Description

Technical Field

[0001] The present invention relates to the technical field of walking aids, and more particularly, to an intelligent ward walking aid. Background Art

[0002] A walking aid, also known as a lower limb orthosis, is a walking support tool for the elderly with limited mobility, certain trauma patients, hemiplegic patients, and the disabled to assist walking or exercise their physical strength. With the help of it, people can walk slowly with ease. Most of the existing ward walking aids are like Figure 2 and Figure 3 As shown, it can often provide a force-bearing support point (walking support tool) for patients or can be used for patients to hold and push. Some ward walking aids also have a seat board installed on them for convenient sitting and resting.

[0003] After extensive retrieval, the applicant found some typical prior arts. For example, a Chinese invention patent with the application number 202011460605.0 discloses an intelligent walking aid, which can be remotely controlled by remote sensing or mobile phone, uses ultrasonic sensors as auxiliary obstacle avoidance, has a structure that can be quickly disassembled and assembled, can lock the motor, and has an adjustable-direction lighting lamp installed in the front of the walking aid, which can automatically trigger the alarm function when the user encounters an emergency. Another example is a Chinese invention patent with the application number 201710873981.4, which discloses a gravity brake walking aid. When an elderly person suddenly loses balance and falls during walking or exercise, the walking aid can sense the gravity drop and activate the brake function, ensuring the safety of the elderly during walking or activities, and at the same time improving the stability and versatility of the walking aid. Still another example is a Chinese invention patent with the application number 201811394085.0, which discloses a postoperative rehabilitation walking aid, which has the advantages of being easy to use, being able to walk automatically without the patient exerting force, and having stable walking.

[0004] In summary, although the existing ward walking aids in the prior art have their respective advantages, they only have one function and cannot switch to different states (such as the supporting state and the pushing state) according to the supporting force points of patients, and their functions are relatively single and need to be improved. Summary of the Invention

[0005] Based on this, in order to solve the problem that the existing ward walking aids in the prior art only have one function, cannot switch to different states according to the supporting force points of patients, and have relatively single functions, the present invention provides an intelligent ward walking aid, and its specific technical solution is as follows:

[0006] An intelligent ward walking aid includes two force-receiving parts and a driving part.

[0007] The two force-receiving parts are respectively installed at different positions on the frame body.

[0008] The driving part is installed at the bottom of the frame body and is configured to be able to switch the working state according to the force conditions of the two force-receiving parts; among them, the working states include the supporting state and the pushing state.

[0009] By providing two force-receiving parts and switching the working state according to the force conditions of the two force-receiving parts, the ward walking aid can be rotatably connected to the frame body so that the rotating wheels of the driving part can roll relative to the bottom surface or be fixedly connected to the frame body to provide a supporting force point, enriching the functions of the walking aid, improving the degree of intelligence, meeting the needs of different types of patients, and having good practicability.

[0010] Furthermore, force sensors are installed on both force-receiving parts, and the driving part compares the magnitudes of the forces on the two force-receiving parts to switch the working state.

[0011] Furthermore, the driving part includes a braking component.

[0012] The braking component is installed on the frame body and is configured to be able to lock the rotating wheels according to the magnitudes of the forces on the two force-receiving parts and adjust the friction force between the brake pads and the rotating wheels on the basis of keeping the rotating wheels rotatable relative to the frame body.

[0013] Furthermore, the two force-receiving parts are respectively a supporting force-receiving part and a pushing force-receiving part. The supporting force-receiving part includes two force points at different positions, and the pushing force-receiving part includes at least one force point. Each force point is matched with a force sensor, and the force sensors corresponding to different force points are all provided with identification numbers.

[0014] Furthermore, the braking component includes brake pads, brake wires, and a traction component. The traction component receives the signal instructions of the controller and controls the friction force between the brake pads and the rotating wheels by tightening and relaxing the brake wires to lock the rotating wheels or make the rotating wheels rotatable relative to the frame body.

[0015] Furthermore, the controller analyzes and identifies the magnitude of the force on each force point through the pressure signals fed back by the force sensors. When the pressure value of one of the force points of the supporting force-receiving part is greater than the first preset pressure threshold, the controller determines that the working state is the supporting state. When the pressure values of all the force points of the supporting force-receiving part are less than the first preset pressure threshold and the pressure value of one of the force points of the pushing force-receiving part is greater than the first preset pressure value, the controller determines that the working state is the pushing state.

[0016] Furthermore, when the pressure values of all the force points of the two force-receiving parts are less than the first preset pressure threshold, the controller determines that the walking aid is in the waiting state.

[0017] Furthermore, the traction component is a driving motor or an electric telescopic rod.

[0018] Further, one end of the brake cable is fixed to the output shaft of the drive motor. The controller drives the brake cable to act by rotating the drive motor, thereby controlling the frictional force between the brake pad and the rotating wheel.

[0019] Further, one end of the brake cable is fixed to the telescopic end of the electric telescopic rod. The controller drives the brake cable to act by driving the telescopic movement of the electric telescopic rod, thereby controlling the frictional force between the brake pad and the rotating wheel.

[0029] In the present invention, the so-called "first" and "second" do not represent specific quantities and orders, but are only used for name distinction.

[0030] Embodiment 1:

[0031] Most of the existing ward walking aids are like Figure 2 and Figure 3 as shown. Most of the time, they can provide a force-bearing support point (walking support tool) for patients or can be supported and pushed by patients. Some ward walking aids also have a seat board installed on them to facilitate sitting and resting. Most of these ward walking aids only have one function and cannot be switched to different states according to the force application points of patients, and their functions are relatively single and need to be improved.

[0032] In order to improve the existing ward walking aids, enrich their functions, and enable them to switch to different usage states or usage functions according to the different force application points of patients, as Figure 1 shown, the present invention provides an intelligent ward walking aid, which includes two force-bearing parts 1 and a driving part 2.

[0033] The two force-bearing parts are respectively installed at different positions on the frame body and are configured to be supported by users and provide force application points.

[0034] The driving part is installed at the bottom of the frame body 3 and is configured to switch the working state according to the force-bearing conditions of the two force-bearing parts.

[0035] Among them, the working states include a supporting state and a pushing state.

[0036] When the working state is the supporting state, the driving part is fixedly connected to the frame body to provide a support force-bearing point; when the working state is the pushing state, the driving part is rotatably connected to the frame body so that the rotating wheel of the driving part can roll relative to the bottom surface.

[0037] In the present invention, the walking aid for the ward is provided with two force-bearing parts and switches the working state according to the force-bearing conditions of the two force-bearing parts, so that the walking aid can be rotatably connected to the frame body so that the rotating wheel of the driving part can roll relative to the bottom surface or fixedly connected to the frame body to provide a support force-bearing point, enriching the functions of the walking aid, improving the degree of intelligence, enabling it to meet the needs of different types of patients, and having good practicability.

[0038] In this embodiment, force sensors are installed on both force-bearing parts, and the driving part compares the magnitudes of the forces on the two force-bearing parts to switch the working state.

[0039] The ward walking aid further includes a controller, which is electrically connected to the force sensors, receives the signals fed back by the force sensors, and analyzes the magnitudes of the forces on the two force-bearing parts according to the signals. The controller switches the working state of the walking aid according to the magnitudes of the forces on the two force-bearing parts.

[0040] Preferably, the two force-bearing parts are a supporting force-bearing part 10 and a pushing force-bearing part 11. The supporting force-bearing part includes two force-bearing points at different positions, and the pushing force-bearing part includes at least one force-bearing point. Each force-bearing point is matched with a force sensor, and the force sensors corresponding to different force-bearing points are provided with corresponding identification numbers. That is to say, the identification numbers of the force sensors corresponding to different force-bearing points are all different.

[0041] The purpose of setting the identification numbers is to better judge the specific magnitudes of the forces on different force-bearing points.

[0042] The controller analyzes and identifies the magnitude of the force on each force-bearing point through the pressure signals fed back by the force sensors. When the pressure value of one of the force-bearing points of the supporting force-bearing part is greater than the first preset pressure threshold, the controller determines that the working state is the supporting state. When the pressure values of all the force-bearing points of the supporting force-bearing part are less than the first preset pressure threshold and the pressure value of one of the force-bearing points of the pushing force-bearing part is greater than the first preset pressure value, the controller determines that the working state is the pushing state.

[0043] When the pressure values of all the force-bearing points of the two force-bearing parts are less than the first preset pressure threshold, the controller determines that the walking aid is in the waiting state.

[0044] The controller switches the working state of the walking aid according to the magnitudes of the forces on the two force-bearing parts, which can improve the intelligence level of the intelligent walking aid, better serve the patients, and meet the needs of the patients.

[0045] For some patients (such as patients with muscular dystrophy), during the rehabilitation treatment process, they often need to carry out walking rehabilitation treatment. At different stages of the rehabilitation treatment, the patients need to carry out different degrees of muscle strength training. That is to say, this kind of rehabilitation treatment is a progressive process, and the magnitude of the muscle force of the patients will change with different rehabilitation treatment stages.

[0046] Existing ward walking aids often cannot control the resistance magnitude of the walking aid in the pushing state according to different rehabilitation treatment stages of the patients. To solve this technical problem, in this embodiment, the driving part includes a braking component.

[0047] The braking component is installed on the frame body and is configured to lock the rotating wheel according to the magnitudes of the forces applied to the two force-receiving parts and to adjust the frictional force between the brake pad and the rotating wheel while keeping the rotating wheel rotatable relative to the frame body.

[0048] Specifically, the braking component includes a brake pad, a brake wire, and a traction component. The traction component receives a signal instruction from the controller and controls the frictional force between the brake pad and the rotating wheel by tightening or loosening the brake wire, so as to lock the rotating wheel or make the rotating wheel rotatable relative to the frame body. Since the brake pad is controlled to act through the brake wire, and thus the frictional force between the brake pad and the rotating wheel is controlled, the installation structures among the brake pad, the brake wire, and the rotating wheel all belong to conventional technical means in the art, and thus will not be elaborated herein.

[0049] Through the braking component, the intelligent ward walking aid can lock the rotating wheel according to the magnitudes of the forces applied to the two force-receiving parts and adjust the frictional force between the brake pad and the rotating wheel while keeping the rotating wheel rotatable relative to the frame body, that is, it can control the tightness of the rotation of the rotating wheel according to the patient's rehabilitation treatment stage. That is to say, the intelligent ward walking aid can adjust the magnitude of the force required to be pushed according to actual needs, which is helpful for the patient's rehabilitation treatment.

[0050] Preferably, the traction component is a driving motor or an electric telescopic rod. One end of the brake wire is fixed to the output shaft of the driving motor or the telescopic end of the electric telescopic rod. The controller drives the brake wire to act through the rotation of the driving motor or the telescopic movement of the electric telescopic rod, and thus controls the frictional force between the brake pad and the rotating wheel. When the frictional force between the brake pad and the rotating wheel is greater than a preset resistance value, the rotating wheel can be locked by the friction pad.

[0051] Embodiment 2:

[0052] Most of the existing ward walking aids are like Figure 2 and Figure 3 shown. Most of the time, they can provide a force-bearing support point (a walking support tool) for the patient or can be supported and pushed by the patient. Some ward walking aids also have a seat board installed thereon to facilitate sitting and resting. Most of these ward walking aids only have one function and cannot switch to different states according to the patient's support force application points, and their functions are relatively single and need to be improved.

[0053] In order to improve the existing ward walking aids, enrich their functions, and enable them to switch to different usage states or usage functions according to different patient support force application points, as Figure 1 shown, the present invention provides an intelligent ward walking aid, which includes two force-receiving parts and a driving part.

[0054] Two force-bearing parts are respectively installed at different positions on the main body of the frame, and are configured to be supported by the user and provide a force application point.

[0055] The driving part is installed at the bottom of the main body of the frame and is configured to switch the working state according to the force conditions of the two force-bearing parts.

[0056] Among them, the working states include a supporting state and a pushing state.

[0057] When the working state is the supporting state, the driving part is fixedly connected to the main body of the frame to provide a supporting force point; when the working state is the pushing state, the driving part is rotatably connected to the main body of the frame so that the rotating wheel of the driving part can roll relative to the bottom surface.

[0058] In the present invention, the ward walking aid enriches the functions of the walking aid and improves the degree of intelligence by providing two force-bearing parts and switching the working state according to the force conditions of the two force-bearing parts, so that the walking aid can be rotatably connected to the main body of the frame so that the rotating wheel of the driving part can roll relative to the bottom surface or fixedly connected to the main body of the frame to provide a supporting force point, meeting the needs of different types of patients and having good practicability.

[0059] In this embodiment, force sensors are installed on both force-bearing parts, and the driving part compares the force magnitudes of the two force-bearing parts to switch the working state.

[0060] The ward walking aid further includes a controller, which is electrically connected to the force sensors, receives the signals fed back by the force sensors and analyzes the force magnitudes of the two force-bearing parts according to the signals. The controller switches the working state of the walking aid according to the force magnitudes of the two force-bearing parts.

[0061] Preferably, the two force-bearing parts are respectively a supporting force-bearing part and a pushing force-bearing part. The supporting force-bearing part includes two force application points at different positions, and the pushing force-bearing part includes at least one force application point. Each force application point is matched with a force sensor, and the force sensors corresponding to different force application points are all provided with identification numbers.

[0062] The controller analyzes and identifies the force magnitude of each force application point through the pressure signals fed back by the force sensors. When the pressure value of one of the force application points of the supporting force-bearing part is greater than the first preset pressure threshold, the controller determines that the working state is the supporting state. When the pressure values of all the force application points of the supporting force-bearing part are less than the first preset pressure threshold and the pressure value of one of the force application points of the pushing force-bearing part is greater than the first preset pressure value, the controller determines that the working state is the pushing state.

[0063] When the pressure values of all the force application points of the two force-bearing parts are less than the first preset pressure threshold, the controller determines that the walking aid is in a waiting state. When the walking aid is in the waiting state, the controller also enables the user to obtain the actual distance between the patient and himself.

[0064] Each patient sends real-time positioning information and personal identity information at a preset frequency through a bound mobile intelligent terminal or an intelligent wearable device. The controller obtains the real-time positioning information and calculates the actual distance between the patient and itself based on the real-time positioning information.

[0065] When the actual distance is less than the preset distance value, the controller switches its working state according to the patient's hospitalization information. Here, the controller is also communicatively connected to the hospital server. When the controller calculates that the actual distance between the patient and itself is less than the preset distance value, it feeds back the patient's personal identity information to the server. The server searches for and obtains the patient's hospitalization information based on the patient's personal identity information and feeds it back to the controller.

[0066] The controller determines the patient's physical state based on keywords in the patient's hospitalization information, such as the patient's age, registration department, and drug list. Preferably, the specific method for determining the patient's physical state based on keywords in the patient's hospitalization information can be to pre-store a mapping table in the controller. In this mapping table, different keywords correspond to different physical states, and different physical states correspond to a support state or a promotion state.

[0067] In this way, by communicating with the hospital server, the intelligent ward walking aid can switch to the required working state in advance when the patient enters the preset range of the walking aid, so as to better provide convenience for the patient and improve the degree of intelligence at the same time.

[0068] Each patient can also pre-enter the usage requirements of the walking aid through a bound mobile intelligent terminal or an intelligent wearable device. The mobile intelligent terminal or the intelligent wearable device sends real-time positioning information, personal identity information, and usage requirements to the controller at a preset frequency, facilitating the controller to switch the working state.

[0069] Preferably, when more than one patient is detected within the preset distance value range, the controller can temporarily switch the working state of the walking aid to the support state or the promotion state, and then switch to the specific working state according to the force conditions of the two force-receiving parts. When no patient is detected within the preset distance value range, the controller temporarily switches the working state of the walking aid to the support state to prevent the walking aid from moving due to vibration or wind.

[0070] The controller switches the working state of the walking aid according to the force magnitudes of the two force-receiving parts, which can improve the degree of intelligence of the intelligent walking aid, better serve the patients, and meet the needs of the patients.

[0071] For some patients (such as those with muscle weakness), during the rehabilitation process, they often need to undergo walking rehabilitation therapy. At different stages of rehabilitation therapy, patients need to perform muscle strength training of different intensities. That is to say, this rehabilitation therapy is a progressive process, and the amount of muscle force exerted by the patient will change with different rehabilitation therapy stages.

[0072] Existing ward walking aids often cannot control the resistance of the walking aid in the pushing state according to different rehabilitation therapy stages of patients. To solve this technical problem, in this embodiment, the driving part includes a braking component.

[0073] The braking component is installed on the frame body and is configured to lock the rotating wheel according to the force magnitudes of two force-receiving parts and adjust the friction force between the brake pad and the rotating wheel on the basis of keeping the rotating wheel rotatable relative to the frame body.

[0074] Specifically, the braking component includes a brake pad, a brake wire, and a traction component. The traction component receives a signal command from the controller and controls the friction force between the brake pad and the rotating wheel by tightening or relaxing the brake wire to lock the rotating wheel or make the rotating wheel rotatable relative to the frame body.

[0075] The intelligent ward walking aid can, through the braking component, lock the rotating wheel according to the force magnitudes of two force-receiving parts and adjust the friction force between the brake pad and the rotating wheel on the basis of keeping the rotating wheel rotatable relative to the frame body, that is, can control the tightness of the rotation of the rotating wheel according to the patient's rehabilitation therapy stage. That is to say, the intelligent ward walking aid can adjust the magnitude of the force required to be pushed according to actual needs, which is helpful for the patient's rehabilitation therapy.

[0076] Preferably, the traction component is a driving motor or an electric telescopic rod. One end of the brake wire is fixed to the output shaft of the driving motor or the telescopic end of the electric telescopic rod. The controller drives the brake wire to act by rotating the driving motor or telescoping the electric telescopic rod, and then controls the friction force between the brake pad and the rotating wheel. When the friction force between the brake pad and the rotating wheel is greater than a certain value, the rotating wheel can be locked by the friction plate.

[0077] In this embodiment, the intelligent ward walking aid further includes an input module for inputting pushing assistance. The input module is installed on the frame body and includes, but is not limited to, a touch display screen or physical buttons. The controller is electrically connected to the input module, obtains the pushing resistance input by the patient, and then controls and adjusts the friction force between the brake pad and the rotating wheel. Here, the magnitude of the friction force is proportional to the number of rotation turns of the driving motor or the telescopic amount of the electric telescopic rod. That is, the controller controls the magnitude of the friction force by controlling the number of rotation turns of the driving motor or the telescopic amount of the electric telescopic rod and makes the friction force match the input pushing resistance.

[0078] It should be noted that the pushing resistance of the input is not necessarily equal to the actual frictional force. The pushing resistance only needs to be proportional to the frictional force. That is to say, the greater the input pushing resistance value, the greater the actual frictional force.

[0079] The controller can also preset a maximum pushing resistance value. When the input pushing resistance is greater than the maximum pushing resistance value, the input pushing resistance is calibrated as the maximum pushing resistance value, and the number of rotation turns of the driving motor or the telescopic amount of the electric telescopic rod is controlled according to the maximum pushing resistance value.

[0080] As a preferred technical solution, the controller is further configured to obtain the rehabilitation treatment stage information of the patient through the server, and set the pushing resistance according to the rehabilitation treatment stage information.

[0081] Specifically, for different rehabilitation treatment stage information, different corresponding pushing resistances are set. On the walking aid, an identity recognition module such as a camera is set to identify the identity information of the patient using the walking aid by taking a face image of the user of the walking aid. Of course, the identity information of the patient corresponding to the actual distance being zero can also be calculated according to the actual distance between the mobile intelligent terminal or the smart wearable device bound to the patient and the walking aid.

[0082] After identifying the identity information of the user of the walking aid, the controller feeds back the identity information to the server, obtains the rehabilitation treatment stage information of the patient through the server, and sets the pushing resistance according to the rehabilitation treatment stage information.

[0083] It should be noted that the pushing resistance set according to the rehabilitation treatment stage information is a temporarily set pushing resistance. When the patient inputs a new pushing resistance through the input module, the old pushing resistance (i.e., the temporarily set pushing resistance) will be updated and overwritten.

[0084] At the same time, the controller is further configured to obtain the magnitude of the pushing resistance value set by the patient, the corresponding rehabilitation treatment stage, and the pushing time value of the walking aid at the pushing resistance value. When the pushing time value of the walking aid at the pushing resistance value is greater than the preset time value, the controller feeds back the magnitude of the pushing resistance value set by the patient, the corresponding rehabilitation treatment stage, and the pushing time value of the walking aid at the pushing resistance value to the server.

[0085] The server stores the magnitude of the pushing resistance value set by the patient, the corresponding rehabilitation treatment stage, and the pushing time value of the walking aid at the pushing resistance value.

[0086] The server stores the magnitudes of the pushing resistance values set by multiple patients, the corresponding rehabilitation treatment stages, and the pushing time values of the walking aid at the pushing resistance values. The mode (only one mode exists) of the pushing resistance values corresponding to the same disease and the same rehabilitation treatment stage is set as the preset pushing resistance value for the same disease and the same rehabilitation treatment stage. The controller sets the pushing resistance of the walking aid according to the preset pushing resistance value.

[0087] If there is no mode for the pushing resistance values corresponding to the same disease and the same rehabilitation treatment stage, calculate the average value of the pushing resistance values corresponding to the same disease and the same rehabilitation treatment stage, and use this average value as the preset pushing resistance value; if there are two or more modes for the pushing resistance values corresponding to the same disease and the same rehabilitation treatment stage, calculate and randomly select one mode as the preset pushing resistance value or calculate the average value of multiple modes as the preset pushing resistance value.

[0088] By obtaining the patient's rehabilitation treatment stage information to set the pushing resistance of the walking aid, it can better provide rehabilitation treatment services for patients, enabling the walking aid to set corresponding pushing resistance according to the different rehabilitation treatment stages of different patients. While improving the degree of intelligence, it also helps the patient's rehabilitation treatment.

[0089] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0090] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
