[0030] Combine the following Figure 1-Figure 5 The utility model describes a brain function acquisition device for stroke patients.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a brain function acquisition device for stroke patients includes a wearable component 100, an acquisition unit 200, and an oral protection component 300.

[0032] The wearing piece 100 includes a forehead shell 110 and a connecting strap 120, and is used to be worn on the patient's head; optionally, Velcro is provided on the inner lining of both sides of the forehead shell 110, and the outer layer of the Velcro is adhered with a sponge lining to improve wearing comfort and reduce the pressure of the device on the patient's head.

[0033] Specifically, the forehead shell 110 is an open ring, and the connecting strap 120 is fixedly connected to the two ends of the opening of the forehead shell 110. An adjustment hole is provided on one side of the connecting strap 120, and a headband adjustment buckle is provided on the other side of the connecting strap 120. When the two connecting straps 120 are connected, the headband adjustment buckle can be engaged with the adjustment hole to achieve coordination with the patient's head circumference, thereby making the forehead shell 110 and the collection unit 200 close to the patient's head.

[0034] The acquisition unit 200 is detachably mounted on the forehead housing 110 at a position opposite to the patient's forehead, and is used to acquire the patient's electroencephalogram signal.

[0035] The oral protection assembly 300 includes a mouth expander 310, a connecting tube 320 and a medical air pump 330. The surface of the mouth expander 310 has an air bag 340. The medical air pump 330 is connected to the air bag 340 through the connecting tube 320. Optionally, the mouth expander 310 has a mounting hole 311, and the mounting hole 311 is used to fix the saliva suction tube on the mouth expander 310.

[0036] Specifically, during the examination of a stroke patient, the stroke injury may cause the tongue muscles and oral masticatory muscles to fail to cooperate, which may easily lead to the tongue being bitten. Therefore, during the patient examination, the oral protection component 300 is placed in the patient's mouth and isolates the patient's teeth and tongue to protect the inside of the patient's mouth. Figure 3 .

[0037] The brain function acquisition device for stroke patients of this embodiment has a connecting belt 120 formed into a ring-shaped headband through an adjustment buckle to wear the forehead shell 110 on the patient's head, so that the acquisition unit 200 is in close contact with the patient's head, and the sponge linings on both sides can reduce the pressure of the device on the patient's head. The mouth expander 310 is placed in the patient's mouth, and the air bag 340 is inflated by the medical air pump 330 to fill the patient's entire mouth. The mouth expander 310 is prevented from falling off, and the risk of biting the tongue after a stroke damages the nerves that control the tongue muscles and oral masticatory muscles is effectively avoided; at the same time, the saliva suction tube can absorb excess saliva in the mouth to reduce the probability of choking.

[0038] After the patient's brain electrical signals are collected, they are transmitted to the connected external receiving device through wires for amplification, filtering and other processing before display. It should be noted that the model of the medical air pump 330 is TNY31-D2-G, which is connected to the external receiving device through existing sensors. The adopted EEG processing technology and the medical air pump 330 are both conventional processing instruments or equipment in the prior art, and their working principles are not elaborated in detail here.

[0039] like Figure 3 As shown, in one embodiment, an elastic clip 312 is fixedly installed on the inner wall of the mouth expander 310, and absorbent cotton is clamped between the elastic clip 312 and the inner wall of the mouth expander 310. When the patient wears the mouth expander 310, part of the saliva choked out of the mouth is absorbed by the absorbent cotton, reducing the risk of infection.

[0040] like Figure 4 As shown, in one embodiment, the collection unit 200 includes an adjustment portion 210, an elastic portion 220 and an electrode sheet 230, the adjustment portion 210 is used to make the electrode sheet 230 correspond to the collection point on the patient's forehead, and the elastic portion 220 is used to adjust the angle between the electrode sheet 230 and the patient's forehead and make them stick tightly.

[0041] See also Figure 5 As an option, the adjustment part 210 includes a moving plate 211, a pressure rod 212 and a pressure cap 213. The forehead housing 110 has a first slide groove 101 adapted to the moving plate 211 inside, the pressure rod 212 is slidably mounted on the moving plate 211, and one end of the pressure rod 212 passing through the forehead housing 110 is fixedly connected to the pressure cap 213, the forehead housing 110 has a second slide groove 102 for the pressure rod 212 to move, the pressure rod 212 has a boss 214, and the boss 214 and the inner top surface of the forehead housing 110 are fixedly mounted with a brake pad 215 that can contact each other. The pressure rod 212 is sleeved with a first spring 216, and the two ends of the first spring 216 are respectively in contact with the forehead housing 110 and the pressure cap 213.

[0042] In order to make the electrode sheet 230 fit the patient's forehead, the operator can press the pressure cap 213 after the patient wears the forehead housing 110, the pressure rod 212 slides down under the force, and the first spring 216 is compressed. At this time, the brake pad 215 on the boss 214 is separated from the brake pad 215 on the top surface of the forehead housing 110, and the movable plate 211 can move freely in the forehead housing 110 and drive the electrode sheet 230 to move, so as to move to a suitable position. After releasing the pressure cap 213, the pressure rod 212 and the boss 214 are reset under the force of the first spring 216, and the brake pads 215 on both sides are pressed together again to fix the position.

[0043] See also Figure 5 Optionally, the elastic part 220 includes a set 221, a slide bar 222 and a second spring 223, wherein the set 221 is used to slide and install the electrode sheet 230 on the slide bar 222, the slide bar 222 is fixedly connected to the moving plate 211, the second spring 223 is sleeved on the slide bar 222, and the two ends of the second spring 223 are respectively in contact with the set 221 and the moving plate 211. Optionally, the set 221 includes a first shaft 201 and a second shaft 202, one end of the first shaft 201 is fixedly connected to the electrode sheet 230, the other end of the first shaft 201 has a ball 203, one end of the second shaft 202 is slidably installed on the slide bar 222, the other end of the second shaft 202 has a ball seat 204 adapted to the ball 203, and the ball 203 is rotatably connected in the ball seat 204.

[0044] After the electrode sheet 230 is adjusted to the position and in contact with the patient's forehead, the electrode sheet 230 finds a suitable contact angle between the electrode sheet 230 and the patient's forehead through the rotation of the ball 203 in the ball seat 204, thereby reducing the impedance and ensuring that each electrode sheet 230 is subjected to uniform force. At the same time, the electrode sheet 230 applies a pressure to the second spring 223 on the second shaft 202. The pre-tightening force generated by the second spring 223 makes the electrode sheet 230 fit more closely to the patient's forehead, thereby ultimately achieving more accurate EEG signal collection.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
