Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, specifically a rapid disinfection device for a magnetic resonance imaging (MRI) examination bed. Background Technology

[0002] The MRI examination table, a crucial component of magnetic resonance imaging (MRI) equipment, is the device where patients lie directly during the examination. With its precise movement and positioning capabilities, the examination table accurately guides the patient to the MRI scanning area, helping doctors obtain high-quality images. Due to the frequent use of MRI examinations, with numerous patients seen daily, pathogens such as bacteria and viruses carried by different patients can easily remain on the examination table. If not disinfected promptly, subsequent patients may experience cross-infection upon contact, impacting their health.

[0003] Utility model patent CN202021275883.4 discloses a cleaning and disinfection device for a magnetic resonance imaging (MRI) examination bed. This device includes a base and a support frame, with the support frame fixed above the base. The base, support frame, and frame are all made of magnetically compatible materials. The upper half of the frame houses a motor that has been modified to be non-magnetic. The lower half of the frame contains a debris box with a flexible tube for absorbing debris attached to its side; the free end of the tube is fixed to the side of the support frame. An ultraviolet (UV) lamp is slidably mounted on the other side of the support frame. A control button is located above the motor, allowing control of both the motor and the UV lamp. This magnetically compatible design allows for safe entry and exit from the MRI examination room, thoroughly cleaning hard-to-reach hair and fine sand from the bed. It also disinfects the bed. The height can be manually adjusted according to different types of MRI examination beds, effectively irradiating the bed surface. When the UV lamp is working, a warning light remains on, reminding personnel entering the room to take precautions.

[0004] Although the cleaning and disinfection device for this MRI examination table facilitates disinfection, it still presents the following problems in practical use: The device primarily relies on ultraviolet (UV) lamps for disinfection. However, UV lamps have significant limitations in practical application. Conventional MRI examination tables are generally around 2 meters long. Due to the limitations of the UV lamp's installation height and irradiation angle, its effective irradiation range is narrow, failing to fully cover the table surface. Furthermore, the disinfection effect of relying solely on UV lamps is limited, making it difficult to achieve comprehensive and effective disinfection of the table surface and increasing the risk of cross-infection.

[0005] In view of this, we propose a rapid disinfection device for magnetic resonance imaging (MRI) examination tables. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment provides a technical solution: Please see Figures 1-5 As shown, a rapid disinfection device for a magnetic resonance imaging examination bed includes a water tank 1 for storing disinfectant. A water pump 10 is installed at the bottom of the water tank 1. A drain pipe 11 is installed at the outlet of the water pump 10. The end of the drain pipe 11 away from the water pump 10 extends through the side wall of the water tank 1 to the outside and is fixed with a water delivery pipe 12.

[0021] An adjustment assembly for height and angle adjustment is installed on the top front side of the water tank 1. The adjustment assembly includes a bracket 2, the bottom of which is installed on the top front side of the water tank 1. A slide groove 20 is opened on the front side of the bracket 2. A lead screw 21 is rotatably installed in the slide groove 20. A motor 23 for driving the lead screw 21 to rotate is installed on the top of the bracket 2. The output shaft of the motor 23 is connected to the top of the lead screw 21. A connecting block 22 is threaded to the outside of the lead screw 21. The connecting block 22 is set in the slide groove 20 for limiting and sliding connection. The front end of the connecting block 22 extends to the outside of the slide groove 20 and is fixed to a connecting frame 24. An electric cylinder 26 is installed on the top of the connecting frame 24. A toothed block 27 is fixed at the end of the piston rod of the electric cylinder 26. The toothed block 27 slides through the inside of the connecting frame 24.

[0022] The front side of the adjustment component is provided with a spray disinfection component 3, which includes a hollow tube body 30. Multiple nozzles 31 for spraying disinfectant onto the magnetic resonance examination bed are installed at the bottom of the tube body 30. A connection port 32 is fixed at the rear end of the bottom of the tube body 30, and the top of the water supply pipe 12 is connected to the connection port 32. A connecting seat 33 is fixed at the rear end of the tube body 30. A half gear 34 is fixed at the rear end of the connecting seat 33. A connecting shaft 340 is coaxially fixed at the center of the half gear 34. The half gear 34 is located inside the connecting frame 24, and the two ends of the connecting shaft 340 pass through the two side walls of the connecting frame 24 and are rotatably connected to the connecting frame 24. The half gear 34 meshes with the tooth block 27.

[0023] An ultraviolet disinfection component 4 is provided above the tube body 30. The ultraviolet disinfection component 4 includes a plate 40 rotatably installed on the top of the tube body 30. Two mounting slots 400 are opened at the bottom of the plate 40. Two disinfection lamps 41 for irradiating the magnetic resonance examination table for disinfection are installed in each mounting slot 400.

[0024] In this embodiment, the slide 20 has a rectangular cross-sectional shape, and its dimensions are adapted to the dimensions of the connecting block 22. The rectangular cross-section of the slide 20 and the dimensions of the connecting block 22 are adapted to each other, which can effectively prevent the connecting block 22 from shaking or shifting during the lifting process, and ensure the stability and accuracy of the adjustment component operation.

[0025] In this embodiment, a threaded post 35 is fixed at the top center of the tube body 30, and a nut 36 is threaded onto the threaded post 35; a shaft hole 401 for the threaded post 35 to pass through is provided at the top center of the plate body 40, and the bottom surface of the nut 36 can abut against the top of the plate body 40. This design not only facilitates the rotation of the plate body 40, but also flexibly fixes the position of the plate body 40, improving the ease of use of the ultraviolet disinfection component 4 and meeting the disinfection and storage needs of the ultraviolet disinfection component 4.

[0026] In this embodiment, the connecting seat 33 and the half gear 34 are integrally formed, and the tooth grooves on the half gear 34 are formed by gear hobbing. The integral forming process enhances the structural strength between the connecting seat 33 and the half gear 34, while the gear hobbing process ensures the precision of the half gear 34, thereby ensuring the stability of the meshing between the half gear 34 and the tooth block 27 and extending the service life of the equipment. In this embodiment, casters 13 are installed at the four corners of the bottom of the water tank 1, and two inclined support rods 14 are fixed to the rear top of the water tank 1, with a handle 15 fixed between the tops of the two support rods 14.

[0027] In this embodiment, the bracket 2 has a U-shaped cross-section, and the bottom of the bracket 2 is fixedly connected to the water tank 1 by bolts. The U-shaped design has better structural strength, and the bolt fixing method not only ensures the reliable installation of the bracket 2, but also has the advantage of easy assembly and disassembly.

[0028] In this embodiment, a filling port is installed at the rear top of the water tank 1, and a plug is installed at the filling port. This design facilitates the addition of disinfectant to the water tank 1, and the plug effectively prevents disinfectant leakage and evaporation, ensuring the normal operation and safe use of the equipment.

[0029] It is understood that in this embodiment, the multiple nozzles 31 are linearly and equally spaced at the bottom of the tube body 30. This design ensures that the disinfectant is sprayed evenly on the surface of the examination bed, avoids situations where there is too much or too little disinfectant in some areas, and ensures the consistency and comprehensiveness of disinfection.

[0030] It should be added that the outer wall of the water tank 1 in this embodiment is provided with a transparent observation window. The transparent observation window allows the staff to intuitively see the remaining amount of disinfectant in the water tank 1, so as to facilitate timely replenishment of disinfectant and ensure that the disinfection work can continue.

[0031] Furthermore, the water supply pipe 12 in this embodiment is a corrugated pipe, which has flexibility and extensibility. This design allows the water supply pipe 12 to not only meet the needs of conveying disinfectant, but also meet the needs of height and angle adjustment of the spray disinfection component 3. Moreover, the disinfectant sprayed from the nozzle 31 is in the form of a mist, avoiding excessive disinfectant residue on the magnetic resonance examination bed that would cause it to flow everywhere.

[0032] It is worth noting that the water pump 10 and motor 23 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0033] Before use, the user first turns on the power to the motor 23. The motor 23 starts working, and the output shaft of the motor 23 rotates, driving the lead screw 21 to rotate. Since the lead screw 21 is threadedly connected to the connecting block 22, the connecting block 22 moves vertically and drives the connecting frame 24 and the pipe body 30 to move vertically. When the pipe body 30 drives the nozzle 31 to the required height, the user turns off the power to the motor 23. Then the user loosens the nut 36 and rotates the plate 40. When the plate 40 rotates 90°, the user tightens the nut 36, and the plate 40 is fixed.

[0034] In practical use, the user first turns on the power to the water pump 10, and the water pump 10 starts working. At this time, the disinfectant enters the water supply pipe 12 through the drain pipe 11, and then enters the pipe body 30. At this time, the disinfectant is sprayed onto the top of the magnetic resonance examination table through multiple nozzles 31 for disinfection. At the same time, the user pushes the device along the magnetic resonance examination table, and the nozzles 31 can spray the disinfectant all over the top of the magnetic resonance examination table. Then the user turns on the power to the disinfection lamp tube 41, and the disinfection lamp tube 41 starts working and irradiates and disinfects the top of the magnetic resonance examination table.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
