Thousands of people with heart disease can be saved by this invention

Australian scientists have invented a new device, which can help transfer energy to pacemakers without the need for a charging cable.

This device promises to help save thousands of people with cardiovascular disease.

If one day your heart suddenly becomes severely weakened, it needs to be used immediately with a mechanical pacemaker (VAD) . But to use this device, you must always have a nearby power source to plug the charger cable into.

Fortunately, people with cardiovascular disease will not need to worry about this inconvenience. Recently, Australian scientists have invented a wireless battery. It can energize VAD devices without charging cables.

In addition, the use of this new battery will reduce the body's ability to become infected by using older batteries.

Fully named 'ventricular assist device' , a device that supports the heart for patients, VAD is used when the patient's heart is unable to perform normal pumping functions, or completely loses the pumping function. .

Usually, the doctor will let the patient use the VAD device before a heart transplant, or during the recovery process from the surgery.

Cardiac devices play a very important role in the treatment of cardiovascular diseases, which can help save thousands of patients' lives. However, there are also force majeure cases where patients cannot use them.

'According to statistics from the US National Institutes of Health, more than 100,000 people are using VAD as an integral part of the body' , Mahinda Vilathgamuwa - medical expert of Queenland University of Technology (QUT) for know.

Vilathgamuwa also added: "However, with many potential risks, there are relatively few implantable devices to be transplanted into patients. And many patients have left because they cannot use this device."

The biggest risk of using VAD devices is that the patient is likely to become infected at the point of the charging cable to the inside of the body.

'Many deaths have occurred due to infection from the charging cable of VAD. Previously, to use them, users had to plug the charger cable into a nearby power source. VAD is attached in the patient's heart and will be energized through the cable beneath the skin. This cable is powered by an external battery , ' Vilathgamuwa said.

Around the human body is covered by countless bacteria and pathogenic microorganisms. We are still healthy thanks to the skin that has successfully completed the task of preventing other infectious agents.

However, the appearance of a hole in the protective skin layer causes harmful bacteria and microorganisms to have favorable conditions to invade, causing the body to become infected.

So the researchers invented a battery without plugging in the power cord, which can power the VAD without using a charging cable.

On the outside of the body, the patient will be equipped with a transceiver and a small portable battery.

"The system we are developing includes a lightweight copper coil. It can be transplanted inside the body to energize the pacemakers," Vilathgamuwa said.

On the outside of the body, the patient will be equipped with a transceiver and a small portable battery; This battery can be stored in a coat pocket or leather case. Inside, they will be fitted with an energy receiver. With such operation mechanism, VAD will not need charging cable to operate anymore.

"The system we are developing will completely replace the charging cable. According to statistics from recent tests, the system has reached 94% efficiency when powering VADs, without causing any What is the effect on the skin compared to the use of charging cables , " said Prasad Jayathurathnage, a QUT expert.

"We will conduct more laboratory tests, and will introduce a new frequency adjustment system to improve the performance of cardiac pacemakers."

These are just the first steps of this study, let's wait and see how far it will go.
