Apple's phones have always been warmly welcomed by fans, and this iPhone 12 series launch is no exception. However, there is a discordant sound in the iPhone 12 series, the reason is that in a previous test, doctors found that the iPhone 12 in close proximity to an implantable defibrillator will make the device go into ? Pause? state. After a long period of research, Apple finally updated its iPhone User Guide, which warns users not to place the iPhone 12 and MagSafe accessories too close to medical devices such as implantable pacemakers. The reasons are as follows:?
1. iPhone 12 near a pacemaker could put the device? pause?
Implantable cardiac pacemaker a kind of electronic therapeutic device implanted in the body, its working principle is through the pulse generator timed to issue a certain frequency of pulsed current, through the wires and electrodes transmitted to the cardiac muscle contacted by the electrodes (atria or ventricles), so that the local cardiomyocytes are excited by the external electrical stimulation, and through the inter-cellular gap connection or intercalated disk connection to the surrounding cardiac muscle conduction, resulting in the excitation of the entire atrium or ventricle and consequent contractile activity. iPhone and all MagSafe accessories contain magnet components that generate magnetic fields and radios that may interfere with some medical devices when in close contact with these sensors. To avoid these interfering behaviors, Apple recommends that users maintain a safe distance of 6 inches (approximately 15 centimeters) between Apple devices and medical devices, and 12 inches (approximately 30 centimeters) when charging wirelessly.
2. Apple should have tested the devices beforehand to see if they would interfere with medical devices, such as pacemakers, and informed consumers.
The fact is that we live in an environment where ordinary household appliances basically do not have much impact on pacemakers, and most household appliances are safe to use, as long as there is no leakage of electricity, which generally does not affect pacemakers. However, patients will be told by their doctors to stay away from electronic devices such as cell phones when installing pacemakers, the reason being that if the pacemaker is disturbed, patients will experience varying degrees of discomfort, and those who are heavily dependent on the pacemaker may also experience symptoms such as vertigo again. So as a supplier, the iPhone 12 should have been well checked and experimented with before it was developed or sold, and its effect on pacemakers should have been tested ahead of time and communicated to consumers, who could then choose whether or not to buy it. It's clear that Apple didn't do enough in this regard, and it's good to see that he made up for it afterward.
