Systems and methods are disclosed for processing sensor data collected by a drug delivery device with an external computing device. The drug delivery device may include a reservoir and a delivery cannula having a proximal end in fluid communication with the reservoir and a distal end to be received within a patient. The drug delivery device may further include one or more sensors configured to generate sensor data representative of a condition and/or operational state of the drug delivery device, and a communication module configured to transmit information to the external computing device. The external computing device may process the information received from the drug delivery device according to information stored in a memory of the external computing device to determine the condition or the operational state of the drug delivery device and/or generate instructional or informational prompts to be displayed to a user or patient.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A first guide path, a second guide path and a third guide path may be disposed on the housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The retractable sheath also may have a guide element. The first, second and third guide paths are configured to slidingly receive the guide element. The device also having a first locking member, a second locking member, a rotating cam disposed in the housing body, and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection.

The present invention relates to a signal delaying assembly for a medicament delivery device, said assembly comprising a delay female member containing a fluid, a delay male member having at least one passage, a delay unit connected to the delay female member or to the delay male member, wherein a relative movement between the male member and the female member and towards each other causes the transfer of said fluid from said female member through the at least one passage for slowing said movement, characterized in that the delay unit is releasably connected to a signal generating assembly for delaying at least one feedback signal.

A jet injector that includes a prefilled syringe. The syringe includes a fluid chamber that contains a medicament. The syringe also has an injection-assisting needle, and a plunger is movable within the fluid chamber. A housing is configured for allowing insertion of the needle to a penetration depth. The housing includes a retractable guard and an interference component, e.g., a lock ring, adjacent to the retractable guard that interferes with the movement of the retractable guard. An energy source is configured for biasing the plunger to produce an injecting pressure to jet inject the medicament from the fluid chamber through the needle to an injection site.

A syringe cover obscures a patient's observation of needle insertions for medical procedures. Obscuring the needle insertion from the patient reduces the psychological fear associated with needles. The syringe cover includes a tubular sleeve, a collapsible sleeve, and a viewport opening. The tubular sleeve covers the fluid reservoir barrel to hide the fluid drawn from or injected into the patient from the patient's view. The collapsible sleeve obscures the needle of the syringe from the patient's view. The collapsible sleeve is pressed against the patient's body when the needle penetrates the patient's skin. The collapsible sleeve deforms as the needle is inserted into the patient's body such that the collapsible sleeve does not obstruct the insertion of the needle. The viewport allows the medical practitioner to view the volume of fluid within the fluid reservoir barrel of the syringe.

An injection device (100), including a base (104), a sliding body (116) slidably connected to the base (104), a double-ended needle (120) fixed to the sliding body (116), a biasing member (124) for proximally biasing the sliding body (116) with respect to the base (104), and for retracting the needle (120) into the device (100) subsequent to activation of the device (100), a medicament cartridge (128) for holding a medicament, slidably connected to the sliding body (116), and a stopper (132) slidably disposed within the medicament cartridge (128). The base (104) has a proximal end (108) and a surface (164) disposed at a distal end (112) thereof for contacting a patient's skin. The base (104) also has a first locking mechanism. The sliding body, (116) has a locking feature and a second locking mechanism. The second locking mechanism locks the medicament cartridge (128) relative to the sliding body (116) upon completion of displacement of the medicament cartridge (128) relative to the sliding body (116). The first locking mechanism and the locking feature interact to lock the sliding member (116) relative to the base subsequent to retraction of the needle (120) into the device (100).

An automatic needle device comprises a body into which a needle assembly and needle are mounted. The device also includes a needle guard to cover the needle until it is used and to lock over the needle after use so the needle is not re-exposed. The locking is accomplished with a coil spring action locking device. A container for holding the automatic needle device also facilitates the viewing of the distal end of the needle prior to use on a patient.

A device for administering a fluid medicament by injection comprises a dosing portion (1) with a collapsible reservoir (10). The reservoir (10) has a maximum volume in an extended state and a minimum volume in a collapsed state. Prior to injection, the reservoir (10) is in the extended state and contains a liquid to be administered, and the reservoir (10) is biased towards the collapsed state. The device further comprises a needle (2), wherein a lumen (20) of the needle (2) is in fluid communication with the reservoir (10). The device further comprises a shield portion (3) with a plug (30). Prior to injection, the shield portion (3) is in a deployed position where the plug (30) blocks the lumen (20) of the needle (2). The shield portion (3) is adapted to move in response to an actuation force from the deployed position to a retracted position where the lumen (20) of the needle (2) is open, thereby causing the reservoir (10) to shift to the collapsed state to expel the liquid through the needle.

Drug delivery systems, devices and methods of use for recording a drug dose completion signal in a data management system are provided. Aspects of the invention include drug delivery systems comprising a syringe stopper rod that comprises a sensor component comprising a wireless transmitter module and an activation component configured to activate the sensor component when the syringe stopper rod has completed a delivery stroke, wherein the wireless transmitter module is configured to transmit a report comprising a drug dose completion signal when the sensor component is activated.

The present invention relates to medicament injection devices (100). A cartridge (600) with a septum and a needle unit (500) having front and rear needles (510, 520) are configured for relative movement from a state where the septum is sealed to a state where the septum is pierced by the rear needle (520). The injection device (100) may include a needle shield (350) and be configured for piercing the septum by the rear needle (520) when the front needle (510) is operated relative to the needle shield (350). The injection device (100) may also include a damping mechanism configured for limiting the speed of movement of the cartridge relative to the needle unit. The injection device (100) may also include an indicator generating a signal when a piston driver has travelled the complete stroke length, wherein the indicator has a deflection element that is deflected prior to or during movement of the cartridge relative to the housing.
