Therefore, the features limited by "first", "second" can be explicitly or implicitly included one or more. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0042] In the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] The present application provides a kind of suitable for intelligent stretching band and its use method, such as Figure 1 And Figure 2The present application discloses a smart stretching band, which is used for solving the problem of single patient leg rehabilitation training in the prior art, and enables the patient to control the training time and intensity, and avoids insufficient or excessive training. Specifically, the smart stretching band comprises an elastic band 100, a foot placement part 200, a holding part 300, a tension detection piece 400, a tension prompter and a timer 500. The overall length of the elastic band 100 is 100-120 cm, preferably 110 cm, and the width is 5-6 cm, preferably 6 cm. The overall thickness of the elastic band 100 is 2 mm, including a 1.5 mm elastic layer and a 0.5 mm anti-slip layer, so as to ensure flexibility and wear resistance. The leg rehabilitation training is performed by placing the foot in the middle of the elastic band 100 and then pulling the two ends of the elastic band 100 with both hands. In order to enable the foot to be better placed on the stretching band and avoid the foot from deviating during stretching of the elastic band 100 and affecting the rehabilitation training, the smart stretching band further comprises the foot placement part 200, which is arranged in the middle of the elastic band 100. When the foot is placed in the foot placement part 200, the foot placement part 200 can keep the foot fixed and avoid deviation of the foot. In order to better pull the elastic band 100, the holding part 300 is arranged at the two ends of the elastic band 100. After the patient places the foot in the foot placement part 200, the holding part 300 is pulled to stretch the elastic band 100 and enable the patient to perform rehabilitation training. When the patient performs leg rehabilitation training by pulling the elastic band 100, in order to enable the patient to perform training at a suitable tension intensity for a suitable time, the tension detection piece 400, the timer 500 and the tension prompter are arranged to prompt the patient whether the current tension intensity and duration are qualified. The tension detection piece 400 is arranged on the elastic band 100 and detects the tension in the elastic band. The timer 500 is arranged on the elastic band 100 and is electrically connected with the tension detection piece 400, so as to start timing when the tension detection piece 400 detects the tension. The tension prompter is electrically connected with the tension detection piece 400 and prompts the patient when the tension detection piece 400 detects the tension, so as to avoid insufficient training intensity of the patient and affect recovery, and avoid excessive training intensity of the patient and cause additional harm to the patient.

[0044] Specifically, the tension detection member 400 can be a tension sensor or a strain gauge or the like capable of detecting changes in tension. Specifically, as the leg stretching training is performed, different training intensities are required according to different leg recovery stages, and a certain amount of tension needs to be used for stretching for a period of time to complete one training. At this time, only when the tension detection member 400 detects a certain amount of tension, the starting signal is fed back to the timer 500, and the timer 500 starts timing, and when the tension detection member 400 detects that the tension at this time does not meet the preset resistance size of the current stretching training intensity, the tension detection member 400 feeds back the stop signal to the timer 500 at this time, and the timer 500 stops timing. Therefore, only when the tension is maintained at a certain tension size, the timer 500 will time, and when the tension does not meet this specific tension size, that is, the tension intensity at this time is greater than or less than the specific tension, the timer 500 will stop timing.

[0045] In order to more intuitively distinguish the stretching training states corresponding to different tension intensities and different stretching times, in the present application, the tension prompter further comprises an indicator light group 600, the indicator light group 600 is arranged on the elastic band 100, the indicator light group 600 comprises a plurality of indicator lights, the indicator light group 600 is electrically connected with the tension detection member 400 and the timer 500 respectively, so that different indicator lights in the indicator light group 600 light up when the tension detection member 400 detects different degrees of tension, and the indicator lights can also feed back different states whether the timer 500 is timing or not. Specifically, in the present application, the indicator light group 600 comprises a first indicator light 610, a second indicator light 620 and a third indicator light 630. In the present application, the first indicator light 610 is green, the second indicator light 620 is yellow, and the third indicator light 630 is red. In other embodiments, the first indicator light 610, the second indicator light 620 and the third indicator light 630 can also be other colors respectively. The three indicator lights correspond to the primary, intermediate and advanced levels of stretching training, that is, the first indicator light 610 corresponds to the primary, the second indicator light 620 corresponds to the intermediate, and the third indicator light 630 corresponds to the advanced. The primary is to perform gentle stretching, which is suitable for preoperative swelling pain and postoperative fragile period, the intermediate is to perform intensive training to activate muscle activity, and the advanced is high-intensity training to improve muscle endurance, so as to restore the function of the legs to normal level. The primary needs to stretch for 10 seconds when the tension is 30-40N, at which time the first indicator light 610 lights up, the intermediate needs to stretch for 15 seconds when the tension is 40-60N, at which time the second indicator light 620 lights up, and the advanced needs to stretch for 20 seconds when the tension is 60-70N, at which time the third indicator light 630 lights up.

[0046] In addition to the need to use a certain tension to stretch for a period of time, it is also necessary to perform multiple qualified stretching training to strengthen the rehabilitation training effect, so in the present application, the elastic band 100 is also provided with a counter 700, which is electrically connected with the tension detection piece 400 and the timer 500 respectively. Only when the tension detection piece 400 detects that the tension is at the specified tension value and the timer 500 completes a timing, the counter 700 will count again, which indicates that the patient completes a stretching training. After completing a qualified training, the counter 700 counts once, so that the patient can view the number of completed training in real time, which is more conducive for the patient to complete the specified leg rehabilitation training according to the requirements.

[0047] Therefore, when primary training is needed, pulling the holding part 300 makes the elastic band 100 be stretched until the first indicator light 610 is on, at which time the patient keeps the tension in the specified range, so that the first indicator light 610 accumulates for 10 seconds, and then the prompting assembly 800 gives a prompt to indicate that the patient completes a primary training, at which time the counter 700 completes a count. When the patient cannot keep the tension in the specified range, the timer 500 pauses the timing, feeds back a signal to the first indicator light 610, and the first indicator light 610 continues to flash, prompting the patient that the tension value is not consistent, which needs to be adjusted to meet the requirements of the current tension value, so that the timer 500 continues to time, and then the first indicator light 610 remains on. If the flashing of the first indicator light 610 lasts for a period of time, for example, 3 seconds, the first indicator light 610 is turned off, and at the same time the prompting assembly 800 gives another prompt that the training is invalid due to the inconsistent tension, which needs to be restarted.

[0048] When intermediate training is needed, pulling the holding part 300 makes the elastic band 100 be stretched until the second indicator light 620 is on, at which time the patient keeps the tension in the specified range, so that the second indicator light 620 accumulates for 15 seconds, and then the prompting assembly 800 gives a prompt to indicate that the patient completes an intermediate training, at which time the counter 700 completes a count. When the patient cannot keep the tension in the specified range, the timer 500 pauses the timing, feeds back a signal to the second indicator light 620, and the second indicator light 620 continues to flash, prompting the patient that the tension value is not consistent, which needs to be adjusted to meet the requirements of the current tension value, so that the timer 500 continues to time, and then the second indicator light 620 remains on. If the flashing of the second indicator light 620 lasts for a period of time, for example, 3 seconds, the second indicator light 620 is turned off, and at the same time the prompting assembly 800 gives another prompt that the training is invalid due to the inconsistent tension, which needs to be restarted.

[0049] When advanced training is required, the patient pulls the grip 300 to stretch the elastic band 100 until the third indicator light 630 illuminates. The patient then maintains the tension within the specified range, and the timer pauses. The third indicator light 630 illuminates for a cumulative 20 seconds, and then the prompt assembly 800 issues a prompt, instructing the patient to complete one advanced training session. The counter 700 then completes one count. If the patient fails to maintain the tension within the specified range, the timer 500 pauses and sends a signal to the third indicator light 630, causing it to flash continuously, notifying the patient that the tension value is not within the specified range and that the tension value needs to be adjusted to meet the current tension level. This causes the timer 500 to continue timing, and the third indicator light 630 remains lit. If the flashing of the third indicator light 630 continues for a period of time, for example, 3 seconds, the third indicator light 630 turns off, and the prompt assembly 800 issues another prompt, notifying the patient that the current training session is invalid due to the tension not being within the specified range and that the training session needs to be restarted.

[0050] In order to indicate whether the current stretching training meets the requirements, the smart stretching belt also includes a prompt component 800, which is electrically connected to the tension detection component 400, the timer 500 and the counter 700 respectively. Specifically, the prompt component 800 includes a vibration motor 810 and a buzzer 820. Therefore, when the counter 700 completes a count, it means that a training session is completed. The counter 700 sends a feedback signal to the buzzer 820, and the buzzer 820 beeps to prompt the patient to complete a training session. At this time, the patient can choose to proceed to the next training session or stop training. When the timer 500 stops timing, the timer 500 sends a feedback signal to the vibration motor 810. When the vibration motor 810 vibrates, it means that the training session is invalid, prompting the patient to adjust the tension and maintain the tension for a period of time, so that one of the indicator lights in the indicator light group 600 remains on for a period of time, so that the next training session meets the requirements.

[0051] Furthermore, before performing leg rehabilitation training, it is necessary to lift the legs so that the legs maintain a certain angle with a plane such as a bed surface, and then perform stretching training by stretching the elastic band 100 to ensure that the training is effective. Usually, the legs need to maintain an angle of more than 30° with the wound surface. Therefore, in order to enable the patient to keep the legs lifted during leg rehabilitation training, the smart stretching band also includes an inertial sensor 900. The inertial sensor 900 is electrically connected to the timer 500. The inertial sensor 900 is used to detect the lifting angle of the legs. Only when the lifting angle of the legs meets the requirements, the inertial sensor 900 sends a signal to the timer 500, thereby starting the timer 500 to run and count, and start stretching training.

[0052] In addition, the intelligent stretching belt further comprises a storage member for storing information such as the training time, the pulling strength and the stretching times each time, and the information can be transmitted to a mobile phone or other devices, so that the patient can check the historical data of the leg rehabilitation training and understand the training condition in time. The data in the storage member can be cleared, so that the intelligent stretching belt can be used by multiple people.

[0053] The foot placement part 200 comprises a placement groove 210, a foot anti-skid layer and a fixing assembly 220. The placement groove 210 is arranged at the middle part of the elastic belt 100 for placing the patient's foot, the width of the placement groove 210 is 8-10 cm, preferably 10 cm, so as to adapt to the span of the arch, and the depth is 1-1.5 cm, preferably 1.5 cm, so as to fit the curvature of the instep, disperse the pressure and avoid sliding. In order to further prevent the foot from sliding in the placement groove 210 and ensure the smooth progress of the stretching training, the foot anti-skid layer is arranged in the placement groove 210. The foot anti-skid layer is composed of a medical silica gel layer, which can improve the friction coefficient while resisting bacteria and prevent the foot from sliding. In the present application, the thickness of the foot anti-skid layer is 0.5-1 mm, preferably 0.5 mm. In addition, when the foot is placed in the placement groove 210, the foot needs to be fixed to avoid falling out of the placement groove 210 during the stretching process. Therefore, the foot placement part 200 further comprises the fixing assembly 220, which is installed on the elastic belt 100 to fix the patient's foot on the placement groove 210, so as to facilitate the subsequent stretching training process.

[0054] Specifically, the fixing assembly 220 comprises a mounting buckle 221 and a fixing band 222. The mounting buckle 221 is installed on the elastic belt 100 and arranged at one side of the placement groove 210. The fixing band 222 is divided into a fixed end and a movable end. The fixed end is fixed on the elastic belt 100, and the fixed end and the mounting buckle 221 are respectively located at two sides of the placement groove 210. The movable end is inserted into the mounting buckle 221. The fixing band 222 is made of elastic material. When the foot needs to be fixed in the placement groove 210, the foot is first placed in the placement groove 210, and then the movable end is inserted into the mounting buckle 221 to fix the fixing band 222, so that the fixing band 222 is wrapped around the instep.

[0055] Further, in order to adapt the intelligent stretching band in the application to different sizes of the foot, it is necessary to adjust the fixing band 222 to fix the foot between the fixing band 222 and the placement groove 210, so as to avoid that the fixing band 222 is too tight to cause additional harm to the patient, and also avoid that the fixing band 222 is too loose to cause the foot to slip out of the placement groove 210. The fixing assembly 220 further comprises a sticking piece 223 arranged on the movable end of the fixing band 222, so that after the movable end is inserted into the mounting buckle 221, the sticking piece 223 is attached to the fixed end. Therefore, after the movable end is inserted into the mounting buckle 221, the movable end is pulled to move towards the fixed end, and then the fixing band 222 is gradually pressed towards the placement groove 210, so that the fixing band 222 gradually binds the foot in the placement groove 210, and when the foot is fixed in the placement groove 210, the sticking piece 223 is attached to the fixed end of the fixing band 222, so as to keep the fixing band 222 from moving.

[0056] In addition, in order to further avoid the foot of the patient from falling off the foot placement part 200, and also to facilitate the patient to quickly place the foot in the correct position, the foot placement part 200 is further provided with a positioning groove 230. Here, by reducing the thickness of the elastic band 100, a concave position is formed, which is the positioning groove 230. Correspondingly, the anti-slip layer is arranged in the positioning groove 230 at this time, so that the patient can quickly place the foot in this position through the positioning groove 230, and then fix the foot in this position through the fixing assembly 220, which is convenient for subsequent rehabilitation training.

[0057] The holding part 300 comprises a palm pull ring 310 and a connecting port 320 arranged on the palm pull ring 310. The end of the elastic band 100 is mounted on the connecting port 320. Therefore, when the elastic band 100 needs to be pulled for stretching training, the foot is first placed in the placement groove 210 and fixed by the fixing assembly 220, the leg is lifted, and then the palm pull ring 310 is pulled to drive the elastic band 100 to stretch to start the training. Further, the palm pull ring 310 is further provided with an anti-slip layer to prevent the palm pull ring 310 from falling off the palm when the palm pull ring 310 is pulled, which causes the stretching band to retract and the palm pull ring 310 to hit the patient in the retraction process, thereby causing additional harm to the patient.

[0058] In the application, a use method of the intelligent stretching band is also included, which uses the intelligent stretching band in the application. The use method comprises the following steps:

[0059] The patient places the foot into the placement groove 210 and fixes the foot in the placement groove 210 by the fixing assembly 220;

[0060] The patient holds one palm pull ring 310 with each hand, and pulls the palm pull ring 310 to stretch the elastic band 100;

[0061] The tension detection member 400 detects the tension of the elastic band 100 in real time, so that the timer 500 starts timing when the tension reaches a certain value, and the counter 700 counts when the timer 500 accumulates a certain time;

[0062] When the tension detection member 400 detects different tension values, the different indicator lights of the indicator light group 600 are turned on respectively;

[0063] The prompting component 800 issues a prompt after the counter 700 completes a count, prompting the patient to complete a stretching training, and issues another prompt when the tension value changes or the tension duration does not meet the requirements, prompting the patient to adjust the training method to guide the patient to perform rehabilitation training.

[0064] Specifically, in the present application, the patient first places the foot sole into the placement groove 210, then inserts the movable end of the fixing band 222 into the installation buckle 221, and pulls the movable end of the fixing band 222 to move towards the fixed band 222, so that the fixing band 222 gradually tightens the foot sole and fixes the foot sole, and then the adhesive member 223 is attached to the fixed end. After the foot sole is fixed, it is determined whether the primary, intermediate or advanced training is required. After determination, the palm pull ring 310 is pulled to drive the elastic band 100 to stretch, and when the tension in the elastic band 100 reaches the tension requirement of different training levels, the corresponding indicator light in the indicator light group 600 is turned on. At this time, according to the requirements of different training levels, the tension is kept unchanged for a period of time, and at this time the indicator light is kept on to continuously stretch the leg. When a stretching is completed, the counter 700 completes a count, and the counter 700 sends a feedback signal to the buzzer 820, and the buzzer 820 emits a beep, thereby prompting the patient to complete a training. When the patient completes multiple trainings according to the requirements, the counter 700 records each training for the patient to check, and completes the specified number of trainings according to the training requirements of different levels.

[0065] It should be understood that the application of the present application is not limited to the above examples, and those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the present application.
