Example two
As shown in fig. 7, a first comparative example, in which another embodiment of the present invention is: a brake pad 23 is connected to the inside of the limiting shell 8 in a sliding manner, an adjusting rod 22 is fixed to one side, away from the rotating ball 9, of the brake pad 23, the adjusting rod 22 is connected with the limiting shell 8 through threads, and a plurality of rubber particles are fixed to one side, close to the rotating ball 9, of the brake pad 23; during operation, after the position of spacing casing 8 has been adjusted, medical personnel can manually rotate adjusting rod 22 and promote brake block 23 and slide in spacing casing 8, until brake block 23 and rolling ball 9 contact, thereby spacing rolling ball 9, prevent that rolling ball 9 from appearing the condition of rocking in follow-up nuclear magnetic resonance's in-process, and the frictional force between increase brake block 23 that rubber granule's setting can be further and rolling ball 9 improves the braking effect.
The working principle is as follows: when a patient needs to carry out nuclear magnetic resonance diagnosis, the patient is required to firstly confirm that the carried object on the patient body and the metal influenced by magnetic force do not exist in the patient body, so that the patient is prevented from being damaged in the nuclear magnetic resonance process, the patient lies on the moving bed 1 after the confirmation is correct, then the medical staff pushes the moving bed 1 to move the patient to the inside of the detection shell 2, before the patient needs to place a coil to be used on the placing frame 12 by the medical staff, after the position adjustment of the moving bed 1 is completed, the medical staff can manually rotate the adjusting sleeve 7, and as the adjusting sleeve 7 is in threaded connection with the lifting screw 6, the lifting screw 6 can slide in the hollow column 5 after the adjusting sleeve 7 rotates, at the moment, the lifting screw 6 slides downwards to drive the placing frame 12 to move towards the direction close to the patient, so that the distance between the coil and the patient is closer, therefore, the accuracy of nuclear magnetic resonance detection is improved, if the position of the moving bed 1 is adjusted to be limited, the position to be diagnosed of a patient still has deviation with the coil position, medical staff can manually push the sliding block 4 to slide in the sliding groove 3 so as to further drive the placing frame 12 to move, the placing frame 12 can drive the coil to move so as to change the diagnosis position, the effect that the coil position can be freely adjusted to adapt to different patients is achieved, the application range is wide, the nuclear magnetic resonance detection effect is improved, it needs to be stated that the pin shaft is arranged outside the sliding block 4, the pin hole corresponding to the pin shaft is formed in the sliding groove 3, and the sliding block 4 is fixed through the pin shaft and the pin hole after the sliding block 4 is adjusted;
after the position of the placing frame 12 is adjusted, the medical staff can further rotate the adjusting rotating rod 13, and the adjusting rotating rod 13 can drive the placing frame 12 to slide after being rotated, so that the position between the pair of placing frames 12 is adjusted, and the adjustability of the nuclear magnetic resonance coil is further expanded; when some body types are fat, big belly exists, or the legs of a patient need to be diagnosed, medical staff can adjust the heights of the lifting screws 6 to enable the placing frame 12 to be inclined, so that the coil is more attached to the body of the patient, in the process, due to different heights among the lifting screws 6, the placing frame 12 can pull the rotating ball 9 to rotate in the limiting shell 8 under the action of gravity, and the placing frame 12 can be inclined through the arrangement of the limiting shell 8 and the rotating ball 9; the arrangement of the support frame 11 can support the placing frame 12, so that the situation that the adjusting rotating rod 13 is greatly abraded in the process of adjusting the placing frame 12 due to the fact that all pressure of the placing frame 12 acts on the adjusting rotating rod 13 is avoided; in the process of movement of the lifting screw 6, the lifting spring 18 is simultaneously stretched to deform the lifting screw 6, and the lifting spring 18 applies a tensile force to the lifting screw 6, so that the gravity of the equipment is prevented from acting on the threads between the lifting screw 6 and the adjusting sleeve 7, the thread pressure between the lifting screw 6 and the adjusting sleeve 7 is reduced, and the service life of the equipment is prolonged;
after the position of the placing frame 12 is adjusted, medical staff can manually rotate the pair of limiting plates 14, so that the pair of limiting plates 14 can limit a patient on the moving bed 1, the patient is prevented from moving in a large range during nuclear magnetic resonance to cause deviation of a detection result, the buffer sponge 15 can effectively protect the inner walls of the limiting plates 14, the limiting plates 14 are prevented from being damaged due to movement of the patient during nuclear magnetic resonance, and the patient is also protected from being injured;
after the patient is detected and leaves, the medical staff can manually rotate the limiting plate 14 to enable the limiting plate to rotate towards the central position of the placing frame 12 until the limiting plate can not rotate, in the process, the limiting plate 14 rotates to drive the extrusion rod 16 to rotate at the same time, the extrusion rod 16 penetrates through the extrusion groove to extrude the liquid storage bag 17 in the rotating process, disinfectant stored in the liquid storage bag 17 can be sprayed out after the liquid storage bag 17 receives extrusion force, the sprayed disinfectant is sprinkled on the surface of the moving bed 1 and the inside of the detection shell 2, and therefore the equipment is disinfected and convenient to use next time, it needs to be noted that the extrusion rod 16 cannot extrude the liquid storage bag 17 in the normal limiting process, and the extrusion rod 16 can extrude the liquid storage bag 17 only after the limiting plate 14 rotates to limit;
some infants often cannot control the infants not to move during the nuclear magnetic resonance period, and through the arrangement of the connecting elastic rope 19 and the counterweight ball 20, the counterweight ball 20 can shake to a certain degree along with the operation of equipment in the detection process, so that the eyes of the infants are attracted, and the external reflective bright sheets can reflect certain light to further attract the eyes of the infants in the shaking process, so that the attention of the infants can be dispersed, the motion amplitude of the infants is reduced, the difficulty of the nuclear magnetic resonance of the infants is reduced to a certain degree, the infants do not need to take medicines such as hypnotics to carry out the nuclear magnetic resonance, the body health of the infants is protected, and the design of the limiting plate 14 can limit the motion of the infants to a certain degree; in the shaking process of the counterweight ball 20, the counterweight ball 20 can drive the impact ball 21 in the counterweight ball 20 to move, and the impact balls 21 can collide with each other in the moving process, so that the noise of sand and sand is generated, and the attraction effect of the counterweight ball 20 on the attention of infants is further improved;
after the position of the limiting shell 8 is adjusted, medical personnel can manually rotate the adjusting rod 22 to push the brake block 23 to slide in the limiting shell 8 until the brake block 23 is contacted with the rotating ball 9, so that the rotating ball 9 is limited, the rotating ball 9 is prevented from shaking in the subsequent nuclear magnetic resonance process, and the friction force between the brake block 23 and the rotating ball 9 can be further increased by the arrangement of rubber particles, so that the braking effect is improved;
it should be noted that all the components described above should be made of materials that are not affected by magnetic force.
The front, the back, the left, the right, the upper and the lower are all based on figure 1 in the attached drawings of the specification, according to the standard of the observation angle of a person, the side of the device facing an observer is defined as the front, the left side of the observer is defined as the left, and the like.
