Description

An active functional electrical stimulation armband

technical field

The invention relates to an armband in the field of rehabilitation, in particular to an active functional electrical stimulation armband.

Background technique

According to the statistics of the World Health Organization, there are currently about 25-30 million stroke (stroke) patients in the world, and there are at least 6 million in my country, and this number is still on the rise. If you add paralyzed patients from other causes, the number will be even more staggering. 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 very heavy physical labor from the physiotherapist. 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 being stimulated, the muscles of the patients contract and drive the limbs to produce desired movements. At present, functional electrical stimulation can realize flexion, extension and grasping of upper limbs of paralyzed patients; standing, walking, cycling of lower limbs, correction of foot drop, etc.

With the increasing development of electronic technology, functional electrical stimulation technology is becoming more and more mature, and some commercial products have come out, such as Parastep.Freehand in the United States, Finetech in the United Kingdom, Bionic Glove in Canada, Handmaster in the Netherlands and so on. In recent years, new control technology and biosensor technology have endowed the functional electrical stimulation system armband with more comprehensive functions. For example, EEG and EMG signals have become important control sources for functional electrical stimulation.

The communication module includes a wireless transmission circuit, and mainly realizes the communication between the entire armband and the outside world through wireless Bluetooth technology.

When in use, first install the integrated sheet (5) on the elastic hook (1), the specific operation is as follows: as shown in Figure 3, pass the support rod (11) at the end of the integrated sheet (5) through the through hole (13) , take the upper pressure plate (9) so that the positioning cap (10) covers the upper end of the support rod (11), and then press the upper pressure plate (9) in the downward direction in Figure 3, so that the upper ends of the two support rods (11) They are separated from each other, that is, the upper ends of the two struts (11) are opened, and at the same time, the lower ends of the struts (11) are also separated from each other. The limit slot (15) moves in, and as the upper pressure plate (9) moves down, the upper pressure plate (9) presses the elastic tabs (6) and separates to both sides until the support rod (11) clamps the elastic member (14). ), the middle torsion spring on the middle shaft (12) is tightened, and at this time, under the action of the return spring of the elastic tab (6), the elastic tab (6) returns to the inner position and snaps into the slot (8), complete For temporary locking, the function of the elastic member (14) is mainly to prevent the rigid connection from damaging the member when the strut (11) is clamped.

After one end of the integrated sheet (5) is installed with the lateral surface (1-1), the other end is installed in the same way; because as shown in Figure 1, both ends of the integrated sheet (5) are connected with an elastic hook (1);

When it is necessary to disassemble the integrated sheet (5) at a certain position, there are two ways, one is to hold the integrated sheet (5) with one hand, and the other hand directly push the handle (7) to both sides with the fingers, so that the elastic snap The tongue (6) leaves the upper pressing 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 struts (11) are quickly retracted inward, and the upper pressing plate (9) is lifted upwards, Then release the handle (7). At this time, the position of the upper pressure plate (9) is higher than the elastic tab (6), so the upper pressure plate (9) can be removed directly. One end, remove the integrated sheet (5).

Another disassembly method, as shown in Figure 4, can be disassembled by using a manual unlocker, which is more convenient than pushing the handle (7) directly with fingers. Separate the lower ends and hold or jam the handle (7). If a gap is provided at the lower ends of the two struts (20), the handle (7) can be directly clamped. Then, as shown in Figure 4, press down on the hand plate ( 18), so that the hand pressure plate (18) gradually moves down against the upper movable shaft (23), so that the lower ends of the two struts (20) are gradually separated, and the elastic tabs (6) are pushed up, so that the upper pressure plate (9) Popped up to complete disassembly.

The entire installation and disassembly process is very convenient and quick.

When the present invention is in use, the arm loop structure formed by the integrated sheet (5) temporarily fixed on the elastic hook (1) is put on the arm, and there are two modes in the use process, one is the electromyography mode, and the other is the EMG analysis mode.
