Description

Technical Field

[0001] This utility model relates to the field of bioelectric signal detection equipment technology, specifically to a disposable EEG sensor with a cut-resistant structure. Background Technology

[0002] An electroencephalogram (EEG) sensor is a sophisticated device capable of capturing and interpreting electrical signals from the human brain. The EEG sensor works based on the weak electrical signals generated by the activity of neurons in the brain. These signals propagate through the scalp and skull, forming an electric field, which is captured by electrodes on the EEG sensor and converted into digital signals. This process includes signal acquisition, amplification, filtering, analog-to-digital conversion, and subsequent data processing and analysis. Advanced signal processing techniques effectively remove noise and interference, extracting valuable brainwave information, which is then analyzed and interpreted by software, ultimately presenting intuitive graphics or data reports.

[0003] Brain neuronal activity generates weak electrical signals, and electroencephalogram (EEG) sensors, as key devices for acquiring these signals, have wide applications in medical diagnosis, anesthesia monitoring, neuroscience research, and human-computer interaction. Disposable EEG sensors can be classified into single-chip button type, single-chip cable type, and multi-chip type according to their structure and connection method. Multi-chip type sensors typically have multiple electrodes and pre-connection connectors, which are connected to the host device's interface via connectors.

[0004] EEG sensors need to come into direct contact with human skin during use. However, current EEG sensors on the market do not adequately consider the critical safety issue of preventing patient cuts in their pre-connection connectors. In real-world applications, there are several potential risks that could cause cuts. For example, the edges of the pre-connection connectors on some sensors may not be smooth enough or the material may be too thin, potentially causing skin abrasions due to friction during contact with the patient's scalp or during adjustment.

[0005] Furthermore, the EEG sensor's pre-connection connector contains conductive lines. To prevent short circuits caused by skin contact, these lines are typically covered with an insulating coating. Some patients may be allergic to the material of this insulating coating, experiencing symptoms such as itching, redness, rashes, or even blisters after use. This not only causes discomfort but can also lead to infection if there are open wounds, further exacerbating the patient's suffering and resulting in a very poor user experience.

By incorporating a cut-resistant structure within the disposable EEG sensor to prevent direct contact between the pre-connection connector and human skin, it can prevent the pre-connection connector from cutting the user and also prevent allergies caused by the insulating coating on the pre-connection connector. This significantly improves the safety and user experience of the disposable EEG sensor and solves the problems of cuts and allergies caused by the pre-connection connector in existing disposable EEG sensors.

[0007] This utility model provides a disposable EEG sensor with a cut-resistant structure, comprising a movable EEG sensor body and a pre-connection connector.

[0010] In a further improvement to this invention, the anti-cut structure is a medical foam insulating sleeve, which tightly wraps the insulating coating.

The area of ​​the medical non-woven fabric pad layer is not less than the range of motion of the pre-connection connector.

[0012] This utility model is further improved in that a deep V-shaped notch is provided on one side edge of the medical non-woven fabric pad layer, the pre-connecting connector passes through the deep V-shaped notch, the medical non-woven fabric pad layer is divided into a pad part and a connecting part by the deep V-shaped notch, the connecting part is fixedly heat-fused to the upper surface of the EEG sensor body near the pre-connecting connector, and the pad part is closely attached to the lower surface of the pre-connecting connector and the area is not less than the range of motion of the pre-connecting connector.

[0013] In a further improvement to this invention, the main body of the electroencephalogram (EEG) sensor includes a plurality of electrode pads that are electrically connected in sequence, and at least one of the plurality of electrode pads is electrically connected to the pre-connection connector.

[0023] like Figures 1-3 As shown, this utility model provides a disposable EEG sensor with a cut-resistant structure, including an EEG sensor body 1 and a pre-connection connector 2 that are movably connected. The EEG sensor body 1 is electrically connected to the pre-connection connector 2, which can communicate with electronic devices through an external connector. The outer surface of the pre-connection connector 2 is provided with a cut-resistant structure 3 at the point of contact with human skin. The cut-resistant structure 3 is fixedly and tightly attached to the outside of the pre-connection connector 2. The cut-resistant structure 3 is made of medical non-woven fabric or medical foam. The pre-connection connector 2 includes a substrate 21, a conductive line 22, and an insulating coating 23 arranged from the inside out. The conductive line 22 is fixedly arranged on the outer surface of the substrate 21 and electrically connected to the EEG sensor body 1. The insulating coating 23 seals and covers the conductive line 22. The EEG sensor body 2 includes multiple electrode pieces that are electrically connected in sequence, and at least one of the multiple electrode pieces is electrically connected to the pre-connection connector 2. In this embodiment, the cut-resistant structure prevents direct contact between the pre-connection connector and human skin, thus preventing the connector from cutting the user and also preventing allergies caused by the insulating coating on the connector. This significantly improves the safety and user experience of the disposable EEG sensor. Furthermore, the cut-resistant structure, made of medical non-woven fabric or medical foam, greatly enhances wearing comfort, reduces the impact of discomfort on EEG signal acquisition, improves the accuracy of detection results, and enhances the durability and stability of the disposable EEG sensor.

[0024] like Figure 1As shown in the first embodiment of this utility model, the anti-cut structure 3 is a medical non-woven fabric isolation sleeve made of medical non-woven fabric, which tightly wraps the insulating coating 23. The medical non-woven fabric isolation sleeve tightly wraps the insulating coating, increasing the thickness and structural strength of the pre-connected joint. It also ensures that the material of the part of the pre-connected joint that comes into direct contact with human skin is a soft and hypoallergenic medical non-woven fabric, and that it will not cause friction damage or cuts when the pre-connected joint is bent and comes into contact with the skin.

[0025] like Figure 2 As shown in Embodiment 2 of this utility model, the anti-cut structure 3 is a medical foam insulating sleeve made of medical foam, which tightly wraps the insulating coating 23. The medical foam insulating sleeve tightly wraps the insulating coating, increasing the thickness and structural strength of the pre-connected joint. It also ensures that the part of the pre-connected joint that comes into direct contact with human skin is made of soft, non-allergenic medical foam. Furthermore, the thick medical foam is not easily bent, preventing friction damage and cuts caused by the pre-connected joint contacting the skin when bent.

[0026] like Figure 3 As shown in Embodiment 3 of this utility model, the cut-resistant structure 3 is a medical non-woven fabric pad layer made of medical non-woven fabric. The medical non-woven fabric pad layer is fixedly connected to the end of the EEG sensor body 1 near the pre-connection connector 2. The area of ​​the medical non-woven fabric pad layer is not less than the range of motion of the pre-connection connector. A deep V-shaped notch is provided on one edge of the medical non-woven fabric pad layer. The pre-connection connector passes through the deep V-shaped notch. The medical non-woven fabric pad layer is divided into a pad part and a connecting part by the deep V-shaped notch. The connecting part is fixedly heat-fused to the upper surface of the end of the EEG sensor body near the pre-connection connector. The pad part is in close contact with the lower surface of the pre-connection connector and its area is not less than the range of motion of the pre-connection connector. A medical non-woven fabric pad is fixed at the electrode plate closest to the pre-connection connector. During use, because the position of the electrode plate is fixed, the movable position of the pre-connection connector is relatively fixed, within the isolation range of the medical non-woven fabric pad. During use, the movable area of ​​the pre-connection connector is isolated from direct contact with the patient's skin by the medical non-woven fabric pad, which can prevent the pre-connection connector from cutting the user and also prevent allergies caused by the insulating coating on the pre-connection connector.

[0027] As can be seen from the above, this utility model provides a disposable EEG sensor with a cut-resistant structure. By setting a cut-resistant structure inside the disposable EEG sensor to prevent direct contact between the pre-connection connector and human skin, it can prevent the pre-connection connector from cutting the user and also prevent allergies caused by the insulating coating on the pre-connection connector. This significantly improves the safety and user experience of the disposable EEG sensor. Moreover, the cut-resistant structure made of medical non-woven fabric or medical foam can greatly enhance wearing comfort, reduce the impact of wearing discomfort on EEG signal acquisition, and help improve the accuracy of detection results. It also improves the durability and stability of the disposable EEG sensor, solving the problem of the pre-connection connector of the existing disposable EEG sensor cutting the user and causing allergies.
