Abstract

The invention discloses a hemoglobin determining method for donate blood, including plastic shell and test paper tape. The plastic shell contains light source, photoelectric sensor, test paper tape jack, photoelectric signal converting circuit, electric signal processing circuit, digital display circuit, power supply, switch, and display screen. Drip the blood on the test paper tape, turn on the switch, insert the test paper tape in the jack, make the light emitted from the light source transmit the test paper tape with blood to the photoelectric sensor and then pass through the photoelectric signal converting circuit, electric signal processing circuit and digital display circuit, so as to directly display the tested result on the display screen. It has small and exquisite bulk, convenient to carry and fast and reliable.

Description

technical field [0001] The invention relates to a voluntary blood donation hemoglobin measuring instrument capable of testing the hemoglobin content in human blood, especially a voluntary blood donation hemoglobin measuring instrument capable of judging whether there is anemia. Background technique [0002] The determination of hemoglobin content is widely used today, such as screening blood donors for anemia, antenatal examination and child health planning and disease management. At present, people's methods for detecting the content of hemoglobin in human blood are limited to the use of large-scale instruments and equipment, which inevitably has many disadvantages, such as inconvenient carrying, long time to calculate the results, and professional training for the use and maintenance of the instrument. , Use outside the hospital must rely on fixed power supply, etc. Contents of the invention [0003] The purpose of the present invention is to provide an automatic volunt...
