A medical device comprising a multilayer printed circuit board (PCB) comprising a heating element on an inner layer of the PCB; a single cell electrical power source to power the heating element; and a chamber adapted to contain a liquid, at least part of said chamber being defined by a thermally conductive material configured to provide a thermal transfer interface between the chamber and the PCB.

Heaters for medical devices

The invention provides in one aspect a drug delivery device comprising a drug container assembly containing a drug, and a plunger positioned within the container assembly, the drug container assembly having an outlet for dispensing the drug, wherein, in an initial position, the outlet is sealed; a drive mechanism comprising a first stored energy source operable to apply pressure on the plunger or the drug container to pressurise the drug, and a first release mechanism operable to unseal the outlet after the drug has been pressurised. In another aspect, there is provided a drug delivery device comprising a housing, including an external housing portion configured to be held in use and a drug containing portion containing a drug, a needle assembly comprising a needle fixed to a needle hub, the needle hub configured to move relative to the drug containing portion from an initial position within the housing to an insertion position in which the needle extends beyond the housing, a first stored energy source configured to move the needle hub from the initial position to the insertion position, and a plunger within the housing and configured to move relative to the drug containing portion to eject the drug through the needle when the needle is in the insertion position.

Automatic drug delivery devices

Diagnostic test device

There is provided drug delivery devices comprising a drug container assembly with a needle and automatic needle insertion and drug delivery mechanisms. Aspects of the devices described include a noise-generation mechanism to indicate the completion of drug delivery, a mechanism for triggering drug delivery following needle insertion, front-end activation of the device and a safety mechanism for covering the needle after use and methods of assembly of the devices.

Drug delivery device

There is provided an electronically controlled, motor-driven, breath actuated metered dose inhaler for delivering aerosolized medicament or other matter to a user. The inhaler may comprise a base housing including a motor-driven actuator and other system components and a removable aerosol cartridge insertably receivable in the base housing. The inhaler may be paired with a smart phone or other client computing device to provide additional functionality, such as to provide instructional information and feedback regarding usage of the inhaler, to generate and display dosage tracking information, and to provide alerts and reminders to a user of the inhaler or others.

Aerosol delivery systems

A pre-filled drug delivery device, comprising a housing, a drug container within the housing and containing a drug; a plunger held within the drug container, movement of the plunger within the drug container being operative to dispense the drug from the drug container through an outlet; and a drive mechanism within the housing including a stored energy source and a plunger rod held in locked position against the stored energy source prior to activation of the device, wherein on activation of the device the stored energy source moves the plunger rod such that the plunger rod moves the plunger within the housing wherein the plunger rod comprises a longitudinal shaft formed from sheet metal, wherein the sheet metal defines a plane, and wherein the sheet metal is deformed so that the longitudinal shaft comprises an out-of-plane engagement surface, the out-of-plane engagement surface configured to engage a retaining surface on the housing or on a component of the drive mechanism, to hold the plunger rod in the locked position.

Drug delivery device with pressed metal plunger rod

The invention provides in one aspect a drug delivery device comprising a drug container (), and a plunger () positioned within the container assembly, the drug container assembly having an outlet for dispensing the drug, wherein, in an initial position, the outlet is sealed; a drive mechanism comprising a first stored energy source () operable to apply pressure on the plunger or the drug container to pressurize the drug, and a first release mechanism operable to unseal the outlet after the drug has been pressurized. In another aspect, there is provided a drug delivery device comprising a housing, including an external housing portion configured to be held in use and a drug containing portion containing a drug, a needle assembly comprising a needle fixed to a needle hub, the needle hub configured to move relative to the drug containing portion from an initial position within the housing to an insertion position in which the needle extends beyond the housing, a first stored energy source configured to move the needle hub from the initial position to the insertion position, and a plunger within the housing and configured to move relative to the drug containing portion to eject the drug through the needle when the needle is in the insertion position.

There is provided drug delivery devices including a drug container assembly with a needle and automatic needle insertion and drug delivery mechanisms. Aspects of the devices described include a noise-generation mechanism to indicate the completion of drug delivery, a mechanism for triggering drug delivery following needle insertion, front-end activation of the device and a safety mechanism for covering the needle after use and methods of assembly of the devices.
