Description

Technical Field

[0001] The invention relates to the technical field of medical imaging, in particular to a suspended multifunctional dynamic digital X-ray imaging system. Background Art

[0002] Traditional X-ray imaging equipment, such as single DR equipment or digital gastrointestinal machines, although each plays an important role in specific fields, also has some limitations, which to some extent affect the efficiency and accuracy of medical diagnosis.

[0003] Traditional DR equipment is mainly used for routine X-ray examinations of the chest, abdomen, spine, limbs and other parts. The suspended dynamic DR can move freely on the ceiling track due to its cantilever design, allowing doctors to quickly adjust the imaging angle. Patients can easily complete the examination whether they are standing, lying or sitting, which is especially important for patients with limited mobility or who need a specific posture. The dynamic perspective function of the digital gastrointestinal machine enables doctors to continuously observe the flow of contrast agents and judge functional disorders of the gastrointestinal tract, such as esophageal motility abnormalities or poor gastric emptying. Its professional bed design structure that can rotate at positive and negative angles simplifies the operation process, improves the inspection efficiency, and reduces the possibility of misdiagnosis. However, this design currently requires hospitals to be equipped with a variety of different types of X-ray imaging equipment to meet the inspection needs of different parts. For example, when conducting a digestive tract examination, doctors must use a special digital gastrointestinal machine instead of a DR device; similarly, when conducting a limb fracture examination, doctors prefer to use a DR device. The single function of this equipment has led to a reduction in equipment utilization, increasing the procurement cost and management difficulty of the hospital. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a suspended multifunctional dynamic digital X-ray imaging system, which can reduce the procurement cost of the hospital and improve the utilization efficiency of medical resources.

[0005] In order to solve the above technical problems, the technical solution of the present invention is as follows:

[0006] A suspended multifunctional dynamic digital X-ray imaging system, comprising:

[0007] The X-ray suspension device comprises a telescopic rod and an X-ray generating device, wherein the top end of the telescopic rod is fixedly mounted on a fixing seat and performs telescopic movement in a vertical direction, and an L-shaped bracket is provided at the end of the telescopic rod, and a rotating bearing is provided on the L-shaped bracket; the X-ray generating device is slidably connected to the telescopic rod through the rotating bearing;

[0008] An X-ray bed moving device comprises a bed and a flat-panel detector, wherein the bed is used to carry patients and can adjust height and angle as required; the flat-panel detector is horizontally arranged below the bed and moves horizontally below the bed to capture X-ray images at different positions, thereby realizing multifunctional dynamic digital imaging;

[0009] A column, which is fixed vertically to the ground and provided with a base for fixing;

[0010] A lifting mechanism is arranged on the upright column and drives the photographic bed to lift and lower over a large range;

[0011] A rotating mechanism is arranged on the column and drives the photographic bed to rotate at a wide range of positive and negative angles;

[0012] X-ray is an X-ray source used to generate X-rays for imaging.

[0013] Furthermore, the X-ray suspension device also includes:

[0014] The guide rail is installed horizontally and fixed on the beam on the wall;

[0015] The longitudinal movable guide rail is slidably mounted on the transverse mounting guide rail and slides left and right along the transverse mounting guide rail.

[0016] Furthermore, a cable reel is provided on the longitudinal movable guide rail for automatically reeling in the cable.

[0017] Furthermore, the radiographic bed is provided with a foot pedal, a detachable handle and a detachable shoulder support for the patient to step on and grasp.

[0018] Furthermore, the lifting mechanism comprises:

[0019] A sprocket or pulley is arranged on the column;

[0020] The motor drives the chain to rotate, and the chain drives the sprocket or pulley to rotate, so as to push the photography bed up or down through mechanical transmission.

[0021] Furthermore, the rotating mechanism comprises:

[0022] A gear, disposed between the column and the photography bed;

[0023] The motor drives the gear to rotate, and the double gears are engaged to transmit motion, so as to drive the photography bed to rotate.

[0024] The above solution of the present invention includes at least the following beneficial effects:

[0025] The X-ray suspension device in the system achieves flexible adjustment of the height and angle of the X-ray source through the telescopic movement of the telescopic rod in the vertical direction, and the sliding connection of the X-ray generator on the telescopic rod through the rotating bearing. This enables the system to adapt to patients of different body shapes and conditions, providing doctors with more diverse examination angles and position options.

[0026] The radiographic bed can be adjusted in height and angle as needed, and the flat-panel detector can be moved horizontally under the radiographic bed, further enhancing the flexibility and adaptability of the system. Doctors can easily adjust the equipment configuration according to examination needs, capture X-ray images at different positions, and achieve multifunctional dynamic digital imaging.

[0027] The setting of lifting and rotating mechanisms enables the radiographic bed to be quickly and accurately adjusted to the required height and angle, shortening the examination time and improving work efficiency. The horizontal movement and dynamic imaging capabilities of the flat-panel detector enable the system to capture and record the patient's X-ray images in real time, providing doctors with clearer and more accurate diagnostic evidence. This helps doctors to more accurately judge the patient's condition and develop a more appropriate treatment plan.

[0028] The system integrates the functions of DR (digital X-ray imaging) and digital gastrointestinal machine, realizing multiple uses of one machine and reducing the cost of purchasing multiple devices for hospitals. The hanging design makes the system more space-saving, reduces the floor space of the hospital's radiology department, and provides more available space for the hospital.

[0034] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides a suspended multifunctional dynamic digital X-ray imaging system, comprising:

[0036] The X-ray suspension device comprises a telescopic rod 3 and an X-ray generating device 4, wherein the top end of the telescopic rod 3 is fixedly mounted on a fixed seat and performs telescopic movement in the vertical direction, and an L-shaped bracket is provided at the end of the telescopic rod 3, and a rotating bearing 16 is provided on the L-shaped bracket; the X-ray generating device 4 is slidably connected to the telescopic rod 3 through the rotating bearing 16;

[0037] The X-ray bed moving device comprises a bed 15 and a flat panel detector 13, wherein the bed 15 is used to carry the patient and adjust the height and angle as required; the flat panel detector 13 is horizontally arranged below the bed 15 and moves horizontally below the bed 15 to capture X-ray images at different positions, thereby realizing multifunctional dynamic digital imaging;

[0038] A column 5, which is vertically fixed to the ground and provided with a base 7 for fixing;

[0039] A lifting mechanism is disposed on the column 5 and drives the photographic bed 15 to rise and fall;

[0040] The rotating mechanism is arranged on the column 5 and drives the photographic bed 15 to rotate.

[0041] The X-ray 6 is an X-ray generating source, which is used to generate X-rays for imaging.

[0042] In the embodiment of the present invention, the top end of the telescopic rod 3 is fixedly mounted in a fixed seat on the wall and can perform telescopic movement in the vertical direction. This design allows the X-ray generator 4 to flexibly adjust its position in the vertical direction to adapt to the height and examination requirements of different patients. An L-shaped bracket is provided at the end of the telescopic rod 3, and a rotating bearing 16 is installed on the L-shaped bracket. The rotating bearing 16 provides a smooth rotating interface, so that the X-ray generator 4 can slide on the telescopic rod 3 and rotate around the rotating bearing 16 at a certain angle, thereby further increasing the flexibility of X-ray projection.

[0043] The X-ray generator 4 is slidably connected to the telescopic rod 3 through a rotating bearing 16. When the projection angle or position of the X-ray needs to be adjusted, the operator can easily slide or rotate the X-ray generator 4. The radiographic bed 15 is used to carry the patient and adjust the height and angle according to the examination requirements. The design of the radiographic bed 15 takes into account the patient's comfort and examination efficiency. The flat-panel detector 13 is horizontally arranged below the radiographic bed 15 to capture X-ray images. In order to capture X-ray images at different positions, the flat-panel detector 13 can move horizontally below the radiographic bed 15. This function is achieved by an electric push rod (or other mechanisms such as gear racks, screw slides, linear guides, etc.), so that the flat-panel detector 13 can accurately adjust its position as needed.

[0044] The column 5 is fixed vertically to the ground and is provided with a base 7 for fixing. The column 5 provides a stable support structure to ensure the stability of the entire X-ray bed moving device. The lifting mechanism is arranged on the column 5, including a chain, a motor, a sprocket or a pulley. A chain is arranged on the lifting column, and a motor is arranged at the bottom of the lifting column. When the motor is started, it drives the chain to rotate, and the chain in turn drives the sprocket or pulley to rotate, thereby pushing the photography bed 15 up or down. This design allows the height of the photography bed 15 to be adjusted according to the patient's height and examination requirements. The rotating mechanism is also arranged on the column 5, including gears and a motor. A double gear is arranged between the lifting column and the X-ray bed 15, and the double gears are meshed. When the motor is started, it drives the gear to transmit motion through the meshing between the gears, driving the photography bed 15 to rotate. In addition, the rotating mechanism can also be realized by a worm gear. When the worm rotates, its spiral shape causes the worm to mesh with the tooth surface of the worm wheel, thereby driving the photography bed 15 to rotate. This design allows the angle of the photography bed 15 to be adjusted according to the examination requirements. The X-ray 6 is an X-ray generating source, which is used to generate X-rays for imaging. After the X-rays pass through the patient's body, they are captured by the flat panel detector 13 and converted into digital images, thereby realizing multifunctional dynamic digital imaging.

[0045] By adjusting the positional relationship between the X-ray bed 15, the flat panel detector 13 and the X-ray generator 4, the suspended DR system can have the function of a digital gastrointestinal machine. For example, when it is necessary to take gastrointestinal images, the angle of the bed 15 and the position of the flat panel detector 13 can be adjusted to obtain the best imaging effect. The system can adapt to the body position examination needs of different patients and disease conditions. Whether standing, lying or lying on the side, the examination needs can be met by adjusting the various components of the system.

[0046] Through the design of telescopic rod 3, rotary bearing 16, lifting and rotating mechanism, the height, angle and position of X-ray generator 4 and radiographic bed 15 can be flexibly adjusted to meet the examination needs of different patients. The flat-panel detector 13 can move horizontally under the radiographic bed 15 to capture X-ray images at different positions, improving the clarity and accuracy of imaging. The use of electric push rods, chains, motors and other mechanisms makes the operation of the system more convenient and efficient, reducing the burden on medical staff. It has the function of a digital gastrointestinal machine, which can adapt to the body position examination needs of different patients and symptoms, and expands the application range of the system. The design of the radiographic bed 15 takes into account the comfort of the patient, and is equipped with a foot pedal 11, a detachable handle 12 and a detachable shoulder rest 17. The patient can step on the foot pedal stably, grab the handle and keep the body balanced.

[0047] like Figures 1 to 3 As shown, the X-ray suspension device also includes:

[0048] The guide rail 1 is installed horizontally and fixedly mounted on the beam on the wall;

[0049] The longitudinal movable guide rail 2 is slidably mounted on the transverse mounting guide rail 1 and slides left and right along the transverse mounting guide rail 1 .

[0050] In the embodiment of the present invention, the transverse mounting rail 1 is fixedly mounted on the beam on the wall, providing a stable transverse support foundation for the entire X-ray suspension device. The beam serves as a load-bearing structure to ensure that the transverse mounting rail 1 can be firmly fixed thereon to bear the weight of subsequent components and the force during movement.

[0051] The longitudinal movable guide rail 2 is slidably mounted on the transverse mounting guide rail 1, and the two are connected by a sliding mechanism (such as a pulley, a slide groove, etc.). The longitudinal movable guide rail 2 can slide left and right along the transverse mounting guide rail 1. This design allows the X-ray suspension device to flexibly adjust its position in the horizontal direction. The design of the sliding mechanism ensures the stability and accuracy of the longitudinal movable guide rail 2 during the sliding process, ensuring that the X-ray generating device can accurately reach the predetermined position.

[0052] The top of the telescopic rod 3 is fixedly mounted on the longitudinal movable guide rail 2, and performs telescopic movement in the vertical direction. The X-ray generating device 4 is slidably connected to the telescopic rod 3 through a rotating bearing 16, and can move in the vertical direction with the telescopic rod 3, and rotate around the rotating bearing 16 at a certain angle. When the longitudinal movable guide rail 2 slides along the transverse mounting guide rail 1, the telescopic rod 3 and the X-ray generating device 4 also move accordingly, realizing the flexible positioning of the X-ray suspension device in three-dimensional space. A wire take-up device is provided on the longitudinal movable guide rail 2 for automatically winding up the cable. When the longitudinal movable guide rail 2 slides, the wire take-up device 14 can automatically adjust the length of the cable to avoid the cable from being entangled or dragging on the ground, thereby ensuring a clean and safe working environment.

[0053] The X-ray suspension device realizes flexible movement in the horizontal direction through the design of the horizontal mounting rail 1 and the longitudinal movable rail 2, which greatly increases the flexibility and adaptability of X-ray shooting. The telescopic function of the telescopic rod 3 and the rotation function of the X-ray generator 4 further expand the movement range of the device, so that the X-ray can be accurately projected to any part of the patient's body. The sliding design of the longitudinal movable rail 2 allows the operator to easily adjust the position of the X-ray suspension device without the effort of moving or adjusting heavy equipment. The design of the cable collector reduces the difficulty of cable management and improves work efficiency and safety.

[0054] The flexible positioning function of the X-ray suspension device allows the operator to accurately adjust the projection angle and position of the X-ray according to the patient's body shape and examination needs, thereby optimizing the imaging quality. It avoids the problem of blurred or deformed imaging caused by the fixed position of the equipment, and improves the accuracy and reliability of diagnosis. The flexibility and adaptability of the X-ray suspension device enable it to be used in a variety of medical examination scenarios, such as orthopedics, internal medicine, surgery, etc. It meets the examination needs of different patients and different symptoms, and expands the application scope and market potential of medical equipment.

[0055] like Figures 1 to 3 As shown, a cable take-up device 14 is provided on the longitudinal movable guide rail for automatically reeling in the cable.

[0056] In an embodiment of the present invention, the longitudinal movable guide rail 2 is slidably mounted on the transverse mounting guide rail 1, and can slide left and right along the transverse mounting guide rail 1. This design allows the entire X-ray suspension device to flexibly adjust its position in the horizontal direction to adapt to different shooting requirements. The wire take-up device 14 is fixedly mounted on the longitudinal movable guide rail 2 and is connected to the cable on the guide rail. A spring mechanism or a motor drive mechanism is provided inside the wire take-up device 14 for automatically winding up the cable. When the longitudinal movable guide rail 2 slides, the cable will move accordingly, and the wire take-up device 14 can sense the change in cable tension and automatically adjust the winding speed to ensure that the cable remains taut and does not drag on the ground or get tangled.

[0057] When the operator needs to move the longitudinal movable guide rail 2, the longitudinal movable guide rail 2 starts to slide according to the command, and at the same time drives the take-up device 14 and the cable connected thereto to move together. The take-up device 14 senses the change in cable tension and automatically adjusts the winding speed to ensure that the cable is always kept taut. When the longitudinal movable guide rail 2 stops sliding, the locking mechanism of the take-up device 14 locks the cable to prevent it from loosening or slipping out.

[0058] The automatic winding function of the cable reel 14 greatly reduces the operator's time for manually managing cables, thereby improving work efficiency. Operators can focus more on the X-ray shooting itself without being distracted by managing cables. The cable reel 14 ensures that the cables are always kept taut, avoiding safety hazards such as cables dragging on the ground or getting entangled. In a medical environment, cable management is crucial to the safety of patients and the operation of medical staff. The design of the cable reel 14 effectively improves the safety of the working environment. The automatic winding function of the cable reel 14 reduces the wear and tear of the cables, thereby extending the service life of the cables, which means reducing the frequency and cost of replacing cables for medical institutions. The cable reel 14 neatly winds up the cables, making the entire X-ray suspension device look neater and more orderly.

[0059] like Figures 1 to 3 As shown, the radiographic bed 15 is provided with a foot pedal 11, a detachable handle 12 and a detachable shoulder support 17 for the patient to step on and hold stably.

[0060] In the embodiment of the present invention, the foot pedal 11 is installed at the bottom of the radiographic bed 15, which is convenient for patients to step on. When patients need to undergo X-ray examination, they can step their feet stably on the foot pedal 11. The foot pedal 11 provides an additional support point to help patients maintain body balance, especially when the radiographic bed 15 is raised, lowered, tilted, etc. The foot pedal 11 not only helps the stability of the patient during the radiographic process, but also can serve as a temporary support point for the patient in an emergency to increase safety.

[0061] The handle 12 is installed on the edge of the radiographic bed 15, which is convenient for the patient to hold. During the radiographic process, especially when the radiographic bed 15 is moved, tilted, etc., the patient can hold the handle 12 with both hands. The handle 12 provides an additional support point for the patient, helping them to maintain body balance and reduce the discomfort caused by body movement. The shoulder rest 17 is installed at one end of the radiographic bed, and when the bed rotates, it fixes the patient's two shoulders to prevent the patient from sliding under the bed.

[0062] The design of the footrest 11, handle 12 and shoulder rest 17 fully considers the comfort and stability of the patient, helps the patient relax and cooperate during the photography process, and reduces the discomfort caused by body movement, which helps to improve the patient's examination experience and satisfaction and promote the harmony of the doctor-patient relationship. The footrest 11, handle 12 and shoulder rest 17 provide the patient with additional support points, which helps the patient to balance his body during the photography process. In particular, when the photography bed 15 is raised, lowered, tilted, etc., these auxiliary facilities can effectively prevent the patient from falling or getting injured due to loss of balance, which helps to improve the safety of the examination and reduce the occurrence of accidents.

[0063] The handle 12, shoulder support 17 and cup holder 18 are all removable and installable, and the compressor 19 can be laid flat or upright. When the device is used for digital gastrointestinal examination of patients, the handle 12, shoulder support 17 and cup holder 18 can be quickly installed to protect the patient when the imaging bed rotates and facilitate the patient to take and place the cup containing barium meal during the examination. The compressor 19 is perpendicular to the imaging bed and can slide along the track 20. The patient's stomach can be compressed by the extended compression cup to reduce the dose required for X-rays to penetrate the tissue, making the image clearer. When the device is used for ordinary DR photography, the handle 12, shoulder support 17 and cup holder 18 can be quickly removed to meet the needs of shooting in various body positions, and the compressor 19 can be laid flat on the imaging bed.

[0064] like Figures 1 to 3 As shown, the lifting mechanism comprises:

[0065] A sprocket or pulley 9 is arranged on the column 5;

[0066] The motor 8 drives the chain to rotate, and the chain drives the sprocket or pulley 9 to rotate, so as to push the photography bed 15 up or down through mechanical transmission.

[0067] In the embodiment of the present invention, the column 5 serves as the main supporting structure of the lifting mechanism, and is fixedly installed below or on both sides of the photographic bed 15 to provide guidance and stability for the lifting movement. The sprocket or pulley 9 is installed on the column 5, meshing or contacting with the chain. When the chain rotates, the sprocket or pulley 9 will rotate accordingly. The motor 8 serves as a power source to drive the chain to rotate. The output shaft of the motor 8 is connected to one or more sprockets of the chain to output power through rotation. The chain serves as a transmission element to connect the motor 8 and the sprocket or pulley 9. The chain transmits and converts power through the sprocket, and converts the rotational motion of the motor 8 into linear motion. The photographic bed 15 is connected to the lifting mechanism, and the lifting or lowering is achieved through the movement of the lifting mechanism.

[0068] When the motor 8 is started, its output shaft starts to rotate, driving the sprocket connected to it to rotate. The sprocket transmits the rotational motion to the sprocket or pulley 9 through the chain. The sprocket or pulley 9 starts to rotate under the drive of the chain. Since the sprocket or pulley 9 is connected to the lifting mechanism of the photography bed 15, its rotation will be converted into a linear motion of the photography bed 15 to achieve lifting or lowering. The column 5 provides guidance and stability for the lifting motion. During the lifting process, the photography bed 15 moves smoothly along the track of the column 5 to ensure the accuracy and safety of the lifting.

[0069] The chain is driven by the motor 8 to rotate, which in turn drives the sprocket or pulley 9 to rotate, thereby realizing the rapid lifting and lowering of the photographic bed 15. This mechanical transmission method has the advantages of simple structure, high transmission efficiency, good reliability, etc., and can improve the lifting efficiency. The column 5 provides a stable support structure for the lifting mechanism to ensure that the photographic bed 15 always remains stable during the lifting process. In addition, through reasonable transmission design and control strategy, the stability and safety of the lifting mechanism can be further improved to prevent accidents. The lifting mechanism adopts a modular design, and the components are tightly connected and the structure is clear. This design facilitates the maintenance and maintenance of the equipment, reducing the maintenance cost and difficulty of use. The efficient and smooth operation of the lifting mechanism makes the lifting process of the photographic bed 15 more comfortable and convenient. For medical equipment that requires frequent lifting operations, this design can improve user experience and satisfaction.

[0070] like Figures 1 to 3 As shown, the rotating mechanism comprises:

[0071] The gear 10 is disposed between the column 5 and the photographic bed 15;

[0072] The motor 8 drives the gear 10 to rotate, and the two gears are engaged to transmit motion, so as to drive the photography bed 15 to rotate.

[0073] In the embodiment of the present invention, the column 5 is connected to the photographic bed 15 as the main supporting structure of the rotating mechanism, providing a stable foundation for the rotating motion. The gear 10 is arranged between the column 5 and the photographic bed 15, and meshes with the driving component of the photographic bed 15 (such as the gear on the rotating shaft). When the gear 10 rotates, the rotating motion is transmitted to the photographic bed 15 through the gear meshing. The motor 8 is connected to the gear 10 as the power source of the rotating mechanism to drive it to rotate. The output shaft of the motor 8 is connected to the shaft of the gear 10 through a coupling or directly to ensure efficient transmission of power.

[0074] When the motor 8 is started, its output shaft starts to rotate, driving the gear 10 connected thereto to rotate. The gear 10 meshes with the gear (or similar component) on the photographic bed 15. Due to the meshing of the gears, when the gear 10 rotates, it will drive the gear on the photographic bed 15 to rotate, thereby realizing the rotational movement of the photographic bed 15. Under the action of the gear meshing, the photographic bed 15 rotates around the axis of the column 5. The speed and direction of rotation are determined by the speed and direction of the motor 8, and can be precisely adjusted by the control system. By driving the gear 10 to rotate by the motor 8, and then using the double gear meshing to transmit the motion, the precise rotation of the photographic bed 15 can be achieved. This mechanical transmission method has the advantages of high transmission efficiency and good reliability, and can ensure the stability and accuracy of the photographic bed during rotation.

[0075] The rotating movement of the photographic bed 15 allows the patient to adjust the shooting angle by rotating without moving the body. This helps to improve the inspection efficiency and reduce the time cost of patients and medical staff. In inspections of the gastrointestinal tract, urinary system, etc., patients need to maintain a specific tilted posture for a long time. The rotating function of the photographic bed 15 allows the patient to adjust the shooting angle by rotating without moving the body, thereby reducing the patient's discomfort. By adjusting the speed and direction of the motor 8, the rotation speed and angle of the photographic bed 15 can be controlled. This flexibility enables the rotating mechanism to adapt to a variety of inspection needs and improves the versatility and practicality of medical equipment. The rotating mechanism adopts a mechanical transmission method, and the structure is relatively simple and reliable. This design facilitates the maintenance and maintenance of the equipment, reduces the maintenance cost and difficulty of use. At the same time, due to the fewer mechanical transmission components, the failure rate is relatively low.

[0076] Optionally, in Figure 4 A telescopic rod 3 and a flat-panel detector 13 can be added to facilitate the patient to take a chest X-ray. The chest can be attached to the housing of the flat-panel detector, and the patient's chest is closest to the flat-panel detector, ensuring the clarity and accuracy of the imaging.

[0077] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
