Description

Technical Field

[0001] This utility model relates to the field of neonatal electroencephalography (EEG), specifically a three-dimensional comparative model for neonatal EEG examination. Background Technology

[0002] Electroencephalography (EEG) is a modern diagnostic tool that amplifies and records the brain's weak bioelectrical signals into a graph using an electroencephalogram (EEG) recorder to aid in disease diagnosis. During neonatal ambulatory EEG monitoring, EEG technicians attach the EEG recorder's electrodes to corresponding areas on the newborn's head using an adhesive gel. Currently, electrode application is based on the international 10-20 system, such as... Figure 1 The attached positions shown are part of a standardized system designed to ensure accurate recording of EEG signals. However, workers typically adhere to drawings for assembly, lacking a physical model for reference. Chinese utility model patent application number 202022152537.3 discloses a rapid positioning model for scalp EEG electrodes. This model obtains cranial surface parameters using a thin-slice CT or MRI scan of the head; a 3D-printed cranial surface model is created based on these parameters; the electrode positions are then determined within this model to form a cranial surface positioning model; this model is then attached to the patient's scalp, and the electrode positions are mapped one-to-one to the electrode installation locations, thus completing the rapid positioning of the scalp EEG electrodes.

[0003] The aforementioned utility model achieves rapid and accurate positioning, and allows the same positioning to be repeated during secondary examinations, greatly improving the comparative effect. However, it is a model that is placed on the patient's head, and its design requires obtaining the patient's cranial surface model parameters through thin-slice CT or MRI scans, which is quite cumbersome. Furthermore, it is not a three-dimensional model for staff to refer to. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a three-dimensional comparative model for neonatal electroencephalography (EEG) examination. This model has a three-dimensional structure, sets electrode positions based on the international 10-20 system, and allows for rotational adjustment of the angle, facilitating electrode placement for staff and effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-dimensional comparative model for neonatal electroencephalogram examination, comprising a sphere, wherein a nasal protrusion is fixedly provided on the front side of the sphere, a left ear protrusion is provided on the left side, and a right ear protrusion is provided on the right side, and several circular plates are glued to the upper side of the sphere with these three points as base points, and raised markings are glued to the outer surface of the circular plates.

[0006] The bottom of the sphere has a blind hole embedded upwards, and a malleable bracket is provided below the blind hole. The top of the bracket extends into the blind hole and is glued and fixed, and the bottom of the bracket is connected to an adjustable base.

[0007] As a preferred technical solution, the bracket is a stainless steel serpentine tube.

[0008] As a preferred technical solution, the base includes a base plate, and a ball sleeve with an upper opening is fixedly provided on the upper surface of the base plate. A ball head is rotatably provided in the ball sleeve, and the upper surface of the ball head is fixedly connected to the bottom of the support.

[0009] One side of the ball sleeve is also screwed inward with a limit bolt.

[0010] As a preferred technical solution, suction cups are provided at circumferential intervals along the bottom edge of the base plate.

[0011] As a preferred technical solution, the circular plate is a magnetic plate, with circular magnetic sheets glued to its outer surface.

[0012] As a preferred technical solution, the diameter of the magnetic sheet is the same as the diameter of the magnetic plate.

[0013] Compared with the prior art, this utility model provides a three-dimensional comparative model for neonatal electroencephalogram (EEG) examination, which has the following beneficial effects:

[0014] 1. This utility model has a nose protrusion fixed on the front side of the sphere, a left ear protrusion on the left side, and a right ear protrusion on the right side. Several circular plates are glued to the upper side of the sphere with these three points as base points. The outer surface of the circular plates is glued with raised markings. When in use, the sphere imitates the human head. Based on the three protrusions as base points, the circular plates can simulate the pasting position of the human head electrodes. The markings make it easy for staff to find the correct position.

[0015] 2. This utility model features a blind hole embedded at the bottom of the sphere, with a malleable bracket below the blind hole. The top of the bracket extends into the blind hole and is glued and fixed. The bottom of the bracket is attached to an adjustable base. In use, the bracket can be bent to adjust the position of the top sphere, making it convenient for staff to check the electrode position.

[0016] 3. This utility model includes a base plate with a ball sleeve with an upper opening fixed on the upper surface of the base plate. A ball head is rotatably provided in the ball sleeve. The upper surface of the ball head is fixedly connected to the bottom of the bracket. A limit bolt is also screwed inward on one side of the ball sleeve. When in use, the limit bolt is loosened, and the ball can swing circumferentially to adjust its position, which is convenient for the staff to observe the position of the electrode from multiple angles. Tightening the limit bolt can position the ball head.

[0017] 4. This utility model has suction cups spaced around the circumferential edge of the bottom surface of the base plate. When in use, the suction cups can be used to adhere and fix it to a smooth work surface, which is beneficial to the firmness of use.

[0018] 5. This utility model uses a circular plate as a magnetic plate, with circular magnetic sheets glued to the outer side. The diameter of the magnetic sheets is the same as that of the magnetic plate. When using it, the magnetic sheets can be removed at the beginning. After each electrode is glued to the newborn's head, the magnetic sheet is attached to the same position on the model to avoid confusion. The same diameter makes it easy for the staff to grasp and remove the magnetic sheets. Attached Figure Description

A blind hole (not visible) is embedded at the bottom of the sphere 4, and a malleable support 3 is located below the blind hole. The top of the support 3 extends into the blind hole and is glued and fixed. The bottom of the support 3 is connected to an adjustable-angle base. The support 3 is a stainless steel snake tube.

[0026] The base includes a base plate 1, and a ball sleeve 2 with an upper opening is fixedly provided on the upper surface of the base plate 1. A ball head 21 is rotatably provided in the ball sleeve 2. The upper surface of the ball head 21 is fixedly connected to the bottom of the bracket 3.

[0027] The bottom edge of the base 1 is provided with suction cups 11 spaced around it.

[0028] In use, the sphere 4 mimics the human head, with three protrusions as base points. The circular plate 5 simulates the electrode placement on the human head, providing markings for easy positioning.
