When the first sensing module 21 senses the movement of the wand 1, it generates a wand movement signal. When the second sensor module senses the user, it generates a sensor signal. Each touch sensing module 23 generates a touch sensing signal when it touches an object (not shown in the figure). The tilting sensing module 24 generates a tilting sensing signal when the stick body 1 is tilted.

In this embodiment, the first sensing module 21 is a gyroscope, which can detect the movement track of the stick body 1 to generate the stick body movement signal. The second sensing module 22 is an infrared sensor, which can sense when the user is within a predetermined distance and generate the sensing signal. The touch sensing module 23 is a pressure sensor, which can generate the touch sensing signal when it touches the object. The dumping sensor module 24 is a sensory The ball sensor corresponding to the tilting angle of the stick body 1 can generate the tilting sensing signal when it senses that the stick body 1 is tilted to more than a predetermined tilting angle.

However, in implementation, there are many ways to detect the movement trajectory of the stick body, sense the user within the predetermined distance, sense whether the feet are in contact with an object, and sense whether the stick body is tilted. At this time, the types of the first sensing module 21, the second sensing module 22, the touch sensing module 23, and the tilt sensing module 24 are not limited to the above-mentioned aspects.

The processing unit 3 is disposed on the main pole portion 11 of the pole body 1 and signally connects the first sensing module 21 and the second sensing module 22 of the sensing unit 2. The processing unit 3 is used to use the rod body movement signal generated by the first sensing module 21 to calculate the single movement distance of the rod body 1, and to determine that the single movement distance of the rod body 1 is greater than a predetermined The distance between the rods and when the induction signal is received, a rehabilitation achievement signal is generated. The processing unit 3 is also used to calculate the cumulative number of the rehabilitation achievement signal within a predetermined time. In this embodiment, the predetermined rod distance is 20 to 60 cm, but it is not limited to the above data during implementation, and can also be adjusted according to the user's rehabilitation situation. In other variations of this embodiment, the predetermined rod distance can also be derived from the average of the previous movement distances of the rod body 1 (for example, 2 to 5 times).

The control unit 4 is signally connected to the touch sensing modules 23 and the tipping sensing module 24 of the sensing unit 2, and also signals to the processing unit 3, the light emitting unit 6, the reminding unit 7, and the wireless communication unit 5.

When the control unit 4 receives one of the touch sensing signals, it controls the light-emitting unit 6 to emit light to indicate that the wand 1 has touched the ground and is used to illuminate the road conditions.

In other variations of this embodiment, the control unit 4 will also receive all the contact-sensing modules 23 within a predetermined time (for example, within 1 to 2 seconds) after receiving the first contact-sensing signal. When the sensor signal is touched, the light-emitting unit 6 is controlled to emit light outward, which indicates that the stick body 1 has touched the ground and is completely facing the ground.

On the other hand, the control unit 4 can be triggered by the rehabilitation achievement signal, and control the reminding unit 7 to generate a prompt message representing that the user has achieved the rehabilitation action; the control unit 4 can also receive the first contact When no more than a predetermined number of contact-sensing signals are received within a predetermined time from the sensing signal, for example, no more than 2 contact-sensing signals have been received, or all contact-sensing signals of the contact-sensing module 23 have not been received When the control unit 4 can be triggered by the tilting sensing signal, the reminding unit 7 is controlled to generate a warning message representing the tipping of the stick body 1 Prompt message.

In addition, the control unit 4 will send a notification message corresponding to the reminder message to the electronic device 8 via the wireless communication unit 5 when controlling the reminder unit 7 to generate a reminder message; and the control unit 4 will also send a notification message corresponding to the reminder message to the electronic device 8 via the wireless The communication unit 5 transmits the accumulated count data to the electronic device 8.

When the sensory multifunctional crutches of the present invention are used by the user located in a rehabilitation medical institution, for example, when the rod body 1 is moved to one of the leg parts 12 to touch the ground, the The light-emitting unit 6 emits light, for example, color light or flashing light. In other variations of this embodiment, the light-emitting unit 6 can also emit light when all the leg portions 12 are in contact with the ground.

When the user starts to perform rehabilitation with the crutch device, the control unit 4 will control when the single movement distance of the stick body 1 is greater than the predetermined stick distance, and when the user subsequently approaches the stick body 1, The reminder unit 7 sends out a corresponding reminder message, indicating that a rehabilitation action is achieved, and at the same time, via the wireless communication unit 5, the cumulative number of rehabilitation times accumulated by the processing unit 3 is sent to the electronic device 8, so that medical personnel or The family members understand the user's rehabilitation situation.

On the other hand, when the user is walking with the sensor-type multifunctional crutches, the control unit 4 determines the other of the feet 12 of the stick body 1 When several of them do not touch the ground continuously, or do not receive more than a predetermined number of contact sensing signals within a predetermined time (for example: not receiving more than 2 or all contact sensing signals), the reminder unit 7 will be controlled to send out Corresponding prompt messages to alert the user and remind people around to check whether the user is unstable in standing or swaying in steps. When the control unit 4 determines that the stick body 1 falls, it also controls the reminding unit 7 to send out a corresponding prompt message to immediately alert the surrounding personnel to see whether the user has fallen with the stick body 1 falling. In addition, when the control unit 4 controls the reminder unit 7 to send out the reminder message, it will also send a corresponding notification message to the electronic device 8 via the wireless communication unit 5 at the same time, so as to remind the medical staff who are not around the user Or family members, the user may be in an unsafe situation.

It should be noted that the number of the contact sensing modules 23 is not limited to four, and can also be three, five... etc. according to the actual number of the leg portions 12. If the reminding unit 7 only needs to generate a prompt message representing that the stick body 1 is in contact with the ground, and does not need to generate a prompt message representing that the stick body 1 is unstable, then the number of the contact sensing module 23 only needs one, and it is set in it One leg 12.

Referring to Figures 3 and 4, there is a second embodiment of the sensor-type multifunctional crutch of the present invention. This second embodiment is similar to the first embodiment, except that the second embodiment also includes an applicable The third sensing module 25 is worn on one of the feet of the user, and the processing unit 3 is used to calculate the number of movements of the user by using the human body movement signal, and to determine the number of movements of the wand 1 The moving distance is greater than the predetermined rod When the sensor signal is received and the number of movements is 1, the rehabilitation achievement signal is generated. In this embodiment, the third sensing module 25 is a gyroscope worn on the ankle of the user. However, during implementation, there are many ways to detect the movement trajectory of the wand body. Therefore, during implementation, the type of the third sensing module 25 is not limited to the above-mentioned aspect.

By using the third sensing module 25, it can also be ensured that the rehabilitation achievement signal can be generated when the user’s step distance is equivalent to the single movement distance of the crutches, so as to further filter the user’s steps. The short-distance small step walking way to reach the stick body 1 is a rehabilitative action that is not up to the standard.

In summary, the sensory multifunctional crutch of the present invention utilizes the design of the sensing unit 2 and the processing unit 3 of the sensory multifunctional crutch. When the user performs rehabilitation actions, the sensory crutch The multifunctional crutches can automatically determine whether the user has reached the standard rehabilitation action, so that the user can perform the rehabilitation on his own, improve the convenience of rehabilitation, and effectively enhance the user's willingness to recover; in addition, the feeling The test type multifunctional crutches can also calculate the cumulative number of rehabilitation actions and detect whether the user is in a stable state when using the sensor type multifunctional crutches. Therefore, it can indeed achieve the purpose of the invention.
