[0035] Embodiment 2

[0036] PPT Guiding the Patient's CT Examination Process:

[0037] I. Anti-virus Operations in Compartments for Suspected Patients and Confirmed Patients Who Can Take Care of Themselves:

[0038] 1. The scanning technician performs anti-virus operations in the operation control room in a compartment:

[0039] 1.1. Call the patient to get ready through the existing video queuing system;

[0040] 1.2. Open the electric lead door through the electric lead door remote control system;

[0041] 1.3. Play a self-made computer PPT on the TV display device 13 and the technician guides the patient's operation in a compartment;

[0042] 2. Guide the patient's anti-virus operation through the PPT on the computer or controller in the scanning operation control room by the scanning technician:

[0043] 2.1. The patient is led to the CT room by the fever clinic guide. The scanning technician guides the patient and the accompanying personnel to perform hand hygiene with the hand sanitizer at the machine room door or wear disposable gloves;

[0044] 2.2. After the patient enters Machine Room B, guide the patient to first wear a disposable hat, then a lead hat, put on disposable shoe covers, and lay a disposable sheet (select a middle sheet). The sheet should cover the headrest above and completely cover the lead apron 8 laid on the main examination bed 9 below;

[0045] 2.3. Guide the patient to take off the coat and remove metal items within the scanning range, such as necklaces, underwear, etc.;

[0046] 2.4. Guide the patient to lie on the scanning bed, with the head on the headrest and the forearms crossed and raised above the head

[0047] 2.5. Tell the patient to eliminate nervousness, such as saying "This is just a check-up, it's safe, don't worry, we will always pay attention to you", and make sure to cooperate with the breathing and holding exercises guided by the machine;

[0048] 2.6. The scanning technician adjusts the patient to the scanning position through the machine's built-in examination bed lifting and exiting system, and asks the accompanying personnel to leave the machine room B and close the electric lead door;

[0049] 2.7. After the scan is completed, the image is uploaded to PACS. The scanning technician adjusts the examination bed to the position of the patient, guides the patient to get off the examination bed, puts the lead cap back in place, and throws the disposable bed sheet 7 into the medical waste bin in the machine room;

[0050] 2.8. Instruct the patient to put on his coat, take his belongings with him, take off his disposable shoe covers and hat after leaving the room, throw them into the medical waste bin at the door of the room, and disinfect his hands again;

[0051] 2.9. While waiting for the patient to get dressed, the scanning technician will browse the images. If lung inflammation is found, he / she will immediately contact the emergency department for diagnosis, report the critical value, and alert the accompanying personnel of the fever clinic;

[0052] 2.10. If the patient is a suspected patient with no lung inflammation, the scanning technician opens the electric lead door, and the patient leaves the room to handle the disposable shoe covers, gloves, and hats, and performs hand hygiene again. After the accompanying personnel take him out of the Beidou CT, the next patient's lung CT examination can be performed immediately; if the patient is a confirmed case who can take care of himself, the scanning room needs to be disinfected for 60 to 80 minutes after the patient leaves before the next patient's lung CT examination can be performed;

[0053] 2. Radiation protection in the compartments of suspected patients and confirmed patients who can take care of themselves:

[0054] 1. Instruct patients to wear disposable caps first and then lead caps. To avoid contact infection, additional steps and caps that did not require disposable caps were added;

[0055] 2. Place a lead apron on the examination bed first and then instruct the patient to place a disposable sheet. The lead apron is placed 450mm away from the headrest. It was originally covered on the patient, but now it is placed under the patient. A disposable sheet is added between the lead apron and the patient's body to avoid damage to the lead apron caused by repeated disinfection due to contact. In addition, the disposable sheet can also be used for isolation;

[0056] 3. The scanning angle of the positioning image is 180°. The original lead apron was placed above the patient and used 0°. Now the lead apron is placed below the patient and uses 180°, which can also reduce the radiation damage to the patient.

[0057] Critical confirmed cases and suspected patients who are unable to take care of themselves are not suitable for using PPT to guide the operation of preventing virus and radiation in separate compartments: The scanning technician needs to be equipped with level-three protection to enter the computer room to assist the patient in preventing virus and radiation; The inspection method of this system and the laying method of the lead apron remain unchanged, and the multimedia system is used as an auxiliary or not used.

[0058] The present utility model proposes to enable patients who can take care of themselves to watch the inspection preparation video and the close-range non-contact observation guidance of the inspection scanning technician, and finally realize the non-contact inspection of the patient and confirm whether the patient is a virus infected person, upload and report the inspection result information in the first time, and minimize the probability of infection of the CT inspection scanning technician through contact. It realizes the maximum protection for medical technicians without affecting the progress of the inspection work, and also provides guarantee for medical technicians to provide more and longer social services.
