INHALATION THERAPY DEVICE FOR USE IN PREMATURE BABIES AND INFANTS

摘要

For use in premature babies and infants, in particular for administering surfactant to the lungs, the inhalation therapy device described herein comprises an aerosol generating device 1, a respiratory air flow generating means 3 and a nebulising chamber 5 into which the generated liquid droplets 2 and the respiratory air flow 4 are supplied. The nebulising chamber 5 comprises a tapering area 52 which ends in a tubular intubation means 6. The intubation means 6 is designed such that the intubation end 6b can be positioned in such a manner that the liquid droplet/respiratory air mixture conveyed via the intubation means is released behind those areas of the respiratory tract that filter out to a great extent the liquid droplets from the mixture.

主权项

1. Inhalation therapy device comprising:
an aerosol generating device having a membrane and a piezo-oscillator that causes the membrane to oscillate for nebulising a fluid and providing liquid droplets; a nebulising chamber having a respiratory air supply opening to which a respiratory air flow is to be supplied and an area comprising a connecting piece to discharge a liquid droplet/respiratory air mixture formed by supplying liquid droplets and the respiratory air flow to the nebulising chamber, wherein the inhalation therapy device is configured to alternately switch the aerosol generating device on/off by means of an activation signal to the piezo-oscillator and to adjust the on/off switching phases, whereby the output rate of the aerosol generating device is adjustable.
