Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to an anti-loosening nasal catheter. Background Art

[0002] In modern medical practice, nasal cannula is a commonly used non-invasive respiratory assistance device, especially when patients need supplemental oxygen or continuous positive airway pressure. The traditional nasal cannula design includes an air delivery tube and a nasal cannula tip, which is inserted into the patient's nostrils to provide respiratory support.

[0003] However, existing nasal cannulas have some shortcomings and limitations. First, due to the lack of an effective fixing mechanism, traditional nasal cannulas are prone to displacement or fall off during use, resulting in unstable treatment effects. Especially when the patient moves, talks, or changes expression, the nasal cannula tip can easily slip out of the nasal cavity, affecting the continuity of respiratory support. Secondly, traditional nasal cannulas do not take into account the differences in facial structure and cannot adapt well to the shape and size of the noses of different patients, causing discomfort and even skin damage. In addition, there are also problems with the fixation of the airway. Common straps or adhesive tape fixation methods either do not have sufficient fixing strength or cause skin allergies or damage after long-term use.

[0004] In view of the above deficiencies in the prior art, there is an urgent need in the art for an improved anti-loosening nasal cannula that can effectively solve the stability problem of the nasal cannula during use and improve the comfort and safety of patients. Utility Model Content

Specific embodiment one:

[0028] See also Figure 1-3As shown, the utility model is a kind of anti-loosening nasal catheter, including an air delivery tube 1, a nose patch holder 2 and a nasal tube air head 3. The nose patch holder 2 includes a nose patch 21 and a clamping plate 22. The clamping plate 22 includes an arched portion 221 located in the middle. A straight portion 222 is fixedly connected to both ends of the arched portion 221. The middle part of the upper surface of the nose patch 21 is adhered to the inner arc surface of the arched portion 221 as a whole. A first rectangular vertical plate 223 is fixed to the top of the outer arc surface of the arched portion 221. A first circular through hole 224 is provided on the first rectangular vertical plate 223. A pair of second rectangular vertical plates 225 are symmetrically fixed on both sides of the outer arc surface of the arched portion 221 on the first rectangular vertical plate 223. A second circular through hole 226 is provided on each of the two second rectangular vertical plates 225, and the second circular through hole 226 points obliquely upward to the first circular through hole 224. The design of the nose patch 21 and the clamping plate 22 can adapt to the facial structures of different users and provide personalized fit and comfort.

[0029] A trachea clamping groove 227 for clamping the air tube 1 is fixed on the upper surface of each of the two straight portions 222. The end of the air tube 1 passes through the first second round hole 226, the first round hole 224, and the second second round hole 226 in sequence and is connected to the nasal tube air head 3. The portion of the air tube 1 located above the straight portion 222 is pressed into the trachea clamping groove 227 and fixed. The air tube 1 is staggered in the middle of the clamping plate 22, and the two ends are clamped and positioned respectively, which effectively ensures that the air tube 1 does not move on the nose patch clamp 2.

[0030] The nose patch 21 is a T-shaped structure as a whole. The part where the nose patch 21 is combined with the arch 221 cooperates with the bridge of the nose. The two parts of the nose patch 21 symmetrical to the arch 221 are spread to both sides of the face, and the other part is extended upward along the bridge of the nose toward the center of the eyebrows and pasted and fixed. The nose patch 21 is pasted on the nose stably to form a stable positioning support for the clamping plate 22 thereon, effectively ensuring that the position of the nose patch holder 2 on the nose is fixed, and the close-range positioning ensures the stability of the connection of the nose tube air head 3.

[0031] The nasal tube air head 3 includes a connecting tube end 31 connected to the end of the air delivery tube 1. The end of the connecting tube end 31 is provided with a spherical air bag 32 connected as one body. A plurality of vent holes 33 are provided on the surface of the spherical air bag 32. The outer wall of the connecting tube end 31 is provided with a circular ring limit ring 34 connected as one body. The outer wall of the circular ring limit ring 34 is provided with an auxiliary positioning belt 35 connected as one body.

[0032] When the nasal tube air tip 3 is in use, the spherical air bag 32 is inserted into the nasal cavity, the bent auxiliary positioning belt 35 is attached to the side of the nose, and then the nose patch 21 is used to fix it, effectively ensuring that the nasal tube air tip 3 slides out of the nasal cavity.

[0033] In order to further fix the air tube 1, a number of fixing tapes 4 are also provided. Both the nose patch 21 and the fixing tape 4 use high-viscosity medical tape to ensure good adhesion and air permeability. Before use, a protective film is attached to the adhesive side of the nose patch 21 and the fixing tape 4. Two third round through holes 41 are provided on the fixing tape 4. The air tube 1 continuously passes through the two third round through holes 41 on the same fixing tape 4. The fixing tape 4 and the air tube 1 increase the friction with the surface of the air tube 1 in a staggered manner, which is beneficial to fix the position of the air tube.
