Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a combination urine meter and urinary drainage bag.

2. Description of the Prior Art

Prior to this invention urine meters and urinary drainage bags were separate devices. An example of a urine meter is shown in U.S. Pat. No. Re. 30,607. An example of a urinary drainage bag shown in U.S. Pat. No. 4,363,406. The principal object of this invention is to provide a single unit which serves both as a urine meter and also as a urinary drainage bag. A further object of the present invention is to provide a unit which is of relatively simple construction and accordingly is relatively inexpensive to manufacture.

SUMMARY OF THE INVENTION

The invention in its simplest form is comprised of a sealed container having an inlet through which urine can flow into the interior of the container. A barrier means is provided for dividing the interior of the container into a urine metering compartment and a urine collection compartment. A hanger means is provided on the container for hanging the container in a meter operating position. A second hanger means is provided for hanging the container in a drainage operating position. A passageway means is provided which interconnects the urine metering compartment with the urine collection compartment. The inlet on the container is positioned so that urine flowing therethrough when the container is in its meter operating position will flow into and be collected in the urine metering compartment. The barrier means is constructed so that when the container is rotated from its metering operating position, urine will flow from the urine metering compartment through the passageway means and then into the urine collection compartment. When the unit is hung in its urine drainage position urine will flow directly from the inlet through the passageway and into the urine collection compartment.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 3, in the preferred embodiment of the present invention the combination urine meter and urinary drainage bag 8 is comprised of a front sheet 10 and a back sheet 12 of fluid impervious flexible material such as polyvinyl cloride. The front sheet 10 and back sheet 12 are sealed along their marginal edge 14 to form a sealed flexible bag container.

The unit 8 is provided with a drainage valve 16 in the lower right-hand corner thereof (as viewed in FIG. 1) mounted on a tube 18 inserted and sealed between front and back sheets 10 and 12 as shown in FIG. 4.

The urine meter 8 is provided with an inlet assembly 22 of any suitable design through which fluid from tube 20 flows into the unit 8. Inlet assembly 22 is located at the upper left-hand portion of the meter as viewed in FIG. 1.

The unit is provided with a pair of stabilizer bars 24, 26 mounted along the vertical and horizontal edges of the unit as viewed in FIG. 1. Bar 24 is captured between front and back sheets 10 and 12 as shown in FIG. 3. Bar 26 is also captured between sheets 10 and 12 along the top edge of the unit in a manner like that shown in FIG. 3.

The unit 8 is provided with a pair of hanging tabs 28 and 30 located on the left-hand and top edges of the unit as shown in FIG. 1. Hanging tabs 28 and 30 have openings 32 therein for purposes of connecting the tabs to a hanging hook or other similar part. As shown in FIG. 3 seal lines 34 and 14 serve to capture bar 24 and also serve to form the outer edge of hinge tab 28. The construction of the top hanging tab 30 is the same as tab 28.

The sealed internal portion of the unit 8 is divided into two compartments 38 and 40 by a seal line 42 as best shown in FIG. 3. The smaller compartment 38 serves as a metering compartment and the larger compartment 40 serves as a collection compartment as will be described in detail hereinafter.

In the preferred embodiment seal line 42 as well as seal lines 14, 34 and 36 are made by an electronic welding process.

As best shown in FIG. 1, seal line 42 extends from the left end of seal line 14 at the bottom of the unit and then angles upwardly therefrom to a point 43 spaced a short distance from seal line 14 at the top edge of the unit. The seal line 42 makes a gentle curve at point 43 and then angles downwardly to seal line 14 at the bottom edge of the unit. The gentle curve at point 43 prevents the creation of a stress point in this area.

Thus it is seen that with the unit in the FIG. 1 position, seal line 42 serves as a barrier between compartments 38 and 40 leaving a relatively small interconnecting passageway 45 between the compartments which passageway is defined by the space between point 43 and the seal line 14 along the top of the unit.

The front sheet 10 of the unit is provided with volumetric scales 45, 46 and 48 the function of which will be explained hereinafter.

Referring to FIGS. 5 and 6, in the second embodiment of the present invention the combination urine meter and urinary drainage bag 50 is comprised of a front sheet 52 and a back sheet 54 of fluid impervious flexible material such as polyvinyl cloride. The front sheet 52 and the back sheet 54 are sealed along their marginal edge 56 to form a sealed flexible bag container.

The unit 50 is provided with a drainage valve 58 in the lower right-hand corner thereof (as viewed in FIG. 5) mounted on a tube 60 inserted and sealed between front and back sheets 52 and 54.

The urine meter 50 is provided with an inlet drip tube assembly 62 through which fluid from tube 64 flows into the unit 50. Inlet assembly 62 is located at the upper left-hand portion of the meter as viewed in FIG. 5. Tube 64 enters the meter at an angle of about 45 degrees with respect to the horizontal. As shown in FIG. 6, tube 64 is inserted in a drip tube housing 66 with the end of the tube spaced from the housing walls. The distance between the drip site (A) on the tube 64 and the point (B) at which drops hit the inlet surface must be great enought to prevent bridging of the liquid between the two points. Such distance shall be at least 3 mm.

The unit is provided with a pair of stabilizer bars 68, 70 mounted along the vertical and horizontal edges of the unit as viewed in FIG. 5. Bar 68 is captured between front and back sheets 52 and 54 as shown in FIG. 7. Bar 70 is also captured between sheets 52 and 54 along the top edge of the unit in a manner like that shown in FIG. 7. Bars 68 and 70 serve two functions i.e. to insure that the unit hangs properly in both hanging positions and to facilitate accurate reading of the volumetric scales.

The unit 50 is provided with a pair of hanging tabs 72 and 74 located on the left-hand and top edges of the unit as shown in FIG. 5. Hanging tabs 72 and 74 have openings 76 therein for purposes of connecting the tabs to a hanging hook or other similar part. As shown in FIG. 7, seal lines 73 and 56 serve to capture bar 68. The construction of the top hanging tab 74 is the same as tab 72.

As shown in FIG. 7, the sealed internal portion of the unit 50 is divided into two compartments 78 and 80 by a seal line 82. The smaller compartment 78 serves as a metering compartment and the larger compartment 80 serves as a collection compartment.

As best shown in FIG. 5, seal line 82 extends from the left end of seal line 56 at the bottom of the unit and then angles upwardly therefrom to a point 84 spaced a short distance from seal line 56 at the top edge of the unit. The seal line 82 makes a gentle curve at point 84 and then angles downwardly to seal line 56 at the bottom edge of the unit. The gentle curve at point 84 prevents the creation of a stress point in this area.

Thus it is seen that with the unit in the FIG. 5 position, seal line 82 serves as a barrier between compartments 78 and 80 leaving a relatively small interconnecting passageway 86 between the compartments which passageway is defined by the space between point 84 and the seal line 56 along the top of the unit.

The front sheet 10 of the unit is provided with volumetric scales 88, 90 and 92 the function of which will be explained hereinafter. A vent assembly 94 is mounted on the upper portion of front sheet 52. Vent assembly 94 is mounted in the upper left hand corner above drip tube inlet assembly 62 so that incoming liquid will not flow past the vent assembly in either of the two hanging positions of unit 50.

OPERATION

In normal use as a urine meter the unit is hung in the FIG. 1 position by means of hanging tab 30. In such position urine from the patient flowing through tube 22 into the unit will collect in compartment 38 to the left of seal line 42.

The rate of flow can be determined by monitoring the flow using scale 44 relative to a predetermined period of time. When it is desired to obtain a subsequent reading the urine which has collected in compartment 38 can be emptied into collection compartment 40 by simply rotating it approximately 90 degrees to a position substantially like that shown in FIG. 2. In such position urine will flow from compartment 38 to compartment 40 through the passageway 45 defined by the space between the seal line point 43 and the seal line 14 along the top of the unit. After compartment 38 has been emptied the unit is returned to its original FIG. 1 hanging position and a second flow rate can be determined. Scale 46 indicates the volume of urine which collects in compartment 40. Compartment 40 can be drained by means of valve 16.

After a period wherein the rate of urine flow from a patient is monitored by the procedure described above, such monitoring is often no longer necessary. At such time, however, it is often necessary to simply collect urine flowing from the patient. In such an event the conventional practice is to replace the urine metering device with a urinary drainage bag in which event the urine meter is disposed of. Such sequential treatment of the patient thus required two separate devices namely a urine meter and a urinary drainage bag.

The unit 8 described herein is designed not only to function as a urine meter as described above, but in addition the unit 8 is capable of also functioning as a urinary drainage bag. Thus, for example, when the metering function is no longer required the unit 8 can be converted to a drainage bag by simply repositioning the unit from its FIG. 1 hanging position to the hanging position shown in FIG. 2. In such FIG. 2 position hanging tab 28 is put into use.

In the FIG. 2 position urine flowing from the patient through tube 22 will enter the unit in the upper right hand corner thereof. Such flow will pass directly through the passageway 45 and be collected in the bottom of large collection compartment 40. Scale 48 serves to indicate the volume of urine collected in compartment 40 when the unit is used as a urinary drainage bag.

The operation of the embodiment shown in FIGS. 5, 6 and 7 is the same as that described above for the embodiment shown in FIGS. 1, 2, 3 and 4.
