Abstract

A needle assembly (100) for percutaneously infusing fluids to a body and / or withdrawing fluids from a body is provided. The needle assembly (100) comprises a polymeric body (101) having a passageway (102) in a proximodistal direction. A wing assembly is secured to the body (101), and the wing assembly including first and second wings (103) extending laterally in opposite directions from said body (101). A hollow needle (104) is arranged in said passageway (102), such that it extends distally from said body (101), wherein said needle (104) is press fitted or interference fitted in said passageway (102).

Description

technical field [0001] The present invention relates to an apparatus and method for the percutaneous infusion of fluid into and / or withdrawal of fluid from the human body. More precisely, the present invention relates to a needle assembly for percutaneously injecting fluid into and / or withdrawing fluid from the human body, comprising: a main body having a channel in a direction proximal to the distal end; fixed to the main body a wing assembly comprising first and second wings extending laterally from the body in opposite directions; and a hollow needle disposed in the channel, the hollow needle extending distally from the body. Background technique [0002] Needle assemblies are commonly used to percutaneously inject fluids into and / or withdraw fluids from the body. The needle assembly is typically retained in the vasculature while one or more assemblies are connected and disconnected from the needle assembly to perform infusion / withdrawal operations. To facilitate insert...
