This application claims the benefit of the filing date of U.S. Provisional Patent Application 63/379,606 entitled “URINARY CATHETER URINE COLLECTION BAG WITH REPLACEABLE DRAIN BLOCKAGE FILTER” to Peterson, et al. that was filed on Oct. 14, 2022, the disclosure of which is hereby incorporated herein by this reference.


TECHNICAL FIELD
Aspects of this document relate generally to a urinary catheter urine collection bag, and more specifically to urinary catheter urine collection bag with a replaceable drain blockage filter.
BACKGROUND
According to the CDC (“Center for Disease Control”), an estimated 75% of all urinary tract infections (“UTIs”) inside a hospital are caused by urinary catheters, also known as Foley catheters. Blockages of urinary catheters caused by blood, bacteria, and mineral deposits can lead to complications with in-care and out-care patient treatment. Each catheter connects to a collection bag for urine drainage. The healthcare professional may empty the collection bag of urine while the collection bag is still attached to the patient through a spout at the base of the bag.
Often however, because many patients needing a urinary catheter are in the hospital due to trauma or surgery, the patient has blood in their urine, including blood clots. Other blockages can also form in the collection bag through bacteria and mineral deposits. The blockages settle at the bottom of the bag before draining. The build-up of blockage material at the bottom of the bag often blocks the drain tube and hinders the healthcare professional from emptying the collection bag. To remove the blockage material buildup, healthcare professionals currently manipulate the blockage materials by handling the bag and pushing clots out of the way to drain the urine, which is not always effective or only temporarily effective until the number or magnitude of the blockage materials exceeds the ability to push them out of the way. When manual manipulation fails to allow for draining around the blockage materials, the healthcare professional is required to remove the urinary catheter from the patient entirely and replace it with a new one. Removal of a blocked urinary catheter and attachment of a new urinary catheter is not only uncomfortable and sometimes painful for the patient, it causes an increased likelihood of UTIs.
There are currently no known, effective methods or devices on the market for removing blood clot blockages in a urinary catheter collection bag drain. The problem is well known and persistent since the introduction of urinary catheters to the extent that methods have been developed, such as by using a dye, to inform healthcare professionals when an infection is imminent, and pre-treating patients with antibiotics in catheter systems to reduce the likelihood of UTIs. However, overuse of antibiotics increases antibiotic resistance and the likelihood of development of superbug infections and are, thus, undesirable.

More specifically, this disclosure, its aspects and embodiments, are not limited to the specific material types, components, methods, or other examples disclosed herein. Many additional material types, components, methods, and procedures known in the art are contemplated for use with particular implementations from this disclosure. Accordingly, for example, although particular implementations are disclosed, such implementations and implementing components may comprise any components, models, types, materials, versions, quantities, and/or the like as is known in the art for such systems and implementing components, consistent with the intended operation.
The present disclosure is related to a urinary catheter urine collection bag assembly 100 with a bag 102 and a blockage filter 104 that is configured to capture blood clots, bacteria, minerals, and other blockage material settling to the bottom of the bag 102. Thus, when urine is drained out of the bag 102, the blockage material is limited in its ability to block the drainage tube 108 because the blockage material has been gathered out of the urine by the blockage filter 104 before the urine passes through the drainage tube 108. Thus, the urine collection bag assembly 100 is designed to increase the amount of time that a urinary catheter remains useful and decrease the need for placement of a new catheter and the accompanying increased likelihood of a UTI or other infection.
As shown in FIG. 1, the urine collection bag assembly 100 may comprise a bag 102, a blockage filter 104, a urinary catheter 106, a drainage tube 108, and a flow valve 110. Some embodiments of the urine collection bag assembly 100 may exclude some of these components and other components may be added.
The bag 102 may have an upper end 112 and a lower end 114 opposite the upper end 112. The upper end 112 may have an inlet 116 into the bag 102 and the lower end 114 may have an outlet 118 out of the bag 102. However, in other embodiments, the inlet 116 and the outlet 118 may be positioned in any other position on the bag 102. The bag 102 may have any shape and may have a hook, loop or other type of hanger 120 at the upper end 112 to provide a convenient way to suspend the bag 102 from a supporting structure. Because the blockage material sometimes settles out of the urine over a period of time, the blockage filter 104 may be positioned such that, when the bag 102 is suspended from the hanger 120, the blockage filter 104 is positioned below the hanger 120. However, other embodiments are also contemplated. Although FIG. 1 illustrates the blockage filter 104 facing downward, for convenience, this orientation is not required for functionality of the collection bag assembly 100.
The urinary catheter 106 may be fluidly coupled to the inlet 116 of the bag 102 such that when fluid, such as urine, flows through the urinary catheter 106 to the bag 102, the urine exits the catheter 106 and enters the bag 102 through the inlet 116. Thus, the urinary catheter 106 may be configured to pass urine from a patient to the bag 102. The urinary catheter 106 may be any size, any length, and any shape. In some embodiments, as shown in FIG. 1, an optional urinary catheter 106 catch, shown above reference number 114, may be included for convenience that is sized and configured to receive the urinary catheter 106 and hold it in place against the bag 102 when not in use.
The drainage tube 108 may be fluidly coupled to the outlet 118 and may be configured to pass urine out of the bag 102. The drainage tube 108 may have a stop 122 that restricts the flow of urine through the drainage tube 108, such as a clamp, a crimping mechanism, or a valve. The function of the stop 122 is simply to allow the user of the urine collection bag assembly 100 to decide when to allow urine to drain out of the bag 102. Thus, the catheter 106, the inlet 116 of the bag 102, the bag 102 itself, the outlet 118 of the bag 102, and the drainage tube 108 may all be actively fluidly coupled together without the urine draining out through the drainage tube 108 because the stop 122 restricts the flow.
As described above, the drainage tube 108 sometimes becomes blocked by blood clots and other blockages that form in the urine. Thus, before the urine passes through the drainage tube 108, the blockage filter 104 may be configured to filter the urine to remove any potential blockages. The blockage filter 104 may be positioned between the bag 102 and the drainage tube 108 such that urine must pass through the blockage filter 104 to reach the drainage tube 108 and empty out of the bag 102.
As shown in FIGS. 2-3, the blockage filter 104 may have a cup 124 that has a cup wall 126 and a plurality of slits 128 extending through the cup wall 126. In some embodiments, only one slit 128 may be implemented. The slits 128 may be sized to block any blockage material that is large enough to cause issues in the drainage tube 108. Thus, when urine flows through the blockage filter 104 by flowing into the cup 124 and then through the slits 128, the blockage material may flow with the urine and become entrapped in the cup 124. The slits 128 may be oriented to extend up the walls 126 of the cup 124. This allows the filter 104 to function for a greater amount of time because, as the filter 104 blocks blockage material from entering the drainage tube 108, the cup 124 begins to fill with blockage material. As the cup 124 fills, a greater portion of the slit 128 may be covered. In embodiments with slits 126 that extend up the cup wall 124, urine is still able to pass through the filter 104 until the cup 124 is completely full and the last portion of the slit 128 is blocked. At this point, the filter 104 or the cup 124 may be separately replaced to avoid the need to replace the entire urine collection bag assembly 100, as described in more detail below.
Additionally, the blockage filter 104 may have a filter housing 130. The cup 124 of the blockage filter 104 may be configured to sit inside of the filter housing 130, and in some embodiments, the filter housing 130 is fluidly coupled to the drainage tube 108, and thus urine that passes through the filter housing 130 is filtered through the cup 124 and then passes to the drainage tube 108. The filter housing 130 may have any shape.
The blockage filter 104 may be removable. For example, the blockage filter 104 may be threadedly coupled or otherwise removably coupled to the flow valve 110 and/or the bag 102. Thus, when the blockage filter 104 needs to be cleaned or replaced, the blockage filter 104 can be removed from the flow valve 110 or the bag 102 rather than requiring that the entire collection bag assembly 100 be replaced. For embodiments that include a flow valve 110, this may include first, moving the flow valve 110 to the closed configuration, as described in more detail below, so that flow to the blockage filter 104 is stopped while the blockage filter 104 is removed and cleaned or replaced.
The flow valve 110 is configured to selectively block the flow of urine from the bag 102 to the blockage filter 104. Thus, the flow valve 110 may have an open configuration and a closed configuration, as shown in FIGS. 4-7. When in the open configuration (FIGS. 4 and 5), the flow valve 110 permits the flow of urine from the bag 102 to the blockage filter 104 and when in the closed configuration (FIGS. 6 and 7), the flow valve 110 stops the flow of urine from the bag 102 to the blockage filter 104. In some embodiments, the flow valve 110 is positioned between the bag 102 and the blockage filter 104. Thus, the flow valve 110 may be fixedly attached to the bag 102 and may be removably coupled to the blockage filter 104 to allow the blockage filter 104 to be replaced as described above. The flow valve 110 may be a one-way valve. This may help to hinder bacteria from traveling from the patient's surroundings, through the flow valve 110, and up through the collection bag assembly 100 and into the patient, causing UTIs and other infections.
The flow valve 110 may have a body 132 and at least one valve arm 134. Each of the at least one valve arm 134 may be slidably coupled with a corresponding opening 136 in the body 132. When the flow valve 110 is moved from the open configuration to the closed configuration, the valve arm 134 may be moved further into the corresponding opening 136. Thus, to move the flow valve 110 into the open configuration from the closed configuration, the valve arm 134 must be pushed further into the corresponding opening 136 while, to move the flow valve 110 into the closed configuration, the valve arm 134 must be pulled further out of the corresponding opening 136. Each of the valve arms 134 may be locked into its corresponding opening 136 such that the valve arm 134 is restricted from completely exiting the opening 136. In some embodiments, a larger flow valve 110 may be implemented to maintain any contaminated surfaces within the flow valve 110. In addition, sealing materials and coatings are contemplated to decrease the likelihood of urine or contaminants escaping the flow valve 110.
In embodiments where the flow valve 110 is positioned at the bottom of the bag 102, blockage material that settles out of the urine within the bag 102 may tend to collect on the surfaces of the flow valve 110. In particular, if the flow valve 110 is left in the closed configuration, blockage material may build up on the valve arm 134 because the valve arm 134 is directly in the path of flow. This is not a problem unless the buildup inhibits the valve arm 134 from moving from the closed configuration to the open configuration. Thus, in some embodiments, when the flow valve 110 is moved from the closed configuration to the open configuration, the corresponding opening 136 may be configured to remove buildup from the valve arm 134. Because this motion opens up the flow valve 110 and allows urine to flow through the blockage filter 104, the blockage filter 104 catches any buildup removed from the valve arm 134 and filters it out of the urine so that the drainage tube 108 removes free of any blockage.
As illustrated in FIG. 8, a method of draining urine from a patient may comprise inserting a catheter into the patient, draining urine from the patient through the catheter, collecting the urine in a urine collection bag 102, filtering blockage material out of the urine with a blockage filter 104, and passing the urine out of the collection bag 102. As mentioned above, the blockage filter 104 may be positioned between the collection bag 102 and the drainage tube 108.
The method may also comprise replacing the blockage filter 104 with a replacement blockage filter 104. Typically, to replace the blockage filter 104, the bag 102 must be fluidly decoupled from the blockage filter 104 so that the filter 104 can be replaced without leaking urine out of the bag 102. This is the purpose of the flow valve 110, which blocks flow of urine from the bag 102 to the blockage filter 104. Once the flow valve 110 is in the closed configuration, the filter 104 can be removed and cleaned or removed and replaced by another blockage filter 104. This avoids the need to replace the entire collection bag assembly 100 and helps to maintain a barrier between the patient's environment and the urinary tract. Additionally, this removes the need for a medical professional to spend much more than a couple of second performing the change, and thus saves the patient money. Thus, the method may additionally comprise moving the flow valve 110 to a closed configuration to stop flow of urine through the blockage filter 104, replacing the blockage filter 104 with a replacement blockage filter 104 after moving the valve 110 to the closed configuration, and moving the valve 110 to an open configuration to allow flow of urine through the replacement blockage filter 104 after replacing the blockage filter 104 with the replacement blockage filter 104.
Embodiments of the present disclosure provide three primary advantages: cost-efficiency, low maintenance demands, and simplicity. The cost of replacing a urinary collection bag for a patient while in-care can vary depending on the patient, but in any case costs over a hundred to hundreds of dollars to replace when taking into account healthcare professional time and equipment. When the increased risk of infection and the cost of treating UTI infections and risk to the hospital for lawsuits and patient dissatisfaction is taken into account, the cost of the problem is ridiculously high. The solution embodied in this disclosure that enables healthcare professionals to remove blood clots in a urinary catheter collection bag drain line without replacing the entire catheter, and without additional risk of contamination or infection enables the patient and the hospital to save money, time and resources in addition to the significantly reduced risk of UTIs and the risks associated with them.
Secondly, after initial placement of the urinary catheter, maintenance of the urinary catheter collection bag for healthcare professionals is minimal. The collection bag, and associated urinary catheter, does not require replacement due to a blood clot because the simple switching of a filter immediately restores flow.
Finally, a clogged filter is easily interchangeable with a new sterile filter because of the simplistic and modular design. A healthcare professional can easily remove and replace a filter while maintaining a clean environment for themselves and their patient. The simple device minimizes patient discomfort and risk.
In hospitals and surgery centers, time and financial strains are placed on both the facility and the patients if a urinary tract infection (UTI) occurs, following the placement of a urinary catheter system. This can extend patient stays and requires more time from the provider and nurses for removing and replacing the product. Hospitals and surgery centers are likely to have less frequent occurrences of infections if they are using the urine collection bag assembly 100 with a replaceable blockage filter 104 according to this disclosure. The urine collection bag assembly 100 also has the benefit of providing a more affordable and user-friendly option for urinary catheters. The urine collection bag assembly 100 allows a patient to even empty their own bag 102 or replace their own filter 104 because it is done remote from the patient's body and does not involve re-setting the catheter into the patient's body. Additionally, the urine collection bag assembly 100 reduces common frustrations experienced by health care professionals due to blocked drains.
Manufacture of the urine collection bag assembly 100 may be accomplished using known molding techniques by those of ordinary skill in the relevant art. Because the device is used in the medical industry, medical grade materials, such as medical grade plastic, hard plastics, and plastics resistant to contaminants and infection, may be used. Biomaterial filters may also be employed to further resist the spread of contamination. The blockage filter 104 and flow valve 110 may be manufactured integral with a urinary catheter and collection bag or manufactured separately and adapted for easy attachment to the collection bag as needed for particular implementations.
In some embodiments, the blockage filter 104 and the flow valve 110 may be manufactured as a replaceable filter system 140 that comprises the filter housing 130, the blockage filter 104, the flow valve 110 with a valve arm 134, and a coupler 138 for joining the blockage filter 104 to the flow valve 110. Such a system is illustrated in FIGS. 2 and 3. As discussed above, the flow valve 110 may be coupled to a lower end 114 of the urine collection bag 102 so that gravity draws the urine through the flow valve 110 and out the drainage tube 108 in fluid communication with the blockage filter 104. The various components may be coupled together according to their various purposes as needed using any methods known in the art. In particular, adhesive, such as medical grade adhesive, heat welding, press-fit, mechanical engagement, such as through, without limitation, a quarter-turn bayonet coupling or threaded coupling, are contemplated for use. Though it is not required, the coupler 138 may be permanently coupled to the flow valve 110 and removably coupled to the filter housing 130, such as through threading, with the filter 104 positioned within the combination of the coupler 138 and the filter housing 130 so that fluid flowing through the flow valve 110 passes the valve arm 134, continues through the coupler 138 and the filter 104 to then exit the system through the filter housing 130 into the associated drainage tube 108. This particular design, or another if used, may also be configured as a one-way flow valve to further resist the chances of infection or contaminants passing back up into the collection bag 102. In the medical industry, it is conventional to use tubes as drains for urinary catheter collection bags, and so it is anticipated that an appropriate tube similar to that presently used with urinary catheter collection bags will be used, but other structures may also be suitable and are contemplated in place of the drainage tube 108.
