654,872. Respiratory appliances. ABBOTT LABORATORIES. Aug. 20, 1948, No. 13228/50. Convention dates, Sept. 4, 1947 and April 30, 1948. Divided out of 654,860. [Class 81 (ii)] A container for dispensing finely divided material has a foraminated end and an external flange with radially extending lugs, remote from the foraminated end, for supporting it in a holder with the foraminated end in the path of a stream of air flowing through the said holder. The invention is described in relation to a medical device for the inhalation of powder of the type described in Specification 654,860 in which a ball 42 is raised by the suction of the patient when he inhales through a mouthpiece 48. At the top of its movement the ball 42 strikes against a cylindrical container 12 which is loosely supported in the body by its flanged end 30, so that medicated powder 14 is sprinkled through a gauze screen 16 into the air stream. The container is provided with a handle 20 and its rim has diametrically placed projections forming a bayonet catch which prevents it inadvertently falling from the body. |
