Surgical drain apparatus and method
First Claim
1. A surgical drain comprising:
- A. an elongated conduit portion having an outlet end and a marquise-shaped transverse cross-section, the conduit portion being adapted for transversing a wound with the major transverse axis of the marquise shape aligned with the wound so that the wound edges may conform to the marquise-shaped conduit portion and create a seal around the entire transverse perimeter of said conduit portion;
B. an elongated fluid intake portion connected to the end of said conduit portion opposite said outlet end and being adapted to be positioned within a patient'"'"'s body through the wound;
C. a fluid flow passage extending longitudinally through said conduit portion and said fluid intake portion of the drain, the fluid flow passage being adapted for enabling fluid to flow through said fluid intake portion and said conduit portion and out said outlet end of said conduit portion; and
D. at least one fluid intake opening in said fluid intake portion of the drain for enabling fluid to flow into said fluid flow passage.

Abstract
A surgical drain system includes an elongated drain member having a conduit portion connected to a fluid intake portion with a fluid flow passage extending continuously through both portions and with at least one fluid intake opening in the fluid intake portion. The conduit portion of the drain member has generally a marquise-shaped transverse cross-section, whereas the fluid intake portion has a similar cross-sectional shape but absent the pointed end portions of the marquise shape. In use, the drain member may be positioned with the fluid intake portion within the wound in a desired position and with the conduit portion traversing the wound, and the wound edges may easily be made to conform to the marquise shape of the conduit portion to form a substantial seal. The drain member also preferably includes a one-way valve connected to the conduit portion for preventing fluid from flowing into the wound through the drain member. The drain system may also include a fluid receptacle adapted to be sealably connected to the drain member for receiving fluid drained from the wound, and the receptacle may be adapted to provide a suction to the drain member.

15. A surgical drain system comprising:
-
A. an elongated surgical drain member having a conduit portion and a fluid intake portion connected together and also having a fluid flow passage extending longitudinally through both said conduit portion and said fluid intake portion, said conduit portion having a marquise-shaped transverse cross-section and said fluid intake portion having a similar marquise-shaped transverse cross-section but with the pointed end portions of the marquise shape being removed and also having at least one fluid intake opening through which fluid may flow into said fluid flow passage extending through said fluid intake portion; and B. a fluid receptacle having a fluid collection reservoir and connector means for sealably connecting with said conduit portion of the drain member so that fluid may flow from said fluid flow passage of the drain member into said fluid collection reservoir, whereby the drain member may be positioned for draining fluid through a suitable drain wound with said fluid intake portion within a wound, said conduit portion traversing the wound, and with the wound edges pressed against said conduit portion of the drain member so as to form a seal between the drain member and the wound, and whereby fluid may drain from the wound through said fluid flow passage of the drain member and into said fluid collection reservoir without substantial leakage between the drain member and the wound edge. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method of draining fluid that may develop within a surgical wound, said method comprising the steps of:
-
A. providing an elongated surgical drain member having a conduit portion and a fluid intake portion with a fluid flow passage extending longitudinally through both said conduit portion and said fluid intake portion, said conduit portion having a marquise-shaped transverse cross-section and including an outlet end, and said fluid intake portion having a generally marquise-shaped transverse cross-section but with the lateral pointed edges of the marquise shape being removed and also having at least one lateral opening through which fluid may flow into said fluid flow passage extending through said fluid intake portion; B. positioning the drain member with said fluid intake portion within a wound in the desired position for collecting fluid, and with said conduit portion traversing the wound, the major transverse axis of the conduit portion being aligned generally with an incision for said wound; C. applying at least one subcutaneous continuous stitch through subcutaneous tissue with the stitch material looping around said conduit portion of the drain member traversing the wound so that said subcutaneous stitch pulls the opposing sides of the incision against said marquise-shaped conduit portion of the drain member to substantially seal against said conduit portion; D. applying interrupted stitches along the wound on both sides of the drain member so as to further draw the wound edges against the drain member; and E. sealably connecting a suitable fluid receptacle to the outlet end of said drain member conduit portion so that the receptacle may receive fluid drained from the wound through the drain member, whereby fluid may drain from within the wound into said fluid intake portion of the drain member and then through said conduit portion of the drain member out of a patient'"'"'s body and into said drained fluid receptacle. - View Dependent Claims (28)
