In addition, EEG sensors can help anesthesiologists adjust the dosage of anesthetic drugs to achieve the desired anesthetic effect.

[0003] The disposable EEG sensor is directly attached to the human head. The disposable EEG sensor is equipped with a connecting wire, and the sensor body is connected to the EEG monitoring and diagnostic equipment through the connecting wire. However, during the use of the disposable EEG sensor, there is a problem that the connecting wire may be twisted or pulled by external force and disconnected from the EEG sensor, affecting its use.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a brain electrode fixing device, comprising a sensor body and a connecting wire adapted to the sensor body, the sensor body being provided with a connecting male head at one end of the connecting wire facing the sensor body, the connecting female head being provided with a connecting female head adapted to the connecting male head at one end of the connecting wire facing the sensor body, the connecting male head and the connecting female head being pluggable connected, the connecting wire being provided with a first anti-detachment component that connects the sensor body and the connecting wire and reduces the possibility of disconnection between the connecting male head and the connecting female head.

[0008] Through the above technical solution, the sensor body is adhered to the forehead of the patient's head, and the sensor body and the connecting wire are connected through the plug-in connection of the male connecting head and the female connecting head. The first anti-detachment component improves the stability of the connection between the male connecting head and the female connecting head, thereby improving the stability of the connection between the connecting wire and the sensor body, and reducing the possibility of the male connecting head and the female connecting head being disconnected due to twisting or pulling of the connecting wire, thereby affecting the operation of the sensor body.

[0009] Preferably, the first anti-slip component includes a sleeve block nested in the circumferential outer wall of the connecting line and integrated with the connecting line, a connecting rope is fixedly connected to the sleeve block, and the end of the connecting rope away from the sleeve block is fixedly connected to a U-shaped clamp mounted on the outside of the sensor body, and two stop blocks are integrated outside the sensor body, respectively located on both sides of the U-shaped clamp, and the size of the stop block is larger than the size of the U-shaped clamp.

[0010] Through the above technical solution, the sleeve block and the connecting wire are integrated into a structure. When the male connector and the female connector are plugged in and connected, the U-shaped clip is nested outside the sensor body and is located between the two blocks. When the connecting wire is twisted or pulled, the two baffles cooperate to block the U-shaped clip and it will not separate from the sensor body, thereby reducing the possibility of the female connector being disconnected from the male connector as the connecting wire is twisted or pulled.

[0011] Preferably, a threaded groove is provided on the outer side wall of the U-shaped clamp, the long side dimension of the U-shaped clamp is larger than the width of the sensor body, a top plate is provided on the outer shell of the U-shaped clamp, a cylindrical hole adapted to the U-shaped clamp is provided on the top plate, top plates are passed through the cylindrical holes at both ends of the U-shaped clamp, and a nut is provided on the part of the U-shaped clamp passing through the top plate that is threadedly connected to the U-shaped clamp.

[0012] Through the above technical solution, when the U-shaped clamp is nested outside the sensor body, in order to ensure that the male connector and the female connector will not be disconnected, the top plate is sleeved on the outside of the U-shaped clamp through the cylindrical hole, and the top plate contacts the outer wall of the sensor body. Then, the nuts are sleeved on the outside of both ends of the U-shaped clamp, and the nuts are threadedly connected to the U-shaped clamp to facilitate fixing the U-shaped clamp, top plate and nut.

[0013] Preferably, the connecting line is provided with a second anti-slip component for reducing the angle of connection between the male connector and the female connector.

[0014] Through the above technical solution, power is provided by the second anti-detachment component, which further reduces the possibility of the male connector and the female connector being disconnected due to twisting or pulling of the connecting line, thereby improving the stability and safety of the device connection.

When the sensor body and the connecting line are connected through the connecting male head and the connecting female head, the two first support plates and the second support plates on the connecting line are respectively inserted into the grooves on both sides of the strip frame. The strip frame reduces the possibility of the connecting line being pulled and causing the connecting female head and the connecting male head to be disconnected, and does not affect the slight twisting of the connecting line.

[0017] Preferably, the second support plate is provided with a third anti-slip component to reduce the possibility of large-angle twisting of the connecting line.

[0018] Through the above technical solution, by providing the third anti-detachment component, the stability of the connection between the connecting line and the sensor body is further improved.

[0020] Through the above technical solution, the first support plate and the second support plate are respectively located on both sides of the strip frame on the side of the operating bed, and the rotating plate and the connecting rod are located below the strip frame. The torsion of the connecting line will drive the second support plate coaxially fixed with the connecting line to rotate, and the rotation of the second support plate will drive the connecting rod and the rotating plate eccentrically fixed to the second support plate to rotate. Since the rotating plate is located below the strip frame, the rotating plate is stuck by the strip frame when it rotates to conflict with the strip frame, so as to limit the torsion angle of the connecting line.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1-3 As shown, the utility model provides a technical solution: a brain electrode fixing device, comprising a sensor body 1 and a connecting wire 2 adapted to the sensor body 1, the sensor body 1 is provided with a connecting male head 3 at one end facing the connecting wire 2, and the connecting wire 2 is provided with a connecting female head 4 adapted to the connecting male head 3 at one end facing the sensor body 1, the connecting male head 3 and the connecting female head 4 are plug-in connected, and a first anti-detachment component is provided on the connecting wire 2 to connect the sensor body 1 and the connecting wire 2 and reduce the possibility of disconnection between the connecting male head 3 and the connecting female head 4, the sensor body 1 is pasted on the forehead of the patient's head, the sensor body 1 and the connecting wire 2 are connected by plug-in connection with the connecting male head 3 and the connecting female head 4, and the first anti-detachment component improves the stability of the connection between the connecting male head 3 and the connecting female head 4, thereby improving the stability of the connection between the connecting wire 2 and the sensor body 1, and reducing the possibility of disconnection between the connecting male head 3 and the connecting female head 4 due to twisting or pulling of the connecting wire 2, thereby affecting the operation of the sensor body 1.

[0031] like Figure 1 and Figure 2 The first anti-slip component includes a sleeve block 5 nested in the circumferential outer wall of the connecting line 2 and integrated with the connecting line 2. A connecting rope 6 is fixedly connected to the sleeve block 5. The end of the connecting rope 6 away from the sleeve block 5 is fixedly connected to a U-shaped clip 7 sleeved on the outside of the sensor body 1. Two stoppers 8 are integrated outside the sensor body 1 and are located on both sides of the U-shaped clip 7. The size of the stopper 8 is larger than that of the U-shaped clip 7.

[0032] like Figure 1 and Figure 2 The sleeve block 5 is an integrated structure with the connecting wire 2. When the connecting male connector 3 and the connecting female connector 4 are plugged in and connected, the U-shaped clip 7 is nested outside the sensor body 1 and is located between the two stoppers 8. When the connecting wire 2 is twisted or pulled, the U-shaped clip 7 is blocked by the baffles through the cooperation of the two baffles and will not be separated from the sensor body 1, thereby reducing the possibility of the connecting female connector 4 being disconnected from the connecting male connector 3 as the connecting wire 2 is twisted or pulled.

[0033] As shown in the figure, a thread groove is provided on the outer wall of the U-shaped clamp 7, the long side of the U-shaped clamp 7 is larger than the width of the sensor body 1, a top plate 9 is provided on the outer sleeve of the U-shaped clamp 7, a cylindrical hole 10 adapted to the U-shaped clamp 7 is provided on the top plate 9, both ends of the U-shaped clamp 7 are penetrated by the top plate 9 through the cylindrical holes 10, and a nut 11 threadedly connected to the U-shaped clamp 7 is provided on the part of the U-shaped clamp 7 passing through the top plate 9.

[0034] like Figure 1 and Figure 2 When the U-shaped clamp 7 is nested outside the sensor body 1, in order to ensure that the male connector 3 and the female connector 4 will not be disconnected, the top plate 9 is sleeved outside the U-shaped clamp 7 through the cylindrical hole 10. The top plate 9 contacts the outer wall of the sensor body 1, and then the nuts 11 are sleeved on the outside of both ends of the U-shaped clamp 7. The nuts 11 are threadedly connected to the U-shaped clamp 7 to fix the U-shaped clamp 7, the top plate 9 and the nuts 11.

[0035] like Figure 1 A second anti-detachment component is provided on the connecting line 2 to reduce the connection between the end angles of the connecting male head 3 and the connecting female head 4. The second anti-detachment component provides power to further reduce the possibility of the connecting line 2 being disconnected due to twisting or pulling, thereby improving the stability and safety of the device connection.

[0036] like Figure 1 and Figure 3 The second anti-slip assembly includes a first support plate 12 and a second support plate 13 nested outside the connecting line 2 and fixedly connected to the connecting line 2. The first support plate 12 and the second support plate 13 are respectively nested with an annular plate 14 coaxially arranged with the first support plate 12 and the second support plate 13 and rotatably connected.

[0037] like Figure 1 and Figure 3 , both sides of the existing medical bed or operating bed are provided with a strip frame. When the sensor body 1 and the connecting line 2 are connected through the connecting male connector 3 and the connecting female connector 4, the two first support plates 12 and the second support plates 13 on the connecting line 2 are respectively inserted into the grooves on both sides of the strip frame. The strip frame reduces the possibility of the connecting line 2 being pulled and causing the connecting female connector 4 and the connecting male connector 3 to be disconnected, and does not affect the slight twisting of the connecting line 2.

[0038] like Figure 1 and Figure 3 The second support plate 13 is provided with a third anti-slip component to reduce the possibility of large-angle twisting of the connecting line 2. By providing the third anti-slip component, the stability of the connection between the connecting line 2 and the sensor body 1 is further improved.

[0039] like Figure 1 and Figure 3 The third anti-slip assembly includes a connecting rod 15 fixed on the second support plate 13 and arranged horizontally. The connecting rod 15 is eccentrically arranged with the second support plate 13 and is located below the connecting line 2. A rotating plate 16 is integrated at one end of the connecting rod 15 away from the second support plate 13.

[0040] like Figure 1 and Figure 3 The first support plate 12 and the second support plate 13 are respectively located on both sides of the strip frame on the side of the operating bed, and the rotating plate 16 and the connecting rod 15 are located below the strip frame. The torsion of the connecting line 2 will drive the second support plate 13 coaxially fixed with the connecting line 2 to rotate, and the rotation of the second support plate 13 will drive the connecting rod 15 and the rotating plate 16 eccentrically fixed to the second support plate 13 to rotate. Since the rotating plate 16 is located below the strip frame, the rotating plate 16 is stuck by the strip frame when it rotates to conflict with the strip frame, so as to limit the torsion angle of the connecting line 2.

[0041] like Figure 1 and Figure 3 The size of the rotating plate 16 is larger than the gap between the strip frame structure and the bed body. When the rotating plate 16 rotates, it will contact the lower surface of the bed body and will not rotate out of the gap between the bed body and the strip frame structure.

[0042] When in use, the power is turned on, the switch is turned on, and the medical staff takes out the sensor body 1 and sticks the sensor body 1 to the appropriate position of the patient's face, and then plugs the male connector 3 of the sensor body 1 into the female connector 4 of the connecting line 2. This is an existing device and existing technology, so it will not be described in detail here;

[0043] Before the male connector 3 and the female connector 4 are plugged in and connected, the connecting wire 2 passes through the baffle frame on the side of the operating bed. The bottom of the traditional baffle frame is a strip frame structure. The connecting wire 2 is overlapped and placed on the upper surface of the strip frame structure. The first support plate 12 and the second support plate 13 are respectively placed on both sides of the strip frame structure and are located in the gap between the strip frame structure and the bed body. The annular plate 14 is in contact with the strip frame structure. When the connecting wire 2 is twisted or pulled, the first support plate 12 and the second support plate 13 cooperate to limit the position of the connecting wire 2, thereby reducing the possibility of disconnection between the male connector 3 and the female connector 4;

[0044] The rotating plate 16 is located under the bed. When the connecting line 2 is twisted, the rotation of the connecting line 2 drives the first support plate 12 and the second support plate 13 fixed to the connecting line 2 to rotate. The rotation of the second support plate 13 drives the connecting rod 15 fixed to the second support plate 13 to rotate. The rotation of the connecting rod 15 drives the rotating plate 16 fixed to the connecting rod 15 to rotate. The rotating plate 16 rotates until it contacts the lower surface of the bed. At this time, the connecting line 2 cannot continue to twist. Therefore, the twisting angle of the connecting line 2 is limited to reduce the possibility that the twisting angle of the connecting line 2 is too large, which may cause the male connector 3 and the female connector 4 to disconnect or the connecting rope 6 to break.

[0045] Then, grab the U-shaped clamp 7 so that the U-shaped clamp 7 is nested outside the sensor body 1 and located between the two baffles. Then, put the top plate 9 on the outside of the U-shaped clamp 7 through the cylindrical hole 10. Then put the nut 11 on the outside of the U-shaped clamp 7 and manually rotate the nut 11. The nut 11 is threadedly connected to the U-shaped clamp 7. The nut 11 is manually rotated. The nut 11 moves during the rotation, pushing the top plate 9 to move until it contacts the outer wall of the sensor body 1. The top plate 9 is also located between the two baffles. When the connecting line 2 is twisted or pulled, the U-shaped clamp 7 is contacted by the baffle, and the connecting rope 6 connects the U-shaped clamp 7 and the sleeve block 5. The U-shaped clamp 7 is not disconnected from the sensor body 1, and the connecting male head 3 is not disconnected from the connecting female head 4. This is the use process of the brain electrode fixing device. At the same time, the contents not described in detail in this manual belong to the existing technology known to professional and technical personnel in this field.
