Urine meter and drainage receptacles

Claim 2

A combination urine meter and drainage receptacle comprising: a liquid meter defined by a first container having at least one volume-calibrated chamber, said meter having an inlet opening through which liquid may be introduced to said chamber and an exit portal spaced from and located below said opening; a receptacle defined by a second container having a receiving portal located in a position above the bottom of said container and near the top thereof; means for detachably attaching said meter and receptacle together in a position such that the receiving portal of the receptacle is located above the exit portal of the meter and below the inlet opening thereof; and a conduit extending from said exit portal to said receiving portal to provide a path of liquid flow from the interior of said meter to the interior of said receptacle whereby, when said meter is filled to the level corresponding to the level of said receiving portal when the meter and receptacle are in said position, additional liquid entering said meter causes liquid to flow from said meter into said receptacle through said portals and conduit.

Claim 3

The combination urine meter and drainage receptacle of claim 1 wherein said meter includes a closable sampling port which may be opened to permit liquid to be drained out of the combination from the interior of said meter.

Claim 4

The combination of claim 2 wherein said receptacle includes a closable drainage port which may be opened to permit liquid to be drained out of the combination from the interior of said receptacle.

Claim 5

The combination urine meter and drainage receptacle of claim 1 wherein said first container defining the meter includes a vent opening through one of its walls and a bacterial filter connected to said vent, said filter being pervious to air and positioned to filter air entering said meter through said vent.

Claim 6

The combination of claim 4 wherein said filter is impervious to body fluids and is positioned to prevent body fluids from leaving said meter through said vent.

Claim 7

The combination of claim 4 wherein said vent is located in the upper portion of said meter.

Claim 8

The combination of claim 4 wherein said second container defining the receptacle also includes a vent opening through one of its walls and a bacterial filter connected to said vent, said filter being pervious to air and positioned to filter air entering said receptacle through said vent.

Claim 9

The combination of claim 1 wherein said first container defining said meter comprises an upper section and a lower section, said lower section being of smaller volume per unit of height than said upper section, and being calibrated to facilitate more accurate measurement of small changes in volume of liquid in said lower section than in said upper section.

Claim 10

The combination of claim 8 wherein: said receptacle comprises a front and a back sheet of flexible, fluid impervious material, said front and back sheets being sealed together along their marginal edge portions to form said second container, said front and back sheets also being sealed together along portions thereof intermediate the marginal edges to form an indentation in the receptacle when containing liquid; and wherein said meter is positioned adjacent the receptacle to overlie the indentation when the receptacle contains liquid.

Claim 11

A combination urine meter and drainage receptacle comprising: a urine meter defined by a first container having a front wall, a back wall, a top, a bottom, and side walls of rigid, fluid-impervious material, said first container having an upper section and a lower section of smaller volume per unit of height than said upper section, said front wall having thereon a scale to indicate the volume of liquid contained in said meter, said first container also having an inlet opening in said top through which fluid may be introduced into said meter, a closable sampling port at said bottom which may be opened to drain liquid from the interior of said meter, a vent opening into the meter through said top with a bacteriological filter connected to said vent, said filter being pervious to air and impervious to body fluids and positioned to filter air entering said meter through said vent, and an exit portal located in a portion of a side wall along said lower section; a receptacle comprising front and back panels of flexible, fluid-impervious sheet material sealed together along their marginal edge portions to define a bag-like second container having a receiving portal in the front panel, a vent opening into the receptacle through said front panel with a bacteriological filter connected to said vent, said filter being pervious to air and impervious to body fluids and positioned to filter air entering said receptacle through said vent and prevent body fluids from leaving the receptacle through said vent, a scale on said front panel adapted to indicate the volume of liquid contained in said receptacle, a closable drainage port located near the bottom edge of said second container through which liquid may be drained from said combination; a hollow conduit extending from said exit portal, where it is connected to said meter by a fluid-tight connection, to said receiving portal, where it is connected to said receptacle by another fluid-tight connection, whereby the interior of said meter communicates through said exit portal with the interior of said receptacle through said receiving portal By means of said conduit, so that fluid may pass from the interior of the meter into the interior of said receptacle through said conduit; and means for maintaining said meter and said receptacle in predetermined positions relative to each other such that, when so maintained, said receiving portal is above said exit portal.

Claim 12

A combination urine meter and drainage receptacle comprising: a urine meter defined by a first container having a front wall, a back wall, a top, a bottom, and side walls of rigid, fluid-impervious material, said first container having an upper section and a lower section of smaller volume per unit of height than said upper section, said front wall having thereon a scale to indicate the volume of liquid contained in said meter, said first container also having an inlet opening in said top through which fluid may be introduced into said meter, a closable sampling port at said bottom which may be opened to drain liquid from the interior of said meter, a vent opening into the meter through said top with a bacteriological filter connected to said vent, said filter being pervious to air and impervious to body fluids and positioned to filter air entering said meter through said vent, and an exit portal located in a portion of a side wall along said lower section; a receptacle comprising front and back panels of flexible, fluid-impervious sheet material sealed together along their marginal edge portions to define a bag-like second container having a receiving portal in the front panel, a vent opening into the receptacle through said front panel with a bacteriological filter connected to said vent, said filter being pervious to air and impervious to body fluids and positioned to filter air entering said receptacle through said vent and prevent body fluids from leaving the receptacle through said vent, a scale on said front panel adapted to indicate the volume of liquid contained in said receptacle, a closable drainage port located near the bottom edge of said second container through which liquid may be drained from said combination; a hollow conduit extending from said exit portal, where it is connected to said meter by a fluid-tight connection, to said receiving portal, where it is connected to said receptacle by another fluid-tight connection, whereby the interior of said meter communicates through said exit portal with the interior of said receptacle through said receiving portal By means of said conduit, so that fluid may pass from the interior of the meter into the interior of said receptacle through said conduit; and means for maintaining said meter and said receptacle in predetermined positions relative to each other such that, when so maintained, said receiving portal is above said exit portal.

Claim 13

The combination of claim 10 wherein said closable drainage port located near the bottom edge of said second container comprises a hollow tube opening out of said receptacle and being closable by a removable clamping means.

Claim 14

The combination of claim 11 including a side pocket on the front panel of said receptacle wherein said hollow tube may be stored with its opening directed upward.

Claim 15

The combination of claim 10 including means attached to said receptacle for hanging said combination urine meter and drainage receptacle from a supporting structure.
