摘要:
A syringe assembly including a syringe and a safety device, the syringe including a barrel of tubular shape, the safety device including a member of tubular shape referred to as a syringe support in which the barrel is arranged such that the syringe support and the barrel are secured on the same axis. The syringe barrel has a flange at a proximal end that is prevented from moving in translation between a peripheral bearing seat and an abutment of the support. Interposed between the seat and the flange, the assembly includes at least one compression pad between the seat and the flange and made of a material presenting a coefficient of friction relative to at least one of the materials of the flange and of the seat that is greater than the coefficient of friction of the materials of the flange and of the seat relative to each other.

The safety device for an injection syringe includes a syringe support, a protective sheath for protecting an injection needle carried by the syringe, the sheath being mounted to slide relative to the syringe support between an injection position in which the needle is uncovered, and a protection position in which the needle is covered, the sheath having a grip surface enabling the device to be gripped by a user and referred to as the initial grip surface, and a return spring for urging the sheath into the protection position. The sheath also includes an extender member for extending the initial grip surface and fitted on the sheath in such a manner as to present a larger grip surface, referred to as an enlarged grip surface.
摘要:
The syringe comprises a body containing the liquid and having fitted thereto an endpiece for fastening a needle carrier. The safety device comprises a protective sheath and a syringe support that is received inside the sheath. The sheath and the support are axially movable relative to each other between two positions, namely an uncovered position of the needle, and a retracted position of said needle. The support includes anti-rotation means for constraining it in rotation about its axis and comprising at least one pawl urged resiliently into a position in which the pawl is designed to co-operate with complementary anti-rotation means of the fastener endpiece. The sheath and the support include complementary anti-rotation means for constraining them in rotation relative to each other about their axes and activated at least when the sheath and the support are in their uncovered position of the needle.

The syringe comprises a body containing the liquid and having fitted thereto an endpiece for fastening a needle carrier. The safety device comprises a protective sheath and a syringe support that is received inside the sheath. The sheath and the support are axially movable relative to each other between two positions, namely a disengaged position of the needle, and a retracted position of said needle. The support includes anti-rotation means for constraining it in rotation about its axis and comprising at least one pawl urged resiliently into a position in which the pawl is designed to co-operate with complementary anti-rotation means of the fastener endpiece. The sheath and the support include complementary anti-rotation means for constraining them in rotation relative to each other about their axes and activated at least when the sheath and the support are in their disengaged position of the needle.

摘要:
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.
摘要:
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.
摘要:
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.
