Description

Technical Field

[0001] The invention relates to a medical system, in particular to a waste liquid collecting device used for collecting waste liquid generated during medical treatment. Background Art

[0002] During certain surgical procedures, liquid, semi-solid and solid wastes are inevitably generated. Specifically, these include body fluids, such as blood, and perfusion solutions introduced into the surgical site during surgery. In addition, solid and semi-solid wastes generated during surgery include tissue fragments and small pieces of surgical materials that may remain in the body. Ideally, wastes should be collected as soon as they are generated so that they do not contaminate the surgical site or become biohazards in the operating room or other locations where the surgical procedure is performed.

[0003] In the prior art, there are a variety of waste liquid collection and treatment systems that can be used by medical staff to collect waste liquid generated during surgery or after surgery. The principle is mainly to use a vacuum source to generate suction force to suck the waste liquid 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, thereby sucking the waste liquid into a specific collection container through the pipeline contacting the surgical site.

[0004] In the prior art, in the medical waste liquid collection and treatment system, the waste liquid material is collected in a waste liquid collection container connected to a vacuum source. The waste liquid collection container is generally installed on a portable trolley with wheels for easy movement and transportation. Generally speaking, during the suction process, when the storage volume of the waste liquid collection container reaches a predetermined volume, the waste liquid collection container needs to be emptied. The early prior art practice is to push the waste liquid collection device to the docking station and empty and clean it. After the waste liquid collection unit is docked to the docking station, it begins to be emptied. Once emptied, the waste liquid collection container is cleaned by the cleaning system through disinfection and cleaning. In a series of medical processes, each process needs to be emptied. The frequent operation of pushing the waste liquid collection device to the docking station each time brings a lot of inconvenience to the user and affects the progress of medical treatment. Therefore, in response to this technical defect, a transfer device specially used to transport the waste liquid from the waste liquid collection device to the docking station has been developed, that is, a docking device specially used to transport the waste liquid in the waste liquid collection device. The device usually includes two connectors that are docked with the two connectors of the waste liquid collection device to form a liquid path connection. One liquid path is used to transfer the waste liquid from the waste liquid collection device to the docking device, and the other liquid path is used to clean the waste liquid collection container of the waste liquid collection device. In the prior art, after the docking device extracts the waste liquid from the waste liquid collection device, the waste liquid needs to be sent to the treatment station for disinfection treatment, and the waste liquid can only be discharged after disinfection. Therefore, when using this equipment, an additional disinfection station is required to cooperate in order to complete the treatment and discharge of the waste liquid. Summary of the invention

[0016] Furthermore, the disinfection gas circuit is also provided with a disinfection control valve, and the disinfection control valve is used to control the on-off of the disinfection gas circuit.

[0017] Furthermore, the ozone generator is connected to a disinfection air pump, and the disinfection air pump is used to pressurize the disinfection air circuit so that the ozone gas is fully dissolved in the waste liquid.

[0018] Furthermore, the exhaust port of the disinfection air pump is connected to a silencer.
