The present invention involves a sterilizable syringe allows for reduction in needlestick injuries using conventional sterile needles. The syringe allows for direct access to and the safe removal and disposal of needles. The device consists of a sterilizable, reusable hypodermic syringe to which a disposable needle is attached, and employs carpules containing injectable medication, viewable and either manually or automatically aspirating. Some embodiments have a protective sliding mechanism consisting of an open frame bearing one or more protective collars, one at the furthermost end of the frame and an optional second one at a more proximal position. The protective mechanism may be extended to protect an exposed needle tip and retracted during an injection. With the protective mechanism extended, the needle mounting hub is exposed to allow for its exchange or removal and safe disposal. The protective mechanism is engaged until immediately prior to the delivery of medication, disengaged on delivery, and engaged after delivery.

A monitoring device for monitoring operation of a drug delivery device and to a respective drug delivery device is presented in which a fastening member releasably attaches the monitoring device to an axially elongated housing of the drug delivery device, a sliding member is shiftable relative to the fastening member in an axial direction and being adapted to operably engage with at least one dose setting component of the drug delivery device to follow an axial displacement of the dose setting component relative to the housing component, a first sensor arrangement for detecting a rotation of the dose setting component relative to the fastening member, a second sensor arrangement for detecting an axial displacement of the sliding member relative to the fastening member, and a processing member coupled to the first and to the second sensor arrangements to process first and second signals obtainable from the first and from the second sensor arrangements for determining the size of a dose dispensed by the drug delivery device.

There is provided a pharmaceutical syringe unit that is mounted to a pharmaceutical injection device main body and holds a pharmaceutical syringe, in order to mount the pharmaceutical-filled pharmaceutical syringe to a pharmaceutical injection device, wherein a syringe cover is slid in the forward and backward direction with respect to a distal end cap by the operation of the pharmaceutical injection device main body, allowing movement between a needle insertion position at which the insertion of an injection needle into a target is completed, and a needle withdrawal position at which the withdrawal of the injection needle from the target is completed, and the range over which the syringe cover can be slid by a guide component is greater than the distance between the needle insertion position and the needle withdrawal position.

A medicant injection device includes a compressible body, a tip, and an outer luer body. The compressible body has a proximal end, a distal end, and a plurality of bellows, and defines an inner cavity for holding a liquid medicant. The tip is positioned at the proximal end of the compressible body. The outer luer body includes internal threads, and is positioned over and engaged with the tip to form a first fitting therewith. The first fitting is configured to be connected with a second fitting. A medicant injection device includes a compressible body having first and second arms, a receptacle interconnected with the compressible body and defining an inner cavity, and a first fitting configured to engage a second fitting. The compressible body is configured to be compressed by forcing the distal end of the first and second arm toward each other.

An injection system includes: a syringe having a cylinder to be filled with a chemical liquid, a flange projecting laterally from the cylinder, an end portion through which the chemical liquid passes when the chemical liquid is pushed out, and a syringe screw portion formed on a side opposite to the end portion; an adapter for holding the syringe, the adapter having a receiving portion for receiving the cylinder, a regulating wall for abutting the flange, and an adapter screw portion engaged with the syringe screw portion; and an injection device provided with a holder to which the adapter is to be attached. In this injection system, a tightening direction by the syringe screw portion and the adapter screw portion is set in a direction toward the end portion.

A hypodermic interface assembly includes a cannula and a hub. The hub is defined by a first portion and a second portion. The second portion of the hub is breakably-connected to the first portion of the hub. The cannula is joined to the second portion of the hub. The second portion of the hub is defined by an outer head surface portion having a first geometry. The second portion of the hub also includes an outer neck or groove surface portion having a second geometry. The first geometry of the outer head surface portion is greater than the second geometry of the outer neck or groove surface portion.

Various embodiments of a “smart” drug delivery pen are provided which include a drug delivery pen having an inertial sensor or accelerometer. A system is also provided that includes the smart drug pen in conjunction with a data management unit(s) DMU. Various exemplary methods for use of the pens and systems are also described and illustrated.

Disclosed is an auto-injector apparatus for receiving a safety syringe, the safety syringe including a sheath deployable on actuation of a plunger to a position at least partially covering a needle of the syringe, wherein the apparatus is configured to allow movement of the sheath to a closed position that substantially covers the needle.

A supplementary device is configured to be attached to a drug delivery device. The supplementary device comprises a non-contact sensor configured to output signals indicative of the position of a moveable component within the drug delivery device. The supplementary device further comprises a processor configured to receive the signals output from the non-contact sensor. This processor is additionally configured to determine, based on the signals, whether the drug delivery device is in a pre-activation state or a post-activation state.
