THE AIR INLET UNIT (120) HAS A GUIDING SLOT DIFFUSER (122) FOR GUIDING AN AIRSTREAM IN A CERTAIN DIRECTION, SUCH THAT A PATIENT (150), LYING DOWN IN A BED ON HIS BACK, RECEIVES THE AIRSTREAM FRONTALLY. THE EXHAUST UNIT (130) IS ARRANGED NEAR THE FLOOR (107) AND NEAR A HEAD END (141) OF THE BED (140) SUCH THAT AIR IS ARRANGED TO LEAVE THE ROOM AFTER HAVING VENTILATED THE PATIENT (150). THE AIR SUPPLY UNIT IS ALSO PROVIDED WITH A BOOSTER FAN (124) ARRANGED IN AIR COMMUNICATION WITH THE GUIDING SLOT DIFFUSER (122) SUCH THAT FRESH AIR CAN BE FORCED THROUGH THE DIFFUSER (124) BY THE AID OF THE BOOSTER FAN (124) FORMING A FIRST AN AIRSTREAM.
