Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to an ultraviolet disinfection device for magnetic resonance environments. Background Technology

[0002] In the field of modern medical diagnostics, magnetic resonance imaging (MRI) equipment has become indispensable due to its ability to provide high-resolution images of the internal structures of the human body, playing a particularly important role in the diagnosis of diseases of the nervous, musculoskeletal, and cardiovascular systems. However, the working environment of MRI equipment—the MRI shielded room—poses significant challenges to the normal operation of sterilization equipment and data transmission due to its unique high magnetic field environment. Existing sterilization equipment also has many shortcomings in terms of structure and function. Existing ultraviolet lamps in disinfection equipment are typically fixed in place, making it impossible to flexibly adjust the irradiation angle according to actual disinfection needs. This design results in blind spots in disinfection, failing to fully cover the disinfection area and affecting the disinfection effect.

[0003] Traditional wireless communication technologies (such as WIFI and Bluetooth) cannot work effectively in the magnetic resonance shielded room. The signals have difficulty penetrating the metal walls, resulting in most devices lacking real-time data acquisition capabilities or only being able to transmit data through the gaps in the shielded room door. This cannot meet the medical environment's need for full-process monitoring and precise management of disinfection operations. This information lag is not conducive to timely tracing of the disinfection process, making it difficult to effectively improve disinfection quality and efficiency, increasing the risk of infection, and posing a potential threat to medical safety.

This equipment can not only adjust the irradiation direction and range of the ultraviolet disinfection components according to actual disinfection needs, but also stably transmit the disinfection data of the equipment to an external base station. This effectively solves the problem that traditional communication technology cannot work effectively in environments with strong electromagnetic interference and shielding, and ensures real-time data acquisition and monitoring.

[0005] To solve the above-mentioned technical problems, this utility model provides an ultraviolet disinfection device for magnetic resonance environment, including a disinfection device comprising a counterweight chassis, a support shell, a protective cover, a top cover, and ultraviolet disinfection components.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0018] Reference Figure 1-3 As shown, this utility model discloses an ultraviolet disinfection device for magnetic resonance environment, comprising a disinfection device 1, which includes a counterweight base 11, a support shell 12, a protective cover 13, a top cover 14, and ultraviolet disinfection components 15. The support shell 12 is disposed on the counterweight base 11, and the top cover 14 is fastened to the top of the support shell 12. A main control board is disposed inside the support shell 12. The protective cover 13 is rotatably disposed on the top of the support shell 12, and two sets of ultraviolet disinfection components 15 are rotatably disposed on the inner wall of the protective cover 13, and the ultraviolet disinfection components 15 are electrically connected to the main control board. The LORA transmitter 2 is disposed on the top of the support housing 12. The LORA transmitter 2 is connected to the main control board via a connector and receives disinfection data sent by the main control board. Antenna 3, housed within the top cover 14, receives disinfection data transmitted by the LORA transmitting component 2 and forwards it to the LORA base station outside the magnetic resonance shielding room. Antenna 3 enhances the gain of the LORA transmitting component 2, effectively mitigating losses caused by the magnetic resonance shielding room. The LORA base station, located outside the magnetic resonance shielding room, receives disinfection data transmitted by the LORA transmitting component 2 and transmits it to the hospital's disinfection platform.

[0019] In practical applications, a LoRa base station can select a suitable location among multiple imaging devices so that the LoRa transmission components 2 of multiple disinfection devices 1 can connect and transmit data.

[0020] The main control board in this embodiment is existing technology. The main control board used is an STM32F103ZET6. This application does not improve the main control board.

[0021] In this embodiment, the LORA transmitting component 2 is also existing technology, and this application does not improve upon it. Preferably, the LORA transmitting component 2 is model USR-LG206-LC, with an operating frequency of 433MHz, a transmit power of 20dBm, an operating voltage of 5V, and a LORA base station receiving sensitivity of -130dBm. The LORA transmitting component 2 solves the problem in the prior art where the use of the disinfection device 1 is not recorded or the paper records are incomplete due to the obstruction of the shielding room. Real-time disinfection data can provide more comprehensive disinfection decisions and facilitate problem tracing. Through the antenna 3, the RSSI value of the disinfection data collected by the LORA transmitting component 2 after penetrating the magnetic resonance shielding room and received by the base station is around -100dBm, ensuring communication for disinfection data collection.

[0022] In this embodiment, the LORA transmitter component 2, model USR-LG206-LC, includes a serial communication module, a LORA module, and an MCU module. The serial communication module connects to the main control board of the disinfection device 1 and receives disinfection data. The LORA module is used for LORA communication, and the MCU module is used for centralized control. The disinfection data from the disinfection device 1 is sent to the serial communication module via the serial port. The MCU module packages the data and encapsulates a header, which includes an 8-bit transmitter component device code, a 2-bit checksum, and a 2-bit timecode. The LORA module then transmits the packaged data to the LORA base station outside the shielded room after amplification via antenna 3. The base station transmits the data to the platform via the network using the TCP / IP protocol.

[0023] In this embodiment, the hardware connection between the main control board and the LORA transmitter component 2 is as follows: Figure 7 As shown, the RX interface on the main control board is connected to the RXD interface on the LORA transmitter 2 to receive data from the LORA transmitter 2; the TX interface on the main control board is connected to the TXD interface on the LORA transmitter 2 to send data to the LORA transmitter 2; the DC5V interface on the main control board is connected to the VCC interface on the LORA transmitter 2 to provide 5V power to the LORA transmitter 2; and the GND interface on the main control board is connected to the GND interface on the LORA transmitter 2 to form a complete circuit loop. This connection method is achieved through the 2.54mm*1 7pin DIP connector interface, ensuring a stable connection and data transmission between the main control board and the LORA transmitter 2.

[0024] The LORA launcher 2 is only the size of a matchbox and can be installed in any suitable location on the disinfection device 1 without requiring the disinfection device 1 to change its structure and appearance design or install a separate launcher module.

[0025] like Figure 4 and 5 As shown, a folding angle adjustment seat 131 is provided on the top of the protective cover 13. The folding angle adjustment seat 131 is connected to the support housing 12 via a support shaft 132. The folding angle adjustment seat 131 is provided with multiple limiting slots 1311. The design of the folding angle adjustment seat 131 and the limiting slots 1311 allows the tilt angle of the protective cover 13 to be adjusted as needed, thereby changing the irradiation direction of the ultraviolet disinfection component 15, improving the flexibility and adaptability of disinfection. Users can precisely adjust the angle of the ultraviolet lamp 153 according to the actual disinfection scenario and target object to improve the disinfection effect.

[0026] Preferably, the support housing 12 is provided with a lamp tube recovery chamber, which is lined with an arc-shaped rubber pad to prevent the lamp tubes from colliding during transportation and handling; the top of the protective cover 13 has a slanted rubber strip. When the ultraviolet disinfection component 15 is recovered into the lamp tube recovery chamber along with the protective cover 13, the rubber strip overlaps with the lamp tube recovery chamber and tightens to prevent the ultraviolet disinfection component 15 inside from breaking due to external force impacting the protective cover 13 during transportation.

[0027] When the entire device needs to be moved, the protective cover 13 and the ultraviolet disinfection component 15 can be adjusted to retract the ultraviolet disinfection component 15 into the lamp recycling compartment inside the support housing 12 to avoid damage to the ultraviolet disinfection component 15.

[0028] In addition, the top cover 14 is equipped with a locking element, which cooperates with the folding angle adjustment seat 131 to lock the protective cover 13. The locking element can firmly lock the protective cover 13 at the adjusted angle, ensuring that the ultraviolet disinfection component 15 remains stable during the disinfection process and preventing the angle from changing due to external force.

[0029] Specifically, the locking component includes a locking block 141 and a locking pin 142. The locking block 141 is disposed inside the top cover 14 via a second support shaft 143. The locking pin 142 is disposed above the locking block 141 and is inserted into a slotted hole 140 in the top cover 14. When the locking pin 142 slides within the slotted hole 140, it causes the locking block 141 to rotate around the second support shaft 143, thereby enabling the locking block 141 to engage or disengage from the folding angle adjustment seat 131. The design of the locking block 141 and the locking pin 142 provides a precise locking and unlocking mechanism, is simple and convenient to operate, and can quickly adjust and fix the angle of the protective cover 13. like Figure 6 As shown, the ultraviolet disinfection assembly 15 includes a rotating connector 151, a lamp holder 152, and an ultraviolet lamp 153. The rotating connector 151 is rotatably connected to the protective cover 13. The lamp holder 152 is mounted on the rotating connector 151, and the ultraviolet lamp 153 is mounted on the lamp holder 152. The position and angle of the ultraviolet lamp 153 can be flexibly adjusted via the rotating connector 151, further improving the adaptability and flexibility of disinfection. Moreover, this adjustable design allows the equipment to be adapted to disinfection spaces of different sizes and shapes, enhancing the equipment's versatility.

[0030] Preferably, the rotating connector 151 is an adjusting gear, and the adjusting gears of the two sets of ultraviolet disinfection components 15 mesh. The meshing adjusting gear design enables the synchronous adjustment of the two sets of ultraviolet lamps 153, ensuring the uniformity and consistency of disinfection. The user only needs to operate one set of ultraviolet lamps 153, and the other set will be adjusted synchronously, reducing the difficulty of operation.

[0031] In this embodiment, a lamp tube limiting groove is provided inside the lamp tube holder 152. The lamp tube limiting groove ensures the lamp tube's stable position during the disinfection process, preventing displacement due to movement or vibration, and ensuring the accuracy and stability of ultraviolet irradiation. Two stainless steel wire rods are respectively provided on both sides of the lamp tube holder 152 to stabilize the ultraviolet lamp 153 and prevent it from falling off.

[0032] The protective cover 13 is equipped with a control handle 16, which is movably connected to the lamp holder 152 in one of the ultraviolet disinfection components 15 via a connecting rod assembly 19. The design of the control handle 16 and the connecting rod assembly 19 allows users to manually adjust the position and angle of the ultraviolet lamp 153, providing a convenient operating method.

[0033] In this embodiment, the linkage assembly 19 includes a first linkage and a second linkage, which are movably connected. The movably connected linkage assembly 19 enables multi-angle adjustment, further improving the flexibility and adaptability of the ultraviolet lamp 153.

[0034] like Figure 8 As shown, antenna 3 is a copper rod antenna. Copper rod antennas have good signal transmission performance and high transmission efficiency, which can ensure that disinfection data is stably transmitted to external base stations. In addition, copper rod antennas have a simple structure, strong corrosion resistance, and are suitable for long-term use in complex environments such as magnetic resonance shielding rooms.

[0035] In this embodiment, the counterweight chassis 11 is equipped with rollers 17 at its bottom. The counterweight chassis 11 is made of aluminum alloy, and a 10KG lead block is installed at the bottom of the counterweight chassis 11 to act as a counterweight, stabilizing the stability of the disinfection device 1 after it is unfolded and counteracting the weak magnetic attraction of the disinfection device 1 by magnetic resonance. The design of the rollers 17 facilitates the user's movement of the device in different positions, improving the portability and flexibility of the device. The user can easily push the device, reducing the labor intensity required to move the device. In this embodiment, there are four rollers 17, all of which are silent locking casters.

[0036] In addition, a push handle 18 is provided on the support housing 12. The push handle 18 provides a convenient grip position, allowing users to push the device more easily.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
