Description

Technical Field

[0001] The present disclosure relates to a suspension device for a medical drainage bag, such as a bag for accumulating urine collected by an artificial bladder device or a bag for accumulating body fluid collected by a catheter.

Background Art

[0002] In a hospital, blood, body fluid, urine, etc. in a patient's body after surgery are collected by a catheter and accumulated in a drainage bag by natural flow through a collection tube. The drainage bag is installed at a low position on the handrail frame of the bed. Specifically, it is suspended on the handrail frame using an S-shaped hook attached to the drainage bag and a thin string, a binding band, a rubber ring, etc. Since the accessories used for suspension are discarded together with the drainage bag in a short period, the manufacturer cannot afford the cost, resulting in a simple installation method lacking stability by the hook and string.

[0003] On the other hand, patients using an artificial bladder device at home connect and accumulate an additional urine storage bag (drainage bag) only during sleep at night. The installation method of the drainage bag is also the same simple method as the above hospital example. When waking up, the drainage bag is carried to the toilet with one hand and excreted from the drainage bag, and then the emptied drainage bag is washed and stored at the washbasin. These operations can be dangerous operations involving falls for the elderly or disabled. After getting out of bed, urine is stored in the artificial bladder device with a storage capacity of about one-tenth of the drainage bag, and the excretion cycle is 1 to 2 hours. Each time, the patient goes to the toilet and excretes from the artificial bladder device.

[0004] Here, the artificial bladder device will be briefly explained. The artificial bladder device is a urine storage bag that accumulates urine discharged from a urostoma, is adhered to the abdomen with a panel, and has a discharge valve that can be connected to a collection tube. When the drainage bag is not used, the discharge valve is closed and urine is stored in the artificial bladder device. When the drainage bag is used, the discharge valve is opened and urine is stored in the drainage bag by natural flow, and the artificial bladder device is in an empty state as it does not store urine.

[0005] Figure 10 is a front view of the drainage bag for the artificial bladder device, and Figure 11 is a right side view of Figure 10. During sleep or rest, the drainage bag P is connected to the artificial bladder device 50 (see Figure 12) to collect urine. The drainage bag P is a large-capacity plastic bag (cavity) with a size of approximately 300 mm square and a capacity of about 2.5 liters, allowing for long-term urine storage during sleep, etc. One side is transparent to observe the urine color and has a horizontal scale printed on it to measure the amount of urine collected. The other side is white and opaque, serving as an observation horizon. A long hole 51 for carrying is provided at the top of the drainage bag, forming a handle, and a check valve 52 is provided on the upstream side and a discharge valve 53 on the downstream side.

[0006] There are two types of attachment positions for the collection tube T: a side tube type, which is attached to the right or left end of the drainage bag, and a center tube type, which is attached to the center of the drainage bag. Figure 10 shows an example of the side tube type. In addition, there are two types of suspension methods: one that uses the transport slot 51 provided in the drainage bag P, and another that uses the suspension string attached to the drainage bag P.

[0007] Figure 12 shows an example of use by a patient with a drainage bag P connected to the artificial bladder device 50. Patient K has an artificial bladder device 50 attached to his abdomen, to which a drainage bag P is connected via a collection tube T. The drainage bag P is suspended from the horizontal frame 54a of the bed's handrail frame 54 using an S-hook and a hanging string 55, and the cavity of the drainage bag P is positioned sufficiently lower than the top surface of the mattress M to allow for urine collection. Urine, which is intermittently discharged little by little from the urostomy in patient K's artificial bladder device 50, is collected in the drainage bag P via the collection tube T. When a predetermined amount has been collected, the artificial bladder device 50 and the collection tube T are disconnected, and the urine collected in the drainage bag P is excreted in the toilet.

[0008] Prior art documents related to suspension devices for medical drainage bags include a urine collection bag that facilitates attachment and detachment to a bed frame (Patent Document 1: Japanese Patent Publication No. 2009-66228). Examples include a urine collection bag hanging and holding device that improves the visibility of urine collection bags attached to and detached at the bedside (see Patent Document 2: Japanese Patent Publication No. 2010-17524), an intravenous drip stand that suspends and supports infusion packs (see Patent Document 3: Japanese Patent Publication No. 2016-16215), and a medical bag attachment device for wheelchairs (see Patent Document 4: Japanese Patent Publication No. 2020-168346). [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Japanese Patent Publication No. 2009-66228 [Patent Document 2] Japanese Patent Publication No. 2010-17524 [Patent Document 3] Japanese Patent Publication No. 2016-16215 [Patent Document 4] Japanese Patent Publication No. 2020-168346 [Overview of the project] [Problems that the invention aims to solve]

[0010] As mentioned above, since the catheter (not shown) or artificial bladder device 50 has little capacity to store drainage fluid, a collection tube T must be connected and an external drainage bag P must be provided. In a hospital, patient K is in bed all day, so the location where the drainage bag P can be placed is limited to the bed. On the other hand, patient K who is fitted with an artificial bladder device 50 at home is able to get out of bed and walk around, so the drainage bag P is used in a wide range of places, including throughout the house and even while traveling, and it is necessary to transport the drainage bag P while it is still connected to the artificial bladder device 50. However, currently, the drainage bag P is designed with the assumption of use in bed, and portability is hardly considered. As a result, patient K who is fitted with an artificial bladder device 50 only uses the drainage bag P while sleeping, and after getting out of bed, it is disconnected and relies on the artificial bladder device 50, which has little storage capacity, to store urine. Therefore, there are various challenges for home-based patient K who is fitted with an artificial bladder device 50.

[0011] First, the need to frequently drain the fluid accumulated in the artificial bladder device 50 creates time constraints on daily activities, leading to a decrease in quality of life (QOL). Furthermore, the time and expense of disinfecting the drain valve 53 of the artificial bladder device 50 each time it is drained is incurred. Additionally, there are issues such as the risk of the artificial bladder device 50 rupturing due to compression by the seatbelt while the patient is seated. Furthermore, when transporting the artificial bladder device 50 while it is connected to the drainage bag P via the collection tube T, the excess portion of the collection tube T may hinder walking or rehabilitation, and if the collection tube T twists, it may block the drainage path of the artificial bladder device 50. In addition, when detaching the collection tube T from the artificial bladder device 50, there are usability issues such as leakage if there is no means to hold the tip of the collection tube T.

[0012] The root cause of these problems lies in the simplistic methods used to suspend the drainage bag P and align the collection tube T. Furthermore, the transportation of the drainage bag P to locations away from the bed has been largely neglected. With the number of patients increasing daily, resolving these issues is urgent. Home-care patients K require a portable device that allows for continuous use of the drainage bag P even during the day. For hospital use, a robust suspension device that can be used for extended periods rather than being disposable is desirable, and this is expected to reduce the cost of the drainage bag P and contribute to the SDGs.

[0013] Regarding prior art documents related to medical drainage bags, Patent Document 1 integrates a handrail hook into the drainage bag and is intended for use only on bed railings, and does not provide portability for patients leaving their beds. Patent Document 2 involves securing a frame with a shielding bag to the bed railing with a belt, and is also intended for use on bed railings, and does not provide portability for patients leaving their beds. Patent Document 3 expands the use of drainage bags to IV stands, but IV stands are not suitable for general households. Patent Document 4 provides a drainage bag attachment for wheelchairs, and is therefore only usable by wheelchair users. [Means for solving the problem]

[0014] This disclosure provides a medical drainage bag suspension device that can be attached to either the bed handrail frame or the waist belt, improving the quality of life (QOL) by increasing the portability of the drainage bag by the patient. Furthermore, the present invention provides a medical drainage bag suspension device that prevents the drainage bag from falling off, tilting, or rotating when suspended by a transport slot or suspension string, and prevents twisting of the collection tube by integrating and aligning the excess portion of the collection tube connected to the catheter or artificial bladder device with the drainage bag, thereby improving the ease of use for the patient and not hindering walking or rehabilitation.

[0015] To solve the above-mentioned problems, the embodiment includes the following configuration. A medical drainage bag suspension device for use in which a drainage bag connected to a catheter or artificial bladder device attached to a patient by a collection tube is attached to the handrail frame of a bed or a waist belt worn by the patient, comprising: a pair of annular frames having a gate portion on a part of the annular frame that can be opened and closed toward an annular hole; a suspension portion connecting the pair of annular frames by a connecting member in a facing position with the annular holes facing each other; and a locking portion extending in a direction intersecting the connecting member so as to be spaced apart from the pair of annular frames and capable of being locked to the handrail frame or the waist belt, wherein the transport hole or suspension string of the drainage bag is suspended and supported by opening the gate portions of the pair of annular frames of the suspension portion, and the excess portion of the collection tube connected to the drainage bag is routed around and guided into the annular hole to be aligned and held.

[0016] This allows the locking mechanism to be easily attached to either the handrail frame or the waist belt, improving the portability of the drainage bag by the patient. This makes it usable regardless of whether the patient is hospitalized or outpatient, and regardless of whether it is day or night, eliminating the hassle of managing excretion and improving quality of life. Furthermore, by using a suspension section in which a pair of annular frames are connected by a connecting member while their annular holes face each other, and by suspending the drainage bag using a transport slot or hanging string by opening the gate sections of the pair of annular frames and supporting it at two points, it is possible to prevent the drainage bag from falling off, tilting, or rotating, thereby improving ease of use. Furthermore, the excess portion of the collection tube connected to the drainage bag can be routed around and guided into the annular hole of the suspension section, allowing it to be integrated with the drainage bag and held in place. This prevents the collection tube from twisting, does not hinder walking or rehabilitation after getting out of bed, and improves ease of use.

[0017] If the connecting member is provided with a tube holder that holds the tip opening of the collection tube connected to the drainage bag facing upward, when detaching the collection tube from the catheter or artificial bladder device in bed, or when washing and drying the drainage bag, the detached tip opening of the collection tube can be held upward in the tube holder to prevent leakage.

[0018] The aforementioned annular frame uses a D-shaped frame, with the annular straight sections connected by connecting members, and a gate section that opens and closes toward the annular hole is provided on a part of the annular curved section. By opening the gate sections on the pair of annular curved sections and suspending the drainage bag with a transport slot or hanging string via the gate section, the drainage bag can be prevented from falling, tilting, or rotating, improving ease of use. Furthermore, the excess portion of the collection tube connected to the drainage bag can be routed around and guided into the annular hole of the annular curved section, allowing it to be integrated with the drainage bag and held in alignment.

[0019] The locking portion may be a pair of U-shaped hooks connected to both ends of the connecting member, with arm portions extending in a direction away from the annular frame, or a flat U-shaped hook connected to the connecting member, with arm portions extending in a direction away from the annular frame. This makes it easy to replace the locking part with either the handrail frame of the bed or the waist belt, and the folded-back part of the U-shaped hook makes it difficult to fall off. The hanging posture of the drainage bag is stabilized by a pair of U-shaped hooks or flat U-shaped hooks. In particular, by attaching it to the lowest horizontal frame with a low height among the handrail frames of the bed, the distance from the upper surface of the mattress to the drainage bag can be ensured, and the drainage flow-down characteristics can be maintained.

[0020] The annular frame is an S-shaped frame in which annular curved parts are continuous, and gate parts that open and close toward the annular hole are provided in a part of the continuous annular curved parts. The pair of annular frames may be connected by a connecting member with the annular holes facing each other in an opposing posture. This makes it easy to replace the gate of the upper annular curved part with either the handrail frame of the bed or the waist belt, and since it is locked by two-point support by the pair of annular curved parts, the hanging posture of the drainage bag is stabilized. Also, by the lower annular curved part, by opening the gate part provided in the pair of annular curved parts for the long hole or suspension string for transporting the drainage bag through the gate part and hanging it by two-point support, it is possible to prevent the drainage bag from falling off, tilting, and rotating, improve the usability, and also wind up the surplus of the collection tube connected to the drainage bag and guide it to the annular hole of the annular curved part to be integrated with the drainage bag and aligned and held.

Effects of the Invention

[0021] The locking part can be replaced with either the handrail frame of the bed or the waist belt, and it is possible to provide a hanging device for a medical drainage bag that improves the QOL by enhancing the portability of the drainage bag by the patient. In particular, it is possible to provide a hanging device for a medical drainage bag that prevents the drainage bag suspended by a pair of annular curved parts by a long hole or suspension string for transportation from falling off, tilting, and rotating, and prevents the twisting of the collection tube by integrating and aligning and holding the surplus of the collection tube connected to the catheter or artificial bladder device with the drainage bag, and improves the usability of the patient without interfering with walking or rehabilitation.

[Figure 12] This is an explanatory diagram showing an example of use where a drainage bag is connected to a typical artificial bladder device. [Modes for carrying out the invention]

[0023] The following describes in detail a suspension device for a medical drainage bag, which is attached to a catheter or artificial bladder device fitted to the patient via a collection tube, and then attached to the bed rail frame (horizontal frame) or the waist belt worn by the patient.

[0024] [Example 1] Figure 1 is a perspective view of the suspension device 1 for a medical drainage bag, and Figure 2 is a right side view of the same suspension device 1 shown in Figure 1. Figure 2 also shows the surrounding components to be attached, with arrows indicating the direction of attachment of the surrounding components, and the gate indicating the open state.

[0025] The medical drainage bag suspension device 1 comprises a suspension section 1X formed by connecting a pair of annular frames 1A and 1B with a pair of connecting members 1c and 1d, while the annular holes 1a and 1b face each other in an opposing position, and a locking section 1Y that extends in a direction intersecting (orthogonal) to the connecting members 1c and 1d so as to be spaced apart from the pair of annular frames 1A and 1B, and can be locked to a handrail frame F or waist belt B (see Figure 2).

[0026] The annular frame 1A has a gate portion 1e that can be opened and closed toward the annular hole 1a. The annular frame 1B has a gate portion 1f that can be opened and closed toward the annular hole 1b. The transport slot or hanging string of the drainage bag P is suspended and supported by opening the gate portions 1e and 1f of the pair of annular frames 1A and 1B of the suspension section 1X, and the collection tube T connected to the drainage bag P is guided into the annular holes 1a and 1b and held in alignment (see Figure 2).

[0027] The configuration of each part will be explained in detail below. In Figure 1, the suspension section 1X uses a pair of annular frames 1A and 1B, for example, a pair of D-shaped frames. The annular frame 1A has an annular straight section 1g and an annular curved section 1i connected thereto. A gate section 1e that opens and closes toward the annular hole 1a is provided on a part of the annular curved section 1i. The annular frame 1B has an annular straight section 1h and an annular curved section 1j connected thereto. A gate section 1f that opens and closes toward the annular hole 1b is provided on a part of the annular curved section 1j. The gate sections 1e and 1f are normally closed (annular state) by, for example, a torsion coil spring, and can be opened manually toward the annular holes 1a and 1b at will. The pair of D-shaped frames are connected at their upper and lower ends by a pair of connecting members 1c and 1d, respectively, with the annular straight sections 1g and 1h (body-side frames) facing each other in an opposing position with the annular holes 1a and 1b facing each other. Thus, since nothing is provided between the annular curved sections 1i and 1j, which are the non-body-side frames, and not between the annular straight sections 1g and 1h, which are the body-side frames, a space is left open, even a center tube type drainage bag P (see Figure 9) can be suspended without interfering with the collection tube T.

[0028] As shown in Figure 2, the gates 1e and 1f provided on the anti-body frame (annular curved section 1i, 1j), which is located in the opposite direction from the body-side frame (annular straight section 1g, 1h) of the pair of annular frames 1A and 1B, can be opened to secure the elongated hole or hanging string for transporting the drainage bag P, or to guide the collection tube T into the annular holes 1a and 1b via the gates 1e and 1f. Thus, the pair of annular frames 1A and 1B constitute a suspension section 1X that combines a hook function to suspend the drainage bag P horizontally without it falling off, and a tube clamp function to hold the excess portion of the collection tube T in an aligned position. The annular frames 1A and 1B have no protrusions, enhancing safety by not interfering with the patient's body when they are walking, etc.

[0029] The gate sections 1e and 1f are always closed except for moments such as when attaching or detaching the collection tube T, so the drainage bag P passed through the annular holes 1a and 1b will not fall, ensuring high reliability. Furthermore, the drainage bag P is supported at two points by a pair of annular curved sections 1i and 1j and is suspended horizontally and stably. Additionally, by circling the excess portion of the collection tube T and aligning and holding it within the annular holes 1a and 1b, it becomes possible to rotate the patient's body, and the length of the collection tube T can be adjusted while holding the drainage bag P. Note that the annular frames 1A and 1B constituting the suspension section 1X are not limited to D-shaped frames; O-shaped, pear-shaped, or other shapes are also possible as long as they can be formed in an annular shape.

[0030] In Figure 2, the locking portion 1Y is, for example, a pair of U-shaped hooks 1k. Specifically, the arm portions extend from both ends of the upper connecting member 1c in a direction perpendicular to the annular frames 1A and 1B (towards the body) by the diameter of the handrail frame F (horizontal frame) plus the thickness of the waist belt B. The pair of arm portions extend vertically downward from there to a height greater than that of the waist belt B, and further have a folded portion 1k1 that is folded back by the thickness of the waist belt B in a direction closer to the annular frames 1A and 1B (against the body), forming an overall U-shape. By providing the folded portion 1k1 in this way, the waist belt B catches on the hook when attached to the waist belt B, preventing the suspension device from falling. The U-shaped hooks 1k are made of solid cylinders to ensure safety and reduce weight, and can be easily attached to and detached from either the handrail frame F or the waist belt B worn by the patient. Furthermore, the folded-over portions 1k1 of the U-shaped hooks 1k, each with arms extending from both ends of the connecting member 1c, may be connected or separated, as in this embodiment.

[0031] As a specific example, since the outer diameter of the handrail frame F is uniformly φ19mm, the thickness of the waist belt B is set to 5mm, and the depth of the U-shaped hook 1k is set to 24mm. The height of the U-shaped hook 1k is set to 40mm, which is greater than or equal to the height of the waist belt B. In order for the waist belt B to hang stably, the corner of the L-shape is set to 90°, and the folded length is set to 5mm. The width must be less than or equal to the width of the elongated hole for transporting the drainage bag P. These conditions make it possible to create a U-shaped hook 1k that can be easily attached to either the handrail frame F or the waist belt B. If the suspension part 1X is made of aluminum alloy, the weight is about 100g, the suspension strength of the D-shaped frame is 2 tons, and the expected maximum static load is about 3kgf, which is sufficient strength.

[0032] [Example 2] Next, Example 2 of the suspension device 1 for medical drainage bags will be described with reference to Figure 3. The same numbers will be used to refer to the same components as in Example 1. In Example 2, the suspension device 1X of the medical drainage bag suspension device 1 is the same as in Example 1, but the configuration of the locking part 1Y is different. That is, in Figure 3, the locking part 1Y may be a flat U-shaped hook 1k that extends away from the annular frames 1A, 1B in a direction that intersects (orthogonal to) the upper connecting member 1c of the pair of upper and lower connecting members 1c, 1d. The U-shaped hook 1k has a folded portion 1k1 that is folded back by the thickness of the waist belt B in a direction that is close to the annular frames 1A, 1B (anti-body direction), similar to Example 1. The U-shaped hook 1k is easy to attach to either the handrail frame F (horizontal frame) or the patient's waist belt B, and the folded portion 1k1 of the U-shaped hook 1k makes it difficult to detach, and the flat plate provides a secure hold, stabilizing the hanging position of the drainage bag P.

[0033] [Example 3] Next, an embodiment 3 of the medical drainage bag suspension device 1 will be described with reference to Figure 4. Figure 4 is a perspective view of the medical drainage bag suspension device 1. The annular frame 1A uses an S-shaped frame in which an upper annular curved section 1i1 (locking section 1Y) and a lower annular curved section 1i2 (suspension section 1X) are continuously provided. The annular frame 1B also uses an S-shaped frame in which an upper annular curved section 1j1 (locking section 1Y) and a lower annular curved section 1j2 (suspension section 1X) are continuously provided. Furthermore, a gate portion 1e1 that opens and closes toward the annular hole 1a1 is provided on a part of the upper annular curved portion 1i1 of the annular frame 1A. A gate portion 1e2 that opens and closes toward the annular hole 1a2 is provided on a part of the lower annular curved portion 1i2. Furthermore, a gate portion 1f1 that opens and closes toward the annular hole 1b1 is provided on a part of the upper annular curved portion 1j1 of the annular frame 1B. A gate portion 1f2 that opens and closes toward the annular hole 1b2 is provided on a part of the lower annular curved portion 1j2. A pair of annular frames 1A and 1B are connected by a connecting member 1c at the upper annular curved sections 1i1 and 1j1, and by a connecting member 1d at the lower annular curved sections 1i2 and 1j2, while maintaining an opposing orientation with the annular holes 1a1 and 1b1 and annular holes 1a2 and 1b2 facing each other. The pair of connecting members 1c and 1d are provided on the body side, and a space is provided between the pair of annular frames 1A and 1B. As a result, a center tube type drainage bag P can be suspended from the lower annular curved sections 1i2 and 1j2 without interfering with the collection tube T (see Figure 9).

[0034] The gate sections 1e1 and 1f1 of the upper annular curved sections 1i1 and 1j1 can be opened to easily switch between attaching to the handrail frame F or the waist belt B. The pair of annular curved sections 1i1 and 1j1 provide two-point support for securing the drainage bag P, thus stabilizing its suspension position. In particular, since the gate sections 1e1 and 1f1 remain closed except during attachment and detachment, the suspension device can be prevented from falling, ensuring high reliability. Furthermore, by opening the gate sections 1e2 and 1f2 provided in the lower annular curved sections 1i2 and 1j2, and suspending the drainage bag P from the pair of annular curved sections 1i2 and 1j2 using a transport slot or hanging string with two-point support, it is possible to prevent the drainage bag P from falling off, tilting, or rotating, thereby improving ease of use. Also, by opening the gate sections 1e2 and 1f2 and guiding the excess portion of the collection tube T around into the annular holes 1a2 and 1b2, it is possible to align and hold it together with the drainage bag P. Furthermore, by constructing the pair of annular frames 1A and 1B from S-shaped frames, it becomes unnecessary to form the suspension portion 1X and the locking portion 1Y from separate components, as in Examples 1 and 2. Also, the gate portions 1e1 and 1f1 of the locking portion 1Y may be omitted.

[0035] [Example 4] Next, Embodiment 4 of the medical drainage bag suspension device 1 will be described with reference to Figure 5. Figure 5 is a perspective view of the medical drainage bag suspension device 1 according to Embodiment 1 shown in Figure 1, with the addition of a tube holder 2. The same numbers will be used to refer to the same components as in Embodiment 1. The medical drainage bag suspension device 1 according to Embodiment 4 has the same configuration as in Embodiment 1, comprising a suspension section 1X formed by connecting a pair of connecting members 1c and 1d with a pair of annular frames 1A and 1B facing each other in an opposing position with annular holes 1a and 1b facing each other, and a locking section 1Y that extends from the pair of annular frames 1A and 1B, intersecting (orthogonal to) the connecting members 1c and 1d, and can be locked to a handrail frame F or waist belt B (see Figure 2).

[0036] When detaching the catheter or artificial bladder device from the collection tube T while the patient is in bed, a function was needed to hold the tip opening of the collection tube T upwards once it had been detached. Therefore, a holding function was added to the suspension device 1 for the medical drainage bag, and a tube holder 2 that holds the tip opening of the collection tube T upwards was provided on the connecting member 1c. When holding the tip of the detached collection tube T, lightly pushing it into the groove 2a of the tube holder 2 causes the tube holder 2 or the collection tube T to deform and generate holding force. Furthermore, there was a need for a function that would allow the tip opening of the detached collection tube T to be stored facing upwards even after washing the drainage bag P. Using the tube holder 2 makes it possible to hold the tip opening of the collection tube T facing upwards. Therefore, when detaching the collection tube T from a catheter or artificial bladder device while in bed, or when washing and drying the drainage bag P, holding the detached tip opening of the collection tube T upward in the tube holder 2 prevents dripping.

[0037] Here, an example of using the medical drainage bag suspension device 1 according to Example 4 will be specifically described with reference to Figures 6 to 9. Figure 6 shows the state in which the drainage bag P for the artificial bladder device is suspended from the lowest handrail frame F (horizontal frame). The patient is lying supine on a mattress M (not shown) and has an artificial bladder device 3 attached to their abdomen. The artificial bladder device 3 is connected to the drainage bag P by a collection tube T. The drainage bag P is suspended from the handrail frame F by the medical drainage bag suspension device 1 and is installed at a position lower than the top surface of the mattress M, so that urine is collected by natural flow. While sleeping, the patient collects urine in the drainage bag P, and when waking up, the patient removes the medical drainage bag suspension device 1 along with the drainage bag P from the handrail frame F and attaches it to a waist belt B that they are wearing. This operation can be performed instantly by the patient while they are sitting on the bed, and they can safely get out of bed using both hands.

[0038] Figure 7 shows the drainage bag P for the artificial bladder device suspended from the waist belt B when the patient is out of bed. The suspension device is attached to the waist belt B by a locking part 1Y, and the drainage bag P is suspended below by a suspension part 1X. If the excess portion of the collection tube T is routed around the suspension part 1X and held in place, it can be stored without being bulkier than the drainage bag P, and the collection tube T will not get in the way when walking or sitting in a chair. Also, both hands are free, so daily activities such as washing, eating, or resting can be performed smoothly and safely. The suspension part 1X has a D-shaped frame and no open parts, so the drainage bag P will not fall off even when the patient exercises or works, providing peace of mind.

[0039] Figure 8 shows an example of storing the drainage bag P after washing it with water. It is suspended from a pipe shelf 4, and the tip opening of the collection tube T is facing upwards and stored in the tube holder 2 of the suspension device 1. The drainage bag P can be stored compactly and hygienically without dripping. Furthermore, if the drainage bag P is empty after excretion, it can be efficiently washed and dried by pouring water into the tip opening of the collection tube T while it is still suspended in the sink and draining the water from the discharge valve of the drainage bag P.

[0040] Figure 9 shows a drainage bag P connected to a catheter 6 via a collection tube T, suspended from the bed's handrail frame F (horizontal frame). In this example, the drainage bag P is a center tube type with a hanging string. The hanging section 1X has a gap in the center connecting the annular frames 1A and 1B, allowing the collection tube T to pass upwards, and it can be used without any problems. The hanging string 5 enters the annular holes 1a and 1b by opening the gate sections 1e and 1f of the D-shaped frame and is secured to the annular curved sections 1i and 1j (see Figure 2), so even a thin string can be securely suspended without falling.

[0041] As explained above, the medical drainage bag suspension device 1 allows the locking part 1Y to be attached to either the handrail frame F or the waist belt B, thereby increasing the portability of the drainage bag P by the patient, making it usable day or night, eliminating the hassle of dealing with excretion, and improving the quality of life. Furthermore, by using a suspension section 1X, which connects a pair of annular frames 1A and 1B with connecting members 1c and 1d while the annular holes 1a and 1b face each other, and suspending the drainage bag P using its transport slot or suspension string by opening the gate sections 1e and 1f of the pair of annular frames 1A and 1B with two-point support, it is possible to prevent the drainage bag P from falling off, tilting, or rotating, thereby improving ease of use. Furthermore, the excess portion of the collection tube T connected to the drainage bag P can be routed around and guided into the annular holes 1a and 1b of the annular frames 1A and 1B, allowing it to be integrated with the drainage bag P and held in alignment. This prevents twisting of the collection tube T, does not hinder walking or rehabilitation after getting out of bed, and improves ease of use. [Explanation of symbols]
