EMBEDDED SYSTEMS IN BIONICS
[attachment=27933]
The Human Heart
Heart has four chambers
Right chambers pump blood to lungs to receive oxygen
Left chambers pump oxygenated blood from lungs to rest of the body
Right and left atria receive blood
Right and left ventricles pump blood
Valves produce one-way blood flow from atria ventricles arteries
Energy to pump blood comes from nutrients and oxygen in blood
The Need for a Heart Substitute
100,000 Persons/year suffering from severe heart disease need new hearts
Only 2,000 patients receive heart transplants
Conclusion: many patients die waiting for a new heart!
Criteria for a Heart Substitute
Must fit into chest cavity and connect to atria, pulmonary artery and aorta quickly
Provide an adequate blood flow (8 – 10 liters/min)
Send deoxygenated blood to the lungs and oxygenated blood to the body
Operate continuously for an indefinite period of time
Provide adequate warning if something is wrong or if it is going to fail
BIONIC HEART
Artificial development of the heart started around 1950’s
When both the left and right ventricles of your heart are damaged, only a donor heart transplantation, or a replacement heart can save your life.
The AbioCor Implantable Replacement Heart is designed for patients whose hearts have suffered irreparable damage to both ventricles.
The AbioCor® Heart
Implantation of this Abiocor heart is done in the year 2001 in Louiswille
Patient is able to walk around, organs are functioning normally, undergoing daily rehabilitation for eventual release
How the AbioCor® Heart Works
Hydraulic pump forces blood to lungs and body
Power is provided by an internal rechargeable battery
Battery is recharged by coils on surface and below skin
Internal controller monitors system and controls pump speed
AbioCor® Design Criteria
Grapefruit size, weighs 2 lbs, requires a 7 hour surgery for implantation
Can provide up to 8 liters/min of blood to the lungs and body
Has two chambers for pumping deoxygenated blood to the lungs and oxygenated blood to the body
Wireless energy transfer system allows for continuous operation
Internal controller monitors operation
AbioCor® Design Criteria
Internal controller increases/decreases blood flow based on blood oxygen levels
Materials are inert to the immune system
Completely contained within the chest – no wires or tubing through skin!
Made of special materials and special pump design to prevent clots and RBC damage
Pumping alternates between chambers, creating a pulsatile blood flow
ADVANTAGES:
Bionics help the disabled and the ailing in a great way.
By embedding this device in the worn out part ,the other parts of the body does not get affected by this device.
DISADVANTAGE:
Cost is very high so that some of the people cannot have its utilization.
CONCLUSION
As India is a developing country. This development is mainly due to the application of electronic devices in any areas. This bionics is also a part of the electronic implantation which results in a great development of the country.
This technology is available to us in present days. If once heart beat stops the man is completely died, but this bionics has the capacity to replace that heart. But the only problem is the cost
