Laryngeal mask airways and their manufacture |
摘要 |
A laryngeal mask assembly has a mask portion 13 of elliptical shape formed by a mount 15 and an inflatable member 16 attached to the mount. The inflatable member 16 is formed by heat bonding together opposite walls (31) and (32) of a flat balloon (30) and at the same time cutting an aperture 26 through the walls, so as to form a central web 25 within an outer inflatable ring 24. The central web 25 is attached to a concave surface 19 on the forward surface of the mount 15 with the aperture 26 in the web aligned with an opening 22 in the mount. |
