Description

Technical Field

[0001] The utility model relates to the technical field of myoelectric signal acquisition, in particular to a wearable myoelectric signal acquisition device. Background Art

[0002] The acquisition of myoelectric signals usually requires the use of activity collectors (also called myoelectric sensors or surface electrodes) to capture and record the electrical signals generated by muscle movement. These activity collectors can be placed on the surface of the skin to measure the bioelectric signals generated when the muscles contract and relax.

[0003] The thoracic outlet is an area at the top of the chest cavity, which is formed by the clavicle, the first rib and the suprasternal process. The thoracic outlet is the main channel connecting the upper limbs to the head, and contains important blood vessels, nerves and other structures. The acquisition of electromyographic signals at the thoracic outlet through an activity acquirer can provide a lot of useful information, such as evaluating muscle function, diagnosing and treating thoracic outlet syndrome, sports biomechanics research, and rehabilitation evaluation and training.

[0004] When collecting electromyographic signals at the thoracic outlet, it is generally necessary to use tape to stick the activity acquirer to the human body, but the fixing effect is not good and the activity acquirer is easy to fall off the body. Especially when the person being tested needs to move while being tested, the repeated expansion and contraction of the muscles will make the activity acquirer more likely to fall off, which can easily have a serious impact on the testing process. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that an activity acquirer is easy to loosen and fall off when collecting electromyographic signals at the thoracic outlet, and proposes a wearable electromyographic signal acquisition device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wearable electromyographic signal acquisition device comprises a neckband in the shape of a circular ring, and also comprises: two elastic V-shaped belts symmetrically arranged on both sides of the neckband, wherein both ends of the V-shaped belt are fixedly connected to the neckband, a collection piece is installed on the V-shaped belt through a sliding component, and a connecting line for transmitting data is fixedly connected to the collection piece.

[0008] In order to facilitate the adjustment of the collection position of the collection piece, preferably, the sliding assembly includes a strip groove arranged on the V-shaped belt, the strip groove faces the front end surface of the neck strap, a rubber track is fixedly connected in the strip groove, a slider is slidably connected in the rubber track, and the collection piece is fixedly connected to the slider.

[0009] In order to facilitate fixing of the slider, further, the outer wall of the slider is provided with an external thread, an internal threaded tube is threadedly connected to the external thread, and one end of the internal threaded tube is tightly pressed against the outer wall of the rubber track.

[0010] In order to facilitate the fixation of the neck strap, preferably, the neck strap is provided with an opening, and the opening of the neck strap is fixedly connected by Velcro.

[0011] In order to ensure the elasticity and breathability of the neckband and the V-shaped belt, preferably, the neckband and the V-shaped belt are made of elastic knitted fabrics.

[0012] In order to improve the air permeability of the neckband and the V-shaped belt, preferably, the neckband and the V-shaped belt are both provided with evenly distributed air holes.

[0013] In order to make the neckband fit the neck better, preferably, the diameter of the upper end of the neckband is smaller than the diameter of the lower end.

[0014] In order to make the rotation of the internally threaded tube more convenient, further, the outer wall of the internally threaded tube is provided with anti-slip grooves.

[0015] Compared with the prior art, the present invention provides a wearable electromyographic signal acquisition device, which has the following beneficial effects:

[0016] 1. The wearable electromyographic signal acquisition device uses a V-shaped belt to keep the acquisition piece close to the chest outlet. Even if the person being collected moves his muscles, the acquisition piece is unlikely to fall off, which effectively ensures the fixation and stability of the acquisition piece and indirectly improves the efficiency of electromyographic signal acquisition at the chest outlet.

[0017] 2. The wearable electromyographic signal acquisition device rotates the internal threaded tube so that the internal threaded tube is no longer pressed against the rubber track, and then pushes the slider. When the slider drives the acquisition piece to move to a suitable position, the internal threaded tube is tightened again, so that the position adjustment of the acquisition piece can be completed conveniently and quickly, thereby making the use of the entire device more flexible and convenient.

[0018] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can effectively ensure the fixation and stability of the collection piece, and indirectly improve the efficiency of collecting electromyographic signals at the thoracic outlet.
