DEVICE FOR HEATING A PHARMACEUTICAL USING A SUPER-COOLED METAL SALT SOLUTION

摘要

A heating device (1) for a container (7) of a liquid pharmaceutical product having a viscosity of 50-500 cP at 4°C. The device comprises a substantially rigid, thin-walled housing (2) defining an openable chamber for receiving the container (7) and a heat source (6) within the chamber. The heat source comprises a hermetically sealed package containing a super-cooled metal salt fluid or liquid solution and an actuator (14) for activating the heat source to produce heat in an exothermic crystallisation of the metal salt. The ratio of the volume of the metal salt heat source to the intended volume of the pharmaceutical product is no more than 1:1. The heating device can be attached to a support frame and worn on the users back or shoulders.
