Description

Technical Field

[0001] This invention relates to an intelligent radiation protection device for DSA catheter beds, belonging to the field of medical device technology. Background Technology

[0002] Digital subtraction angiography (DSA) is considered the gold standard for diagnosing ischemic vascular diseases. It uses X-rays emitted by DSA, combined with contrast agents, to visualize blood vessels, enabling diagnostic and therapeutic procedures. The application of DSA technology has significantly improved the detection rate of vascular diseases and provided an excellent platform for interventional therapy. Medical staff performing interventional procedures using DSA are among the hospital's radiation workers who receive the highest radiation doses. Generally, the radiation dose received by personnel performing interventional procedures is much higher than that of accelerator or radiology staff. Especially during interventional surgeries, the radiation dose received by the surgeon is even greater.

[0003] Currently, lead aprons are used clinically to protect operators from X-ray radiation, providing some protection. A complete lead apron typically weighs 5-8 kg, while interventional surgeons often perform several or even a dozen surgeries a day, with some complex procedures lasting several hours. Wearing a heavy lead apron for extended periods significantly increases the workload for surgeons, potentially leading to exhaustion and impacting their health. Lead aprons are not only heavy but also non-breathable, requiring surgeons to concentrate during operations, often resulting in profuse sweating and discomfort, hindering the smooth progress of the procedure. Furthermore, lead aprons only protect certain parts of the body; the face, arms, and lower legs are left unprotected, directly exposed to X-rays, causing significant harm to the operator. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an intelligent radiation protection device for DSA catheter beds.

[0005] The technical solution adopted in this invention is an intelligent radiation protection device for DSA catheterization bed, comprising: a protective chamber, a position adjustment system, and an intelligent control system; The protective cabin includes a front panel, side panels and a top panel. The side panels are rotatably connected to both sides of the front panel. The top panel is located above the front panel. The outer wall of the front panel is provided with an outwardly protruding observation window and an operating hole with a flexible protective sleeve. The edge of the top panel is provided with a downwardly extending folded edge. The position adjustment system enables the protective cabin to achieve position adjustment in three dimensions: circumferential adjustment around the operating table, longitudinal adjustment along the length of the operating table, and height adjustment perpendicular to the plane of the operating table. The intelligent control system includes a microcontroller, an in-cabin microphone, an external microphone, a touch switch, a drive module, and a distance sensor for detecting the distance from the bottom of the protective cabin to the ground, all electrically connected to the microcontroller. The drive module is connected to the position adjustment system and the opening and closing mechanism of the side panel. The microcontroller responds to the trigger signal of the touch switch or the voice command picked up by the in-cabin microphone or the external microphone to control the drive module to drive the position adjustment system or control the opening and closing of the side panel.

[0006] As a further aspect of the present invention, the position adjustment system includes: The circumferential adjustment unit includes a ring track fixed to the roof of the operating room and surrounding the operating table, a slider slidably connected to the ring track, and a circumferential drive mechanism for driving the slider to move along the ring track.

[0007] As a further embodiment of the present invention, the circumferential drive mechanism includes a rack disposed on the side of the annular track and a gear meshing with the rack and driven by a motor, the gear being disposed on the parallel track; the longitudinal adjustment mechanism includes a drive member and a ball screw, the ball screw being rotatably connected between the parallel tracks, the drive member driving the screw to rotate, and the nut moving linearly along the axial direction of the screw while the screw rotates; the height adjustment unit is a hydraulic rod, the hydraulic rod being fixed to the nut, and the piston end of the hydraulic rod being fixed to the top plate.

[0008] As a further aspect of the present invention, a microenvironment control system is also included. The microenvironment control system is electrically connected to the microcontroller.

The air vent is connected to the air outlets of the fresh air system and the air conditioning system through flexible pipes. A fan is installed inside the flexible pipes. A shadowless lamp and an ultraviolet disinfection lamp are installed on the top plate.

[0009] As a further aspect of the present invention, the microcontroller pre-stores a safety distance threshold. When the distance sensor detects that the distance between the lower edge of the protective cabin and the ground is equal to the safety distance threshold, the microcontroller controls the height adjustment unit to stop descending or reverse and ascend. When the external microphone or the internal microphone picks up a specific wake-up word and a door opening command, the microcontroller controls the displacement and direction of the sidewall.

[0010] As a further embodiment of the present invention, the side plate is rotatably connected to the front plate via a rotating shaft, the rotating shaft being driven by an opening and closing motor, and the opening and closing motor being electrically connected to the drive module.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0016] To further understand the invention, the technical solution will be further described below in conjunction with specific embodiments.

[0017] Example 1: As Figures 1-6 As shown, this embodiment provides an intelligent radiation protection device for a DSA catheterization bed, including a protective chamber, a position adjustment system and an intelligent control system. The DSA is installed on the roof of the operating room and located inside the circular track 20.

[0018] The protective cabin structure includes a front panel 1, side panels 2, and a top panel 3. The side panels 2 are rotatably connected to both sides of the front panel 1, and the top panel 3 is located above the front panel 1. The front panel 1 has a smaller curvature, while the side panels 2 have a larger curvature. The entire protective cabin is made of radiation-shielding materials, such as lead. An observation window 4 is provided on the upper part of the front side of the protective cabin, protruding outward from the front side. The observation window 4 is made of lead glass, which facilitates observation by doctors while blocking radiation. The cross-section of the observation window 4 is oblong, allowing doctors to easily extend their heads and observe not only forward but also along the side of the observation window 4. An operating hole 5 is also provided on the front panel 1 of the protective cabin, located below the observation window 4, for doctors to extend their hands out of the protective cabin for operation. A flexible protective sleeve 6, made of flexible protective material, is connected outward from the operating hole 5. The top plate 3 has a downward-extending folded edge 7. When the side plates 2 are closed, the cross-section of the three together is "D" shaped when viewed from above. The top of the side plate 2 fits into the folded edge 7 to form a radiation-proof seal, preventing radiation leakage from harming the human body.

[0019] The position adjustment system is used to adjust the protective cabin to a suitable position according to the needs of the surgery. It enables three-dimensional position adjustment of the protective cabin: the first dimension is circumferential adjustment around the operating table 12; the second dimension is adjustment of the distance between the protective cabin and the operating table along a plane parallel to the operating table; and the third dimension is adjustment of the height of the protective cabin to accommodate doctors of different heights. In other words, these are circumferential adjustment around the operating table 12, longitudinal adjustment along the length of the operating table 12, and height adjustment perpendicular to the plane of the operating table 12.

[0020] As one specific implementation of this embodiment, the position adjustment system includes: The circumferential adjustment unit includes an annular track 20 fixed to the roof of the operating room and surrounding the operating table 12, a slider 21 slidably connected to the annular track 20, and an annular drive mechanism for driving the slider 21 to move along the annular track 20. The longitudinal adjustment unit includes a parallel rail 22 connected to the slider 21, and a longitudinal drive mechanism that drives the protective cabin to move along the parallel rail 22. A height adjustment unit is connected between the longitudinal adjustment unit and the top of the protective cabin, and is used to drive the protective cabin to rise and fall; The circumferential drive mechanism, longitudinal drive mechanism, and height adjustment unit are all electrically connected to the drive module. The circumferential drive mechanism includes a rack 23 disposed on the side of the annular track 20 and a gear 24 meshing with the rack 23 and driven by a motor 25. The gear 24 is disposed on the parallel track 22. The longitudinal adjustment mechanism includes a drive component and a ball screw. The ball screw is rotatably connected between the parallel tracks 22. The drive component drives the screw to rotate, and while the screw rotates, the nut moves linearly along the axial direction of the screw. The height adjustment unit is a hydraulic rod 26, which is fixed to the nut. The piston end of the hydraulic rod 26 is fixed to the top plate 3.

[0021] The first dimension of adjustment is achieved through the sliding of gear 24 and rack 23. A circular track 20 is installed on the ceiling of the operating room, corresponding to the position of the operating table 12. A slider 21 is installed at the upper end of a parallel track 22, connecting the parallel track 22 to the circular track 20. The slider 21 can drive the lower parallel track 22 to slide along the circular track 20. A rack 23 is installed on the side of the circular track 20, and a gear 24 is installed on the upper side of the parallel track 22. A motor 25 drives the gear 24 to rotate, causing the slider 21 to slide along the circular track 20, thus achieving the first dimension of adjustment.

[0022] The adjustment in the second dimension is achieved through a ball screw, and the adjustment in the third dimension is achieved through a hydraulic rod 26.

[0023] The intelligent control system includes a microcontroller, and an internal microphone 8, an external microphone 9, a touch switch 10, a drive module, and a distance sensor 11 for detecting the distance from the bottom of the protective cabin to the ground, all electrically connected to the microcontroller. The drive module is connected to the position adjustment system and the opening and closing mechanism of the side panel 2. The microcontroller responds to the trigger signal from the touch switch 10 or the voice commands picked up by the internal microphone 8 or the external microphone 9, controlling the drive module to drive the position adjustment system or control the opening and closing of the side panel 2. The opening and closing mechanism is an opening and closing motor. The side panel 2 is rotatably connected to the front panel 1 via a rotating shaft driven by the opening and closing motor, which is electrically connected to the drive module. The two side panels 2 form the cabin door. The internal microphone 8 is located inside the protective cabin to pick up voice information inside the cabin, and the external microphone 9 is located outside the protective cabin to pick up voice information outside the cabin.

[0024] When a doctor wants to open the cabin door, there are two methods. One is to touch the touch switch 10. Upon receiving the touch signal, the touch switch 10 sends the information to the microcontroller, which then drives the opening / closing motor to open or close the side panels 2. The other method is for the doctor to control the door opening via voice. For example, a wake-up signal can be pre-set in the microcontroller, such as "Hello, Xiao X". When the doctor is outside the protective cabin, they can say, "Hello, Xiao X, please open the door." The external microphone 9 picks up the voice and transmits the voice signal to the microcontroller. Upon receiving the voice signal, the microcontroller drives the opening / closing motor to open the cabin door according to the instruction. Similarly, the internal microphone 8 inside the protective cabin picks up voice signals from inside the cabin and performs corresponding actions based on the content of the voice signal. For example, the voice signal "Hello, Xiao X, please move the protective cabin 10 centimeters to the left" can be used. After the microcontroller analyzes the voice signal, it drives the corresponding motor to complete the corresponding action.

[0025] Example 2: As Figures 1-6 As shown, this embodiment, based on embodiment 1, also includes a microenvironment control system. The microenvironment control system is electrically connected to the microcontroller. The microenvironment control system includes a temperature sensor 14, a humidity sensor 15, and an air vent on the top plate 3, all installed inside the protective cabin. The air vent is connected to the air outlets of the fresh air system and the air conditioning system via a flexible duct 16. A fan 17 is installed inside the flexible duct 16; in this embodiment, a silent fan 17 is used. A shadowless lamp 18 and an ultraviolet disinfection lamp 19 are installed on the top plate 3. The microcontroller pre-stores a safe distance threshold. When the distance sensor 11 detects that the distance between the lower edge of the protective cabin and the ground is equal to the safe distance threshold, the microcontroller controls the height adjustment unit to stop descending or reverse and rise. When the external microphone 9 or the internal microphone 8 picks up a specific wake-up word and a door opening command, the microcontroller controls the displacement and direction of the sidewall.

[0026] The microenvironment control system primarily regulates the temperature and humidity within the protective chamber. Since X-rays are emitted from the operating room, ionizing the air and producing harmful particles, the fresh air system replaces the air in the protective chamber, expelling these harmful particles and preventing harm to the patient. The air conditioning system regulates the temperature and humidity within the protective chamber. The shadowless lamp 18 provides the doctor with better visibility, ensuring that the line of sight within the protective chamber is consistent with that in the operating room, eliminating any sense of isolation. The ultraviolet disinfection lamp 19 disinfects the interior of the protective chamber. Temperature sensors 14 and humidity sensors 15 detect the temperature and humidity within the protective chamber. Simultaneously, the microcontroller is electrically connected to the fan 17, which, based on the detected temperature and humidity within the protective chamber, controls the fan 17 to regulate the temperature and humidity and refresh the air.

[0027] Example 3: This example discloses an electronic device, including: The memory is used to store computer programs and preset protective cabin control parameters, including a safe distance threshold, a wake-up word, and standard position coordinates. A processor, coupled to the memory, is used to read and execute the computer program to implement the intelligent control logic of the intelligent radiation protection device described in Embodiment 1 or 2; the processor is configured to: Receive the trigger signal from the touch switch 10 or the voice signal picked up by the cabin microphone 8 / exterior microphone 9; The voice signal is analyzed to identify the wake word and control commands; Drive signals are generated according to the control commands and sent to the position adjustment system, the side plate 2 opening and closing mechanism and the micro-environment control system. The input and output interfaces are respectively connected to the processor, the position adjustment system, the opening and closing mechanism of the side plate 2, the micro-environment control system, and various sensors for signal transmission and reception.

[0028] Meanwhile, this embodiment also discloses a computer-readable storage medium storing a computer program thereon. When the computer program is executed by a processor, it implements an intelligent anti-radiation protection control method, the method comprising the following steps: In response to the trigger signal of the touch switch 10 or the voice signal picked up by the in-cabin microphone 8 / out-of-cabin microphone 9, the voice signal is analyzed to identify the wake word and control commands; When an open or close command is detected, an opening / closing drive signal is generated to control the opening or closing of the side panel 2 of the protective cabin; When a position adjustment command is detected, the displacement and direction in the command are analyzed to generate a position adjustment signal to drive the protective cabin to perform circumferential adjustment around the operating table 12, longitudinal adjustment along the length of the operating table 12, or vertical height adjustment. The system acquires the detection data from the distance sensor 11 in real time. When the distance between the lower edge of the protective cabin and the ground or the operating table 12 is less than or equal to the preset safe distance threshold, it generates an emergency stop or recovery signal to prevent the protective cabin from continuing to descend. The system acquires the detection data from the cabin temperature and humidity sensor 15, and adjusts the speed of the fan 17 according to the detection data to maintain the set temperature and humidity range.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
