Abstract: A device for dispensing liquid contained in a container, the device including an elastomer element that can take up: a liquid release position allowing liquid to flow out of the device; and a non-return position preventing liquid from flowing back into the device; the device further including a bearing mechanism against the elastomer element in register with a recessed zone, serving to deform the elastomer element in its non-return position.

Abstract: A fluid dispenser device including a pump for dispensing the fluid; a first arm referred to as the “main” arm, mounted to pivot on the device about an axis referred to as the “main” axis, which arm has a press zone on which the user exerts pressure in order to actuate the pump; and a second arm, referred to as the “intermediate” arm, mounted to pivot on the main arm about an axis, referred to as the “intermediate” axis, this axis being disposed on the main arm between the press zone and the main axis, and the intermediate arm being configured to transmit the movement of the press zone to the pump.

Abstract: A device for delivering a substance, the device including a first stationary portion and a second movable portion that is movable relative to the first portion between a rest position and an activated position, the device further including an abutment for putting the movable portion into abutment relative to the stationary portion, which abutment needs to be forced past in order to enable the movable portion to go from its rest position to its activated position, the abutment carried by the movable portion and an abutment carried by the stationary portion, at least one of these abutments being mounted on a resilient portion of the stationary portion and/or of the movable portion, the resilient portion being deformable between an abutment configuration and a retraction configuration and having a reinforcement for reinforcing the resilient portion, namely a part that bears against a zone of the resilient portion.

Abstract: The device includes a membrane slidably mounted in a metering chamber, the membrane including a first sealing element forming a check valve, and a second sealing element enabling the membrane to slide in a leaktight manner relative to the metering chamber. The first and second sealing elements are made of a material that is relatively flexible, the membrane also including a rigid portion made of a material that is more rigid than the material of the first and second sealing elements.

Abstract: A liquid dispensing device including a sealing component which can take up a liquid release position and a liquid blocking position. The sealing component includes an elastomer part and a rigid part, these parts being fastened to each other when moving.

Abstract: A liquid dispensing device including a sealing component which can take up a liquid release position and a liquid blocking position. The liquid dispensing device also includes a surface for immobilising the sealing component in its blocking position, configured to prevent the sealing component from taking up its liquid release position.

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.

Abstract: A device for the back-injection of an implant including a user to hold the device, an injection needle, means for retaining the implant before the injection needle, means required for injecting the implant during withdrawal of the needle, protective means, capable of adopting an injection position leaving the needle uncovered and a safety position covering the needle again after use of the device, and return means designed to move the protective means into their safety position, the movement of the return means being controllable by the user.
