  • Patent number: 10335521
    Abstract: Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.

  • Patent number: 8936574
    Abstract: A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug delivery pump.

  • Patent number: 8936578
    Abstract: A medical injector is provided herein having a body with a displaceable plunger. The plunger includes a plurality of spaced-apart ratchet teeth disposed along the length thereof. At least one indexer is provided formed to engage the plunger, wherein the indexer is configured to allow the plunger to displace distally towards a distal end of the body but not proximally towards a proximal end of the body. The medical injector also includes an actuator having an engagement portion formed to engage one or more of the ratchet teeth. The actuator is displaceable to a ready state, the engagement portion being displaced proximally relative to the plunger with the actuator being displaced to the ready state. The indexer prevents proximal movement of the plunger thereby allowing the engagement portion to by-pass one or more of the ratchet teeth with the actuator being displaced to the ready state. In addition, the actuator is displaceable from the ready state to cause actuation of the medical injector.

  • Patent number: 8888750
    Abstract: A pen-type injector is improved so that a user may select a delivery dose of a medicinal product from a multidose cartridge. The injector includes a housing, the cartridge containing the medicinal product retained within the housing, a piston rod, a dose selecting member to select the dose of the medicinal product to be expelled, and a drive member to expel the selected dose of the medicinal product. The housing is formed unitary so that the dose selecting member and the drive member are moveably retained within the housing. The injector may include a ratchet associated with an insert to ensure the piston rod only rotates in a single direction through the insert, a button located on the drive sleeve, and a clutch which upon depression of the button prevents rotation between the dose dial sleeve and the drive sleeve.

  • Patent number: 8870831
    Abstract: A dose reset mechanism for a medicament delivery device with a housing and a medicament container includes a dose setting member in the housing for setting a dose when it is rotated and for resetting the dose when it is rotated in the opposite direction. The dose setting member has a drive member connected to a plunger rod such that when the drive member rotates, the rod moves axially; and a connection member between the dose setting member and the drive member. A ratchet mechanism enables the connection member to rotate when the dose setting member rotates for setting a dose but not to move in the opposite direction. At least one dose reset member and at least one blocking member are connected to the ratchet mechanism such that the connection member and drive member are released when a dose knob is turned in the opposite direction.

  • Patent number: 8858512
    Abstract: The present invention related to an injector is provided. The injector includes a case body, a dose setting, a first engagement, a second engagement, an elasticity element, and a button. The dose setting is used to preset a dose. The first engagement is connected with the dose setting. The elasticity element is connected between the first engagement and the second engagement. When the elasticity element is in an extension state, the first engagement and the second engagement are separated. When the button is pushed, the elasticity element is entered into a compress state to combine the first engagement and the second engagement, and then push the dose setting.

  • Patent number: 8721600
    Abstract: A delivery gun for discharging bone cement from a cartridge that includes a piston. The gun has a casing from which a drive rod and a disk extend. A drive assembly advances the drive rod and disk so that disk displaces the piston causing the discharge of cement. The drive assembly includes plural links that are pivotally connected to a trigger. The links are displaced in response to the manual displacement of a trigger. One of the links is configured to selectively engage the drive rod. When this particular link is engaged with the drive rod and displaced, the drive rod the drive rod is advanced at a first speed. When this link does not is not engaged with the drive rod, the drive rod is advanced by another link at a second speed.

  • Patent number: 8708971
    Abstract: A portable medicament dispensing device having a mechanism which is not susceptible to jamming for dispensing the medication to a user. The device employs a coupling for coupling the relative motion between reciprocating body members housing the ancillary components and a barrel plunger associated with the syringe. One embodiment provides a pivoting coupling whereas an alternate uses a rack and pinion system. The advantage of simplifying such mechanisms results in a structure which has smooth unencumbered motion with fewer parts to avoid mechanical jamming during use.

  • Patent number: 8672893
    Abstract: A syringe includes a barrel and a rotatable element on the barrel; for example at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle is held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. The barrel and plunger may be configured to cause the barrel to rotate as the plunger moves along the length of the barrel. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.
