The invention relates to a magnetic resonance fixing device. The magnetic resonance fixing device effectively solves the problem that when a child patient is subjected to magnetic resonance, the bodyposition cannot be kept unchanged for a long time. The device comprises a box body, wherein a plurality of clamping devices are arranged on the left side and the right side in the box body respectively, the clamping devices on the left side and the clamping devices on the right side are symmetrical in structure, each clamping device on the right side comprises a transmission plate, a rotating shaft and a ratchet bar, a pawl is hinged to the right end of each transmission plate, a gear bar is arranged at the lower end of each transmission plate, and a clamping plate is connected to the left endof each transmission plate through a corresponding pressure spring; a driven plate is arranged at the lower end of each clamping plate, inserting grooves are formed in each gear bar and each driven plate respectively, a crown gear is coaxially arranged on each rotating shaft, a crown-shaped gear is coaxially arranged on each rotating shaft in a sleeving manner, a main gear is coaxially arranged at the rear end of each crown-shaped gear through a corresponding connecting ring, a connecting rod is rotationally connected to each connecting ring, a square frame is arranged at the rear end of eachconnecting rod, an inserting block is in sliding connection to each square frame, and the left end surface of each inserting block is a front-right-back-left inclined surface; The device is novel inconcept, ingenious in structure, convenient to operate and high in practicability.
Description
technical field [0001] The invention relates to the technical field of magnetic resonance auxiliary equipment, in particular to a magnetic resonance fixation device. Background technique [0002] Magnetic resonance examination is a widely used examination method at present, and the magnetic resonance signal is generated by applying the phenomenon of magnetic resonance to form an image. The MRI examination takes a long time, and when MRI is performed, the patient usually needs to keep a fixed posture for a long time, and for a child patient, it is impossible to keep a fixed posture for a long time. In order to check the children smoothly, the commonly used methods to prevent the children from moving around are injecting tranquilizers into the children's body or making the children take sleeping and tranquilizing drugs, but taking the drugs will cause adverse psychological effects on the children. reaction, and the drug will cause certain damage to the child's body.
