Fortunately for humanity, medicine is developing very rapidly at the present stage. The aim of innovations in medicine is to fight serious diseases and improve the quality of life of people.
A few decades ago, no one could even dream of such diagnostic manipulations as ultrasound, computer tomography, Doppler, heart echocardiogram and many other things that modern humans find quite common. But medicine is looking ahead, and new medical innovations are emerging.
The most advanced inventions to date
Transparent internal organs
At Stanford University invented a new technology that makes it possible to see the organs as if they were transparent, so that scientists can study them from the inside. This technique is called CLARITY. The experiments were conducted on laboratory rodents and on the bodies of people who wished to leave them for medical research. At first, a hydrogel solution was introduced into the organ.
The organ was then placed in a certain environment. The gel joins various cells of the organ, except lipids. The scientists then extracted the non-aligned elements and obtained a transparent organ model. This technique has many advantages, among the disadvantages can be called that it is used only at a certain thickness of tissue.
Scientists at the University of Groningen have developed a new technology that helps to find the source of bacterial infection in advance. This is especially true for people who have medical implants that can develop dangerous bacterial infections. It is often not possible to diagnose this process at an early stage, and the spread of infection can be fatal.
They have stained the antibiotic with a fluorescent dye. Once the antibiotics have reached the site of bacterial infection, they have infiltrated the bacterial cells and the bacteria themselves have become glowing. The researcher photographed the area with a camera detecting fluorescence. The method is not yet fully developed and has a number of shortcomings, but scientists are struggling to improve this technique.
For a person with diabetes, measuring glucose levels is a vital procedure. Today, a conventional glucose meter shows the blood glucose level when a certain glucose meter sensor comes into contact with a test strip that has a drop of blood on it. The new laser glucose meters make it possible to do without injections.
Now it is possible to determine the blood level in the blood simply by passing the laser over the skin, and the molecules of glucose create a special sound, its intensity is determined by the level of glucose. The biggest advantage of this method is that diabetics do not have to break the integrity of the skin every time you need to determine the level of glucose, which is especially valuable.
These new soft toric lenses are shown for astigmatism. Unlike conventional contact lenses, they are thick and spherical in shape, which gives them two advantages: they correct astigmatism and the associated myopia or hyperopia.
In order to correct astigmatism these lenses must be fixed in a certain place, so the lenses have a special mechanism for fixation in a certain position. Such lenses are selected and manufactured individually.
CyberKnife is a radiosurgical system used to remove tumors of various origins. This equipment is manufactured by Accuray.
The device has two main elements:
-a linear accelerator
-an energy directing robotic device
“Smart Bracelet” is a device that allows you to collect information about a person’s health and motor activity. According to the developers, this bracelet is a fully open platform for monitoring the state of the body.
What can a “smart bracelet” do? The bracelet measures heart rate, body temperature, and oxygen saturation. The data is transmitted via Bluetooth to a mobile device or computer.
Organ printing on a 3D printer
Bioprinting is a technology based on the creation of workable organs. Today, implants and prosthetic devices are already being printed on 3D printers, and the next step is the printing of organs such as the heart, kidneys and liver.
In the future, artificially grown organs can be introduced into the human body. Perhaps these organs will even outperform the functions of natural human organs.
Bionic eye is a device that helps blind people partially restore their sight. Bionic eye is an artificial visual system. It is a retinal prosthesis, surgeons place it in the eye, which has suffered damage. This eye is a polymeric matrix with photodiodes. Signals produce effects on neurons that have survived in the retina.A built-in camcorder records the image and stores it in the processor.
From there, the signal is sent to the receiver and photo sensor, which is embedded in the retina. The optical nerve transmits electrical impulses to the brain.As a result of the introduction of such an eye a person gets the opportunity to see the world in black and white light and is blurred, but people who were previously blind were very happy and this opportunity.
