Robots help patients with heart failure through critical attacks

The new experimental robot model from scientists at MIT (USA) hopes to provide a better chance of survival for patients with heart failure.

Scientists at the Massachusetts Institute of Technology (MIT) have released experimental robots that give new hope to patients with heart failure or heart failure , so they can overcome the danger in school. Not enough blood to feed the heart.

This robot can assist patients with heart failure or heart failure.

According to ZDNet, this robot model is responsible for covering the heart and pumping blood in case patients experience heart failure symptoms. The section of the robot is shaped like a human heart tissue.

When wrapped around the heart, the robot uses compressed air to act on artificial muscles made of silicon. These muscles continue to compress and twist directly to the heart, thereby stimulating the heart to pump blood back without interacting with the fluid.

Researchers can now adjust the robot to create twisting and compressing forces in the heart in sync with the beat of a normal heart, but this also depends a lot on the needs of the patient.

Structure of ventricular support device.

It is estimated that heart failure affects about 41 million people worldwide and about 5 million people in the US alone. When the heart becomes exhausted after a long period of overuse or due to aging, the best way for this disease is artificial heart transplant.

However, it is not always possible to have a suitable source of organs and when there is not everyone has enough money to transplant. At this time, many people depend on ventricular support devices (VAD) , a type of device that helps prolong the heart's activity . But VAD cannot replace the function of the heart and they require patients to take anticoagulants and infections for the rest of their lives.

Unlike the VAD, MIT researchers' robot models are especially inaccessible to the blood of patients, so the patient almost does not need blood thinners or anticoagulants when used. Besides, the applicability of this robot model is very high for many problems related to the current cardiovascular intervention devices.

Robots have been successfully tested on pigs.

So far, robots have been successfully tested on pigs. Researchers injected drugs to stop the heart's heart from beating and, through tests, showed that the robot still responds to pumping enough blood to the pig's heart while the heart stops beating.

However, there are still certain limitations on the experimental robot model. Under the influence of torsion and compression, inflammation has occurred on the heart. Despite this, researchers have reduced the friction for robots by using hydrogels to create a protective layer between the wrap and the heart.

Hopefully in the near future, people will soon enjoy the fruits of this advanced medical technology.
