Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically a cleaning device for intensive care unit nursing. Background Technology

[0002] The patent application number CN202222632189.9 describes a cleaning device for intensive care unit nursing. Through the coordinated use of a servo motor, worm gear, worm wheel, slider, moving rod, and connecting rod, it can more conveniently and quickly push the cleaning mesh frame upward above the cleaning liquid surface, avoiding contamination and erosion of the staff's hands and skin, further facilitating the operation and use of the device, and improving safety during use.

[0003] The aforementioned patent, by introducing a cleaning frame, causes the medical devices on it to be flushed out of the cleaning solution. During this upward movement of the cleaning frame, dirt in the cleaning solution can easily re-adhere to the surface of the medical devices. Furthermore, even after the cleaning frame is removed, a significant amount of cleaning solution remains at the contact point between the device and the frame. If the user handles the device at this point, it will still be subject to contamination and corrosion. Additionally, placing the device inside the cleaning frame results in insufficient contact between the device and the cleaning solution during the cleaning process, thus compromising the cleaning quality. Based on this, the present invention designs a cleaning device for intensive care unit nursing to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning device for intensive care unit nursing, in order to solve the problems mentioned in the background art, such as easy re-contamination of dirt after cleaning, incomplete drainage of cleaning solution, and incomplete cleaning.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cleaning device for intensive care unit nursing includes a mounting frame and a mounting plate. The mounting plate is fixed above the mounting frame. A cleaning cylinder is rotatably mounted on the mounting frame. A driven gear is fixedly mounted on the upper end of the cleaning cylinder. Multiple control components are fixedly mounted on the cleaning cylinder. A movable partition is provided inside each control component, which longitudinally divides the cleaning cylinder into multiple sections. Threaded sleeves are rotatably mounted on both ends of the mounting plate. A threaded rod is threadedly connected to the threaded sleeve. A positioning ring is fixedly mounted on the lower end of the threaded rod. Multiple mounting rings are fixedly mounted on the lower surface of the positioning ring. A transmission structure is provided between the threaded sleeve and the driven gear. The transmission structure can drive the driven gear to reciprocate while simultaneously driving the threaded sleeve to rotate continuously.

[0007] Preferably, the transmission structure includes a connecting shaft and a fixed shaft. Two sets of connecting shafts are provided and rotatably connected to the mounting frame at diagonal positions. The connecting shafts are rotatably connected to the mounting frame via a positioning frame. A connecting member is fixedly installed at the lower end of the connecting shaft. A toothed plate is rotatably installed at the end of the connecting member away from the connecting shaft. The toothed plate meshes with the driven gear. A limiting member is slidably installed on the toothed plate. A connecting frame is fixedly installed on the limiting member. The connecting frame is rotatably connected to the fixed shaft.

[0008] Preferably, the fixed shaft is fixedly installed in the middle position of the mounting plate, and the fixed shaft and the rotation center of the cleaning cylinder are on the same axis. Intermediate shafts are rotatably installed on both sides of the mounting plate. A main gear is fixedly installed on the intermediate shaft, and a driven gear is fixedly installed at the upper end of the threaded sleeve. The driven gear meshes with the main gear.

[0009] Preferably, a transmission component is provided between the upper ends of the intermediate shaft, and transmission wheels are fixedly installed on the upper ends of both the intermediate shaft and the connecting shaft, with transmission belts sleeved around adjacent transmission wheels.

[0010] Preferably, a water inlet pipe is fixedly installed on the cleaning cylinder at a position corresponding to the position above each group of control components, and a water outlet pipe is fixedly installed on the cleaning cylinder at a position symmetrical to the water inlet pipe.

[0011] Preferably, a side drive shaft is rotatably mounted on the control component, one end of the side drive shaft extends into the control component and is fixedly mounted with a side gear, the side gear being connected to the inner ring of the gear ring, and a micro motor is fixedly mounted on the control component, the output end of the micro motor being fixedly connected to the side drive shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In this invention, through the cooperation between the control components and the positioning ring, the instruments to be cleaned are fixed below the positioning ring by the mounting ring, so that the instruments are suspended below the positioning ring. This suspension method reduces the contact area between the instruments themselves and the cleaning frame, ensuring the contact area between the instruments and the cleaning fluid during the cleaning process. During the downward movement, the distance sensor on the positioning ring continuously measures the distance between it and the mounting plate. Each time the instruments move to the position of the next set of control components, the immersion depth of the instruments increases, and new cleaning fluid is replaced each time, so the upper layer of cleaning wastewater will not contaminate the lower layer of cleaning fluid, until the instruments are completely submerged in the immersion tank. After cleaning, the positioning ring moves upward, directly bringing the instruments out of the cleaning tank, realizing segmented cleaning of the instruments, reducing the impurity content in the cleaning fluid that finally completely submerges the instruments, improving the cleaning quality of the instruments, and reducing the probability of the instruments re-adhering to dirt during the upward movement of the positioning ring. Moreover, after the positioning ring pulls the instruments, the instruments always remain in a suspended state, and the cleaning fluid on the surface of the instruments is more easily drained, thoroughly removing surface water stains after cleaning and avoiding contamination and corrosion of the user's hands.

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.

[0018] Please see Figures 1-6 The present invention provides a technical solution: A cleaning device for intensive care unit nursing includes a mounting frame 1 and a mounting plate 17. The mounting plate 17 is fixed above the mounting frame 1. A cleaning cylinder 2 is rotatably mounted on the mounting frame 1. A driven gear 6 is fixedly mounted on the upper end of the cleaning cylinder 2. Multiple control components 5 are fixedly mounted on the cleaning cylinder 2. A movable partition 24 is provided inside the control component 5, which longitudinally divides the cleaning cylinder 2 into multiple sections. Threaded sleeves 19 are rotatably mounted on both ends of the mounting plate 17. A threaded rod 7 is threadedly connected inside the threaded sleeve 19. A positioning ring 10 is fixedly mounted on the lower end of the threaded rod 7. Multiple mounting rings 11 are fixedly mounted on the lower surface of the positioning ring 10. A transmission structure is provided between the threaded sleeve 19 and the driven gear 6. The transmission structure can drive the driven gear 6 to reciprocate while driving the threaded sleeve 19 to rotate continuously.

[0019] Among them, the control components 5 are evenly distributed on the cleaning cylinder 2. A gear ring 27 is rotatably installed inside the control components 5. An inner fixed seat 29 is fixedly installed in the middle of the gear ring 27. A positioning shaft 30 is fixedly installed on the inner fixed seat 29. One end of the movable partition 24 is rotatably connected to the positioning shaft 30. A driving component 28 is rotatably installed on the gear ring 27. The end of the driving component 28 away from the gear ring 27 is rotatably connected to the movable partition 24.

[0020] The transmission structure includes a connecting shaft 8 and a fixed shaft 23. Two sets of connecting shafts 8 are rotatably connected to the mounting frame 1 at opposite positions. The connecting shafts 8 are rotatably connected to the mounting frame 1 through a positioning frame. A connecting member 13 is fixedly installed at the lower end of the connecting shaft 8. A toothed plate 12 is rotatably installed at the end of the connecting member 13 away from the connecting shaft 8. The toothed plate 12 meshes with the driven gear 6. A limiting member 22 is slidably installed on the toothed plate 12. A connecting frame 9 is fixedly installed on the limiting member 22. The connecting frame 9 is rotatably connected to the fixed shaft 23.

[0021] The fixed shaft 23 is fixedly installed in the middle position of the mounting plate 17. The fixed shaft 23 and the rotation center of the cleaning cylinder 2 are on the same axis. The intermediate shaft 21 is rotatably installed on both sides of the mounting plate 17. The main gear 20 is fixedly installed on the intermediate shaft 21. The driven gear 18 is fixedly installed on the upper end of the threaded sleeve 19. The driven gear 18 meshes with the main gear 20.

[0022] Among them, a transmission component 16 is provided between the upper ends of the intermediate shaft 21, and a transmission wheel 15 is fixedly installed on the upper ends of both the intermediate shaft 21 and the connecting shaft 8. A transmission belt 14 is sleeved on the adjacent transmission wheel 15.

[0023] Among them, an inlet pipe 3 is fixedly installed on the cleaning cylinder 2 at the position corresponding to the position above each group of control components 5, and an outlet pipe 4 is fixedly installed on the cleaning cylinder 2 at the position symmetrical to the inlet pipe 3.

[0024] Among them, a side drive shaft 25 is rotatably mounted on the control component 5, one end of the side drive shaft 25 extends into the control component 5 and a side gear 26 is fixedly mounted thereon, the side gear 26 is connected to the inner ring of the gear ring 27, a micro motor is fixedly mounted on the control component 5, and the output end of the micro motor is fixedly connected to the side drive shaft 25.

[0025] The mounting plate 17 is fixedly mounted with a drive motor, which is fixedly connected to the intermediate shaft 21. The mounting bracket 1 is equipped with a control motherboard, and the positioning ring 10 is equipped with a distance sensor. The control motherboard is connected to the distance sensor and the micro motor via Bluetooth.

[0026] In this invention, the instruments to be cleaned are fixed below the positioning ring 10 by the mounting ring 11, so that the instruments are suspended below the positioning ring 10 (eliminating the contact area between the instruments and the cleaning frame, ensuring the contact area between the instruments and the cleaning fluid during the cleaning process). Then, the drive motor is turned on, and the drive motor drives the intermediate shaft 21 to rotate. The rotation of the intermediate shaft 21 drives the main gear 20 to rotate, and the rotation of the main gear 20 drives the meshing driven gear 18 to rotate. The rotation of the driven gear 18 drives the threaded sleeve 19 to rotate. The rotation of the threaded sleeve 19 interacts with the threads on the threaded rod 7, driving the threaded rod 7 to move downward. The downward movement of the threaded rod 7 drives the positioning ring 10 to move downward, thereby causing the positioning ring 10 to move the instruments to be cleaned on it towards the cleaning cylinder 2 (initially, the movable partitions 24 are all in a closed state). During the downward movement, the distance sensor on the positioning ring 10 continuously measures the distance between it and the mounting plate 17. The controller controls the first set of water inlet pipes 3 to enter water according to the distance, and the lower end of the instruments is immersed in the first set of movable partitions. The lower end of the instrument is cleaned in the cleaning solution above plate 24. After cleaning, the wastewater is discharged through the outlet pipe 4. When the lower end of the instrument moves to the position of the first set of movable partitions 24, the control unit controls the micro motor to rotate, causing the movable partitions 24 to spread out (at this time, the wastewater has been discharged). Then the positioning ring 10 continues to move down. Each time it moves to the position of the next set of control components 5, the immersion depth of the instrument increases, and new cleaning solution is replaced each time. The upper layer of cleaning wastewater will not contaminate the lower layer of cleaning solution until the instrument is completely submerged in the immersion cylinder. After cleaning, the positioning ring 10 moves up and directly takes the instrument out of the cleaning cylinder 2, realizing segmented cleaning of the instrument. This reduces the impurity content in the cleaning solution that finally completely submerges the instrument, improves the cleaning quality of the instrument, and reduces the probability of the instrument re-adhering to dirt during the upward movement of the positioning ring 10. After the positioning ring 10 pulls the instrument, the instrument always remains in a suspended state, and the cleaning solution on the surface of the instrument is more easily drained, thoroughly removing surface water stains after cleaning the instrument and avoiding contamination and corrosion of the user's hands.

[0027] In this invention, during cleaning, the intermediate shaft 21 rotates, driving the connecting shaft 8 to rotate via the transmission wheel 15 and the transmission belt 14. The rotation of the connecting shaft 8 causes the connecting member 13, which is fixedly connected to it, to rotate. The rotating connecting member 13 moves the toothed plate 12. Under the traction of the connecting member 13 and the limiting action of the connecting frame 9, the toothed plate 12 continuously moves in an arc-shaped trajectory on the surface of the driven gear 6. This causes the toothed plate 12 to drive the driven gear 6 to rotate back and forth continuously. The reciprocating rotation of the driven gear 6 drives the cleaning cylinder 2 to rotate back and forth. The small-angle reciprocating rotation of the cleaning cylinder 2 causes the cleaning fluid to come into more intense contact with the instrument surface, so that the dirt adhering to the instrument surface can be removed more thoroughly.

[0028] In this invention, through the cooperation between the control component 5 and the positioning ring 10, the instruments to be cleaned are fixed below the positioning ring 10 by the mounting ring 11, so that the instruments are suspended below the positioning ring 10. The suspension method can eliminate the contact area between the instrument itself and the cleaning frame, ensuring the contact area between the instrument and the cleaning fluid during the cleaning process. During the downward movement, the distance sensor on the positioning ring 10 continuously measures the distance between it and the mounting plate 17. Each time it moves to the position of the next set of control components 5, the immersion depth of the instrument increases, and new cleaning fluid is replaced each time, so the upper layer of cleaning wastewater will not contaminate the lower layer of cleaning fluid, until the instrument is completely submerged in the immersion tube. After cleaning, the positioning ring 10 moves upward, directly taking the instrument out of the cleaning tube 2, realizing segmented cleaning of the instrument, reducing the impurity content in the cleaning fluid that finally completely submerges the instrument, improving the cleaning quality of the instrument, and reducing the probability of the instrument re-adhering to dirt during the upward movement of the positioning ring 10. Moreover, after the positioning ring 10 pulls the instrument, the instrument always remains in a suspended state, and the cleaning fluid on the surface of the instrument is more easily drained, thoroughly removing surface water stains after cleaning the instrument and avoiding contamination and corrosion of the user's hands.
