ISRO's rocket technology to help heart patients - lithium ion cell

Ocket science may not be able to repair the broken heart, but the technology at the Indian Space Research Organization will soon help patients who need a heart transplant.
The materials and mechanisms used on the Indian rocket have been adjusted by ISRO to make a device that some call a step in making a "artificial heart. 'The heart-
The test of auxiliary equipment was carried out on animals, and the results proved to be successful.
Known for its orbit satellites and flying giant rockets,
ISRO's excellent team developed this heart pump as a derivative technology in their spare time.
Cardiologists are very excited about this development because it provides life for terminal patients
Since the heart transplant, most patients still have no access.
ISRO scientists have perfected a device that helps the human heart pump blood, especially in the case of the left ventricle, and the most powerful part of the human heart begins to fail.
It is called "left heart assist device ".
This small electronic device can deliver 3 to 5 liters of blood per minute.
Kiran Kumar, ISRO chairman, said the rocket technology provides an alternative system that can deliver blood to seriously ill patients and can definitely save human lives.
Special pumps manufactured by the Indian space agency can also be powered using domestic high-energy density batteries lithium-ion batteries, which is also the first time another team of rocket scientists has made them again in India.
The pump weighs about 100 grams and can be installed inside or outside the body and needs to be connected to the battery to power it.
The device is made of a special titanium alloy, which is "biological"
K Sivan, director of the Vikram Sarabhai Space Center at Compatible uvananthapuram, said it is Compatible, where special heart pumps have been mastered.
The ocket scientists at the VSSC use titanium alloy to make rocket engines and satellite components, so they have a complete grasp of the metallurgy and manufacturing of materials.
The same material on the rocket engine has been transformed into a compact but high-tech pump.
"We have seen that the device satisfies all the creatures.
"Mechanical requirements and pumping requirements," said Sivan . ".
"This particular device was tested on six animals.
After testing for 6 hours, other organs of the animal were examined.
They are in good condition.
This is a great achievement.
"This is a successful device," added Sivan . ".
"There is no doubt that this is an important step for ISRO to finally develop the artificial heart.
"This device uses a common technique called a centrifugal pump to deliver blood.
The electronics and magnets used in micropumps are manufactured by engineers who make lightweight systems used on Indian satellites.
The design of the pump must be like this, it should not heat up even if it runs continuously, obviously it should be unqualified.
The device, similar to the artificial heart, has been tested on six pigs.
Sree Chitra Tirunal Institute of Medical Science and Technology from Thiruvananthapuram has operated on healthy pigs and has used this special pump developed by ISRO
The pig lived for a full six hours, and this is the whole design of the experiment.
When the blood was pumped by the device after bypassing the biological heart, no damage was reported to it.
Throughout the experiment, even other organs of the pig were not harmed.
Scientists at the Sree Chitra Tirunal Institute of Medical Science and Technology said, "this is still an ongoing work," and will be in animals before the device can be tried out in humans.
Patients in Ealthy India need a heart transplant, but no matching donors have imported the equipment, and some private hospitals are even in New Delhi, the all-India Institute of Medicine.
A cardiologist familiar with the technology says the cost of importing a heart pump device and then putting it in is more than rupees.
By contrast, scientists at the Vikram Sarabhai Space Center said the cost of the device they developed was only RS 125,000.
Rocket scientists say the cost difference is so big just because the Vikram Sarabhai Space Center already has expertise and materials, all they have to do is set up the right team of experts including metallurgical expert electronics engineers and fluid mechanics experts and designers working with cardiologists to come up with the right design.
In about 6 years, after a team of more than 20 experts completed many permutations and combinations, they came up with the right design.
"It's a complex device, and it's an exciting development," said Balram Bhargava, professor and executive director of cardiology at Stanford Indian Biodesign Center, International Institute of Biological design, A doctor at the All-India Medical Research Institute in New Delhi confirmed that as far as he knows, no one in India has designed a left-heart aid device on its own so far, he added, this is an important bridge waiting for heart transplant patients.
Professor Bhargava warned that the device can only be used in very special medical situations.
Interestingly, the Vikram Sarabhai Space Center has also recently developed a high-value lithium-ion battery that can now be used to power a heart pump.
India has been importing these lithium-ion batteries, but recently the transport minister Nitin Gadkari authorized ISRO to master the technology in order to use it for zero-pollution electric vehicles.
The Vikram Sarabhai Space Center will try to reduce these lithium-ion batteries and is expected to power the left-heart assist, Sivan said.
