Patent US 5,441,047

An ambulatory (in the home) patient health monitoring system is disclosed wherein the patient is monitored by a health care worker at a central station, while the patient is at a remote location. The patient may be a person having a specific medical condition monitored or may be an elderly person desiring general medical surveillance in the home environment. Cameras are provided at the patient's remote location and at the central station such that the patient and the health care worker are in interactive visual and audio communication. A communications network such as an interactive cable television is used for this purpose. Various medical condition sensing and monitoring equipment are placed in the patient's home, depending on the particular medical needs of the patient. The patient's medical condition is measured or sensed in the home and the resulting data is transmitted to the central station for analysis and display. The health care worker then is placed into interactive visual communication with the patient concerning the patient's general well being, as well as the patient's medical condition. Thus, the health care worker can make "home visits" electronically, twenty-four hours a day.
