Description

TECHNICAL FIELD

[0001] The present application relates to an efficient AED delivery device, in particular to a small unmanned aerial vehicle AED delivery device and an AED delivery method using the same. BACKGROUND

[0002] Medical care is a basic problem in human society, and many times the patient's condition is critical due to delays, ambulance delays, etc. An automatic external defibrillator, also known as an automatic external defibrillator, is a portable medical device that can be used by non-professionals for the treatment of patients with cardiac arrest. The most effective way to stop sudden death in the world is to use AED to defibrillate and cardiopulmonary resuscitation in a timely manner. However, the current AED usage rate in China is low, and once a patient's heart stops, they need to be sent to the hospital immediately. In the event of a traffic jam or other unexpected situation, it will delay the golden time of treatment, and in severe cases, it will endanger the patient's life safety.

[0003] The use of AEDs in densely populated areas in China is low, and patients will often face problems such as being too far from the hospital or being unable to approach large equipment / ambulances carrying AEDs in densely populated areas. When such problems occur, the best rescue time is often missed. To address similar problems, some people have proposed a scheme to transport AEDs by unmanned aerial vehicles, allowing AEDs to quickly and efficiently reach designated locations. In practical applications, it has been found that there are two ways to deliver AEDs by unmanned aerial vehicles. One is to drop AEDs from the air at a predetermined air space and altitude, and the other is to land AEDs on the ground by unmanned aerial vehicles, and then rescue personnel remove AEDs from the unmanned aerial vehicles.

[0004] In these two schemes, dropping AEDs from the air can easily cause AEDs to be damaged or deformed, which can lead to AEDs not working properly. Unmanned aerial vehicles need to land on a relatively flat and suitable landing site, and sometimes it is difficult to quickly find such a landing site, which can cause AEDs or unmanned aerial vehicles to be damaged during landing, affecting the use of AEDs or rescue work.

[0005] In addition, in order to make the quick reach range of unmanned aerial vehicles cover all densely populated areas, a large number of unmanned aerial vehicles carrying AEDs need to be deployed, which requires the unmanned aerial vehicles and related carrying and delivery equipment to be as simple as possible, easy to operate, reduce costs, and have low failure rates and high reliability.

[0006] Based on the above-mentioned practical problems in the process of transporting AEDs by unmanned aerial vehicles, the present application has conducted in-depth research on AED delivery devices in order to design a small unmanned aerial vehicle AED delivery device and an AED delivery method using the same to solve the above-mentioned problems. SUMMARY

[0007] In order to overcome the above problems, the present inventors have made intensive studies and designed a small unmanned aerial vehicle AED delivery device and an AED delivery method using the same. The device comprises a storage box for storing an AED, two buckle connecting frames connected to the top of the storage box, and a rotating buckle provided on the top of each buckle connecting frame. The rotating buckle is connected to a motor, and the rotating buckle is controlled by the motor to connect or disconnect with the buckle connecting frame. When the two rotating buckles are completely disconnected, the delivery of the AED is completed. The two buckle connecting frames are at different heights, so that the storage box has an inclination angle of 30 degrees. When the storage box is delivered, the two rotating buckles are unlocked in a specific order, so that the unmanned aerial vehicle can be smoothly picked up by the user of the AED in a hovering state to unload the AED in the most stable way, ensuring that the AED will not be damaged by vibration during unloading and ensuring that the AED can be used normally. Thus, the present application is achieved.

[0027] Wherein, a flexible protective pad layer 11 is arranged at the bottom inside the storage box 1;

[0076] The device further comprises a front buckle connecting frame 3 and a rear buckle connecting frame 4, the front buckle connecting frame 3 and the rear buckle connecting frame 4 are respectively connected with the lifting lug 2, so that the storage box 1 is fixed in an inclined state at the bottom of the unmanned aerial vehicle, as shown in the figure. Figure 1 The front and rear in the application are determined based on the traveling direction of the unmanned aerial vehicle, and the forward direction of the normal flight of the unmanned aerial vehicle is the front, and the opposite direction is the rear.

[0082] In a preferred embodiment, when the unmanned aerial vehicle is in a horizontal state and carries the storage box 1, the bottom end height of the front buckle connecting frame 3 is higher than the bottom end height of the rear buckle connecting frame 4, that is, the storage box is in an inclined state, and the inclined state can be produced by adjusting the height positions of the two motors, and the inclined state can also be produced by arranging different buckle connecting frame heights.

[0083] In a preferred embodiment, the inclination state of the storage box 1 is that the angle between the storage box 1 and the horizontal plane is 25-40 degrees, preferably 30 degrees, when the UAV is in a horizontal state. At this angle, the front end of the storage box 1 is not high from the ground, and the flexible pad 13 at the bottom of the storage box 1 has good cushioning effect, so that the storage box 1 will not be subjected to excessive impact when falling and affect the AED. And at a certain inclination angle, the AED device has good position constraint inside the box due to gravity, preventing the AED device from colliding with the inner wall of the box due to UAV flight, thereby damaging the AED device. Considering the forward inclination of the UAV during forward flight, and considering the influence of the shape of the UAV and the attached device on wind resistance, setting the angle to 30 degrees can maximize the flight speed of the UAV, and also ensure the safety of the AED in the storage box without damage.

[0084] In a preferred embodiment, when the UAV drops the storage box 1, the front motor 7 and the rear motor 8 are started according to a predetermined sequence / rule.

[0089] The front motor 7 is started after a predetermined time, and the predetermined time is 1-2 seconds.

[0090] Further, when the UAV reaches the location near the user, first, whether the UAV can land is judged according to the observation of the terrain near the user, if the UAV can land stably, the UAV lands to unload the AED, if the UAV cannot land stably, the UAV hovers to unload the AED; after the UAV completes the unloading of the AED, the UAV rises to a second predetermined height, and waits for the rescue to end, and the second predetermined height is about 5-10 meters from the ground.

[0095] Preferably, an annular spring 53 is further arranged in the shell 51, which presses the buckle joint 31 to a position away from the opening 52. Preferably, the annular spring 53 is arranged symmetrically with two. The annular spring is pressed together with the buckle joint, and when the motor starts to work, the rotating power of the motor is opposite to the elastic force provided by the annular spring, which can press the annular spring, so that the horizontal rod section returns to the position of the opening 52, thereby allowing the buckle joint 31 to be separated from the shell 51.
