The disclosure concerns an insulin delivery arrangement including a hand-operable insulin delivery device which includes an adjusting unit for presetting of an insulin dose and an applicator unit that can be triggered to deliver the preset insulin dose to a user. In order to ease burden of insulin dosing, a dose converter is adapted to receive an actual setting for the insulin dose as an input and to provide as an output a carbohydrate value equivalent to an amount of meal carbohydrates which can be compensated by the respective insulin dose. A display is used for displaying the carbohydrate value in parallel to the insulin dose.

Apparatus for recording information concerning the use of an injection device, the apparatus comprising: one or more sensors for providing information indicative of how the injection device is used; a processor configured to analyse said information detected by the one or more sensors to determine use information, said use information corresponding to how the injection device is used; and a memory for storing said use information in an image format such that said use information can be retrieved from the memory and displayed in an image.

A needle end and a safety syringe are provided, belonging to technical field of medical instruments. The safety syringe includes an injection end, a liquid storage device, and a base. The injection end includes a needle base, an injection needle, and a needle guard assembly. The injection needle is fixed to the needle base. The needle guard assembly is connected to the needle base. The needle guard assembly includes a protective casing and a spring, wherein a first terminal of the spring is connected to the needle base and a second terminal of the spring is connected to the protective casing. The liquid storage device includes a liquid storage container and a liquid storage sleeve. The liquid storage is sleeved on an outer surface the liquid storage container, wherein the liquid storage container is detachably connected to the injection end. The base is detachably connected to the liquid storage device.

An optical decoding system including an optical sensor integral with or attachable to a housing of a drug delivery device and configured to be directed at first and second rotatable components of a dose setting and dispensing mechanism of the drug delivery device and a processor configured to: (i) cause the optical sensor to capture images of the first and second rotatable components at least at the beginning and end of a medicament dose dispensing process; (ii) determine a rotational position of both the first and second rotatable components in each of the captured images; and (iii) determine from the rotational positions of the first and second rotatable components an amount of medicament delivered by the dose setting and dispensing mechanism of the drug delivery device.

An apparatus including a control unit, a sensor arrangement configured to measure the fill level of a medicament within a container of a drug delivery device, and a cap sensor configured to detect at least partial removal of a cap from the drug delivery device is described. The control unit is configured to be awoken from a dormant state in response to detection by the cap sensor that the cap has been at least partially removed from the drug delivery device. The sensor arrangement is configured to start measurement of the fill level subsequent to the control unit being awoken from the dormant state.

A syringe assembly for administration of a neurotoxin, the syringe assembly comprising: a syringe comprising: a clear syringe barrel with dosage markings completely encircling the clear syringe barrel; and a plunger having a plunger body and a clear inverted plunger tip; and a needle assembly comprising a needle and a sealing hub for removably attaching the needle assembly to the syringe, wherein the needle is approximately 0.15 inches to approximately 0.3 inches in length and has a gauge of approximately 27 gauge to approximately 35 gauge.

A sensing system for determining a zero position of a medication delivery device. The sensing system includes at least one actuator member, a biasing member, a stop surface and a sensor. The stop surface is structured and arranged within the device housing for abutment by a push surface of the at least one actuator member as a screw element of the device screws to a zero position from a dosing position. The abutment forces the at least one actuator member to move relative to the screw element from a first position to a second position against a resistance provided by the biasing member. A sensor within an electronics module is adapted to recognize the at least one actuator member at the second position.

A method of verifying that a first unit and a second unit being mounted to each other are correctly paired, the first unit comprising a first visual identifier and the second unit comprising a second visual identifier, the method comprising the steps of (i) capturing an image of the first and second unit mounted to each, the image comprising both the first and the second visual identifier, and (ii) processing the captured image to (a) identify the first and the second visual identifier, and (b) determine whether the captured identifiers represent a predefined combination of visual identifiers to thereby verify the pairing.
