Electronic patient diary and patient monitoring process
First Claim
1. A portable electronic health care diary, adapted to be carried about by the patient, for recording the duration and characteristics of periodic health condition episodes, such as angina attacks, which comprises(a) a microprocessor system including an accessible memory and a continuous clock/calendar,(b) first patient-operable control means adapted when actuated by the patient to cause said microprocessor to record in said memory an "onset" code, including the time and date of such actuation,(c) second patient-operable control means adapted when actuated by the patient to cause said microprocessor to record in said memory a "termination" code, including the time and date of such actuation,(d) third patient-operable control means effective only after operation of said second control means and adapted when actuated by the patient to cause said microprocessor to generate and record in said memory an additional code signifying the patient'"'"'s subjective evaluation of the characteristics of the episode recorded by said "onset" and "termination" codes,(e) means providing for periodic retrieval of the data recorded in said accessible memory to enable analysis of the timing, frequency and characteristics of said episodes,(f) said third patient-operable control means comprising an adjustable element for generating a signal indicating characteristics of the episode and switch-type control means for causing said microprocessor to record said characteristics.

Abstract
An electronic health care diary is provided for a patient logging data concerning predetermined health conditions, such as for monitoring angina attacks. Upon the onset of e.g. the angina attack the patient presses a start button whereupon a real time clock generates a data and time signal which is stored in a memory along with the fact that the episode started. When the episode is over the patient presses a "stop" switch which generates another date and time signal from the real time clock and stores it in memory along with the fact that the episode terminated. A multi-position switch is actuated by the patient to indicate the extent of the condition, such as the severity of the attack. Optionally, a switch can be provided for correcting a previous erroneous entry, and another switch indicating the time and dosage of any medication. Data logged in the memory can be downloaded through a communications port and programming instructions can be uploaded into the device. An appropriate display provides various messages for the user.
