Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary appliances, and in particular relates to an integrated magnetic video electroencephalogram electrode line quick fixing device. Background Art

[0002] Video EEG is an extension of EEG technology. It can record EEG development and corresponding EEG changes for a long time. It is a method used to diagnose epilepsy. Therefore, by using video EEG, lesions and abnormal EEG changes that are not found in conventional EEG can be shown. During the examination, multiple electrode wires will be connected to multiple predetermined points on the patient's head. The electrode wires will be fixed, and then the patient's brain wave response can be monitored in real time through an external video.

[0003] However, in the prior art, when conducting an EEG examination, all electrode wires are generally connected to the EEG cap first, and then the EEG cap is worn on the head so that the electrodes are distributed on various detection points on the head, and then the electrodes are fixed externally with gauze. However, when installing and removing the electrodes, they need to be disassembled one by one. The disassembly of a large number of electrodes brings a workload to medical staff and is more troublesome to operate. Therefore, in response to the above problems, we propose an integrated magnetic video EEG electrode wire quick fixing device. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide an integrated magnetic video EEG electrode wire quick fixing device, which is convenient for quickly disassembling and assembling multiple electrodes during use, bringing convenience to the work of medical staff.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated magnetic video EEG electrode wire quick fixing device, comprising a positioning plate and an electrode wire, a fixing cap being provided on the positioning plate, a plurality of electrode wires, each of which comprises a wire and an electrode connected to the wire, and each of the wires passes through the positioning plate, an elastic strip being provided on the outer wall of one end of the wire close to the electrode, an end of the elastic strip away from the electrode being connected to the positioning plate, and an end of the wire away from the electrode being connected to an EEG detection device.

[0006] The beneficial effects of the utility model are as follows: by placing the positioning plate above the head and then pressing the positioning plate downward, the elastic strip follows the movement of the positioning plate, so that the electrodes are located on multiple detection points. When they are in contact with each detection point, the fixing cap is put on the head to fix the positions of multiple electrodes at the same time. When disassembly is required, the fixing cap is turned outward and the fixing cap and the multiple electrodes are removed together, which brings convenience to the work of medical staff.

[0007] To increase patient safety and comfort;

[0008] As a further improvement of the above technical solution: a plurality of the electrodes are provided with protective rings, and when the electrodes inspect the head detection point, the protective rings are located between the electrodes and the head detection point.

[0009] The beneficial effects of this improvement are: the provision of the protective ring can prevent direct contact between the electrode and the head detection point, can avoid pressure sores caused by long detection time, and increase the safety and comfort of the patient.

[0010] To facilitate adjustment to different head sizes;

[0011] As a further improvement of the above technical solution: an adjusting rod is threadedly connected to the positioning plate, and the adjusting rod is used to adjust the distance between the positioning plate and the head.

[0012] The beneficial effect of this improvement is: by gradually bringing the positioning plate closer to the head, the electrode first contacts the head. As the positioning plate approaches, when the patient's head is small, when the electrode moves to the position of contacting the head detection point, the positioning plate may not be in contact with the head. At this time, by rotating the adjustment rod so that the adjustment rod contacts the head, and then fixing the fixing cap on the head, the electrode can be fixed for patients with smaller heads, thereby improving the flexibility of use.

[0013] In order to facilitate the storage of wires;

[0014] As a further improvement of the above technical solution: a cover portion is provided on the positioning plate, and a wire bundle channel is formed between the positioning plate and the cover portion, and the plurality of wires pass through the wire bundle channel and extend to the outside of the cover portion.

[0015] The beneficial effect of this improvement is that since there are more detection points during EEG detection, there are also more wires, and the distribution of more wires on the head is more chaotic. By passing all the wires through the wire bundle channel, all the wires can be stored and organized.

[0016] To increase patient comfort;

[0017] As a further improvement of the above technical solution: a protective portion is provided at one end of the adjusting rod close to the head.

[0018] The beneficial effect of this improvement is that the setting of the protective part can ensure that when the adjusting rod contacts the head, the protective part contacts the head first, avoiding direct contact between the protective part and the head, thereby increasing the patient's comfort.

[0019] In order to increase the stability of the electrode;

[0020] As a further improvement of the above technical solution: two adjustment straps are symmetrically provided on the fixing cap, and the two adjustment straps are connected by a connecting piece.

[0021] The beneficial effect of this improvement is that after the fixing cap is fixed, the two adjustment straps are wrapped around the patient's chin to make contact, and are adjusted and fixed through the connecting piece according to the patient's condition. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, an integrated magnetic video EEG electrode wire quick fixing device includes a positioning plate 1 and an electrode wire. The positioning plate 1 is provided with a fixing cap 2. The electrode wires are multiple, each of which includes a wire 302 and an electrode 301 connected to the wire 302. The wires 302 all pass through the positioning plate 1. An elastic strip 4 is sleeved on the outer wall of one end of the wire 302 close to the electrode 301. The end of the elastic strip 4 away from the electrode 301 is connected to the positioning plate 1. The end of the wire 302 away from the electrode 301 is connected to the EEG detection device.

[0030] Specifically, the elastic strip 4 can be made of a material with a certain elasticity such as a metal strip or a plastic strip, and the surface of the elastic strip 4 is smooth. When in use, the positioning plate 1 is moved toward the middle of the head. As the positioning plate 1 approaches the head, the electrode 301 will first contact the head, and then the electrode 301 will slide down on the surface of the head. When the electrode 301 slides to the position of the detection point, the positioning plate 1 contacts the head. At the same time, under the elastic action of the elastic strip 4, the electrode 301 will also be close to the patient's head. Then, the fixing cap 2 is initially flipped outward, and can be When the electrode 301 is moved, it is convenient to observe whether the position of the electrode 301 is correct. After the position of the electrode 301 is fixed, the fixing cap 2 is turned down and fits against the head. The fixing cap 2 is made of an elastic, skin-friendly and breathable material. Under the action of the elastic material of the fixing cap 2, the electrode 301 is fixed and fit, and then the wire 302 is connected to the electroencephalogram detection equipment for detection. When the detection is completed, the fixing cap 2 and the electrode 301 can be removed together. It is easy to disassemble and assemble, which brings convenience to the work of medical staff.

[0031] Preferably, a protective ring 5 is provided on each of the plurality of electrodes 301. When the electrode 301 inspects the head detection point, the protective ring 5 is located between the electrode 301 and the head detection point. The protective ring 5 can be made of rubber, silicone or other materials. The setting of the protective ring 5 can prevent the electrode 301 from directly contacting the head detection point, avoid pressure sores caused by too long detection time, and increase the safety and comfort of the patient.

[0032] Preferably, an adjusting rod 6 is threadedly connected to the positioning plate 1, and the adjusting rod 6 is used to adjust the distance between the positioning plate 1 and the head. By gradually moving the positioning plate 1 closer to the head, the electrode 301 first contacts the head. As the positioning plate 1 approaches, when the patient's head is small, when the electrode 301 moves to the position of contact with the head detection point, the positioning plate 1 may not contact the head. At this time, by rotating the adjusting rod 6 to make the adjusting rod 6 contact the head, and then fixing the fixing cap 2 on the head, the electrode 301 can be fixed to the patient with a smaller head, thereby improving the flexibility of use.

[0033] Preferably, a cover portion 7 is provided on the positioning plate 1, and a wiring channel 8 is formed between the positioning plate 1 and the cover portion 7. The plurality of wires 302 pass through the wiring channel 8 and extend to the outside of the cover portion 7. Since there are more detection points during EEG detection, there are also more wires 302. The distribution of more wires 302 on the head is more chaotic. By passing all the wires 302 through the wiring channel 8, all the wires 302 can be stored and organized.

[0034] Preferably, a protective part 9 is provided at one end of the adjusting rod 6 close to the head, wherein the protective part 9 may be made of rubber, silicone or the like. The setting of the protective part 9 allows the protective part 9 to contact the head first when the adjusting rod 6 contacts the head, thereby avoiding direct contact between the protective part 9 and the head and increasing the patient's comfort.

[0035] Preferably, two adjustment straps 10 are symmetrically provided on the fixing cap 2, and the two adjustment straps 10 are connected by a connector 11, wherein the connector 11 can be a structure such as Velcro, a snap buckle, etc. When the fixing cap 2 is fixed, the two adjustment straps 10 are wrapped around the patient's chin to make contact, and are adjusted and fixed through the connector 11 according to the patient's condition.

[0036] The working principle and usage process of the present invention are as follows: when using the device, first hold the adjusting rod 6 and drive the positioning plate 1 close to the middle of the head. Then, as the positioning plate 1 approaches the head, the electrode 301 will first approach the head and make the protective ring 5 contact the head. Then, the electrode 301 slides down on the surface of the head. When the electrode 301 slides to the position of the detection point, the adjusting rod 6 is rotated so that the protective part 9 at one end of the adjusting rod 6 touches the head. Then, the fixing cap 2 is flipped down to fit the head. The two adjusting straps 10 are passed around the chin and then adjusted and fixed through the connecting piece 11. Finally, each wire 302 is connected to the EEG detection equipment for detection. When the detection is completed, the two adjusting straps 10 are separated, and the fixing cap 2 is turned outward. The positioning plate 1 is picked up and all the electrodes 301 can be removed together. It is convenient to quickly disassemble and assemble multiple electrodes 301 during use, which brings convenience to the work of medical staff.
