摘要:
External electromagnetic stimulation of the interior of the body by applying three or more electrodes to the exterior of the patient to establish at least two electrical paths across the interior of the patient, determining impedance information representative of an impedance distribution across the interior of the body, delivering an electromagnetic waveform across each of the at least two electrical paths, wherein at least one parameter of the waveform is selected using the impedance information to produce a selected current density distribution at one or more locations within the interior of the body.

The present invention is directed to a luminometer and methods which provides simple and effective measurement of a plurality of wells in a plurality of strips in an automatic fashion. The luminometer may be used in CLIA (Chemi Luminescent Immuno Assays). The luminometer allows for CLIA micro strip reading, and reads break-apart wells, with a plurality of wells per strip, and calculates results instantly and automatically. The luminometer has an automatic carrier positioning system which selectively positions the plurality of wells in the plurality of strips at a measuring position, wherein the drive system associated with the positioning system drives the carrier along a single axis of movement. An optical track system automatically provides Y axis movement of the carrier. The luminometer may have a calibration system for maintaining proper operation of the system in measurements therewith.
摘要:
A medical device of the type used for assisting a user in manually delivering repetitive therapy to a patient (e.g., chest compressions or ventilations in cardiac resuscitation), the device comprising a feedback device configured to generate feedback cues to assist the user in timing the delivery of the repetitive therapy, at least one sensor or circuit element configured to detect actual delivery times, at which the user actually delivers the repetitive therapy, and a processor, memory, and associated circuitry configured to compare the actual delivery times to information representative of desired delivery times to determine cue times at which the feedback cues are generated by the feedback device.
摘要:
A method of emulsifying a substituted cyclic dicarboxylic acid anhydride sizing agent such as alkenyl succinic anhydride (ASA), primarily for papermaking operations, uses a cationic reaction polymer synthesized from an epihalohydrin and a polyamine, preferably a polyalkyleneamine. The synthesis of the reaction product is controlled to obtain a polymer end product viscosity, by Brookfield, ranging between 50 and 300 cps at 25° C. and at 30 to 35% solids. Alternatively, the preferred cationic polymers can be described as having an intrinsic viscosity value in a 0.2M NaCl solution of 0.18 to 0.35 dL/gm at 30° C. The polyamine-epihalohydrin polymers can also be optionally used in combination with a surfactant for further emulsifying of the ASA size.
摘要:
A method of treating a patient in cardiac arrest (e.g., in fibrillation, electrochemical dissociation, or asystole), the method comprising delivering an agent for enhancement of cardiac function to the coronary arteries of the patient; and microperfusing the patient's cardiac tissue by electromagnetically stimulating the cardiac tissue at an energy level below a threshold sufficient to defibrillate the heart.
摘要:
A printer includes a print head for dispensing viscous material, such as solder paste. The print head defines a chamber and includes at least one source port and a dispensing slot. Within the chamber, a flexible membrane segregates the chamber into a dispensing region and an activation region. Viscous material flows from a supply mounted to the source port, into the dispensing region and out the slot. A displacement mechanism is positioned to displace the flexible membrane to reduce the volume of dispensing region and to thereby dispense viscous material through the slot. The print head also includes a removable envelope through which the viscous material flows and contacts as it passes through the envelope.

摘要:
A method for improving the cardiac output of a patient who is suffering from pulseless electrical activity or shock and yet still displays some myocardial wall motion including sensing myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase. In such cases, a compressive force is repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion. Also incorporated may be a logic circuit capable of utilizing multiple sensing modalities and optimizing the synchronization pattern between multiple phasic therapeutic modalities and myocardial residual mechanical function.
