RESPIRATION GYMNASTIC APPARATUS.

Application tiled March 16, 1927, Serial No. 175,905, and in Belgium March 18, 1926.

My invention relates to a respiration gymnastic apparatus which hasfor its object to increase the respiratory amplitude by a training, the progresses of whichmay be easily controlled. Apparatuses and processes of this kind hithertoknown donot allow the patient to watchthe progresses of his train ing; these progresses taking place unknown to the patient, and the want of control precluding the necessary emulation; the consequence is, generally, a want of perseverance and also the loss of benefit of the training.

In order to avoid the disadvantages of these apparatuses it has been suggested to make use of apparatuses in which the, displacement of a level of water indicates by difference the quantity of air which-has been blown in. In these apparatuses, the inspiration following the expiration has the. same amplitude and is gradually increasing, the lung adapting itself very quickly to the more active working which is required from it. In other known apparatuses, use is made of the displacement of air, but these apparatuses are, in reality, spirometers and not training apparatuses. Allthese apparatuses present great disadvantages: those in which use is made of a displacement of water, have a great resistance which is considered by the physiologists as excessive and also dangerous. Moreover, their handlingis less easy and requires the intervention of a third per.- son. Further, none of the known apparatuses can work with the speed of the respiratory rhythm although now the condition of the training is the judicious control of the repetition of the effort.

My apparatus has for its object to avoid these disadvantages to do away with all excess of resistance and to obtain continuity in the working, and is characterized by this fact that during inspiration an instantaneous manoeuvre, which can be carried out by the patient, the apparatus is ready forthe following blowing in. I

With this object in view my invention essentially consists in a special arrangement tient inhale.

1 is a transparent cylinder. for instance in.

glass in which acircular plate 2 is disposed this plate having a diameter equal to that into two chambers 5 and 6. The two chambers 5 and 6 are connected each to .a pipe, the

chamber 5 to a pipe 7 and the chamber 6 to a pipe '8, These two pipes 7 and 8 are connected to a common pipe 9 through a cook 10 movable by hand and provided with an outlet 11 opening in the atmosphere. p

The plate 2 may be providedwith a stop 12 of variable length according to thepoint of the cylinder 1, where the pipe 8 is connected, with respect to the extremities of the said cylinder 1 so as to avoid the blocking of the apparatus. j f I The working of the apparatus is the following: the deficiency in the respiratory capacity of the patient having been ascertained by means of a 'spirometer, the number of expirations and the volume of air which will be blown in at each expiration will be fixed.

The patient will afterwards blow into the -pipe 9 and the air which is breathed out will pass through the cook 10 into one of the chambers of the apparatus (in the example shown into the chamber 5) and will act upon the plate 2 which will be displaced along the graduation 4 and which will'cause a flowing 7 back of the air contained in the chamber. 6 through the pipe 8. The expiration will be stopped when the plate 2 will have reached the'graduation corresponding to the quantity of air which has been fixed. At this moment the greater the volume of air which has been expelled, the more deeply will then the pachamber 6*and will bring again the plate2 But at this moment also he to the graduation point Zero. In both cases 1 the air, which is in the chamberopposite to that into which the patient blows, will not be compressed and will be acted upon by the plate 2, will be conducted by one of the pipes 7 or 8, and will be finally expelled through v the outlet 11.

It will be easily understood that the cock 10 easy or tiring 'miifioeuvremnd this within the. limits prescribed by the doctors. (3) The resistance ofthe apparatus is ve slight and cannot be in anyway a cause of atigne to the patient.

n ,(4) The patient may follow de visuthe progresses offrhistraining.

He does net need anyhelp in order to manenvre the apperatus.
