Description

Technical Field

[0001] The present application relates to the technical field of bone age detection equipment, and in particular to a self-service detection type campus bone age meter. Background Art

[0002] Bone age testing is an important medical diagnostic method and is widely used in the field of pediatrics, especially in the endocrinology department, for the diagnosis of abnormal growth and development such as dwarfism and precocious puberty. In addition, it is also used in school health checks, athlete selection and other scenarios. By analyzing X-rays of children's hands, their skeletal maturity can be determined, which helps diagnose and monitor endocrine diseases and growth disorders in children. In addition, bone age testing is also an important reference for parents to understand their children's growth and development, especially when their children's height growth is slow, so that they can find problems in time and take corresponding measures.

[0003] However, when testing bone age, children need to completely fit the back of their hands and fingers to the X-ray imaging plate, with their five fingers spread out and their wrists flat on the X-ray imaging plate to obtain more accurate test results. Children have poor comprehension and expression abilities and tend to move around, so medical staff need to spend a lot of energy and time to guide children to make and maintain correct movements during bone age testing, which makes bone age testing less efficient and results in larger errors. Summary of the invention

[0004] In order to improve the efficiency of bone age detection for children, the present application provides a self-service detection type campus bone age meter.

[0005] This application provides a self-service detection campus bone age meter, which adopts the following technical solutions: A self-service detection type campus bone age meter, comprising: Mounting seat; The detection assembly comprises a detection chamber and an X-ray source, wherein the detection chamber has a detection port formed on the outer wall of the mounting seat, and the X-ray source is arranged inside the detection chamber; A positioning assembly, comprising an active roller, a driven roller, a first driving member and a plurality of imaging chain plates, wherein the active roller is rotatably arranged in the detection chamber and the rotation axis is arranged in the horizontal direction, the driven roller is arranged in parallel with the active roller and is rotatably arranged inside the detection chamber, the first driving member is used to drive the active roller to rotate, the plurality of imaging chain plates are rotatably connected in sequence, the plurality of imaging chain plates are wound around the active roller and the driven roller, the outer wall of the imaging chain plate is fixedly connected with a first Velcro, and when the active roller rotates, the active roller and the driven roller cooperate to drive the plurality of imaging chain plates to move around the active roller and the driven roller at the same time; The fixed glove has a second Velcro fixedly connected to one side of the back of the hand, and the first Velcro is used to bond and cooperate with the second Velcro to fix the fixed glove to the imaging chain plate.

[0006] By adopting the above technical solution, the active roller, the driven roller, the first driving member and a plurality of imaging chain plates form a chain plate conveyor belt, and the top wall of the chain plate conveyor belt forms a plane for X-ray imaging. During the test, the child wears fixed gloves, then separates the fingers, and the second Velcro near the fingertips is bonded with the first Velcro at the imaging chain plate of the driven roller or the active roller. The first driving member drives the chain plate conveyor belt to convey the child's hand, so that the second Velcro gradually and completely fits with the first Velcro on the chain plate conveyor belt, so that when the child's hand is located on the top wall of the chain plate conveyor belt, the back of the child's hand is completely fitted with the top wall of the chain plate conveyor belt, and the first Velcro and the second Velcro can fix the child's hand, thereby reducing the energy and time spent by medical staff in guiding children, and improving the efficiency and accuracy of bone age detection.

[0007] Optionally, a guide rail is arranged between the active roller and the driven roller, and the guide rail is slidably connected to a vertical rod. A second driving member is arranged inside the detection chamber, and the output end of the second driving member moves in a horizontal direction, and the output end of the second driving member is fixedly connected to the vertical rod. When the vertical rod moves, the active roller rotates around the driven roller, and the X-light source is rotatably connected to the inner wall of the detection chamber.

[0008] By adopting the above technical solution, when the child's hand is transported to the top wall of the chain plate conveyor belt, the child's wrist may be tilted, resulting in inaccurate X-ray imaging. When the child's wrist is tilted, the vertical rod moves to adjust the height of the active roller so that the line connecting the rotation axis of the active roller and the rotation axis of the driven roller is parallel to the child's arm, so that the child's wrist fits the top wall of the chain plate conveyor belt, and the X-ray light source rotates to face the top wall of the chain plate conveyor belt, so as to improve the accuracy of X-ray imaging, thereby improving the accuracy of bone age detection.

[0009] Optionally, the positioning assembly includes a positioning column group, the positioning column group includes four positioning columns arranged at intervals, and the positioning columns are used to abut against the child's finger webs to separate adjacent fingers of the child.

[0010] By adopting the above technical solution, the positioning column corresponds to the finger web of a hand one by one. When a child adheres the second Velcro to the first Velcro, the adjacent fingers are separated by first making the finger web abut against the positioning column, and then the second Velcro is adhered to the first Velcro, thereby reducing the situation of finger adhesion during X-ray imaging and improving the accuracy of bone age detection.

[0015] Optionally, the spacing between adjacent positioning columns of the positioning column group corresponds to the height of the detection component in which the positioning column group is located. The lower the height of the detection component, the smaller the spacing between adjacent positioning columns of the corresponding positioning column group.

[0016] By adopting the above technical solution, children with shorter height generally have smaller hands. The lower the height of the detection component, the smaller the distance between adjacent positioning columns, so that the lower detection component can better adapt to children with smaller hands.

[0017] Optionally, the imaging chain plate is provided with a slide groove in a direction perpendicular to the imaging chain plate, the positioning column is slidably connected to the inner wall of the slide groove along the length direction of the slide groove, and an elastic member is connected between the positioning column and the inner wall of the slide groove.

[0018] By adopting the above technical solution, when the child's arm is in contact with the imaging chain plate, the arm presses the positioning column into the slide groove, thereby improving the child's comfort and reducing the situation where the child twists his arm due to discomfort, thereby improving the accuracy of the detection results.

[0019] Optionally, the mounting seat is provided with a protective curtain, and the protective curtain is used to open and close the detection port.

[0020] By adopting the above technical solution, the protective curtain can reduce the dust entering the detection room.

[0022] By adopting the above technical solution, medical staff can observe the position of children's palms and arms through the monitoring component, and guide children to change their postures when their palms and arms are not placed properly, thereby improving the detection efficiency and the accuracy of the detection results.

[0023] In summary, the present application includes at least one of the following beneficial effects: 1.

[0026] Bone age testing is widely used in the field of pediatrics. By analyzing X-rays of children's hands, their skeletal maturity can be determined, which helps diagnose and detect children's endocrine diseases and growth disorders. It is used to diagnose growth and development abnormalities such as dwarfism and precocious puberty. It is also an important reference for understanding children's growth and development status, and is often used when children's height growth is slow.

[0027] When doing a bone age examination, the back of the child's hand needs to be completely in contact with the X-ray imaging plate, with the palm facing the X-ray light source 23, the five fingers separated from each other, and the wrist parallel to the X-ray imaging plate. However, children's comprehension, expression and self-control abilities are relatively poor, resulting in medical staff spending a lot of energy and time to guide children to make and maintain standard movements.

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] The present application discloses a self-service detection type campus bone age meter, referring to Figure 1 and Figure 2 The self-service detection campus bone age meter includes a mounting base 1, a monitoring component 4 and three detection components 2 staggered in the vertical direction.

[0030] Reference Figure 3 The detection assembly 2 includes a detection chamber 21 and an X-ray source 23. The detection chamber 21 is arranged inside the mounting seat 1. The detection chamber 21 is formed with a detection port 22 on the outer wall of the mounting seat 1. The three detection ports 22 are arranged one by one on the three side walls of the mounting seat 1. The mounting seat 1 at the detection port 22 is fixedly connected with a protective curtain 5, and the protective curtain 5 can cover the detection port 22. A positioning assembly 3 for positioning and fixing the palm and arm of the child is arranged inside the detection chamber 21. The X-ray source 23 is arranged inside the detection chamber 21 and is connected to the top wall of the detection chamber 21 through a motor rotation.

[0031] Reference Figure 1 and Figure 3The monitoring component 4 includes an electrically connected display screen 42 and three cameras 41. The display screen 42 is fixedly connected to the side wall of the mounting base 1 where the detection port 22 is not opened. The cameras 41 correspond to the detection rooms 21 one by one. The cameras 41 are arranged inside the corresponding detection rooms 21 and are fixedly connected to the inner wall of the detection room 21. The X-ray light source 23 is an X-ray tube.

[0032] The child extends his palm and arm through the detection port 22 into the detection chamber 21 for bone age detection. Multiple detection components 2 can simultaneously detect the bone age of multiple children, further improving the efficiency of bone age detection. The detection components 2 are staggered in the vertical direction, so that the bone age instrument can detect children of different heights and allow children to choose a more comfortable posture for detection, thereby reducing the situation where children move around due to discomfort during the detection. The camera 41 captures the palm and arm of the child, and the medical staff can observe the posture of the child's palm and arm through the display screen 42, so as to guide the child to adjust the posture in time, thereby further improving the efficiency and accuracy of bone age detection.

[0033] The protective curtain 5 can reduce dust and flying debris entering the detection chamber 21 .

[0034] Reference Figure 3 and Figure 4The positioning assembly 3 includes an active roller 32, a driven roller 33, a first driving member 34, a second driving member 38 and a plurality of imaging chain plates 35. The second driving member 38 is a linear motor. The second driving member 38 is installed on the bottom wall of the detection chamber 21. The moving direction of the output end of the second driving member 38 is in the horizontal plane toward the detection port 22. The output end of the second driving member 38 is fixedly connected to a vertical rod 37 arranged in the vertical direction. The end of the vertical rod 37 away from the second driving member 38 is slidably connected to a guide rail 36. The guide rail 3 6 is rotatably connected to the active roller 32 at one end, and the rotation axis of the active roller 32 is arranged in the horizontal direction. The other end of the guide rail 36 is rotatably connected to the driven roller 33, and the rotation axis of the driven roller 33 is arranged in the horizontal direction. The driven roller 33 is rotatably connected to the inner wall of the detection chamber 21, so that the active roller 32 can rotate while rotating around the driven roller 33. The first driving member 34 is fixedly connected to the guide rail 36, and the output end of the first driving member 34 is coaxially fixedly connected to the active roller 32. The first driving member 34 is a motor. Multiple imaging chain plates 35 are rotatably connected in sequence to form a ring, and multiple imaging chain plates 35 are wound around the active roller 32 and the driven roller 33, so that the active roller 32, the driven roller 33, the first driving member 34, the guide rail 36 and the multiple imaging chain plates 35 form a chain plate conveyor belt. The conveying direction of the conveyor belt is the connecting direction of the multiple imaging chain plates 35. The driven roller 33 is arranged at one end of the chain plate conveyor belt close to the detection port 22. The material of the imaging chain plate 35 is polyethylene terephthalate and the surface of the imaging chain plate 35 is coated with fluorescent powder, so that the imaging chain plate 35 can absorb X-rays and emit visible light, so that the imaging chain plate 35 can store image information under the irradiation of X-rays and convert it into a visual digital image through a subsequent reading process.

[0035] The outer wall of the imaging chain plate 35 is bonded with a first Velcro, which is the fur surface of the Velcro and is not shown in the drawings.

[0036] The self-service detection campus bone age instrument comprises a fixed glove, which is a full-finger glove made of cotton. The outer wall of the fixed glove is bonded with a second Velcro, which covers one side of the back of the fixed glove, and the second Velcro is a thorny side of the Velcro.

[0037] Reference Figure 3 and Figure 4 A plurality of imaging chain plates 35 form a plane used as an X-ray imaging plate on the top wall of the chain plate conveyor belt, and the plurality of imaging chain plates 35 abutting against the driven roller 33 form an arc surface, which is connected to one end of the plane close to the detection port 22.

[0038] Before taking an X-ray, the child puts on a fixed glove, then spreads the five fingers apart, and adheres the second Velcro near the fingertips to the first Velcro at the connection between the arc surface and the plane or at the end of the arc surface close to the plane. The child then relaxes his arms, and places the palm and arm on the chain conveyor under the action of gravity. The first driving member 34 drives the chain conveyor to transport the palm with the fixed glove toward the direction close to the active roller 32 to below the X-ray source 23. During the transportation process, the second Velcro gradually and completely adheres to the multiple first Velcro on the chain conveyor, so that the back of the child's hand is completely in contact with the plane used as the X-ray imaging plate, and the child's fingers are in a separated state. If at this time, the child's wrist is tilted relative to the plane, the second driving member 38 drives the vertical rod 37 to move in the horizontal direction, so that the active roller 32 rotates around the driven roller 33, so that the plane used as the X-ray imaging plate rotates to be parallel to the child's arm, so that the child's arm and the back of the hand are both in contact with the plane used as the X-ray imaging plate, so that the child's wrist is in contact with the plane used as the X-ray imaging plate, and the X-ray light source 23 needs to be rotated to face the plane used as the X-ray imaging plate. In this way, the child's fingers, back of the hand and wrist can be placed according to the requirements of the bone age test, thereby improving the efficiency of the bone age test and the accuracy of the bone age test results. The first Velcro is combined with the second Velcro to fix the child's fingers and back of the hand on the plane used as the X-ray imaging plate, reducing the situation where the child's movement causes the accuracy of the bone age test results to decrease.

[0039] When the second driving member 38 drives the vertical rod 37 to move toward the active roller 32, the active roller 32 rotates clockwise around the driven roller 33, so that the plane used as the X-ray imaging plate rotates clockwise around the driven roller 33. When the second driving member 38 drives the vertical rod 37 to move away from the active roller 32, the active roller 32 rotates counterclockwise around the driven roller 33, so that the plane used as the X-ray imaging plate rotates counterclockwise around the driven roller 33.

[0040] Reference Figure 5The chain plate conveyor belt is provided with a plurality of positioning column groups 39 at intervals along the connecting direction of the plurality of imaging chain plates 35. The positioning column group 39 includes four positioning columns 310. The positioning columns 310 correspond to the webs of a single palm one by one. The imaging chain plates 35 are provided with slide grooves 311 corresponding to the positioning columns 310. The slide grooves 311 are arranged in a direction perpendicular to the imaging chain plates 35. The positioning columns 310 are slidably connected to the inner wall of the slide groove 311 along the length direction of the slide groove 311. One end of the positioning column 310 passes through the slide groove 311. An elastic member 312 is connected between the positioning column 310 and the bottom wall of the slide groove 311. The elastic member 312 is a spring. The spacing between adjacent positioning columns 310 of different positioning column groups 39 on the same chain plate conveyor belt gradually decreases along the connecting direction of the plurality of imaging chain plates 35. Furthermore, the spacing between adjacent positioning posts 310 of the positioning post group 39 corresponds to the height of the detection assembly 2 in which the positioning posts 310 are located. The lower the height of the detection assembly 2 is, the smaller the spacing between adjacent positioning posts 310 of the corresponding positioning post group 39 is.

[0041] Before the first Velcro and the second Velcro are bonded together, the child first abuts the webbed fingers of the palm against the corresponding positioning post 310, and then the first Velcro and the second Velcro are bonded together, which can improve the accuracy of palm positioning. The multiple positioning post groups 39 with different spacings between the positioning posts 310 on the same chain plate conveyor belt can make the bone age instrument adapt to children with different hand shapes and palm sizes, increasing the applicability of the bone age instrument. Children with shorter heights generally have smaller hands. The lower the height of the detection component 2, the smaller the spacing between adjacent positioning posts 310, so that the detection component 2 with a lower position can better adapt to children with smaller hands.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
