Title:
REVERSIBLE DISPOSABLE BLOOD VESSEL RESIN NEEDLE
Document Type and Number:
WIPO Patent Application WO/2010/036003
Kind Code:
A2
Abstract:
The present invention provides a reversible disposable blood vessel resin needle, which comprises a cylinder having a resin tube at the forward end, through which an injection solution is injected into a blood vessel; a metal needle furnished in the cylinder to optionally slide back and forth and disposed at the forward end to be exposed to the exterior via said resin tube, and a piston, formed on one side of the metal needle, which has a water pathway formed such that an injection solution may be supplied into the cylinder which is extended to and formed with a body part as a single unit with the forward end and an elastic tube part formed as an extension of said body part and furnished at a reduced thickness, having elasticity and with a terminal end part that is joined to the end part of said piston. In the present invention of such configuration, a part of the body of the cylinder is formed into a stretching tube of a flexible material and the end part is combined and connected with the piston to afford a streamlined configuration, wherein inner sealing properties of the cylinder may be maintained with stability, and an injection solution such as blood or an aqueous solution may be blocked from being exposed externally and sources of contamination blocked from infiltration, so that advantageously enhanced reliability is anticipated. In addition, puncture due to a metal needle caused by operator carelessness may be prevented in advance, thus enhancing useful effects including safety and convenience for handling.
