A medicine injection pen includes a body, a drive member within the body and configured to move relative thereto upon actuation, a cartridge housing releasably engageable with the body and configured to retain a medicine cartridge, at least one sensor, and at least one detector. The medicine cartridge has a liquid medicine therein and includes a piston configured to slide therein. The drive member is configured to move relative to the body to urge the piston to slide within the medicine cartridge to dispense at least some of the liquid medicine from the medicine cartridge. The sensor(s) is configured to sense movement of the drive member relative to the body to enable determination of an amount of the liquid medicine dispensed. The detector(s) is configured to detect a gap between the drive member and the piston.

A device for dispensing a controlled amount of a fluid from a syringe, the syringe having a plunger extending along a linear axis through a syringe flange and into a syringe barrel. The device includes a housing to accommodate at least a portion of the syringe, and a drive wheel attached to the housing to contact a side of the plunger, the housing to press the drive wheel into the side of the plunger between the syringe flange and an end of the plunger.

The present invention provides a method for treating a disease or condition in a subject, comprising administering to the subject's skin a composition comprising an effective amount of one or more cannabinoids, wherein the composition is administered with a microneedle delivery device.

An injector has a cartridge door movable between a fully closed position and a fully open position. A power supply is employed to power at least one power-operated component of the injector. A power supply circuit electrically connects the power supply with the at least one power-operated component. An electrically insulated arm is movable from a first state, in which the electrically insulated arm electrically disconnects the power supply from the circuit, to a second state, in which the electrically insulated arm connects the power supply with the circuit to provide power to the at least one power-operated component. The insulated arm is coupled to the cartridge door and initially positioned in the first state thereof in the fully closed position of the cartridge door, whereby movement of the cartridge door out of the fully closed position toward the fully open position moves the arm to the second state thereof.

Systems, devices, and techniques are disclosed for administering and tracking medicine to patients and providing health management capabilities for patients and caregivers. In some aspects, a system includes an injection pen device in communication with a mobile communication device having a software application to determine a recommended dose based on prior dose data, analyte data, and nutrient data and to generate a report illustrative of a relationship between the medicine data, the health data, and the contextual data.

A smart drug injection device is disclosed, comprising a main body, a circuit board, a display, a syringe and a transmission mechanism; the main body comprises an accommodating space and a power button; the circuit board comprises a control unit and a storage unit; the transmission mechanism comprises a motor, a screw rod, a propelling block and a movable clamp, with the control unit electrically connected to the storage unit, the power button, the motor and the display, the motor connected to the screw rod, the propelling block movably arranged on the screw rod, the movable clamp disposed at one end of the propelling block and movable between two positions; the syringe is on one side of the main body and comprises a cylinder and a needle holder, one end of the cylinder has a needle and the other end is assembled with the needle holder.

A medicament delivery device is presented having a front-end device with a front-end housing and a delivery member cover that moves along a longitudinal axis between an extended position and a retracted position relative to the front-end housing, and a medicament container holder arranged in the front-end housing that receives a medicament container; and a reusable base device that is detachably connected to the front-end device, the base device has a plunger, a motor to drive the plunger inside the front-end housing, and wherein the motor drives the plunger from a second end position back to an initial end position, and a motor switch having a first switch position that changes to a default switch position by displacement of the delivery member cover when the delivery member cover is moved back from a retracted position to an extended position causing the motor to rotate in a reverse direction and drive the plunger from the second end position to the initial end position.

Apparatus and methods for delivering medicament to a patient. The apparatus may include elements with different capacities to attenuate or absorb sterilizing radiation. The apparatus may include a medicament delivery assembly with interactive elements for dose-setting, priming and medicament ejection. The assembly may include a chamber housing a radiation-sensitive medicament present in the apparatus during sterilization by electron beam. The assembly may include an actuator chassis, a drive mechanism, a needle-priming mechanism and a fluid-displacement mechanism including a fluid-displacement member. The chassis may be fixed, relative to an outlet, to the chamber. The member may be slidingly and/or threadingly engaged with the chassis, and may be configured to move relative to the outlet to deliver the medicament through the outlet. Assembly elements may be nested coaxially and/or stacked axially. The assembly may include at least one hollow region. The hollow region may reduce beam attenuation or reduce radiation absorption.

A computer-controlled injector for use with a medicament cartridge and including a housing having a medicament cartridge receiving volume and a medicament cartridge insertion and removal opening communicating with the medicament cartridge receiving volume; a pivot mount element mounted onto the housing for selectably enabling access to the medicament cartridge receiving volume via the opening; a mechanical latch selectably locking the pivot mount element in a closed operative orientation; and an injection drive mechanism including a computer-controlled motor for driving a piston, forming part of the medicament cartridge, for injecting a medicament, the computer-controlled motor also being operative for operating the mechanical latch.

An injector includes an injector housing, an activation button assembly translatable from an unactuated position to an actuated position and a cartridge door movably mounted to the injector housing between an open position and a closed position. A deflectable interference member has a resting position configured to limit an insertion depth of a cartridge into an interior channel of the cartridge door to a sealed position, wherein the cartridge piercing needle does not fully penetrate a pierceable septum of the cartridge. Movement of the activation button assembly from the unactuated position to the actuated position thereof, in the closed position of the cartridge door, deflects the interference element out of the resting position thereof, thereby enabling further advancement of the cartridge into the interior channel of the cartridge door to an unsealed position, wherein the cartridge piercing needle fully penetrates the pierceable septum.
