| 摘要 |
This invention is a heat, and moisture exchanger (960) including a gas permeable element (962) made of a fibrous media which traps the heat, the moisture from a patient's exhalant; which imparts heat, moisture to inspiratory gases as the patient inhales, conserving the patient's pulmonary heart and moisture. The media is made of a hydrophilic nylon polymer. The gas permeable element (962) can be formed entirely of mono-component fibers of the hydrophilic polymer or they may be a bi-component fiber having a sheath of the hydrophilic polymer with a thermoplastic core, e.g. polypropylene. The fibers are held together at their mutual points of contact with a bonding agent, e.g. polyester. |
