Technical Field

[0001] This utility model generally relates to the field of medical protective equipment technology, and more specifically, to a protective face shield for monitoring the dosage of the eye lens. Background Technology

[0002] Nuclear radiation technology is widely used in the medical field, such as digital subtraction angiography (DSA) using X-rays, PET imaging for diagnostic radionuclide F-18, and radioactive seed implantation therapy. Personnel working in these fields are called radiation workers. During their work, radiation workers may be exposed to ionizing radiation hazards such as X-rays or gamma rays. The lens of the eye, as a typical radiation-sensitive organ, is at risk of clouding or even blindness if exposed to excessive radiation doses. According to the "Regulations on Occupational Health Management of Radiation Workers," optimal protective measures must be taken to protect radiation workers from or minimize the harm of ionizing radiation. Furthermore, personal dosimeters must be used to record the occupational exposure levels of radiation workers and conduct personal dose monitoring.

[0003] Currently, lead face shields on the market only have protective functions. However, according to the UK Ionizing Radiation Regulation (IRR17) and the relevant instructions on lens dosimeters in the International Commission on Radiological Protection Report No. 139, it is also necessary to compare and monitor the individual dose at the corresponding left corner of the eye and the middle of the eyes on the inside of the face shield. Therefore, it is of great significance to design an X-ray and gamma-ray protective face shield with lens dose monitoring function. Utility Model Content

[0004] This application provides a protective face shield for monitoring the dose of the eye lens to solve the above-mentioned technical problems.

[0005] This application provides a protective face shield for monitoring ocular lens dosage, comprising: a lead face shield, a dosimeter box, an arc-shaped slide rail, and a magnetic slider. The arc-shaped slide rail is disposed on the side of the lead face shield away from the wearing side, and the magnetic slider is movably disposed on the arc-shaped slide rail. The dosimeter box is disposed on the side of the lead face shield close to the wearing side, and the dosimeter box and the magnetic slider are magnetically connected to each other across the lead face shield.

[0006] According to some embodiments of the present invention, the arc-shaped slide rail is arranged laterally on the top of the lead screen.

[0007] According to some embodiments of the present invention, the magnetic slider includes a first magnetic block and a handle. The first magnetic block is disposed at one end of the handle and is movably disposed within the arc-shaped slide rail. The handle protrudes from the outside of the arc-shaped slide rail.

[0008] According to some embodiments of the present invention, the dosimeter box includes a second magnetic block, a thermoluminescent detector, and a housing.

[0025] like Figure 1 and Figure 2 As shown in the embodiment, a protective face shield for monitoring ocular lens dosage includes: a lead face shield 1, a dosimeter box 2, an arc-shaped slide rail 3, and a magnetic slider 4. The lead face shield 1 is positioned away from the wearing side of the arc-shaped slide rail 3, and the magnetic slider 4 is movably mounted on the arc-shaped slide rail 3. The dosimeter box 2 is positioned near the wearing side of the lead face shield 1, and the dosimeter box 2 and the magnetic slider 4 are magnetically connected to the lead face shield 1. This application effectively provides protection by using the lead face shield 1, reducing the harm of ionizing radiation to the wearer. Simultaneously, the lead face shield 1 allows nearsighted individuals to use it while wearing their own glasses, making it highly adaptable. By moving the magnetic slider 4 along the arc-shaped slide rail 3, and because the magnetic slider 4 is magnetically connected to the dosimeter box 2, the dosimeter box 2 will move synchronously with the magnetic slider 4, thereby changing the relative position of the dosimeter box 2 to the wearer's eyes. This allows the dosimeter box 2 to perform comparative monitoring of the wearer's left corner of the eye and the position between the two eyes, without removing the lead face shield 1. This allows operation from the side away from the wearer, making it convenient to use. It is worth noting that the above structure does not penetrate the lead face shield 1, therefore it does not affect the protective effect.

[0026] like Figure 1 As shown, in some embodiments of this utility model, the arc-shaped slide rail 3 is horizontally arranged on the top of the lead face shield 1. The arc-shaped slide rail 3 conforms to the arc surface of the lead face shield 1 and is horizontally arranged, covering any horizontal position from the wearer's left eye to their right eye, so that the dosimeter box 2 can monitor from any position. Simultaneously, it can be adjusted to accommodate the unique facial features of different individuals, avoiding obstruction of vision. At the same time, the arc-shaped slide rail 3 restricts the vertical movement of the magnetic slider 4, ensuring that the magnetic slider 4 will not slide downwards due to gravity during use, thus affecting its use.

[0027] like Figure 3As shown, in some embodiments of this utility model, the magnetic slider 4 includes a first magnetic block 5 and a handle 6. The first magnetic block 5 is disposed at one end of the handle 6 and is movably disposed within the arc-shaped slide rail 3. The handle 6 protrudes from the arc-shaped slide rail 3. The handle 6 is located away from the wearing side, allowing operation without removing the lead face shield 1 from the wearing side. The handle 6 moves the first magnetic block 5 within the arc-shaped slide rail 3, thereby moving the dosimeter box 2.

[0028] like Figure 3 As shown, in some embodiments of this utility model, the dosimeter box 2 includes a second magnetic block 7, a thermoluminescent detector 8, and a housing 9. The second magnetic block 7, corresponding to the first magnetic block 5, is embedded in the upper part of the housing 9. A slot for accommodating the thermoluminescent detector 8 is provided in the lower part of the housing 9, and the thermoluminescent detector 8 is disposed within the slot. The first magnetic block 5 and the second magnetic block 7 are magnetically connected, similar to the principle of magnetic glass wipes in the prior art, enabling the dosimeter box 2 and the magnetic slider 4 to move synchronously with the lead-resistant face shield 1. The thermoluminescent detector 8, disposed within the slot of the housing 9, monitors the side of the face shield 1 closest to the wearer, thus providing better monitoring of the protective effect.

[0029] like Figure 3 As shown, in some embodiments of this utility model, a sealing cover 10 is provided at the opening of the slot. The sealing cover 10 is assembled with the opening to facilitate opening or closing, and to facilitate the removal or placement of the thermoluminescent detector 8.

[0030] In some embodiments of this invention, the thermoluminescent detector 8 employs a LiF-sensitized disc. The LiF-sensitized disc is finely processed, with a smooth surface, a diameter of 1 cm, and a thickness of 0.5 mm. LiF material possesses excellent thermoluminescent properties, enabling precise recording of radiation dose. The sensitized disc is doped with trace amounts of Mg and Cu elements, enhancing its sensitivity and stability. During use, when the disc is exposed to a radiation environment, electrons within the LiF crystal are excited and store energy. When heated, this stored energy is released in the form of light, and the radiation dose can be calculated by measuring the intensity of the released light. This detector is widely used in nuclear medicine, radiation protection, and environmental monitoring, and its high precision and reliability make it an indispensable tool.

[0031] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0032] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application.
