Needle thoracostomy device and method of use
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.

The needle thoracostomy device of claim 4 , wherein the needle is removable from the needle assembly through the first port and wherein the venting valve is biased toward the draining position such that the venting valve automatically rotates to the draining position upon removal of the needle from the first port.
6 . The needle thoracostomy device of claim 1 , wherein the base is configured to attach to a body of a patient, wherein when in the deployed position, the needle assembly extends into the patient, and wherein the needle is configured to automatically detach from the needle assembly when the needle enters a pleural cavity of the patient.
7 . The needle thoracostomy device of claim 1 , wherein, when the needle thoracostomy device moves from the raised position to the deployed position, the needle thoracostomy device is configured to maintain the needle assembly at a constant angle relative to the base.
8 . 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 the base is configured to attach to a body of a patient, wherein when in the deployed position, the needle assembly extends into the patient, and wherein the needle is configured to automatically detach from the needle assembly when the needle enters a pleural cavity of the patient.
9 . The needle thoracostomy device of claim 8 , further comprising a venting system configured to automatically fluidly couple with the catheter upon removal of the needle from the needle assembly.
10 . The needle thoracostomy device of claim 8 , further comprising a venting system having an outlet and a primary valve configured to drain fluid from the catheter to the outlet and restrict fluid flow from the outlet to the catheter.
11 . The needle thoracostomy device of claim 8 , further comprising a venting valve positioned adjacent the second end of the lever, the venting valve having a first port and a second port, wherein the venting valve is configured to rotate between a needle position in which the first port is aligned with the catheter and a draining position in which the second port is aligned with the catheter, wherein the venting valve fluidly couples the catheter to a venting system when in the draining position.
12 . The needle thoracostomy device of claim 11 , wherein the needle is removable from the needle assembly through the first port and wherein the venting valve is biased toward the draining position such that the venting valve automatically rotates to the draining position upon removal of the needle from the first port.
13 . The needle thoracostomy device of claim 8 , wherein, when the needle thoracostomy device moves from the raised position to the deployed position, the needle thoracostomy device is configured to maintain the needle assembly at a constant angle relative to the base.
14 . 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.
15 . The needle thoracostomy device of claim 14 , further comprising a venting system configured to automatically fluidly couple with the catheter upon removal of the needle from the needle assembly.
16 . The needle thoracostomy device of claim 14 , further comprising a venting system having an outlet and a primary valve configured to drain fluid from the catheter to the outlet and restrict fluid flow from the outlet to the catheter.
