Description

Anti-backflow metering drainage bag

Technical Field

The invention relates to the technical field of medical suction instruments, in particular to an anti-backflow metering drainage bag.

Background

The drainage bag is a common medical appliance and is mainly used for external drainage and body fluid collection after operations such as urinary system operation, abdominal cavity operation and the like. In many cases, it is desirable to meter the amount of fluid drained. The prior art measures the amount of drainage fluid in two main ways. One is by weight. For example, chinese patent document CN 209122992U discloses a medical suspension type bluetooth gravity sensing measurement drainage bag, which is provided with a suspension type gravity sensing device, and can count the weight and volume of drainage liquid and upload to an intelligent terminal, but has a complex structure and a high cost. Chinese patent document CN207734391U adopts a method of installing a weighing spring scale, which can reduce the cost, but has a large error. The other is by volume measurement. For example, chinese patent document CN 203235061U discloses a disposable drainage bag with accurate measurement, which is based on the original drainage bag, a measurement bag with a capacity of 100ml is separated from one side of the drainage bag body, so as to divide the drainage bag body into a measurement bag and a liquid storage bag which are arranged side by side, and the measurement bag has a small cross-sectional area, so that the accurate measurement can be provided after filling liquid. The disadvantages of the scheme are that: (1) the measuring bag is positioned on the side surface, when the drainage bag is used, the whole drainage bag body is easy to incline due to uneven stress, so that the drainage tube is influenced to smoothly drain liquid; (2) the drainage liquid in the measuring bag is inconvenient to be converged into the liquid storage bag for temporary storage.

In order to ensure that the drainage liquid can smoothly enter the metering bag, when the first hanging lug is used for hanging, the drainage branch pipe on the upper edge of the metering bag is used for drainage, and the drainage branch pipe on the lower edge of the metering bag is sealed by a branch pipe clamp. When the second hanging lug is used for hanging, the drainage branch pipe on the lower edge of the metering bag is used for drainage, and the drainage branch pipe on the upper edge of the metering bag is sealed by a branch pipe clamp.

As a further improvement, the drainage tube is provided with a U-shaped sleeve, and both sides of the U-shaped sleeve are provided with drainage tube bayonets for the drainage tube to be clamped in. The drainage tube can be clamped into or pulled out of the bayonet of the drainage tube. When the first hanging lug and the second hanging lug are used alternately, the U-shaped sleeve can prevent the drainage tube from being directly bent at a certain point so as to influence the smoothness of the drainage tube.

As a refinement, the metering bag is provided with scale marks.

As a further improvement, the scale marks on the metering bag are arranged left and right.

As a further improvement, a metering bag bayonet used for clamping the metering bag is formed in the middle of the U-shaped sleeve. The metering bag bayonet can be clamped at different positions of the metering bag, and the terminal position of the drainage liquid can be conveniently and visually indicated without observing scale marks.

As a further improvement, the longitudinal width of the metering bag opening is larger than that of the metering bag, and the metering bag opening is clamped outside the metering bag and plays a role in adjusting the actual volume of the metering bag.

In conclusion, the drainage bag has the advantages of simple structure and convenience in manufacturing, the drainage bag is not prone to tilting during metering and drainage, the U-shaped sleeve can adjust the actual volume of the metering bag and visually indicate the drainage end point, drainage liquid can conveniently converge into the liquid storage bag after drainage is finished, and the drainage liquid in the liquid storage bag is not prone to flowing back to the drainage tube.
