[0023] Device Example:

[0024] See also Figures 1 to 4 , which shows the preferred structure of the magnetic resonance scanning body position adjustment device provided by the embodiment of the utility model. As shown in the figure, the body position adjustment device includes: a flexible adjustment shoulder pad, a flexible adjustment neck pad, a flexible adjustment head pad and two flexible fixed pads; wherein,

[0025] The flexible shoulder pad is used to adjust the bottom flexible support height of the patient's shoulder below the patient's shoulder. Specifically, the flexible shoulder pad can be a flexible support structure, and the height of the flexible shoulder pad can be adjusted to support the patient's shoulder support height below the patient's shoulder.

[0026] The flexible adjustment neck pad is arranged on one side of the flexible adjustment shoulder pad (such as Figure 1 The flexible shoulder pad is a flexible support structure (shown on the lower left side) used to adjust the height of the bottom flexible support for the patient's neck below the patient's neck. Specifically, the flexible adjustable shoulder pad can be a flexible support structure, and the height of the flexible adjustable neck pad can be adjusted to provide support for the patient's neck below the patient's neck with adjustable height. The outer wall of the flexible adjustable neck pad is connected to the flexible adjustable shoulder pad, that is, the outer walls are mechanically connected, and the positions can be adjusted and installed together. At the same time, the height adjustments of the flexible adjustable shoulder pad and the flexible adjustable neck pad are independent of each other, and the corresponding heights can be adjusted relatively independently, and the two will not interfere with each other when adjusting the height. For example, the flexible adjustable neck pad is flush with the bottom wall of the flexible adjustable shoulder pad and is mechanically connected to each other, and the top is not connected, so that independent height adjustment of the top can be achieved.

[0027] The flexible adjustment head pad is arranged on the side of the flexible adjustment neck pad facing away from the flexible adjustment neck pad (such as Figure 1 The flexible adjustment shoulder pad is a flexible adjustment neck pad, and the flexible adjustment neck pad is a flexible adjustment head pad. The flexible adjustment shoulder pad is a flexible adjustment neck pad, and the flexible adjustment head pad is used to adjust the height of the bottom flexible support for the patient's head under the patient's head. Specifically, the flexible adjustment shoulder pad, the flexible adjustment neck pad, and the flexible adjustment head pad are arranged in sequence along a straight line, and the bottom walls of the three are flush and the outer walls are mechanically connected. Among them, the flexible adjustment head pad can be a flexible support structure, and the height of the flexible adjustment head pad can be adjusted to provide support with adjustable height of the patient's head under the patient's head. At the same time, the height adjustments of the flexible adjustment head pad and the flexible adjustment neck pad are independent of each other, and the corresponding heights can be adjusted relatively independently, and the two will not interfere with each other when adjusting the height.

[0028] The two flexible fixing pads are respectively arranged at the two ends of the flexible adjustment head pad, and the outer walls of the two flexible fixing pads are respectively connected to the two ends of the flexible adjustment head pad, so as to adjust the thickness of the flexible limit on both sides of the patient's head to achieve the fixed limit of the patient's head. Specifically, the two flexible fixing pads can be respectively arranged at an angle at the two ends of the flexible adjustment head pad (such as Figure 1 The left and right ends shown in the figure) can clamp the patient's head on both sides of the patient's head. In particular, the thickness of the flexible fixing pad can be adjusted so that it can be adaptively adjusted according to the position and width of the patient's head, thereby achieving flexible clamping of heads of different sizes.

[0029] In this embodiment, the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad can all be airbag structures, i.e., air cushions, so as to realize flexible support and thickness adjustment of the airbag structure by inflation and deflation of the airbag structure. Specifically, an air cavity may be provided inside the airbag structure, which is used to expand or contract the airbag structure by inflation and deflation, so as to adjust the thickness of the air cushion, and then adjust the height position of the corresponding position of the patient, so as to realize body position adjustment and position adjustment. In this embodiment, the air cavities of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the two flexible fixed pads are independent of each other, i.e., not connected to each other, so as to independently control the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and each of the flexible fixed pads, so as to independently inflate and deflate the air, so as to adjust the thickness of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and each of the flexible fixed pads, so as to realize body position adjustment and corresponding position adjustment. Of course, the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad may also be other flexible support structures capable of adjusting the support thickness, and no limitation is made to them in this embodiment.

[0030] Of course, in other embodiments, the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad may also be flexibly supported and thickness adjusted in other ways, which is not limited in this embodiment.

[0031] Continue to see Figure 1 , the air cavities of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad are connected with charging and discharging air pipes. Specifically, the air cavities of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad can be connected with charging and discharging air pipes, so as to inflate and deflate the air in the air cavities through the charging and discharging air pipes to adjust the support thickness. Preferably, the charging and discharging air pipes can be connected with an inflation mechanism and a control valve, and in particular, the control valve can be arranged between the inflation mechanism and the charging and discharging air pipes to control the on and off of the charging and discharging air pipes to control the independent expansion and contraction of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad to adjust the height or thickness. That is to say, the independent inflation and deflation of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad can be controlled by controlling the control valve and the inflation mechanism, thereby realizing the individual adjustment function of each airbag. In this embodiment, the inflation and deflation tube can be made of flexible non-magnetic material, and is used to connect the inflation mechanism, the control valve and the airbag structure to realize the inflation and deflation function of the airbag structure; the inflation mechanism can generate high-pressure gas to provide a high-pressure gas source for the airbag structure.

[0032] Continue to see Figure 1 , the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad are all connected with a pressure sensor for obtaining the pressure data inside the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad. Specifically, in the present embodiment, the inflation and deflation air pipes connected to the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad are all provided with a pressure sensor for obtaining the pressure data inside the inflation and deflation air pipes connected to the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad, thereby obtaining the pressure data inside the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and the flexible fixed pad, i.e., the airbag pressure, and the height of each airbag can be determined based on the pressure data. Of course, pressure sensors can also be provided on some of the inflation and deflation air pipes, and other corresponding airbags can be controlled by other means.

[0033] In this embodiment, the pressure sensor may be connected to a controller, which is used to control the corresponding flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad according to the pressure data, so as to control the flexible support height of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad. Specifically, the controller may be connected to the inflation mechanism and the control valve respectively, and is used to control the inflation mechanism and the control valve based on the acquired pressure data and the flexible support height, i.e., the airbag height, so as to control the inflation and deflation of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad or the flexible fixed pad, thereby controlling the flexible support height of the flexible adjustable shoulder pad, the flexible adjustable neck pad, the flexible adjustable head pad and / or the flexible fixed pad. For example, when the airbag structure is inflated, the controller can control the inflation mechanism to automatically power on for inflation, that is, the inflation mechanism can automatically power on for inflation under the control of the controller, and control the control valve to be adjusted to an open state, so that the corresponding inflation and deflation pipe is in a connected state, thereby realizing the inflation of the airbag structure. In this embodiment, after the flexible adjustable shoulder pad, the flexible adjustable neck pad, and the flexible adjustable head pad are adjusted into place, the controller can control the flexible fixed pad to inflate and deflate, especially to inflate, so as to clamp both sides of the head adjusted into place, thereby achieving limited fixation on both sides of the head.

[0034] In this embodiment, the controller can also be connected to the scanning mechanism of the magnetic resonance scanning system, and is used to determine the position deviation between the patient's lesion site and the center of the magnet according to the patient's lesion position obtained by the scanning mechanism, and based on the position deviation, the flexible support height of the flexible adjustment shoulder pad, the flexible adjustment neck pad, the flexible adjustment head pad and / or the flexible fixed pad is controlled to position the patient's lesion to the center of the magnet. Specifically, the controller is connected to the scanning mechanism of the magnetic resonance scanning system, and the scanning mechanism scans the patient and automatically determines the position error of the patient's positioning, that is, the position deviation between the patient's lesion site and the center of the magnet, or the deviation between the patient's scanning site, that is, the lesion site and the center of the receiving coil in the vertical direction, and calculates the error height, and then the controller adjusts the patient's position by adjusting the inflation and deflation of each airbag structure, so as to position the patient's scanning site to the center of the magnet, thereby adjusting the position of the patient's scanning site. In this embodiment, the position of the patient's lesion can be adjusted by positioning through the image scanning of the scanning mechanism, that is, the position of the patient's lesion can also be adjusted by positioning through image scanning. First, the patient is pushed into the center of the magnet, and the patient's lesion is scanned through the positioning sequence. After the positioning image is obtained, the deviation distance between the patient's lesion and the vertical direction of the magnetic field can be accurately measured, and then the air cushion is inflated and deflated through the control valve to adjust the patient's position. This method of positioning and adjusting through images can achieve accurate positioning of the lesion.

[0035] In this embodiment, the outer periphery of the flexible adjustment head pad and the flexible fixed pad may also be provided with a receiving coil for detecting the deviation of the center position of the patient's scanning part and the receiving coil in the vertical direction according to the internal photoelectric sensor. Specifically, the receiving coil is arranged on the outer periphery of the flexible adjustment head pad and the flexible fixed pad, so as to be arranged on the outer periphery of the patient's head, and the deviation of the center position of the patient's scanning part and the receiving coil in the vertical direction may be detected according to the internal photoelectric sensor. The receiving coil is connected with a controller for controlling the corresponding flexible adjustment shoulder pad, the flexible adjustment neck pad, the flexible adjustment head pad and / or the flexible fixed pad according to the deviation of the center position of the patient's scanning part and the receiving coil in the vertical direction to adjust the position deviation. The position error of the patient's positioning can be determined by the receiving coil worn by the patient, for example, the photoelectric sensor inside the receiving coil can detect the deviation of the center position of the patient's scanning part and the receiving coil in the vertical direction, and the corresponding airbag structure is inflated and deflated by the controller according to the position deviation, and the flexible support height is adjusted to adjust the patient's lesion to the center position of the magnet.

[0036] In addition, the flexible fixing pads on both sides of the patient's head can fix the patient's head inside the receiving coil. After the patient's lesion is accurately located, the control valve will inflate the flexible fixing pads on both sides of the head to clamp the patient's head inside the receiving coil to prevent motion artifacts and interference caused by the patient's movement during scanning, thereby improving the scanning imaging quality.

[0037] Adjustment of the patient's position in the center of the magnetic field: Figure 2As shown, when performing a flat scan of the lesion site, first, the patient is placed on the bed board so that the shoulders, neck, and head are placed on the shoulder pad, neck pad, and head pad of the device, and the patient is placed on the receiving coil for positioning, and then the patient is pushed to the center of the magnet. The initial height of each airbag structure is preset in the scanning sequence for different parts in the scanning mechanism, and the airbag structure will automatically adjust to the corresponding initial height when the corresponding sequence is selected. Then, the photoelectric sensor inside the receiving coil can detect the deviation between the patient's scanning part and the center position of the receiving coil in the vertical direction, and then the corresponding air cushion, especially the head cushion, is controlled by the control valve to inflate and deflate, so as to adjust the patient's lesion site to the center of the magnetic field; the patient's lesion position adjustment can also be positioned and adjusted by image scanning, first, the patient is pushed into the center of the magnet, and the patient's lesion site is scanned by the positioning sequence. After the positioning image is obtained, the deviation distance between the patient's lesion site and the vertical direction of the magnetic field can be accurately measured, and the air cushion is inflated and deflated by the control valve to adjust the patient's position. Finally, the flexible fixing pads on both sides of the patient's head can fix the patient's head inside the receiving coil. After the patient's lesion site is accurately located, the control valve will inflate the flexible fixing pads on both sides of the head to clamp the patient's head inside the receiving coil. After the adjustment is completed, subsequent detection scans can be performed for imaging diagnosis.

[0038] Patient position adjustment: Figure 3 As shown, when scanning the patient's neck in the supine position, that is, scanning in the flexed position, the patient needs to lie flat with his head tilted back as far as possible for scanning. At this time, the control valve needs to be used to adjust the air cushions to achieve the patient's supine position; in particular, the control valve is used to inflate the shoulder pad and neck pad and at the same time deflate the head pad to lower the head position, so that the patient can lie flat naturally to reach the supine position; after adjusting the body position, the control valve is locked, and the patient can remain in this position; the inflation and deflation can be determined according to actual conditions, and the corresponding position can also be located according to the scanning of the scanning mechanism, and the deviation distance between the patient's lesion site and the vertical direction of the magnetic field can be measured, and the scanning site can be adjusted to reach the center of the magnet. As shown Figure 4 As shown, when performing a head-down scan, the shoulder pad and the neck pad are deflated through the control valve, and the head pad is inflated to raise the patient's head position, so that the patient can lie down naturally to achieve a head-down position. After adjusting the body position, the control valve is locked to keep the patient in this position. The inflation and deflation can be determined according to actual conditions, and the corresponding position can also be located according to the scanning of the scanning mechanism, and the deviation distance of the patient's lesion site from the vertical direction of the magnetic field can be measured, and the scanning site can be adjusted to reach the center of the magnet.

[0039] In summary, the magnetic resonance scanning position adjustment device provided in this embodiment can adjust the bottom flexible support height of the patient's shoulder under the patient's shoulder by adjusting the thickness of the flexible adjustable shoulder pad; the bottom flexible support height of the patient's neck can be adjusted under the patient's neck by adjusting the thickness of the flexible adjustable neck pad; the bottom flexible support height of the patient's head can be adjusted under the patient's head by adjusting the thickness of the flexible adjustable head pad, so that the patient's scanning part can be accurately placed in the vertical center position of the magnetic field when positioning the patient, thereby obtaining high-quality diagnostic images, and the patient's scanning position can be automatically adjusted according to the patient's examination needs, so as to more accurately scan and image the patient's lesions, thereby improving the accuracy of the doctor's diagnosis of the patient's condition; by adjusting the thickness of the two flexible fixed pads, the thickness of the flexible limit on both sides of the patient's head can be adjusted on both sides of the patient's head to achieve fixed limit of the patient's head, so that the patient can continuously and stably maintain the same position or scanning position, prevent the patient from maintaining position fatigue during the scanning process, reduce the possibility of patient movement during the scanning process, and improve the scanning image quality and speed.
