[0002] Postoperative patients usually need drainage tubes for drainage, and the drainage fluid requires nurses to pour the drainage fluid for patients with indwelling drainage tubes one by one and accurately measure it. There are many types of drainage tubes on patients. Some have a small drainage volume and unclear scales. Nurses need to collect the fluid through a dressing bowl and then measure the flow rate by aspiration with a syringe, which is very troublesome. And the dressing bowl is easy to tip over and pollute the indoor environment. The Chinese utility model patent with application number 202120260188.9 discloses a centralized drainage fluid collection device that can accurately measure the amount of drainage fluid in patients, and can effectively reduce the risk of occupational exposure of medical staff.

[0003] The aforementioned centralized drainage fluid collection device can collect and measure drainage fluid. However, during use, it was discovered to have the following drawbacks: 1. The metering tube and the fluid bag require an on-off valve for control, which is cumbersome and increases manufacturing costs due to frequent operation; 2. The metering tube is equipped with a one-way valve, which increases costs and, when the fluid volume is low, corrodes, resulting in leakage issues; 3. In addition to the fluid storage bag, the device also includes a fluid storage barrel and a clamping tray, which is complex and hinders manufacturing costs. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a disposable drainage fluid collector, which eliminates the switch valve, one-way valve, liquid storage barrel and card plate, reduces manufacturing costs, simplifies the structure and can also realize the drainage fluid collection and measurement in batches, effectively solving the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a disposable drainage fluid collector, comprising an upper metering tube, the metering tube being in the shape of a cylindrical tube with an upper opening, and having a trumpet-shaped drainage portion at the upper opening, the outer surface of the metering tube being provided with a first vertical scale, and an arc-shaped handle being fixedly provided on the outer surface of the metering tube on one side of the first scale;
