Quick and Inexpensive Diagnostic Sensor Can Detect Infectious Diseases

Whether they are working on a cure for life-threatening diseases or the common cold, inventors from the School of Medicine at Stanford University are working on an inexpensive medical sensor that would simplify the diagnosis of immune deficiencies. Their most recent development is a microfluidic waveguide sensor, which measure various strains of white blood cells by sorting and counting them within samples of blood and other bodily fluids. Known as a key component of the body’s immune system, white blood cells can be identified using a sensor that is no larger than a thumbnail, making it easy to diagnose common ailments in a doctor’s office, hospital nursery or even a disaster scene.

As medical equipment manufacturers are acutely aware, the cost of advanced diagnostic devices is not always within the reach for many healthcare institutions. However, the need for point-of-care monitoring of immune deficiencies and infectious diseases is paramount in a clinical setting. According to a team of inventors in the pediatrics department at Stanford University, the field of bio-microfluidics offers the best hope for screening immune-deficiencies without the need for costly medical equipment. Commercialization of such a sensor could revolutionize rural medicine and make it easier to treat patients in a timely and effective manner.

Initially developed for screening newborns with severe immunodeficiency and low T-cell counts, the 15-minute test can also screen older children and adults in the same way. While the sensor was not originally intended for widespread use, its low-cost mechanism makes it a natural diagnostic tool for a wide range of conditions.

The various types of white blood cells found in the body each have their own role in fighting diseases. Some are used on a daily basis to fight off common infections such as the common cold, and others are more inclined to battle cancer and AIDS. Until now, the process of counting cells required large blood samples and costly medical equipment that could only be used by trained lab technicians. Catching these immune disorders early is a key element in curing them, and this new sensor will make it as easy as using a glucometer for measuring blood sugar.

Micro-Robots May Be Used to Detect Diseases

As medical equipment manufacturers continue to utilize the latest technology, they are already working on the “next big thing” in micro-robotic medicine. In fact, the robot they are developing is so advanced that it functions very much like a living creature. Imagine a device where microelectronics and nature-inspired technology blend together to create something called “Cyberplasm.” While this may sound more like the 22nd century; a new breed of prototypical robots are being developed to act very much like living organisms, complete with electronic “nerves,” eye and nose sensors and artificial musculature propelled by an external energy source.

By integrating robot components, the intention is to create a device that responds to certain chemicals and light in the same way that a biological system would. Unlike traditional robot-like machines, these prototypes are a unique way to forward the study of robotics. The result of a partnership between the UK’s Engineering and Physical Sciences Council and the National Science Foundation, this project commenced in a “sandpit” that has been funded by the two organizations.

What is the goal of Cyberplasm?

Scientists believe that Cyberplasm will ultimately enable the detection of a wide range of diseases. The end result of the prototype is likely to be smaller than 1 millimeter long and may even be built using a Nano scale. Bioengineers from the team at Newcastle University compare this invention to collect an incredible amount of data from the human body; far more than what can be derived by current diagnostic tools.

Electronic impulses that are sent to the device will capture external stimuli and convert it into impulses, which are translated by the electronic brain using custom-designed microchips. In a similar fashion, data collected about the chemical make-up of the area surrounding the robot is stored within these systems for later interpretation by the robot’s operator.

Ultimately, Cyberplasm could represent the first step toward major advancements in prosthetics. Here, living muscle tissue could be reengineered to contract and release by exposure to electronic and light wave stimulation medical equipment. While the prototype of Cyberplasm is currently in the development stage, researchers expect to be in the assembly stage within a few years and ready for a clinical rollout within five years.

Future of Medical Equipment May Include Tiny Injectable Wireless Devices

Once a futuristic dream of medical researchers, a team of engineers at Stanford University have found a way to wirelessly propel a tiny medical device through the bloodstream. People who remember the 1966 movie “The Fantastic Voyage” will recall the fictional team of scientists that shrunk a submarine to a microscopic size and injected themselves into to the bloodstream of the human body. This device may not have any passengers aboard, but it does allow for wireless communication between a doctor and his diagnostic device.

New breakthroughs in medical equipment technology are happening so quickly that something as miraculous as an injectable diagnostic tool might seem insignificant, but this development is anything but ordinary. As Stanford assistant professor Ada Poon who heads the Stanford University engineering school suggested in her presentation to the ISSCC earlier this year, the day when we patients are able to “swallow the surgeon” may be a lot closer than we had imagined. Poon and her team have been exploring ways to use integrated circuit technologies and wireless communication models to enhance medical equipment.

While much work remains before these innovative devices can be used by doctors, the concept of small implantable medical devices is nothing new. Until recently, they have been limited by power constraints because the batteries are heavy would still need to be replaced from time to time. However, the device developed by Poon’s lab would allow for an external power source that is wirelessly powered by electromagnetic radio waves. Because they would require no cables or batteries, the devices could be used more readily in a variety of applications. The introduction of such devices would revolutionize medical equipment technology by offering everything from targeted diagnostics to heart probes, drug pumps and minimally invasive surgery.

New Developments Prevent Infection in Cardiac Devices

Knowing that the risks surrounding bacterial infections can be such a problem for implant patients, healthcare institutions are looking for ways to prevent Staphylococcus Aureus, also known as the “superbug” bacteria behind MRSA. A major problem for people with replacement heart valves and other medical implants, these bacteria form in colonies called biofilms; which land on the device and lead to widespread infections. For example, if this type of infection is contracted on a pacemaker, it could lead to a condition called endocarditis, a bacterial infection of the heart.

While these medical devices are relatively safe compared to some other implantable medical equipment technology, a new study has shed light on how these antibiotic-resistant biofilms are formed. Scientists in the biology department at Britain’s University of York found that biofilms release an unusually repetitive structure in the form of long, thin protein chains. These idiosyncratic patterns provide important clues to how these bacterial products might work.

One of the most important risks that results from a Staphylococcus infection like this is the removal of the affected device, which could result in more invasive and complicated procedures for chronically ill patients. However, learning more about how biofilms form will go a long way toward developing new ways to prevent device infections.

By identifying the clusters of bacteria that put so many heart patients at risk, researchers are helping medical equipment developers take steps toward prevention. Biofilms like this cannot be treated with traditional drugs or antibiotics, and thereby pose an extreme risk to patients who rely on implanted cardiac devices. These discoveries are an important step toward improved treatments and medical equipment techniques to prevent them from forming in the first place. As more is learned about the superbug infections that cause MRSA, medical institutions will be better prepared to protect patients from serious complications.

Externally Powered Medical Devices Mean No More Batteries

Flashlights and mobile phones both operate by battery with very little trouble, but the same type of battery power isn’t always feasible when it comes to medical equipment such as probes or implants. Fortunately, technical engineers and medical researchers have come up with a process that allows these systems to gain power without an external power source or cord.

Over the past fifty years, pacemakers have been used to set and maintain the rhythm of people’s hearts. During that same period, microelectronic implants have made dramatic advancements, becoming even smaller and more sophisticated than anyone dreamed possible. This trend has led to smaller and more intelligent systems that can be used to diagnose and treat illnesses; so much so that medical equipment manufacturers have created thousands of newer and smarter devices.

As an example of the movement to miniaturized healthcare, implantable sensors are now being used to measure blood pressure, glucose levels and oxygenation of tumors; all while using telemetry to transmit patient information. At the same time, infusion pumps and automated dosage systems are delivering a more targeted release of medication into the body; a practice that has been known to reduce side effects.

Medical equipment developers are constantly looking for new solutions to common medical problems that allow for more accurate and timely intervention. Far more technically advanced than the equipment doctors used just a few years ago, these solutions include signal processing units, actuators, probes and electronic controls that have long been used with a power supply. Using them within the human body has always required the use of wave-based or inductive systems, but these systems have inherent limitations with position, range and movement. Alternatively, the use of wireless power transmission from a portable transmitter to a mobile generator unit allows for a more reliable power source, which can be easily worn in a belt.

Developed by the Fraunhofer Institute for Ceramic Technologies, this small cylindrical device provides an impressive 100 milliwatts of electric current and has a range of approximately 50 centimeters. Wearing a power supply on a belt, it’s possible to operate medication dosing systems, supply power to internal implants and capture images from endoscopic capsules as the migrate through the intestinal tract.

The Facts about Purchasing a Used Hospital Bed

Purchasing a used hospital bed is a good investment, and one that should not be avoided or postponed for someone who is in need, and can benefit from having access to one. However, it is important to know what to look for in used medical equipment; the different types of beds that are available, and which model will best suit your needs. While most people may assume that hospital beds are all the same, there are actually a variety of beds that are best suited for different medical needs. Budgeting concerns make often make purchasing used medical equipment an attractive and realistic option. Knowing what features are needed and what you have to spend is an excellent starting point.

Types of Hospital Beds

Stetchers
Stretchers are beds that offer great mobility and are used to transport patients. They are most commonly used in ambulances and in emergency rooms.

Gatch Bed
A Gatch Bed is the typically the least expensive type of hospital bed because it does not require any electricity. They have three cranks that operate the bed to manually raise and lower different sections of the bed. These beds are often found in economically challenged medical facilities or areas.

Electric Beds
Electric beds are the type of bed that is most commonly used in hospitals. Buttons on the side rails allow patients and staff to raise and lower the bed at various levels.

Low Beds
Low beds are made for use with patients who are at greater risk if falling off beds and causing further injury to themselves. They are set to stand less than two feet from the ground. These beds are also made with the option of raising the head or foot of the bed if desired.

Low Air Loss Beds
Low Air loss beds are designed with special cushions and are most often used for burn patients and keeps them cool and dry, or for patients with circulatory or skin conditions. They are the ideal choice to reduce any pressure on the skin.

Circo-electric beds
Circo-electric beds rotate inside circular bars and are used for patients who must be rotated but cannot be turned over by a caretaker. These beds are typically used for patients that are in traction, have severe burns, or spinal injuries.

Clintron Beds
Clintron beds are filled with sand-like material and circulate dry, warm air through the bed to maintain a certain temperature and provide even support for the body. Clintron models are used for patients that have burn injuries, skin disorders, or pressure ulcers.

When purchasing a used hospital bed, be certain that all of the features are functional and that the mattress does not have significant wear. Furthermore, it is important to hire a certified technician to assemble the bed, to ensure that everything is secure and working properly. It is always best to order any used medical equipment you are purchasing from a reputable online dealer. Dealers sometimes offer free shipping, installation, and extended warranties on the products they sell.

Dentists Benefit from Buying Used Medical Equipment

Buying used goods at discounted prices is getting to be common practice nowadays. From used cars to gently used clothing from consignment shops, people are looking for bargains. The recession and high unemployment rates are creating a consumer society with a shrinking disposable income. Even small business owners are discovering the advantages to cutting back on their spending. By spending less money to equip their offices, medical providers are still able to offer quality health care and keep their employees on the company’s payroll. That is why purchasing used medical equipment is becoming a popular trend for more dental providers today.

Dentists often furnish their offices with used medical equipment. Often they purchase the equipment from larger dental clinics. It is highly probable that the patients they are treating will not notice anything different based on the equipment being used. A good health provider will not use any equipment for treatment that does not meet federal standards and is therefore in good working condition.

Purchasing used medical equipment offers several advantages to dentists. First and foremost, it is more affordable, and just as effective in treatment procedures as new equipment, therefore quality care is not compromised. Secondly, patients benefit since dental providers can keep their fees at more reasonable prices and that savings is then passed down to the patients. Thirdly, employees such as Dental Hygienists, Dental Assistants, and office personnel usually benefit when the practice is not struggling tostay afloat, in terms of job stability and salaries.

When buying used medical equipment for a dental practice, it is important to ask the seller educated questions. For example, the seller should disclose: the date the equipment was originally purchased, whether the seller was the first owner, clarify that all parts are in good working condition, and if there is a warranty on the device, in case any problems should arise. It is important that the buyer knows the history and the quality of the product being purchased.

Trying to Stick to a Budget? Don’t Rule Out Used Medical Equipment

It is a commonly known fact that technological advances occur rapidly these days. There is a saying that implies that a laptop computer purchased today will be obsolete tomorrow because of new technology. The technology that is used to create medical equipment is no different. It is also being updated and improved on a daily basis. Many hospitals, clinics and private medical practices are trying to keep up with the challenge of keeping their technology current, effective, and practical.

However, when equipment needs to be replaced or updated, often it can be a financial drain for any type of medical facility, especially in a fragile economy. For this reason, many of these facilities are opting to buy used medical equipment and discovering that it is a valuable solution, since used medical equipment, which is in good condition, and not outdated can be effectively productive for many years.

A healthy economy is often proves itself to be a wasteful economy. When businesses are thriving, budgets can be expanded to spend larger amounts of capitol on high-ticket price items. This type of economy can benefit the sales of used medical equipment, because often, more devices are readily available for purchase. A struggling economy will create less binge spending, less waste and more practical spending habits. Sadly, many hospitals and health care facilities are not able to purchase the latest equipment because of the current global economic recession, and this is a major factor as to why there is a rapidly increasing demand for quality used medical equipment.

It is important to remember, that anyone who is considering purchasing pre-owned medical equipment, should always make certain that it is purchased from a reputable and licensed dealer. Medical institutions and professionals can save thousands of dollars buying or selling well-cared for used medical equipment on the internet.

Financing Medical Equipment in Challenging Economic Times

Purchasing medical equipment, whether it is used, or new is a process that requires careful consideration, especially when assessing professional needs and budgets. There are a variety of different models and features that are available for purchase and reputable vendors have qualified personnel that will assist you with your needs. Patient demographics are also a valuable tool when you are determining what equipment you need and how frequently it will be utilized.

It is important to review all costs and benefits that are commonly associated with purchasing both new and used medical equipment. One benefit of newer equipment is that it attracts newer physicians, who are either intrigued or familiar with the latest technology in the practice of medicine. Another potential benefit of purchasing new equipment is that it often attracts an expanded patient base, which can greatly expand a physician’s practice. In previous years, when the economy was booming, hospitals and medical facilities predominately purchased new medical equipment.

Today, the healthcare industry is trying to manage costs just as other businesses are, as a result of the current recession and inevitable budget cuts. This has led to a higher demand for used medical equipment and parts throughout the country. Used medical equipment is frequently the more economical choice; however consumers should use caution when purchasing pre-owned items since they are sometimes sold without warranties. Pre-owned or used medical equipment normally becomes obtainable because a physician is upgrading equipment, relocating, or retiring. Hospital surplus is another reason that used medical equipment becomes available. However, when demand is high, supply is challenged and therefore more competitive. Consequently, sales of gently used and refurbished medical equipment is setting record breaking highs throughout the United States and Europe, and will most likely continue to grow over the next few years.

How to Donate Used Medical Equipment

Today many healthcare facilities are upgrading their medical equipment, and the question arises of what to do with the older, used medical equipment. Many pieces are in excellent working condition and are only slightly outdated. For this reason, many organizations are opting to donate their used medical equipment to other health care institutions and charities in the United States, and in other countries. This generosity enables donators to aid less fortunate health facilities by providing with the means to provide more adequate health care for the people they are treating.

The first order of business, when donating used medical equipment, is to be certain that the equipment is in good working condition. If any maintenance or repairs need to be done, they should be done before donating any equipment. Never donate equipment that is in need of repair, since there is no guarantee that it will be repaired before it is used to treat patients.

Once you are sure that the equipment is in good working order, deciding who and where to donate it is the next step. The internet is a helpful resource to use to find out who is in the market or in need of quality used medical equipment. Donating locally is usually more economical, since transportation costs are minimal. Many charitable organizations will eagerly accept the equipment, and they will handle everything, even determining which medical facilities are in need of those items. The AMRF (American Medical Resources Foundation) only charges a minimal fee to collect, test, repair, store, and eventually ship used medical equipment.

Lastly, as with any donation, keep a record of any paper transactions and receipts that are related to any materials that are donated for your tax records. The benefit of donating used medical equipment is two-fold; many patients will benefit from your charity and donations are tax deductible.

The AMS Fund is a great place to donate your used medical equipment.
