Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a fixing pressing sheet for a brain function monitoring electrode sheet. Background Art

[0002] The electrical activity of brain cells is the basic form of brain function. Newborns of different gestational ages have different characteristics, and the brain electrical activity will change correspondingly under the action of various high-risk factors. Therefore, electroencephalogram has long been used as an important method for evaluating brain maturity and brain damage in clinical work. A brain function monitor is an instrument that amplifies the weak spontaneous bioelectricity of the brain through the scalp to form waveforms, and reflects the brain through a trend graph after quantization and compression. It is mainly reflected through electroencephalogram and is one of the important means for evaluating brain function at present.

[0003] Clinically, when using a brain function monitor to monitor the brain function of newborns, it is necessary to closely attach each electrode sheet to the corresponding position on the scalp according to the electrode sites to obtain brain wave information. The electrode sheet needs to be fixed to the scalp of the child to stably receive the brain waves of the patient. Clinically, it is generally fixed to the scalp of the child by tape sticking or fixed to the scalp of the child by pressing with an elastic net cap. However, the above two methods have the following disadvantages: 1) The method of tape sticking is easy to adhere to the hair, resulting in pulling the hair when removing the electrode sheet, increasing the pain of the child and taking a long time; at the same time, a certain pressure needs to be applied to the scalp of the child when tape sticking, which is easy to cause scalp compression injury to the child; 2) The elasticity of the elastic net cap is insufficient, and it is impossible to firmly press the electrode sheet against the head of the child, resulting in easy displacement and falling off of the electrode sheet, affecting the monitoring results; at the same time, due to the different head circumferences of children, the elastic net cap is often difficult to be suitable for all children, thus affecting the fixing effect of the electrode sheet.

[0004] Therefore, there is a need to develop a fixing device that can stably fix the electrode sheet without causing harm to the scalp of the child. Content of the Utility Model

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the technical defects that the method of tape sticking in the prior art is easy to adhere to the hair and is easy to cause compression to the scalp of the child, thus easily hurting the scalp of the child; while using the elastic net cap is easy to cause easy displacement and falling off of the electrode sheet due to insufficient elasticity of the elastic net cap, affecting the monitoring results, so as to provide a fixing pressing sheet for a brain function monitoring electrode sheet that can stably fix the electrode sheet without causing harm to the scalp of the child.

[0006] To this end, the utility model provides a fixing pressing sheet for a brain function monitoring electrode sheet, comprising:

[0007] The main body, made of flexible material, includes a first fixing part and a second fixing part arranged around the first fixing part; the front surface of the first fixing part is suitable for pressing on the electrode sheet, and the front surface of the second fixing part is suitable for pressing on the skin;

[0008] The first anti-slip structure is arranged on the front surface of the first fixing part;

[0009] The second anti-slip structure is arranged on the front surface of the second fixing part;

[0010] The limiting structure is arranged on the back surface of the main body and is used for mutual limitation with the elastic mesh cap.

[0011] Furthermore, the first anti-slip structure is a number of anti-slip bumps formed on the front surface of the first fixing part.

[0012] Furthermore, the second anti-slip structure is a number of anti-slip bumps formed on the front surface of the second fixing part.

[0013] Furthermore, the limiting structure is a limiting post formed on the back surface of the main body.

[0014] Furthermore, it further includes:

[0015] The wire passing hole passes through the limiting post and the main body in sequence;

[0016] The wire passing gap extends from the edge of the main body 1 towards the wire passing hole and is communicated with the wire passing hole.

[0017] Furthermore, it further includes: ventilation holes, which are arranged through the main body.

[0018] Furthermore, the front end face of the first fixing part protrudes from the front end face of the second fixing part, and the height of the part where the front end face of the first fixing part protrudes from the front end face of the second fixing part is less than or equal to the thickness of the electrode sheet.

[0019] Furthermore, the second fixing part is two strip-shaped structures symmetrically arranged on both sides of the first fixing part.

[0020] Furthermore, the edges of the free ends of the two strip-shaped structures are arc-shaped.

[0021] Furthermore, the fixing pressing piece is an integrally formed structure.

[0022] The technical solution provided by the present utility model has the following advantages:

[0033] The following will detail this application with reference to the accompanying drawings and in conjunction with embodiments.

[0034] This embodiment provides a fixing pressing piece for a brain function monitoring electrode sheet, as Figures 1-3As shown, it includes a body 1, a first anti-slip structure 2, a second anti-slip structure 3 and a limiting structure 4; wherein, the body 1 is made of a flexible material and includes a first fixing part 11 and a second fixing part 12 arranged around the first fixing part 11; the front surface of the first fixing part 11 is suitable for pressing on the electrode sheet, and the front surface of the second fixing part 12 is suitable for pressing on the skin; the first anti-slip structure 2 is arranged on the front surface of the first fixing part 11; the second anti-slip structure 3 is arranged on the front surface of the second fixing part 12; the limiting structure 4 is arranged on the back surface of the body 1 and is used for mutual limitation with the elastic mesh cap.

[0035] In this embodiment, the body 1 is made of a flexible material, specifically, it can be made of silicone, plastic or rubber. The front surface of the first fixing part 11 is suitable for pressing on the electrode sheet, and the first anti-slip structure 2 can increase the friction between the first fixing part 11 and the electrode sheet. The front surface of the second fixing part 12 is suitable for pressing on the skin, and the second anti-slip structure 3 can increase the friction between the second fixing part 12 and the skin. When in use, first put the elastic mesh cap on the head of the child to preliminarily fix the electrode sheet; then place the fixing tablet of this embodiment on the electrode sheet to be fixed. Specifically, first lift the elastic mesh cap at the corresponding position of the electrode sheet, place the fixing tablet between the elastic mesh cap and the tablet. Under the action of the elastic force of the mesh cap, the first anti-slip structure 2 on the front surface of the first fixing part 11 frictionaly fits with the electrode sheet, and the second anti-slip structure 3 on the front surface of the second fixing part 12 frictionaly fits with the skin of the child. In this way, the electrode sheet will be fixedly attached to the head of the child.

[0036] For the fixing tablet of the brain function monitoring electrode sheet in this embodiment, the first anti-slip structure 2 is a number of anti-slip bumps formed on the front surface of the first fixing part 11.

[0037] In this embodiment, the anti-slip bumps can increase the friction between the front surface of the first fixing part 11 and the electrode sheet.

[0038] For the fixing tablet of the brain function monitoring electrode sheet in this embodiment, further, the second anti-slip structure 3 is a number of anti-slip bumps formed on the front surface of the second fixing part 12.

[0039] In this embodiment, the anti-slip bumps can increase the friction between the front surface of the second fixing part 12 and the skin of the child.

[0040] For the fixing tablet of the brain function monitoring electrode sheet in this embodiment, the limiting structure 4 is a limiting post formed on the back surface of the body 1.

[0041] In this embodiment, the limiting post can pass through the holes of the elastic mesh cap, so as to mutually limit with the elastic mesh cap.

[0042] The fixing pressing piece for the brain function monitoring electrode patch in this embodiment further includes a wire passing hole 100 and a wire passing slit 200. The wire passing hole 100 sequentially penetrates through the limiting column and the body 1. The wire passing slit 200 extends from the edge of the body 1 towards the wire passing hole 100 and communicates with the wire passing hole 100.

[0043] The electrode patch is generally connected to the brain function monitor through an electrode wire. When the fixing pressing piece presses on the electrode wire, if the electrode wire is pulled by force, it may lift the fixing pressing piece. In this embodiment, both the wire passing hole 100 and the wire passing slit 200 can be used for the electrode wire connected to the electrode patch to pass through, so as to prevent the fixing pressing piece from being lifted when the electrode wire is pulled.

[0044] The fixing pressing piece for the brain function monitoring electrode patch in this embodiment further includes a ventilation hole 300, and the ventilation hole 300 is disposed through the body 1.

[0045] In this embodiment, the ventilation hole 300 can ensure the air permeability of the skin of the child at the covered part of the fixing pressing piece, and improve the wearing comfort of the fixing pressing piece in this embodiment.

[0046] For the fixing pressing piece for the brain function monitoring electrode patch in this embodiment, the front end face of the first fixing part 11 protrudes from the front end face of the second fixing part 12, and the height of the part where the front end face of the first fixing part 11 protrudes from the front end face of the second fixing part 12 is less than or equal to the thickness of the electrode patch.

[0047] In this embodiment, the height of the part where the front end face of the first fixing part 11 protrudes from the front end face of the second fixing part 12 is less than or equal to the thickness of the electrode patch, which can ensure good contact between the first fixing part 11 and the electrode patch, while the second fixing part 12 can also achieve good contact with the skin of the child, and can ensure firm adhesion to both the electrode patch and the skin of the child under the pressure of the elastic net cap.

[0048] For the fixing pressing piece for the brain function monitoring electrode patch in this embodiment, further, the second fixing part 12 is two strip-shaped structures symmetrically arranged on both sides of the first fixing part 11.

[0049] In this embodiment, the second fixing part 12 is set as two strip-shaped structures and symmetrically arranged on both sides of the first fixing part 11, so as to greatly reduce the covering area of the fixing pressing piece in this embodiment and avoid the fixing pressing piece in this embodiment touching organs such as the eyes, nose or ears of the child during use, thereby improving the use comfort of the fixing pressing piece in this embodiment.

[0050] For the fixing pressing piece for the brain function monitoring electrode patch in this embodiment, further, the edges of the free ends of the two strip-shaped structures are arc-shaped.

[0051] In this embodiment, the edges of the free ends of the two strip structures are set to be arc-shaped, which can prevent the appearance of sharp angular structures, thereby avoiding stabbing the child's body.

[0052] For the fixing pressing piece of the brain function monitoring electrode patch in this embodiment, further, the fixing pressing piece is an integrally formed structure.

[0053] The using process of the fixing pressing piece of the brain function monitoring electrode patch in this embodiment is as follows:

[0054] First, put the elastic net cap on the child's head to preliminarily fix the electrode patch with the elastic net cap.

[0055] Then lift the elastic net cap at the corresponding position of the electrode patch to be fixed, place the fixing pressing piece between the elastic net cap and the pressing piece, make the first fixing part 11 fit completely with the electrode patch, make the second fixing part 12 fit completely with the child's skin, and at the same time, make the limiting posts pass through the holes of the elastic net cap.

[0056] Adjust the fixing pressing piece to make the electrode wire pass through the wire passing hole 100 or the wire passing gap 200. At the same time, adjust the position of the second fixing part 12 to make it away from the child's eyes, nose or ears and other organs.

[0057] Under the action of the elasticity of the net cap, the anti-slip bumps on the front surface of the first fixing part 11 are frictionally attached to the electrode patch, and the anti-slip bumps on the front surface of the second fixing part 12 are frictionally attached to the child's skin. In this way, the electrode patch will be attached and fixed to the child's head.

[0058] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of this innovative technical solution.
