Wireless ECG system
View Patent ↗A wireless monitoring system and, more particularly, a wireless monitoring system for detecting and transmitting physiological data. The present invention detects physiological data relating to a patient's cardiac activity and respiration rate and transmits the data to a remote base station via telemetry. The base station processes the data so that the data can be display by an ECG monitor.
1. A system for transmitting data comprising:
a chest assembly comprising at least a first electrode connector and a second electrode connector configured to couple electrodes to traces that run along the chest assembly;
a discrete body electronics unit separable from the chest assembly, the chest assembly being removably connected proximate to and in electrical contact with the body electronics unit, wherein the body electronics unit acquires physiological data from the chest assembly and wirelessly transmits the physiological data;
a plurality of base stations for receiving the physiological data transmitted from the body electronics unit, each base station capable of being simultaneously paired to the body electronics unit by activation of a switch on the body electronics unit and then pairing the body electronics unit with the plurality of base stations such that each of the base stations is enabled to receive physiological data transmitted by the body electronics unit, each base station comprising a plurality of terminals for transmitting the physiological data to a monitor.
2. The system of claim 1 , wherein the physiological data is transmitted from the body electronics unit to the plurality of base stations using two-way communication.
3. The system of claim 1 , wherein the body electronics unit is configured to transmit non-physiological data to each base station.
4. The system of claim 3 , wherein the physiological data corresponds to a patient's respiration rate and cardiac activity and the non-physiological data corresponds to pacemaker pulse data.
5. The system of claim 1 , wherein each base station is configured to transmit non-physiological signals to the body electronics unit.
6. The system of claim 1 , wherein the body electronics unit is configured to continuously transmit physiological data to a first base station and to simultaneously transmit physiological data to a second base station for a temporary amount of time.
7. The system of claim 1 , wherein the chest assembly further comprises:
a base layer having a first side and a second side, wherein the first side contains a plurality of electrically conductive elements, the electrically conductive elements configured to be removably coupled to electrodes, the base layer positioned between a first insulating layer and a second insulating layer.
8. The system of claim 7 , wherein the chest assembly further comprises a plurality of electrode housings, each electrode housing positioned over an aperture formed in the chest assembly and containing an elastomeric portion defining a female void for receiving a portion of an electrode.
9. The system of claim 8 , wherein the aperture forms at least one flap for engaging an electrode positioned through the aperture.
10. The system of claim 7 , wherein the chest assembly further comprises a plurality of electrode housings, each electrode housing positioned over an aperture formed in the chest assembly and containing an elastomeric portion defining a female void for receiving a conductive member configured to be coupled to an electrode.
11. The system of claim 10 , wherein the aperture forms at least one flap for engaging an electrode positioned through the aperture.
12. The system of claim 7 , wherein the chest assembly further comprises a plurality of electrode housings, each electrode housing positioned over an aperture formed in the chest assembly and containing a male conductive connector configured to be coupled to an electrode.
13. The system of claim 12 , wherein the aperture forms at least one flap for engaging an electrode positioned through the aperture.
14. The system of claim 1 , wherein the body electronics unit may be paired to any base station immediately preceding transmission of physiological data from the chest assembly to the base station.
15. The system of claim 1 further comprising at least one battery configured for use with both the body electronics unit and the base station, wherein the base station is capable of charging the battery.
16. The system of claim 15 further comprising a second battery configured to be interchangeable with the first battery, wherein the batteries can be swapped between the body electronics unit and the base station.
17. The system of claim 15 , wherein the battery contains an indicator for monitoring the charge of the battery.
18. The system of claim 1 , wherein the base station is contained within the monitor.
19. The system of claim 1 , wherein an alarm signal is transmitted from the body electronics unit to the base station upon the detection of a fault condition in the first electrode, the second electrode, or the body electronics unit.
20. The system of claim 1 , wherein an alarm signal is transmitted from the base station to the body electronics unit upon the detection of a fault condition in the base station.
