Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a positioning auxiliary device for children's examination in a radiology department. Background Art

[0002] The radiology department is an important auxiliary examination department in the hospital. It integrates examination, diagnosis and treatment, and is of great significance for the clear diagnosis and auxiliary diagnosis of many diseases in various clinical departments. Children often face some special challenges when undergoing radiological examinations. First of all, children are naturally active and it is difficult for them to remain still for a long time, which will bring certain difficulties to the examination.

[0003] There are some shortcomings in the existing radiology auxiliary devices for children's examination. Some devices are not flexible enough when fixing children, and it is difficult to adjust according to the body shape and examination needs of different children.

[0004] In summary, how to solve the problem of insufficient flexibility when fixing children and difficulty in adjusting according to the body shape and examination needs of different children has become a technical problem that technicians in this field need to solve urgently. Therefore, it is necessary to propose a radiology child examination positioning auxiliary device. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a radiology child examination positioning auxiliary equipment. By setting a slide rail, a limb fixing component and an electric telescopic rod, the limb fixing component can adjust the corresponding distance according to the different body shapes and examination requirements of the children to achieve the function of fixing children of different body shapes on the examination table, so that the children can remain still for a long time.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a radiology child examination positioning auxiliary equipment, including an examination table and a controller, a plurality of brackets are fixedly connected to the examination table, a slide rail is fixedly connected between two opposite brackets on the length direction side, a plurality of sliders are slidably matched on the slide rail, the sliders and the slide rails are rotatably matched, a plurality of electric telescopic rods are fixedly connected to one side of the slider, the electric telescopic rods are electrically connected to the controller, and the controller is used to drive the output shaft of the electric telescopic rod to extend and retract; a limb fixing assembly for fixing the child's limbs is provided at one end of the electric telescopic rod away from the slider; a head fixing assembly for fixing the child's head is provided on the examination table; a positioning assembly for positioning the child's limbs is provided on one side of the examination table.

[0007] The technical principle of the above scheme is as follows: when examining a child, the child is made to lie on the examination table, and the head fixing assembly is used to fix the child's head. The medical staff slides the slider on the slide rail to the position of the child's limbs, and uses an electric telescopic rod to extend the limb fixing assembly to the appropriate position of the child's limbs. The limb fixing assembly on the slider is used to fix the child's limbs. At the same time, the positioning assembly can use big data to analyze the most suitable fixed position of the child's limbs, and remind medical staff to assist them in accurately positioning the child's limbs.

[0008] The above scheme has the following beneficial effects:

[0009] 1. This solution can accurately and firmly fix the child's head and limbs by designing a head fixing component and a limb fixing component. The head fixing component can prevent the child's head from shaking left and right; the limb fixing component uses the inflation mechanism of the airbag to achieve a soft and effective fixation of the child's limbs, which not only ensures the stability of the fixation, but also avoids the discomfort that may be caused by traditional fixation methods, and at the same time achieves adaptation to children of different sizes of limbs. This design enables the device to flexibly cope with children of different ages and body shapes, improving the versatility and practicality of the device.

[0010] 2. This solution introduces a controller for centralized control. Medical staff only need to operate the controller to fix the child's head and limbs. This further simplifies the operation process and improves work efficiency. The device uses airbag inflation to fix the child, which is gentler and safer than the traditional mechanical fixation method, and can effectively avoid unnecessary harm to the child. At the same time, the device is also equipped with a positioning component to help medical staff more accurately locate the child's body parts and ensure the accuracy of the examination.

[0011] 3. Since the equipment can accurately and firmly fix the child's body parts, it can greatly reduce the blurred images caused by the child's body movement during radiological examinations, and improve the clarity and accuracy of the examination. At the same time, the automated operation of the equipment also reduces the workload of medical staff and improves work efficiency.

[0012] Furthermore, the limb fixing assembly includes an arc-shaped bottom plate, a motor seat is fixedly connected to the bottom of the arc-shaped bottom plate, a stepper motor is fixedly connected to the motor seat, the stepper motor is electrically connected to a controller, and the controller is used to drive the stepper motor to rotate forward and reverse; a plurality of first fixing blocks are fixedly connected to a side wall of the arc-shaped bottom plate close to the stepper motor, the first fixing blocks are hinged to one end of the electric telescopic rod away from the slider, the first fixing blocks are provided with screws, the screws pass through the first fixing blocks and are rotatably matched with the first fixing blocks, the bottom ends of the screws are fixedly connected to a rotating rod, and the bottom of the rotating rod is hinged to the stepper motor. The motor output shaft is coaxially fixedly connected, and a transmission rod is hinged between adjacent rotating rods; a first airbag is fixedly connected to the arc surface of the arc bottom plate, and the first airbag is connected to a one-way valve; an arc top plate is provided above the arc bottom plate, and a plurality of second fixed blocks are fixedly connected to one side of the arc top plate, and the second fixed blocks are all matched with the screw thread, and a second airbag is fixedly connected to the arc surface of the arc top plate, the first airbag and the second airbag are connected to each other through the one-way valve, and the second airbag is connected to an air pump, and the air pump is electrically connected to a controller, and the controller is used to control the opening and closing of the air pump to control the inflation of the second airbag.

[0013] Beneficial effects: The stepper motor drives the screw and transmission rod system to achieve precise adjustment of the distance between the arc top plate and the arc bottom plate. This design allows medical staff to flexibly adjust the tightness of the fixation device according to the child's limb size and examination needs, ensuring that the child remains still during the examination, thereby improving the accuracy and stability of the examination; the first airbag and the second airbag are respectively arranged on the arc bottom plate and the arc top plate. This airbag fixation method not only reduces the pressure and discomfort on the child's skin, but also improves the comfort and safety of fixation.

[0014] Furthermore, the head fixing assembly includes an arc-shaped head support, which is fixedly connected to the inspection table, and a third airbag is fixedly connected to the arc-shaped surface of the arc-shaped head support, and the third airbag and the air pump are connected to each other.

[0015] Beneficial effect: When a child is examined, the head is placed on the arc-shaped head support, and the third airbag on the arc-shaped head support is inflated by an air pump. At this time, the third airbag can perform a ring-shaped inflation and fixation operation on the child's head, which can effectively fix the child's head and prevent the head from shaking left and right.

[0016] Furthermore, the positioning assembly includes a fixed rod, which is fixedly connected to one side of the examination table. A camera is fixedly connected to the end of the fixed rod away from the examination table. The camera is electrically connected to a controller. The controller is used to receive and analyze the image signal transmitted by the camera to determine whether the fixed position of the child's limbs is appropriate at this time.

[0017] Beneficial effects: By automatically capturing and analyzing images with the camera, medical staff can complete the positioning of children's limbs more quickly without having to make multiple manual adjustments and confirmations. This not only shortens the preparation time before the examination, but also improves the efficiency of the entire examination process; the camera can capture images of children's limbs in real time, and combined with the image processing algorithm or big data analysis technology in the controller, it can accurately analyze and determine the optimal fixed position of children's limbs. This visual-assisted positioning method is more accurate than traditional manual judgment and helps reduce inspection errors caused by inaccurate positioning.

[0018] Furthermore, a plurality of muscle tension sensors are fixedly connected to the outer walls of the first airbag and the second airbag, and the muscle tension sensors are electrically connected to the controller. The controller is used to receive muscle tension signals sent by the muscle tension sensors to identify the muscle tension of the child's limbs at this time.

[0019] Beneficial effects: The muscle tension sensor detects the child's muscle state by monitoring the muscle tension on the surface of the child's limbs. If the muscle tension is high, it means that the muscles on the surface of the child's limbs are relatively tight, which can indicate that the child is under higher pressure from the first airbag and the second airbag. The child is relatively uncomfortable at this time. After the controller receives the muscle tension signal, the controller sends a control signal to control the air pump to stop inflating the first airbag, thereby realizing the function of automatically stopping after reaching the appropriate pressure.

[0020] Furthermore, a plurality of baffles are fixedly connected on the inspection table along the length direction, and a limiting block is symmetrically and fixedly connected to the sliding block, and the limiting block is used to limit the rotation of the sliding block.

[0021] Beneficial effects: When a child is preparing for a radiological examination, medical staff can easily rotate the slider to drive the limb fixation assembly to rotate to the outside of the examination table, thereby providing a barrier-free access channel for the child, allowing the child to lie comfortably on the examination table; at the same time, the coordinated use of the limit block and the baffle effectively limits the rotation range of the slider, avoiding potential damage to the equipment due to excessive rotation.

[0022] Furthermore, an alarm light is fixedly connected to the examination table, and the alarm light is electrically connected to the controller. The controller is used to send an error signal to the alarm light to remind medical staff that the fixing position is wrong.

[0023] Beneficial effect: When the camera detects that the limb fixation component is not fixed in the optimal fixation position of the child's limbs, the controller receives the image signal of the camera, and the controller sends a control signal to control the alarm light to light up to remind medical staff that the optimal fixation position has not been reached at this time, thereby realizing the function of reminding medical staff to assist them in accurately positioning the child's limbs.

[0024] Furthermore, a first air pressure sensor is fixedly connected inside the second airbag, and the first air pressure sensor and a controller are electrically connected. The controller is used to receive an air pressure signal from the first air pressure sensor to identify the air pressure in the second airbag at this time.

[0025] Beneficial effect: The first air pressure sensor can monitor the real-time air pressure in the second airbag at this time. When the controller receives the muscle tension signal, the controller can convert the muscle tension signal into an air pressure value. At this time, the air pump inflates the second airbag. The controller monitors the air pressure value in the second airbag through the first air pressure sensor. When the air pressure value reaches the air pressure value converted by the controller from the muscle tension signal, the controller sends a control signal to control the air pump to stop inflating the second airbag, thereby realizing the function of the controller to accurately adjust the pressure of the second airbag.

[0026] Furthermore, a second air pressure sensor is fixedly connected inside the third airbag, and the second air pressure sensor is electrically connected to the controller. The controller is used to receive the air pressure signal of the second air pressure sensor to identify the air pressure in the third airbag at this time.

[0027] Beneficial effect: The second air pressure sensor can monitor the real-time air pressure value inside the third airbag in real time. The controller sets an air pressure value. When the air pump inflates the inside of the third airbag, when the controller receives the air pressure value signal sent by the second air pressure sensor and reaches the air pressure value set by the controller, the controller sends a control signal to control the air pump to shut down. At this time, the air pump stops inflating the third airbag, thereby realizing the function of the controller to accurately adjust the pressure of the third airbag.

[0028] Furthermore, a telescopic plate is fixedly connected to the arc-shaped top plate, a slot is opened on the arc-shaped bottom plate, an expansion layer is fixedly connected in the slot, the expansion layer is interconnected with the second airbag, the expansion layer is inflated and the surface of the expansion layer is made of a material with a high friction coefficient.

[0029] Beneficial effects: When medical staff position and fix the child's limbs, the expansion layer can use friction to clamp the telescopic plate, so that the child's limbs cannot fall off from between the curved top plate and the curved bottom plate, further increasing the stability of the fixation. At the same time, due to the telescopic nature of the telescopic plate, it can also automatically adjust according to the different thicknesses of the child's limbs, further increasing the adaptability of the device.

DETAILED DESCRIPTION

[0038] The following is further described in detail through specific implementation methods:

[0039] Embodiment 1:

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown: a radiology child examination positioning auxiliary equipment, including an examination table 1 and a controller, a plurality of brackets 2 are fixedly connected to the examination table 1 by bolts, and a slide rail 3 is fixedly connected between two opposite brackets 2 on the length direction side by bolts, and a plurality of sliders 4 are slidably matched on the slide rail 3, and the slider 4 and the slide rail 3 are rotatably matched, and a plurality of electric telescopic rods 5 are fixedly connected to one side of the slider 4 by bolts, and the electric telescopic rods 5 are electrically connected to the controller, and the controller is used to drive the output shaft of the electric telescopic rod 5 to extend and retract; a limb fixing component for fixing the child's limbs is provided at one end of the electric telescopic rod 5 away from the slider 4; a head fixing component for fixing the child's head is provided on the examination table 1; a positioning component for positioning the child's limbs is provided on one side of the examination table 1.

[0041] like Figure 3As shown, the limb fixing assembly includes an arc-shaped base plate 6, the bottom of the arc-shaped base plate 6 is fixedly connected to a motor seat 7 by bolts, a stepper motor 8 is fixedly connected to the motor seat 7 by bolts, the stepper motor 8 is electrically connected to a controller, and the controller is used to drive the stepper motor 8 to rotate forward and reverse.

[0042] A plurality of first fixing blocks 9 are integrally formed on one side wall of the arc-shaped bottom plate 6 close to the stepping motor 8, and the first fixing blocks 9 are hinged to the end of the electric telescopic rod 5 away from the slider 4; a screw 10 is provided on the first fixing block 9, and the screw 10 passes through the first fixing block 9 and rotates with the first fixing block 9, and a rotating rod 11 is integrally formed at the bottom end of the screw 10, and the bottom of the rotating rod 11 is coaxially fixedly connected to the output shaft of the stepping motor 8 by bolts; a transmission rod 12 is hinged between adjacent rotating rods 11.

[0043] A first airbag 13 is fixedly bonded to the arcuate surface of the arcuate bottom plate 6, and the first airbag 13 is connected to a one-way valve; an arcuate top plate 14 is provided above the arcuate bottom plate 6, and a plurality of second fixing blocks 15 are integrally formed on one side of the arcuate top plate 14, and the second fixing blocks 15 are all threadedly matched with the screw rod 10; a second airbag 16 is fixedly bonded to the arcuate surface of the arcuate top plate 14, and the second airbag 16 and the first airbag 13 are connected to each other through a one-way valve, and the second airbag 16 is connected to an air pump, and the air pump and the controller are electrically connected, and the controller is used to control the opening and closing of the air pump to control the inflation of the second airbag 16.

[0044] like Figure 5 As shown, the head fixing assembly includes an arc-shaped head support 17, which is fixedly connected to the inspection table 1 by bolts, and a third airbag 18 is fixedly bonded to the arc-shaped surface of the arc-shaped head support 17, and the third airbag 18 is connected to the air pump.

[0045] like Figure 1 and Figure 2 As shown, the positioning assembly includes a fixing rod 19, which is fixedly connected to one side of the inspection table 1 by bolts, and a camera 20 is fixedly connected to the end of the fixing rod 19 away from the inspection table 1 by bolts. The camera 20 is electrically connected to a controller, and the controller is used to receive and analyze the image signal transmitted by the camera 20 to determine whether the fixed position of the child's limbs is appropriate at this time.

[0046] The specific implementation process is as follows: the medical staff guides the child to lie on the examination table 1, and the medical staff starts the equipment through the controller and prepares to adjust the various components; the child's head is placed on the arc-shaped part of the arc-shaped head support 17, and the third airbag 18 on the arc-shaped surface of the arc-shaped head support 17 is inflated by an air pump. At this time, the third airbag 18 can perform a ring-shaped inflation and fixation operation on the child's head, which can effectively fix the child's head and prevent the head from shaking left and right.

[0047] Then the medical staff slides the slider 4 on the slide rail 3 to a suitable position according to the position of the child's limbs. The electric telescopic rod 5 is used to extend the arc bottom plate 6 to the appropriate position of the child's limbs; the medical staff operates the controller to control the stepper motor 8 to drive the screw 10 to rotate. Since the screw 10 and the first fixing block 9 are rotated and matched, and the screw 10 and the second fixing block 15 are threaded, the rotation of the screw 10 can drive the second fixing block 15 to move up and down, and then drive the arc top plate 14 to move up and down, so as to adjust the distance between the arc top plate 14 and the arc bottom plate 6 to adapt to the child's limb size.

[0048] For example, with the assistance of medical staff, the child's limbs are placed between the arc bottom plate 6 and the arc top plate 14. The medical staff operates the controller to control the stepper motor 8 to rotate clockwise. When the output shaft of the stepper motor 8 rotates clockwise, the adjacent screw rod 10 is driven to rotate clockwise. Since the rotating rod 11 and the screw rod 10 are integrally formed, the rotation of the screw rod 10 can drive the rotating rod 11 to rotate clockwise. Since the rotating rod 11 and the transmission rod 12 are hinged, the clockwise rotation of the rotating rod 11 can drive the transmission rod 12 to move in the clockwise direction. This in turn drives the rotating rod 11 at one end of the transmission rod 12 away from the stepper motor 8 to rotate clockwise, thereby driving the adjacent screw 10 to rotate clockwise, thereby realizing the synchronous clockwise rotation of the screw 10. At this time, the synchronous clockwise rotation of all the screws 10 can drive the adjacent second fixed block 15 to move downward, thereby driving the arc-shaped top plate 14 to move downward to fix the child's limbs; in this embodiment, the stepper motor 8 is a forward and reverse motor, and in this embodiment, the maximum rotation angle of the stepper motor 8 is controlled to be 180°.

[0049] When the curved top plate 14 moves downward, the controller sends a control signal to control the air pump to inflate the second airbag 16. Due to the downward movement of the curved top plate 14, the squeezing pressure of the second airbag 16 on the child's limbs gradually increases. At this time, the internal pressure of the air in the second airbag 16 increases as the squeezing pressure increases. The gas in the second airbag 16 will enter the first airbag 13 through the one-way valve. The first airbag 13 will expand when it receives the air delivered by the second airbag 16. The expansion of the first airbag 13 will lift the child's wrist or ankle. The first airbag 13 and the second airbag 16 will squeeze and cooperate with each other on the child's wrist or ankle to achieve a gentle and effective fixation of the child's limbs.

[0050] By automatically capturing and analyzing images through the camera 20, medical staff can complete the positioning of the child's limbs more quickly without having to make multiple manual adjustments and confirmations. This can not only shorten the preparation time before the examination, but also improve the efficiency of the entire examination process; the camera 20 can capture images of the child's limbs in real time, and combined with the image processing algorithm or big data analysis technology in the controller, it can accurately analyze and determine the optimal fixed position of the child's limbs. This visual-assisted positioning method is more accurate than traditional manual judgment and helps reduce inspection errors caused by inaccurate positioning.

[0051] Embodiment 2:

[0052] like Figure 3 As shown, the difference from Example 1 is that a plurality of muscle tension sensors 21 are fixedly bonded to the outer walls of the first airbag 13 and the second airbag 16, and the muscle tension sensors 21 are electrically connected to the controller. The controller is used to receive the muscle tension signal sent by the muscle tension sensor 21 to identify the size of the muscle tension of the child's limbs at this time.

[0053] The specific implementation process is as follows: the muscle tension sensor 21 detects the child's muscle state by monitoring the muscle tension on the surface of the child's limbs. If the muscle tension is high, it means that the surface muscles of the child's limbs are relatively tight at this time, which can indicate that the child is under high pressure from the first airbag 13 and the second airbag 16. The child is relatively uncomfortable at this time. After the controller receives the muscle tension signal, the controller sends a control signal to control the air pump to stop inflating the second airbag 16, thereby realizing the function of automatically stopping after reaching the appropriate pressure.

[0054] Embodiment 3:

[0055] As attached Figure 2 As shown, the difference from Example 2 is that a plurality of baffles 22 are fixedly connected to the inspection table 1 along the length direction by bolts, and a limit block 23 is symmetrically and integrally formed on the slider 4, and the limit block 23 is used to limit the rotation of the slider 4.

[0056] The specific implementation process is as follows: First, the medical staff guides the child to approach the examination table 1 and prepares to place the child on the examination table. At this time, the baffle 22 on the examination table 1 and the limit block 23 on the slider 4 are both in the initial position; because the slider 4 and the slide rail 3 are designed to rotate together, the medical staff can easily rotate the slider 4 to the outside of the examination table 1, providing an unobstructed passage for the child to enter the examination table, so that the child can lie comfortably on the examination table; in the process of rotating the slider 4, the limit block 23 on the slider 4 will gradually approach and eventually contact the baffle 22 on the examination table 1; the limit block 23 and the baffle 22 jointly limit the further rotation of the slider 4, thereby avoiding potential damage to the equipment caused by excessive rotation.

[0057] Embodiment 4:

[0058] like Figure 1 and Figure 2 As shown, the difference from Example 3 is that an alarm light 24 is fixedly connected to the inspection table 1 by bolts, and the alarm light 24 is electrically connected to the controller, and the controller is used to send an error signal to the alarm light 24 to remind medical staff that the fixing position is wrong.

[0059] The specific implementation process is as follows: when the camera 20 detects that the limb fixation component is not fixed in the optimal fixation position of the child's limbs, the controller receives the image signal of the camera 20, and the controller sends a control signal to control the alarm light 24 to light up to remind medical staff that the optimal fixation position has not been reached at this time, thereby realizing the function of reminding medical staff to assist them in accurately positioning the child's limbs.

[0060] Embodiment 5:

[0061] As attached Figure 3 As shown, the difference from Example 4 is that a first air pressure sensor is fixedly bonded inside the second airbag 16, the first air pressure sensor is electrically connected to the controller, and the controller is used to receive the air pressure signal of the first air pressure sensor to identify the air pressure in the second airbag 16 at this time.

[0062] The specific implementation process is as follows: the first air pressure sensor can monitor the real-time air pressure in the second airbag 16 at this time. When the controller receives the muscle tension signal, the controller can convert the muscle tension signal into an air pressure value. At this time, the air pump inflates the second airbag 16. The controller monitors the air pressure value in the second airbag 16 through the first air pressure sensor. When the air pressure value reaches the air pressure value converted by the controller from the muscle tension signal, the controller sends a control signal to control the air pump to stop inflating the second airbag 16, thereby realizing the function of the controller to accurately adjust the pressure of the second airbag 16.

[0063] Embodiment 6:

[0064] As attached Figure 5 As shown, the difference from Example 5 is that a second air pressure sensor is fixedly bonded inside the third airbag 18, the second air pressure sensor is electrically connected to the controller, and the controller is used to receive the air pressure signal of the second air pressure sensor to identify the air pressure in the third airbag 18 at this time.

[0065] The specific implementation process is as follows: the second air pressure sensor can monitor the real-time air pressure value inside the third airbag 18 in real time. The controller sets an air pressure value. When the air pump inflates the inside of the third airbag 18, when the controller receives the air pressure value signal sent by the second air pressure sensor and reaches the air pressure value set by the controller, the controller sends a control signal to control the air pump to shut down. At this time, the air pump stops inflating the third airbag 18, thereby realizing the controller's function of regulating the pressure of the third airbag 18.

[0066] Embodiment 7:

[0067] As attached Figure 5 and Figure 6 As shown, the difference from Example 6 is that a telescopic plate 25 is fixedly connected to the arc-shaped top plate 14, a slot is opened on the arc-shaped bottom plate 6, an expansion layer 26 is fixedly connected in the slot, the expansion layer 26 is interconnected with the second airbag 16, the expansion layer 26 is inflated and the surface of the expansion layer 26 is made of a material with a high friction coefficient.

[0068] The specific implementation process is as follows: when the medical staff positions and fixes the child's limbs, since the telescopic plate 25 is a telescopic structure, the medical staff can first retract the telescopic plate 25 into the arc-shaped top plate 14 and put the child's limbs between the arc-shaped top plate 14 and the arc-shaped bottom plate 6. At this time, the telescopic plate 25 will extend due to gravity and then be stuck between the expansion layer 26 in the card slot. Since the expansion layer 26 and the second airbag 16 are connected to each other, as the air pump inflates the second airbag 16, the expansion layer 26 will expand, and the expansion layer 26 can then wrap the telescopic plate 25 in the card slot so that the expansion layer 26 can clamp the telescopic plate 25. At the same time, since the surface of the expansion layer 26 is a material with a high friction coefficient, the expansion layer 26 can use friction to clamp the telescopic plate 25, so that the child's limbs cannot fall off from between the arc-shaped top plate 14 and the arc-shaped bottom plate 6, further increasing the stability of the fixation. At the same time, due to the telescopic nature of the telescopic plate 25, it can also be automatically adjusted according to the different thicknesses of the child's limbs, further increasing the adaptability of the device.

[0069] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
