Engineer invented emergency drone: 1 minute to arrive at the scene
The defibrillator is built into the body of the drone, which means it can rescue the patient immediately after arriving at the scene. It is said that this emergency drone can increase the survival rate of patients with heart attack from 8% to 80%, which is equivalent to saving 300,000 lives every year.
In addition to being free of traffic restrictions, the drone itself is fast enough to reach 100kph, which means it can reduce the average response time from the current 10 minutes to 1 minute.
The drone's process for treating a patient is: it will fly to the patient's side (if the patient is indoors, it will land outdoors), and the person who makes the emergency call needs to be instructed by the medical staff (by phone) to understand How to use the defibrillator built into the drone and then shock the patient.
Although the patient's follow-up treatment still needs an ambulance to complete, if the heart attack patient is not treated within 5 minutes of the onset, his survival rate will drop to 8%.
Generally speaking, the Bolt is used to connect two objects, usually through the smooth hole, which needs to be used together with the nut, and a single bolt does not work. The tools are usually spanners. The head is mostly hexagonal, generally larger. The carriage bolt is used in the groove. The square neck is stuck in the groove during the installation process, which can prevent the bolt from rotating. The carriage bolt can move in parallel in the groove. Because the head of the carriage bolt is round, there is no cross groove or inner hexagon, which can be used to assist the design of tools. In the actual connection process, it can also play the role of anti-theft.
