BI-LUMEN BREATHING CIRCUIT ASSEMBLY

摘要

A double-lumen breathing circuit assembly with separate breathing circuit conduit lengths can be joined together by differently arranged connectors or adapters. The connectors may each have different shapes and associated accessories that serve different functions. The breathing circuit conduit lengths may have an inner septum that extends both diametrically and axially for segregating inspiratory and expiratory lumens. Each septum may terminate at opposite distal ends of the conduit lengths and form a pair of semi-circular lumen openings. One of the bi-lumen breathing circuits may be connected to a patient-side connector, and the other bi-lumen breathing circuit may be connected to, or integrally moulded with, a gas collection plug of an anaesthetic gas machine. The latter bi-lumen breathing circuit may also be further connected to, or integrally moulded with, a carbon dioxide sampling connector, a temperature probe, and/or a pressure sensor probe.

主权项

1. A bi-lumen breathing circuit assembly including a first breathing circuit conduit length and a second breathing circuit conduit length, each comprising:
(i) a lengthwise extending inner septum for segregating an inspiratory lumen and an expiratory lumen; and (ii) lumen opening pairs at opposite distal conduit ends;the bi-lumen breathing circuit assembly further comprising a connector comprising:
(iii) a lengthwise extending connector septum for segregating an inspiratory connector passage and an expiratory connector passage; and (iv) a pair of connector openings at opposite distal connector ends;wherein a concavity is provided at each distal connector ends for sealingly receiving an inner septum of each breathing circuit conduit length thus ensuring a contiguous passage between connected lengths of breathing circuit conduits.
