    accuvein.com

    AccuVein is a private US that develops products that facilitate the visualization of peripheral vasculature.

    AccuVein – AV400 – displays in real-time digital map of the vasculature on the skin surface, allowing doctors to check the patency of the vein and prevent valves and bifurcations. The veins are shown because the hemoglobin in the blood absorbs preferentially light to infrared rays. For this reason, the vascular system displayed represents the contents of the veins and not the entire vein. The AccuVein system is portable and lightweight, weighs only 275gr. Venipuncture is a procedure that requires that both hands are free, then AccuVein is equipped if necessary of supports on wheels or stationary in a position to allow the user to keep the device above the patient’s body and at the same time having full mobility. The design allows the device to be easily cleaned and sterilized. AV400 is aligned permanently. Use is made more easier by the possibility for AccuVein to rotate in any direction above the vein displayed, this makes AV400 useful on a variety of patient types. The accuracy when precision, up to the width of a human hair, allows AccuVein detect veins up to 10 mm depth. The innovation is in response venipuncture procedures more effective and greater satisfaction among patients, which makes it clear why many facilities have chosen to integrate AccuVein in their standard of care.

    SYSTEM INCLUDES

    • AV400 unit including battery
    • Charging Kit
    • Universal power supply, and multinational adapters

    The device AccuVein reduce 39% pain in cases of venous access difficult – DVA -such as in patients with a BMI of more than 35 . increased of success increased from 50% to 96% marking an important turning point for all those who have a DVA. In the pediatric field the system represents a true revolution. Medical professionals know that venipuncture can be especially difficult in some patients. Among which:

    • The elderly
    • Patients with dark skin, in which the veins are not highly visible
    • Patients Obese, in which the veins can not be visible or palpable
    • Patients who have many diagnostic or therapeutic procedures intravenously
    • Burns
    • Cancer patients in chemotherapy
    • Addicts

    Not are omitted at this point the advantages from the economic point of view. The cost savings using AccuVein far exceeds the cost of normal needles – about $ 100,000 for each company hospital – if a service of hospitalization were to use AccuVein even once a week, there would be a cost savings of around three times and risk prevention of serious infection would be a further significant benefit. The device is also used by the educational point of view of future doctors, nurses and paramedics during their internship. They say AccuVein:

    “In my 29 years of service as a paramedic, this is one of the few times I’ve used a tool that improves the response with patients, reduces the risk of infection and allows cost savings. AccuVein is a real lifesaver. ”
    – Paramedic in Birmingham –

    “Where is it? We need it! Other departments are jealous that we AccuVein.”
    – Children’s Research Hospital, department of anesthesia –

    “The patient was surprised, frankly, I too!”
    – Medical Director of Vein Clinic –

    AccuVein demonstrates again as research and technology is a perfect combination and efficient to assure the protection and welfare of each of us.

    A new robotic arm controlled by thought for tetraplegic

    An innovative new robotic arm controlled directly by thought through microelectrodes implanted in the brain has given the opportunity to Erik G. Sorto, paralyzed for 13 years due to a spinal injury, to grab a glass to drink.

    The subject is thus able to control the paralyzed arm, thinking only to the objective to be achieved. The study published in “Science” shows that the innovative approach, the result of a collaboration between the California Institute of Technology, University of Southern California and Rancho Los Amigos National Rehabilitation Center, has allowed to overcome some important limitations that occurred with neuroprosthesis made so far.

    In fact, the most used technique involves the implantation of microelectrodes in the area of brain that controls the movement: the motor cortex. This movement, however, is suffering from two problems: a slight tremor and a delay from the input of the patient.

    The winning idea was to take advantage, as the venue for the electrodes, another area of the brain: the posterior parietal cortex. It is delegated to higher cognitive functions, such as the formulation of the intention to make a move. In this way it was possible to eliminate that delay this with previous systems getting smoother motion and movement similar to the real. In fact, the posterior parietal cortex is placed at the beginning of the neural path that reaches the limbs.

    The new mechanism has thus led to have a result by simply thinking about the movement, as in normal situations, without having to think about which muscles to activate and without thinking about the details of the movement.

    Erik Sorto started, in 2013, a training program that allowed him to control earlier the cursor of a computer, coming today to manage a robotic arm.

     

     

    Emblem-S-CID

    Emblem S-ICD: subcutaneous defibrillator without implantation in heart valve

    Cardiovascular diseases are part of the most frequent causes of death throughout the world. Among them we also find the so-called sudden cardiac arrest (SCA), functional alteration that can lead to death if not treated promptly and responsibly every year 350,000 cases pathogens in Europe, including 50,000 in Italy.

    These figures are extremely substantial, that Boston Scientific is helping to elide with Emblem S-ICD, the second generation of defibrillators subcutaneous, able to constantly monitor their heart rate and check for potentially deadly ventricular tachyarrhythmias, with a small electrical discharge helpful to adjust the rhythm and restore normal blood flow. Second generation that reveals how much has been done, in a few years, in terms of technological evolution, efficacy and safety of care and clinical sensitivity.

    To better understand and appreciate this innovation we consider a parallel between:

    bostonscientific.com

    Transvenous ICD (previous generation): implanted under radiographic guide, the area of the left shoulder, near the collarbone, has electric wires inserted through a vein directly into the heart valve. Depending on the condition of the heart, they will be placed 1 or 2 leads. After being placed in position, the leads are connected to the heart wall for connectivity and an optimal monitoring.

    Emblem S-ICD:the pulse generator and the electrode system Emblem S-ICD, under the guidance of anatomical landmarks, are implanted under the skin on the left side of the body, near the rib cage. The system Emblem S-ICD delivers therapy without the need to implant wires in heart valve leaving intact heart and blood vessels.

    It is clear that it is a transvenous ICD that Emblem S-ICD are designed to deliver a defibrillation (electric shock) life-saving in the case of sudden cardiac arrest (SCA) or heart failure.

    We reach, now, to the fundamental differences: they reside precisely in the total absence Emblem for S-ICD of contact with the heart, in order to minimize the invasiveness and maximize the effectiveness. Emblem S-ICD leaves the heart and vascular system intact analyzing heart rhythm, rather than individual beats, avoiding potential complications associated with transvenous leads in the ICD. Also – Another essential point – lies in both its battery life of about 7 years, equivalent to a longevity of 40% greater, both in a device thinner by 20%.

    Last but not least, remember that came with Emblem S-ICD’s innovative “management of patients at a distance”, by Lattitude NXT, the system that makes it easy for healthcare professionals anytime access to information and operating status pacemaker in their patients, allowing also alert notifications via text message or e-mail.

    All this avoids the complications associated with transvenous leads, that is:

    • Endocarditis
    • Drilling
    • Hemothorax
    • Pneumothorax
    • Thromboembolic events
    • Vascular complications

    Gaining with:

    • The elimination of potential vascular damage
    • The reduction of a potential systemic infection
    • Maintaining intact venous access
    • Exceptional resistance to manual cardiopulmonary resuscitation (CPR)
    • An isolated system in polyurethan

    We end this discussion with a witness:

    When you diagnose a heart condition like that you’re not the only one to pay the price – he said talking about his family, Graham Harper, one of the patients who Emblem S-ICD has changed my life. Being able to do what you want when you want, live your life normally, safely. The device protects you every day, 24 hours on 24, and now my wife and my children no longer worried when I travel alone … only care about the security guards at the airport, when I get to the metal detector.
