Patent ID: 7913332

Claim:
An apparatus to be disposed about a bed for regulating air freshness and temperature about at least one bed occupant disposed under at least one bed covering by drawing air in a directional flow about a body of the at least one occupant, said apparatus comprising: a. at least one extraction device means located under the at least one bed covering and proximate to the at least one bed occupant comprising flatus sensing means to automatically increase airflow in the presence of flatus; b. a vacuum means to provide air pressure negative to ambient about the bed for drawing air; c. a conduit in communication between the at least one extraction device means and the vacuum means to direct negative pressure from the vacuum means to the at least one extraction device means; d. a remote control means for regulation of airflow; e. a temperature sensing and control means to automatically increase or decrease airflow to maintain a temperature setpoint about the occupant's body under the bed covering; f. twin supports that attach to the each extraction device means; g. a bed sheet tensioning device to apply tension to at least one bed covering to ensure retention of a tented channel through which air is withdrawn about each bed occupant, said bed sheet tensioning device further comprising: h. an anchor strap that spans atop surface of the mattress support, upon the anchor strap the mattress lies; i. one or more anchor brackets that secure the anchor strap to the mattress support; j. a tensile band having two ends; k. two or more clips; l. at least one clip attached to a first end of the tensile band; m. at least one clip attached to a second end of the tensile band; and n. the tensile band being affixed to the anchor strap at an anchor point between each clip location wherein elasticity of the anchor strap is negligible relative to elasticity of the tensile band and wherein either end of the tensile band retracts toward the anchor point and the retracted length of the tensile band is less than a width of the mattress, and wherein the twin supports that attach to the each extraction device means are held proximate to a top surface of a mattress, the twin supports having thin flat feet that slide between the mattress and a supporting bed structure to hold in position the each extraction device means without contact with each occupant body by the each extraction device means.
