Abstract
A device for supplying a patient with breathing gas, which has a housing provided with gas ducts and a corresponding cover (5), shall be improved such that the cover (5) can be manufactured in a simple manner and possesses good sealing properties. To accomplish the object, provisions are made for the cover (5) to consist of a one-piece, plate-like elastomer material and for groove-like depressions (10) extending in the direction of partitions (6) to be present as a seal for the gas ducts (8).
Claims20
A device for supplying a user with breathing gas, the device comprising:
- a housing;
- a plate-shaped elastomeric cover formed from one piece of elastomer material, said cover covering said housing, said cover having a plurality of groove-like depressions;
- a plurality of partitions defining gas ducts in said housing, each partition having a front surface, said groove-like depressions of said cover sealing said gas ducts, said cover having a reduced elastomer material thickness in an area of said groove-like depressions, each groove-like depression extending along one of said partitions such that a portion of said front surface of each partition is located within one of said groove-like depressions.
A device for supplying a user with breathing gas, the device comprising:
- a respirator housing;
- a plurality of partition structures defining gas ducts within said respirator housing, each partition structure having a partition wall with an outer respirator housing cover contact surface, said partition wall defining a partition structure contour;
- an elastic respirator housing cover formed from a unitary piece of elastomer material, said respirator housing cover having a plurality of partition covering sections defining a plurality of partition receiving grooves, each partition receiving groove having a partition receiving groove contour corresponding to said partition structure contour of one of said partition structures, each partition receiving groove having an elastomer material thickness that is less than an elastomer material thickness of one of said partition covering sections, said respirator housing cover engaging said respirator housing such that each partition receiving groove receives said partition wall of one of said partition structures, each partition covering section engaging said outer respirator housing cover contact surface of one of said partition structures to seal said partition structure, whereby said respirator housing cover seals said respirator housing.
A device for supplying a user with breathing gas, the device comprising:
- a respirator device having a respirator housing with an outer housing surface;
- a plurality of partition walls defining gas ducts within said respirator housing, each partition wall having an outer contact surface;
- a respirator housing cover formed from an integral piece of elastomer material having an outer wall with an inner housing contact surface, said respirator housing cover having a plurality of elevated partition covering sections defining a plurality of partition wall receiving recesses, each partition wall receiving recess following a contour of one of said partition walls, each partition wall receiving recess having an elastomer material thickness that is less than an elastomer material thickness of one of said elevated partition covering sections, said inner housing contact surface engaging said outer housing surface such that each partition wall receiving recess receives one of said partition walls and each partition covering section engages said outer contact surface of one of said partition walls, whereby said respirator housing cover seals said respirator housing.
