Abstract
A device containing a temperature-sensitive material comprises a first part containing the material, a second part which engages the first part and allows, or can be disengaged or displaced to allow, the material to be dispensed or utilised, a locking means, and a temperature-sensitive activator for the locking means that is activated at a predetermined temperature, and thereby irreversibly prevents the material from being dispensed or utilised should it become frozen or exposed to temperatures below a predetermined limit.
Claims13
A device containing a freeze-sensitive liquid containing a pharmaceutical or medical product suitable for use in therapy or diagnosis, the device comprising a first part containing the freeze-sensitive liquid, a second part which engages the first part and allows, or can be disengaged or displaced to allow, the liquid to be dispensed or utilised, a locking means for irreversibly preventing the freeze-sensitive liquid from being dispensed, and a freeze-sensitive activator for the locking means, wherein the freezing of an aqueous liquid engages the locking means, whereby thawing of the aqueous liquid will not reverse the locking means.
A device containing a freeze-sensitive liquid, the device comprising:
- a compartment containing the freeze-sensitive liquid;
- a delivery system integral with the compartment comprising a mechanical structure that disperses the freeze-sensitive liquid;
- a locking mechanism that disables the delivery system;
- and
- an aqueous liquid proximate to the locking mechanism, wherein the locking mechanism is actuated by a change in a physical property of the aqueous liquid.
