Electronic enthusiasts core tips : Many of the ideas in medical electronic devices are not new inventions. A slight improvement of the original medical electronic devices may produce new uses; and many of the so-called "low technology" are only used in Suitable places can also have a major effect on disease prevention. Gastroparesis treatment instrument As early as the 1960s, Western researchers invented a cardiac pacemaker to correct severe arrhythmia and help patients return to normal heartbeat. However, little is known that cardiac pacemakers can also be used to treat mild to moderate gastroparesis. At present, there is a lack of effective drugs for gastroparesis on the market. Not long ago, scientists at the National Children's Medical Center of Ohio State University improved the pacemaker slightly, making it "transformed" into a gastroparesis treatment instrument. According to reports, the electrical stimulation signal sent by this treatment instrument can stimulate the gastric nerves, thereby promoting gastric motility, allowing the food in the stomach to be quickly discharged into the small intestine, and eliminating the symptoms of bloating caused by gastroplegia patients after eating. The doctor needs to implant this treatment device under the skin of the patient, and connect two electrodes on the stomach wall of the patient. According to reports, so far, many adult and children with gastroparesis in the United States have received gastroplegia treatment instrument implantation, and have achieved certain clinical results. Surgical "machine snake" More than 20 years ago, the United States developed a "machine snake" used on the battlefield. It can walk into the enemy's house like a snake to conduct investigations, and send the investigation results wirelessly. The robot snake can also enter the damaged house after the earthquake to check for signs of life. Two medical experts in the United States saw the potential use of robot snakes in surgery-the United States performs more than 1 million heart operations and more than 10 million endoscopic and laryngoscope operations every year. If we can develop a machine snake with a relatively small diameter that can travel in the body or in the cavity, and find lesions and perform surgery, many medical problems can be solved. According to reports, the US surgical snake has completed clinical trials. According to the developers, the surgical machine snake is only a few millimeters in diameter and is made of new engineering plastics. Medical staff can assemble it one by one to form different lengths as needed. During the treatment, the doctor needs to make a very small blade on the patient's body, let the surgical machine snake drill into it, and make it reach the target lesion under wireless command. The head of the machine snake is equipped with a miniature camera, which can photograph the condition of the lesion and wirelessly feed back the data to the doctor's computer. Surgical robot snakes have a wide range of clinical applications, such as heart repair, nerve repair, blood vessel repair, and blood vessel expansion. The biggest advantage is that it is used for surgery, the patient has a very small knife edge, little bleeding, and recovers quickly after surgery. Wearable defibrillator The US Zoll Medical Device Company developed the world's first "wearable atrial defibrillator". Patients can wear it around the waist to treat cardiac arrest caused by atrial fibrillation. Because of its novel design, this product won the "North American Healthcare Product Creative Award". Although there are various types of external defibrillators on the market, these devices are usually bulky and very inconvenient to carry. The wearable atrial defibrillator is compact and easy to use, and is suitable for patients with heart disease who go out frequently. The device consists of a shoulder strap (a pocket biosensor capable of measuring abnormal heart signals such as atrial fibrillation) and a detector of the size of an ordinary electronic dictionary (usually hung around the patient's waist). Its working principle is: the sensor can continuously monitor the heartbeat, and once the abnormality is detected, the defibrillation function is turned on, and the patient's heart rate is restored to normal through electrical pulse stimulation. Rapid temperature lowering device (TSS) The American LRS Company invented a rapid temperature lowering device (TSS) that can lower the body temperature to 32 ℃ ~ 34 ℃ within 30 minutes, and the company won the "North American Creative Healthcare Medical Product Award". Many clinical emergencies require rapid reduction of body temperature, especially emergencies such as cerebral hemorrhage and myocardial infarction. If the patient's body temperature can be quickly reduced to the target temperature, the mortality rate can be reduced by 50%. This is because the rapid lowering of body temperature helps reduce the oxygen demand and metabolic rate of the brain and heart, which in turn reduces brain damage and myocardial damage caused by hypoxia. According to the manufacturer, TSS is very convenient for medical staff to use. The use of TSS for critically ill patients (such as cerebral hemorrhage, myocardial infarction, etc.) who urgently need to lower their body temperature can quickly reduce the temperature of the patient's brain, heart and other important organs by 4 ℃ ~ 5 ℃. "Adhesive plaster type" monitor British Toumaz Technology has developed a revolutionary "Wireless Vital Signs Index Transmitter", which looks like a normal rubber plaster (just a little thicker). As long as the patient puts this special "adhesive plaster" on his chest skin, the measuring instrument can automatically measure multiple vital signs data and send the data to the doctor's computer in real time.
