subject: Medical Needle And Syinge We Supply [print this page] A medical syringe manufacturers comprising: an outer housing having forward and rear end portions, a syringe manufacturers barrel of curvilinear cross-section slidable in the outer housing, a resilient seal in a forward portion of the outer housing, a hollow needle extending forwardly from the syringe manufacturers barrel and movable therewith to penetrate the seal member and extend outwardly from the forward end of the outer housing, spring means between the syringe manufacturers barrel and a forward wall portion of the housing, means to apply pressure on liquid in the syringe manufacturers barrel and to apply partial vacuum thereto for selective movement of the syringe manufacturers barrel to compress the spring means or to draw liquid into the syringe manufacturers barrel via said hollow needle, a plurality of spaced-apart stops defined on an upper portion of the outer housing, and a control handle pivotal relative to the syringe manufacturers barrel, said handle having means to engage said stops for selective positioning of the outer housing and said needle thereon to extend the needle beyond the forward end portion of the outer housing, and to retract the needle within the outer housing end portion.
The syringe manufacturers of the present invention has a retractable needle positionable by a handle engageable in any of a plurality of stops or notches by simple manual manipulation, whereby the syringe manufacturers is convertible from a needle to a needle-less system by extending or withdrawing the needle. The needle may be extended for aspirating a solution into the syringe manufacturers from a bottle or an ampoule. The solution may then be injected into a patient directly or through an intravenous port. The needle may be retracted to expose the blunt tip of the syringe manufacturers for engaging a needle-less intravenous port.
An improved medical syringe manufacturers enables quick operation of a handle member to position a needle and syringe manufacturers barrel in selected positions to extend and withdraw a needle to provide a needle system or a needle-less system.
A syringe manufacturers according to claim 19, wherein the plurality of stops on the upper housing to receive the handle means comprises spaced-apart notches in the upper wall of the outer housing, and the handle means to engage in the notches is a handle portion adapted to engage in the notches.
