Patent document CN209814233U discloses a life-saving bracelet. When drowning danger does not occur, the air bag is in a folding state, so that the wearing comfort of a user is improved. Once danger occurs, a user can manually rotate the switch to puncture the gas tank, and the gas bag is inflated and popped out to provide buoyancy to ensure the safety of the user. The safety control device has the disadvantages that when drowning danger occurs, a user is always in a confused state, and the switch is difficult to accurately trigger in time to enable the air bag to pop out for safety guarantee. The other type of inflatable life-saving bracelet in the prior art only takes the heart rate, blood oxygen and other personalized parameters of a user as the trigger threshold of a dangerous signal, and cannot well guarantee the safety of the user when the drowning risk occurs. If patent document CN110371275A discloses an automatic prevent drowned lifesaving bracelet, through real-time detection user's rhythm of the heart and blood oxygen value, drive the vibration motor under the dangerous condition of user rhythm of the heart blood oxygen numerical value of monitoring, make the bracelet vibration warn the user, user's no response in the specified time, then puncture the gas pitcher by well accuse chip control motor, the gasbag pops out and provides buoyancy guarantee user safety. The method has the defects that when drowning risks occur to different users, the physiological heart rate and blood oxygen change of the users have great randomness and difference, and the threshold value used for judging the dangers is unreasonable, so that the safety of the users cannot be well guaranteed when the drowning risks occur.

Specific embodiments of the present invention are further described below.

The airbag type drowning-preventing life-saving device of the specific embodiment adopts a wearable arm sleeve (or called oversleeve and armguard), has the advantages of safety and comfort, and is structurally shown in fig. 1 a. The lower half part in the airbag box 8 mainly comprises a sensor and a central processing unit module, the upper half part mainly comprises a power supply and an airbag group module, and the specific position structure and the air guide mode of the airbag are shown in fig. 2 and 3. The detailed structure of which triggers the gas guide is shown in figures 4 and 5.

In some embodiments, the main material of the arm sleeve 9 is made of foam rubber, and the arm sleeve has certain extensibility and skin-adhering property, so that the wearing experience is improved.

In some embodiments, the heart rate blood oxygen sensor 1 is arranged at the inner side of the arm sleeve 9 corresponding to the wrist, and can be directly contacted with the skin of the wrist, so that the measurement accuracy is improved.

In some embodiments, the water pressure sensor 5 is located on the bottom outer wall of the airbag case 8 for detecting the relative pressure of the environment in which the user is located.

In some embodiments, the vibration alarm 2 is arranged on the outside of the arm sleeve 9 corresponding to the wrist, in conformity with the habit of wearing a watch by the user, facilitating the user's management when giving false-alarm vibrations.

In some embodiments, the central processor 3 determines whether the user is in a dangerous state by analyzing the values detected by the heart rate blood oxygen sensor and the water pressure sensor.

In some embodiments, the arm sleeve 9 is further provided with a GPS module 4, and when the user drowns, the rescuer can accurately locate in time the person to be rescued by the positioning information provided by the GPS module 4.

In some embodiments, the manual trigger switch 7 is located on the side wall of the airbag box 8, when a user needs to trigger, the user can press the manual trigger switch 7 on the side wall of the airbag box 8 with the palm, the manual trigger switch 7 has a large area, so that the force of the user's palm can be well transmitted, a large impact force is generated on the manual striker 16, and the air tank 6 can be conveniently punctured.

In some embodiments, manual striker 16 and electric striker 12 share a trigger air guide 14, which is distributed on both sides of the air tank port as an air release. Due to the design, the introduction of a plurality of trigger air guide parts caused by different manual and electric trigger conditions is avoided, and the volume of the air bag box is reduced.

When drowning danger occurs, if a user is in an intelligent state, the manual firing pin can be driven to break the side wall of the air tank opening by pressing the manual trigger switch, so that the air bag is filled with air to achieve the aim of lifesaving.

When drowning danger occurs, if the heart rate value of a user exceeds 60-150 times/minute or the blood oxygen value is lower than the normal range of 90%, the central processing unit reminds the user that the user is possibly in a dangerous state at the moment, if the user does not turn off the alarm in time, the motor drives the electric firing pin to advance along the screw rod direction, and the electric firing pin breaks through the side wall of the gas tank, so that the gas is filled in the gas bag to achieve the lifesaving purpose.

When drowning danger takes place, if the relative water pressure of user position department reaches 10000N, central processing unit reminds the user probably to be in dangerous state this moment, if the user does not close the alarm in time, the motor can drive electronic striker and advance along the screw rod direction, and electronic striker bumps the gas pitcher lateral wall, makes gas full of the gasbag and reaches the lifesaving purpose.

When the air tank is punctured, high-pressure air in the air tank enters the air bag along the air guide opening in the trigger air guide part, so that the air bag is inflated and ejected. The triggering air guide part is a sealing piece and is connected with the air bag through threads, and high-pressure air rotates for 90 degrees along the air guide pipe to inflate the air bag at the upper part after coming out of the air tank opening.

In some embodiments, the entire airbag housing portion contains components such as a battery, a motor, and an airbag, with the power source portion placed in the sealed and waterproof chamber and the airbag placed in the open chamber for inflation and ejection. In some embodiments, the air bag box is divided into an upper chamber and a lower chamber, the lower chamber is completely sealed, the power supply and components needing power supply are placed in the lower chamber, and the upper chamber is only fixedly placed with the air bag through the magic tape.

In some embodiments, the airbag is folded when not ejected during normal use, and as shown in fig. 3, the outer wall of the airbag includes a top cover, the size of which matches the size of the airbag box, and after the airbag is folded and placed on the upper layer of the airbag box, the top cover can be adhered to the wall of the airbag box through magic. Through the structure, the occupied space of the airbag is reduced when the airbag is not popped up, and meanwhile, the airbag can be successfully popped up when inflated.

The whole product of the embodiment can be repeatedly used, and the gas tank can be replaced after each triggering to be used again.

In some embodiments, the lifesaving armguard is made of foam rubber, wears in the oversleeve form, has light comfortable advantage when not taking place danger, provides better use experience for the water sports user. Once drowning danger occurs, the user can manually pop out the air bag if in an intelligent state; if the user is in a panic state, the system pops out the air bag when monitoring that the heart rate or the blood oxygen value of the user exceeds a threshold value; if the user has fallen into the water, the system detects that the user's water pressure exceeds a threshold value and pops up the air bag. Different trigger scenes are comprehensively considered, different trigger mechanisms are used, and safety of water sports personnel is guaranteed in an all-round mode. Generally speaking, this gasbag formula prevents drowned life saving equipment compares with traditional life saving equipment, adopts multichannel safety protection mechanism safe and reliable more, and the oversleeve type is worn also more comfortablely and more portable.

Three life-saving lines and a specific working flow provided by the air bag type drowning-preventing life-saving device of the embodiment are described below, and are shown in fig. 6.

A first line of defense: and (4) manually triggering. Once a user finds that drowning risks occur, if the user has the ability to take certain actions, the user can squeeze the manual switch of the side wall of the air bag with the palm, at the moment, large impact force is transmitted to the manual striker through the manual switch, the striker breaks the air tank through impacting the side wall of the air tank opening, high-pressure air in the air tank enters the trigger air guide part through the air tank opening, and the air flowing direction in the device is turned by 90 degrees to inflate the air bag on the upper side. The gasbag aerifys back pressure grow, connects the magic of gasbag and gasbag box and pastes the separation, and the gasbag pops out to produce buoyancy and ensures user's safety.

And (3) second defense line: triggering a psychological blood oxygen threshold. When drowning danger takes place, the user often hardly keeps the reason wisely to trigger manual switch, and the device just can get into the second line of defence this moment. Because the psychology of the user is nervous when the drowning danger occurs, the heart rate and the blood oxygen value are reflected on the physiological parameters and often have larger fluctuation. We set the normal heart rate range between 60-150 beats/minute, the normal blood oxygen value is higher than 90%, the heart rate and the blood oxygen value of the user are detected in real time through the heart rate blood oxygen sensor positioned on the inner side of the wrist part, once the central control chip detects that the heart rate or the blood oxygen value of the user exceeds a specified threshold value, the vibration alarm positioned on the outer side of the wrist part can send vibration to remind the user, if the user thinks that the state is normal, the alarm can be closed within 6s, the early warning system can be dormant for 30s and then continues to detect the heart rate and the blood oxygen value of the user, if the user is in a dangerous state and cannot close the alarm, the central control chip drives the motor, the motor drives the electric firing pin to move forwards by rotating the screw rod until the side wall of the air tank opening is punctured, high-pressure air in the air tank enters the trigger air guide part through the air tank opening at the moment, and the air flowing direction in the device is turned by 90 degrees to inflate the air bag on the upper side. The gasbag aerifys back pressure grow, connects the magic of gasbag and gasbag box and pastes the separation, and the gasbag pops out to produce buoyancy and ensures user's safety.

The third defense line: and triggering a water pressure threshold. When drowning danger occurs, although the heart rate and the blood oxygen value of a user are detected to be used as a second line of defense triggering, the physiological reactions of different users in a stress state are different, so that the objectivity exists only by using the heart rate and the blood oxygen parameters, and a more objective water pressure threshold value is selected to be used as a third line of defense triggering. When the set water pressure reaches 10000N, the user is judged to be possibly in a dangerous state. The relative pressure of the real-time position of the user is detected through the water pressure sensor located on the outer side of the bottom of the air bag box, if the relative pressure detected by the central control chip exceeds a threshold value, the vibration alarm located on the outer side of the wrist can send vibration to remind the user, if the user considers that the state of the user is normal, the alarm can be closed within 6s, and the early warning system can be dormant for 30s and then continues to detect the real-time water pressure of the position of the user. If the user is in a dangerous state and cannot close the alarm, the central control chip drives the motor, the motor drives the electric firing pin to move forwards by rotating the screw rod until the side wall of the air tank opening is punctured, high-pressure air in the air tank enters the trigger air guide part through the air tank opening at the moment, and the air flowing direction in the device is turned by 90 degrees to inflate the air bag on the upper side. The gasbag aerifys back pressure grow, connects the magic of gasbag and gasbag box and pastes the separation, and the gasbag pops out to produce buoyancy and ensures user's safety.
