Description

Waste Liquid Collection and Treatment System and Cleaning Method

[0001] This application claims the priority of the Chinese patent application with the application number 202410200318.8 and the title "Waste Liquid Collection and Treatment System and Cleaning Method" filed on February 22, 2024, and the entire content thereof is incorporated into this application by reference. Technical Field

[0002] The present invention relates to the technical field of medical devices, and particularly to a waste liquid collection and treatment system and a cleaning method. Background Art

[0003] During certain surgical procedures, it is inevitable to generate waste in the forms of liquids, semi-solids, and solids, such as human fluids like blood, perfusion solutions introduced into the surgical site during the operation, human tissue fragments, and small pieces of surgical materials, i.e., solid and semi-solid wastes generated during the surgical procedure. These wastes need to be collected in a timely manner to avoid soiling and contaminating the surgical site and to prevent them from becoming biological hazards in the operating room or other locations where the surgical procedure is performed. In the prior art, usually, a suction force is generated by a vacuum source to suck the wastes generated at the surgical site into a specific collection container. That is, after the system is started, the suction force generated by the vacuum source reaches the surgical site, and thus the wastes are sucked and flowed into the specific collection container through the pipeline in contact with the surgical site.

[0004] In a medical waste collection and treatment system, waste materials are collected in a waste collection container connected to a vacuum source. The waste collection container is generally installed on a portable trolley with wheels for easy movement and transportation. Generally, during the suction process, when the storage volume of the waste collection container reaches a predetermined volume, the waste collection container needs to be emptied. In the early prior art, the practice was to push the waste collection equipment to the docking station and empty and clean it. After the waste collection unit is docked to the docking station, it starts to be emptied. Once emptied, the waste collection container is cleaned by the cleaning system through disinfection and washing. Technical Problems

[0005] In a series of medical procedures, each procedure requires evacuation. The frequent operation of pushing the waste collection device to the docking station each time brings a lot of inconvenience to the user and affects the medical progress. Therefore, in view of this technical defect, a transfer device dedicated to transporting the waste of the waste collection device to the docking station has been developed, that is, a docking device dedicated to transporting the waste in the waste collection device. This device usually includes two connectors that dock with two connectors of the waste collection device to form a liquid path connection. One liquid path is used to transfer the waste of the waste collection device to this docking device, and the other liquid path is used to clean the waste collection container of the waste collection device. However, when cleaning, hot water above 40°C is usually required for cleaning, but many hospitals cannot provide such a large amount of hot water. Technical solution

The waste collection device 10 can be connected to an external suction pipeline (not shown in the figure) through a consumable cartridge. The external suction pipeline can be connected to a suction joint (not shown in the figure). The suction joint can be a separate joint or attached to a surgical device. The suction force of the suction pipeline can come from a vacuum source provided inside the waste collection device 10 or from an external vacuum source. The suction force at the suction joint transports the waste through the external suction pipeline into the waste collection container 15 of the waste collection device 10 for storage. After the docking device 30 docks with the waste collection device 10, it can empty the waste in the waste collection container 15 of the waste collection device 10 through the liquid discharge module 70 in the docking device 30 and form a flushing passage for cleaning the waste collection container 15 (see Figure 2) of the waste collection device 10, and use the flushing module 80 to flush the waste collection container 15. In this embodiment, the steam generation device 50 can be provided inside the docking device 30. It can be understood that in other embodiments, the steam generation device 50 can also be provided separately and outside the docking device 30, and the steam can be introduced into the waste collection container 15 through a pipeline.

The waste collection device 10 further includes a trolley housing 12, a trolley main frame 13, a traveling mechanism 14 provided at the bottom of the trolley main frame 13, and a trolley docking part 16 mounted on the trolley main frame 13. A support hanging rod 122 and a collection end display device 124 are also provided on the trolley housing 12. The waste collection container 15 is disposed inside the trolley housing 12.

[0051] In this embodiment, a magnetic stopper 126 is further provided on the trolley housing 12 of the waste collection device 10, and the magnetic stopper 126 is disposed on at least one side of the trolley docking part 16.

[0052] Specifically, a first anti-collision part 127 is further provided on the trolley housing 12, and the first anti-collision part 127 is located on both sides of the trolley docking part 16. Specifically, the first anti-collision part 127 can be an anti-collision roller.

[0054] In this embodiment, the trolley docking part 16 can be disposed at the bottom of the trolley main frame 16 for mating with the docking device 30. Specifically, the trolley docking part 16 forms a mating space 161 to accommodate the mating head 34 of the docking device 30. The first anti-collision part 127 is located on both sides of the mating space 161 to prevent the mating head 34 of the docking device 30 from colliding with the inner side wall of the mating space 161.

[0055] Specifically, a charging receiving part 162 is further provided in the mating space 161. The charging receiving part 162 can be a wireless charging receiving part 162 to achieve wireless charging.

[0056] Specifically, please refer to FIGS. 4 and 5. A steam discharge port is provided on the waste collection container 15, and an exhaust valve 151 is provided at the steam discharge port. The exhaust valve 151 includes an open state and a closed state to connect or disconnect the waste collection container 15 from the external environment, so as to discharge the steam of the waste collection container 15 when it is open, open to exhaust the steam in the waste collection container 15 after the pressure in the waste collection container 15 reaches a certain value, avoid the explosion of the waste collection container 15, and close it when sucking liquid to avoid affecting the sealing performance of the waste collection container 15. Specifically, the exhaust valve 151 can be a check valve, which automatically opens when the pressure in the waste collection container 15 reaches the set pressure of the check valve, otherwise the check valve closes. It can be understood that the exhaust valve 151 can also be other valves, such as an electromagnetic solenoid valve, and the exhaust valve 151 is controlled to be in an open or closed state by controlling whether to energize the electromagnetic solenoid valve. Specifically, when the exhaust valve 151 is a check valve, the exhaust valve 151 includes a valve seat 1511, a valve core 1513 movably arranged in the valve seat 1511, and a spring 1515. The two ends of the spring 1515 respectively abut against the valve seat 1511 and the valve core 1513, and the elastic force of the spring 1515 closes the check valve. When the pressure in the waste collection container 15 reaches the set pressure of the check valve, it overcomes the elastic force of the spring 1515 to open the check valve. Specifically, the steam discharge port can be provided on the tank cover 153 of the waste collection container 15. Of course, it can also be provided at any other position in gas circuit connection with the waste collection container 15.

The two steam female connectors 1603 are respectively connected to one waste collection container 15. The steam female connectors 1603 are closer to the outer side of the waste collection device 10 than the drainage female connector 1601 and the flushing female connector 1602. That is to say, when the waste collection device 10 is docked with the docking device 30, the docking device 30 first approaches the steam female connectors 1603. It can be understood that when there is one waste collection container 15, there is also one steam female connector 1603.
