Abstract

A sound dampening housing for conventional respiratory assist devices fabricated of pliant synthetic materials that provide good wear life and cleanability, and provide excellent sound dampening properties. The sound dampening housing substantially encloses a conventional respiratory assist device, but has openings or openable sections which positionally correspond to the functional elements of the respiratory assist device, e.g., air hose connections, blower or pump intakes, control interfaces, power connectors, etc.

Claims

1. A sound dampening enclosure for a respiratory assist device, comprising a plurality of panel members, each fabricated from a pliant material having sound dampening properties, each of the plurality of panel members being joined together to form an enclosure having a three-dimensional geometry, and at least one opening in the sound dampening enclosure defining a passageway for a functional element of the respiratory assist device.

2. The sound dampening enclosure according to claim 1, wherein the plurality of panel members are each fabricated of a plastic film laminated to a foam material.

3. The sound dampening enclosure according to claim 2, wherein the plastic film is selected from the group of vinyl and polyethylene.

4. The sound dampening enclosure according to claim 2, wherein the plastic film further comprises an perforated vinyl film.

5. The sound dampening enclosure according to claim 2, wherein the foam material is selected from the group of open-cell and closed-cell foam materials.

6. The sound dampening enclosure according to claim 2, wherein the plastic film component of the plastic film-foam laminate material forms all exterior surfaces of the sound dampening enclosure.

7. The sound dampening enclosure according to claim 5, wherein the plastic film is a vinyl film and the foam material is a closed-cell foam material, wherein the vinyl film forms all exterior surfaces of the sound dampening enclosure and the closed-cell foam material forms substantially all inner surfaces of the sound dampening enclosure.

8. The sound dampening enclosure according to claim 1, wherein the three-dimensional geometry further comprises a polyhedron.

9. The sound dampening enclosure according to claim 8, wherein the polyhedron further comprises a hexahedron.

10. The sound dampening enclosure according to claim 8, wherein the polyhedron defines a plurality of planar surfaces of the sound dampening enclosure formed by planar members defining at least a top surface, a bottom surface, a first side surface, a second side surface, a frontal surface and a rear surface.

11. The sound dampening enclosure according to claim 10, wherein the at least one opening passes through at least one of the plurality of planar surfaces of the polyhedron.

12. The sound dampening enclosure according to claim 1, wherein the at least one opening is formed by non-joined portions of the plurality of planar members.

13. The sound dampening enclosure according to claim 10, wherein the rear surface has at least one opening passing there through that accommodates an air outlet of a respiratory assist device.

14. The sound dampening enclosure according to claim 13, further comprising a frontal surface opening defined by non-joined ends of the planar members first side surface and the second side surface which are continuous with the frontal surface and by frontal edges of each of the top surface and the bottom surface.

15. The sound dampening enclosure according to claim 14, wherein the frontal surface opening is positioned and dimensioned to accommodate access to at least one of an air intake, an electronic control panel and an electrical power connector.

17. The sound dampening enclosure according to claim 16, wherein the foam component of the foam and vinyl film laminate material is selected from the group consisting of open cell foam and closed cell foam.

18. The sound dampening enclosure according to claim 16, wherein the vinyl film further comprises a perforated vinyl film.

19. The sound dampening enclosure according to claim 16 wherein each of the plurality of panel members are joined by seam stitching at abutting edges thereof.

20. The sound dampening enclosure according to claim 16, wherein the polyhedral enclosure comprising at least a top surface, a bottom surface, a first side surface, a second side surface, a frontal surface and a rear surface.

16. A sound dampening enclosure for a respiratory assist device, comprising a plurality panel members fabricated from a foam and vinyl film laminate material, each of the plurality of panel members being joined together to form a polyhedral enclosure having a plurality of outer surfaces and defining an interior chamber for receiving the respiratory assist therein, at least on of the plurality of outer surfaces having at least one opening permitting access to at least one functional element of the respiratory assist device.
