[0034] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0035] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0036] Reference Figure 1-6 This embodiment provides an infant auxiliary device for CT imaging examination, comprising:

[0037] The base 1 has two side panels 11 arranged opposite to each other. The two side panels 11 can rotate 90 degrees relative to each other by setting a flip structure 12. The flip structure 12 is provided with an elastic connecting rod structure 13 for extending / retracting the side panels 11.

[0038] The base 1 also has two sets of symmetrically arranged limit plates 14, which are clamped on both sides of the CT examination bed to prevent the base 1 from shaking;

[0039] The limiting plate 14 is an "L"-shaped structure. When an infant comes for examination, the medical staff holds the base 1 and places it on the CT examination bed. When placing it, it is necessary to ensure that the two sets of limiting plates 14 are respectively attached to the outer side of the CT examination bed and downward until the bottom of the base 1 is attached to the upper surface of the CT examination bed. At this time, the limiting plate 14 limits the movement of the base 1 to prevent the infant from twisting and falling while lying on the base 1;

[0040] The base 1 is made of plastic material, which is light and easy for medical staff to pick up. When a sideways examination is required, the infant is laid on its side in the middle of the base 1, and the flip structure 12 is used to drive the two side uprights 11 to rotate 90° relative to each other, forming two vertically arranged limiting walls. The infant is clamped in the middle by the two limiting walls, which can ensure the side-lying state of the infant, avoiding the problem of misdiagnosis or invalid examination due to movement during the examination;

[0041] The elastic connecting rod structure 13 drives the side upright plate 11 to move horizontally in a vertical state to approach the back / abdomen of the infant. This structure can meet the needs of infants of different body shapes and is easy and flexible to use, and has high practicality.

[0042] The shielding part 2 is composed of a plurality of strips of lead cloth and covers the human body to block radiation.

[0043] Embedding grooves are provided on the upper surface of the base 1 at positions corresponding to the two side upright plates 11 , and the two side upright plates 11 are embedded in the embedding grooves.

[0044] The flip structure 12 includes an elastic rotating component 121;

[0045] The elastic rotating assembly 121 has a rotation angle of 0-90°, and is used to drive the side stand 11 to change between horizontal and vertical directions.

[0046] Specifically, the elastic rotating component 121 includes a support plate 1211, one end of which rotates in the embedding groove through a rotating shaft 1212, and a torsion spring 1213 is sleeved on the rotating shaft 1212. The two force angles of the torsion spring 1213 are distributed at 180° when no force is applied. One end of the torsion spring 1213 is fixed vertically downward at the bottom of the embedding groove, and the other end is embedded in the bottom of the support plate 1211. When the side plate 11 is in a horizontal state, the angle between the two force angles of the torsion spring 1213 is 90°, and the torsion spring 1213 stores force at this time. When the side plate 11 is in a vertical state, the angle between the two force angles of the torsion spring 1213 is 180°, and the torsion spring 1213 does not store force.

[0047] The flip structure 12 also includes a locking assembly 122;

[0048] The locking assembly 122 includes a lock core and a lock tongue. The lock core is disposed below one end of the side stand 11, and the lock tongue is disposed in the embedding groove.

[0049] The locking tongue member abuts against the lock core member to limit the horizontal state of the side stand 11 .

[0050] Specifically, the lock core member includes a guide column 1221, a fixed block 1222 is provided at the bottom of the guide column 1221, and a movable sleeve 1223 is sleeved on the guide column 1221, the cross-sections of the fixed block 1222 and the movable sleeve 1223 are both conical structures, the conical structure has an inclined surface and a plane, the plane of the fixed block 1222 faces upward, the plane of the movable sleeve 1223 faces downward and fits with the plane of the fixed block 1222, and the plane diameter of the movable sleeve 1223 is larger than the plane diameter of the fixed block 1222;

[0051] The locking tongue member includes a locking block 1224, which is installed in the embedded groove through a telescopic rod 1225. The locking block 1224 adopts a trapezoidal structure, with its inclined surface facing upward and toward one side of the lock core member;

[0052] When locking, press one side of the side plate 11 with your hand, the side plate 11 is stressed and transmits the force to the supporting plate 1211. After the supporting plate 1211 is stressed, it will rotate along the rotating shaft 1212 as a fulcrum. At this time, the side plate 11 will be converted from a vertical state to a horizontal state. When it is close to the horizontal state, the bottom inclined surface of the fixing block 1222 will touch the inclined surface of the upper surface of the locking block 1224. After the inclined surface of the locking block 1224 is squeezed, the vertical force will be converted into a horizontal force, and the horizontal force will be transmitted to the telescopic rod 1225. The telescopic rod 1225 is forced to retract and drive the locking block 1224 to retreat until the end of the locking block 1224 fits the outer edge of the fixing block 1222 and moves upward, and squeezes into between the fixing block 1222 and the movable sleeve 1223. At this time, the bottom of the locking block 1224 fits the plane of the fixing block 1222, thereby limiting the side plate 11 from being bounced open by the stored force of the torsion spring 1213;

[0053] When it is necessary to open, the side plate 11 is pressed again. At this time, the side plate 11 continues to move downward, and the inclined surface of the locking block 1224 will contact the lower edge of the movable sleeve 1223. The limit ring on the guide column 1211 is used to limit the movable height of the movable sleeve 1223. Therefore, the locking block 1224 will retract again through the telescopic rod 1225 until it fits on the inclined surface of the movable sleeve 1223. At this time, the pressing hand is released, and the stored force of the torsion spring 1213 will instantly drive the side plate 11 to flip upward. During the flipping process, the locking block 1224 slides downward along the inclined surface of the movable sleeve 1223 until it fits on its outer edge. Since the plane diameter of the fixed block 1222 is smaller than the diameter of the movable sleeve 1223, it can be directly disengaged to complete the unlocking. Under the action of the torsion spring 1213, a 90° flip is achieved;

[0054] The structure is very convenient to operate. It can be used and collected by just pressing, without too much operation. It shortens the operation time to the greatest extent, reduces the labor intensity of medical staff, and also improves the inspection efficiency, avoiding affecting the subsequent patient inspections.

[0055] The elastic connecting rod structure 13 includes a connecting rod member 131 and a tension member 132;

[0056] The tension member 132 pushes the connecting rod member 131 to drive the side stand 11 away from / close to the elastic rotating assembly 121 .

[0057] Specifically, the connecting rod 131 includes two cross-arranged connecting rods 1311, the middle ends of the two connecting rods 1311 are rotatably connected, and one of the same side ends of the two connecting rods is rotatably connected to a first rotating seat 1312, and the other same side ends are rotatably connected to a second rotating seat 1313, the two first rotating seats 1312 are respectively fixed to the support plate 1211 and the side stand 11, and the two second rotating seats 1313 are respectively slidably arranged on the support plate 1211 and the side stand 11, and the support plate 1211 is A slide groove is provided at the position of the two second rotating seats 1313, and the second rotating seats 1313 slide linearly in the slide groove. When the two second rotating seats 1313 are close to the first rotating seat 1312, the two connecting rods 1311 are in an "X" shape, and the side stand 11 is away from the support plate 1211, thereby achieving an extension effect; when the two second rotating seats 1313 are away from the first rotating seat 1312, the two connecting rods 1311 are in a nearly parallel state, and the side stand 11 is close to the support plate 1211, thereby achieving a retraction effect;

[0058] The tension member 132 comprises a fixed rod 1321 connecting the two second rotating seats 1313, a guide rod 1323 is provided on the fixed rod 1321, both ends of the guide rod 1323 are fixed to the support plate 1211 through the fixed seat 1323, a tension spring 1324 is sleeved on the guide rod 1323, both ends of the tension spring 1324 are respectively fixedly connected to the fixed seat 1323 and the fixed rod 1321, when the two second rotating seats 1313 are away from the first rotating seat 1312, the tension spring 1324 is stretched and is in a force storage state, at this time, the tension spring 1324 releases the stored force to drive the second rotating seat 1313 to approach the first rotating seat 1312, and the side stand 11 can be extended, and after the extension, it can fit the back / abdomen of the infant, thereby maximizing the restriction effect;

[0059] The structure is easy to operate and highly practical, and can meet the needs of infants and young children of different body shapes.

[0062] Specifically, the restraint components 3 are provided with four pieces, which are used to restrain the limbs of the infant, and include a patch 31, and a strap 31 is provided on the patch 31, and the strap 31 is tied to the limbs of the infant, thereby playing a restraining role to prevent the infant from moving around and affecting the examination;

[0063] The bottom of the patch 1 31 is provided with a Velcro hook surface, and the upper surface of the base 1 is provided with a Velcro velvet surface. The patch 31 can be bonded to any part, and has a flexible positioning effect;

[0064] A support assembly 4 is provided on the base 1, and the support assembly 4 is used to support the lead cloth to avoid compressing the injured part of the patient.

[0065] Specifically, the support component 4 includes a patch 41, and an arc-shaped arch block 42 is arranged on the patch 41. The arc-shaped arch block 42 can play a supporting role. When an infant or child is injured, the patch 41 can be placed on one side of the wound. At this time, the lead cloth is placed on the arc-shaped arch block 42 to play a supporting role and avoid the problem of secondary injury caused by direct pressure on the wound.

[0066] As an optional embodiment:
