Description

Closed audio-visual device used before PET-CT examination

Technical Field

The utility model relates to a medical examination auxiliary device, in particular to a closed audio-visual device used before PET-CT examination.

Background

PET-CT can accurately locate epileptic foci, and is also a unique examination method for diagnosing Parkinson's disease, senile dementia and other diseases. The treatment of epilepsy is one of ten major medical problems in the world, and accurate positioning of an epilepsy focus is difficult to achieve. Because the sugar metabolism of the cerebral cortex and the cerebral nerve nuclei is changed by stress, excitement, uneasiness, etc., it is necessary to keep the patient quiet and to normally distribute the radiopharmaceutical in a dim or low light state.

Before a PET-CT is used for scanning a patient, the patient needs to rest in a quiet environment to avoid the increase of metabolism of brain parenchyma and even muscle and soft tissue of the whole body caused by tension, excitation, uneasiness and other emotions, so that the metabolism of the body, namely normal tissue metabolism, is increased, and the signal-to-noise ratio is reduced. To obtain an ideal whole-body scan image, especially for epileptic patients to obtain an accurate localized diagnosis, the patient needs to be visually and aurally occluded prior to performing the scan.

The existing auxiliary equipment only seals the hearing of a patient through a common headset, but external light still causes stimulation to the patient, so that the scanning effect is influenced. If additional visual closure devices are added, the workload of routine maintenance of the equipment by medical personnel is increased, and the complexity of the patient's use is also increased.
