| abstract | 1283055 Apparatus for sampling and analysing breath MINE SAFETY APPLIANCES CO 28 Aug 1969 [4 Nov 1968] 42942/69 Heading A5R [Also in Divisions F2 and G1] A breath-sampling apparatus comprises a first conduit 2, one end forming a mouth-piece 4, the other end opening into a non-elastic inflatable bag 8, and having a branch tube 10, with an integral non-return valve which connects through a flexible tube 12 to a second non-elastic inflatable bag 16. The valve comprises a seat 18 integral with the branch 10 and a valve head 20 attached to a resilient block 22, of foamed rubber or foamed polyurethane which is compressed by a retaining ring 24. Air is exhaled into the mouthpiece and flows into and inflates bag 8. At a predetermined pressure, from 3 to 15 inches of water, the valve in tube 10 opens and air flows into bag 16. When the bag 16 is full, it is closed off by means of a clip across the connecting tube 12. The alcohol content of the air in the bag is measured by a colorimetric indicator which is contained within a breakable ampoule (34) within the bag 16 or a glass tube (28) which is connected to the bag 16 by the connecting tube 12 in place of the conduits 2, 10. |
