Description

Technical Field

[0001] This invention belongs to the field of medical testing technology, specifically a vehicle-mounted medical imaging device. Background Technology

[0002] An X-ray machine is a device that generates X-rays. It mainly consists of an X-ray tube, an X-ray machine power supply, and control circuitry. The X-ray tube is composed of a cathode filament, an anode target, and a vacuum glass tube. The X-ray machine power supply can be divided into two parts: a high-voltage power supply and a filament power supply. The filament power supply is used to heat the filament. The high-voltage output terminals of the high-voltage power supply are clamped at both ends of the cathode filament and the anode target, providing a high-voltage electric field that accelerates the active electrons on the filament towards the anode target, forming a high-speed electron stream. After bombarding the anode target surface, 99% of the electrons are converted into heat, and 1% is converted into X-rays due to bremsstrahlung radiation. Currently, X-ray machines are often used in mobile medical testing vehicles to examine patients with scoliosis.

[0003] Currently, when performing X-ray imaging examinations on patients with scoliosis in mobile medical testing vehicles, vehicle-mounted X-ray machines are often used. The existing procedures for examining the affected side with mobile medical X-ray machines typically involve the patient standing on a support platform with their arms hanging naturally at their sides. The X-ray machine is then moved up and down and rotated to take images of the patient's front and side views. However, due to the limited space in the mobile medical testing vehicle, and the fact that the X-ray machine rotates when the patient is not in the correct position, it can cause the X-ray machine to impact and squeeze the patient, potentially leading to injury. Therefore, a mobile medical imaging device is proposed to address the problems mentioned in the background section. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention improves safety when examining the affected side by utilizing the cooperation between the first gear, supporting frustum, movable pedal, and U-shaped handrail. When the patient stands on the movable pedal and holds the U-shaped handrail, the movable pedal presses down the limiting column, causing one end of the limiting column to disengage from the circular hole. Simultaneously, the lower outer surface of the limiting column is placed inside the circular hole. The motor then rotates the second gear clockwise, causing the first gear to move along the arc groove and engage with the fourth gear. Due to the limiting effect of the arc groove and the rotation of the second gear, the fourth gear rotates the supporting frustum. The motor then stops, and the engagement between the second ball bearing and the inner cavity of the fourth gear fixes the position of the supporting frustum. This solves the problem of patient injury caused by inaccurate positioning and the rotation of the X-ray machine mechanism. This invention utilizes the cooperation between the X-ray machine mechanism, top frame, threaded rod, and third gear to enable the device to facilitate image detection of the patient's upper body. By reversing the operation of the power motor and simultaneously operating the X-ray machine mechanism, the power motor will rotate in the opposite direction, simultaneously driving the first gear to reset along the arc groove and engage with the third gear. Subsequently, the rotation of the second gear will drive the third gear to rotate through the first gear, thereby causing the threaded rod to rotate. This causes the movable frame to move the X-ray machine mechanism downward, at which point the X-ray machine mechanism will perform X-ray image detection on the patient's upper body. This invention, through the cooperation of structures such as the piston block, pull rope, connecting pipe, and guide shaft, enables the device to prevent the U-shaped handrail from obstructing the patient during X-ray imaging. As the movable frame moves downward, it also moves the top end of the pull rope downward. At this time, due to the guiding effect of the guide shaft, the bottom end of the pull rope moves the piston block upward. At this time, the fifth elastic spring is compressed, and the air pressure in the inner cavity of the second cylinder below the piston block is reduced. Through the connecting pipe, the pressure inside the first cylinder and the cylindrical sleeve is reduced, thereby causing the U-shaped handrail to move downward and compressing the third elastic spring. This prevents the U-shaped handrail from obstructing the patient's upper body during X-ray imaging. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 10As shown, the present invention provides a vehicle-mounted medical imaging device, including a protective shell 1, a refrigerator 22, a water basin 23, a seat 24, an outward-opening window 25, a changing area 26, and a testing vehicle body 27. A first cylinder 3 is fixedly connected to the bottom of the inner cavity of the protective shell 1. A supporting frustum 2 is movably engaged with the top of the first cylinder 3. A ring frame 4 is fixedly connected to the bottom of the inner cavity of the first cylinder 3. A spring 5 is fixedly connected to the inner cavity of the ring frame 4. A first ball bearing 6 and a second ball bearing 7 are respectively movably engaged at equal angles in the middle and top cavities of the first cylinder 3. A first elastic spring 8 is fixedly connected at equal angles in the top cavity of the first cylinder 3. The front and rear ends of the inner cavity supporting the top of the truncated cone 2 are movably connected to movable pedals 9. The bottom of the movable pedals 9 is fixedly connected to a limiting post 10. A second elastic spring 11 is sleeved on the outer surface of the limiting post 10. A circular hole 12 is opened at the top of the ring frame 4 directly below the limiting post 10. Arc-shaped grooves 13 that mate with the circular hole 12 are opened on both sides of the top of the ring frame 4. The front and rear ends of the inner cavity supporting the truncated cone 2 are fixedly connected to cylindrical sleeves 15. A U-shaped handrail 16 is movably connected to the inner cavity of the cylindrical sleeve 15. The bottom ends of the U-shaped handrail 16 are fixedly connected to a third elastic spring 17. The bottom of the inner cavity of the protective shell 1 is... A gear mechanism 18 is fixedly connected to the protective shell 1. Height adjustment mechanisms 20 are fixedly connected to the front and rear ends of the bottom of the inner cavity of the protective shell 1, away from the supporting frustum 2. A handrail mechanism 21 is fixedly connected to the bottom of the inner cavity of the protective shell 1, away from the supporting frustum 2. A fixed pedal 19 is fixedly connected to the top of the protective shell 1, away from the height adjustment mechanism 20. When the patient stands on the movable pedal 9 and holds the U-shaped handrail 16, the movable pedal 9 presses down on the limiting post 10, causing one end of the limiting post 10 to disengage from the circular hole 12. Simultaneously, the lower outer surface of the limiting post 10 will be inside the circular hole 12. In the process, the operating motor 184 causes the second gear 185 to rotate clockwise, which in turn drives the first gear 183 to move along the arc groove 182 and engage with the fourth gear 187. Due to the limiting effect of the arc groove 182 and the rotation of the second gear 185, the fourth gear 187 will cause the supporting frustum 2 to rotate. Subsequently, the operating motor 184 stops running. At the same time, the engagement between the second ball bearing 7 and the inner cavity of the fourth gear 187 will fix the position of the supporting frustum 2, thereby solving the problem of patient injury caused by inaccurate positioning and rotation of the X-ray machine mechanism 2006.

[0020] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the gear set mechanism 18 includes a gear carrier 181 and a third gear 186. The bottom of the gear carrier 181 is fixedly connected to the protective housing 1. The top of the gear carrier 181 has an arc groove 182. The inner cavity of the arc groove 182 is movably connected to a first gear 183. The bottom of the inner cavity of the protective housing 1 is fixedly connected to a power motor 184 located behind the gear carrier 181. The output shaft of the power motor 184 is fixedly connected to a second gear 185. The bottom of the supporting frustum 2 is fixedly connected to a fourth gear 187. The rotating shaft of the arc groove 182 cooperates with the arc groove 182. The third gear 186 is fixedly sleeved on the first gear. At the bottom of the outer surface of 183, the first gear 183 meshes with the third gear 186, the second gear 185 meshes with the first gear 183, and the second gear 185 and the third gear 186 do not contact each other. The lower middle part of the inner cavity of the fourth gear 187 is also movably sleeved on the outer surface of the first cylinder 3. The second gear 185 and the fourth gear 187 do not contact each other, and the first gear 183 meshes with the fourth gear 187. Through the meshing between the arc groove 182 and the first gear 183, and by controlling the rotation of the power motor 184 in different directions, the third gear 186 and the fourth gear 187 will be driven to rotate respectively. It is worth noting that the circle of the arc groove 182 is the axis of the power motor 184.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9As shown, the height adjustment mechanism 20 includes a limiting rod 2001. The bottom of the limiting rod 2001 is fixedly connected to the protective shell 1. A connecting block 2002 and a top frame 2004 are fixedly connected to the middle and bottom of the outer surface of the limiting rod 2001, respectively. A threaded rod 2003 is movably connected to the inner cavity of the middle part of the connecting block 2002. A movable frame 2005 is threadedly connected to the upper outer surface of the threaded rod 2003. An X-ray machine mechanism 2006 is fixedly connected to the side of the movable frame 2005 near the supporting frustum 2. A buffer plate 2007 and a fourth elastic spring 2008 located above the connecting block 2002 are also sleeved on the middle part of the limiting rod 2001. The tops of the limiting rod 2001 and the threaded rod 2003 both penetrate the protective shell 1 and extend to the top of the protective shell 1. One end of the bottom of the threaded rod 2003 penetrates the protective shell 1 and extends into the interior of the protective shell 1, movably connecting to the inner cavity of the protective shell 1. The top frame 2004... The bottom of 004 ​​is movably connected to the top of the threaded rod 2003. The front and rear ends of the inner cavity of the movable frame 2005 are movably connected to the outer surfaces of the front and rear limit rods 2001, respectively. The outer surface of the threaded rod 2003 is located in the inner cavity of the buffer plate 2007 and the two do not contact each other. One end of the bottom is fixedly connected to the connecting block 2002. By running the reverse power motor 184 and running the X-ray machine mechanism 2006 at the same time, the power motor 184 will rotate in the reverse direction, and at the same time drive the first gear 183 to reset along the arc groove 182 and cooperate with the third gear 186. Then the rotation of the second gear 185 will drive the third gear 186 to rotate through the first gear 183, thereby causing the threaded rod 2003 to rotate, so that the movable frame 2005 drives the X-ray machine mechanism 2006 to move downward. At this time, the X-ray machine mechanism 2006 will perform X-ray image detection on the upper body of the patient. It is worth noting that when the movable frame 2005 moves downward, it will also come into contact with the buffer plate 2007, causing the bottom of the buffer plate 2007 to compress the fourth elastic spring 2008. This serves to buffer the movable frame 2005 when it descends too far, thus providing a buffering and protection effect for the movable frame 2005 and the X-ray machine mechanism 2006.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9As shown, the handrail mechanism 21 includes a second cylinder 2101. The bottom of the second cylinder 2101 is fixedly connected to the protective shell 1. The handrail mechanism 21 passes through the protective shell 1 and extends above it. A piston block 2102 is movably connected to the inner cavity of the second cylinder 2101. A pull rope 2103 and a fifth spring 2104 are fixedly connected to the top of the piston block 2102. A guide shaft 2105 is hinged to the inner cavity of the bottom of the top frame 2004 on the side away from the supporting frustum 2. The second cylinder 2101... 1. Connecting pipes 2106 are fixedly connected to the inner cavities of the bottom front and rear ends. A fifth elastic spring 2104 is sleeved on the outer surface of the pull rope 2103. One top end of the pull rope 2103 is fixedly connected to the second cylinder 2101. The top end of the pull rope 2103 passes through the top of the second cylinder 2101 and extends to the top of the second cylinder 2101. One top end of the pull rope 2103 is fixedly connected to the movable frame 2005. The pull rope 2103 contacts the upper surface of the guide shaft 2105. Connecting pipe 2 One end of 106 near the second cylinder 2101 is connected to the first cylinder 3 through the inner cavity of the first cylinder 3 and extends into the interior of the first cylinder 3. The inner cavity of the second cylinder 2101 is connected to the inner cavity of the cylindrical sleeve 15 through the connecting pipe 2106 and the first cylinder 3. As the movable frame 2005 moves downward, it also drives one end of the top of the pull rope 2103 to move downward. At this time, due to the guiding effect of the guide shaft 2105, one end of the bottom of the pull rope 2103 drives the piston block 2102 to move downward. When the X-ray machine moves upward, the fifth spring 2104 will be compressed, and the air pressure in the inner cavity of the second cylinder 2101 below the piston block 2102 will decrease. This will reduce the pressure inside the first cylinder 3 and the cylindrical sleeve 15 through the connecting pipe 2106, causing the U-shaped handrail 16 to move downward and compress the third spring 17. This prevents the U-shaped handrail 16 from obstructing the upper body of the patient when the X-ray machine mechanism 2006 is examining the patient. It is worth noting that after the X-ray machine mechanism 2006 moves downward, if the power motor 184 is run to make the second gear 185 rotate clockwise, the second gear 185 will drive the first gear 183 to move along the arc groove 182, but will not drive the third gear 186 to rotate in the opposite direction. At this time, the power motor 184 needs to be run to make the second gear 185 rotate and drive the first gear 183 to move to the middle of the arc groove 182. At this time, due to the elastic force of the fifth spring 2104, the piston block 2102 will move downward, and at the same time, one end of the bottom of the pull rope 2103 will move downward. At this time, one end of the top of the pull rope 2103 will move upward under the guidance of the guide shaft 2105, thereby pulling the movable frame 2005 and the X-ray machine mechanism 2006 upward and resetting. It is worth noting that the piston block 2102, in conjunction with the inner cavity of the second cylinder 2101 and the elastic force of the fifth spring 2104, will produce a damping effect. At this time, the piston block 2102 descends slowly, and the moving frame 2005 drives the X-ray machine mechanism 2006 to rise slowly, thereby preventing the X-ray machine mechanism 2006 from rising rapidly and causing damage to the internal components of the X-ray machine mechanism 2006.

[0023] like Figure 10 As shown, the protective shell 1 is located in the middle of the interior of the inspection vehicle body 27, the changing area 26 is located at the rear end of the protective shell 1, the seat 24 is located on one side of the changing area 26 inside the inspection vehicle body 27, the refrigerator 22 is located on the side of the inspection vehicle body 27 away from the changing area 26, the water basin 23 is located on the side of the inspection vehicle body 27 away from the refrigerator 22 and away from the changing area 26, and the outward-opening window 25 is located on the side wall of the inspection vehicle body 27, and the outward-opening window 25 is located on the side of the seat 24 inside the inspection vehicle body 27 away from the protective shell 1. It is worth noting that doctors can use the outward-opening window 25 to conduct test strip tests on people outside the vehicle. At the same time, the vehicle is equipped with a refrigerator 22 for reagents and test samples, as well as a water basin 23 for medical staff to disinfect. When conducting imaging tests, patients need to first enter the changing area 26, take off their clothes, and enter the protective shell 1 to have their pictures taken.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 Diagram and Figure 8As shown, one end of the top of the first ball bearing 6 is in contact with the bottom of the supporting frustum 2. The end of the first spring 8 away from the second ball bearing 7 is fixedly connected to the supporting frustum 2. The end of the second ball bearing 7 away from the first spring 8 is engaged with the inner cavity of the fourth gear 187. The top of the ring frame 4 is not in contact with the bottom of the supporting frustum 2. The bottom of the outer surface of the supporting frustum 2 penetrates the top of the ring frame 4 and extends into the interior of the ring frame 4. The end of the spring 5 away from the ring frame 4 is fixedly connected to the supporting frustum 2. The bottom of the outer surface of the limiting post 10 is engaged with the inner cavity of the circular hole 12. The top and bottom of the second spring 11 are fixedly connected to the movable pedal 9 and the supporting frustum 2, respectively. The arc of the arc groove 13 is ninety degrees. The inner surface of the 13 is engaged with the outer surface of the lower part of the limiting column 10. The third elastic spring 17 is movably connected inside the cylindrical sleeve 15. One end of the bottom of the third elastic spring 17 is fixedly connected to the spring 5. By rotating the supporting frustum 2, the spring 5 will be compressed. After the test is completed, the person needs to stand on the fixed pedal 19 first, so that the patient can quickly leave the moving pedal 9. At this time, due to the lack of the patient's gravity, the spring 5 will cause the supporting frustum 2 to rotate and reset. At this time, due to the elasticity of the first elastic spring 8, the second ball 7 and the fourth gear 187 are engaged, thus preventing the spring 5 from causing the supporting frustum 2 to reset too quickly.

[0025] Working principle and usage process of this invention: First, the patient stands on the fixed pedal 19. After being reminded by medical staff, the patient stands on the movable pedal 9. At this time, the patient holds the U-shaped handrail 16. Due to the patient's own weight, the movable pedal 9 will press the limiting post 10 downward, causing one end of the limiting post 10 to disengage from the round hole 12. At the same time, the outer surface of the lower part of the limiting post 10 will be inside the round hole 12. At this time, the motor 184 will rotate the second gear 185 clockwise, which will drive the first gear 183 to move along the arc groove 182 and engage with the fourth gear 187. Due to the limiting of the arc groove 182 and the rotation of the second gear 185, the fourth gear 187 will drive the supporting frustum 2 to rotate. When the lower part of the outer surface of the arc groove 182 contacts the side wall of the inner cavity of the arc groove 13 away from the round hole 12, the motor 184 will stop running. At the same time, due to the engagement between the second ball 7 and the inner cavity of the fourth gear 187, the position of the supporting frustum 2 will be fixed. Then, the reverse operation of the power motor 184, along with the operation of the X-ray machine mechanism 2006, will cause the power motor 184 to rotate in the opposite direction. This will drive the first gear 183 to reset along the arc groove 182 and engage with the third gear 186. Subsequently, the rotation of the second gear 185 will drive the third gear 186 to rotate through the first gear 183, thereby causing the threaded rod 2003 to rotate. This will cause the movable frame 2005 to move the X-ray machine mechanism 2006 downward. At this time, the X-ray machine mechanism 2006 will perform X-ray imaging on the patient's upper body, completing the operation. As the movable frame 2005 moves downward, it also drives the top end of the pull rope 2103 to move downward. At this time, due to the guiding effect of the guide shaft 2105, the bottom end of the pull rope 2103 drives the piston block 2102 to move upward. At this time, the fifth elastic spring 2104 will be compressed, and the air pressure in the inner cavity of the second cylinder 2101 below the piston block 2102 will decrease. Through the connecting pipe 2106, the pressure inside the first cylinder 3 and the cylindrical sleeve 15 will decrease, thereby causing the U-shaped handrail 16 to move downward and the third elastic spring 17 to be compressed. This prevents the U-shaped handrail 16 from obstructing the upper body of the patient when the X-ray machine mechanism 2006 is examining the patient.
