Abstract

Revealed a non-reusable syringe with a hollow barrel and a piston that can be moved in the syringe. piston assembly with the piston rod and the piston that are arranged in such a way that limited relative motion relative to each other. The piston rod has a flexible barrier path that can be fitted to the concave part located at Inner wall of the sprayer barrel The protection is arranged detachable in the between the barrel and piston assembly to prevent obstruction piston rod before using the syringe and determine the exact size of the liquid to be injected. Absolutely not repeatable and provides good pre-injection venting. than and faster

Claims (1)

1. Claims (all) which will not appear on the advertisement page. :The reusable syringe does not have a hollow barrel with an open-ended one that is made suitable for receiving subcutaneous needles. and the second open-end that is opposite to the open-end of the first such piston set that moves back and forth in the cylinder; The piston rod consists of Flexible barrier paths that at least have a partial circumference that Usually close to the inner wall of the cylinder, the inner wall is loud. To say the least, there is a concave part, and one has sharp edges. such indentation extending from such an object to one such open end of the barrel; such that it can be fitted with such edges to prevent pulling the piston rod back in the direction of the aforementioned second open end to prevent the piston rod from being pulled back in the direction of the tip. open the aforementioned second end of the barrel beyond the position where the part by Such cycles are worn with such items and the piston set is arranged in such a way that There will be a limited relative motion of the piston rod relative to the piston.
