Enhanced wireless communication for medical devices
First Claim
1. A method for collecting diagnostic data from a heart of a subject, comprising:
- (a) using a monitoring device comprising an ECG sensor and an audio sensor to measure ECG data and audio data from said heart of said subject;
(b) inserting both said ECG data and said audio data by said monitoring device into a common packet structure;
(c) transmitting said ECG data and audio data wirelessly to a computing device separate from said monitoring device using said common packet structure; and
(d) using said computing device to process said ECG data and audio data to provide an output indicative of said state or condition of said heart of said subject.

Abstract
Methods and apparatuses for wireless communication between medical devices are provided. In some embodiments, commodity low power, low bandwidth communication protocols may be utilized to simultaneously convey multiple signals with high fidelity and reliability. For example, cardiac sound data and ECG data may be compressed using a common ADPCM component and inserted into a common BLE packet structure. Command-control data may also be inserted. Where required command-control data reporting frequency is less than the packet frequency, header bits may be utilized to convey multiple types of command-control data in a given packet byte position. Rolling packet sequence values may be inserted into the common packet structure, for use by receiving devices to identify link integrity failures.
