US Patent:

54963494, Mar 5, 1996

Filed:

Mar 11, 1994

Appl. No.:

8/209774

Inventors:

Dean D. Campbell - Seattle WA
Robert A. Wiley - Tukwila WA

Assignee:

Physio-Control Corporation - Redmond WA

International Classification:

A61N 139

US Classification:

607 5

Abstract:

A method and system for automatic or semi-automatic defibrillation using redundant processing is provided. In a preferred embodiment, two microprocessors each separately analyze electrocardiogram signals from a patient in order to separately determine whether the patient should be treated. If both microprocessors determine that the patient should be treated, a treatment subsystem defibrillates the patient by delivering a defibrillation charge to the patient. In a semi-automatic embodiment, the treatment subsystem only delivers a defibrillation charge to the patient if a human operator has responded to a visual indication that the patient should be treated by manually activating the defibrillator.

Appl. No.:

8/188240

Inventors:

Abraham H. Kou - Redmond WA

Assignee:

Physio-Control Corporation - Redmond WA

International Classification:

H02J 700
H01M 1044

US Classification:

320 15

Abstract:

A battery selecting and charging system forms part of a portable electronic device, preferably a portable medical device. When the device is powered up, a selecting circuit selects one of two rechargeable batteries to power the device until it is depleted, and then automatically switches to the other battery. When the second battery is depleted, both batteries are selected to power the device. When the device is powered down, a battery charging circuit, having both a high and low charge section, provides a high charge to the battery having the greatest terminal voltage. Thereafter, the high charge is applied to the other battery, the low charge is applied to the first battery, and then the low charge is applied to the second battery. The battery charging circuit monitors the terminal voltage to prevent any damage to the batteries or the device.

International Classification:

G01R 1512
A61N 139

US Classification:

364481

Abstract:

A portable electronic unit, such as a defibrillator, includes an autotest system for automatically self-testing various electrical components within the unit during quiescent periods. The autotest system includes an autotest routine that performs an extensive array of rigorous yet time-consuming tests that are impractical to perform during normal modes of operation of the unit. A real-time clock can be set to initiate the autotest routine at a time when the unit is unlikely to be used for its normal mode of operation. The autotest system provides a strip chart printout of the results of the various self-tests performed on the unit, and provides messages on a visual display of any error conditions. If the autotest system detects a needs service malfunction, the operator must acknowledge the error with an input to the unit before the unit will enter into its normal mode of operation. If the autotest system detects a service mandatory malfunction, the unit will discontinue any normal mode of operation until the malfunction is corrected.
