Medical device for gas instillation in a surgical cavity.
Nitrogen contained in air should enter in a surgical cavity and produce an embolism after a surgical procedure.
To avoid this risk, CO2 is usually instilled into the cavity during a surgery. Because of the CO2 density, it has the capacity to move nitrogen outside the cavity. However, air turbulences are produced during surgeries, causing the nitrogen entered into the cavity.
To use a laminar flow during instillation, reduce the nitrogen entry and the embolism probability.
Most of the available devices in the market for gas instillation using a laminar flow must be suture to the patient. These devices usually obstruct the surgery.
To solve these problems, a researcher from the Andalusian Public Health System has developed a medical device to be installed inside the dead space of the surgical cavity. The device does not need to be attached to the patient, and produces a laminar flow inside the cavity.
Gas instillation with a laminar flow from inside surgical cavity.
It is not necessary to attach the device into the patient.
The device does not obstruct the surgery.
The connection between the device and the gas source is very easy.
