The disclosed sleeve according to various aspects of the present technology may comprise a tubular body adapted to be fitted around a barrel of an injection gun. The tubular body may comprise an interior surface and an exterior surface. The interior surface may define a cavity in the tubular body for receiving the barrel of the injection gun, wherein the interior surface may be configured to enclose the barrel of the injection gun. The exterior surface may comprise at least one marking formed thereon. The sleeve may also comprise an open first end terminating in a first peripheral annular edge and an open second end opposite the open first end and terminating in a second peripheral annular edge.

A drug delivery pump includes a dosing chamber (16) for delivering a substance (18) therefrom, pushing apparatus, and a thermal energy source (14) arranged to cause a sufficient change in temperature in a portion of the pushing apparatus so that the pushing apparatus imparts a pushing force against the substance to cause the substance to be delivered from the dosing chamber. A controller (90) controls delivery of the substance from the dosing chamber. A thermal insulator (24) thermally insulates the substance in the dosing chamber from the thermal energy source.

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.
