Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a drainage bag traction device. Background Technology

[0002] In clinical practice, some patients require abdominal or thoracic drainage tubes after surgery, and these patients often need to carry drainage bags to drain accumulated fluid.

[0003] Conventional drainage bags only have short straps and no hooks. In actual clinical settings, most hospital beds are not equipped with hooks. Even if some beds have hooks to act as traction devices for the drainage bags, their positions are often fixed and cannot be moved. When a patient is bedridden with the drainage tube in place and the bed is not equipped with hooks, the drainage bag can only be placed on the ground. This not only increases the risk of infection for the patient but may also cause the drainage tube to slip off. If the bed is equipped with fixed hooks, due to the limited length of the drainage tube and the fixed position of the drainage bag, the patient is very likely to pull on the drainage tube when moving in bed, which may also cause the drainage tube to slip off and reduce the patient's comfort.

[0004] Although the drainage bag comes with a strap that can be hung on a hospital bed with hooks, the strap is short. When patients get out of bed, they can only carry the drainage bag by hand, which may cause backflow of drainage fluid and lead to infection. Therefore, a drainage bag traction device is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Example 1

[0027] Please see Figure 1 - Figure 5This utility model provides a drainage bag hanging device, including a weight sensor 1, an indicator light 2 provided on the side wall of the weight sensor 1; a hook 7 installed at the bottom end of the weight sensor 1; a cylindrical tube 3 fixedly connected to the top end of the weight sensor 1; a fixing block 51 fixedly connected to the top end of the cylindrical tube 3; a rectangular plate 5 in contact with the middle of the fixing block 51; a fixing shell 61 fixedly connected to the middle of the top end of the rectangular plate 5; a sliding shell 62 slidably connected to the inner wall of the fixing shell 61; and the end of the sliding shell 62... A clamping plate 6 is fixedly connected; a rotating rod 33 is rotatably connected through the side wall of the cylindrical tube 3; a circular plate 31 is fixedly connected to the end of the rotating rod 33; multiple sets of connecting straps 35 are fixedly connected to the outer wall of the rotating rod 33; the connecting straps 35 slide in the middle of the rectangular plate 5; the connecting straps 35 slide through the top of the cylindrical tube 3; a connecting block 32 is fixedly connected to the end of the connecting straps 35; the bottom end of the connecting block 32 contacts the top end of the rectangular plate 5; during operation, the drainage bag has a relatively short hanging strap, which makes it easier for the patient to get out of bed. The patient currently has to carry the drainage bag by hand, which could easily cause backflow of the drainage fluid and lead to infection. To address this, a drainage bag hanging device is proposed. When in use, the drainage bag can be hung on the hook 7. The weight sensor 1 will constantly detect the weight of the drainage bag. If it is overweight, the internal electronic components will send a signal through the indicator light 2, indicating that the drainage bag needs to be replaced. When the patient is lying in bed, the drainage bag can be hung on the bed rail through the cooperation of the fixed shell 61, the sliding shell 62 and the clamp 6. When the patient needs to get out of bed, the limit of the circular plate 31 can be released, and then the connecting block 32 can be pulled. The connecting block 32 will pull out the connecting strap 35 wound on the outer wall of the rotating rod 33. During the pulling process, the rotating rod 33 and the circular plate 31 will rotate to ensure smooth pulling. After pulling out a certain length, the patient can hang the connecting strap 35 on their shoulder. This eliminates the need for the patient to carry the drainage bag by hand, reducing the risk of backflow of drainage fluid and infection.

[0028] Example 2

[0029] Furthermore, such as Figure 1 - Figure 2 and Figure 5As shown, a hinge block 72 is fixedly connected to the side wall of the hook 7; a baffle 71 is hinged to the middle of the hinge block 72; the end of the baffle 71 slides on the inner wall of the end of the hook 7; a limiting groove 74 is formed on the inner wall of the end of the hook 7; a rubber block 73 is fixedly connected to the side wall of the end of the baffle 71; the rubber block 73 contacts the inner wall of the limiting groove 74. During operation, when the drainage bag is hung on the hook 7, the baffle 71 can be pushed, and the baffle 71 will rotate with the hinge block 72. At the same time, the rubber block 73 will rotate due to its elasticity and curved surface. The drainage bag can be hung on the hook 7 after it is disengaged from the inner wall of the limiting groove 74. After the drainage bag is installed, the baffle 71 can be pushed in the opposite direction to push the end of the baffle 71 into the inner wall of the end of the hook 7. During the pushing process, the rubber block 73 will be squeezed and deformed until the rubber block 73 overlaps with the limiting groove 74. At this time, the rubber block 73 will reset through its own elasticity and be stuck in the inner wall of the limiting groove 74. This can block the drainage bag, reduce the risk of the drainage bag falling off the hook 7, and improve its practicality.

[0030] Example 3

[0031] Furthermore, such as Figure 1 - Figure 2 and Figure 4 As shown, a rectangular shell 41 is fixedly connected to the side wall of the cylindrical tube 3 near the front side of the cylindrical tube 3; a limiting plate 44 is elastically connected to the inner wall of the rectangular shell 41 through a spring 43; the limiting plate 44 is slidably connected to the inner wall of the rectangular shell 41; one end of the spring 43 is fixedly connected to the end of the limiting plate 44; the other end of the spring 43 is fixedly connected to the inner wall of the rectangular shell 41; the outer wall of the circular plate 31 has rectangular grooves 36 in multiple sets; the end of the limiting plate 44 contacts the inner wall of the rectangular groove 36. During operation, when the connecting belt 35 needs to be pulled, the connecting strip 4 must be pulled first. The rectangular block 42 and the limiting plate 44 move synchronously. When the limiting plate 44 moves, it will squeeze the spring 43. The limiting plate 44 completely disengages from the inner wall of the rectangular groove 36. At this time, the connecting belt 35 can be pulled. After the length of the connecting belt 35 is adjusted, the connecting strip 4 is released. At this time, the spring 43 will push the limiting plate 44 to move in the opposite direction through its own elasticity and insert into the inner wall of the rectangular groove 36 to ensure the stability of the connecting belt 35. By setting multiple sets of rectangular grooves 36, it can be ensured that the connecting belt 35 can be stably used by being limited by the limiting plate 44 at different lengths.

[0032] Furthermore, such as Figure 2 and Figure 4As shown, a rectangular block 42 is fixedly connected to the top of the limiting plate 44; the rectangular block 42 is slidably connected to the top of the rectangular shell 41; a connecting strip 4 is fixedly connected to the top of the rectangular shell 41; multiple sets of rectangular shell 41, rectangular block 42, spring 43, and limiting plate 44 are provided; and multiple sets of rectangular shell 41, rectangular block 42, spring 43, and limiting plate 44 are symmetrically arranged with the center line of the connecting strip 4 as the axis of symmetry. During operation, the connecting strip 4 can control multiple sets of rectangular blocks 42 to move together with the limiting plate 44, ensuring that they can synchronously release the limiting of multiple sets of circular plates 31, thus improving convenience. In addition, the rectangular block 42 slides horizontally through the upper surface of the limiting plate 44, ensuring that when the connecting strip 4 is pulled, the limiting plate 44 can be stably moved horizontally by the rectangular block 42.

[0033] Example 4

[0034] Furthermore, such as Figure 2 and Figure 4 As shown, a spiral spring 34 is sleeved on the outer wall of the rotating rod 33; one end of the spiral spring 34 is fixedly connected to the outer wall of the rotating rod 33; the other end of the spiral spring 34 is fixedly connected to the inner wall of the cylindrical tube 3. During operation, when the connecting belt 35 is pulled, the rotating rod 33 will rotate. When the rotating rod 33 rotates, it will cause the spiral spring 34 to twist and deform. When the connecting belt 35 needs to be retracted, the connecting belt 35 is released, and the limiting position of the circular plate 31 is released. At this time, the spiral spring 34 will drive the rotating rod 33 to rotate in the opposite direction through its own elasticity, that is, to rewind the connecting belt 35. There is no need for manual rewinding, which improves convenience.

[0035] Furthermore, such as Figure 3 As shown, a second medical magnetic block 53 is fixedly attached to the bottom of the rectangular plate 5; a first medical magnetic block 52 is fixedly attached to the middle of the fixing block 51; the bottom of the second medical magnetic block 53 contacts the top of the first medical magnetic block 52. During operation, the first medical magnetic block 52 and the second medical magnetic block 53 have the characteristic of attracting each other despite being of opposite phases. When in use, if the bed rail is too high, the length of the connecting strap 35 can be adjusted appropriately, and then the rectangular plate 5 can be pulled to separate it from the fixing block 51. This allows the drainage bag to be hung on the bed rail and its height can be adjusted, improving its practicality.

[0036] Furthermore, such as Figure 3As shown, a second spring 63 is fixedly connected to the inner wall of the sliding shell 62; the other end of the second spring 63 is fixedly connected to the inner wall of the fixed shell 61; a friction pad 64 is fixedly connected to the side wall of the clamping plate 6; the end of the clamping plate 6 is set as an inclined surface. During operation, the friction pad 64 can ensure the stability of the clamping plate 6 on the bed rail. When the clamping plate 6 is in use, it is directly hung on the bed rail. When it comes into contact with the bed rail, the bed rail will push it to move along its inclined surface. The clamping plate 6 will drive the sliding shell 62 to move. The sliding shell 62 will stretch the second spring 63 until the clamping plate 6 is stuck on the outside of the bed rail. At this time, the second spring 63 will always pull the sliding shell 62 through its own elasticity, so that the clamping plate 6 can be stably clamped on the bed rail, ensuring the stability of the drainage bag.

[0037] Working principle: When in use, the drainage bag can be hung on hook 7. At this time, the weight sensor 1 will constantly detect the weight of the drainage bag. If it is overweight, the internal electronic components will send a signal through the indicator light 2, indicating that the drainage bag can be replaced. When the patient is lying in bed, it can be hung on the bed rail by the cooperation of the fixed shell 61, the sliding shell 62 and the clamp 6. When the patient needs to get out of bed, the limit of the circular plate 31 can be released, and then the connecting block 32 can be pulled. The connecting block 32 will pull out the connecting strap 35 wound on the outer wall of the rotating rod 33. During the pulling process, the rotating rod 33 and the circular plate 31 will rotate, which will cause the spiral spring 34 to twist and deform, ensuring the smoothness of the pull-out. After being pulled out to a certain length, the patient can hang the connecting strap 35 on his shoulder, so that the patient does not need to carry the drainage bag by hand, reducing the backflow of drainage fluid and thus reducing the risk of infection. When the connecting strap 35 needs to be retracted, the connecting strap 35 is loosened and the limiting position of the circular plate 31 is released. At this time, the spiral spring 34 will drive the rotating rod 33 to rotate in the opposite direction through its own elasticity, that is, to rewind the connecting strap 35. There is no need for manual rewinding, which improves convenience.

[0038] When the drainage bag is hung on the hook 7, the baffle 71 can be pushed, and the baffle 71 will rotate with the hinge block 72. At the same time, the rubber block 73 will detach from the inner wall of the limiting groove 74 due to its own elasticity and arc surface. In this way, the drainage bag can be hung on the hook 7. After the drainage bag is installed, the baffle 71 can be pushed in the opposite direction, pushing the end of the baffle 71 into the inner wall of the end of the hook 7. During the pushing process, the rubber block 73 will be squeezed and deformed until the rubber block 73 overlaps with the limiting groove 74. At this time, the rubber block 73 will reset due to its own elasticity and be stuck in the inner wall of the limiting groove 74. This can block the drainage bag, reduce the risk of the drainage bag falling off the hook 7, and improve practicality.

[0039] When in use, the clamp 6 is hung directly on the bed rail. When it comes into contact with the bed rail, the bed rail will push it to move along its slope. The clamp 6 will drive the sliding shell 62 to move. The sliding shell 62 will stretch the second spring 63 until the clamp 6 is stuck on the outside of the bed rail. At this time, the second spring 63 will continue to pull the sliding shell 62 through its own elasticity, so that the clamp 6 can be stably clamped on the bed rail, ensuring the stability of the drainage bag.

[0040] In addition, if the bed rails are too high during use, the length of the connecting strap 35 can be adjusted appropriately, and then the rectangular plate 5 can be pulled to separate it from the fixing block 51. This allows the drainage bag to be hung on the bed rails while its height can be adjusted, improving its practicality.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
