Unique scientific inventions

Used for many different purposes, the unique scientific inventions below are contributing to changing our lives.

Travel in the human body

Endoscopic examination of human organs with a camera hidden in a nasopharynx usually causes pain for the patient, and for some organs such as the small intestine, this classic method will not be performed. Recently, scientists have successfully built PillCam - tiny camera - only 26cm long and 11cm wide. This is the smallest camera, including a light bulb and a signal transmitting chip. PillCam not only captures clear images, but also has many valuable functions to serve medicine. For example, images of the small intestine have been difficult to perform because the small intestine is about 6m long and is located between the stomach and the large intestine. With PillCam applied through endoscopic methods from now on without pain, doctors have been able to identify the disease quickly and easily.

Firefighter

With a weight of 300 kg, the firefighter can step forward and backward for 4 steps and turn left and right. It is also possible to step over obstacles and climb stairs.

Carrying 3 cameras, this robot can observe the conditions on the ground and in the surrounding area, and send information to the operator. The robot is also equipped with two sensors with ultrasonic waves to withstand fire. The sensor will help the robot avoid obstacles and move to a safe place. A particularly useful feature for firefighters is that they can check and identify toxic substances, hypoxia and explosions.

Air conditioning kills avian influenza virus

In early 2006, LG Electronics Electronics launched the anti-H5N1 air conditioner, Anti-AI Aircon, with a special filter coated with leuconostoc citreum extracted from kimchi. 'Experiment

showed that the membrane is capable of neutralizing up to 99% of H5N1 virus in the air in just 30 minutes '- Seo Seok-jang, head of LG Electronics' Air Conditioning Research Laboratory, said.

In addition to special filters, Anti-AI Aircon is also equipped with effective filter layers with natural germicidal agents extracted from fish lettuce plants. In particular, the nano-ion membrane filter can remove dangerous chemical compounds such as formaldehyde and volatile organic compounds (VOCs). In addition, there are Plasma membranes that use high voltage to thoroughly remove micro-micro-impurities in the air. At ambient temperatures, the H5N1 virus can live up to 14 days in the air or in small dust particles.

The world's smallest artificial heart-lung machine

With size 20x30 cm (CAND image) , tiny MECC cardiopulmonary and pulmonary machine (Minimal Extracorporal Circulation) is a successful invention of a group of engineers and doctors at the University Hospital of Regensburg. MECC is able to save victims as soon as they are taken to an ambulance helicopter to be taken to the hospital. Mathias Arlt, of the University of Regensburg, said: 'Usually heart-lung machines are nearly 1.5m tall and weigh about 200kg. Although these machines are very effective in rescuing victims in danger because the heart and lungs stop working, but too bulky, it is not convenient to move in emergency flights. Meanwhile, our MECC machine only weighs 10 kg, so it is very convenient for the staff of the rescue team to bring along, when carrying out the rescue work . Just recently, MECC machine has proved its position. Very effective in the case of a female patient with cerebral hemorrhage, must be transferred by helicopter from a small clinic to Regensburg University Hospital for treatment. If it is not immediately transferred, the patient's condition is difficult to escape, and even if there is no assistance from the MECC and if traveling with a regular emergency vehicle, it will not be timely. Currently, patients are resting at home and on good recovery . ".

The MECC is currently only being used in Regensburg for bypass surgeries and according to experts' disclosure, another advantage of the MECC is that the amount of blood that must be transmitted to the patient is reduced and the Postoperative complications are also less frequent, compared to other artificial heart-lung machines.
