An injection device includes a carrier, a needle, a driver coupled to the needle, the driver being slidable relative to the carrier between a retracted configuration and a deployed configuration, a shuttle configured to move the driver between the retracted configuration and the deployed configuration, and a stop configured to move from a first configuration to a second configuration, wherein the stop is configured to maintain the driver in the deployed configuration, and movement of the stop from the first configuration to the second configuration allows the shuttle to move the driver from the deployed configuration to the retracted configuration.

Techniques for artificial intelligence medicament or test delivery device sound output (MDDSO) detection includes receiving, at a neural network, processed data based on operational data that indicates a time series having a first duration for signals from a vibration detector collected during operation of a medicament device. The neural network classifies the processed data as a first MDDSO or not. The classificatio n data is sent to an output device. The neural network has been trained, prior to receiving the operational data, with first training data and second training data. The first training data indicates time series of ambient sounds, each time series having the first duration. The second training data indicates time series of sound having the first duration during operation of the type of medicament or test device, wherein each time series of the second training data includes sound from the first MDD SO emitted from the device.

A transdermal injection component, comprising: an injection volume configured to contain an injectable treatment therein, a plunger, the injection volume being in fluid communication with at least one orifice such that the plunger is configured to exert the injectable treatment from the injection volume through the at least one orifice; the plunger sealably engaged with the injection volume, the plunger configured to exert the injectable treatment from the injection volume through the at least one orifice so as to effect transdermal injection of the injectable treatment to a patient; the transdermal injection component being configured to engage with an actuator device configured to effect movement of the plunger to exert the injectable treatment through the at least one orifice.

An autoinjector housing includes a cylindrical case enclosing an interior space capable of accommodating an autoinjector mechanism, a cylindrical cap removably attachable to the cylindrical case, and optionally a cylindrical overmolding. An exterior cross-sectional shape of the cylindrical case is oblong along at least a portion of its axis. An exterior cross-sectional shape of the cylindrical cap may be varied along its axis such that there is a gradual decrease in cross-sectional area from an open end toward a closed end and a step-up in cross-sectional area approaching the closed end. An end of the cylindrical case may be covered by the cylindrical overmolding, which may have non-uniform radial thickness and may be made of a material having elasticity.

An example system for therapy delivery includes one or more processors configured to in response to a prediction indicating that the meal event is to occur, output instructions to an insulin delivery device to deliver a partial therapy dosage, to a device to notify the patient to use the insulin delivery device to take the partial therapy dosage, or to the insulin delivery device to prepare the partial therapy dosage prior to the meal event occurring, and in response to a determination indicating that the meal event is occurring (e.g., based on movement characteristics of a patient arm), output instructions to the insulin delivery device to deliver a remaining therapy dosage, to the device to notify the patient to use the insulin delivery device to take the remaining therapy dosage, or to the insulin delivery device to prepare the remaining therapy dosage.

Provided herein is a system for homogeneous injection of medicine including a device for homogeneous injection of medicine, which may include a cylinder holding part having a cylinder of a syringe held therein, a plunger resting part being configured to be independent from the cylinder holding part and having an end of the plunger of the syringe rest therein, first and second pressurized lead screw supporting parts each being provided on one side of the cylinder holding part and one side of the plunger resting part, respectively, and being connected to a pressurized lead screw being provided with a screw thread, and a motor being connected to one side of the first pressurized lead screw supporting part so as to rotate the pressurized lead screw; and a monitoring unit monitoring injection dosage and having one side connected to a needle of the syringe or a medicine outlet of the syringe cylinder and having its opposite side connected to a tube providing medicine to a patient, thereby monitoring physical quantities related to the injection of the medicine.

A sub-assembly of a medicament delivery device is presented, where the sub-assembly includes a plunger rod that is biased, a main body arranged on the plunger rod, and a coupling member movable relative to the main body, where the main body includes a first locking element, the coupling member includes a second locking element, and where the first locking element and the second locking element are configured to be releasably engaged with each other such that the coupling member is prevented from moving relative to the main body.

A method for needle-free injection and a needle-free injector device are provided. The method includes automatically injecting an injectable into a surface in contact with the needle-free injector in response to a skin compression parameter of an end of the needle-free injector. A needle-free injector device (102) includes predefined structures formed on it to inject an injectable through a non-porous material. The predefined structures engage an airlock mechanism such that an airlock in the non-porous material and operably coupled to the airlock mechanism can only be opened and closed to enable needle-free injection through the non-porous material without disrupting an integrity of the non-porous material by the needle-free injector device. Other functions, embodiments and methods for using and programming the needle-free injector device are also provided.
