Description

Technical Field

[0001] This utility model relates to the field of nuclear medicine radiation shielding technology, specifically a radiation protection operating table. Background Technology

[0002] The installation and use of SPECT / CT and PET / CT devices require extensive experimental work during the testing, installation, commissioning, and trial operation phases. For small animal SPECT / CT and PET / CT, repeated testing on live small animals as subjects, serving as the target for subsequent commissioning and calibration, is one of the main steps in small animal SPECT / CT and PET / CT experiments. This application primarily focuses on small animal SPECT / CT and PET / CT experiments, but can also be applied to similar technologies or testing scenarios.

[0003] Although small animals are the experimental subjects, procedures such as injections and animal positioning require human intervention. These personnel work all day and are very concerned about radiation. However, current technology does not adequately address radiation protection for personnel involved in this process, as positioning and injections are often performed precisely before testing to ensure the validity of experimental results. Therefore, what we need is effective shielding of personnel from radiation emitted from the direction of the equipment, in addition to contact with the experimental animals. This is a point of great concern to us.

[0004] In practice, operators face the challenge of shielding themselves from radiation from the instrument when handling experimental animals, performing specific injections and positioning, and minimizing the time the animals are exposed to the shielding when handling them. They also need to ensure their entire body is protected from radiation while the instrument is running, thus maintaining overall shielding against radiation interference throughout the entire process.

[0005] Existing technologies also have some shielding barriers, such as CN206340351U and KR10-1598972B1, but these shielding barriers are relatively bulky and not suitable for PET / CT positioning and injection in small animals. Vertical lead glass is not conducive to observing small animals, and only a glove hole is provided. Due to the precision of the injection operation, it is difficult to meet the actual needs of this application.

[0006] While existing technologies have developed relatively simple portable shielding devices for nuclear medicine, their designs suffer from several shortcomings: First, the height is not adjustable. Given the varying heights of operators, a single device cannot meet the needs of multiple people. With teams consisting of shorter and taller individuals, is it feasible to provide each person with their own operating table? This is a very practical problem. Second, there is a lack of adequate lighting. Actual operation on laboratory animals reveals that room lighting is often insufficient, and injecting laboratory animals is many times more difficult than injecting humans or large animals. Dedicated and effective lighting is essential. Third, as in this technology, the operating table is too small, even for mouse operations (many items need to be placed during the procedure, not just syringes, injection solutions, and mice). The small size also increases the risk of equipment falling and breaking. Fourth, even simply expanding the work surface area is insufficient for general operations. Gauze, syringes, needles, etc., take up too much space on the work surface. In addition, injection operations often generate dirt, and there is no place to put the dirt on the work surface. More importantly, if personnel frequently go to other places (outside the radiation shielding range) to get other materials or dispose of garbage because there is not enough space on the work surface, it will increase the risk of radiation exposure.

[0007] These shortcomings, as far as existing technology can be seen, have not been addressed with effective solutions or measures. According to our company's market inquiries, most radiation shielding stations cannot meet the above-mentioned problems. There is currently no operating station that meets the actual needs of operators. Summary of the Invention

[0008] The purpose of this utility model is to provide a device that addresses the problem that existing technologies lack a shielding device specifically designed for the placement and injection of small animals, or that existing devices are too simple in function and do not meet the requirements of on-site operation. This approach is original to this application and is not inspired by any existing technology.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a radiation protection operating table, characterized in that it includes an upper shielding part, an operating table, a lifting system, and a movable base connected sequentially from top to bottom.

[0010] The upper shielding part includes an illumination part, a viewing window, and a middle plate; the upper shielding part is connected and fixed to the front edge of the operating table; the viewing window is set at an angle.

[0011] The operating table includes an operating surface, a storage box, and a disinfection supply box; the operating surface is fan-shaped when viewed from above, the storage box is fixed to one side below the operating surface, the disinfection supply box is fixed to the other side below the operating surface, and the operating surface is fixed above the lifting system.

[0012] The lifting system has an inner frame and an outer frame, both of which have a square cross-section when viewed from above. The upper end of the inner frame is equipped with a hydraulic lifting unit, and the upper end of the outer frame is fixed relative to the hydraulic lifting unit.

[0013] The mobile base includes a base plate, a control box, a foot switch, and a set of moving wheels. The lower surface of the inner frame is fixed to the upper surface of the base plate, the control box and the foot switch are fixed to the upper surface of the base plate, and the set of moving wheels includes a plurality of moving wheels, which are evenly distributed on the outer side of the lower surface of the base plate.

[0014] Furthermore, the outer shell material of the lighting unit, viewing window panel, middle plate, work surface, storage box, disinfection supply box, inner frame, outer frame, base plate, and control box is selected from one or more of the following combinations: stainless steel plate, lead plate, barium sulfate plate, neutron shielding plate, radiation-proof magnesium alloy plate, and boron-containing polymer material plate.

[0015] The lighting unit features downward-facing LED lights powered by a rechargeable battery.

[0016] The window embedded in the viewing panel is made of radiation-shielding lead glass.

[0017] The narrowest part of the middle plate in the horizontal direction shall not be less than 25cm.

[0018] The work surface has a waste inlet that works with a storage box, and the waste inlet is equipped with an inlet cover.

[0019] The storage box can be rotatably mounted under the work surface and can be rotated outwards from one edge of the work surface.

[0020] Compared to the outer diameter of the inner frame, the inner diameter of the outer frame is at least 1 mm longer in both length and width; the upper surface of the hydraulic lifting unit has an area of ​​not less than 50 square centimeters.

[0021] The fixing rod of the hydraulic lifting unit is fixed on the bottom groove inside the inner frame.

[0022] The power input terminal of the hydraulic lifting unit is electrically connected to the circuit inside the control box, and the lifting terminal of the hydraulic lifting unit is connected to the output terminals of the foot switch and the lowering switch, respectively.

[0023] Each moving wheel has a self-locking mechanism.

[0024] Compared to existing technologies, this application has several non-obvious advantages: First, it provides better protection. Compared to the shielding device of CN114601490A, the upper, middle, and lower parts of this application offer significantly larger and more comprehensive protection for the operator, taking into account the possibility that the operator may move left and right and not be completely centered, thus ensuring higher safety from the design. Second, it provides better lighting conditions. This application is specifically equipped with an LED lighting system, making it easy to operate under higher lighting conditions. Although generally there is an ambient light source (indoor lighting) for operations, a dedicated light source can significantly improve working conditions, which is a beneficial design. Third, the operating table is ingeniously designed. Not only is the area large, but the use of storage boxes and sterilization supply boxes further improves the utilization rate of the table surface—waste and frequently used items (sterilization supplies, needles) do not occupy the table surface, which can be used solely for handling experimental animals. Moreover, the table surface is significantly larger than the shielding device of CN114601490A. Fourth, by arranging the operating table above the lifting system, the height of the device can be easily adjusted, which not only accommodates different users, but also sometimes the same person needs to adjust the height due to different postures (when handling mice or larger experimental animals, in injection or non-injection states).

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] A radiation protection operating console, characterized in that it comprises, from top to bottom, an upper shielding part, an operating table, a lifting system, and a movable base connected in sequence. The upper shielding part, the operating table, the lifting system, and the movable base are connected adjacent to each other, for example, by welding, or by using pre-set interlocking joints plus screws / riveting, or by using pre-set screw holes and corresponding screws for fixing.

[0035] The upper shielding section includes an illumination unit, a viewing window, and a middle plate. The upper shielding section is fixed to the front edge of the workbench. The viewing window is angled. The illumination unit, for example, uses an LED light source, and can be single or multiple. A viewing window is embedded in the viewing window, most commonly made of lead glass, but other common transparent / semi-transparent materials can also be used. The middle plate is most commonly rectangular, serving as a connecting element, supporting the illumination unit and viewing window. To prevent hand injuries, the sides of the middle plate can be curved inwards, minimizing the risk of hand contact.

[0036] The operating table includes an operating surface, a storage box, and a disinfection supply box. The operating surface, viewed from above, is fan-shaped. The storage box is fixed to one side below the operating surface, and the disinfection supply box is fixed to the other side below the operating surface. The operating surface is fixed above the lifting system. In the shielding device of CN114601490A, the operating surface is a very narrow square, which is difficult to meet experimental needs. A common design here is a fan-shaped section, meaning it is fan-shaped when viewed from above, with the connection to the middle plate generally being straight or slightly curved. This provides significantly more operating surface area on both sides, making operation more convenient. The storage box and disinfection supply box are located on opposite sides under the operating surface and can be interchanged. However, considering that more people are right-handed, placing the disinfection supply box on the right side is more common and suitable for most users. The disinfection supply box uses a pivot-type fixing mechanism, meaning it can rotate left and right around the pivot of the fixing part. When rotating inward, the table surface can shield it from dust, and when rotating outward, it allows for easy access to the contents. The storage box is used to store disinfected waste. It works with a storage opening, which is, for example, round, and can be equipped with a lid that can be opened or rotated. The storage box can be designed as a drawer, with the inner drawer removable for easy disposal of the stored waste.

[0037] The lifting system consists of an inner frame and an outer frame, both with a square cross-section when viewed from above. A hydraulic lifting unit is located at the upper end of the inner frame, and the upper end of the outer frame is fixed relative to the hydraulic lifting unit. Both the inner and outer frames are, for example, hollow and made of panels. The lower end of the hydraulic lifting unit is inserted into the inner frame and can move freely up and down within its stroke. The upper end of the hydraulic lifting unit is, for example, flat, to facilitate its fixation with a flange / protrusion inside the outer frame. The power and control lines of the lifting unit, for example, pass through the lower part of the inner frame and are secured with fasteners, leading to the movable base.

[0038] The mobile base includes a base plate, a control box, a foot switch, and a set of casters. The lower surface of the inner frame is fixed to the upper surface of the base plate. The control box and foot switch are also fixed to the upper surface of the base plate. The casters consist of a plurality of casters evenly distributed on the outer side of the lower surface of the base plate. The control box connects the hydraulic lifting unit and the foot switch and provides power, which can be a lithium battery or an external power source. There are at least four swivel casters.

[0039] Furthermore, the outer shell material of the lighting unit, viewing window panel, middle plate, work surface, storage box, disinfection supply box, inner frame, outer frame, base plate, and control box is selected from one or more of the following combinations: stainless steel plate, lead plate, barium sulfate plate, neutron shielding plate, radiation-proof magnesium alloy plate, and boron-containing polymer material plate.

[0040] The lighting unit features downward-facing LED lights, which can be composite light groups powered by rechargeable batteries.

[0041] The window embedded in the viewing panel is made of radiation-shielding lead glass.

[0042] The narrowest part of the middle plate in the horizontal direction shall not be less than 25cm.

[0043] The work surface has a waste inlet that mates with a storage box, and the waste inlet is fitted with an inlet cover. The inlet cover is, for example, round.

[0044] The storage box can be rotatably mounted under the work surface and can be rotated outwards from one edge of the work surface.

[0045] Compared to the outer diameter of the inner frame, the inner diameter of the outer frame is at least 1 mm longer in both length and width; the upper surface of the hydraulic lifting unit has an area of ​​not less than 50 square centimeters and is flat or substantially flat.

[0046] The fixing rod of the hydraulic lifting unit is fixed on the bottom groove inside the inner frame.

[0047] The power input terminal of the hydraulic lifting unit is electrically connected to the circuit inside the control box, and the lifting terminal of the hydraulic lifting unit is connected to the output terminals of the foot switch and the lowering switch, respectively.

[0048] Each moving wheel has a self-locking mechanism.

[0049] Example 2

[0050] Most of the information is the same as in Example 1. The difference is that the lighting unit is an integrated battery lamp in which the mount and housing, LED light and lithium battery are integrated.

[0051] The window is either fan-shaped or trapezoidal.

[0052] The two sides of the middle plate are recessed inward at sharp angles (forming acute angles).

[0053] The disinfection supply box is a drawer-type box that pulls outwards and retracts inwards. It can be pulled out horizontally and pushed in horizontally.

[0054] Both the inner and outer frames have a trapezoidal cross-section when viewed from above, with the wider side closer to the operator.

[0055] The movable wheel set is designed so that at least half of each wheel is embedded in the base plate, making it more stable.

[0056] The control box is equipped with a lithium battery to power the lifting mechanism, eliminating the need for external wiring for the entire device.

[0057] Example 3

[0058] The back and viewing window of the device in this application have a protection equivalent of ≥5mmpb, and the tabletop has a lifting distance of ≥30cm.

[0059] The entire structure is movable, making it easy to move and operate.

[0060] The base plate can be recessed slightly on the side closest to the operator, or it can be installed more towards the side where the non-operator is standing, making it easier for the operator to place their feet.

[0061] The area of ​​the viewing window should be no less than 40cm x 40cm to facilitate operation.

[0062] The operating table described in this application is used in the following manner: First, anesthetize the experimental animal. Then, the operator powers on the operating table, replaces the LED batteries with fully charged ones, places the anesthetized animal on the table, and adjusts the table height to suit the operator's needs. After adjustment, the operator stands on the outside of the operating table (towards the viewing window), extends their arms from both sides of the central panel, and performs the injection on the experimental animal. They then retrieve the injection medication, syringes, and pillow from the sterilization container, and dispose of waste in the storage box. After the operation, the operating table is pushed forward until it is close to the instrument, and the experimental animal is placed on the instrument for testing. Throughout the entire process, most of the operator's body, especially the torso, is not exposed, providing excellent protection.

[0063] The purpose of this application is to obtain image data of laboratory animals. This image data itself does not represent disease or pathological results, but is only intermediate data, generally PET or CT data, or other common test data involved in nuclear medicine.

[0064] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
