  • Patent number: 10730128
    Abstract: A solder ball bonding (SBB) tool includes a rotatable feed plate for transporting solder balls from a translatable solder ball reservoir to a nozzle unit, which is a position at which a laser light source can irradiate and thus melt the solder balls. The SBB tool includes a gap between the reservoir and the feed plate positioned over the reservoir, and a feed mechanism coupled with the reservoir, where the feed mechanism is driven by a pressurized gas to translate the reservoir upward across at least a portion of the gap in preparation for movement of a solder ball to the feed plate and downward in preparation for rotation of the feed plate after a solder ball is moved to the feed plate. The gap may have a maximum size that exceeds a nominal size of the solder balls contained in the reservoir.

  • Patent number: 10537335
    Abstract: In some examples, a medical dispensing device includes a housing and a trigger. A first engager of the device is configured to move axially as the trigger pivots. As the first engager moves, it engages a rod. A maximum proximal position of the rod is defined by a stop. A spring presses the first engager into the trigger such that either the trigger or the first engager rests against a stop limiting rotation of the trigger. A second engager moves axially as the trigger pivots. At the actuated position the second engager, defined by a stop, the second engager limits proximal movement of the rod. An assembly transfers movement of the trigger to the second engager after the trigger has pivoted a threshold amount. A member of the assembly distally moves the second engager. Until it is at the actuated position, the second engager enables the rod to proximally move.

  • Patent number: 10166337
    Abstract: A hand-activated syringe (14) is disclosed that uses a vacuum to retract a plunger (54) of the syringe (14) to draw fluid into a syringe body (18). A first seal (76) with the plunger (54) and a second seal (64) with the plunger (54) define a vacuum chamber (82). The spacing between the first seal (76) and the second seal (64) changes in response to the plunger (54) moving relative to the syringe body (18). Advancing the plunger (54) in a direction associated with a discharge stroke creates or increases a vacuum within the vacuum chamber (82) by increasing a spacing between the first seal (76) and the second seal (64). This vacuum thereafter may be used to retract the plunger (54) by decreasing a spacing between the first seal (76) and the second seal (64), and to thereby draw fluid into the syringe (14) from a fluid source (86).

  • Patent number: 9731953
    Abstract: A cylinder-and-piston assembly for a bottle attachment apparatus for handling liquids in which the stroke length of the piston of the cylinder-and-piston assembly is delimited by a stroke length stop when suctioning from the cylinder and is delimited by a readjustment stop when exhausting into the cylinder. The readjustment stop is disposed on the piston or on the cylinder housing and interacts with a fixed stop. The readjustment stop is accessible and adjustable by way of a removable seal. The seal is connected by way of ribs to a piston bearing. The readjustment stop is disposed below this removable seal. The seal has a molding and the piston bearing has a counter molding. Displacement of the seal in relation to the piston bearing moves the seal in the longitudinal direction, and by this movement, the seal is removed in a manner that preferably is not capable of re-assembly.

  • Patent number: 9604009
    Abstract: A drive mechanism suitable for use in drug delivery devices is disclosed. The drive mechanism may be used with injector-type drug delivery devices, such as those permitting a user to set the delivery dose. The drive mechanism may include a housing, a dose dial sleeve, and a drive sleeve. A clutch is configured to permit rotation of the drive sleeve and the dose dial sleeve with respect to the housing when the dose dial sleeve and drive sleeve are coupled through the clutch. Conversely, when the dose dial sleeve and drive sleeve are in a de-coupled state, rotation of the dose dial sleeve with respect to the housing is permitted and rotation of the drive sleeve with respect to the housing is prevented. In the de-coupled state, axial movement of the drive sleeve transfers force in a longitudinal direction for actuation of a drug delivery device.

  • Patent number: 9555192
    Abstract: The instant application is directed to an assembly for a drug delivery device which is arranged to operate in two distinct modes, a priming mode starting from a pre-priming state and a dispense mode operating in a post-priming state, and a drug delivery device comprising this assembly. The assembly comprises a dose member, an actuating member and a piston rod which is configured to act on a bung of an assembled cartridge containing the drug. In the pre-priming state the actuating member is configured to be moved by a user such that the movement of the actuating member causes a movement of the dose member and such that the movement of the dose member causes a movement of the piston rod. In the post-priming state the dose member is configured to be moved by a user without causing a movement of the actuating member in order to perform a set and dispense action of the drug delivery device.
