International Classification:

A61B 500

US Classification:

600576

Abstract:

The present invention relates to a blood collection system comprising a blood collection tube, a tube holder, and a self-blunting blood collection needle. A blunting member is deployed upon withdrawal of a blood collection tube from the tube holder, to blunt the needle and so safeguard the patient and the technician from inadvertent needle sticks. The blunting member is retracted to re-sharpen the needle when a subsequent collection tube is inserted into the holder. The mechanism effects blunting and re-sharpening of the needle with requiring that the technician manipulate the mechanism in a manner different from that of conventional, non-blunting blood collection needles. Four types of mechanisms are disclosed: a rack and pinion mechanism; a cylindrical cam mechanism; lever mechanisms and a reversing strap mechanism.

International Classification:

A61M 5/00

US Classification:

604110, 604263

Abstract:

A collar to which a needle protection housing is attached has a proximal end and a distal end. The proximal end of the collar has a number of internal protrusions that are fitted within the space defined by the two sets of flanges extending from the proximal portion of a needle hub. The distal end of the collar has a number of fingers or retainers that are used to grasp and removably couple a needle sheath. The needle sheath covers the needle that extends from the distal end of the needle hub before use. A needle protection housing is pivotally connected to the collar, and is pivoted to cover the needle after use. A channel or opening in the protective housing through which the needle passes is formed by a pair of progressively angled lips that extend longitudinally along the length of the housing.

Abstract:

A needle protection assembly has a needle hub with a proximal portion having two sets of spaced flanges and a distal portion having a number of arms for forming at least one catch and one slot. A collar with a needle protection housing has at its inner surface a number of protrusions fittable within the space defined by the two sets of flanges, when the collar is press-fitted to the needle hub, and a number of fingers that removably grasp a needle sheath that covers the needle extending from the needle hub. After the sheath is removed, the needle protection housing may be pivoted to cover the needle. Once the housing fully covers the needle, a spline inside the housing coacts against the catch at the needle hub to enable the needle hub to be removed from a syringe by rotating the housing.

International Classification:

US Classification:

604110, 604263, 604192

Abstract:

A safety needle assembly has a collar or ring that is rotatably mounted to a needle hub, which may be connected to a medical device such as a syringe. The needle assembly may be connected to the syringe by the user grasping the needle hub in first and second embodiments, or turning of the needle sheath in other embodiments. In all of the embodiments, the collar of the needle assembly may be rotated by turning the needle sheath, which is designed to interact with the collar. In some of the embodiments, the needle hub likewise interacts with the collar in such a way that by rotating the needle sheath, the needle hub is likewise rotated for connection to a syringe. When an exposed needle is to be covered, after the needle sheath has been removed, a housing connected to the collar is pivotally moved to cover the needle. Mechanisms are provided at both the collar and the housing so that once the contaminated needle is covered, the needle assembly may be removed from the syringe for disposal by rotating the needle housing. In all of the embodiments disclosed, the needle sheath does not come into contact with the needle hub and the collar is rotatable about the needle hub.

International Classification:

A61M 5/00

US Classification:

604263

Abstract:

A safety needle assembly has a needle hub and a collar. Integrally formed from the proximal portion of the needle hub is a ring that surrounds its luer base. At the distal portion of the needle hub there are coaxially formed circumferential flanges which act to allow the collar to be rotatable about the needle hub. A needle protection housing is connected to the collar and is pivotable to cover the needle that extends from the distal end of the needle hub. Before use, the needle extending from the needle hub is covered by a needle sheath that has a groove formed circumferentially at its proximal end that snap-fits to a circumferential rib formed at the distal end of the collar.

International Classification:

US Classification:

604/164060, 604/164080

Abstract:

A needle assembly includes a needle member () and a blunting member (), the needle member () containing a needle cannula (), the needle cannula () having a puncture tip () and having a needle passageway therethrough. The blunting member () contains a blunting probe () having a blunt end (). The needle cannula () and the blunting probe () are disposed telescopically one within the other without obstructing flow through the needle passageway, and are movable between a sharpened configuration in which the puncture tip () of the needle cannula () is exposed and a blunted configuration in which the blunt end () of the blunting probe () extends beyond the puncture tip () to blunt the needle assembly. The assembly may be combined with an accessory device (such as a catheter hub, guide wire, etc.) to produce an apparatus that is lockable in a blunted configuration and that can be released by the associated accessory, or may be configured to be released by manual manipulation.
