Limb positioner for nuclear magnetic resonance examination of heart

Abstract

A limb positioner for heart nuclear magnetic resonance examination effectively solves the problems that when a patient is subjected to heart nuclear magnetic resonance examination, the patient can lie on an examination bed and keep flat with the help of a step, so that the patient who is inconvenient to move and just subjected to an operation is inconvenient to transfer, the workload of medical staff is increased, and the workload of the medical staff is reduced. The problems that the head and four limbs of a patient cannot be properly fixed in an auxiliary mode when the patient is examined so as to help the patient complete the examination, and buzzing noise generated during the examination cannot be relieved, so that the irritable emotion of the patient when the patient is located in a long and narrow closed space cannot be relieved, and the examination accuracy cannot be influenced are solved. A first shaft body is rotatably connected to the middle of the rear side of the base, a first bed plate is arranged on the upper portion of the base and can move up and down along with rotation of the first shaft body, a third bed plate is slidably connected to the middle of the first bed plate, and a second bed plate is slidably connected to the front side of the middle of the third bed plate; a second connecting rod is hinged to the front end right side of the third bed board.

Description

technical field [0001] The invention relates to the technical field of medical assistance, in particular to a limb positioner for cardiac nuclear magnetic examination. Background technique [0002] Nuclear magnetic resonance is to use the characteristics of nuclear spin motion to place the human body in a special external magnetic field, and excite the hydrogen nuclei in the human body by radio frequency pulses, causing the hydrogen nuclei to resonate and absorb energy. After the radio frequency pulse is stopped, the hydrogen nuclei press A method of transmitting an electrical signal at a specific frequency and releasing the absorbed energy, which is recorded by a receiver outside the body and processed by an electronic computer to obtain an image. In the field of modern medicine, nuclear magnetic resonance examination has become one of the routine examinations. The existing nuclear magnetic resonance The resonance examination bed has a simple structure and is integrated wit...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a limb positioner for cardiac nuclear magnetic resonance examination. This design effectively solves the problem that patients need to use steps to lie down on the examination bed and keep them flat when performing cardiac nuclear magnetic resonance examination. Lying down, it is very inconvenient for the transfer of patients with limited mobility and who have just undergone surgery, which increases the workload of medical staff. At the same time, it is impossible to properly fix the patient's head and limbs during the patient's examination to help them complete the examination. It also cannot alleviate the buzzing noise generated during the examination, so that it cannot alleviate the patient's irritability when they are in a narrow and long confined space, which affects the accuracy of the examination.
