Referring to fig. 1-6, an embodiment of the present utility model provides an infant nasal oxygen cannula, which includes a nasal catheter 1, an equipment connector 2, a nasal plug 3 and a fixing device 4; the nasal catheter 1 is connected with the nasal plug 3 and the equipment connector 2; the nasal plug 3 includes a first nasal plug 30 and a second nasal plug 31; the first nasal plug 30 and the second nasal plug 31 are connected in a foldable manner so that the joint can be folded and deformed at any angle; the fixing device 4 is connected with the nasal plug 3, and the fixing device 4 comprises a facial patch 40, and the facial patch 40 is adhered to the face of the infant according to the skin of the infant.

It should be noted that in the prior art, when the nasal oxygen cannula is used for infants, various patches are usually required to be additionally used for fixing the nasal oxygen cannula, the patches are basically made of plastic parts, the elasticity is poor, and the patches are easy to break after being disassembled and assembled for a plurality of times, so that the patches are required to be replaced frequently, and for infants with low coordination degree, the replacement difficulty is high, and the replacement difficulty is not only unfavorable for the health of the infants. Meanwhile, the connecting piece of the facial mask and the nasal oxygen cannula is large in size, so that the facial pressure of an infant is easily increased, and discomfort is easily caused to the infant. In this embodiment, since the first nasal plug 30 and the second nasal plug 31 are connected in a foldable manner so that the connection portion can be folded and deformed at any angle, the fixing device 4 is connected with the nasal plug 3, and the fixing device 4 includes the facial patch 40, the facial patch 40 is adhered to the face of an infant in compliance with the skin of the infant, so that the first nasal plug 30 and the second nasal plug 31 can be adjusted when the nasal oxygen cannula of the infant is worn, so that the first nasal plug 30 and the second nasal plug 31 are better in compliance when being adhered to the face of the infant, the pressure on the face of the infant is reduced, the stability of the nasal oxygen cannula face is improved, and frequent replacement of the patches is avoided.

In some embodiments, the first nasal prong 30 includes a first prong body 300 and a first nasal prong portion 301 at one end of the first prong body 300; the second nasal plug 31 includes a second plug body 310 and a second nasal plug head 311 at one end of the second plug body 310; the first nose plug 301 is connected with the second nose plug 311; the first nose plug-in head 301 and the second nose plug-in head 311 are soft rubber, so that the joint of the first nose plug-in head 301 and the second nose plug-in head 311 can be folded and deformed at any angle. The first nasal plug 30 and the second nasal plug 31 are both two-way air inlet structures with non-conducting middle parts.

It should be noted that, in the above embodiment, since the first nasal plug head 301 and the second nasal plug head 311 are connected, the first nasal plug head 301 and the second nasal plug head 311 are all soft rubber, so that the connection part of the first nasal plug head 301 and the second nasal plug head 311 can be folded and deformed at any angle, and thus the first nasal plug 30 and the second nasal plug 31 can be adjusted, so that the first nasal plug 30 and the second nasal plug 31 have better compliance when being attached to the face of an infant, the pressure on the face of the infant is reduced, the stability of the use of the nasal oxygen tube face is improved, and frequent replacement of patches is avoided. The connection between the first nose plug 301 and the second nose plug 311 may be an integral connection, a split connection, or a more specific connection manner such as socket connection, plug connection, and clamping connection.

In some embodiments, the securing device 4 further comprises a securing tube clip 41, a first side of the securing tube clip 41 being connected to the face patch 40, a second side of the securing tube clip 41 being connected to the nasal prong 3, the first side of the securing tube clip 41 being an opposite side of the second side of the securing tube clip 41. The fixing pipe clamp 41 is a frame structure formed by twisting and combining lines of a preset shape and section. In addition, the frame structure comprises a connecting channel 410, and the connecting channel 410 is tightly wrapped on the nose plug 3 at the penetrating position of the nose plug 3 and forms interference fit with the nose plug 3. The facial patch 40 includes a skin-compliant soft film 400 and a skin tape 401; the skin compliance film 400 is designed according to standard facial curves of infants at different ages, a first side of the skin compliance film 400 is provided with a skin adhesive tape 401, a second side of the skin compliance film 400 is connected with a first side of the fixed pipe clamp 41, and the first side of the skin compliance film 400 and the second side of the skin compliance film 400 are opposite sides. The skin-friendly flexible film 400 is made of thermoplastic elastic material, and a plurality of ventilation holes are formed in the skin-friendly flexible film 400. The second side of the skin-compliant flexible film 400 is integrally injection-molded with the first side of the fixed tube clamp 41 by an encapsulation process or by a two-shot molding process. The skin tape 401 is hydrocolloid; a double-sided adhesive is provided between the skin tape 401 and the skin-compliant flexible film 400 to connect the skin tape 401 and the skin-compliant flexible film 400. The frame structure is made of a hard solid thermoplastic elastomer material.

It should be noted that, since the fixing tube clip 41 is a frame structure, the frame structure is formed by twisting and combining lines with preset shapes and sections, so that the use of glue materials can be reduced, and the weight of the whole infant nasal oxygen cannula can be further reduced. In addition, since the frame structure includes the connecting channel 410, the connecting channel 410 wraps the nasal plug 3 at the passing position of the nasal plug 3, and forms interference fit with the nasal plug 3, so that the fixing pipe clamp 41 can be fixed at a certain position of the nasal plug 3 without falling off, and the normal performance of the nasal plug 3 is not affected. The length of the fixing tube clamp 41 can be only 6mm, and the fixing tube clamp is short enough to bear the weight of the nasal plug 3 and the face patch 40 without falling off. From the whole, the length of the 6mm fixing pipe clamp 41 can only occupy 10% -15% of the whole fixing device 4, so that the area of the fixing device 4 in fixed contact with the face is reduced, and the whole compliance is improved. In addition, the skin compliance soft film 400 is designed according to the standard facial curves of infants in different ages, so that the soft film can be well matched with the faces of infants. Because the skin-compliant flexible film 400 occupies 80% of the area of the underside of the eyelid and is made of a thermoplastic elastomer, such as TPE, it provides a large support surface and promotes stability in nasal oxygen cannula wear. Meanwhile, since the thermoplastic elastomer is impermeable to air, it is possible to choose to provide sufficient ventilation holes in the skin-friendly flexible film 400, and to reduce the thickness of the flexible film, thereby further increasing the compliance of the skin patch. In addition, the fixing tube clamp 41 and the skin compliance soft film 400 can be integrally formed by injection molding through an encapsulation process, so that the nasal plug 3 and the skin compliance soft film 400 can be integrated without falling off. In addition, since the skin tape 401 is a hydrocolloid that cannot be directly adhered to the thermoplastic elastomer, a double-sided adhesive may be optionally added between the skin-compliant flexible film 400 and the skin tape 401. The double-sided adhesive comprises, but is not limited to, acrylic adhesive, silica gel, organic adhesive and the like. In addition, due to the frame structure

The hard solid thermoplastic elastic material, such as hard TPU, is adopted, and the point of difference with the traditional PP pipe strap structure is that PP is easy to generate elastic deformation, and the original shape can not be rebounded after multiple disassembly and assembly.

It should be noted that, because the infant nasal oxygen cannula provided in the above embodiment includes the nasal catheter 1, the device connector 2, the nasal plug 3 and the fixing device 4, the nasal catheter 1 connects the nasal plug 3 and the device connector 2, the nasal plug 3 includes the first nasal plug 30 and the second nasal plug 31, the first nasal plug 30 and the second nasal plug 31 are connected in a foldable manner so that the joint can be folded and deformed at any angle, the fixing device 4 is connected with the nasal plug 3, the fixing device 4 includes the facial patch 40, and the facial patch 40 is attached to the skin of an infant to cover the face of the infant, so that the first nasal plug 30 and the second nasal plug 31 are attached to the face of the infant with better compliance, the pressure on the face of the infant is reduced, the stability of the use of the nasal oxygen cannula face is improved, and frequent replacement of the facial patch is avoided.

The foregoing is a description of the embodiments of the present utility model, and is not to be construed as limiting the utility model, since modifications in the detailed description and the application scope will become apparent to those skilled in the art upon consideration of the teaching of the embodiments of the present utility model.
