Magnetic resonance imaging medical-treatment detection bed

Abstract

The invention provides a magnetic resonance imaging medical-treatment detection bed, belonging to the technical field of magnetic resonance imaging medical-treatment apparatus and instruments. According to the technical scheme, the magnetic resonance imaging medical-treatment detection bed comprises a base plate, support legs, guiding screw rods and a base plate, wherein the support legs are arranged on the bottom surface of the base plate, the guiding screw rods are respectively arranged on each corner of the top surface of the base plate, and the bed plate is in threaded connection to the guiding screw rods; and a power transmission mechanism and an adjustment structure are arranged between the bed plate and the base plate. The magnetic resonance imaging medical-treatment detection bed has the beneficial effects that the height adjustment process of the bed plate is relatively smooth, the operation is flexible during the magnetic resonance imaging medical-treatment detection of a patient, and the workload of a medical worker is greatly relieved.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance medical equipment, in particular to a medical detection bed for nuclear magnetic resonance. Background technique [0002] In MRI medical diagnostic equipment, it usually includes a magnet with a circular cavity and an examination table. The examination bed is responsible for sending the patient to the position designated by the system for scanning. Usually, the examination bed needs to have two directions of movement, that is, vertical movement and horizontal movement, in order to send the patient on the examination 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] The scissor beam structure used in the traditional lifting scheme includes the following structural forms: In the first structural f...

Problems solved by technology

[0003] The scissor beam structure used in the traditional lifting scheme includes the following structural forms: In the first structural form of the scissor beam structure, the push rod device is arranged vertically upwards, so that since the push rod device is usually a two-stage hydraulic push rod , in this case, the falling height of the hospital bed is very limited, so that the hospital bed cannot be lowered to a lower position, which brings great inconvenience to some patients with limited mobility; in the scissor beam structure of the second structural form, the The apex of the push rod device is placed at the center of the scissor beam, and the other end is fixed on the bottom plate, so that the minimum height of the hospital bed can be reduced, but when the examination bed is lowered to a certain height, the thrust of the push rod device motor will increase sharply. This requires an increase in the power of the motor, which will undoubtedly increase the cost
