Abstract: An injection 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 sleeve (32) is positioned on the syringe barrel and needle hub for sliding between a first position where the needle is covered and a second position exposing the needle. The sleeve (32) is biased to the extended position to cover the needle. The sleeve has a distal end (38) and a proximal end (40). During use, the syringe is positioned against the skin of the patient so that distal end of the sleeve contacts the skin of the patient before the needle so that lateral or angular force applied relative to the surface of the skin is absorbed by the sleeve to inhibit sliding of the sleeve and resist bending of the needle during insertion.

Abstract: An accessory (60) configured to be attached to a medical device (10) to disinfect a skin surface or a portable medical device surface (54). The accessory (60) comprising a plurality of disinfecting materials (68), and a mounting mechanism (62) that is configured to attach and detach the accessory (60) to the medical device (10).

Abstract: A multiple pen needle or syringe needle storage and dispensing system where a plurality of needle devices such as pen needles including a cover can be disposed on strip, where the strip serves a seal for multiple needle devices. Each needle device can be peeled off the strip unsealed for immediate use for example in an injections device, or separated from the strip sealed for later use.

Abstract: A needle hub assembly for a pen needle includes a needle hub, a cannula or needle coupled to the needle hub, a retractable and compressible sleeve covering at least one end of the cannula, and an outer cover. The outer cover encloses the needle hub and the retractable sleeve. The retractable sleeve is coupled to the hub to cover the end of the cannula where the sleeve can pass through or can be pierced by the cannula and the sleeve retracts axially on the cannula. The sleeve is resilient and returns to an original configuration when an insertion force is released. The needle hub can have a first sleeve to cover a patient end of the cannula, and second sleeve to cover a non-patient end of the cannula where the sleeves retract onto the cannula or hub and expand to the original configuration to cover the ends of the cannula.

Abstract: A pen needle is disclosed for coupling to a delivery device and piercing a septum on the delivery device. The pen needle includes a collar having a side wall, an open proximal end, and a distal end having a coupling member, a needle hub rotatable independently of the collar, where the proximal end of the needle hub has a coupling member coupled to the distal end of the collar. The collar rotates independently from the needle hub so that the collar screws onto the threaded end of the delivery device while the needle hub does not rotate and the needles advance to pierce a septum of the delivery device without rotating the hub and the needles.

Abstract: A pen needle assembly (30) includes pen needle hub (32) and an inner shield (34) for covering a needle (46) extending from the needle hub (32). The needle hub (32) and inner shield (34) include a coupling mechanism (52, 54) to assist in removing the inner shield from the needle hub. In one embodiment, the needle hub (32) includes a threaded connection (52) for mating with a threaded connection (54) on the inner shield (34) to assist in removing the inner shield by a twisting motion to disconnect the inner shield from the needle hub. The threaded connection (52, 54) can have a pitch greater than an axial length of a post on the needle hub.

Abstract: A medical device and method configured to disinfect a skin surface, the device comprising a power source that provides electric power, a light emitting source that uses electric power received from the power source to disinfect the skin surface, and a switch that is configured to be operated by user action, wherein upon activation of the switch, the electric power from the power source is received by the light emitting source to emit visible light and disinfect the skin surface.

Abstract: A cap configured to disinfect a medical device or portion thereof, the cap comprising a power source that provides electric power, an electromagnetic radiation source that uses the electric power received from the power source to emit photons for disinfection and a switch that is configured to be operated by user action, wherein upon activation of the switch, the electric power from the power source is applied to the electromagnetic radiation source to radiate photons onto the medical device or portion thereof.
