According to an embodiment, a painless syringe with an anti-slip structure for perforating an alveolar bone and injecting an anesthetic comprises an injecting part having a needle for perforating the alveolar bone and injecting the anesthetic, a holder having a first end coupled with the injecting part and a second end open and empty, an ampoule formed to be inserted into the holder and having a first end into which the needle of the injecting part is inserted and a second end having a piston for discharging the anesthetic, a housing formed to receive the holder and having a through hole to expose the first end of the holder to an outside, and a handpiece coupled with the housing, rotating the ampoule, the holder, and the injecting part to perforate the alveolar bone, and pressing the piston to inject the anesthetic.

A multi-cartridge injector includes a plunger having a main brace and a pair of stems, each of the pair of stems having a coupler, a pair of stoppers coupled to each coupler of the pair of stems, a containment unit having a pair of barrels, and a Y-shaped conduit having a pair of branches and a common shaft, and a passageway that extends through the common shaft and the pair of branches, each of the pair of branches being in communication with an interior of one of the pair of barrels.

A syringe holder for an autoinjector is presented having a tubular body extending around an axis in a circumferential direction and along the axis in an axial direction, the tubular body having a cut-out extending from a distal end of the tubular body and a flexible expansion joint extending across the cut-out in the circumferential direction. The tubular body can also have an inner surface and an outer surface, a first cut-out in the tubular body, the first cut-out extending in an axial direction from a proximal end of the tubular body and either a recess in the inner surface of the tubular body, the recess extending in the axial direction from the distal end of the tubular body, or a second cut-out in the tubular body, the second cut-out extending in the axial direction from a distal end of the tubular body.

An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation.

An electronically-controlled capturing system for capturing data representing an amount of a drug expelled or discharged from a drug reservoir includes an electronic circuit including an electric energy unit, a processing unit operable by electric power obtained from the electric energy unit and operable to acquire data, and an electronic storage unit connected to the processing unit and configured to store the acquired data. The processing unit is operable to write the acquired data in the storage unit and is operable to read and provide the stored data from the electronic storage unit. The capturing system also includes a data reading disabling unit operably connected to the processing unit , the electronic storage unit and/or the electric energy unit. The data reading disabling unit is switchable into an activated state, in which the data reading disabling unit persistently prevents readout or providing of stored data from the electronic storage unit.

The present disclosure relates to an injection head of a needleless syringe, needleless syringe body, and needleless syringe. The injection head includes a medicine barrel and a piston rod. The medicine barrel opens at a rear end and has an injection micropore at a front end. A piston of a piston rod is movable within a chamber in an front-rear direction, the piston and a sidewall and a front wall of the medicine barrel jointly define a medicine liquid receiving chamber. The piston rod is provided therein with a medicine liquid channel. The injection head and the vial can be mounted together on the needleless syringe body, the medicine liquid can flow via the medicine liquid channel into the medicine liquid chamber, and the piston rod can eject medicine liquid within the medicine liquid receiving chamber outside via the injection micropore. According to the solution of the present disclosure, a vial, such as a cartridge vial and the like, can be received within a needleless syringe body, and medicine suctioning and injection can be completed efficiently and effortlessly during each use, where there is no need for removing the vial or separating the medicine barrel from the vial.

A device for injecting a medicament is provided. The device has a housing with a container within it which can hold a medicament. At its proximal end the container has a needle and a stopper. The device includes a plunger which at one end can engage the stopper. At the opposite end, the plunger can engage a first resilient member to move the stopper within the container to inject the medicament from the container. The device includes a collar with distal and proximal ends, the distal end engaging with a carriage and causing its rotation and the proximal end engaging with a second resilient member. The second resilient member can engage with a skin sensor which has distal and proximal ends. At the proximal end, the skin sensor can contact an injection site. The housing has a cap which can reduce or prevent movement of the skin sensor.

The present invention is directed to a pen-type injector equipped with a cartridge holder for a drug delivery device. The cartridge holder has a longitudinal axis and comprises a body for receiving a cartridge, wherein the body comprises at a proximal end engagement means for releasably coupling the cartridge holder to the drug delivery device, a latch member for releasably engaging a cap of the drug delivery device and an alignment element which is visual from the outer side of the body. The alignment element may be an aperture provided in the body and/or a lug which forms the latch member.

The present disclosure refers to a housing element for a drug delivery device. The housing element comprises longitudinal axis and defines an interior space for receiving components of a drive mechanism of the drug delivery device and at least a portion of a cartridge of the drug delivery device. The housing element comprises an engagement feature for axially constraining the housing element to a cartridge holder of the drug delivery device. In order to constrain the cartridge in the housing element, it further comprises at least one crush web protruding radially inwards into the interior space. The at least one crush web is angled relative to the longitudinal axis of the housing element by at least 3° such that when the cartridge is introduced into the interior space the at least one crush web folds radially outwards.

A syringe has an injection mechanism configured to be detachably connected to a medicine vial. The injection mechanism can be manually triggered to convert an injection mode and a standby mode; the injection mechanism has a housing, a spiral pushing assembly, a metering guide sleeve, a total volume control nut, a diagonal tension knob, and a metering screw; after the medicament liquid in the medicine vial is used up, a user can remove the medicine vial, the injection mechanism can be converted into the standby mode, and non-return ratchet buckles of the metering guide sleeve can be disengaged from a one-way ratchet portion of the housing; thus, the metering screw can be pushed back to an original position, and the total volume control nut is pushed back to an initial full volume position of the metering guide sleeve, so that the syringe can be reused.
