[0028] Reference Figure 1An embodiment of the present invention provides a monitoring device 1 for monitoring the state of a source box 2 in a source guide device 3, comprising: a camera device 11 and a display device 12, wherein the camera device 11 is disposed in the source guide device 3, and is used to capture an image indicating the state of the source box 2 in the source guide device 3; the display device 12 is disposed outside the source guide device 3 and connected to the camera device 11, and is used to display the above-mentioned image to indicate the state of the source box 2 in the source guide device 3.

[0029] The monitoring device 1 provided by the embodiment of the present invention comprises a camera device 11 and a display device 12, wherein the camera device 11 is arranged in the source guide device 3, and can be used to take an image indicating the state of the source box 2 in the source guide device 3; and the display device 12 connected to the camera device 11 is arranged outside the source guide device 3, and can be used to display the image taken by the camera device 11. Thus, the staff can monitor the state of the source box 2 in the source guide device 3 in real time through the display device 12, and timely know the state of the source box 2, especially the state when the source box 2 in the source guide device 3 is abnormal, so as to timely and accurately handle the abnormality.

[0030] Optionally, the display device 12 may be a display, or any other product or component with a display function, such as a mobile phone terminal, a tablet computer, a television, a laptop computer, etc. In addition, the display device 12 and the camera device 11 may be connected in a wired manner, such as a data line or cable connection, or in a wireless manner, such as wifi, Bluetooth, or infrared connection.

[0031] Since the high-energy rays generated by the radioactive nuclide source in the source box 2 may affect the normal operation of the electronic components in the imaging device 11, and thus the stability of the imaging device 11, in order to alleviate the above problem, in one embodiment of the present invention, reference is made to Figure 2 The monitoring device 1 may further include a reflective member 13 disposed in the source guide device 3. The camera of the imaging device 11 faces the reflective member 13, so as to capture an image indicating the state of the source box 2 in the source guide device 3 by means of the reflection effect of the reflective member 13. In this way, the camera of the imaging device 11 can avoid being directly opposite to the source box 2, thereby preventing the high-energy rays generated by the radioactive nuclide source in the source box 2 from passing through the camera of the imaging device 11 and radiating to the electronic components behind the camera, thereby affecting the normal operation of the electronic components, thereby ensuring that the clarity of the image captured by the imaging device 11 can meet the requirements.

[0032] The reflector 13 can be any object capable of reflecting light. For example, the reflector 13 can be a reflector, etc. The reflector 13 can be arranged in the source guide channel 31 of the source guide device 3 as required, or can be arranged in a Figure 2 The shielding body 32 of the source guide device 3 shown is not specifically limited here.

[0033] In another embodiment of the present invention, referring to Figure 2 and Figure 3 The monitoring device 1 may further include a shielding shell 14, which covers the camera device 11. A through hole A is provided on the shielding shell 14 at a position corresponding to the camera head of the camera device 11, so that light can pass through the through hole A into the camera head of the camera device 11. The shielding shell 14 can shield the camera device 11, thereby preventing the high-energy rays generated by the radioactive nuclide source in the source box 2 from affecting the normal operation of the camera device 11, thereby ensuring the stability of the operation of the camera device 11.

[0034] The shielding shell 14 is made of shielding material, and the shielding material may be one or more of lead, tungsten, tungsten alloy, and lead alloy, so that the shielding shell 14 can block high-energy rays, thereby shielding the camera device 11.

[0035] It should be noted that in other embodiments of the present invention, the monitoring device 1 may also include a reflector 13 and a shielding shell 14 at the same time. The specific configuration is the same as that in the above embodiment and will not be described in detail here.

[0036] There can be one or more camera devices 11. When there are multiple camera devices 11, the shooting range can be increased. Of course, there can also be one or more reflective elements 13. When there is one reflective element 13, the cameras of the camera device 11 can all be facing the reflective element 13. When there are multiple reflective elements 13, multiple reflective elements 13 can correspond one-to-one to the cameras of multiple camera devices 11.

[0037] When there are multiple camera devices 11, the multiple camera devices 11 are respectively used to capture images indicating the status of the source box 2 at different positions in the source guide device 3, so that the source box 2 at different positions in the source guide device 3 can be captured by the camera devices 11, thereby increasing the monitoring range of the source box 2.

[0038] Reference Figure 1The source guide channel 31 of the source guide device 3 includes a first channel section 31a and a second channel section 31b which are connected. The first channel section 31a is used to connect with the first source storage device 4, and the second channel section 31b is used to connect with the second source storage device 5, wherein the first source storage device 4 can be a source tank, and the second source storage device 5 can be a radiotherapy device; thus, the source box 2 can enter the first channel section 31a of the source guide channel 31 after being moved out of the source tank, and can enter the second channel section 31b of the source guide channel 31 through the first channel section 31a, and can enter the radiotherapy device through the second channel section 31b, thereby realizing the introduction of the radioactive nuclide source; the source box 2 can also enter the second channel section 31b of the source guide channel 31 after being moved out of the radiotherapy device, and can enter the first channel section 31a of the source guide channel 31 through the second channel section 31b, and can enter the source tank through the first channel section 31a, thereby realizing the export of the radioactive nuclide source.

[0039] Reference Figure 2 and Figure 3 In this embodiment, the camera device 11 includes a first camera device and a second camera device. The first camera device is used to capture an image indicating the state of the source box 2 in the first channel section 31a, and the second camera device is used to capture an image indicating the state of the source box 2 in the second channel section 31b. The state of the source box 2 in the first channel section 31a and the second channel section 31b is monitored one by one by the first camera device and the second camera device. On the one hand, the monitoring range of the source box 2 is increased, and on the other hand, the problem of cost waste caused by too many camera devices 11 is avoided.

[0040] Reference Figure 3 When there are multiple camera devices 11, the multiple camera devices 11 are arranged side by side, so that the positions of the multiple camera devices 11 are relatively close, which can be easily disassembled and assembled.

[0041] Furthermore, the monitoring device 1 also includes a handle 15, which is connected to a plurality of camera devices 11 arranged side by side. Thus, the plurality of camera devices 11 arranged side by side can be loaded into or removed from the source guide channel 31 together through the handle 15, further facilitating assembly and disassembly.

[0042] Reference Figure 1The embodiment of the present invention further provides a source guiding system, comprising the monitoring device 1 described in any of the above embodiments, and also comprising a source box 2, a source guiding device 3, a first source storage device 4 and a second source storage device 5, wherein the source guiding device 3 comprises a shielding body 32, a source guiding channel 31 is arranged in the shielding body 32, and the source guiding channel 31 is used for the source box 2 in the first source storage device 4 to pass through and enter the second source storage device 5. The first source storage device 4 may be a source tank, and the second source storage device 5 may be a source carrier for accommodating the source box 2 in the radiotherapy device; in this way, the source box 2 enters the source guiding channel 31 after being moved out of the source tank, and enters the radiotherapy device after passing through the source guiding channel 31, thereby realizing the introduction of the radionuclide source; the source box 2 may also enter the source guiding channel 31 after being moved out of the radiotherapy device, and enter the source tank after passing through the source guiding channel 31, thereby realizing the export of the radionuclide source.

[0043] In the source guiding system provided by the embodiment of the present invention, the monitoring device 1 includes a camera device 11 and a display device 12, wherein the camera device 11 is arranged in the source guiding device 3 and can be used to take an image indicating the state of the source box 2 in the source guiding device 3; and the display device 12 connected to the camera device 11 is arranged outside the source guiding device 3 and can be used to display the image taken by the camera device 11. Therefore, the staff can monitor the state of the source box 2 in the source guiding device 3 in real time through the display device 12, and timely know the state of the source box 2, especially the state when the source box 2 in the source guiding device 3 is abnormal, so as to timely and accurately handle the abnormality.

[0044] In order to ensure that the source box 2 can smoothly enter the second source storage device 5 from the first source storage device 4 through the source guide channel 31, refer to Figure 4 and Figure 5 In this embodiment, a limiting structure 33 is provided in the second channel section 31b of the source guide channel 31 for docking with the second source storage device 5. The limiting structure 33 is used to prevent the source box 2 from rotating in a plane perpendicular to the extension direction of the second channel section 31b, thereby ensuring that the source box 2 can be aligned with the entrance of the second source storage device 5, thereby ensuring that the source box 2 can smoothly enter the second source storage device 5 from the second channel section 31b.

[0045] Furthermore, the limiting structure 33 can be disposed below the source box 2 to support and prevent the source box 2 from rotating, or disposed above the source box 2 to prevent the source box from rotating, or disposed above and below the source box 2 at the same time. Figure 5 As shown, the limiting structure 33 is a supporting block for supporting the source box 2 and can prevent the source box 2 from rotating.

[0046] In order to improve the stability of supporting the source box 2, the supporting surface B of the limiting structure 33 in this embodiment is an inclined surface. Of course, the supporting surface B of the supporting block can also be other shapes, such as a stepped surface. Compared with the stepped surface, the inclined surface can increase the contact area with the source box 2, thereby improving the stability of supporting the source box 2.

[0047] In one embodiment of the present invention, a guide surface is provided on the side of the limiting structure 33 away from the second source storage device 5, and the guide surface is arranged adjacent to the support surface B. The guide surface is used to guide the source box 2 to the support surface B of the support block, so that the source box 2 can slide onto the support surface B of the support block more smoothly.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
