The present disclosure refers to a system for a drug delivery device comprising a housing and a cartridge holder which may contain a cartridge filled with a medicament. The housing and the cartridge holder comprise a coding interface for dedicating a certain cartridge to a certain housing and a bayonet type attachment interface for releasably attaching the cartridge holder to the housing by an attachment movement comprising a first stage and a second stage. The system further comprises at least one compliant spring member arranged and designed such that it is strained during the first and/or the second stage of the attachment movement at least if the housing coding element does not match the holder coding element, and wherein the compliant spring member is arranged and designed to move the cartridge holder relative to the housing in a direction contrary to the attachment movement when relaxing.

A syringe for injecting liquid medicine into a body, having its needle inside said syringe liquid holding barrel, pointed at one end of the syringe barrel which rests on user's skin when injecting, which end is sealed to hold the liquid inside the barrel of said syringe by a rubber like seal, through which seal said needle's sharp tip can exit when the needle is pressed towards the body via the other end of the barrel, which needle has conduit(s) near the other end of the needle to let said liquid into the inner tube of the needle to exit via said tip when the liquid is pressured as the needle is pushed into the user's body, which syringe can be prefilled during manufacturing, so that the syringe acts as a vial too, enabling self administration upon unpacking.

An injection system and apparatus comprises a housing with a loading tray configured to accept a medication cartridge, a needle configured to transport medication from the medication cartridge to an injection site, a retractable sheath formed on an injection end of the housing, and a telescoping plunger comprising at least two telescoping sections, wherein the plunger is configured to impart downward force on the medication cartridge in order to release medication in the medication cartridge through the needle to an injection site.

The invention relates to an apparatus (2, 3), comprising a mating unit (20-1, 20-2) for releasably attaching the apparatus (2) to a medical device (1) or for releasably receiving at least a part of the medical device (1). The apparatus (2, 3) further comprises one or more optical sensors (25, 26) and/or one or more acoustical sensors (27) for determining information related to a condition and/or use of the medical device (1). The invention further relates to a system comprising such an apparatus (2, 3) and such a medical device (1), to a method (500, 600, 700) and a computer program (61) for determining information related to a condition and/or use of such a medical device (1), and to a computer-readable medium (60) storing such a computer program (61).

An apparatus (100) for use with an auto-injector configured to receive a syringe and comprising: a firing assembly (102) comprising a rearward portion (108), a plunger rod (110) moveable forward relative to the rearward portion (108) and a plunger rod driver (112) configured to drive the plunger rod (110) forward relative to the rearward portion (108); an insertion driver (106) configured to drive the syringe forwards on an insertion stroke for inserting a needle of the syringe into an injection site; and wherein the firing assembly (102) further comprises a retainer (114) engaged with the plunger rod (110) and/or the rearward portion (108) and configured to prevent forward movement of the plunger rod (110) relative to the rearward portion (108), and to disengage from the firing assembly (102) at a point on the insertion stroke.

A medicine injection pen includes a rotatable drive member and a rotary encoder associated with the drive member. The rotary encoder is configured to determine an amount of liquid medicine dispensed based on a rotational orientation of the drive member.

A device for administering needle-free subcutaneous treatment to a patient comprises an actuator configured to deliver a plurality of volumes of a treatment at a plurality of locations on a body of the patient; at least one imaging device configured to detect a movement of the needle-free device from a first location on the body of the patient to a second location on the body of the patient; and a processor configured to determine the second location on the body of the device relative to the first location from the movement of the needle-free device relative to the first location on the body, the processor further configured to determine a volume of the plurality of volumes of the treatment to deliver to the body of the patient at the second location.

An injection device for in vivo delivery of an agent includes a tubular body defining a lumen that extends along a central axis that is oriented along a longitudinal direction. A distal end of the lumen is occluded and the tubular body defines at least one side-port extending from the lumen to an outer surface of the tubular body. The at least one side-port is elongated along the outer surface of the tubular body.
