Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a nasal catheter fixing protection suit, which aims to improve the comfort of patients and the stability of nasal catheter fixing and protect the nose wings and facial skin of patients. Background Art

[0002] Nasal cannula is one of the commonly used devices in the medical field and is widely used in treatment processes such as digestive fluid drainage, drug infusion, and nutrient input. However, there are some problems with the traditional way of fixing nasal cannula, such as using tape to directly fix the cannula to the skin of the nose. Adhesive tape fixation can easily cause skin allergies, resulting in symptoms such as redness, swelling, and itching. In severe cases, it may even cause skin damage and infection. In addition, due to the lack of stability of adhesive tape fixation, the nasal cannula is easy to fall off when the patient is active, affecting the treatment effect.

[0003] In addition, patients usually use nasal cannulas for gastrointestinal drainage or nutritional infusion, which usually have a long treatment period. The cannulas are usually placed on the left and right sides of the cheeks and fixed, which may cause stress in a fixed direction for a long time, thus causing risks such as pulling and compressing the nose, and easily causing pressure damage to the nose.

[0004] Therefore, it is necessary to improve the traditional nasal catheter fixation method to improve the patient's comfort and the stability of catheter fixation. Utility Model Content

[0005] The utility model provides a nasal catheter fixing and protecting suit, which is composed of a nose wing fixing and protecting device and an ear-hanging free fixing device; wherein:

[0006] The nose wing fixing and protecting device is a butterfly wing annular patch, and both sides of the nose wing fixing and protecting device are provided with nose wing silicone patches that fit on the nose wing and the skin around the nose wing near the cheek, and the nose wing silicone patches are densely covered with air holes, and the nose wing silicone patches are provided with a first catheter card slot,

[0007] Between the nose wing silicone patches on both sides are connected the columella protection patch and the philtrum protection patch which are spaced apart. The columella protection patch is adhered to the surface skin of the columella and the two ends are connected to the nose wing silicone patches in one piece. The philtrum protection patch is adhered to the surface skin of the philtrum and the two ends are connected to the nose wing silicone patches in one piece.

[0008] The ear-hanging free fixing device is a "C"-shaped ear-hanging soft silicone open ring, and the upper outer side wall of the ear-hanging soft silicone open ring is provided with a second catheter clamping groove.

[0009] Furthermore, both ends of the columella protective patch extend 0.5 cm into the nasal cavities on both sides, and one end of the nose wing silicone patch is pasted in the nasal cavity and connected integrally with the columella protective patch.

[0010] Furthermore, the first catheter slot is arranged on the outer side of the nose wing of the nose wing silicone patch.

[0011] Furthermore, the columella protective patch, philtrum protective patch and butterfly-wing-shaped ring patch are all adhered to the skin through hydrogel.

[0012] Furthermore, the first conduit slot and the second conduit slot are both semi-wrapped strip slots, and the opening widths at both ends of the first conduit slot and the second conduit slot are greater than the opening width in the middle.

[0013] The advantages of the utility model are:

[0014] 1. Improve patient comfort: The traditional method of fixing nasal cannula with adhesive tape can easily cause skin allergies, redness, itching, and even skin damage.

After catheterization, this product can increase the force area between the catheter and the skin, disperse the pressure, and reduce local pressure. It reduces the risk of pressure injury to the nasal wing; and reduces the friction between the catheter and the skin. It reduces the risk of redness, swelling, blisters, and allergies caused by the friction between the catheter and the skin. Overall, it reduces the risk of damage to the integrity of the nasal skin due to long-term catheterization.

[0015] 2. Improve the stability of catheter fixation: The nasal catheter fixing and protection kit of the utility model is designed with two parts: a nose wing fixing and protection device and an ear-hanging free fixing device. The nose wing fixing and protection device fixes the nasal catheter at the nose wing through the nose wing silicone patch and the first catheter slot, and the ear-hanging free fixing device fixes the nasal catheter to the ear through the second catheter slot. The two parts work together to greatly improve the stability of nasal catheter fixation, reduce the possibility of catheter falling off, and effectively avoid the risk of unplanned extubation caused by the tape falling off due to sweating in the traditional fixing method.

[0016] 3. Adapt to different nose shapes: The nose wing fixing and protection device of the utility model adopts a butterfly-wing-shaped annular patch design, which can adapt to nose wings of different shapes, making the fixation more fitting.

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0030] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0031] The utility model provides a nasal catheter fixing and protecting suit, which consists of a nose wing fixing and protecting device 100 and an ear-hanging free fixing device 200.

[0032] Nose wing fixed protection device 100

[0033] like Figure 3 The nose wing fixing and protecting device 100 is a butterfly wing annular patch, and both sides of the nose wing fixing and protecting device 100 are provided with nose wing silicone patches 110 that fit on the nose wing and the skin around the nose wing near the cheek, as shown in FIG. Figure 5 As shown, the nose wing silicone patch 110 is densely covered with ventilation holes to help the skin dissipate heat. The nose wing silicone patch 110 is provided with a first catheter slot 111 on the outer side of the nose wing of the nose wing silicone patch 110. The first catheter slot 111 can fix the catheter part of the nasal catheter.

[0034] The nose wing silicone patch 110 is made of a soft material with good elasticity and viscosity, and can fit tightly on the nose wing and surrounding skin without falling off. At the same time, the air hole design of the nose wing silicone patch 110 can effectively prevent skin moisture and keep the skin dry and comfortable. The design of the first catheter slot 111 can be adaptively adjusted according to nasal catheters of different specifications to ensure that the nasal catheter is stably fixed in the nose wing fixing and protection device 100 and is not easy to fall off or move.

[0035] In addition to the nose wing silicone patch 110, the nose wing fixing and protecting device 100 also includes a nose columella protection patch 120 and a philtrum protection patch 130, such as Figure 5 and Figure 7 As shown. The columella protection patch 120 and the philtrum protection patch 130 are connected between the nasal wing silicone patches 110 on both sides. The columella protection patch 120 is adhered to the surface skin of the columella and the two ends are integrally connected to the nasal wing silicone patches 110. The philtrum protection patch 130 is adhered to the surface skin of the philtrum and the two ends are integrally connected to the nasal wing silicone patches 110. The columella protection patch 120 is used to protect the columella from being compressed by the nasal catheter to avoid pain and discomfort. The philtrum protection patch 130 is adhered to the philtrum to increase the stability of the nose wing fixing protection device 100 to prevent it from shifting or falling off.

[0036] The nasal wing silicone patch 110, the columella protection patch 120, and the philtrum protection patch 130 are medical-grade silicone, which is non-irritating to the skin and has good breathability to ensure skin comfort. In addition, the columella protection patch 120, the philtrum protection patch 130, and the butterfly-wing ring patch are all adhered to the skin through hydrogel. Cut the size of the nasal wing silicone patch 110 according to the patient's condition, tear off the adhesive backing paper, use the columella protection patch 120 as the center, determine the position, and gently cover the nasal wing silicone patch 110 on both sides on the nose for sticking. After the catheter is placed, the catheter can be directly inserted into the groove according to the length left outside for fixing, without the need for another person or preparing tape in advance.

[0037] Silicone products are durable and can be replaced once a month if the patient needs long-term catheterization, with less wear and tear. However, traditional tapes are highly irritating and need to be replaced frequently (hypoallergenic tapes are expensive and have greater wear and tear). They have poor stickiness after sweating and pose a high risk of unplanned catheter removal. In addition, tape residues are difficult to clean, and it is difficult to operate while protecting the local skin and ensuring that the catheter position does not shift.

[0038] When sweating, the silicone patch 110 on both sides of the nose wing can be lifted to clean the skin of the nose wing. Since the columella protection patch 120 has the function of fixing the overall position of the product, the position of the product relative to the nose remains unchanged when the silicone patch 110 on one side of the nose wing is lifted, protecting the nose wing fixing protection device 100 from displacement as a whole. When cleaning the skin of the nose wing, the skin on the side without the tube can be cleaned first, and then the tube can be operated after it is pasted back to the original position. During the operation, the catheter can still be stuck in the groove, because the catheter groove is located at the nostril and the edge of the nose wing, so when cleaning the nose wing, this part can be avoided.

[0039] The inside of the nose is made of hydrogel, which absorbs water and swells, has good viscosity, and can be used repeatedly. This part of the hydrogel double-sided patch can also be replaced once a week to maintain the viscosity of the nose part and further reduce the possibility of the device slipping off.

[0040] Preferably, both ends of the columella protection patch 120 extend 0.5 cm into the nasal cavities on both sides, and one end of the nose wing silicone patch 110 is pasted in the nasal cavity and connected integrally with the columella protection patch 120 .

[0041] Ear-hanging free fixing device 200

[0042] like Figure 8 and Fig. 9 As shown, the ear-hanging free fixing device 200 is a "C"-shaped ear-hanging soft silicone open ring, which can be passed around the patient's ear to fix the ear-hanging free fixing device 200 on the head. The upper outer side wall of the ear-hanging soft silicone open ring is provided with a second catheter clamping groove 211, and the second catheter clamping groove 220 can fix the catheter part of the nasal catheter to prevent the nasal catheter from shifting or falling off when the head moves.

[0043] The material of the ear-hanging soft silicone open ring has a certain elasticity and can be adjusted according to the head shape of different patients to ensure the stability and comfort of the ear-hanging free fixing device 200. The design of the second catheter slot 220 also takes into account the specification differences of nasal catheters and can adapt to nasal catheters of different specifications to ensure the stable fixation of the nasal catheter.

[0044] In the present invention, the first conduit slot 111 and the second conduit slot 211 are both semi-wrapped strip slots, and the opening widths of the first conduit slot 111 and the second conduit slot 211 at both ends are larger than the opening width in the middle. The design of large openings at both ends and small openings in the middle can make it easier to insert the conduit 210 (such as Fig. 9 ) is inserted into the first catheter slot 111 and the second catheter slot 211, and the nasal catheter can be ensured to be stable in the slot without slipping. In addition, the semi-wrapped design can fix the nasal catheter without completely wrapping the nasal catheter, ensuring the ventilation of the nasal catheter, preventing the dampness and stuffiness caused by being wrapped for a long time, and further improving the comfort of the patient.

[0045] In summary, the nasal cannula fixing and protection kit of the utility model realizes the dual fixation of the nasal cannula through the combination of the nose wing fixing and protection device and the ear-hanging free fixing device, effectively improves the stability of the nasal cannula, and reduces the possibility of the nasal cannula falling off. At the same time, the nose wing fixing and protection device and the ear-hanging free fixing device are both made of medical-grade materials, which are non-irritating to the skin, have good air permeability and comfort, can protect the patient's skin, and improve the patient's use experience. In addition, the nasal cannula fixing and protection kit of the utility model also has the advantages of simple structure, easy use, low cost, etc., and has broad market application prospects.

[0046] The above describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the above-mentioned specific implementation methods, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the utility model without departing from the scope of the technical solution of the utility model, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the utility model.
