Description

Technical Field

[0001] The present invention relates to the technical field of epilepsy examination, and in particular to a fixing device for examining children's epilepsy. Background Art

[0002] During the clinical examination of childhood epilepsy, children may experience involuntary convulsions, limb tremors, etc., which may make it difficult for the head and limbs to remain stable. This will not only affect the accuracy of electroencephalogram (EEG) and imaging examinations, but may also cause secondary injuries due to loss of limb control.

[0003] Currently, most commonly used clinical examination and fixation devices are simple in structure, primarily securing the patient's limbs with straps or splints. However, specialized fixation devices for children have significant shortcomings: First, traditional devices have limited height adjustment, making it difficult to adapt to the height differences of children of different ages, which can easily lead to deviations in the head fixation position. Second, head fixation structures are often single-directional, lacking three-dimensional fixation of key areas such as the forehead and temples. This makes it difficult to effectively limit head movement during convulsions, and the rigid contact can cause discomfort. Summary of the Invention

[0004] The purpose of the present invention is to address the problems existing in the background technology and to propose a fixation device for examining epilepsy in children that can fix the head in multiple ranges and prevent the patient's head from moving.

[0022] like Figure 1-5 As shown, the present invention provides a fixing device for examining children's epilepsy, comprising an examination chair 1, a connecting component 2, a fixing component 3, a protective component 4, and a pushing component 5; The connecting assembly 2 is slidably mounted on the examination chair 1 and is detachably connected; the fixing assembly 3 is slidably mounted on the connecting assembly 2; two protective assemblies 4 are provided and are rotatably mounted on the fixing assembly 3; two pushing assemblies 5 are provided and slidably mounted on the fixing assembly 3 for pushing the protective assembly 4 to flip. The examination chair 1 includes a support frame 101, a leg rest 102 mounted on the support frame 101, a seat cushion 104 mounted on the support frame 101, a hand restraint assembly 103 rotatably mounted on the seat cushion 104, and a backrest 105 mounted on the support frame 101. There are two hand restraint assemblies 103, including an armrest 1031 rotatably mounted on the seat cushion 104, a hand rest 1032 mounted on the armrest 1031, and a plurality of restraint straps 1033, all mounted on the hand rest 1032.

[0023] In this embodiment, the leg rest 102, the seat cushion 104 and the backrest 105 are supported by the support frame 101. The patient sits on the seat cushion 104 and leans on the backrest 105. The armrests 1031 are flipped so that the two armrests 1031 move to both sides of the patient. The patient's arms are placed on the hand rests 1032, and the patient's arms are restrained by the restraint belts 1033 to prevent the patient from convulsing during the examination.

[0024] The position of the connecting component 2 is adjusted according to the patient's height so that the patient's head can be located at the connecting component 2, and the patient's head is moved between the splints 301. The two splints 301 are driven toward the patient's head by the bidirectional screw rod 302, so that the splint 301 can drive the protective component 4 and the pushing component 5 to move, so that the pushing component 5 can first contact the patient's head, and push the protective component 4 to flip through the pushing component 5, so that the protective component 4 can be pressed on both sides of the patient's forehead, so that the protective component 4 and the pushing component 5 can fix the patient's head, which is convenient for examination. Example

[0025] like Figure 1-5As shown, the present invention proposes a fixing device for examining epilepsy in children. Compared to the first embodiment, the connecting assembly 2 in this embodiment includes a connecting plate 201 slidably mounted on the backrest 105, a connecting rod 202 mounted on the connecting plate 201, a clamping rod 203 detachably mounted on the connecting rod 202, and an abutting bolt 204 threadedly connected to the clamping rod 203 and abutting the backrest 105. The connecting rod 202 is provided with a clamping groove 2021, and the clamping rod 203 is provided with a limiting groove 2031; the clamping rod 203 is embedded in the clamping groove 2021, and the connecting rod 202 is embedded in the limiting groove 2031. The backrest 105 is provided with a mounting groove, and the connecting rod 202 is slidably mounted in the mounting groove.

[0026] The fixing assembly 3 includes two splints 301 that are slidably arranged on the connecting plate 201, a bidirectional screw rod 302 that is rotatably arranged on the connecting plate 201 and threadedly connected to the splint 301, a guide rail 303 that is arranged on the connecting plate 201 and slidably connected to the splint 301, and a handle 304 that is arranged on the bidirectional screw rod 302.

[0027] The protective assembly 4 includes a rotating arm 402 rotatably mounted on the clamping plate 301, a protective plate 401 mounted on the rotating arm 402, a mounting bracket 403 mounted on the clamping plate 301, and an elastic member 404 having two ends connected to the mounting bracket 403 and the rotating arm 402, respectively. The pushing assembly 5 includes a limiting rod 502 slidably mounted on the clamping plate 301, a push plate 501 mounted on the limiting rod 502, and a push ring 503 mounted on the rotating arm 402 and slidably connected to the push plate 501. The pushing assembly 5 is used to push the protective assembly 4 to flip so that it can press against both sides of the patient's head and squeeze toward the forehead, thereby better fixing the patient's head.

[0028] In this embodiment, the connecting rod 202 is passed through the installation slot, and the clamping rod 203 is then clamped onto the connecting rod 202, so that the clamping slot 2021 cooperates with the limiting slot 2031 to fix the clamping rod 203 to prevent the clamping rod 203 from falling. By rotating the abutment bolt 204, the abutment bolt 204 moves axially, so that the abutment bolt 204 can abut on the backrest 105, so that the connecting plate 201 can be pressed on the backrest 105, and the connecting plate 201 is limited and fixed, so that the connecting plate 201 stops at the current position. When the height of the connecting plate 201 needs to be adjusted, the abutment bolt 204 needs to be loosened so that the connecting plate 201 can move and can be adjusted according to the patient's height, so that the patient's head can be better fixed.

[0029] The patient's head is located between the two splints 301. The handle 304 is rotated, and the handle 304 drives the bidirectional screw rod 302 to rotate. The bidirectional screw rod 302 drives the splints 301 to move, so that the two splints 301 can move toward or away from the patient's head at the same time. When the splint 301 moves toward the patient's head, it can drive the push plate 501 to move, so that the push plate 501 is against both sides of the patient's head. When the push plate 501 moves, it will push the push ring 503 to move. The limit rod 502 is used to limit the push plate 501, and the push ring 503 drives the rotating arm 402 to flip, and the rotating arm 402 drives the protective plate 401 to flip, so that the protective plate 401 can be pressed against the side of the patient's forehead, thereby fixing the patient's head in a semi-enclosed type to prevent the patient's head from moving and affecting the examination.

[0030] When the two splints 301 are separated, the elastic member 404 pushes the rotating arm 402 to reset, thereby resetting the protective plate 401. The rotating arm 402 simultaneously pushes the push plate 501 to move, so that the push plate 501 is reset and restored to its initial state, which can facilitate the patient's head to move away from or enter between the two splints 301.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
