Description

Technical Field

[0001] This invention relates to the medical field, specifically to a medical device cleaning and care apparatus. Background Technology

[0002] Medical instruments require thorough cleaning and disinfection after use to prevent cross-infection. Currently, most medical instrument cleaning devices on the market integrate soaking, rinsing, and drying processes into the same chamber, lacking effective isolation between processes. This can easily lead to cross-contamination between cleaning and disinfecting solutions, affecting the cleaning and disinfection effect. Although some devices integrate multiple processes, manual transfer of instruments between different treatment areas is required, which is cumbersome and increases the risk of secondary contamination. While some existing technologies use lifting mechanisms to drive the cleaning basket to move up and down in the disinfecting solution, they often only achieve a single processing function and fail to rationally partition the soaking, rinsing, and drying processes in space and automate the sequential connection. In addition, traditional devices lack auxiliary cleaning methods in the soaking stage, resulting in limited effectiveness in removing stubborn stains from the surfaces and crevices of complex medical instruments. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide a medical device cleaning and care device that addresses the above-mentioned shortcomings of the prior art, and solves the problems of complicated procedures, easy cross-contamination and need for manual transfer in traditional cleaning devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a medical device cleaning and care device, comprising a main component, the main component comprising a cleaning tank, and lifting components disposed inside and outside the cleaning tank;

[0005] The lifting assembly includes a forward and reverse motor fixedly installed on the outside of the cleaning tank. A threaded rod is fixedly connected to the output end of the forward and reverse motor. A slide is rotatably connected to the outer side of the threaded rod so that the slide moves upward when the forward and reverse motor is working. A receiving rod is fixedly connected to the top of the slide. A support basket for placing medical instruments is fixedly connected to the end of the receiving rod away from the slide. The support basket is located inside the cleaning tank and has a mesh screen fixedly connected to its sides and bottom.

[0006] The cleaning box is also equipped with a rinsing component in the middle for rinsing and cleaning medical instruments inside the support basket.

[0007] The upper part of the cleaning box is also equipped with a drying component for drying medical instruments after cleaning.

[0008] Preferably, a glass observation plate is fixedly connected to the front of the cleaning box, an ultrasonic generator is fixedly connected to the lower part of the side wall of the cleaning box, and a drain pipe is fixedly connected to the bottom of the cleaning box.

[0009] Preferably, the rinsing assembly includes a water storage tank, which is fixedly connected to the middle of the outer side of the cleaning tank. A guide pipe is fixedly connected to the top of the water storage tank, and a pump body is fixedly installed on the outer side of the guide pipe. An inner plate is fixedly connected to the end of the guide pipe away from the water storage tank. The inner plate is located in the side wall of the cleaning tank, and nozzles are fixedly connected at equal intervals on the front of the inner plate.

[0010] Preferably, the drying assembly includes a side-mounted box, which is fixedly connected to the upper side wall of the washing box. A fan is fixedly installed on the back of the side-mounted box, and a heat-conducting pipe is fixedly installed on the front of the side-mounted box.

[0011] Preferably, the cleaning and care device further includes an exhaust gas treatment component, which includes a negative pressure fan fixedly installed on the top of the cleaning box and a filter box disposed on the outside of the cleaning box; the air inlet of the negative pressure fan is connected to the upper space of the cleaning box through an exhaust pipe, and its air outlet is connected to the filter box through an exhaust pipe; the output end of the positive and negative motors is also fixedly connected to a drive gear, which is connected to the impeller shaft of the negative pressure fan through a transmission gear set; when the positive and negative motors drive the threaded rod to rotate, the negative pressure fan is driven to operate synchronously through the drive gear and the transmission gear set, so as to draw the humid and hot exhaust gas and volatile gas generated in the cleaning and drying process in the cleaning box to the filter box for purification treatment.

[0012] Preferably, the filter box is provided with an activated carbon adsorption layer and a hydrophobic and breathable membrane layer in sequence along the gas flow direction; the exhaust end of the exhaust pipe extends into the bottom of the filter box and is immersed in the absorbent liquid contained inside; and a purification exhaust port is provided on the top of the filter box.

[0013] Preferably, an ultrasonic generator is provided at the bottom of the cleaning tank, and the ultrasonic generator operates at a frequency of kHz to kHz. When the support basket is driven down to the lower soaking position by the lifting assembly, the ultrasonic generator is activated to apply ultrasonic vibration to the medical instruments soaked in the cleaning solution in the support basket, so that the dirt on the surface and in the gaps of the instruments is loosened and peeled off. Then, the support basket is driven up to the middle rinsing position by the lifting assembly, and the rinsing assembly washes away the loosened dirt.

[0014] The beneficial effects of this invention are as follows:

[0015] I. This invention uses a lifting assembly to drive the support basket from bottom to top, sequentially passing through the lower soaking area, the middle rinsing area, and the upper drying area. This allows the soaking, rinsing, and drying processes to be connected sequentially and spatially isolated in the vertical direction, completely avoiding cross-contamination between processes. At the same time, the lifting assembly adopts a screw-slide transmission structure, which has high displacement control accuracy and good self-locking performance, and can accurately stop at each preset workstation. Combined with the control panel, it realizes fully automated sequential operation without manual intervention in transportation, effectively reducing the risk of infection for operators from contact with contaminated equipment.

[0016] II. This invention applies ultrasonic vibrations to the medical instruments being immersed using a lower ultrasonic generator. The microscopic impact force generated by the cavitation effect loosens and peels away stubborn dirt from the inner walls of the tubes and the gaps between the joints. This is then combined with the high-pressure spray from the middle rinsing component to forcibly flush away the loosened dirt. The two work together from bottom to top, significantly improving the cleaning effect of instruments with complex structures. The upper drying component uses a fan and heat pipes to generate forced convection hot air. The hot and humid air is naturally discharged upwards without contaminating the rinsed instruments below. The upward airflow direction is consistent with the movement direction of the instruments, resulting in high drying efficiency and low energy consumption.

[0017] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0024] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0025] The present invention proposes a medical device cleaning and care device, including a main component 1, the main component 1 including a cleaning tank 11, and a lifting component 2 disposed inside and outside the cleaning tank 11.

[0026] The lifting assembly 2 includes a forward and reverse motor 21 fixedly installed on the outside of the cleaning tank 11. A threaded rod 211 is fixedly connected to the output end of the forward and reverse motor 21. A slide 22 is rotatably connected to the outside of the threaded rod 211 so that when the forward and reverse motor 21 is working, it drives the slide 22 to move upward. A receiving rod 221 is fixedly connected to the top of the slide 22. A support basket 23 for placing medical instruments is fixedly connected to the end of the receiving rod 221 away from the slide 22. The support basket 23 is located inside the cleaning tank 11, and a mesh screen 231 is fixedly connected to its four sides and bottom.

[0027] The middle part of the cleaning tank 11 is also equipped with a rinsing component 3 for rinsing and cleaning medical instruments in the support basket 23;

[0028] The upper part of the cleaning box 11 is also equipped with a drying component 4 for drying medical instruments after cleaning.

[0029] After the forward and reverse motor 21 is connected to the power supply and started, its output end drives the threaded rod 211 to rotate forward around its own axis. Since the slide 22 and the threaded rod 211 are connected by a threaded engagement, and the slide 22 cannot rotate with the threaded rod 211 under the constraint of the connecting rod 221, the forward rotation of the threaded rod 211 is converted into a linear motion of the slide 22 from bottom to top along the axis of the threaded rod 211. When the slide 22 moves from a low position to a high position in the vertical direction, it drives the support basket 23 to move synchronously from bottom to top inside the cleaning tank 11 through the connecting rod 221. The forward and reverse motor starts the support basket 23. First, the device is positioned in the lower soaking area of ​​the cleaning tank 11. After the soaking process is completed, the forward and reverse motor 21 is started to rotate in the forward direction, driving the support basket 23 to rise to the middle rinsing area. After the rinsing process is completed, the forward and reverse motor 21 is started again to continue rotating in the forward direction, raising the support basket 23 to the upper drying area. This realizes the automated sequential transfer of medical instruments from bottom to top through the three processes of soaking, rinsing, and drying. After all processes are completed, the forward and reverse motor 21 rotates in the reverse direction, lowering the support basket 23 directly from the upper drying area to the upper opening of the cleaning tank 11, making it easy for operators to take out the processed medical instruments.

[0030] The high-speed rotation of the forward and reverse motor 21 is converted into a smooth, low-speed lifting motion of the support basket 23 by a screw-slide transmission mechanism. Compared with traditional cylinder lifting or chain lifting methods, this structure has higher displacement control accuracy and better self-locking performance, and can accurately position the support basket 23 to various preset heights within the cleaning tank 11. The support basket 23 is driven by the same lifting assembly 2 to pass through three processes from bottom to top: soaking, rinsing, and drying. This ensures that the cleaning process strictly follows the principle of removing contaminants from heavy to light. The lower soaking uses ultrasound and cleaning fluid to fully loosen stubborn stains, the middle rinsing forcibly removes the loosened dirt, and the upper drying quickly dries the cleaned utensils. The three processes are arranged sequentially from bottom to top in space, completely avoiding secondary contamination of the upper utensils by the dirt removed during the cleaning process. At the same time, the forward and reverse rotation control of the forward and reverse motor 21 is simple and reliable, and it is easy to automatically set the dwell time of each process through the control panel, providing a foundation for the fully automatic sequential operation of the entire device.

[0031] A glass observation panel 111 is fixedly connected to the front of the cleaning box 11, an ultrasonic generator 12 is fixedly connected to the lower part of the side wall of the cleaning box 11, and a drain pipe 13 is fixedly connected to the bottom of the cleaning box 11.

[0032] The rinsing assembly 3 includes a water storage tank 31, which is fixedly connected to the middle of the outer side of the cleaning tank 11. A guide pipe 32 is fixedly connected to the top of the water storage tank 31. A pump body 321 is fixedly installed on the outer side of the guide pipe 32. An inner plate 33 is fixedly connected to the end of the guide pipe 32 away from the water storage tank 31. The inner plate 33 is located in the side wall of the cleaning tank 11. Spray nozzles 331 are fixedly connected at equal intervals on the front of the inner plate 33.

[0033] When the support basket 23 rises from the lower soaking area to the middle rinsing area of ​​the cleaning tank 11 under the drive of the lifting component 2 and stops moving, the pump body 321 is connected to the power supply and starts to operate, generating negative pressure inside the pump body 321. This draws the pre-stored cleaning fluid from the water tank 31 into the pump body 321 through the guide pipe 32 and applies pressure. The pressurized cleaning fluid flows along the guide pipe 32 under the continuous push of the pump body 321 and is finally delivered to the inner tray 33. After entering the inner tray 33, the cleaning fluid is evenly distributed in its internal cavity and then flows from the evenly spaced... The nozzle 331 sprays out at high speed, forming multiple high-pressure water curtains with a certain impact force; the high-pressure cleaning fluid passes through the mesh of the strainer 231 and impacts the surface of the medical instruments in the support basket 23 from a horizontal or oblique direction, peeling off and washing away the dirt loosened by the soaking in the lower part; the waste liquid generated by rinsing flows downward under the action of gravity and falls into the bottom of the cleaning tank 11, where it merges with the waste liquid in the lower soaking pool and is discharged through the drain pipe 13; after the rinsing process is completed, the lifting component 2 is restarted, driving the support basket 23 to continue moving upward to the upper drying area.

[0034] The system employs a pump body 321 for pressurization, combined with equally spaced nozzles 331, to create a wide-coverage, uniformly impacted spray area in the center of the cleaning tank 11. This ensures that medical instruments in different positions within the support basket 23 are effectively rinsed. The rinsing assembly 3 is positioned above the soaking area, allowing the waste liquid generated during rinsing to flow naturally downwards into the bottom of the soaking area under gravity and be discharged, preventing it from splashing upwards and contaminating the drying area above. The three areas form a reasonable fluid flow layout in the vertical direction. The shearing force of the high-pressure water curtain effectively removes residual enzyme cleaning agent and loosened protein dirt adhering to the instrument surface after soaking, preventing dirt from re-adhering to the instrument surface and forming white spots or water stains after entering the upper drying area. The timing coordination between the pump body 321 and the forward and reverse motors 21 ensures that the spraying action automatically starts after the support basket 23 reaches the rinsing area, achieving automated connection between the rinsing process and the lifting action.

[0035] The drying assembly 4 includes a side-mounted box 41, which is fixedly connected to the upper side wall of the washing box 11. A fan 42 is fixedly installed on the back of the side-mounted box 41, and a heat-conducting pipe 43 is fixedly installed on the front of the side-mounted box 41.

[0036] When the support basket 23 continues to rise from the middle rinsing area to the upper drying area of ​​the washing box 11 under the drive of the lifting component 2 and stops moving, the fan 42 is connected to the power supply and starts to operate. Under the high-speed rotation of the impeller of the fan 42, external air is continuously drawn into the fan 42 and forms an airflow with a certain velocity. This airflow enters the internal cavity of the side box 41 under the push of the fan 42, and then flows through the heat-conducting pipe 43 fixedly installed on the front of the side box 41. The heat-conducting pipe 43 generates heat after being powered on, which in turn draws the airflow flowing over its surface. Heating to a preset temperature generates high-temperature hot air. Driven continuously by the fan 42, the hot air is blown out from the front of the side-mounted box 41 and enters the upper area of ​​the cleaning box 11. It forces convection heating on the medical instruments in the support basket 23 that is parked in this area, causing the residual rinsing liquid moisture on the surface of the instruments to evaporate quickly, achieving a drying effect. Because the hot air has a low density, the humid and hot air generated during the drying process naturally gathers upward and is discharged from the gap between the upper opening of the cleaning box 11 and the cover, instead of flowing back down to the middle rinsing area and the lower soaking area.

[0037] The hot air drying structure, combining a fan 42 and a heat pipe 43, significantly improves the drying rate and shortens the processing cycle for a single batch of instruments compared to simple natural air drying or static heating drying methods. The drying assembly 4 is positioned in the upper area of ​​the cleaning chamber 11, fully utilizing the natural upward movement of hot air to ensure even heat distribution within the upper area. Simultaneously, the humid air is expelled upwards, preventing contamination of the rinsed instruments below. The upward airflow aligns with the movement of the instruments, further enhancing drying efficiency and energy utilization. The heating temperature of the heat pipe 43 can be adjusted via a control panel according to the material tolerance of the medical instruments, making it suitable for drying instruments made of various materials such as metal, rubber, and plastic, demonstrating strong versatility.

[0038] It is clear that the transmission method of the threaded rod 211 is vertical drive and self-locking, so that the support basket (23) can be accurately suspended at the preset work position. By combining the self-locking threaded pair with the three-stage (soaking, rinsing, drying) work position, the stability of the position can be maintained without the need for an external braking device, which is a creative improvement in structure.

[0039] A design was introduced that uses a forward and reverse motor 21 to synchronously drive the exhaust gas treatment component. The power is split through the active gear and the transmission gear set. While the threaded rod 211 rotates, it drives the negative pressure fan 51 to draw in air. The single power source synchronously realizes lifting and exhaust gas collection, which is more compact, lower in cost, and the gear set transmission ratio is stable. It can ensure that the exhaust gas is extracted in time during the cleaning / drying process and avoid cross-contamination.

[0040] The ultrasonic generator 6 is more precisely matched with the three-stage "bottom-up" process flow. Ultrasonic cleaning is used in the lower soaking area, while rinsing is used in the middle. The two are spatially separated but sequentially connected, namely "soaking ultrasonic loosening - rising - high-pressure rinsing peeling".

[0041] The exhaust pipe 53 is laid along the inner wall of the cleaning box 11 so that the cleaning liquid in the cleaning box 11 is slightly heated during the exhaust process. That is, the air passing through the pipe wall during the exhaust process will generate friction, making the exhaust pipe 53 hot.

[0042] The lifting assembly 2 drives the support basket 23 vertically upwards through the lower soaking area, the middle rinsing area, and the upper drying area within the cleaning tank 11. This spatially separates the soaking, rinsing, and drying processes and ensures sequential connection in time. Each process's processing medium operates independently within its respective area, completely avoiding cross-contamination issues caused by mixing cleaning and disinfectant solutions in traditional multi-process operations within the same chamber. This significantly improves the cleaning and disinfection quality and safety of medical devices. The lifting assembly 2 employs a forward and reverse motor 21 driving a lead screw slide transmission structure, coupled with a self-locking design where the threaded rod 21's thread helix angle is less than the equivalent friction angle. This allows the support basket 23 to precisely stop at each preset station and maintain a stable position, combined with the preset programs on the control panel. It can achieve fully automated sequential operation without manual intervention during the entire transfer process. Operators only need to place the instruments at the beginning and remove them afterward, greatly reducing the chance of personnel coming into contact with contaminated instruments and effectively reducing the risk of cross-infection. An ultrasonic generator 6 is installed at the bottom of the cleaning tank 11. When the support basket 23 descends to the soaking position, the ultrasonic generator 6 is activated. The cavitation effect generated by the ultrasonic waves at a frequency of 20 to 40 kHz in the liquid applies a microscopic impact force to the surface of complex medical instruments and hard-to-reach areas such as gaps, blind holes, and inner walls of cavities, causing the stains to loosen and peel off. Subsequently, the lifting assembly 2 raises the support basket 23 to the middle rinsing position, where the high-pressure spray of the rinsing assembly 3 forcibly washes away the loosened dirt. The two work in succession from bottom to top. This system achieves a deep cleaning chain that combines ultrasonic loosening followed by high-pressure rinsing, making it particularly suitable for cleaning precision and complex instruments. Its cleaning effect far surpasses that of single cleaning methods. An active gear is added to the output of the forward and reverse motors 21, which is connected to the impeller shaft of the negative pressure fan 51 via a transmission gear set. When the forward and reverse motors 21 drive the threaded rod 211 to rotate, simultaneously lifting and lowering the support basket 23, they also drive the negative pressure fan 51. This promptly extracts the humid and hot exhaust gas, disinfection volatile gases, and odors generated during the cleaning and drying process in the cleaning box 11 to the filter box 52. The exhaust gas undergoes a triple purification process: adsorption by the activated carbon adsorption layer, interception by the hydrophobic and breathable membrane layer, and dissolution by the absorbent liquid before being discharged. A single power source simultaneously drives both the lifting actuator and the exhaust gas treatment mechanism, eliminating the need for a separate exhaust gas treatment system. The motor is more compact, has lower manufacturing costs, and consumes less energy. The stable gear ratio ensures the synchronous coordination of exhaust gas extraction and cleaning and drying processes. The upper drying component 4 uses a fan and heat pipes to generate forced convection hot air. When the support basket 23 enters the drying area from bottom to top, the hot air blows from bottom to top onto the surface of the appliance. The humid air is naturally discharged upwards. The upward airflow direction is completely consistent with the movement direction of the support basket 23, which is conducive to the hot air fully covering all surfaces of the appliance, making the drying uniform and the heat exchange efficiency high. At the same time, the natural upward trend of the humid air is consistent with the forced exhaust direction of the fan, which reduces the power consumption of the fan and has a significant energy-saving effect. The upward flow of hot air without sinking ensures the temperature stability of the rinsed area below and prevents the rinsed appliances from being wetted again.The exhaust gas drawn by the negative pressure fan 51 is adsorbed by the activated carbon adsorption layer in the filter box 52 to adsorb volatile organic compounds, and the hydrophobic and breathable membrane layer intercepts water vapor and particles. Then, it is immersed in the absorption liquid at the exhaust pipe 54 for water washing and dissolution, and finally, clean gas is discharged from the purified exhaust port. This triple purification mechanism ensures that harmful components in the exhaust gas are fully removed, meeting the environmental emission requirements of medical facilities, while avoiding direct exhaust gas emissions that could harm the health of operators. Furthermore, the overall structure arranges the soaking, rinsing, and drying functional areas vertically. The lifting component 2 is located outside the cleaning box 11, not occupying internal space. The power transmission mechanism is centrally located on one side of the cleaning box 11, resulting in a compact structure and convenient maintenance. The support basket 23 uses a mesh 231 structure around its perimeter and bottom, ensuring sufficient liquid contact with all surfaces during soaking and rinsing, and facilitating hot air circulation during drying. The overall space utilization is high, and the footprint is small, making it suitable for use in various medical institutions.
