Abstract

A multi-parameter patient monitoring device rack can dock a plurality of patient monitor modules and can communicate with a separate display unit. A signal processing unit can be incorporated into the device rack. A graphics processing unit can be attached to the display unit. The device rack and the graphic display unit can have improved heat dissipation and drip-proof features. The multi-parameter patient monitoring device rack can provide interchangeability and versatility to a multi-parameter patient monitoring system by allowing use of different display units and monitoring of different combinations of parameters. A dual-use patient monitor module can have its own display unit configured for displaying one or more parameters when used as a stand-alone device, and can be docked into the device rack when a handle on the module is folded down.

Claims

1-41. -41. (canceled)

42. A processing unit of a multi-parameter patient monitoring system with improved heat dissipation, the processing unit comprising:

a housing unit including a front side, a back side, and a side surface extending between the front and back sides, the housing unit comprising one or more first vent openings and one or more second vent openings, the one or more first vent openings and the one or more second vent openings located substantially on opposite ends of the housing unit, wherein the housing unit comprises an outer component and an inner component, the inner component located at least partially within the outer component;

one or more hardware processors within the housing unit; and

a fan within in the housing unit, wherein, when activated, the fan draws pressurized air into the one or more first vent openings, the pressurized air flowing over the one or more hardware processors before exiting the housing unit via the one or more second vent openings,

wherein at least one of the one or more first vent openings or the one or more second vent openings are located on the inner component, a portion of the outer component extending over the at least one of the one or more first vent openings or the one or more second vent openings and an inner wall of the portion of the outer component being separated from the at least one of the one or more first vent openings or the one or more second vent openings by a gap so as to substantially shield the at least one of the one or more first vent openings or the one or more second vent openings from liquid drops without substantially impeding the pressurized air from flowing across the at least one of the one or more first vent openings or the one or more second vent openings.

43. The processing unit of claim 42, wherein the housing unit is generally rectangular.

44. The processing unit of claim 42, wherein, when in use, a top surface of the housing unit is sloped and/or has a curvature so as to allow liquid drops falling onto the top surface of the housing unit to slide off in a trajectory away from the one or more first vent openings and/or the one or more second vent openings.

45. The processing unit of claim 42, wherein the fan is located closer to the one or more second vent openings than to the one or more first openings.

46. The processing unit of claim 42, wherein the housing unit comprises a docking station configured to receive a plurality of patient monitor modules, the docking station being proximate the one or more first vent openings.

47. The processing unit of claim 46, wherein at least one of the plurality of patient monitor modules comprises a patient module signal processing unit, the pressurized air configured to flow over the patient module signal processing unit when the at least one of the plurality of patient monitor modules is docked in the docking station.

48. The processing unit of claim 47, wherein the one or more first vent openings comprise a plurality of slits on the inner compartment, the plurality of slits being underneath the plurality of patient monitor modules that are docked in the docking station when the processing unit is in use.

49. The processing unit of claim 42, wherein the one or more processors comprise one or more graphics processors, the one or more graphics processors configured to communicate with a second processing unit of the multi-parameter patient monitoring system to receive values of the one or more physiological parameters, the second processing unit located in a device rack of the multi-parameter patient monitoring system, the device rack being separate from the housing unit.

50. The processing unit of claim 49, wherein the outer component of the housing unit comprises an outer shell extending around a side surface of the inner component, the one or more first and second vent openings located on the inner component.

51. The processing unit of claim 50, wherein a top surface of the outer shell has a slope and/or curvature such that liquid drops onto the processing unit are directed in a trajectory away from the one or more first and second vent openings by the outer shell.

52. The processing unit of claim 50, wherein an inner surface of the outer shell is spaced from the one or more first and second vent openings on the inner component by the gap.

53. The processing unit of claim 49, wherein the processing unit is mounted on a display device and in electrical communication with the display device.
