Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a multifunctional auxiliary device for medical imaging diagnosis. Background Art

[0002] Medical imaging diagnosis is the use of medical imaging diagnostic equipment to image the internal structure and organs of the human body in order to understand the anatomical and physiological function status and pathological changes of the human body, and to diagnose and treat human diseases. Common medical imaging equipment includes digital X-ray machines, computer tomography equipment and magnetic resonance imaging systems.

[0003] A digital X-ray machine is mainly composed of an X-ray generator, a flat-panel detector, an image processing system, a control system and a display. When the digital X-ray machine is in use, the control system first determines the amount of X-ray emission, and then the X-ray generator generates X-rays. After the X-rays pass through the patient's body, they are captured by the flat-panel detector. The flat-panel detector converts the captured X-rays into electrical signals, which are then converted into visual images by the image processing system and finally displayed on the display for the doctor to view and make a diagnosis.

[0004] During the use of digital X-ray machines, when obese patients undergo X-ray diagnosis, due to possible uneven fat distribution and reduced muscle mass, the obese patients have a higher density and an absorption angle for X-rays, which results in fewer X-rays passing through the human body and captured by the flat-panel detector, resulting in blurred X-ray imaging, making it inconvenient for medical staff to diagnose the patient's condition. If the amount of X-rays generated is increased, it is easy to cause damage to the patient's body.

[0005] To this end, the prior art has proposed a medical imaging diagnostic device, which adopts a multi-color replacement structure so that shadows and white spots in the image can be clearly presented, thereby improving the diagnostic efficiency of medical staff and allowing patients to intuitively see abnormalities in the image. At the same time, through the setting of a distance adjustment structure and a self-locking structure, the distance between the medical staff and the patient viewing the image can be adjusted. However, the problem of unclear X-ray diagnostic imaging of obese patients has not been solved.

[0006] In view of this, we propose a multifunctional auxiliary device for medical imaging diagnosis. Summary of the invention

[0007] The object of the present invention is to provide a multifunctional auxiliary device for medical imaging diagnosis to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions: A multifunctional auxiliary device for medical imaging diagnosis, comprising a digital X-ray machine, a pressure sensor, a pressure plate, an adjustment component, a flat panel detector, an extrusion component and an extrusion plate; the digital X-ray machine comprises a column, a driving device, a cantilever, an X-ray generator and a detection platform, the column is provided with a driving cavity, the driving cavity is provided with a driving device, the driving device is connected to the cantilever, the cantilever is connected with an X-ray generator, a detection platform is provided under the X-ray generator, the detection platform is slidably connected to the column, and an adjustment cavity is provided on the detection platform; when the digital X-ray machine is in use, the patient lies flat on the detection platform, The medical staff adjusts the position of the column through the control system so that the column and the patient's detection area are located at the same position, and then adjusts the position height of the cantilever through the driving device to change the height of the X-ray generator, and starts the X-ray generator to emit X-rays to examine the patient; the pressure plate is installed on the detection platform, and pressure sensors are provided at both ends of the pressure plate. The pressure sensor adjusts the height of the X-ray generator through the driving device; when the patient lies on the detection platform, the patient exerts pressure on the pressure plate, and the pressure plate transmits the pressure to the pressure sensor, and the pressure sensor transmits the electrical signal to the control system, thereby controlling the descending height of the cantilever; The adjustment component is located below the pressure plate, and the flat-panel detectors are linearly arrayed in the adjustment cavity. When the height of the X-ray generator changes, the driving device drives the flat-panel detector to slide upward through the adjustment component. The flat-panel detector slides vertically upward to reduce the distance between the flat-panel detector and the X-ray generator, thereby improving the imaging effect of the digital X-ray machine and the diagnostic effect of medical staff; the extrusion component is located in the adjustment cavity, and the extrusion plate is located below the flat-panel detector. When the flat-panel detector slides, the adjustment component drives the extrusion plate to move in the center through the extrusion component. The centering movement of the extrusion plate promotes the stability of the adjustment component in lifting the flat-panel detector, thereby maintaining the stability of the flat-panel detector and preventing the flat-panel detector from shaking during the rising process, resulting in uneven capture of X-rays, thereby affecting the clarity of the imaging.

[0010] Preferably, the adjusting assembly comprises an active rod, a driven rod, a return spring, a push plate, an inflatable airbag, an air pipe, a lifting airbag and a lifting plate; the active rod is located in the driving cavity and below the shaft sleeve; an inclined groove is provided on the active rod; the driven rod is arranged vertically with the active rod, and the driven rod is connected to the inner wall of the driving cavity by a return spring; an inclined groove cooperating with the active rod is provided on one end of the driven rod, and the other end of the driven rod is in contact with the push plate; the active rod is below the shaft sleeve, and when the shaft sleeve moves vertically downward, the shaft sleeve will push the active rod to move downward synchronously, and the active rod pushes the driven rod to move synchronously through the inclined groove during the movement, and the driven rod squeezes the return spring to compress the return spring, and when the shaft sleeve is reset vertically upward, the return spring will drive the driven rod to reset, and then drive the active rod to reset position; the push plate is located in the adjusting cavity, and an inflatable airbag is provided in front of the push plate; a lifting airbag is provided in front of the inflatable airbag; the lifting airbag is connected to the inflatable airbag by an air pipe, and a lifting plate is provided above the lifting airbag; a flat-panel detector is fixedly installed on the lifting plate; when the driven rod slides under the action of the active rod, the driven rod pushes the push plate to slide synchronously, and the push plate gradually squeezes the inflatable airbag during the sliding process. The inflatable airbag is subjected to the squeezing force, and the gas inside itself is transferred to the lifting airbag through the air pipe. The gas content in the lifting airbag increases, and the lifting airbag is deformed to push the lifting plate to move vertically upward, and the lifting plate drives the flat-panel detector fixed thereon to move synchronously, thereby changing the height between the flat-panel detector and the X-ray generator, thereby improving the imaging clarity.

[0011] Preferably, the extrusion assembly includes a driving rack, a tension spring, a rotating wheel, a driven rack, an extrusion block, and a support plate; the driving rack is fixedly connected to the push plate and is located below the lifting airbag; the driving rack is connected to the inner wall of the driving cavity by a tension spring; there are two rotating wheels, which are symmetrically arranged on both sides of the driving rack; the rotating wheel is meshed with the driven rack; an extrusion plate is fixedly mounted on the driven rack, and the driving rack is fixedly connected to the push plate. When the push plate slides horizontally under the action of the driven rod, the push plate pushes the driving rack to move synchronously, the driving rack is meshed with the rotating wheel, and then the rotating wheel is driven to rotate, and the rotating wheel drives the driven The rack slides in the center, thereby driving the extrusion plate to slide in the center, and the extrusion plate squeezes the lifting airbag, pushing the gas in the lifting airbag to gather in the middle, thereby enhancing the force of the middle end of the lifting airbag on the lifting plate, thereby promoting the smooth sliding of the lifting plate, thereby ensuring the stability of the flat-panel detector; an extrusion block is fixedly mounted on the driven rack; a support plate is provided above the extrusion block; the support plate is slidably connected to the inner wall of the adjustment cavity, the support plate is located under the lifting plate and contacts the lifting plate, the extrusion block moves synchronously with the driven rack, thereby squeezing and pushing the support plate to slide vertically upward, supporting the lifting plate, and ensuring the smooth movement of the lifting plate.

[0012] Preferably, the push plate is of an I-shaped structure, and the driven rod slides synchronously with the column. When the driven rod drives the push rod to move synchronously, it cannot be guaranteed that the contact point of the driven rod with the push plate is always in the center of the push plate, which causes uneven force on the push plate. The I-shaped structure can improve the uniformity of force, thereby ensuring that the push plate squeezes the inflatable airbag evenly, ensuring that the airflow enters the lifting airbag stably, avoiding insufficient airflow content and resulting in insufficient force of the lifting airbag on the lifting plate, resulting in insufficient rising height of the flat-panel detector.

[0013] Preferably, there is a semicircular protrusion under the push plate, and a groove that cooperates with the push plate is provided on the driving rack.

[0014] Preferably, the inner diameter of the air supply pipe near the inflatable airbag is larger than the inner diameter of the end near the lifting airbag, and the inner diameter of the air supply pipe gradually decreases from the inflatable airbag section to the lifting airbag section, thereby enhancing the squeezing force on the airflow and accelerating the flow speed of the airflow from the inflatable airbag to the lifting airbag, so that the lifting airbag can be quickly inflated to lift the lifting plate.

[0015] Preferably, the linear array at the middle end of the lifting airbag has a lifting spring, which supports the contact between the lifting airbag and the lifting plate, ensuring the force acting on the lifting plate. At the same time, when the digital X-ray machine is reset after work, the lifting spring resets and pulls the top of the lifting airbag downward, thereby enhancing the squeezing force of the lifting airbag on the internal gas, enhancing the speed of the gas flowing into the inflated airbag, and improving the reset efficiency.

[0016] Preferably, the lifting airbag is a bellows-shaped structure, and the extrusion plate is a serrated structure that cooperates with the lifting airbag. The bellows-shaped structure improves the uniformity of the deformation of the lifting airbag, ensures the uniformity of the force on the lifting plate, and improves the smoothness of the movement of the lifting plate. The serrated structure just enters the bellows-shaped structure, thereby enhancing the force of the extrusion plate on the lifting airbag, causing the gas in the lifting airbag to converge toward the middle end, thereby enhancing the pressure at the middle end of the lifting airbag, and further promoting the lifting airbag to pull the tension spring, thereby increasing the force on the lifting plate.

[0017] Preferably, a slot is provided at the bottom end of the lifting plate, and a block cooperating with the lifting plate is provided at the top end of the support plate.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] A technical solution provided by the present invention: like Figures 1 to 8 As shown, a multifunctional auxiliary device for medical imaging diagnosis includes a digital X-ray machine 1, a pressure sensor 2, a pressure plate 3, an adjustment component 4, a flat panel detector 5, an extrusion component 6 and an extrusion plate 7; the digital X-ray machine 1 includes a column 11, a driving device 12, a cantilever 13, an X-ray generator 14 and a detection platform 15, the column 11 is provided with a driving cavity 111, the driving cavity 111 is installed with the driving device 12, the driving device 12 is connected to the cantilever 13, the cantilever 13 is connected with the X-ray generator 14, the A detection platform 15 is provided below the X-ray generator 14, and the detection platform 15 is slidably connected to the column 11, and an adjustment cavity 151 is provided on the detection platform 15; when the digital X-ray machine 1 is in use, the patient lies flat on the detection platform 15, and the medical staff adjusts the position of the column 11 through the control system so that the column 11 and the patient's detection area are located at the same position, and then adjusts the position height of the cantilever 13 through the driving device 12 to change the height of the X-ray generator 14, and starts the X-ray generator 14 to emit X-rays to examine the patient; The motor 121 is fixedly installed at the bottom end of the driving cavity 111, and the motor 121 is fixedly connected to the rotating shaft 122; the rotating shaft 122 is provided with a thread, and a sleeve 123 is slidably installed on the rotating shaft 122; the sleeve 123 is provided with a screw groove that matches the rotating shaft 122, and the cantilever 13 is fixedly installed on the sleeve 123; the pressure sensor 2 transmits an electrical signal to the control system according to the patient's weight, and after the control system determines the height of the X-ray generator 14, it transmits the signal to the motor 121 to control the number of revolutions of the motor 121, and the motor The motor 121 controls the sliding distance of the sleeve 123 on the rotating shaft 122 by the number of rotations, thereby controlling the sliding height of the cantilever 13, thereby controlling the height of the X-ray generator 14. The motor 121 starts to drive the rotating shaft 122 to move synchronously. The rotating shaft 122 cooperates with the screw groove on the sleeve 123 through the thread, thereby driving the sleeve 123 to slide vertically on the rotating shaft 122, thereby driving the cantilever 13 to move synchronously through the sleeve 123, and the cantilever 13 drives the X-ray generator 14 installed thereon to move synchronously, thereby changing the height of the X-ray generator 14. The pressure plate 3 is installed on the detection platform 15, and pressure sensors 2 are provided at both ends of the pressure plate 3. The pressure sensor 2 adjusts the height of the X-ray generator 14 through the driving device 12. When the patient lies on the detection platform 15, the patient exerts pressure on the pressure plate 3, and the pressure plate 3 transmits the pressure to the pressure sensor 2. The pressure sensor 2 transmits the electrical signal to the control system, thereby controlling the descending height of the cantilever 13. According to the different weights of the patients, the pressure sensor 2 is subjected to different pressures, thereby controlling the descending height of the cantilever 13 to be different. At the same time, the pressure sensors 2 are located at both ends of the detection platform 15, thereby avoiding the pressure sensor 2 from absorbing the X-rays emitted by the X-ray generator 14 during the detection process, thereby causing the generation of artifacts, affecting the imaging effect of the digital X-ray machine 1, and affecting the diagnosis effect of medical staff; The adjusting assembly 4 is located below the pressure plate 3, and the flat panel detectors 5 are linearly arrayed in the adjusting cavity 151. The flat panel detectors 5 are multiple linear arrays in the adjusting cavity 151, and cooperate with the X-ray emitter to inspect different parts. In this embodiment, there are three flat panel detectors 5, which correspond to the chest, waist and abdomen, and legs, respectively, to achieve detection and diagnosis of the above parts; when the height of the X-ray generator 14 changes, the driving device 12 drives the flat panel detector 5 to slide upward through the adjusting assembly 4, and the flat panel detector 5 slides vertically upward to reduce the distance between it and the X-ray generator 14, thereby improving the detection and diagnosis of the above parts. The imaging effect of the digital X-ray machine 1 is improved, and the diagnosis effect of the medical staff is improved. The imaging effect of the digital X-ray machine 1 is related to the intensity of the X-ray. The higher the intensity of the X-ray, the higher the imaging density and the clearer the imaging picture. The intensity of the X-ray is inversely proportional to the square of the photographic distance, that is, as the distance between the flat panel detector 5 and the X-ray generator 14 is smaller, the intensity of the X-ray is higher, and the detection image of the patient is clearer, which is convenient for the diagnosis of the medical staff. At the same time, it avoids the problem of increasing the X-ray emission amount during the detection of patients with higher weight, and avoids the damage of more X-rays to patients with higher weight; The squeezing assembly 6 is located in the adjustment cavity 151, and the squeezing plate 7 is located below the flat-panel detector 5. When the flat-panel detector 5 slides, the adjustment assembly 4 drives the squeezing plate 7 to move in the center through the squeezing assembly 6. The centering movement of the squeezing plate 7 promotes the smoothness of the adjustment assembly 4 lifting the flat-panel detector 5, thereby maintaining the stability of the flat-panel detector 5 and preventing the flat-panel detector 5 from shaking during the rising process, thereby affecting the clarity of the imaging. If the flat-panel detector 5 fails to maintain a horizontal state, when the X-rays are captured by the flat-panel detector 5, different capture contents will be caused in different areas, thereby causing artifacts to occur, affecting the diagnosis effect of medical staff. A filter grid is installed in the flat-panel detector 5, and the filter grid is used to filter out the influence of scattered rays on imaging, thereby improving the clarity of the imaging, and facilitating the diagnosis of medical staff.

[0025] The active rod 41 is located in the driving cavity 111 and below the shaft sleeve 123; an inclined groove 411 is provided on the active rod 41; the driven rod 42 is arranged vertically with the active rod 41, and the driven rod 42 is connected to the inner wall of the driving cavity 111 through a return spring 43; an inclined groove 411 cooperating with the active rod 41 is provided on one end of the driven rod 42, and the other end of the driven rod 42 contacts with the push plate 44; the active rod 41 is below the shaft sleeve 123, and when the shaft sleeve 123 moves vertically downward, the shaft sleeve 123 will push the active rod 41 to move downward synchronously, and the active rod 41 squeezes and pushes the driven rod 42 to move synchronously through the inclined groove 411 during the movement, and the driven rod 42 squeezes the return spring 43 to compress the return spring 43, and when the shaft sleeve 123 is reset vertically upward, the return spring 43 will drive the driven rod 42 to reset, and then drive the active rod 41 to reset; The push plate 44 is located in the adjustment cavity 151, and an inflatable airbag 45 is provided in front of the push plate 44; the active rod 41 and the driven rod 42 are located in the driving cavity 111 of the column 11, and will slide synchronously according to the column 11, so as to push the push plates 44 under different flat-panel detectors 5. The push plate 44 is an I-shaped structure 441, and the driven rod 42 slides synchronously with the column 11. When the driven rod 42 drives the push rod to move synchronously, it cannot be guaranteed that the contact point of the driven rod 42 with the push plate 44 is always in the center of the push plate 44, so that the push plate 44 is unevenly stressed. The I-shaped structure 441 can improve the uniformity of stress, so as to ensure that the push plate 44 squeezes the inflatable airbag 45 uniformly, and ensures that the airflow enters the lifting airbag 47 stably, so as to avoid insufficient airflow content and thus insufficient force of the lifting airbag 47 on the lifting plate 48, resulting in insufficient lifting height of the flat-panel detector 5; the inflatable airbag 45 is in front of the A lifting airbag 47 is provided on the side; the lifting airbag 47 is connected to the inflatable airbag 45 through an air pipe 46, and a lifting plate 48 is provided above the lifting airbag 47; a flat-panel detector 5 is fixedly mounted on the lifting plate 48; when the driven rod 42 slides under the action of the active rod 41, the driven rod 42 pushes the push plate 44 to slide synchronously, and the push plate 44 gradually squeezes the inflatable airbag 45 during the sliding process. The inflatable airbag 45 is subjected to the squeezing force, and the gas inside itself is transferred to the lifting airbag 47 through the air pipe 46, and the gas content in the lifting airbag 47 increases. Since the lifting airbag 47 is squeezed all around, the inflatable airbag 45 can only be deformed in the vertical direction. The deformation of the lifting airbag 47 pushes the lifting plate 48 to move vertically upward, and the lifting plate 48 drives the flat-panel detector 5 fixed thereon to move synchronously, thereby changing the height between the flat-panel detector 5 and the X-ray generator 14, thereby improving the imaging clarity; The inner diameter of the end of the air supply pipe 46 close to the inflatable airbag 45 is larger than the inner diameter of the end close to the lifting airbag 47. The inner diameter of the air supply pipe 46 gradually decreases from the inflatable airbag 45 section to the lifting airbag 47 section, thereby enhancing the squeezing force on the airflow and accelerating the flow speed of the airflow from the inflatable airbag 45 to the lifting airbag 47, so that the lifting airbag 47 can be quickly inflated to lift the lifting plate 48; the lifting airbag 47 has a lifting spring 471 in the linear array at the middle end, and the lifting spring 471 supports the contact between the lifting airbag 47 and the lifting plate 48, ensuring the force on the lifting plate 48. At the same time, when the digital X-ray machine 1 is reset after work, the lifting spring 471 resets and pulls the top of the lifting airbag 47 downward, thereby enhancing the squeezing force of the lifting airbag 47 on the internal gas, enhancing the speed of the gas flowing into the inflatable airbag 45, and improving the efficiency of the reset; The sleeve 123 slides vertically under the action of the motor 121. During the downward movement of the sleeve 123, it squeezes and pushes the active rod 41 to move vertically downward. The active rod 41 pushes the driven rod 42 to slide horizontally through the inclined groove 411. The driven rod 42 pushes the push plate 44 to slide horizontally. The push plate 44 squeezes the inflatable airbag 45. The inflatable airbag 45 is squeezed and the gas inside it is transmitted to the lifting airbag 47 through the air pipe 46. The gas inside the lifting airbag 47 increases and deforms, pushing the lifting plate 48 to move vertically upward. The lifting plate 48 drives the flat-panel detector 5 to move vertically upward.

[0026] The driving rack 61 is fixedly connected to the push plate 44 and is located below the lifting airbag 47; the driving rack 61 is connected to the inner wall of the driving chamber 111 through a tension spring 62; the lifting airbag 47 is a bellows-shaped structure 472, and the extrusion plate 7 is a serrated structure 71 that matches the lifting airbag 47. The bellows-shaped structure 472 improves the uniformity of the deformation of the lifting airbag 47, ensures the uniformity of the force on the lifting plate 48, and improves the stability of the movement of the lifting plate 48. The serrated structure 71 just enters the bellows-shaped structure 472, thereby enhancing the force of the extrusion plate 7 on the lifting airbag 47, so that the gas in the lifting airbag 47 converges to the middle end, thereby enhancing the pressure at the middle end of the lifting airbag 47, and then promoting the lifting airbag 47 to pull the tension spring 62, thereby enhancing the force on the lifting plate 48; There are two rotating wheels 63, which are symmetrically arranged on both sides of the driving rack 61; the rotating wheel 63 is meshed with the driven rack 64, and the driven rack 64 and the driving rack 61 are staggered up and down, and the movements of the two will not interfere with each other; the driven rack 64 is fixedly installed with an extrusion plate 7, and the driving rack 61 is fixedly connected to the push plate 44. When the push plate 44 slides horizontally under the action of the driven rod 42, the push plate 44 pushes the driving rack 61 to move synchronously, and the driving rack 61 is meshed with the rotating wheel 63, thereby driving the rotating wheel 63 to rotate, and the rotating wheel 63 drives the driven rack 64 to slide in the center, and then drives the extrusion plate 7 to slide in the center, and the extrusion plate 7 is pressed. The plate 7 squeezes the lifting airbag 47, pushing the gas in the lifting airbag 47 to converge toward the middle, thereby increasing the force of the middle end of the lifting airbag 47 on the lifting plate 48, thereby promoting the smooth sliding of the lifting plate 48, thereby ensuring the stability of the flat panel detector 5; the lower part of the push plate 44 is a semicircular protrusion 442, and the driving rack 61 is provided with a groove 611 that cooperates with the push plate 44. The semicircular protrusion 442 of the push plate 44 cooperates with the groove 611 of the driving rack 61, thereby increasing the contact area between the push plate 44 and the driving rack 61, thereby increasing the uniformity of the force on the driving rack 61, thereby ensuring the smooth movement of the driving rack 61; The driven rack 64 is fixedly mounted with an extrusion block 65; a support plate 66 is arranged above the extrusion block 65; the support plate 66 is slidably connected to the inner wall of the adjustment chamber 151, and the support plate 66 is located below the lifting plate 48 and contacts the lifting plate 48. The extrusion block 65 moves synchronously with the driven rack 64, and then squeezes and pushes the support plate 66 to slide vertically upward, supporting the lifting plate 48 to ensure the stability of the movement of the lifting plate 48. The support plate 66 cooperates with the lifting airbag 47 to improve the lifting of the lifting plate. The lifting plate 48 is stable in motion. The support plate 66 is symmetrically distributed with the lifting airbag 47 as the center, which improves the uniformity of the force on the lifting plate 48, thereby ensuring the stable rise of the lifting plate 48. The bottom end of the lifting plate 48 is provided with a slot 481, and the top end of the support plate 66 is provided with a block 661 that cooperates with the lifting plate 48. The cooperation between the slot 481 and the block 661 increases the force between the lifting plate 48 and the support plate 66, thereby improving the stability of the connection and ensuring the stability of the support plate 66 supporting the lifting plate 48. The push plate 44 slides horizontally under the action of the driven plate, and the push plate 44 pushes the driving rack 61 to move synchronously. The driving rack 61 meshes with the rotating wheel 63 to drive the rotating wheel 63 to rotate. The rotation of the rotating wheel 63 drives the driven rack 64 to slide in the center. The driven rack 64 drives the extrusion plate 7 fixedly connected to it to move in the center, squeezes the lifting airbag 47, ensures the extrusion force on the lifting airbag 47, increases the displacement of the lifting airbag 47 in the vertical direction, and ensures the vertical upward sliding of the lifting plate 48. At the same time, the driven rack 64 drives the extrusion block 65 to move synchronously, and the extrusion block 65 pushes the support plate 66 to slide vertically upward. The support plate 66 keeps synchronous movement with the lifting airbag 47 to provide support force for the lifting plate 48, ensure the stability of the lifting plate 48, and then ensure the stability of the flat-panel detector 5, and prevent the flat-panel detector 5 from shaking.
