Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a medical metering drainage device. Background Art

[0002] The medical metering drainage device is an important medical device, which is mainly used for measuring and collecting drainage fluid of patients in clinical practice. The medical metering drainage device is usually composed of a liquid inlet, a liquid outlet, a container, a partition, a scale, an overflow liquid storage container and a hook. A partition is provided in the container to divide the container into multiple chambers. A through hole is opened on the upper part of the partition to connect the chambers.

[0003] When using the existing medical metering drainage device, medical staff cannot visually check how much liquid is collected by the drainage device, and if the patient has too little fluid accumulation, it is easy to be mixed into the physiological saline, and the fluid accumulation cannot be effectively tested. Based on these problems, Chinese patent CN218075848U discloses a medical metering drainage device. When the volume collected in the metering chamber is relatively large, it can flow directly from the top of the partition into the pressure regulating chamber. The metering chamber and the pressure regulating chamber are both provided with metering scales accurate to milliliters, which can well enable medical staff to understand the volume of the collected solution. When the amount of fluid accumulation is small, all the fluid accumulation is retained in the metering chamber. After collection, the fluid accumulation is retained in a sterile bottle for clinical monitoring, which is beneficial for providing doctors with important reference indicators for the patient's disease condition.

[0004] The internal cavity of the drainage box body is a cube, and a vertical partition is installed inside the cavity. Therefore, there are many dead corners inside the drainage box body where residues are easily attached. At the same time, the outer shell structure of the drainage box body cannot be disassembled, which makes the cleaning work inside the drainage box body more difficult, which not only affects the continued use of the drainage device, but also increases the use cost of the drainage device.
