Claims

[Scope of utility model registration request]

The flange at the entrance/exit of the main body of the hyperbaric oxygen therapy device and the flange at the end face of the door provided near the entrance/exit for opening/closing the entrance/exit are constructed in an overlapping manner with inside and outside having different diameters and face each other. A groove for accommodating a common lock ring is carved on each of the inner circumferential surface of one flange and the outer circumferential surface of the other flange, and an annular lock ring with a single cut is housed in the groove. The depth of the groove on one of the flanges is set to be greater than the height of the lock ring so that the lock ring can be accommodated in the groove in a submerged state, and the depth of only the other flange is set to be greater than the height of the lock ring. A door for a hyperbaric oxygen treatment device, characterized in that the door has a depth smaller than the height of the door, and is provided with means for arbitrarily applying an external force to force both ends of opposing lock rings to approach and/or expand by sandwiching the incision. locking device.
