Description

Technical Field

[0001] The present invention relates to the technical field of radiotherapy transportation, and specifically provides a patient mobile transportation device for magnetic resonance examination. Background Art

[0002] Magnetic resonance imaging (MRI) is a key examination method in tumor diagnosis and treatment planning, which can provide high-resolution soft tissue images to help doctors accurately locate the lesion area. After the patient completes the magnetic resonance examination, they need to be transported to the radiotherapy room for subsequent treatment, radiotherapy preparation and implementation.

[0003] In the prior art, the transfer of patients from the magnetic resonance examination bed to the radiotherapy treatment bed often relies on manual handling or simple trolleys. There are problems such as difficulty in maintaining the patient's body position stable, inconvenient manual handling, which may affect the accuracy of radiotherapy positioning and treatment effect. At the same time, the auxiliary fixation devices, monitoring instruments carried by the patient and the metal items that the patient may have themselves, if not effectively detected and managed, may pose potential hazards to the safe operation of radiotherapy equipment and the patient's body.

[0004] In addition, the radiotherapy environment has extremely high hygiene requirements for patient transportation equipment. If the frequently used transportation device is not properly disinfected, it is likely to become a hidden danger of cross-infection, increasing the risk of patient infection.

[0005] The existing Chinese patent with the publication number CN111097109A discloses a positioning transfer bed. This device semi-automatically moves the transfer bed. When fixing the body position, first drive the movable column to rise by a driving motor, so that the carbon fiber bed can rise at the same time, and then manually pull the carbon fiber bed horizontally to the final position, which shortens the time spent in the whole process to a certain extent and speeds up the whole treatment process. However, the handling of patients and the operations before movement during use are relatively cumbersome.

[0006] Therefore, there is an urgent need for a fast and safe transportation device for radiotherapy patients that integrates automatic metal detection, patient body position stability, intelligent information synchronization and efficient disinfection functions to ensure the smooth connection of patients from magnetic resonance examination to radiotherapy, improve treatment safety and comfort, and meet the clinical radiotherapy's demand for high-quality transportation equipment.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a patient mobile transfer device for magnetic resonance examination, including a bottom frame 1, a lifting device 2 is arranged on the upper side of the bottom frame 1, a transfer plate 3 is arranged on the upper side of the lifting device 2, the bottom frame 1 is connected to the transfer plate 3 through the lifting device 2, a detection mechanism 4 and a transfer mechanism 5 are arranged on the upper side of the transfer plate 3, and a control module 6 is also fixedly connected to the upper side of the bottom frame 1;

[0033] The detection mechanism 4 includes a fixing component and a coil 406 inside the fixing component. The detection mechanism 4 also includes a metal detection module 409.

The upper side of the mobile pile 501 is fixedly connected to a hydraulic lifting module 504. The upper end of the hydraulic lifting module 504 is fixedly connected to a mounting frame 507. The lower end of the mounting frame 507 is fixedly connected to a limit rod 505. The lower side of the limit rod 505 is plugged into the inside of the mobile pile 501. A disinfection mechanism 506 is also provided between the two mobile piles 501. One side of the mounting frame 507 is fixedly connected to a second motor 508. The side of the mounting frame 507 close to the detection mechanism 4 is fixedly connected to an inner cylinder 514. The inner cylinder 514 is fixedly connected to the inner cylinder 515. The outer wall of the second motor 508 is sleeved with an outer cylinder 509, the inner wall of the outer cylinder 509 is fixedly connected to a limit block 510, one side of the limit block 510 extends to the inside of the inner cylinder 514, the output end of the second motor 508 is fixedly connected to a threaded rod 511, the threaded rod 511 is located inside the inner cylinder 514, and the outer wall of the threaded rod 511 is threadedly connected to the inner wall of the limit block 510, the middle part of the outer wall of the outer cylinder 509 is fixedly connected to a visual recognition module 513, the outer wall of the outer cylinder 509 is also provided with two hooks 512, the upper ends of the two hooks 512 are fixedly connected to the outer wall of the outer cylinder 509, and the inner cylinder 514 is provided with a There is a slide groove running through the upper and lower parts, an opening running through the upper and lower parts is opened on the lower side of the outer cylinder 509, and a circular hole running through both sides is opened on the limit block 510. The position of the hook 512 is set corresponding to the position of the fixing ring 408. The first motor 503, the hydraulic lifting module 504, the second motor 508, the hook 512 and the visual recognition module 513 are all electrically connected to the control module 6, and the two movable piles 501 can move relative to each other. The second motor 508 can drive the outer cylinder 509 to move away from the second motor 508 or close to the second motor 508. The movement stroke of the outer cylinder 509 is greater than the width of the mattress 403;

[0038] After the device is moved to one side of the magnetic resonance examination machine, the hook 512 can be hung on the fixed ring 408, and then the hydraulic lifting module 504 is started to lift the mounting bracket 507 upward. During this process, the outer cylinder 509 drives the hook 512, the fixed ring 408, and the hanging cloth 407 to rise. When the lower side of the hanging cloth 407 moves to the upper side of the bracket 401, the hydraulic lifting module 504 is stopped. Then, the second motor 508 is started to drive the threaded rod 511 to rotate. Since the outer wall of the threaded rod 511 is threadedly connected to the inner wall of the limit block 510, and the limit block 510 is fixedly connected to the outer cylinder 509, the limit block 510 will drive the outer cylinder 509 to translate along the inner cylinder 514. Then, the hanging cloth 407 carrying the patient is lifted onto the examination bed of the magnetic resonance examination machine or moved from the magnetic resonance examination machine to the device and transported to the radiotherapy area, avoiding manual movement of the patient and reducing the patient's body movement to complete convenient examination.

[0039] Embodiment 3:

[0040] Please refer to Figures 1 - 6 , based on Embodiment 1 and Embodiment 2, a technical solution is provided: when the patient is transferred from the hospital bed to the upper side of the hanging cloth 407, when the pressure detection module 402 detects pressure, the first motor 503 will be started, and the first motor 503 will drive the bidirectional threaded rod 502 to rotate through the bevel gear set, so that the two moving piles 501 move towards the middle. When the two moving piles 501 move to the middle, the bidirectional threaded rod 502 is reversely driven to reset the two moving piles 501. During this process, the visual recognition module 513 collects the patient's facial information and inputs it into the control module 6, which is synchronized with the patient's medical record information in the hospital database, so that the device can conveniently synchronize the patient information. When the pressure on the upper side of the pressure detection module 402 disappears, the control module 6 provides the confirmation information that the patient has been examined to the database, so as to conveniently synchronize the patient's examination information. During the movement of the two visual recognition modules 513, the head and foot positions of the patient can be recorded and input into the control module 6 respectively. At the same time, the control module 6 combines the pressure information provided by the pressure detection module 402 to automatically adjust the height difference between the two hydraulic lifting modules 504 when the patient is subsequently transferred to the magnetic resonance examination machine and the radiotherapy treatment bed, avoiding the neck arch caused by the deformation of the head cloth surface during lifting due to the patient not lying in the central position on the upper side of the hanging cloth 407, and keeping the patient's body posture as straight as possible;

[0041] Specifically: L: total length of the transfer cloth, l: patient's height, m: patient's mass, x: horizontal distance from the patient's head to the left hook, θ1, θ2: angles between the left and right cloth surfaces and the horizontal plane, T1, T2: tensions of the left and right hooks, h1, h2: initial lifting heights of the left and right hooks, Δh: height adjustment amount;

[0042] The geometric relationship between the patient's head position and the hook satisfies:

[0043]

[0044] where y is the vertical offset of the patient's head position caused by gravity;

[0045] The vertical force balance is: T1sinθ1 + T2sinθ2 = mg;

[0046] The horizontal force balance is: T1cosθ1 = T2cosθ2;

[0047] The depression amount y of the cloth surface is approximately a quadratic function:

[0048]

[0049] Minimize the inclination angle of the patient's head to avoid arching:

[0050] φ = θ1 - α

[0051] By adjusting h1 and h2 to make φ → 0, we get:

[0052]

[0053] The height difference between the hooks on both sides should satisfy:

[0054]

[0055] In this process, the mass is obtained through the pressure detection module 402, the patient's position is obtained through the visual recognition module 513, and the stiffness k of the preset hanging cloth 407 is set;

[0056] Example 4:

[0057] Please refer to Figures 1 - 6 , based on Example 1, Example 2, and Example 3, a technical solution is provided: The disinfection mechanism 506 includes an atomizer 601. The outer wall of the atomizer 601 is fixedly connected to the upper side of the transfer plate 3. The input end of the atomizer 601 is fixedly connected to a liquid inlet pipe 605. The outer wall of the transfer plate 3 is also fixedly connected to a water storage tank 602. One end of the liquid inlet pipe 605 away from the atomizer 601 is fixedly connected to the outer wall of the water storage tank 602. The inside of the water storage tank 602 is communicated with the input end of the atomizer 601 through the liquid inlet pipe 605. The output end of the atomizer 601 is fixedly connected to a mist discharge pipe 603. One side outer wall of the inner cylinder 514 close to the second motor 508 is fixedly connected to a connecting pipe 604. One end of the mist discharge pipe 603 away from the atomizer 601 is communicated with the inside of the inner cylinder 514 through the connecting pipe 604;

[0058] After the device finishes transporting the patient, the pressure detection module 402 detects the disappearance of the upper pressure. At this time, the control module 6 executes a countdown. After a period of time, it self-drives the first motor 503 to move the two moving piles 501 towards each other and then move back to their original positions. During this process, the atomizer 601 is started to extract the disinfectant liquid inside the water storage tank 602 through the liquid inlet pipe 605, atomize it, and then input it into the mist discharge pipe 603. The disinfected mist is input into the interior of the inner cylinder 514 through the mist discharge pipe 603 and the connecting pipe 604. Subsequently, the mist evenly diffuses downward through the opening on the lower side of the outer cylinder 509. Since the outer cylinder 509 is in a moving state, the device can be evenly disinfected against germs, enabling the device to quickly complete disinfection and facilitating the operation conditions of frequent transportation.
