This paper introduces programmable filter technology to traditional hardware for heat-rate detection, then the midfrequency of R wave filter becomes regulable resultingly, and thus a heart rate detection system can precisely position R waves and calculate heart rates of different animals.

Objective:To analyze the hotspots and frontiers of diabetic peripheral neuropathy nursing research in the past decade in China, and to provide nursing staff with a reference basis for understanding and grasping the direction of research.Methods:The literature related to diabetic peripheral neuropathy nursing from January 1, 2012 to December 31, 2021 was searched through China Journal Full Text Database, China Biomedical Literature Database, CQVIP, and Wanfang, and visualized and analyzed by using CiteSpace software.Results:A total of 763 articles were included in the literature, and the number of articles was analyzed to show a significant upward trend in 2018-2021, with the most articles by authors being 4 each by Liu Dan and An Caixia, and the most articles by institutions being 6 and 5 by Nanjing Chinese Medicine Hospital and Shanghai Jiading District Chinese Medicine Hospital, respectively, with research hotspots being complications related to diabetic peripheral neuropathy, rehabilitation care, and special Chinese medicine care techniques, and research frontiers being quality of life and neurological function.Conclusions:The research base of diabetic peripheral neuropathy is weak, and researchers should focus on the frontiers of international research hotspots in diabetic peripheral neuropathy care to help nursing research produce prospective, high-impact research results and improve patient clinical outcomes.

Objective:To analyze acupoint massage treatment of diabetic peripheral neuropathy point selection rules and practices for clinical treatment to provide evidence-based.Methods:Data mining was used to retrieve the relevant literature on acupressure for diabetic peripheral neuropathy from China Journal Full Text Database, Wanfang, VIP, and China Biomedical Literature Database, with a search time frame from the date of database creation to April 27, 2022. An Excel thematic database was created, then clustering analysis was performed by SPSS 25.0.Results:A total of 104 articles were included in the literature, with 49 acupoints. The commonly used acupoints in the lower limbs were Zusanli, Sanyinjiao, Taixi, Yongquan, etc. The commonly used acupoints in the upper limbs were Hegu, Quchi and Neiguan. The commonly used acupoints in the trunk were Guanyuan, Zhongwan and Shenshu. The frequency of the five acupoints was the highest, accounting for 59.40%(335/564). The meridians were mainly the spleen meridian of foot Taiyin, the kidney meridian of foot Shaoyin and the stomach meridian of foot Yangming, among them, the frequency of the spleen meridian of foot Taiyin was the highest, accounting for 22.7%(128/564). Three effective clusters were obtained by analyzing massage acupoints and manipulations.Conclusions:According to the analysis, high-frequency acupoints are mainly distributed in the three meridians of foot Taiyin spleen meridian, foot Shaoyin kidney meridian and foot Yangming stomach meridian. In the future, acupoint selection and massage techniques can be further standardized and supplemented by acupoint massage along meridians to explore its clinical effect on diabetic peripheral neuropathy.
