Description

A portable negative pressure suction device

technical field

The invention relates to a medical device, in particular to a portable negative pressure suction device.

Background technique

The thoracic cavity of the human body is a negative pressure cavity. The thoracic pressure of normal people is generally 6-10 centimeters of water column lower than the atmospheric pressure, so that the lungs are easy to open when people inhale, and they can instinctively contract to breathe. In clinical practice, for patients undergoing thoracic surgery and chest trauma treatment, since the negative pressure in the chest cavity disappears after the chest cavity is opened and sutured, it is necessary to discharge the blood, fluid and part of the air in the chest cavity to restore the pressure in the chest cavity to the original atmospheric pressure. status, or for patients treated for non-thoracic surgery and chest trauma, but according to the clinical treatment, the gas or liquid in the chest cavity must be discharged from the body, etc. At this time, a drainage system must be used to drain the gas in the chest cavity through a drainage tube. Or the fluid is drained into the drainage bottle.

In use, usually the suction port of the drainage bottle is directly connected to the central negative pressure system in the ward to perform negative pressure drainage on the patient, but this leads to the connection between the drainage bottle and the central negative pressure system, which is inconvenient to use when the patient moves, and is easy to increase Large nursing staff workload.
