Quantitative drainage bag

Abstract

The invention discloses a quantitative drainage bag, which comprises a bag body used to contain liquid. Scales for measuring volume are marked on the bag body. The inner chamber of the bag body is divided into a plurality of small units. The small units are connected together through channels. By adopting the structure, when in use, after liquid enters the bag body, the small units of the bag body are gradually filled with the liquid from bottom to top under the effect of gravity. Since the small units are arranged, the invention has the advantages that the deformation of the bag body is very small, the filling is even and the volume measurement of the bag body is accurate.

Description

technical field [0001] The invention belongs to a medical device, in particular to a drainage bag. Background technique [0002] Various drainage bags have been widely used clinically. Through clinical practice, although there are scales on the commonly used flat drainage bags, because they are made of soft materials, the readings are different from the actual liquid. There is a large error between the volumes, which brings some disadvantages to the actual work. For example, the urine output of some critically ill patients is one of the important diagnostic indicators. If the urine output cannot be accurately measured, it will not correctly reflect the condition and hinder the doctor's diagnosis. Contents of the invention [0003] The object of the present invention is to provide a quantitative drainage bag with accurate measurement in view of the defects of the above-mentioned prior art. [0004] The technical solution is as follows: a quantitative drainage bag, includi...
