A sealing and retaining arrangement for a humidifier with separable top and bottom members and an attaching arrangement for rigidly connecting a ventilator or other respiratory device to the top of the humidifier in a predetermined, fixed position. The sealing and retaining arrangement is designed for use between separable top and bottom members of a humidifier. The top and bottom are made of relatively rigid material and have overlapping or telescoping portions with a flexible, resilient seal extending therebetween. The seal also serves to positively retain the top and bottom together while in use. The attaching arrangement is designed to rigidly connect the ventilator or other respiratory device to the top of the humidifier in a predetermined, fixed position. This is accomplished by rigidly coupling the air outlet of the ventilator directly to the air inlet of the humidifier without any intervening, flexible hose.

A sealing arrangement primarily intended for use in a humidifier for a ventilator, said humidifier having separable, relatively rigid, top and bottom members, said relatively rigid, bottom member being a reservoir for holding water and having a bottom wall and a side wall, said side wall extending upwardly from and about said bottom wall to form therewith said reservoir for holding water, said side wall having an upper portion spaced from the bottom wall and extending about an axis, said separable, relatively rigid, top member of said humidifier being a cover for said bottom reservoir member and having a top wall and a side wall, said side wall extending downwardly from and about said top wall, said side wall of said top cover member having a lower portion spaced from the top wall and extending about said axis, one of said bottom reservoir member and said top cover member further including a resilient, flexible seal, said seal having a first section attached to one of the upper portion of the side wall of the bottom reservoir member and the lower portion of the side wall of the top cover member and extending about said axis, said seal further having a second section extending from the one of the upper portion of the bottom reservoir member and the lower portion of the top cover member to form a protruding lip, said upper portion of the side wall of the bottom reservoir member and said lower portion of the side wall of the top cover member being substantially concentrically shaped and dimensioned wherein said top cover member can be manually moved by a patient along said axis to a first, telescoping position relative to the bottom reservoir member with the respective upper and lower portions of the top cover member and bottom reservoir member overlapping and concentrically spaced a first distance from each other, said second section of said resilient, flexible seal forming said protruding lip having a relaxed state extending from the one of said upper and lower portions for a distance greater than said first distance said upper and lower portions are concentrically spaced from each other wherein said lip contacts and wipes along the other of said upper and lower portions in the direction of said axis as said top cover member is moved by the patient to said first, telescoping position relative to said bottom reservoir member, said lip on the one of said upper and lower portions sealingly engaging the other of said upper and lower portions in said first, telescoping position, and said sealing arrangement further including means for creating a signal to the patient indicating the top cover member has been moved to said first, telescoping and sealing position, said signal creating means including said lip and means for causing said lip to resiliently snap against the other of said upper and lower portions to create said signal when the top cover member has been moved to said first, telescoping and sealing position.
