The switch is a normally closed low pressure switch that remains open for as long as a patient's weight maintains an air pressure greater than the preset actuating pressure of the switch and closes when the patient's weight is removed and the pressure in the bag is thereby lowered, energizing a signal at the attendant's station. | InventorApplicationNo. 05/678460 filed on 04/19/1976US Classes:340/573.4, House arrest system, wandering, or wrong place200/85R, WEIGHT340/626, Pressure340/666, Weight5/940, WITH ALARM MEANS600/595Body movement (e.g., head or hand tremor, motility of limb, etc.)ExaminersPrimary: Swann, III, Glen R.US Patent References2260715, 2795668, 2818477, 3533095, 3974491Load signaling device for a patient's footIssued on: 08/10/1976 Inventor: Sipe International ClassA61G 12/00 (20060101) |
