Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0025] As Figure 1 and Figure 2As shown, a disposable non-invasive electroencephalogram sensor includes an electroencephalogram sensor body 1 and a plug 2 for connecting a monitoring instrument, the electroencephalogram sensor body 1 and the plug 2 are connected through a wire belt 3, a protection assembly 4 is arranged on the wire belt 3, the protection assembly 4 covers the edges of the wire belt 3, and a breathable layer 42 for contacting the skin is arranged on the surface of the protection assembly 4 to isolate the wire belt 3 from the skin. Specifically, the electroencephalogram sensor body 1 and the plug 2 are connected through the wire belt 3, and the edges of the wire belt 3 are covered by arranging the protection assembly 4 on the wire belt 3, so as to prevent the sharp edges from scratching the skin of the patient and improve the safety in use. The surface of the protection assembly 4 is also provided with the breathable layer 42, which directly contacts the skin of the patient, not only achieving the isolation of the wire belt 3 from the skin, but also ensuring the comfort in use.

[0026] The utility model discloses a protection assembly 4 is set up, effectively solved the problem that the wire belt 3 edge of prior art is easy to scratch the skin of patient, improved the use comfort of patient, the breathable layer 42 not only guarantees the good contact between sensor and skin, but also improves the air permeability of use, reduces the discomfort that possibly brings of long -time wearing.

[0027] In some embodiments of the present application, as shown in Figure 3 The protection assembly 4 includes a flexible isolation sleeve 41, which is sleeved on the wire belt 3 to separate the wire belt 3 from the skin, and the breathable layer 42 is arranged on the surface of the flexible isolation sleeve 41 to contact the skin as the outer layer of the flexible isolation sleeve 41. Specifically, the flexible isolation sleeve 41, as the core part of the protection assembly 4, is sleeved on the wire belt 3, and its main function is to separate the wire belt 3 from the skin of the patient to avoid scratching the skin by the sharp edges of the wire belt 3. The breathable layer 42 is arranged on the surface of the flexible isolation sleeve 41 as the outer layer of the flexible isolation sleeve 41 to directly contact the skin of the patient; the breathable layer 42 not only ensures good adhesion between the sensor and the skin, but also improves the air permeability of use, so that the patient can also maintain a comfortable feeling when wearing for a long time. The potential harm caused by the edges of the wire belt 3 to the skin is avoided, and the safety in use of the patient is improved.

[0028] In addition, the flexible isolation sleeve 41 is directly sleeved on the wire belt 3, and the two are closely connected, which can effectively reduce the occupied area after installation of the flexible isolation sleeve 41 and avoid affecting the wearing experience of the electroencephalogram sensor. Moreover, the flexible isolation sleeve 41 is flexible, which can better cooperate with the changes of the wire belt 3 during use; it also has certain elasticity and buffering performance, which can absorb impact force when subjected to external force impact, thereby protecting the wire belt 3.

[0029] In some embodiments of the present application, the air-permeable layer 42 is provided with an adhesive surface 43 for adhering to the skin of the patient. Specifically, the adhesive surface 43 is used to adhere to the skin of the patient, thereby achieving fixation. Through the close adhesion of the adhesive surface 43 to the skin, it can be ensured that the air-permeable layer 42 is stably fixed on the skin of the patient and is not easily detached or moved, so that the brain electrical sensor body 1 can always be kept in the correct position during treatment or monitoring. Moreover, by arranging the adhesive surface 43 on the air-permeable layer 42, fixation can be achieved while ensuring good air permeability.

[0030] In some embodiments of the present application, as shown in Figure 4 The adhesive surface 43 has a plurality of adhesive surfaces 43, and the plurality of adhesive surfaces 43 are arranged at intervals along the length direction of the lead tape 3. Specifically, the plurality of adhesive surfaces 43 are arranged at intervals, which can increase the fixed points of the lead tape 3 on the skin, thereby improving the stability of fixation and reducing the risk of detachment or displacement. Moreover, compared with a single large-area adhesive surface 43, the plurality of adhesive surfaces 43 arranged at intervals achieve better air permeation effect.

[0031] In some embodiments of the present application, the material of the flexible isolation sleeve 41 is rubber material. Specifically, the rubber material is neoprene, nitrile rubber, or ethylene-propylene-diene rubber.

[0032] In some embodiments of the present application, the flexible isolation sleeve 41 is detachably connected with the lead tape 3. Specifically, the flexible isolation sleeve 41 is detachably arranged on the lead tape 3, so that in special cases, for example, when the air-permeable layer 42 accidentally sticks to liquid or medicine during use, the flexible isolation sleeve 41 can be detached from the lead tape 3, and a new flexible isolation sleeve 41 can be replaced. This not only ensures the effective separation of the flexible isolation sleeve 41 from the lead tape 3, but also facilitates the user to detach and replace the flexible isolation sleeve 41 as needed.

[0033] In some embodiments of the present application, as shown in Figure 5 The flexible isolation sleeve 41 includes a base body 411, and the opposite sides of the base body 411 are respectively provided with a double-sided adhesive portion 412 and a connecting portion 413. After the base body 411 covers the lead tape 3, one side of the double-sided adhesive portion 412 is adhered to the lead tape 3, and the other side is adhered to the connecting portion 413, so as to form a sleeve structure. Specifically, when the flexible isolation sleeve 41 is assembled to the lead tape 3, first, the base body 411 is covered on the lead tape 3; then one side of the double-sided adhesive portion 412 is adhered to the lead tape 3, and the other side is adhered to the connecting portion 413. Through this adhesion mode, the two ends of the base body 411 are tightly combined together through the double-sided adhesive portion 412 and the connecting portion 413, forming a sleeve structure, which completely wraps the lead tape 3 inside. In turn, the lead tape 3 is isolated, avoiding potential harm to the skin caused by the edges of the lead tape 3 when using the brain electrical sensor, and improving the safety of the patient in use.

[0034] In some embodiments of the present application, a pull tape 414 is further included, both ends of the pull tape 414 pass through the air-permeable layer 42 and are connected with the connecting part 413, so that the user can pull the connecting part 413 away from the double-sided adhesive layer through the pull tape 414. Specifically, when it is necessary to remove or replace the flexible isolation sleeve 41, the user can operate through the pull tape 414; by pulling the pull tape 414, the connecting part 413 can be pulled away from the double-sided adhesive layer; then the base body 411 is pulled to separate the double-sided adhesive layer from the wire belt 3, so that the removal of the flexible isolation sleeve 41 is completed. Compared with directly tearing or cutting the isolation sleeve, the use of the pull tape 414 can make the removal work more easily and quickly, so that the process of removing the flexible isolation sleeve 41 is more rapid and efficient.

[0035] In some embodiments of the present application, the material of the air-permeable layer 42 is cotton material. Specifically, the air-permeable layer 42 made of cotton material is relatively soft and can be more closely contacted with the skin, so as to avoid scratching the skin during use. The cotton fiber of the cotton material is long and soft, and there are a large number of micropores and gaps between the fibers, which provide a channel for air flow. When the human body generates heat or moisture, the cotton air-permeable layer 42 can quickly discharge the heat and moisture outside the body, keeping the skin dry and comfortable. Especially in the case of long-term wearing, the cotton air-permeable layer 42 can significantly reduce the problems of skin discomfort and allergy.

[0036] In some embodiments of the present application, the electroencephalogram sensor body 1 includes a first electrode chip assembly 11, a second electrode chip assembly 12, a third electrode chip assembly 13 and a fourth electrode chip assembly 14, the first electrode chip assembly 11, the second electrode chip assembly 12, the third electrode chip assembly 13 and the fourth electrode chip assembly 14 are connected through a flexible connecting belt, and the wire belt 3 is connected with the first electrode chip assembly.

[0037] It should be noted that the use process of the present disposable non-invasive electroencephalogram sensor is as follows: the electroencephalogram sensor is taken out from the package, and the first electrode chip assembly 11, the second electrode chip assembly 12, the third electrode chip assembly 13 and the fourth electrode chip assembly 14 of the sensor body are placed at the corresponding positions of the head; the electroencephalogram sensor is lightly pasted on the scalp to ensure that the electrodes are in close contact with the scalp; the plug is inserted into the corresponding interface of the lead to ensure that the electroencephalogram sensor is correctly connected with the electroencephalogram monitoring device; during the monitoring process, the software will record the electroencephalogram data in real time, and the user can set the time range of data acquisition according to needs; after the data acquisition is completed, the electroencephalogram sensor is removed from the scalp, and since it is a disposable product, the removed electroencephalogram sensor should be disposed in accordance with the medical waste treatment regulations.
