Problems solved by technology

[0006] WO 2005 / 056089 discloses a heating device for rigid containers of fluids, but the housing has very thick walls making it heavy and bulky, and it requires an external energy supply for heating
It is therefore totally unsuitable for veterinary use where portability is critical

Embodiment Construction

[0030] Such as figure 1 As shown, the device 1 comprises a housing 2 having a removable cover 3 which together defines a protective chamber 4 .

[0031] image 3 and 4 One embodiment of housing 2 is best shown. The housing 2 preferably comprises a hollow cylindrical body 20 with a removable cover 3 . The cap 3 defines a central opening 10 for access to a vial contained within the housing (as further described below). The main body 20 and lid 3 are preferably removably connected to each other by threads, although hinges or other connecting means may be used. The bottom of the body 20 includes a web defining the aperture 15 .

[0032] Said housing 2 is preferably made of a hard but light material, such as plastic, in particular high density polyethylene. To accommodate a conventional 500ml vial having a diameter of approximately 7.5 cm and a height of 18.5 cm, a typical housing 2 may have an external diameter of approximately 11 cm and a height including the cap of approxi...

Abstract

A heating device (1) is described for a container (7) of a liquid pharmaceutical product having a viscosity of 50-500 cP at 4 DEG C and contained within a glass container. The device (1) comprises a substantially rigid, thin-walled housing (2) defining an openable chamber for receiving the container (7), a heat source (6) in the chamber comprising a hermetically sealed package containing a super-cooled metal salt fluid or liquid and an actuator (14) for activating the super-cooled metal salt to produce heat, wherein the ratio of the volume of the metal salt to the intended volume of the product is no more than 1:1.

Description

field of invention [0001] The present invention relates to devices suitable for heating liquid pharmaceuticals administered to animals, especially parenteral pharmaceuticals, ideally administered at a temperature close to room temperature (approximately 25°C). Background of the invention [0002] It is often necessary to heat liquid drug products (referred to herein as "products") prior to administration in order to increase the solubility of the active ingredients in these products. With particular reference to parenteral products, especially veterinary parenteral products, heating will also reduce the likelihood of systemic cold shock in the patient due to administration of the product. [0003] These products may often be applied in remote, exposed and cold environments, such as on pasture where animals need to be treated. Heating or re-solubilization of the product ingredients is therefore typically achieved by shaking and rolling between the user's hands or even by usi...
