technical field

The present application relates to the field of rehabilitation medical equipment, in particular to a training device suitable for fine hand movements.

Background technique

Disuse and ause disorders seriously hinder the recovery of hand function, especially the recovery of fine motor function, making it difficult for patients in the late stage of neurorehabilitation to achieve independent activities of daily living. For the early rehabilitation of hand dysfunction, equipment is combined with artificial passive activities, including but not limited to pneumatic hand training, pneumatic hand training, low-frequency electrical stimulation and biofeedback training, etc. Hand function rehabilitation measures in the middle and later stages of the rehabilitation process rely on single manipulation training, simple Mechanical occupational therapy and other traditional facilities. Although advances in science and technology have increased the interactivity of traditional training equipment, the patient's compliance is not high. The reason is that, first, the interactivity is simply to complete the game goal mechanically, and does not fully mobilize the patient's subjective initiative. First, such equipment usually depends on the venue, which is not conducive to the participation of patients between departments; second, although rehabilitation manipulators, hand function robots, and mirror equipment are small in size and easy to carry, they are essentially a kind of advanced passive physical activity. Little contribution was made in increasing patient active participation.

Fig. 3 is a working principle diagram of a training device for fine hand movements provided by an embodiment of the present application. In combination with Figure 3, take the patient performing one of the finger strength training as an example, specifically: the patient performs middle finger strength training, and when the patient's middle finger is bent, it drives the steel frame (7) on the middle finger fingertip to move to the fingertip, thereby Drive the transfer steel wire (8) that is fixed with the steel frame (7) to move to the fingertip, and then drive the conduction steel wire (9) that is fixed with the other end of the transfer steel wire (8) to move to the fingertip. Because the other end of the conduction steel wire (9) is fixed on the far-end ring magnet (15), thereby driving the far-end ring magnet (15) to move to the near-end ring magnet (11) and compressing the spring (13) between the two to generate pressure. The pressure sensor (12) fixed on the proximal ring magnet (11) senses the pressure and transmits it to the signal processing module (16) connected to it, which converts the pressure signal into an electrical signal and generates an acousto-optic control signal according to the electrical signal and image signal, and send the acousto-optic control signal to the acousto-optic component (2), the acousto-optic component (2) generates visual and auditory feedback, and simultaneously sends the image signal to the communication device (4) through the Bluetooth module (17) The connected display terminal (5) displays the strength training situation of the middle finger in real time according to the image signal. The power module (18) provides power for the pressure sensor (12), the signal processing module (16), the bluetooth module (17) and the acousto-optic component (2).

It can be understood that the above embodiment adopts the training situation of one finger, wherein each driving steel wire corresponds to a group of magnets, a spring and a pressure sensor. Each of the five fingers corresponds to a transmission steel wire.

As shown in Figure 8, the training device also includes an interfinger ring assembly (37). The interfinger fixing ring assembly includes a steel fixing frame through which the interfinger fixing ring assembly is fixed on the finger, and the interfinger fixing ring assemblies on adjacent fingers are connected with each other through specific materials to form a fixed finger of the overall structure. The interfinger fixing ring structure is made of silicone plastic material, which conforms to ergonomics and can fit the gap between fingers. There is a steel fixing frame inside, and the outside is made of silicone material. The five interfinger fixing rings are connected by steel wires, converge downwards and are fixed on the Velcro part, and can be fixed with the Velcro at the root of the palm of the finger. It can be used with finger cots for individual finger training.

It can be understood that the steel wires are used to connect each other to form a whole, so that the interfinger fixing ring is easy to wear. It adopts ergonomic design, and the silicone plastic material can be closer to the patient's fingers, and it is not easy to fall off. The fingers cover the root of the palm, making the fixation more firm and not easy to slip, which can better assist patients in training.

Figure 4 is a schematic diagram of the structure of the finger cover. The finger cover (1) is divided into the palm surface and the back of the hand. The palm surface is made of skin-friendly soft fabric combined with the non-slip and wear-resistant structure between the fingers. The Velcro of the ring fits; the back of the hand is divided into upper, middle and lower layers. The lower skin-friendly layer is made of breathable and sweat-absorbing material, the middle layer is made of stair cloth to increase wear resistance, and the upper layer is made of spliced fiber leather to increase the toughness, wear resistance and durability of finger sleeves. dirty.

The acousto-optic assembly (2) also includes a pulley block locking button (23), which is used to lock the steel wire skeleton (7) passing through the pulley block, so that the steel wire skeleton (7) cannot slide, so that the finger cot (1) is in an unfolded position, and fits the fingers The inter-fixing ring assembly (37) can be used as finger-pointing exercise alone. After unlocking, the steel wire frame (7) can move freely, and normal finger strength training can be performed. When receiving the sound and light control signal from the signal processing module (16), visual and auditory feedback is performed.

The visual and auditory feedback of the acousto-optic assembly (2) will be described below with specific examples in conjunction with FIG. 10 .

When performing inter-finger resistance training, according to the evaluation results of the affected hand, patients with Brunnstrom stage 2-3 or muscle strength 2-3 choose low-intensity resistance kits, which can stimulate acousto-optic feedback and remotely record training intensity; 3-4 Patients with stage 5-6 or muscle strength level 5 should choose a high-intensity resistance set. When the finger pulls the steel wire and puts pressure on the five pressure sensors, all five light strips light up, the visual feedback is all activated, and the sound feedback at the same time: You are great, the rainbow is coming out. Through acousto-optic feedback, the patient's training passion and subjective initiative are stimulated, making the treatment effect more effective. When the finger pulls the steel wire to give pressure to more than three pressure sensors, feedback is also given, the visual feedback is activated accordingly, and the audio feedback is: you are great, come on. When the pressure is less than three pressure sensors, the visual feedback is activated accordingly, and the audio feedback is suspended.

The acousto-optic assembly provided in this embodiment, the movement of each finger can drive the corresponding pressure sensor, activate a separate light band to light up, so that the patient can get more intuitive feedback when training each finger, and judge the size of the training force .
