Substance delivery arrangement for gas therapy device

Abstract

A mount provides a structure that facilitates coupling of a nebuliser downstream of a humidifier chamber and upstream of a conduit that delivers conditioned breathing gases to a patient or user. The mount can couple together a chamber, a nebulizer and a conduit.

         7 . A respiratory therapy system comprising:
 a flow generator adapted to deliver gases to a patient;   a patient interface;   a gas passageway extending between the flow generator and the patient interface; and   a nebuliser adapted to deliver a substance to at least a first portion of the gas passageway, at least a section of the gas passageway at and/or downstream of the first portion comprising a smooth bore conduit.   
     
     
         8 . The respiratory therapy system of  claim 7 , wherein a gas humidifier is present at a point along the gas passageway. 
     
     
         9 . The respiratory therapy system of  claim 8 , wherein the first portion is downstream of the gas humidifier. 
     
     
         10 . The respiratory therapy system of  claim 9 , wherein the smooth bore conduit comprises a conduit heater. 
     
     
         11 . The respiratory therapy system of  claim 10 , wherein the conduit heater is located substantially outside of a flow path of gases passing through the smooth bore conduit. 
     
     
         12 .- 32 . (canceled) 
     
     
         33 . The respiratory therapy system of  claim 11 , wherein the smooth bore conduit comprises a bead and a bubble that combine to define a smooth bore with minimal surface deviations. 
     
     
         34 . The respiratory therapy system of  claim 33 , wherein the bead comprises at least one resistive wire. 
     
     
         35 . The respiratory therapy system of  claim 33 , wherein the smooth bore of the smooth bore conduit has an internal diameter of 13-14 mm. 
     
     
         36 . The respiratory therapy system of  claim 33 , wherein the smooth bore of the smooth bore conduit has a surface roughness of 0.15-0.25 mm. 
     
     
         37 . The respiratory therapy system of  claim 7 , wherein at least a portion of the gas passageway downstream of the first portion of the gas passageway comprises a breathable wall to transmit vapour through the breathable wall. 
     
     
         38 . The respiratory therapy system of  claim 7 , wherein the patient interface comprises a full face mask, a nasal cannula, or an endotracheal tube. 
     
     
         39 . The respiratory therapy system of  claim 7 , wherein the flow generator is controlled based on operation of the nebuliser. 
     
     
         40 . The respiratory therapy system of  claim 39 , wherein a flow rate from the flow generator is reduced prior to release of a substance from the nebuliser into the gas passageway. 
     
     
         41 . The respiratory therapy system of  claim 8  further comprising at least one sensor that detects at least one characteristic of gases delivered to the patient and/or at least one health characteristic of the patient. 
     
     
         42 . The respiratory therapy system of  claim 41 , wherein the at least one sensor is downstream of the gas humidifier. 
     
     
         43 . The respiratory therapy system of  claim 7  further comprising a mount that connects the nebuliser and a portion of the gas passageway. 
     
     
         44 . The respiratory therapy system of  claim 43 , wherein the mount comprises a first duct with at least one portion extending vertically and at least one portion extending horizontally. 
     
     
         45 . The respiratory therapy system of  claim 44 , wherein the mount comprises an inlet port configured to receive the nebuliser. 
     
     
         46 . The respiratory therapy system of  claim 45 , wherein the mount connects to the gas humidifier. 
     
     
         47 . The respiratory therapy system of  claim 44 , wherein the mount comprises a second duct and, at a first portion, the first duct and the second duct are separated by a first distance and, at a second portion, the first duct and the second duct are separated by a second distance.
