Abstract

Certain embodiments herein relate to a physiological parameter monitoring system. The system may include a sensor and sensor electronics connectable to the sensor. The system may also include a transmitter operably connected to the sensor electronics, the transmitter having or being configured to have at least a portion thereof positioned at a first location adjacent to and/or in contact with an external surface of a body of a host during a sensor session, the transmitter further configured to wirelessly transmit sensor information using human body communication. The system may further include a first display device comprising a display and a receiver, the receiver having or being configured to have at least a portion thereof positioned at a second location adjacent to and/or in contact with the external surface of the body during the sensor session, the receiver further configured to receive sensor information from the transmitter using human body communication.

First claim

What is claimed is:

1. A physiological parameter monitoring system comprising:
a transcutaneous or subcutaneous sensor configured to generate a sensor output signal;
sensor electronics connected or connectable to the sensor with a wired connection;
a primary sensor information transmitter connected or connectable to the sensor electronics with a wired connection, the primary sensor information transmitter having or being configured to have at least a portion thereof positioned at a first location adjacent to and/or in contact with the epidermis of a body of a host during a sensor session, the primary sensor information transmitter further configured to wirelessly transmit sensor information generated by or derived from the sensor output signal using human body communication;
a relay module comprising:
a primary sensor information receiver, the primary sensor information receiver having or being configured to have at least a portion thereof positioned at a second location adjacent to and/or in contact with the epidermis of the body of the host during the sensor session, the primary sensor information receiver further configured to wirelessly receive the sensor information from the primary sensor information transmitter using human body communication, and
a secondary sensor information transmitter connected or connectable to the primary sensor information receiver with a wired connection and configured to wirelessly transmit sensor information previously received by the primary sensor information receiver from the primary sensor information transmitter; and
a first display device comprising a display and a secondary sensor information receiver configured to wirelessly receive the sensor information from the secondary sensor information transmitter, wherein:
the first display device is further configured to send a power signal to the relay module for powering the relay module; and
the relay module is configured to relay the power signal to the sensor electronics for powering the sensor electronics.

2. The system of claim 1 , wherein the secondary sensor information transmitter and the secondary sensor information receiver both comprise Bluetooth modules.

3. The system of claim 2 , wherein the second location is a wrist of the host.

4. The system of claim 1 , wherein the first display device comprises a smartphone.

5. A physiological parameter monitoring system comprising:
a sensor configured to generate a sensor output signal;
sensor electronics connected or connectable to the sensor with a wired connection;
a first primary sensor information transmitter connected or connectable to the sensor electronics with a wired connection and configured to wirelessly transmit first sensor information generated by or derived from the sensor output signal using human body communication;
a second primary sensor information transmitter connected or connectable to the sensor electronics with a wired connection and configured to wirelessly transmit second sensor information generated by or derived from the sensor output signal;
a first display device comprising a display and a first primary sensor information receiver configured to wirelessly receive the first sensor information from the first primary sensor information transmitter using human body communication; and
a second display device comprising a display and a second primary sensor information receiver, wherein:
the second display device different from the first display device;
the second primary sensor information receiver is configured to wirelessly receive the second sensor information from the second primary sensor information transmitter via a communication protocol different from human body communication; and
the second primary sensor information transmitter is configured to wirelessly transmit the second sensor information to the second primary sensor information receiver upon a determination that the first primary sensor information receiver did not receive the first sensor information.

6. The system of claim 5 , wherein the second primary sensor transmitter and the second primary sensor information receiver both comprise a Bluetooth module.

7. A physiological parameter monitoring apparatus comprising:
a sensor configured to generate a sensor output signal relating to a host;
sensor electronics operably connected or connectable to the sensor; and
a transmitter operably connected or connectable to the sensor electronics, the transmitter comprising:
a first conductive contact positioned on a first side of the sensor electronics and operably connected to the sensor electronics; and
a second conductive contact positioned on a second side of the sensor electronics and operably connected to the sensor electronics, wherein:
the sensor electronics is configured to apply a signal across the first and second conductive contacts to wirelessly transmit sensor information generated by or derived from the sensor output signal using human body communication;
the sensor electronics, the first conductive contact, and the second conductive contact are affixed to a common substrate; and
the common substrate comprises:
a first predetermined thickness for providing a first offset between the first conductive contact and a tissue of the host; and
a second predetermined thickness for providing a second offset between the second conductive contact and the tissue of the host, the second predetermined thickness different from the first predetermined thickness.

8. The apparatus of claim 7 , wherein the common substrate comprises an adhesive or printed circuit board (PCB).

9. The apparatus of claim 7 , wherein the sensor electronics is positioned between the first conductive contact and the second conductive contact.

10. The apparatus of claim 7 , wherein the first conductive contact comprises a metal plate that is or is configured to be capacitively coupled to the epidermis of the host.

11. The apparatus of claim 7 , wherein the second conductive contact comprises a metal plate that is or is configured to be capacitively coupled to the epidermis of the host.

12. The apparatus of claim 7 , wherein the first conductive contact is covered with a first insulating film and wherein the second conductive contact is covered with a second insulating film.

13. The apparatus of claim 12 , wherein the first insulating film is thinner than the second insulating film.
