Abstract:
1. A device for pneumothorax, tension pneumothorax, pleural effusion, or hemothorax, comprising: (a) a catheter comprising an outer surface having continuous longitudinal ribs extending outward from the surface to render the catheter kink resistant, a proximal opening and distal opening, said distal opening being capable of receiving gases and fluids from an interpleural space; (b) a rigid body comprising a flat discoid surface surrounding the lower port, and a dome intersecting the flat discoid surface, comprising a lower port on the discoid surface that is connected to and opens to the proximal opening of the catheter, a side port, and an upper port aligned with the lower port, said body having a width such that the body may be gripped with two fingers of an operator's hand, wherein the dome, discoid surface and catheter are portions of one molded piece of material and wherein the discoid surface comprises an outer ring extending outside the intersection of the dome and discoid surface, and wherein said outer ring comprises a plurality of fenestrations that allow the discoid surface to be sutured to the patient; (c) a one-way valve in communication with the side port of the body, said one-way valve configured to allow egress of gases and fluids from the side port and prevent ingress of gases to the side port; and (d) a removable stylet of approximately 18 gauge having a sharp point and a shaft that extends from the upper port, through the lower port, and through the catheter, the sharp point extending a distance past the distal opening of the catheter, wherein the stylet passes through the rigid body without passing through the one-way valve; (e) a hub disposed on the stylet and seated near the upper port, the hub having a hub annulus, wherein the body has a width and a height suitable such that the device may be gripped with two fingers of one hand on the body and another one or two fingers of the same hand on the hub to penetrate the sharp pointed instrument through a chest wall into the interpleural space, and the body has a width and a height suitable such that the hub annulus may be raised with the one or two fingers on the hub to remove the stylet while continuing to grip the body with two fingers of the same hand.
