Title:
CPAP DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/024573
Kind Code:
A1
Abstract:
The present disclosure provides a CPAP device in which it is possible to readily suppress air leakage from between flow paths of a first unit and a second unit. A blower is disposed in a main flow path 32 of a main unit 20 of a CPAP device 10. An upstream-side flow path 53 connected to the upstream side of the main flow path 32 is defined in a base unit 40. A sealing member 60 fixed to the base unit 40 of the CPAP device 10 has a ring shape surrounding a second outlet 47 from the outside. Furthermore, the opening of the sealing member 60 at the distal end in the extending direction has a shape surrounding a first inlet 23 from the outside. The dimension of the sealing member 60 in the extending direction is greater than the dimension of the sealing member 60 in the thickness direction. Furthermore, the dimension of the sealing member 60 in the extending direction is greater than the shortest distance D from the proximal end of the sealing member 60 in the extending direction to the main unit 20 in the state where the main unit 20 is attached to the base unit 40.
