摘要： An apparatus for use in injectate delivery includes an actuator including a linkage, a force generating mechanism mechanically coupled to the linkage, and a controller coupled to the force generating mechanism. The force generating mechanism includes a passive force generator and an active force generator. In operation and on the basis of a control signal, the controller is configured to control the force generating mechanism to provide an input force to the linkage that is a combination of the first force provided by the passive force generator and a second force provided by the active force generator.

摘要： An apparatus for injectate delivery includes a cartridge, a linear actuator, a rotary motor mechanically coupled the actuator, and a controller coupled to the motor. The controller controls a linear motion of the actuator by controlling an electrical input supplied to the motor in a first interval during which the motor is stationary with the linear actuator engaged with the cartridge to displace an injectate in the cartridge, a second interval following the first interval during which the controller accelerates the motor from stationary to a first speed selected to create a jet of the injectate from the cartridge with a velocity sufficient to pierce human tissue to a subcutaneous depth, a third interval during which the controller maintains the motor at or above the first speed, and a fourth interval during which the controller decelerates the motor to a second speed to deliver the injectate at the subcutaneous depth.

摘要： An injection device for use with a cartridge containing an injectate includes a housing. The housing includes an end wall at its distal end and an inner wall. The inner wall extends in a direction from the proximal end of the housing to the distal end of the housing and separates a first chamber from a second chamber in the housing. The housing includes a first opening disposed in the end wall and is in fluid communication with the first chamber. The housing includes a second opening is in fluid communication with the second chamber. A coupler is disposed in the first chamber for coupling to the cartridge. The first opening and the second opening are in fluid communication via a channel for transfer of fluid between the first chamber and the second chamber.

摘要： An adapter for use with an injection device includes a first end, a second end and a first longitudinal axis extending from the first end and the second end. The adapter also includes a chamber defined by a sidewall between the first end and second end and a nozzle having a passageway extending through the sidewall, the passageway having an input at the chamber, an output at an outer surface of the body and a passageway axis extending from the input to the output, the passageway axis being angularly offset from the longitudinal axis of the channel. A cartridge can include such an adapter.

摘要： An injector cartridge is configured for sterile storage and transfer of a fluid in a pre-filled syringe. The injector cartridge includes a first housing section and a second housing section and is configured to move the pre-filled syringe from a sterile storage position to a fluid transfer position upon linear displacement of the first housing section relative to the second housing section.

摘要： An apparatus for transdermal injection includes a sleeve including a proximal end, a distal end, and an inner wall surface extending along the sleeve from a first opening at the proximal end to a second opening at the distal end. The inner wall surface forms a channel in the sleeve, the channel having a first portion with a substantially frustoconical shape. The channel of the sleeve is configured to receive a substantially frustconically shaped injection cartridge, to substantially uniformly support the injection cartridge during a transdermal injection operation, and to prevent movement of the injection cartridge out of the distal end of the sleeve.
