Modular multi-parameter patient monitoring device

A processing unit of a multi-parameter patient monitoring system with improved heat dissipation, the 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 on opposite ends of the housing unit, 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 at least one of the one or more first vent openings or the one or more second vent openings;
• 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 housing unit via 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.

A device rack of a multi-parameter patient monitoring system with improved heat dissipation, the device rack configured to electrically communicate with a graphics processing unit separate from the device rack, the device rack comprising:

• a device rack housing having a front side, a back side, and a side surface extending between the front and back sides, the back side comprising a plurality of vent openings;
• a dock housing comprising a plurality of docks configured to receive a plurality of patient monitor modules, the plurality of patient monitor modules each configured for connecting to one or more sensors so as to measure one or more physiological parameters, wherein the dock housing is located in a first portion of the device rack housing and is spaced apart from an inner wall of the device rack housing to define a gap, the dock housing comprising a plurality of vent openings adjacent to the gap;
• a processor unit configured to receive and process data from the plurality of patient monitor modules, wherein the processor unit is located in a second portion of the housing;
• and
• a fan located in the second portion of the housing and at or near the plurality of openings on the back side, wherein, when activated, the fan is configured to draw pressurized air into the gap, the pressurized air flowing over the processor unit before exiting through the plurality of vent openings on the back side.
