Description

[Technical Field]

[0001] The present disclosure relates to a drainage bag storage device that stores a urobag (urine collection bag; drainage bag) connected via a collection tube to an artificial bladder pouch or an indwelling urinary catheter attached to a patient. [Background technology]

[0002] A urobag is an external urine collection bag that is attached to a pouch with limited capacity to increase its capacity and collect urine for a longer period of time. It is primarily used during sleep. Furthermore, the polymeric material that makes up the pouch or urobag dissolves and deteriorates with urination, so pouches need to be replaced with new ones every five days and urobags every two weeks. In contrast, drainage bag storage devices can be used for a long period of time until they are physically damaged. In the following explanation, the bladder and artificial bladder will be collectively referred to as the bladder, and bladder height will be described as the height above the mattress. Furthermore, we will use the artificial bladder pouch as a representative example, and may omit explanations of indwelling urinary catheters.

[0003] Urostomy patients in nursing homes or at home have a pouch attached to their abdomen that collects urine from their urostoma (artificial bladder), which is then collected in a urobag via a collection tube. There are currently approximately 50,000 patients with pouches, and the number is increasing by several thousand each year. In addition, during the post-operative rest period in hospitals, it is common practice to place an indwelling urinary catheter in the patient's bladder via the urethra to collect urine, which is then stored in a urobag via a collection tube. More than one million patients are fitted with indwelling urinary catheters each year.

[0004] FIG. 8 shows the external view of a hanging urobag and a nursing bed. The urobag 51 (drainage bag) described above has a top end for carrying, with a handle hole 51a for hooking a finger or a hook, or two hanging holes 51b for passing a hanging string 55. A check valve 52a connected to a collection tube 52 is provided at the top end. Below that is a urine collection bag portion 51c, which accounts for the majority of the urobag 51. At the bottom end is a drain port 51d for discharging accumulated urine by gravity. Typically, the urobag 51 is hung by engaging the upper curved portion 54a of an S-shaped hook 54 with a handrail frame 53a standing on the frame 53 of a nursing bed, and then engaging the lower curved portion 54b of a loop-shaped hanging string 55, which is passed through the hanging hole 51b of the urobag 51.

[0005] In the case of a hanging urobag, as shown in FIG. 8 , one end of the collection tube 52 is connected to the check valve 52a of the urobag 51, and the other end is detachably connected to an artificial bladder pouch (not shown). The urobag 51 is suspended from a handrail frame 53, and urine is collected by gravity. Therefore, to collect urine, the highest point of the urobag 51 must be positioned sufficiently lower than the top surface of the mattress 56 of the nursing bed (i.e., the bladder level). However, if the height of the urobag 51 is too low, the bottom of the urobag 51 may come into contact with the floor F, potentially causing bacterial infection of the outlet 51d. Therefore, the height of the urobag 51 must be low enough to ensure stable collection of effluent, yet must not come into contact with the floor for hygienic reasons. Due to this constraint, a hanging device for mounting the urobag 51 on the handrail frame 53 requires a height adjustment function.

[0006] The following has been proposed as a device for attaching a urobag: A mounting member with a hook is attached to the side of the opening, which is smaller than the diameter of the vertical bars of the bed rails, and the urobag is suspended from the mounting member with the hook at an appropriate position on the low-bed rails, below the patient's bladder and so that the bottom of the urobag does not come into contact with the floor (see Patent Document 1; JP 2008-54868 A). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-54868 Summary of the Invention [Problem to be solved by the invention]

[0008] In a hanging urobag, the urine in the collection tube is collected by gravity. However, the bladder to urobag is a closed urine collection system, and the collection tube and pouch are under slightly negative pressure compared to atmospheric pressure. For the urobag to generate a suction force greater than this negative pressure to collect urine, a large difference in height, or head, is required between the bladder and urobag. If the head is too small, urine will not flow smoothly and will remain in the collection tube or pouch, potentially backflowing into the bladder.

[0009] The collection tube connection of the urobag is equipped with a vertical check valve (drip chamber), allowing urine to drip from the end of the collection tube into the urobag in small amounts.However, if the check valve is placed in a horizontal position, the backflow prevention function will not work properly, and urine will flow back from the urobag to the collection tube.

[0010] The check valve acts as a resistance component to urine collection, so to overcome this resistance and ensure smooth urination, it is necessary to make the height difference between the bladder and the urobag as large as possible. If the height difference between the bladder and the urobag is small, the above-mentioned negative pressure and discharge resistance will reduce the discharge ability, causing urine to accumulate in the collection tube or pouch. When turning over in bed while sleeping, the accumulated urine will flow back into the bladder, causing urinary tract infections.

[0011] Furthermore, the hanging urobag 51 using the hanging string 55 and S-hook 54 shown in Figure 8 has the disadvantage of being easily twisted. If the urobag 51 is twisted, the pouch connected via the collection tube 52 will also be twisted, blocking the urination path and causing the problem of urine that should be discharged accumulating in the pouch. If urine accumulates in the pouch due to this urinary tract obstruction, abdominal pressure, such as when the patient is in a lateral position, can cause reflux from the pouch into the bladder, leading to urinary tract infections.

[0012] Furthermore, urinary retention is thought to be a cause of edema by inhibiting the excretion of excess fluid from the body. It has been pointed out that edema caused by lack of exercise or aging can be improved by increasing urination volume, and diuretics are commonly administered intravenously during postoperative rest.

[0013] As described above, the conventional hanging urobag system has the risk of causing various health problems due to the small height difference between the bladder and urobag, but there is a limit to how much height difference can be increased with the hanging system. One possible solution to dramatically increase the height difference between the bladder and urobag and increase urine output would be to install the urobag horizontally on the floor. However, as mentioned above, horizontal installation poses the problem of urine accumulated in the urobag flowing back into the collection tube, making normal urine collection difficult.

[0014] In addition, there is the problem of urinary retention, where the pouch becomes twisted and blocks the urination pathway, so to solve this problem, a stable installation form that does not rotate the urobag itself is required.It is also desirable to expand the installation location by removing restrictions, for example, so that it can be installed on beds without handrail frames, and to make it portable so that it can be installed on wheelchairs, dining chairs, and sofas. [Means for solving the problem]

[0015] The present disclosure has been made in consideration of the above circumstances, and aims to provide a drainage bag storage device that reduces the height of the drainage bag while allowing a check valve provided on a collection tube connected to the drainage bag to operate normally.

[0016] In order to achieve the above object, the drainage bag storage device has the following configuration. A drainage bag storage device for storing a drainage bag connected via a collection tube to an artificial bladder pouch or an indwelling urinary catheter attached to a patient, the device comprising: a storage device main body that stores the drainage bag in a horizontal position on the inner bottom surface of a housing with an open top; and an L-shaped hook attached to the inner surface of the storage device main body, with its tip facing upward, at a height equivalent to the length of a check valve attached to the collection tube connected to the drainage bag; the storage device main body being installed on a floor surface or an installation surface aligned therewith; a handle hole or a ring-shaped hanging string attached to an end of the drainage bag being engaged with the L-shaped hook, the drainage bag being hung in an upright position with the check valve along the inner surface on which the L-shaped hook is attached, and the drainage bag is folded so as to be in a horizontal position directly below the check valve, and the drainage bag below the folded part is stored in a horizontal position along the inner bottom surface of the storage device main body. By installing the storage device main body containing the suspended drainage bag on the floor, the height difference between the bladder and the drainage bag can be dramatically increased to prevent backflow, promote urine discharge, and prevent twisting of the pouch. This allows for a drainage bag storage device that keeps the height of the drainage bag low while allowing the check valve on the collection tube connected to the drainage bag to function properly. This is expected to improve patients' quality of life by preventing urinary tract infections, poor urination (urinary retention), and edema.

[0017] A drainage bag storage device for storing a drainage bag connected via a collection tube to an artificial bladder pouch or an indwelling urinary catheter attached to a patient, the device comprising: a storage device main body for storing a drainage bag in a horizontal position on the inner bottom of a housing with an open top; a lid capable of closing the top of the storage device main body; an upright holding part for holding one side of the lid part in an upright position along the inner side while abutting the inner bottom of the storage device main body; an L-shaped hook on the closed surface of the lid part above the upright holding part for hanging a handle hole or a ring-shaped hanging string provided on an end of the drainage bag; and The main body may be provided with a long gripping hole provided near the side surface of the upright tip of the lid portion held in an upright position, and the upright holding portion may hold the lid portion in an upright position along the inner surface of the storage device main body, and a handle hole or a ring-shaped hanging string provided at an end of the drainage bag may be engaged with the L-shaped hook to hang the drainage bag in an upright position with the check valve along the closed surface of the lid portion on which the L-shaped hook is provided, and the drainage bag may be folded so as to be in a horizontal position directly below the check valve and stored in a horizontal position along the inner bottom of the storage device main body. This allows the lid to be fitted onto the top surface of the storage device body during transport or storage of the drainage bag, resulting in compact storage and reduced height, reducing transportation costs and storage space. Furthermore, when the lid is raised along the inner surface of the storage device body, the storage device body can be raised to any height by grasping the grip hole near the side of the rising tip of the lid. This eliminates floor-level work, reducing the workload on patients and nurses, and also allows the storage device body to be moved along with the drainage bag as the patient moves.

[0018] One or more grooves large enough to allow the collection tube to be inserted and removed from the outside may be provided on the side of the lid, which is held in an upright position on the storage device main body, and the collection tube, which extends from the check valve, which is in an upright position with the drainage bag hung from the L-shaped hook of the lid, toward the open upper surface of the storage device main body, may be engaged and guided in the grooves. This means that when the storage device main body is installed on the floor surface under the bed, the collection tube can be temporarily fastened to the recessed groove in the lid portion in the upright position, which prevents the collection tube from getting tangled around the patient's legs and also prevents excess collection tube from coming into contact with the floor surface. [Effects of the Invention]

[0019] By placing the storage device main body containing the suspended drainage bag on the floor, the height difference between the bladder and the drainage bag can be dramatically increased to prevent backflow, promote urine discharge, and prevent twisting of the pouch. This makes it possible to provide a drainage bag storage device that keeps the height of the drainage bag low while allowing the check valve on the collection tube connected to the drainage bag to operate normally. In this way, when the storage device main body with the drainage bag suspended is placed on the floor, the height difference between the bladder and the drainage bag increases, generating a strong suction force, promoting urination and improving swelling and joint pain. It also prevents backflow of urine from the pouch into the bladder, preventing urinary tract infections. It also reduces dissolution of the pouch faceplate adhesive, reducing urine leakage from the adhesive surface. Furthermore, because the drainage bag is held in place by the inner bottom surface of the storage device main body and the L-shaped hook, it stabilizes posture, prevents twisting of the pouch, and prevents urination problems (urinary retention), which is expected to improve the patient's quality of life (QOL).

DETAILED DESCRIPTION OF THE INVENTION

[0021] [Example 1] An embodiment of a drainage bag storage device according to the present disclosure will be described with reference to the drawings. The drainage bag storage device 1 hangs and stores a drainage bag 3 (urobag) connected to an artificial bladder pouch or an indwelling urinary catheter (not shown) attached to a patient via a collection tube 2. This device is versatile enough that any type of conventional urobag can be used as is and stored in the storage device main body 4 (tray) as long as the external dimensions are compatible.

[0022] 1, the storage device main body 4 stores the drainage bag 3 in a horizontal position in the inner bottom part 4a of the housing with an open top. An L-shaped hook 5 is attached to the inner surface 4b of the storage device main body 4 at a height equivalent to the length of the check valve 2a provided on the collection tube 2 connected to the drainage bag 3, with its bent tip facing upward. The L-shaped hook 5 is made of metal such as stainless steel and is fixed to the inner surface 4b of the tray by screws or adhesive. Alternatively, if the storage device main body 4 is made of plastic, it may be fixed by adhesive or molded as a single piece.

[0023] The storage device main body 4 is a rectangular parallelepiped with an open top and large enough to store a drainage bag 3 (urobag) in a horizontal position. It is made of a plastic material such as polypropylene, which provides waterproof and dustproof properties and makes it washable. The entire device is preferably white so that the color of urine accumulated inside the bag can be easily identified. A typical tray size is about A4, and the height when placed horizontally on the floor or a surface aligned with it is approximately 5 cm.

[0024] 2 shows the state in which the drainage bag 3 is suspended and stored in the storage device main body 4 of FIG. 1. The handle hole 3a (or a circular hanging string, not shown) provided at the end of the drainage bag 3 is engaged with the L-shaped hook 5, and the drainage bag 3 is suspended in an upright position with the check valve 2a aligned along the inner surface 4b on which the L-shaped hook 5 is provided. The drainage bag 3 is also bent 90 degrees so as to be horizontal directly below the check valve 2a, and the portion of the drainage bag 3 below the bent portion is stored in a horizontal position along the inner bottom 4a of the storage device main body 4. The drainage bag 3 is normally used in a suspended vertical position, but the urine collection bag portion located below the check valve 2a may be horizontal. Therefore, the drainage bag 3 is bent 90 degrees directly below the check valve 2a, and the urine collection bag portion 3b is stored in the storage device main body 4 in a horizontal position. The reason why the drainage bag 3 is bent into an L shape directly below the check valve 2a is to keep the height of the drainage bag 3 low. Furthermore, since the urine collection bag portion 3b of the drainage bag 3 is stored on the inner bottom surface 4a of the storage device main body 4, the discharge outlet 3c does not come into contact with the floor surface F, eliminating the risk of the discharge outlet 3c becoming infected with bacteria.

[0025] Next, check valve 2a is located at the transport end above drainage bag 3, and is suspended vertically along the transport end, following L-shaped hook 5 and the wall surface that forms inner surface 4b. The angle with inner bottom surface 4a is approximately 90° to 75° throughout the urine collection section's empty to full state, and check valve 2a operates normally throughout. In other words, even at the maximum urine volume, there is no backflow from drainage bag 3 (urine collection bag) to collection tube 2. The collection tube 2 is connected to check valve 2a, and is guided upward to connect to the pouch on the mattress top surface.

[0026] The drainage bag 3 (urine collection bag) below the check valve 2a is folded 90 degrees and stored horizontally against the tray's inner bottom surface 4a. The weight of the accumulated urine is applied to the tray's inner bottom surface 4a, so the position and angle of the check valve 2a are barely affected, and the check valve 2a maintains its vertical position regardless of the amount of accumulated urine. When the amount of accumulated urine approaches its limit, the drainage bag 3 expands into a circular shape, becoming roughly cylindrical when suspended, but when placed horizontally, the part in contact with the bottom surface flattens and becomes roughly semi-cylindrical. This slightly reduces the storage capacity, but because the maximum storage capacity of the drainage bag 3 (urobag) is ample, it rarely accumulates to its full capacity, presenting no practical problems.

[0027] As described above, by folding the drainage bag 3 into an L-shape directly below the check valve 2a and storing it in the storage device main body 4 (tray), the height of the drainage bag 3 from the floor is approximately 5 cm, which is the length of the check valve 2a. With the conventional hanging method shown in Figure 8, the drainage bag 3 required a hanging height of approximately 35 cm, and when the height from the floor to the top of the mattress was 40 cm, the drop between the bladder and the drainage bag 3 was only about 5 cm. With this proposal, the drop is significantly increased to 35 cm, generating a strong suction force on the drainage bag 3 side.

[0028] Next, we will discuss the health benefits of this disclosure. This proposal is effective in a wide range of areas, including medical, psychological, and hygienic benefits. First, by increasing the head, urine remaining in the collection tube 2 is smoothly drawn into the drainage bag 3 (urobag), preventing reflux into the bladder. This helps prevent urinary tract infections. Furthermore, gentle and effortless urination is promoted without relying on diuretics, which is also effective in reducing swelling and joint pain caused by swelling.

[0029] In addition, the drainage bag 3 (urobag) is stably fixed by the inner bottom surface 4a of the storage device main body 4 and the L-shaped hook 5, preventing twisting of the pouch and preventing urination problems (urinary retention) and urinary leakage. This also has the psychological effect of allowing the patient to turn over in bed and sleep with peace of mind, resulting in a comfortable sleep. Furthermore, because the drainage bag 3 is stored in the storage device main body 4 and isolated from the floor, dust and bacteria on the floor are prevented from adhering to the drainage bag 3. This prevents the drain outlet 3c (see Figure 2) of the drainage bag 3 from becoming contaminated with bacteria. The above effect can be verified simply by moving the drainage bag 3, which was hanging from the handrail frame of the bed, to the storage device main body 4 placed on the floor.

[0030] In this way, when the storage device main body 4 with the drainage bag 3 suspended and stored therein is placed on the floor, the height difference between the bladder and the drainage bag 3 is dramatically increased, preventing backflow, promoting urine discharge, and preventing twisting of the pouch. This is expected to improve the patient's quality of life by preventing urinary tract infections, poor urination (urinary retention), and suppressing edema.

[0031] [Example 2] In Example 2, a lid 6 for closing the top opening is newly provided separately from the storage device main body 4 shown in Example 1. The lid 6 is detachably attached to the inner surface 4b of the storage device main body 4, and an L-shaped hook 5 having the same shape as in Example 1 is provided on the back side of the lid 6 so as to be in the same position as in Example 1.

[0032] 3 is a perspective view of the storage device main body 4 with the lid 6 attached upright to the inner surface thereof, and FIG. 4 is a cross-sectional view of the storage device main body 4 of FIG. 3 with the drainage bag 3 stored therein in a suspended state. The easiest way to attach the lid 6 to the storage device main body 4 is to use two bolts, but here we will give another example. Two stepped bolts 4c (standing holding parts) protrude from the inner surface 4b of the storage device main body 4. The lid 6 has two elongated holes 6a at one longitudinal end, each slightly larger than the large-diameter shaft of the stepped bolts 4c, and at the other end, each slightly larger than the small-diameter shaft of the stepped bolts 4c. An L-shaped hook 5 is attached to the closed surface (inner surface of the lid) near the elongated holes 6a of the lid 6. A gripping hole 6b is provided at the other longitudinal end of the lid 6 (side of the standing tip).

[0033] When using the drainage bag storage device 1, the lid 6 is removed from the storage device main body 4, one longitudinal end is placed upright along the inner surface 4b, and the large-diameter shaft of the shoulder bolt 4c is inserted into the elongated hole 6a and slid to the right or left, whereby the small-diameter shaft engages with the elongated hole 6a and is assembled in an upright position. This allows the lid 6 to be attached and detached to and from the storage device main body 4 quickly without tools, eliminating the need for bolt and nut attachment and removal and storage work. The attachment method is not limited to the above two methods; the key is that the lid 6 can be easily attached in an upright position to the inner surface 4b of the storage device main body 4 and does not fall off.

[0034] As shown in FIG. 4 , the lid 6 is held in an upright position by the storage device main body 4. The handle hole 3a at the end of the drainage bag 3 is engaged with an L-shaped hook 5 facing upward on the inner surface of the lid, and the check valve 2a is aligned along the lid 6 on which the L-shaped hook 5 is attached, suspending the drainage bag 3 in an upright position. The drainage bag 3 is bent so as to assume a horizontal position directly below the check valve 2a and is stored in a horizontal position along the inner bottom 4a of the storage device main body 4. The angle of the check valve 2a connected to the drainage bag 3 relative to the inner bottom 4a is approximately 90° to 75° from the empty state to the full state of the urine collection bag 3b, and the check valve 2a operates normally throughout the entire range. Furthermore, by gripping the handle hole 6b on the lid 6, the storage device main body 4 can be lifted and moved together with the drainage bag 3 to any desired height.

[0035] Here, we will explain the advantages of attaching the lid 6 to the storage device main body 4 in an upright position. FIG. 5 shows the state in which the lid 6 is attached, covering the top opening of the storage device main body 4. By attaching the lid 6 to cover the top opening of the storage device main body 4, the height of the storage device main body 4 is reduced to approximately the height of the check valve 2a, reducing the transportation cost of the drainage bag storage device 1 and allowing it to be stored without taking up much space when used in large quantities in a hospital, etc. Furthermore, as shown in FIG. 4, when the lid 6 is attached upright along the inner surface 4b of the storage device main body 4, the storage device main body 4 can be raised to any height by grasping the gripping hole 6b near the side of the upright tip of the lid 6. This eliminates work at floor level, reducing the workload on patients and nurses, and also allows the storage device main body 4 to be moved together with the drainage bag 3 as the patient moves.

[0036] FIG. 6 is an explanatory diagram of the drainage bag storage device 1 with the lid 6 attached in an upright position to the inner surface 4b of the storage device main body 4, installed on the floor F under a bed. When the lid 6 is attached upright to the inner surface 4b with its longitudinal direction aligned vertically and the drainage bag storage device 1 is installed on the floor F under a bed, the height of the lid 6 allows the storage device main body 4 to be grasped by the gripping hole 6b and aligned with the bedside (frame 7 and mattress 8) to be sent under the bed. Since components such as the frame and motor often protrude from the bed bottom, the height of the storage device main body 4 must be as low as possible to avoid interference with these components. In this proposal, the height of the storage device main body 4 excluding the lid 6 can be set to approximately the height of the check valve 2a, making it compatible with a wider variety of beds and improving versatility. Furthermore, since the storage device main body 4 can be completely stored under the bed, it does not interfere with nurses' work and prevents patients from falling. Furthermore, providing a gripping hole 6b for transportation above the lid 6 allows it to be grasped at a higher position, improving workability and portability. In addition, the drainage bag 3 (urobag) can be attached and detached at waist level, avoiding the need to work at a low position on the floor.It can also be installed anywhere, does not require a bed handrail frame, and does not require the work of adjusting the height of the drainage bag 3 (urobag).

[0037] [Example 3] In Example 3, grooves 6c for temporarily securing collection tubes 2 are provided at opposing positions in the short direction of the lid 6 of Example 2 described above. The shape, position, and number of grooves can be modified as appropriate. Figure 7 is a front view of a modified example of a drainage bag storage device 1 in which grooves are provided in the lid 6. Multiple grooves 6c are provided on both sides of the lid 6, which is attached upright to the storage device main body 4. Note that grooves 6c may be provided on only one side of the lid 6 in the upright position. By inserting and holding a collection tube 2 into any of the grooves 6c while the lid 6 is attached upright to the inner surface 4b of the storage device main body 4, contact with the floor F is prevented, preventing the collection tube 2 from becoming tangled around the patient's feet and also preventing excess collection tube 2 from contacting the floor F.
