Publication number: 20200155000Abstract: A fetal movement measuring device includes a detection unit and a smart device. The detection unit is selected from elastic materials and is attachable to an abdomen of a pregnant woman. The detection unit includes multiple branch sections extending outward therefrom. Each of the branch sections includes a fetal movement sensor and an electrode patch. The fetal movement sensor and the electrode patch are connected to a main circuit board to transmit an abdominal dynamic physiological signal detected by the fetal movement sensor and a fetal electrocardiographic signal detected by the electrode patch to the main circuit board. The smart device is operable to receive the abdominal dynamic physiological signal and the fetal electrocardiographic signal from the main circuit board and includes a fetal movement algorithm program that calculates and generates fetal movement data and the fetal heart rate.Type: ApplicationFiled: December 17, 2019Publication date: May 21, 2020Inventors: Yi Chun Du, Bee Yen Lim

Patent number: 10441293Abstract: A hemostatic method is performed as follows: A) An at-puncture hemostatic pressure is applied to a puncture in a blood vessel via a main geometric side, and at least one off-puncture hemostatic pressure is applied to at least one position away from the puncture via at least one auxiliary geometric side, wherein the off-puncture hemostatic pressure acts on the blood vessel either directly or indirectly. B) During the hemostatic process, an ongoing flow velocity of the blood in the blood vessel is obtained and is reduced to lower than a normal flow velocity in the blood vessel by applying the at-puncture and off-puncture hemostatic pressures simultaneously, wherein the at-puncture and off-puncture hemostatic pressures are lower than a systolic pressure in the blood vessel.Type: GrantFiled: January 9, 2017Date of Patent: October 15, 2019Assignee: Southern Taiwan University of Science and TechnologyInventors: Yi-Chun Du, Bee-Yen Lim, Shi-han Chen

Publication number: 20190271603Abstract: A woven article and a method for detecting a stress distribution of the woven article under stress are provided. The woven article includes a woven body and a plurality of metallic yarns connected to the woven body and spaced apart from each other. The woven body defines more than one direction thereon. The metallic yarns each extend in the direction. A resistance sensor is connected with each of the metallic yarns. A stress is exerted on the woven body, and the resistance sensor detects a resistance value generated by the metallic yarns on the woven body. According to the resistance value detected by the resistance sensor, a stress distribution of the woven body under stress can be obtained.Type: ApplicationFiled: March 5, 2018Publication date: September 5, 2019Inventors: YI-CHUN DU, CHENG-PANG SHIH, JING-YI CHEN

Publication number: 20170265799Abstract: A fetal movement measuring device includes a wearable article to be worn on a pregnant woman's abdomen, plural measurement units, and a mobile device pre-installed with a fetal movement algorithm. The measurement units are provided separately on the outer surface of the wearable article and each include a fetal movement sensor for sensing a dynamic physiological signal of the abdomen and a power supply element for supplying necessary electricity to the fetal movement sensor. The dynamic physiological signals sensed by the fetal movement sensors are received by the mobile device, processed with the fetal movement algorithm, and rid of synchronous signal components. Then, the fetal movement algorithm performs calculation on the remaining signal components to generate fetal movement information, which includes a fetal movement location and a fetal movement magnitude. Thus, each fetal movement is measured in a non-contact manner, and its location, obtained through asynchronous multipoint measurement.Type: ApplicationFiled: March 16, 2017Publication date: September 21, 2017Inventors: YI-CHUN DU, JHENG-BANG SHIH, BEE-YEN LIM, WEI-SIANG CIOU, CHUNG-YI CHIU

Publication number: 20150374896Abstract: A needle dislodgement and blood leakage detection device includes a sensor assembly including a flexible sensor and an alarm device to which the sensor assembly is mounted. The flexible sensor includes two blood leakage detection electrodes that circumferentially surround a needle piercing site. The blood leakage detection electrodes are contactable by a needle in a manner of crossing therebetween to get shorted or are contactable with blood leaking out of the needle piercing site to get shorted. The alarm device is positionable on a body surface of a patient and is electrically connected to the blood leakage detection electrodes so as to issue an alarm message when the detection electrodes are shorted. The flexible sensor has a thin plate configuration that is flexible allows the flexible sensor to be flat attached to the patient body surface and deformable with the bending of a limb of the patient.Type: ApplicationFiled: December 2, 2014Publication date: December 31, 2015Inventor: Yi-Chun Du
