VARS (Vacuum Assisted Relief System) is a aircrew bladder relief system that allows the pilot, whether male or female, to urinate in flight with comfort and convenience. There are three principle parts to the system, The pump, the garment, and the receiver. A pump and battery pack may be mounted in a breast pocket or attached to a torso harness at breast level. Locating the pump at a level higher than the garment insures little or no “leak back” to the garment. A garment worn like a diaper or underwear, includes an intake manifold comprised of a number of perforated tubes sandwiched between layers of material. Urine from a user is collected in the garment, drawn into the manifold tubes through these holes, by means of vacuum from the pump. Collected urine then passes through a hose into containment bag or receiver.
