Traditional fall detection systems mostly rely on external monitoring equipment, such as cameras and wearable sensors, but these methods are often limited by monitoring range, inconvenience of wearing and data accuracy. Especially for the daily activity monitoring of the elderly and people in specific occupations, it is necessary to ensure the immediacy and accuracy of the detection, as well as to ensure that the wearer is comfortable and does not affect normal life or work. Therefore, it is urgent to develop an integrated, high-precision and user-friendly fall detection device.

[0003] Some fall detection footwear products currently on the market have attempted to integrate sensors into shoes to monitor gait changes, but they generally have defects such as inaccurate sensor positioning and discomfort.

DETAILED DESCRIPTION

[0026] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, a test shoe for fall detection provided by an embodiment of the utility model comprises a sole layer 3, a cavity 34 is provided on the upper part of the sole layer 3, a palm pad device 2 is provided inside the cavity 34, an insole layer 1 is provided on the upper part of the palm pad device 2, an elastic upper layer 8 is provided on the upper part of the insole layer 1, an upper part of the elastic upper layer 8 is fixedly connected to an upper part 4 on the left side, a hook 43 is fixedly connected to the upper part 4, two first threading holes 42 are provided on the upper part 4, two second threading holes 31 are provided on the sole layer 3, the palm pad device 2 comprises a forefoot pad 21, the forefoot pad 21 is fixedly connected to a rear palm pad 22 through an elastic band, pressure sensors 23 are fixedly connected to the forefoot pad 21 and the rear palm pad 22 respectively, a control device 7 is fixedly connected to the upper left side of the sole layer 3, the rear part of the rear palm pad 22 is connected to a movable buckle 6 through an elastic rope 5, and the rear side of the upper part 4 is fixedly connected to the hook 43.

[0028] The test shoe for fall detection provided by the utility model can be used in the SREADI project.

[0029] STEADI, short for "Stopping Elderly Accidents, Deaths & Injuries", is a comprehensive program developed by the Centers for Disease Control and Prevention (CDC) to reduce the risk of falls and the injuries they can cause in people aged 65 and over. The program provides a range of tools and resources to help healthcare providers assess the risk of falls in older adults, implement personalized interventions, and educate patients and their families about ways to prevent falls.

[0030] By setting a cavity 34 on the upper part of the sole layer 3 and installing the palm pad device 2 therein, this design innovatively hides the pressure sensor 23, so that the pressure sensor 23 can be closer to the foot without affecting the wearing comfort, and accurately capture the changes in the sole pressure distribution. This design directly solves the technical problems that traditional external sensors are easily affected by external interference and have low detection accuracy, and improves the accuracy of fall event recognition.

[0031] The front sole pad 21 and the rear sole pad 22 are fixedly connected by an elastic band. This design simulates the natural bending of the foot when walking, ensuring that the pressure sensor 23 is in a stable position under different motion states, and data collection is continuous and reliable. This design not only improves the dynamic adaptability of the detection system, but also optimizes the user's natural foot feel when walking or running, avoiding the discomfort that may be caused by rigid structures, and embodies the application of ergonomic principles in smart wearable devices.

[0032] The design of the elastic upper layer 8 not only enhances the comfort of wearing, but also realizes the rapid adjustment of the space inside the shoe by cooperating with the two first threading holes 42 on the upper part 4 and the second threading hole 31 on the bottom layer 3, as well as the combination of the movable buckle 6 and the hook 43. This design breaks through the limitation of the fixed size of traditional footwear, allowing the user to adjust the tightness of the shoe according to the actual situation, improving the personalized adaptability of wearing, ensuring the continuity and effectiveness of the monitoring data, especially in long-term use, with the slight changes in the user's foot shape, it can still maintain a good fit.

[0033] The forefoot pad 21 is bonded to the bottom layer 3, the right side of the elastic upper layer 8 is sewn to the forefoot pad 21, two limit blocks 35 are fixedly connected to the middle of the cavity 34, and the forefoot pad 21 is fixedly connected to the rear foot pad 22 through an elastic band;

[0034] The setting of the limiting block 35 enables the rear palm pad 22 and the front palm pad 21 to be located on both sides of the limiting block 35 respectively, even after the elastic band is stretched or retracted.

[0035] A wire groove 32 is provided on the upper portion of the sole layer 3 , and a connector 33 is provided inside the wire groove 32 . The connector 33 is connected to the pressure sensor 23 through a wire.

[0036] The design of the wire groove 32 not only cleverly hides the connection line of the sensor, maintaining the simplicity and beauty of the shoe body, but also effectively prevents the risk of damage caused by exposed wires and improves durability. The built-in connector 33 further optimizes the internal layout and ensures the stability and safety of the electrical connection. This innovation avoids the complexity and inconvenience of traditional exposed wiring and solves the technical difficulties of electronic component integration and protection in wearable devices.

[0037] The upper portion 4 is provided with a charging port 41 and a switch.

[0038] This design simplifies the charging operation of the device. Users can charge the shoes directly without removing any parts, which greatly facilitates daily maintenance. The integration of the switch allows users to easily control the start and stop of the device, saving energy while giving users independent control over data collection. This is an effective improvement over traditional wearable devices that need to be frequently removed for charging and lack instant control functions.

[0039] The control device 7 is internally provided with a single chip microcomputer, a battery and Bluetooth.

[0040] The built-in single-chip microcomputer realizes the real-time processing and analysis of sensor data, improving the reaction speed and accuracy of data processing. The built-in battery design ensures the independent operation of the device, improving the portability and practicality of the wearable device. The integration of Bluetooth technology enables the shoe to wirelessly transmit data to smartphones or other receiving devices, facilitating remote monitoring and data analysis. This innovation solves the problem of convenience and immediacy of data transmission, and is a key step towards smart connected wearable devices.

[0041] The movable buckle 6 is provided with a plurality of buttonholes, and a size mark is provided on the right side of the buttonhole. The size mark is not shown in the figure. There should be a number as a mark on the right side of the buttonhole to indicate a specific shoe size.

[0042] The buttonholes and size markings on the movable buckle 6 provide a simple way to adjust the size. Users can adjust the tightness of the shoes according to their own needs to achieve personalized fit and improve wearing comfort and flexibility. This design solves the problem that standard sizes are difficult to meet the differences in foot shapes of all people, and reflects the careful consideration of users' personalized needs.

[0043] A front filling seam 82 and two side filling seams 81 are formed on the elastic upper layer 8 , and the interiors of the front filling seam 82 and the side filling seams 81 are filled with soft pads 9 , respectively.

[0044] The design of the soft padding 9 inside the front filling seam 82 and the side filling seam 81 not only enhances the comfort and support of the upper, but also optimizes the pressure distribution according to the ergonomic principles, reduces the sense of oppression that may be caused by long-term wear, and improves the overall wearing experience. This design is aimed at the special application scenario of fall detection equipment, effectively alleviates the discomfort of the wearer during activities, and reflects the deep concern for user comfort.

[0045] like Figures 5 to 7 As shown, a test component provided by an embodiment of the utility model includes a test shoe for fall detection, and also includes a first upper arm strap 13 and a second upper arm strap 14, the first upper arm strap 13 and the second upper arm strap 14 are respectively fixedly connected with an upper arm posture sensor module 15, and also includes a first upper body strap 16 and a second upper body strap 18, the rear part of the first upper body strap 16 is fixedly connected with an upper back pad 17, the rear part of the second upper body strap 18 is fixedly connected with a lower back pad 19, the upper back pad 17 and the lower back pad 19 are respectively fixedly connected with a spine posture sensor module, and also includes a thigh strap 10 and a calf strap 11, and the thigh strap 10 and the calf strap 11 are respectively installed with a leg posture sensor module 12.

[0046] In the test components of the utility model, in addition to the core fall detection test shoes, a series of additional physiological posture sensor modules are creatively introduced. The addition of these components is aimed at building an all-round, multi-dimensional human body dynamic monitoring system to achieve a comprehensive assessment of fall risks and in-depth research on sports biomechanics.

[0047] By fixing the upper arm posture sensor module 15 on the first upper arm strap 13 and the second upper arm strap 14, the dynamic changes of the upper limbs can be accurately captured, which is crucial for evaluating the imbalance state at the moment of falling. This design goes beyond the limitation of traditional fall detection equipment that only focuses on the lower limbs. By comprehensively analyzing the swing pattern of the upper limbs, abnormal posture changes before falling can be identified earlier, thereby triggering an alarm in advance and improving intervention efficiency.

[0048] The spine posture sensor modules installed on the upper back pad 17 of the first upper body strap 16 and the lower back pad 19 of the second upper body strap 18 are important innovations for monitoring the core stability of the human body. These sensors can evaluate the body's ability to shift its center of gravity and maintain balance by monitoring the changes in the spine's posture, which is of great significance for preventing falls. This design not only helps to understand the mechanical mechanism of falls, but also provides a scientific basis for rehabilitation training and posture correction.

[0049] The leg posture sensor module 12 installed on the thigh strap 10 and the calf strap 11 further improves the whole body dynamic monitoring network. As the main limbs that support and propel the body, the legs play a decisive role when a fall occurs. By continuously monitoring the angle changes of the leg joints and the distribution of muscle strength, walking stability can be evaluated in real time, and gait abnormalities that may cause falls can be discovered in time, which has a significant effect on preventing falls and improving gait training strategies.

[0050] When in use, the fall detection test shoe and the test assembly of the utility model work together through the following steps to achieve efficient and accurate fall monitoring and human body dynamic analysis:

[0051] First, the user activates the system through the switch on the upper part 4, and the single chip microcomputer in the control device 7 starts to run, while the Bluetooth module is on standby, ready to communicate data with external devices. The built-in battery of the shoe provides power support for the system.

[0052] When the user walks or exercises in the test shoe, the pressure sensors 23 on the forefoot pad 21 and the rear foot pad 22 of the sole monitor the changes in the pressure distribution of the sole in real time. These sensors are connected to the wires in the wire slot 32 through the connector 33, ensuring the stable transmission of the signal to the control device 7 for preliminary processing.

[0053] At the same time, the first upper arm strap 13 and the second upper arm strap 14 worn on the upper arm, the first upper body strap 16 and the second upper body strap 18 on the upper body, and the posture sensor modules on the thigh strap 10 and the calf strap 11 synchronously record the movement posture of the upper limbs, trunk and lower limbs, including the stability of the spine and the dynamic changes of the leg joints, and capture the body posture abnormalities before falling in all directions. The posture sensor module can communicate with the control device 7 via the built-in Bluetooth.

[0054] The single-chip microcomputer in the control device 7 conducts a comprehensive analysis of the collected multi-source data and uses a preset algorithm to identify behavioral patterns that may indicate a fall, such as signs of unsteady steps and body imbalance. This process is fast and accurate, thanks to the algorithm's in-depth learning and understanding of gait characteristics.

[0055] The user can adjust the tightness of the shoe through the eyelet of the movable buckle 6, and the size marking ensures consistency and convenience of each adjustment. The filling seam design and the soft pad 9 of the elastic upper layer 8 improve the wearing comfort, ensuring that the user can still feel comfortable and free of burden during long-term monitoring.

[0056] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
