Abstract

According to the present disclosure, a CPAP apparatus that has a humidification function and that has high portability is provided. A CPAP apparatus includes a body unit and a base unit on and from which the body unit is mountable and removable. The body unit includes a first housing that has a first inlet and a first outlet, an air-sending device that discharges, via the first outlet, air that is introduced via the first inlet, and a first control unit that controls the air-sending device. The base unit includes a second housing that has a second inlet and a second outlet, a humidifier that humidifies air that is introduced via the second inlet, and a second control unit that controls the humidifier.

First claim

1 . A continuous positive airway pressure (CPAP) apparatus that delivers air sucked in the apparatus to an airway of a user, the CPAP apparatus comprising:
a body; and a base on which the body is mountable, and from which the body is removable, wherein the body comprises a first housing that has a first inlet and a first outlet, a blower configured to discharge, via the first outlet, air that is introduced via the first inlet, and a first controller configured to control the blower, wherein the base comprises a second housing that has a second inlet and a second outlet, a humidifier configured to humidify air that is introduced via the second inlet, and a second controller configured to control the humidifier, wherein, when the CPAP apparatus is in a first use state in which the body is mounted on the base, the second inlet is connected to the first outlet, and a tube through which air is supplied to the user is connected to the second outlet, and wherein, when the CPAP apparatus is in a second use state in which the body is not mounted on the base, the tube is connected to the first outlet.

2 . The CPAP apparatus according to claim 1 , wherein the first controller and the second controller are digitally connected to each other and are configured to receive digital signals from each other.

3 . The CPAP apparatus according to claim 1 ,
wherein the body further comprises a first temperature sensor that has an analog connection to the first controller, and that is configured to detect a temperature of air that is introduced into the first housing by the blower, and wherein when the CPAP apparatus is in the first use state, the first controller is configured to report a first temperature that is detected by the first temperature sensor to the second controller, and the second controller is configured to control the humidifier based on the first temperature that is received from the first controller.

4 . The CPAP apparatus according to claim 1 ,
wherein the second housing has a third inlet and a third outlet that is connected to the first inlet when the CPAP apparatus is in the first use state, and wherein the base further comprises a first temperature sensor that has an analog connection to the second controller, and that is configured to detect a temperature of air that is introduced into the second housing via the third inlet by the blower, and wherein when the CPAP apparatus is in the first use state, the second controller is configured to control the humidifier based on a first temperature that is detected by the first temperature sensor.

5 . The CPAP apparatus according to claim 3 ,
wherein the humidifier comprises a container that is configured to store water, a heater that is configured to heat the water in the container, and a second temperature sensor that is configured to detect a heater temperature of the heater, and wherein the second controller is configured to set a target heater temperature based on the first temperature, and to control the heater such that the heater temperature that is detected by the second temperature sensor becomes equal to the target heater temperature.

6 . The CPAP apparatus according to claim 4 ,
wherein the humidifier comprises a container that is configured to store water, a heater that is configured to heat the water in the container, and a second temperature sensor that is configured to detect a heater temperature of the heater, and wherein the second controller is configured to set a target heater temperature based on the first temperature, and to control the heater such that the heater temperature that is detected by the second temperature sensor becomes equal to the target heater temperature.

7 . The CPAP apparatus according to claim 1 ,
wherein the body further comprises a pressure sensor that is configured to detect a pressure of air that is discharged by the blower, and a flow rate sensor that is configured to detect a flow rate of air between the blower and the tube, and wherein the first controller is configured to control the blower based on a value of the pressure that is detected by the pressure sensor, and a value of the flow rate that is detected by the flow rate sensor.

8 . The CPAP apparatus according to claim 7 ,
wherein the second controller is configured to communicate with an additional device that is configured to detect a state of the user, and to transmit state information to the first controller, the state information representing the state of the user that is detected by the additional device, and wherein the first controller is configured to control the blower based on the value of the pressure, the value of the flow rate, and the state information.
