Description

Technical Field

[0001] The utility model relates to the technical field of CT scanning, in particular to a positioning auxiliary device for CT scanning of inner ear of children. Background Art

[0002] For children's inner ear CT scans, the challenges are not only their young age and low cooperation ability, but also their relatively small and complex anatomical structures. Usually, children need to lie on their backs and stabilize their heads in a camera headrest to ensure the accuracy and clarity of the image. However, since the two external ear holes of children are located on both sides of the skull and are narrower than those of adults, there are certain difficulties and time-consuming in the positioning process.

[0003] In traditional CT scans, locating the external ear opening usually requires relying on the infrared positioning light built into the medical device. These positioning systems use infrared light to help doctors accurately determine the position of the child's external ear opening and place it on the same horizontal line to ensure the accuracy of the scan. However, although these technologies are quite mature, there are still some challenges. For example, pediatric patients usually have poor collaboration skills, and they may not be able to fully cooperate with the medical staff's operational requirements, making the positioning process more complicated, requiring medical staff to constantly adjust and calibrate, increasing the time and difficulty of positioning. Child patients are anxious and uneasy about the medical process, which may lead to their non-cooperation or unstable movements when undergoing CT scans, which in turn affects the accuracy and efficiency of positioning.

[0047] The following describes in detail the children's inner ear CT scanning positioning auxiliary device according to an embodiment of the utility model with reference to the accompanying drawings.

[0048] Reference Figures 1 to 3 As shown, the positioning auxiliary device for inner ear CT scanning of children provided according to an embodiment of the utility model includes a positioning plate 10 and two supporting legs 20.

[0049] Specifically, the top surface of the positioning plate 10 is provided with a first reference line 101 and a second reference line 102 , the first reference line 101 extends along the length direction of the positioning plate 10 , and the second reference line 102 intersects the first reference line 101 perpendicularly and is located in the middle of the length direction of the positioning plate 10 .

[0050] The first reference line 101 and the second reference line 102 are designed to correspond to the infrared light on the machine during the CT scanning process, so as to achieve accurate head position positioning, wherein the first reference line 101 is used to align with the transverse infrared light released by the CT machine to ensure accurate positioning of the transverse axis of the patient's head. The second reference line 102 is used to align with the longitudinal infrared light released by the CT machine to determine the sagittal position of the patient's head.

[0051] In order to ensure the support of the positioning plate 10, the positioning plate 10 is usually made of plastic or metal with high structural strength, such as acrylic, aluminum alloy, etc., and is also easy to clean and disinfect. The surface of the positioning plate 10 may be treated with antibacterial materials to reduce the risk of cross infection.

[0052] The upper end of one of the two legs 20 is connected to one end of the positioning plate 10 in the length direction, and the upper end of the other of the two legs 20 is connected to the other end of the positioning plate 10 in the length direction. The lower end of each leg 20 is provided with an earplug portion 2023 suitable for inserting into the external ear hole. The two legs 20 are symmetrically arranged about the second reference line 102, and the two legs 20 and the first reference line 101 are on the same transverse section, and the second reference line 102 is perpendicular to the transverse section.

[0053] That is, the upper end of each leg 20 is fixed to the two ends of the positioning plate 10 to form a stable support structure. This layout allows the positioning plate 10 to span the child's head while maintaining balance and symmetry. The earplug portion 2023 is used to plug into the child's external ear canal to contact. Generally, the earplug portion 2023 is made of soft material and has a shape that can easily adapt to the contour of the ear canal.

[0054] The two legs 20 are arranged symmetrically about the second reference line 102, the first reference line 101 and the legs 20 are on the same transverse section, and the second reference line 102 is perpendicular to the transverse section and arranged in the center. This ensures that after the earplug part 2023 is inserted into the external ear holes of the child, the two external ear holes are on the transverse section. During the positioning process, the medical staff can quickly and accurately complete the head positioning by adjusting the head position of the child and / or the positioning board 10 so that the first reference line 101 and the second reference line 102 are aligned with the infrared rays of the CT machine.

[0055] The following briefly describes the use of the children's inner ear CT scanning positioning auxiliary device.

[0056] Preparation: The child lies on the CT scanning bed, and the medical staff places the positioning plate 10 above the child's head and adjusts it to a suitable position to ensure that the first reference line 101 and the second reference line 102 of the positioning plate 10 are clearly visible. Gently insert the earplug parts 2023 at the lower ends of the two legs 20 into the child's external ear holes.

[0057] Adjustment and alignment: The medical staff adjusts the positioning plate 10 and / or the patient's body position so that the first reference line 101 coincides with the horizontal infrared light emitted by the CT machine, and the second reference line 102 coincides with the vertical infrared light. This step is the key to ensure accurate head positioning.

[0058] Confirming positioning: Once positioning is confirmed, the healthcare provider will check the child's comfort, remove the positioning aid, and ensure they remain still during the scan.

[0059] Start the scan: Once everything is ready, the medical staff will start the CT scan. During the scan, the medical staff will closely monitor the child's condition and the operation of the scanning equipment.

[0060] According to the child inner ear CT scanning positioning auxiliary device provided by the embodiment of the utility model, the earplug part 2023 on the two legs 20 can be inserted into the child's external ear hole to keep the positioning plate 10 above the child's face. Since the two legs 20 and the first reference line 101 are on the same transverse section, and the second reference line 102 is perpendicular to the transverse section and centered, during the positioning process, it is only necessary to ensure that the first reference line 101 coincides with the transverse infrared light released on the machine equipment, and the second reference line 102 coincides with the longitudinal infrared light released on the machine equipment, so that the head position can be accurately positioned, which can improve the positioning efficiency and positioning accuracy, has a simple structure, and is easy to operate. In addition, after the positioning is completed, the auxiliary positioning device can be removed, which has no effect on the image quality during the scanning inspection and does not affect the disease diagnosis.

[0061] In some embodiments of the present invention, the support leg 20 is configured as a retractable structure to adjust the length of the support leg 20. Before use, the medical staff will adjust the length of the support leg 20 according to the size of the child's head, so that after the ear plug portion 2023 on the support leg 20 is inserted into the external ear hole of the child, the positioning plate 10 remains above the face of the child.

[0062] In this embodiment, the positioning auxiliary device can adapt to each child patient and achieve better adaptability through the design of the retractable support foot 20.

[0063] In one embodiment of the utility model, the support foot 20 includes a ruler rod 201 and a sleeve rod 202, the upper end of the ruler rod 201 is connected to one end of the positioning plate 10, and the outer side of the ruler rod 201 is provided with a scale mark, and the scale mark includes a plurality of scale lines arranged in sequence along the length direction of the ruler rod 201. The sleeve rod 202 is sleeved on the lower end of the ruler rod 201 and can slide relative to the ruler rod 201 along the length direction of the ruler rod 201, and the earplug part 2023 is provided at the lower end of the sleeve rod 202 and protrudes inward.

[0064] That is, the support leg 20 is mainly composed of a ruler rod 201 and a sleeve rod 202, and the upper end of the ruler rod 201 is connected to the positioning plate 10. The outer side of the ruler rod 201 is provided with scale marks, which are a series of scale marks arranged in sequence along the length direction of the ruler rod 201. These scale marks provide a visual reference for medical staff so that they can accurately adjust the length of the support leg 20.

[0065] The sleeve rod 202 is sleeved on the lower end of the ruler rod 201 and can slide along the length direction of the ruler rod 201. This design allows medical staff to adjust the length of the support leg 20 according to the size of the child's head to ensure that the earplug part 2023 can be correctly inserted into the external ear canal. The earplug part 2023 is located at the lower end of the sleeve rod 202 and protrudes inward, which helps the earplug part 2023 better fit the child's ear canal and also allows the earplug part 2023 to be stably maintained in the external ear canal.

[0066] In this embodiment, the positioning auxiliary device can adapt to children of different ages and sizes through the design of adjustable legs 20, thereby improving the accuracy and comfort of positioning. During the CT scanning process, medical staff can quickly and accurately adjust the length of the legs 20 to ensure that the positioning plate 10 is correctly located above the child's head, thereby improving the efficiency and quality of the scan.

[0067] In one embodiment of the utility model, a boss 2021 is provided on the outer side of the sleeve rod 202, and a first threaded hole extending inward is provided on the boss 2021. A first ball-shaped screw 2022 is provided in the first threaded hole, and the ball-shaped end of the first ball-shaped screw 2022 is elastically supported on the ruler rod 201.

[0068] The first ball screw 2022 is a set screw having a ball end for providing an elastic supporting force. The ball end of the first ball screw 2022 is configured to be elastically supported on the ruler rod 201. This elastic support can provide a reliable fixing method while also allowing a certain degree of flexibility and adjustment. The elastic support between the ball end and the ruler rod 201 requires a large resistance to be overcome when the sleeve rod 202 and the ruler rod 201 slide relative to each other. Therefore, when adjusting, it is necessary to pull the ruler rod 201 or the sleeve rod 202 with a little force, and after loosening, the elastic support can be used to keep the ruler rod 201 and the sleeve rod 202 relatively fixed without loosening or sliding.

[0069] In this embodiment, the advantage of using this first ball screw 2022 is that it can provide a stable and flexible adjustable method, and the support foot 20 can better adapt to different length adjustment needs, thereby improving the overall convenience and reliability of use.

[0070] In some embodiments of the utility model, the upper end of the ruler 201 is bent inward to form a horizontal slide bar 2011. Both ends of the positioning plate 10 are provided with slide holes H10, which extend along the length direction of the positioning plate 10. The two legs 20 correspond to the two slide holes H10 one by one. The horizontal slide bar 2011 on each leg 20 is inserted into the corresponding slide hole H10 and can slide along the length direction of the positioning plate 10, thereby achieving an adjustable spacing between the two to accommodate different children.

[0071] In this embodiment, the upper end of the ruler 201 is bent inward to form a horizontal slide bar 2011, and the horizontal slide bar 2011 is slidably matched with the slide hole H10 at the end of the positioning plate 10. This design allows the support legs 20 to slide along the length direction on the positioning plate 10, thereby adjusting the distance between the two support legs 20. During use, medical staff can adjust the distance between the two support legs 20 according to the size of the child's head. This design enables the positioning auxiliary device to adapt to children of different ages and head sizes, and can meet the needs of various clinical situations. In addition, the operation is simple, and medical staff can quickly adjust the distance between the support legs 20 without replacing devices of different sizes, thereby improving work efficiency.

[0072] In one embodiment of the present invention, two second threaded holes are provided on the bottom surface of the positioning plate 10 , and the two second threaded holes correspond to the two sliding holes H10 one by one, and each of the second threaded holes penetrates upward to the corresponding sliding hole H10 .

[0073] A second ball-end screw 11 is disposed in each of the second threaded holes, and a ball-end end of the second ball-end screw 11 elastically abuts against the corresponding horizontal slide bar 2011 .

[0074] In this embodiment, the elastic abutment between the ball end of the second ball screw 11 and the horizontal slide bar 2011 can ensure that the horizontal slide bar 2011 can slide freely in the slide hole H10 to adjust the position of the support leg 20. At the same time, after adjusting to the appropriate position, the ball end of the second ball screw 11 abuts against the horizontal slide bar 2011, so that the horizontal slide bar 2011 remains in this position. In this way, medical staff can adjust the spacing of the support legs 20 according to the size of the child's head, and the horizontal slide bar 2011 will not move after the adjustment is completed. This design not only provides convenient and simple adjustability to adapt to children of different sizes, but also ensures the stability of the support legs 20 after adjustment.

[0075] Preferably, an isolation pad 103 is attached to the bottom surface of the positioning plate 10. The isolation pad 103 is made of soft rubber material, which usually has good elasticity and softness and can provide better cushioning and comfort. The isolation pad 103 can provide a soft support surface for the child's head, reducing the discomfort that may be caused by the hard positioning plate 10 directly contacting the skin.

[0076] Preferably, the surface of the earplug part 2023 is covered with a soft rubber cover, so that the comfort of use can be improved.
