Medical negative pressure drainage bag with accurate metering pipe

Abstract

The invention discloses a medical negative pressure drainage bag with an accurate metering pipe. The drainage bag comprises a drainage bag body, wherein a draining connector is formed in the upper end of the drainage bag body, and a discharge connector is formed in the bottom of the drainage bag body; the metering pipe is arranged in the drainage bag body; the top of the metering pipe is communicated with the inner cavity of the drainage bag body; and the bottom of the metering pipe is communicated with the discharge connector. According to the medical negative pressure drainage bag, accurate metering can be provided by virtue of the metering pipe, the draining amount of the drainage bag can be dynamically observed, negative pressure is generated by virtue of an external negative pressure ball, and negative pressure can be generated by manually pressing the negative pressure ball to perform draining. The medical negative pressure drainage bag is convenient to operate, and has a practical and reliable structure.

Description

technical field [0001] The invention relates to a drainage bag, in particular to a medical negative pressure drainage bag with a precise metering tube. Background technique [0002] At present, in surgical operations, drainage bags are often used for negative pressure drainage, and are widely used. The structure of the existing drainage bag is relatively simple, and an external negative pressure device is usually used to generate negative pressure to drain the liquid into the drainage bag. After use, the negative pressure device needs to be cleaned and disinfected, which also brings inconvenience to the nursing work. Although the current drainage bag is usually equipped with a scale, because of its soft material, there is a large error between the reading and the actual liquid volume, which brings inconvenience to the actual work and seriously affects the patient's later treatment. Contents of the invention [0003] In order to solve the above technical problems, the pres...
