Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a pulse magnetic field measurement method and device. Background Art
[0002] When the magnetic field, especially the pulse magnetic field, acts on the human body, the flow of iron in the blood is accelerated and arranged in order, thereby achieving the effects of promoting blood circulation and removing blood stasis, promoting fluid return, relieving pain, promoting wound healing, improving sleep quality, promoting fracture healing and regulating the endocrine system.
[0003] The pulsed magnetic field therapy device outputs a pulsed magnetic field, which has been widely used as a magnetic therapy device. At the same time, the measuring instruments for testing the pulsed magnetic field therapy device are also valued. There are many instruments that can measure the magnetic field strength, but these instruments have a slow response speed and can only measure the relative static magnetic field, but cannot measure the strength of the pulsed magnetic field, and are even less competent for the width and period of the pulsed magnetic field. Although some foreign instruments such as the American FWBELL Bell 8030 Gauss meter can measure the strength of the pulsed magnetic field, they still need to be connected to an oscilloscope to measure the width and period of the pulsed magnetic field. Moreover, these instruments are expensive, which brings great inconvenience to people in monitoring whether the pulsed magnetic field therapy device is normal.
[0004] When using the existing pulse magnetic field measuring device, the operator needs to hold the oscilloscope probe and contact the pin H1 on the surface of the PCB board, then output the pulse magnetic field, and convert the magnetic field strength into a linear output electrical signal through the linear Hall sensor. Then, the electrical signal is converted into a visible image through the oscilloscope, and the image is displayed on the oscilloscope screen, thereby realizing the measurement of the pulse magnetic field.
[0005] The existing pulse magnetic field measurement device has some shortcomings in the measurement process. Since the operator needs to hold the oscilloscope probe, when the oscilloscope probe is in contact with the pin header H1 on the surface of the PCB board, the operator's hand is easily offset during the long-term holding of the oscilloscope probe by the operator, causing the oscilloscope probe to be unable to continuously contact the pin header H1 on the surface of the PCB board, which easily leads to disconnection of the electrical signal, thereby affecting the operator's measurement effect of the pulse magnetic field.

At this time, the operator can hold the oscilloscope probe 313 to move the connecting plate 315 at the bottom of the probe connecting column 314, and then press the extrusion block 3113 to compress the spring 1 3112 and move the limit column 3114, and then move the limit block 3113 on the side wall of the connecting plate 315. 16 is sleeved on the outer wall of the fixing column 317, so that the bottom of the contact head 318 contacts the top of the pin row 319, and then, by releasing the extrusion block 3113, the limit column 3114 is reset under the reaction of the spring 1 3112, prompting the limit column 3114 to insert into the side inner wall of the limit block 316, so as to limit the limit block 316, so that the position of the contact head 318 and the pin row 319 can be fixed, the stability of the oscilloscope probe 313 is improved, and the stability of the device in the measurement process of the pulse magnetic field is improved. After the position of the oscilloscope probe 313 is fixed, In order to prevent the oscilloscope probe 313 from swinging, it is also necessary to support the outer wall of the oscilloscope probe 313, so as to prevent the oscilloscope probe 313 from swinging. At this time, the operator can rotate the arc block 1 3125 and the arc block 2 3129, and fit the inner walls of the arc block 1 3125 and the arc block 2 3129 with the outer wall of the oscilloscope probe 313, so as to make the closing block 1 3127 fit with the closing block 2 3128, and then fit the threaded sleeve 3131 to the side wall of the closing block 1 3127, and then insert the stud 3130 into the inner wall of the closing block 2 3128, and rotate the arc block 1 3125 and the arc block 2 3129 to fit the inner wall of the closing block 2 3128. The stud 3130 limits the closing block 1 3127 and the closing block 2 3128 through the threaded sleeve 3131, thereby fixing the positions of the arc block 1 3125 and the arc block 2 3129. The other ends of the arc block 1 3125 and the arc block 2 3129 are movably connected to the top of the slider 3122 through a hinge, and the slider 3122 is sleeved on the outer wall of the cross bar 3121. The side wall of the slider 3122 is connected to the spring 2 3123, so that the oscilloscope probe 313 can be supported by two movable plates 3124, thereby improving the stability of the oscilloscope probe 313.
[0054] In the process of measuring the pulse magnetic field, in order to prevent the oscilloscope 311 from deviating during operation, the oscilloscope 311 needs to be clamped and fixed. At this time, the operator can turn on the double-headed motor 322 to cause the screw rod 323 to rotate. During the rotation of the screw rod 323, the sleeve block 324 will move, causing the clamping plate 325 to move. After the clamping plate 325 moves and fits with the outer wall of the oscilloscope 311, the clamping force of the clamping plates 325 on both sides of the oscilloscope 311 can be used to clamp and fix the oscilloscope 311, thereby preventing the oscilloscope 311 from deviating during operation.
