Claim 3

The respiratory control as claimed in claim 1 wherein said means defining said mouthpiece is provided with a safety shield outwardly of said first open end which engages the lips and area surrounding the mouth to prevent swallowing of the respiratory control.

Claim 4

The respiratory control as claimed in claim 2 further including teeth gripping means spaced from said safety shield.

Claim 5

The respiratory control as claimed in claim 3 wherein said means for dividing said cavity into corridors and said filter define a replaceable cartridge for the mouthpiece.

Claim 6

The respiratory control as claimed in claim 4 wherein said valve means comprises a ridge extending inwardly of said bore and transversely in each respective corridor which define shut-off valve lands for said valve means and relatively thin oppositely directed walls extending into each corridor from said cartridge towards said ridges, said walls being disposed with respect to said ridges thereby cooperating with said ridges to define a pair of one-way valves which operate in opposite directions during inhalation and exhalation.

Claim 7

The respiratory control as claimed in claim 4 wherein said valve means comprises a ridge extending inwardly of said bore and transversely in each respective corridor which define shut-off valve lands for said valve means and relatively thin oppositely directed walls mounted in said bore and extending into each corridor towards said ridges, said walls being disposed with respect to said ridges thereby cooperating with said ridges to define a pair of one-way valves which operate in opposite directions during inhalation and exhalation.

Claim 8

The respiratory control as claimed in claim 6 wherein said cartridge is provided with means for preventing movement of the filtering material.

Claim 9

The respiratory control as claimed in claim 7 wherein said means for preventing movement of said filtering material comprises spikes which interface with said filtering material.

Claim 10

The respiratory control as claimed in claim 8 wherein said means for preventing movement of said filtering material comprises posts on said cartridge for preventing movement of said filtering material towards the throat area.

Claim 11

The respiratory control as claimed in claim 9 wherein said cartridge has ribs extending the length thereof for spacing said cartridge in said bore and means associated with said bore for aiding in the insertion of the cartridge into the bore.

Claim 12

The respiratory control as claimed in claim 10 wherein said cartridge is provided with locking means which engage in cooperating locking means in said bore for locking said cartridge within the bore.

Claim 13

The respiratory control as claimed in claim 11 wherein said valve means is used to control the inhaled or exhaled pressure required to open said valve means into either corridor to exercise a person's lungs.

Claim 14

The respiratory control as claimed in claim 12 further and including additional filtering means in the exhaled corridor for trapping mucus and the like exhaled from a person.

Claim 15

A respiratory control comprising, envelope means defining a mouthpiece adapted to be inserted inside the mouth cavity and having a bore extending therethrough with first and second open ends, said bore being tapered from said first open end to said second open end, said first open end adapted to be located near the entrance to the mouth cavity and said second open end being adapted to be located in the back or throat portion of the mouth cavity; cartridge means for insertion in said air cavity to divide said bore into an air inhalation corridor for the flow of air into the person's throat and an exhalation corridor for the flow of air from the person's mouth; filtering means in said inhale corridor for filtering the air entering the mouth cavity; and valve means for preventing the exhale air flow from entering the inhale air corridor to maintain the filtering material clean of exhaled contaminated air and prevent inhaled air from passing through the exhale corridor and in combination keep the inhaled air controlled.

Claim 16

A respiratory control comprising, envelope means defining a mouthpiece adapted to be inserted inside the mouth cavity and having a bore extending therethrough with first and second open ends, said bore being tapered from said first open end to said second open end, said first open end adapted to be located near the entrance to the mouth cavity and said second open end being adapted to be located in the back or throat portion of the mouth cavity; cartridge means for insertion in said air cavity to divide said bore into an air inhalation corridor for the flow of air into the person's throat and an exhalation corridor for the flow of air from the person's mouth; filtering means in said inhale corridor for filtering the air entering the mouth cavity; and valve means for preventing the exhale air flow from entering the inhale air corridor to maintain the filtering material clean of exhaled contaminated air and prevent inhaled air from passing through the exhale corridor and in combination keep the inhaled air controlled.

Claim 17

A mouthpiece for respiratory control adapted to be used with a filtering means comprising, envelope means defining a mouthpiece adapted to be inserted inside the mouth cavity and having a bore extending therethrough with first and second open ends, said bore being tapered from said first open end to said second open end, said first open end adapted to be located near the entrance to the mouth cavity and said second open end being adapted to be located in the back or throat portion of the mouth cavity, filtering means in said bore defining means dividing said bore into an air inhalation corridor for the flow of air into the person's throat and an exhalation corridor for the flow of air from the person's mouth, said filtering means being located in said inhalation corridor, valve means for preventing the exhale air flow from entering the inhale air corridor to maintain the filtering material clean of exhaled contaminated air and prevent inhaled air from passing through the exhale corridor and in combination keep the inhaled air controlled, wall means extending outwardly from said first opening and generally perpendicular to said bore to define a safety means.

Claim 18

A mouthpiece for respiratory control adapted to be used with a filtering means comprising, envelope means defining a mouthpiece adapted to be inserted inside the mouth cavity and having a bore extending therethrough with first and second open ends, said bore being tapered from said first open end to said second open end, said first open end adapted to be located near the entrance to the mouth cavity and said second open end being adapted to be located in the back or throat portion of the mouth cavity, filtering means in said bore defining means dividing said bore into an air inhalation corridor for the flow of air into the person's throat and an exhalation corridor for the flow of air from the person's mouth, said filtering means being located in said inhalation corridor, valve means for preventing the exhale air flow from entering the inhale air corridor to maintain the filtering material clean of exhaled contaminated air and prevent inhaled air from passing through the exhale corridor and in combination keep the inhaled air controlled, wall means extending outwardly from said first opening and generally perpendicular to said bore to define a safety means.

Claim 19

The mouthpiece as claimed in claim 15 wherein said valve means includes a valve member connected to said filtering means and a valve seat mounted in said bore of said envelope means.

Claim 20

The mouthpiece as claimed in claim 15 wherein said valve means includes a valve member and a valve seat mounted in said bore of said envelope means.

Claim 21

The mouthpiece as claimed in claim 17 wherein said valve member is pivotally connected in said bore of said envelope means.
