Researchers from abroad have developed a wireless brain sensor that can monitor intracranial pressure and temperature, but also can be absorbed by the body, to reduce surgical removal of routine monitoring of equipment. The researchers pointed out that the implant as such can be used to monitor patients with traumatic brain injury, but they think we can build a similar sensor can be absorbed for monitoring activities in the organ systems throughout the body, research published in the International the magazine Nature.
Researchers Rory KJ Murphy said, in recent years, electronic devices and the rapid development of medical devices, is currently the biggest obstacle we face is that the implant will often induce specific immune responses, which the patient or the existence of certain risks; but these devices for patients benefit is its will slowly dissolve over time, the use of such sensors can also reduce the solubility surgeon surgical removal of the equipment required, which greatly reduces the risk of infection and complications of the patients body.
In the United States there are about 50,000 people each year die from trauma, such as traumatic brain injury, when a patient enters the hospital for treatment, the doctor must be conducted in patients with intracranial pressure measurement, because of the increased intracranial pressure often lead to further brain damage and the current through the brain scans and clinical characteristics, doctors can not reliably determine the patient's intracranial pressure. The researchers pointed out, but the most commonly used devices are based on 1980s technology developed, these devices larger, use more cumbersome, but also in the intensive care unit with its need to connect an external monitor to use. The new sensor developed by the researchers of this article, which is mainly composed of a polylactic acid polyglycolic acid (PLGA) and a silicone composition, but it can transmit accurate pressure, temperature, and other parameters. With the design and development of advanced materials and equipment, researchers might develop a more accurate implant electronically, and thereby facilitate the clinician operation.
