Description

Technical Field

[0001] This invention relates to the field of X-ray machine technology, and in particular to a flat panel detector for a portable X-ray machine. Background Technology

[0002] A mobile digital X-ray machine is a medical device that emits X-rays and can perform radiological examinations and radiotherapy on human tissues. Because it is mobile, it is very convenient to use; medical staff can move the X-ray machine to wards as needed to diagnose or treat patients who are difficult to move.

[0003] During diagnosis or treatment, the imaging site is usually placed between a flat panel detector and an X-ray source. Chest X-ray examinations typically refer to anteroposterior and lateral views of the chest. This examination helps doctors observe lesions in the lungs, pleural cavity, mediastinum, and heart. Some patients with chest lesions have difficulty standing, making chest X-ray examinations inconvenient when standing. When taking X-rays on a bed, if the patient is unstable, it can affect the examination results and is not safe. Therefore, a flat panel detector for portable X-ray machines is needed. Summary of the Invention

[0004] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes a flat panel detector for a portable X-ray imaging machine.

[0005] A flat panel detector for a portable X-ray imaging machine, mounted on one side of a bed board, includes:

[0006] Portable seat;

[0007] A lifting mechanism is installed on the movable base;

[0008] A first mounting bracket is mounted on the lifting mechanism; a motor drive mechanism and a second mounting bracket are mounted on the first mounting bracket, and the second mounting bracket is connected to the output shaft of the motor drive mechanism, so that the second mounting bracket can be driven to rotate vertically through the motor drive mechanism.

[0009] The transmitter is mounted on the second mounting bracket;

[0010] The detector plate is mounted on the second mounting bracket and is arranged parallel to the transmitter;

[0011] Protective components are installed on both sides of the detection plate;

[0012] A trigger component is installed on the detection plate. When the detection plate is parallel to the bed board, the trigger component is raised and lowered by the lifting mechanism to abut against the bed board, thereby generating compressed air to make the protective component perpendicular to the detection plate.

[0013] In one possible technical solution, the triggering component further includes:

[0014] A support plate is mounted on the detector plate;

[0015] The first trigger block is elastically connected to the support plate;

[0016] The second trigger block is installed on the first trigger block;

[0017] A piston assembly is mounted on the detection plate and located below the second trigger block. The piston assembly has a first sleeve and a first piston. The first piston is located inside the first sleeve. The piston assembly is pressed down by the second trigger block to drive the first piston to generate compressed air in the first sleeve, which is used to drive the protective assembly to be perpendicular to the detection plate.

[0018] In one possible technical solution, the protective component further includes:

[0019] A gas output pipe is installed on the trigger assembly and connected to the first sleeve of the trigger assembly for receiving compressed air;

[0020] Two sets of protection units, each set of protection units includes:

[0021] A branch pipe is connected to the gas output pipe, and a piston is installed inside the branch pipe;

[0022] A protective rod is rotatably mounted on the detection plate, and each protective rod is connected to a transmission gear.

[0023] The drive assembly, mounted on the trigger assembly, has a rack and a top post. The rack is connected to the top post and meshes with the transmission gear. The top post is connected to the piston portion. It receives compressed air to drive the transmission gear to rotate the protective rod.

[0024] In one possible technical solution, the piston assembly further includes:

[0025] A first mounting plate is mounted on the detector plate;

[0026] The first sleeve is installed on the first mounting plate;

[0027] The first piston is installed inside the first sleeve;

[0028] A push rod is connected to the first piston and extends out of the first sleeve;

[0029] The connecting post is installed on the first mounting plate;

[0030] A connecting sleeve is nested onto the connecting post;

[0031] A displacement block is installed at the end of the connecting sleeve that is away from the connecting post;

[0032] A trigger rod is installed on one side of the displacement block. The trigger rod is located directly below the second trigger block. The second trigger block presses down on the trigger rod to drive the displacement block to push the push rod to squeeze the first piston and form compressed air, which is used to drive the protective assembly to be perpendicular to the detection plate.

[0033] In one possible technical solution, the driving component further includes:

[0034] The second mounting plate is mounted on the detector plate.

[0035] Two support plates are installed on the second mounting plate;

[0036] Two guide rods connect two support plates, and a sliding block is fitted on each guide rod. The support plates and the guide rods form a rectangular area to restrict the vertical displacement of the sliding block.

[0037] A rack is connected to the sliding block and meshes with the transmission gear;

[0038] The top post is connected to the rack, and the top post away from the rack is connected to the piston part. Compressed air pushes the top post and rack to move, thereby driving the transmission gear to rotate the protective rod.

[0039] In one possible technical solution, a restoring spring is further fitted onto the guide rod to connect the sliding block and the support plate, so that the guide rod is parallel to the detection plate when no external force is applied.

[0040] In one possible technical solution, the motor drive mechanism further includes:

[0041] The motor is fixedly mounted on the first mounting bracket;

[0042] The second mounting bracket is rotatably mounted on the first mounting bracket;

[0043] The support rod is mounted on the second mounting bracket.

[0044] In one possible technical solution, the detector plate is further provided with an exhaust housing on one side. The exhaust housing is a closed cuboid housing that communicates with the gas source output component. An air outlet is provided on the side wall to receive gas and blow it into the area inside the detector plate to remove impurities from the surface of the detector plate and improve the accuracy of the inspection.

[0045] In one possible technical solution, the gas source output component further includes:

[0046] The second sleeve is installed on one side of the displacement block, and the second sleeve is located on one side of the trigger rod;

[0047] An air intake pipe is provided on the second sleeve near the displacement block;

[0048] The fixing rod has one end connected to the first mounting plate and the other end extending through the displacement block into the second sleeve.

[0049] The second piston is installed inside the second sleeve and connected to the fixed rod;

[0050] A connecting pipe has one end passing through and connected to the second piston, and the other end extending into the exhaust housing to provide a gas source.

[0051] In one possible technical solution, ball bearings are further provided on the peripheral side of the upper surface of the probe plate, which can reduce friction when the probe plate 20 slides in contact with the bottom of the bed board.

[0052] The flat panel detector of the movable X-ray machine according to an embodiment of the present invention has the following beneficial effects:

[0053] During use, when the patient is standing to take a chest X-ray, the motor drives the second mounting bracket to deflect, and the patient stands between the probe plate and the transmitter. When the patient needs to lie flat on the bed board for the chest X-ray, the height of the probe plate is adjusted by the lifting mechanism so that the probe plate can pass through the bottom of the bed board, which can meet the patient's examination needs and select the appropriate imaging method according to the patient's physical condition.

[0054] When a patient with a chest cavity needs to lie flat on the bed for imaging, the first protective bar deflects, and similarly causes the second protective bar to deflect. After the first and second protective bars deflect and stand upright on both sides of the bed, they protect the patient with a chest cavity and facilitate the safe conduct of the imaging.

[0055] When the displacement block is reset, the gas in the second sleeve enters the exhaust housing through the connecting pipe, and then exits through the air outlet on the wall of the exhaust housing, thereby cleaning the surface of the detection plate with air, removing impurities from the surface of the detection plate, and improving the accuracy of the inspection.

[0056] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0078] Example 1

[0079] like Figures 1 to 8 As shown, this embodiment provides a flat panel detector for a portable X-ray machine, mounted on one side of a bed board, comprising:

[0080] 10 movable seats;

[0081] A lifting mechanism 110 is installed on the movable seat 10. In this embodiment, the lifting mechanism 110 can be an electric telescopic rod device to adjust the height of the flat panel detector.

[0082] A first mounting bracket 120 is mounted on the lifting mechanism 110; a motor drive mechanism and a second mounting bracket 122 are mounted on the first mounting bracket 120; the second mounting bracket 122 is connected to the output shaft of the motor drive mechanism, and the motor drive mechanism drives the second mounting bracket 122 to rotate vertically.

[0083] The transmitter 130 is mounted on the second mounting bracket 122;

[0084] The detector plate 20 is mounted on the second mounting bracket 122 and is arranged parallel to the transmitter 130;

[0085] Protective components 30 are installed on both sides of the detection plate 20;

[0086] The trigger component is installed on the detection plate 20. When the detection plate 20 is parallel to the bed board, the lifting mechanism 110 raises and lowers the trigger component to abut against the bed board, thereby generating compressed air to make the protective component 30 perpendicular to the detection plate 20.

[0087] It should be noted that, in this embodiment, the triggering component includes:

[0088] The support plate 401 is installed on the detection plate 20;

[0089] The first trigger block 402 is elastically connected to the support plate 401. It should be noted that, in this embodiment, the first trigger block 402 and the support plate 401 are connected by a buffer 405, wherein the buffer 405 is a spring.

[0090] The second trigger block 403 is installed on the first trigger block 402. It should be noted that in this embodiment, both the first trigger block 402 and the second trigger block 403 are triangular wedge blocks, which facilitates linkage with other components.

[0091] A piston assembly, mounted on the detector plate 20 and located below the second trigger block 403, includes:

[0092] The first mounting plate 4040 is mounted on the detector plate 20;

[0093] The first sleeve 4041 is installed on the first mounting plate 4040;

[0094] The first piston 4042 is installed inside the first sleeve 4041;

[0095] Push rod 4043 is connected to the first piston 4042 and extends out of the first sleeve 4041;

[0096] The connecting post 4044 is installed on the first mounting plate 4040;

[0097] Connecting sleeve 4045 is nested on connecting post 4044;

[0098] The shifting block 4046 is installed at the end of the connecting sleeve 4045 away from the connecting post 4044;

[0099] A trigger rod 4047 is installed on one side of the displacement block 4046. The trigger rod 4047 is located directly below the second trigger block 403. The second trigger block 403 presses down on the trigger rod 4047 to drive the displacement block 4046 to push the push rod 4043 to squeeze the first piston 4042 and generate compressed air. This compressed air is used to drive the protective component 30 to be perpendicular to the detection plate 20, thereby protecting the patient in the chest cavity and facilitating the safe conduct of the detection and imaging.

[0100] It should be noted that, in this embodiment, the protective component 30 includes:

[0101] Gas output pipe 310 is installed on the trigger assembly and connected to the first sleeve 4041 of the trigger assembly for receiving compressed air;

[0102] Two sets of protection units, each set of protection units includes:

[0103] A branch pipe 320 is connected to the gas output pipe 31, and a piston is installed inside the branch pipe 320;

[0104] Protective rods are rotatably mounted on the detection plate 20, and each protective rod is connected to a transmission gear 330. The protective rods include:

[0105] The first protective rod 331 is installed on one side of the detection plate 20;

[0106] The second protective rod 332 is installed on the other side of the detection plate 20. The protective rod is connected to the transmission gear 330 through the rotating shaft 333. In the initial state, the first protective rod 331 and the second protective rod 332 are in a horizontal state.

[0107] A drive assembly, mounted on the trigger assembly, has a rack 343 and a push pin 344. The rack 343 is connected to the push pin 344 and meshes with the transmission gear 330. The push pin 344 is connected to the piston portion. It receives compressed air to drive the transmission gear 330 to rotate the protective rod. The drive assembly includes:

[0108] The second mounting plate 340 is mounted on the detection plate 20.

[0109] Two support plates are installed on the second mounting plate 340. In this embodiment, the support plates include a first support plate 3411 and a second support plate 3412, wherein the first support plate 3411 and the second support plate 3412 are symmetrically arranged on the second mounting plate 340.

[0110] Two guide rods 342 connect two support plates. A sliding block is sleeved on each guide rod 342. The support plates and the guide rods 342 form a rectangular area to limit the vertical displacement of the sliding block.

[0111] The rack 343 is connected to the sliding block and meshes with the transmission gear 330;

[0112] The top post 344 is connected to the rack 343. The top post 344, which is away from the rack 343, is connected to the piston part. Compressed air pushes the top post 344 and the rack 343 to move so as to drive the transmission gear 330 to drive the protective rod to flip.

[0113] It should be noted that, in this embodiment, a restoring spring is sleeved on the guide rod 342 to connect the sliding block and the support plate, so that the guide rod 342 is parallel to the detection plate 20 when no external force is applied.

[0114] It should be noted that, in this embodiment, a restoring spring is fitted on the connecting post 4044 and the connecting sleeve 4045 between the first mounting plate 4040 and the shifting block 4046. Under no external force, the end of the trigger rod 4047, which is away from the shifting block 4046, is located to the right of the lowest point of the second trigger block 403, so that the trigger rod 4047 can be moved when the second trigger block 403 is pressed down.

[0115] It should be noted that, in this embodiment, the motor drive mechanism includes:

[0116] Motor 121 is fixedly mounted on the first mounting bracket 120;

[0117] The second mounting bracket 122 is rotatably mounted on the first mounting bracket 120;

[0118] The support rod 123 is mounted on the second mounting bracket 122.

[0119] The specific working principle of this invention is as follows:

[0120] During use, when the patient is standing for chest imaging, motor 121 drives the second mounting bracket 122 to deflect, positioning the patient between the probe plate 20 and the transmitter 130. When the patient needs to lie flat on the bed for imaging, the height of the probe plate 20 is adjusted via the lifting mechanism 110, allowing it to pass under the bed. When the probe plate 20 passes under the bed, the bottom of the bed abuts against the first trigger block 402, causing it to move downwards. Then, the bottom slope of the second trigger block 403 abuts against the end of the trigger rod 4047, causing the displacement block 4046 to move along the connecting post 4044. The direction moves towards the first sleeve 4041, then the shift block 4046 abuts against the push rod 4043, thereby pushing the first piston 4042 to move inside the first sleeve 4041, thereby squeezing the gas inside the first sleeve 4041 into the gas output pipe 310. Then the gas flows through the branch pipe 320, thereby pushing the top column 344 and the rack 343 to move upward, thereby driving the first protective rod 331 to deflect. Similarly, it drives the second protective rod 332 to deflect. After the first protective rod 331 and the second protective rod 332 deflect and stand upright on both sides of the bed board, they protect the patient in the chest cavity and facilitate the safe conduct of the examination and imaging.

[0121] The flat panel detector of the movable X-ray machine according to an embodiment of the present invention has the following beneficial effects:

[0122] During use, when the patient is standing to take a chest X-ray, the motor drives the second mounting bracket to deflect, and the patient stands between the probe plate and the transmitter. When the patient needs to lie flat on the bed board for the chest X-ray, the height of the probe plate is adjusted by the lifting mechanism so that the probe plate can pass through the bottom of the bed board, which can meet the patient's examination needs and select the appropriate imaging method according to the patient's physical condition.

[0123] When a patient with a chest cavity needs to lie flat on the bed for imaging, the first protective bar deflects, and similarly, the second protective bar deflects. After the first and second protective bars deflect and stand upright on both sides of the bed, they protect the patient with a chest cavity and facilitate the safe conduct of the imaging.

[0124] Example 2

[0125] like Figures 1 to 8 As shown, this embodiment further improves upon embodiment 1, providing a flat panel detector for a movable X-ray imaging machine, mounted on one side of a bed board, comprising:

[0126] 10 movable seats;

[0127] A lifting mechanism 110 is installed on the movable seat 10. In this embodiment, the lifting mechanism 110 can be an electric telescopic rod device to adjust the height of the flat panel detector.

[0128] A first mounting bracket 120 is mounted on the lifting mechanism 110; a motor drive mechanism and a second mounting bracket 122 are mounted on the first mounting bracket 120; the second mounting bracket 122 is connected to the output shaft of the motor drive mechanism, and the motor drive mechanism drives the second mounting bracket 122 to rotate vertically.

[0129] The transmitter 130 is mounted on the second mounting bracket 122;

[0130] The detector plate 20 is mounted on the second mounting bracket 122 and is arranged parallel to the transmitter 130. An exhaust housing 200 is provided on one side of the detector plate 20. The exhaust housing 200 is a closed cuboid housing. Multiple air outlets are opened on the side wall of the exhaust housing 200 and are arranged at uniform intervals.

[0131] Protective components 30 are installed on both sides of the detection plate 20;

[0132] The trigger component is installed on the detection plate 20. When the detection plate 20 is parallel to the bed board, the lifting mechanism 110 raises and lowers the trigger component to abut against the bed board, thereby generating compressed air to make the protective component 30 perpendicular to the detection plate 20.

[0133] The gas source output component is connected to the exhaust housing 200 and is used to receive gas and deliver the gas to the exhaust housing 200 to blow air into the area inside the detector plate 20, remove impurities from the surface of the detector plate 20, and improve the accuracy of the inspection.

[0134] It should be noted that, in this embodiment, the gas source output component includes:

[0135] The second sleeve 500 is installed on one side of the shift block 4046, and the second sleeve 500 is located on one side of the trigger rod 4047;

[0138] The second piston 503 is installed inside the second sleeve 500 and connected to the fixed rod 502;

[0139] The connecting pipe 504 has one end passing through and connected to the second piston 503, and the other end extending into the exhaust housing 200 to provide an air source.

[0140] It should be noted that, in this embodiment, ball bearings 210 are provided on the periphery of the upper surface of the probe plate 20, which can reduce friction when the probe plate 20 slides in contact with the bottom of the bed board.

[0141] In this embodiment, when the shift block 4046 moves along the direction of the connecting column 4044 toward the direction of the first sleeve 4041, the gas enters the second sleeve 500 through the air inlet pipe 501. When the shift block 4046 is reset, the gas in the second sleeve 500 enters the exhaust housing 200 through the connecting pipe 504, and then is discharged through the air outlet on the side wall of the exhaust housing 200, thereby cleaning the surface of the detection plate 20 with air blowing, removing impurities from the surface of the detection plate 20, and improving the accuracy of the inspection.

[0142] The flat panel detector of the movable X-ray machine according to an embodiment of the present invention has the following beneficial effects:

[0143] During use, when the patient is standing to take a chest X-ray, the motor drives the second mounting bracket to deflect, and the patient stands between the probe plate and the transmitter. When the patient needs to lie flat on the bed board for the chest X-ray, the height of the probe plate is adjusted by the lifting mechanism so that the probe plate can pass through the bottom of the bed board, which can meet the patient's examination needs and select the appropriate imaging method according to the patient's physical condition.

[0144] When a patient with a chest cavity needs to lie flat on the bed for imaging, the first protective bar deflects, and similarly causes the second protective bar to deflect. After the first and second protective bars deflect and stand upright on both sides of the bed, they protect the patient with a chest cavity and facilitate the safe conduct of the imaging.

[0145] When the displacement block is reset, the gas in the second sleeve enters the exhaust housing through the connecting pipe, and then is discharged through the air outlet on the wall of the exhaust housing, thereby cleaning the surface of the detection plate with air, removing impurities from the surface of the detection plate, and improving the accuracy of the inspection.
