Description

Technical Field

[0001] The utility model belongs to the technical field of electroencephalogram measurement, and in particular relates to an electroencephalogram electrode fixing sheet and an electroencephalogram electrode. Background Art

[0002] At present, most wearable EEG devices use dry electrodes. Compared with wet electrodes, dry electrodes have the advantages of being easy to wear, not requiring the use of conductive paste, and being suitable for non-hospital and non-laboratory environments. However, the contact impedance of dry electrodes is high. In order to obtain good EEG signals, the electrode area needs to be large and close to the skin. This requires a greater force to fix the electrode when worn, which may cause discomfort and pressure to the subject.

[0003] However, there are still some problems with the existing EEG electrodes. The existing EEG electrodes include an electrode, a columnar connecting end, and a connecting wire for connecting the electrode to the connecting end. When installing, it is necessary to apply conductive paste on the electrode and then make the conductive paste contact with the patient's skin. Then the medical staff uses tape or bandage to fix the electrode on the patient's head to complete the installation of the brain electrode. However, during the electrode installation process, in order to prevent the electrode from falling off, more tape will be used, which will cause damage to the patient's skin. At the same time, over-tightening will also cause pressure sores at the sticking position, causing secondary injuries to the patient. At the same time, in the process of sticking the electrode, the conductive paste will deviate from the established position, resulting in poor connection effect and the displaced conductive paste will also contact with the sticking surface of the tape, thereby affecting the sticking effect of the tape, which will easily cause the electrode to fall off, and then lead to the failure of the EEG measurement.

[0004] Therefore, how to complete the measurement of the patient's EEG is a problem that needs to be solved at present. Utility Model Content

[0023] After the applicant's research and analysis, the reason for this problem (electrode falling off, resulting in the failure of EEG measurement) is that the existing EEG electrode includes an electrode, a columnar connecting end, and a connecting wire for connecting the electrode to the connecting end. During installation, it is necessary to apply conductive paste on the electrode and then make the conductive paste contact with the patient's skin. Then the medical staff uses tape or a bandage to fix the electrode on the patient's head to complete the installation of the brain electrode. However, in the process of electrode installation, in order to prevent the electrode from falling off, more tape is used, which will cause damage to the patient's skin. At the same time, over-tightening will also cause pressure sores at the pasting position, causing secondary injury to the patient. At the same time, in the process of sticking the electrode, the conductive paste will deviate from the predetermined position, resulting in poor connection effect. The displaced conductive paste will also contact with the adhesive surface of the tape, thereby affecting the adhesive effect of the tape, which is easy to cause the electrode to fall off. In order to complete the measurement of the patient's EEG, the present invention includes a patch body provided with a A placement cavity, the placement cavity is used to place the electrode; a patch body, a placement cavity is provided on the patch body, the placement cavity is used to place the electrode; a hydrocolloid dressing is located on one side of the patch body and is used to stick the patch on the patient's skin; a conductive paste is located in the placement cavity and abuts against the electrode; a plastic sheet covers the adhesive surface of the hydrocolloid dressing and closes the top of the placement cavity; when sticking, the plastic sheet is torn off, and the conductive paste preset in the placement cavity is brought into contact with the patient's skin, and then the patch is stuck to the patient's brain through the hydrocolloid dressing; by using the hydrocolloid dressing, the sticking work of the electrode can be completed to avoid the electrode from falling off, and the hydrocolloid dressing has a certain decompression effect, which can reduce the pressure on the patient's skin and avoid pressure sores on the patient's head, and then by making the conductive paste located in the placement cavity, the conductive paste position can be prevented from being offset when sticking, thereby ensuring the smooth progress of the connection work, and at the same time, it can also be prevented that the offset conductive paste affects the sticking effect of the hydrocolloid dressing, thereby ensuring the smooth progress of the electroencephalogram measurement work.

[0025] The patch 1 body has a placement cavity provided thereon, and the placement cavity is used to place the electrode 6; the hydrocolloid dressing 3 is located on one side of the patch 1 body and is used to stick the patch 1 on the patient's skin; the conductive paste is located in the placement cavity and abuts against the electrode 6; the plastic sheet 2 covers the adhesive surface of the hydrocolloid dressing 3 and seals the top of the placement cavity; when sticking, the plastic sheet 2 is torn off, and the conductive paste preset in the placement cavity is brought into contact with the patient's skin, and then the patch 1 is stuck to the patient's brain through the hydrocolloid dressing 3, and a certain pressure is applied to the hydrocolloid dressing 3 to ensure that it can stick to the patient's head. In the process of applying pressure, the excess conductive paste on the electrode 6 can move to the conductive paste filling area 4, thereby avoiding contact between the conductive paste and the hydrocolloid dressing 3, thereby avoiding affecting the adhesion effect of the hydrocolloid dressing 3.

[0026] In the first embodiment, the patch 1 body is a circular structure, and the diameter of the patch 1 body is 3-4 cm.

[0029] In the fourth embodiment, an annular protrusion end is further provided on the circumference of the bottom of the electrode 6, and the annular protrusion end extends a predetermined distance toward the direction close to the plastic sheet 2, so that the distance between the electrode 6 and the patient's skin is shortened, thereby reducing the amount of conductive paste used, thereby ensuring smooth connection work.

[0030] In the fifth embodiment, the outer surface of the electrode 6, the end surface of the annular protrusion and the inner wall of the placement cavity form a conductive paste filling area 4 for placing the conductive paste; by making the conductive paste located in the conductive paste filling area 4, the adhesion effect of the hydrocolloid dressing 3 is ensured.

In the process of applying pressure, the excess conductive paste on the electrode 6 can move to the conductive paste filling area 4, thereby avoiding contact between the conductive paste and the hydrocolloid dressing 3, thereby avoiding affecting the sticking effect of the hydrocolloid dressing 3; through the action of the guide paste and the electrode 6, the collected signal can be transmitted to the EEG monitor, which is convenient for medical staff to monitor the patient.
