International Classification:

A61M 500

US Classification:

604263

Abstract:

A needle shield assembly having a single-use cannula lock of the present invention includes a needle cannula having a proximal end, a distal end and a lumen therethrough. A hub includes a proximal end for connection to a fluid transfer device and a distal end connected to the proximal end of the needle cannula. A collar is rotationally connected to the hub so that the collar can be rotated around the hub. An elongate needle cover removably engages the hub and covers the needle cannula. An elongate needle shield having a proximal end and a distal end is hingedly connected, through its proximal end, to the collar. The needle shield includes two sidewalls defining a longitudinal opening and a back wall between said side walls defining a recess having an interior surface. The needle shield is capable of pivoting from an open position wherein the needle cannula is exposed, to a closed needle protecting position wherein at least part of the needle cannula is within the longitudinal opening of the needle shield. The needle shield assembly further includes structure for preventing the needle shield from pivoting into the closed position unless the needle cover is removed, and structure for locking the needle shield in the closed needle protecting position when the needle shield is pivoted into the closed position.

International Classification:

A61M 500

US Classification:

604263

Abstract:

A shieldable needle assembly includes a needle guard slidably movable along a needle cannula from a proximal position where the distal end of the needle cannula is exposed to a distal position where the distal end of the needle cannula is safely shielded within the needle guard. A hinged arm assembly connects the needle guard assembly to needle hub. A trigger is articulated to the needle hub at a location proximally of the hinged arm. Distally directed digital forces cause the trigger to rotate such that the trigger urges the hinged arm from a collapsed condition to an extended condition.

International Classification:

A61F 1315
A61F 1320

US Classification:

604378

Abstract:

Improved pads for application to the body to absorb body fluids are disclosed. Menstrual pads having a plurality of projections which are most preferably filled with a superabsorbent material are disclosed, as well as methods for making same. The present invention discloses the use of novel melt-blown technology to form a surface having hollow projections which are then filled with superabsorbent. The present invention is directed to menstrual pads, as well as other pads which may be placed against the body, such as bandages. In the latter, medicinal compounds replace superabsorbents as the preferred material within the projections. In certain embodiments, a wicking layer, preferably comprised of peat moss based absorbent product is disposed between a cover layer and the projections containing superabsorbent.

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61M 532

US Classification:

604192

Abstract:

A protective safety cap assembly for the passageway of a medical device is provided. The safety cap assembly includes a cap that is guided for sliding and pivotable movement between a closed position where the proximal end of the medical device is easily accessed and a closed position where the proximal end of the medical device is sealed. The medical devices which can be protected by the cap assembly include hypodermic syringes, stopcock assemblies associated with I. V. lines and catheters, or the like. A medical worker holding the medical device in one hand can easily and repeatedly move the cap between the opened and closed position with a thumb or forefinger of the hand holding the medical device.
