Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a drainage bag for gastroenterology with an anti-detachment structure. Background Technology

[0002] In the clinical diagnosis and treatment of gastroenterology, drainage bags are often used to collect accumulated fluid, gastrointestinal fluid, or other fluids from patients. Existing drainage bags typically consist of a bag body, a drainage tube, and a suspension structure attached to the bag body. In use, the drainage bag is usually suspended from bed rails, support beams, or other nursing support structures using ordinary hooks.

[0003] However, in actual use, the diameter, cross-sectional shape, and installation position of the bed rail crossbars and support crossbars are not entirely consistent, making it difficult for fixed-size open hooks to simultaneously accommodate crossbars of different specifications. When the crossbar diameter is small, a large gap can easily form between the hook and the crossbar, causing the bag to swing, slip laterally, or even jump off when the patient turns over, the bed rails are raised or lowered, caregivers move the bed, or the fluid inside the bag sloshes. When the crossbar diameter is large, ordinary hooks may have problems such as difficulty in attaching, insufficient attachment depth, or unstable force.

[0004] Furthermore, the open hook itself has an exit path, making the drainage bag prone to detaching from the crossbar when subjected to external force or sudden lifting, affecting drainage stability and safety. Although some drainage bags improve suspension adaptability by extending the hanging strap or adding hanging holes, they usually only achieve simple hooking and lack a reliable closed-loop locking structure, making it difficult to achieve anti-detachment, anti-shaking, and anti-slip effects while adjusting the enclosure size.

[0005] Therefore, it is necessary to provide a drainage bag for gastroenterology with an anti-detachment structure that can adapt to crossbars of different specifications and form a stable closed state after suspension. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage bag for gastroenterology with an anti-detachment structure, so as to solve the problem that existing drainage bags are prone to shaking, lateral slippage or falling off due to mismatched crossbar specifications when suspended by ordinary open hooks.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A drainage bag for gastroenterology with an anti-detachment structure includes a bag body, a drainage tube communicating with the bag body, and a reinforcing plate set at the upper end of the bag body; a hanging strap is connected to the reinforcing plate, the hanging strap has multiple adjustment slots along its length, and a locking mechanism is provided on the reinforcing plate. The hanging strap can pass around the crossbar and lock with the locking mechanism through any adjustment slot to form a closed suspension ring with different enclosure sizes.

[0008] By adopting the above technical solution, the hanging strap can cooperate with the locking mechanism to form a closed suspension ring after passing around the crossbar, thereby eliminating the exit path of ordinary open hooks; at the same time, multiple adjustment ports can form different enclosure sizes, so that the drainage bag can be adapted to crossbars of different diameters or shapes, improving suspension stability and reducing the risk of bag shaking, lateral slippage and jumping off.

[0009] Furthermore, the reinforcing plate has a slot for the hanging strap to pass through. One end of the hanging strap is fixedly connected to the reinforcing plate, and the other end is a free end that can be pulled out through the slot. Multiple adjustment stops are spaced apart along the length of the free end.

[0010] By adopting the above technical solution, the strap can be pulled out from the reinforcing plate and pass around the crossbar. Then, the corresponding adjustment stop can be selected according to the actual size of the crossbar to lock it, making the adjustment operation of the strap more convenient and helping to maintain the connection stability between the strap and the reinforcing plate.

[0011] Furthermore, the side of the hanging strap facing the crossbar is provided with multiple anti-slip ribs, which are spaced apart along the length of the hanging strap. The anti-slip ribs are used to abut against the surface of the crossbar when the hanging strap forms a closed suspension ring.

[0012] By adopting the above technical solution, when the strap is tightened and surrounds the outer perimeter of the crossbar, the anti-slip ribs can increase the contact resistance between the strap and the crossbar, thereby reducing the lateral slippage or swinging of the bag along the crossbar direction.

[0013] Furthermore, the anti-slip ribs are provided with suction cup openings on the side facing the crossbar, which are used to adhere to the surface of the crossbar when the strap is attached to it.

[0014] By adopting the above technical solution, the suction cup opening can form a certain adsorption effect when the strap is attached to the surface of the crossbar, further improving the adhesion stability between the strap and the crossbar and enhancing the anti-slip, anti-shaking and anti-detachment effects.

[0015] Furthermore, the reinforcing plate is equipped with a chuck, and a telescopic seat can also be telescopically connected to the reinforcing plate. The telescopic seat has a locking ball at one end facing the chuck; the chuck has a slot on the side facing the locking ball. The telescopic seat can drive the locking ball closer to the chuck, so that the locking ball is embedded in the slot, and the corresponding adjustment position is limited between the chuck and the locking ball; the telescopic seat can also drive the locking ball away from the chuck to release the limitation on the adjustment position.

[0016] By adopting the above technical solution, the locking ball, driven by the telescopic seat, can cooperate with the clamp to hold and limit the adjustment stop on the strap, so that the strap remains locked under the selected enclosure size; when disassembly or readjustment is required, the telescopic seat can release the limit by moving the locking ball away from the clamp, which is simple to operate and has a compact structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features an adjustable hanging strap and locking mechanism at the upper reinforcing plate of the bag body. The strap, after wrapping around the crossbar, forms a closed suspension loop. Different adjustment stops allow for adjustable enclosure sizes, thus adapting to different specifications of bed rail crossbars or support crossbars. Compared to ordinary open hooks, this structure reduces the risk of the hook coming loose and minimizes problems such as loosening, wobbling, tilting, and lateral slippage caused by mismatched crossbar specifications.

[0018] Meanwhile, the anti-slip ribs and suction cup on the strap enhance the contact stability between the strap and the crossbar, further improving the anti-slip, anti-shaking, and anti-slip effects after suspension. The locking ball, clamp, and telescopic seat form a releasable locking engagement, allowing the adjustment range to be reliably limited, balancing adjustment convenience and locking stability. The overall structure is simple and suitable for use in gastroenterology clinical drainage scenarios. Attached Figure Description

[0020] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application.

[0021] like Figures 1 to 4As shown, this embodiment provides a drainage bag for gastroenterology with an anti-detachment structure, comprising a bag body 1, a drain valve 11, a drainage tube 2, a needle 21, a stop clamp 3, a reinforcing plate 4, a hanging strap 5, and a locking mechanism 6. The bag body 1 is used to collect fluid generated during clinical drainage in gastroenterology. The bag body 1 can be made of flexible, transparent medical plastic material to allow nursing staff to observe the color, volume, and sedimentation state of the fluid inside the bag body 1. A drain valve 11 is installed at the lower part of the bag body 1 to drain the fluid after it reaches a certain volume, avoiding repeated replacement of the bag body 1. The upper part of the bag body 1 is connected to the drainage tube 2. A needle 21 or other drainage connector is installed at the end of the drainage tube 2 away from the bag body 1 for connection to the drainage site or corresponding medical tubing in the patient. A stop clamp 3 is installed on the drainage tube 2 to clamp or open the drainage tube 2, thereby controlling the flow of fluid.

[0022] A reinforcing plate 4 is provided at the upper end of the bag body 1. The reinforcing plate 4 is preferably a strip-shaped plate with a certain rigidity. The reinforcing plate 4 can be connected to the upper end of the bag body 1 by hot pressing, bonding, welding, or wrapping. Since the bag body 1 itself is a flexible film structure, when liquid gradually accumulates inside the bag body 1, the upper end of the bag body 1 will be subjected to a large pulling force. If the hanging structure is directly connected to the flexible film of the bag body 1, it is easy to cause local stress concentration at the upper end of the bag body 1, resulting in deformation, tearing, or unstable suspension. In this embodiment, by providing a reinforcing plate 4 at the upper end of the bag body 1, the weight of the bag body 1 and the weight of the liquid inside the bag body 1 can be transferred to the reinforcing plate 4 first, and then transferred from the reinforcing plate 4 to the hanging strap 5 and the crossbar, thereby improving the stress state at the upper end of the bag body 1 and improving the suspension reliability.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a hanging strap 5 is connected to the reinforcing plate 4. The hanging strap 5 is a flexible strip structure and can be made of medical-grade plastic, rubber, silicone, or other materials with a certain degree of flexibility and tensile strength. The hanging strap 5 can wrap around the outer perimeter of the bed rail crossbar, infusion stand crossbar, or other clinical support rods, and after wrapping around the crossbar, it cooperates with the locking mechanism 6 to form a closed suspension ring. The so-called closed suspension ring means that after the hanging strap 5 wraps around the crossbar, its free end is limited by the locking mechanism 6, so that the hanging strap 5 is no longer in a normal open hook-like open state, but forms a relatively closed enclosure structure around the crossbar. This structure can effectively reduce the possibility of the drainage bag falling off the crossbar when it is lifted, shaken, or laterally impacted.

[0024] The hanging strap 5 has multiple adjustable stops 52 along its length. These adjustable stops 52 are spaced apart at the free end of the hanging strap 5. The adjustable stops 52 can be round holes, elliptical holes, oblong holes, slots, or other hole / slot structures that can cooperate with the locking mechanism 6 for positioning. When the adjustable stops 52 at different positions cooperate with the locking mechanism 6, the hanging strap 5 can form closed suspension rings of different circumferences. Specifically, when the crossbar diameter is large or the crossbar shape is wide, the adjustable stop 52 closer to the free end of the hanging strap 5 can be selected to cooperate with the locking mechanism 6, resulting in a larger enclosing size of the closed suspension ring, ensuring that the hanging strap 5 can smoothly pass over the crossbar and complete locking. When the crossbar diameter is small or a more compact suspension of the drainage bag is required, the adjustable stop 52 relatively closer to the fixed end of the hanging strap 5 can be selected to cooperate with the locking mechanism 6, resulting in a smaller enclosing size of the closed suspension ring, thus improving the fit between the hanging strap 5 and the outer surface of the crossbar.

[0025] The aforementioned adjustment method does not merely achieve suspension by extending the hanging strap 5, but rather through the selective locking of multiple adjustment ports 52 and the locking mechanism 6, allowing the hanging strap 5 to form closed suspension states with different enclosure sizes according to different crossbar specifications. This structure balances adaptability and anti-detachment: for thicker crossbars, the hanging strap 5 can smoothly encircle the crossbar with a larger enclosure size; for thinner crossbars, the hanging strap 5 can fit snugly against the crossbar with a smaller enclosure size, reducing the gap between the hanging strap 5 and the crossbar, thereby reducing the risk of the bag 1 swaying, tilting, or jumping off.

[0026] In this embodiment, the reinforcing plate 4 has a slot for the hanging strap 5 to pass through or be pulled out. One end of the hanging strap 5 can be fixedly connected to the reinforcing plate 4, and the other end is a free end that can be pulled out through the slot on the reinforcing plate 4. In actual use, the caregiver can hold the free end of the hanging strap 5, pass the hanging strap 5 around the bed rail crossbar or the support crossbar, and then pull the position with the selected adjustment stop 52 to the locking mechanism 6 for locking. The slot provides guidance for the hanging strap 5, so that the hanging strap 5 maintains a relatively stable movement path during the pulling out, retraction and adjustment process; on the other hand, the slot, in cooperation with the reinforcing plate 4, can disperse the pulling force of the hanging strap 5 on the reinforcing plate 4, and avoid the pulling force being concentrated on the flexible film of the bag body 1.

[0027] like Figure 3 and Figure 4 As shown, the hanging strap 5 has multiple anti-slip ribs 51 on the side facing the crossbar. These anti-slip ribs 51 are spaced apart along the length of the hanging strap 5 and can be raised in the form of strips, blocks, teeth, or arcs. The anti-slip ribs 51 are located on the inner side of the hanging strap 5, that is, the side facing the crossbar when the hanging strap 5 is wrapped around the crossbar to form a closed suspension loop. After the hanging strap 5 is tightened, the anti-slip ribs 51 contact or abut against the outer surface of the crossbar, increasing the frictional resistance between the hanging strap 5 and the crossbar.

[0028] Furthermore, the anti-slip rib 51 is provided with a suction cup opening 511. The suction cup opening 511 can be a concave cavity structure formed on the surface of the anti-slip rib 51, with its opening facing the surface of the crossbar. When the hanging strap 5 surrounds the crossbar and is locked by the locking mechanism 6, the hanging strap 5 is tightened under the gravity of the bag body 1, the anti-slip rib 51 is pressed against the outer surface of the crossbar, and the edge of the suction cup opening 511 is in contact with the surface of the crossbar. When the surface of the crossbar is relatively smooth, the suction cup opening 511 can form a certain adsorption fit with the surface of the crossbar; even if a completely sealed vacuum adsorption cannot be formed, the concave edge of the suction cup opening 511 can improve the local fitting and contact resistance between the hanging strap 5 and the crossbar, thereby further improving the anti-slip effect.

[0029] like Figure 2 As shown, the locking mechanism 6 is mounted on the reinforcing plate 4 and is used to limit and lock the adjustment stop 52 on the strap 5. The locking mechanism 6 includes a clamp 61 mounted on the reinforcing plate 4, a locking ball 62 that cooperates with the clamp 61, and a telescopic rod 63 for moving the locking ball 62. It should be noted that in this embodiment, the locking ball 62 is preferably spherical or has a spherical outer contour, but it can also be hemispherical, cylindrical, or other locking protrusions with an arc-shaped guide effect. Because the locking ball 62 has an arc or smooth outer contour, it is less likely to scratch the strap 5 when it enters the clamp 61, and at the same time, it can form a smoother pressing and retraction action.

[0030] The reinforcing plate 4 is equipped with a clamp 61, which can be integrally formed with the reinforcing plate 4 or fixed to the reinforcing plate 4 by bonding, welding, snap-fitting, or screwing. The side of the clamp 61 facing the locking ball 62 has a groove for accommodating the locking ball 62. The width of the groove opening can be slightly smaller than the maximum outer diameter of the locking ball 62, so that the locking ball 62 produces a certain interference fit effect when entering the groove. The clamp 61 can have a certain elastic deformation capability; when the locking ball 62 is pressed into the groove, the groove opening of the clamp 61 slightly opens; after the locking ball 62 enters the groove, the clamp 61 relies on its own elastic restoring force to hold the locking ball 62, thereby forming a reliable lock.

[0031] The reinforcing plate 4 is also equipped with a telescopic rod 63, one end of which is connected to the locking ball 62, and the other end can be inserted into or slidably connected to the mounting hole, guide hole, or guide seat of the reinforcing plate 4. The telescopic rod 63 can move towards or away from the clamp 61, thereby causing the locking ball 62 to move towards or away from the clamp 61. When it is necessary to lock the strap 5, the caregiver places the selected adjustment stop 52 of the strap 5 between the clamp 61 and the locking ball 62, and then pushes the telescopic rod 63, causing the telescopic rod 63 to move the locking ball 62 toward the clamp 61. The locking ball 62 passes through or abuts into the adjustment stop 52 and further embeds into the slot of the clamp 61. At this time, the adjustment stop 52 of the strap 5 is limited between the locking ball 62 and the clamp 61, and the strap 5 cannot freely retract along its length, thus forming a locked state.

[0032] When it is necessary to remove the drainage bag or readjust the size of the hanging strap 5, the nursing staff can pull the telescopic rod 63 away from the clamp 61. This causes the telescopic rod 63 to disengage the locking ball 62 from the groove of the clamp 61. The locking ball 62 no longer limits the adjustment position 52, and the free end of the hanging strap 5 can then be released from the locking mechanism 6 or locked at another adjustment position 52. The telescopic rod 63 can also be equipped with a limiting protrusion, a limiting ring, or a limiting step to prevent it from completely detaching from the reinforcing plate 4. In this way, the locking mechanism 6 can maintain its structural integrity while fulfilling the function of releasable adjustment, preventing the loss of small parts during clinical use.

[0033] The usage process of this embodiment is as follows: When using the device, the nurse first connects the needle 21 or the distal connector of the drainage tube 2 to the patient's drainage site or corresponding tubing, and controls the opening and closing of the drainage channel as needed using the stop clamp 3. Then, the bag 1 is placed at a suitable height, ensuring it is lower than the drainage site to guarantee smooth drainage. The nurse holds the free end of the strap 5, wraps the strap 5 around the outer perimeter of the bed rail or support crossbar, and selects an appropriate adjustment stop 52 based on the crossbar diameter. If the crossbar is thicker, an adjustment stop 52 that forms a larger closed loop with the strap 5 is selected; if the crossbar is thinner, an adjustment stop 52 that forms a smaller closed loop with the strap 5 is selected. After selection, the corresponding adjustment stop 52 is placed between the clamp 61 and the locking ball 62, and the telescopic rod 63 is pushed, causing the locking ball 62 to engage with the clamp 61 and press the adjustment stop 52, thus completing the suspension locking.

[0034] After locking, the weight of the bag body 1 and the liquid inside the bag first acts on the upper connecting area of ​​the bag body 1, and then is transferred to the reinforcing plate 4. Due to its high rigidity, the reinforcing plate 4 can convert the local tension at the upper end of the bag body 1 into a load-bearing force distributed along the length of the reinforcing plate 4. This load-bearing force is further transferred to the hanging strap 5, causing the hanging strap 5 to be in a taut state. When the hanging strap 5 is wrapped around the outer periphery of the crossbar, its two side sections bear tension respectively, and the direction of the tension extends roughly along the length of the hanging strap 5 itself. Since the hanging strap 5 forms a closed suspension ring around the crossbar, the downward weight of the bag body 1 will cause the hanging strap 5 to exert a covering pressure on the crossbar, causing the anti-slip ribs 51 on the inner side of the hanging strap 5 to press against the surface of the crossbar.

[0035] From a force perspective, the more liquid inside the bag 1, the greater the downward pull of the bag 1 on the reinforcing plate 4, and the greater the tension of the strap 5. When the strap 5 is tensioned, it exerts a greater normal compressive force on the crossbar, increasing the contact pressure between the anti-slip rib 51 and the crossbar, and consequently increasing the frictional resistance. This frictional resistance is in the opposite direction to the tendency of the bag 1 to slide laterally along the crossbar, thus inhibiting the bag 1 from sliding along the length of the crossbar. Especially when the patient is turned over, the bed rails are raised or lowered, or caregivers push the bed, the bag 1 may be subjected to lateral disturbance forces, which can cause the strap 5 to tend to move along the crossbar. At this time, the anti-slip rib 51 and the suction cup opening 511 together increase the resistance between the strap 5 and the crossbar, making it less likely for the bag 1 to experience significant lateral displacement.

[0036] Simultaneously, when the strap 5 is pulled and adheres to the crossbar, the suction cup opening 511 is pressed tightly and comes into contact with the surface of the crossbar. When the bag body 1 tends to swing, the inner side of the strap 5 may show a tendency to peel off from the surface of the crossbar. The suction effect of the suction cup opening 511 and its edge blocking effect will form a reverse resistance to this peeling trend. In other words, the suction cup opening 511 can not only increase local friction, but also delay the separation of the strap 5 from the surface of the crossbar when the strap 5 is subjected to an upward or outward lifting action for a short time, thereby reducing the possibility of the strap 5 loosening instantly.

[0037] Further analysis of the force at the locking point. When the bag body 1 is in a suspended state, the free end of the hanging strap 5 is subjected to a pull-back force along the length of the hanging strap 5. This pull-back force comes from the tension of the hanging strap 5 generated by the weight of the bag body 1. If the locking mechanism 6 cannot reliably limit the movement, the free end of the hanging strap 5 will gradually slide out of the locking mechanism 6 under the action of this pull-back force, causing the closed suspension ring to enlarge or even fail. In this embodiment, the locking ball 62 passes through or abuts into the adjusting stop 52 and forms a locking engagement with the groove of the clamp 61. The pull-back force of the hanging strap 5 acts on the hole wall or groove wall of the adjusting stop 52, and the hole wall of the adjusting stop 52 transmits this force to the locking ball 62. The locking ball 62 then transmits the force to the clamp 61 and the telescopic rod 63. The clamp 61 supports and blocks the locking ball 62 through its groove, while the telescopic rod 63 maintains the position of the locking ball 62. Together, they prevent the locking ball 62 from disengaging from the adjusting stop 52. Therefore, the free end of the strap 5 is difficult to retract under the gravity of the bag body 1.

[0038] When subjected to an upward impact, such as when a patient turns over causing traction on the tubing, when the bed rails rise or fall causing a momentary change in force on the drainage bag, or when the bag 1 is accidentally touched during nursing procedures, the bag 1 may experience a momentary upward displacement. For ordinary open hooks, when the bag 1 displaces upward, the hook is likely to detach from the crossbar along its opening direction. However, in this embodiment, the hanging strap 5 forms a closed suspension ring around the crossbar, with the crossbar located inside the closed ring. Even if the bag 1 experiences a short-term upward jump, the crossbar remains enclosed by the hanging strap 5, lacking an open exit channel. At this time, the upward force may cause the hanging strap 5 to loosen locally or change its tension distribution, but the adjusting stop 52 is still limited by the locking mechanism 6, and the hanging strap 5 will not open directly. Therefore, it can effectively prevent the bag 1 from falling off the crossbar.

[0039] When the bag 1 is swayed laterally, it will swing left and right around the crossbar. During the swing, the force on the two sides of the strap 5 will change alternately: the tension of the strap on the side closer to the swing direction increases, while the tension of the strap on the other side decreases relatively. Since the strap 5 is a flexible structure, it can adapt to the shape of the outer periphery of the crossbar and maintain a covering state; the reinforcing plate 4 limits excessive deformation of the upper end of the bag 1, so that the force on both sides of the strap 5 can be transmitted to the bag 1 more evenly. The anti-slip rib 51 is subjected to greater clamping force on the tension side of the strap 5, generating greater anti-slip friction with the crossbar; on the side with less tension, the suction cup opening 511 and the closed-loop structure can still maintain a certain adhesion and limiting effect. Therefore, even if the bag 1 swings, the strap 5 is not easy to slip or come off along the crossbar.

[0040] When the liquid sloshes inside the bag 1, the inertia of the liquid causes the bag 1 to be subjected to periodically changing tensile and lateral forces. Under such repeated loads, ordinary open hooks are prone to buckling at the hook point, which in turn increases the gap between the hook and the crossbar. In this embodiment, the encirclement size of the strap 5 can be pre-selected by adjusting the stop 52, so that the strap 5 maintains a suitable gap or fit with the crossbar after locking. For thinner crossbars, when using a smaller encirclement size, the anti-slip ribs 51 on the inner side of the strap 5 can more fully abut against the crossbar, so that a stable contact is formed between the strap 5 and the crossbar; for thicker crossbars, when using a larger encirclement size, the strap 5 can still completely wrap around the crossbar and lock into a closed loop, without the problem of insufficient hooking depth due to the thickness of the crossbar.

[0041] In this embodiment, the reinforcing plate 4 also serves to prevent the bag 1 from tilting. When the bag 1 is suspended only by a single-point hook, the bag 1 is prone to rotating around the hook point, causing the bag 1 to tilt. After the bag 1 tilts, the liquid distribution inside the bag is uneven, which may affect the volume observation and drainage stability. In this embodiment, the hanging strap 5 cooperates with the reinforcing plate 4 to form a relatively stable connection area between the force-bearing point of the hanging strap 5 and the reinforcing plate 4. The reinforcing plate 4 extends laterally along the upper end of the bag 1, which can distribute the suspension force to a wider area at the upper end of the bag 1. In this way, the bag 1 is less likely to deflect significantly when subjected to force, which is beneficial to keeping the bag 1 suspended vertically.

[0042] The connection between the chuck 61, locking ball 62, and telescopic rod 63 also helps improve locking reliability. The locking ball 62 is positioned at the end of the telescopic rod 63 facing the chuck 61, and the telescopic rod 63 provides a path for the locking ball 62 to move closer to or away from the chuck 61. After the locking ball 62 enters the slot of the chuck 61, the chuck 61 forms radial clamping and axial obstruction of the locking ball 62, while the wall of the adjusting stop 52 is confined between the chuck 61 and the locking ball 62. When the strap 5 is under tension, the adjusting stop 52 tends to disengage the locking ball 62 from the chuck 61. However, since the locking ball 62 is already embedded in the slot, and the slot opening obstructs the locking ball 62, it is difficult for the locking ball 62 to directly exit along the direction of the strap 5's tension. Therefore, the tension of the strap 5 will not directly cause the locking mechanism 6 to release, but will be shared by the chuck 61, telescopic rod 63, and reinforcing plate 4.

[0043] For ease of use, the telescopic rod 63 can be configured as an exposed operating part, allowing caregivers to lock or unlock by pressing, pushing, or flicking the telescopic rod 63. The telescopic rod 63 can also cooperate with an elastic element, causing the locking ball 62 to naturally approach the clamp 61; when unlocking is required, the caregiver pulls the telescopic rod 63, causing the locking ball 62 to disengage from the clamp 61 slot, and upon release, the locking ball 62 returns to its original position under the action of the elastic element. The above structure can be selected based on manufacturing costs and usage requirements, without affecting the core function of this utility model: achieving an adjustable closed-loop anti-slip suspension through the strap 5, the adjusting stop 52, and the locking mechanism 6.

[0044] To further enhance safety, the edges of the adjusting port 52 can be rounded or thickened to reduce the risk of the locking ball 62 cutting the hanging strap 5 during repeated locking. The thickness of the hanging strap 5 can be designed according to the maximum liquid capacity of the bag body 1, ensuring sufficient tensile strength even when the bag is full. The anti-slip rib 51 can be integrally formed with the hanging strap 5, or it can be fixed to the inside of the hanging strap 5 through secondary injection molding, bonding, or hot pressing. The suction cup opening 511 can be integrally formed with the anti-slip rib 51 to simplify the manufacturing process.

[0045] In clinical use, this embodiment can be quickly adjusted according to the diameter of different bed rail crossbars or support crossbars. For example, when the drainage bag needs to be suspended on a thinner, round bed rail crossbar, the nurse selects the adjustment stop 52 near the fixed end of the hanging strap 5, so that the hanging strap 5 forms a smaller closed loop. The anti-slip rib 51 and the suction cup opening 511 are pressed tightly against the surface of the crossbar, and the bag body 1 is not easy to slide along the direction of the crossbar. When the drainage bag needs to be suspended on a thicker infusion stand crossbar or an irregularly shaped crossbar, the nurse selects the adjustment stop 52 near the free end of the hanging strap 5, so that the hanging strap 5 forms a larger closed loop, ensuring that the hanging strap 5 can smoothly surround the crossbar and complete the locking. Regardless of which adjustment stop 52 is selected, the locking mechanism 6 can limit the selected adjustment stop 52, so that the closed suspension ring remains stable.

[0046] Compared with traditional open hooks, the anti-detachment effect of this embodiment is mainly reflected in the following aspects: First, the hanging strap 5 forms a closed suspension ring, with the crossbar located inside the closed ring, eliminating the exit path of the open hook; Second, multiple adjustment ports 52 realize the adjustment of the enclosure size, so that the hanging strap 5 can adapt to different crossbars, reducing the problem of excessive gaps caused by the crossbar being too thin; Third, the anti-slip ribs 51 and the suction cup port 511 improve the contact resistance and adhesion stability between the hanging strap 5 and the crossbar, reducing lateral slippage and shaking; Fourth, the locking ball 62 and the clamp 61 cooperate to form a mechanical limit on the adjustment port 52, making it difficult for the hanging strap 5 to be released when it is pulled, shaken, or jumps up for a short time; Fifth, the reinforcing plate 4 disperses the force on the upper end of the bag body 1, reducing the risk of local tearing or tilting of the flexible bag body 1.

[0047] It should be noted that the crossbar referred to in this embodiment can be a bed rail crossbar, an IV stand crossbar, a nursing support crossbar, or other rod-shaped support that can suspend drainage bags. The cross-section of the crossbar can be circular, elliptical, rectangular, or other irregular shapes. Because the hanging strap 5 is flexible, it can adapt to the outer contour of crossbars with different cross-sections; and because multiple adjustment ports 52 can change the enclosure size of the closed suspension ring, this embodiment is not limited to a crossbar of a certain diameter or shape.

[0048] In this embodiment, the hanging strap 5, reinforcing plate 4, and locking mechanism 6 can be integrated as an anti-detachment suspension assembly on the upper end of the bag body 1. During manufacturing, the reinforcing plate 4 can be formed first, then the hanging strap 5 and locking mechanism 6 can be assembled onto the reinforcing plate 4, and finally the reinforcing plate 4 can be fixed to the upper end of the bag body 1; alternatively, the reinforcing plate 4 can be heat-pressed to the upper end of the bag body 1 before assembling the hanging strap 5 and locking mechanism 6. The clamp 61 can be integrally injection molded with the reinforcing plate 4, the telescopic rod 63 can be slidably installed near the reinforcing plate 4 or the clamp 61, and the locking ball 62 can be fixed to the end of the telescopic rod 63. This assembly method has a simple structure, few parts, facilitates mass production, and also helps control the cost of clinical disposable supplies.

[0049] In summary, this embodiment provides a reinforcing plate 4 at the upper end of the bag body 1, a hanging strap 5 that can wrap around a crossbar at the reinforcing plate 4, and multiple adjustable stops 52 on the hanging strap 5. This allows the hanging strap 5 to form closed suspension rings of different enclosure sizes according to the specifications of the crossbar. Simultaneously, the cooperation between the clamp 61, the locking ball 62, and the telescopic rod 63 reliably limits the selected adjustable stop 52, preventing the hanging strap 5 from easily retracting under stress. The anti-slip ribs 51 and the suction cup opening 511 further enhance the friction, adhesion, and anti-peeling ability between the hanging strap 5 and the crossbar. The above structures work together to ensure that the drainage bag, when used in gastroenterology clinics, balances hanging adaptability, adjustment convenience, anti-slip properties, anti-shaking, and anti-drop properties, thereby improving the stability and safety of the drainage bag.

[0050] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
