Abstract

A patient monitoring system is provided which includes a platform and one or more monitoring modules. Monitoring modules include parameter modules for monitoring physiological activity of a patient, and utility modules for providing additional functionality to the patient monitoring system. A platform and one or more monitoring modules may be coupled to form a communications bus, allowing communication between any of the plurality of coupled devices. Updates such as software upgrades may be provided by a monitoring module to a platform or other monitoring module to update functionality.

Claims

1. A monitoring module comprising:

a memory storing update information;

a connection interface;

a communications bus coupled to the memory and to the connection interface, wherein the connection interface is capable of being mated to a platform, and wherein the monitoring module is configured to update the platform using the communications bus to communicate the update information to the platform; and

a sensor interface configured to take as input a physiological signal from a sensor coupled to the sensor interface.

2. The monitoring module of claim 1, wherein the monitoring module is a first monitoring module, and wherein the first monitoring module is further configured to update the platform to be capable of communicating with a second monitoring module the platform would otherwise be incapable of communicating with.

3. The monitoring module of claim 1, wherein the monitoring module is a first monitoring module and wherein the first monitoring module and a second monitoring module are coupled to the platform simultaneously.

4. The monitoring module of claim 1, wherein the monitoring module comprises a communications interface coupled to an information source, and wherein the monitoring module is configured to receive the update information from the information source.

5. The monitoring module of claim 4, wherein the communications interface comprises an internal bus, and wherein the information source comprises an expansion card communicatively coupled to the monitoring module using the internal bus.

6. The monitoring module of claim 1 further configured to couple with the platform in a stacking arrangement.

7. A patient monitoring system platform comprising:

a chassis;

a user interface;

a processor coupled to the user interface;

a communications bus coupled to the processor; and

a platform connection interface coupled to the communication bus, wherein the chassis is capable of mating with a first monitoring module such that a monitoring module connection interface is coupled to the platform connection interface, and wherein the communications bus is capable of being communicatively extended to other monitoring modules that are coupled in series to one another and to the first monitoring module such that the first monitoring module and a second monitoring module are coupled to the platform connection interface simultaneously, and wherein the processor is configured to process update information received from the first monitoring module and the other monitoring modules to update the patient monitoring system platform.

8. The patient monitoring system platform of claim 7 wherein any of the monitoring modules are removable.

9. The patient monitoring system platform of claim 7 wherein the chassis and platform connection interface are arranged such that mating a monitoring module to the chassis results in a stacked arrangement.

10. The patient monitoring system platform of claim 7 wherein the monitoring modules comprise at least one parameter module.

11. The patient monitoring system platform of claim 7 wherein the monitoring modules comprise at least one utility module.

12. The patient monitoring system platform of claim 7 wherein the processor is configured to process physiological parameter information received from the monitoring modules and the first monitoring module.

13. The patient monitoring system platform of claim 12 wherein the user interface is a display interface configured to display data based at least in part on the physiological parameter information.

14. The patient monitoring system platform of claim 12 further comprising a network interface capable of communicating with a remote monitoring station.

15. A method for updating a platform of a patient monitoring system, the method comprising:

coupling a monitoring module to the platform; and

updating the platform by communicating update information to the platform from the monitoring module using a communications bus, and wherein the updating the platform comprises configuring the platform to communicate with a monitoring module the platform is otherwise unable to communicate with.

16. The method of claim 15, further comprising detecting a device using the communications bus.

17. The method of claim 15, wherein the updating the platform comprises performing a function selected from the group consisting of providing an application for processing an output of a monitoring module, updating software of the platform, updating preference information, updating communication instructions, updating templates of the platform, updating settings of the patient monitoring system, and a combination thereof

18. The method of claim 15, further comprising receiving update information at the monitoring module from an information source.

19. A first monitoring module comprising:

a memory storing update information;

a connection interface; and

a communications bus coupled to the memory and to the connection interface, wherein the connection interface is capable of being mated to a platform, and wherein the first monitoring module is configured to update the platform using the communications bus to communicate the update information to the platform, and wherein the first monitoring module and a second monitoring module are coupled to the platform simultaneously.
