Definitions
- This invention relates to a breathing method and apparatus
- this invention relates to a portable altitude simulator method and apparatus.
- the user employing the breathing method and apparatus can inspire air having a lower partial pressure of oxygen than the ambient air so as to simulate an altitude which is elevated with respect to where the method and apparatus is being employed.
- a user can become acclimatised to higher altitude before travelling to a place of higher altitude or for performance training or sporting activities or medical applications .
- Apparatus to generate a lower partial pressure of oxygen than ambient air, and thereby simulate altitude are known, e.g. US4086923.
- such devices are generally complex, including valve arrangements etc.
- a breathing apparatus including a container, mouthpiece means opening into the container, carbon dioxide removal means disposed in an air flow between the mouthpiece means and an air reservoir means, means for coupling the reservoir means to ambient air and means to adjust the effective volume of the air reservoir means whereby air from a user can flow through the removal means into the reservoir means for expirated air and ambient air to mix in the container such mixture to be inspired by the user through said mouthpiece means via said removal means.
- a method of breathing including the steps of expirating air through carbon dioxide removal means into a reservoir means of adjustable effective volume, supplying ambient air to said reservoir means, and inspiring air from said reservoir means through said carbon dioxide removal means.
- a breathing apparatus including a chamber, foam material in the chamber, a mouthpiece means, a carbon dioxide removal means disposed in an air flow between the mouthpiece means and the foam material, and inlet/exhaust port means.
- the inlet/exhaust port means is an opening into the chamber, the position of the opening being adjustable.
- the inlet/exhaust port means is a plurality of openings, there being closure means to selectively close all but one of the openings, the openings being spaced at different distances from the removal means.
- additional foam filled chambers may be coupled to the (first) chamber to increase the effective distance between the mouthpiece and the inlet/exhaust port means.
- the removal means is soda lime.
- the mouthpiece means is adjustable in position.
- the mouthpiece means is pivotally coupled to a cap which is removably mounted to an open end of the container.
- Figure 1 is a front elevation view of the apparatus
- Figure 2 is a top plan view of the apparatus
- Figure 3 is a sectioned cross-sectional elevation view of the apparatus
- Figure 4 is an exploded perspective view of a preferred embodiment of the apparatus
- Figure 5 is a sectional perspective view of the preferred embodiment .
- the apparatus 10 is a portable device which enables a user to conveniently breathe through the apparatus so as to simulate breathing at an altitude.
- the user is able to assimilate living at altitude and therefore become conditioned to the lower oxygen present at high altitudes.
- the portability of the apparatus enables the user to breathe through the apparatus during normal activity, however, any training activities would be conducted without use of the apparatus.
- the apparatus in a first form is in the form of an open-ended canister 11 with a removable top 12 mounted on the open end.
- This can be a screw-on cap though clearly other attachment means can be used such as clip-on, interference fit, etc.
- a mouthpiece 13 having an open or outlet end 13a is located within a recessed portion 14 of the top 12.
- the mouthpiece 13 is pivotally mounted by pivot 15. This enables the mouthpiece 13 to be moved from the rest position as shown in the drawings to an elevated position. In the elevated position a user can place his or her mouth over the outlet end 13a of the mouthpiece 13.
- a flexible hose or other conduit could be attached by any suitable means (including a simple push-on attachment) to the outlet end 13a of the mouthpiece 13.
- the other end of the hose would have a mouthpiece which could be engaged in or around the mouth and/or nose of the user.
- a mask or similar could be provided which could be held over the user' s mouth in any known manner such as, say, an elastic element which fits about the user's head.
- the mouthpiece 13 communicates via the passageway formed by breather tube 16 with a chamber formed by the interior of canister 11.
- the chamber is effectively divided into a first chamber part 17 and a second chamber part 19. This second chamber part 19, as will hereinafter become apparent, effectively acts as a reservoir for a mix of expirated air and ambient air.
- first chamber part 17 In the first chamber part 17 is located carbon dioxide scrub material 18. Chamber part 17 communicates via partition 28 with chamber part 19.
- the partition 28 preferably has a plurality of openings or passageways through which air can pass.
- the partition 28 can be formed by a foam material or a mesh. However, this partition 28 may in some arrangements not be required.
- the altitude to be simulated is adjustable. This is achieved by adjusting the effective volume of ambient air added to expirated air in second chamber part 19.
- This chamber part 19 effectively acts as a reservoir and mixing chamber in which ambient or new air can mix with expirated air.
- an inlet arrangement is provided in the wall of the canister 11 so that air can enter chamber 19 to mix with expirated air already within the chamber, the mixture of expirated and ambient air then being able to be drawn back through the carbon dioxi ⁇ e removal material 18 to ce breathed m by the user.
- the effective unit volume of air being supp_ ⁇ ed for inspiration by the user has a lesser oxygen content tnan the ambient air. This results m simulation of altitu ⁇ e above ambient .
- second chamber part 19 is fitted with foam material 27 to regulate airflow through the device.
- partition 28 can be omitted and the scrub material is simply supported by the foam material 27.
- adjustment means are provided whereby the simulated altitude can be ad usted.
- this can be achieved by adjusting the "altitude gauge" 22 (and therefore an associated mlet/exhaust port) up and down to different positions.
- the gauge 22 can be moved up and down to a desired position by an externally accessible operator button, knob or the like 21 which is slidingly engaged within an elongate longitudinally aligned slot 23.
- the air inlet/exhaust port (to enable air to exhaust from and ambient air to enter the mixing chamber 19) can be an opening which moves with the knob 21 such that it always communicates with the chamber 19 as different positions dependent on the position of the knob 21.
- a series of openings 24 could be provided in the wall of the canister 11. Each of these openings 24 would be closed by removable plug 25. The user would then remove the plug from the opening 24 adjacent the altitude marking indicating the altitude being simulated. Thus, for example, to simulate an altitude of 3000 metres the plug would be removed from the opening 24 adjacent the 3000 metre indicator.
- Figures 4 and 5 illustrate a further preferred embodiment of the invention wherein the same reference numerals have been used where possible.
- Figure 4 illustrates an exploded view wherein all foam inserts are denoted 27.
- the two chambers 17, 19 are m this embodiment, separate 'modules' that may be fitted together end- to-end, e.g. in an interference or click fit.
- Module 17 includes carbon dioxide removal means 18 as previously. Removal means 18 is readily accessible, due to the modular nature of the apparatus, and may be replaced or reconditioned as necessary.
- Module 19 includes (in the illustrated form) two foam filters 27 that restrict air flow through the apparatus from the intake 29 below.
- the effective volume is adjustable by adding or removing foam filters 27 or, preferably, fitting additional modules 19 (by interference fit at areas 30 and 30a) . Additional modules 19 will thereby make the whole apparatus 10 longer than illustrated. Increasing the number of modules 19 in series increases the simulated altitude as there is a greater distance (through the foam 27) between the mouthpiece 13 and the inlet/exhaust 29.
- the total volume of the canister could be up to 5000mL though more particularly between about 500 and 2000mL.
- the amount of carbon dioxide scrub material 18 could then be m the order of 100-500g when soda lime is used. Scrub materials other than soda lime could be ised.
- a smaller device could be provided with a smaller chamber 18 having a carbon dioxide absorbent material.
- the size of chamber 19 could also be reduced.
- the preferred product specification of foam is 23105.
- the density of this foam is 23kg/m 3 with a hardness factor of 105N.
- the apparatus in a less preferred form could include a balloon or bag that fills up with some of the expired air on expiration and then empties on inhalation. Such an arrangement could further reduce the size of the apparatus.
- the device could be ma ⁇ e disposable. If economical production costs can be realised the device could be used, say, four times and Lhen thrown away m the trash. However, the device would be reusable by replacing the carbon dioxide scrubber/absorber material 18 as required.
- the apparatus useable ancillary equipment can be provided.
- lid 12 with a built m time means 26.
- the user can set the timer 26 so that when it times out a visual or audible signal can be set off. This will enable the user to establish a time limit for ending use of the apparatus.
- a compact portable apparatus which can be used to simulate breathing at altitude is thus achievable by the present invention. This is acnieved by passing air expirated and mspirated by the user through the carbon dioxide scrubber/absorber material. Thus, air passes through the material on both inhalation and exhalation. This results in a compact device and indeed one which could be disposable in nature.
