Medical drainage device with adjustable supporting strap

Claim 2

A medical drainage device comprising a container for receiving body fluid drainage from a patient, said container including fluid inlet means adapted for fluid communication with a source of body fluid drainage, an upper portion having two opposed sides with at least one groove in each of said opposed sides extending laterally inwardly from the outer periphery of said container, and a flexible strap, means for connecting opposite ends of said strap to said upper portion respectively adjacent said opposed sides, said strap connecting means being spaced from said grooves, said strap and each of said grooves being sized relative to each other to permit movement of selected portions of said strap into said grooves to provide a selected strap arrangement capable of supporting said container.

Claim 3

The device of claim 1 wherein each of said grooves includes a hole sized to receive said strap and an entrance slot extending from the hole to the periphery of said container adjacent said hole to allow insertion of said strap, side wall first, through said entrance slot and into said hole.

Claim 4

The device of claim 2 wherein each of said holes and said slots are sized slightly smaller in width than the width of said strap.

Claim 5

The device of claim 3 wherein each of said slots has a portion with a width smaller than the width of each of said holes.

Claim 6

The device of claim 4 wherein the length of said strap is greater than the maximum peripheral distance around said container.

Claim 7

The device of claim 5 wherein each of said opposed sides has another groove similar to said one groove.

Claim 8

The device of claim 1 wherein said container is of plastic material.

Claim 9

The device of claim 1 wherein said container comprises a lid closing the upper end thereof, a liquid seal chamber, and a body fluid collection chamber below said seal chamber, and fluid connection means adapted for connection with a body cavity extending through said lid and into said seal chamber, said seal chamber being in fluid communication with said collection chamber.

Claim 10

The device of claim 1 wherein said container is formed of substantially rigid plastic, and said strap is formed of a plastic which is more flexible than that of said container.

Claim 11

The device of claim 1 wherein said container has a lower end portion with a peripheral skirt extending below the bottom of said container, said skirt having a slot in said skirt at each side of said container for receiving said strap to permit said strap to extend along the bottom of said container substantially without extending below the bottom of said skirt.

Claim 12

The device of claim 10 wherein said strap is longer than the maximum periphery around said container and is formed of plastic.

Claim 13

The device of claim 11 wherein said strap is capable of being simultaneously disposed in each of said grooves and each of said skirt slots and having a portion extending above said upper portion of said container for supporting said container from a support above said container.

Claim 14

The device of claim 11 wherein said strap is sufficienhy long to support said container at the hip from a shoulder of an average sized adult person.

Claim 15

A medical drainage device comprising a container for receiving body fluid drainage from a patient, said container including fluid inlet means adapted for fluid communication with a source of body fluid drainage, an upper portion having a laterally outwardly extending flange at each of two opposite sides thereof, each of said flanges having at least one groove extending laterally inwardly from the outer periphery of the flange, and a flexible strap having opposite ends connected to said upper portion respectively adjacent said opposite sides and at points spaced from said grooves, said strap and each of said grooves being sized relative to each other to permit laterally inward movement of said strap, side wall first, into said grooves to provide selected strap arrangements capable of supporting said container in different ways, the width of said grooves being less than the width of said strap so that outward lateral movement of said strap in said groove is opposed by frictional engagement between the opposed side walls of said grooves and said strap.

Claim 16

A medical drainage device comprising a container for receiving body fluid drainage from a patient, said container including fluid inlet means adapted for fluid communication with a source of body fluid drainage, an upper portion having a laterally outwardly extending flange at each of two opposite sides thereof, each of said flanges having at least one groove extending laterally inwardly from the outer periphery of the flange, and a flexible strap having opposite ends connected to said upper portion respectively adjacent said opposite sides and at points spaced from said grooves, said strap and each of said grooves being sized relative to each other to permit laterally inward movement of said strap, side wall first, into said grooves to provide selected strap arrangements capable of supporting said container in different ways, the width of said grooves being less than the width of said strap so that outward lateral movement of said strap in said groove is opposed by frictional engagement between the opposed side walls of said grooves and said strap.

Claim 17

The device of claim 14 wherein said container has a lower end portion with a peripheral skirt extending below the bottom of said container, said skirt having a slot at each side of said container for receiving said strap to permit said strap to extend along the bottom of the container substantially without extending below the bottom of said skirt.

Claim 18

The device of claim 15 wherein each of said grooves includes a hole sized to receive said strap and an entrance slot extending from the hole to the periphery of the flange to allow insertion of said strap, side wall first, through the entrance slot and into the hole.

Claim 19

The device of claim 15 wherein the medical drainage device is a thoracic drainage device, said container includes a bottom wall closing the bottom end and a lid closing the upper end, tube means extending through said lid and into said container, said tube means having means externally of said container for connecting fluid coupling means thereto which is adapted for connection with the pleural cavity of a patient.

Claim 20

The device of claim 17 wherein said container comprises a liquid seal chamber, and a body fluid collection chamber below said seal chamber, and, said seal chamber being in fluid communication with said collection chamber.

Claim 21

The device of claim 17 wherein said container is formed of a relatively hard plastic material, said strap is formed of a relatively flexible plastic material, and the opposite ends of said strap are respectively connected to said flanges.

Claim 22

The device of claim 14 wherein said strap is circular in cross-section and is of plastic material.

Claim 23

The device of claim 14 wherein each of said grooves includes a hole sized to receive said strap and an entrance slot extending from the hole to the periphery of the flange to allow insertion of said strap, side wall first, through the entrance slot and into the hole.
