Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and more particularly to a patient position adjustment device based on magnetic resonance examination. Background Art

[0002] Brain perfusion imaging is mainly used to evaluate the blood perfusion of brain tissue, and its detection equipment is mainly magnetic resonance imaging (MRI). Existing magnetic resonance imaging (MRI) devices are not convenient for elderly patients with inflexible legs to get in and out of bed during use, and medical staff are required to assist during the detection process, which is inconvenient to use.

[0003] In response to the above problems, the prior art, such as a Chinese patent with authorization announcement number CN114041777B, discloses a brain perfusion imaging detection device based on magnetic resonance. The device includes a nuclear magnetic resonance imager on which a detection channel is provided. The bed is driven to rotate by a rotating mechanism so that the patient's body can completely enter the nuclear magnetic resonance imager for detection. After the detection is completed, the bed is driven by the driving mechanism to move in a direction away from the nuclear magnetic resonance imager so that the bed is gradually connected to the output end of the rotating mechanism by transmission. Subsequently, the bed is driven to rotate by the rotating mechanism so that the patient is in an upright state, making it easier for elderly patients with inflexible legs to get in and out of bed, and is convenient for elderly patients or patients with leg diseases to use.

[0004] However, when the detection device is actually used, it is unable to move the position of the patient lying on the bed according to the patient's height, which may easily lead to that the patient with shorter height cannot be detected conveniently and needs to adjust the body position back and forth, which is cumbersome to operate. In addition, the inner side wall of the detection channel of the detection device cannot be easily cleaned. If the inner side wall of the detection channel is attached with objects that are difficult to observe after or before the detection, the detection result will be inaccurate, resulting in misdiagnosis. Summary of the invention

[0005] In view of the problem that when the detection equipment existing in the prior art is in use, the inner side walls of the detection channel cannot be easily cleaned. If there are objects that are difficult to observe attached to the inner side walls of the detection channel after or before the detection, the detection result will be wrong, resulting in misdiagnosis. At the same time, the detection equipment cannot move the position of the patient lying on the bed according to the patient's height, which may easily lead to the problem that patients with shorter height cannot be conveniently detected. The purpose of the present invention is to provide a patient position adjustment device based on magnetic resonance imaging.

[0006] To solve the above problems, the present invention adopts the following technical solutions:

[0048] The lifting plate 13 is disposed above the lifting mechanism 3. The supporting board 10 is slidably connected to the top surface of the lifting plate 13. The lying board 8 is slidably connected to the top surface of the supporting board 10. The top surface of the supporting board 10 is in mutual contact with the bottom surface of the lying board 8, and the bottom surface of the supporting board 10 is in mutual contact with the top surface of the lifting plate 13.

[0049] When using the nuclear magnetic resonance imaging instrument 1, first use the lifting mechanism 3 to move the position of the lifting plate 13 to a position where the patient can use it conveniently. According to the height of the patient, use the adjustment mechanism 4 to move the position of the lying board 8 to adjust the position of the patient. Subsequently, use the pushing mechanism 5 to move the position of the supporting board 10 and enter the inside of the nuclear magnetic resonance imaging instrument 1 to facilitate the detection of the patient.

[0050] To facilitate the cleaning of the inside of the nuclear magnetic resonance imaging instrument 1, as Figure 2 and Figure 8 shown, the cleaning mechanism 2 includes a support frame 21 and a cleaning cotton 22. The bottom surface inside the nuclear magnetic resonance imaging instrument 1 is fixedly installed with a fixed seat 11. A T-shaped groove 16 is provided inside the top surface of the fixed seat 11. The cleaning cotton 22 is disposed inside the nuclear magnetic resonance imaging instrument 1. A moving plate 12 is fixedly installed inside the cleaning cotton 22. A T-shaped block 15 is fixedly installed on the bottom surface of the moving plate 12. The T-shaped block 15 is slidably connected to the inside of the T-shaped groove 16 through the moving plate 12. The outer side wall of the cleaning cotton 22 is in mutual contact with the inner side wall of the nuclear magnetic resonance imaging instrument 1. The moving plate 12 is disposed on the left side of the connecting mechanism 7.

[0051] When the cleaning mechanism 2 is in use and cleaning the inner side wall of the nuclear magnetic resonance imaging device 1, the moving plate 12 is moved, which can conveniently drive the cleaning cotton 22 to move, and can conveniently make the cleaning cotton 22 clean the inner side wall of the nuclear magnetic resonance imaging device 1, preventing impurities or iron particles from adhering to the inner side wall and causing misdiagnosis during subsequent use.

[0052] To facilitate the up and down adjustment of the position of the lying plate 8, as Figure 1 and Figure 2 shown, the lifting mechanism 3 includes a support base 31, fixed blocks 32, moving blocks 33, connecting rods 34, first reciprocating motors 35, moving grooves 36 and bidirectional screws 37. The support bases 31 are symmetrically and fixedly installed at the upper end of the bottom plate 9. The moving grooves 36 are respectively arranged inside the fixed blocks 32. The bidirectional screws 37 are respectively rotatably connected inside the moving grooves 36. The fixed blocks 32 are respectively symmetrically slidably connected inside the moving grooves 36 and are respectively threadedly sleeved at both ends of the bidirectional screws 37. The fixed blocks 32 are symmetrically and fixedly installed at the bottom surface of the lifting plate 13. One end of each connecting rod 34 is respectively hinged inside the side wall of the moving block 33, and the other end is hinged inside the side wall of the fixed block 32. The first reciprocating motors 35 are respectively fixedly connected to the right side wall of the support base 31. The output shafts of the first reciprocating motors 35 respectively pass through the side wall of the support base 31 and are fixedly connected to the right end of the bidirectional screw 37.

[0053] When the lifting mechanism 3 is in use, according to the state of the patient, the position of the lying plate 8 is adjusted. The first reciprocating motor 35 is turned on to rotate the bidirectional screw 37, which can conveniently drive the moving blocks 33 to move towards or away from each other, and can drive the lifting plate 13 to move up and down, so as to conveniently adjust the position of the lying plate 8 to a position where the patient can lie down conveniently, and then use the first reciprocating motor 35 to reset the position of the lying plate 8.

[0054] To facilitate the adjustment of the position of the patient after lying down, as Figure 1 and Figure 5As shown in the figure, the adjusting mechanism 4 includes a second reciprocating motor 41, a chute 42, a lead screw 43 and a slider 44. The second reciprocating motor 41 is fixedly installed on the right end side wall of the support plate 10. The chute 42 is arranged inside the top surface of the support plate 10. The lead screw 43 is rotatably connected inside the chute 42. The output shaft of the second reciprocating motor 41 is fixedly connected to the right end of the lead screw 43 through the side wall inside the support plate 10. The slider 44 is fixedly connected to the bottom surface of the lying plate 8. The slider 44 is slidably connected inside the chute 42 through the lying plate 8 and is threadedly sleeved on the rod wall of the lead screw 43. The inner side wall of the cleaning cotton 22 is made of plastic material, and the shape of the cleaning cotton 22 matches the size of the space inside the nuclear magnetic resonance imaging instrument 1. The bottom surface of the cleaning cotton 22 is mutually attached to the top surface of the fixed seat 11. The slider 44 is arranged at the right end of the lying plate 8, and the length of the slider 44 is less than the length of the lying plate 8 and less than the length of the chute 42. The length of the lying plate 8 is less than the length of the support plate 10.

[0055] When the adjusting mechanism 4 is in use, according to the height of the patient and the position where the patient lies down, the position of the patient is adjusted. The second reciprocating motor 41 is turned on to make the lead screw 43 rotate, which can conveniently drive the slider 44 to move, so that the lying plate 8 can move on the support plate 10 to adjust the position of the patient.

[0056] To facilitate the patient to enter the inside of the nuclear magnetic resonance imaging instrument 1, as Figure 1 and Figure 9 shown, the pushing mechanism 5 includes a cylinder 51, a first groove 52, a ball 53 and a second groove 54. An installation plate 14 is fixedly installed at the upper end of the lifting plate 13. The cylinders 51 are symmetrically fixedly installed on the side walls of the installation plate 14. The output shafts of the cylinders 51 are respectively fixedly connected to the side walls of the support plate 10 through the side walls inside the installation plate 14. The first grooves 52 are symmetrically arranged inside the top surface of the lifting plate 13. The second groove 54 is arranged inside the top surface of the fixed seat 11. The balls 53 are respectively rotatably connected at equal intervals inside both sides of the bottom surface of the support plate 10, and the balls 53 are slidably connected inside the first groove 52 through the support plate 10 and are slidably connected inside the second groove 54 through the inside of the first groove 52.

[0057] When pushing the patient into the inside of the nuclear magnetic resonance imaging instrument 1, the cylinder 51 is turned on to make it push the position of the support plate 10 to move. At this time, the top surface of the lifting plate 13 is horizontal with the top surface of the fixed seat 11, and the balls 53 can enter the second groove 54 through the inside of the first groove 52, which is convenient for the support plate 10 to enter the inside of the nuclear magnetic resonance imaging instrument 1 and convenient for detecting the patient.

[0058] To enable the lifting plate 13 to move stably, asFigure 1 and Figure 9 As shown in Figure 9 , the limit mechanism 6 includes support columns 61, limit grooves 62 and limit blocks 63. The support columns 61 are symmetrically and fixedly installed on both sides of the top surface of the bottom plate 9 respectively. The limit grooves 62 are respectively arranged inside the support columns 61. The limit blocks 63 are symmetrically and fixedly connected to the side walls at both ends of the lifting plate 13 respectively. The limit blocks 63 are respectively slidably connected to the inside of the limit grooves 62 through the lifting plate 13, and the width of the limit blocks 63 matches the width of the limit grooves 62.

[0059] When the limit mechanism 6 is in use, when the lifting plate 13 moves up and down, the limit blocks 63 on the lifting plate 13 are respectively slidably connected to the inside of the limit grooves 62, which can make the position of the lifting plate 13 stable during movement.

[0060] To facilitate the movement of the moving plate 12 to drive the cleaning cotton 22 to move, as shown in Figure 2 Figure 2 and Figure 10 As shown in Figure 10 , the connection mechanism 7 includes connection grooves 71, pins 72 and connection blocks 73. The connection grooves 71 are arranged inside the left side wall of the support plate 10. The connection blocks 73 are symmetrically arranged on the side walls at both ends of the moving plate 12 respectively. The pins 72 are respectively slidably connected to the inside of the connection blocks 73. When the support plate 10 enters the inside of the nuclear magnetic resonance imaging apparatus 1, the upper and lower side walls of the support plate 10 are respectively in contact with the bottom surface of the fixed seat 11 and the bottom surface of the connection block 73. The pins 72 are respectively slidably connected to the inside of the support plate 10 through the inside of the connection blocks 73. The width of the moving plate 12 matches the width of the connection grooves 71. The moving plate 12 is slidably connected to the inside of the connection grooves 71. The moving plate 12 is perpendicular to the top surface of the fixed seat 11.

[0061] When the connection mechanism 7 is in use, when the support plate 10 enters the inside of the nuclear magnetic resonance imaging apparatus 1, the bottom surface of the support plate 10 is in contact with the top surface of the fixed seat 11, and the top surface of the support plate 10 is in contact with the bottom surface of the connection block 73. And the moving plate 12 is clamped into the inside of the connection grooves 71. Then the pins 72 can be fixedly connected to the inside of the support plate 10 through the inside of the connection blocks 73, so as to be able to conveniently drive the moving plate 12 to move its position, and enable the cleaning cotton 22 to move to clean the inner side wall of the nuclear magnetic resonance imaging apparatus 1.

[0062] The working process of the technical solution provided by the present invention is as follows:

[0063] During use, according to the patient's condition, the position of the lying board 8 is adjusted. The first reciprocating motor 35 is turned on to rotate the bidirectional screw 37, which can conveniently drive the moving blocks 33 to move towards or away from each other, and can drive the lifting plate 13 to move up and down, so as to conveniently adjust the position of the lying board 8 to a position where it is convenient for the patient to lie down. When the lifting plate 13 moves up and down, the limit blocks 63 on the lifting plate 13 are respectively slidably connected to the inside of the limit grooves 62, which can make the position of the lifting plate 13 stable during movement. Then, the first reciprocating motor 35 is used to reset the position of the lying board 8. Subsequently, according to the patient's height and the position where the patient lies down, the position of the patient is adjusted. The second reciprocating motor 41 is turned on to rotate the lead screw 43, which can conveniently drive the slider 44 to move, so as to move the lying board 8 on the support plate 10 and adjust the position of the patient. When the patient is pushed into the inside of the nuclear magnetic resonance imaging instrument 1, the air cylinder 51 is turned on to push the support plate 10 to move. At this time, the top surface of the lifting plate 13 is level with the top surface of the fixed seat 11, and the ball 53 can enter the inside of the second groove 54 through the inside of the first groove 52, which is convenient for the support plate 10 to enter the inside of the nuclear magnetic resonance imaging instrument 1 for convenient detection of the patient.
