Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a CT scanning head frame extension plate integrated device which is convenient for body position switching. Background Art

[0002] CT examination has fast imaging speed and wide application range. It can be used to examine all parts of the body. However, due to equipment reasons, when the examination bed rises to a certain height and enters a certain range, the examination bed body will no longer move, and the patient will be sent to the CT scanning frame through the movement of the bed board to complete the examination. Due to the limited scanning range of the examination bed and the height and weight of the examinee, the whole body examination is usually examined separately, because if the body position is not changed during an examination from head to toe, it will be a great test for the examination bed, and it also increases the risk of the examinee falling. Therefore, it is usually necessary to place and position the body in different positions according to the examination part. Conventional head and neck scans will use a head frame and adopt a head-first mode, and scans below the pelvis will use an extension board and adopt a foot-first mode. Both are possible for the body (chest and abdomen). When a patient needs to examine the head and neck and lower limbs at the same time, we usually need to replace the head frame and extension board, which is bound to bring a certain degree of inconvenience to the work, so there is an urgent need for a device that facilitates the patient's position switching. Utility Model Content

[0003] The utility model aims to provide a CT scanning head frame extension plate integrated device which is convenient for body position switching, and can realize the switching of patient body position without replacing the extension plate and the scanning head frame.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a CT scanning head frame extension plate integrated device that is convenient for body position switching, including a plug-in plate, an extension plate, a head support, a double-headed screw, and a U-shaped groove, wherein:

[0005] A threaded hole is provided at the center of one end of the plug-in board, one end of the double-headed screw is threadedly connected to the threaded hole, a main through hole is provided along the central axis of the extension plate, and the other end of the double-headed screw is fixed with a nut after passing through the main through hole, and the part of the double-headed screw located in the main through hole is a bare rod; the plug-in board is used to be inserted into a slot at one end of the bed board of the CT examination bed;

[0006] The head support is fixedly mounted at the middle position of the upper surface of the extension plate;

[0007] The extension plate is provided with a vertical through hole penetrating the upper and lower surfaces of the extension plate on both sides of the head support, and a through hole penetrating the two side walls is also provided at one end of the U-shaped groove, and a notch is provided at the bottom of the U-shaped groove opposite to the through hole;

[0008] The two U-shaped grooves are hingedly installed on both sides of the extension plate through pins installed in the vertical through holes of the extension plate and the through holes of the U-shaped grooves. The U-shaped grooves can rotate around the pins. When the U-shaped grooves are in the initial position, their openings are engaged with both sides of the extension plate, and the other end of the U-shaped grooves continues to extend a distance toward the plug-in board, and the extended part is used to engage with both sides of the bed board of the CT examination bed.

[0009] The notch at the bottom of the U-shaped groove ensures that when the U-shaped groove rotates outward around the pin axis, the bottom of the groove is not supported by the two sides of the extension plate, so that it can rotate smoothly.

[0010] The working mode and principle of the utility model are:

[0011] Since the portion of the double-headed screw located in the main through hole is a smooth rod, the extension plate can rotate 360 ​​degrees around the double-headed screw.

[0012] Insert the plug board into the slot at one end of the bed board of the CT examination bed. When the device of the utility model needs to be used as a headrest mode, just pull the U-shaped slot to both sides, rotate the extension plate to make the headrest upward, and then push the U-shaped slots on both sides inward so that the U-shaped slots can simultaneously clamp the two sides of the extension plate and the two sides of the bed board of the CT examination bed, and the device is fixed. The headrest is used to place the head of the examinee, and when the examinee undergoes a chest and abdominal examination, the examinee should raise both upper limbs above the head. When using this device, the examinee's upper limbs can be placed on the extension plates on both sides of the headrest, avoiding the discomfort caused by the upper limbs hanging in the air.

[0013] When the device of the utility model needs to be switched to the extension board mode, it is only necessary to open the U-shaped grooves to both sides again, rotate the extension board to make the head support downward, turn the lower surface of the extension board upward, and then push the U-shaped grooves on both sides inward so that the U-shaped grooves simultaneously clamp the two sides of the extension board and the two sides of the bed board of the CT examination bed, and the device is fixed. At this time, the extension board is used to place the distal part of the lower limbs of the examinee.

[0014] Furthermore, a groove is provided in the middle of the head support, so that the support for the subject's head is more stable.

[0015] Furthermore, the lower surface of the extension plate has a groove.

[0016] Furthermore, since the thickness on both sides of the extension plate may be inconsistent with the thickness on both sides of the bed board of the CT examination bed in actual use, the U-shaped groove is set to have two sections with different opening sizes, that is, the U-shaped groove is composed of a first sub-groove and a second sub-groove fixedly connected. When the U-shaped groove is in the initial position, the opening of the first sub-groove is engaged with the two sides of the extension plate, and its opening size is adapted to the thickness of the two sides of the extension plate. The opening of the second sub-groove is used to engage with the two sides of the bed board of the CT examination bed, and its opening size is adapted to the thickness of the two sides of the bed board of the CT examination bed.

[0017] The beneficial effects of the utility model are:

[0018] Since the extension plate can rotate 360 ​​degrees around the double-headed screw, the head frame mode and the extension plate mode can be switched quickly and easily during use; the clever use of a U-shaped groove that can rotate around a pin shaft allows the extension plate to be quickly fixed after rotation; and the U-shaped groove simultaneously engages both sides of the extension plate and both sides of the bed board of the CT examination bed, further enhancing the load-bearing capacity of the extension plate.
