detailed description

The invention can automatically detect whether a swimmer is drowning. If the swimmer falls into dangerous situations such as cramping, choking or fainting in the water and cannot swim independently, the swimmer cannot perform effective self-rescue and endangers life safety. The device automatically starts the gas generator 2 to inflate the elastic air bag, and starts an alarm to realize self-rescue from drowning.

The present invention is composed of light rigid collar 5, gas generator 2, annular elastic air bag, drowning detection and alarm unit 1 and other four parts. The composition and function of each component are introduced below.

Rigid collar 5: This collar is adjustable in size and has a certain degree of rigidity. It needs to be made of a material with low density and strong rigidity. The circle edge line of the collar is a grooved inner arc structure, the gas generator and the annular elastic air bag can be placed on the collar, and at the same time, the swimmer's throat can be protected from being squeezed by the inflatable bag.

Gas generator 2: The main function is to generate gas to inflate the annular elastic air bag. The two ends of the gas generator along the arc direction of the collar respectively have an air outlet which is sealed and connected with the annular elastic air bag. The gas generator can be activated by receiving commands from three parties, such as the inflation start command of the drowning detection module, the start command sent by the heartbeat detection wristband, or the safety switch is activated to generate gas to inflate the annular elastic air bag. The working principle is that an appropriate amount of NaHCO3 solid powder is placed in the gas generator, and the metal heating grid is placed in the powder. The metal heating grid is connected in series to a battery-powered normally open circuit with on-off control. When the switch is closed, the circuit is connected to the heating grid quickly. Heating up NaHCO3 releases a large amount of CO2 gas, and inflates the elastic air bag through the inflation ports at both ends. After heating for several minutes, the circuit is disconnected to stop heating.

Ring-shaped elastic air bag: made of a certain degree of elasticity and scratch-resistant material. Both ends of the air bag are connected to the two inflation ports of the gas generator 2, and are connected with the gas generator 2 to form an airtight whole, which has the characteristics of waterproof and good airtightness. When the gas generator produces CO2 gas, it will be inflated into the elastic air bag through the gas outlet to form a life buoy stuck on the head, and the head of the drowning person will be dragged and floated on the water surface.

Drowning detection and alarm unit 1: This part is a sheath-type structure, similar to a spectacle frame, which can be placed on the swimmer's head with the support of the auricle and nose. The frame of the back of the head is provided with a battery-powered detection and alarm circuit. The circuit is normally open, and the circuit is insulated from the outside. Two detection probes are drawn out from both ends of the circuit and placed at the swimmer's nostrils so as not to hinder breathing. When the swimmer's nostrils are not in the water, the two open-circuit end detection probes of the normally open circuit are connected through the water to start working. Run the control program for timing. If the nostrils are not in the water within the preset time, it can be judged as drowning. When the timing is reached, an inflation command will be sent to the gas generator immediately and an audible and visual alarm signal will be issued to remind people on the shore or swimming nearby in the water. to rescue. The gas generator and the drowning detection and alarm module are connected by elastic soft waterproof cables, and each component is connected to form a sealed waterproof body.

Specifically as shown in Figures 1-4, the present invention comprises that the swimmer's neck is covered with a rigid collar 5, and the inside of the rigid collar 5 is provided with an elastic air bag, and the air inlet of the elastic air bag is connected to the gas generator 2, and the gas is generated. The device 2 is connected to the drowning detection alarm unit 1, and the drowning detection alarm unit 1 is connected to the drowning detection probe 4. The rigid collar 5 is provided with a safety lock 7 for adjusting the size of the collar. The drowning detection and alarm unit 1 is a sheath structure, and the drowning detection and alarm unit 1 is connected with sheath legs 3 . The gas generator 2 is connected to the drowning detection and alarm unit 1 with an elastic soft cable 6, and each component is connected to form a sealed waterproof body. The frame legs of the drowning detection and alarm unit 1 are supported and placed on the swimmer's head by means of the auricle and the alae of the nose, and a detection and alarm circuit powered by a battery is provided on the frame of the back of the head, and the circuit is normally open.

In the present invention, the gas generator 2 and the annular elastic air bag are placed in the groove of the lightweight rigid collar 5, the collar safety lock 7 is opened to adjust the size and the collar is put on the neck, and then the sheath type drowning detection and alarm unit 1 is worn. On the head, the drowning detection probe 4 leads to the nostril; when the swimmer enters the water, if the nostril is below the water surface, the two drowning detection probes 4 are short-circuited through the water, and the drowning detection alarm unit 1 is connected to the circuit and starts timing. When the value is fixed, it is identified as drowning, and now the gas generator 2 is started to work to generate gas to inflate the annular elastic air bag on the collar, and the alarm circuit is started simultaneously to report to the police in the form of sound and light. The drowning timing can be set by the user through the external self-locking button, such as 5 seconds, 10 seconds, 30 seconds, 50 seconds, 1 minute, 2 minutes, 5 minutes, etc. The shorter the time, the more sensitive the detection, the greater the probability of misjudgment, and the higher the safety index. At the same time, in order to improve the safety level, swimmers can wear a heartbeat smart bracelet on their wrists. When an abnormal heartbeat is detected (significantly higher than the average number of heartbeats during swimming), the smart bracelet will immediately send commands to the gas generator in the form of remote control. , to realize self-rescue by inflating the collar.

The drowning detection and alarm unit 1 can also be miniaturized and designed as a nose clip, and can communicate with the gas generator 2 on the rigid collar 5 in a wireless form, which is more convenient to wear and use.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various improvements made by the technical solution of the present invention are adopted, or directly applied to other occasions without improvement, all Within the protection scope of the present invention.
