Description

Technical Field

[0001] The utility model relates to the technical field of medical detection equipment, in particular to a patient breath-holding detection device for abdominal MRI scanning. Background Art

[0002] Abdominal MRI is an MRI examination of the abdomen. It is superior to CT in detecting vascular invasion and tumor staging in the early stages of malignant tumors.

[0003] If the patient does not take a deep breath and hold his breath during the abdominal MRI scan, the patient's extremely subtle lesions may be easily missed by the CT scan. If the patient does not hold his breath well, artifacts may be generated during the MRI scan, resulting in unclear images, incomplete scans, and misdiagnosis.

[0004] When testing the patient's breath-holding, the breath-holding detection body is placed on the patient's belly to test whether the patient can hold his breath. During the test, the breath-holding detection body is tied to the belly with a connecting belt. However, after use, when the detection device is placed aside, the connecting belt is relatively messy and takes up space, reducing the use effect of the device.

[0005] Therefore, we propose a patient breath-holding detection device for abdominal MRI scanning to solve the above problems. Utility Model Content

[0028] The winding assembly 8 includes a first limit block 81 movably inserted in the inner cavity of the adjacent limit groove 10 and a supporting tray 82 fixedly installed at the bottom of the first limit block 81. A vertical rod 83 is fixedly installed at the bottom center of the supporting tray 82. The bottom end of the vertical rod 83 is rotatably connected to the bottom of the inner cavity of the fixed groove 3. A ratchet 84 is fixedly sleeved on the outer periphery of the vertical rod 83. A pawl 85 is engaged with the outer periphery of the ratchet 84 near one side. A movable rod 86 is hinged on one side of the pawl 85. A vertical plate 87 is hinged on one side of the movable rod 86. A cross bar 88 is fixedly installed on one side of the vertical plate 87. The cross bar 88 movably passes through one side of the inner cavity of the fixed groove 3 and is fixedly installed with a handle 89. By arranging a torsion spring 831, when the pawl 85 and the ratchet 84 are separated, the vertical rod 83 can be rotated to make the winding roller 5 rotate automatically, so as to reel up the connecting belt 6, thereby avoiding the connection belt 6 from being messy and occupying space when the device is not in use, thereby improving the aesthetics of the device.

[0029] A torsion spring 831 is movably sleeved near the bottom end of the outer periphery of the vertical rod 83 , and the vertical rod 83 can rotate automatically through the setting of the torsion spring 831 , and one end of the torsion spring 831 is fixedly connected to the vertical rod 83 , and the other end of the vertical rod 83 is fixedly connected to the bottom of the inner cavity of the fixing groove 3 .

[0030] A support rod 851 is fixedly installed at the bottom of the pawl 85 near the front side. The pawl 85 can be supported by providing the support rod 851, and the bottom end of the support rod 851 is fixedly connected to the bottom of the inner cavity of the fixing groove 3.

[0031] A return spring 881 is provided on the outer periphery of the cross bar 88 near one end. By providing the return spring 881, the pawl 85 and the ratchet 84 can be fitted with each other, thereby limiting the position of the ratchet 84, and the two ends of the return spring 881 are fixedly connected to the adjacent handle 89 and one side of the fixing groove 3 respectively.

[0032] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 2 — Figure 5The disassembly assembly 9 includes a telescopic rod 91 fixedly installed on the top of the inner cavity of the fixed groove 3 near both sides and a pressure plate 92 fixedly installed on the end of the telescopic rod 91. A second limit block 93 is fixedly installed at the center of the bottom circle of the pressure plate 92, and the second limit block 93 is movably inserted in the inner cavity of the adjacent limit groove 10. By setting a plurality of support rods 921, the pressure plate 92 can be moved upward, thereby squeezing the telescopic spring 911 and the telescopic rod 91, so that the second limit block 93 fixed on the pressure plate 92 can be moved away from the inner cavity of the adjacent limit groove 10, which is convenient for releasing the limit of the winding roller 5 and replacing the damaged winding roller 5.

[0033] A plurality of support rods 921 are fixedly installed on the periphery of the pressure plate 92, and telescopic springs 911 are movably sleeved on the periphery of the telescopic rods 91.

[0034] Working principle: When the utility model is used, firstly, the breath-hold detection body 1 is placed on the belly of the person to be detected, and the sub-buckle 7 fixed on the connecting belt 6 is movably inserted into the inner cavity of the female buckle 2 by pulling the connecting belt 6, and the breath-hold detection body 1 is worn on the belly of the person to be detected. When the patient breathes during the breath-holding process, the belly will float. With the cooperation of the pressure sensor 4, the value can be detected and displayed on the display screen of the breath-hold detection body 1. The working principle of the breath-hold detection body 1 has been disclosed in the breath-hold detection device for patients for CT scanning (CN211583198U). When the breath-hold detection body 1 is used, the handle 89 is used to pull the cross bar 88 to one side to move the forehead plate 87 fixed on the cross bar 88 to one side. By setting the movable rod 86, the pawl 85 can be separated from the ratchet 84, and under the action of the torsion spring 831, the vertical rod 83 can be rotated. With the cooperation of the supporting tray 82 and the first limit block 81, the winding roller 5 can be rotated, and then the connecting belt 6 can be wound, thereby avoiding the connection belt 6 from being messy and occupying space when the device is not in use, and improving the aesthetics of the device. When the winding roller 5 needs to be replaced, at this time, a number of support rods 921 can be set to move the pressure plate 92 upward, thereby squeezing the telescopic spring 911 and the telescopic rod 91, so that the second limit block 93 fixed on the pressure plate 92 can be moved away from the inner cavity of the adjacent limit groove 10, which is convenient for releasing the limit of the winding roller 5 and replacing the damaged winding roller 5.
