Respirator machine humidifier with hollow fibre membrane

摘要

This respirator machine humidifier has an outer casing, water supply, respiration gas supply and offtake line. Humidification is carried out by a bundle of hydrophobic hollow fibres, which are permeable to water vapour, but not to liquid water. The gas supply and off take are connected by the interior of the hollow fibre strands. In the novel unit, there are means of electrical heating around the hollow fibres (7) and along the length of their outer circumferential surfaces. The hollow fibres are PTFE, polyurethane, polysulphone or porous glass sinter treated hydrophobically by a silicone.
