Abstract
A safety device for an injection device including a protective sheath driven by a spring, the safety device being capable of taking an injection configuration in which the sheath allows an injection needle to be left uncovered, and a safe configuration in which the sheath enables the injection needle to be covered; retractable catches for retaining the spring, the retractable catches retaining the spring under stress in such a manner as to hold the safety device in the injection configuration; and deactivation mechanism for deactivating the retractable catches, enabling the safety device to take a storage configuration in which the retractable catches are not subjected to stress from the spring.
Claims11
A safety device for an injection device, wherein the safety device comprises:
- a protective sheath driven by a spring, the safety device being capable of taking an injection configuration in which the sheath allows an injection needle to be left uncovered, and a safe configuration in which the sheath enables the injection needle to be covered once an injection has been made;
- a retractable element for retaining the spring, the retractable element retaining the spring under stress in such a manner as to hold the safety device in the injection configuration;
- and
- a deactivation member for deactivating the retractable element, enabling the safety device to take a storage configuration before the injection, in which the retractable element is not subjected to stress from the spring, the member for deactivating the retractable element in the storage configuration exerting stress on the spring that is greater than the stress exerted thereon by the retractable element when in the injection configuration.
