Description

Fall protection system and protection method thereof

Technical Field

The invention relates to the technical field of protection devices, in particular to a fall protection system and a protection method thereof.

Background

The senile people have hip fracture caused by falling down accidentally during walking due to the reduction of leg muscle strength, and falling down becomes one of the inducement of hospitalization of the elderly. In fact, it is estimated that falls are one of three causes of death in the elderly. Falls are defined as sudden, uncontrolled and unintended downward displacement of the body to the ground, followed by an impact, after which the body remains resting on the ground.

Fall detection systems are systems for providing fall protection, which can be used to process the output of one or more mobile sensors to determine whether a user has suffered a fall. Most existing body worn fall detection systems commonly make use of accelerometers (typically accelerometers that measure acceleration in three dimensions), and they are configured to infer the occurrence of a fall by processing the time series generated by the accelerometers. In addition, some fall detection systems may also utilize an air pressure sensor to measure the height or absolute altitude of the fall detection system, etc.

In addition, the existing fall protection system for the old generally has two types of passive protection and active protection, wherein the passive protection device is a wearable lining which is often made of sponge, rubber or foam materials, the whole structure is relatively bulky, the old cannot be closely attached to a human body, the comfort is relatively poor, the old can fall down to influence normal activities after wearing, and the trouble is caused to daily life; the active protection device is an air bag type protection device worn on the waist and buttocks of the old at present, and can automatically pop up the air bag when the old is sensed to fall, and the system controls the electric steering engine to puncture the bottle mouth of the air bottle to enable the air bag to be inflated rapidly, so that the hip is protected.

CN113287805a discloses a wearable fall protection system, which comprises a waistband, wherein the end part of the waistband is provided with buckles matched with each other, and the waistband is used for wearing the waistband on the waist of a human body; the inflatable air bag is arranged on the waistband, and an air inlet of the inflatable air bag is connected with the rapid inflation device through an air duct; the falling detection module is used for detecting motion information of a user, judging whether the user falls according to the motion information, and sending a trigger signal to the control device; the gas cylinder is used for storing gas; the triggering device is used for triggering the gas cylinder to be opened so as to realize the inflation of the inflatable air bag; and the control device is used for controlling the triggering device to be started according to the triggering signal, and is connected with the falling detection module and the triggering device.

The fall protection system based on the airbag inflation principle can play an effective protection function only by inflation, and the airbag inflation mode mainly comprises three modes, namely, chemical reaction generation of a large amount of gas, storage of high-compression gas and pumping of external gas. The three inflation modes have certain limitations in the aspect of falling protection, and for falling protection, the requirement on portability is high because a user is required to wear the protection device for a long time, and the three inflation modes all require to provide an additional gas supply device for inflating the air bag, so that the load of the user is increased; furthermore, the falling direction of the user is uncontrollable, so the protection range of the protection device should be comprehensive. The wider the coverage area of the airbag, the longer it takes to fill, and the greater the amount of fill gas required, the greater the burden on the user; in addition, the mechanical structure is complex, the possibility of mechanical failure exists, and the use reliability of the protection device is reduced; when the high-pressure air source is worn for a long time, the high-pressure air bottle has explosion risk once encountering heat, and extra injury is easily caused to a human body.

Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present invention.

Example 1

Referring to fig. 1, the present invention provides a fall protection system, which may comprise:

a wearable guard structure 200 configured to be attached to a user's guard site and including a plurality of adjustable elastic cushioning regions corresponding to the user's guard site.

A detection module 100 for obtaining at least one item of fall process information associated in time with the user;

the control module 300 is configured to determine a fall type of the user according to the fall process information, and control a protection state change of the corresponding elastic buffer area based on the fall type.

According to a preferred embodiment, the detection module 100 (or fall detection module) is adapted to obtain fall process information relating to the fall status of the user, to allow a processor (such as the control module 300) to determine whether the user has fallen, and the user-specific fall type, in response to the fall process information. Specifically, the falling process information acquired by the detection module 100 may include acceleration, angular velocity, and inclination angle of the user in the X-axis, Y-axis, and Z-axis, a distance between the user and the falling ground, a pressure of the user on the ground, physiological information of the user, and the like. In particular, as shown in fig. 1, the detection module 100 may be designed to be worn on a wrist of a user. Preferably, as a non-limiting example, the wrist-worn detection module 100 may be configured in the form of a wristband, bracelet, or wristwatch, or the like. It should be understood that the invention is not so limited and that the detection module 100 can alternatively be designed to be worn on any or all of the user's waist, chest or back, or be configured as a pendant near the user's neck.

According to a preferred embodiment, referring to fig. 7, the detection module 100 may include one or more of a ranging sensor, an accelerometer, and a barometric pressure sensor. In particular, the ranging sensor may use acoustic or light waves to measure the distance to ground by measuring the time between the issuance of an acoustic or optical pulse and the echo, and based on the known velocity of the acoustic or optical pulse in a particular medium. Further, alternatively, the ranging sensor can also estimate the distance to the target by measuring a change in capacitance or inductance. Alternatively, the distance to the target is determined by measuring the change in light intensity. In particular, the ranging sensor may output the measured distance to a processor (e.g., control module 300) which may determine whether the user has fallen by comparing it to a threshold.

According to a preferred embodiment, the accelerations respectively detect acceleration in the directions of the orthogonal triaxial (X, Y, Z) and angular velocity about the orthogonal triaxial (X, Y, Z) and output a measured attitude signal containing the acceleration and the angular velocity. Specifically, the accelerometer may be constituted by a triaxial acceleration sensor that detects acceleration of the orthogonal triaxial (X, Y, Z), a triaxial gyro sensor that detects angular velocity (rotation speed) of the orthogonal triaxial (X, Y, Z), and a triaxial electronic compass that detects magnetic field strength of the orthogonal triaxial (X, Y, Z). In addition, the detection module 100 may further include an electronic compass that detects an absolute direction by detecting geomagnetic field intensity for the orthogonal triaxial (X, Y, Z). The electronic compass outputs a measured posture signal including the detected magnetic field strength (or an absolute direction determined from the magnetic field strength).

According to a preferred embodiment, the air pressure sensor may be used to measure pressure changes due to changes in body posture (e.g. height) when the user falls. For example, the moment the user falls on the ground, the impact pressure generated by the user's elbow or hip against the ground. Alternatively, an air pressure sensor may be used to detect ambient air pressure.

Further, in some embodiments, the detection module 100 may further include several physiological information acquisition modules, such as a heart rate sensor, a blood pressure sensor, and the like. Specifically, the physiological information acquisition module can acquire a plurality of physiological characteristic data, such as heart rate, blood pressure and the like, in the travelling process of the user, particularly in the falling process. Generally, as the physical posture of a user changes, for example, the physiological information such as the heart rate and the blood pressure of the user changes unexpectedly, the physiological state of the user can be determined according to the data such as the heart rate and the blood pressure, and therefore, whether the user falls or not can be known according to the trend of the physiological state information of the user over time.

According to a preferred embodiment, in addition to configuring at least one detection module 100 in a wearable form, detection modules 100 containing the above-described data collectors (such as ranging sensors, accelerometers, and barometric pressure sensors) may alternatively be attached to various parts of the user's body, respectively, to increase the reliability of data detection. Alternatively, when a plurality of detection modules 100 are configured, each detection module 100 may be attached and fixed to a predetermined guard site of the user together with the wearable guard structure 200.

According to a preferred embodiment, referring to fig. 7, the control module 300 may include a transceiver circuit, a processing unit, and a storage unit. In particular, for example for a ranging sensor, the transceiving circuit may comprise a transmitter and a receiver, wherein the transmitter emits pulses of sound or light, and the receiver may measure reflected echo signals generated by the arrival of these pulses of sound or light at the target surface. The processing unit is configured to calculate a fall state of the user based on detection data obtained by the detection module 100, such as a ranging sensor, an accelerometer, and a barometric sensor. The storage unit is signally connected to the processing unit, which is arranged to store detection data from the detection module 100, results of processing or pre-processing of the detection data, and/or computer instructions to allow the processing unit to execute fall detection algorithms and/or to otherwise control the operation of the fall detection system. It will be appreciated that the storage unit may also use the transceiver circuitry to upload the detection data to a remote server for storage. The control module 300 may be a processor of a remote control terminal or a processor for controlling the guard structure 200.

According to a preferred embodiment, the technology of determining whether the user falls down by using the information such as the acceleration data, the distance data, the pressure data, the physiological characteristic data and the like is mature, and the specific calculation mode is not limited in the invention. As a non-limiting example, a specific example of determining the falling state of the user by using the information such as acceleration data, distance data, pressure data and physiological characteristic data may be to perform recognition processing on the data information by using a deep learning algorithm, recognize and classify the data based on the deep learning algorithm, determine different falling types for different users according to the limb movement characteristics and physiological information of the different users, and provide falling judgment and protection measures more conforming to personal characteristics for the users. In particular, different fall types have differences in fall attitudes (such as acceleration, angular velocity, and inclination of the user when falling), ground distances (such as the distance between the wrist and the ground when falling), and ground pressures.

According to a preferred embodiment, referring to fig. 1 to 4, the present embodiment provides a protective structure 200 configured to be attached and secured in a wearable manner to a fall protection site of a user. For example, the protective structure 200 may be worn on any or all of the user's elbows, knees, waist, buttocks, and head, and is not limited thereto. Further, the protective structure 200 may be built in the user's clothing or worn separately, which is not particularly limited by the present invention.

According to a preferred embodiment, referring to fig. 2, the guard structure 200 may include a base layer 220 and one or more adjustable buffer portions 210 formed on a surface of the base layer 220. Specifically, the base layer 220 may be made of a flexible material. The plurality of buffer portions 210 are spaced apart from the surface of the base layer 220. Further, the base layer 220 corresponding to different wearing parts of the user may have different shapes to adapt to the characteristics of the different wearing parts. In particular, the material, shape and size of the base layer 220 are not particularly limited in the present invention.

According to a preferred embodiment, as shown in fig. 2 to 4, the buffer 210 may include a fixing member 201, a locking member 202, a pressing member 203, and a buffer 204. Specifically, taking fig. 2 and 3 as an example, the surface of the base layer 220 is concavely provided with a plurality of grooves having a substantially rectangular cross-sectional shape, and each groove is correspondingly filled with the buffer member 204. In particular, the cushioning member 204 may be made of a memory material, such as a memory sponge. Specifically, the cushioning member 204 may be formed by pressing a memory sponge of a certain thickness into a compressed state of a smaller thickness, and may be pre-tensioned by pressing the sheet-like or block-like pressing member 203 so as to accumulate a protective force. As shown in fig. 4, when the pressure of the pressing member 203 is removed, the cushioning member 204 is quickly restored to the original thickness, thereby protecting the user from falling.

According to a preferred embodiment, as shown in fig. 2 and 3, the surface of the cushioning member 204 is provided with a pressing member 203. The press 203 is used for pretensioning of the buffer 204 in the inactive state. In particular, in the present invention, a special case of the pressing member 203 may be a memory metal material. Further, in the inactive or non-use state, the pressing member 203 may be fixed to the surface of the buffering member 204 by the fixing member 201 and the locking member 202 provided at both ends thereof. Specifically, as shown in fig. 3, the pressing member 203 has one end connected to the fixing member 201 and the other end movably connected to the locking member 202.

According to a preferred embodiment, the locking element 202 may comprise a catch and a trigger. The triggering member may employ electrical, magnetic and/or optical excitation means. Each trigger may be connected to the control module 300 by a wire. In particular, the card slot may be made of a memory material. For ease of understanding, a specific example of releasing the compression member 203 by the trigger to activate the cushioning member 204 may be, by way of non-limiting example: one part of the clamping groove is arranged on the surface of the pressing piece 203, and the other part of the clamping groove is arranged on the surface of the base layer 220. Further, the surface of the card slot, and particularly the portion attached to the base layer 220, is provided with a trigger. The trigger is connected to the control module 300 by a wire. In particular, the trigger is embodied as a resistance wire. The control module 300 inputs current to the resistance wire through the wire, and the resistance wire heats up to enable the slot shape to lose the restraining force to the pressing piece 203, so that the pressing piece 203 is folded to a curled state, and the pressed buffering piece 204 is released to provide corresponding buffering force.

According to a preferred embodiment, the guard structure 200 of the present invention may include a plurality of individually adjustable guard structures 200 that are respectively attached to different guard sites of a user according to preset rules. Specifically, the guard portion of the user may be any one or all of a shoulder region, an elbow region, a wrist region, a waist region, and a knee region, and is not limited thereto. Further, the guard structure 200 of the present invention may include a first guard structure attached to the user's shoulder, a second guard structure attached to the user's elbow, a third guard structure attached to the user's wrist, a fourth guard structure attached to the user's knee, and/or a fifth guard structure attached to the user's waist.

According to a preferred embodiment, when the first guard structure is correspondingly attached to the shoulder region of the user, the plurality of cushioning portions 210 included in the first guard structure are arranged side by side in a shoulder armor shape in an arc/arch structure, wherein the arc extension direction of the cushioning portions 210 coincides with the shoulder arm circumference. Alternatively, the arc-shaped extension direction of the buffer 210 intersects with the arm extension direction. Specifically, for the first protective structure disposed on the shoulder of the user, the inflated and released state of the cushioning member 204 is not uniform, but is substantially in a state in which the thickness of both ends of the arc is greater than that of the middle portion thereof in the released state. In particular, for the shoulder, the side face of the shoulder is more easily damaged by falling collision relative to the surface far away from the trunk of the body, so that the buffer thickness of the two arc ends of the shoulder armor-shaped protection structure is larger than that of the middle area, the buffer degree of the shoulder when the shoulder is subjected to side collision can be preferentially ensured, and the collision damage is reduced.

According to a preferred embodiment, as shown in fig. 5, when the cushioning members 204 are pressed by the pressing members 203 to allow the cushioning members 204 to form a cushioning structure having both ends thicker than the middle in the released state, arc/arch-shaped protrusions may be formed on the surface of the base layer 220 where the cushioning portions 210 are correspondingly provided. Further, the buffer 204 is disposed on the arc-shaped/arched protruding surface of the base 220, and the pressing member 203 is fixed to the surface of the buffer 204 by the fixing member 201 and the locking member 202 at both ends of the buffer 204, so that the buffer 204 is preloaded on the surface of the base 220 to form a state in which the thickness of the middle is thinner than that of both ends. When the detection module 100 detects that the user falls, the plurality of buffering parts 210 in the first protection structure are started, wherein the locking piece 202 is excited and triggered by the control module 300, the pressing acting force of the pressing piece 203 on the buffering piece 204 is invalid, the buffering piece 204 is changed from a pre-tightening state to a releasing state, and the buffering piece 204 is in a state that the two ends of the buffering piece are thicker than the middle in the releasing state, so that impact damage to the front side and the rear side of the shoulder of the user when the shoulder of the user impacts the ground is relieved.

According to a preferred embodiment, the plurality of buffer parts 210 included in the second shielding structure are arranged in a sleeve shape in a bar-shaped structure or a circular structure when the second shielding structure is correspondingly attached to the elbow region of the user. Specifically, when the sleeve-shaped second guard structure is constructed in a bar-shaped structure, the length extension direction of the plurality of buffer portions 210 included in the second guard structure substantially coincides with the arm extension direction. On the other hand, when the sleeve-shaped second guard structure is constructed in a circular structure, the plurality of buffering portions 210 included in the second guard structure are disposed around the circumference of the arm. Further, for the second protective structure disposed at the elbow of the user, the expanded release state of the cushioning member 204 is not uniform, but is substantially in a state in which the thickness of both ends of the arc shape is smaller than that of the middle portion thereof in the released state. In particular, for the elbow of the user, the most vulnerable part is the elbow joint, and the buffer capacity of the elbow guard area of the protection structure can be improved through the mode.

According to a preferred embodiment, as shown in fig. 6, when the cushioning members 204 are pressed by the pressing members 203 to allow the cushioning members 204 to form a cushioning structure having both ends thinner than the middle in the released state, arc-shaped/arch-shaped depressions may be formed in the surface of the base layer 220 where the cushioning portions 210 are correspondingly provided. Further, the cushioning member 204 is disposed on the curved/arched concave surface of the base layer 220, and the pressing member 203 is fixed to the surface of the cushioning member 204 by the fixing member 201 and the locking member 202 at both ends of the cushioning member 204, thereby pre-tightening the cushioning member 204 on the surface of the base layer 220 to form a state in which the thickness is greater in the middle than at both ends. When the detection module 100 detects that the user falls, the plurality of buffering parts 210 in the second protection structure are started, wherein the locking piece 202 is excited and triggered by the control module 300, the pressing acting force of the pressing piece 203 on the buffering piece 204 is invalid, the buffering piece 204 is changed from a pre-tightening state to a releasing state, and the two ends of the buffering piece 204 are thinner than the middle state in the releasing state, so that impact damage to the elbow joint of the user when the elbow of the user impacts the ground is relieved.

According to a preferred embodiment, when the third guard structure is correspondingly attached to the wrist region of the user, the plurality of buffer parts 210 included in the third guard structure are arranged in a bar-shaped structure, and the length direction of the plurality of buffer parts 210 of the bar-shaped structure is consistent with the arm extension direction. Further, a portion of the cushioning portion 210 of the strip-shaped structure is located on the palm end face (e.g., the palm root portion), and another portion is located on the wrist end face. In particular, with the wrist of the user as a boundary, the length ratio of the buffer portion 210 in the strip-shaped structure at the palm end face and the wrist end face of the user is, for example, 1.5 to 2:0.5 to 1. Specifically, the buffer portion 210 passes from the wrist to the palm junction in the length direction and covers the half palm of the palm, thereby protecting the wrist in the event of an accident. Because the palm face of the palm is preferentially used to contact the falling face when the human body falls down, the palm can bear larger impact force, and the joint between the palm and the wrist is extremely likely to be injured (such as dislocation, fracture and the like) when the palm is scratched, so that the wrist guard area of the third protection structure can ensure that the palm cannot be scratched due to collision, and can limit excessive deformation of the wrist and the palm.

According to a preferred embodiment, when the fourth protective structure is correspondingly attached to the knee region of the user, the plurality of cushioning portions 210 included in the fourth protective structure are arranged in a sleeve shape in a bar-shaped structure or a circular structure, similar to the second protective structure at the elbow. Specifically, when the sleeve-shaped fourth guard structure is constructed in a bar-shaped structure, the length extending direction of the plurality of cushioning portions 210 included in the fourth guard structure substantially coincides with the leg extending direction. On the other hand, when the sleeve-shaped fourth guard structure is constructed in a circular structure, the plurality of cushioning portions 210 included in the fourth guard structure are circumferentially arranged around the knee. Further, for the fourth guard structure disposed at the knee of the user, the expanded release state of the cushioning member 204 is not uniform, but is substantially in a state in which the thickness of both ends of the arc shape thereof in the release state is smaller than that of the middle portion thereof. In particular, for the knee of the user, the most vulnerable part is the knee joint, and the cushioning capacity of the knee protection area of the protection structure can be improved through the mode.

According to a preferred embodiment, when the fifth protective structure is correspondingly attached to the waist region of the user, the plurality of cushioning portions 210 included in the fifth protective structure are arranged in a waistband shape in a longitudinal direction in a strip-shaped structure, and at least the plurality of cushioning portions of the strip-shaped structure are provided in a direction perpendicular to the waistband circumference in the waistband-shaped protective structure for protecting the buttocks and the crotch, and for the protective structure of the waist-protecting crotch region, the thickness of the waistband-shaped protective structure in the cushioning state can be expanded at least to be in the same vertical plane as the buttocks and the crotch. For human body, the spine of upper part of the body is connected with the hip bone of lower part of the body, and under the general circumstances, the width of hip bone in horizontal direction is greater than the width of backbone in horizontal direction far away to lead to when taking place to fall the collision, the power that hip bone position and backbone position bore appears great deviation, and the condition such as dislocation appears probably to the backbone position under inertial action, thereby lead to the injury that falls to increase, and the protection architecture in waist support crotch region keeps the horizontal distance of waist and buttock, crotch unanimous when falling, under the circumstances that buttock, crotch contact the collision plane and stop the motion in preference, the expanded protection architecture can cushion the power that is applyed to the backbone by inertia, greatly reduce the injury that the waist collision brought.

In particular, for the above-described guard structures attached to different parts of the user, the control module 300 can independently control the guard structures 200 of the individual guard parts to be opened according to the user drop information acquired by the detection module 100. Further, for the protection structure 200 of the same protection part (such as elbow), the control module 300 can control the opening of the buffer parts 210 in different directions according to the toppling direction of the user when the user falls, which is obtained by the detection module 100, so as to avoid opening the buffer parts 210 without providing buffering force while providing an effective buffering effect, and reduce the use times of the buffer parts 210. Frequent activation of the unnecessary portion buffer 210 easily causes the corresponding components to be used in advance, because the components generally have a limited number of times of recycling, and when the corresponding buffer force needs to be provided through the buffer 210, the buffer 210 may not be activated normally due to unexpected aging and jamming, and the limited buffer force capable of being provided is also reduced with the previous multiple openings, even loses the originally expected buffer effect, especially for the buffer 210 made of the memory sponge according to the present invention, the more the number of times of use, the worse the buffer effect, which helps to prolong the service life of the protection system by reducing the number of times the unnecessary buffer 210 is opened.

Further, for the above-mentioned protective structure attached to different parts of the user, the thickness of the buffer part 210 or the buffer piece 204 in the protective structure 200 of each protective area in the released state is not uniform, and is designed according to the human body structural characteristics of each protective area, and the thickness of the buffer piece 204 is reduced as much as possible on the premise of ensuring the effective buffering effect, so that the protective structure 200 is lighter, convenient for the user to wear daily, and does not affect the daily activities thereof.

According to a preferred embodiment, referring to fig. 1, the fall protection system provided by the invention may further comprise a prompting module 400. The prompting module 400 may be integrated with the detection module 100 that is wearable attached to the user's body. In particular, the prompting module 400 is configured to provide fall status determination and prompting to a user or a terminal in remote communication with the fall detection system, so that the fall of the user can be known in time. Specifically, one specific example of the prompt module 400 may be a signal indicator light. In particular, the signaling light may be driven by a preset program instruction, which generally comprises an editable indication scheme of a visual optical signal formed by adjustable color, time and other parameters, and by driving the signaling light to emit the visual optical signal, the auxiliary information of whether the user falls is provided.
