US 12,642,893 B2 · Needle thoracostomy device and method of use

Abstract

A needle thoracostomy device with a venting device, a deployment device, and a positioning device. The venting device is configured to vent a pleural cavity of a patient. The deployment device is removably attached to the venting device and is configured to perform a needle thoracostomy to attach the venting device to the patient. The deployment device has a release mechanism which, when moved to a released position, allows the deployment device to be separated and lifted away from the venting device. The positioning device is configured to removably engage with at least one of the deployment device and the venting device to correctly position the deployment device and the venting device on the patient for the needle thoracostomy. The positioning device may position the deployment device and the venting device based on anatomical landmarks.

Dependent claims

A needle thoracostomy device, comprising:

a base having a first end and a second end;
a lever having a first end and a second end, wherein the first end of the lever is hingedly coupled to the second end of the base;
and
a needle assembly hingedly coupled to the second end of the lever and having a needle and a catheter, wherein the needle thoracostomy device is moveable between a stored position in which the lever and the needle assembly are adjacent the base, a raised position in which the lever is positioned at an oblique angle with respect to the base and the needle assembly extends between the lever and the base, and a deployed position in which the lever is adjacent the base and the needle assembly extends below the base;
wherein a hinge joining the lever to the base is configured to allow rotation and linear motion of the lever with respect to the base but constrain both the rotation and the linear motion such that the needle assembly moves along an axis of the needle as the needle thoracostomy device moves from the raised position to the deployed position.
