Description
Technical Field
The utility model relates to the field of medical waste liquid treatment, in particular to waste liquid collecting equipment.
Background
During the performance of a particular surgical procedure, liquid, semi-solid and solid waste fluids, including in particular body fluids, such as blood, and perfusion solutions introduced into the surgical site during the procedure, are inevitably produced, and in addition, solid and semi-solid waste fluids produced during the procedure include tissue fragments and small pieces of surgical material that may remain in the body site. Ideally, the waste fluid is collected once it is produced so that it does not contaminate the surgical site or become a biohazard to the operating room or other site where the surgical procedure is performed.
In the prior art, there are a variety of waste fluid collection and treatment systems available for medical personnel to collect waste fluids generated during a procedure after or after the procedure has been performed. The principle is mainly that waste liquid generated at the operation site is sucked into a specific collection container by the suction force generated by a vacuum source. That is, upon system activation, the suction force generated by the vacuum source reaches the surgical site, drawing waste fluid through the tubing that the surgical site contacts into a specific collection container. In a medical waste collection and treatment system, waste material is collected in a waste collection container connected to a vacuum source. One scheme in the prior art is that a large-capacity waste liquid collecting container is adopted to suck and store waste liquid, and the larger the capacity is, the lower the precision of the scale of the container is, which is not favorable for accurately calculating the volume of the waste liquid; meanwhile, in the medical process, medical staff need to scan the waste liquid collecting container to estimate the amount of the waste liquid extracted subsequently, so that the operation can be controlled, but the larger the volume of the container is, the worse the volume intuitiveness is, and the estimation is not facilitated. However, when a container with a small volume is directly used, although it is easy to visually predict, the container will fill up more quickly, which may lead to interruption of the surgical procedure to empty the waste collection container, and the middle of the surgical procedure may cause inconvenience and risk to the treatment. While both large and small containers have the disadvantage of not being able to select different volumes to perform depending on the type of procedure.
In order to solve the technical problem, it is proposed to use two waste liquid collecting containers with different volumes to realize the visual estimation and accurate measurement by using a waste liquid collecting container with a small volume, and to realize the storage of a large amount of waste liquid by using a waste liquid collecting container with a large volume, as described in CN102512716B patent, the two waste liquid collecting containers are respectively connected with a negative pressure source by gas circuits, the negative pressure source can provide negative pressure for the two waste liquid collecting containers at the same time, during the use, only when the waste liquid collecting container with a small volume discharges liquid to the waste liquid collecting container with a large volume, the electromagnetic valve between the two waste liquid collecting containers is opened to communicate the two waste liquid collecting containers, therefore, the pressures in the two waste liquid collecting containers are usually different, after the electromagnetic valve is opened, the two waste liquid collecting containers need to balance the pressure first, if the pressure difference between the two waste liquid collecting containers is too large, for example, the waste liquid collecting container with a small volume above is operated under high negative pressure, following large-volume waste liquid collecting container does not have pressure, and the two is after the intercommunication, because the quick upflow of the gas in following large-volume waste liquid collecting container can cause the liquid production liquid in the little volume waste liquid collecting container to explode, causes the influence to level sensor wherein, causes the injury to the valve simultaneously to bring the interference for the user. The pipeline that two waste liquid collection containers and negative pressure source gas circuit are connected all is equipped with the check valve in CN102512716B, can't carry out the gas circuit intercommunication when making the solenoid valve between two waste liquid collection containers close, pressure differential between two waste liquid collection containers when collecting the liquid to big volumetric waste liquid collection container in order to reduce little volumetric waste liquid collection container, need provide the negative pressure for two waste liquid collection containers simultaneously, because the negative pressure source need provide the negative pressure for two cavities simultaneously, and need accord with the requirement of regulation to high negative pressure, need to install the bigger negative pressure pump of power, powerful negative pressure pump is bulky, and is heavy, cause equipment huge, the big cost of manufacturing of noise is expensive simultaneously.
