Abstract: An infusion pump system including an infusion tubing for delivering a fluid, a heat exchanger cartridge in fluid communication with the infusion tubing and removably coupled to at least one thermal element for heating or cooling the fluid, a motor driven pump in mechanical communication with the infusion tubing and configured to pump the fluid through the infusion tubing and the heat exchanger cartridge, and a central controller in electrical communication with the motor driven pump and the at least one thermal element. The central controller is configured to selectively deliver the fluid to a patient without heating or cooling the fluid by causing the motor driven pump to pump the fluid through the infusion tubing and the heat exchanger cartridge while the thermal element is off.

Abstract: A pump system selectably and dynamically controls the flow rate of a fluid being delivered to a patient's body over a wide range of flow rates. The pump system includes an infusion tubing, a pumping mechanism, a motor drive assembly in mechanical communication with the pumping mechanism, a user input control, and an electronic controller in electrical communication with and at least partially controlling the motor drive assembly. The electronic controller include a digital signal processing controller in electrical communication with the motor drive assembly that is configured to receive a signal from the user input control and to cause power to be supplied to the motor drive assembly in response at least partially to the signal from the user input control. The pump system may selectably deliver fluid at rates from about 1 milliliter per hour to at least about 3000 milliliters per minute.

Abstract: An improved plunger comprises a generally V-shaped handle attached to a top distal end of a shaft. The handle comprises two mirrored arms that face inwards from a base so that neither of them nor the shaft shares a vertical or a horizontal plane. The handle is removably detachable from the plunger so that it can be washed, disinfected, and sanitized. At least one extension shaft portion extends a height of the shaft when it is not collapsed into and housed in the hollow shaft. A snaking attachments formed of a linearly aligned, spiral wound coil has an attachment end attachable to said dislodging protrusion.

Abstract: A pump system selectably controls the temperature, flow rate, flow volume, and flow pressure of a fluid being infused into a patient's body. The pump system includes a cartridge and components that removably connect with a pump housing and corresponding components, providing simple attachment of the cartridge to the pump housing. The pump housing includes a pressure sensor, a bubble detector, and a temperature sensor on a first side of the pump housing, and an engaging actuator and a central controller. The cartridge includes on a first side a heat exchanger, a pressure receptor correspondingly aligned with the pressure sensor, and a detector interface correspondingly aligned with the bubble detector and temperature sensor. Upon aligning the cartridge with the pump housing and actuating the engaging actuator, the pressure receptor communicates with the pressure sensor and the detector interface aligns with the bubble detector and temperature sensor.

Abstract: The article of the invention is a tray for a furniture unit of the type used as a workstation. The tray has a base with two supports attached to parallel sides of the base. The supports are in slidable, rotatable communication with a support member which may be moved between a substantially upright and a substantially co-planar position with respect to the base. In the substantially upright position, the support member may support copy such as documents or a book, for example. In the co-planer position, the support member may function as a writing surface or as a shelf for supporting small articles and the like.

Abstract: In order to investigate and analyse vibrations of any object, light from a laser is split with part being emitted to an object and part being mixed with the light reflected from the object to create an interference signal. That interference signal is investigated to derive therefrom a signal representing the vibrations of the object If there is bulk movement of the object, the effect of that bulk movement may impose a popular shift on the reflected light. To eliminate this from the investigation of the vibrations of the object, an estimate of frequency corresponding to the effect of the bulk movement is derived from the signal, and that used to defuse a signal of reduced bandwidth encouraging the frequency due to the bulk movement and also the frequencies of vibration Thus, the vibrations can then be derived and investigated from analysis of that signal of reduced bandwidth.

Abstract: An apparatus for marking a target. The apparatus includes a soft rupturable capsule and a marking agent contained in the capsule. The capsule is rupturable on impact with the target to release the marking agent from the capsule. The marking agent has a visual staining component and an odorous staining component.
