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.

When the lifting plate 13 moves up and down, the limit blocks 63 on the lifting plate 13 are slidably connected to the inside of the limit grooves 62, respectively, so that the position of the lifting plate 13 is stable when moving. 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, and the screw rod 43 is rotated, which can conveniently drive the slider 44 to move, so that the lying board 8 can move on the support plate 10. The position of the patient is adjusted, and the patient's position is adjusted. When entering the interior of the nuclear magnetic resonance imager 1, the cylinder 51 is opened to push the position of the support plate 10 to move, and at this time the top surface of the lifting plate 13 is level with the top surface of the fixing seat 11, and the ball 53 can pass through the interior of the first groove 52 to enter the interior of the second groove 54, so that the support plate 10 can enter the interior of the nuclear magnetic resonance imager 1, so as to facilitate the detection of the patient. When the support plate 10 enters the interior of the nuclear magnetic resonance imager 1, the bottom surface of the support plate 10 is fitted with the top surface of the fixing seat 11, and the top surface of the support plate 10 is fitted with the bottom surface of the connecting block 73, and the movable plate 12 is inserted into the interior of the connecting groove 71, and then the latch 72 can be fixedly connected to the interior of the support plate 10 by passing through the interior of the connecting block 73, so that the movable plate 12 can be conveniently driven to move the position, and the cleaning cotton 22 can be moved, so as to facilitate the cleaning of the inner side wall of the nuclear magnetic resonance imager 1 while detecting the patient.

[0064] The above is only a preferred embodiment of the present invention.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
