Plural Orifice Means Passing Gas Into Liquid Patents (Class 128/200.13)
  • Patent number: 11197965
    Abstract: The system allows optimizing the dispensing of aerosol medicaments. In particular the system allows the administration of an exogenous pulmonary surfactant to very young patients (e.g. preterm neonates). A catheter (101) conveys atomized surfactant directly to the retropharyngeal region in order to increase efficiency of the medicament administration without being invasive: this is particularly important for very young patients, such as pre-term born neonates suffering from neonatal Respiratory Distress Syndrome (nRDS). The catheter is made of biocompatible flexible material (e.g. plastic material). It is possible to couple the catheter with a rigid scaffolding (e.g. metallic) to increase stiffness of the device and to improve easiness of positioning operations. The delivery of the atomized medicament is done by means of an air blasting technique.

    Abstract: A flow generator includes a blower, a flow generator outlet configured to receive an end of a gas delivery tube, and a controller. The flow generator outlet includes electrical connectors configured to contact corresponding electrical connectors associated with the breathable gas delivery tube when the breathable gas delivery tube is received by the flow generator outlet. The controller includes a tube-type detect circuit and is configured to receive signals from the breathable gas delivery tube by way of the electrical connectors of the flow generator outlet. The tube-type detect circuit is configured so that when the breathable gas delivery tube is received by the flow generator outlet, the tube-type detect circuit determines the type of breathable gas delivery tube based on signals from the electrical connectors of the flow generator outlet that are indicative of a condition of a resistor associated with the breathable gas delivery tube.
