Flexible Circuitry Growth in Medical Electronics

!±8± Flexible Circuitry Growth in Medical Electronics

The medical electronics industry is one of the fastest growing markets in the United States. As the drive to reduce space and weight while adding functionality at a reduced cost continues, flexible circuitry is fast becoming an ideal interconnection and packaging design solution for this industry.

The adoption of flexible circuitry in medical devices goes back to the early 1970's, when companies like Cardiac Pacemakers and Medtronic used flex circuitry for implantable pacemakers and implantable defibrillators. As electronics and packaging advanced, medical products have enjoyed a tremendous growth both in the US and overseas. This growth can be expected to continue as new and innovative products, with increasingly demanding electronic requirements, challenge product designers to get ten pounds into a five pound bag.

Today flexible circuits are found in a vast assortment of medical applications:

Implantable Medical Devices. These include pacemakers, defibrillators, neurological implants and cochlear implants (hearing). These devices are surgically implanted in the human body. Product requirements are extreme reliability, long lasting, light weight, and compact in size. Non implantable Medical Devices. Hearing aids, drug dispensing systems, and external defibrillators (attached to patient) are some examples of this medical application. These devices are usually worn or attached to the skin of the patient. Monitoring Devices: Devices include portable or wearable electronic devices that monitor heart rate, blood pressure, body temperature, and blood sugar rate. Also included in this category are bedside monitoring devices. Diagnostic Equipment: This category includes equipment that does ultrasound scanning, MRI's, CT scanning, X-Ray's and a variety of other types of equipment that aid in detecting and diagnosing health problems. Surgery Tools: These include electronic saws, screw drivers and cauterizing scissors for clamping and closing blood vessels while performing surgery. Single Use Devices (SUD's). Applications include ultrasonic scalpels, electrode recording catheters, biopsy instruments, electric biopsy forceps and hundreds of other applications where sterile requirements dictate one time use.

The variety of uses and applications is continually expanding with innovative new designs or redesigns of existing equipment. This makes the medical industry one of the fastest growing and existing segments for flexible circuit applications. There are a number of important reasons that flexible circuitry is ideal for the medical industry:

Reliability: As early as the 1950's, flexible circuitry was used in the military and avionics industry, with both applications requiring extraordinary reliability. The nearly 20 years of proven performance in these high demand applications provided the medical industry with confidence in flex circuitry's reliability and robustness. Flexible circuitry has inherent advantages because it eliminates connection points, thereby simplifying assembly and eliminating chances of human error or interconnect defects such as poor solder joints.

Space and weight: The demand in the medical industry to make devices smaller and lighter makes flexible circuits ideal in applications when weight and space are a premium. Flexible circuitry is thin (total circuit thickness can be Bio-compatibility: The materials used in flexible circuits have proven to be bio-compatible in a wide range of applications. While implantable devices are fully sealed to eliminate contamination, non- implantable devices are used in applications requiring contact with human skin.

Feature Density: Flexible circuits can be built with narrow lines and spaces (conductor trace and space widths less than .005" are quite common) and are constructed with multiple layers. This becomes increasingly important as designers are continuing to reduce volume while increasing functions.

Dynamic Flexing: Flexible circuitry has outstanding ability for dynamic bending or movement. This includes applications such as providing interconnection through a hinged device or maintaining connection through devices that expand, contract or telescope during use. Material construction and circuit layout are particularly important in dynamic flex applications. Consulting with a flex vendor or other industry expert is recommended when moving parts need to be connected.

Cost: Since flexible circuits reduce the number of connections required, they can simplify and reduce assembly costs and are manufactured efficiently in high volume. Eliminating connectors, soldered wires, and rigid printed circuits are possibilities that further reduce overall cost in an interconnection design.

Supply Chain: The materials used to make flex are widely available. There are several suppliers of flexible circuitry with knowledge and experience in medical applications. A review of supplier capabilities based on the requirements of an individual application is recommended.

Technical Support: There is a plethora of technical resources available for application and design support in the USA, including capable and experienced support from many flex circuit suppliers. Organizations such as IPC have helped support the cross fertilization of technology and knowledge across the country. The wide variety of applications of flex in electronics has created a wealth of experience and innovation in this industry that can be passed on to medical applications.

The demand for flexible circuitry in the medical industry will remain robust as electronic medical equipment continues as one of the hottest growth areas for the electronics industry. The aging population, longer life expectancy, demands for more affordable and less invasive health care, and the continued advancement in technology are some of the factors driving growth in this market segment. Increasing possibilities for the use of flexible circuitry in medical electronics will certainly continue as designers identify additional ways to take advantage of the opportunities offered by this 3 dimensional interconnection technology.

AEDs: More Effective and Easier to Learn Than CPR

!±8± AEDs: More Effective and Easier to Learn Than CPR

For decades, if someone's heart stops beating, CPR was the standard form and most effective first aid. CPR is taught in classrooms and community centers around the world, led largely by the American Red Cross urges all Americans to help in the methods and techniques to give CPR certified. However, new technologies and more convenient is now considered by many to be easier and more effective CPR. An automated external defibrillator, which is often consideredAED, may be a far more powerful tool for saving lives. Impressively, defibrillation via an AED is far easier to perform than CPR, even for someone without any training.

AEDs are lightweight, portable devices that can jumpstart a victim's heart by using an electrical pulse called a biphasic shock. Guiding the rescuer with a combination of simple and clear voice, text and graphical instructions, AEDs do nearly all of the work, enabling practically anyone save a life!

As opposed to CPR, which can easily be done incorrectly, too slowly, or too shallow of compressions so that the heart is left unaffected by the efforts and will not restart on its own, an AED is easy to use and can actually restart the heart with just the push of a button. Using the same technology found in emergency rooms, operating rooms, and doctor's offices all over the world, an AED can not only help an individual suffering from cardiac arrest until professional medical help arrives, it can literally save their life. Phillips, Zoll, Heartsine and other companies manufacture very portable defibrillators that are surprisingly affordable, and refurbished models are often available for under ,000, according to AED resource Web site Start A Heart/>.

Generally speaking, performing CPR is a great deal more complex than one may believe. Training and refresher classes are incredibly important to ensure that you not only perform the motions of CPR in the correct method and speed, but also know the appropriate times to perform CPR. Many AEDs however, use sophisticated software and simple voice commands to analyze a patient and instruct the operator on how to restart a heart. These AED devices are found in airports, schools, public spaces, and private homes all across the country, providing an advanced option in case an emergency requires resuscitation.

Many individuals do not have the strength or stamina to properly perform CPR, since the activity takes a great deal of energy to correctly perform in order to receive the best results. Furthermore, you may need to perform CPR for an extended amount of time depending on where the victim is currently located and how easily accessible they are by emergency medical staff. In contrast, individuals of all strengths can use the AED device, since it requires the individual merely to push a button in order to jolt the heart back to life using a shocking stimulation. Generally speaking, it only takes one or possibly two shocks to the heart in order for the victim's heart to properly respond, allowing the individual working the defibrillator to perform other medical tasks that my be necessary.

As they become increasingly common, you will find an AED in nearly every public place. However, you should still ensure you know the proper methods associated with CPR in case you need to assist someone and are unable to access an AED.

Automated external defibrillators - The history and the invention of antiepileptic drugs

!±8± Automated external defibrillators - The history and the invention of antiepileptic drugs

The discovery that someone's heart can be restarted with the use of an electric charge is one of the greatest developments in modern medicine. This idea began around 1888 when William Mac suggested that ventricular fibrillation can cause sudden death. In 1989, Prevost and Batelli made the discovery that large amounts of voltage supplied to the cardiac ventricular fibrillation in animals could stop. Other studies funded by the nineteenth century, scientists have concludedCurrent effects on the heart.

An AED (Automated External Defibrillator) is a portable electronic device that is able to determine someone's heart rhythm. Detect life threatening problems within the heart and has the ability to treat them with defibrillation. If necessary, an AED can deliver an electric shock to the heart to restore a normal heart rhythm. When someone suffers a sudden cardiac arrest, the probability of survival he or she reduced 7-10 percentevery minute that passes without CPR or defibrillation or.

The first successful defibrillation of a human being was reported in 1947 by Dr. Claude Beck. During one of his operations, he realized his patients experienced ventricular fibrillation. He runs an AC of 60 Hz and stabilize the heartbeat. This particular patient was in his life, the defibrillators have been created.

An AED is equipped with a computer which evaluates heart rhythm, determines if it needsDefibrillation, and then manages the necessary degree of shock. The user of the AED is performed through this process with voice prompts, visual or both calls. Automated external defibrillators are usually in kits, power supply, electrodes including paddles and accessories sold. Each piece is made individually and then together with an integrated process. Today, manufacturers of medical devices, many defibrillators, external and internal, that created the situation for yearsthe lives of many patients.

External defibrillators used in hospitals and emergency sites. The user begins by turning on the defibrillator, and applying conductive gel to the patient's chest electrodes or paddle. The energy level is then chosen and the allegations of the device. The blades are mounted firmly on the chest with a slight pressure. To find the buttons at the electrodes are pressed together and then electric shock administered to the patient. After this procedure, theThe heart rate is then monitored for a regular heart rhythm. The entire process is repeated, if necessary.

In 1954 the first closed chest defibrillation in a dog Kouwenhoven and William Milnor was performed. This process was developed by Paul Zoll in 1956, studied the first success of a man. Qilliam Bennett Kouwenhoven was born in Brooklyn in 1886, was an electrical engineer, invented and developed, and three defibrillator and CPR techniques.

L '(AED Automated ExternalDefibrillator) was created 1978 Each unit is equipped with sensors that are placed on the chest to decide is, ventricular fibrillation occurs done. If it is established, the device provides the correct instructions for the supply of electric shock. These automated devices have the training that is necessary is to use defibrillators to reduce and also saved thousands of lives.

Sudden death from cardiac arrest - All the facts and a few who do not want you

!±8± Sudden death from cardiac arrest - All the facts and a few who do not want you

Among the many diseases afflicting humanity, the SCA is one of the most insidious. Basically it is the sudden, unexpected cessation of all regular cardiac activity. As stated below, is to offer a little 'more - but this is a good, functional definition of the moment.

The problem

Sudden cardiac arrest or SCA, although more common in older people is not limited to a specific age group. Children, athletes, people in the prime of life, almost allSCA can experience. The reason is that there are a number of different triggers. One of the most common is the regular heart attack, in which one or both are blocked coronary arteries by fatty deposits and plaque, resulting in reduced blood flow to the heart muscle. In fact, sudden cardiac arrest is often preceded by one or more heart attacks. Other triggers are: congestive heart disease, sudden, severe effects on the breast, and congenital (presentat birth) heart defects.

Survival rates for sudden cardiac arrest are quite bleak. Less than five percent of people suffer cardiac arrest outside a medical institution to survive. This is due to the fact that a person is only about five 56 minutes to get medical care before the start of the brain and body to receive the death. The time frame is painfully short, because of what happens to the heart during sudden cardiac arrest.

Unlike a heart attack inWith a sudden cardiac arrest, an electrical disturbance in the lower chambers of the heart, making it "flicker" to. Fibrillation is a condition in which the heart stops beating, but go to a chaotic motion shaking. Since this is in the lower chambers of the heart, the ventricle is known as, is known as ventricular fibrillation. At this point the body and the brain receives more oxygen and when the heart beats normally again in a few minutes,Damage to the brain, then follow the death of the body.

Approximately 250,000 deaths each year in the U.S. due to a sudden cardiac arrest. What can we do? Well, firstly, knowledge of CPR (cardiopulmonary resuscitation), ideal for all users have the clock - especially those of us with people who have heart disease are known and are living with high risk of heart problems. This can be used on a victim of sudden cardiac arrest, but it is a disease of success.

What canReady?

The ideal solution would be a defibrillator in the vicinity of the victim have the time of crisis. But for home use, portable defibrillators are underutilized today, especially because the public is not aware of how it should be. This is the same unit of general practitioners use on victims of sudden cardiac arrest when they reach the scene. Unfortunately, due to the small widow opened the possibility to save the life of the person, these attempts often arrive too late.

Automated ExternalDefibrillators are not new, but in its current form (from about the mid-90s) to a new device and truly revolutionary. I've seen only once in the hands of trained professionals, can now be purchased for less than the cost of a night at the local hospital (OK, I know, so a trip to the Bahamas or a Ming vase 100 years - well because I have little 'more specific). You can choose one for less than $ 1,500, maybe even a thousand, if you are willinglook around.

You are able to speak a non-trained rescuers through the entire process of defibrillation - and after noting, even if defibrillation is necessary. Some units will not even talk the rescuer through the CPR, if necessary.

What does this mean for the people most at risk?

It means "come" Do not worry about the paramedics too late to care. "These devices are portable. When they go to dinner or the movies as they can take. If the worst happensthey can rest easier knowing that survival rates increase from 5% to about 75% if defibrillation is administered within a few minutes after the onset of sudden cardiac arrest.

Sudden cardiac arrest has been tamed by the introduction of this new generation of defibrillators. What we need now is more public awareness and education. And we need more portable defibrillators in homes (where 80% of the victims are, in case of strikes SCA) and branches to be seen throughout the county.

We also need to seePortable defibrillators in schools, colleges and universities. It is not uncommon for young athletes or college students suffer a cardiac arrest and dying to hear, because medical personnel could not reach the scene in time.

What to expect

Happen because some of the above positive, we see a day, the mortality rate from sudden cardiac arrest begins a dramatic decline. But we hope to happen as soon as possible.
Spread the word, is not it?

And on thisNote:

if you want to increase awareness of this issue, copy, improve and e-mail this product to the local Congress or the Congress - no one really know who will benefit from the information.

Keep track of the Heart - a monitor-defibrillator

!±8± Keep track of the Heart - a monitor-defibrillator

A defibrillator-monitor is an important part of equipment for hospitals and EMS response for a patient from sudden cardiac arrest. The monitor can pursue medicine, the heartbeat of a patient to help diagnose and properly treat the problem. Include portable defibrillators more available to non-medical staff, can not be monitored because they are designed to be easy to use and have automatic electrical impulses.

Sudden cardiac arrest is one of theleading causes of death in the United States. Approximately 200,000 people die each year from the disease. Cardiac arrest occurs when the heart rate is unusually high in the heart ceases to pump blood efficiently through the body. The symptoms of sudden cardiac arrest is a sudden loss of consciousness and an interruption of normal breathing.

Cardiac arrest can strike anyone, regardless of their age. Many people know the news stories of young athletes from sudden collapseCardiac arrest during a game. These stories remind us that heart disease can occur at any age.

Although many people die each year from cardiac arrest, studies show that up to 50,000 people could be saved each year if defibrillation occurred the first few minutes of cardiac arrest. This has led many schools, businesses and public places to buy portable defibrillators. All hospitals and other first responders and defibrillators on hand.

DefibrillatorThe monitors are used on professional equipment for doctors and nurses treat a patient. The monitors record the heartbeat of the patient, store and transmit such information, and in the past, information on the model of the patient's heart rate to recover. The monitor and defibrillator are often combined in the same unit, making it easy where he wore.

While an untrained person would not need or understand the information on a monitor-defibrillator contain informationvery useful for medical professionals. It allows them to improve treatment and care of people affected by sudden cardiac arrest. Since time is of crucial importance, this situation is able to monitor the heart rhythm, and appropriate treatment is of utmost importance.

A defibrillator-monitor is contained in many professional models. Mobile devices are not for the general public typically include a monitor as most people would not understand thatThe information given. If you are looking for a hospital or other First Responder purchase situation, you might want a defibrillator with monitor for monitoring and data storage to acquire skills.

Defibrillators - An overview

!±8± Defibrillators - An overview

As defibrillators?

A defibrillator is a medical device for irregular heartbeat patterns, or how to correct heart rhythm disturbances known. Heart rhythm disorders are characterized by abnormal electrical activity in cardiac causes, characterized by irregular contractions. Many cardiac arrhythmias are common and often benign, usually described as feeling your heart beat faster. Other rhythm disturbances can interfere with the normal flow of blood, however, losing the vital organs like the brainOxygen and suffocate. Untreated, these arrhythmias may be fatal in a very short time. Defibrillators are used most commonly for the treatment of two types of very dangerous heart rhythm disorders. "V-tach" ventricular fibrillation or 'V-Fib,' and ventricular tachycardia or

Today, defibrillators, portable devices can be brought in ambulances, automated units placed in a public space, or even an implantable device inserted directly into a patient's body. No matter the style of the defibrillator, whichTreatment remains the same. The use of a fast, high voltage, charge current to the patient's chest, can interfere with a defibrillator for unusual rhythms and ready to resume normal heart rhythm. Despite the power of a supply shock that defibrillator, technological advances have lower energy shocks, which will be much less likely to create internal injuries and burns.

What are the risks of using a defibrillator is connected?

Although defibrillators can saveLife can be misunderstood defibrillators cause much damage and even death. Studies have shown that defective Sprint Fidelis leads from Medtronic implantable defibrillator in are prone to fracture, so as to release the unit to strong shocks at random. These shocks can be severe pain, fear and even death for people with implanted devices cause.

If you or a loved one is with a Medtronic defibrillator leads have been implanted with Sprint Fidelis leads, contact a lawyer immediatelyto discuss legal options. An experienced lawyer will be able to assess your case and provide legal assistance will be necessary to explore the complex litigation process.
