摘要： 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.

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 active injection guide concurrently monitors surface contact and an instantaneous contact force along an injection axis of an injector in order to ensure that the injector is properly positioned on a patient before an injection can be initiated.

摘要： A method of administering subcutaneous treatment to a patient is provided. The method includes delivering, by a needle-free injection device, a first volume of a treatment at a first location on a surface of a body of the patient; detecting a movement of the needle-free injection device relative to the first location; determining, from the movement of the needle-free injection device relative to the first location, a second location of the needle-free injection device relative to the first location; determining a second volume of the treatment to deliver at the surface of the body of the patient at the second location; and delivering, by the needle-free injection device, the second volume of the treatment at the second location on the surface of the body of the patient.

摘要： A material for an injection nozzle is molded into a form that includes a sacrificial tip around the nozzle exit orifice. The sacrificial tip is then machined away using any suitable machining process to expose the exit orifice. In this manner, an injection nozzle can be fabricated with favorable geometric characteristics.
