specific embodiment

As shown in the accompanying drawings and described in detail below, one aspect of the present invention relates to a self-standing disposable urine collection bag that is easy to measure urine volume, facilitates handling and disposal of urine, and is inexpensive to manufacture. Specifically, to provide a bag with a complete, repeatable and continuously deployable interior region, which allows correct and precise reading of the volume of urine contained within the bag, allowing for quick, safe, and easy direct use of the bag Store and dispose of urine.

In one embodiment, the expansion of the bag is due to the pressure exerted on the inside of the bag. See also Fig. 1, 2 and 3, disposable urine bag 1 comprises the front side panel 3 and the back side panel 5 that are made by soft plastics, and the bottom sheet 7 that folds inwardly recesses, and these sheet parts can pass through various One of the common ways to connect them together. It is understood that various methods of joining the pieces and fittings together are applicable and suitable for use in the embodiments described below, including, but not limited to, heat bonding, heat sealing, hot melt bonding, or are other suitable permanent attachment methods. A number of methods suitable for making the urine bag of the present invention are described in US Patent No. 5,971,613, the contents of which are hereby incorporated by reference in their entirety.

The side panels 3 and 5 are mirror-symmetrical and jointly form a unified structure of the bag 1, which includes a pouring handle 13 connected as one and a hanging loop 23 connected as one. The backsheet 7 is an elongated sheet which is recessed inwardly into the bag 1 body. In one embodiment, the backsheet 7 has two rounded ends (not shown) or pointed ends 17, although other shapes are also suitable for use in the present invention. When the bag 1 is empty, the middle portion 6 and each end portion 17 are at the same or approximately the same distance from the bottom edge 20 . When the bag is full, the end portions 17 are recessed into the bag 1 , that is to say further from the bottom edge 20 than the middle portion 6 which expands towards the bottom edge 20 .

This expansion and flattening of the middle portion 6 takes place as the bag 1 is filled and emptied. Specifically, when the bag 1 is empty, the backsheet 7 is correspondingly in a folded state; while when the bag 1 is filled, the backsheet is in an unfolded state. When the bag 1 is empty and flat, the backsheet 7 is folded together along the longitudinal crease 19 so that the bottom surfaces 2 and 4 are in contact. As the liquid or gas volume in the bag 1 continues to decrease, the front side panel 3 and the rear side panel 5 gradually move closer. The front and rear side pieces 3 and 5 thus exert force on the backsheet 7 so that the backsheet is folded together along the crease 19 . As a result, the crease 19 is pushed further into the bag 1 , ie away from the bottom edge 20 of the bag 1 . When the bag 1 is filled with liquid or gas, the front and rear side panels 3 and 5 are separated, simultaneously allowing the backsheet 7 to unfold. The backsheet 7 stretches outwards along the crease 19 , ie towards the bottom edge 20 of the bag 1 .

Thus, under the pressure or weight of the entering or expanding gas or liquid, the inwardly folded backsheet 7 opens at the bottom end of the bag 1 to stabilize the bag 1 . The force exerted by the gas or liquid presses against the inner surface of the backsheet 7 and the inner surface of each side panel 3 and 5, separating the bottom of each side panel 3 and 5 while providing them with support.

The gravity of the urine collected at the bottom of the bag 1 causes the bottom sheet 7 to expand downwards and separate the front and rear side panels 3 and 5, thereby providing stability for the urine bag 1 to stand up on its own. Sufficient urine gravity separates the front and rear side panels 3 and 5 and simultaneously unfolds the bottom panel 7 so that the bag 1 can stand on its own on a table or other substantially horizontal surface.

The expansion of the backsheet 7 enables direct and simultaneous reading of the volume of urine filled in the bag 1 without the need to use additional measuring instruments. The volume measurement marks 21 are embossed or printed on the front side panel 3, so that the urine volume can be measured correctly without pouring the urine from the bag 1 into another measuring device. Utilizing the self-supporting function of the bag 1, the volume of the contents of the bag 1 can be accurately known by simply visually inspecting the bag 1 when the bag 1 is filled or after filling, eliminating the need to pour the contents of the bag 1 into another measuring cylinder or The other measurement containers are then subjected to such a procedure of measurement.

The front and rear side pieces 3, 5 and the bottom sheet 7 are made of transparent or translucent plastic, but any light and soft material suitable for containing biological fluids can also be used to make these sheets. The lightweight polyolefin plastic sheets 3, 5 and 7 are flexible enough to support a considerable amount of urine, at least that of an adult with a large bladder. When the bag 1 is filled, the sheets 3, 5 and 7 flex and the bottom 15 of uniform thickness supports the filled bag 1 firmly.

When the bag 1 is filled, urine flows into the bag 1 through the fitting 11 , and when the bag 1 is emptied, air enters the bag 1 through the fitting 11 . Fitting 11 is a plastic valve, but it could of course be any suitable valve that performs the dual function described above. Alternatively, more than one accessory may be used to perform both functions.

The bag 1 also has a dual function urination and exhaust valve fitting 9, through which: (1) air or other gas escapes the bag 1 when it is filled with urine; (2) when the bag 1 is full, more Out of the urine overflow bag 1. Fitting 9 is a kind of plastic screw-type closing valve, certainly it also can be suitable, any valve that has above-mentioned two kinds of functions concurrently. Alternatively, more than one accessory may be used to perform both functions.

In one embodiment, the fitting 9 has a circular opening and an eye-shaped bottom. The bottom is connected to the front side panel 3 and the back side panel 5 to provide an air and liquid seal between the bag 1 and the fitting 9 .

Fittings 9 and 11 are made of plastic, but they can also be made of any synthetic or natural lightweight air-impermeable material suitable for containing biological fluids. Fittings 9 and 11 are arranged between the side panels 3 and 5, and can be arranged in any airtight sealing manner.

When collecting urine, the bag 1 can be hung on a bed frame, a movable supporting frame, or other places by the linked link 23. When the bag 1 is full, the bag 1 can be easily removed from the urinary catheter (the catheter is connected to the fitting 11) and can be removed before or after recording the last measurement of urine. During the measurement of the final urine volume, the bag 1 can be easily and safely stood on any flat surface until the urine can be drained from the fitting 9, or the bag 1 can be thrown away together with its contents.

Referring to Fig. 1 a, in one embodiment, the handle 401 is integrally formed with the bag body of the bag 1 as a part of the middle (or bottom) of the right side belt 8, so that the handle 401 is close to the bag 1 filled with urine. The center of gravity provides balance and stability when pouring urine.

Referring to Fig. 3 a, in one embodiment, adopt a bottom insert 151, this insert is solid, incompressible, fitting form and reusable polystyrene foam (Styrofoam ) (Styrofoam ), can ensure that backsheet 7 Can be fully and repeatably deployed. The insert 151 is molded to the same size as the space S, the space inside the bag defined by the lower part 15 of the bag 1 and the backsheet 7 when the backsheet 7 is fully unfolded. Therefore, the length L of the insert 151 is the same as the length M of the space S, and the width N of the insert 151 is the same as the width O of the space S. Furthermore, the top surface 158 is shaped to conform to and contain the outer surface of the fully expanded backsheet 7 .

The insert 151 is inserted into the bottom of the bag 1 in the direction indicated by the arrow 1 to achieve and maintain a complete and repeatable unfolding of the negative sheet 7, providing correct and precise readings without the need to use additional measuring instruments. Volume reading. If the backsheet 7 is not fully extended, for example if the bag 1 is not filled with enough urine, the reading of the volume measurement marker 21 may be incorrect or inaccurate. The above-mentioned incorrect or inaccurate readings will occur whenever the backsheet 7 does not unfold to the same extent regularly and repeatedly for the same amount of urine or other liquid. This irregular expansion can be caused by many variables, such as: atmospheric pressure, temperature, liquid density, fill flow rate, or other variables. Insert 151, and other inserts that will be described below, by providing and maintaining proper distance between the corresponding lengths of front and rear side panels 3 and 5, just can ensure that backsheet 7 is complete, regular, repeatable and repeatedly continuous. spread out.

The insert 151 is attached to the bag 1 using adhesive or other suitable fastening or attachment means. In another mode, the insert is dimensioned such that it fits just snugly in the space S between the backsheet 7 and the bottom 15 . Regardless of the mode, the insert 151 provides and maintains a corresponding appropriate distance between the front and rear side panels 3 and 5, thereby enabling correct and precise measurement of the volume of urine within the bag 1 .

The insert 151 also has a flat bottom 152 which seats against the surface on which the bag 1 is placed. The flat bottom 152 thus further reinforces and maintains the stability of the bag 1 .

Materials suitable for making the insert include, but are not limited to, any solid foam that can be adhesively (or otherwise) attached or secured between the front and rear side panels 3 and 5 . These materials include (but are not limited to): any hard natural or synthetic material, such as wood, plastic, or foam. Of course, any hard material that can provide and maintain the separation of the front and rear side panels 3 and 5 can be used to make the insert 151 .

Referring to Figure 3b, in another embodiment, a rigid and reusable hard plastic frame insert 153 ensures complete and repeatable deployment of the backsheet 7. When the frame insert 153 is inserted into the bottom of the bag 1 in the direction indicated by the arrow I, the backsheet 7 can be fully and repeatably deployed, providing correct and precise volumes without the use of additional measuring instruments read value.

The bottom 154 of the frame insert 153 is flat, enabling it to sit against the surface on which the bag 1 is placed. The flat bottom 154 thus further reinforces and maintains the stability of the bag 1 .

Suitable materials for the frame insert 153 include any rigid material that can adhesively (or otherwise) attach or secure the insert between the front and rear side panels 3 and 5 . These materials include, but are not limited to, any hard natural or synthetic material, such as wood, plastic, or hard foam. Of course, any hard material that can provide and maintain the separation of the front and rear side panels 3 and 5 can be used to make the insert 153 .

Referring to Figure 3c, in another embodiment, a rigid reusable hard plastic spacer insert 155 ensures complete and repeatable deployment of the backsheet 7. When the insert 155 is inserted into the bottom of the bag 1 in the direction indicated by the arrow 1, the insert 155 acts as a spacer to keep the front and rear side panels 3 and 5 at a specified distance along the length of the bottom 15. Although the insert 155 does not span the entire length of the backsheet 7, it is sufficient to keep the front and rear side panels 5 and 3 spaced apart so that the backsheet 7 is fully expanded. In other modes, the insert 155 may be shorter, or made of a thin rigid grid. The result is a complete and repeatable deployment of the film 7, providing correct and precise volume readings without the use of additional measuring instruments.

Materials suitable for making the spacer insert 155 include any rigid plastic that can be adhesively (or otherwise) attached or secured between the front and rear side panels 3 and 5 . These materials include any hard natural or synthetic material such as wood or plastic. Of course, any hard material that can provide and maintain the separation of the front and rear side panels 3 and 5 can be used to make the insert 155 .

Referring to Figure 4, in one embodiment, a closable and elastically expandable reticulated foam insert 300 is placed into the bag 1 before the backsheet 7 is heat welded to the front and rear side panels 3 and 5.

Referring to Figure 5, when the bag 1 is closed, the foam insert 300 separates the front and rear side panels 3 and 5, thereby allowing the backsheet 7 to fully and repeatably unfold.

Referring to Fig. 6, when the bag 1 is evacuated into an outer aseptic container (not shown), the air in the bag 1 is completely exhausted. At this point, the foam insert will close, bringing the front and rear side panels 3 and 5 together to form a flat bag. Before use, the bag 1 can be stored and transported in a flat shape.

Referring to Figure 7, the bag 1 is removed from the aseptic vacuum package just before use, when the bag expands itself due to the elastic expansion of the foam insert 300, which causes the front and rear side panels 3 and 5 and the back panel 7 to bend. Once inflated, the bag 1 is ready for use and stands securely self-supporting on any substantially horizontal plane.

In one embodiment, the foam insert 300 is impregnated with an antimicrobial agent such as a silver-containing zeolite. This antimicrobial material hinders the growth of bacteria within the bag 1, thereby reducing the chances of the patient contracting urine-borne pathogens. Suitable antimicrobials include (but are not limited to): cationic, anionic, non-ionic agents, enzymes and sugar alcohols. Specifically, these substances include (but are not limited to): copper<2+>, zinc<2+>, tin<2+>, alexidine, chlorhexidine, cetyl chloride Cetyl pyridinium chloride, hexidine, quaternary ammonium compounds, sanguinaria extracts, flanders, triclosan, Listerine (R )), other phenolic compounds, disinfectants, medical disinfectants, general purpose detoxifiers and disinfectants.

Referring to FIG. 8 , in one embodiment, a closable and resiliently expandable rigid plastic frame 310 is used in place of the foam insert 300 . The frame 310 can be made of any synthetic or natural material with a certain hardness, as long as the material can restore the frame to its original shape by its own elasticity or other compression springs.

In one embodiment, bag 1 self-inflates after manual depressing of a nitrogen or carbon dioxide generator, such generators being disclosed in US Pat. Nos. 4,832,968 and 5,571,548, which are incorporated herein in their entirety. Other suitable internal air generating chambers may be used as long as they are heat-sealable within the bag 1 between the front and rear side panels 3 and 5. Again, any other non-metallic or metallic internal gas generating chamber can be used in this aspect of the invention.

Referring to FIG. 9 , in another embodiment, a self-standing urine collection bag 100 consists essentially of a cylindrical portion 103 and a bottom 105 . The cylindrical part 103 is made of plastic or coated paper product. The embossed structures 107 in the paper or plastic increase the material strength and increase the stability when the bag 100 is self-supporting, especially when the bag 103 is filled with urine. Suitable materials for making cylindrical portion 103 and bottom 105 include polyolefins. Of course, any hard sealable material that provides a free-standing structure is suitable for this embodiment.

The bottom 105 is formed from a separate sheet in the shape of an inverted pan for plugging the bag. Therefore, other shapes, such as rectangular, circular, oval, etc., that can be attached to and enclosed in the inner side wall 111 of the cylindrical portion 103 are suitable for use as the plug of this embodiment.

The inner wall 111 of the cylindrical portion 103 and the outer wall 109 of the bottom 105 are connected together by suitable adhesive or other bonding methods (eg heat welding). Thus, the bonded area becomes the primary support structure of the bag 100 . This arrangement eliminates the need for an additional insert for the bottom of the stand-up bag.

The bottom 105 of the bag 100 is folded substantially flat over the flattened cylindrical portion 103 when the bag is empty. When ready for use, the bag 100 is unfolded so that the bottom surface of the bottom 105 lies flat on a horizontal surface.

Referring to Fig. 10, the cutout portion 115 of the bag 100 provides ears 117 for the user to place the bag 100 on a hook or other protruding arm. Alternatively, two corresponding holes 108 are hot-melt bonded to form a lug 117 located in the middle of the top of the bag 100 .

A plug-in grab rod (grasp rod) 113 spans from the bottom 105 to the top of the bag 100. The grab bar 113 is heat fused between the sides of the bag 100 and extends freely into the bag 100 . The grab bar can be held at any position of the grab bar 113 . This feature provides operational stability when the user tilts the bag to empty the urine. Before (or after) the walls 111 and 114 of the cylindrical part 103 are joined together, each fitting 9 and 11 is heat-fused into a corresponding hole in the wall 111 .

In another embodiment, fittings 9 and 11 are bonded between walls 111 and 114 when walls 111 and 114 of cylindrical portion 103 are heat sealed, heat bonded, heat welded, or otherwise joined together. .

The drip tube 120 provides a controlled passage of urine into the bag 100, thereby reducing the dripping sound that is common with urine collection bags. A one-way flap valve 123 at the end of the drip tube ensures that urine does not flow back into the drip tube 120 or out of the bag 100 . Of course, any other one-way valve suitable for preventing backflow of urine can be used.

In one embodiment, the user blows into the one-way valve 12, inflates the bag 100 with the gas, and temporarily closes the discharge valve fitting 9 by hand while blowing. This artificial inflation by the user transforms the bag 100 into a semi-rigid container, ensuring that the volume measured according to the markings 21 corresponds exactly to the volume of urine in the bag 100 .

The extra, separate one-way feed valve 12 is only used for artificially inflating the bag 100, not for the subsequent inflow of urine, so bacteria from the user's breath during inflation will not contaminate the urine inflow tube 120. Utilizing the valve 12 can prevent bacteria from growing through the pipeline 120, fittings 11 and the urinary catheter towards the patient, which will reduce the possibility of infection caused by the inflating person bringing bacteria to the patient when the bag 100 is manually inflated.

As can be seen, elastic solid structures and devices that expand within the bag that increase the air pressure within the bag are included within (but not limited to) the types of devices that can be used in this aspect of the invention.

Other embodiments that enhance full deployment of the bag for correct and accurate urine volume measurement, acting externally on the non-deployed bag, will be described below. Referring to Fig. 11, if the urine bag 50 is not fully unfolded, for example, the bag 50 is not filled with enough urine, then the value measured by the mark 57 may be inaccurate. Under the same volume or weight of urine or other liquids, the bag 50 cannot be expanded to the same extent regularly and repeatably, and the capacity value measured by the mark 57 may be inaccurate or imprecise. However, utilizing the tension frame 51 to maintain the distance between multiple opposing interior points within the soft cover of the disposable urine bag 50 at a consistent, repeatable maximum without causing too much pressure, Ensuring full, regular, repeatable, continuous deployment of the bag 50. Frame 51 (like the others described herein) also maintains these distances until an accurate, precise volume measurement is taken. In addition, the frame 51 can be used repeatedly, hygienically, multiple times for multiple disposable urine bags.

Thus, the closable plastic bag 50 fits within the outer frame 51 . When fitted within the frame 51, the bag 50 is held upright in tension so that the exact volume of urine can be measured through the markings 57. The bottom 59 of the bag 50 is pasted with a material (loop material) 60 containing a loop, which can be detachably connected with the hook material 62 on the inner bottom 61 of the frame 51 according to the direction indicated by the arrow Z. In addition, the height X of the bag 50 is equal or substantially equal to the length Y of the frame 51 .

The plastic fastening fitting 63 is fastened into the circular locking connector 65 on the frame 51 in the direction indicated by the arrow E. In this way, the frame 51 is slightly bent and tightened to receive the fitting 63 .

The grip 53 provided by the frame 51 is more stable than the single-use closable bag 50, facilitating emptying of the bag 50. The support bar 69 provides more support to the upper arcuate segments 71 and 73 .

Referring to Figure 12, once fastened in place, the bag 50 will be subjected to appropriate vertical tension from the connector 65, and radial lateral tension from the bottom 61, as can be seen from printed or embossed markings 67. Recheck the correct urine volume measurement. The bag 50 is hooked by the lugs 24 .

The frame 51 is made of rigid plastic, but may be made of any synthetic or natural rigid material suitable for receiving the bag 50 and providing proper vertical tension thereto.

Referring to FIG. 13 , in another embodiment, a plastic bag assembly 238 includes ear fittings 220 , a soft transparent non-self-standing plastic bag 232 , and a diverter cap 210 . These components are all connected to the hard plastic fitting 226. Rigid plastic ear fitting 220 fits circumferentially over cylindrical base 222 of fitting 226 .
