Negative Pressure Suction Liner
A negative pressure suction liner is a device that creates an area of lower air pressure within a container.negative pressure suction liner This area of lower air pressure forces out ambient air molecules that are attempting to move into the container, and draws in fresh clean air to replace those molecules. Negative pressure is often used in laboratory containers to prevent contamination. It is a process known as containment, which helps to ensure that hazardous materials or biological agents don’t escape the container and potentially affect the environment outside of the container.
In addition to preventing the spread of contaminants, negative pressure can also be useful for a variety of other applications. For example, a negative pressure suction liner can be used to prevent the loss of precious samples in laboratory experiments. In addition, negative pressure can be used to control the temperature of a workspace and limit the growth of microorganisms.
Negative pressure can also be helpful for a patient’s breathing. The negative pressure in the chest cavity can help to expand the lungs, which allows them to take in more oxygen. This increase in oxygen can improve a patient’s overall condition and can make them feel more energetic.
During the COVID-19 pandemic, many hospitals have been using a negative pressure isolation biohazard hood to minimize the risk of infection for healthcare workers performing aerosolizing procedures on patients with suspected or confirmed COVID-19 infections. Hospitals have traditionally used wall suction to create the negative pressure isolation environments, but this system has several limitations including immobility, single patient use, and weaker suction capabilities.
The Stryker Neptune(tm) is a high-powered suction system that can be adapted to create a negative pressure isolation biohazard
suction hood to reduce the potential for exposure to infectious materials. The Neptune can be transported to patient rooms and used in a hospital operating room to create negative pressure isolation hoods for multiple patients at once. This novel approach to creating negative pressure isolation hoods significantly reduces the need to transfer patients to scarcely available negative pressure rooms in the hospital.
Our results suggest that the 200 mmHg negative pressure applied during open system suction does not cause any clinically significant changes in pulse oximetry and HR values during and after suctioning. The study was limited to a small sample size and the results need to be verified by further comparative studies with different levels of negative pressure suction.
In addition to being able to transport the Neptune to patient rooms, the device is easy to set up and uses simple piping and tubing to connect to a hospital’s existing positive or negative pressure vacuum pump. The system can be easily re-adapted to create negative pressure suction for other uses, such as aspiration waste collection. This closed suction system includes a non-sterile disposable suction liner with pre-connected tubing and a pediatric MED-STOP fingertip control vacuum valve. The liner is made of low-memory flexible tubing that resists kinking. It also has a suction port to connect to a hospital’s existing negative pressure suction pump.
