Problems solved by technology

Such incorporation of needle protection devices to the needle and syringe requires additional time.
This embodiment does not provide a sterile luer to which the syringe is mated.
Thus, a user has to tear the pouch to get to the device.
As is well known, such pouches are oftentimes difficult to tear, particularly when they have been designed to be sufficiently strong to prevent accidental tearing.

Embodiment Construction

With reference to FIG. 1, the safety needle protection package (cartridge) 2 of the present invention is shown. As illustrated, package 2 has a base 4 to which a housing 6 is hingedly attached via a living hinge 8. Base 4 has an end portion 10 for receiving hub 12 of a needle 14 of a needle assembly. It should be noted that needle 14 may actually be integrated to end portion 10 or added to end portion 10 later. As shown in FIG. 1, end portion 10 comprises a protrusion 11 extending from a support 13 of base 4. Extending from support 13 and surrounding protrusion 11 is a portion 26, the lower half of which is internally threaded for receiving extension arm 15 of hub 12.

Base 4 further has another end portion 16 which is adapted to mate with a syringe (not shown). Integrated to housing 6 is a secure means 18 which, for example, may be configured into the shape of a hook, as that shown in FIG. 2C. Housing 6 can be pivoted from the direction as shown in FIGS. 1 and 2A to a direction subst...

Abstract

A needle protection safety package, instead of being enclosed in a pouch or other containment wrappings, has fitted thereto at respective ends thereof caps or sheaths so that both the needle and the end to which a syringe is adapted to mate remain enclosed and sterile. Such an arrangement enables easy transport of the safety needle package and provides convenience for the user at the same time. The safety package is further designed to prevent burring of the tip of the needle as the cap or sheath is removed from the needle portion of the package. A further embodiment of the safety package incorporates a locking mechanism which prevents contact between the needle and the housing as the housing is pivoted to envelop the needle after use.

Description

FIELD OF THE INVENTIONThe present invention relates to needle protection devices and more particularly to a convenient to use safety needle package.BACKGROUND OF THE INVENTIONIn a medical emergency, time is of the essence. For example, medical personnel have to quickly assemble a syringe to a needle for injecting medicant to a patient. With the recent onslaught of contagious diseases, to safeguard medical personnel, and bystanders, needle protection devices have been added to prevent unwanted needle sticks. Such incorporation of needle protection devices to the needle and syringe requires additional time.A particular needle protection device having a needle integrated to a base, which in turn has connected thereto a pivotable housing, is disclosed in Landis U.S. Pat. No. 4,664,259. To maintain sterility for the device, in one of the embodiments, a frangible strip is provided to seal the housing to the base so that, in order to use the device, the frangible strip has to be peeled awa...
