The invention discloses a simple dry blood suction head quantitative blood sampling device which comprises a hydrophilic fiber material, a suction head, a pipettor and a suction head box. And the hydrophilic fiber material is loaded in the suction head and is 0.8-2.0 cm away from the liquid suction end of the suction head. The method further analyzes a dried blood tip sample, and verifies that the method has quantitative collection and analysis capabilities. The blood sampling device integrates online collection, storage, transportation and treatment, so that the risk of sample pollution is reduced, and the accuracy of the quantitative detection result of the dry blood suction head is improved; meanwhile, operation is easy and convenient, the patient can complete self-sampling and does not need to go to a hospital for blood sampling, and crowd gathering and infectious diseases can be reduced. 本发明公开了一种简易式干血吸头定量采血装置，包括：亲水纤维材料、吸头、移液器和吸头盒；所述亲水纤维材料负载于所述吸头内距吸头吸液端0.8～2.0cm。本发明进一步对干血吸头样品进行分析，验证本发明具有定量采集及分析的能力。本发明的采血装
