Design and implementation of Internet of Things for emergency medical devices based on cloud-edge-device architecture / 生物医学工程学杂志

Internet of Things (IoT) technology plays an important role in smart healthcare. This paper discusses IoT solution for emergency medical devices in hospitals. Based on the cloud-edge-device architecture, different medical devices were connected; Streaming data were parsed, distributed, and computed at the edge nodes; Data were stored, analyzed and visualized in the cloud nodes. The IoT system has been working steadily for nearly 20 months since it run in the emergency department in January 2021. Through preliminary analysis with collected data, IoT performance testing and development of early warning model, the feasibility and reliability of the in-hospital emergency medical devices IoT was verified, which can collect data for a long time on a large scale and support the development and deployment of machine learning models. The paper ends with an outlook on medical device data exchange and wireless transmission in the IoT of emergency medical devices, the connection of emergency equipment inside and outside the hospital, and the next step of analyzing IoT data to develop emergency intelligent IoT applications.

Curative effect of Chinese medicine for invigorating spleen and eliminating phlegm, promoting blood circulation and removing blood stasis combined with western medicine on obesity type PCOS infertility / 中国现代医生

Objective To investigate the clinical effects of Chinese medicine for invigorating spleen and eliminating phlegm, promoting blood circulation and removing blood stasis on infertility of obesity type polycystic ovary syndrome (PCOS). Methods A total of 96 patients with obesity type PCOS infertility who were admitted to our hospital from January 2015 to May 2016 were selected, and randomLy divided into study group and control group, with 48 cases in each group. The control group was given routine treatment of western medicine, and the study group was further given Chinese medicine for invigorating spleen and eliminating phlegm, promoting blood circulation and removing blood stasis. The levels of serum estradiol(E2), luteinizing hormone (LH), follicle stimulating hormone (FSH) and testosterone (T) were compared before and after the treatment, and the clinical curative effect, periodic ovulation and pregnancy situation were compared. Results The levels of serum E2 and FSH in both groups after treatment were significantly higher than those before treatment(P＜0. 05). The study group was significantly higher than the control group(P＜0. 05); serum LH and T levels after treatment in both groups were significantly lower than those before treatment(P＜0. 05), and the study group was significantly lower than the control group (P＜0. 05); there were significant differences in the distribution of clinical efficacy between the two groups(P＜0. 05), and the total effective rate in the study group was significantly higher than that in the control group(P＜0. 05); the periodic ovulation rate and pregnancy rate in the study group were significantly higher than those in the control group(P＜0. 05). Conclusion Chinese medicine for invigorating spleen and eliminating phlegm, promoting blood circulation and removing blood stasis can effectively regulate the sex hormone level in the patients with obesity type PCOS infertility, with significant curative effect, which can promote ovulation and improve pregnancy rate, and is worthy of promotion.

Design and application of digital manometer for air-pocket in manual air-way / 医疗卫生装备

This paper discusses the design of a special digital manometer for air-pocket in manual air-way. Integrated silicon pressure sensor MPX5010 with high precision and sensitivity is adopted in the device. It can not only measure and display air pressure of air-pocket,but also give the alarm for excessive pressure,thus providing a timely and convenient way for clinician to control air-pocket pressure,which ensures the safety and precision for clinic.
