[0027] This utility model provides a silicone gel indwelling needle patch, which is improved in that it includes a recording strip, release paper, polyurethane film layer, microporous silicone gel layer, silicone tape strip and embossed protective layer.

[0028] The release paper is divided into a first part and a second part. The first part of the release paper is pasted on the polyurethane film layer and has an opening in the center. The recording strip is set on the outer surface of the second part of the release paper.

[0029] The embossed protective layer has one surface divided into a first region and a second region. A microporous silica gel layer and a silicone tape strip are respectively attached to the first region and the second region of the embossed protective layer, and a polyurethane film layer is attached to the microporous silica gel layer.

[0030] The recording strip is made of non-woven paper and acrylic adhesive. The polyurethane film layer is 12-20um thick. The microporous silicone gel layer includes multiple pores with a diameter of 0.1-1mm and a spacing of 1-2mm between each pore. The silicone tape strip is made of PE, PU or non-woven silicone gel tape. The embossed protective layer includes silicone tape for auxiliary fixation. The release paper and the embossed protective layer are provided with dotted pre-cut lines.

[0031] The silicone gel indwelling needle patch features a functional zoning and nested design. The recording strip and release paper are placed side by side, with the release paper covering a polyurethane film. The polyurethane film and microporous silicone gel layer extend continuously to the rear end. Silicone tape and embossed protective layer are placed on both sides of the patch. The dotted pre-cuts facilitate operation. This design not only facilitates manufacturing and assembly but also ensures the accuracy and stability of the patch during application. The front end is used to record patient information, the middle part is mainly responsible for direct contact with the skin and providing necessary protection and treatment functions, while the rear end strengthens the fixation effect, ensuring the stability of the indwelling needle patch throughout its entire service life.

[0032] Reference Figure 1-7 As shown, the silicone gel indwelling needle patch includes a recording strip 1, release paper 2, polyurethane film layer 3, microporous silicone gel layer 4, silicone tape strip 5, and embossed protective layer 6.

[0033] Specifically, the release paper 2 is divided into a first part and a second part. The first part of the release paper is pasted on the polyurethane film layer 3. The left side of the first part of the release paper 2 is provided with an opening window 2-1 and an opening protrusion 2-2. The opening protrusion 2-2 facilitates the quick peeling of the release paper, exposing the polyurethane film layer 3 and the microporous silicone gel layer 4 underneath. The right side of the second part is designed with a dotted tangent line 2-3 to facilitate the tearing of the recording strip. The recording strip 1 is made of non-woven paper and acrylic adhesive, which facilitates medical staff to record patient information.

[0034] Specifically, one surface of the embossed protective layer 6 is divided into a first region and a second region, and the microporous silicone gel layer 4 and the silicone tape strip 5 are respectively attached to the first region and the second region of the embossed protective layer 6.

[0035] Specifically, the polyurethane membrane layer 3 has a thickness of 12-20μm and excellent waterproofness and flexibility. The microporous silicone gel layer 4 contains multiple pores with a diameter of 0.1-1mm and a pore spacing of 1-2mm to ensure high air permeability.

[0036] Specifically, the first area of ​​the embossed protective layer 6 is closely attached to the underside of the microporous silicone gel layer 4. The silicone tape strip 5 is made of PE, PU or non-woven silicone gel tape to enhance the fixation effect of the indwelling needle patch. The embossed protective layer 6 is made of PP or PE embossed film, and the surface embossing design increases friction. The second area on the right side of the embossed protective layer 6 has a dotted pre-cut 6-1 to facilitate medical staff to quickly take the silicone tape for auxiliary fixation.

[0037] Specifically, Record Strip 1, located on the top layer, is made of a composite material of non-woven paper and acrylic adhesive. The non-woven paper, with its excellent breathability and softness, reduces pressure on the skin; the acrylic adhesive ensures that the record strip can be firmly adhered to the indwelling needle patch, while also making it easy for medical staff to tear off and record patient information, such as infusion time and medication type, thus improving the efficiency and accuracy of nursing work.

[0038] Release paper 2: Covers the polyurethane film layer as a protective layer to prevent contamination or damage to the polyurethane film layer during storage and transportation. The first part of the release paper 2 has an opening window 2-1 and an opening protrusion 2-2 to facilitate observation of the underlying structure and peeling off the release paper. Meanwhile, the edge of the second part is designed with a dotted tangent line 2-3 to facilitate quick retrieval of the recording strip by medical staff.

[0039] Polyurethane membrane layer 3: With a thickness of 12-20 micrometers, this carefully designed thickness range ensures that the indwelling needle patch has sufficient flexibility to adapt to the skin curves of different sites, while also possessing sufficient strength to prevent damage from friction or pulling during use. The polyurethane material itself has excellent waterproof properties, further enhancing the product's durability and safety.

[0040] Microporous silicone gel layer 4: As the core functional layer, the microporous silicone gel layer contains multiple pores with a diameter of 0.1-1 mm and a spacing of 1-2 mm. This microporous design not only ensures high skin breathability, effectively reducing the risk of dampness and skin inflammation caused by prolonged wear, but also effectively prevents skin infection through the physical barrier effect of the micropores. The material properties of silicone gel also provide good skin affinity, reducing skin irritation caused by residual silicone gel.

[0041] Silicone tape strip 5: Made of PE (polyethylene), PU (polyurethane), or non-woven silicone gel tape material, chosen for their excellent adhesion, breathability, and comfort. The silicone tape strip not only enhances the overall fixation of the indwelling needle patch but also, through its elasticity, better conforms to different skin shapes, reducing the risk of dislodgement due to movement or activity.

[0042] Embossed Protective Layer 6: Located at the bottom, this layer uses PP (polypropylene) or PE embossed film material. The embossed design increases surface friction, further enhancing the stability of the indwelling needle patch. The second area on the right side of the embossed protective layer features silicone tape for auxiliary fixation, providing additional securing options, especially in areas with high activity levels or where skin adhesion is difficult. Furthermore, the embossed design improves wearing comfort, reducing pressure and friction on the skin.

[0043] In the aforementioned process, the design of the microporous silicone gel layer is a major highlight of this invention. It significantly improves the breathability of the indwelling needle patch, effectively alleviating skin dampness caused by prolonged wear and reducing the risk of skin inflammation and infection. This is particularly important for patients requiring long-term infusions, helping to improve their overall treatment experience and comfort. The combination of the polyurethane membrane layer and the microporous silicone gel layer ensures a dry environment inside the indwelling needle patch while preventing the penetration of external liquids (such as sweat and rainwater), thus effectively preventing skin infections caused by liquid leakage. This design enhances product safety and provides additional protection for patient health.

[0044] Furthermore, the thickness of the polyurethane film is controlled between 12 and 20 micrometers. This fine adjustment ensures that the indwelling needle patch is both soft enough to closely conform to various skin shapes, and strong enough to resist damage from daily activities. This balanced design improves the stability and durability of the indwelling needle patch, reducing the inconvenience and cost caused by frequent replacements.

[0045] Furthermore, the design of the recording strips facilitates quick recording of patient information by medical staff, while the choice of non-woven paper and acrylic adhesive ensures clarity and easy tearing. The pre-cut perforated lines on the release paper and embossed protective layer further simplify the operation process, allowing medical staff to easily and accurately tear off the required portion, thus improving work efficiency.

[0046] Furthermore, the selection of materials and structural design of the silicone tape strip and embossed protective layer fully consider patient comfort. The silicone material itself has good skin affinity, reducing skin irritation caused by the indwelling agent; the embossed design increases surface friction, improving fit and stability, while reducing skin discomfort caused by prolonged wear.

[0047] In one embodiment, medical staff first remove the release paper and attach the polyurethane film and microporous silicone gel layer to the patient's puncture site. The recording strip is used to record the patient's infusion information, while the silicone tape strip and embossed protective layer are used to enhance the fixation effect of the indwelling needle patch. The dotted pre-cut design on the release paper and embossed protective layer makes it convenient for medical staff to quickly and accurately take the required parts, improving the ease of operation.

[0048] Compared to existing technologies, this utility model achieves significant improvements in breathability, waterproofness, flexibility, strength, ease of operation, and comfort through a series of innovative designs. These improvements not only enhance the patient's treatment experience and comfort but also reduce the workload of medical staff, thereby increasing the efficiency and safety of nursing care.

[0049] In summary, the silicone gel indwelling needle patch of this invention, with its unique design concept and excellent functional characteristics, provides a safer, more comfortable, and more efficient solution for patients requiring long-term infusion, while also providing medical staff with a more convenient and reliable operating tool.

[0050] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
