Abstract: A needle-free injector system includes a needle-free injector configured to deploy a dose of a treatment to a patient as an injection event, a gyroscope configured to monitor an orientation of the needle-free injector during the injection event, and a processor configured to perform steps of detecting that an actuator of the needle-free injector has deployed the dose in the injection event, monitoring a signal from the gyroscope during the injection event, determining an orientation of the needle-free injector during the injection event based on the signal from the gyroscope, determining whether the injection event was a treatment event including a successful delivery of the dose to the patient based on the orientation of the needle-free injector during the injection event, and transmitting information regarding the injection event to a server.

Abstract: 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.

Abstract: A needle-free injector conditionally detects a training cartridge based on the detected response to linear actuation of a plunger and enters a training mode instead of an injection mode.

Abstract: 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.

Abstract: A needle-free injector includes a housing, a cartridge positioned within the housing, and a plunger slidably coupled to and disposed within the chamber, a motor operatively coupled to the plunger, the motor operable to actuate the plunger in the chamber, and a controller operatively coupled to the motor. Methods of delivering an injectate using the needle-free injectors are provided. Methods of facilitating needle-free injection of a fluid using the needle-free injectors are also provided.
