Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a visual gastric tube nasal strip. Background Technology
[0002] The functions of a gastric tube include nutritional support, drug delivery, gastrointestinal decompression, measurement of drainage volume, and monitoring of intragastric pressure. Gastric tubes are usually inserted through the nasal cavity and then need to be secured at the nose.
[0003] Existing gastric tube fixation technologies and products have the following problems:
[0004] 1. Non-transparent dressings: Traditional gastric tube fixation tapes or dressings are mostly made of opaque materials (such as ordinary tape or cotton dressings), which makes it impossible to observe the pressure on the nasal mucosa and surrounding skin in real time, and can easily lead to missed diagnosis of pressure injuries.
[0005] 2. Unstable fixation: The gastric tube is fixed by repeatedly wrapping it with adhesive tape, which is prone to coming loose due to patient activity, sweating or skin oil, requiring frequent replacement (1-2 times a day), increasing the workload of nursing care.
[0006] 3. Lack of pressure buffer: The gastric tube directly compresses the nasal mucosa and skin, which can easily cause pressure injury with long-term use, especially for the elderly, malnourished patients or patients with long-term tubes.
[0007] In the prior art, the following similar products are used:
[0008] 1. Ordinary medical tape: It needs to be pasted and fixed multiple times, which can easily cover the skin and has poor breathability.
[0009] 2. Silicone gastric tube fixation device: Some products contain soft padding, but lack a visual design and rely on rigid buckles for fixation, resulting in insufficient comfort.
[0010] 3. IV3000 transparent dressing: It only provides waterproof protection and is not optimized for dispersing pressure from the gastric tube. It is prone to curling at the edges due to the traction of the gastric tube. Utility Model Content
[0011] The purpose of this invention is to provide a visual nasal strip for gastric tubes that can be adapted to gastric tubes of different diameters, making it convenient to observe the condition of the nasal mucosa and skin and reducing the risk of pressure injury.
[0012] To achieve the above objectives, the present invention provides the following technical solution:
[0013] A visual gastric tube nasal strip includes a silicone pad layer with integrated butterfly-shaped fixing wings at both ends. A TPU film is adhered to the top of the silicone pad layer, and a hydrocolloid adhesive layer is provided below the silicone pad layer, corresponding to the outer area of the TPU film. A backing paper is adhered to the side of the hydrocolloid adhesive layer away from the silicone pad layer, and a silicone clip is adhered to the side of the silicone pad layer.
[0014] Furthermore, there are two backing papers, which are arranged symmetrically, and each backing paper has an easy-tear notch at both corners.
[0015] Furthermore, the silicone buckle has two symmetrical slots inside.
[0016] Furthermore, a gastric tube channel is pre-reserved at the center of the TPU film.
[0017] In summary, the beneficial technical effects of this utility model are as follows:
[0018] 1. The TPU film is transparent at the nasal mucosa, making it easy to observe the condition of the nasal mucosa and detect redness or damage at an early stage.
[0019] 2. The soft padding layer cushions the pressure of the gastric tube on the nasal mucosa, reducing the risk of pressure injury.
[0020] 3. The backing paper is easy to tear off and can be pasted with one hand.
[0021] 4. Install silicone clips with internal slots to accommodate gastric tubes of different diameters. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-3 This utility model provides a technical solution: a visual gastric tube nasal patch, including a silicone pad layer 1, with butterfly-shaped fixing wings 2 integrally set at both ends of the silicone pad layer 1, a TPU film 3 bonded to the top of the silicone pad layer 1, a hydrocolloid adhesive layer 4 provided below the silicone pad layer 1, the hydrocolloid adhesive layer 4 corresponding to the outer area of the TPU film 3, a backing paper 5 bonded to the side of the hydrocolloid adhesive layer 4 away from the silicone pad layer 1, and a silicone buckle 6 bonded to the side of the silicone pad layer 1. The silicone buckle 6 is bonded and fixed to the silicone pad layer 1, and the position of the silicone buckle 6 remains unchanged after fixing.
[0030] In this embodiment, from top to bottom, there are TPU film 3, silicone pad layer 1, and hydrocolloid adhesive layer 4, which takes into account both visibility and pressure dispersion.
[0031] The TPU film is made of medical-grade polyurethane material. The surface of the TPU film 3 is coated with a hydrophilic anti-fog layer to prevent breathing moisture from obstructing the view. Due to its high transparency and high breathability, it is easy to observe the skin condition. At the same time, the TPU film 3 covers the nasal mucosa contact area.
[0032] The hydrocolloid adhesive layer 4 uses a hypoallergenic hydrocolloid backing adhesive, which is breathable and can be repeatedly pasted, maintaining its adhesion for 3-7 days. Two backing papers 5 are also provided, which are symmetrically arranged. Each backing paper 5 has easy-tear notches 7 at the two corners, so that nurses can operate with one hand and reduce skin traction damage when changing it.
[0033] The silicone clip 6 has two symmetrical slots 8 for attaching the gastric tube. The silicone is also elastic, which allows it to hold gastric tubes of different sizes.
[0034] In this embodiment, a gastric tube channel 9 is reserved in the center of the TPU film 3 to avoid contamination or uneven edges caused by on-site cutting by nurses.
[0035] The working principle of this utility model is as follows: by tearing off the backing paper 5, the butterfly-shaped fixing wings 2 are pasted on both sides of the nostrils. The TPU film 3 in the middle covers the nasal mucosa contact area. When pasting, the gastric tube can be locked inside the silicone buckle 6 after being placed and pressed, without the need for additional fixation.
[0036] In this embodiment, based on simulated pressure test data, the silicone pad layer 1 reduces the pressure on the nasal mucosa by 40%-60%, and extends the adhesive retention time from the traditional 1 day to 3-7 days, reducing consumable consumption. At the same time, the transparent design avoids frequent removal of the dressing for inspection, shortening the single operation time by 50%.
[0037] Specifically, silver ion antibacterial agents and hyaluronic acid can be added to the hydrocolloid adhesive layer to reduce the risk of infection and protect delicate skin.
