Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a negative pressure suction barrel anti-falling device. Background Art

[0002] Negative pressure suction devices are used in respiratory medicine, ICUs, gastroenterology, general surgery, orthopedics, and operating rooms. They are often used to remove sputum, digestive tract bleeding, and organ or tissue fluids from their source and excrete them from the body. Existing negative pressure drainage devices are dual-port structures, consisting of a sealed bottle with two ports at the top: one for connecting to a drainage tube and the other for connecting to a negative pressure source. The drainage bottle is also marked with a scale, allowing medical staff to accurately understand the patient's drainage volume and provide accurate information for treatment.

[0003] Existing negative pressure drainage devices are prone to tipping over during use, causing drainage fluid to be sucked back into the negative pressure source, damaging or contaminating the negative pressure source and causing contamination of the negative pressure system. For this reason, existing negative pressure suction devices with publication numbers CN221490895U and CN217236924U are equipped with an anti-backflow mechanism at their outlets to prevent excessive backflow of accumulated fluid into the ward negative pressure equipment. However, such anti-backflow devices only have an anti-backflow structure at the outlet. The negative pressure suction barrel as a whole is very easy to tip over during use due to its complex and heavy barrel cover. After tipping over, not only is it easy for the accumulated fluid inside to be sucked back, but the connectors connected to the barrel cover are also easily torn or detached, causing equipment interruption and leakage of the suction fluid in the pipeline, causing contamination. Patent publication number CN221490895U discloses a hook on the side of the drainage bucket for fixation, but it must have a fixed hook position to match and fix it, and the hook position is fixed and cannot be adjusted according to actual environmental conditions, making it very inflexible to use.
