Abstract

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 patients 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 displayed by an ECG monitor.

Claims

1. A chest assembly for collecting physiological data, comprising:

a one-piece flexible circuit comprising;

a substantially radiolucent base layer having a first side and a second side, said first side containing a plurality of substantially radiolucent electrical traces, said electrical traces configured to be coupled to a plurality of electrodes, said base layer disposed adjacent at least one electrically insulating layer;

at least one aperture formed in said base layer; and

at least one electrode housing disposed adjacent said aperture in said base layer and comprising a resilient portion defining a female void for receiving a portion of an electrode therein.

2. The assembly of claim 1 wherein said base layer is disposed between a first electrically insulating layer and a second electrically insulating layer.

3. The assembly of claim 1 wherein said electrical traces connect to at least one electrode connector and an assembly connector.

4. The assembly of claim 3 wherein each of said plurality of electrical traces form and define a separate electrode.

5. The assembly of claim 1 wherein the electrical traces are printed ink or anisotropic adhesive.

6. The assembly of claim 1 wherein the electrical traces are silver epoxy.

7. The assembly of claim 1 further comprising a substantially radiolucent shielding layer.

8. The assembly of claim 7 wherein said substantially radiolucent shielding layer comprises at least one layer of dielectric material.

9. The assembly of claim 1 wherein one side of the assembly further comprises a fabric layer.

10. The assembly of claim 1 wherein said aperture forms at least one flap for engaging and securing the male portion of an electrode positioned through the aperture.

11. The assembly of claim 1 wherein said female void accommodates a plurality of different sized male portions of conventional electrodes.

12. The assembly of claim 1 wherein said elastomeric member securely retains the male portions of conventional electrodes.

13. The assembly of claim 1 wherein said elastomeric member removably retains the male portions of conventional electrodes.

14. The assembly of claim 1 wherein the assembly connects to a telemetry transceiver via an adapter assembly.

15. The assembly of claim 1 wherein the assembly is directly connected to an electrocardiogram monitor via an adapter assembly.

16. The assembly of claim 1 wherein the assembly is disposable.

17. The assembly of claim 1 wherein the assembly connector comprises a sense pin for turning electronics on.

18. A radiolucent precordial assembly for collecting physiological data comprising:

a substantially radiolucent base layer having a first side and a second side, the first side attached to a plurality of radiolucent electrically conductive elements or traces, the electrically conductive elements or traces configured to be removably coupled to a plurality of precordial electrodes through a plurality of corresponding electrode connectors;

said electrically conductive elements disposed adjacent at least one electrically insulating layer, wherein the assembly comprises a plurality of contiguous arcuate sections wherein each electrode connector is contained at the end of an arc, thereby allowing flexible placement of the precordial electrodes.

19. The precordial assembly of claim 18 wherein the assembly further comprises a fabric layer.
