Description

PET-CT examining table

Technical Field

The invention relates to the field of medical equipment, in particular to a PET-CT examining table.

Background

PET/CT is known as Positron Emission Computed Tomography (PET/CT), and is an integrated perfect fusion of PET and CT. PET/CT provides detailed function and metabolism of focus, CT provides accurate dissection and location of focus, and tomographic image of whole body in different directions can be obtained through once imaging. PET/CT is a new milestone for the development of life science and medical imaging technology at present, and is mainly clinically applied to the early detection and diagnosis of serious diseases in the fields of tumors, brains, hearts and the like.

Before examination, the most common whole body was used¹⁸F-FDG PET/CT as an example, the injection is completed¹⁸And (5) after the F-FDG is carried out for 60-90min, the examinee leaves a waiting room and starts to be checked on the computer. If the examinee can not lie down by himself, the medical staff or family members are often required to assist, and the radioactive developer in the examinee becomes a movable 'radioactive source', which can cause the medical staff or family members to be irradiated. Different examinees's physical condition is different, and current head stock and neck brace are fixed height and size, can't adjust according to examinee's self condition, lead to the comfort among the inspection process not good enough.

In the examination, if the whole body PET/CT imaging is performed, in order to avoid the artifact caused by the imaging of the arms to the trunk, the examinee needs to lift the two arms up to cross the top of the head for about 20 minutes; if it is not¹³N-NH₃PET/CT absolute quantitative myocardial perfusion imaging requires the subject to be lifted both arms over the top of the head for about 15 minutes at rest and 30 minutes later to be lifted again both arms over the top of the head for about 15 minutes under load. In this process, the examinee often feels tired due to the suspension of the arm for a long time, and even can not insist on doing the examination. In addition, in the process of examination, due to the necessity of radiation protection, medical technicians mostly communicate with the examinees through voice broadcast at present to remind the examinees of the cautions, but a part of the examinees still have poor communication effect, so that the working efficiency and the imaging quality are greatly influenced. In addition, some patients with severe illness are unconscious and risk falling from the examination table during the examination.

After the examination is finished, for some weak patients, family members or medical workers are also required to assist the patients to get up, so that the possibility of radiation injury of the family members or the medical workers is increased invisibly.

Therefore, it is necessary to solve the above-mentioned technical problems.

The invention relates to the following principle:

after the patient enters the examination room, the patient sits on the bed board II, the waist leans against the bed board I, the bed board I is provided with the telescopic fixing belt, and the examinee can fix the waist on the bed board I by himself. A head support and a neck support are arranged above the bed plate I and can be adjusted up and down, and a doctor can control the positions and the heights of the head support and the neck support through a controller, so that the examined person is in a comfortable state. In the process, a doctor and a detected person can communicate through a voice system of a tablet computer, and the tablet computer can also perform corresponding animation demonstration, so that the patient is helped to adjust the position better. After the head and neck position is adjusted, the guardrail is lifted and locked through the locking piece, and the bed plate 1 is gradually leveled under the action of the pushing device. In the process of gradually laying the bed board I, the examinee can adapt to the process of lying flat by grasping the guardrail. After the patient lies flat, upper arm strutting arrangement can remove to both sides under the effect of controller to lift on making two upper arms and cross the overhead occasionally and support, avoid unsettledly, not only avoid causing the ghost because of the arm to the trunk video picture, also can alleviate the patient because of the arm lifts the sour poverty that causes for a long time, simultaneously, can alleviate the unable complex problem of neck shoulder problematic patient because of painful in the testing process to a certain extent. For the examination items requiring the injection of the developer in the process, the double-arm fixing device can be correspondingly adjusted according to the injection requirement, so that the injection part (for example, the back of the hand) is effectively exposed, and the posture of the injection arm is adjusted, so that the developer can enter the body to complete the development. To some patients who have the danger of falling down from the bed, the guardrail and the fixed band can effectively avoid falling down from the bed, and the safety is improved. In the examination process, because the operation room computer and the flat plate of the examination room are provided with the NFC chips, the system can remind the attention items in each examination step in real time, such as lifting of the two arms, placing of the two arms on two sides of the body, air suction, breath holding and the like. After the examination is finished, some patients need to carry out delayed imaging, and the tablet personal computer can inform the patients to enter the waiting area again for waiting through pictures and voices. After the examinee finishes the examination, the bed plate I is gradually erected, the examinee sits up, the guardrail is put down, the patient can unfold the fixing belt of the bed plate I and leaves the examination room, and at the moment, the head support, the neck support and the double-arm supporting device also return to the standard state before the examination.
