DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The embodiment of the present application discloses a patient transfer assistance system for medical imaging scanning equipment.

[0030] Reference Figure 1 , Figure 2 as well as Figure 3 The patient transfer auxiliary system for medical imaging scanning equipment includes a bed 1, a transfer mechanism 2, and a control module 3. The support column of the bed 1 is provided with wheels, and handrails are installed at both ends of the bed 1 to facilitate pushing and transferring the bed 1. It should be noted that the height of the bed 1 is higher than the height of the detection table. The transfer mechanism 2 includes a transfer platform 4 and a lateral pushing component 5. The transfer platform 4 includes a panel 41, a base 42 and a lifting component 43. The base 42 is located on the upper surface of the bed 1. The lateral pushing component 5 is located on one side of the bed 1 along its width direction and is used to push the base 42 to move along the width direction of the bed 1. The lifting component 43 is built into the base 42 and is provided with a lifting part 432. The panel 41 is arranged above the base 42 and the bottom surface of the panel 41 abuts against the lifting part 432. Support components 411 for supporting the detection table of the scanning equipment are respectively provided at both ends of the bottom surface of the panel 41, and the base 42 is located between the two support components 411.

[0031] A groove 421 is provided on the bottom surface of the removal side of the base 42, and a laser distance sensor 422 is arranged in the groove 421. One end of the laser distance sensor 422 is fixedly connected to the bottom of the groove 421 by bolts, and the detection end of the laser distance sensor 422 is arranged vertically downward. The laser distance sensor 422 is used to detect whether the base 42 is located above the detection table. The control module 3 includes a PLC control mainboard and a battery. The PLC control mainboard and the battery are fixedly connected to the bottom of the bed 1 by bolts. The horizontal pushing component 5, the lifting component 43 and the laser distance sensor 422 are respectively electrically connected to the control module 3;

[0032] Among them, the control module 3 is configured as follows:

[0033] 1) If a start signal is received, the lifting component 43 is controlled to move;

[0034] It is understandable that the start signal may be a signal triggered by the medical staff pressing a start button pre-set on the control module 3 .

[0035] 2) When the duration T1 is reached, the lateral pushing component 5 is controlled to move, and the detection value of the laser ranging sensor 422 is obtained at the same time;

[0036] It can be understood that the duration T1 is calculated based on the height to which the panel 41 needs to be raised and the speed at which the panel 41 is raised and lowered when the lifting assembly 43 is set in motion. The laser ranging sensor 422 is controlled to be actuated, i.e., the laser ranging sensor 422 is started, and the signal from the detection end of the laser ranging sensor 422 is recorded.

[0037] 3) If the detection value fed back by the laser ranging sensor 422 meets the preset panel 41 descending condition, the lifting assembly 43 is controlled to descend;

[0038] It is understandable that the preset panel 41 lowering condition is that the center of the base 42 is located at the center of the test platform, which can be implemented as follows:

[0039] According to the known speed v of the lateral pushing assembly 5 to lateral push the base 42 (that is, achieved by controlling the speed of the hydraulic cylinder 52 to extend and retract), and the distance d between the laser distance sensor 422 and the center of the base 42 (that is, according to the preset distance between the groove 421 and the center of the base 42 when the laser distance sensor 422 is installed), it can be known that:

[0040] s=v×t

[0041]

[0042] (Wherein, t is the time required for the laser ranging sensor 422 to detect the movement from one end of the detection platform to the other end, k is the extension amount of the lateral pushing component 5 required to meet the descending condition of the panel 41, and s is the width of the detection platform; wherein, the laser ranging sensor 422 can be started and the detection end of the laser ranging sensor 422 is moved out of the bed board 1 along with the base 42, that is, the laser signal of the detection end is not blocked, and then the time t is obtained by calculating the duration of the detection end signal being blocked when the laser ranging sensor 422 is pushed horizontally over the detection platform.)

[0043] 4) If a signal is received from the lifting assembly 43 that the lowering panel 41 has been completed, the lateral pushing assembly 5 is controlled to reset.

[0044] It can be understood that the signal fed back by the lifting component 43 after the panel 41 is lowered can be an electrical signal fed back after the lifting component 43 is lowered to the initial value.

[0045] Through the above arrangement, when it is necessary to transfer the patient to the testing equipment, the medical staff presses the start button, the lifting component 43 is activated, and after pushing the panel 41 to a preset height, the lateral pushing component 5 pushes the base 42 together with the panel 41 to the top of the testing table, and adjusts the lateral pushing component 5 through the feedback value of the testing table by the laser ranging sensor 422 until the lowering condition of the panel 41 is met, and controls the extension and retraction of the lifting component 43 to realize the lowering of the panel 41. Since a support component 411 is provided on the lower surface of the panel 41, the panel 41 can be placed on the testing table through the support component 411. After receiving the electrical signal fed back by the lifting component 43 for lowering the panel 41, the lateral pushing component 5 is reset to realize the process of transferring the patient to the medical imaging scanning testing table, thereby improving the efficiency of transferring patients during the medical imaging scanning process.

[0046] Reference Figure 2 and Figure 4 The lateral pushing assembly 5 includes a fixed block 51 and a hydraulic cylinder 52. The fixed block 51 is fixedly connected to the side wall of the bed body 1 along its width direction by bolts. The fixed block 51 is provided with a fixed groove 53 on the side wall facing the bed body 1. The cylinder body of the hydraulic cylinder 52 extends into the fixed groove 53 and is fixedly connected to the bottom of the fixed groove 53 by bolts. An arc groove 11 is penetrated through the upper surface of the bed body 1 along its width direction. The cylinder body of the hydraulic cylinder 52 extends into the arc groove 11, and its output end is extended along the opening direction of the arc groove 11. A connecting piece 54 is installed at the end of the output end of the hydraulic cylinder 52. The connecting piece 54 includes a curved block 55 fixed to the end of the hydraulic cylinder 52 by bolts. The curved block 55 is fixed by bolts. One end of the curved block 55 is welded to the bottom surface of the base 42, and the end of the curved block 55 away from the base 42 is arc-shaped, and the arc surface of the curved block 55 contacts the inner wall of the arc groove 11.

[0047] Reference Figure 2 , Figure 5 as well as Figure 6The lifting assembly 43 includes four hydraulic cylinders 431. The interior of the base 42 is hollow and the opening is upward. The cylinder body of the hydraulic cylinder 431 is fixed to the bottom of the inner cavity of the base 42 by bolts, and the output end of the hydraulic cylinder 431 is extended in the longitudinal direction. The opening of the base 42 is fixedly connected with a support plate 423 by bolts. The support plate 423 is penetrated with a positioning hole 424 for the output end of the hydraulic cylinder 431 to pass through. There are four lifting parts 432, and the four lifting parts 432 are respectively arranged at the ends of the output ends of the four hydraulic cylinders 431. The lifting part 432 includes a connecting block 4321, a fixed shaft 4322 and a roller 4323. The lower end of the connecting block 4321 is welded to the end of the output end of the hydraulic cylinder 431. The upper end of the connecting block 4321 is penetrated with a positioning groove 4324 along the width direction of the base 42. The two ends of the fixed shaft 4322 are respectively welded to the inner walls on both sides of the positioning groove 4324, and the roller 4323 is rotatably sleeved on the fixed shaft 4322 through a bearing. When the base 42, the panel 41 and the patient are transferred to the inspection table, the bottom of the support assembly 411 is supported on the inspection table, and the panel 41 is separated from the base 42 by resetting the hydraulic cylinder 52, thereby completing the transfer of the patient.

[0048] Reference Figure 7The support assembly 411 is a support block 412, which is welded to the lower surface of both ends of the panel 41, and the width of the support block 412 is greater than the width of the base 42. Through grooves 12 are opened at both ends of the upper surface of the bed body 1 along the width direction of the bed body 1, and the lower end of the support block 412 extends into the through groove 12, and the bottom surface of the support block 412 contacts the bottom surface of the through groove 12. It should be noted that the depth of the through groove 12 needs to be greater than the depth of the arc groove 11. Considering that when the hydraulic cylinder 42 pushes the base 42 laterally, the friction of the roller 4323 is small, and the panel 41 is easily moved relative to each other, a limit assembly 6 is set on the side wall of the base 42, and the limit assembly 6 includes a positioning column 61, two limit blocks 62 and a sliding block 63. One end of the positioning column 61 is welded to the side wall of the base 42, and the sliding block 63 is extended along the length direction of the base 42, and the sliding block 63 is penetrated and opened along the length direction thereof. The positioning column 61 is penetrated in the sliding groove, so that the sliding block 63 can be slidably sleeved on the positioning column 61, so that the sliding block 63 can move along the length direction thereof. The two limit blocks 62 are set on the side wall of the base 42, and the two limit blocks 62 are positioned The column 61 is arranged symmetrically with respect to the center, the cross-section of the limit block 62 is L-shaped and the L-shaped opening is arranged upward, the end of the horizontal section of the limit block 62 is welded to the side wall of the base 42, and the two horizontal sections of the limit block 62 are arranged horizontally, the sliding block 63 is located above the horizontal section of the limit block 62, and the lower surface of the sliding block 63 abuts against the upper surface of the horizontal section of the limit block 62, so that the sliding block 63 slides along the length direction of the base 42 with the positioning column 61 as the center, and when the sliding block 63 slides in the direction close to the support block 412, the side wall of the sliding block 63 facing the side of the base 42 abuts against the side wall of the support block 412, so that the panel 41 cannot slide along its width direction during the transfer process, thereby limiting the panel 41.

[0049] After the bottom of the support block 412 is supported on the inspection table, the base 42 needs to be reset by the hydraulic cylinder 152, so that the medical staff needs to release the limiting effect of the sliding block 63 on the panel 41. Since the end of the positioning column 61 is welded to the base 42 and the width of the base 42 is smaller than the width of the support block 412, the sliding block 63 slides toward the base 42. When limiting the panel 41, the sliding block 63 needs to slide toward the vertical section of the limiting block 62 first, which is not convenient for operation. Therefore, a limiting piece 65 is welded on the side wall of the positioning column 61. The limiting piece 65 is located between the base 42 and the sliding block 63, and the side wall of the limiting piece 65 facing the sliding block 63 is in the same plane as the side wall of the supporting block 412. When the sliding block 63 releases the limiting effect on the panel 41, the medical staff only needs to slide the sliding block 63 along the length direction of the panel 41, and the sliding block 63 cannot slide toward the base 42, so that the end of the sliding block 63 is separated from the supporting block 412, and then the hydraulic cylinder 52 is controlled to drive the base 42 to reset, so that the patient and the panel 41 are transferred to the testing table.

[0050] The implementation principle of this embodiment is as follows: when the patient needs to undergo a medical imaging scan, the bed body 1 is pushed to one side of the inspection table, and after the bed body 1 and the inspection table are aligned, the sliding block 63 is moved to limit the panel 41, and the panel 41 on which the patient lies is lifted by the hydraulic cylinder 2 431, and then the panel 41 is pushed toward the direction close to the inspection table by the hydraulic cylinder 1 52, and the position of the panel 41 on the inspection table is determined according to the laser ranging sensor 422, and the extension and contraction amount of the hydraulic cylinder 1 431 is controlled so that the patient can be located at the center of the inspection table for examination, and after the hydraulic cylinder 2 52 is reset, the bottom of the support block 412 is supported on the inspection table, and then the medical staff releases the limiting effect of the sliding block 63, and then controls the output end of the hydraulic cylinder 1 52 to contract, and the patient is transferred to the medical imaging scanning device. The process improves the efficiency of transferring patients during medical imaging examinations. After that, when the patient examination is completed, the hydraulic cylinder 431 is reset to put the hydraulic cylinder 431 in a retracted state. After ensuring that the roller 4323 is located below the panel 41, the hydraulic cylinder 52 is controlled to extend to push the base 42 to the bottom of the panel 41. The medical staff slides the sliding block 63 to limit the relative position between the panel 41 and the base 42, and then controls the hydraulic cylinder 431 to extend to make the bottom surface of the support block 412 higher than the bottom surface of the through groove 12. The hydraulic cylinder 52 is controlled to retract to drive the panel 41 to move toward the bed board 1. After the hydraulic cylinder 52 is retracted to the initial state, the hydraulic cylinder 431 is controlled to retract to reset the panel 41, thereby realizing the transfer of the patient from the examination table to the bed body 1, thereby increasing the multifunctionality of the system.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
