Patent number: 8221703Abstract: Disclosed herein is a device for collecting a sample, which is intended to dispense a received sample onto a measurement strip. The device includes a main body and a pair of receiving pieces. The receiving pieces protrude from a first end of the main body in such a way as to be spaced apart from each other while facing each other, and receive the sample by capillary force acting on a space which is defined between the receiving pieces and which is open on right, left and bottom sides. The device allows the received sample to be easily transferred to a reaction zone of a measurement strip, and enables the sample to be completely absorbed by the reaction zone because of capillary force in a receiving area when the device comes into contact with the reaction zone of the strip.Type: GrantFiled: March 11, 2010Date of Patent: July 17, 2012Assignee: Infopia Co., Ltd.Inventors: Byeong-Woo Bae, Sung-Dong Lee, Byung-Hoon Kho, Ji-Eon Ryu, Jin-Kyeong Kim, Hyou-Arm Joung, Ku-Cheol Ahn
