Patent number: 10571425Abstract: A disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance, but no additional air escape vent. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The sampling entrance provided can draw fluid into the chamber through any part of the opening, allowing easy targeting the samples with small volume, picking up smeared samples, and added tolerance to users who jam the tip of the sensor into users' finger. The sampling entrance also serves as air escape vent. Such one opening sensor alleviates over-flow issue often encountered in convenient sensors.Type: GrantFiled: February 12, 2019Date of Patent: February 25, 2020Assignee: Changsha Sinocare Inc.Inventors: Hongli Che, Shaobo Li

Patent number: 10527576Abstract: A disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance, but no additional air escape vent. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The extra wide sampling entrance provided by the present invention can draw blood into the chamber through any part of the opening, thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.Type: GrantFiled: August 23, 2018Date of Patent: January 7, 2020Assignee: Changsha Sinocare Inc.Inventors: Xiaohua Cai, Hongli Che, Shaobo Li

Patent number: 10386323Abstract: An improved disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The novel extra wide sampling entrance of the test sensor provided by the present invention can draw blood into the chamber not only from the front of the sampling entrance as usual in convenient sensors, but also from the top, bottom, left corner and right corner of the sampling entrance. Thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.Type: GrantFiled: February 26, 2018Date of Patent: August 20, 2019Assignee: Sinocare Inc.Inventors: Xiaohua Cai, Hongli Che, Shaobo Li

Publication number: 20190017956Abstract: The present invention relates to disposable test sensors having improved sample application and measuring properties and their uses for detection, preferably, quantitative measurement, of analyte in a liquid sample like blood. In particular, the invention provides for an electrochemical biosensor which has a thin-layer fluid chamber having funnel-like shape with a novel extra wide opening as sampling entrance and a vent opening at the tip of the chamber for air escape. The thin-layer fluid chamber provides a reservoir from which a sample fluid can be drawn into it through capillary action. The extra wide sampling entrance provided by the present invention can draw blood into the chamber through any part of the opening, thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.Type: ApplicationFiled: January 11, 2018Publication date: January 17, 2019Inventors: Xiaohua Cai, Hongli Che, Shaobo Li

Patent number: 10156538Abstract: The disclosure includes a control method for test strip electrodes. The method can include inserting a test strip into a glucose meter and applying a predetermined voltage to the working electrode W of the test strip. The Method can also include applying a sample to the test strip and acquiring real-time data of current generation at the electrodes R1 and R2 of the test strip. Some embodiments can also include determining whether the electrode R1 generates current earlier than the electrode R2 or not.Type: GrantFiled: April 21, 2015Date of Patent: December 18, 2018Assignee: SINOCARE INC.Inventors: Xiaohua Cai, Hongli Che, Yongsheng Dai, Zecun Huang, Wei Zhang
