cover is in threaded connection to the rear end; the needle bolt is connected with the piston in the syringe cylinder through the through hole on the center of the fixing cover. The syringe characterized in that: a plurality of limiting pins with uniform spaces and mutually perpendicular axes are disposed on the needle bolt; and two notches for passing the limiting pins are symmetrically formed on the edge of the through hole on the center of the fixing cover. The advantages of the utility model lies in: simple structure, low cost, convenient for carrying out; and can be continuously used by the patient himself, can control injection capacity accurately, and can reduce expenditure for patient.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of diabetes patient's continuous and quantitative syringe.
Background technology
Raising along with China's living standards of the people, onset diabetes improves year by year, often pass through long term injections islets of langerhans disease controlling usually for diabetics at present, the diabetes patient will inject repeatedly every day, all to from medicine bottle, extract medicinal liquid at every turn, inject behind the routine disinfection, program is comparatively complicated, is restricted when particularly going out again.And the insulin injection pen that uses now costs an arm and a leg; Use disposable syringe, easily cause bigger waste again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, and cost is low, diabetes patient's continuous and quantitative syringe that can use voluntarily continuously.
The purpose of this utility model is achieved in that this diabetes patient's continuous and quantitative syringe is made up of syringe needle, syringe, piston, pintle, fixed cap, the syringe front end is with syringe needle, the rear end fixed cap that is being threaded, pintle pass the intermediary through hole of fixed cap and link to each other with piston in the syringe; On pintle, be provided with the orthogonal spacer pin of a plurality of evenly spaced axis, symmetricly on the intermediary through hole of the fixed cap limit be provided with two breach that spacer pin is passed through.
During injection, make above the pintle near the spacer pin of indentation, there relatively, promote pintle forward, when the spacer pin arrival fixed cap of rear adjacent, can finish a calibrated shot with breach above the through hole; When reusing, pintle is rotated in syringe needle sterilization back make near the spacer pin at fixed cap place and can inject after relative with breach above the through hole, so repeatedly, till injecting liquid drug finishes.
Advantage of the present utility model: simple in structure, cost is low, can use voluntarily continuously, and the injection volume precise control is convenient to go out to carry, and can reduce patient's expense.
