Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroencephalography (EEG) auxiliary devices, and in particular to an EEG electrode fixing adhesive tape for preventing pressure sores. Background Technology
[0002] Electroencephalography (EEG) is a diagnostic method that uses electrodes to record the spontaneous discharges of cell populations, amplifying and converting weak bioelectrical signals into digital curves to aid in the diagnosis of brain diseases. Data acquisition is a crucial step in scalp EEG examinations. High scalp impedance and electrode detachment are common factors affecting electrode signal quality during the examination, significantly impacting the quality of subsequent EEG data and the accuracy of the results.
[0003] Clinically, sleep analysis, epileptogenic focus assessment, consciousness status assessment in patients with chronic disorders of consciousness, and critical EEG monitoring typically require medium- to long-term video EEG recordings, usually ranging from 4 hours to several days of continuous monitoring. To ensure signal quality during continuous monitoring, it is essential to minimize scalp impedance and effectively secure the electrodes. Technicians usually treat the scalp with scrub and alcohol before placing the electrodes, then tightly cover the treated scalp area and apply pressure using elastic netting caps and bandages. Because the protective keratin layer on the scalp is removed after treatment, prolonged pressure on the electrodes in the treated scalp area can easily cause pressure sores, potentially leading to local skin ulceration. Clinically, infants and bedridden patients are high-risk groups for adverse events such as scalp injury. Reducing the pressure of the securing netting and bandages can easily cause electrode detachment, displacement, or poor contact due to the patient's physical movements during the examination, resulting in reduced data validity or even examination failure.
[0004] Therefore, a device is needed that can both ensure that the electrodes can effectively collect EEG signals without shifting and effectively alleviate the pressure of the electrodes on the scalp to solve the above problems.
[0005] How to solve the above problems has become an urgent technical issue. Utility Model Content
[0006] The purpose of this invention is to provide an anti-pressure sore EEG electrode fixing tape, which can effectively fix the electrode to the scalp and effectively reduce the pressure of the electrode on the skin, thus reducing pressure injury.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] This utility model provides an anti-pressure sore electroencephalogram electrode fixing adhesive tape, comprising:
[0009] The adhesive tape body has an adhesive side that comes into contact with human skin.
[0010] A pressure-reducing pad is fixedly disposed on the adhesive surface of an adhesive tape body, and the side of the pressure-reducing pad away from the adhesive tape body has a notched receiving groove, into which an electrode can be detachably attached; and,
[0011] The side of the pressure-reducing pad away from the adhesive pad is flush with the side of the electrode that mates with the human skin.
[0012] Furthermore, it also includes at least one through hole, which sequentially penetrates the adhesive tape body, the pressure-reducing pad, and communicates with the receiving groove.
[0013] Furthermore, the receiving groove is racket-shaped, including a groove head and a groove tail, wherein the groove head is coaxial with the through hole, and the two ends of the groove tail are respectively connected to the groove head and the notch.
[0014] Furthermore, the receiving groove is circular and coaxial with the through hole.
[0015] Furthermore, it also includes release paper, which overlaps and is bonded to the adhesive surface of the adhesive tape, and the area of the release paper is larger than the area of the adhesive tape; and the pressure-reducing pad and the receiving groove are both located between the release paper and the adhesive tape.
[0016] Furthermore, the areas of the adhesive tape body, the pressure-reducing pad, and the receiving groove decrease in size sequentially.
[0017] Furthermore, the side of the pressure-reducing pad away from the adhesive cloth body and the bottom surface of the receiving groove are both provided with an adhesive layer.
[0018] Furthermore, a buffer layer is provided on the side of the adhesive tape away from the pressure-reducing pad.
[0019] Furthermore, the adhesive tape body is a non-woven adhesive tape, and the pressure-reducing pad and the buffer layer are both foam.
[0020] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:
[0021] This invention incorporates a pressure-reducing pad, which is fixedly placed on the adhesive surface of the adhesive tape. The pad has a notched receiving groove. During use, the electrode is adhered and fixed in the receiving groove. At this time, the side of the pressure-reducing pad away from the adhesive tape is flush with the side of the electrode that mates with the skin. This not only fixes the electrode, reduces displacement, and ensures good acquisition of EEG signals, but also effectively distributes the pressure applied by the elastic cap or bandage onto the patient's scalp, effectively avoiding excessive local pressure and thus reducing the pressure of the electrode on the skin, reducing pressure injury.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Example 1
[0031] Please refer to Figures 1 to 3 This embodiment provides an anti-pressure sore electroencephalogram electrode fixation tape, comprising:
[0032] Adhesive tape body 1, wherein the side of the adhesive tape body 1 that contacts human skin is an adhesive side;
[0033] A pressure-reducing pad 2 is fixedly disposed on the adhesive surface of the adhesive tape body 1. Furthermore, the side of the pressure-reducing pad 2 away from the adhesive tape body 1 has a receiving groove 3 with a notch 6, into which the electrode can be detachably attached; and...
[0034] The side of the pressure-reducing pad 2 away from the adhesive tape 1 is flush with the side of the electrode that fits against the human skin. This allows the pressure-reducing pad 2 to provide some support for the electrode through the adhesive tape 1, while also preventing gaps from forming between the electrode and the skin, ensuring that the electrode can make good contact with the skin.
[0035] In use, the electrode is placed in the receiving groove 3 with the side of the electrode away from the human skin glued to the receiving groove 3. The wire connecting the electrode passes through the notch 6 and out of the receiving groove 3 to connect to the electroencephalogram machine, so that the electrode can be fixed on the patient's head. The side of the pressure relief pad 2 away from the adhesive tape body 1 presses against the scalp, thereby providing a certain support for the electrode. The pressure applied by the elastic net cap or bandage is transmitted to the electrode in sequence through the adhesive tape body 1 and the pressure relief pad 2, which can avoid excessive local pressure, thereby reducing the pressure of the electrode on the skin and reducing pressure injury.
[0036] Optionally, the pressure-reducing pad 2 is sewn, welded, or bonded to the adhesive cloth body 1; the thickness of the pressure-reducing pad 2 is 4-5 mm, for example, the thickness of the pressure-reducing pad 2 is 4 mm, 4.5 mm, or 5 mm.
[0037] In this embodiment, at least one through hole 4 is also included. The through hole 4 passes through the adhesive tape body 1, the pressure relief pad 2 and the receiving groove 3 in sequence. It is used for ventilation, which can improve the comfort during use. The through hole 4 can also be used to replenish conductive medium, which can reduce the contact resistance of the electrode, protect the electrode from oxidation, and fill the contact surface between the electrode and the skin, so that the electrode can better collect brain signals.
[0038] In this embodiment, the receiving groove 3 is racket-shaped, including a groove head 301 and a groove tail 302. The groove head 301 is coaxial with the through hole 4, and the two ends of the groove tail 302 are respectively connected to the groove head 301 and the notch 6. Specifically, the groove head 301 is circular to restrict the degree of freedom of the electrode head plate, and the groove tail 302 is elongated to restrict the degree of freedom of the electrode handle.
[0039] Optionally, the diameter of the groove head 301 is 1 to 1.4 cm, for example, the diameter of the groove head 301 is 1 cm, 1.2 cm or 1.4 cm.
[0040] In this embodiment, a release paper 5 is also included. The release paper 5 overlaps and is bonded to the adhesive surface of the adhesive tape 1, and the area of the release paper 5 is larger than the area of the adhesive tape 1. The pressure relief pad 2 and the receiving groove 3 are both located between the release paper 5 and the adhesive tape 1, which can effectively prevent the adhesive surface of the adhesive tape 1 from being contaminated before use.
[0041] In this embodiment, the areas of the adhesive tape body 1, the pressure relief pad 2, and the receiving groove 3 are successively reduced in size, so that the adhesive tape body 1 has enough area to adhere to the skin.
[0042] In this embodiment, the pressure relief pad 2 and the receiving groove 3 are located at the center of the adhesive tape body 1. When in use, the adhesive tape body 1 is bonded to the skin through the four sides, resulting in strong stability after bonding.
[0043] In this embodiment, the bottom surface of the receiving groove 3 is provided with an adhesive layer 7 for sticking the electrode, so that the electrode can be pasted and fixed in the receiving groove 3 during use.
[0044] In this embodiment, the side of the pressure-reducing pad 2 away from the adhesive tape body 1 is provided with an adhesive layer 7, which is used to stick to the skin during use and can further improve the fixation effect.
[0045] Preferably, the adhesive layer 7 on the side of the pressure-reducing pad 2 away from the adhesive tape body 1 has a lower adhesive strength than the connection strength between the pressure-reducing pad 2 and the adhesive tape body 1, so that when the adhesive tape body 1 needs to be removed after use, the pressure-reducing pad 2 can be prevented from detaching from the adhesive tape body 1 and remaining on the scalp.
[0046] In this embodiment, the side of the adhesive tape 1 away from the pressure-reducing pad 2 is provided with a buffer layer, which can further disperse the pressure applied by the elastic net cap or bandage on the patient's scalp and avoid excessive local pressure.
[0047] In this embodiment, the adhesive tape body 1 is a non-woven adhesive tape, and the pressure relief pad 2 and the buffer layer are both foam.
[0048] In this embodiment, the release paper is first removed to expose the adhesive side and adhesive layer 7 of the receiving groove 3 and the adhesive tape 1. Then, conductive paste is applied to the side of the electrode that contacts the human skin. Next, the electrode is placed into the receiving groove 3, and the adhesive layer 7 on the bottom surface of the receiving groove 3 adheres to the side of the electrode away from the human skin, so that the electrode is pasted and fixed in the receiving groove 3 with the side of the electrode that contacts the human skin facing away from the adhesive tape 1. Finally, the adhesive side and adhesive layer 7 of the adhesive tape 1 are bonded to the scalp, thereby fixing the electrode to the scalp with the side of the electrode coated with conductive paste in contact with the human skin. The wire connecting the electrode is then passed through the notch 6 out of the receiving groove 3 and connected to the electroencephalogram (EEG) machine, so that the electrode can collect and record electrical signals. During long-term recording, it can effectively avoid pressure injury to the scalp of the subject, especially infants and young children. After recording, the adhesive tape 1 can be moistened with a spray bottle filled with clean water. After the adhesive tape 1 loses its stickiness, it is peeled off and the electrode is removed.
[0049] Example 2
[0050] The difference between this embodiment and Embodiment 1 is that:
[0051] Please refer to Figure 4 and Figure 5In this embodiment, the receiving groove 3 is circular and coaxial with the through hole 4, which is used to restrict the degree of freedom of the electrode head plate part, thereby reducing the occurrence of displacement.
[0052] This embodiment has a simple structure and can effectively reduce production costs.
[0053] Optionally, the diameter of the receiving groove 3 is 1 to 1.4 cm, for example, the diameter of the receiving groove 3 is 1 cm, 1.2 cm or 1.4 cm.
