Abstract
Abstract A monitor device electronically connected to a pacemaker and to an alarm device counts the pulses supplied to the heart by the pacemaker, detects the signal level of the pulses and compares the number of pulses with a preselected number and the signal level with a preselected signal level. The monitor device connects an auxiliary battery source of power to the pacemaker and actuates the alarm device when the detected number is less than the preselected number and when the detected level is less than the preselected level.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A pacemaker monitor for a pacemaker of a human heart, such pacemaker having an input, a primary battery source of power electrically connected to its input, and an output electrically connected to the heart of a user, said pacemaker monitor comprising an auxiliary battery source of power; switch means electrically connecting the auxiliary battery source of power to the input of the pacemaker; an alarm device; and a monitor device having inputs electrically connected to the output of the pacemaker and outputs electrically connected to the switch means and to the alarm device for counting the pulses supplied to the heart by the pacemaker, detecting the signal level of such pulses and comparing the number of pulses with a preselected number and the signal level with a preselected signal level and closing the switch means to connect the auxiliary battery source of power to the pacemaker and actuating the alarm device when the detected number is less than the preselected number and when the detected level is less than the preselected level.
Claim 2
Dependent Claim
172 words
A pacemaker monitor for a pacemaker of a human heart, such pacemaker having an input, a primary battery source of power electrically connected to its input, and an output electrically connected to the heart of a user, said pacemaker monitor comprising an auxiliary battery source of power; switch means electrically connecting the auxiliary battery source of power to the input of the pacemaker; an alarm device; and a monitor device having inputs electrically connected to the output of the pacemaker and outputs electrically connected to the switch means and to the alarm device for counting the pulses supplied to the heart by the pacemaker, detecting the signal level of such pulses and comparing the number of pulses with a preselected number and the signal level with a preselected signal level and closing the switch means to connect the auxiliary battery source of power to the pacemaker and actuating the alarm device when the detected number is less than the preselected number and when the detected level is less than the preselected level.
Claim 3
Dependent Claim
23 words
A pacemaker monitor as claimed in claim 1, wherein the auxiliary battery source of power is external to the body of the user.
Claim 4
Dependent Claim
