Title:

IV HYPODERMIC NEEDLE AND PASSIVELY SHIELDABLE NEEDLE DEVICE USED FOR BLOOD COLLECTION KIT

Document Type and Number:

Japanese Patent JP2004249100

Kind Code:

A

Abstract:

To provide a passively shieldable needle device used concurrently with a tube holder.

The needle device 12 comprises a needle cannula 20, a hub mounted to the needle cannula 20, and a tip guard 26 slidably movable along the needle cannula 20. The tip guard 26 can be slided into a distal position where the tip of the needle cannula 20 is safely shielded. A collapsible guard device 28 is mounted to the hub and includes a pair of collapsible leaf springs 86 extending from the hub to the tip guard 26. With a simple operation as releasing the grip on the collapsed leaf springs 86, the leaf springs 86 resiliently return to an uncollapsed condition and the tip guard 26 is propelled to the needle cannula 20 to engage around the tip of the needle cannula 20 for shielding.
