All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please refer to Figure 1-Figure 5 The present invention provides a CT scanning radiation protection bed, and the specific implementation scheme is as follows:

[0026] A CT scanning radiation protection bed comprises a bed body 1, first slide rails 11 are respectively arranged on both sides of the bed body 1, two second slide rails 12 are respectively arranged on the top surface of the bed body 1, the second slide rails 12 are arranged parallel to the first slide rails 11, a head protection device 2 and a neck protection device 3 are slidably connected to the first slide rails 11, and a plurality of body protection devices 4 are slidably connected to the second slide rails 12;

[0027] The head protection device 2 includes a head support tray 21 and a head protection sheet 22. A third slide rail 211 is provided on the top surface of the head support tray 21. The third slide rail 211 is arranged parallel to the second slide rail 12. One end of the head protection sheet 22 is slidably connected to the third slide rail 211. The other end of the head protection sheet 22 contacts the neck protection sheet 32 ​​by bending. The end of the head protection sheet 22 not connected to the third slide rail 211 is arc-shaped. The specification of one end of the arc-shaped head protection sheet 22 is larger than the other end. A triangular mouth and nose notch 221 is provided at one end of the arc-shaped head protection sheet 22. The head protection device 2 is provided with fourth slide rails 212 on both sides respectively. The two fourth slide rails 212 are slidably connected to the neck protection device 3 together. The contact and separation of the head protection sheet 22 and the patient's head are controlled by controlling the sliding of the head protection sheet 22 at the third slide rail 211.

[0028] The sizes of the two ends of the head protection sheet 22 are different. The size of one end of the head protection sheet 22 connected to the third slide rail 211 is roughly consistent with the size of the top surface of the bed body 1, and the size of the other end of the head protection sheet 22 is larger, and the overall shape is an arc;

[0029] The patient's head is placed completely above the head support tray 21, and the head protection sheet 22 between the patient's head and the head support tray 21 can protect the back of the patient's head. At this time, the larger end of the head protection sheet 22 is controlled by the medical staff and flipped to the patient's face. At this time, the larger end of the head protection sheet 22 is located on the patient's face. On the premise that the larger end of the head protection sheet 22 covers the patient's face, its excess part can be controlled by the medical staff to bend until it passes through the binaural area on both sides of the patient's head and contacts the part of the head protection sheet 22 connected to the third slide rail 211. At the same time, a triangular mouth and nose notch 221 is provided at one arc-shaped end of the head protection sheet 22. The setting of the mouth and nose notch 221 can achieve the avoidance of the head protection sheet 22 to the patient's mouth and nose for breathing, thereby avoiding affecting the patient's breathing.

[0030] The neck protection device 3 includes a neck support tray 31, a neck protection sheet 32 ​​and an adjusting button 33. A plurality of fifth slide rails 311 are arranged on the surface of the neck support tray 31. The fifth slide rail 311 is arranged perpendicular to the third slide rail 211. Each of the fifth slide rails 311 is slidably connected to the neck protection sheet 32. A plurality of adjusting buttons 33 are movably connected in each of the fifth slide rails 311.

One end of the adjusting button 33 is movably connected to the fifth slide rail 311. The other end of the adjusting button 33 passes through the neck protection sheet 32 ​​to limit the neck protection sheet 32. One end of the adjusting button 33 extending into the fifth slide rail 311 is limited by the fifth slide rail 311. The adjusting button 33 switches between being limited by the fifth slide rail 311 and canceling being limited by the fifth slide rail 311 by rotating the adjusting button 33.

[0031] The top surface of the neck support tray 31 is made of lead glue, and the adjusting button 33 passes through the neck protection sheet 32 ​​and is slidably connected to the fifth slide rail 311. By controlling the adjusting button 33 to slide on the fifth slide rail 311, the neck protection sheet 32 ​​is driven to slide along the fifth slide rail 311. The end of the adjusting button 33 extending into the fifth slide rail 311 is an arc-shaped strip. When the strip and the fifth slide rail 311 are arranged vertically as a whole, the fifth slide rail 311 will limit the adjusting button 33. At this time, the adjusting button 33 cannot be separated from the fifth slide rail 311, and the adjusting button 33 can only slide along the fifth slide rail 311. The adjusting button 33 is controlled to rotate around its own axis until the long strip connected to the adjusting button 33 is parallel to the fifth slide rail 311. At this time, the fifth slide rail 311 stops limiting the adjusting button 33, and then the adjusting button 33 can be separated from the fifth slide rail 311 at this time, so that the patient's chin and neck can be wrapped. Both ends of the neck protection plate 32 are provided with a plurality of adjusting buttons 33. The adjusting button 33 at one end of the neck protection plate 32 is controlled to separate from the fifth slide rail 311. When the patient's neck contacts the top surface of the neck support tray 31, the separated adjusting button 33 is controlled to be limited by the fifth slide rail 311 again.

[0032] When the patient's head and neck are protected by the head protection plate 22 and the neck protection plate 32 respectively, the head protection plate 22 extends from the back of the patient's head through the top of the patient's head to the patient's face, and uses the excess part to protect the patient's ears and other sides, and uses the mouth and nose notch 221 to reserve an area for breathing. After the mouth and nose notch 221 of the head protection plate 22 is aligned with the patient's mouth and nose, the excess part of the head protection plate 22 at one end where the mouth and nose notch 221 is set can be introduced between the neck protection plate 32 and the patient's neck, thereby further protecting the patient's head and neck.

[0033] The body protection device 4 includes an upper protection sheet 41, a lower protection sheet 42, an upper sliding block 43 and a lower sliding block 44. The two second slide rails 12 are respectively connected with the upper protection sheet 41 and the lower protection sheet 42. One end of the upper protection sheet 41 is slidably connected to one second slide rail 12 through the upper sliding block 43, and one end of the lower protection sheet 42 is slidably connected to the other second slide rail 12 through the lower sliding block 44. The upper protection sheet 41 is composed of an upper lead glue layer 411 and a plurality of upper connecting sheets 412. The lower protection sheet 42 is composed of a lower lead glue layer 421 and a lower connecting sheet 422. The other end of the upper protective sheet 41 is movably connected to the lower lead glue layer 421, and the other end of the lower protective sheet 42 is movably connected to the upper protective sheet 41. A plurality of upper connecting sheets 412 are hinged, and each upper connecting sheet 412 is commonly connected to the upper lead glue layer 411 on a side close to the bed body 1. A plurality of lower connecting sheets 422 are hinged, and each lower connecting sheet 422 is commonly connected to the lower lead glue layer 421 on a side away from the bed body 1. The upper sliding block 43 and the lower sliding block 44 are respectively arranged obliquely on one side connected to the upper connecting sheet 412 and the lower connecting sheet 422.

[0034] By controlling the bending angles between the upper connecting pieces 412, the upper lead glue layer 411 is driven to bend at a certain angle until the upper lead glue layer 411 can cover the top surface of the patient's body, and controlling the bending angles between the lower connecting pieces 422, the lower connecting pieces 422 and the lower lead glue layer 421 are made to fit with the top surface of the bed body 1. At the same time, a Velcro 45 is provided between a lower connecting piece 422 away from the lower sliding block 44 and the upper lead glue layer 411, and a Velcro 45 is provided between an upper connecting piece 412 away from the upper sliding block 43 and the upper lead glue layer 411. Velcro 45 is also provided between the lower lead glue layer 421. By utilizing the two Velcro 45, the connection between the multiple body protection devices 4 and the bed body 1 can realize the protection of the patient's torso and limbs. When the body protection device 4 is slidably connected to the second slide rail 12, the multiple body protection devices 4 can be used to protect the parts of the patient that do not need to be inspected according to the needs of the inspection. At the same time, it covers the limbs of the patient that are rarely covered by the previous lead clothing, which can further reduce the radiation exposure received by the patient.

[0035] The working process of the present invention is as follows: when it is necessary to detect the head and neck of the patient, the multiple body protection devices 4 are controlled to be slidably connected with the second slide rail 12, and then the multiple body protection devices 4 are controlled to cover all parts of the patient's head and neck;

[0036] When it is necessary to examine the patient's head and the area below the neck, the neck protection device 3 is controlled to be slidably connected to the fourth slide rail 212, and then the head protection device 2 is controlled to be slidably connected to the first slide rail 11, and all the adjustment buttons 33 at one end of the neck protection plate 32 are controlled to separate from the fifth slide rail 311, driving the neck protection plate 32 to move accordingly. When the patient's neck is set on the top surface of the neck support tray 31, the neck protection plate 32 is controlled to cover the patient's neck and thyroid area, and at the same time, the adjustment button 33 originally separated from the fifth slide rail 311 is controlled to be slidably connected to the fifth slide rail 311 again; then, the end of the head protection plate 22 connected to the third slide rail 211 is controlled to slide to fit with the side of the head support tray 21 close to the neck protection plate 32, so as to protect the back of the patient's head, and then the other end of the head protection plate 22 is controlled to move from the back of the patient's head to the top of the head, and then from the top of the head to the patient's face, and at the same time, the excess part of the side of the head protection plate 22 is controlled to cover the patient's ears, and at the mouth and nose notch 2 After 21 is aligned with the patient's mouth and nose, the excess part of one end of the head protection plate 22 provided with the mouth and nose notch 221 is introduced between the neck protection plate 32 and the patient's neck, so that the head protection plate 22 and the neck protection plate 32 can jointly protect the patient's head and neck; at the same time, according to the needs of the examination, for the part of the patient that does not need to be examined, the body protection device 4 is controlled to be slidably connected with the second slide rail 12, and the body protection device 4 slides to a specified position, and then the lower connecting piece 422 is controlled to swing between them until the lower connecting piece 422 drives the lower lead glue layer 421 to cover the top surface of the bed body 1, and the lower connecting piece 422 is controlled to be connected with the upper lead glue layer 411 through the Velcro 45. After the part of the patient that does not need to be examined is aligned with the top surface of the lower lead glue layer 421, the upper connecting piece 412 is controlled to drive the upper lead glue layer 411 to move to the top surface of the part of the patient that does not need to be examined.
