Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a high-efficiency cleaning and disinfection device for medical devices. Background Technology

[0002] In the medical field, the cleaning and disinfection of medical devices are key steps to ensure medical safety and quality. If cleaning is not thorough, residual dirt and pathogens can easily lead to cross-infection, and if disinfection is inadequate, the growth and spread of germs can cause serious medical accidents.

[0003] Traditional cleaning and disinfection methods, such as soaking or high-temperature steam, can remove dirt and bacteria from the surface of medical devices to some extent, but they have obvious limitations. Especially for medical devices with complex structures and small gaps and grooves on the surface, these methods often fail to achieve a thorough cleaning effect. Soaking cannot effectively penetrate into the gaps and grooves, resulting in dirt residue. While high-temperature steam cleaning has a good sterilization effect, the penetration power of steam is limited, making it difficult to evenly act on every detail of the medical device.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 6This utility model provides an embodiment: a high-efficiency cleaning and disinfection device for medical devices, including a disinfection cabinet 1 with a built-in partition and a cabinet door 2 located at the front end of the disinfection cabinet 1, a rotating module located on the lower side of the partition and an ultrasonic module located on the upper side of the partition. A hydraulic cylinder 3 is located on the top of the disinfection cabinet 1, and a disinfection basket 4 for placing medical devices is located at the power output end of the hydraulic cylinder 3. The four walls of the disinfection basket 4 are provided with water permeable holes 5. The rotating module includes a first bearing seat 6 located at the bottom of the disinfection cabinet 1, a support shaft 7 rotatably connected inside the first bearing seat 6, a turntable 8 located at the upper end of the support shaft 7, a power unit located on the lower side of the partition, and the support shaft 7 is driven to rotate by the power unit. A water tank 9 for storing disinfectant solution is located at the upper end of the turntable 8 via a clamping unit. The ultrasonic module includes an ultrasonic generator 10 located on the partition and a vibrator 11 electrically connected to the ultrasonic generator 10. A bracket 12 is located at the upper end of the partition, and the bracket 12 is connected to the vibrator 11 via a fixing unit. The vibrator 11 is located in the water tank 9. A hydraulic cylinder 3 is located on the top of the disinfection cabinet 1. The built-in power supply of the ultraviolet lamp 13 and the disinfection cabinet 1 serve as the main structure of the entire device, providing a closed and independent space environment for the cleaning and disinfection of medical devices, effectively preventing external contamination. The No. 1 bearing seat 6 serves as the mounting base for the support shaft 7, providing stable support for the support shaft 7 while allowing the support shaft 7 to rotate freely inside. The support shaft 7 rotates under the drive of the power unit, thereby driving the turntable 8 to rotate as well. The turntable 8 fixes the water tank 9 storing disinfectant through the clamping unit. Driven by the support shaft 7, the turntable 8 can drive the water tank 9 to rotate synchronously, causing the disinfectant in the water tank 9 to form a vortex, enhancing the rinsing effect on medical devices and improving the uniformity and efficiency of cleaning and disinfection. The ultrasonic generator 10 is set on the partition and is used to convert electrical energy into high-frequency electrical signals and transmit these electrical signals to the vibrator 11, providing the energy required for the operation of the vibrator 11. When the high-frequency electrical signals generated by the ultrasonic generator 10 are transmitted to the vibrator 11, the vibrator 11 will vibrate at high frequency, thereby generating a large number of tiny bubbles in the disinfectant.These bubbles grow and contract continuously under the action of ultrasound, eventually bursting to generate powerful impact force and high temperature and pressure, which peels off and kills dirt and bacteria on the surface of medical devices, achieving efficient and deep cleaning and disinfection. The fixing unit is used to firmly fix the vibrator 11 to the bracket 12 to prevent the vibrator 11 from loosening or falling off during vibration, ensuring the normal operation of the ultrasound module. The hydraulic cylinder 3, as the power actuator, has its power output end connected to the disinfection basket 4 where the medical devices are placed, driving the disinfection basket 4 to move up and down. During the cleaning and disinfection process, by controlling the action of the hydraulic cylinder 3, the disinfection basket 4 can be immersed... The disinfectant solution enters or leaves the water tank 9 to perform operations such as soaking, cleaning, and draining disinfection of medical devices. The disinfection basket 4 is used to place the medical devices to be cleaned and disinfected. It has water-permeable holes 5 on its four walls. The design of the water-permeable holes 5 allows the disinfectant solution to freely enter and exit the disinfection basket 4, ensuring that the medical devices can fully contact the disinfectant solution during the cleaning and disinfection process, thereby improving the cleaning and disinfection effect. The ultraviolet lamp 13 emits ultraviolet light when it is working. Ultraviolet light has a strong bactericidal ability and can irradiate the surface of the medical devices to kill residual bacteria, viruses and other microorganisms, further ensuring the cleaning and disinfection effect of the medical devices and achieving a higher hygiene standard.

[0023] Please see Figure 3 - Figure 4 In this embodiment, the power unit includes a second bearing seat 14 disposed on the side wall of the disinfection cabinet 1, a servo motor 15 disposed at the bottom of the disinfection cabinet 1, a worm gear 16 rotatably connected inside the second bearing seat 14, one end of the worm gear 16 being connected to the output shaft of the servo motor 15, a worm wheel 17 disposed on the outer wall of the support shaft 7, and the worm gear 16 meshing with the worm wheel 17. The clamping unit includes a support plate 18 disposed on the turntable 8, a screw 19 threadedly connected inside the support plate 18, a first knob 20 disposed at one end of the screw 19, and a clamping block 21 disposed at the other end of the thread. The second bearing seat 14 provides a stable and reliable mounting and rotation support foundation for the worm gear 16. The servo motor 15, as the core power source of the power unit, provides stable and reliable power for the rotation of the worm gear 16. With adjustable power, the worm gear 16 rotates under the drive of the servo motor 15, transmitting the rotational power output by the servo motor 15 to the worm wheel 17. This ensures that the support shaft 7 can drive the turntable 8 and the water tank 9 to rotate at a suitable speed and torque, completing the rotational cleaning and disinfection operation of the medical device. The support plate 18 provides a support platform for the installation and rotation of the screw 19. By rotating the first knob 20, the screw 19 can be driven to rotate within the support plate 18. Due to the self-locking characteristic of the threaded connection between the screw 19 and the support plate 18, the screw 19 can move along the axial direction, thereby pushing the clamping block 21 closer to or away from the water tank 9, realizing the clamping or releasing operation of the water tank 9, ensuring that the water tank 9 remains stable during rotation and does not shake or shift.

[0024] Please see Figure 1 and Figure 6 In this embodiment, the fixing unit includes a fixing plate 22 mounted on the upper end of the bracket 12. A bidirectional lead screw 23 is rotatably connected inside the fixing plate 22. A second knob 24 is provided at one end of the bidirectional lead screw 23. A movable plate 25 is threadedly connected to the outer wall of the bidirectional lead screw 23. A clamping plate 26 with an internal slot 27 is provided on the movable plate 25. Rubber sheets with anti-slip textures are provided on the surfaces of the first knob 20 and the second knob 24. A sliding rod 28 is provided between two adjacent fixing plates 22. The outer wall of the sliding rod 28 is slidably connected to the movable plate 25. An observation window 29 is provided on the surface of the cabinet door 2. A sealing strip is provided in the gap between the observation window 29 and the cabinet door 2. The fixing plate 22 provides an installation base for the bidirectional lead screw 23 and the sliding rod 28. By rotating the second knob 24, the bidirectional lead screw 23 can be driven within the fixing plate 22. The special thread design of the bidirectional lead screw 23 allows the two moving plates 25 connected by its outer wall thread to move simultaneously in opposite directions, thereby adjusting the distance between the clamping plates 26 to accommodate the installation requirements of vibrators 11 of different sizes and ensuring that the vibrators 11 can be firmly fixed on the bracket 12. The sliding rod 28 provides guidance for the movement of the moving plates 25, ensuring that the moving plates 25 can move smoothly along a straight line under the drive of the bidirectional lead screw 23, preventing the moving plates 25 from shifting or shaking during movement. The observation window 29 allows operators to directly observe the cleaning and disinfection process of medical devices inside the disinfection cabinet 1 without opening the cabinet door 2. The sealing strip is used to seal gaps to prevent external dust, bacteria and other pollutants from entering the disinfection cabinet 1, ensuring the cleanliness of the internal environment of the disinfection cabinet 1.

[0025] Working principle: First, place the medical devices to be cleaned and disinfected in the disinfection basket 4. Then, close the cabinet door 2 of the disinfection cabinet 1 and start the hydraulic cylinder 3 to drive the disinfection basket 4 to immerse in the disinfectant solution in the water tank 9, thereby immersing the medical devices.

[0026] Next, the servo motor 15 drives the worm gear 16 to rotate in the bearing housing 14. The worm gear 16 meshes with the worm wheel 17 on the outer wall of the support shaft 7, transmitting the rotational power to the support shaft 7. The support shaft 7 drives the turntable 8 to rotate, and the water tank 9 fixed by the clamping unit also rotates synchronously. The disinfectant in the water tank 9 forms a vortex under the action of rotation, which enhances the rinsing effect on medical devices and improves the uniformity and efficiency of cleaning and disinfection.

[0027] At the same time, the ultrasonic module is activated, and the ultrasonic generator 10 converts electrical energy into high-frequency electrical signals, which are transmitted to the vibrator 11 located in the water tank 9. Under the action of the high-frequency electrical signals, the vibrator 11 vibrates at high frequency, generating a large number of tiny bubbles in the disinfectant. These bubbles grow and contract under the action of ultrasonic waves, and eventually burst, generating a powerful impact force and high temperature and pressure to peel off and kill dirt and bacteria on the surface of medical devices, achieving efficient and deep cleaning and disinfection.

[0028] Finally, the hydraulic cylinder 3 is activated to remove the disinfection basket 4 from the disinfectant solution in the water tank 9, allowing the medical devices to drain. At the same time, the ultraviolet lamp 13 emits ultraviolet light to disinfect the medical devices. After cleaning and disinfection are completed, the device is turned off, the cabinet door 2 is opened, and the medical devices in the disinfection basket 4 are taken out.

[0029] Through the above steps, combining the advantages of rotary rinsing and ultrasonic cleaning, the disinfectant solution forms a vortex, enhancing the rinsing force and uniformity, and improving cleaning efficiency. The high-frequency vibration of the transducer 11 generates microbubbles, which burst and peel off to kill dirt and bacteria, achieving deep cleaning and disinfection. The addition of an ultraviolet lamp 13 further kills residual microorganisms, ensuring the cleaning and disinfection effect. This solves the problem that traditional cleaning and disinfection methods are difficult to thoroughly clean medical devices with complex structures and small gaps and grooves on the surface.
