Abstract

A drainage tubing for wounds, or body cavities, is described. The tubing is placed and retained in the wound site in an improved manner by means of an inflatable balloon positioned in the intact, healthy tissue adjacent the patient'"'"'s skin, or in the body cavity adjacent a wall thereof. The drainage tubing may also have a second, collapsible bulb portion for aseptic back-flushing of the placement site while the tubing lumen is sealed from the exterior. The specific construction enables a technician to insert the tubing when used in a wound site either from within or without the placement site using an awl to penetrate the exterior tissue adjacent the site.

Claims

1. In a drainage device for wounds, body cavities, and the like, said device comprising an elongated tubular drainage member having a central lumen, and a plurality of drainage ports defined along a first portion of the length of said tubular member and through said tubular member for fluid communication between said lumen and the exterior of said tubular member, the improvement comprising, in combination, an elastomeric retention balloon carried by a second portion of said tubular member located to one side of one end of the first portion, and adapted to be inflatable under the skin of a patient when said first portion is properly positioned in a wound, said tubular member also carrying means for inflating and deflating said retention balloon, a length of severable imperforate tubing extending from the end of said first portion and having a terminus adapted for screw connection to an awl, said imperforate length of tubing permitting selective connection to an awl without contamination of the drainage ports in said first portion, an enlarged-lumen portion in communication through the central lumen with the drainage ports and for use as a combination squeeze pump and storage portion for retention of a flushing solution therein, means for selectively sealing said enlarged-lumen portion so that squeezing said squeeze pump operates to back flush solution through the drainage ports, and the means for inflating and deflating the retention balloon being a second tube that is secured along its length to said tubular member and extends along said tubular member from said retention balloon toward said enlarged-lumen but terminating spaced from said enlarged-lumen.

2. The drainage device of claim 1 wherein the cross-section size of the second tube is smaller than that of the tubular member, the tubular member being separate from the enlarged-lumen, and each end of the tubular member permitting selective connection to an awl, thereby permitting the tubular member to be drawn by such an awl from either end through tissue into the drainage site.

3. The drainage device of claim 1 wherein the wall of the second tube is of a pierceable but self-sealing material capable of maintaining fluid pressure developed within the tubular means and the retention balloon.

4. The drainage device of claim 1 wherein the enlarged-lumen portion is formed integral with an end of the tubular member that is spaced from the second tube.

5. In a drainage device for wounds, body cavities and the like, said device comprising an elongated tubular drainage member having a central lumen, drainage means defined along a first portion of the length of said tubular member through the wall of said tubular member for fluid communication between said lumen and the exterior of said tubular member, the improvement comprising, in combination, an elastomeric retention balloon carried by a second portion of said tubular member adjacent one end of the first portion of said tubular member, an elongated second tubular means secured along its entire length to a portion of the length of the tubular member and extending from the retention balloon in a direction away from said first portion of the tubular member, the opposite ends of the tubular member extending respectively beyond the drainage means in the first perforate portion and the tubular means carrying portion, the cross-section size of the second tubular means being smaller than that of the tubular member, and each end of the tubular member permitting selective connection to an awl without contamination of either the drainage ports or damage to the tubular means, thereby permitting the tubular member, with second tubular means secured thereto, to be drawn by such an awl from either end through tissue into the drainage site.

6. The method of providing drainage from a wound site or the like in a patient which comprises:

inserting a tubular drainage member, having a plurality of lateral drainage ports defined along a first portion of said tubular drainage member, into the wound site in a position such that said drainage ports are in flow communication with said wound site,

using a pointed penetrating means that is removably secured to an end of said drainage member for passing a second portion of said tubular member through intact, healthy tissue so that one end of said tubular member communicates with the exterior,

positioning a balloon retention member carried by said second portion of the tubular member within the intact, healthy tissue adjacent the patient'"'"'s skin at the same time that the tubular drainage member is being positioned in the wound site; and

inflating the balloon member, to firmly retain the tubular member in the wound site, and to seal the area between said tubular member and said intact, healthy tissue.
