Description

Technical Field

[0001] The present disclosure relates to the field of medical devices, and in particular to a camera for a magnetoencephalogram and a magnetoencephalogram. Background Art

[0002] Magnetoencephalography (MEG) is a brain function detection technology that non-invasively detects electromagnetic physiological signals of the brain. It plays an important role and has broad application prospects in brain science research and clinical diagnosis of neurological diseases.

[0003] In order to improve the accuracy of the test results, during the magnetoencephalography test, the operator of the magnetoencephalography instrument needs to confirm that there are no abnormal phenomena that affect the test results during the entire test process, such as the head movement of the subject, the subject not completing the test accurately according to the test process, etc. At the same time, the operator also needs to ensure that when the subject encounters an emergency, it can be discovered and handled in the first time. Therefore, a camera needs to be set up in the magnetoencephalography instrument so that the operator can always observe the status of the subject. How to design a camera that can be used in the magnetoencephalography instrument is a key issue in the current magnetoencephalography technology. Summary of the invention

[0004] The present application aims to at least solve the technical problem of the lack of a camera suitable for a magnetoencephalogram in the background art. To this end, one purpose of the present application is to provide a camera for a magnetoencephalogram to cope with the complex and diverse monitoring requirements in magnetoencephalogram detection.

[0005] According to one aspect of the present disclosure, a camera for a magnetoencephalogram is provided, comprising: a camera assembly; a camera fixing assembly, configured to provide an installation space for the camera assembly to fix the camera assembly; a moving assembly, movably connected to the camera fixing assembly, configured to drive the camera fixing assembly to move; and a slide rail assembly, movably connected to the moving assembly, configured to provide a moving track for the moving assembly.

[0006] According to another aspect of the present disclosure, a magnetoencephalogram is provided, comprising the camera in the above embodiment.

[0007] In the present disclosure, the camera assembly is fixed in the camera fixing assembly, and the multi-directional movement of the camera is achieved through the moving assembly and the slide rail assembly. While making full use of the limited space in the magnetoencephalogram, the camera's monitoring blind spots are reduced, fully meeting the complex and diverse monitoring requirements in magnetoencephalography detection.

[0008] These and other aspects of the disclosure will be apparent from and elucidated with reference to the embodiments described hereinafter. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0017] Magnetoencephalography (MEG) is a brain function detection technology that non-invasively detects electromagnetic physiological signals of the brain. It plays an important role and has broad application prospects in brain science research and clinical diagnosis of neurological diseases.

[0018] In order to improve the accuracy of the test results, during the magnetoencephalogram test, the operator of the magnetoencephalogram needs to confirm that there are no abnormal phenomena that affect the test results during the entire test process, such as the head movement of the subject, the subject not completing the test accurately according to the test process, etc. At the same time, the operator also needs to ensure that when the subject encounters an emergency, it can be discovered and handled in the first time. Therefore, a camera needs to be set up in the magnetoencephalogram so that the operator can always observe the status of the subject.

[0019] Conventional cameras can only capture limited angles and directions after being fixed, while in the magnetoencephalogram detection process, images of different angles and directions need to be collected according to different monitoring needs. If conventional cameras are used, in order to meet the complex and changeable monitoring needs, it is necessary to set up multiple cameras at different positions in the magnetoencephalogram. However, due to the limited space inside the magnetoencephalogram and the large size of conventional cameras, when installed on the magnetoencephalogram, it will hinder the person being tested from entering and exiting the magnetoencephalogram and is not conducive to the detection operation. In addition, conventional cameras will generate large magnetic field interference when working. Since the magnetoencephalogram is very sensitive to magnetic field detection, conventional cameras will interfere with the normal operation of the magnetoencephalogram and cannot be used in the magnetoencephalogram.

[0020] The present disclosure proposes a camera for a magnetoencephalogram, in which a camera module is fixed in a camera fixing component, and the camera can be moved in all directions through a moving component and a slide rail component, so that blind spots in monitoring can be reduced as much as possible in the limited space inside the magnetoencephalogram, a larger range of monitoring can be achieved, and the complex and changeable monitoring requirements in the magnetoencephalogram detection process can be met.

[0021] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0022] Figure 1 FIG. 1 is a schematic diagram of a camera 100 for a magnetoencephalography device according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the camera 100 includes a camera assembly (not shown), a camera fixing assembly 110 , a moving assembly 120 and a slide rail assembly 130 .

[0023] The camera fixing assembly 110 is configured to provide an installation space for the camera assembly so as to fix the camera assembly.

[0024] The moving assembly 120 is movably connected to the camera fixing assembly 110 and is configured to drive the camera fixing assembly 110 to move.

[0025] The slide rail assembly 130 is movably connected to the moving assembly 120 and is configured to provide a moving track for the moving assembly 120 .

[0026] The camera assembly is used to collect monitoring images and is composed of components such as a camera circuit board. In some embodiments, the camera assembly can be controlled by corresponding software to collect images of the required monitoring location. The software can be stored in the camera circuit board or in a control device (e.g., a host computer, etc.) that is connected to the camera.

[0027] The camera assembly is installed in the camera fixing assembly 110, and the structure of the camera fixing assembly 110 can be designed according to the structure of the camera assembly. In some embodiments, for different camera assemblies, camera fixing assemblies 110 with different structures can be used; in order to improve the versatility of the camera fixing assembly 110, the structure of the camera fixing assembly 110 and the mounting hole position for mounting the camera assembly can also be fixed, and the camera assembly can be adaptively designed according to the structure and the mounting hole position.

[0028] Since the magnetoencephalogram is very sensitive to magnetic field interference, in order to reduce the impact on the magnetoencephalogram detection results, it is necessary to avoid using metal screws when installing the camera component. Non-metallic screws or adhesives can be used instead.

[0029] In some embodiments, none of the camera fixing assembly 110, the moving assembly 120, and the slide rail assembly 130 include magnetic materials. Conventional cameras often have large magnetic field interference, which will cause the magnetoencephalogram to fail to work properly, and therefore cannot be used in the magnetoencephalogram. The use of non-magnetic materials can minimize the magnetic field interference of the camera on the magnetoencephalogram and improve the accuracy of the detection results. On this basis, in order to further reduce the interference to the magnetoencephalogram, the installation position of the camera 100 can also be designed, for example, it can be set at a position away from the magnetic field sensor in the magnetoencephalogram. In one example, when the camera 100 is installed at a distance of more than 1 meter from the magnetic field sensor, the magnetic field interference generated will be less than 0.1 nanotesla (nT).

[0030] In some embodiments, the camera fixing assembly 110 includes a camera fixing frame 111 and a switching block 112 .

[0031] The camera fixing frame 111 is configured to define an installation space for the camera assembly.

[0032] The adapter block 112 is fixedly connected to the camera fixing frame 111 and movably connected to the moving component 120 .

[0033] In some embodiments, the camera assembly includes a lens 141. The camera fixing frame 111 is provided with a lens hole 1111. The lens hole 1111 is configured to accommodate the lens 141 so that the lens 141 does not protrude from the outer contour of the camera fixing assembly 110.

[0034] like Figure 2 and Figure 3 As shown, the camera assembly is installed in the camera fixing frame 111. The position of the lens hole 1111 on the camera fixing frame 111 corresponds to the lens 141 in the camera assembly, and the lens hole 1111 can be set higher than the lens 141, so as to protect the lens 141 and reduce the risk of the lens 141 being damaged. Figure 5 An example of lens aperture 1111 is shown in FIG. Figure 5 In the example, the thickness of the camera fixing frame 111 changes gradually and reaches a maximum at the lens hole 1111. In other embodiments, the thickness of the camera fixing frame 111 may also be set to a fixed value, which is not limited in the present disclosure.

[0035] In some embodiments, the adapter block 112 includes at least one adjustable fastener 1121. The at least one adjustable fastener 1121 is configured to enable the camera fixing assembly 110 to achieve one of the following functions:

[0036] The camera fixing assembly 110 rotates relative to the moving assembly 120; or

[0037] The camera fixing assembly 110 is fixed relative to the moving assembly 120 .

[0038] like Figure 2 As shown, two adjustable fasteners 1121 are provided on the adapter block 112. The adjustable fasteners 1121 may use adjustable screws or the like. When the adjustable fasteners 1121 are adjusted, the degree of fastening between the adapter block 112 and the mobile component 120 may be adjusted, so that the position of the camera fixing component 110 relative to the mobile component 120 may be adjusted, so that the camera 100 can collect images at the corresponding position according to monitoring requirements. In some embodiments, when the monitoring requirements change, the adjustable fasteners 1121 may be loosened, and after the camera fixing component 110 is adjusted to the required position, the adjustable fasteners 1121 may be tightened so that the camera fixing component 110 is fixed at the position for image collection.

[0039] In some embodiments, Figure 2 As shown, the moving assembly 120 includes a sliding member 121 and a ball head connecting member 122 .

[0040] The sliding member 121 is slidably connected to the slide rail assembly 130 and is configured to slide along the moving track.

[0041] The ball head connector 122 is fixedly connected to the sliding member 121 and is movably connected to the camera fixing assembly 110 .

[0042] Figure 4 An example of the moving assembly 120 is shown in FIG. The sliding member 121 can slide in the slide rail assembly 130, thereby driving the camera fixing assembly 110 to move to a desired position in the direction of the moving rail. The adapter block 112 can rotate around the ball head connector 122, thereby driving the camera fixing assembly 110 to rotate to a desired angle. Figure 4In the example shown, the adapter block 112 is configured to be composed of two sub-blocks. The two sub-blocks are fixed by an adjustable fastener 1121. When the adjustable fastener 1121 is adjusted, the clamping force of the two sub-blocks on the ball head connector 122 changes, thereby realizing the rotation and fixation of the camera fixing assembly 110.

[0043] In some embodiments, the slide rail assembly 130 includes a slideway 131 . The slideway 131 is movably connected to the moving assembly 120 and is configured to define a moving track of the moving assembly 120 .

[0044] In some embodiments, the slideway 131 is disposed on a side of the slide rail assembly 130 facing the moving assembly 120 .

[0045] like Figure 5 and Figure 6 As shown, the movable component 120 drives the camera fixing component 110 to move along the slide 131. Since the opening direction of the slide 131 is toward the side where the movable component 120 is located, when the movable component 120 moves along the slide 131, the space on the side of the slide rail component 130 toward the movable component 120 can be fully utilized.

[0046] In some embodiments, the camera assembly includes a signal cable (not shown). The rail assembly 130 also includes a positioning groove 132. The positioning groove 132 is connected to the slideway 131 and is configured to accommodate the signal cable. The extending direction of the positioning groove 132 is parallel to the extending direction of the slideway 131.

[0047] The signal cable of the camera assembly realizes the communication between the camera 100 and the control system (e.g., a host computer, etc.), and can transmit the collected image information and data information such as control instructions between the camera 100 and the control system. In some embodiments, the signal cable can also be made of non-magnetic materials to reduce the magnetic field interference to the magnetoencephalogram.

[0048] like Figure 5 As shown, the positioning groove 132 is arranged in parallel with the slideway 131. The width and depth of the positioning groove 132 can be designed according to the size of the signal cable, which is convenient for moving the camera assembly and reduces the probability of abnormalities such as cable entanglement and cable disengagement. In addition, the relative position relationship between the positioning groove 132 and the slideway 131 can also be designed according to the use requirements. Figure 5 In the example shown, the positioning groove 132 and the slide 131 are arranged on the same side of the slide rail assembly 130, both facing the moving assembly 120, but in other usage scenarios, the positioning groove 132 and the slide 131 can also be arranged on opposite sides of the slide rail assembly 130, for example, respectively arranged on the side of the slide rail assembly 130 facing the moving assembly 120 and the side away from the moving assembly 120.

[0049] In some embodiments, the slideway 131 is provided with a positioning structure (not shown) configured to limit the movement of the moving assembly 120 along the moving track so that the moving assembly 120 is positioned at a corresponding position of the slideway assembly 130 .

[0050] During the magnetoencephalogram test, it is sometimes necessary to monitor the subject at multiple angles. The mobile component 120 can move along the slide 131 to a suitable monitoring position to monitor the subject. The positioning structure can be configured to cooperate with the sliding member 121 in the mobile component 120, for example: it can be configured to be a gear or rack that meshes with each other, an elastic boss and a positioning hole, etc., or the friction between the sliding member 121 and the positioning structure can be used to fix the mobile component 120 at the monitoring position. In some embodiments, the signal cable received in the positioning slot 132 can also assist in positioning the mobile component 120.

[0051] In some embodiments, the moving track is arc-shaped, and the center of the arc faces the moving component 120 .

[0052] In order to monitor the subject more accurately, the sliding track of the moving component 120 can be set to an arc shape. When the moving component 120 moves along the arc track, the distance between it and the subject is relatively consistent. In some embodiments, in order to adapt to the structure of the magnetoencephalogram, the body of the slide rail component 130 can also be designed to be arc-shaped. Since the shielding space for performing magnetoencephalogram detection on the subject in the magnetoencephalogram is usually set to be approximately cylindrical, the arc-shaped slide rail component is easier to install and saves installation space.

[0053] Based on the same inventive concept, the present disclosure also provides a magnetoencephalogram, comprising the camera 100 in the above embodiment.

[0054] A specific embodiment of the present application is described below. It should be understood that this specific embodiment is described for illustrative purposes only and should not be interpreted as limiting the present application.

[0055] The camera 100 installed in the magnetoencephalogram includes a camera assembly, a camera fixing assembly 110, a moving assembly 120, and a slide rail assembly 130. The camera fixing assembly 110, the moving assembly 120, and the slide rail assembly 130 are all made of non-magnetic materials.

[0056] The slide rail assembly 130 is an arc-shaped structure, and the center of the arc faces the moving assembly 120. A slideway 131 and a positioning groove 132 are provided on the side of the slide rail assembly 130 facing the moving assembly 120. The positioning groove 132 accommodates the signal cable of the camera assembly. The moving assembly 120 moves in the slideway 131, thereby driving the camera fixing assembly 110 to move along the slideway 131. When the moving assembly 120 moves to the required monitoring position, the moving assembly 120 can be positioned there.

[0057] The moving assembly 120 includes a sliding member 121 and a ball head connector 122. The sliding member 121 is designed to match the slide rail. The ball head connector 122 is connected to the adapter block 112 in the camera fixing assembly 110. By adjusting the adjustable fastener 1121 on the adapter block 112, the camera fixing assembly 110 can be rotated to the required monitoring position and positioned there.

[0058] The camera assembly is installed in the camera fixing frame 111 in the camera fixing assembly 110. A lens hole 1111 is provided on the camera fixing frame 111, corresponding to the position of the lens 141 in the camera assembly. The structure of the camera fixing frame 111 at the lens hole 1111 is designed to be protruding from the lens 141, thereby achieving a protective effect on the lens 141.
