A disposable active pulse sensor has an emitter that generates optical radiation having a plurality of wavelengths, a detector that is responsive to the optical radiation and an unbalanced electrical motor that vibrates when energized. A tape assembly removably attaches the emitter, the detector and the unbalanced electrical motor to a tissue site. The tape assembly also physically mounts the emitter, the detector and the unbalanced electrical motor in a spatial arrangement so that vibration from the unbalanced electrical motor induces pulsatile blood flow within the tissue site, the emitter transmits the optical radiation into the tissue site and the detector generates a sensor signal responsive to the intensity of the optical radiation after attenuation by the pulsatile blood flow within the tissue site.

The invention provides exemplary methods and apparatus for dispensing liquids as an atomized spray. In one particularly preferably method, a liquid is dispensed as an atomized spray from a vibratable member having a front surface and a rear surface, with the member having at least one tapered hole between the surfaces for dispensing the liquid. The tapered hole has a larger cross-sectional area at the rear surface than at the front surface. The liquid is delivered from a supply container to the rear surface of the vibratable member in an amount sufficient to cover the hole with liquid. The vibratable member is then vibrated to dispense at least a portion of the liquid through the hole and from the front surface. Additional liquid is delivered from the supply container and to the rear surface in volumes that are substantially equal to the volumes dispensed.

A system for collecting, managing and disseminating information relating to medical procedures includes a central computer and a plurality of medical devices each in communication with an injector, a scanner, a hospital system and / or at least one other device. Each medical device receives (I) before a procedure is performed, patient identification information from a user interface, the scanner and / or the hospital system and (II) during and / or after the procedure, injection information from the injector and imaging study information from the scanner. Each medical device has an associated database for storing as a record therein the patient identification information, the injection information and the imaging study information for each procedure performed on each patient. The central computer remotely links to each medical device for accessing, collecting and storing in a related database the records transmitted therefrom and for analyzing the records and creating therefrom at least one related entry based thereon.

An exercise device having a water-tight, interior compartment into which a destabilizing liquid can be added to fill the device to a desired weight, such as by indicated on weight marks provided on an exterior surface of the exercise device. The device is capable of being filled with the destabilizing liquid via a water port of the device, which may be releasably securable to a water hose or faucet. The destabilizing liquid filling the interior compartment of the exercise device provides resistance to muscular movement and provides destabilization of the device as an aid in improving a user's balance and coordination. Handles and / or at least one protruding knob are provided on the exterior surface of the exercise device, and / or padded straps are provided on the exterior surface of the exercise device for attaching the device to the user's limbs or back. One side of the device may be flattened and padded to increase comfort for the user when the device is attached to the user's body.
