DEVICE FOR APPLYING A FLUID
20220193345 · 2022-06-23 ·

A device for administering a fluid, wherein, with the valve opened, fluid that is to be administered can be brought through the feed channel into the cylinder, and wherein a movement of the piston counter to the first direction towards the open dispensing end generates a positive pressure in the cylinder, such that, with the first valve opened, the fluid that is to be administered from the cylinder is dispensed via the open dispensing end, wherein, in order to seal the rear end of the cylinder, a first sealing element is arranged between the piston and the cylinder and a second sealing element is arranged spaced apart from the first sealing element along the first direction. The first sealing element can be a single-acting sealing element, and the second sealing element can be a single-acting or double-acting sealing element.

Ophthalmic device

An ophthalmic device including a cannula having a cannula distal end, a lumen, and one or more orifices coupled to the lumen is provided. The cannula is configured to deliver a fluid. A sleeve is disposed around the cannula and has a sleeve distal end. A handle is coupled to the sleeve and the cannula, the handle having an actuator. An internal mechanism is coupled to the actuator and configured to retract the sleeve relative to the cannula. The internal mechanism includes a follower fixedly coupled to the sleeve and moveable between distal and proximal positions, and a release member movable between an activated position and a release position. The release member is coupled to the actuator and configured to release a force that urges the follower from the distal position to the proximal position when the release member moves from the activated position to the release position.
