Embodiment

[0043] Such as figure 1 As shown in a preferred embodiment of the present invention, the disposable self-control precise metering drainage bag includes a metering box body 100, and a liquid inlet pipe 110 and a liquid inlet 111 thereof are arranged at the top 140 of the metering box body. The top of 100 is also provided with air vent 120, and the bottom 150 of the metering box body is provided with a liquid discharge pipe 130 and is connected with a liquid storage container 400 through the liquid discharge pipe. Self-control drain line. The self-control liquid discharge pipeline is a double pipe structure, including a drainage pipe 210 whose lower end is connected to the liquid discharge pipe 130 at the bottom of the metering box body and a siphon pipe 220 adjacent to it and sharing a pipe wall 212. The shared pipe The wall 212 is a free end structure, and the siphon tube 220 and the drainage tube 210 communicate 230 at the free end structure.

Abstract

The invention discloses a disposable self-control precision metering drainage bag, which comprises a metering box body (100). A liquid inlet pipe (110) and a liquid inlet (111) are arranged on the top (140) of the metering box body; air vents (120) are formed on the upper part of the metering box body (100); the bottom (150) of the metering box body is provided with a liquid discharge pipe (130) and connected with a liquid storage container (400) through the liquid discharge pipe; and the metering box body (100) is provided with a self-control liquid discharge pipeline using the principle of siphon. The self-control liquid discharge pipeline comprises at least one siphon pipe (220) with an opening close to the bottom (150) of the metering box body and at least one drainage pipe (210) communicated with the liquid discharge pipe (130); and the siphon pipe (220) is communicated with the drainage pipe (210) on the top (230). The disposable self-control precision metering drainage bag solves the problem of accumulative calculation of drainage liquid and thus reduces labor intensity, can automatically discharge liquid without overflow of the liquid, and is easy to manufacture because of integrated forming of the self-control liquid discharge pipeline and the metering box.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a disposable self-controlled precision metering drainage bag. Background technique [0002] The continuous measurement and observation period of the traditional precision metering drainage bag is short, and the capacity of the metering box is the limit, usually 500ML. When the traditional precision metering drainage bag is in use, the drainage liquid enters the metering box made of hard material along the liquid inlet pipe through the liquid inlet, and the liquid volume is measured through the scale on the metering box, generally the maximum is 500ML; the metering box is connected to the liquid storage For the container, before the drainage fluid of the metering box reaches the rated capacity, it is necessary to regularly observe the drainage fluid volume, and write down the drainage capacity, then pour the drainage fluid into the liquid storage container and enter the re-measureme...
