Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a dual electroencephalogram monitoring device. Background Art

[0002] Electroencephalograph is an essential instrument for diagnosing neurological diseases and is also commonly used in clinical anesthesia monitoring and intensive care units. Electroencephalographs are usually composed of EEG detection electrodes, EEG wires, amplifiers, display units, host computers, etc. They are used to extract, amplify, filter, record, analyze, and replay EEG signals, so as to analyze and diagnose patients' mental diseases and substantial brain lesions, and evaluate brain function status.

[0003] At present, EEG monitoring usually requires testing three points: the center of the forehead, the center of the eyebrows and the temple. If both sides of the face are monitored together, there are six points at the same time. However, the existing EEG detection electrodes can only detect one point at a time, which leads to the need for multiple detection electrodes during EEG monitoring. They need to be sucked onto the patient's face one by one, resulting in cumbersome operation and the lines of multiple detection electrodes are prone to entanglement. Utility Model Content

[0004] In order to make up for the deficiencies in the prior art, the utility model provides a dual EEG monitoring device which integrates multiple detection electrodes into one, has convenient and quick monitoring operation, and the lines are not easy to be entangled and are firmly fixed.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A dual EEG monitoring device comprises two connected half-moon-shaped electrode sheets, a head fixing strap and a mandibular fixing strap, wherein the electrode sheet is provided with three detection electrodes, which respectively correspond to the positions of the forehead, the eyebrows and the temples of the human face, and the three detection electrodes are led out from the electrode sheet through separate lines, the head fixing strap is connected to the other ends of the two electrode sheets, and the mandibular fixing strap is connected to both ends of the head fixing strap.

[0007] Furthermore, the lengths of the head fixing strap and the chin fixing strap are adjustable.

[0008] Furthermore, the head fixing strap and the chin fixing strap are formed by two straps connected by a Japanese buckle.

[0009] Furthermore, a chin pad is provided on the mandibular fixing belt.

[0010] Furthermore, it also includes a display, wherein the display is provided with two monitoring value display areas and one average value display area.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] The dual EEG monitoring device of the utility model integrates three detection electrodes on a half-moon shaped electrode sheet, and can complete the monitoring of multiple points with only one operation, which is convenient and quick to use; it also reduces the entanglement of the detection electrode circuit, making it easier to store and organize; in addition, the electrode sheet can be conveniently and securely fixed to the patient's face through the head fixing strap and the mandibular fixing strap, avoiding the risk of falling off during the monitoring process.

[0017] Many specific details are described in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from the description, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Example 1

[0019] like Figure 1 , 2 As shown, a dual EEG monitoring device includes two connected half-moon-shaped electrode sheets 1, a head fixing strap 2 and a mandibular fixing strap 3. The two electrode sheets 1 are used to monitor the left forehead and the right forehead respectively. Three detection electrodes 4 are arranged in each electrode sheet, and the three detection electrodes 4 correspond to the positions of the forehead, the eyebrows and the temples of the human face respectively. The three detection electrodes 4 are led out from the electrode sheet 1 through separate lines. The electrode sheet 1 adopts a half-moon-shaped design, so that its adhesion area with the skin is larger and it is not easy to get loose during use. The detection electrodes at three points are integrated in one electrode sheet, which can reduce the winding or tangling of the lines compared with the traditional method, and is easier to organize.

[0020] The electrode sheet 1 adopts a hydrophilic dressing, which has the advantages of oil resistance, moisture resistance, and interference resistance, and will not have side effects on the skin. For patients who need long-term treatment, the electrode sheet can be disassembled and cleaned if it is stained, and can be reused, which is convenient and quick to reduce the burden on patients.

[0021] The head fixing strap 2 is connected to the other ends of the two electrode sheets 1, so that the electrode sheets 1 can be worn on the head. The chin fixing strap 3 is connected to the two ends of the head fixing strap 2, and can be worn on the chin to fix the electrode sheets 1. The lengths of the head fixing strap 2 and the chin fixing strap 3 can be adjusted. Specifically, the head fixing strap 2 and the chin fixing strap 3 are formed by two straps connected by a Japanese buckle; thus, the tightness can be adjusted according to the patient's head circumference and face size. The chin fixing strap 3 is provided with a chin pad 5, which can buffer the chin and improve the comfort of use.

[0022] In addition, if Figure 3 As shown, a display 6 connected to the electrode sheet 1 is also provided. The display 6 is provided with two monitoring value display areas 61, one on the left and one on the right, for respectively displaying the monitoring values ​​and waveforms of the two electrode sheets 1. Between the two monitoring value display areas 61 is an average value display area 62, for displaying the average value of the monitoring values ​​of the two electrode sheets 1, which can be a more effective basis for clinical practice. The display can also set the upper and lower limits of the parameter alarm, and issue an alarm when the limit is exceeded. The display also has an automatic calibration function. When the monitoring values ​​on the left and right sides differ greatly, it can be automatically calibrated to make the monitoring more accurate.

[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
