6 inventions that could save your life
Edition Inhabitat usually talks about the technologies that they think they can save the world. However, many scientists, engineers, computer geniuses and designers around the world are engaged not only in global issues of saving the planet, but also more mundane, that is, in other words, they are trying to make us healthier, and our life easier. Here are six designs that Inhabitat believes have a chance to save our lives someday.
1. A bleeding syringe
If someone gets a bullet wound, quick and effective medical care becomes a matter of life and death. XStat Syringe can stop arterial bleeding in just 15-20 seconds. The sponges that enter the wound expand rapidly and stop the blood.
This syringe was developed by Revmedx in conjunction with physicians from the US Special Forces. They plan to expand the application of technology to other types of wounds.
The development of a syringe for military purposes began. On the battlefield, difficulties caused injuries in an area in which a wound cannot be pressed, for example, the sacrum and armpits. There were no special remedies to stop the bleeding in these areas, and Revmedxtackled the problem. The technology is based on the use of small sponges that are inserted into the wound using an applicator with a diameter of 30 or 120 mm, similar to a syringe. When contacted with blood, these sponges expand, stop bleeding for 20 seconds and press wounds. Each sponge has a mark that is distinguishable by x-rays. They plan to use the same technology for use in other types of wounds.
The XStat takes about 4 hours, which gives enough time to transport the victim and prepare for the operation. In XStat has its drawbacks: it can not be applied to the chest, the abdomen, the collarbone, and others.
Diabetes is a disease that affects every nineteen people on the planet. Therefore, developers of various kinds of innovations cannot ignore this problem. Patients have to constantly monitor the level of sugar in the blood, which implies unpleasant procedures that have to be carried out regularly. Here are a couple of promising developments to make this process easier.
2. Google 's health lenses
Google is developing contact lenses that track blood glucose levels. In the future it is planned to teach them to warn their owner when the sugar level rises or falls below the permissible limit.
A miniature sensor and a tiny wireless chip that respond to changes in blood sugar levels are built into the lens.
Sugar levels can be measured by tears, which is what Google noticed . Built-in sensors and chips are located between the two layers of the lens itself. LED indicators, also built into the lens, will flash when the sugar level reaches a dangerous point. The lens prototype, which was actively developed back in January 2014, was supposed to record blood sugar once a second.
In addition to the lens itself, it was planned to develop an application that would simultaneously report the level of sugar and the diabetic wearing the lens and his doctor.
3. Tattoos with nanoparticles
People with diabetes have to regularly pierce their fingers, which is uncomfortable, unpleasant, and the method is not very accurate. An alternative was found at MIT : a tattoo can monitor glucose levels. Specially designed ink can be tattooed, and the bracelet will report troubles.
MITis developing a device that could just be worn on itself. Its action is based on the use of carbon nanotubes, which are not destroyed by the action of daylight, wrapped in a polymer sensitive to sugar vibrations. When interacting with glucose, the sensor will glow, which can be detected by the emission of near-infrared waves. Nanotubes should be part of the ink, and infrared radiation aimed at the tattoo will provide a wristband that looks like a wristwatch. A tattoo will require renewal approximately every six months. And, of course, careful checks of the correct operation of this device are required, so development can take many years.
4. Ambulance drones
A medical drone can fly to help in one minute and thereby save someone's life. With him, he can carry a first-aid kit, defibrillator or device for cardiopulmonary resuscitation, and is also equipped with a camera that allows medical staff to direct the actions of eyewitnesses.
The drone is free from troubles that may lie in wait for an ambulance on its way to the victim. Its coverage is 12 km 2. The author of the project, Alec Momont, hopes to significantly reduce the number of deaths that occur due to the fact that the ambulance does not have time for the patient. The carrying capacity of the drone is about four kilograms, which allows you to deliver the necessary medical device to the scene. People will be able to call an ambulance as usual, and in a minute a drone will fly to them not only with a first-aid kit, but also with a camera that allows the operator to monitor the situation and tell people in the vicinity how to help the victim while waiting for an ambulance.
5. New generation pacemaker
Current pacemakers are far from perfect, but the new technology developed by Urbana-Champaign in Illinois could change the future of life-saving devices. The development team has created a thin membrane pierced by sensors and electrodes. This pacemaker will fit the size of each particular heart and support its work.
After the stages that used high-resolution visualization and computer simulation, a heart model was created on a 3D printer, on which the membrane was first tested. Then tests were carried out on the heart of a rabbit.
According to the developers, the pacemaker is similar to a pericardial bag and fits tightly around the heart. He will be able to constantly monitor the electrical activity of the heart, and if necessary, applying an electrical impulse to the desired area of the heart, stop arrhythmia and prevent heart attacks.
The developers say that work on a pacemaker can be completed in 10 to 15 years.
6. Organovo and 3D organs
Every day, an organ is transplanted to 79 people, and 18 people die every day, without waiting for their donor. Company Organovo , based in San Diego, to improve this situation, trying to develop a 3D-printing technology to create human organs. To date, they have managed to print a small liver. Organovo
CompanyIt is known for printed fabrics, which have already become widely available and have been recognized by scientists and researchers. The company's goal is to accelerate and reduce the cost of the research process of medicines. Tissues printed on a 3D printer allow you to directly observe how and how effectively and safely a particular drug is being treated, and, of course, these fabrics allow you to avoid discussing the question of how ethical experiments in this area are done on animals.
Now that the miniature liver has been created, the prospect of printing organs for transplantation has come a little closer.
