[0027] Example 1

[0028] See attached document Figure 1-5 The mobile radiation protection nursing vehicle for nuclear medicine departments shown includes a vehicle body 1, a front panel 11 and two side panels 12. A placement tray 2 is provided on the front side of the front panel 11. A protective plate 3 is provided on the outer wall of the side panel 12. A connecting rod 13 is connected to the inner wall of the side panel 12. A seat 4 is detachably provided at the front end of the connecting rod 13. A threaded adjustment mechanism 5 is provided between the placement tray 2 and the front panel 11.

[0029] By installing a front panel 11 and side panels 12 on the vehicle body 1, a complete protective structure is formed, providing reliable shielding protection for nuclear medicine work. The placement tray 2 on the front side of the front panel 11 can be used to place medications, tools, or related instruments, providing a convenient working platform for operators. A protective plate 3 is installed on the outer wall of the side panel 12, and a connecting rod 13 is connected to the inner wall of the side panel 12. A seat 4 is further installed at the front end of the connecting rod 13, allowing medical staff to rest when needed. A threaded adjustment mechanism 5 is provided between the front panel 11 and the placement tray 2, allowing for flexible adjustment of the height of the placement tray 2 to meet the needs of different operating scenarios and enhance the versatility and applicability of the nursing vehicle.

[0030] The threaded adjustment mechanism 5 includes a motor 51, a first bevel gear 52, a second bevel gear 53, and an adjusting rod 54. The motor 51 is mounted on the front plate 11, which has a fixed seat 15 for mounting the adjusting rod 54. The output end of the motor 51 is fixedly connected to the first bevel gear 52. The second bevel gear 53, which meshes with the first bevel gear 52, is sleeved on the adjusting rod 54. The placement disk 2 is movably connected to the adjusting rod 54. The adjusting rod 54 includes a rotating shaft 541 and a lead screw 542. The second bevel gear 53 is sleeved on the rotating shaft 541. The bottom of the placement disk 2 has a lead screw nut 55 that matches the lead screw 542. The threaded adjustment mechanism 5 drives the first bevel gear 52 to rotate via the motor 51, which in turn drives the second bevel gear 53, which meshes with the first bevel gear, to rotate synchronously. This, in turn, drives the rotating shaft 541, which is fixedly connected to the second bevel gear 53, to rotate, thereby causing the lead screw 542 to rotate. Since a lead screw nut 55 is provided between the lead screw 542 and the placement tray 2, the height of the placement tray 2 also changes with the rotation of the lead screw 542. Through this structural design, the height of the placement tray 2 can be precisely adjusted as the adjusting rod 54 rotates, thus meeting the needs of medical staff to adjust the height of the placement platform according to their own operational requirements, and improving the operational convenience of the nursing cart.

[0031] The side plate 12 and the protective plate 3 are connected by a spring 31. The spring 31 connection between the side plate 12 and the protective plate 3 is designed to effectively absorb the vibration and impact generated during a collision of the nursing vehicle, which is often in poor visibility during movement, thus protecting the equipment and items inside the vehicle body 1 from damage.

[0032] A pair of radiation-proof gloves 6 are installed through the front panel 11. These gloves 6, made of high-density radiation-proof material, effectively block radioactive radiation leakage. Operators can use the radiation-proof gloves 6 to perform delicate operations on pharmaceuticals or related instruments in a closed environment, avoiding direct contact with radioactive materials and ensuring the safety and accuracy of the operation.

[0033] Furthermore, the front panel 11 is provided with a radiation-proof observation window 7. The radiation-proof observation window 7 on the front panel 11 is made of lead glass or other radiation-proof transparent materials, which has excellent radiation shielding effect and clear visibility. Medical staff can monitor the working status of the operating area in real time through the observation window to ensure the accuracy of drug dispensing or equipment debugging, while avoiding misoperation or safety hazards caused by blind spots.

[0034] The vehicle body 1 is equipped with casters 16 at the bottom to facilitate the movement of the nursing vehicle.

[0035] Example 2

[0036] Based on Embodiment 1, Embodiment 2 provides a specific structure of a seat 4. The connecting rod 13 is provided with a hinge 14. The seat 4 includes a threaded rod 41, an anti-slip support pad 42, and a seat cushion 43. The threaded rod 41 is threaded through the connecting rod 13. The bottom of the threaded rod 41 is connected to the anti-slip support pad 42, and the top of the threaded rod 41 is connected to the seat cushion 43.

[0037] The hinge 14 on the connecting rod 13 allows the connecting rod 13 to be folded when the seat 4 is removed, facilitating the movement of the entire nursing cart. When nurses need to perform procedures for extended periods, the connecting rod 13 can be folded horizontally, and the seat 4 can then be installed on the connecting rod 13. The anti-slip support pad 42 connected to the bottom of the threaded rod 41 increases friction with the ground, improving the stability of the nursing cart and preventing it from shifting unnecessarily. The seat cushion 43 connected to the top is made of soft and comfortable material, providing good support and comfort for medical staff, thereby reducing fatigue from prolonged operations and improving work efficiency.

[0038] The inner wall of the side panel 12 is also provided with a storage box 17. The storage box 17 can provide additional storage space for medical staff and can hold the disassembled seat 4 without affecting the movement of the nursing cart.

[0039] Specific application examples:

[0040] When handling radiopharmaceuticals, the specific application method of the nuclear medicine-specific radiation-proof mobile nursing vehicle of this application is as follows:

[0041] First, the nursing cart is moved to the treatment area using the casters 16. If the nursing cart accidentally collides with the wall during the movement, the protective plate 3 contacts the wall, and the compression spring 31 of the protective plate 3 acts as a buffer, effectively absorbing the vibration and impact generated when the nursing cart collides, and protecting the equipment and items inside the cart 1 from damage.

[0042] Upon reaching the area requiring treatment, lift the connecting rod 13, turn the threaded rod 41 into it, and then rotate the anti-slip support pad 42 under the threaded rod 41. The anti-slip support pad 42 increases friction with the ground, improving the stability of the nursing cart and preventing it from moving unnecessarily. When the seat 4 is needed, the seat cushion 43 can be rotated onto the top of the threaded rod 41, providing good support and comfort for medical staff, thereby reducing fatigue from prolonged operation and improving work efficiency.

[0043] The motor 51 is started according to its own operating needs, driving the first bevel gear 52 to rotate, which in turn drives the second bevel gear 53 meshing with it to rotate synchronously, and drives the rotating shaft 541 fixedly connected to the second bevel gear 53 to rotate together, thereby driving the lead screw 542 to rotate. Since there is a lead screw nut 55 between the lead screw 542 and the placement plate 2, the height of the placement plate 2 also changes with the rotation of the lead screw 542.

[0044] The operator inserts both hands into the radiation-proof gloves 6 on the front panel 11 and monitors the working status of the operating area in real time through the radiation-proof observation window 7 on the front panel 11 to ensure the accuracy of drug dispensing or equipment debugging, while avoiding misoperation or safety hazards caused by blind spots.

[0045] After the operation is completed, remove seat 4 and put it into the storage box 17 next to it.
