The present disclosure is directed to a window element and a drug delivery device, like a pen-type injector, that provides for administration by injection of medicinal products from a multidose cartridge. The drug delivery device may comprise a housing, a dose setting member, a dial, a drive member, a clutch and/or a clicker. The window element comprises a first member with a window and being made from a rigid material, a second member and a third member, each made from an elastically deformable material and being attached to the first member.

A method of recording a medicament dose using a data collection device comprises capturing an image of a medicament dose indicator of a medicament delivery device, adjusting a scale of said image, adjusting said image for skew of one or more characters displayed by the medicament dose indicator, determining the position of at least one of said one or more characters in the image, identifying the at least one character using optical character recognition and determining a medicament dose indicator by the medicament dose indicator based on a result of the optical character recognition. The method may be performed using a handheld electronic device comprising a camera, such as a cellphone, a tablet computer or other device. A computer program for controlling a data collection device to perform the method may be provided in the form of a software application or “app”.

A method of recording a medicament dose using a data collection device comprises capturing, by a video camera of said data collection device, a video showing a medicament dose indicator of a medicament delivery device, adjusting a scale of an image of said medicament dose indicator in said video, adjusting said image for skew of one or more characters displayed on a component of the medicament delivery device in said video, determining the position of at least one of said one or more characters in the image, identifying the at least one character using optical character recognition and determining a medicament dose shown by the medicament dose indicator based on a result of said optical character recognition. The method may include determining whether more than one delivery of medicament is recorded in the video and, if so, whether said more than one delivery includes one or more prime shots, so that an overall dosage delivered to a user may be determined based on multiple determined medicament doses. A wearable electronic device comprising a video camera may be used to obtain and analyse the video, for example, using software provided in an “app”. The wearable electronic device may be configured to be worn on the head of a user, to capture the video from the user's point of view.

A drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing, a dose setting element rotatable relative to the housing during dose setting and dose dispensing, a drive member coupled to the dose setting member via a clutch, and a piston rod coupled to the housing and to the drive member Further, the device further comprises a cartridge holder removably attached to the housing and a reset element, which is permanently rotationally constrained to the housing and rotationally constrained to the drive member during dose setting, and at least one spring acting on the reset element, such that, if the cartridge holder is detached from the housing, the reset element is axially moved relative to the housing into a position in which the drive member is allowed to rotate relative to the housing

The present disclosure relates to a drive mechanism which is suitable for an injection device, especially a pen type drug delivery device and to such a drug delivery device. The mechanism comprises a spring driven rotatable drive member, a rotatable driven member, a clutch rotationally coupling the driven member and the drive member in a coupled state and allowing relative clockwise and anti-clockwise rotation between the driven member and the drive member in a decoupled state, and a spring biasing the clutch into its coupled state and allowing relative axial movement between the drive member and the driven member into the decoupled state of the clutch against the bias of the spring. The clutch comprises a first ring of crown teeth on the drive member and a second ring of corresponding crown teeth on the driven member with each crown tooth having in the clockwise and the anti-clockwise direction different ramped tooth angles such that the teeth are allowed to override each other in the de-coupled state of the clutch with a different resistance in the clockwise and the anti-clockwise direction.

A dose setting mechanism comprising a first element and a second element; the first element being moveable with respect to the second element; the first element and the second element being coupled by a ratchet mechanism allowing motion of the first element with respect to the second element from a first position to a second position only in a first direction while preventing motion in a second direction that is opposite to the first direction; once passing the second position, the first element being moveable with respect to the second element in the first direction and in the second direction.

Modules for housing electronic and electromechanical medical equipment including a system to measure and record administration of one or more IV medications or fluids for IV administration.

A syringe of the present disclosure has a hollow barrel fixedly and removeably coupled at one end to a needle and having an orifice at a second end. The hollow barrel also has a calibration inscription inscribed on an outer surface for identifying volumetric quantities of fluid being delivered within the hollow barrel, and the calibration inscription is a first color. The syringe of the present disclosure further has a plunger that has a compressible bulb coupled to an end of the plunger, and the compressible plunger has a second color that is different than the first color of the calibration inscription.

Apparatus for determining information associated with reflection characteristics of a surface comprising a sensor (60) configured to generate sensor output dependent on an intensity of light incident on the sensor and having a field of view directed at an external surface (57) in use; an illumination source (58) configured to emit light onto the external surface in use; an optically transparent window (61) located such as to allow light to pass from the illumination source to the external surface and to allow light to pass to the sensor from the external surface in use; a light concentrator (66) fixed to or integral with the window, the light concentrator being configured to concentrate at least some light from the illumination source onto the external surface in use such that the concentrated light may be reflected from the external surface onto the sensor via the window; and a processor (40) configured to use the sensor output to determine information associated with reflection characteristics of the external surface.

Apparatus comprising: a sensor configured to generate sensor output dependent on an intensity of light incident on the sensor and having a field of view directed at an external surface in use; an illumination source configured to emit light onto the external surface in use; a window located such as to allow light to pass from the illumination source to the external surface and to allow light to pass to the sensor from the external surface in use; a shield coupled to or integral with the window, the shield being substantially opaque to substantially all wavelengths of light detectable by the sensor and defining an aperture which limits the field of view of the sensor; and a processor configured to use the sensor output to determine information associated with reflection characteristics of the external surface.
