Means For Preventing Accidental Displacement Of Piston Patents (Class 604/220)
  • Patent number: 10561795
    Abstract: A convertible plunger is provided comprising an internal portion and a generally cylindrical exterior surface. At least a portion of the exterior surface is maintained in an initial expanded state by a property of the internal portion. The expanded state is reducible to a constricted state by an operation that is applied to the internal portion of the plunger to alter the property. A film coating may also be applied to a sidewall of the sleeve to reduce a sliding friction between the sleeve and barrel. A film coating may also be applied to a nose cone of the plunger to provide a barrier between the plunger and product in the barrel.

  • Patent number: 10493210
    Abstract: In the present invention, a dripless syringe is provided that includes a barrel having fluid therein, the barrel defining an open end and a nozzle opposite the open end, a plunger disposed at least partially within the open end and including a body and a push pin extending from one end of the body, a seal plate slidably mounted to the push pin and a bung disposed over the seal plate and the push pin and sealingly engaged between the seal plate and the barrel the seal plate enables the bung to remain in sealing engagement with the interior of the barrel while the plunger is moved within the barrel. Further, when pressure is removed to cease dispensing of the fluid, the pin allows the bung to retract and provide a negative pressure on the fluid to prevent drips of fluid from leaking out of the nozzle.

  • Patent number: 10413673
    Abstract: The invention relates to a driving device for an injection device for administration of a liquid drug. The driving device has inter alia a rotary member, rotation of which relative to the housing causes a pretensioned spring to move a propulsion member in the dispensing direction, and a coupling which is closed and is opened by pressing of an actuating member, the opened coupling enabling the rotation of the rotary member in a first direction of rotation, and the actuating member being coupled to the rotary member such that pressing of the actuating member causes the rotary member to rotate already when the coupling is still closed.

    Abstract: A limiter for a dispensing device is provided. The limiter includes a body (20) arranged to mount with at least a portion of a dispensing device (300), and a stop extending from the body. The stop (40) is configured to permit movement a plunger of the dispensing device a predetermined distance in a dispensing direction correlated to a desired volume of medium to be delivered from the dispensing device. The stop is configured to prevent further movement of the plunger in the dispensing direction, thereby limiting the amount of medium delivered from the dispensing device. The dispensing device may be a syringe.

  • Patent number: 9522257
    Abstract: A controlled pressure inflation-deflation device inflates a balloon to occlude a blood vessel by moving a large plunger to provide incremental pressure increases within a syringe. A releasable latch moves a second plunger, positioned within a syringe formed by an inner columnar opening in the large plunger, between an occlusion position and a perfusion position. A three-position switch has a release position to allow the large plunger to move freely, an adjust position to provide the incremental pressure increases, and a lock position to lock the location of the plunger. Pressures at which various balloons (e.g., folded balloons) achieve or nearly achieve a substantially circular cross-section may be extrapolated by inflating balloons with pressures equal and/or greater than the first occlusion pressure. Balloons may be pre-inflated up to or below the first occlusion pressure to achieve a substantially circular cross-section, prior to increasing the balloon to an occlusion pressure.

  • Patent number: 8821440
    Abstract: An injection device has a dispensing chamber housing, a plunger, and a temperature control device. The dispensing chamber housing has a first part and a second part. The first part is thermally coupled to a needle. The second part is thermally coupled to the first part. The second part has an inner surface and an outer surface. The inner surface partially defines a dispensing chamber for holding a quantity of a substance. The plunger is engaged with an inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The temperature control device at least partially surrounds the dispensing chamber housing and is capable of altering a temperature of the substance in the dispensing chamber. The second part has a greater thermal coefficient than the first part.

    Abstract: A medicine injection device comprises a cartridge having a cartridge barrel and a plunger having a plunger shaft slidable within the cartridge barrel. The cartridge may have, e.g., a pre-filled medicine. The medicine injection device further comprises a body having a proximal end, a distal end, and a cavity in which the cartridge barrel is disposed. The proximal end of the body may optionally form a finger grip. The medicine injection device further comprises a plunger locking mechanism attached to the proximal end of the body. The plunger locking mechanism comprises a member with an aperture slidably engaged with the plunger shaft. The locking mechanism is configured for preventing the plunger from being removed from the cartridge barrel. For example, the plunger shaft may include a locking stop, e.g., a flange, that engages with the aperture in an interference arrangement.
