Abstract:
An apparatus includes a housing, a medicament container and an actuator. The actuator includes a release member and an energy storage member having a first position and a second position. In the first position, the energy storage member has a first potential energy. In the second position the energy storage member has a second potential energy. The energy storage member is configured to convert a portion of the first potential energy into kinetic energy when moved from the first position to the second position to move the medicament container within the housing. The energy storage member has a longitudinal axis offset from a longitudinal axis of the medicament container. The release member is configured to selectively deploy the energy storage member from its first position to its second position.

The movable member is configured to be disposed within a housing of a medical device and has a first end portion and second end portion. A portion of the first end portion is configured to define a portion of a boundary of a gas chamber. The first end portion defines an opening configured to be in fluid communication between the gas chamber and an area outside the gas chamber. The second end portion is configured to be coupled to a needle configured to deliver a medicament into a body. The valve is configured to selectively allow fluid communication between the gas chamber and the area outside the gas chamber through the opening defined by the first end portion of the movable member.

Abstract:
Apparatuses for automatic medicament injection and methods for manufacturing automatic medicament injectors are described herein. In some embodiments, an apparatus includes a housing, a needle, an energy storage member, an actuator, a locking member, and a needle guard. The needle is configured to move between a first position and a second position. In its first position, the needle is contained within the housing. In its second position, at least a portion of the needle extends from the housing. The energy storage member has a first configuration and a second configuration and is configured to produce a force when moving between its first configuration and its second configuration to move the needle from its first position to its second position. The actuator is configured to move the energy storage member from its first configuration to its second configuration. The locking member is movably coupled to the distal end portion of the housing such that the locking member can be moved between a first position and a second position. In its first position, the locking member is configured to engage the actuator to prevent the actuator from moving the energy storage member to the second configuration. The needle guard is removably coupled to at least one of the distal end portion of the housing or a base movably coupled to the distal end portion of the housing.
Abstract:
An apparatus includes a container defining an internal region configured to contain multiple medicament delivery devices, such as, for example, pen injectors, auto-injectors, inhalers or the like. The container includes an electronic circuit system configured to output a first electronic output associated with a first medicament delivery device contained within the internal region when the first medicament delivery device is removed from the internal region of the container. The electronic circuit system is further configured to output a second electronic output associated with a second medicament delivery device contained within the internal region when the second medicament delivery device is removed from the internal region of the container. The second electronic output is different than the first electronic output. At least one of the first electronic output or the second electronic output is associated with a use instruction.
Abstract:
The present invention is directed to a method and apparatus for preventing damage to drapes and to heating and cooling mechanisms used in conjunction with apparatus for containing and thermally treating sterile liquid, and to preserving the sterile field when using such apparatus. A surgical drape is combined with a sensor, preferably attached to the drape, to detect whether or not liquid is present in a drape container conforming to a heating/cooling basin. An alternative embodiment employs sensors at opposite surfaces of the drape to measure conductance and, thereby, leakage through the drape. A microprocessor in each embodiment receives a signal representing, for example, an electrical conductance measurement from the sensors and determines if liquid is present, or alternatively if the conductance is sufficient to represent the presence of a leak. If liquid is not present or a leak is determined to exist, the microprocessor disables a temperature controller for the basin to prevent damage to the drape and heating and cooling mechanisms.
Abstract:
Frozen pieces o sterile medium, such as saline, are dislodged from a sterile drape container in a surgical slush producing machine by manipulating the drape relative to the cooled basin to which the drape container conforms. Manipulation of the drape is achieved by pushing, twisting, pulling, lifting, etc. on the drape to displace it from the basin. Such movement of the drape may be effected on a continuous and automatic basis, or by manual means using a member or implement to facilitate drape movement. The system cabinet includes a refrigerated compartment for pre-chilling sterile liquid to be used in forming the surgical slush.
Abstract:
Blood clot analysis instrumentation used to evaluate platelet function and clot structure by monitoring force development during clot retraction or upon application of a known amount of force can have a calibration check automatically performed by using a top member with a known amount of mass which is detachable from the instrumentation, and preferably is a disposable component. The calibration check is performed by monitoring force or displacement on a holding member with and without the top member attached. If the difference measured is within a preferred tolerance range, then the instrumentation can be deemed to be within the specifications deemed best suited for the instrument. The top member may also be modified to allow for mixing reagents with the clot, thereby avoiding the need to pre-mix blood with reagents before measurement. This can be accomplished by providing the top member with a rotation mechanism, such as an air driven fin assembly, that permits the top member to rotate forwards and/or backwards relative to the receptacle which holds the blood sample. The top member may also carry on board one or more reagents used for the diagnostic tests to be performed on the blood sample. Different top members might be used to perform different tests by being capable of dispensing different reagents. Moreover, a bar code or other indicia may be used to have the instrumentation automatically identify the test being performed, and this can also be used to provide information useful in regulating the mixing operation to be performed by the top member. Furthermore, a disposable liner may also be positionable within the receptacle such that the entire test can be performed with disposable components, thereby reducing clean up time, improving performance of the instrumentation, and enhancing the safety for the clinicians. Finally, the shape of the top and bottom members are configured in such a way as to have the evaporation force vector perpendicular to the clot retraction force vector.
Abstract:
A sterile drape assembly includes a sheet of sterile drape material bonded to a disk-like member. The drape establishes a sterile field atop a surgical slush machine and is conformable to a cooling basin to provide a drape container impervious to the sterile slush medium. The disk-like member is preferably bonded to the bottom of the drape container and is engageable by a movable member projecting into the basin. The movable member (e.g., a longitudinally reciprocable vertical shaft) moves the member and the drape to dislodge frozen pieces of the sterile medium that attach to the sides of the drape container.
