| abstract |
An anesthesia rebreathing system (30) including a single use structural portion (56) and a reusable structural portion (50, 52, 54) configured so as to be readily latched together to automatically couple respective fresh gas interface ports (103, 105) and patient overflow ports (108). The single use portion (56) includes a patient bag (66) which is mounted in a closed rigid container (52) in the reusable portion (50, 52, 54). Gas pressure in the container is controlled by an anesthetist squeezing an outside bag (54) or by a mechanical ventilator (36), as determined by the setting of a user operable control knob subassembly (70), which also functions to establish gas pressure and volume in both the patient circuit and the control circuit. |
