Title:
LIQUID SAMPLING APPARATUS
Document Type and Number:
Japanese Patent JPS59160467
Kind Code:
A
Abstract:
A liquid sampling device (10), in particular intended for arterial blood sampling and blood gas analysis, is disclosed. The sampling device is provided with valve means (20, 21, 22) which in the dry state permits expulsion of gas from the sampler reservoir (18), but which automatically closes on contact with blood. The valve means comprises cooperating valve surface parts (21, 26) retained apart by a dry gas permeable material (22), which collapses on contact with a liquid, thereby moving the valve means to their closed position.
