$69,523, I Patented June 7, 1910.



Specification of Letters Patent.

Patented June '7, 1910.

Application filed April 12, 1909. Serial No. 489,395.

T 0 all whom it may concern:

Be it known that I, HENRI Ennn, a citizen of the-French Republic, and resident of Paris, France, have invented certain new and useful Improvements in Inhalers, of which the following is a specification.

This invention relates to an apparatus intended to allow of the rapid curing of persons afiiicted with pulmonary diseases such as tuberculosis, by means of a medical powder which thanks to the apparatus may be aspirated in a finely divided state. This powder directly goes into the lungs and sticks on the parts attacked and thus realizes the cure of the latter in a relatively very short space of time.

The accompanying drawing given by way of example shows one form of embodiment of this invention and in this drawing, Figure 1 shows longitudinal axial section of the apparatus while Fig. 2 is a horizontal section of same on line AB of Fig. 1.

This apparatus is formed of a cylindrical receptacle made of any suitable material and preferably of metal. It is composed of two parts 1 and 2 which are unitedtogether in a detachable manner by means of a joint 3. The lower part 2 of this receptacle carries on its bottom a horizontal tube 4 which is curved along a semi-circle and has its escape openings 5 and 6 situated about diametrically opposite each other. In front of these escape openings 5 and 6, the wall of the tube is slightly extended and curved so as to form baffle plates 7 and 8. The tube 4 carries in its middle portion a tubular extension 9 which is secured in a tight manner into the wall of the part 2 through which it passes so as to end outside this part 2 by an olive shaped nozzle 9 intended to receive the end of the flexible tube 10 of a rubber ball allowing of the air being forced into the tube 4-. The upper part 1 of the receptacle is provided with an elongated opening 11 to which a similarly shaped extension 12 is connected which is directed obliquely upward and the extreme part of which is slightly widened so as to allow of the mouth of the patient being easily applied to the mouth of this tubular extension. Arranged across the opening 11 of the part 1 is a wire gauze 13 having rather large meshes.

The above described apparatus is employed in the following manner :-After having separated the two parts 1 and 2 of the apparatus, one introduces into the lower part 2 a suitable amount of medical powder. The apparatus is thereafter closed again and the patient applies his mouth against the tubular extension while forcing into the apparatus a violent air current by means of the india rubber ball. This air current escaping under pressure through the openings 5 and 6 of the tube 4 where it is more disturbed by the battle plates 7 and 8, causes the medical powder contained in the apparatus to be raised in a whirlwind so that the patient can inhale this powder in an extremely divided state. The medical powder is thus introduced into the lungs and is adapted to stick directly to the afliicted parts and to operate the rapid healing of the latter. The sieve has for its object to regularize the escape of the powder from the tubular extension 12.

Having now fully described my said invention what I claim and desire to secure by Letters Patent, is

1. In an apparatus of the class described, the combination with an elongated casing containing a finely divided substance in its lower portion and having an outlet in its upper portion, and an air tube extending into the lower portion of said casing, said tube having independent branches extending horizontally abreast of the bottom of the casing, said branches having discharge openings and curved lip portions at said openings for imparting a whirling movement to the discharging air.

2. In an apparatus of the class described, the combination with an elongated casing containing a finely divided substance in its lower portion and having an outlet in its upper portion, and an air inlet tube having two branches in said casing lying abreast of the bottom thereof and shaped to conform to and lying close to the wall of said casing and extending from one wall portion thereof to points opposite the vertical axis of said casing, the ends of said branches having discharge openings and the discharge openings having curved lip portions for imparting a whirling movement to the discharging air.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
