Description

Safety chest bottle

This creation is about breast bottles, and in particular about a safety breast bottle with safety functions.

A chest bottle is a container connected to a chest drainage device for collecting waste fluid. A chest bottle generally includes a collection chamber and a water seal chamber. The collection chamber is directly connected to the patient's chest with a pipe. The water seal chamber is filled with water. A water seal tube is installed in the water seal chamber. The upper end of the water seal tube is connected to the collection chamber with an additional pipe, and the lower end of the water seal tube is immersed in water. The water seal chamber is connected to a negative pressure source with a pipe. The negative pressure source can drive the waste fluid into the collection chamber and the air cannot pass through the water seal chamber into the collection chamber, thereby preventing air from entering the patient's chest cavity and causing pneumothorax.

However, in existing chest bottles, as long as the negative pressure source is removed (for example, when the negative pressure source is turned off or the chest bottle is replaced), the water in the water seal chamber will flow back through the water seal tube to the collection chamber. Once the water in the water seal chamber flows back into the collection chamber, it cannot flow back into the water seal chamber, causing the water level in the water seal chamber to drop, thereby causing the water seal to fail. Once the water seal fails, air will flow back through the water seal tube into the patient's chest cavity and cause pneumothorax. Therefore, existing chest bottles have a safety issue in that air will flow back through the water seal tube into the patient's chest cavity.

In view of this, the author has devoted himself to the research and application of the above existing technologies, trying his best to solve the above problems, which has become the goal of the author's improvement.

The invention provides a safety chest bottle, which can effectively prevent the water seal fluid from entering the collection chamber from the water seal chamber, thereby preventing the air from backflowing into the patient's chest cavity.
