Nuclear magnetic resonance medical diagnosis movable bed

Abstract

The invention provides a nuclear magnetic resonance medical diagnosis movable bed, and belongs to the technical field of nuclear magnetic resonance medical examination equipment. The nuclear magnetic resonance medical diagnosis movable bed has the advantages that when a driving screw and a main conical friction roller rotate, a driving lifting structure moves upwards or downwards along the driving screw under the rotation of the driving screw, a driving annular lifting sleeve is connected with the outer side face of the main conical friction roller and the outer side face of a subsidiary conical friction roller in an abutted mode, and when the driving lifting structure moves upwards or downwards, the driving annular lifting sleeve stably moves upwards or downwards along the driving screw together with a driving guide plate of the driving lifting structure; the height of a whole bed board is stably and smoothly adjusted, only one person is needed to achieve the adjustment of the height of the bed board, the height of the bed board is adjusted moderately according to the needs of each patient, the height which a patient requires during the examination is reached, the bed is convenient to adjust, and when nuclear magnetic resonance medical diagnosis is conducted on the patient, the operation is flexible, and the workload of medical staff is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance medical detection equipment, in particular to a moving bed for nuclear magnetic resonance medical diagnosis. Background technique [0002] MRI medical diagnostic equipment usually includes a magnet with a circular cavity and a moving bed. The mobile bed is to send the patient to the position designated by the system for scanning. Usually, the mobile bed needs to have two directions of movement, that is, vertical movement and horizontal movement, so as to send the patient on the mobile bed to the circular cavity magnet specified location. In the vertical motion mechanism that realizes vertical motion, the height can be raised and lowered by using the traditional scissor beam structure through angle changes. [0003] In the scissor beam structure used in the traditional lifting scheme, the push rod device is arranged vertically upwards. In this way, since the push rod device i...

Problems solved by technology

[0003] In the scissor beam structure used in the traditional lifting scheme, the push rod device is arranged vertically upwards. In this way, since the push rod device is usually a two-stage hydraulic push rod, the lowering height of the hospital bed is very limited in this case, so that the hospital bed cannot be lowered to Lower position, thus causing great inconvenience to some patients with limited mobility
