By developing the technology of ultrasound, microwave, laser and infrared light has succeeded in developing a wide range of medical devices that act through electromagnetic waves, sonic or physical. Most important is that these devices are available to any user, and you can get a good home oximeter for a small investment of 100 or 200, although some houses have as Quirumed cheaper models by just over 60 euros plus shipping shipment. In hospitals are classified as having a fixed oximeter plethysmographic curve but for private use or educational enough portable pulse oximeter, hand or finger. Nonin is one of the brands that specialize in pulse, you indicate both the oxygen values as the number of heartbeats per minute.

The normal values of oxygen in blood vary between 95% and 97% SaO2 so easily detected irregularities to be decreases below 95% saturation of O2. Go2 Nonin finger pulse oximeter is cheaper brand, you can buy for $ 99 in a few days pmedicalonline.net and start making the first tests with your own finger. It is designed to be used with fingers of size from millimeters to a centimeter and has 2 year warranty. Among the additions, plus a charger Go2 also have some support for adequate transportation, avoid losses and protect against falls, such as a bag, a briefcase and a simple string. There are several other notebook models Nonin 9500 Onyx from $ 200, and handheld pulse oximeters from $ 400 to $ 600 as the Nonin 2500 PalmSAT.

The main functions of this is patient care and monitoring the level of oxygen in cases of asthma there may be respiratory distress, cyanosis, control of oxygen therapy and the assessment of exercise tolerance. So that according to these functions can perform tests to see how exercise or changes in breathing may alter the level of oxygen in blood. You can also perform other experiences related to research projects specific to the Baccalaureate, to correlate the age with the amount of oxygen in the blood, or measure differences in this value between men and women.

In clinical practice are complementary to the gases, and are widely used in pediatrics to be the least invasive and most friendly to children. So a little ingenuity can be placed permanently if necessary, and notify you of any decrease in blood oxygen saturation. The main disadvantage of these devices is that regard, a gas analysis provides less information: do not measure the concentration of carbon dioxide, or the blood pH, and also for oxygen values are accurate only above 80-90%, so that are not useful for certain pathologies. As advantages we should mention its use simple and fast, in addition to its noninvasive application already discussed earlier.

With these data, patients may tune in the administration of doses, avoiding physiological complications arising from an excess of insulin. In four years it is expected that the technology is available on the market. Scientists say it is very necessary because diabetes is increasingly present in our society as a result of lifestyle we lead. For Yaiza Martínez.

Diabetics can reduce the amount of insulin that administrate with the help of a new portable and wireless device designed to predict blood glucose levels.

This device, known as “DIAdvisor ™” will be developed by the company Toumaz Technology, specializes in manufacturing wireless devices and low power consumption to control the body. The project falls under the Seventh Framework Program of the European Community, which has earmarked 7.1 million euros.

The purpose of development of this device is to improve the lives of millions of diabetes patients, with an art tool for personalized prediction of blood glucose levels, reports Toumaz Technology in a statement.

The tool will be created thanks to a partnership of 13 doctors and several industry partners and academics. The work will be coordinated by Novo Nordisk company specializing in the care of this disease.

What is

DIAdvisor technology (Personal Glucose Predictive Diabetes Advisor) will be based on a wireless control technology of the body, existing and belonging to the company Toumaz Technology Sensium call.

Sensors consist of small, wireless and discreet, surrounded by a silicium chip low-power, which will stick to the body of the sick to log certain data, such as body temperature, blood pressure, blood glucose levels or oxygen, among other parameters.

According to The Engineer magazine reported online, the system transmits this data to a portable mobile device like a PDA or PDA. By hand, it may also introduce any other information you want, like food that has consumed the patient.

All these data will be analyzed later by an advanced algorithm to determine glucose levels in the patient’s blood at any particular time. In this way, patients will know in a matter of minutes, the amount of insulin will be administered at the next dose.

Breakthrough
According to Keith Errey, co-founder and president of Project Toumaz, current techniques for managing diabetes does not offer the ability to predict blood glucose levels in the short term. This means that patients should almost assume the amount of insulin they need to recover the stable levels of blood glucose.

Scientists hope, moreover, that this technology serves to avoid the risk of blackouts suffered by diabetics when their blood sugar levels drop dramatically. Many of the sick, in fact, prefer to consume higher doses of insulin than necessary to avoid the crisis, but the excess insulin also has its risks, including possible damage to the eyes, heart or liver.

But before he can see the light DIAdvisor are still important steps to take, how to define the combination of vital signs that provide the best information to determine the blood glucose level. For this, scientists will have a team of volunteers with diabetes to help generate the physiological models and prediction algorithms.

Within two years, will begin clinical trials in which they will operate these algorithms in real time and test the prediction models. If everything runs according to plan for the scientists, the technology will be available in the market within four years.

Technology increasingly necessary
According to published Toumaz, the massive increase in the incidence of diabetes is now a major global health challenges. This increase is due to demographic trends clear, as the epidemic of obesity, aging, or the spread of sedentary lifestyles.

All these factors have caused a massive spread of diabetes, especially type 2. In the case of type 1 diabetes, the pancreas does not produce insulin, but in the pancreas of type 2 if that makes it, but the body assimilates as it should.

Consequently, the pancreas produces more insulin to get glucose into cells, and just exhausted due to excessive strain. In addition, blood sugar levels get too high.

In the European Union, the average prevalence of this disease is 7.5% but is expected to increase to 16% in 2025. Scientists hope that, with DIAdvisor, it can provide a sophisticated treatment of the sick, thus enhancing self-management of disease and reduce the risk of serious complications resulting from poor control of glucose levels in the blood.

Blood glucose is one of the tiresome duties in everyday life for many diabetics. If you value good blood sugar levels, must stick to it several times a day with a small needle. This makes the measurement of unpleasant and leaves the skin susceptible to suffer sometimes. For people who are very sensitive to pain or have fear of needles, the procedure for torture

As long as one does not cure diabetes mellitus, is the research focus on minimizing any side effects. This includes sore finger or the fear of the stinging. So tried the medical devices industry for many years in the production of so-called “non-invasive” blood glucose measurement system. This required a measurement that indicates, without any physical interference with the integrity of precise figures. A non-invasive blood glucose monitoring system requires no blood and therefore without the sting. Until now, such systems are the future. Although eager to research prototypes, but so far none of the products reached the market.

Swiss companies including test series with non-invasive device
The Solianis AG, a medical technology company with headquarters in Zurich, could be among the first to develop a working, non-invasive meter. On 8 December, ceremonies 2008 was successfully completed a series of tests: 12 People with diabetes have not had an invasive blood glucose meters and tested at home and at work over a week. The results of this study that the glucose monitor of blood glucose fluctuations in daily Solianis as reliable as conventional display devices. “This is the first study ever conducted on a non-invasive blood glucose monitoring system in a home test and the workplace. The data show clearly that the technology works, and that we can bring this device is now ready for series production,” says Mario Stark, CEO of Solianis .

Coming soon to a breakthrough for non-invasive blood glucose measurement?
For all the enthusiasm, the company will not raise false expectations: after all, the technology is not yet so advanced that we could all do without the stinging. Be checked for calibration of the new device, the blood sugar level with a conventional meter and this one still needs the unloved stab in the foot. Even if the new blood glucose monitoring device sounds the alarm, you should first check the blood sugar level with a conventional test strips before they take countermeasures. In the non-invasive device if it were therefore more of a supplement in the daily blood glucose control than a true replacement.

How does the Solianis device?
That is not monitored by measuring inasive Solianis with several sensors, different physical features: In addition to sweat is collected, the moisture content of the skin. The change in skin thickness and variations in their blood are among the most important factors of non-invasive measurements of blood glucose. This body’s reaction, however, influenced by environmental factors that produce interference with the meter. With additional sensors, the confounding factors should be collected to enable the correct display of blood glucose levels. In addition to the sweat sensor, the researchers used sensors with different geometries in the same chip that run in a mega-to gigahertz range. They generate an electric field and depending on which wavelengths are measured in the skin layers, the sensors respond to changes in glucose budget. Disturbances that occur above the perfused skin, this should also be measured and corrected for the values can be calculated. Moreover capture an optical sensor, the changes in blood flow to the skin can.

When the non-invasive device to come on the market?
Following the success of the test series with the AG Solianis diabetic patients, their first measuring systems in Europe 2010 plans to bring to the market if the EU release these devices. The first devices are designed for type 1 diabetes are being developed. The company is confident about entering the global markets: To advance the development of prototype instruments without jump, the Board has Solianis and two other experts verstärkt.Für type 2 diabetics and other patients with impaired glucose tolerance follow-up models will be produced.

Thus the blood pressure but can be successful and will be sent to exact values, certain guidelines are met. Is always measured on the inside of the wrist. The cuff is applied to the artery. To obtain accurate measurement data, it is necessary to first consider the wrist at heart level to. The short time that requires a blood pressure measurement should be spent in silence. That is, it is a relaxed position – for example, sitting or lying position to take -. Nor can it be said, to avoid incorrect measurements during the measurement. Fairs give instructions on how to correct the manuals of the wrist blood pressure monitors that are located in the packaging of products.

The calculated pressure is shown on a display. There appear several levels – firstly, the systolic, upper blood pressure and secondly, the diastolic, the lower pressure. In addition, modern digital blood pressure monitors also indicate the pulse rate.
