Abstract

An installation for sequentially monitoring a plurality of objects or persons such as heart patients includes connections to a heartbeat signal generator on each patient, a stepping and switching circuit acting to connect each such connection in sequence to a signal evaluator or monitor for a period sufficient for the monitor to measure the rate and for intensity of each input signal, means enabling the monitor to stop the switching circuit on any connection affording a signal which indicates an unusual or dangerous heart condition, and means for giving an alarm under such a condition.

Claims

1. An installation for combined monitoring and influencing of a plurality of objects, comprising a plurality of input channels individually associated each with an object, common measuring and indicating means for said plurality of input channels, automatic switching means for successively connecting each of said input channels to said common measuring and indicating means, means for detecting an alarm condition in anyone of said plurality of input channels and for stopping said switching means upon detection of an alarm condition, a like plurality of output channels individually associated each with a corresponding one of said objects, common treating means for overcoming said alarm condition of said objects, said switching means including contacts for successively interconnecting one of said output channels with said treating means in synchronism with the successive connection of corresponding input channels to said measuring and indicating means such that each pair of input and output channels associated with one object is repeatedly connected simultaneously to said measuring and indicating means and to said treating means.

2. An installation as recited in claim 1, including means for adjusting the period during which each input channel and corresponding output channel is operative.

3. An installation as recited in claim 1, wherein said switching means include an impulse generator the impulses of which progressively step said contacts.

4. An installation as recited in claim 3, wherein said switching means include a program selector defining a required switching sequence.

5. An installation as recited in claim 4, including a manual selector capable of overriding said program selector and closing said contacts in a predetermined input and output channel.

6. An installation as recited in claim 3, including a suppressing gate between said impulse generator and said contacts, said gate having a control input from said means for detecting an alarm condition, said gate being controlled to suppress the transmission of impulses to said contacts upon occurrence of an alarm condition.

7. An installation as recited in claim 1, including an alarm indicator connected to said means for detecting an alarm condition, said alarm indicator being actuated when an alarm condition is detected on any input.
