An autoinjector includes a housing and a drive chassis arranged linearly moveable within the housing. The drive chassis includes a dispensing limb and a trigger limb. The trigger limb and the dispensing limb are arranged in parallel to one another and are connected to one another at a respective distal end of the dispensing limb and the trigger limb.

A power pack for use with a medicament delivery device is presented having a plunger rod movable along a longitudinal axis; a drive spring operably connected to said plunger rod; a plunger rod sleeve arranged with holding elements for releasably holding said plunger rod with said drive spring in a tensioned state. Signal initiating elements are arranged to said plunger rod; and signal generating elements arranged to cooperate with said signal initiating elements for providing information to a user of a medicament delivery device about the movement of said plunger rod when said plunger rod sleeve has been activated to release said holding elements.

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 dial grip of an injection device comprises a grip base, an handling part provided on one side of the grip base, and clutch being provided on the other side of the grip base for releasable engagement with a dose selecting part of a dosage selection and expelling mechanism of the injection device to couple the grip base to the dosage selection and expelling mechanism for selecting and expelling a dosage with the dial grip.

Disclosed is an injection gadget corresponding to an end-effector such as a rescue robot or the like. The injection gadget is configured such that an injection needle is disposed inside an injection assembly, an injection liquid is provided between a cylinder and a piston of the injection assembly, and the piston is moved by an elastic force of a spring previously compressed inside the cylinder so that the injection needle protrudes to the outside of the injection assembly and the injection liquid is ejected, and includes a bracket that replaceably mounts the injection assembly, a main body that is connected to the bracket and includes a first body space portion of which one side surface facing the bracket and the other side surface are open to pass through each other and a second body space portion that is disposed next to the first body space portion, a controller that is mounted in the second body space portion, a linear actuator that moves a transfer shaft in accordance with a control signal of the controller, and a pusher that is disposed between the linear actuator and the injection assembly, and transmits a force of the linear actuator toward the injection assembly so that a locking pin of the bracket is deviated from locking guides of the piston of the injection assembly.

An injection device includes a housing; an actuation member movable between a first position relative to the housing and a second position relative to the housing, wherein the actuation member is arranged to inhibit a mechanical operation of the injection device when the actuation member is in the first position, and allow the mechanical operation of the injection device when the actuation member is in the second position; electronic circuitry; and an actuation sensing arrangement, wherein the actuation sensing arrangement is configured to detect movement of the actuation member from the first position relative to the housing to the second position relative to the housing, and wherein the electronic circuitry is configured to be activated in response to detection by the actuation sensing arrangement that the actuation member has moved from the first position relative to the housing to the second position relative to the housing.

A power pack for use with a medicament delivery device is presented having a plunger rod movable along a longitudinal axis; a drive spring operably connected to said plunger rod; a plunger rod sleeve arranged with holding elements for releasably holding said plunger rod with said drive spring in a tensioned state. Signal initiating elements are arranged to said plunger rod; and signal generating elements arranged to cooperate with said signal initiating elements for providing information to a user of a medicament delivery device about the movement of said plunger rod when said plunger rod sleeve has been activated to release said holding elements.

A unilateral-driven drug infusion device includes a drug storage unit, a screw, at least one driving unit, a power unit, a reset unit and an infusion tube. The drug storage unit includes a drug outlet. The screw is connected to a piston and a driving wheel provided with wheel teeth, respectively, wherein the driving wheel drives the screw to move by rotation, and push the piston provided in the drug storage unit to move forward. The driving unit cooperates with the driving wheel, wherein the driving unit includes at least one driving portion. The power unit and the reset unit are connected to the driving unit. The infusion tube includes a connection end and a subcutaneous end, and the connection end is communicated with the drug outlet and the subcutaneous end.

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.

Described herein is a dispenser for dispensing fluid that, integrated into one hand piece, comprises a variable volume chamber with a plunger disposed within the chamber and a chamber inlet and outlet. The inlet and outlet communicate directly with a common chamber volume and the plunger translates in a linear direction relative to the chamber along a common longitudinal axis to expel fluid from the chamber (expel stroke) and/or draw fluid into the chamber (drawing stroke). The plunger is linked to a controller, a power source and a motor that drives translation movement of the plunger. The dispenser described herein offers a variety of advantages over the art including accurate dosing without the user having to manually regulate the dose amount—the amount to be dosed is related to the volume of fluid in the chamber which can be pre-set or varied automatically using sensors and controllers.
