Abstract

Medical infusion device provides drugs or fluids directly through a blood vessel. However, the occurrence of occlusion in the infusion device causes the incoming drug fluid does not to flow constantly, and pressure is formed on the infusion tube. When an infusion device has been used for a long time, there will be a change in the precision of the flow and pressure values. Furthermore, a calibration process must be carried out at least once a year. This research aims to design an infusion device analyzer which able to show parameters in a graphic equipped with occlusion parameters and Bluetooth communication in real-time to the computer unit. This study uses a solenoid valve for pressure simulation. The allowable occlusion limit is <20 Psi. The SKU 237545 sensor detects the water pressure that is blocked by the solenoid valve. Then the data will be displayed on the Parallax data acquisitions using Bluetooth communication. The Parallax data acquisitions will display real-time occlusion data, data averages, instant values, and graphs. The results of the IDA design, when tested using the Syringe Pump TOP 5300, obtained an average of 0.68 Psi. Meanwhile, when the IDA design was tested using the Infusion Pump 3300, it brought 0.73 Psi. Furthermore, it showed that the occlusion parameter was compared with the Fluke IDA 4, a mean error was 0.7 Psi. Therefore, it can be concluded that this IDA design can be used for calibration to see the feasibility of an infusion pump or syringe pump.

Abstract

Worldwide, over 4 million babies die within a month of birth each year. Of these, 3.9 million are in developing countries. A proportion approximately 25% of these deaths are due to complications of premature birth, most commonly inadequate thermoregulation, water loss, and neonatal jaundice. An infant incubator provides stable temperature, relative humidity, and airflow values. A periodical calibration should be applied on infant incubator to monitor the functionality. The study aims to develop a calibration device that measures temperature, humidity, airflow, and noise in the baby incubator based on an Android application with Bluetooth communication to improve the calibration monitoring process. This is to achieve a better performance of the conventional INCU analyzer. The contribution of this research is that the values of the temperature, humidity, airflow, and noise can be displayed on both devices, the INCU analyzer machine, and mobile phone; thus, the user can monitor the measurement activities wirelessly. Furthermore, the statistical calculation for all measurements can be saved on a mobile phone device. The main design consists of temperature sensor LM35, humidity sensor DHT22, airflow sensor MPX5010DP, an analog signal conditioning circuit, an Arduino Mega microcontroller, Bluetooth module HC05, and Android mobile phone. The resulting design was compared to the standard or calibrator INCU analyzer machine (Fluke Biomedical INCU II). This study found that the smallest error is -1.72%°C, -0.106 % RH, -1.727% dB, and <0.1% m/s for temperature, humidity, noise, and airflow parameters, respectively. After the evaluation process, this device can be used as an INCU analyzer to calibrate the infant incubator.

Abstract

The mesenchymal stroma harbours considerable population of stem cell-like cells with differentiation and self-renewal abilities that originate from several sources like amniotic fluid, Wharton’s jelly, umbilical cord etc. Mesenchymal Stem Cells (MSCs) are most commonly found in the perivascular niche. This multipotent progenitor cells have the ability to differentiate into mesodermal cell types such as adipocytes, chondrocytes and osteocytes. MSCs can also exert significant immunosuppressive and anti-inflammatory effects by interacting with lymphocytes from both innate and adaptive immune system. MSCs of fetal origins can go through same processes as MSCs derived from elsewhere. Before senescence, they make more cell divisions than adult MSCs of bone marrow or adipose tissue. The propitious properties of mesenchymal stem cells (MSCs), such as their ability to differentiate into diverse cell lineages and their regenerative properties, have intrigued researchers, whose work has provided fascinating perspectives on cell-based therapies for wide range of diseases. MSCs have a high potential for replication in vitro. International Society for Cellular Therapy (ISCT)-based MSC isolation has resulted in heterogeneous, nonclonal stromal cell cultures containing stem cells with various multipotent characteristics, committed progenitors, and differentiated cells. Nonclonal stromal cultures which are derived from bone marrow and other tissues are presently used as sources of putative MSCs for therapeutic aims. Also, MSCs have potential to endogenously repair as well as reduce the inflammatory responses that may lead to decreased morbidity and mortality rate of COVID-19. Herein, the MSC-based clinical prospects, clarifies, the recent clinical findings, therapeutic effects of MSC and clinical trials.

Abstract

Single use plastics are types of plastics discarded after one usage. They are everywhere you go because of their wide range of applications in life. In plastics, additives are incorporated to supplant properties of plastics. One of the common additives is the heavy metals, which could leach out along the plastics lifecycle, thereby creating a problem. This study was stimulated to determine the levels of heavy metals in selected single-use-plastics commonly in contact with food (as containers or wrappings or relations) in Sokoto. The Atomic Absorption Spectroscopy methodology was utilized to determine the levels of copper, chromium, lead, zinc and cadmium. The results for determination of selected heavy metals in selected single use plastics from Sokoto State University, Nigeria were revealed using atomic absorption spectroscopy. Therein, the concentrations of copper (Cu) ranges from 0.335+0.002 to 0.540+0.002(ug/kg), levels of cadmium (Cd) ranges from 0.0551+0.003 to 0.0041+0.0003(ug/kg), levels of chromium (Cr) ranges from 0.0959 +0.004 to 0.0265+0.001(ug/kg), levels of lead (Pb) ranges from -1.791+0.02 to -0.0706+0.008(ug/kg). Thus, the results revealed disparity in the levels of the analyzed heavy metals in the selected single use plastics. However, Cu concentration was the most elevated in plastic bottle (PB) and lowest in Takeaway (T); Cd was highest in Straw (S), and lowest in PB; Cr was highest in Ice cream cup (IC) and lowest in S; Pb was highest in PB, and lowest in S. The concentrations of Cupper, Chromium, Lead, and Cadmium in plastic bottle, Takeaway, Straw and lce cream cup, have shown disparity. However, Cu concentration was the most elevated in plastic bottle (PB) and lowest in Takeaway; Cd was highest in Straw, and lowest in PB; Cr was highest in Ice cream cup and lowest in S; Pb was highest in PB, and lowest in S. They levels determined are within the permissible limits.

Abstract

In the process of sterilizing medical devices, a sterilizer that is able to produce an accurate and even temperature is needed. If the resulting temperature is not in accordance with the regulated temperature and is not evenly distributed, it will be fatal/damage to the material sterilized. Periodic calibration should be applied to the sterilizer to monitor its function. Based on the research that has been done, no one has done research on making a temperature data logger with 9 channels to calibrate the sterilizer. This study aims to design a temperature measuring device with 9 sensors that can measure simultaneously, so that the accuracy and the distribution of the temperature of a sterlisator can be obtained. This tool used a K thermocouple-type temperature sensor which will detect the temperature and further enters the analog signal conditioning circuit. This then enters the ATMegga 2560 which has been programmed and processed in such a way, leading to the display of the temperature on the 4x20 character LCD. Temperature measurement data will be further stored to SD Card every 10 seconds in the form of a txt file. Tests were carried out on sterilizers, continued by comparison with the Madgetech OctTemp2000 data logger. Based on the measurement and comparison data, the average error was obtained at a temperature of 50ºC with the smallest error value of 0.7% and the largest error value of 3.9%. At a temperature of 100ºC, the smallest error value is 1.6% and the largest error value is 10.5%. Furthermore, at a temperature of 120ºC, the smallest error value is 0.0% and the largest error value is 8.5%. The module resulting from this research is stable in response to temperature by looking at the very small uncertainty value. This research can be further used to help analyze the temperature distribution in a sterilizer. With these measurement results, this study is considered having a fairly high error value at several measurement points.

Abstract

Electrocardiograph (ECG) is one of the diagnostic sciences that is often studied in modern medicine, used to detect damage to the components of the heart or disorders of the heart rhythm called arrhythmias. The purpose of this research is to develop an Electrocardiograph simulator that is equipped with arrhythmia. The main design consists of an Arduino Mega 2560 microcontroller, MCP4921 DAC (Digital to Analog Converter) circuit, a network resistor, and a sensitivity selection circuit. The MCP4921 type DAC converts the digital signal data into analog data which will then be forwarded to the resistor network circuit as a signal formation for each lead. The basic signal image data used for the formation of normal Electrocardiograph and arrhythmias were taken from the Electrocardiograph recorder using Phantom Electrocardiograph. Based on the readings on the Beat Per Minute setting of the module to the Beat Per Minute printout on the Electrocardiograph recorder, the error rate value for the Normal Sine Rhythm parameter is 0.790% for Beat Per Minute 30, 0.383% for Beat Per Minute 60, 0.535% for Beat Per Minute 120, 0.515% for Beat Per Minute 180 and 0.593% for Beat Per Minute 240. The error rate for the Arrhythmia parameter is 2.076% for ventricular tachycardia Beat Per Minute 160 and 0.494% for Supraventricular Tachycardia Beat Per Minute 200. The design of the Electrocardiograph simulator can simulate the signals of the human body and it can be used as a medium in the learning process in the world of health
