Abstract
Abstract A medical drainage apparatus is provided for draining surgical wounds or internal organs or cavities. The apparatus comprises a pair of flexible pleated tubes which are adapted to be connected to a pair of drainage tubes which extend from the body, a relatively rigid Y connector which is connected to the flexible tubes, and a relatively rigid bridge which extends over the flexible tubes and which is adapted to be attached to the body and to hold the Y connector.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
139 words
A medical drainage apparatus for draining fluid from the body comprising: a tube having a first portion which is adapted to be connected to an area of the body which is to be drained, an intermediate, pleated flexible portion, and a third portion, the pleated flexible portion being able to accommodate relative movement between the first and third portions by flexing, elongation, and compression; and a relatively rigid bridge adapted to be secured to the body for holding the third portion of the tube relative to the body, the bridge having a pair of base portions adapted to be attached to the body and an intermediate portion between the base portion which extends over the tube, the intermediate portion of the bridge including a tabe which extend toward the third portion of the tube and holds the third portion.
Claim 2
Dependent Claim

A medical drainage apparatus for draining fluid from the body comprising: a tube having a first portion which is adapted to be connected to an area of the body which is to be drained, an intermediate, pleated flexible portion, and a third portion, the pleated flexible portion being able to accommodate relative movement between the first and third portions by flexing, elongation, and compression; and a relatively rigid bridge adapted to be secured to the body for holding the third portion of the tube relative to the body, the bridge having a pair of base portions adapted to be attached to the body and an intermediate portion between the base portion which extends over the tube, the intermediate portion of the bridge including a tabe which extend toward the third portion of the tube and holds the third portion.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 in which the tab includes an arcuate recess for engaging the third portion of the tube.
Claim 4
Dependent Claim
37 words
The apparatus of claim 1 in which the tab includes an attaching portion which extends generally parallel to the body whereby the third portion of the tube can be taped to the attached portion of the tab.
Claim 5
Dependent Claim
39 words
The apparatus of claim 1 in which each of the base portions is generally planar and has a central opening therein, whereby adhesive tape can be applied over each base portion to contact the body through the central opening.
Claim 6
Dependent Claim
20 words
The apparatus of claim 1 in which each of the base portions comprises a plurality of laterally extending spaced-apart feet.
Claim 7
Dependent Claim
158 words
A medical drainage apparatus for draining fluid from the body comprising: a pair of flexible pleated tubes adapted to be connected to an area of the body which is to be drained, the flexible pleated tubes being able to accommodate relative movement between the Y connector and the area of the body which is to be drained by flexing, elongation, and compression; a Y connector having a pair of ends connected to the pleated tubes and a third end for delivering fluid which flows through the pleated tubes; and a relatively rigid bridge adapted to be secured to the body for holding the Y connector relative to the body, the bridge having a pair of base portions adapted to be attached to the body and an intermediate portion between the base portion which extends over the pleated tubes, an intermediate portion of the bridge including a tab which extends toward the Y connector and holds the Y connector.
Claim 8
Dependent Claim
158 words
A medical drainage apparatus for draining fluid from the body comprising: a pair of flexible pleated tubes adapted to be connected to an area of the body which is to be drained, the flexible pleated tubes being able to accommodate relative movement between the Y connector and the area of the body which is to be drained by flexing, elongation, and compression; a Y connector having a pair of ends connected to the pleated tubes and a third end for delivering fluid which flows through the pleated tubes; and a relatively rigid bridge adapted to be secured to the body for holding the Y connector relative to the body, the bridge having a pair of base portions adapted to be attached to the body and an intermediate portion between the base portion which extends over the pleated tubes, an intermediate portion of the bridge including a tab which extends toward the Y connector and holds the Y connector.
Claim 9
Dependent Claim
