Medgadget is a medical technology information website in the United States that has been focusing on medical technology, products and innovation for ten years. Looking back at the past year's report, Medgadget rated the most exciting, innovative, and patient-friendly new trends and new products in 2014.
Flexible microelectronics
Flexible Microelectronics can adapt to the shape of irregular human tissues and cooperate with the movement of these tissues to achieve sensing capabilities, and even respond to different physiological parameters in the future.
In this regard, Google contact lenses are a representative. Google announced in January last year that it is developing a smart contact lens that can help diabetics monitor blood sugar levels by analyzing the glucose content in the tears of the wearer, thus eliminating the pain of taking blood tests from diabetic patients. The contact lens has tens of thousands of tiny transistors and a hairline-like antenna that is wirelessly sent to mobile devices such as smartphones.
John Rogers, a professor at the University of Illinois, and a research team at the University of Washington developed a flexible collar that wraps around the heart of a beating rabbit and monitors its electrical activity in 3D. In the near future, this technology may be used for highly accurate perception and response to arrhythmias.
In addition, Professor Rutgers has developed a flexible skin "patches" that record ECG and EEG signals and send them wirelessly to smartphones or other devices.
3D printing
Recently, 3D printing has received great attention. In the past year, we have seen 3D printing technology applied to replace bones, install prostheses for injured people in theaters, and surgery.
As we have reported, the “Project Daniel†project in South Sudan and a similar project jointly launched by the University of Toronto and the Autodesk Uganda Research Center are providing 3D printed prosthetic services to locals. Without the cost and external expertise, a team of trained local engineers can customize the prosthetic for those injured in the theater.
The more aggressive use of 3D printing in the medical field also included the printing of a new skull for a woman in the Netherlands and a facial plastic surgery for a man in the UK. In addition, in a facial transplant, the doctor also printed a 1:1 skull based on the patient's CT scan.
In China, the 3D printed titanium spine was successfully transplanted to patients, solving the problem of transplanting under rare orthopedic conditions and unusual anatomical structures. At the University of Michigan, a 3D printed tracheal splint was used in the child's respiratory tract to save his life.
Although 3D printing is still in the pre-clinical trial phase, we believe that the day that is universally applied to humans will come soon.
Intelligent induction prosthesis
Les Baugh, the American man, lost his arms 40 years ago because of an electrical accident, but the Johns Hopkins University Applied Physics Laboratory (JHUAPL) installed two prosthetic limbs with "ideal" control.
Doctors must activate the dead nerves and dock them with the nerves of the chest so that he can control his prosthetic limbs through "ideas." After training, Buff has been able to control his arms for some complex tasks. Although the system is still in its infancy, there is no doubt that future prosthetics will have greater “autonomyâ€.
Researchers at the Federal Institute of Technology in Lausanne (EPFL) and the University of Pisa (ANASA) in Italy have developed a new type of intelligent prosthetic with a tactile sensor at the fingertip that senses the object being touched. By connecting with the human nerves, the prosthetic can feed back information such as the softness and shape of the object to the wearer, and thus can simulate the touch of the human hand to a certain extent.
Thanks to Battelle's "Neurobridge" technology, Ohio's non-profit research and development agency, a four-legged man can lift his arms again. "Nerve Bridge" is an electronic nerve branch for patients with spinal cord injury. It is like a high-definition muscle stimulation "tube sleeve" that connects the patient's brain and muscle directly so that they can achieve the right way. Functional control of one's own limbs. Today, the man has been able to turn his wrist, make a fist, close his fingers, etc. It looks like a normal arm.
XStat Rapid Hemostasis System
If the patient has severe bleeding, whether on the battlefield or in an ambulance, it is not enough to rely solely on gauze and external pressure. Xstat, developed by American company RevMedx, is a new type of hemostatic sponge syringe that can inject sponges containing antibacterial coagulant and anti-inflammatory effects into wounds a few inches deep. It can effectively stop bleeding within 15 seconds, compared with traditional stoppers. Gauze or wound compression is more effective.
As a syringe, Xstat is easy to use, especially when time is tight. To ensure that no residue is forgotten in the injured, each of Xstat's sponges is engraved with a large blue X, which can be seen under X-rays.
Diabetes monitoring / glycemic control
As we said earlier, Google's smart contact lenses can help diabetics monitor blood sugar levels by analyzing the glucose content in the wearer's tears. But now, they still need to collect blood daily. As a result, Genteel's painless blood collection equipment was born. It creates a vacuum in the blood collection site, produces vibration, and then penetrates at an extremely fast rate, almost painless.
Thanks to Princeton's laser blood glucose meter, piercing blood collection may be eliminated in the future. The device uses mid-infrared light that penetrates into the body's cells and is absorbed by the sugar in the blood. By measuring the amount of light absorbed, an individual's blood glucose level can be estimated. The tester simply places the palm of the hand on the laser beam source and reads on the display.
In addition, the Israeli company Beta-O2 has developed a bioartificial pancreas and conducted clinical tests at the Uppsala University Hospital in Sweden. Known as ?Air, this device is basically a bioreactor consisting of islets and devices that produce insulin and glucagon, working like a healthy pancreas.
Before the emergence of a reliable bioartificial pancreas, we already have products that mimic the function of the pancreas to some extent, for example, the FDA (United States Food and Drug Administration) approved Animas Vibe insulin pump and the Dexcom G4 PLATINUM blood glucose monitor. Both devices ensure blood sugar levels are within control.
Radiography equipment
The Utrecht University Medical Center in the Netherlands is building a laboratory that will introduce two devices: the Elekta linear accelerator and the 1.5 Tesla MRI magnetic resonance imager. The combination of these two devices is unprecedented, and since imaging and treatment can be performed simultaneously, it is hoped that more accurate tumor treatment will be provided.
In addition, General Electric (GE) also introduced 3.0 T MRI, which can shorten the imaging time by 2/3. The new device also features GE's latest SilentScan, which will make the device quieter at work. Siemens also demonstrated the new SOMATOM Definition Edge CT scanner for dual energy imaging using a single source X-ray tube.
If you are about to do a CT scan, there is good news: no additional testing is required, a CT scan can provide bone density values, and MindwaysCT software can determine your bone density by abdominal or pelvic scans or even colonoscopy. value.
Drone ambulance
When a severe arrhythmia patient develops a disease, the defibrillator is usually the only device that can stop death. But in many places, automatic external defibrillators (AEDs) are rare, and patients are given only a few minutes.
So, a student at TU Delft University in the Netherlands developed a flying drone equipped with a defibrillator. Emergency personnel can control the drone and fly to the disease scene as soon as possible. Currently, the drone is still in the prototype stage.
The world's smallest pacemaker Micra
In November 2014, Medtronic released the world's smallest pacemaker Micra. Unlike traditional pacemakers that are implanted by the shoulder or chest, the Micra enters the heart from the blood vessels of the legs and is attached to the heart muscle in a minimally invasive manner with minimal risk of infection.
Due to its small size (only 1/6 of the traditional pacemaker), the implant is convenient, and the researchers hope to improve the surgical results while reducing the difficulty of surgery.
In short, in the field of medical technology, the past 2014 is an exciting year.
