Disclosed herein are techniques related to safeguards against usage of incorrect portable medicine delivery devices. Such techniques may be practiced for a plurality of portable medicine delivery devices that include a first device and a second device. The techniques may involve obtaining usage data indicative of the first device being manipulated in preparation for medicine delivery. The techniques may further involve determining, based on the usage data, that the first device is mistakenly being manipulated instead of the second device. The technique may also involve, responsive to determining that the first device is mistakenly being manipulated, generating a message to prevent medicine delivery by the first device.

Disclosed is a fluid injection device for a needle free syringe is provided that is spring-loadable and comprises a trigger positioned within the housing and actuated by depression of a push-button disposed opposite the dispensing end at an external actuation surface disposed transverse to the injection axis. The trigger has a trigger latch configured to release a trigger catch as heaving part of the spring-loaded piston of the device. The trigger catch is configured to urge the trigger latch in a direction transverse to the injection axis when the piston moves from the unloaded position to the loaded position. The compression spring is retained around the piston and retained within the housing by a piston head. The device further comprises a syringe adapter and a safety cap which prevents accidental triggering.

Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a housing, a container, a trigger member, and an interlock assembly. The trigger member may be selectively moveable relative to the housing to activate operation of at least one activatable element of the drug delivery device. The interlock assembly may include a lever mounted rotatably relative to the housing, a proximity sensor moveable between a first position extending beyond an exterior surface of the housing and a second position retracted toward the housing, and a rotational biasing member operably connected to the proximity sensor via the lever. When the proximity sensor is in the first position, the interlock assembly may limit movement of the trigger member relative to the housing. The rotational biasing member may be configured to exert a torque biasing the proximity sensor toward the first sensor position.

The application describes lock mechanisms for medicament delivery devices. The lock mechanisms extend from a proximal end to a distal end in an axial direction relative to a longitudinal axis, the lock mechanisms can have a housing, a medicament delivery member guard and a cap. The lock mechanisms can also include a protrusion extending in a radial direction relative to the longitudinal axis and a recess or cut-out. Various related medicament delivery devices, medicament delivery device components, sub-assemblies and methods are also described.

The application describes a medicament delivery member guard lock assembly for a medicament delivery device, the medicament delivery member guard lock assembly includes a housing having a recess or a slit; a medicament delivery member guard slidably arranged in the housing, the medicament delivery member guard extending from a proximal end to a distal end; a lock activation sleeve slidably arranged in the housing at the distal end of the medicament delivery member guard; and a medicament delivery member guard lock arranged in the housing adjacent to the lock activation sleeve, wherein the medicament delivery member guard lock has a flexible arm pivotally attached to a base, wherein the flexible arm has a proximal part, a distal part and is attached to the base between the proximal part and the distal part, and wherein the proximal part of the flexible arm is arranged adjacent to the recess or slit in the housing.

A needle-based device includes a barrel as a body thereof and a needle. A portion of the needle is received within the barrel and glued thereinto to cause the needle to protrude from the barrel. The needle-based device also includes a needle shield to protect an entire length of the needle protruding from the barrel based on completely encompassing the entire protruding length of the needle in a first state of disuse of the needle-based device. The barrel includes wings on lateral sides of an outer wall thereof. The wings extend perpendicular to a length of the barrel to couple the needle shield to the barrel in the first state of disuse of the needle-based device.

A method includes protecting an entire length of a needle of a needle-based device protruding from a needle mount or a body of the needle-based device in a first state of disuse thereof based on providing a needle shield encompassing the entire protruding length of the needle, and encompassing the needle shield completely in the first state of disuse with an external cap. The method also includes providing a guide element protruding inward from an end of the external cap farthest away from the needle mount or the body of the needle-based device, internal to the external cap parallel to a length of the external cap and through the needle shield such that, in the state of disuse, the guide element at least partially envelops the needle therewithin to prevent significant lateral movement of the needle and prevents the end of the external cap from touching the needle.

A method and device for delivering medications that includes a syringe body, a cartridge nest with an application tip, a plunger actuator, and an electronic lock subassembly adapted for preventing administration of the medication until specific conditions are met. The medicine cartridge may comprise a form of a digital security key to prevent the device from administering medication unless specific configurations and conditions are met. The device may further be adapted with pre-programmed information and may be used with a smartphone, tablet, or computer application. The electronic lock subassembly will only permit the administration of medicine when the patient and/or administrator is verified via facial and voice recognition, biometric identifier, or other unique information. Upon proper permission, the device may be used to administer medicine, including injecting medicine into the nasal cavity of a patient.

The present disclosure related to an apparatus that may be used for taking blood glucose measurements and providing individualized insulin dose recommendations wherein the apparatus is easy to use and facilitates improved diabetes control in patients. Also disclosed are related methods.

An injection device for the self-administration of an injection of solution that includes a body portion/handle configured for engagement with a cartridge containing the solution and an injection needle. The injection device includes a safety mechanism whereby ejection of solution from the injection device cannot be done unless the safety mechanism is released. The injection device further involves two-stage deployment whereby a needle may be inserted upon release of the safety mechanism and solution is injected upon full insertion of the needle.
