Abstract
A respiratory assistance device including a respiratory interface device configured to be worn by a user and deliver a gas, a gas temperature measurement unit configured to measure a gas temperature that is a temperature of the gas, a warming unit configured to warm the gas, and a temperature change unit configured to change the gas temperature by controlling the warming unit. The respiratory assistance device can administer comfortable respiratory assistance even during sleep.
Claims13
A respiratory assistance device capable of humidifying a gas comprising:
- a respiratory interface device configured to be worn by a user and deliver a gas;
- a gas temperature measurement unit configured to measure a gas temperature that is a temperature of the gas;
- a warming unit configured to warm the gas;
- an outside air temperature measurement unit configured to measure an outside air temperature that is a temperature of a place where the user is;
- a temperature change unit configured to change the gas temperature by controlling the warming unit;
- wherein the temperature change unit includes a timer processing unit configured to control the gas temperature according to a lapse of time;
- wherein the temperature change unit controls the warming unit to maintain the temperature of the gas at or above a body surface temperature of the user for a predetermined time after the user starts running the respiratory assistance device;
- and
- wherein the outside air temperature is defined as Tout (in units of degrees Celsius), and the temperature change unit controls the warming unit to decrease the gas temperature to a target temperature between Tout and (Tout−10) after a lapse of the predetermined time.
