Safety pen needle device
The present invention relates to a safety pen needle device comprising a first needle shield (60) and a second back-end needle shield (90). During the injection the first needle shield (60) is moved to en retracted position this movement causes a actuation sleeve (31) to rotate. Said rotation causes a holding member (96, 98) provided on the second needle shield (90) to be released. When the first needle shield (60) is moved from the retracted position to a extended position the actuation sleeve (31) is rotated further so that a first guide member (74) on the first needle shield (60) abuts a first stop member (34) arranged on said actuation sleeve (31). After an performed injection both shields are moved to extended positions by the rotation of an actuation sleeve (31). After the injection the shield are locked it their extended position.
Safety needle assembly
A safety needle assembly is provided herein which includes a hub; a needle fixed to the hub; a first shield having a tubular body at least partially encircling a portion of the needle, wherein in an initial state, the first shield extends from the hub; a second shield having a tubular body at least partially encircling a portion of the needle; a biasing element disposed to urge the second shield distally towards a distal end of the needle; and, a releasable retaining arrangement for releasably retaining the second shield in a first state. Upon a predetermined extent of proximal movement of the first shield relative to the hub, the second shield is released to a second state in which the distal end of the needle is covered. Advantageously, two shields are provided for at least partially covering a needle with one of the shields acting as a trigger.
Needle assembly having slidable collar to control radial engagement of sleeve segments with injection pen threads
A needle assembly for an injection pen (22) has a sleeve (21) supporting internally a double-ended needle having an injection end and a non-injection end (25). The end of the sleeve surrounding the non-injection end (25) of the needle is divided into deformable segments (28) and is internally threaded for interengagement with a threaded boss (23) of the injection pen (22). A collar (29) is mounted on the sleeve (21) for sliding movement between a first position where the collar (29) overlies the segmented end and maintains interengagement of the threads at that end with those of the injection pen boss (23) and a second position where the segments may expand radially to come free of the injection pen boss (23). The needle may be mounted on a carrier (68) slidable with respect to the sleeve (21), the carrier (68) being coupled to the sleeve (21) for movement thereby.
Passive safety pen needle assembly
In a first aspect, a safety pen needle assembly is provided herein which includes a hub and a needle fixed to the hub which extends distally from the hub so as to define an injection length. A first shield is slidable relative to the hub from a first state, in which the shield covers at least a substantial portion of the injection length of the needle, to a second state, in which at least a substantial portion of the injection length of the needle is exposed; and, a second shield is slidable from a first position, in which the shield covers the proximal end of the needle, to a second position, in which the proximal end of the needle is exposed. A biasing element is disposed between the first and second shields configured to simultaneously urge the first shield distally and the second shield proximally.
NEEDLE ASSEMBLY
A needle assembly (1) includes a cover (5)(7) provided to be movable to a first position where a cannula (2)(3) is exposed and a second position where a distal end projects further than the cannula.
In the cover, circumferential-direction locking sections (25)(43) or front-back-direction grooves (24)(42) continuing to the circumferential-direction locking sections or engaging protrusions (5a)(33a) movable along the circumferential-direction locking sections and the front-back-direction grooves are provided.
Pen needle
A pen needle includes a hub supporting a needle and a distal needle shield that can retract to expose the needle and return to an extended position to cover the needle. A proximal needle shield moves to an extended position to cover a proximal end of the needle. A spring extends between the distal and proximal needle shields to bias the distal and proximal needle shields to their respective extended positions. A locking member on the distal needle shield cooperates with the hub to lock the proximal and distal needle shields in their respective extended positions. An indicator in the hub couples to the distal needle shield when the distal needle shield is moved to a retracted position. The indicator moves with the distal needle shield to the extended position of the distal needle shield where the indicator indicates that the pen needle is no longer usable.
DETACHABLE NEEDLE PROTECTION CAP FOR INJECTION DEVICES
The invention relates to a detachable needle protection cap for injection devices and to a method for producing same. The detachable needle protection cap comprises a housing and at least two shell parts which can be attached to an outer surface of the housing, the shell parts being fastened to an outer surface of the housing. The shell parts can mutually prevent removal of the shell parts.
Variable length injection syringe
A syringe assembly includes a syringe barrel (12) having a proximal end and a distal end, a needle hub (20) supporting the needle and coupled to the distal end of the syringe barrel (12). A moveable shield (36) is included for sliding from a first position where the needle is exposed a first length, a second position where the needle is exposed a second length less than said first length, and a third position covering a distal end of the needle. A locking mechanism (48, 86) is included to retain the shield in the second position while enabling the shield to slide to the third position, and to lock the shield in the third position to prevent re-use of the syringe.
Pen Needle Outer Cover Concepts
Some examples provide a non-transitory computer readable medium having instructions executable by a processor of a computing device. The instructions can cause the processor to establish remote access by the computing device to a network-based storage resource, and establish the remote access based on a hardware identifier associated with the computing device. The instructions can cause the processor to generate, at the computing device, a local index for the remote data stored on the network-based storage resource and available to the computing device through the remote access. The instructions can cause the processor to provide, based on the local index, local access to the remote data through a virtual file system at the computing device.
Pen Needle Having a Linear Needle Cover
The present invention provides a pen needle (100) having a hub (105) with a first cylindrical compartment and a second cylindrical compartment, wherein the first cylindrical compartment having a smaller circumferential size than the second cylindrical compartment, and a needle (101) held by the hub (105) across the length of the hub (105) defining a center axis, wherein a tip of the needle (101) is exposed within a space of the second cylindrical compartment. The pen needle (100) comprises a spring loaded needle cover (124) installed in the first cylindrical compartment of the hub (105), wherein the spring loaded needle cover (124) comprises a distal end slidable along the center axis to cover the tip of the needle, and two opposingly cantilevered fingers (412, 414), each finger further comprises a protruding peg (422,424) adapted as stopper for restricting movements of the needle cover (124); and a retainer (126) disposed within the second cylindrical compartment and movable linearly in a restricted manner; the retainer (126) comprises a center aperture for receiving the spring loaded needle cover (124).
