Definitions
- This invention relates to respiratory muscle training devices.
- a respiratory muscle training device comprising a mouthpiece attached to a tubular body with a resistor sleeve coaxial with the body tube and having a number of resistance openings which align with a body tube opening and a selective one way flap exhaust valve which can be rotated 180 degrees to provide for inspiratory or expiratory training.
- the size of the resistance opening is not infinitely and continuously variable, fine adjustments to its size not being possible, whilst the process of selecting a particular resistance setting might be problematic for an elderly population with impaired dexterity.
- the invention provides a respiratory muscle training device comprising a mouthpiece connected to a tubular body portion, the body portion having an adjustable resistance opening whereby the opening may be obscured to a greater or lesser extent, an exhaust opening, communicating with the interior of the body portion, and a one way exhaust valve to open and close the communication through the exhaust opening.
- the exhaust valve is a ball valve contained in an adjustable housing whereby the distance the valve has to travel to seal off the exhaust opening during inhalation by a user of the mouthpiece is adjustable.
- the device comprises a one way exhaust valve, wherein the distance that the ball of the ball valve is required to travel in order to seal the exhaust aperture during inspiratory training is adjustable. It is also possible for said distance to be reduced to zero, such that the exhaust aperture is permanently though reversibly sealed, so allowing for expiratory training.
- a tubular sleeve is mounted to be movable on the body portion, the body portion having guide means to enable the position of the sleeve to move relative to the body portion whereby the resistance opening can be obscured to a greater or lesser extent by the sleeve, the degree of obscurement being continuously variable between the fully obscured and the not obscured positions of the sleeve.
- the guide means may consist of a screw thread arrangement between the tubular body portion and the sleeve whereby rotation of the sleeve or tubular body portion moves them linearly with respect to each other in the direction of the longitudinal axis of the body portion.
- the screw thread preferably extends on the outer surface of the tubular body containing the resistance opening.
- the device may be of generally T shape with the tubular body portion providing the cross-bar of the T' and the mouthpiece and its connection to the body portion providing the tail of the T.
- the resistance opening may be on one arm of the cross-bar of the T' and the exhaust valve on the other arm of the cross-bar of the T'.
- the means to obscure the resistance opening may be a threaded sleeve in the form of an end-cap on the arm of the cross-bar of the T.
- the device may be generally linear with the mouthpiece at one end, the exhaust valve at the other end and the resistance opening located between them.
- Figure 1 shows a plan view of one device of the invention from above, in the fully closed position
- Figure 2 shows the device of Figure 1 opened and ready for use
- Figure 3 shows in cross-section the device as depicted in Figure 1 ;
- Figure 4 is a similar view to Figure 2 of a second device of the invention.
- Figure 5 shows in cross-section the upper half of the device depicted in Figure 4 as viewed from below.
- the device 10 comprises a T-shaped tube arrangement, portion 11 of which serves as the mouthpiece through which the user breathes and tubular body portion 12 of which remains external to the mouth serving to control the flow of air through the device during inhalation and exhalation.
- the restriction placed on the flow of air through the device during inhalation is adjusted by means of the screwcap 13 on one end of body portion 12. Unscrewing the screwcap 13 reveals an aperture 14 through which air enters during inhalation; the more of the screwcap 13 is unscrewed the greater the effective size of the aperture 14. Increasing the effective size of the aperture 14 reduces the load on the inspiratory muscles during inhalation making inhalation easier whilst reducing the effective size of the aperture 14 increases the load making inhalation harder.
- the thread of the screwcap 13 is sufficiently fine so as to ensure that fine adjustments to the effective size of the aperture 14 are possible.
- the air leaves the device primarily through the apertures 15 which are of a fixed size and collectively much larger than the aperture 14 so ensuring that the user can exhale freely.
- the cross-section reveals the ball valve system which controls the flow of air through the apertures 15 during inhalation and exhalation.
- air is drawn through the mouthpiece 11 in the direction of the arrow 16, so decreasing the pressure in the chamber 17 inside the tubular body. Whilst this momentarily causes some air to be drawn through the apertures 15, air which is drawn in through a small hole 18, in an end-cap 22 threaded on to the opposite end of body portion 12 to cap 13, soon forces a lightweight plastic ball 19 placed inside end-cap 22 in the direction of the arrow 20.
- the exhaust aperture 21 defined by annular shoulder 21A in the body portion is thereby sealed.
- the exhaust aperture might also feature a rubber washer to improve the seal.
- This sealing effect ensures that the air entering the mouthpiece is subsequently limited to that passing through the aperture 14.
- the momentary delay in the action of the ball valve in sealing the exhaust aperture 21 allows the user, on commencing inhalation, to gain some momentum before the resistance is met, this providing for both a safer and more pleasant experience.
- the duration of this delay may be increased by unscrewing the screwcap 22: the more the screwcap 22 is unscrewed, the greater the distance the ball 19 has to travel in order to seal the exhaust aperture 21 and so the greater the delay experienced before the resistance is met.
- the pressure in the chamber 17 increases causing the ball 19 to return to its starting position as depicted in Figure 3 thereby allowing the air to escape freely through both the aperture 14 and the larger apertures 15.
- the device comprises a generally linear tubular body 30 having an end portion 31 being connected to a rubber mouthpiece (not shown) through which the user breathes and a portion 32 remaining external to the mouth and serving to control the flow of air through the device during inhalation and exhalation.
- the restriction placed on the flow of air through the device during inhalation is adjusted by means of a threaded sleeve 33 coaxial to the tubular body which, being engaged to and co-operable with a corresponding thread 34 on the surface of the tubular body, when rotated clockwise or anticlockwise, adjustably obstructs an aperture 35 cut into the tubular body through which air enters during inhalation.
- Increasing the effective size of the aperture 35 reduces the load on the inspiratory muscles during inhalation making inhalation easier whilst reducing the effective size of the aperture 35 increases the load making inhalation harder.
- the thread of the sleeve 33 is sufficiently fine to ensure that fine adjustments to the effective size of the aperture 35 are possible.
- the cross-section reveals the ball valve system which controls the flow of air through the aperture 36 during inhalation and exhalation.
- air is drawn through the mouthpiece 31 in the direction of the arrow 37, so decreasing the pressure in the chamber 38.
- the duration of the momentary delay in the action of the ball valve in sealing the exhaust aperture 42 which determines the degree of momentum achieved in the inhalation process before the resistance is met, may be increased by unscrewing the threaded screwcap 43 which is engaged to a corresponding thread 44 on the surface of portion 32: the more the screwcap 43 is unscrewed, the greater the distance the ball 40 has to travel in order to seal the exhaust aperture 42 and so the greater the delay experienced before the resistance is met.
- This ability to increase the delay is again important since it helps guard against the possibility of overstressing or 'jerking' the respiratory muscles at the commencement of inspiration.
- the device might just include the sleeve 33 and aperture 35 arrangement with the end of the tubular body being sealed in which case the user, during inspiratory training, would be required to exhale through their nose.
- the device may also be used for expiratory muscle training. To do so the cap 43 is rotated so as to cause the plastic ball 40 to seal the exhaust aperture. The user then breathes in through the nose and out through the device, the expiratory resistance being varied by adjustably obstructing the aperture 35 by rotating the sleeve 33 as described above.
- the device may be prescribed for persons with respiratory problems, or anybody wishing to develop the strength and endurance of their respiratory muscles e.g. singers, athletes, divers.
