Abstract

This disclosure describes a portable, separable unit containing heart monitor and defibrillator portions. Both units have separate, rechargeable power supplies. This enables separate operation of the monitor portion when it is removed from the combined unit housing. Switch means within the monitor portion are automatically operated when the latter is placed in the main console thereby interrupting flow of power between the monitor power supply and the various monitor circuits. Additional switch means within the defibrillator portion can then be operated to bypass the interruptive effect of the automatic switch means and enable the monitor circuits to again be powered by its respective power supply.

Claims

1. A portable unit including heart monitor and heart defibrillator portions which comprises:

a. a removable heart-monitoring portion having a self-contained power supply, said monitoring portion capable of monitoring a patient'"'"''"'"'s heart, while positiOned in said unit or removed therefrom;

b. first switch means for interrupting the flow of electric power between said power supply and electrical circuits within said monitor portion when said monitoring portion is positioned in said unit;

c. second switch means within said defibrillator; and

d. means for electrically connecting said power supply and said electrical circuits within said monitoring portion to said second switch means, said second switch means operable to connect said power supply to said electrical circuits.

2. The unit of claim 1 where said first switch means is automatic and is operable when said monitoring portion is positioned in said unit.

3. The unit of claim 2 where said first switch means is a spring loaded, button type switch.

4. The unit of claim 1 where said second switch means includes a first and second ON position, where said first ON position allows only said monitor unit to have said electric power supplied thereto.

5. The unit of claim 1 where said heart-defibrillator portion has its own self-contained power supply for energizing said defibrillator portion with or without said heart monitor portion removed.

6. The unit of claim 5 where both of said power supplies are batteries and rechargeable.

7. The unit of claim 1 where said power supply is a battery and is rechargeable.
