Abstract: An automated external defibrillator (210) for use during CPR comprising: a first electrode pad (370a) configured to obtain an electrocardiogram (ECG) signal from an individual; a second electrode pad (370b) configured to obtain ECG signal from the individual, wherein the first and/or the second electrode pad comprises an electrode pad visual display (372) configured to be visible while providing CPR to the individual; a controller (310) configured to: (i) process an electrical and/or an accelerometer signal to determine a depth of one or more chest compressions during CPR; (ii) compare the determined depth of the chest compressions to a threshold depth; (ii) determine, based on the comparison, that the determined depth exceeds or falls below the threshold depth; and (iii) direct the electrode pad visual display to provide a depth indication to the user that the determined depth of the chest compressions exceeds or falls below the threshold depth.

Abstract: A digital interface has a main screen having a treatment screen and a scroll bar. The treatment screen includes a list of treatment inputs. The scroll bar has a displacement detection area, and the scroll bar scrolls to a divider in the list of treatment inputs in response to movement along the displacement detection area. The treatment screen displays the list of treatment inputs beginning with the divider.

Abstract: A body scrubbing brush apparatus comprises a base support, a brush panel having a front brushing surface, and means for non-rotatably moving the brush panel in a small orbital path relative to the base support. Such movement may be achieved with an hydraulic drive mechanism, and the entire apparatus may be mounted to the wall of a shower bath.

Abstract: Authentication and verification of suitability for use of disposable elements can be made by evaluation of characteristic data stored on a non-volatile read/write memory element, especially useful in a photoactivatable agent patient treatment system wherein photoactivatable agents, in contact with patient blood cells, are irradiated extracorporeally and then returned to the patient.

Abstract: A removable U.V. light array assembly for use in a photoactivatable agent, patient treatment system wherein photoactivatable agents, in contact with patient blood cells, are irradiated extracorporeally and then returned to the patient.

Abstract: Pump block for interfacing an irradiation chamber with a roller pump in an apparatus for use in a photoactivatable agent, patient treatment system wherein photoactivatable agents, in contact with patient blood cells, are irradiated extracorporeally and then returned to the patient.

Abstract: A monitor and control system for water purification apparatus includes first and second conductivity cells located in the input water path and the purified product water path of the apparatus, respectively. The conductivity cells produce output signals exhibiting amplitudes representative of the impurity concentrations in the respective water paths. These signals are detected and modified by circuitry which imposes logarithmic characteristics upon the two signals. The two logarithmically variable signals are differentially combined to produce a signal for display which is representative of the percent of impurity rejection of the water purification apparatus. The detected signal are also individually combined with signals representative of the temperature of the water being processed. The temperature-corrected signals are then displayed to provide an indication of the impurity concentrations of the input and purified water paths in parts per million.

Abstract: Provided are apparatus and methods of use for extracorporeally treating a patient whereby blood is withdrawn from the patient, separated into a leukocyte enriched portion which, in contact with a photoactivatable reagent, is irradiated and all blood portions being returned to the patient. The preferred apparatus is suitably modified with appropriate tubing sets, valves, pumps, centrifuge and controlling means to perform the patient treatment in three operational phases.

Abstract: Methods are provided for ensuring the safety of a patient undergoing extracorporeal treatment by irradiation of a photoactivatable reagent in contact with the patient's blood including simultaneous digital and analog monitoring of temperature, voltage and current sensor signals. Also provided is a control system for controlling and regulating the various components of the photophoresis patient treatment system.

Abstract: Automated control methods and apparatus are provided for the separation and collection of desired blood portions for use in an extracorporeal photophoresis treatment system wherein a photoactivatable agent, in contact with leukocyte enriched blood from a patient is irradiated and then returned to said patient.
