Under the guidance of Professor Xu Lisheng, three graduate students of the School of Biomedical and Information Engineering of Northeastern University, Li Yinan, Guan Yaofeng and Zheng Lingyi, successfully developed the wrist wearable cardiovascular disease intelligent warning device and won the third national biomedical science The first prize of the Engineering Innovation Design Competition.
ECG, pulse and blood pressure parameters can effectively reflect the cardiovascular health of the human body. In view of the shortcomings of the traditional body numerical measuring equipment, such as large size and non-portable, the "Wrist-type wearable cardiovascular disease intelligent early warning device" developed by the team can collect key physiological parameters such as human ECG, pulse and blood pressure through the form of a wristwatch. After that, the collected data is analyzed in real time on the mobile phone client to show the cardiovascular health status and realize the monitoring and early warning of family health.
According to Guan Yaofeng, the device has been able to accurately convert the collected physiological signals into data and images through practice verification, and to visualize the measurement results in the Android system. The device is composed of a signal collecting device and an Android intelligent analysis system. The signal collecting device adopts a dry electrode piece, which has the advantages of high durability, accurate acquisition signal, etc., and is wrapped with a metal fabric with good flexibility to facilitate wearing. The device can input the collected data into the Android system, automatically analyze the data by using the internal algorithm of the Android system, and display the heart rate and blood pressure analysis results by waveform, and provide an early warning prompt for the abnormal detection result.
"In the contest defense session, the judges offered to conduct physical examination as the tester. The test images of this equipment and the results of the other medical equipment tests by the judges were basically the same, which won the full affirmation of the judges." Zheng Lingyi said.
Wearable detection equipment has gradually become an indispensable part of the medical field. The device is small and convenient, easy to operate, and has broad application prospects in daily home monitoring. At the same time, the characteristics of real-time monitoring of the device can systematically reflect the heart rate status of the user, provide a more accurate and comprehensive judgment basis for disease diagnosis, and have important application value in clinical medicine.

Drug intermediates -Pharmaceutical intermediates: A material that is produced during a process step of the drug substance and must undergo further molecular changes or refining before it becomes a drug substance. The intermediates can be separated or not separated.
Active Pharmaceutical Ingredient (APIS)(or Drug Substance) : Active Pharmaceutical Ingredient (API)(or Drug Substance) : Any substance or mixture of substances intended to be used in the manufacture of pharmaceutical products and, when used in pharmaceutical products, to be an active ingredient in pharmaceutical products. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, management or prevention of disease, or can affect the function and structure of the body. As can be seen from the definition, the Intermediates APIS is a key product of the previous process of manufacturing the API and has a different structure from the API
Finally, for example, amoxicillin capsules are called preparations, amoxicillin is called APIS, and 6-APA is called Veterinary Intermediates APIS.
Penicillin potassium for injection is called preparation, penicillin potassium is called Veterinary raw materials, and green potassium industrial salt is called intermediate
