[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] see Figure 1 to Figure 5 , The present invention provides a PET-CT examination bed, including a bed frame 1, a bed board I2, a bed board II3, a neck support 4, a head support 5 and an upper arm support seat 6, and the bed board I2 and the bed board II3 are installed on the bed frame 1. , the bed board I2 is hinged with the bed board Ⅱ3, the bed board is provided with pads, which can improve the comfort, the bed board I2 and the bed frame 1 are connected and installed with a push device, which can push the bed board I2 up or flatten to assist the patient to get up. and lying down, a telescopic device is also installed on the bed board I2, the neck support 4, the head support 5 and the upper arm support base 6 are all installed on the telescopic device, and the respective positions are adjusted through the telescopic device, so that the patient is in a comfortable position , There are two upper arm support bases 6, which are distributed on the left and right sides of the head support 5, and are respectively used to place the arms of the patient on both sides, so as to avoid the soreness caused by long-term detection.

[0030] As a preferred embodiment, this embodiment also includes a controller 7 , a folding frame 8 and a slider 9 , the controller 7 is connected and installed with the slider 9 through the folding frame 8 , and the bed frame 1 is provided with a chute , a drive motor is installed inside the slider 9, which can drive the slider 9 to move in the chute, and the controller 7 is provided with a voice call function, which is convenient for the patient to communicate with the doctor in real time, and to determine the inspection steps and subsequent inspection points. The setting ensures that when the patient enters the CT machine for examination, the controller 7 can be slid to the patient's footsteps to avoid affecting the examination process.

[0031] As a preferred embodiment, the push device described in this embodiment includes a push motor 10 and a push rod 11 , the push rod 11 is controlled to be pushed out by the push motor 10 , and can push up the bed board I2 .

[0032] As a preferred embodiment, the telescopic device described in this embodiment includes a first telescopic motor 12 , a second telescopic motor 13 and a connecting bracket. There are multiple connecting brackets. The first telescopic motor 12 is fixed on the bed frame 1 . The neck support 4 and the head support 5 are respectively fitted and installed with the first telescopic motor 11 through the connecting bracket, the second telescopic motor 13 is fixed under the head support 5, and the two upper arm support bases 6 are respectively connected with the second telescopic motor 11 through the connecting bracket. The motor 13 is adapted to be installed. A lift motor 14 is further disposed between each upper arm support base 6 and the second telescopic motor 13 , and the position of the upper arm support base 6 can be adjusted in the vertical direction.

[0033] As a preferred embodiment, guardrails 15 are respectively installed on both sides of the bed frame 1 described in this embodiment to prevent the patient from falling off the examination bed during the examination. Further, the guardrail 15 is hinged with the bed frame 1 , and locking members 16 are installed on the bed frame 1 , and the position of the guardrail 15 is fixed by the locking members 16 . Further, a fixing belt 17 is also installed on the bed frame 1 to better protect the patient.

[0034] As a preferred embodiment, the controller 7 described in this embodiment is a smart tablet, and the smart tablet is connected to the drive motor, the push motor 10, the first retractable motor 12, the second retractable motor 13, and the lift motor 14 through circuits, respectively. A touch switch for controlling the push device and the telescopic device is arranged on the smart tablet.

[0035] The principle involved in the present invention is:

[0036]After the patient enters the examination room, he first sits on the bed board II, and his waist rests on the bed board I. There is a retractable fixing belt on the bed board I, and the examinee can fix the waist on the bed board I by himself. There are a head support and a neck support above the bed board I, both of which can be adjusted up and down. The doctor can control the position and height of the head support and the neck support through the controller, so that the subject is in a comfortable state. During this process, the physician and the examinee can communicate through the tablet's voice system, and the tablet computer will also perform corresponding animation demonstrations to help the patient better adjust the position. After the position of the head and neck is adjusted, the guardrail is raised and locked by the locking piece, and the bed board 1 is gradually laid flat under the action of the pushing device. During the gradual laying of the bed board I, the subject can adapt to the laying-flat process by grasping the guardrail. After the patient lies flat, the upper arm support device can be moved to both sides under the action of the controller, so that the upper arms can be supported when they are raised over the top of the head to avoid hanging, which not only avoids artifacts caused by the arms to the trunk imaging, but also It relieves the patient's soreness and sleepiness caused by lifting the arm for a long time. At the same time, it can relieve the problem that patients with neck and shoulder problems cannot cooperate due to pain during the examination process to a certain extent. For inspection items that require imaging agent injection during the process, the dual-arm fixing device can be adjusted according to the injection requirements, so as to effectively expose the injection site (such as the back of the hand) and adjust the injection arm posture, which is conducive to the entry of imaging agent. In vivo, imaging is done. For some patients who are at risk of falling from bed, guardrails and fixed belts can effectively avoid falling from bed and improve safety. During the inspection, because the computer in the operating room and the tablet in the inspection room have NFC chips, it can remind you of the precautions in each step of the inspection in real time, such as raising your arms, placing your arms on your sides, inhaling, holding your breath, etc. After the examination, some patients need delayed imaging, and the tablet computer can inform the patient to enter the waiting area again through pictures and voice. After the subject completes the examination, the bed board I gradually stands upright, the subject sits up, and the guardrail is lowered. The patient can unfasten the fixing belt of the bed board I and leave the examination room. At this time, the head support, neck support and arm support devices also return. to the standard state before the inspection.

[0037] Only the preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above-mentioned embodiments, and within the scope of knowledge possessed by those of ordinary skill in the art, various aspects can also be made without departing from the purpose of the present invention. Various changes should be included within the protection scope of the present invention.
