Abstract

The invention relates to an equine inhalation mask, comprising at least one valveless combined inhalation and exhalation conduit, into which inhalant sources comprising respiration control elements and an energy supply that does not require supply lines are interchangeably integrated. A filter system is mounted on the outer end of the inhalation and exhalation conduit facing away from the head of the horse. Said system and the fact that the mask is effectively sealed when on the head of the horse prevent any escape of the aerosol into the environment, thus permitting a reliable inhalation therapy lasting several minutes under normal respiratory conditions.

Claims

1-11. -11. (Cancelled)

12. An equine inhalation mask sized and shaped for application to the nose portion of a horse'"'"'s head, including fastening means for releasable fixation to a horse halter thereon, and including a support for an inhalant source flow-connected to at least one conduit, the mask comprising a housing of oval tapering cross section with a sealing ring at its upper end,

wherein the at least one conduit is mounted at nostril level and is flow-connected with the mask interior for both inhalation and exhalation,

wherein the housing is of flexible yet rigid material, the housing being generally conical with a larger base-side being open and a smaller base-side being closed,

wherein the larger base-side includes a roughened inside portion and a sealing hose for applying an end of the upper mask to the horse'"'"'s head,

wherein a distribution conduit surrounds a front end of the mask that includes lateral breathing ports and

wherein the support is designed to exchangeably receive the inhalant source which is provided with respiration control elements.

13. The equine inhalation mask according to claim 12, wherein the roughened inside portion extends over at least 10 cm from an edge of the larger base-side.

14. The equine inhalation mask according to claim 12, wherein the at least one conduit is a combined inlet/outlet conduit.

15. The equine inhalation mask according to claim 12, wherein a filter is attached to an opening at an outer end of the at least one conduit facing away from the horse'"'"'s head.

16. The equine inhalation mask according to claim 12, wherein an exchangeable filter is held in a filter retainer of the at least one conduit, the filter being interposed between an expansion means and a tapering means.

17. The equine inhalation mask according to claim 15, wherein the filter is removably attached to the wall of the at least one conduit so as to cover the entire free opening thereof.

18. The equine inhalation mask according to claim 15, wherein the filter is adapted for filtration of exhaled air, consisting of

glass-fiber ceramic for mechanic filtration or

of polypropylene for electrostatic filtration or

of a physico-chemical filter material such as activated carbon.

19. The equine inhalation mask according to claim 12, wherein the sealing ring is made of a foamed material having an airtight cleanable coating and is roughened at an outer portion of its surface.

20. The equine inhalation mask according to claim 12, wherein the sealing ring is a soft hose of which at least one quarter is filled with a gel-like resilient substance.

21. The equine inhalation mask according to claim 12, wherein the sealing hose is made of an airtight rubber-like material and is open on both sides.

22. The equine inhalation mask according to claim 21, wherein one edge of the sealing hose includes at least two metal-reinforced openings for insertion of mask fasteners.

23. The equine inhalation mask according to claim 21, wherein one end of the sealing hose is attached to the larger base-side of the mask.

24. The equine inhalation mask according to claim 12, wherein mask fasteners are firmly attached to an outer surface of the mask at a maximum distance of 20 cm from an edge of the larger base-side.

25. The equine inhalation mask according to claim 12, wherein mask fasteners are designed as curved hooks opening donwardly towards the smaller base-side.

26. The equine inhalation mask according to claim 25, wherein the mask fasteners are oppositely situated in the region between the horse'"'"'s nose and lower jaw.

27. The equine inhalation mask according to claim 12, wherein a saliva collecting and evacuating means of easily cleanable material is detachably fixed to the mask by way of a bulge arranged at the smaller base-side in front of the horse'"'"'s mouth.

28. The equine inhalation mask according to claim 15, wherein the saliva collecting and evacuating means is transparent plastic for level control.

29. The equine inhalation mask according to claim 12, wherein the at least one conduit and the distribution conduit have free-flow cross sections of at least 4 cm at any location up to the breathing ports.

30. The equine inhalation mask according to claim 12, wherein the distribution conduit includes symmetric branches terminating opposite the horse'"'"'s nostrils.

31. The equine inhalation mask according to claim 12, wherein the inhalant source support is mounted to the housing.

32. The equine inhalation mask according to claim 16, wherein the filter is removably attached to the wall of the at least one conduit so as to cover the entire free opening thereof.

33. The equine inhalation mask according to claim 16, wherein the filter is adapted for filtration of exhaled air, consisting of

glass-fiber ceramic for mechanic filtration or

of polypropylene for electrostatic filtration or

of a physico-chemical filter material such as activated carbon.

34. The equine inhalation mask according to claim 17, wherein the filter is adapted for filtration of exhaled air, consisting of

glass-fiber ceramic for mechanic filtration or

of polypropylene for electrostatic filtration or

of a physico-chemical filter material such as activated carbon.

35. The equine inhalation mask according to claim 32, wherein the filter (5a) is adapted for filtration of exhaled air, consisting of

glass-fiber ceramic for mechanic filtration or

of polypropylene for electrostatic filtration or of a physico-chemical filter material such as activated carbon.
