FIELD OF INVENTION
This invention relates to an auto-disable syringe for single use.
PRIOR ART
Currently available disposable syringe(s) can be re-used 8B miss-used. This causes harmful effects not only to the patients but also to the healthcare workers. Hence, an improved single use syringe is required to be introduced.
OBJECTS OF THE INVENTION
The primary object of the present invention is to provide an auto-disable single use syringe which overcomes disadvantages associated with the prior art.
Another object of the present invention is to provide an auto-disable syringe which is simple in construction.
Further object of the present invention is to provide an auto-disable syringe which is efficient.)
STATEMENT OF INVENTION
According to this invention, there is provided an auto-disable syringe comprising of a plunger having a pointed tip with a gasket there below in a barrel to be incorporated inside barrel luer ( nozzle) after use.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS:-
Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein:
Fig. 1 shows: front view of the present invention.
Fig. 2 shows: enlarged view of top part of the present invention.
Fig. 3 shows: ring inside barrel luer (nozzle).
DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS: -
The present invention discloses an auto disable syringe as shown in the
accompanying figures wherein a plunger (1) with an arrow like profile (2)
at its tip is provided for getting the same locked by means of a ring (as
shown in fig. 3) locked at the entry point of luer (nozzle) of barrel (4) after
use. Further, as an additional safety, a hinge (5) is provided at the lower
portion of plunger (as shown in fig.l). So that, after use the bottom
portion of said plunger can be detached to keep the plunger inside the
barrel. This again avoids re-use of the syringe.
The auto-disable syringe of the present invention is based on a mechanism such that after single administration of medicament, it can never be re-used. After administration of prescribed dose, its plunger with pointed tip below which an 'O' ring designed gasket (3) is provided is incorporated inside the barrel luer (nozzle) for getting the same locked. Its
barrel luer (nozzle) has ring inside, which prevents the pointed tip of plunger to move backward. Once plunger is locked, its lower extended part is being bent to be broken.
It is to be understood that the above-described embodiments are illustrative of only a few of the many possible specific embodiments, which can represent applications of the principles of the invention. However, numerous and varied other arrangements can be readily devised in accordance with these principles by those skilled in the art without departing from the spirit and scope of the invention.

WE CLAIM:
1. An auto-disable syringe comprising of a plunger having a pointed tip with a gasket there below in a barrel to be incorporated inside barrel luer (nozzle) after use.
2. An auto-disable syringe as claimed in claim 1, wherein said barrel luer (nozzle) is provided with a ring there within.
3. An auto-disable syringe as claimed in claim 1 or 2, wherein said plunger is provided with a hinge at its lower part.
4. An auto-disable syringe substantially as herein described with reference to the accompanying drawings.
