Technical Field
[0001] This invention relates to the field of smart wearable device technology, and more specifically to a wearable device based on fall location alarm technology. Background Technology
[0002] Falls are frequent in daily life, especially among the elderly, children, and those engaged in specific jobs or sports. Falls often cause varying degrees of injury, and in severe cases, can even be life-threatening. Traditional protective measures have many limitations. For example, most ordinary protective gear only provides simple physical protection and cannot provide warnings before a fall occurs, nor can it provide targeted protection based on the specific circumstances of the fall. Existing wearable devices also have shortcomings in fall protection. Some devices can only detect that a fall has occurred but cannot take effective cushioning measures to reduce the impact at the moment of the fall or before, and their protection of critical areas such as the head and neck is inadequate. Moreover, many devices lack positioning and alarm functions, and cannot promptly transmit location information to rescuers after a fall, leading to delays in rescue efforts. In addition, some devices, due to poor breathability, can cause discomfort to users during prolonged wear, affecting their normal use. Therefore, developing a wearable device with fall warning, comprehensive cushioning protection, accurate positioning and alarm functions, and good breathability is of significant practical importance.

When the miniature gyroscope sensor 2-4 detects a risk of fall, the circuit board 2-5 controls the opening and closing of the electromagnetic valve 2-8 to release compressed air from the metal airbag 2-11 into the silicone vest 1-1, causing the silicone vest 1-1 and the head and neck air curtain 5 to expand and cushion the fall. At the same time, the circuit board 2-5 controls the Beidou positioning module to locate the position and triggers the buzzer alarm.
[0030] Example 2: A wearable device based on fall location alarm technology. The vest component 1 is also made of silicone and has armholes and a collar.

[0031] Example 3:
[0032] A wearable device based on fall detection and alarm technology includes a vest component 1 made of silicone 1-1. It has armholes on both sides for easy arm movement and a neckline at the top for head and neck passage. Two abdominal ventilation openings 1-2 are located in the abdominal area of the silicone vest 1-1, a back ventilation opening 1-3 is located in the middle of the back, and two waist ventilation openings 1-4 are located on both sides of the waist to ensure breathability during wear. A ventilation component 3 is installed on the inner back surface of the vest component 1. The ventilation component 3 consists of multiple longitudinally and transversely arranged soft air channels 3-1 and a miniature air pump 3-3. The soft air channels 3-1 are hollow inside, and the side facing the body has multiple fine holes for blowing air outwards, enabling breathable treatment of the skin around the wearer. The miniature air pump 3-3 is fixed to the top surface of the outer shell 2-1 by a bracket. Its air supply end is connected to the air supply line 3-2, which extends into the inner cavity of the soft air tank 3-1 to provide airflow to the soft air tank 3-1.
[0033] A control component 2 is installed on the outer back surface of the vest 1. The outer shell 2-1 of the control component 2 is fixed to the outer back position of the silicone vest 1-1. A metal airbag 2-11 is fixed to the right side of the inner cavity of the outer shell 2-1. The top of the metal airbag 2-11 is equipped with an air injection nozzle 2-10, which can be used to inflate the metal airbag 2-11 and store it on a wall. At the same time, a pressure sensor is installed inside the metal airbag 2-11 to monitor the internal air pressure. A miniature gyroscope sensor 2-4 and a battery 2-6 are fixed to the left side of the inner cavity of the outer shell 2-1. A circuit board 2-5 is fixed to the top of the battery 2-6. The circuit board 2-5 integrates a Beidou positioning module and a buzzer alarm. The data transmission terminal of the miniature gyroscope sensor 2-4 is connected to the circuit board 2-5, which can transmit the monitored data to the circuit board 2-5. A solenoid valve 2-8 is fixed to the inner wall of the outer shell 2-1. The air inlet of the solenoid valve 2-8 is connected to an air supply pipe 2-9, which is connected to a metal airbag 2-11. The exhaust end of the solenoid valve 2-8 is connected to an exhaust pipe 2-7, which passes through the outer shell 2-1 and is connected to an air pipe 2-3 at its end.

The back surface of the outer shell 2-1 has an interface for the connection between the air supply and exhaust pipes 2-7 and the air pipe 2-3.
[0034] The top of the vest 1 is fixedly connected to the head and neck air curtain 5. Both the silicone vest 1-1 and the head and neck air curtain 5 are hollow inside, and their internal spaces are interconnected. The outer surface of the head and neck air curtain 5 has corrugations for expansion and contraction, allowing it to expand upwards and extend after inflation, providing protection for the head and neck. Multiple pressure sensors 4 are fixed to the outer surface of the vest 1 to monitor the impact force on the human body after a fall. Multiple non-contact vital sign monitoring sensors 6 are fixed to the inner chest area of the vest 1 to monitor the wearer's vital sign data in real time. When the wearer is in a potentially fallable situation, the miniature gyroscope sensor 2-4 detects relevant data and transmits it to the circuit board 2-5. The circuit board 2-5, based on a preset program, determines that there is a risk of fall and controls the solenoid valve 2-8 to open. Compressed air from the metal airbag 2-11 enters the silicone vest 1-1 through the air supply pipe 2-9, solenoid valve 2-8, exhaust pipe 2-7, and air pipe 2-3, causing the silicone vest 1-1 and the head and neck air curtain 5 to rapidly inflate, providing cushioning against a fall. Simultaneously, the circuit board 2-5 controls the Beidou positioning module to determine the wearer's location and triggers a buzzer alarm to ensure timely assistance.
[0035] Based on the above-described preferred technical solution, the workflow of the technical solution is explained as follows: Vest 1 is made of silicone vest 1-1, with sleeve holes on both sides for easy arm passage and a neckline at the top for head and neck passage. Two abdominal ventilation openings 1-2 are opened in the abdominal area of the silicone vest 1-1, a back ventilation opening 1-3 is opened in the middle of the back, and waist ventilation openings 1-4 are opened on both sides of the waist. These ventilation openings ensure the circulation of air between the human body and the outside environment when wearing the vest, thereby improving wearing comfort. A ventilation and breathable component 3 is installed on the inner back surface of the vest component 1. The ventilation and breathable component 3 consists of multiple longitudinally and transversely arranged soft air channels 3-1 and a micro air pump 3-3. The soft air channels 3-1 are hollow inside, and have multiple fine holes for blowing air outward on the side facing the human body. The micro air pump 3-3 is fixed to the top surface of the outer shell 2-1 in the control component 2 by a bracket. Its air supply end is connected to the air supply pipe 3-2, which runs through the inner cavity of the soft air channel 3-1. When the micro air pump 3-3 is started, it will deliver air through the air supply pipe 3-2 to the soft air channel 3-1, and then blow it out of the fine holes of the soft air channel 3-1 onto the skin of the wearer, thereby achieving breathability of the skin of the wearer and avoiding discomfort caused by stuffiness during prolonged wear.
[0036] A control component 2 is installed on the outer back surface of the vest 1. The outer shell 2-1 of the control component 2 is fixed to the outer back position of the silicone vest 1-1. A metal airbag 2-11 is fixed to the right side of the inner cavity of the outer shell 2-1. The top of the metal airbag 2-11 is equipped with an air injection nozzle 2-10. Before the device is used, air can be injected into the metal airbag 2-11 through the air injection nozzle 2-10 to put the metal airbag 2-11 into a wall-mounted storage state. At the same time, a pressure sensor is installed inside the metal airbag 2-11 to monitor the internal air pressure in real time and ensure that the metal airbag 2-11 can provide sufficient air pressure when needed. A miniature gyroscope sensor 2-4 and a battery 2-6 are fixed to the left side of the inner cavity of the outer shell 2-1. Battery 2-6 provides power to the entire device. Circuit board 2-5 is fixed to the top of battery 2-6. Circuit board 2-5 integrates a Beidou positioning module and a buzzer alarm. The data transmission terminal of the miniature gyroscope sensor 2-4 is connected to circuit board 2-5. During the wearer's daily activities, the miniature gyroscope sensor 2-4 monitors human posture and movement status in real time and transmits this data to circuit board 2-5. Circuit board 2-5 analyzes and processes this data according to a preset program. When it determines that the wearer is in a state where a fall is possible, such as abnormal tilting of the body posture, or a sudden change in movement speed and direction, which meets the preset fall risk conditions, the circuit board... 2-5 will trigger subsequent protection and alarm actions. A solenoid valve 2-8 is fixed to the inner wall of the outer shell 2-1. The air inlet of the solenoid valve 2-8 is connected to an air supply pipe 2-9, which is connected to a metal airbag 2-11. The exhaust end of the solenoid valve 2-8 is connected to an exhaust pipe 2-7, which passes through the outer shell 2-1 and is connected to an air pipe 2-3 at its end. An air nozzle 2-2 is embedded and fixed to the bottom surface of the silicone vest 1-1. The end of the air pipe 2-3 away from the exhaust pipe 2-7 is connected to the end port of the air nozzle 2-2. The back surface of the outer shell 2-1 has an interface for the air supply and exhaust pipes 2-7 to connect with the air pipe 2-3. When the circuit board 2-5 determines there is a risk of falling, it will control... When the electromagnetic valve 2-8 is opened, the compressed air inside the metal airbag 2-11 enters the silicone vest 1-1 through the air supply pipe 2-9, electromagnetic valve 2-8, exhaust pipe 2-7, and air pipe 2-3, causing the silicone vest 1-1 to expand rapidly. The top of the vest 1 is fixedly connected to the head and neck air curtain 5. Both the silicone vest 1-1 and the head and neck air curtain 5 are hollow, and their internal spaces are interconnected. When the silicone vest 1-1 is inflated, the head and neck air curtain 5 will also expand. The outer surface of the head and neck air curtain 5 is provided with corrugations for its expansion and contraction. After inflation, it can expand upwards and extend to protect the head and neck, reducing the impact force on the head and neck when falling.
[0037] Multiple pressure sensors 4 are fixed to the outer surface of the vest component 1. During a fall, the pressure sensors 4 monitor the impact force on the body in real time and transmit this data to the circuit board 2-5 for more detailed analysis and recording of the fall. At the same time, the circuit board 2-5 controls the Beidou positioning module to determine the wearer's current location information and stores it in the storage unit of the circuit board 2-5. Simultaneously, it triggers a buzzer alarm to attract the attention of those around and facilitate timely rescue. Multiple non-contact vital sign monitoring sensors 6 are fixed to the inner chest area of the vest component 1. During the wearer's use of the device, the vital sign monitoring sensors 6 monitor the wearer's vital sign data, such as heart rate and respiratory rate, in real time and transmit this data to the circuit board 2-5. The circuit board 2-5 can analyze and process this vital sign data in real time. When abnormal vital signs are detected, the location can also be determined through the Beidou positioning module and an alarm can be triggered to facilitate timely rescue of the wearer.
