Abstract
Description
Technical Field
[0001] The invention relates to the technical field of gastrointestinal decompression tubes, in particular to a novel gastrointestinal decompression tube fixing device. Background Art
[0002] A gastrointestinal decompression tube is a commonly used medical device in clinical practice, primarily used to relieve pressure within the gastrointestinal tract or to help expel gas, fluid, and other contents. It is typically inserted through the nasal cavity, through the esophagus, and into the stomach or intestines. It is suitable for patients with gastrointestinal dysfunction, gastrointestinal bleeding, intestinal obstruction, and those recovering from gastrointestinal surgery.
[0003] The common practice of using medical tape to secure gastrointestinal decompression tubes to the nose, while offering good adhesion and convenience, can cause skin allergies or irritation with prolonged use, particularly in patients with sensitive skin. Medical tape typically utilizes pressure-sensitive adhesive technology, which relies on the adhesive's inherent adhesion to firmly adhere to the skin surface without the application of heat or pressure. While this type of tape is convenient and quick to use, prolonged application can lead to moisture imbalances on the skin's surface, impacting normal hydration. The skin serves as the body's natural barrier, with its stratum corneum primarily responsible for protecting the body from water loss and preventing the ingress of harmful external substances. When tape is left attached to the skin for extended periods, the adhesive's adhesion weakens the integrity of the stratum corneum, compromising its protective function. The adhesive components and friction on the tape surface gradually damage the stratum corneum during daily contact. In particular, when the tape is removed, it removes some epidermal cells, further exacerbating barrier damage and increasing the skin's sensitivity to external stimuli. Furthermore, the adhesion of the tape restricts the skin's normal evaporation, preventing it from properly excreting and regulating moisture. This leads to dryness and dehydration, increased fragility, and a weakened skin barrier's ability to repair itself. Furthermore, prolonged tape adhesion can affect blood circulation around the skin, slowing local blood flow and slowing cell metabolism, further limiting recovery. This inefficient circulation exacerbates the skin's nutrient deficiency, further impacting local immunity and creating favorable conditions for the invasion of bacteria and pathogens.

[0016] (3) Beneficial effects
[0017] Compared with the prior art, the present invention provides a novel gastrointestinal decompression tube fixing device, which has the following beneficial effects:
[0018] 1. This new gastrointestinal decompression tube fixation device is set up using a nasal fixation mechanism. The decompression tube passes through the channel and is inserted into the patient's nasal cavity. The inner support block uses a needle to pierce the upper hollow cavity and the lower annular hollow cavity to inject air. The upper hollow cavity is located at the upper part, controlling the expansion of the upper part to contact the top of the nasal cavity; the lower annular hollow cavity is located at the lower part, controlling the expansion of the lower part to fit the bottom of the nasal cavity to achieve stable support. The semi-ring injection point expands the semi-ring hollow cavity by injecting air to provide external support. The internal and external bidirectional support design is balanced and comfortable. The inflation process is simple and suitable for different scenarios. It uses flexible TPE material with strong biocompatibility to ensure that it is non-irritating to the nasal cavity and skin during long-term use and has antibacterial properties, avoiding skin allergies, irritation and damage caused by using tape fixation.
[0019] 2. This new gastrointestinal decompression tube fixing device utilizes a head support mechanism to clip the external decompression tube into the tube slot. The flexible headband is worn on the head using the Velcro loop and hook surfaces, allowing for quick and easy fixation of the decompression tube. When lying down to sleep, the flexible headband is attached to the bed using a flexible magnetic patch. The flexible headband and bed surface are connected via the flexible magnetic patch, reducing slippage during sleep. This prevents the headband from becoming loose or shifting at night, potentially affecting sleep quality.
[0020] 3. This new gastrointestinal decompression tube fixation device utilizes a head support mechanism that allows for quick and easy attachment of the decompression tube to the head, or it can be conveniently hung on the bed. This provides patients with a convenient, independent donning and removal experience, reducing complex installation steps. This design is suitable for bedridden patients and any scenario requiring a fixation device. For example, for patients who have just undergone surgery or require airway therapy, this fixation method allows them to wear the device for extended periods without affecting their sleep or causing discomfort.
[0021] 4. This new gastrointestinal decompression tube fixing device utilizes a bag-fixing mechanism. When it's inconvenient to hold the drainage bag in your hand while going to the bathroom, you can press the buckle, remove the chain, and pass the hanging ring through a suitable section of the chain. Through multiple sections of the chain, the hanging ring can be freely adjusted to the appropriate position as needed, allowing the drainage bag to be securely hung in different environments, avoiding problems such as bag displacement and pulling. Especially for patients with a large range of motion, the stable locking design can effectively prevent the drainage bag from accidentally falling or uncomfortable displacement, helping to improve patients' independence and quality of life.

[0031] 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.
[0032] See also Figure 1 - Figure 8 A new type of gastrointestinal decompression tube fixing device includes a decompression tube 1; a drainage bag 2: the drainage bag 2 is arranged on one side of the decompression tube 1, and the drainage bag 2 is used to collect gastrointestinal fluid, gas and other contents discharged from the decompression tube 1, and ensure that these contents are effectively drained and stored to avoid affecting the patient's health or causing other complications; a nasal fixing mechanism 3: the nasal fixing mechanism 3 is arranged on the decompression tube 1, and the nasal fixing mechanism 3 is used to stably fix the decompression tube 1 inserted into the nostrils, and is used to replace the fixing effect of medical tape, ensuring that the decompression tube 1 does not move or fall off during use, thereby maintaining the decompression effect and avoiding the problem of the tube being stuck. Discomfort or injury caused by displacement; head support mechanism 4: the head support mechanism 4 is arranged on the decompression tube 1, and the head support mechanism 4 is used to fix the middle part of the decompression tube 1 on the head, ensuring that the decompression tube 1 is stable and does not shift in the patient's head area, thereby reducing the patient's discomfort in use and maintaining the correct position of the tube, avoiding pulling or displacement of the tube; bag fixing mechanism 5: the bag fixing mechanism 5 is arranged on the drainage bag 2, and the bag fixing mechanism 5 is used to connect and fix the drainage bag 2 when getting up, ensuring that the drainage bag 2 maintains a stable position during the patient's activities, preventing the drainage bag 2 from shifting or falling off due to movement, thereby ensuring the continuity and safety of drainage.
[0033] The nose fixing mechanism 3 includes an outer supporting semi-ring 31, and the outer wall of the outer supporting semi-ring 31 is provided with a semi-ring injection point 32, which is used to facilitate finding the position for injecting air into the outer supporting semi-ring 31. The outer wall of the outer supporting semi-ring 31 is fixedly connected to one end of a flexible connecting strip 33, and the other end of the flexible connecting strip 33 is fixedly connected to an inner supporting block 34. A pipe through hole 35 is provided on the inner wall of the inner supporting block 34, and the pipe through hole 35 is used to be passed through by the decompression tube 1. A semi-ring hollow cavity 36 is provided on the inner wall of the outer supporting semi-ring 31, and the semi-ring hollow cavity 36 is used to seal and store air. An upper hollow cavity 37 is provided on the inner wall of the inner supporting block 34, and upper and lower annular hollow cavities 38 are provided on the inner wall of the inner supporting block 34. A lower injection point is provided on the outer wall of the inner supporting block 34 39. An upper injection point 310 is provided on the outer wall of the inner support block 34. The outer support half ring 31 and the inner support block 34 are thermoplastic polyurethane elastomer self-healing material TPU. TPU is a material with good elasticity and wear resistance, and has self-healing properties. Its principle is usually based on chemical cross-linking and dynamic interaction between molecules. Through microscopic molecular connections, it can automatically recover after being damaged. The molecular chains in TPU have certain dynamics and flexibility. Punctures or cracks can cause the molecular chains to break or partially decompose. The molecular chains can be reassembled to restore their original shape, thereby restoring the sealing effect. The material can maintain sealing during long-term use to avoid leakage or loss of function due to small holes or cracks. It is used to fix medical catheters, airbag devices, and protect The nasal cavity is slightly punctured and can still maintain air pressure and effective function. When the inner support block 34 needs to fit tightly to the nasal cavity for fixation, it is only necessary to use a needle to pierce the injection point 310 and the lower injection point 39 to inject air into the upper hollow cavity 37 and the lower annular hollow cavity 38, so that the inner support block 34 expands to support and fix the nasal cavity, and at the same time squeeze and fix the inner pressure relief tube 1. The upper hollow cavity 37 and the lower annular hollow cavity 38 are arranged up and down. The upper hollow cavity 37 is located at the upper part of the inner support block 34, and the upper part of the inner support block 34 is controlled to expand so that it can better contact the top of the nasal cavity. The lower annular hollow cavity 38 is located at the lower part of the inner support block 34, and the lower part of the inner support block 34 is controlled to expand so that it can fit tightly with the bottom of the nasal cavity. It provides more precise support force, ensuring that the inner support block 34 can better fit the shape of the nasal cavity, thereby reducing discomfort. Then, air is injected into the semi-annular hollow cavity 36 through the semi-annular injection point 32, so that the semi-annular hollow cavity 36 expands to provide corresponding support to the outside of the nose, forming a two-way support effect with the internal support block 34. This design that takes both inside and outside into consideration not only ensures the stability of the device, but also can evenly fit the inside and outside of the nasal cavity, reducing discomfort. Inflation is completed by acupuncture injection without complicated operations, and is suitable for different application scenarios. It uses a flexible TPE material with strong biocompatibility to ensure that it is non-irritating to the nasal cavity and skin, and has antibacterial properties for long-term use. There are two inner support blocks 34, and the two inner support blocks 34 are symmetrically arranged.The inner support block 34 is used to be placed inside the nostrils. Two inner support blocks 34 correspond to two nostrils. When the nostril is needed, the corresponding inner support block 34 is inserted. The outer support half ring 31 adopts a ring-shaped design to fit tightly to the outside of the nose.
[0034] The head support mechanism 4 includes a flexible headband 41. The surface of the flexible headband 41 is provided with a pipeline card slot 43. The pipeline card slot 43 is provided with a plurality of arrays. The pipeline card slot 43 is used to clamp the decompression tube 1 to prevent slipping and facilitate flexible adjustment of the pipeline. The outer wall of the flexible headband 41 is provided with a Velcro ring surface 44. The outer wall of the flexible headband 41 is provided with a Velcro hook surface 45 to facilitate the quick wearing of the flexible headband 41. The flexible headband 41 is made of elastic material, which can improve the wearing stability and comfort of the device. Flexible support strips 42 are provided on both sides of the flexible headband 41. The area at the edge is relatively small, and the force is concentrated. This force concentration effect causes the same tensile force to produce a greater pressure at the edge, causing excessive pressure on the skin. The flexible support strip 42 is used to prevent the edge of the flexible headband 41 from causing excessive pressure on the skin, thereby improving the wearing experience. The outer wall of the flexible headband 41 is fixedly connected to a flexible magnetic patch 46, which is used to stick to the bed. When sleeping, the flexible headband 41 can be stuck to the bed through the flexible magnetic patch 46. The flexible headband 41 and the bed surface are connected by the flexible magnetic patch 46, reducing the slippage of the headband during sleep. This can prevent the headband from loosening or shifting at night and affecting the use effect.
[0035] The bag fixing mechanism 5 includes a fixing head 51, which is fixedly connected to the top of the pipeline slot 43. A chain 52 is fixedly connected to the fixing head 51. A hanging ring 53 is provided on the drainage bag 2. A buckle 54 is rotatably connected to the hanging ring 53. The buckle 54 and the hanging ring 53 are connected by a spiral spring 55. The spiral spring 55 drives the buckle 54 to tightly contact the hanging ring 53. The pipeline slot 43 is made of flexible magnetic material, which is used for the chain 52 to be adsorbed on the pipeline slot 43 for storage when it is not in use. When you need to go to the bathroom, you can press the buckle 54 to remove the chain 52 and pass the hanging ring 53 through a suitable section of the chain 52. Through multiple sections of the chain 52, the hanging ring 53 can be freely adjusted to a suitable position as needed.
[0036] In summary, the new gastrointestinal decompression tube fixing device passes the decompression tube 1 through the pipe through hole 35, reserves a sufficient length, and then inserts it into the patient's nasal cavity, and then stuffs the inner support block 34 into the nasal cavity, uses a needle to pierce the injection point 310 and the lower injection point 39 to facilitate the injection of air into the upper hollow cavity 37 and the lower annular hollow cavity 38, so that the inner support block 34 expands to support and fix the nasal cavity, and at the same time squeezes and fixes the inner decompression tube 1, the upper hollow cavity 37 and the lower annular hollow cavity 38 are arranged up and down, the upper hollow cavity 37 is located at the upper part of the inner support block 34, and the upper part of the inner support block 34 is controlled to expand so that it can better contact the top of the nasal cavity, and the lower annular hollow cavity 38 is located at the lower part of the inner support block 34, and the inner support block is controlled to expand. The lower part of 34 expands to fit tightly with the bottom of the nasal cavity, which can provide more precise support and ensure that the inner support block 34 can better fit the shape of the nasal cavity, thereby reducing discomfort. Then, air is injected into the semi-circular hollow cavity 36 through the semi-circular injection point 32, so that the semi-circular hollow cavity 36 expands to provide corresponding support to the outside of the nose, forming a two-way support effect with the internal support block 34. This design that takes both inside and outside into consideration not only ensures the stability of the device, but also can evenly fit the inside and outside of the nasal cavity, reducing discomfort. Inflation is completed by acupuncture injection without complicated operations, and is suitable for different application scenarios. It uses a flexible TPE material with strong biocompatibility to ensure that it is non-irritating to the nasal cavity and skin, and has antibacterial properties for long-term use.
[0037] The external pressure-reducing tube 1 is clipped into the tube slot 43, and the flexible headband 41 is put on the head using the Velcro loop 44 and Velcro hook 45. This allows for quick and easy fixation of the pressure-reducing tube 1 on the head. When lying down to sleep, the flexible headband 41 is attached to the bed using the flexible magnetic patch 46. The flexible headband 41 is connected to the bed surface via the flexible magnetic patch 46, reducing the headband's slippage during sleep. This prevents the headband from becoming loose or shifting during sleep, which could affect the wearer's experience.
[0038] The decompression tube 1 can be quickly and easily fixed to the head or conveniently hung on the bed. This provides patients with a convenient independent donning and removal experience, reducing the complex installation steps. This design is suitable for bedridden patients and any other scenarios requiring a fixed device. For example, for patients who have just completed surgery or require airway treatment, this fixation method allows them to wear the device for extended periods without affecting their sleep or causing discomfort.
[0039] When it is inconvenient to hold the drainage bag 2 in hand when going to the bathroom, the user can press the buckle 54 to remove the chain 52 and pass the hanging ring 53 through a suitable section of the chain 52. Through the multiple sections of the chain 52, the hanging ring 53 can be freely adjusted to the appropriate position as needed, helping patients adapt to different body shapes, activity requirements, and treatment conditions. This makes the system more adaptable and can meet various needs. When the buckle 54 is released, the buckle 54 and the hanging ring 53 are in conflict under the action of the spiral spring 55, so that the hanging ring 53, the buckle 54 and the chain 52 are locked. By matching the hanging ring 53 and the buckle 54, the rebound force of the spiral spring 55 is used to achieve a stable lock, so that the drainage bag 2 can be firmly hung in different environments, avoiding problems such as displacement or pulling of the drainage bag 2. Especially for patients with a large range of movement, the stable locking design can effectively prevent the drainage bag 2 from accidentally falling or uncomfortable displacement, helping to improve the patient's independence and daily quality of life.
