Abstract

493,061. Blood-withdrawing devices. PHILIPSEN, M. March 30, 1937. No. 9069. [Class 81 (ii)] [Also in Group XX] A device for withdrawing a specimen of blood for testing in a haemoglobinometer has a capillary aperture a leading into a receptacle b which opens into a larger aperture c. Blood is caused to start flowing into the vessel by suction produced by movement of the thumb on the rim 16, and continues to flow under capillary action until the receptacle b is filled the flow then ceases.
