‘The Most Sophisticated Items to Have For a Better Life’

Futuristic Material That Exist

Teflon is a company that manages cookware. It has been successfully producing Teflon non-stick coating that is been use worldwide. This coating make kitchen work much easier and ladies love it very much. The chefs use this as the opportunity to rise up their production. The question is about the level of PFOA for using such material expose to heat even when it has been use for more than 40 years without cause any health problems to the user. The coating is made from some kind of polymer that have many unique characteristic.

           The polymer has many unique properties, which make it valuable in scores of applications. It has a very high melting point, and is also stable at very low temperatures. It can be dissolved by nothing but hot fluorine gas or certain molten metals, so it is extremely resistant to corrosion. It is also very slick and slippery. This makes it an excellent material for coating machine parts which are subjected to heat, wear, and friction, for laboratory equipment which must resist corrosive chemicals, and as a coating for cookware and utensils.

 

          Let’s take a brief for what is Teflon really are. Teflon is the registered trade name of the highly useful plastic material polytetrafluoroethylene (PTFE). PTFE is one of a class of plastics known as fluoropolymers. A polymer is a compound formed by a chemical reaction which combines particles into groups of repeating large molecules. Many common synthetic fibers are polymers, such as polyester and nylon. PTFE is the polymerized form of tetrafluoroethylene.

Cross Section Of The Pan

PTFE is used to impart stain-resistance to fabrics, carpets, and wall coverings, and as weatherproofing on outdoor signs. PTIZE has low electrical conductivity, so it makes a good electrical insulator. It is used to insulate much data communication cable, and it is essential to the manufacture of semi-conductors. PTFE is also found in a variety of medical applications, such as in vascular grafts. A fiberglass fabric with PTFE coating serves to protect the roofs of airports and stadiums. PTFE can even be incorporated into fiber for weaving socks. The low friction of the PTFE makes the socks exceptionally smooth, protecting feet from blisters.

The device is also modular, allowing hospitals to customize the control package based on their needs.

LifePort Organ Transporter 2003

          The method of storing and transporting organs has traditionally involved placing an organ in a cooler filled with ice until the LifePort Organ Transporter came into the picture. The product uses mobile machine perfusion to improve transplant outcomes, allowing the use of more organs and lowering the number of organs discarded. The process involves pumping a cold solution through the organ to reduce tissue damage even while the organ is in transport. The LifePort started as a transporter for kidneys and has been so successful that the product is branching out into use for the heart, pancreas, liver, lung, and intestines.

Pinnacle TPN Management System 2007

In an improvement on patient safety, the Pinnacle system provides a safe and easy way to check, compound, and deliver total parenteral nutrition (TPN) to patients. The device controls intravenous formulations using amino acids, dextrose, electrolytes, and lipids for patients who rely on tube feeding or can't tolerate oral intake of food. The Pinnacle system streamlines the TPN process by combining automated compounding technology with a safety verification system and special software. The system can accurately measure and combine up to nine nutritional compounds and prepares one liter of TPN solution in less than one minute. Its safety-check software and bar coding ensure that solution is going to the correct patient.

Impella 2.5 Circulatory Support System 2008

The Impella 2.5 is a minimally invasive, percutaneous cardiac assist device that allows the heart muscle to rest and recover. Impella is designed to actively unload the left ventricle, reduce heart muscle workload and oxygen consumption, and increase cardiac output and coronary and end-organ perfusion. Impella received FDA 510(k) clearance in June 2008 and has been used to treat heart attack patients, patients undergoing high-risk angioplasty, peripartum cardiomyopathy, and viral myocarditis. It is ¹∕100 the size of the heart. The device is approved in more than 40 countries, has been used to treat more than 1700 patients worldwide, and has been the subject of more than 50 peer-reviewed publications. The device was the recipient of a 2007 Medical Design Excellence Award.

        Many key technologies got their start before MD&DI's inception and before current regulations. Here are a few that have made a significant contribution to the way medicine is practiced.

Medical Devices (Part 5)

CyberKnife Robotic Radiosurgery System (1999)

The CyberKnife is a miniature linear accelerator mounted to a robotic arm. It noninvasively delivers concentrated beams of radiation to a targeted tumor from multiple positions and angles. The tumor receives a cumulative dose of radiation high enough to control or kill the tumor cells while minimizing radiation exposure to surrounding healthy tissue. It delivers to almost all parts of the body, particularly for surgically complex tumors. In 1999, the device was approved for treatment of tumors in the head and base of skull. In 2001, FDA cleared enhancements to the CyberKnife System for tumors anywhere in the body.

da Vinci Surgical System (1999)

          The da Vinci surgical system has made it possible to treat a broader range of conditions with a minimally invasive approach. The system's microchip technology and 3-D optics enable surgeons to perform complex procedures by making tiny incisions. The da Vinci offers users greater precision, an increased range of motion, improved dexterity, and enhanced visibility. Because of the device, patients may experience less pain, less scarring, reduced risk of infection, and a faster recovery time. The surgical system has been used to treat heart conditions, prostate cancer, endometrial cancer, morbid obesity, and mitral valve regurgitation.

PillCam (2001)

Is your digestive tract ready for its close-up? The PillCam is a capsule that houses a miniature video camera, lights, a transmitter, and batteries. Once a patient swallows the pill and it passes through the digestive tract, it takes photos of the small intestine and sends them to a small recorder affixed to the patient's belt. This technology has helped patients avoid invasive and painful endoscopic diagnostic procedures just by swallowing a pill. It also allows the entire small bowel to be viewed (endoscopes allowed physicians to see only the upper part of the small bowel).

OraQuick Advance Rapid HIV-1/2 Antibody Test (2002)

Major progress has been made since the first AIDS-related diagnostic test was commercialized in 1988. In 2002, the OraQuick Advance Rapid HIV-1/2 Antibody Test became the first rapid HIV test to earn FDA approval. In clinical studies conducted by the manufacturer, OraSure Technologies Inc., the test correctly identified 99.6% of people who were infected with HIV-1 and 100% of people who were not infected with it. The test provides results for patients in about 20 minutes. This is key because with previous tests, which took several days to process, a significant number of patients never returned to the clinic to learn whether or not they were infected. The test can be stored at room temperature, requires no specialized equipment, and can be used in both laboratory and nontraditional clinical settings.

Digital Hearing Aid (1987) 

 

A digital hearing aid isn't automatically superior to analog devices. But starting with the creation of the Nicolet Phoenix the first digital hearing aid in 1987, the devices have become increasingly sophisticated. Much of this owes to digital signal processing technology, which has allowed manufacturers to enhance features and provide users with more comfort and higher-quality hearing. For example, digital hearing aids can drastically reduce feedback while the listener is wearing the device and enhance speech based on temporal or spectral content. The Lyric is the only extended wear hearing device on the market it can be worn continuously for up to 120 days.

Ventricular Assist Device (1992)

          A ventricular assist device (VAD) is a mechanical pump that helps a weak heart pump blood through the body. It is often called a “bridge to transplant” because it can help patients survive until they get a new heart. The BVS 5000, a biventricular assist system manufactured by Abiomed, was the first VAD to earn FDA approval. It has supported thousands of patients since entering the market. Most recently, VADs have evolved to provide long-term support to patients with congestive heart failure.

Medical Lasers (1995)

 Even now, many industry observers say that the surface has only been scratched with medical lasers and their potential. Medical lasers (light amplification by stimulated emission of radiation) use focused light sources to treat or remove tissue, and they are used for a variety of vision, dental, cosmetic, and general surgery procedures. One benefit for surgical procedures is less bleeding; heat from lasers cauterizes blood vessels, which leaves medical personnel with less blood to deal with compared with scalpels. Perhaps the most popular application is LASIK, a type of refractive laser eye surgery to correct myopia, hyperopia, and astigmatism. LASIK surgery has transformed outcomes for patients suffering from these conditions. FDA approved the first excimer laser in 1995.

LightCycler Real-Time PCR (1998)

Molecular diagnostics have paved the way toward individualized medicine. The technology enables point-of-care diagnoses for infectious diseases, meaning infected patients can be identified quickly, enabling immediate treatment and protection for those at risk. One of the best-known devices is the LightCycler Real-Time polymerase chain reaction (PCR) System from Roche Diagnostics. Using PCR, scientists can take a specimen containing a minute amount of genetic material, repeatedly copy a selected region from it, and within hours, generate a sample sufficient to perform a variety of tests. PCR is versatile. Many types of samples (e.g., blood, skin cells, saliva, hair) can be analyzed for nucleic acids. Any sample used for PCR must contain the DNA strand encompassing the region to be amplified.
