Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, and specifically relates to an anti-tangling storage device for electromyography detection circuits. Background Technology

[0002] Electromyography (EMG) can be used for the diagnosis of neuromuscular diseases and rehabilitation assessment. Current EMG devices typically have three electrodes attached to the skin and one stimulator on the skin surface. Each electrode and stimulator has a lead at the back, requiring repeated use of the electrodes and stimulator when diagnosing different patients continuously. The patient must be on the treatment bed, and a sufficiently long lead, typically 1-3 meters, is needed between the EMG device and the patient. Therefore, during routine operation, the four winding leads often become tangled, easily forming a mess if not combed. Over time, this tangled wiring can damage the signal and affect its stability.

[0003] The prior art discloses a grounding wire winding device for grounding resistance, with the publication number CN117023277A. The annular grounding wire winding ring 1 of the winding device can wind and store the conductor 6 in a ring shape. After the conductor is stacked for a certain period of time, the annular winding and stored conductor is released again, and the conductor is easy to bend into a uniform coil shape without straightening the conductor.

[0004] The four wires, which are coiled up, tend to curl into a uniform, coiled shape when unwound. They are also easy to twist. When performing electromyography (EMG) tests on multiple patients daily, the wires are easily tangled together when used repeatedly in the same area. The wires are difficult to untangle, making the testing process inconvenient. Utility Model Content

[0005] This invention provides an anti-tangling storage device for electromyography (EMG) detection circuits to solve the aforementioned technical problems of easy tangling and difficulty in combing the wires when repeatedly used for EMG testing.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an anti-tangling storage device for electromyography (EMG) detection circuits, characterized in that it includes:

[0007] The hanging body has a threaded buckle at the rear and a rotating bar at the front.

[0008] The unit boxes are evenly placed on the rotating rod of the hanging body in a rotating connection manner. The unit boxes are respectively provided with inlet and outlet ports, and the sliding tracks are evenly provided on both sides of the unit boxes.

[0009] The stationary reel assembly is evenly placed on the upper side inside the unit box in a bolted connection manner;

[0010] A movable pulley block is placed in the slide rail of the unit box in a sliding fit. A wire is evenly wound between the movable pulley block and the stationary pulley block. A tension spring is also provided between the movable pulley block and the bottom of the unit box.

[0011] A wire stopper is placed at the end of the wire outlet of the unit box, and the wire stopper locks the wires extending out of the wire outlet.

[0012] Preferably, both the stationary pulley group and the movable pulley group are pulley-shaped, and there are 6 of each group. The stationary pulley group is placed inside the upper part of the unit box and arranged in a straight line.

[0013] Preferably, the slides on both sides of the unit box are symmetrically distributed, with 6 slides on each side of the unit box, and a movable pulley group is provided in each of the symmetrically distributed slides.

[0014] Preferably, the slides are all arranged in a parallel vertical distribution, the movable pulley group slides back and forth in the vertical direction within the slide, and a movable pulley group is placed below each of the two adjacent stationary pulley groups. The conductor passes through the movable pulley group and the stationary pulley group in sequence, and the conductor can be evenly distributed in a V-shape or W-shape after passing through the movable pulley group and the stationary pulley group in sequence.

[0015] Preferably, the number of tension springs is twice the number of movable pulley groups, and each movable pulley group has a tension spring hanging on both sides of its shaft end. The tension of the tension springs pulls the movable pulley group away from the stationary pulley group.

[0016] Preferably, the number of unit boxes is 4, and all 4 unit boxes are rotatably connected to the rotating lever. Each unit box can be manually raised or lowered around the rotating lever. The number of wires is 4, and the 4 wires are evenly distributed in the 4 unit boxes.

[0017] Preferably, the number of the line stoppers is 4, and one line stopper is provided on the outlet of each unit box.

[0018] Preferably, the line stopper includes a gate slot, a gate clamp plate, a slide rod, a column spring, a pressure cap, and a pull ring handle. The gate slot is bolted into the outlet. The lower end of the slide rod is bolted to the gate clamp plate, and the upper end of the slide rod is threaded to the pull ring handle. The column spring is sleeved on the outside of the slide rod and threaded to the upper outer shell of the outlet through the pressure cap. The column spring is compressed inside the pressure cap and pushes the gate clamp plate towards the gate slot.

[0019] Preferably, the inner surface of the gate slot and the inner surface of the gate clamp are both serrated ridges. The wire passes through the interior between the gate slot and the gate clamp, and the column spring holds the gate clamp to clamp the wire in the gate slot for a clamping lock.

[0020] The beneficial effects of this utility model are as follows: This utility model uses a stationary pulley set placed on the upper inner side of the unit box, and a movable pulley set placed on the lower inner side of the unit box. Each unit box contains only one wire. The staggered movable and stationary pulley sets allow the wires in the unit box to be folded in a W-shape and stored. When a wire is needed, the stop clamp can be lifted, and the wire can be pulled out to the appropriate length manually. The wires are less likely to curl after passing through the movable and stationary pulley sets, and the pulled-out wires are less likely to twist. Furthermore, the four wires can be placed in the four unit boxes respectively, and the wires are less likely to get mixed up or tangled. At the same time, the pulled-out wires are evenly distributed. Compared with the traditional method, the four wires have excellent combinability, making them easy for medical staff to use repeatedly every day. The four wires are less likely to get tangled, and when storing the four wires, they can be directly put into each unit box. When using them, they are easy to pull out, and can be pulled out quickly by hand. The convenience of use is excellent. Attached Figure Description

[0031] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] Reference Figures 1 to 7 As shown, one aspect of this utility model provides an anti-tangling storage device for electromyography (EMG) detection circuits, including a hanging body 1, a unit box 2, a stationary wire pulley group 3, a movable pulley group 4, a wire 5, and a wire stopper 7.

[0034] The following text will describe in detail some of the structure and principles of the above-mentioned components according to this storage device.

[0035] As an example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the hanging body 1 can be made of plastic or metal. The rear of the hanging body 1 is provided with a threaded buckle 11, which can be in the form of a pressure plate. Two threaded buckles 11 can be used to firmly press and connect the hanging body 1 to the cylindrical armrest of the electromyography detection device, ensuring a stable connection between the external hanging body 1 and the electromyography detection device.

[0036] The front of the hanging body 1 is provided with a rotating rod 12, which can be a columnar shaft and can be bolted to the front end of the hanging body 1. Unit boxes 2 are evenly placed on the rotating rod 12 of the hanging body 1 in a rotatable connection. Four unit boxes 2 can be evenly distributed on the rotating rod 12 of the hanging body 1, and each unit box 2 has the same structure. Manually lifting the bottom of the unit box 2 allows it to rotate around the rotating rod 12, facilitating manual maintenance during subsequent cable handling. Furthermore, each unit box 2 contains one wire 5, and the four unit boxes 2 respectively hold four wires 5, making wire management convenient and neat.

[0037] Each unit box 2 is provided with an inlet 21 and an outlet 22. One end of the wire 5 extends from the inlet 21. In practical applications, the wire 5 extending from the inlet 21 can be securely connected to the inlet 21 using an adhesive plastic block to prevent the wire 5 from moving within the inlet 21. The other end of the wire 5 extends from the outlet 22. Each unit box 2 has evenly distributed slides 23 on both sides. The slides 23 can be milled into elongated holes. The slides 23 on both sides of the unit box 2 are symmetrically distributed, with 6 slides on each side. A movable pulley group 4 is installed within each of the symmetrically distributed slides 23. The slide rails 23 are all arranged in a parallel vertical distribution. The movable pulley group 4 slides back and forth vertically within the slide rails 23. The movable pulley group 4 is placed within the slide rails 23 of the unit box 2 in a sliding fit. A tension spring 6 is also provided between the movable pulley group 4 and the bottom of the unit box 2. The tension spring 6 can be a tension spring with a thinner diameter spring wire, and the tension force to straighten the wire 5 is sufficient to meet the design requirements. The number of tension springs 6 is twice the number of movable pulley groups 4. Each movable pulley group 4 has a tension spring 6 hanging on both sides of the shaft end, ensuring that the two identical tension springs 6 can balance the downward tension applied by the movable pulley group 4 within the slide rail 23.

[0038] The stationary wire reel assembly 3 is bolted together and evenly placed on the upper side inside the unit box 2. Both the stationary wire reel assembly 3 and the movable pulley assembly 4 are pulley-type winding reels, and there are six of each. The stationary wire reel assembly 3 is placed inside the unit box 2 on the upper side and arranged in a straight line. The stationary wire reel assembly 3, located adjacent to the outlet 22, can smoothly guide the wire 5 out of the outlet 22.

[0039] Reference Figure 3 As shown, a movable pulley group 4 is placed below each of the two adjacent stationary pulley groups 3. The wire 5 passes sequentially around the movable pulley group 4 and the stationary pulley group 3, and the wire 5 can be evenly distributed in a V-shape or W-shape after passing through the movable pulley group 4 and the stationary pulley group 3. The wire 5 is evenly wound between the movable pulley group 4 and the stationary pulley group 3. The tension of the tension spring 6 pulls the movable pulley group 4 away from the stationary pulley group 3, so that the wire 5 is evenly straightened, ensuring that the wire 5 can be neatly stored in a folded shape inside the unit box 2.

[0040] Reference Figures 1 to 7 As shown, each of the unit boxes 2 can be provided with a wire stopper 7 at its outlet 22. There are 4 wire stoppers 7, and each wire stopper 7 can lock the wire 5 extending from the outlet 22 below it.

[0041] Specifically, the line stopper 7 includes a gate groove 71, a gate clamp plate 72, a sliding rod 73, a column spring 74, a pressure cap 75, and a pull ring handle 76. The gate groove 71 can be a groove made of rubber material and can be bolted to the lower side of the inner wall of the outlet 22. The gate clamp plate 72 can be a rectangular plate made of metal plate with rubber material glued to the outside. The gate clamp plate 72 can be placed in the gate groove 71 with a clearance fit. The lower end of the sliding rod 73 is bolted to the gate clamp plate 72, and the upper end of the sliding rod 73 is threaded to the pull ring handle 76. The column spring 74 can be sleeved on the outside of the sliding rod 73 and threaded to the upper outer shell of the outlet 22 through the pressure cap 75. The column spring 74 is compressed in the pressure cap 75 and pushes the gate clamp plate 72 towards the gate groove 71. The column spring 74 makes the gate clamp plate 72 and the gate groove 71 form a clamping closure.

[0042] Reference Figure 5As shown, the wire 5 passes through the interior between the gate slot 71 and the gate clamp 72. Both the inner surfaces of the gate slot 71 and the gate clamp 72 have serrated edges to ensure that the wire 5 pulled out from the outlet 22 will not retract into the unit box 2, thus preventing the tension of the tension spring 6 from pulling the extended wire 5 back into the unit box 2. The column spring 74 clamps the gate clamp 72 against the gate slot 71, locking the wire 5 within the gate slot 71 in a clamping manner.

[0043] In this embodiment, when the wire 5 is not in use, it can be stored in its respective unit box 2. During testing, after the device is turned on, the required length of wire 5 can be manually pulled out according to the testing location requirements. After the test is completed, the pull ring handle 76 is manually pulled up to disengage the gate clamp 72 from the gate slot 71, and the wire 5 can be pulled back into the unit box 2 for storage by the pull of the tension spring 6.

[0044] This invention employs a stationary pulley group 3 placed on the upper inner side of the unit box 2, and a movable pulley group 4 placed on the lower inner side of the unit box 2. Each unit box 2 contains only one wire 5. The staggered movable pulley group 4 and stationary pulley group 3 allow the wire 5 in the unit box 2 to be folded into a W-shape and stored. When the wire 5 is needed, the clamp plate 72 of the wire stopper 7 can be lifted, and the wire 5 can be pulled out to a suitable length manually. The wire 5 is not prone to curling after being rolled by the movable pulley group 4 and stationary pulley group 3, and the pulled-out wire 5 is not prone to twisting. Furthermore, the four wires 5 can be placed in the four unit boxes 2 respectively, and the wires 5 are not prone to confusion and tangling. At the same time, the pulled-out wires 5 are evenly distributed. Compared with the traditional method, the four wires 5 have excellent combability, making it easy for medical personnel to use them repeatedly every day. The four wires 5 are not prone to tangling. When storing the four wires 5, they can be directly put into each unit box 2. When using them, they are easy to pull out and can be pulled out quickly by hand, making them extremely convenient to use.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this invention. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
