Description

Special cardiac machine seat position fixing device

Technical Field

The utility model belongs to the field of medical equipment, particularly, relate to a special frame chair body position fixing device of heart.

Background

Nuclear medicine originated at the end of the nineteenth century, and has formally entered the clinic in 1951 through long-term research development. In 1962, david Kuhl invented emission reconstruction tomography, namely SPECT and PET. The basic principle of SPECT (Single-Photon Emission Computed Tomography) is that a Single-Photon/positron radioisotope drug with a proper half-life is taken in a detection object (patient), the drug is combined with an observation part of the patient, gamma rays are emitted from a fault due to radioactive decay, an external detector records the position of the rays, imaging data of the distribution condition of the radionuclide is obtained through rotation, and a series of fault plane images are established, so that the function or the metabolic condition of each organ is analyzed to diagnose the disease. Obviously improves the sensitivity of nuclear medicine diagnosis and can find small differential radioactive foci of adjacent tissues.

Cadmium Zinc Telluride (CZT) semiconductor detector is applied to the Medical field for the first time by Spectrum Dynamics Medical of Israel in 2005, and a special SPECT system D-SPECT for the first digital heart in the world is promoted. The D-SPECT heart special machine (referred to as the heart special machine for short in the text) is specially designed for heart examination, has qualitative difference compared with the prior ordinary SPECT, has better definition and can clearly display ischemic and infarcted myocardium, and has high sensitivity characteristic which can allow lower dose of radionuclide to complete examination and reduce radiation dose.

Fig. 7 provides an outline schematic diagram of the prior D-SPECT heart special machine, and when the machine is used, a detection object sits on a detection seat for examination. The detection object needs to be collected in a stable state, the detection seat in the folding mode adopted by the examination bed can not adapt to patients with different body types well, particularly when the body state of the patient is not good, the head, the neck and the waist of the patient feel uncomfortable, the compliance of the patient is reduced, and therefore body position displacement is generated, movement artifacts appear in the collected image, and the image quality and the evaluation precision are affected.

The existing solution is that the doctor's advice detection object (patient) tries to cooperate, concentrates on consciously, keeps the body position stationary, places a common bolster at most in the neck, lets the patient both hands rely on the acquisition probe of equipment to try to keep stable, but a lot of patients still can feel uncomfortable, and the bolster of neck often can slide, and the body displacement also can not be solved well. Similar situations where patients have difficulty adequately fitting the examination are common in hospitals, for example, the utility model CN217138088U discloses a head fixing device for nuclear medicine examination, and the description describes: at present nuclear medicine equipment generally does not equip fixing device, and the examining table comfort level is relatively poor, and the person being examined is difficult to remain motionless for a long time, and head range of motion is great moreover, and it is more difficult to remain fixed than other body parts in the inspection process, especially to the person being examined condition of old and weak.
