  • Patent number: 10596325
    Abstract: A pen-type drug injection device is disclosed which comprises a housing having a longitudinal axis, a threaded piston rod, a guide member for guiding the piston rod in a drug dispense operation, and a cartridge holder for receiving a cartridge, wherein the cartridge holder is detachable from the housing and wherein the guide member comprises an iris type aperture defined by a plurality of threaded pivotable segments. The drug delivery device is configured such that the aperture increases in diameter when the cartridge holder is being detached from the housing, such that the piston rod is free of the threaded engagement with the guide member and can be reset or pushed back to its initial position, and decreases in diameter when the cartridge holder is attached, such that the threads on segments reengage the piston rod.

  • Patent number: 10479154
    Abstract: A utility sled is formed from a lightweight material and includes a handle flexibly attached to the front end thereof. The handle includes a hook that is seated within a small opening of the utility sled when not in use. A pair of retractable wheels is attached to an exterior of each sidewall of the utility sled. The sidewalls are biased outward when no load is present. When loaded, the sidewalls advantageously tend to straighten vertically. The formed bottom of the sled includes a plurality of ribs which both add strength to the sled as well as function as sled runners when the wheels are retracted. The ribs operate to reduce friction between the sled bottom and the underlying surface.
