Abstract

A ventilator system (110) includes: an inhalation filter (120) configured to receive and filter a gas; a humidifier (130) connected to the inhalation filter and configured to adjust a humidity of the filtered gas; a dual-limb patient circuit connected to a patient and configured to supply ventilation to the patient, the dual limb patient circuit including an inspiratory limb connected to the humidifier and configured to supply the filtered gas to the patient and an expiratory limb configured to receive an exhaled gas from the patient; a condenser (140) connected to the expiratory limb, the condenser being configured to cool and remove moisture from the gas from the patient; and an expiratory filter (150) connected to the condenser and configured to filter the cooled gas from the condenser.

Description

field of invention [0001] The present invention relates to patient ventilator systems and devices, and in particular, to a thermal cooler and dehumidifier for the expiratory path of a ventilator system and a ventilation system incorporating such a thermal cooler and dehumidifier. Background technique [0002] Ventilators are used in various settings. For example, in a hospital, patients may be ventilated as part of their medical care. In particular, ventilators are commonly provided in hospital intensive care units (ICUs). [0003] An expiratory filter is a filter for filtering exhaled gas from a patient in the expiratory limb of a dual limb patient circuit used with a ventilator. The purpose of the filter is to reduce cross contamination of the ventilator between patients. For example, the bacterial and viral filtration efficiencies of such exhalation filters are specified according to NIOSH (eg, N100 filters remove 99.97% of particles in exhaled air). [0004] In gener...
