An electroencephalogram monitoring device for craniocerebral trauma with skull defect bone window

Technical Field

The present application belongs to the technical field of electroencephalograms, and in particular, relates to an electroencephalogram monitoring device for a bone window of a skull defect caused by craniocerebral trauma.

Background Art

The electroencephalogram (EEG) is a graph obtained by amplifying and recording the spontaneous biopotential of the brain from the scalp using sophisticated electronic instruments. It is the spontaneous and rhythmic electrical activities of groups of brain cells recorded by electrodes. The electroencephalogram (EEG) is divided into conventional EEG, dynamic EEG monitoring, and video EEG monitoring. The EEG is also used in the detection of skull conditions caused by craniocerebral trauma.

At present, when the existing EEG detection device is used, the sensor is generally glued to the scalp, which is not only inconvenient but also easy to loosen. Therefore, patients will feel a certain degree of nervousness during the test and dare not make too many movements for fear that the sensor will loosen. Medical staff also need to observe whether the sensor falls off at all times.

Therefore, we propose an EEG monitoring device for the bone window of skull defect in craniocerebral trauma to solve the above problems.

Utility Model Content

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

1-4, an EEG monitoring device for a bone window in a skull defect caused by craniocerebral trauma comprises a circular cap 1, the outer surface of the circular cap 1 is provided with five sliding grooves 19, the interior of each sliding groove 19 is slidably connected with five fixing frames 2, the bottom surface of each fixing frame 2 is fixedly connected with a micromagnetic sensor 9, the upper surface of each micromagnetic sensor 9 is fixedly connected with a wire 11, and the upper surface of each fixing frame 2 is provided with a circular hole 14. By providing the micromagnetic sensor 9 and the wire 11, the patient's head can be detected, which has a good auxiliary effect.

Two first limit plates 10 are fixedly connected to the inner bottom wall of each fixing frame 2, and two fixing straps 3 are arranged under the round cap 1. The upper surface of each fixing strap 3 is fixedly connected to the bottom surface of the round cap 1. By providing the fixing strap 3, the round cap 1 can be fixed on the patient's head by using the fixing strap 3, which has a better auxiliary effect.

The inner wall of each fixing frame 2 is threadedly connected to two threaded shafts 7, and the top of each threaded shaft 7 is fixedly connected to a rotating plate 6. A second limiting plate 8 is arranged inside each fixing frame 2. The right side surface of one fixing belt 3 is fixedly connected to a clamping block 4, and the left side surface of the other fixing belt 3 is fixedly connected to a slot block 5. The outer surface of the clamping block 4 is clamped with the inside of the slot block 5. By providing the clamping block 4 and the slot block 5, the two fixing belts 3 can be connected together by clamping the clamping block 4 to the inside of the slot block 5, thereby ensuring that the round cap 1 is more stable.

The inner wall of each second limit plate 8 is fixedly connected to the first bearing 13, the inner ring of each first bearing 13 is fixedly connected to the first rotating shaft 12, the inner wall of the slot block 5 is fixedly connected to the second bearing 18, and the inner ring of the second bearing 18 is fixedly connected to the second rotating shaft 17. By providing the second bearing 18 and the second rotating shaft 17, the second rotating shaft 17 can rotate inside the second bearing 18, so that the rotation of the second rotating shaft 17 is more stable.

The top end of each first rotating shaft 12 is fixedly connected to the bottom end of the threaded shaft 7, the end of the second rotating shaft 17 away from the clamping block 4 is fixedly connected to the limiting rod 16, the front of the clamping block 4 is fixedly connected to the limiting block 15, the inside of the limiting block 15 is clamped with the outer surface of the limiting rod 16, and by setting the limiting rod 16 and the limiting block 15, the fixing belt 3 can be fixed by the clamping relationship between the limiting block 15 and the limiting rod 16.

The working principle of the utility model is as follows: when in use, the micromagnetic sensor 9 can be first connected to the power supply. When the power supply is connected, the device can be used normally. Before using the device, the position of the fixing frame 2 can be adjusted according to the different sizes of the user's head. When adjusting the position of the fixing frame 2, it is necessary to apply a rotating force to the rotating plate 6. When the rotating plate 6 rotates, it will drive the threaded shaft 7 fixed on the bottom surface to rotate. In conjunction with the threaded connection relationship between the threaded shaft 7 and the fixing frame 2, the second limiting plate 8 can be pulled to move upward, thereby making the second limiting plate 8 and the first limiting plate 10 move away, and then each micromagnetic sensor 9 can be moved to a suitable position. When you want to adjust each When fixing the fixing frame 2, it is only necessary to drive the rotating plate 6 to rotate in the reverse direction, and also utilize the threaded connection relationship between the threaded shaft 7 and the fixing frame 2 to push the second limit plate 8 to move downward, and fix it on the circular cap 1 through the second limit plate 8 and the first limit plate 10. Since the first rotating shaft 12 is fixed to the bottom end of the threaded shaft 7, and the first rotating shaft 12 is inside the first bearing 13, and the outer ring of the first bearing 13 is fixed to the inner wall of the second limit plate 8, the second limit plate 8 will not rotate due to the rotation of the threaded shaft 7, thereby effectively avoiding the problem that the micromagnetic sensor 9 is easily loosened due to adhesion to the head when the device is in use, which causes certain inconveniences.
