The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0027] A nuclear magnetic resonance apparatus, such as Figure 1-Figure 5As shown, it comprises a magnetic resonance body 1 and a support frame 2 arranged at the front side of the magnetic resonance body 1, a movable plate 3 is movably arranged on the support frame 2, a patient can lie on the movable plate 3, and the movable plate 3 drives the patient to be pushed into the magnetic resonance body 1 for examination, and two groups of guardrail mechanisms 4 and an adjustment mechanism 5 for driving the two groups of guardrail mechanisms 4 to move toward each other are arranged on the movable plate 3;
[0028] The guardrail mechanism 4 includes a first slide groove 44 provided on the movable plate 3 and a first slider 41 slidably connected in the first slide groove 44, a guardrail 42 is rotatably connected to the first slider 41, a torsion spring 43 is provided between the guardrail 42 and the first slider 41, and the guardrail mechanism 4 also includes a driving assembly 45 for driving the guardrail 42 to rotate, the driving assembly 45 includes a rack 451 fixedly connected or plugged into the movable plate 3 and a gear 452 integrally formed with the rotating shaft of the guardrail 42, the rack 451 meshes with the gear 452;
[0029] The adjusting mechanism 5 includes a rotating shaft 51 rotatably connected to the movable plate 3 and an external thread 52 arranged on the outer wall of the rotating shaft 51, the external thread 52 is integrally formed with the rotating shaft 51, the inner side of the first slider 41 is tapped with an internal thread, the rotating shaft 51 is threadedly connected to the first slider 41, one end of the rotating shaft 51 passes through any side of the movable plate 3 to be exposed, or the rotating shaft 51 directly passes through both ends of the movable plate 3 to be exposed.
[0030] Among them, in specific use: first, the medical staff can help the patient to lie on the movable plate 3. Due to the initial state (such as Figure 1 As shown in the figure, the guardrail 42 and the movable plate 3 are in a mutually horizontal state, and the torsion spring 43 is in a deformed state, so the guardrail 42 will not hinder the patient from getting on the bed. When the patient lies on the movable plate 3 and adjusts the lying position, the medical staff can rotate the rotating shaft 51. The rotation of the rotating shaft 51 will drive the two first sliders 41 to move toward each other. The movement of the first slider 41 will drive the guardrail 42 to move closer to the patient. When the guardrail 42 moves, it drives the gear 452 to move. Since the gear 452 is meshed with the rack 451, the gear 452 will drive the guardrail 42 to rotate when it moves. When the gear 452 is completely disengaged from the rack 451 (as shown in the figure, the guardrail 42 is in a horizontal state with the movable plate 3, and the torsion spring 43 is in a deformed state, ... and the guardrail 42 will not hinder the patient from getting on the bed. Figure 2As shown in the figure, the guardrail 42 will be in a state perpendicular to the movable plate 3, and the torsion spring 43 will be reset from the deformed state. Due to the setting of the torsion spring 43, the guardrail 42 will not be easily pushed by people to cause rotation. When the guardrail 42 moves in the direction close to the patient, it will eventually contact the patient's arm. Thus, the two guardrails 42 will contact the patient's arm, thereby clamping and limiting the patient's arm to prevent the patient's arm from moving unconsciously and affecting the imaging effect. After the patient is examined by the nuclear magnetic resonance apparatus, the operator can rotate the rotating shaft 51 to make the first slider 41 move away from the patient to a certain extent. The movement of the first slider 41 drives the guardrail 42 to move. When the gear 452 on the rotating shaft of the guardrail 42 moves to contact with the rack 451, the rack 451 will drive the gear 452 to rotate, and the rotation of the gear 452 will drive the guardrail 42 to rotate, so that the guardrail 42 is in a state of being horizontal with the movable plate 3, and the torsion spring 43 is deformed, so that the guardrail 42 is in a horizontal state, which is convenient for the patient to get off the movable plate 3.
[0031] To summarize, the operator only needs to rotate the rotating shaft 51 to change the guardrail 42 from a horizontal state to a vertical state. At the same time, the guardrail 42 can also move toward the patient to clamp and limit the patient's arm to prevent the patient's arm from moving unconsciously and affecting the imaging effect. The operator also only needs to rotate the rotating shaft 51 to move the guardrail 42 away from the patient. At the same time, the guardrail 42 changes from a vertical state to a horizontal state, which is convenient for the patient to get off the movable plate 3. Therefore, when the patient moves the plate 3 up and down, there is no guardrail 42 to block it, which is convenient for the patient to move the plate 3 up and down. The guardrail 42 can clamp and limit the arm to ensure the imaging effect. These functions can be achieved by rotating the rotating shaft 51, so that convenient operation is achieved.
[0032] like Figure 6 As shown, the nuclear magnetic resonance apparatus also includes a blocking mechanism 6 for blocking the arm from moving upward, the blocking mechanism 6 includes a second slide groove 61 opened on the guardrail 42 and a second slider 62 slidably connected in the second slide groove 61, a baffle 63 is rotatably connected to the second slider 62, and the baffle 63 is rotated to above the arm, and the baffle 63 blocks the arm from lifting upward, the baffle 63 is in a convex shape, and the size of the baffle 63 at one end away from the second slider 62 is larger than the other end.
[0033] When the guardrail 42 and the movable plate 3 are in a vertical state, the operator can slide the second slider 62 according to the position of the patient's hand, and the second slider 62 drives the baffle 63 to move. When it is adjusted to the corresponding position, the operator can rotate the baffle 63 so that one end of the baffle 63 is located directly above the hand. When the patient unconsciously lifts his arm up, the baffle 63 will prevent the patient's hand from lifting up, thereby further preventing the patient's arm from unconsciously moving around and affecting the imaging effect. When there is no need to block the patient's hand, it is only necessary to rotate the baffle 63 to a horizontal state with the guardrail 42.
[0034] A knob 53 is disposed on one end of the rotating shaft 51 that is exposed to the outside. The knob 53 is in a cross shape.
[0035] The knob 53 is provided to facilitate an operator to rotate the shaft 51 through the knob 53 .
[0036] The guardrail 42 is provided with a plurality of through holes 422 evenly spaced apart from each other.
[0037] When the guardrail 42 clamps the patient's arm to a limited position, the through hole 422 is provided to facilitate air circulation, thereby improving the comfort of the patient's hand.
[0038] A protective member 7 is provided on the side of the guardrail 42 corresponding to the patient's arm. The protective member 7 is an integrally formed sponge pad, or is composed of a plurality of evenly spaced sponge pads.
[0039] Among them, when the protective member 7 is provided on the guardrail 42, when the patient's arm is clamped and limited, the protective member 7 will contact the patient's arm. Since the protective member 7 has a cushioning property, the comfort of the patient's hand can be improved.
