The present invention provides a needle unit (10) for use with a pen injection device, wherein the needle unit (10) comprises a needle shield (50) and an axially movable needle hub (25).

Devices and methods are disclosed for assisting a user of a drug delivery device with an application executing on a mobile computing device. The mobile computing device may receive information from the drug delivery device related to its condition and/or operation and subsequently select an informational and/or instructional prompt to be displayed to the user based on the received information. The mobile computing device may also generate a display in the application including the selected informational prompt and/or the instructional prompt. Accordingly, the user of the drug delivery device can be guided through the drug delivery process in real time, thereby reducing the likelihood of improper or incomplete use of the drug delivery device.

A medicament delivery device is presented having a front-end device with a front-end housing and a delivery member cover that moves along a longitudinal axis between an extended position and a retracted position relative to the front-end housing, and a medicament container holder arranged in the front-end housing that receives a medicament container; and a reusable base device that is detachably connected to the front-end device, the base device has a plunger, a motor to drive the plunger inside the front-end housing, and wherein the motor drives the plunger from a second end position back to an initial end position, and a motor switch having a first switch position that changes to a default switch position by displacement of the delivery member cover when the delivery member cover is moved back from a retracted position to an extended position causing the motor to rotate in a reverse direction and drive the plunger from the second end position to the initial end position.

The present invention provides a needle unit (10) for use with a pen injection device, wherein the needle unit (10) comprises a needle shield (50) and an axially movable needle hub (25).

An apparatus for use with a syringe for providing a safety syringe, the safety syringe including a plunger configured during an inward stroke to expel a substance from a hypodermic needle attached at an open end of a barrel of the syringe, the apparatus including: a biasing member configured to bias a sheath towards a closed position at least partially covering the hypodermic needle, wherein the biasing member is configured to be released at a point on the inward stroke of the plunger to urge the sheath towards the closed position.

In one aspect there is provided a self-removing animal injection apparatus for injecting an animal with a liquid medication. The apparatus comprises a shaft having a first end and a syringe. A needle is provided at the first end of the shaft and defines a longitudinal direction. The needle is in fluid communication with the syringe. First and second disengaging members are movable substantially along the longitudinal direction and operable to assist with disengagement of the animal injection apparatus from the animal, once at least some of the liquid medication has been injected into the animal.

Disclosed is a Huber needle assembly that may include an upper body connected to a lower body, the assembly being structured to retain a needle for insertion/extraction of the needle into/from an insertion site. The upper body can statically retain the needle while the lower body may slidably receive the needle. The lower body can further include a catch that engages a tip of the needle and/or misaligns the tip of the needle with a needle aperture of the lower body to place the assembly in a safety-lock position, preventing rebound, needle-stick injury, and/or any type of exposure of the needle tip to an environment outside of the lower body. The assembly can further bias the needle in a direction so as to prevent re-emergence of the needle tip after being withdrawn into the lower body.

A dosage verification system for use prior to administering an injection of a medicinal fluid drawn into a medical syringe, the system comprising a medical syringe having a barrel with an outwardly facing, flat indicia display surface, plunger having a plunger seal disposed inside and slidably engaging an inwardly facing wall of the barrel and a plunger handle projecting rearwardly from the barrel, and a hypodermic needle projecting forwardly from the barrel, all in combination with an imaging device configured to view and selectively capture, store or transmit a digital image of the plunger position relative to the barrel when a dose of the medicinal fluid is drawn into the fluid chamber of the barrel prior to an injection to verify and provide a record of the dosage drawn, and to alert a user prior to injection when an incorrect dosage is drawn into the fluid chamber of the syringe.

A device configured to administer a medication can comprise a lower housing that includes a housing latch. The device can further comprise a needle guard that is movable relative to the lower housing along a first direction from a first position to a second position so as to expose a needle, and an upper housing supported relative to the lower housing. The upper housing can be configured to move with respect to the lower housing along a second direction from a pre-use position to a dispensed position. The housing latch can releasably interfere with the upper housing when the upper housing is in the pre-use position so as to prevent the upper housing from moving toward the dispensed position, and the movement of the needle guard toward the second position, causes the interference to be removed, thereby allowing the upper housing to move toward the second position.

Device for dispensing a substance having: a dispensing element through which the substance can be dispensed, a displaceable protective element for the dispensing element, a drive element that is coupled with the protective element and a feedback element which can generate a signal when or after a predefined quantity or the entire quantity of the substance to be dispensed has been dispensed characterized in that the feedback device is coupled with the drive element.
