Description

Technical Field

[0001] This invention relates to the field of medical disinfection and sterilization technology, specifically to an intelligent medical disinfection and sterilization device for use in operating room environments. Background Technology

[0002] As the core location for surgical treatment and invasive procedures in medical institutions, the operating room is a key risk factor for surgical site infection due to environmental microbial contamination, which is directly related to the patient's treatment safety and postoperative recovery.

[0003] Existing disinfection devices mostly use fixed-angle or single-direction spraying nozzles, making it difficult to achieve full coverage of the three-dimensional space such as operating room walls, ceilings, and equipment surfaces, resulting in blind spots in environmental disinfection. At the same time, for the operating bed area, there is a lack of a moving spray structure that can automatically move and uniformly cover the bed surface and bed frame gaps, resulting in incomplete bed disinfection and easy retention of microorganisms. In addition, disinfection nozzles are usually fixed by complex methods such as bolts or clamps, which are time-consuming to disassemble and replace, and inconvenient to operate, affecting the efficiency of continuous disinfection operations and the convenience of maintenance. Based on this, the present invention designs an intelligent medical disinfection and sterilization device for operating room environments to solve the above problems. Summary of the Invention

[0020] 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.

[0021] Example 1 Please see Figures 1-4 An intelligent medical disinfection and sterilization device for operating room environments includes: a mobile box 1, with casters 2 inside the mobile box 1 and a telescopic mechanism inside the mobile box 1 for extending and retracting the casters 2; an adjustment mechanism located on top of the mobile box 1 for adjusting direction and height; and a working mechanism located on top of the adjustment mechanism for disinfecting and sterilizing the operating room environment. The working mechanism includes a tilting component and a moving component. The tilting component is located on top of the adjustment mechanism for disinfecting the operating room environment, and the moving component is located on top of the adjustment mechanism for disinfecting the bed in the operating room environment.

[0022] The telescopic mechanism includes a dual-axis motor 3 mounted on one side of the movable box 1. A bidirectional lead screw 4 is mounted on one side of the output shaft of the dual-axis motor 3. The dual-axis motor 3 and the bidirectional lead screw 4 are connected by a coupling. The outer ring of the bidirectional lead screw 4 is threaded with a sliding block 5. Two sets of sliding blocks 5 are arranged symmetrically. A linkage assembly is provided at the bottom of the sliding block 5. The linkage assembly includes a limiting block 6 installed in the inner cavity of the movable box 1. A first linkage plate 7 is hinged to the bottom of the sliding block 5. A second linkage plate 8 is hinged to the inner cavity of the limiting block 6. The first linkage plate 7 and the second linkage plate 8 are rotatably connected by a hinge. A caster wheel 2 is installed at the bottom of the hinge.

[0023] The working principle of this invention is as follows: the dual-axis motor 3 drives one output shaft to rotate the bidirectional lead screw 4. Two sets of symmetrically distributed variable blocks 5 move in opposite directions or in a straight line along the bidirectional lead screw 4, which drives the first linkage plate 7 hinged at the bottom to move synchronously. The first linkage plate 7 and the second linkage plate 8 hinged to the limit block 6 form a linkage folding structure through a hinge. The universal wheel 2 at the bottom of the hinge extends to support or retracts to hide as the linkage plate opens and closes. When extended, the universal wheel 2 lands on the ground to support the movable box 1, ensuring that the device can be flexibly transferred to the disinfection point.

[0024] Example 2 Please see Figures 1-5 In this embodiment of the invention, the adjustment mechanism includes a rotating frame 9 mounted on the top of the movable box 1. A connecting rod 10 is installed inside the rotating frame 9. A rotating rod 11 is installed on the other side of the output shaft of the dual-axis motor 3. Tensioning wheels 12 are installed on one side of both the connecting rod 10 and the rotating rod 11. The tensioning wheels 12 are connected by a belt 13. A driving bevel gear 14 is installed on one side of the connecting rod 10. A driven rod 15 is installed inside the rotating frame 9. A driven bevel gear 16 is installed on the outer ring of the driven rod 15. The driving bevel gear 14 and the driven bevel gear 16 mesh with each other. A rotating plate 17 is installed on the top of the driven rod 15. A sliding assembly is installed between the rotating frame 9 and the rotating plate 17. A lifting assembly is installed on the top of the rotating plate 17.

[0025] The sliding assembly includes a groove 18 formed on the top of the rotating frame 9, with a ball 19 slidably connected inside the groove 18. A fixing rod 20 is mounted on the top of the ball 19. Multiple sets of balls 19 and fixing rods 20 are arranged in a circumferential array. The lifting assembly includes a first hydraulic telescopic rod 21 mounted on the top of the rotating plate 17, with a lifting plate 22 mounted on the top of the first hydraulic telescopic rod 21. Limiting telescopic rods 39 are installed between the lifting plate 22 and the rotating plate 17. Four sets of limiting telescopic rods 39 are arranged in a rectangular array.

[0026] The working principle of this invention is as follows: When the adjustment mechanism is activated, the output shaft on the other side of the dual-axis motor 3 drives the rotating rod 11 to rotate. Through the transmission of the tension wheel 12 and the belt 13, the connecting rod 10 is driven to rotate synchronously. The active bevel gear 14 on the connecting rod 10 meshes with the driven bevel gear 16 on the passive rod 15, converting the horizontal rotational power into the vertical rotational power, which drives the rotating plate 17 to rotate smoothly. The rotating plate 17 and the rotating frame 9 are supported by a sliding assembly composed of groove 18, ball 19 and fixed rod 20. Multiple sets of circumferentially distributed ball 19 reduce rotational friction, ensuring that the rotating plate 17 drives the upper structure to rotate 360° without jamming, realizing full-range adjustment of the disinfection direction.

[0027] Example 3 Please see Figures 1-7 In this embodiment of the invention, the tilting component includes a support frame 23 installed on the top of the lifting plate 22. A first spraying connector 24 is hinged inside the support frame 23. A first disinfection nozzle 25 is installed on one side of the first spraying connector 24. A second hydraulic telescopic rod 26 is installed inside the support frame 23. The second hydraulic telescopic rod 26 is hinged to the first spraying connector 24 via a hinge.

[0028] The moving assembly includes a moving frame 27 mounted on the top of the lifting plate 22. A servo motor 28 is mounted on one side of the moving frame 27. A one-way lead screw 29 is mounted on one side of the output shaft of the servo motor 28. A moving block 30 is threadedly connected to the outer ring of the one-way lead screw 29. A second spraying connector 31 is mounted on the top of the moving block 30. A second disinfection nozzle 32 is mounted on the bottom of the second spraying connector 31. Both sides of the first disinfection nozzle 25 and the second disinfection nozzle 32 are provided with slots. A locking block 33 is slidably connected inside the slots. A pressing plate 34 is mounted on one side of the locking block 33. A guide telescopic rod 35 is mounted on one side of the pressing plate 34. A fixing plate 36 is mounted on one side of the guide telescopic rod 35. The fixing plate 36 is connected to the first spraying connector 24 and the second spraying connector 31 respectively. A compression spring 37 is installed between the fixing plate 36 and the pressing plate 34. The compression spring 37 is fitted onto the outer ring of the guide telescopic rod 35. A limit component is installed inside the moving frame 27. The limiting component includes a limiting guide rod 38 installed inside the movable frame 27. Two sets of limiting guide rods 38 are provided and are symmetrically distributed. The limiting guide rods 38 are inserted inside the movable block 30.

[0029] The working principle of this invention embodiment is as follows: In the tilting component, the second hydraulic telescopic rod 26 extends and retracts to push the first spraying connecting seat 24 to tilt up and down around the hinge point of the support frame 23, thereby driving the first disinfection nozzle 25 to swing and spray at multiple angles, covering the three-dimensional space such as the operating room walls, ceiling, and equipment surfaces, and completing the disinfection of the entire environment.

[0030] In the moving component, the servo motor 28 drives the one-way lead screw 29 to rotate. Under the limiting constraints of the two sets of limiting guide rods 38, the moving block 30 moves linearly back and forth along the one-way lead screw 29, driving the second spraying connection seat 31 and the second disinfection nozzle 32 to move synchronously and uniformly cover the operating table surface, bed frame gaps and other bed areas with spray disinfection.

[0031] Working Principle: After the device moves to the designated operating room location, the telescopic mechanism operates first. The dual-axis motor 3 drives one output shaft to rotate the bidirectional lead screw 4. Two sets of symmetrically distributed moving blocks 5 move in opposite directions along the bidirectional lead screw 4, causing the first linkage plate 7, which is hinged at the bottom, to move synchronously. The second linkage plate 8, which is hinged to the first linkage plate 7 and the limiting block 6, forms a linkage folding structure through a hinge. The universal wheels 2 at the bottom of the hinge extend to support or retract and hide as the linkage plates open and close. When extended, the universal wheels 2 support the moving box 1, ensuring that the device can be flexibly transferred to the disinfection point. When retracted, the universal wheels 2 retract into the inner cavity of the moving box 1, allowing the box to land stably and be fixed, preventing displacement during disinfection and providing a stable base for subsequent disinfection operations.

[0032] After the telescopic mechanism is positioned and fixed, the adjustment mechanism starts synchronously. The output shaft on the other side of the dual-axis motor 3 drives the rotating rod 11 to rotate. Through the transmission of the tension wheel 12 and the belt 13, the connecting rod 10 is driven to rotate synchronously. The active bevel gear 14 on the connecting rod 10 meshes with the driven bevel gear 16 on the passive rod 15, converting the horizontal rotational power into vertical rotational power, driving the rotating plate 17 to rotate smoothly. The rotating plate 17 and the rotating frame 9 are supported by a sliding assembly composed of grooves 18, balls 19 and fixed rods 20. Multiple sets of circumferentially distributed balls 19 reduce rotational friction, ensuring that the rotating plate 17 drives the upper structure to rotate 360° without jamming, realizing full-range adjustment of the disinfection direction. The first hydraulic telescopic rod 21 at the top of the rotating plate 17 extends and retracts, driving the lifting plate 22 to rise and fall vertically. Four sets of rectangularly distributed limiting telescopic rods 39 extend and retract synchronously to limit the movement of the lifting plate 22, preventing it from shifting or swaying, and precisely adjusting the height of the disinfection operation to adapt to different space heights and equipment layouts in the operating room.

[0033] After the height and direction are adjusted, the tilting and moving components of the working mechanism perform environmental and bed disinfection respectively. In the tilting component, the second hydraulic telescopic rod 26 extends and retracts, pushing the first spraying connecting seat 24 to tilt up and down around the hinge point of the support frame 23, causing the first disinfection nozzle 25 to swing and spray at multiple angles, covering the three-dimensional space such as the operating room walls, ceiling, and equipment surfaces, completing the full-area environmental disinfection. In the moving component, the servo motor 28 drives the one-way lead screw 29 to rotate, and the moving block 30 moves linearly back and forth along the one-way lead screw 29 under the limiting constraints of the two sets of limiting guide rods 38, causing the second spraying connecting seat 31 and the second disinfection nozzle 32 to move synchronously, uniformly and fully covering the operating table surface, bed frame gaps, and other bed areas with spray disinfection. The first disinfection nozzle 25 and the second disinfection nozzle 32 are fixed by a quick-installation structure consisting of a slot, a locking block 33, a squeezing plate 34, a guide telescopic rod 35, and a squeezing spring 37. The squeezing spring 37 provides clamping force to ensure that the nozzles are installed firmly and can be quickly disassembled and replaced, ensuring the continuous and efficient operation of disinfection work.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
