A dew point sensor system contains a controller (22) with a dew point calculator, an ambient temperature sensor (20), an air pathway (52), a heater plate (32), and an external wire (60). The ambient temperature sensor (20) generates ambient temperature data, and the ambient temperature sensor (20) is operatively-connected to the controller (22). The air pathway (52) contains a blower (38) within the air pathway (52), an air flow sensor (26) within the air pathway (52), a liquid reservoir (56) operatively-connected to the air pathway (52), and component which may be an air pathway temperature sensor (28) and / or a breathing circuit heating element. The blower (38) causes air to move in the air pathway (52), while the air flow sensor (26) generates air flow data about the air moving in the air pathway (52). The heater plate (26) contains a heater plate temperature sensor (34), and the heater plate temperature sensor (34) generates heater plate temperature data. An external wire (60) is operatively-connected to the controller (22) and the component. The ambient temperature sensor (20) is located on the external wire (60). The heater plate (26), and the heater plate temperature sensor (34) are operatively-connected to the controller (22), and the controller (22) receives the ambient temperature data, the air flow data, and the heater plate temperature data to calculate the target heater plate temperature, based on the dew point temperature. A method of modulating a humidifier heater plate, a humidifier, and a medical device may also include the dew point sensor system.
Description
technical field [0001] The present invention relates to dew point sensor systems and machines incorporating such dew point sensor systems, such as humidifiers. More specifically, the present invention relates to dew point sensor systems including ambient temperature sensors. [0002] technical background [0003] Humidifiers are used to provide humidified air to users, usually patients in hospitals, hospice, or even at home. Humidifiers typically operate under a variety of conditions, ranging from about 10°C to about 40°C and above. It is well known that the amount of water that air may contain depends on the temperature of the air, whereby a distinction is made between relative humidity and absolute humidity. [0004] Accordingly, humidifiers that measure ambient air temperature are known, as in, for example, U.S. Patent No. 8,616,202 B2, Fisher & Paykel Healthcare Ltd., published Dec. 31, 2013; and Fisher & Paykel Healthcare, Inc., published Aug. 28, 2018. Ltd. as seen i...
