Intended Use: The Model 3810A is intended to be used upon prescription of a licensed physician or authorized healthcare provider by patients as a means to automatically collect and transmit medical information, such as weight, blood pressure and non-diagnostic ECG, over normal residential telephone lines, between a patient, typically at home, and a health care professional at the authorized provider. Indications for Use: The Model 3810A is indicated for patients at home, who are capable and willing self-administrate this device, upon prescription of their healthcare provider, to collect and transmit medical information such as weight, blood pressure (including pulse rate) and non-diagnostic ECG rhythm strip to the healthcare provider at another location. The patient takes these measurements, typically once per day, and the information is transmitted automatically via normal telephone lines to the healthcare provider. The device does not send any real-time alarms. Clinical judgement and experience are required to check and interpret the information delivered.

The Hewlett-Packard (HP) Model 3810A telemedicine device provides a system for daily collection of weight, blood pressure and ECG used in the management of home care patients. The main flow of information originates in the home where a patient uses a blood pressure unit, a scale and an ECG rhythm recorder on a daily schedule. Each of the units automatically reports their data wirelessly to a home Hub, which in turn relays the data using a standard modem over the telephone to a secure database. Health care professionals (such as physicians, nurses, and case managers) having approval for access use a secure log-on procedure to gain access to their patient's data. The provider follows up on any unexpected or undesired changes in the patient's data trends with a phone call. The home Hub incorporates a receiver, an embedded processor with memory, a standard modem and an automatic dial up module. It is designed so that its operation does not interfere with normal use of the phone including an answering machine. Its connections are identical to those of an answering machine, consisting of a standard wall power plug and a daisy chain phone connection. The installation and use of the home Hub poses no significant risk to the patient or other people within the patient's home. The data forwarded through the home Hub arrives though a standard modem contained in the HP system server. This server is separate from the Telemedicine PC in the clinic and is programmed to decode the data from the home units. The system design provides for data security.
