Description

Technical Field

[0001] The invention relates to the technical field of radiation protection, and in particular to a movable double-ray radiation protection device. Background Art

[0002] Commonly used radiation protection equipment and items on the market are mainly lead screens, lead suits, and single-site lead shields, which are mainly for X-rays. The imaging of nuclear medicine is to introduce trace tracers synthesized from trace radionuclides required for the examination into the human body, and then use special in vitro detectors (gamma cameras, SPECT, PET) to detect the distribution of these nuclides in various organs in the body, and use computer tomography to display the physiological metabolic functions of the target parts or major organs of the human body, and make a diagnosis in combination with the anatomical structure positioning provided by CT. These radionuclide tracers will release gamma rays during the decay process in the body, so this examination not only has X-rays generated by conventional medical imaging equipment such as DR and CT, but also gamma rays.

[0003] At present, the main imaging equipment in mainstream nuclear medicine departments include gamma cameras, SPECT / CT (single photon emission tomography / X-ray computed tomography), and PET / CT (positron emission tomography / X-ray computed tomography). The principle is to confirm the distribution of radionuclides in the subject's body by measuring the gamma photons emitted by the subject's body, and then accurately locate them in combination with CT technology. Nuclear medicine patients often include cancer patients, children, and some people with limited mobility who have developed their diseases to the middle and late stages and are in poor physical condition, and sometimes need a caregiver. Nuclear medicine examinations not only contain X-rays for conventional medical radiological examinations, but also gamma rays for the application of nuclear technology, which forces the caregiver to face the issue of radiation safety. The examination room is generally equipped with protective lead clothing and related protective supplies, but conventional protective supplies are mainly aimed at X-ray protection, and the protective effect is limited.

[0004] Gamma rays have shorter wavelengths than X-rays, higher energy, and stronger penetrating power. Ordinary radiation protection products are vulnerable to gamma rays, which will increase the risk of radiation hazards for clinical caregivers. To address this issue, a mobile visual radiation protection device specifically for caregivers in nuclear medicine examination rooms is designed to effectively protect against both X-rays and gamma rays, ensuring the safety of patients while also raising the radiation safety of caregivers to a higher level.

[0012] As a preferred embodiment of the present invention: a group of fixing plates are fixed to the top outer wall of the rotating frame, an air guide tube is fixed to the top outer wall of the fixing plates, the telescopic bellows is connected to one end of the air guide tube, and the other end of the air guide tube passes through the outer wall of the rotating tube.

[0015] On the basis of the above-mentioned solution: a second sliding block is fixed to the outer wall of the support frame, and the second sliding block is slidably connected to the bottom outer wall of the annular slide rail.

[0016] Based on the above scheme, it is preferred that: a hydraulic power unit is fixed to the top outer wall of the rotating tube, handles are fixed to the outer walls on both sides of the hydraulic power unit, a control switch is provided on the outer wall of the hydraulic power unit, and a magnetic baffle is fixed to the bottom outer wall of the pressing block.

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention is a radiation protection facility for both gamma rays and X-rays, which can effectively protect against gamma rays and X-rays. It is more comprehensive than conventional radiation protection products that only protect against X-rays. At the same time, it allows the caregiver to observe the patient's condition without restriction and ensure the radiation safety of the caregiver to the greatest extent. At the same time, the position of the protective equipment can be planned in advance according to the needs of the caregiver, and the protective equipment can be moved to the location required by the caregiver before the inspection begins through the universal wheels at the bottom of the protective equipment.

[0019] 2. When the caregiver inside the protective equipment needs to move heavy protective equipment, he first steps on the pedal with both feet. When the pedal is compressed, the internal gas will be filled into the cylinder through the air duct and the air duct metal tube, and the hydraulic cylinder is pushed downward by the output shaft of the cylinder to tilt at a corresponding angle, so that the friction surface of one side of the metal friction plate connected to the outer wall of the pressure block is pressed against the ground. Then the caregiver presses the control switch to turn on the hydraulic power unit, and the output shaft of the hydraulic cylinder is driven by the hydraulic power unit to move forward at a constant speed. The friction between the metal friction plate and the ground pushes the protective equipment as a whole to move at a constant speed in the corresponding direction. The caregiver does not need to push it manually, and can easily push the protective equipment to move at a constant speed inside the protective equipment.

[0020] 3. When the hydraulic cylinder pushes the metal friction plate forward a corresponding distance, the hydraulic cylinder will stop pushing the metal friction plate forward. At this time, the inertia of the overall forward movement of the protective equipment will be offset by the friction between the metal friction plate and the ground, allowing the protective equipment to stop stably at the corresponding position.

[0021] 4. When the caregiver needs to change the moving direction of the protective equipment, he / she first removes his / her feet from the pedal. At this time, the pedal will move upward and reset under the elastic force of the spring. When the airbag expands, the gas previously filled into the cylinder will be sucked back through the air guide tube and the air guide metal tube, so that the hydraulic cylinder can rotate upward to a corresponding angle and reset under the traction of the guide sleeve and the connecting frame. At this time, the metal friction plate will leave the ground, and then the caregiver can easily turn the rotating tube by the handle to adjust the direction of the support frame fixed at the bottom of the rotating tube, thereby completing the adjustment of the moving direction of the protective equipment, allowing the caregiver inside the protective equipment to flexibly move the protective equipment, thereby improving the flexibility of the protective equipment.

[0022] 5. When the cylinder lifts the hydraulic cylinder upward and resets it through the connecting frame and the guide sleeve, the metal friction plate connected to the outer wall of the pressing block will rotate toward the side of the pressing block due to its own gravity. At this time, the magnetic baffle on one side of the pressing block will block the metal friction plate and fix the metal friction plate by its own magnetic force to prevent the metal friction plate from shaking freely on the outer wall of the pressing block.

[0039] A square lead glass window 6 of 500mm×500mm is embedded above the lead door 7. A second lead plate 10 of 1200mm high and 200mm wide is placed on both sides below the lead door 7.

The position can be planned in advance according to the needs of the accompanying personnel, and the protective device can be moved to the location required by the accompanying personnel through the universal wheels 9 at the bottom of the protective device before the inspection begins.

[0044] like Figure 4-8 As shown, the bottom inner wall of the first lead plate 1 is rotatably connected to a rotating tube 18, the bottom outer wall of the rotating tube 18 is fixed to a support frame 29, a group of connecting blocks 27 are respectively fixed at both ends of the support frame 29, a hydraulic cylinder 30 is rotatably connected to the outer wall of one side of the connecting block 27, a pressure block 32 is fixed to the output shaft of the hydraulic cylinder 30, the outer wall of the pressure block 32 is rotatably connected to a metal friction plate 31, and a layer of friction pad is provided on the bottom outer wall of the metal friction plate 31;

[0045] A rotating frame 17 is fixed to the outer wall of the rotating tube 18, and the rotating frame 17 is slidably connected to the bottom inner wall of the first lead plate 1. A group of air bags 16 are fixed to the inner wall of the rotating frame 17, and a pedal 34 is fixed to the top outer wall of the air bags 16. The pedal 34 is slidably connected to the inner wall of the rotating frame 17. A telescopic bellows 38 is fixed to the top outer wall of the air bags 16, and the telescopic bellows 38 penetrates the top outer wall of the pedal 34.

[0046] A set of fixing plates 37 are fixed to the top outer wall of the rotating frame 17, an air guide tube 36 is fixed to the top outer wall of the fixing plates 37, a telescopic bellows 38 is connected to one end of the air guide tube 36, and the other end of the air guide tube 36 passes through the outer wall of the rotating tube 18;

[0047] An annular slide rail 23 is fixed to the outer wall of the bottom of the first lead plate 1, and a group of first sliders 25 are slidably connected to the inner wall of the annular slide rail 23. A cylinder 24 is fixed to the outer wall of the bottom of the first slider 25. A connecting frame 26 is fixed to the output end of the cylinder 24. A guide ring 28 is rotatably connected to the inner wall of the connecting frame 26. The guide ring 28 is slidably connected to the outer wall of the hydraulic cylinder 30. An air guide metal tube 33 is arranged on the inner wall of the first slider 25. One end of the air guide metal tube 33 is connected to the input end of the cylinder 24, and the other end of the air guide metal tube 33 passes through the outer wall of one side of the rotating tube 18 and is connected to one end of the air guide tube 36.

[0048] A group of springs 35 are fixed to the bottom outer wall of the pedal 34, and the bottom outer wall of the spring 35 is fixed to the bottom inner wall of the rotating frame 17;

[0049] A second slider 39 is fixed to the outer wall of the support frame 29, and the second slider 39 is slidably connected to the bottom outer wall of the annular slide rail 23;

[0050] A hydraulic power unit 21 is fixed to the top outer wall of the rotating tube 18 , handles 20 are fixed to the outer walls on both sides of the hydraulic power unit 21 , a control switch 22 is provided on the outer wall of the hydraulic power unit 21 , and a magnetic baffle 40 is fixed to the bottom outer wall of the pressing block 32 .

[0051] In order to improve the protective effect of the protective device against the two types of radiation, the protective device uses a plurality of heavy first lead plates 1, second lead plates 10, side lead glass 3 and top lead glass 4, so the overall weight of the protective device will exceed 300 kilograms. Therefore, it is difficult for the caregiver to push the care device to move in the treatment room. Therefore, when the caregiver inside the protective device needs to move the heavy protective device, he first steps on the pedal 34 with both feet. After the pedal 34 is compressed, the internal gas will be filled into the cylinder 24 through the air guide tube 36 and the air guide metal tube 33, thereby pushing the connecting frame 26 and the guide ring 28 downward through the output shaft of the cylinder 24. The guide ring 28 pushes the hydraulic cylinder 30 connected to one side of the support frame 29 to tilt downward at a corresponding angle, so that the friction surface of one side of the metal friction plate 31 connected to the outer wall of the pressure block 32 is against the ground. Then the caregiver presses the control switch 22 to turn on the hydraulic power unit 21, so that the output shaft of the hydraulic cylinder 30 is driven forward at a uniform speed by the hydraulic power unit 21. The friction between the metal friction plate 31 and the ground pushes the protective device as a whole to move at a uniform speed in the corresponding direction. The caregiver does not need to push it manually, and can easily push the protective device to move at a uniform speed inside the protective device.

[0052] When the hydraulic cylinder 30 pushes the metal friction plate 31 forward a corresponding distance, the hydraulic cylinder 30 will stop pushing the metal friction plate 31 forward. At this time, the inertia of the overall forward movement of the protective device will be offset by the friction between the metal friction plate 31 and the ground, so that the protective device can stably stop at the corresponding position.

[0053] When the caregiver needs to change the moving direction of the protective device, he first removes his feet from the pedal 34. At this time, the pedal 34 will move upward and reset under the elastic force of the spring 35, so that the airbag 16 will be re-inflated. When the airbag 16 is inflated, the gas previously filled into the cylinder 24 will be sucked back through the air guide tube 36 and the air guide metal tube 33, so that the hydraulic cylinder 30 can be rotated upward by a corresponding angle and reset under the traction of the guide ring 28 and the connecting frame 26. At this time, the metal friction plate 31 connected to the outer wall of the pressing block 32 will leave the ground, and then the caregiver can easily rotate the rotating tube 18 through the handle 20 to adjust the direction of the support frame 29 fixed at the bottom of the rotating tube 18. Then the caregiver steps on the pedal 34 again and repeats the above steps. The protective device can be pushed to move at a uniform speed in the corresponding direction through the hydraulic cylinder 30, thereby completing the adjustment of the moving direction of the protective device, allowing the caregiver inside the protective device to flexibly move the protective device, thereby improving the flexibility of the protective device.

[0054] When the cylinder 24 lifts the hydraulic cylinder 30 upward and resets it through the connecting frame 26 and the guide ring 28, the metal friction plate 31 rotatably connected to the outer wall of the pressing block 32 will rotate toward the side of the pressing block 32 due to its own gravity. At this time, the magnetic baffle 40 on one side of the pressing block 32 will block the metal friction plate 31 and adsorb and fix the metal friction plate 31 through its own magnetic force to prevent the metal friction plate 31 from shaking freely on the outer wall of the pressing block 32 as a whole.

[0055] When the rotating tube 18 rotates, it can drive the first slider 25 to slide on the inner wall of the annular slide rail 23 through the air-guiding metal tube 33 on the outer wall. At the same time, the air-guiding metal tube 33 can support the cylinder 24 and the first slider 25 as a whole. When the rotating tube 18 drives the support frame 29 to rotate, the second slider 39 located on the outer wall of the support frame 29 will also slide on the inner wall of the annular slide rail 23, thereby supporting and guiding the support frame 29 as a whole during rotation.

[0056] When the present embodiment is in use, the caregiver first steps on the pedal 34 with both feet. When the pedal 34 is pressurized, the internal gas will be filled into the cylinder 24 through the air guide tube 36 and the air guide metal tube 33, thereby pushing the connecting frame 26 and the guide sleeve 28 downward by a corresponding distance through the output shaft of the cylinder 24, so that the guide sleeve 28 pushes the hydraulic cylinder 30 connected to one side of the support frame 29 to tilt downward by a corresponding angle, so that the friction surface of one side of the metal friction plate 31 connected to the outer wall of the pressure block 32 is against the ground, and then the caregiver presses the control switch 22 to turn on the hydraulic power unit 21, thereby driving the output shaft of the hydraulic cylinder 30 to move forward at a uniform speed through the hydraulic power unit 21, and the friction between the metal friction plate 31 and the ground pushes the protective equipment as a whole to move at a uniform speed in the corresponding direction.

[0057] When the caregiver needs to change the moving direction of the protective equipment, he first removes his feet from the pedals 34. At this time, the pedals 34 will move upward and reset under the elastic force of the springs 35, so that the airbag 16 will re-inflate. When the airbag 16 expands, the gas previously filled into the cylinder 24 will be sucked back through the air guide tube 36 and the air guide metal tube 33, so that the hydraulic cylinder 30 will rotate upward by a corresponding angle and reset under the traction of the guide collar 28 and the connecting frame 26. At this time, the metal friction plate 31 connected to the outer wall of the pressure block 32 will leave the ground, and then the caregiver can easily rotate the rotating tube 18 through the handle 20 to adjust the direction of the support frame 29 fixed at the bottom of the rotating tube 18. Then the caregiver steps on the pedal 34 again and repeats the above steps to push the protective equipment to move at a uniform speed in the corresponding direction through the hydraulic cylinder 30, thereby completing the adjustment of the moving direction of the protective equipment.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
