Abstract: The present disclosure relates to an injection device, in particular a micro dose injection device such as, for example, an ophthalmic injection device. An example device comprises a rotatable plunger; a solution receptacle having a first end configured to slidably receive the rotatable plunger and a second end configured to dispense solution contained in the solution receptacle; a first stop member configured to prevent the rotatable plunger from being slidably displaced to a second position while the rotatable plunger is at a first position and in a first orientation; and a second stop member configured to prevent the rotatable plunger from rotating in a first direction about the first axis while the rotatable plunger is at the first position and in the first orientation, wherein slidably displacing the rotatable plunger from the first position to the second position dispenses a quantity of the solution contained in the solution receptacle.

Abstract: Embodiments of negative pressure wound therapy systems, apparatuses, and methods for operating the systems and apparatuses are disclosed. In some embodiments, the apparatus includes a negative pressure source, a connector port, at least one switch, and a controller. The negative pressure source is connected through the connector port to either (i) a wound dressing having a canister configured to store fluid aspirated from the wound or (ii) a wound dressing without a canister between the connector port and the wound dressing. The controller determines, based on a signal received from the at least one switch, whether the canister is positioned in the fluid flow path and adjusts one or more operational parameters of negative pressure wound therapy based on the determination. The switch is activated by the connection of either the canister or canisterless wound dressing to the apparatus.

Abstract: A toy vehicle play set may include a toy vehicle and a track assembly including a track along which the vehicle may travel. In some examples the vehicle may include a drive mechanism that is adjustable for changing the speed of the vehicle, and a play set may include a speed changer for selectively changing the vehicle speed. In some examples, the track assembly may include a selectively actuated trapdoor in the track. In some examples, the play set may include a vehicle trap assembly having a cover defining a chamber for receiving, for example, a vehicle passing through the trapdoor opening. In some examples, the vehicle trap may include an assembly, such as the vehicle trap that falls apart when contacted by a vehicle traveling along the track.

Abstract: A medical safety device is provided and includes a needle hub having a needle supported thereon; and a safety shield operatively mounted on the needle hub. The safety shield includes a pair of spaced legs and a foot member. Each proximal segment includes a camming surface. The safety shield further includes a trigger supported on the foot member. The trigger includes a camming member and is movable to move the camming member into engagement with the camming surfaces of the proximal segments to effect movement of the legs from a first position in which the distal ends of the distal segments shield a distal end of the needle to a second position in which the distal end of the needle is at least partially exposed. The trigger is removably secured to the foot member.

Abstract: The present disclosure is directed to a toy play set for use with a toy vehicle comprising a platform attached to a support structure. In some examples, the play set may include a base and a support structure pivotally attached to the base with the support structure adapted to pivot relative to the base. In other examples, the toy play set may include a platform pivotally attached to the support structure and adapted to rotate in a toy vehicle's direction of travel. In still other examples, the toy play set may include first and second elongate tracks and means for carrying a toy vehicle from the first elongate track to the second elongate track. One disclosed embodiment includes first and second elongate tracks, a base, a support structure pivotally attached to the base, a platform pivotally attached to the support structure wherein the platform and support structure pivot at perpendicular axes that are parallel to the ground, and a vehicle receiving apparatus attached to the second elongate track.

Abstract: In some examples, a toy vehicle play set may include an elongate track having a first vehicle-support surface defining a travel path, and a carriage mounted for travel along the travel path and having a second vehicle-support surface. The first and second vehicle-support surfaces may be configured to support, in combination, a toy vehicle.

Abstract: A safety device for a needle is provided. The device includes a spring biased sheath which acts to cover the needle before and after use. The safety device also includes a spring biased lock which is operable to lock the sheath in a safe position unless the biasing force of the lock is countered by a user.

Abstract: A safety device, usable in particular with hypodermic needles, and incorporating a trigger mechanism which when activated primes the device to initiate the unsheathing of the needle in use by flexing one or more needle-surrounding legs away from the needle axis; the initial priming and leg-flexing movement being caused by the interaction of an operative portion of the trigger with the or each said leg or with a member connected operatively thereto; characterised by the feature that, when such movement occurs, the trigger end interacts with the leg or the said, part connected thereto in a manner which positively latches and retains the two in engagement.
