Cuffed medical tubes

摘要

A cuffed silicone tracheostomy tube has two tapered recesses on its outer surface in which opposite ends of a resilient cuff are bonded using an adhesive or solvent. Two shallow ribs extend around the tube on the inner edge of each recess, projecting outwardly to prevent the adhesive or solvent spreading onto the inflatable portion of the cuff. The cuff has several shallow ribs extending around the cuff and spaced along its inflatable portion to promote even inflation.

主权项

1. A cuffed medical tube having a tubular shaft and an inflatable sealing cuff extending coaxially along a part of the shaft and attached with the shaft at opposite ends, the cuff being of a resilient material and is substantially cylindrical to closely embrace the shaft along its entire length when deflated, characterized in that the cuff has a plurality of annular ribs spaced from one another along the length of the cuff on the inner surface of its inflatable portion and adapted to promote even inflation of the cuff to effect an inflated substantially cylindrical cuff, wherein the outer surface of the cuff does not have the annular ribs.
