Problems solved by technology

This complex structure results in increased manufacturing and assembly costs
In addition, to operate the needle assembly, the operation of moving the needle tip shield to the proper position at the tip end of the needle tube needs to be done manually by the user, thus there is a potential danger of being stuck by a needle

Embodiment Construction

[0028] The same reference numerals in the above-mentioned drawings represent the same technical features, Figure 6 A blood collection device 10 of the present invention and its associated features are shown. The general term for the invention is a blood collection device which also includes a shieldable needle assembly for the device.

[0029] Such as Figure 6 As shown, blood collection set 10 includes a shieldable needle assembly 12 , a flexible tube 14 extending from needle assembly 12 , and a securing mechanism 16 mounted on flexible tube 14 . Details of shieldable needle assembly 12 of blood collection set 10 are shown in FIGS. Securement mechanism 16 is used to attach a blood collection container (not shown), which may include mating surfaces such as luer type type known in the art.

[0030]Cannula 20 includes a proximal end 22 and an opposite distal end 24 with a conduit 26 extending from proximal end 22 to distal end 24 of cannula 20 . The distal end 24 of the nee...

Abstract

The present invention is directed to a shieldable blood collection set as well as a needle assembly for use therein. The needle assembly includes a needle cannula having a puncture tip at a distal end thereof; a hub which supports the needle cannula; and a shield axially movable between a non-shielding position, in which the puncture tip of the needle cannula is exposed from the shield, and a shielding position in which the shield covers the puncture tip. A pair of extendable members interconnects the hub and the shield. The pair of extendable members are moveable between a mating position forming a unitary structure; a lateral position forming a pair of wings extending from opposing sides of the needle assembly; and an extended position causing the shield to move from the non-shielding position to the shielding position.

Description

[0001] Related applications that can be cross-referenced [0002] This application claims the benefit of US Provisional Patent Application No. 60 / 365,436, filed March 19, 2002. 1. Technical field [0003] The present invention relates to a blood collection device with a needle that is safe and easy to operate. More particularly, the present invention relates to a needle assembly needle assembly having a safety shield that can be advanced in a retracted state to protect from a spent needle tip. 2. Background technology [0004] Injecting drugs into a patient or withdrawing fluid from a patient often requires the use of a disposable medical device having a medical needle. These disposable devices generally include blood collection needles, fluid handling needles, and combinations thereof. Current medical practice requires that the liquid container and needle assembly used in these devices be low cost and suitable for single use. Therefore, the existing blood collection devi...
