How Health IT is Helping to Improve the Lives of Patients

Health IT has essentially created a new ecosystem that helps improve the lives of patients while also making life easier for physicians. In the past, if a patient was sick or needed help with anything, they either had to make an appointment to see a doctor or drop in at the emergency room. Patients can now, however, take advantage of the technology available to speed up care. It is now possible for patients to receive a remote area diagnosis by receiving a consultation via video chat. Patients also have access to health wearables which can help monitor everything from heart rate to blood glucose levels. The data from these devices can be sent immediately to health care providers to ensure a patient is an inadequate health.

Humanized Test Subjects Essential for 21st Century Medical Research

The rat race continues for a cure to cancer, the solution to Alzheimer’s, and ways to treat and prevent countless other ailments, which, despite the advanced age we live in, have not been conquered by medical research. With only so much funding to go around, the millions of dollars required to bring new cures and treatments to market are being increasingly dispersed with caution. Competition for medical research funding has always been fierce, but it’s never been fiercer than it is today. Among the deciding factors for who gets what the ability to successfully replicate or near replicate the human model down to the point-one percent of DNA, which makes each person unique, can be the deciding factor. Despite the extreme similarities between the genetics of human beings, in addition to the similarities between humans and common test subject species such as mice and rats, the success of treatments depends significantly on the individual. In short, what works to cure cancer in traditional lab mice rarely cures cancer in humans, and even what works for one person may not work for another. Such is the vital importance that point-one percent difference in DNA plays.

A basic understanding of Medical Research

What is medical research? Medical research can be described as any research conducted with the aim of supporting and furthering the development of medical knowledge. In recent years, medical research has directly resulted in the emergence of countless new treatments and vaccines and has helped to increase scientists’ understanding of the workings of the human body and the mechanisms of diseases.

New Technological Advancements Improving Health Sector

Imagine being diagnosed with a dreading disease. One that can literally take away the joy of life. One that can push you in a corner and make you feel irrelevant of the surroundings. But hey, you are not in the 20th century this is the age of technology. This is an era where medicines are not generic but tuned according to the body they are being administered into. No, this is no longer about being in the typical era of loneness; it is about advancing now. Protracted and more serious diseases these days are cured through this form of treatment called precision medicine. For say and god forbid if you are diagnosed with cancer, the doctor will advise you with precision medicine. This type of cutting-edge treatment uses your genetic information, along with cues from your lifestyle and environment, to prevent and treat disease.

The U.S. and the Changing World of Medicine

There is no doubt that as everything else is evolving with new technology, medicine is too. The issue is that in the US, our medical system is broken, and the insurance companies are too rigid. Doctors and other medical personnel have managed to work despite these difficulties and still provide excellent patient care, along with successful new techniques. With the advance of biomedical research, doctors will be able to better tackle health issues in ways that are cost-effective. Automation is only one area where there is new technology coming to the fore. Because of this advancement, linear actuators are being used more often than hydraulic and pneumatic systems. They range in size from very small to huge ones. Aside from the changes that technology has seen, there are quite a few other reasons that have made these actuators necessary, such as the ever-growing need for power-assisted seating and motorized wheelchairs.

3 new ways technology is helping to advance medicine

Imaging Cameras improving cancer surgery Every year, 14 million people are diagnosed with cancer; of those, around eight million will die. Cancer is one of the leading causes of death worldwide; across the globe, doctors and scientists are fighting to reduce the number of cancer deaths by detecting cancer early and promoting new ways of battling it. In the past, imaging technologies such as radiography, magnetic resonance imaging, and computed tomography have proved vital in the fight against cancer, helping doctors to diagnose the disease quickly to increase the chance of recovery. Now, near-infrared fluorescence (NRF) has emerged as a new, powerful imaging tool in the battle against cancer. NRF imaging is used during surgery to enable surgeons to distinguish between healthy tissue and cancerous tissue easily. Surgery is a highly effective method of treating cancer patients, but its success rate depends largely on how much of the cancer is removed; if cancer cells remain in the body after surgery, the surgery’s success rate is greatly diminished. Advocates of NRF hope the technique will give surgeons greater visibility of cancer margins and increase their ability to remove cancerous tissue precisely. Companies such as andor.com are researching how we can implement…

Ultrasound wave propagation and parameters

Ultrasound waves are acoustic pressure waves that interact with propagation media. Ultrasound visualization is typically based on wave reflectance from regions with different acoustic properties. When a wave meets different acoustic media, part of it transmits further while others reflect. This happens due to different acoustic impedance. The ration between reflected and transmitted energy purely depends on the difference in acoustic impedance in both regions. As you can see each material can be characterized by its acoustic impedance Z which is equal to ultrasound speed v and material density r.

Using wavelet transform in biomedical engineering – heart signal analysis

In previous post, we cleared out that wavelet transform is used to analyze short-time and non-stationary signals. Since base wavelet function has to parameters – translation and scaling, it is possible to achieve good time and frequency localization. In other words, we can equally analyze the slow signal and fast signal structures without losing resolution and so evaluate signal frequency characteristics and time dynamics. Heart signal analysis is one of the most common problems in biomedical engineering. Practically every part of ECG signal carries some sort of information about heart conditions, possible pathologies, and diseases. So equally, frequency and timing characteristics of ECG signal is essential. As you know standard ECG signal consists of several typical waveforms like P-QRS-T, where in P and T waves low frequency component dominates, and in QRS, mid and high. The common condition of hear is myocardial ischemia when blood flow through coronary arteries to the heart is reduced, what prevents receiving enough oxygen. This can damage the heart muscle and lead to a heart attack. In order to notice this pathology it is we need to analyze S-T segment of ECG waveform. Insignificant changes in the signal can indicate ischemia. In order to find…

Automation In The Medical Field

The advancement in technology and medical automation has led to the increased use of linear actuators in the medical field that has continued to render pneumatic and hydraulic systems obsolete. The use of actuators will vary depending on their sizes that range from the tiny ones (2” strokes) to the large ones (24” stokes). Other than changes in technology, several other contributing factors have necessitated increased actuators in the health sector. Key reasons for the increased usage of actuators in the medical field First, the size of a machine is a factor to consider when deciding the technology to use. Actuators are appealing in size, especially compared to hydraulics that can yield a similar amount of strength. Secondly, when in action, actuators produce less noise as compared to pneumatic and hydraulic solutions. The hiss and gurgle sound found in pneumatics and hydraulics do not exist in actuators that have triggered their continued use. The photo below is a sample of the actuator’s wheelchair. Another positive factor that has contributed towards the use of actuators is that they are precise. Pneumatic pistons can be positioned correctly at either full extension or retraction. Lastly, actuators have fewer moving parts implying that fewer…
