Abstract
Abstract A container for the collection of body fluids such as urine, has a semirigid tubular frame disposed within a flexible bag. The frame serves first as a supporting structure with its crossbar extending across the top of the bag and legs extending down the sides, thus preventing the bag from being bent across either vertical or horizontal axis. Secondly, the frame serves as a fluid conduit from a central inlet to the bag''s main chamber. The lower part of each leg is cut away leaving an open channel to avoid any clogging of the fluid as it is discharged from the conduit into the main chamber.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
237 words
A body fluid drainage device for connection to the outlet end of a drainage tube such as a catheter, the device in its upright position, comprising: a. a closed container formed of thin, flexible, waterimpermeable plastic sheet material defining walls and a main chamber between the sheets, and upper and lower sections. b. a semirigid frame formed of (i) a laterally extending tubular crossbar having a conduit therethrough, (ii) at least two tubular legs spaced apart and extending generally downward from the crossbar, each leg having an internal passage connected to the conduit of the bar, and (iii) an inlet means having an upper tubular part with one end connectable to said outlet end of a drainage tube and a remote drip end, and a drip chamber defining an enclosure about an air space, this chamber having its inlet connected to said upper tubular part and its outlet connected to said conduit, with the drop end extending down into the drip chamber, and the air space thus separating said drip end and the conduit, the frame being secured inside the container with said inlet means extending out of the upper section of the container, the crossbar and legs preventing bending of the container, the crossbar and legs preventing bending of the container across these members, and c. valve means connected to the outlet aperture of the container for controlling discharge of accumulated fluid at the lower section.

A body fluid drainage device for connection to the outlet end of a drainage tube such as a catheter, the device in its upright position, comprising: a. a closed container formed of thin, flexible, waterimpermeable plastic sheet material defining walls and a main chamber between the sheets, and upper and lower sections. b. a semirigid frame formed of (i) a laterally extending tubular crossbar having a conduit therethrough, (ii) at least two tubular legs spaced apart and extending generally downward from the crossbar, each leg having an internal passage connected to the conduit of the bar, and (iii) an inlet means having an upper tubular part with one end connectable to said outlet end of a drainage tube and a remote drip end, and a drip chamber defining an enclosure about an air space, this chamber having its inlet connected to said upper tubular part and its outlet connected to said conduit, with the drop end extending down into the drip chamber, and the air space thus separating said drip end and the conduit, the frame being secured inside the container with said inlet means extending out of the upper section of the container, the crossbar and legs preventing bending of the container, the crossbar and legs preventing bending of the container across these members, and c. valve means connected to the outlet aperture of the container for controlling discharge of accumulated fluid at the lower section.
Claim 3
Dependent Claim
19 words
A device as defined in claim 1 wherein the frane''s crossbar, legs and inlet means comprise a unitary subassembly.
Claim 4
Dependent Claim
25 words
A device as defined claim 2 wherein said subassembly comprises two mating shells, each part/defining one-half of the tubular frame cut by an axial plane.
Claim 5
Dependent Claim
23 words
A device as defined in claim 1 wherein the lower part of each leg has at least one aperture in the sidewall thereof.
Claim 6
Dependent Claim
34 words
A device in defined in claim 4 wherein the lower part of each leg defines in a cross section a U-shaped channel, the aperture in the side of the leg thus being a slot.
Claim 7
Dependent Claim
44 words
A device as defined in claim 2 wherein the container is formed of two sheets heat-sealed together along their top, bottom, and side edges, with the upper part of the inleT mean extending between adjacent top edges of the two sheets and sealed therebetween.
Claim 8
Dependent Claim
41 words
A device as defined in claim 6 wherein the frame''s crossbar is spaced from the top edge of the container, with a margin of sheet material between said edge and the bar, the device further comprising means for stiffening said margin.
Claim 9
Dependent Claim
27 words
A device as defined in claim 7 wherein said means for stiffening comprises semirigid board material disposed between said marginal parts of said sheets and heat-sealed therebetween.
Claim 10
Dependent Claim
59 words
A device as defined in claim 1 including a breather aperture in an upper section of one of the sheets interconnecting the main chamber and the atmosphere, the device further comprising a filter covering the breather aperture, the filter formed of microporous material permitting passage of air and other gas while substantially barring any passage of liquid and bacteria.
Claim 11
Dependent Claim
29 words
A device as defined in claim 9 wherein said container sheets are flexible polyvinylchloride, the frame is rigid polyvinylchloride, and the filter is Teflon-coated fiber glass having 4-micron pores.
Claim 12
Dependent Claim
73 words
A device as defined in claim 1, wherein the container''s sheets form (i) generally rectangular front and rear walls and a bottom, and (ii) generally triangular shaped end walls, with one point and an opposite side or each triangle at the container''s top and bottom respectively, and wherein the legs of the frame extend downward to the container''s bottom, but are laterally spaced from the corner intersections of the side and bottom parts.
Claim 13
Dependent Claim
60 words
A device as defined in claim 11 further comprising semirigid strips secured in generally vertical orientation on the front and rear walls, the strips having lower ends laterally spaced form the bottom ends of the frame legs, where by the container when at least partially filled with fluid and disposed on a generally horizontal surface is stabilized to remain upright.
