This paper presents a new optical, multi-functional, high-resolution 3-axis sensor which serves to navigate and can, for example, replace standard joysticks in medical devices such as electric wheelchairs, surgical robots or medical diagnosis devices. A light source, e.g. a laser diode is affixed to a movable axis and projects a random geometric shape on an image sensor (CMOS or CCD). The software in the downstream microcontroller identifies the geometric shape’s center, distortion and size, then calculates X, Y, and Z coordinates. These coordinates can then be processed in attached devices. The 3-axis sensor is characterized by its very high resolution, precise reproducibility and plausibility of the coordinates produced. In addition, optical processing of the signal provides a high level of safety against electromagnetic and radio frequency interference. The sensor presented here is adaptive and can be adjusted to fit a user’s range of motion (stroke and force). This recommendation aims to optimize sensor systems such as joysticks in medical devices in terms of safety, ease of use, and adaptability.

Today’s wearable medical devices are becoming popular because of their price and ease of use. Most wearable medical devices allow users to continuously collect and check their health data, such as electrocardiograms (ECG). Therefore, many of these devices have been used to monitor patients with potential heart pathology as they perform their daily activities. However, one major challenge of collecting heart data using mobile ECG is baseline wander and motion artifacts created by the patient’s daily activities, resulting in false diagnoses. This paper proposes a new algorithm that automatically removes the baseline wander and suppresses most motion artifacts in mobile ECG recordings. This algorithm clearly shows a significant improvement compared to the conventional noise removal method. Two signal quality metrics are used to compare a reference ECG with its noisy version: correlation coefficients and mean squared error. For both metrics, the experimental results demonstrate that the noisy signal filtered by our algorithm is improved by a factor of ten.

Abstract Background Task shifting could help address limited human resources available for the delivery of quality health care services in low-resource settings. However, the role of medical devices in supporting task shifting is not fully understood. This study aimed to 1) define “task-shifting medical devices” and 2) identify product characteristics to guide the design and development of task-shifting medical devices. A three-part survey questionnaire comprising open-ended, rank-ordering, and multiple-choice questions was disseminated to healthcare professionals worldwide. The survey included questions to capture stakeholders’ general understanding of and preferences for task shifting in medicine and public health, and questions to define task-shifting medical devices and identify desirable product characteristics of task-shifting medical devices. Results Task-shifting medical devices were defined by respondents as “devices that can be used by a less specialized health worker”. Aside from safe and effective, both essential characteristics for medical devices, easy to use was the most cited product characteristic for a task-shifting medical device. Responses also emphasized the importance of task-shifting medical devices to enable local agency, such as peer-to-peer training and local maintenance. Several additional frequently mentioned attributes included low cost, contextually appropriate, maintainable, capable of using an alternative power source, easy to understand, easy to learn, reusable, and easy to manage throughout its use cycle. Conclusion This study defines and characterizes task-shifting medical devices based on healthcare professionals’ responses. Ease of use was identified as the most important characteristic that defines a task-shifting medical device, alongside safe and effective, and was strongly associated with enabling peer-to-peer training and maintainability. The findings from this study can be used to inform technology product profiles for medical devices used by lower-level cadres of healthcare workers in low-resource settings.

Today, there is a need to introduce medical devices into everyday medical practice with the goal to self-administer injectional drugs. The speed and safety of auto-injectors / pre-filled syringe pens use (AI/PFS) is the introduction of an injectional form drug in a special medical device, which allows patients to enter a pre-designated therapeutic dose due to the characteristics of the structure of the product, automatic dosing, data of the interactive display on some devices, comfortable design, etc. Considering that AI/PFS were developed to improve the quality of life of patients with various pathological conditions, therefore the creation of affordable medical devices for low-income groups of the population is relevant today. Also an actual issue is the provision of high-quality first-aid kits for soldiers, which is a vital component for medical care in the context of active combat conditions and the lack of the required number of field hospitals.The speed of administration, the onset of effect and ease of use provides significant advantages for AI / PFS. Therefore, the issue of affordability for the low-income groups of the population and the army with the necessary drugs should be sufficiently supported by state regulation.Purpose of study – study of the international experience in the implementation and use of drugs (drugs) in the form of affordable, safe and effective modern dosage forms in the form of autoinjectors.Materials and methods – foreign and domestic literature on the use of AI/PFS in complex and monotherapy treatment of various diseases. State registries of medicines of Ukraine, the USA and some EU countries. The study used systematic, statistical and comparative analyzes, as well as the generalization of information. The data used is freely available among various medical scientific and metric bases, the Internet and international scientific conferences.The analysis of the use of AI/PFS indicates that today the world market of medicines and medical devices contains a large number of drugs under different trade names. However, many patients in the world refrain from using these dosage forms due to the significant cost of medical devices, which makes impossible the required regular use of such drugs for the low-income population groups. This is a significant disadvantage, since AI / PFS is implemented to correct not only chronic diseases such as rheumatoid arthritis, multiple sclerosis, but also to provide emergency careinurgent conditions (anaphylactic reactions, intense pain, etc.).In the global market for drugs and medical devices, injectable medicines in the form of AI/PFS are widely represented. The effectiveness of the use of such devices indicates the advantages and prospects for the use of existing AI/PFS on the global market for patients and medical personnel. Today, the most commonly used drugs in AI/PFSare for the treatment of diabetes, emergency conditions in civil and military medicine, chronic diseases of various etiologies, pediatric practice. The use of AI /PFS significantly improves patient compliance for the treatment of chronic diseases due to ease of use and reduction of adverse reactions at the site of administration. Most of the analyzed sources indicate a low level of economic affordability of drugs in the form of AI/PFS for the population and the government sector of drug supply due to the high cost of the medical devices, compared to traditional syringes. But the results of the study indicate a high level of advantages and prospects in the use of drugs in AI/PFS in medical practice for both medical personnel and patients.

Ultraviolet radiation (UVR) from all three waveband regions of the UV spectrum, UVA (320-400 nm), UVB (290-320 nm), and UVC (200-290 nm), can be emitted by some medical devices and consumer products. Sunlamps can expose the blood to a considerable amount of UVR, particularly UVA and/or UVB. The percent transmission of each waveband through the epidermis to the dermis, which contains blood, increases in the order of increasing wavelength: UVC (10%) < UVB (20%) < UVA (30%). To investigate the effects of UVR on white blood cells, we chose transmission electron microscopy to examine the ultrastructure changes in L5178Y-R murine lymphoma cells.

Bacterial Biofilm

Studies of bacterial behavior in many environments have shown that most organisms attach to surfaces, forming communities of microcolonies called biofilms. In contaminated medical devices, biofilms may serve both as reservoirs and as inocula for the initiation of infections. Recently, there has been much concern about the potential of dental units to transmit infections. Because the mechanisms of biofilm formation are ill-defined, we investigated the behavior and formation of a biofilm associated with tubing leading to the water syringe of a dental unit over a period of 1 month.
