使用光學傳感器進行無創血糖監測
標簽:血糖
積分:1 類型:應用文檔上傳者:太白金星上傳時間:2021-06-30
簡介: Over 30.3 million Americans currently have diabetes and a further 1.5 million are estimated to be diagnosed every year. Diabetes remains the 7th leading cause of death in the U.S. For diabetics, managing blood glucose levels is extremely important to maintain their health as high levels of glucose in the blood for extended periods can be fatal. Current glucose monitoring methods are very invasive and can the limit physical activities of users. This thesis investigated using a low power optical system to noninvasively read blood glucose levels to determine if this is a feasible method for glucose detection. A low power system is key in this design as it would allow for a smaller, portable unit that average diabetics could use daily. This thesis showed there was a correlation between the optical system and a standard glucose meter.

如何使用 8 位單片機設計一款靈活的低成本血糖儀
標簽:血糖
積分:1 類型:應用文檔上傳者:太白金星上傳時間:2021-06-30
簡介:世界上的糖尿病患者約占人口總數的8.5%,現已成為第八大主要致死原因。據世界衛生組織估算,糖尿病將在2030年升至第七位。這種增長趨勢可從近年來的統計數據看出:糖尿病的死亡病例從2000年的100萬增至2011年的140萬。 控制糖尿病的一種主要方法是使血糖盡可能地保持正常水平。這導致對血糖儀的需求日益增加。 血糖儀是一種用于確定溶液中葡萄糖濃度的醫療設備。葡萄糖濃度的單位是毫克每分升(mg/dl)或毫摩爾每升(mmol/l)。血糖儀已成為糖尿病患者使用的家用血糖監測設備的重要組成部分。一天內可進行多次測量。 大多數血糖儀基于電化學技術。這些血糖儀采用電化學試紙進行測量。將一小滴待測溶液置于一次性試紙上,血糖儀將利用該試紙來測量葡萄糖。在葡萄糖的電化學測量中,最常用的兩種方法是比色法和電流法。 在比色法中,LED或光傳感器等構成模擬接口。跨阻放大器用于測量葡萄糖濃度。利用顏色反射率原理,根據光度測定法來確定試紙反應層的色彩強度。血糖儀生成葡萄糖濃度的測量值。 在電流法中,使用毛細管吸取試紙一端的溶液。此試紙還包含一個酶電極,其中含有葡萄糖氧化酶等試劑。葡萄糖在酶的作用下發生化學反應并在化學反應期間生成電子。隨后測量流經電極的電荷,電荷量與溶液中的葡萄糖濃度成正比。此外,還會測量環境溫度以補償溫度對反應速率的影響。大多數血糖儀采用此方法。圖1給出了試紙的工作原理。

Non-invasive Blood Glucose Level Monitoring System for Diabetic Patients using Near-Infrared Spectro
標簽:血糖
積分:1 類型:應用文檔上傳者:太白金星上傳時間:2021-06-30
簡介: This paper describes a non-invasive method for monitoring blood glucose levels of diabetic and non-diabetic peoples. A non-invasive method for glucose monitoring provides adequate control and greatly reduces the complications in diabetic patients; and consequently reduces the health care costs. Non-invasive method is advantageous as the possibilities of infections get reduced and even there is no pain of pricking the blood. The proposed method uses near infrared sensor for determination of blood glucose. Near-Infrared light is sent through the fingertip before and after blocking the blood flow. By analyzing the voltage variation received after transmission through fingertip, approximate glucose level is predicted. The obtained glucose level is further transmitted to the smart android app for further analysis and storage of the data.

Low Power Analog Techniques for Wearable Biosensors
標簽:血糖
積分:1 類型:應用文檔上傳者:太白金星上傳時間:2021-06-30
簡介:Wearable devices are receiving more and more attentions owing to their affordability, novel applications and convenient form factors. The market for wearable sensors is expected to grow at a Compound Annual Growth Rate (CAGR) of 19.15% from 2019 to 2025 to reach $31.96 billion by 2025. most wearable devices today only measure physical or electrophysiological parameters such as motion, pressure, temperature, ECG, or EEG [1]. While these parameters may be useful for monitoring general wellbeing and a few specific diseases, acquiring a more comprehensive picture of underlying physiology via additional wearable sensors will provide significant value to a much wider range of users. Nowadays, wearable devices that are embedded in textiles or directly mounted on the human skin are trending in the field. These improvements necessitate us moving forward to investigate flexible and light instrumentation circuits as well as energy sources. This thesis shows some of the efforts towards the next genera1 tion of these wearable devices. On the other hands, the battery life time of the wearable sensor device is of the tremendous importance.

First Clinical Experience with Retrospective Flash Glucose Monitoring (FGM) Analysis in South Africa
標簽:血糖
積分:1 類型:應用文檔上傳者:太白金星上傳時間:2021-06-30
簡介: Background: In 2014, an innovative blinded continuous glucose monitoring system was introduced with automated ambulatory glucose profile (AGP) reporting. The clinical use and interpretation of this new technology has not previously been described. Therefore we wanted to understand its use in characterizing key factors related to glycemic control: glucose exposure, variability, and stability, and risk of hypoglycemia in clinical practice. Methods: Clinicians representing affiliated diabetes centers throughout South Africa were trained and subsequently were given flash glucose monitoring readers and 2-week glucose sensors to use at their discretion. After patient use, sensor data were collected and uploaded for AGP reporting. Results: Complete data (sensor AGP with corresponding clinical information) were obtained for 50 patients with type 1 (70%) and type 2 diabetes (30%), irrespective of therapy. Aggregated analysis of AGP data comparing patients with type 1 versus type 2 diabetes, revealed that despite similar HbA1c values between both groups (8.4 ± 2 vs 8.6 ± 1.7%, respectively), those with type 2 diabetes had lower mean glucose levels (9.2 ± 3 vs 10.3 mmol/l [166 ± 54 vs 185 mg/dl]) and lower indices of glucose variability (3.0 ± 1.5 vs 5.0 ± 1.9 mmol/l [54 ± 27 vs 90 ± 34.2 mg/dl]). This highlights key areas for future focus. Conclusions: Using AGP, the characteristics of glucose exposure, variability, stability, and hypoglycemia risk and occurrence were obtained within a short time and with minimal provider and patient input. In a survey at the time of the follow-up visit, clinicians indicated that aggregated AGP data analysis provided important new clinical information and insights

AN OPTICAL METHOD FOR MEASURING BLOOD GLUCOSE NON INVASIVELY
標簽:血糖
積分:1 類型:應用文檔上傳者:太白金星上傳時間:2021-06-30
簡介: This paper investigates a possible method of measuring the Non Invasive Blood Glucose Concentration Level(NI-BGC), with the main objective of providing Preventive care against the onset of diabetes by frequent selfmonitoring. This paper rationalizes a method for NI-BGC through the use of Near Infrared Light (NIR) byemission from LASER and tries to find a relationship between absorbance of NIR by glucose. An apparatusbased on transilluminated LASER beam via the sensitive part of human finger is considered. This devicedepends upon atomic gas Helium-Neon (He-Ne) laser operating at a wavelength of 620-630 nm. Duringmeasurement the index finger is inserted into the sensing unit and the LASER light is passed through it, and thetransilluminated optical signal is detected by a photodiode and an equivalent electrical signal is obtained. Withthe help of look up table this electrical value is displayed in the form of direct blood sugar in mg/dL(milligram/deciliter).The result obtained shows a linear relationship of increase in glucose level as transmittedlight intensity level decreases.

簡介: Over 17 million individuals in the United States are affected with diabetes. While incurable,diabetes is manageable with proper monitoring. Currently, monitoring is performed through useof stand-alone blood glucose meters that allows a diabetic to monitor blood sugar levels on aperiodic basis; the meter readings are either recorded into a log book or uploaded via proprietarysoftware to a desktop computer. The purpose of this senior design project was to offer a newapproach to patient self-monitoring through the development of a diabetes management systemusing the Handspring Visor Personal Digital Assistant (PDA). The design consists of aSpringboard module containing blood glucose metering hardware and an accompanying softwarepackage that operates the module and allows for the storage and processing of data. Thefollowing sections outline the process followed by the senior design group in their developmentof the design.
