Abstract

1275687 Respiratory apparatus F M BIRD and H L POHNDORF 22 July 1970 [22 Aug 1969] 35482/70 Heading A5T [Also in Division F2] A device forming part of a respiratory apparatus comprises a venturi assembly 21 having a venturi passage 27 having at one end passages 31 open to the atmosphere and a jet nozzle 29 directed along passage 27 and adapted to be connected to a source of gas under pressure, a housing 23 having a flow passage 52 connected and aligned with passage 27, said housing having an exhalation port 53 which has a seat 56 adapted to receive a manually operated valve member 54 having a conical surface 57 which closes the exhalation port, and a mouthpiece 24 having a flow passage 78 in alignment with passage 27. A nebulizer 22 may be provided between the venturi assembly and housing 23, said nebulizer having a jet nozzle 42 adapted to have air blown therethrough to draw medication up capillary tube 41, the medication being broken into small drops by ball 43 and entrained in the main air flow entering housing 23. Valve member 54 is carried on a stem support member (66) Fig. 3, (not shown), which has a passage 68 which is closed by a conical surface 71 on valve member 54. Air is supplied to a tee 74 from which it is carried by pipes to nozzles 42 and 29. When port 53 and passage 68 are closed by conical surfaces 57 and 71 respectively air passes through nozzles 29 and 42 and a flow of medicated air is supplied for inhalation by the patient through mouthpiece 24. When valve member 54 is raised to open port 53 and passage 68 substantially all the air supplied to the device bleeds through said port along with air exhaled by the patient.
