[0003] In prior art, patient cannot well carry out flexion and extension and around movement according to standard action when carrying out ankle pump movement, and medical staff cannot guide for a long time, thus making the effect of patient's ankle pump movement not ideal. UTILITY MODEL CONTENT

[0004] The utility model aims at at least one of the technical problems in the related art to some extent: provide a kind of ankle pump movement rehabilitation pad, it can detect whether action is in place when patient carries out ankle pump movement, to give instruction information, so that patient self carries out ankle pump movement, action is standard, and effect is good.

[0005] Therefore, one purpose of the utility model is to provide a kind of ankle pump movement rehabilitation pad, it includes soft pad, the front surface of soft pad is equipped with air bag for supporting the heel of patient, soft pad is equipped with processor and at least one sensor that is connected with the processor, the processor is arranged at the position corresponding to the bottom of air bag, the sensor is set to detect the action of patient's foot on air bag, and can transmit detection information to processor;The processor includes processing unit that can receive the detection signal sent by sensor and compare with preset value and execution unit for receiving the control instruction sent by processing unit and giving corresponding instruction information based on the control instruction.

[0006] The above technical solution has the following advantages or beneficial effects: First, the patient's heel is supported by the soft pad, so that the patient's heel can drive the airbag to deform and move when doing flexion, extension and circumferential movements, thereby reducing the resistance between the heel and the bed, and the patient can perform ankle pump movements more labor-saving and standardized. Secondly, the sensor detects the movement of the patient's foot, and transmits the detection information to the processor in real time. The processor can compare the detection information with the preset value to determine whether the patient's ankle pump movement is standardized, thereby issuing corresponding control instructions, and finally converting the control instructions into indication information through the execution unit, so that the patient can standardize his or her own ankle pump movement after knowing the indication information.

[0007] Preferably, the sensor includes a signaler and a receiver, the receiver is electrically connected to the processor, the signaler is linked to the patient's foot, and the sensor can transmit the detected position information to the processor by detecting the relative position between the signaler and the processor.

[0008] Preferably, the airbag is detachably connected to the cushion. The detachable airbag can be replaced with a different airbag according to the weight of different patients, and the airbag is small in size, so the cushions can be easily stacked when the airbag and cushion are stored separately.

[0009] Furthermore, the processor is located within the airbag and fixed to the bottom of the airbag. Integrating the processor within the airbag not only facilitates simultaneous removal of the processor when the airbag and cushion are disassembled, facilitating separate stacking of the cushions, but also protects the processor from being crushed by external forces and causing damage.

At this time, an air layer is formed between the patient's heel and the soft pad, so that the patient's heel can move flexibly during the process of moving back and forth. At this time, the first sensor located at the top position of the airbag can better detect the movement position of the patient's heel, thereby judging the degree of plantar flexion and dorsiflexion of the foot during the ankle pump exercise and the maintenance time.

[0011] Preferably, the airbag is provided with a pressure sensor for detecting the pressure within the airbag, and the pressure sensor is communicatively connected to the processor. When the patient's heel is placed on the airbag, the pressure generated by the compression of the airbag can be detected by the pressure sensor, thereby automatically initiating the processor to receive the detection information from the pressure sensor and activate it. Conversely, when the heel is removed, the pressure sensor generates a detection signal after the pressure value is restored, causing the processor to automatically deactivate.

[0012] According to one example of the present invention, the sensor includes at least one second sensor, the second sensor's signaling device being configured to allow it to be removably mounted on a patient's foot near the toes. The second sensor's signaling device, when fixed to the patient's foot, can respond to plantar flexion and dorsiflexion of the patient's foot, thereby generating a detection signal.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The ankle pump exercise rehabilitation pad according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0026] The present invention provides an ankle pump exercise rehabilitation pad, as shown in the figure, which includes a soft pad 1, an air bag 5 for supporting the patient's heel is provided on the front of the soft pad 1, a processor 2 and at least one sensor communicatively connected to the processor 2 are provided on the soft pad 1, the processor 2 is arranged at a position corresponding to the bottom of the air bag 5, and the sensor is configured to detect the movement of the patient's foot on the air bag and can transmit the detection information to the processor 2;

[0027] The processor 2 includes a processing unit 7 capable of receiving a detection signal sent by a sensor and comparing the detection signal with a preset value, and an execution unit 8 for receiving a control instruction sent by the processing unit 7 and providing corresponding instruction information based on the control instruction.

[0028] Based on the preference of the above embodiment, the sensor includes a signaler and a receiver, the receiver is electrically connected to the processor, the signaler is linked to the patient's foot, and the sensor can transmit the detected position information to the processor 2 by detecting the relative position between the signaler and the processor 2.

[0029] Preferably, the processor 2 further includes a storage unit 6, in which a standard preset value for when the patient's foot performs ankle pump exercise is stored. Specifically, the preset value is a standard horizontal relative distance between the signal indicator and the receiver, which is divided into a standard plantar flexion distance and a standard dorsiflexion distance. If the patient's foot drives the signal indicator of the sensor to move synchronously during plantar flexion and dorsiflexion in the ankle pump exercise, the receiver can obtain position information of the signal indicator relative to the processor in real time and send the position information to the processor. The processor receives the position information, calls the preset value in the storage unit, and compares and analyzes the position information with the preset value, thereby giving a control instruction on whether the standard is met according to the result of the comparison and analysis. The execution unit 8 gives corresponding indication information based on the control instruction.

[0030] Specifically, the instruction information is voice information, the execution unit 8 of the processor includes at least a voice subunit, and the storage unit 6 stores audio information. The voice subunit calls the corresponding audio information in the storage unit 6 according to the control instruction and makes a human voice, such as "Please start plantar flexion", "Please start dorsiflexion", "Please start circling to the left", "Please start circling to the right", "Plantar flexion is in place", "Plantar flexion is not in place", "dorsiflexion is in place", "dorsiflexion is not in place", "Please maintain it in place", "1 second", "2 seconds", "3 seconds", "4 seconds", "5 seconds", "Relax".

[0031] Preferably, the processor 2 further includes a counting subunit and a timing subunit. The counting subunit is used to calculate the cumulative number of exercises, and the timing subunit is used to record the time of each exercise and the total exercise time. The number and time can correspond to relevant audio information and be broadcasted by the voice subunit.

[0032] Based on the preferred embodiment above, the airbag 5 is detachably connected to the cushion 1. A connecting base is provided at the bottom of the airbag 5, and the connecting base is snap-connected to a corresponding slot on the cushion 1.

[0033] Preferably, the processor 2 is located inside the airbag 5 and is fixed to the bottom of the airbag 5. The processor 2 is integrated into the airbag 5 while the airbag 5 is being produced, specifically, is embedded in the connection base of the airbag. The processor 2 has a power module inside, which is electrically connected to an external power supply device through wireless charging technology to charge the processor 2. Alternatively, an electric wire is embedded inside the soft pad 1, and the soft pad 1 is provided with a power cord connected to an external power supply or a battery box for installing a battery. The power cord or battery on the soft pad 1 is electrically connected to the processor 2 in the airbag 5 through the electric wire. The connection base of the airbag 5 is provided with a plug interface electrically connected to the processor 2, and the soft pad has a corresponding plug interface.

[0034] Based on one of the preferred examples of the sensor in the above embodiment:

[0035] like Figure 4 As shown, one of the at least one sensor is the first sensor 3, and the signaler in the first sensor 3 is arranged in the airbag 5 and fixed to the inner wall at the top position of the airbag 5, so that the signaler of the first sensor 3 can move synchronously with the movement of the patient's heel.

[0036] Specifically, the first sensor 3 is a Hall effect position sensor, whose receiver comprises multiple Hall effect elements, and whose signal transmitter comprises a movable magnet. The movable magnet is positioned within the airbag 5 and fixed to the inner wall at the top of the airbag 5, enabling the movable magnet to move synchronously with the movement of the patient's heel. The multiple Hall effect elements within the receiver are arranged along predetermined positions and fixed in position. These multiple Hall effect elements can be embedded within the cushion 1 and arranged radially, or positioned at the bottom of the airbag 5, with each Hall effect element corresponding to the front, back, left, and right positions. When the patient's heel drives the top of the airbag 5 and the movable magnet inside the top of the airbag 5 to move synchronously, each Hall effect element captures the moving path of the movable magnet. This position signal is transmitted to the processor 2, which compares and analyzes the position signal with a preset value within the processor 2. Based on the comparison and analysis results, the processor 2 generates a control instruction, causing the execution unit 8 to generate corresponding indication information according to the corresponding control instruction. If the patient's foot is in the correct position during the ankle pump exercise, a correct indication information is generated; if not, an incorrect indication information is generated.

[0037] Based on the second preferred example of the sensor in the above embodiment:

[0038] The sensor includes at least one second sensor 4, and the signaler of the second sensor 4 is configured to allow the signaler to be detachably mounted on the patient's foot near the toe.

[0039] Specifically, the second sensor 4 is a Hall effect position sensor, the receiver of which is a plurality of Hall effect elements, and the signal transmitter is a movable magnet. The movable magnet is fixed to the patient's foot near the toes by gluing or binding, so that the movable magnet can move synchronously with the plantar flexion or dorsiflexion of the patient's foot. The plurality of Hall effect elements in the receiver are embedded in the cushion 1 and arranged radially along the radial direction. The specific positions of the plurality of Hall effect elements on the cushion 1 can be arranged according to the specific movement path of the ankle pump movement. When the patient's foot drives the movable magnet to move, the Hall effect elements capture the movement path of the movable magnet. The position signal of the movable magnet is transmitted to the processor 2 in real time. The processor 2 compares and analyzes the position signal with a preset value preset within the processor 2 and issues a control instruction based on the comparison and analysis result, so that the execution unit 8 issues corresponding instruction information according to the corresponding control instruction. If the patient's foot is in the correct position during the ankle pump movement, the correct instruction information is issued; if it is not in the correct position, the incorrect instruction information is issued.

[0040] Preferably, the signaler of the second sensor 4 is provided with an adhesive layer or a strap. The adhesive layer can be attached to the instep or sole of the foot, and the strap can be tied to the toes. Specifically, the strap is a ring-shaped elastic band.

[0041] Based on the preference of the second sensor 4, the signaler of the second sensor 4 is a chip varistor, and its receiver is integrated in the processor. The chip varistor is attached to the sole and / or instep of the patient's foot, and the force generated by the bending of the chip varistor when the patient performs plantar flexion and dorsiflexion exercises is used to give a pressure detection signal. The detection signal is transmitted to the processor, and the processor 2 compares and analyzes the pressure detection signal with the preset value preset in the processor 2, and gives a control instruction based on the comparison and analysis result, so that the execution unit 8 gives corresponding indication information according to the corresponding control instruction. If the patient's foot performs ankle pump exercise in place, correct indication information is given, and if it is not in place, inappropriate indication information is given.

[0042] It should be understood that the above-mentioned sensors can adopt a variety of existing commercially available sensors, as long as they can detect the plantar flexion and dorsiflexion movements of the patient's foot and convert them into detection signals for transmission to the processor. Preferably, the Hall position sensors and chip varistors are conventional products in the sensor field, so the models and working principles of the above-mentioned sensors will not be described one by one.

[0043] Preferably, a first sensor 3 and a second sensor 4 are provided on the cushion 1 .

[0044] Based on the preferred embodiment described above, a pressure sensor (not shown) is provided within the airbag 5 for detecting the pressure within the airbag 5. This pressure sensor is communicatively connected to the processor 2. When the patient's heel is placed on the airbag 5, the weight of the foot compresses the airbag 5, thereby increasing the air pressure within the airbag 5. The pressure sensor can automatically turn the processor 2 on or off by detecting changes in the air pressure within the airbag 5. Specifically, when the pressure sensor detects that the air pressure within the airbag 5 exceeds a set pressure value, it sends a power-on command to the processor 2, which then turns on and issues a voice prompt. When the patient's heel is lifted and clears the airbag 5, the air pressure within the airbag 5 returns to its initial value. When the pressure sensor detects that the air pressure falls below the set pressure value, it sends a power-off command to the processor 2, which then shuts down after a delay and issues a voice prompt. This delay is intended to prevent the processor 2 from shutting down due to the patient's occasional, brief lifting of their foot.

[0045] Preferably, the soft pad 1 is provided with a receiving groove 1.1 for accommodating the signal of the second sensor 4. The soft pad 1 has a certain degree of elasticity, so when the signal of the second sensor 4 is a hard movable magnetic block, it can overcome the elastic reset force of the inner wall of the receiving groove 1.1 and fit tightly in the receiving groove 1.1, thereby preventing the loss of small particles of the movable magnetic block. When the signal of the second sensor 4 is a chip varistor, the soft pad 1 can be embedded with a corresponding hard area, which is concave to form a strip-shaped receiving groove 1.1. The chip varistor can be adsorbed in the receiving groove 1.1, thereby preventing the chip varistor from being damaged due to bending of the soft pad 1 when it is stored.

[0046] In the above embodiment, an ankle pump exercise rehabilitation pad of this embodiment is placed under each foot of the patient, so each patient needs to carry two ankle pump exercise rehabilitation pads. To facilitate portability, this embodiment is preferably configured such that: the cushion 1 is provided with two air cells 5, spaced apart along the width of the cushion 1. A processor 2 is provided on the cushion 1 at a position corresponding to each air cell 5, along with at least one sensor communicatively connected to each processor 2. Some modules of the two processors 2 can be merged, such as the speech sub-unit. The above modifications are simple mergers based on the present embodiment to reduce duplication of identical functions between the two processors.
