Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a medical tubing silicone fixation patch that can be repeatedly peeled and applied without damaging the skin. Background Technology

[0002] In clinical medical care, securely fixing various medical lines, such as indwelling intravenous needles, drainage tubes, and urinary catheters, to the patient's body surface is a crucial step in ensuring smooth treatment and preventing complications. Currently, medical tape or disposable pre-made dressings are commonly used in clinical practice for fixation.

[0003] To ensure effective fixation, these traditional fixation products typically use strong pressure-sensitive adhesives. However, when these strong adhesives are removed, they often peel away the stratum corneum of the skin, causing mechanical damage, pain, redness, and even breakage. This is especially problematic for elderly or infant patients with fragile skin who require long-term catheter placement, as repeated dressing changes significantly increase the risk of skin damage and discomfort.

[0004] To reduce skin irritation, some milder adhesive dressings are available on the market. However, these products often sacrifice adhesion strength, making them prone to curling at the edges and failing to adhere properly when the patient sweats or moves around a lot. This increases the risk of tubing slippage or accidental removal, threatening patient safety. Furthermore, the single-use nature of both strong and mild adhesive dressings means that once torn off for wound observation or repositioning, they cannot be effectively reattached and must be discarded and replaced. This not only wastes medical resources but also increases the workload of medical staff. Therefore, this invention proposes a reusable, skin-friendly medical tubing silicone fixation dressing to address the shortcomings of existing technologies. According to CN209713955U, a silicone tubing fixator includes an adhesive tape, a base fixed to the adhesive tape, and a semi-enclosed slot mounted on the base. The adhesive tape is made of silicone adhesive dressing, allowing for repeated application with minimal residue and less skin damage. However, this solution only achieves fixation with a single adhesive tape, lacking a wrap-around transparent membrane structure for the pre-installed needle hub, and also lacks an adjustable binding system with interlaced binding strips and a textured surface layer, thus failing to achieve dual-segment fixation of the needle hub and tubing. The publication CN209107783U discloses a reusable dressing comprising an elastic support layer and a silicone adhesive layer; the silicone adhesive layer is attached to one side surface of the elastic support layer, possessing self-adhesion and reusability. However, this solution only involves improvements to the adhesive layer structure of the dressing itself, without addressing the fixation of medical tubing or providing dedicated tubing fixation structures (such as arc-shaped grooves, binding strips, etc.). Its application scenario and the technical problems it solves are fundamentally different from those of this application. Meanwhile, publication number CN205994852U discloses a catheter fixation bracket, including a bracket body and an adhesive patch fixed below the bracket body. The adhesive patch comprises, from top to bottom, an adhesive layer, a skeleton layer, and a silicone layer. However, the adhesive patch in this solution uses a composite structure of ordinary adhesive tape and a silicone layer, rather than a fully silicone adhesive layer design, and it does not have a venting structure. Furthermore, this solution does not involve an adjustable fixing structure that combines a binding strip with a textured surface layer, and the method of fixing the tubing differs significantly from that of this application. Summary of the Invention

[0005] In view of the problems in the existing medical tubing fixation adhesive that are difficult to balance with skin protection performance, and that single use leads to inconvenience in adjustment and material waste, the present invention aims to provide a medical tubing silicone fixation adhesive with an improved structure that can be repeatedly peeled and pasted without damaging the skin, effectively solving the above problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a medical tubing silicone fixation patch that can be repeatedly applied and removed without damaging the skin, comprising: As a wrapping for the reserved needle, transparent adhesive strips are fixedly connected around its perimeter. A silicone adhesive layer is fixedly connected to the outer wall of the transparent adhesive strips. An integrally formed gauze layer is fixedly connected to the bottom of the transparent adhesive strips and the silicone adhesive layer. An integrally formed protective tear layer is applied to the bottom of the gauze layer. As a sponge pad for fixing the pipe, the pipe is located in the middle of the sponge pad surface. The middle of the sponge pad has an arc-shaped groove for the pipe to pass through. The inside of the arc-shaped groove is filled with adhesive silicone. Both sides of its surface are provided with a textured layer. One side of the sponge pad is fixedly connected to a second binding strip, and the other side of the sponge pad is fixedly connected to a first binding strip.

[0007] Preferably, the silicone adhesive layer has multiple air pores inside, which penetrate the gauze layer at the same location to enhance air circulation in the skin contact area.

[0008] Preferably, the second binding strip is U-shaped, and the first binding strip passes through the interior of the second binding strip to form a fixing structure that is easy to insert and tighten.

[0009] Preferably, both the second binding strip and the first binding strip are covered with protective strips to protect their adhesive surfaces before use.

[0010] Preferably, the ends of both the second and first binding strips are adhered to the rough surface layer on the opposite side, forming a fastening system that can be repeatedly torn open and closed.

[0011] Preferably, the transparent adhesive strips are 3-5cm in length and 2-4cm in width.

[0012] Preferably, the gauze layer is medical degreased gauze with a warp and weft density of 100-140 threads / 10cm and a thickness of 0.3-1mm.

[0013] Preferably, both the protective tear layer and the protective strip are release paper or release film, with their surfaces coated with silicone oil release agent and a release force of 5-30g / 25mm, to ensure that they can be easily torn off without damaging the adhesive layer during use.

[0014] A method for using a reusable, skin-friendly medical tubing silicone adhesive patch includes the following steps: Step 1: Cover the puncture site of the pre-inserted needle on the patient's skin with a transparent film, so that the needle hub and part of the tubing of the pre-inserted needle are wrapped in the transparent film. Remove the protective tear layer to expose the silicone adhesive layer. Smooth the four transparent adhesive strips outwards and press them onto the patient's skin to make the silicone adhesive layer adhere tightly to the skin, thus completing the initial fixation of the pre-inserted needle. The gauze layer plays a role in breathability, moisture absorption and cushioning, and the silicone adhesive layer allows the skin to breathe through its internal pores.

[0015] Step 2: Place the medical tubing that needs to be fixed onto the adhesive silicone in the center of the sponge pad. Gently press to embed the tubing into the adhesive silicone. The adhesive silicone will create an adhesive force on the tubing, preventing it from sliding. Then, remove the protective strips from the surfaces of the first and second binding strips. Wrap the first binding strip around the tubing from the top to the opposite side, passing it through the U-shaped opening of the second binding strip. Then, pull the first and second binding strips in opposite directions to tighten them, so that their ends are attached to the textured surface on the opposite side. This achieves repeated adhesion and fixation between the binding strips and the sponge pad.

[0016] Step 3: Adjust the position of the sponge pad on the skin according to the routing of the tubing and the patient's position, ensuring that the tubing is not twisted or compressed, and press each adhesive site again to ensure that it is firmly fixed.

[0017] Preferably, when replacement or inspection is required in step three, lift the edge of the transparent adhesive strip or the ends of the first and second binding strips, and slowly tear them off at an angle of 135°-165° to the skin. Re-attach the ends of the binding strips to the fabric surface, and re-attach the transparent adhesive strips to the skin to complete the re-fixation.

[0018] The usage process and working principle of the medical tubing silicone fixation patch that can be repeatedly peeled and applied without damaging the skin provided by this invention are as follows: First, the indwelling needle is secured by covering the puncture site on the patient's skin with a transparent film, encasing the needle hub and part of the tubing. Then, the protective tear layer is removed, exposing the silicone adhesive layer and gauze layer. Four transparent adhesive strips are smoothed outwards and pressed onto the patient's skin. The silicone adhesive layer adheres tightly to the skin, completing the initial fixation of the indwelling needle. The gauze layer provides breathability, moisture absorption, and cushioning, while the silicone adhesive layer allows for skin ventilation through its internal pores that penetrate the gauze layer.

[0019] Next, secure the medical tubing. Place the tubing to be secured on the adhesive silicone in the center of the sponge pad and gently press to embed the tubing into the silicone. The silicone will provide adhesion and prevent the tubing from slipping. Remove the protective strips from the surfaces of the first and second binding strips. Wrap the first binding strip around the tubing from the top to the opposite side, passing it through the U-shaped opening of the second binding strip. Then, pull the first and second binding strips in opposite directions to tighten them, so that their ends are adhered to the textured surface on the opposite side. This allows for repeated adhesion and fixation between the binding strips and the sponge pad 7.

[0020] Depending on the tubing routing and patient position, adjust the placement of the sponge pad on the skin as needed, ensuring the tubing is free from twisting or pressure. Press each adhesive site again to ensure secure fixation. When replacement or examination is required, lift the edge of the transparent adhesive strip or the ends of bandage 1 and bandage 2, and slowly peel it off at a 135°-165° angle to the skin. After the procedure, re-adhere the ends of the bandages to the skin surface and re-attach transparent adhesive strip 2 to the skin to re-secure the tubing.

[0021] This invention provides a medical tubing silicone fixation patch that can be repeatedly applied and removed without damaging the skin. It has the following beneficial effects: 1. This invention uses a silicone adhesive layer combined with a through-hole design, which reduces the peeling damage to the stratum corneum of the skin caused by the excessive stickiness of traditional adhesive patches when they are removed, thus relieving the patient's pain. Furthermore, its good breathability prevents sweat accumulation and reduces the risk of skin maceration and allergies.

[0022] 2. This invention achieves dual and segmented fixation of the infusion system through a split structure of a transparent membrane fixing the needle hub and a sponge pad fixing the tubing. This effectively disperses the stress on the tubing, avoids external traction acting directly on the puncture point, thereby significantly improving the stability and safety of fixation and effectively preventing accidental tubing dislodgement.

[0023] 3. This invention provides a pipe binding solution that is intuitive to operate, adjustable in tightness, and securely fixed by using a U-shaped binding strip on a sponge pad and an interlocking binding strip, combined with a repeatedly adhesive textured surface. This allows for adjustments to the fixing method and adaptability to pipes of different diameters.

[0024] 4. The overall structure of the fixation patch of this invention supports repeated application and removal during treatment. When temporary adjustments or examinations are required, it can be fixed again without replacing consumables, which not only saves medical costs but also provides convenience and flexibility for clinical operation.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example: Please see the appendix Figure 1 - Appendix Figure 5 This invention provides a medical tubing silicone fixation patch that can be repeatedly applied and removed without damaging the skin. It aims to solve the problems of existing medical fixation patches that easily cause skin stratum corneum tearing, redness, swelling and stinging during repeated application and removal, as well as the relatively simple fixation structure for tubing, concentrated force and insufficient stability, and the need to discard the dressing once when adjusting the tubing, resulting in high material consumption.

[0029] This medical tubing silicone fixation tape, which can be repeatedly peeled and applied without damaging the skin, consists of two independent components: a transparent film 1 for wrapping the pre-inserted needle and a sponge pad 7 for fixing the tubing. The two components can be applied separately and adjusted independently without interfering with the puncture point or the tubing route.

[0030] Four symmetrically distributed transparent adhesive strips 2 are integrally fixed to the four sides of the transparent membrane 1. A medical low-sensitivity silicone adhesive layer 3 is integrally fixed to the outer wall of the transparent adhesive strips 2. A gauze layer 6 is integrally pressed and pressed to the bottom of the transparent adhesive strips 2 and the silicone adhesive layer 3. An integrally formed protective tear layer 5 is completely applied to the bottom of the gauze layer 6. The four transparent adhesive strips extend in four directions: up, down, left, and right. The symmetrical structure can evenly distribute the adhesive tension and avoid unilateral traction that may cause the puncture point to shift or the needle seat to lift. The transparent membrane is made of high-transparency medical PVC film with a thickness controlled between 0.08 and 0.15 mm and a light transmittance of ≥92%. Medical staff can directly observe whether there is bleeding, redness, swelling, or leakage of medication at the puncture site without removing the fixing tape, and the observation of the local wound is not interfered with throughout the process.

[0031] The silicone adhesive layer 3 has multiple circular ventilation holes evenly arranged inside, which vertically penetrate the corresponding positions of the gauze layer 6. The pore diameter is uniformly set to 1.2–1.8 mm, and the center-to-center distance between the holes is 3 mm. This densely distributed perforation design can significantly improve skin breathability. Even if the patient wears it for a long time or sweats heavily in summer, it can quickly wick away subcutaneous moisture, preventing skin maceration, eczema, and contact dermatitis caused by sweat-induced stuffiness. The transparent adhesive strip 2 is set to a length of 4 cm and a width of 3 cm. This size is suitable for the needs of adult indwelling needles and PICC dressings. For infant patients, a smaller transparent adhesive strip specification of 2 cm × 1.5 cm can be produced simultaneously to fit the needle holder of small indwelling needles for children.

[0032] The gauze layer 6 is made of medical-grade degreased gauze with a warp and weft density of 100-140 threads / 10cm and a thickness of 0.3-1mm. The gauze undergoes high-temperature degreasing and ethylene oxide sterilization, leaving no fluorescent agents or residual paste, and is soft and skin-friendly to the touch. The multi-layered thin gauze composite structure provides cushioning, shock absorption, and moisture absorption. The silicone adhesive layer does not directly contact the skin, and the gauze layer isolates the silicone, further reducing the probability of allergies in sensitive skin. The protective tear layer 5 is release paper or release film coated with a silicone oil release agent, with a release force of 5-30g / 25mm. It will not tear the silicone adhesive layer during peeling, preventing adhesive loss, and leaves no residue on the silicone surface after removal, ensuring repeated adhesion. A 0.8cm adhesive-free tear handle is provided at the edge of the release paper, allowing for quick and easy removal of the protective layer by hand without the need for tweezers, improving clinical efficiency.

[0033] The sponge pad 7 is used for positioning and securing the tubing. The tubing is positioned in the central area of ​​the sponge pad 7. The center of the sponge pad 7 has a stamped arc-shaped groove adapted to various tubing outer diameters. The inner wall of the arc-shaped groove is rounded and chamfered to avoid sharp edges from squeezing or scratching the outer wall of rigid tubing, which could cause leakage. The groove is 2mm deep and compatible with commonly used clinical tubing such as 1.5–8mm outer diameter indwelling intravenous catheters, abdominal drainage tubes, urinary catheters, and gastric tubes, offering high versatility. A layer of medical-grade adhesive silicone is evenly coated inside the arc-shaped groove. Nylon fleece layers 10 are symmetrically sewn onto both sides of the sponge pad 7. A binding strip 2 9 is heat-pressed and fixed to one side of the sponge pad 7, and a binding strip 1 8 is integrally formed on the other side. The sponge pad is made of high-density open-cell medical-grade polyurethane sponge with a density of 35–45 kg / m³. 3 It has excellent resilience and is not easy to collapse after being compressed, which can buffer the pulling force generated by the tube when the patient moves his / her limbs and reduce the traction pain at the puncture point; the entire sponge is treated with a waterproof and sweatproof coating, so sweat and disinfectant iodine will not penetrate the sponge and breed bacteria.

[0034] The second binding strip 9 is integrally stamped into a U-shape, forming a hollow channel for threading. The first binding strip 8 is threaded laterally through the hollow interior of the second binding strip 9 during use. The width of the U-shaped opening is adapted to the thickness of the first binding strip, ensuring smooth and unobstructed insertion. Medical staff can complete the threading operation with one hand, eliminating the need for two-handed assistance, making it suitable for single-person bedside care. Both the second binding strip 9 and the first binding strip 8 are fitted with matching protective strips at the factory. The material, silicone release agent parameters, and release force index of these protective strips are completely consistent with the protective tear layer 5. The protective strip completely covers the adhesive surface of the binding strip, preventing dust and impurities from contaminating the silicone adhesive surface during storage and transportation, ensuring stable adhesion upon initial use. The edges of the protective strip are rounded to prevent sharp edges from scratching the hands of medical staff or the skin of patients. The ends of both the second binding strip 9 and the first binding strip 8 are Velcro hooks with adhesive silicone, which can be repeatedly attached to the opposite side of the rough surface layer 10, forming a repeatedly tear-open and adjustable binding connection structure.

[0035] In one specific embodiment, the sponge pad 7 used to fix the tubing has an arc-shaped groove in the center of its surface pre-filled with adhesive silicone to provide initial adhesion and positioning when the tubing is placed, preventing the tubing from sliding left or right or coming out of the groove during the binding process. A wide nylon textured surface layer 10 is heat-pressed and fixed to the flat areas on both sides of the arc-shaped groove on the surface of the sponge pad 7. This textured surface layer 10 provides a large, repeatedly adhesive anchoring area for the first binding strip 8 and the second binding strip 9. The textured surface layer is 3cm long and 2cm wide, providing ample adjustment range. The tightness of the binding can be freely adjusted according to the thickness of the tubing and the range of limb movement. For thicker tubing, the binding can be loosened; for thinner tubing, it can be tightened, adapting to the arm, chest, and abdomen of patients of different body types for tubing fixation.

[0036] The second binding strip 9, which is fixedly connected to one side of the sponge pad 7, has an integral U-shaped structure with a hollow channel forming a passageway for the first binding strip to pass through. The first binding strip 8, which is fixedly connected to the other side of the sponge pad 7, has its free end that crosses horizontally over the pipe to be fixed during use and passes directly through the U-shaped opening of the second binding strip 9.

[0037] After insertion, pull the free ends of strap 8 and strap 9 towards the sides of the sponge pad respectively to ensure the tubing is stably compressed and confined within the arc-shaped groove, preventing it from bouncing up and down or shifting left and right. After tightening, attach the hook end of strap 8 to its opposite side, i.e., the rough surface layer 10 near the root of strap 9, and simultaneously attach the hook end of strap 9 to its opposite side, i.e., the rough surface layer 10 near the root of strap 8. This bidirectional pulling completes the closed-loop binding and fixation of the tubing. The bidirectional binding provides balanced force, preventing the problem of one-sided strap loosening. Even when the patient raises their hand or turns over with large limb movements, the tubing will not loosen or slip, significantly reducing the risk of unplanned extubation.

[0038] The component used to wrap the pre-existing needle has a bottom support of gauze layer 6, which is made of medical degreased gauze with a warp and weft density of 100–140 threads / 10cm and a thickness of 0.3–1mm. A silicone adhesive layer 3 is compositely fixed above the gauze layer 6, with multiple evenly spaced vents vertically penetrating the same location within it, providing continuous airflow channels to the skin and preventing suffocation. A transparent adhesive strip 2 extending in four directions from the transparent film 1 has a length limited to 3–5cm and a width limited to 2–4cm; in this embodiment, a standard specification of 4cm long and 3cm wide is preferred.

[0039] The second binding strip 9 is specifically designed as an integrated U-shaped structure, providing a stable path for the insertion of the first binding strip 8. In use, the hook ends of the first binding strip 8 and the second binding strip 9 are glued and fixed to the opposite side of the rough surface layer 10. This hook + rough surface bonding method supports dozens of repeated tearing and pasting operations, and the adhesiveness decays slowly.

[0040] As a dustproof protective structure before use, the protective tear-off layer 5, which is applied to the bottom of the gauze layer 6, and the protective strips, which are attached to the surfaces of the first binding strip 8 and the second binding strip 9, are both based on single-sided silicone-coated release paper or PET release film. The release paper / release film is uniformly coated with silicone oil release agent on one side. The release force parameter required for peeling is strictly controlled within the range of 5–30g / 25mm. If the release force is less than 5g, it will peel off on its own during transportation. If it is more than 30g, the tearing resistance will be too great and the silicone adhesive layer will be easily damaged. This parameter range takes into account both storage stability and ease of operation, and is suitable for the needs of rapid clinical dressing changes and tubing inspections.

[0041] After each removal of the silicone adhesive layer 3, if the surface becomes contaminated with iodine, sweat, or skin flakes, causing a significant decrease in adhesiveness, gently wipe the surface of the silicone adhesive layer 3 with a sterile medical alcohol swab. Allow it to air dry naturally in a ventilated place at room temperature for 1–3 minutes to restore its adhesiveness and allow it to be used again. However, the same silicone adhesive layer 3 should not be repeatedly removed and applied to the same patient more than 50 times. After exceeding the recommended number of times, the silicone adhesive layer molecules will age and the adhesiveness will decrease significantly. In this case, a brand new fixation patch should be replaced to ensure the fixation effect of the tubing and the long-term safety of the skin.

[0042] For patients with newborns, severe edema, eczema, broken skin, or fragile skin due to burns, it is recommended to limit the number of times the patch is removed to 20 times per application to reduce mechanical irritation to the damaged skin from repeated pulling of the silicone. When changing the patch, clean the skin and apply a medical moisturizing and repairing dressing to further reduce the probability of skin damage. If the patient experiences persistent redness, swelling, itching, large patches of rash, stinging, ulceration, or other allergic or uncomfortable symptoms, discontinue use of the patch immediately. After removal, clean the affected skin and consult a healthcare professional for alternative fixation materials.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
