Description

Technical Field

[0001] The present invention relates to the technical field of medical imaging equipment, and in particular to a calibrator for medical imaging equipment. Background Art

[0002] When certain lesions occur in a part of the patient's body, the temperature of the tissue will also change. Therefore, an infrared scanner is used to scan and detect the temperature of the patient's body, and then compare it with the normal temperature data of each part to find the location of the patient's lesion, and then further examination is carried out to achieve the purpose of body examination.

[0003] Most of the common medical infrared scanners on the market currently are equipped with an upright support pole, and then the infrared sensing probe is installed on the outer surface of the support pole. The infrared sensing probe can slide up and down and can also rotate at pitch and horizontal angles, so that doctors can make detailed observations of specific parts during examinations. This process requires the control component (operated by the doctor) and the drive component (installed on the infrared sensing probe) to cooperate. However, in actual use, as time passes and the device is not maintained, errors may occur in the actual moving distance and rotation angle of the drive component. For example, if you want to push up ten centimeters through the control component, the actual output of the drive component is only 9 centimeters upward, or there are problems such as the wrong direction or abnormal moving speed during the movement process. At this time, it needs to be inspected and maintained. However, how to judge whether the fault has been repaired during the inspection? Some subtle movement errors are difficult to judge visually with the naked eye. For this reason, a calibrator for medical imaging equipment is specially provided to solve the above problems.

[0018] The present invention discloses a calibrator for medical imaging equipment, which has the following beneficial effects:

[0019] 1. The calibrator for medical imaging equipment adjusts the distance between the screen and the infrared camera by pressing the L-shaped movable plate downward and pulling the telescopic support arm outward. The locking handle is then loosened counterclockwise and the adjustment handle is then turned counterclockwise to slide the slider outward, ultimately making the screen perpendicular to the infrared camera. The suction cup is attached to the top of the infrared camera and the laser pointer is rotated so that the orientation of the laser pointer and the infrared camera are consistent. The infrared camera is then controlled to move up and down, and the laser pointer's laser is irradiated on the outer surface of the screen. The movement distance is then calculated based on the scale lines and compared with the control unit's panel data to determine whether there is any movement error. The infrared camera is also controlled to rotate in pitch and horizontal angles. Based on the movement distance of the laser pointer's laser on the screen, since the laser pointer and the infrared camera are perpendicular to the screen, the Pythagorean theorem can be used to calculate the rotation angle of the infrared camera. The calculation is then compared with the control unit's panel data to determine whether there is any rotation angle error, thereby achieving calibration of the infrared camera.

[0020] 2. The calibrator for medical imaging equipment pulls the two sets of splints outward so that the two sets of splints move along the opposite ends of the connecting axis. At this time, the curtain on the outer surface of the roller is released outward, and the coil spring inside it is tightened and locks the two sets of splints to move. The opposite ends of the two sets of support bars move away from each other, so that the support bars are stretched to a horizontal state. At this time, the rotating shaft at the end of the support bar rotates. When the support bar is completely horizontal, the card hole on the outer surface of the rotating shaft is opposite to the pin. At this time, under the action of the locking spring, the sliding shaft moves upward, so that the pin is inserted into the card hole for fixation, so that the two sets of splints remain in an open state for easy use.

[0021] 3. The calibrator for medical imaging equipment presses the two sets of dial blocks toward the middle to retract the sliding rod into the inside of the baffle, and then pulls the baffle backward to simultaneously remove the pressure plate, and then buckles the fixing frame on the front outer surface of the medical infrared scanner, and then installs the pressure plate from the back to the inside of the limit slot, and releases the dial blocks. Under the action of the reset spring, the sliding rod is inserted into the inside of the fixing frame for fixation, and then the position is adjusted by moving the fixing frame up and down along the medical infrared scanner, and then the locking screw is turned clockwise to move the U-shaped frame inward on the outer surface of the locking screw, so that the pressure plate is tightly attached to the back of the medical infrared scanner for fixation, so that the entire calibration test mechanism is installed on the front side of the medical infrared scanner.

[0040] A plurality of card slots 54 are provided at the inner top of the support sleeve 51, an L-shaped movable plate 55 is provided inside the telescopic support arm 52, a memory spring 56 is provided at the bottom of the L-shaped movable plate 55, the front end of the L-shaped movable plate 55 extends to the top of the support sleeve 51, and a card strip 57 is provided at the top of the end of the L-shaped movable plate 55, and the card strip 57 is movably connected to the inside of the card slot 54.

[0041] The mounting mechanism 7 includes a fixing frame 71 which is sleeved on the outer surface of the medical infrared scanner 1. A group of detachable baffles 74 are movably connected to the back of the fixing frame 71. A U-shaped frame 76 is movably inserted into the interior of the baffle 74. The front end of the U-shaped frame 76 is fixedly connected to a pressure plate 72. The pressure plate 72 is pressed onto the back of the medical infrared scanner 1. The outer surface of the baffle 74 is rotatably connected to a locking screw 75. The U-shaped frame 76 is threadedly connected to the outer surface of the locking screw 75.

[0042] The two groups of fixing frames 71 are fixedly connected to the supporting sleeve 51 and the fixing tube 61 respectively. A limiting groove 73 is provided on the back of the fixing frame 71. Positioning blocks 77 are integrally formed at both ends of the pressure plate 72. The positioning blocks 77 are movably inserted into the inside of the limiting groove 73. Sliding rods 78 are provided inside both ends of the baffle 74. Return springs 710 are provided on the opposite side of the bottom ends of the two groups of sliding rods 78. A shift block 79 is provided on the opposite side of the top ends of the two groups of sliding rods 78. The opposite ends of the two groups of sliding rods 78 are respectively inserted into the inside of the two ends of the fixing frame 71.

[0043] When the locking nut 75 is in the unlock state, the locking nut 75 is unlocked, and the locking nut 75 is unlocked, so that the locking nut 75 is unlocked and the locking nut 75 is unlocked.

[0044] Then, by pulling the two groups of clamping plates 23 outward, the two groups of clamping plates 23 move toward opposite ends along the connecting shaft 26. At this time, the curtain 21 on the outer surface of the roller 25 is released outward, and the coil spring inside it is tightened, locking the two groups of clamping plates 23 to move. The opposite ends of the two groups of support bars 27 move away from each other, so that the support bars 27 are stretched to a horizontal state. At this time, the rotating shaft 28 at the end of the support bar 27 rotates. When the support bar 27 is completely horizontal, the locking hole on the outer surface of the rotating shaft 28 is opposite to the latch 243. At this time, under the action of the locking spring 242, the sliding shaft 241 moves upward, so that the latch 243 is inserted into the inside of the locking hole to fix it, so that the two groups of clamping plates 23 remain in the open state.

[0045] Then, the L-shaped movable plate 55 is pressed downward to compress the memory spring 56. At this time, the card strip 57 is disengaged from the card slot 54. Then, the telescopic support arm 52 is pulled outward to adjust the distance between the screen 21 and the infrared camera. Then, the L-shaped movable plate 55 is released. Under the action of the memory spring 56, the card strip 57 is inserted into the card slot 54 to be fixed. Then, by loosening the locking handle 69 counterclockwise and then turning the adjustment handle 67 counterclockwise, the adjustment gear 65 is rotated. At this time, the adjustment gear 65 is meshed with the tooth groove 63 for transmission, causing the sliding bar 62 to slide outward, and finally the screen 21 is perpendicular to the infrared camera.

[0046] Then, by adsorbing the suction cup 4 on the top of the infrared camera and rotating the laser pen 3, the orientation of the laser pen 3 and the infrared camera are kept consistent. At this time, the infrared camera is controlled to move up and down, and the laser of the laser pen 3 is irradiated on the outer surface of the screen 21. The moving distance is then calculated based on the scale line 22 and compared with the panel data of the control component to understand whether there is a movement error. At the same time, the infrared camera is controlled to rotate the pitch angle and the horizontal angle. At this time, based on the moving distance of the laser of the laser pen 3 irradiated on the screen 21, since the laser pen 3 and the infrared camera are perpendicular to the screen 21, the rotation angle of the infrared camera can be calculated by the Pythagorean theorem. Then, it is compared with the panel data of the control component to understand whether there is an error in the rotation angle, thereby achieving the calibration of the infrared camera.
