Abstract

A system for patient monitoring includes a plurality of components including a monitor and display assembly, optional stand-alone displays, optional stand-alone monitors, one or more modules, and at least one patient parameter measuring device. The display includes a flat glass front with a blackened border that appears continuous but allows the passage of light during alarm situations. The display functions as a touchscreen and includes a portion for alarm volume control. The system also includes a docking station for the monitor and display assembly and capnography and/or multigas pods for attachment to the monitor and display assembly. The monitor and display assembly, docking station, and pods enhance portability of the system. The monitor and display assembly, module(s), and patient parameter measuring device(s) are all interconnected via Dual Serial Bus (DSB) interfaces.

Claims

1. A system for patient monitoring comprising:

at least one patient monitor that allows for communication with external devices, wherein said patient monitor is in electronic communication with and drives at least one display, and wherein said display comprises;

a housing having a front and a back;

a touchscreen mounted to the front of said housing, wherein said touchscreen comprises a flat piece of glass having a central display area and a black border that extends along a left, right, top, and bottom edge of said glass, further wherein said monitor is fixedly attached to said back of said display;

at least one module for providing measurements of a plurality of patient parameters, wherein said module is in electronic communication with said patient monitor and wherein said module comprises at least one interface for electronically communicating with at least one patient parameter measurement device;

a processor for determining an alarm state; and

, light sources within said touchscreen which are activated by said processor during the alarm state, wherein said light sources are configured to pass through said black border; and

at least one Dual Serial Bus (DSB) interface for enabling electronic communication between the patient monitor, module, and/or patient parameter measuring device.

2. The system for patient monitoring of claim 1, wherein at least one light source is positioned proximate said top edge of said front face of said display device.

3. The system for patient monitoring of claim 2, wherein said touchscreen comprises an area corresponding to said light source for controlling alarm volume level.

4. The system for patient monitoring of claim 3, wherein said area comprises a first portion for decreasing said alarm volume level and a second portion for increasing said alarm volume level.

5. The system for patient monitoring of claim 1, wherein at least one light source is positioned on said rear face of said display.

6. The system for patient monitoring of claim 1, wherein said at least one patient monitor comprises a removable internal chassis for mounting a plurality of circuit boards.

7. The system for patient monitoring of claim 1, wherein said at least one patient monitor comprises a handle attached to said patient monitor and wherein said handle further comprises an up and a down position, a set-point for balancing said patient monitor perpendicular to the floor when said patient monitor is carried using said handle and, a damper to retard downward motion of said handle when said handle is released from the up position.

8. The system for patient monitoring of claim 1, wherein said at least one patient monitor comprises Li-Ion batteries and a microcontroller for monitoring charging, discharging and over-temperature conditions of said batteries.

9. The system for patient monitoring of claim 8, wherein said at least one patient monitor is capable of operating 8 hours on battery power while monitoring ECG, NIBP every 15 minutes and taking a recording every 15 minutes.

10. The system for patient monitoring of claim 9, wherein said at least one patient monitor weighs less than 9 pounds.

11. A docking station having a receiving surface to receive a monitor and display device of a patient monitoring system, said monitor and display device having a first connector and a first plurality of monitor receptacles for transmission of digital information and power, said docking station comprising:

a. a second plurality of receptacles;

b. a second connector positioned on said receiving surface of said docking station for mating with said first connector of said monitor and display device;

c. a circuit board for controlling said transmission of digital information and power;

d. a molded recess matching an external shape of a bottom portion of said monitor and display device;

e. at least one latching mechanism for securely holding said monitor and display device in place and,

f. a release button for disengaging said latching mechanism for removal of said monitor and display device from said docking station;

wherein, when said monitor and display device is securely mounted on said docking station via said latching mechanism, said first connector is in electrical communication with said second connector, further wherein said circuit board transfers said transmission of digital information and power away from said first plurality of receptacles, through said first and second connectors, and to said second plurality of receptacles.

12. The docking station of claim 11, wherein the said second plurality of receptacles comprises Ethernet connection, DVI for external display, USB, serial ports, external nurse alert/external audio/IR receiver, power and SDLC (synchronous data link control) port.

13. The docking station of claim 11, wherein said docking station covers said first plurality of receptacles on said monitor and display device when the said monitor and display device is docked in the docking station.

14. The docking station of claim 11, wherein said monitor and display device further comprises a first plurality of vents and said docking station further comprises a second plurality of vents, said first and second plurality of vents aligning when said monitor and display device is mounted in said docking station.

15. The docking station of claim 11, wherein said molded recess further comprises an outward bevel to guide the monitor and display device into position during docking.

16. The docking station of claim 11, further comprising at least one pin configured to fit at least one corresponding opening on said monitor and display device to further guide placement of said monitor and display device into said docking station.

17. The docking station of claim 11, wherein said release button is backlit when said monitor and display device is docked in said docking station.

18. An externally mountable pod for attaching to a monitor of a patient monitoring system, said pod comprising:

a. a plurality of pogo pins for mating with connectors on said monitor;

b. at least one guide pin for mating said pod with said monitor;

c. a latching mechanism for connecting and removing said pod to and from said monitor;

d. a button for actuating said latching mechanism; and

,

e. a plurality of receptacles on a side of said pod.

19. The pod of claim 18, wherein said pod is a sidestream capnography or multigas pod.

20. The pod of claim 18, wherein said plurality of pogo pins enable the pod to receive power from said monitor and enable communication between said pod and said monitor.
