Description

[0001] A urine measuring device

[0002] DESCRIPTION

[0003] The present disclosure relates to a urine measuring device. A urine measuring device may also be referred to as a diuresis device or (hourly) urine meter.

[0004] An example of a urine measuring device is disclosed in US4,265, 118, which is incorporated in the present disclosure by reference.

[0005] A urine measuring device is typically used for intensive care and other critical patients for measuring the amount of urine produced by an intensive care patient. The volume of urine being a vital sign in the monitoring of the patient in the intensive care unit and similar critical and surgical situations.

[0006] The urine measuring device may be used for monitoring the patient for a medium to a long duration of time such as up to five days or longer.

[0007] The urine measuring device comprises a solid / rigid measuring container with a scale for measuring the production / volume of urine. It may comprise a urine bag for emptying the urine from the measuring container into the urine bag.

[0008] Within time intervals such as every hour a nurse reads the volume and then empties the urine measuring device by opening a valve between the measuring container and the urine bag such that the urine may flow from the measuring container into the urine bag.

[0009] A catheter / inlet tube may be used to drain the body of the urine and lead the urine from the body to the urine measuring device.

[0010] The urine measuring device may comprise a drip chamber for isolating the measuring container from the catheter for preventing bacteria to grow into the catheter and bladder.

[0011] The measuring container comprises a filter (sometimes referred to as a valve) for equalizing the pressure inside the measuring container when emptying the measuring container. The filter stops urine from flowing out of the measuring container such that urine will not flow out if the measuring container is laying down. The filter may have pores that are large enough for air to pass through the filter but not large enough for water to pass.

[0012] The filter may outlet displaced air from the measuring chamber when urine drips from the drip chamber and into the measuring container, e.g. the drops of urine displace air, and without the filter there would be an overpressure / excess pressure in the rigid measuring container.

[0013] When the measuring container is emptied the filter equalizes negative pressure that arises due to the emptying, e.g. the filter allows for air to enter the measuring chamber.

[0014] If the pressure equalization is not possible the emptying of the measuring container may last longer time.

[0015] The filter (the pores) may be blocked or become dirty for various reasons - for example if urine comes into contact with the filter (in case the measuring container falls over or is laying down on purpose).

[0016] The more the filter is blocked the less pressure equalizing can be achieved. This may result in the emptying of the measuring container to be very slow, e.g. when the emptying takes place (4 to 48 times per day), the urine is meant to drain by passive (gravity) drainage to the lower hanging urine bag (2 to 4 L size). The volume being emptied may vary from 50 mL to 500 mL. This emptying should last from 5 - 10 sec to 30 - 40 sec, subject to volume being emptied. When a vacuum / under pressure develops in the chamber, often with correlation to the volume of fluid being emptied, due to the drainage process where not enough air is replacing the volume of fluid leaving the measuring chamber; the worst-case situation will almost entirely stop the emptying process, to great irritation of nurses, and cost of nursing and in milder cases of vacuum the urine flow down into the lower bag will be reduced significantly. It is, based on anecdotal evidence believed that volumes > 200 mL (out of 400 mL or 500 mL capacity of the chamber) can cause vacuum related problems for the nurses during such emptying procedures. It can in worst case cause nurses to either having to disconnect the urine-bag, and seek unauthorized pressure neutralization by means of uncontrolled dismantling of the device, or in some cases even compromising the filter by means of puncturing it with a sharp object e.g. hypodermic needle. It may also result in an overpressure being build up in the measuring container not only due to the urine entering the measuring container, but also due to gasses created by microorganisms in the urine for example in cases where the measuring container and the urine inside is exposed to sunlight or heat.

[0017] An overpressure inside the measuring container may also cause the inlet valve in the inlet to the measuring container to become stuck, e.g. the drops of urine pressing down on the valve from the drip chamber cannot overcome the overpressure that has been build up inside the measuring container. This may cause hazard to the patient due to the lack of drainage.

[0018] In any case (whether there is a negative / under pressure or an overpressure) the urine measuring device no longer works as intended.

[0019] It is contemplated that the size of the filter or the number of filters may be increased. However, this will not prevent the underlying problem and only postpone the time until the urine measuring device becomes defect.

[0020] A first aspect of the present disclosure is:

[0021] A urine measuring device for receiving urine from a catheterized patient, said urine measuring device comprising:

[0022] - a measuring container,

[0023] - an inlet to said measuring container, and

[0024] - an outlet for emptying contents of said measuring container into a urine bag.

[0025] A second aspect of the present disclosure is:

[0026] A method for measuring urine volume from a catheterized patient, said method comprising:

[0027] - providing a measuring container including an inlet to said measuring container, an outlet for emptying contents of said measuring container into a urine bag, and a scale for measuring the volume of urine produced from said catheterized patient, and

[0028] - reading said scale at a time interval.

[0029] The outlet may also be termed a port or exit.

[0030] The urine measuring device may comprise a filter for equalizing a pressure difference between the inside of said measuring container and the outside of said measuring container.

[0031] The urine measuring device may comprise an opening with a movable closure. The opening may be arranged closer to the top of the measuring container than the bottom of the measuring container.

[0032] In the following examples according to aspects of the present disclosure will be explained in more detail with reference to the accompanying drawings. The present disclosure may, however, be embodied in different forms than depicted below and in the drawings, and should not be construed as limited to any examples set forth herein. Rather, any examples are provided so that the disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals refer to like elements throughout. Like elements will, thus, not be described in detail with respect to the description of each figure.

[0033] Fig. 1 illustrates an example of a urine measuring device including a urine bag 10 below the urine measuring device.

[0034] The urine measuring device includes a measuring container 12. The measuring container has a transparent front side with a scale 14.

[0035] The side with the scale is referred to as the front side in the present disclosure. As such only the area of the front side that includes the scale need to be transparent or semi transparent, e.g. possible to see through the side to a degree such that the urine inside the measuring container is visible. It is shown that the scale goes up to 500 mL, e.g. the measuring container has a volume of 500 mL. In general, the volume may be in the range 100 mL to 2 L or more.

[0036] The measuring container may be manufactured in two pieces, e.g. a top piece / lid 16 and a bottom piece including a bottom and four sides extending upwards from the bottom - a front side with the scale, a back side and a right and left side.

[0037] The two pieces may be molded and glued together. The entire bottom piece may be transparent and the top piece may be non transparent, e.g. made in a less costly material than the bottom piece. The top piece may include the backside - in such a case the bottom piece only has three sides.

[0038] The measuring container may be rigid. It may be made of a rigid plastic. Rigid plastic means any item that: (i) is composed predominantly of plastic resin; (ii) has a relatively inflexible fixed shape or form; and (iii) is capable of maintaining its shape or form, whether empty or full, under normal usage, independent of any product that it contains or other external support. An example of a polymer material could be rigid PVC.

[0039] Said in other words, the measuring container is to be more rigid than the urine bag, which is inflatable, e.g. expandable.

[0040] % Lid

[0041] The lid may comprise a removable section - for example a plate that is flush with the rest of the lid.

[0042] The section may be slided into position, and it may be secured to the lid by means of a snap-fit.

[0043] It may have an area corresponding to no more than 20 % of the area of the lid. It may be rectangular, and may have a size of about 6 by 4 cm.

[0044] The removable section may comprise a (new) filter such that the (old) filter may be replaced when it has become blocked. Alternatively, or in addition to, the section may comprise the opening with the movable closure - the DFPS (dual function pressure system).

[0045] On top of the lid is illustrated a drip chamber 18.

[0046] It is shown that the catheter 20 connects to the urine measuring device via the drip chamber. The drip chamber is optional, e.g. the catheter may be connected directly to an inlet to the measuring container.

[0047] The drip chamber serves to isolate the measuring container from the catheter.

[0048] The drip chamber may be shaped as a cylinder. Alternatively, it may be tapered, e.g. the bottom having a larger area than the top.

[0049] The size of the drip chamber may correspond to twice the size of an average size thimble, e.g. the drip chamber may have a diameter up to 40 mm.

[0050] The bottom of the drip chamber may have an outlet surrounded by a surface such as an annular surface.

[0051] The circumference of the drip chamber may be round or it may be defined by a polygon.

[0052] The outlet may be round or it may be a polygon.

[0053] Instead of the annular surface being defined by two concentric rings it may be defined by two concentric polygons.

[0054] It is shown that inside the drip chamber is a tube extending down from the top. This is to align where the urine drips inside the drip chamber such that the urine drops down into the outlet and not lands on the surface around the outlet.

[0055] The drip chamber may comprise a filter for maintaining a dry environment, e.g. if any urine does land on the surface around the outlet it vaporizes and exits through the filter. In this way it becomes difficult for bacteria to grow inside the drip chamber and spread to the catheter / inlet tube. The filter may be arranged closer to the top of said drip chamber than the bottom. The drip chamber is illustrated as arranged on top of the lid. It may also be placed inside the measuring container or arranged at one of the sides of the measuring container.

[0056] The (inlet) valve between the drip chamber and the measuring container may be a nonreturn valve.

[0057] The drip chamber may be made in two pieces, e.g. a lid and a bottom with side(s) extending up from the top.

[0058] The drip chamber may be glued to the measuring container.

[0059] The drip chamber may be made in a material comprising an anti-microbial material such as silver or cobber, e.g. this material may be mixed into the polymer used to make the drip chamber. Specifically, the bottom and the side(s) may be made in a material comprising an anti-microbial / bacterial material.

[0060] The filter 24 for equalizing the pressure inside the measuring container is illustrated as being arranged in the lid of the measuring container. However, it may be placed elsewhere such as on one of the sides of the measuring container. It is preferably arranged closer to the top of the measuring container than the bottom such as in the top 25 % of the measuring container, e.g. the distance to the top is not greater than 25 % of the distance to the bottom.

[0061] There may be a plurality of filters.

[0062] % opening

[0063] Also illustrated is an opening with a movable closure 26.

[0064] The movable closure may move between an open state and a closed state. In the open state air may pass through the opening.

[0065] When an overpressure or under pressure has developed inside the measuring container the movable closure may be moved from the closed state into the open state / position such that the pressure inside the measuring container may be equalized. For example, when emptying the measuring container for urine - especially in cases where the filter in the measuring container is stopped.

[0066] The movable closure may be removably connected to the opening such that the closure may be removed from the measuring container / opening, e.g. a removable plug. The plug may be connected to the measuring container by means of a string.

[0067] The movable closure may constitute a male part for fitting into a female part of the opening, e.g. the passage may constitute a female part for inserting the male part of the closure into.

[0068] The measuring container may comprise a mechanical spring connected to the movable closure acting on the movable closure.

[0069] A button in contact with the movable closure may be provided for counteracting the spring. When the button is pressed / depressed by an operator, the movable closure is forced to the open state as long as the button is pressed and when the button is released the spring forces the movable closure to the closed state. The operator has to overcome the spring force in order to keep the movable closure in the open state.

[0070] In another example, the spring may have a spring constant and deformed from its equilibrium position / state such that when there is a pressure difference between the inside of the measuring container and the outside (the environment) the pressure difference overcomes the spring force and forces the movable closure into the open state. The spring may be deformed up to 80 % of the total possible deformation of the spring and have a spring force such that when the pressure difference is more than 10 % of standard atmospheric pressure the spring force is overcome and the movable closure is moved to an open position.

[0071] There may be two springs for acting on the movable closure. Alternative, there may also be two openings, each having a closure for closing and opening into the measuring compartment. Each closure being acted upon by a spring.

[0072] One spring may be acted upon by an overpressure such that the (first) closure is moved to an open position when the overpressure overcomes the spring force. The other spring may be acted upon by an under pressure such that the (second) closure is moved to an open position when the overpressure overcomes the spring force. The spring constants may be different and / or the two springs may have different displacement / deformation with respect to their equilibrium positions.

[0073] The movable closure may be constituted by a silicone membrane (with two lips for example) where a needle may be pressed into the membrane causing an opening in the membrane such that air may pass through the opening.

[0074] The opening may also be used for taking a sample of the urine inside the measuring container or a series of samples representing a set duration of urine e.g. 12 hours or 24 hours, e.g. using an empty syringe and retracting / extracting urine into the syringe.

[0075] Alternative, a pipe may be inserted through the opening into the measuring container either for injecting a cleaning liquid into the measuring container or extracting a urine sample by means of the pipe.

[0076] % urine bag

[0077] A urine bag may be connected to the measuring container - such as arranged below the measuring container.

[0078] The measuring container may comprise a hanger for handing the urine bag on the measuring container.

[0079] The urine bag may comprise a superabsorbent polymer (SAP powder) also called slush powder.

[0080] The measuring container has an outlet 22 for emptying the contents of the measuring container into the urine bag. The outlet comprises a valve. The valve may be manually operated by means of a handle. The outlet may be arranged at the bottom of the measuring container.

[0081] It is illustrated that the outlet is arranged at the bottom of the measuring container at the center / in the middle of the container. However, the outlet may also be arranged at one of the sides (either the right or the left side). The measuring container may comprise a movable cylinder inside the container, and the scale may be aligned with the cylinder. The outlet may be arranged below the cylinder. The cylinder is arranged to move up and down for opening and closing the outlet. When the cylinder is down the outlet is closed. Thus, in this example, the cylinder also constitutes the outlet valve, and the handle may be arranged on top of the measuring container. The handle is arranged such that moving the handle causes the cylinder to move up and thereby open the outlet.

[0082] % US type emptying

[0083] In an alternative configuration, the outlet (port between the measuring container and the urine bag) may be arranged with a distance to the bottom, for example closer to the top of the measuring container than the bottom.

[0084] In this case, the measuring container may be emptied by tilting it such that the urine flows out of the exit port. This is a different type of emptying than described above, e.g. with the urine bag arranged below the measuring container and a valve operated by turning a handle for opening the port between the measuring container and the urine bag.

[0085] Typically, the port between the measuring container and the urine bag is arranged on another side of the measuring container than the scale for measuring the urine volume, for example arranged on the back side of the measuring container (opposite the front side with the scale).

[0086] It is contemplated that the exit port may comprise a non-return valve such that urine cannot flow back into the measuring container.

[0087] This type of urine measuring device does not necessarily need a filter for equalizing pressure in the measuring container. However, if a non-return valve is arranged between the measuring container and the urine bag it is contemplated that the measuring container may comprise an opening with a movable closure such that when an overpressure or under pressure has developed inside the measuring container the movable closure may be moved from the closed state into the open state / position such that the pressure inside the measuring container may be equalized.

[0088] % Luer taper It is contemplated that the opening in the measuring container (whether it is on a US type urine measuring device or a non US type) is defined by one half of a Luer taper connection for connection with the other half of a Luer taper connection, e.g. either a male or female Luer lock fitting. For example, the measuring container may comprise a female Luer-Lock fitting for screwing a syringe with a male Luer-Lock fitting onto it or vice versa.

[0089] When an overpressure has resulted in the inlet valve being arrested or not able to move such that urine can drip into the measuring container the closure may be removed and the syringe screwed onto the fitting such that pulling the plunger of syringe can cause an under pressure in the measuring container forcing the arrested valve back into normal operation.

[0090] The measuring container may be cleaned by filling a syringe with a cleaning liquid such as a saline solution. The syringe may then be screwed onto the Luer taper connection and the cleaning liquid injected into the measuring container.

[0091] % anti-bacterial material

[0092] The measuring container may comprise a passage defining the opening, e.g. the opening is located in the passage.

[0093] The passage may have a length greater than the thickness of the wall or lid of the measuring container. The passage may define a channel for the flow of air. The air flow having a path through the passage. The length of the path being greater than the thickness of the wall or lid of the measuring container.

[0094] Providing the measuring container with an opening in addition to the filter (this opening not having a filter) may increase the risk of contamination, e.g. risk of urine escaping through the opening.

[0095] The passage may be made in a material comprising an anti-microbial material such as silver or cobber, e.g. this material may be mixed into the polymer used to make the passage.

[0096] This may reduce bacterial growth in the passage. The measuring container may comprise a second passage defining the outlet to the urine bag. This passage may be made in a material comprising an anti-microbial material such as silver or cobber, e.g. this material may be mixed into the polymer used to make the second passage.

[0097] The urine bag has a urine bag outlet 24, which may comprise a valve. In this case illustrated as a cross valve. The valve may also be manually operated.

[0098] The urine bag may comprise a third passage defining the urine bag outlet. This passage may be made in a material comprising an anti-microbial material such as silver or cobber, e.g. this material may be mixed into the polymer used to make the third passage.

[0099] % urine bag with drip chamber

[0100] It is contemplated that a urine bag may comprise the same type of drip chamber as described above for the urine measuring device, e.g. at the inlet to the urine bag there may be arranged a drip chamber for isolating the inside of the urine bag from the inlet tube.

[0101] The bottom of the drip chamber may have an outlet surrounded by a surface such as an annular surface.

[0102] The circumference of the drip chamber may be round or it may be defined by a polygon.

[0103] The outlet may be round or it may be a polygon.

[0104] Instead of the annular surface being defined by two concentric rings it may be defined by two concentric polygons.

[0105] It is shown that inside the drip chamber is a tube extending down from the top. This is to align where the urine drips inside the drip chamber such that the urine drops down into the outlet and not lands on the surface around the outlet.

[0106] The drip chamber may comprise a filter for maintaining a dry environment, e.g. if any urine does land on the surface around the outlet it vaporizes and exits through the filter. In this way it becomes difficult for bacteria to grow inside the drip chamber and spread to the catheter / inlet tube. The (inlet) valve between the drip chamber and the urine bag may be a non-return valve.

[0107] The drip chamber may be made in two pieces, e.g. a lid and a bottom with side(s) extending up from the top.

[0108] The drip chamber may be glued to the urine bag.

[0109] The drip chamber may be made in a material comprising an anti-microbial material such as silver or cobber, e.g. this material may be mixed into the polymer used to make the drip chamber. Specifically, the bottom and the side(s) may be made in a material comprising an anti-microbial / bacterial material.

[0110] The urine bag may comprise a superabsorbent polymer (SAP powder) also called slush powder.

[0111] % urine bag with an opening

[0112] It is contemplated that a urine bag may comprise the type of opening with a movable closure as described above for the measuring container, e.g. an opening defined by one half of a Luer taper connection for connection with the other half of a Luer taper connection, e.g. either a male or female Luer lock fitting. For example, the urine bag may comprise a female Luer-Lock fitting for screwing a syringe with a male Luer-Lock fitting onto it or vice versa.

[0113] Or as mentioned, an opening where the movable closure is connected to a mechanical spring either for automatic activation / opening of the opening or by means of a push button.

[0114] The movable closure may be removably connected to the opening such that the closure may be removed from the urine bag / opening, e.g. a removable plug. The plug may be connected to the urine bag by means of a string.

[0115] The movable closure may constitute a male part for fitting into a female part of the opening, e.g. the passage may constitute a female part for inserting the male part of the closure into. In this case such a urine bag may be cleaned in the same way as described for the measuring container.

[0116] The urine bag may comprise a filter for equalizing pressure inside the urine bag.

[0117] The urine bag may also comprise a drip chamber as described above.

[0118] % drip chamber with opening

[0119] In general, whether a drip chamber is arranged on a urine measuring device or on a urine bag or on another device for collecting a bodily fluid such as urine, the drip chamber may in itself comprise a type of opening with a movable closure as described above both for a urine measuring device and a urine bag, e.g. it is contemplated that a drip chamber may comprise an opening with a movable closure - for example, an opening defined by one half of a Luer taper connection for connection with the other half of a Luer taper connection, e.g. either a male or female Luer lock fitting.

[0120] For example, the drip chamber may comprise a female Luer-Lock fitting for screwing a syringe with a male Luer-Lock fitting onto it or vice versa.

[0121] The movable closure may be removably connected to the opening such that the closure may be removed from the drip chamber / opening, e.g. a removable plug. The plug may be connected to the drip chamber by means of a string.

[0122] The movable closure may constitute a male part for fitting into a female part of the opening, e.g. the passage may constitute a female part for inserting the male part of the closure into.

[0123] In this case such a drip chamber may be cleaned in the same way as described for the measuring container.

[0124] The opening may be arranged such that when injecting a cleaning fluid into the drip chamber, the flow of the cleaning has a path / trajectory towards the bottom of the drip chamber, specifically such that the cleaning fluid comes into contact with the surface surrounding the outlet of the drip chamber, e.g. where the non return valve is also arranged. Said in other words, the opening faces the bottom of the drip chamber. For example, the opening could be arranged approximately half way between the top and bottom of the drip chamber (+ / - 20 % of the distance between the top and bottom of the drip chamber) and preferably be inclined / tilted towards the bottom of the drip chamber. The opening with the movable closure could also be arranged at the top of the drip chamber such that cleaning fluid may drop down towards the bottom of the drip chamber.
