Abstract

This invention discloses an automatic lead door device with radiation monitoring and protection, comprising a door body, a radiation monitoring module, and a vertical locking mechanism. The radiation monitoring module includes an X-ray sensor and a microprocessor, both installed inside the door body. The X-ray sensor detects X-ray radiation received by the door body, and the microprocessor controls the opening and closing of the vertical locking mechanism, which is also installed inside the door body and locks the door at its bottom. This device ensures the door can be closed and locked during use, preventing situations where the door is not properly closed due to technicians' improper operation, allowing patients to easily open it.

Description

Technical Field

[0001] This invention belongs to the field of medical radiation equipment technology, specifically relating to an automatic lead door device with radiation monitoring and protection. Background Technology

[0002] X-rays are a stream of particles produced by the transition of electrons between two energy levels with a significant energy difference in atoms. They are electromagnetic waves with wavelengths between ultraviolet and gamma rays. X-rays have high penetrating power and can pass through many materials that are opaque to visible light, such as ink-paper and wood. These invisible rays can cause visible fluorescence in many solid materials, expose photographic film, and ionize air. X-rays were initially used for medical imaging and diagnostics, and X-ray crystallography. However, X-rays are also a type of radiation, including ionizing radiation, that is harmful to the human body.

[0003] The radiology department is an important auxiliary examination department in hospitals. In modern hospital construction, the radiology department is a department that integrates examination, diagnosis, and treatment. Many diseases in various clinical departments require examination through radiology equipment to achieve a clear diagnosis and auxiliary diagnosis. The equipment in the radiology department generally includes ordinary X-ray machines, computed tomography (CR) systems, direct digital radiography (DR) systems, computed tomography (CT) systems, magnetic resonance imaging (MRI) systems, digital subtraction angiography (DSA) systems, etc. The radiology department has always been a traditional and essential department in general hospitals, making great contributions to the hospital's medical care, scientific research, and teaching work. However, it also generates radiation during use. Therefore, hospital radiology departments are equipped with protective doors to block radioactive materials and prevent radiation from harming personnel.

[0004] However, the protective lead doors used in hospital radiology departments still have certain defects. For example, during use, if the technician does not operate the protective lead door according to regulations, the protective lead door may not be closed tightly and may be opened by the patient. Or, if the technician is busy completing the examination before finishing the scan, the protective lead door may be opened by mistake, resulting in X-ray leakage.

[0005] Based on this, the applicant is considering designing an automatic lead door device with radiation monitoring protection. Summary of the Invention

[0006] In view of the above problems, the present invention provides an automatic lead door device with radiation monitoring protection that overcomes or at least partially solves the above problems, the technical solution of which is as follows:

[0007] An automatic lead door device with radiation monitoring and protection includes a door body, a radiation monitoring module, and a vertical locking mechanism. The radiation monitoring module includes an X-ray sensor and a microprocessor. Both the X-ray sensor and the microprocessor are installed inside the door body. The X-ray sensor is used to detect X-ray radiation information received by the door body. The microprocessor is used to control the opening and closing of the vertical locking mechanism. The vertical locking mechanism is installed inside the door body and is used to lock the door body at the bottom.

[0008] Compared with the prior art, the automatic lead door device with radiation monitoring and protection of the present invention has the following advantages:

[0009] By incorporating X-ray sensors, a microprocessor, and a vertical locking mechanism, the door can be closed and locked during use. This prevents situations where the door is not closed properly due to technicians' improper operation, allowing patients to easily open it. It also prevents situations where technicians, busy completing the examination, open the door before the X-ray scan is finished, leading to X-ray leakage.

[0010] The aforementioned automatic lead door device with radiation monitoring and protection has the advantages of simple structure and easy implementation. It is suitable for installation and use in existing hospital radiology departments, and the cost of use is low, which can improve efficiency. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] In practical implementation: such as Figures 1-5 As shown, an automatic lead door device with radiation monitoring and protection includes a door body 100, a radiation monitoring module, and a vertical locking mechanism. The radiation monitoring module includes an X-ray sensor 210 and a microprocessor 220. Both the X-ray sensor 210 and the microprocessor 220 are installed inside the door body 100. The X-ray sensor 210 is used to detect the X-ray radiation information received by the door body 100, and the microprocessor 220 is used to control the opening and closing of the vertical locking mechanism. The vertical locking mechanism is installed inside the door body 100 and is used to lock the door body 100 at the bottom.

[0025] During implementation, a ground track is installed below the door body 100, and rollers are connected to the bottom of the door body 100, which can slide along the ground track.

[0026] Compared with the prior art, the automatic lead door device with radiation monitoring and protection of the present invention has the following advantages:

[0027] The X-ray sensor 210, microprocessor 220, and vertical locking mechanism ensure that the door 100 can be closed and locked during use. This prevents the door from being opened easily by the patient due to the technician's improper operation of the door 100. It also prevents the X-ray from being leaked because the technician is busy completing the examination and the X-ray scan is not finished.

[0028] The aforementioned automatic lead door device with radiation monitoring and protection has the advantages of simple structure and easy implementation. It is suitable for installation and use in existing hospital radiology departments, and the cost of use is low, which can improve efficiency.

[0029] In this embodiment, as Figures 2-5As shown, the vertical locking mechanism includes a first motor 310, a worm gear 320, a cam 330, and a locking assembly. The first motor 310, the worm gear 320, and the cam 330 are all installed inside the door body 100. The worm gear 320 is driven by the first motor 310. The non-protruding surface of the cam 330 has a worm gear structure. The cam 330 is driven by the worm gear structure. The locking assembly is installed inside the door body 100 and located below the cam 330. The locking assembly can be pushed downward by the cam 330 to below the door body 100.

[0030] In practice, the worm gear structure on the cam 330 engages with the worm 320 via a worm wheel and worm gear transmission, and the shaft of the first motor 310 is coaxially connected to the worm 320. This enhances the stability of the transmission structure.

[0031] In this way, by setting up the first motor 310, worm gear 320, cam 330 and locking component, the first motor 310 controls the cam 330 through the worm gear 320 to drive the locking component to move up and down. The locking structure and state change are relatively simple, and the stability and reliability are high.

[0032] In this embodiment, as Figures 2-5 As shown, the locking assembly includes a locking rod 341, a spring 342, and a bracket 343. The locking rod 341 is vertically disposed inside the door body 100. A push plate is provided at the top of the locking rod 341, and the top surface of the push plate abuts against the cam 330. The bracket 343 is fixedly installed inside the door body 100 and located below the push plate. One end of the spring 342 is connected to the bracket 343, and the other end is connected to the push plate. A first through hole is provided at the bottom of the door body 100, and the position of the first through hole corresponds to the bottom of the locking rod 341. The locking rod 341 can extend downward through the first through hole to the bottom of the door body 100.

[0033] In this way, the locking assembly consisting of the locking rod 341, spring 342 and bracket 343 enables the locking rod 341 to be reset by the bracket 343 and spring 342 after being pushed out by the cam 330. This achieves the pushing and retraction of the locking rod 341. The structure is relatively simple, the manufacturing cost is low, and the structure has high reliability, which is conducive to implementation.

[0034] During implementation, a limiting hole is provided inside the door body 100 at the position corresponding to the locking rod 341. The locking rod 341 passes through the limiting hole, and the limiting rod can stabilize the rod of the locking rod 341, so that the locking rod 341 does not deviate from the movement trajectory when it moves up and down.

[0035] During implementation, a lock hole is provided on the ground below the door 100, and the position of the lock hole corresponds to the position of the first through hole when the door 100 is closed.

[0036] During implementation, spring 342 is in a compressed state when locking lever 341 is extended or retracted. The compressed state allows the extended state to be reset by elastic force, and at the same time improves the stability of the retracted state, preventing it from easily wobbling.

[0037] In this embodiment, as Figures 2-5 As shown, it also includes a horizontal locking mechanism, which is installed inside the door body 100 and is connected to the cam 330 for locking the door body 100 on the side.

[0038] In this way, by setting up a horizontal locking mechanism, the door 100 can not only be locked from below by the vertical locking mechanism, but also be locked laterally from the side by the horizontal locking mechanism. Both the vertical and horizontal locking mechanisms are driven by the cam 330, and one power structure realizes two actions. The structure is ingenious and simple, easy to implement, and has a low manufacturing cost.

[0039] In this embodiment, as Figures 2-5 As shown, the horizontal locking mechanism includes a rack 410 and a positioning assembly. The rack 410 is horizontally disposed inside the door body 100 and located above the cam 330. The transmission teeth on the rack 410 are connected to the worm gear structure on the cam 330. A rod frame 420 is horizontally fixed inside the door body 100. The rack 410 is horizontally slidably disposed on the rod frame 420. The rack 410 has a locking end 411. The positioning assembly is installed on the wall outside the door body 100. The locking end 411 can slide into the positioning assembly and lock with the positioning assembly.

[0040] In this way, the horizontal locking mechanism is formed by the rack 410 and the positioning component, which enables the cam 330 to move the rack 410 and lock the rack 410 with the positioning component. No other power source is needed, the power structure is relatively simple and the structure is relatively stable.

[0041] In practice, the rack 410 is provided with a sliding groove, and the rack 410 is slidably mounted on the frame 420 through the sliding groove.

[0042] In this embodiment, as Figures 2-5As shown, the positioning assembly includes a positioning base 431 and a magnet 432. The positioning base 431 is fixedly installed on the wall outside the door 100 and corresponds to the position of the locking end 411. A slot is provided in the positioning base 431, and the magnet 432 is installed in the bottom of the slot. An electromagnetic coil 433 is provided in the locking end 411. A second through hole is provided on the side of the door 100, and the position of the second through hole corresponds to the locking end 411. The locking end 411 can extend into the slot through the second through hole so that the electromagnetic coil 433 can magnetically attract and position the magnet 432.

[0043] In this way, by using the positioning seat 431, the magnet 432, and the electromagnetic coil 433 set in the locking end 411, the toothed bar 410 can achieve magnetic attraction between the electromagnetic coil 433 and the magnet 432 after it is inserted into the slot, thereby locking the door 100 laterally. The locking structure is relatively simple and has high stability.

[0044] In this embodiment, as Figures 2-5 As shown, it also includes a displacement mechanism, which is installed on the top of the door body 100 and is used to drive the door body 100 to move laterally.

[0045] In this way, the displacement mechanism allows the door 100 to move open and close under its drive. Since the door 100 is generally a lead door, which is heavy, the displacement mechanism can provide stable support for the door 100, making it easier for the door 100 to open and close.

[0046] In this embodiment, as Figures 2-5 As shown, the displacement mechanism includes a transmission housing 510, a second motor 520, and a lead screw 530. The transmission housing 510 has a transmission cavity. The second motor 520 is installed in the transmission housing 510. The lead screw 530 is installed in the transmission cavity and is connected to the second motor 520 in a transmission connection. The top of the door body 100 is provided with a transmission threaded channel 540, which is connected to the lead screw 530 in a transmission connection.

[0047] In this way, the displacement transmission of the door 100 is more stable and the transmission structure is more reliable through the transmission box 510, the second motor 520 and the lead screw 530.

[0048] During implementation, the lead screw 530 and the rotating shaft of the second motor 520 are connected coaxially.

[0049] During implementation, the transmission threaded passage 540 is connected to the lead screw 530 via threaded transmission.

[0050] In this embodiment, as Figures 2-5As shown, it also includes a limit switch 610 and a trigger rod 620. The limit switch 610 is installed on the side wall of the door body 100 and is used to control the locking state of the vertical locking mechanism. The trigger rod 620 is installed on the side wall of the transmission cavity. When the door body 100 is closed, the trigger rod 620 can trigger the limit switch 610.

[0051] In practice, the limit switch 610 is electrically connected to the microprocessor 220, and the microprocessor 220 is electrically connected to the first motor 310. When the limit switch 610 is triggered, it can transmit an electrical signal to the microprocessor 220. The microprocessor 220 can send a control signal to the first motor 310 to control the rotation distance and rotation direction of the first motor 310.

[0052] In this way, by using the limit switch 610 and the trigger rod 620, the door 100 can automatically control the locking state of the vertical locking mechanism when closing and opening. The control process is relatively simple and the triggering structure is stable and reliable.

[0053] In this embodiment, as Figures 2-5 As shown, the X-ray monitoring module also includes an ADC module 230 and a buzzer 240. Both the ADC module 230 and the buzzer 240 are installed inside the door 100. The X-ray sensor 210 and the microprocessor 220 are electrically connected to the ADC module 230, and the buzzer 240 is electrically connected to the microprocessor 220.

[0054] In implementation, the X-ray sensor 210 is electrically connected to the ADC module 230 to collect X-ray radiation intensity information; the ADC module 230 is electrically connected to the microprocessor 220 to convert the X-ray radiation information collected by the X-ray sensor 210 from an analog signal to a digital signal, and sends the converted digital signal containing X-ray radiation intensity information to the microprocessor 220; the microprocessor 220 is electrically connected to the ADC module 230 and the buzzer 240 to process the digital signal containing X-ray radiation intensity information sent by the ADC module 230, and sends a command to the buzzer 240 according to the processing result; the buzzer 240 is electrically connected to the microprocessor 220, and emits an audible alarm after receiving the alarm command issued by the microprocessor 220.

[0055] During implementation, an indicator light is installed on the outside of the door to indicate whether the radiation work in the radiation room has been terminated. The indicator light is electrically connected to the microprocessor 220, and the buzzer 240 can respond synchronously with the indicator light.

[0056] In this way, through the configured ADC module 230 and buzzer 240, the X-ray sensor 210 can perform analog-to-digital conversion through the ADC module 230, while the buzzer 240 can announce after detecting that the X-ray radiation information has decreased to a safe level.

[0057] The above are merely preferred embodiments of the present invention. It should be noted that any modifications and improvements made by those skilled in the art without departing from the present technical solution should also be considered to fall within the scope of protection claimed in this claim.
