Description

Technical Field

[0001] The invention relates to an armband in the field of rehabilitation, in particular to an active functional electrical stimulation armband. Background Art

[0002] For the early rehabilitation of paralyzed patients, exercise therapy is a very important and effective means. At present, the exercise rehabilitation of stroke patients is generally carried out with the assistance of physical therapists, sometimes relying on some simple traditional equipment. In this way, the patient's movement is passive, which requires the physical therapist to do very heavy physical labor. Functional electrical stimulation is a common technology in the field of rehabilitation. It uses artificial weak current pulse signals to stimulate the skeletal muscles of paralyzed patients. After the patient's muscles are stimulated, they contract and drive the limbs to produce the desired movement. At present, functional electrical stimulation can achieve flexion, extension and grasping of the upper limbs of paralyzed patients; standing, walking, riding a bicycle for the lower limbs, and correcting foot drop, etc.

[0003] With the development of electronic technology, functional electrical stimulation technology has become more mature, and some commercial products have been launched, such as Parastep. Freehand in the United States, Finetech in the United Kingdom, Bionic Glove in Canada, Handmaster in the Netherlands, etc. In recent years, new control technology and biosensor technology have given the functional electrical stimulation system armband more comprehensive functions.

When replacing, only the integrated sheet 5 on the corresponding elastic hook 1 needs to be replaced.

[0037] The integrated chip 5 is divided into an electromyographic analysis and functional electrical stimulation integrated module 2 and a communication module 4;

[0039] The integrated sheet 5 is temporarily connected to the elastic hook 1 through a temporary locking mechanism;

[0040] The temporary locking mechanism includes an "X"-shaped elastic bracket, an upper pressing plate 9 and an elastic latch tongue 6;

[0041] The "X"-shaped elastic bracket is an "X"-shaped structure formed by two cross-combined support rods 11. The two support rods 11 are movably connected at the cross position through a middle rotating shaft 12 (the two support rods 11 can rotate around the middle rotating shaft 12), so that the upper and lower ends of the two support rods 11 form a structure that can be opened and closed; (just like the principle of scissors)

[0042] A through hole 13 is provided on the transverse surface 1 - 1 of the elastic hook 1 that contacts the integrated sheet 5 ;

The elastic latch 6 is arranged on both sides of the through hole 13, and the elastic latch 6 is placed on the horizontal surface 1-1 through the rotating shaft 6-1 (the horizontal surface 1-1 at this time can be made of a hard material, such as a hard plastic material, and the side wall 1-2 connected to the horizontal surface 1-1 is made of an elastic material, such as elastic plastic, etc.; the side wall 1-2 and the horizontal surface 1-1 form a U-shaped structure, which can be connected by an integrated adhesive connection, or a plastic hard plate can be arranged at the horizontal surface 1-1 during sequential molding, and the plastic hard plate can be coated with elastic plastic to form an integrated structure during preparation; of course, they can also be all elastic structures, and then an additional hard plate can be directly bonded to the horizontal plate) and the elastic latch 6 can rotate around the rotating shaft 6-1, and a reset torsion spring is arranged on the rotating shaft 6-1 (the function of the reset torsion spring is that when the two elastic latches 6 are pressed to both sides to separate to both sides, the elastic latch 6 can be returned to the original position by the reset torsion spring. Figure 3 The upper pressing plate 9 is clamped in the upright state shown.

[0046] A middle torsion spring for controlling the ends of the support rod 11 to be close to each other (the ends are retracted) is arranged on the middle rotating shaft 12 .

[0047] An inner side wall of the through hole 13 is provided with an elastic member 14 .

[0048] The bottom of the upper pressing plate 9 is provided with a positioning cap 10 which covers the upper end of the support rod 11 when in use, and the upper end of the support rod 11 can move in the positioning cap 10 when in use.

[0049] The upper end face A of the elastic latch 6 is an inclined smooth arc surface, the two ends B of the bottom surface of the upper pressure plate 9 are inclined smooth arc surfaces with the same inclination direction as the upper end face A, and the two ends of the top surface of the upper pressure plate 9 are provided with slots 8 for the elastic latch 6 to extend into.

[0050] A handle 7 is provided on the top of the elastic latch 6 for easy carrying;

[0051] It also includes a manual unlocker that can separate the elastic tongue 6 to both sides when in use;

[0052] The manual unlocking device comprises a hand pressure plate 18, a bottom box 19 and a herringbone structure formed by two support rods 20;

[0053] The bottom box 19 is arranged at the bottom of the hand pressing plate 18, and the upper ends of the two support rods 20 are movably connected through an upper movable shaft 23 (the two support rods 20 can rotate around the movable shaft 23);

[0054] The upper movable shaft 23 is located in the bottom box 19. The side wall of the bottom box 19 is provided with two vertical strip shaft limiting holes 21 and two vertical strip support rod extension holes 2. The two ends of the upper movable shaft 23 are respectively extended into the two vertical strip shaft limiting holes 21 and can move up and down along the limiting holes; the two support rods 20 are respectively extended from the two vertical strip support rod extension holes 22 and can open and close relative to each other.

[0055] The present application may also include a posture analysis module, which includes a posture analysis circuit and uses MEMS to monitor the human body's motion posture. The communication module includes a wireless transmission circuit, which mainly realizes the communication between the entire armband and the outside world through wireless Bluetooth technology.

[0056] When in use, first install the integrated sheet 5 on the elastic hook 1, and the specific operation is as follows: Figure 3 As shown, the support rod 11 at the end of the integrated sheet 5 passes through the through hole 13, the upper pressing plate 9 is taken to get the positioning cap 10 to cover the upper end of the support rod 11, and then Figure 3 The upper pressing plate 9 is pressed in the downward direction of the middle, so that the upper ends of the two supporting rods 11 are separated from each other, that is, the upper ends of the two supporting rods 11 are opened. At the same time, the lower ends of the supporting rods 11 are also separated from each other, and the transverse sliding rod 16 moves in the side wall limiting groove 15. As the upper pressing plate 9 moves downward, the upper pressing plate 9 presses the elastic latch tongue 6 to separate to both sides until the supporting rod 11 clamps the elastic member 14, and the middle torsion spring on the middle rotating shaft 12 is tightened. At this time, under the action of the return spring of the elastic latch tongue 6, the elastic latch tongue 6 returns inwardly and is clamped in the clamping groove 8 to complete the temporary locking. The function of the elastic member 14 is mainly to prevent the rigid connection from damaging the component when the supporting rod 11 is clamped. Of course, the elastic member 14 can also be not provided. The rigid connection can also achieve temporary fixation of the integrated sheet 5; in order to increase the effect, the position where the elastic member 14 contacts the supporting rod 11 can be set to an inclined surface;

[0057] The function of the positioning cap 10 is to prevent the upper pressing plate 9 from falling off from the support rod 11, which can be achieved without being set; the card slot 8 is to prevent the elastic card tongue 6 from falling off from the upper pressing plate 9, which can be achieved without being set.

[0058] After one end of the integrated sheet 5 and the horizontal surface 1-1 are installed, the other end is installed in the same way; Figure 1 As shown, an elastic hook 1 is connected to each end of the integrated sheet 5;

[0059] When it is necessary to remove the integrated sheet 5 at a certain position, there are two ways. One is to hold the integrated sheet 5 with one hand, and use the other hand to directly push the handle 7 to both sides with the fingers, so that the elastic tongue 6 leaves the upper pressure plate 9, and the middle torsion spring on the middle rotating shaft 12 is released and reset, so that the upper ends of the two support rods 11 are quickly retracted inward, pushing up the upper pressure plate 9, and then releasing the handle 7. At this time, the position of the upper pressure plate 9 is higher than the elastic tongue 6, so the upper pressure plate 9 can be directly removed. After one end is disassembled, the other end is disassembled in the same way to remove the integrated sheet 5.

[0060] Another way to disassemble, such as Figure 4 As shown, a manual unlocker can be used for disassembly, which is more convenient than directly pushing the handle 7 with fingers. When disassembly is performed using a manual unlocker, the lower ends of the two support rods 20 are separated and supported or clamped on the handle 7. If notches are provided at the lower ends of the two support rods 20, the handle 7 can be directly clamped, and then Figure 4 As shown, the hand pressure plate 18 is pressed downward, so that the hand pressure plate 18 gradually pushes against the upper movable shaft 23 and moves downward, so that the lower ends of the two support rods 20 gradually separate and push open the elastic latch 6, so that the upper pressure plate 9 is bounced up, and the disassembly is completed.

[0061] The entire installation and removal process is very convenient and quick.

[0062] When the present invention is used, the armband structure formed by the integrated sheet 5 temporarily fixed on the elastic hook 1 is put on the arm. There are two modes in use, one is the electromyography analysis mode, and the other is the functional electrical stimulation mode. These two modes can be automatically switched as needed. In practical applications, the armband can have three functions: (1) active functional electrical stimulation therapy based on electromyography signals of both arms; (2) assisted electrical stimulation therapy; (3) learning therapy based on external guidance (including video recording, VR).

[0063] The armband includes an integrated module of electromyography analysis and functional electrical stimulation and a communication module (which may also include a posture analysis module); wherein the integrated module of electromyography analysis and functional electrical stimulation includes a surface electromyography signal acquisition circuit, an electromyography signal processing circuit and a pulse electrical stimulation circuit; and at the same time, this module can automatically switch between electromyography analysis mode and functional electrical stimulation mode according to demand. The posture analysis module includes a posture analysis circuit, which uses MEMS to monitor the human body's motion posture. The communication module includes a wireless transmission circuit, which mainly realizes the communication between the entire armband and the outside world through wireless Bluetooth technology. In the electromyography analysis mode, the armband should be worn on a healthy arm to measure and extract effective surface electromyography information; while the armband in the functional electrical stimulation mode should be worn on the arm that needs treatment, and pulse stimulation is issued by analyzing and processing the extracted surface electromyography signals, thereby achieving a therapeutic effect. The electromyography analysis mode collects the surface electromyography signals of the healthy arm through the surface electromyography signal acquisition circuit, and then analyzes and processes them in the electromyography signal processing circuit. In the functional electrical stimulation mode, the surface electromyography signal acquisition circuit is used to collect the surface electromyography signal of the arm to be treated, and then analyze, compare and process it in combination with the data of the healthy arm in the electromyography signal processing circuit, and then send instructions to the pulse electrical stimulation circuit based on the comparison results. Finally, the pulse electrical stimulation circuit sends electrical stimulation of corresponding magnitude to the arm to achieve the stimulation effect.

[0064] The active functional electrical stimulation therapy function based on the electromyographic signal of both arms is suitable for patients with one arm injury; the patient wears two armbands at the same time, the armband worn by the healthy arm is set to the electromyographic analysis mode, and the arm that needs treatment wears the armband set to the functional electrical stimulation mode, and the data measured by the healthy arm is used to control the armband in the functional electrical stimulation mode, so as to achieve the purpose of electrical stimulation. The auxiliary electrical stimulation therapy function is suitable for patients with impaired arm function; this function uses surface electromyography to provide biofeedback signals to conduct active and passive movement training with the subjective participation of the patient. It can synchronize electromyographic detection and electrical stimulation output; when the patient's active action causes muscle contraction, the present invention will adjust the strength and stimulation time of the electrical stimulation in real time according to the size and duration of the electromyographic signal. The larger the patient's subjective movement amplitude, the greater the electromyographic signal strength, and the greater the electrical stimulation strength, so that the patient can complete the subjective required action with the help of electrical stimulation. During the stimulation, if the patient does not want to move, the muscle contraction stops, the electromyographic signal also stops, and the electrical stimulation stops immediately.

[0065] The learning and treatment function based on external guidance (including video recording and VR) means that the patient can learn and train related movements by wearing the present invention according to relevant video recording and VR teaching.

[0066] In summary, the entire armband is made of flexible material. Its structure is to connect multiple integrated pieces together through elastic hooks and design them into the style of an armband. Therefore, it can simultaneously collect surface electromyographic signals of multiple channels at different positions of the arm, thereby realizing a variety of movements.

[0067] The working process of the specific embodiment is as follows:

[0068] The workflow of the present invention is: select the mode of the armband according to the needs, and then you can start training. In the electromyography analysis mode, the surface electromyography signal of the healthy arm is collected by the surface electromyography signal acquisition circuit, and then analyzed and processed in the electromyography signal processing circuit. In the functional electrical stimulation mode, the surface electromyography signal acquisition circuit is used to collect the surface electromyography signal of the arm to be treated, and then analyzed, compared and processed in the electromyography signal processing circuit, and then sent instructions to the pulse electrical stimulation circuit according to the comparison results, and finally the pulse electrical stimulation circuit sends electrical stimulation of corresponding magnitude to the arm to achieve the treatment effect.

[0069] Function (1) Active functional electrical stimulation training based on electromyographic signals of both arms. This function is suitable for patients with one injured arm. Patients should wear two armbands at the same time. The armband worn on the healthy arm is set to electromyographic analysis mode, and the arm that needs treatment is set to functional electrical stimulation mode. The data measured by the healthy arm is used to control the armband in functional electrical stimulation mode, so as to achieve the purpose of electrical stimulation. Its main working process is to collect the surface electromyographic signals of the healthy arm through the surface electromyographic acquisition circuit, and then use the electromyographic signal processing circuit to process and analyze them as the control source. The muscles of both arms correspond one by one, and the control source is sent to the armband in functional electrical stimulation mode through wireless. The armband in functional electrical stimulation mode will compare and analyze the received control source data with the data of the injured arm detected by its own surface electromyographic acquisition circuit through its own electromyographic signal processing circuit; then send the command to the pulse electrical stimulation circuit.

[0070] Function (2) Assisted electrical stimulation training. This function is suitable for patients with impaired arm function. This function uses surface electromyography to provide biofeedback signals to conduct active and passive movement training with the subjective participation of patients. It can synchronize electromyography detection and electrical stimulation output. When the patient's active movement causes muscle contraction, the present invention will adjust the strength and stimulation time of the electrical stimulation output by the pulse electrical stimulation circuit in real time through the electromyography signal processing circuit according to the size and duration of the electromyography signal collected by the surface electromyography acquisition circuit. The greater the patient's subjective movement amplitude, the greater the electromyography signal intensity, and the greater the electrical stimulation intensity. The patient can complete the subjective desired movement with the help of electrical stimulation. During the stimulation, if the patient does not want to move, the muscle contraction stops, the electromyography signal also stops, and the electrical stimulation stops immediately.

[0071] Function (3) Learning therapy based on external guidance (including video, VR). This function means that patients can learn and train related movements by wearing the present invention according to relevant videos and VR teaching. The above process has changed the traditional sports rehabilitation method. Physical therapists do not need to personally assist paralyzed patients in training through physical contact. Patients can use the system armband to perform rehabilitation training by themselves, which greatly reduces the workload of physical therapists.

[0072] In summary, the present invention has the advantages of being easier and more convenient to wear, miniaturized product, capable of being reused multiple times, having a long service life, simple operation, flexible replacement and installation, and greater adaptability.
