[0066] The fall protection device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0067] Reference Figures 1 to 6 As shown, the fall protection device provided according to an embodiment of the present invention includes an inflatable protective belt 10, an air pump 20 and a control component 30.

[0068] Specifically, the inflatable support belt 10 is suitable for being worn on the waist of a user and surrounding the buttocks of the user, and the inflatable support belt 10 has an inflation port 1011a. The air pump 20 is arranged on the inflatable support belt 10, and the air outlet of the air pump 20 is connected to the inflation port 1011a of the inflatable support belt 10. The control component 30 is arranged on the inflatable support belt 10, so that the user can operate and control the air pump 20 to inflate the inflatable support belt 10.

[0069] That is, the inflatable support belt 10 can be wrapped around the waist of the user, and the inflatable support belt 10 has a relatively wide width (dimensions in the vertical direction) and can cover the buttocks of the user. In addition, the inflatable support belt 10 has an inflation cavity and an inflation port 1011a, and the inflation port 1011a is connected to the air outlet of the air pump 20. When the air pump 20 is working, the air outlet of the air pump 20 can inflate the inflation port 1011a, and the gas enters the inflation cavity through the inflation port 1011a, thereby inflating the inflatable support belt 10. The control component 30 can be operated by the user to control the start or stop of the air pump 20, thereby realizing the control of the inflation of the inflatable support belt 10.

[0070] As a medical worker, the inventor found in actual work that among the elderly patients admitted, some elderly patients often slipped and fell when getting up from the bed to go to the toilet or move around, resulting in falls and fractures. Moreover, these patients often fell on the buttocks or hips, which may cause fractures of the lumbar spine and hips.

[0071] Therefore, by proposing the fall protection device of the present application, it is intended to help the elderly to protect themselves from falls to a certain extent. When using the fall protection device of the present invention, the inflatable protective belt 10 can be worn on the waist of the user and adjusted to wrap around the user's hips. Since the user is prone to fall when moving, the user can operate the control component 30 to control the air pump 20 to inflate the inflatable protective belt 10 before the activity, so that the inflatable protective belt 10 expands. Therefore, in the event of an accidental slip, since the inflatable protective belt 10 is wrapped around the user's hips and is in an expanded state, the expanded inflatable protective belt 10 can play a buffering and protective role for the user.

[0072] According to the fall protection device provided by the embodiment of the present invention, the inflatable protective belt 10 can be worn around the waist and wrapped around the buttocks. When the user needs (for example, during activities), the user can control the air pump 20 through the control component 30 to inflate the inflatable protective belt 10, so that the inflatable protective belt 10 remains in an expanded state after being inflated. If the user falls, the inflatable protective belt 10 in the expanded state can provide buffering protection for the user, thereby reducing the risk of fractures and strokes after the user falls to a certain extent. The structure is simple and easy to use and wear.

[0073] It can be understood that the inflatable belt 10 is also provided with an air release valve 50, which can be a manual valve or an electrically controlled valve. The manual valve can be manually operated by the user and can be opened or closed manually, while the automatic valve can be controlled to open or close by the control component 30. During use, if the user no longer needs the protection provided by the inflatable belt 10, the air release valve 50 can be opened to discharge the gas in the inflatable belt 10, thereby restoring the inflatable belt 10 to its original state, so that the user is no longer affected by the inconvenience or bad feeling brought by the expanded inflatable belt 10. In addition, it is also convenient for the user to remove and store the inflatable belt 10.

[0074] Reference Figure 1 to Figure 2 As shown, in one embodiment of the present invention, the inflatable belt 10 comprises a surrounding covering portion 101, a first strap portion 102 and a second strap portion 103, wherein the surrounding covering portion 101 is suitable for surrounding and covering the buttocks of the user, and the inflation port 1011a is provided in the surrounding covering portion 101 to inflate the surrounding covering portion 101. The first strap portion 102 is connected to one end of the surrounding covering portion 101; the second strap portion 103 is connected to the other end of the surrounding covering portion 101, and the second strap portion 103 is suitable for being detachably connected to the first strap portion 102.

[0075] That is to say, the surrounding covering portion 101 can be wrapped around the user's buttocks to protect the user's buttocks, and the first strap portion 102 and the second strap portion 103 are respectively connected to the two ends of the surrounding covering portion 101. When in use, after the surrounding covering portion 101 is wrapped around the user's buttocks, the first strap portion 102 and the second strap portion 103 can be detachably connected together, and then the surrounding covering portion 101 can be fixed to the user using the first strap portion 102 and the second strap portion 103, so that it is convenient for the user to use and wear it.

[0076] Advantageously, Velcro is provided on the first strap portion 102 and the second strap portion 103 respectively. By bonding the Velcro on the first strap portion 102 to the Velcro on the second strap portion 103, on the one hand, quick donning or removal can be achieved. On the other hand, by bonding the first strap portion 102 and the second strap portion 103 at different positions, the tightness of the detachable belt around the user's waist can be adjusted, and the detachable belt can be adapted to users of different weights and body shapes.

[0077] More advantageously, the control assembly 30 and the air pump 20 are disposed on the first strap portion 102 or the second strap portion 103. Since the first strap portion 102 and the second strap portion 103 are generally located on the front side of the adapter, disposing the control assembly 30 and the air pump 20 on the first strap portion 102 or the second strap portion 103 is convenient for user operation and installation.

[0078] Reference Figures 3 to 5 As shown, in some embodiments of the present invention, the surrounding covering portion 101 includes an inner bag 1011 and an outer elastic restraint sleeve 1012, the inner bag 1011 is formed into a flat ring structure when inflated, the inflation port 1011a is provided on the inner bag 1011, and the outer elastic restraint sleeve 1012 is covered on the outside of the inner bag 1011.

[0079] That is to say, the inner capsule 1011 is constructed into a flat ring structure. Before being inflated, the inner capsule 1011 can be compressed into a deflated capsule body, and after being inflated, the airbag expands to restore the flat ring structure. This flat ring structure after expansion can make the inflatable belt 10 have a large contact area with the ground when falling and touching the ground, and has a good buffering effect. In addition, it can protect the user's body stability and prevent the inner capsule 1011 from being inflated into a spherical shape, which can easily cause body instability, such as rolling, and cause other injuries to the user. The outer elastic binding sleeve 1012 is elastic. After being coated on the outside of the inner capsule 1011, it can not only protect the inner capsule 1011, but also use the elastic contraction force of the outer elastic binding sleeve 1012 when the deflation valve is opened to force the gas in the inner capsule 1011 to be discharged more smoothly and fully.

[0080] Optionally, the inner capsule 1011 is made of PVC, silicone or nylon material, and the outer elastic restraint sleeve 1012 is made of elastic cloth, wherein the PVC, silicone or nylon material facilitates the inner capsule 1011 to be constructed into a flat ring structure and can expand after inflation, while the elastic cloth has good wrapping properties and provides elastic contraction force, which facilitates the discharge of gas in the inner capsule 1011.

[0081] Reference Figure 1 to Figure 2 and Figure 6As shown, in one embodiment of the present invention, the control component 30 includes a button 301 and a controller 302, wherein the button 301 is used for user operation; the controller 302 is connected to the air pump 20 and the button 301, and is used to control the air pump 20 to turn on or off according to the trigger signal of the button 301.

[0082] During use, if the user needs to inflate the inflatable belt 10, he only needs to press the button 301. The trigger signal of the button 301 is sent to the controller 302, and the controller 302 can control the air pump 20 to start according to the trigger signal. In this way, through the control of the button 301, it is convenient for the user to control the inflation, and the operation is simple.

[0083] It is understandable that the control component 30 further includes a power module 303 , which is located in the controller 302 and supplies power to the air pump 20 , and the power module 303 may be a rechargeable battery.

[0084] Reference Figure 6 As shown, in some embodiments of the present invention, a gravity sensor 40 and a wireless communication module 41 are also included. The gravity sensor 40 is connected to the controller 302 to detect gravity acceleration; the wireless communication module 41 is connected to the controller 302; the controller 302 is also used to control the wireless communication module 41 to send an alarm signal to a remote monitoring terminal according to the detected gravity acceleration.

[0085] That is, the gravity sensor 40 can be used to detect the gravity acceleration of the inflatable support belt 10, and the wireless communication module 41 can be used to establish communication with a remote monitoring terminal. When the user wears the inflatable support belt 10, if the user falls during outdoor activities, the gravity acceleration detected by the gravity sensor 40 is greater than the set value, indicating that the user may have a fall problem, and the controller 302 can control the wireless communication module 41 to send an alarm signal to the remote monitoring terminal, which can be a mobile terminal such as a smart phone carried by a family member or other guardian. When the mobile terminal receives the alarm signal, the family member or guardian can be informed that the user has a fall problem, so that the family member or guardian can take rescue measures in time.

[0086] Optionally, the wireless communication module 41 can be a GSM module, a WIFI module, a Bluetooth module, etc. When it is a Bluetooth module, the Bluetooth module can establish a communication connection with the user's mobile phone, etc., first send the alarm signal and GPS location information to the mobile phone, and then send it to the remote monitoring end through the mobile phone.

[0087] Advantageously, it further comprises a GPS positioning module 42 , which is connected to the controller 302 to obtain GPS location information and send it to the monitoring end through the wireless communication module 41 .

[0088] That is to say, the GPS location information of the user can be obtained through the GPS positioning module 42. Specifically, when the gravity sensor 40 detects that the user has fallen, the controller 302 controls the wireless communication module 41 to send an alarm signal, and at the same time, the obtained GPS location information is also sent to the remote monitoring end, so that the user's family or guardian can understand the location where the user has fallen, thereby facilitating rescue.

[0089] Reference Figure 2 and Figure 6 As shown, in one embodiment of the present invention, it also includes a camera 43 and a memory 44, wherein the camera 43 is connected to the controller 302, and the camera 43 is arranged on the first strap portion 102 or the second strap portion 103; the memory 44 is connected to the controller 302; the controller 302 is also used to control the camera 43 to start recording according to the detected gravity acceleration, so as to record the surrounding environment video data and save it in the memory 44.

[0090] That is, during outdoor activities, after the gravity sensor 40 detects that the user has fallen, the controller 302 can control the camera 43 to immediately start recording, record the video data of the user's surrounding environment, and save it in the memory 44. Since the user is an elderly person, it is difficult for family members or guardians to rush to the scene in time after the fall, and the rescue time is usually urgent. As a passerby, you may be questioned during the rescue process, which also causes some passersby to be afraid to rescue.

[0091] In this embodiment, based on the above factors, after the user falls, the camera 43 can be activated to collect video images of the surrounding environment, and the process of rescue by passers-by can also be recorded in it. In this way, family members or guardians can restore the scene by querying the video, so as to eliminate misunderstandings between the two parties and other problems, which is conducive to the user obtaining timely assistance from passers-by after the fall.

[0092] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
