International Classification:

A61M 5/00

US Classification:

604110, 60416408, 604192, 604263

Abstract:

A needle guard is disclosed. The needle guard includes a binding plate defining a multi-slot aperture adapted to receive a needle cannula therethrough. The needle guard also includes a biasing member for biasing the needle cannula within the multi-slot aperture, and a sensing arm connected to the binding plate. The sensing arm is adapted to contact a portion of the needle cannula, and is positionable for restricting movement of the needle cannula. The multi-slot aperture may include a first region having a first dimension, a second region having a second dimension, and optionally, a third region having a third dimension with the third dimension being smaller than the second dimension and the second dimension being smaller than the first dimension.

International Classification:

A61M 5/00

US Classification:

604263, 604274

Abstract:

A hub assembly, such as for long needles, is disclosed. The hub assembly includes a needle hub having a proximal end and a distal end, having a cannula extending therethrough and protruding from the distal end, with the needle hub having a first engagement portion. The hub assembly also includes a stylet handle having a stylet extending therefrom. The stylet is adapted to be received within a portion of the cannula, with the stylet handle having a second engagement portion. Engagement of the first engagement portion of the needle hub and the second engagement portion of the stylet handle forms a positive lock in which at least a portion of one of the first and second engagement portions is held within the other of the first and second engagement portions in an unbiased state.

International Classification:

A61M 5/315

US Classification:

604222

Abstract:

A stopper includes a main body portion defining an open rearward end configured to receive the plunger rod, an engagement portion provided along an inner circumference of the main body portion configured to engage at least a top portion of the plunger rod, a closed front end forming a flexible roof, and a first perimetrical skirt extending around an outer circumference of the main body portion toward the closed front end of the main body portion. When fluid pressure is increased inside the syringe barrel during an injection, the flexible roof expands in a radial direction toward an inner wall of the syringe barrel, the first perimetrical skirt is forced against the inner wall of the syringe barrel, and an engagement between the plunger rod and the engagement portion forces the main body portion to expand in the radial direction toward the inner wall of the syringe barrel.

Inventors:

Andrew Wong - East Hanover NJ, US

International Classification:

A61M 5/32

US Classification:

604263

Abstract:

A passive safety needle device is disclosed having a housing, a needle hub, a needle cannula, a retractable sheath, a spring to bias the retractable sheath in a distal direction to cover the distal end of the needle cannula, a radial protrusion to cause the spring to move from the proximal spring position to the distal spring position, and a catch to secure the distal end of the spring to the distal end of the housing. The spring may bias the retractable sheath in a distal direction to cover the distal end of the needle cannula. The radial protrusion causes the spring to move from a proximal spring position to the distal spring position towards the catch located at the distal end of the housing.

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61M 5/32

US Classification:

604263

Abstract:

A safety needle device having a housing, a retractable sheath, and a needle cannula. The retractable sheath includes a tubular portion that is slideably mounted about a portion of the housing to completely or partially encase the length of the cannula. The retractable sheath includes a sheath bevel at the distal end having a blunted or angled tip. The angled tip being configured to suitable injection angles and may be fixed or rotatable. The sheath bevel may include a skin-engaging contact surface at the distal end. The needle may be connected to a needle hub at the proximal end of the housing and includes a needle bevel at the distal end. The sheath bevel and needle bevel may be offset from each other. A safety needle device having a retractable sheath having a graduated injection depth gauge to indicate needle penetration is also disclosed.
