In use of the magnetic resonance imaging apparatus of the present invention, a patient is located on a transporter 300, a medical staff uses the transporter 300 to transport the patient into an examination room (the transporter 300 has universal wheels), then the transporter 300 is docked with the scanner bed 200, the medical staff can push the transporter 300 so that the docking head 303 of the transporter 300 is inserted into the docking seam, two docking heads 303 can be simultaneously inserted, or one docking head 303 can be inserted first, if two docking heads 303 are simultaneously inserted, more than the transporter 300 and the scanner bed 200 can be required to be aligned relatively, and the freedom of operation is necessarily limited by the alignment, so the docking head 303 on the right side of the transporter 300 can be inserted into the docking seam in the state of fig. 2.
The butt joint 303 pushes a group of movable plates 204 to prop open, two tension springs 205 of the group of movable plates 204 extend to enlarge a gap between the two movable plates 204, and when the arc protrusions of the butt joint 303 pass through the gap of the group of movable plates 204, the two tension springs 205 reset, and the gap between the group of movable plates 204 is reduced to prevent the butt joint 303 from falling off. To facilitate insertion of the butt joint 303 into the gap between the two movable plates 204, both ends of the movable plates 204 are provided with rounded structures.
After the butt joint 303 is inserted into the butt joint, the butt joint can enter a gap between two adjacent sleeves of the chain 203, an operator starts a driving motor, so that the chain wheel 202 and the chain 203 start to drive, because the butt joint 303 is inserted into the gap of the chain 203 and moves along with the chain 203, the transfer vehicle 300 can swing gradually to the state of fig. 1 in the process of moving the chain 203 because the butt joint 303 is inserted into the gap of the adjacent sleeve of the chain 203, and the joint on the left side of the transfer vehicle 300 also enters the butt joint and cannot fall off.
In this process, since the butt joint 303 is inserted into the gap of the adjacent movable plate 204, the movement of the transfer trolley 300 drives the mounting belt 207 where the movable plate 204 is located to move together, and the mounting belt 207 is unreeled.
After the transfer trolley 300 is aligned, the transfer trolley 300 gradually moves to the right, when the transfer trolley 300 moves to the butt joint 303 to trigger a limiting structure, the transfer trolley 300 and the scanning bed 200 are aligned, the driving motor of the driving structure is controlled by the limiting structure to stop rotating, and the butt joint is completed. And then, medical staff starts a motor on the transfer trolley 300 to enable the bearing plate 302 to move towards the bed body 201, and the bearing plate 302 and the bed body 201 are provided with mutually matched guide rails, so that when the bearing plate 302 and the bed body 201 are completely spliced, the position of the scanning bed 200 relative to the magnetic resonance imaging device is regulated and controlled, and the bed body 201 and the bearing plate 302 can be synchronously fed into the magnetic resonance imaging device 100 for detection imaging. It should be further noted that, a locking structure is disposed between the bed body 201 of the scanning bed 200 and the bearing plate 302 of the transfer vehicle 300, and after the bed body 201 and the bearing plate 302 are combined, they can be locked, so as to prevent the bed body 201 and the bearing plate 302 from moving relative to each other during the inspection process, and the locking structure may be a spring pin or other structure capable of realizing locking.
After the detection is completed, the bed body 201 and the bearing plate 302 exit the magnetic resonance imaging instrument 100, the bearing plate 302 returns to the vehicle body 301, the transfer vehicle 300 is pulled back, the connector can be separated from the gap of the movable plate 204, the winding mechanism is started to wind the mounting belt 207, all the movable plates 204 are reset, and the detection of the next patient can be performed.
In other embodiments, unlike the above embodiments, the chain transmission structure in the docking mechanism may be replaced with a belt transmission structure, and it can be understood that the belt transmission structure includes two pulleys and a belt, the pulleys can be rotatably disposed on the base 209 of the scanner bed 200 around the vertical axis, and the belt is wound around the two pulleys, one of the pulleys is connected with a driving motor, and then can be rotated under the driving of the driving motor.
That is to say, the transmission structure is a belt transmission structure, the connection structure comprises a plurality of movable plates 204, the plurality of movable plates 204 are arranged side by side and encircle a circle on the conveyor belt, the movable plates 204 are in a group, one end, far away from each other, of each movable plate 204 in the same group is rotationally connected with the conveyor belt of the belt transmission mechanism, elastic pieces are connected between all the movable plates 204 and the conveyor belt, and the initial elastic pieces promote the two movable plates 204 in the same group to be in a closed state; the butt joint 303 is provided with an arc protrusion, when in use, the butt joint 303 is inserted into the movable plate 204 from any position of the butt joint, and under the drive of the conveyor belt and the movable plate 204, the butt joint 303 drives the transfer trolley 300 to move to be aligned with the scanning bed 200, and the conveyor belt stops rotating to finish butt joint. After the inspection is completed, the transfer vehicle 300 is withdrawn, and the movable plate 204 does not need to be reset because the movable plate 204 moves along with the conveyor belt in a ring shape.
In a further embodiment, the limit structure is a travel switch, and when the docking head 303 touches the limit switch, the drive motor of the transmission structure is triggered to stop rotating, so as to complete docking.
In other embodiments, the limiting structure may be a damper 208, where the damper 208 is configured to be compressed to a preset position, and when the damper 208 is touched by the docking head 303, the scanning bed 200 is aligned with the transfer vehicle 300, and as the transmission structure continues to rotate, the docking head 303 continues to move and compress the damper 208, and when the position of the damper 208 reaches a specified position, the driving motor of the transmission structure is triggered to stop rotating to complete docking, and the limiting structure is set as the damper 208, so that a certain damping and buffering effect can be achieved, the impact caused by the alignment of the scanning bed and the transfer vehicle 300 is prevented, and the impact caused by the stop of the transfer vehicle is reduced, so that the patient feels comfortable as much as possible.
In a further embodiment, when the limiting structure is the damper 208, the driving motor that drives the driving structure to operate is an stepless speed regulating motor, after the butt joint 303 touches the damper 208, the load gradually increases along with the compression of the damper 208, so that the rotation speed of the driving motor can be properly reduced, and further, the moving speed of the scanning bed 200 can be reduced when the scanning bed 200 and the transfer trolley 300 are aligned, the impact caused by scram is reduced, and the influence on a patient is further reduced.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
