Description

Technical Field

[0001] This invention relates to the field of drainage tube care technology, and in particular to a painless drainage tube fixation device. Background Technology

[0002] In the medical field, drainage tubes are commonly used for postoperative wound or body cavity fluid drainage. They need to be stably fixed to the patient's skin for a long period of time to ensure continuous and smooth drainage and avoid complications such as fluid reflux and wound infection caused by tube displacement or dislodgement. Currently, the most common methods for fixing drainage tubes in clinical practice are using medical tape or magnetic adsorption devices. Medical tape adheres the drainage tube to the skin through adhesive bonding.

[0003] However, these methods fail to consider that human sweat secretion and limb movement can easily weaken the adhesive of the tape, causing the drainage tube to loosen. Magnetic devices rely on magnetic force to hold the drainage tube in place; however, even slight external impacts or changes in body position can disrupt the magnetic balance, causing the drainage tube to shift. All of these fixation methods suffer from insufficient stability, making the drainage tube prone to detachment. This not only affects the drainage effect but may also increase the risk of secondary trauma to the patient, failing to meet the clinical need for long-term, stable fixation of the drainage tube.

[0004] Therefore, a painless drainage tube fixation device is proposed to address the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, the present invention provides a painless drainage tube fixing device, which aims to improve the problem of easy dislodgement of drainage tubes in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A painless drainage tube fixing device includes a drainage tube, an airbag 1 slidably connected to the outer right side of the drainage tube, an air inlet valve provided at the top of the airbag 1, multiple air supply tubes fixedly connected to the left side of the airbag 1, an airbag 2 fixedly connected to the left side of the multiple air supply tubes, two extension sleeves slidably connected to the outside of the drainage tube, multiple receiving holes opened inside the two extension sleeves, multiple cavities 1 opened inside the two extension sleeves, and an adjustment component for controlling the distance between the two extension sleeves slidably connected inside the cavity 1;

[0008] As a further description of the above technical solution:

[0009] The adjustment assembly includes multiple teeth and an extension plate. The exterior of the multiple teeth is fixedly connected to the inner wall of the cavity. Two cavities are opened on the left and right sides of the extension plate. Two springs are installed inside the cavity. A sliding plate is slidably connected inside the cavity. The top of the sliding plate is fixedly connected to the teeth.

[0010] As a further description of the above technical solution:

[0011] The outer left and right sides of the guide tube are fixedly connected with sheaths, and the outer side of the guide tube is provided with a protective layer, which is composed of nano-silver antibacterial coating material.

[0012] As a further description of the above technical solution:

[0013] The middle part of the second airbag is slidably connected to the outside of the guide tube, and the outside of the air delivery tube is slidably connected to the inside of the receiving hole.

[0014] As a further description of the above technical solution:

[0015] The exterior of the second airbag is in contact with the exterior of one of the extended sleeves, and the exterior of the first airbag is in contact with the exterior of the other extended sleeve.

[0016] As a further description of the above technical solution:

[0017] One end of the spring is fixedly connected to the inner wall of the cavity two, and the other end of the spring is fixedly connected to the outside of the sliding plate;

[0018] As a further description of the above technical solution:

[0019] The outer surface of the second tooth is in contact with the inner wall of the cavity, and the second tooth engages with the outer surface of the first tooth.

[0020] As a further description of the above technical solution:

[0021] The guide tube is made of silicone, and the sheath is made of polyurethane.

[0022] The present invention has the following beneficial effects:

[0023] 1. In this invention, traditional drainage tubes are usually fixed with tape or magnetic attraction, which makes them prone to falling off. By injecting gas into the air inlet valve, the gas passes through airbag one and multiple air delivery tubes into airbag two, causing airbag two to inflate inside the patient's body and airbag one to inflate outside the patient's body. This allows the drainage tube to be stably fixed to the patient's body, preventing it from falling off.

[0024] 2. In this invention, because patients have different body shapes, their skin thickness will also be different. Therefore, when the drainage tube is fixed to the outside of the patient's skin, it is necessary to adjust the distance between the two extension sleeves according to the patient's skin thickness. Then, pulling the extension sleeve will cause the second tooth to enter the inside of the second cavity and disengage from the first tooth, so that the two extension sleeves can move away from each other. When the appropriate distance is reached, the second tooth will re-engage with the first tooth under the action of the spring return force, thus fixing the distance between the two extension sleeves and enabling the device to be adjusted according to the patient's skin thickness.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 This invention provides an embodiment of a painless drainage tube fixation device, comprising a drainage tube 1 made of silicone. The flexible properties of silicone wrap around the clinically used drainage tube, providing support and protection. Silicone's elasticity also allows it to adapt to slight movements of the drainage tube, reducing damage from hard friction. An airbag 2 is slidably connected to the right side of the drainage tube 1. The airbag 2 is positioned on the right side of the drainage tube 1 and expands after being inflated by gas injected through the top air inlet valve 3. Its exterior contacts and applies pressure to the right-side extension sleeve 6, serving as an external fixation point. This, in conjunction with the second airbag 5, forms a bidirectional fixing force, ensuring the device stably conforms to the patient's skin. An air inlet valve 3 is located at the top of the airbag 2. This valve connects to a medical inflation device, controlling the gas injection into the airbag 2. It is a key interface for achieving airbag inflation and fixation, ensuring the sealing and controllability of gas injection.

[0037] Multiple air supply pipes 4 are fixedly connected to the left side of airbag 1 2. These pipes connect airbag 1 2 to airbag 2 5, transmitting gas from airbag 1 2 to airbag 2 5, causing both to inflate synchronously and ensuring a uniform distribution of the fixing force. Simultaneously, their external parts are slidably connected to the receiving holes 7 of the extension sleeve 6, adapting to the adjustment of the spacing of the extension sleeve 6 and preventing pipe twisting. Airbag 2 5 is fixedly connected to the left side of the multiple air supply pipes 4. Airbag 2 5 is located on the left side outside the guide tube 1. After receiving gas transmitted from the air supply pipes 4, it inflates, and its external part contacts and applies pressure to the left side of the extension sleeve 6, serving as an internal fixation mechanism. The fixed fulcrum, together with the first airbag 2, clamps and fixes the drainage tube 1 and the internal drainage tube to the patient's skin surface through bidirectional thrust. The middle part of the second airbag 5 is slidably connected to the outside of the drainage tube 1. Two extension sleeves 6 are slidably connected to the outside of the drainage tube 1, one on each side. As a transmission component of the airbag fixing force, its outside contacts the inflated first airbag 2 and the second airbag 5, receives the pressure applied by the airbag and tightens in the middle to realize the compression and fixation of the drainage tube 1. At the same time, the inside contains the adjustment component to support the spacing adjustment.

[0038] The exterior of airbag 2 5 contacts the exterior of one of the extension sleeves 6, and the exterior of airbag 2 contacts the exterior of the other extension sleeve 6. Multiple receiving holes 7 are provided inside the two extension sleeves 6. These receiving holes 7 are located inside the extension sleeves 6 and are used to slide and connect the air supply pipe 4, ensuring that the air supply pipe 4 moves synchronously when the spacing of the extension sleeves 6 is adjusted. This maintains the smooth flow of gas and prevents the air supply pipe 4 from bending or becoming blocked due to changes in spacing. The exterior of the air supply pipe 4 is slidably connected to the interior of the receiving holes 7. Multiple cavities 1 8 are provided inside the two extension sleeves 6. These cavities 1 8 are located inside the extension sleeves 6 and are used to accommodate the adjustment components, providing guiding space for the sliding of the extension plate 10, ensuring stable operation of the adjustment components, and achieving precise adjustment of the spacing of the extension sleeves 6. The interior of the cavity 1 8... The sliding connection has an adjustment component for controlling the distance between the two extension sleeves 6. Sheaths 15 are fixedly connected to the left and right sides of the outside of the drainage tube 1. The sheaths 15 are made of polyurethane and cover the edge area where the drainage tube contacts the skin. The softness and wear resistance of polyurethane disperse the pressure of the drainage tube on the skin and avoid direct pressure on the skin by the edge of the drainage tube, which may cause damage. The drainage tube 1 is made of silicone and the sheaths 15 are made of polyurethane. A protective layer 16 is set on the outside of the drainage tube 1. The protective layer 16 is made of nano-silver antibacterial coating material and continuously releases nano-silver ions to inhibit the growth of bacteria on the surface of the device, reduce the risk of infection in the drainage tube fixation area, and ensure a safe environment for wound healing in patients.

[0039] Reference Figure 4 and Figure 7 The adjustment component includes multiple teeth 9 and an extension plate 10. The multiple teeth 9 are fixedly connected to the inner wall of the cavity 8 and engage with the second teeth 14 to form a spacing locking structure. Fine adjustment is achieved through the densely arranged teeth to ensure that the spacing of the extension sleeves 6 does not shift after it is fixed. The external parts of the multiple teeth 9 are all fixedly connected to the inner wall of the cavity 8. The extension plate 10 is slidably connected to the inside of the cavity 8 and moves in the cavity as the extension sleeves 6 are pushed. It adjusts the spacing between the two extension sleeves 6 by its own extension and contraction. It is the core transmission component of the adjustment component and supports adaptive adjustment according to the width of the patient's skin fixation area. Two cavities 11 are opened on the left and right sides inside the extension plate 10. The cavities 11 are opened inside the extension plate 10 to accommodate the spring 12 and the sliding plate 13, providing space for the sliding plate 13 to slide and ensuring that the engagement and disengagement of the second teeth 14 and the teeth 9 are performed smoothly.

[0040] Two springs 12 are installed inside cavity two 11. One end of each spring 12 is connected to the inner wall of the cavity, and the other end is connected to a sliding plate 13. The elastic restoring force pushes the sliding plate 13 to move, causing tooth two 14 to automatically engage with tooth one 9, thus locking the adjusted spacing and avoiding continuous manual pressing. The sliding plate 13 is slidably connected inside cavity two 11, with tooth two 14 fixed at its top. Pressing the sliding plate 13 disengages tooth two 14 from tooth one 9, and it returns to its original position under the action of the springs 12 after being released. It is a key component in the adjustment assembly to realize the switching of the tooth engagement state. One end of the spring 12 is fixedly connected to the inner wall of the cavity 11, and the other end of the spring 12 is fixedly connected to the outside of the sliding plate 13. The top of the sliding plate 13 is fixedly connected to the tooth 14. The tooth 14 is fixed to the top of the sliding plate 13 and engages with the tooth 9 on the inner wall of the cavity 8. By switching between the engagement and disengagement states, the sliding and locking of the extension plate 10 is controlled, thereby realizing the adjustability and stability of the extension sleeve 6 spacing. The tooth 14 engages with the outside of the tooth 9, and the outside of the tooth 14 contacts the inner wall of the cavity 8.

[0041] Working Principle: When using this painless drainage tube fixation device, the initial state of the device must first be checked to ensure that the silicone material of the drainage tube 1 is undamaged, the polyurethane structure of the sheath 15 is intact and without cracks, and the nano-silver antibacterial coating of the protective layer 16 is evenly covered. At the same time, check that there are no air leaks or bulges on the surfaces of the first airbag 2 and the second airbag 5, that the air supply tube 4 is tightly connected to the receiving hole 7 without bending, that the teeth 9 and 14 of the adjusting component are not deformed or worn, and that the spring 12 is in a natural extension and contraction state. Then, insert the clinically used drainage tube into the drainage tube 1, ensuring that the drainage tube and the drainage tube 1 are coaxially aligned. The silicone material of the drainage tube 1 wraps around the outer wall of the drainage tube with its own flexibility, and the polyurethane sheaths 15 on both sides naturally unfold with the insertion action, covering the edge area where the drainage tube contacts the skin, avoiding direct pressure on the skin by the drainage tube. Next, adjust the distance between the two extension sleeves 6 according to the width of the area of ​​skin to be fixed. During operation, press the sliding plate 13 on the outside of the cavity 11 of the extension sleeve 6. The sliding plate 13 slides into the cavity 11 and compresses the spring 12, which drives the tooth 14 at the top to move downward and disengage from the tooth 9 on the inner wall of the cavity 8. Keep the sliding plate 13 pressed and push one of the extension sleeves 6 along the axial direction of the guide tube 1. The extension plate 10 slides synchronously in the cavity 8, which can be partially extended or completely retracted until the distance between the two extension sleeves 6 matches the width of the skin fixation area. After releasing the sliding plate 13, the spring 12 extends due to the recovery of elasticity and pushes the sliding plate 13 to slide out of the cavity 11. The tooth 14 re-engages with the tooth 9, thus locking the distance between the extension sleeves 6.

[0042] After the spacing is adjusted, based on actual usage needs, such as the size of the patient's wound and the size of the drainage tube 1, a medical inflation device, such as a syringe or a small air pump, is connected to the air inlet valve 3 at the top of the first airbag 2 to inject an appropriate amount of sterile medical air into the first airbag 2, causing it to gradually inflate. Its exterior then comes into close contact with the right-side extension sleeve 6, applying pressure. The gas inside the first airbag 2 is transmitted to the left through multiple air delivery tubes 4. The air delivery tubes 4 slide within the receiving holes 7 of the extension sleeve 6, adjusting their displacement synchronously with the spacing of the extension sleeves 6 to prevent pipe twisting. After the gas enters the second airbag 5, the second airbag 5 inflates synchronously, its exterior coming into close contact with the left-side extension sleeve 6, applying pressure. As the first airbag 2 and the second airbag 5 continue to inflate, they exert opposing forces on the left and right extension sleeves 6 respectively, causing the extension sleeves 6 to tighten towards the center, thereby squeezing the drainage tube 1. The drainage tube 1, utilizing the flexible properties of the silicone material, clamps and fixes the internal drainage tube to the patient's skin surface. Throughout the entire process, the nano-silver antibacterial coating of the protective layer 16 continuously exerts its antibacterial effect, inhibiting bacterial growth; the toothed interlocking structure of the adjusting component ensures the stability of the spacing of the extension sleeve 6, preventing displacement; the sliding connection between the gas delivery tube 4 and the receiving hole 7 adapts to changes in spacing, ensuring smooth gas transmission; the flexible expansion of airbag 1 2 and airbag 2 5 evenly distributes pressure, avoiding pain caused by local compression, ultimately achieving painless and stable fixation of the drainage tube.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
