Description

Nasal oxygen cannula

Technical Field

The utility model relates to the field of medical supplies, in particular to a nasal oxygen tube.

Background

The nasal oxygen catheter is a medical supply that the daily oxygen uptake of present patient all will use, and present nasal oxygen catheter structure is complicated, and the bonding process link is many, and the risk of gas leakage and stifled pipe also corresponding increase adopts plastics injection moulding, and the shape is fixed, often can't hug closely patient face during the use, and present nasal oxygen catheter is buckled easily with oxygen catheter after being connected with oxygen catheter and is blockked up moreover, need hang oxygen catheter behind a side ear, very uncomfortable.

SUMMERY OF THE UTILITY MODEL

The utility model provides a nasal oxygen cannula, simple structure can hug closely patient's face, and is simple to use, uses moreover more comfortablely.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a nasal oxygen cannula, includes soft main part, one side middle part of soft main part be provided with into oxygen pipe, the one end of advancing oxygen pipe be provided with the picture peg hole, the upside of advancing oxygen pipe be provided with an at least oxygen pipe, the both ends of soft main part be the disk portion that has the edge uplift that makes progress, be close to be provided with the spacing lantern ring on the disk portion of picture peg hole.

Preferably, the other end of the oxygen inlet pipe is provided with a reinforcing convex rib extending to the circular sheet part.

Preferably, the soft main body, the oxygen inlet pipe, the limiting lantern ring and the reinforcing convex rib are made of soft PVC materials or silica gel materials through integral forming.

Preferably, the circular pieces at both ends of the soft main body are provided with through holes, and an elastic band is connected between the through holes at both ends.

Preferably, the back of the elastic band is coated with an anti-slip coating.

Preferably, the radial two sides of the through hole are symmetrically provided with transverse grooves.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the structure is novel, the appearance is beautiful, the soft material is adopted for manufacturing, and the contact with the face is more comfortable;

2. the oxygen tube is provided with a limiting lantern ring, so that the oxygen tube avoids the mouth of a person, the oxygen tube does not turn sharply to cause poor ventilation, and the oxygen tube does not need to be hung on ears;

3. the two ends of the soft main body are provided with the round sheets which are bulged upwards, so that the soft main body can be well attached to the cheek parts, the adhesive force is increased, and the soft main body is not easy to slide.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the utility model provides a nasal oxygen cannula, including soft main part 1, one side middle part of soft main part 1 be provided with into oxygen pipe 2, the one end of advancing oxygen pipe 2 be provided with cannula hole 7, the upside of advancing oxygen pipe 2 be provided with at least one play oxygen pipe 3, the both ends of soft main part 1 for having marginal upwarping disk portion 8, be close to be provided with spacing lantern ring 9 on the disk portion 8 of cannula hole 7.

In order to improve the overall strength of the nasal oxygen tube and prevent the nasal oxygen tube from breaking due to excessive bending, the other end of the oxygen inlet tube 2 is provided with a reinforcing convex rib 4 extending to the circular sheet part 8.

The soft main body 1, the oxygen inlet pipe 2, the limiting lantern ring 9 and the reinforcing convex rib 4 are made of soft PVC materials or silica gel materials which are commonly used by being integrally formed, and other known soft materials such as TPU and the like can be used in the actual production process.

In order to facilitate the installation of the elastic band 10, the circular plate parts 8 at the two ends of the soft main body 1 are provided with through holes 5, the elastic band 10 is connected between the through holes 5 at the two ends, and meanwhile, the back of the elastic band 10 is coated with an anti-slip coating, so that the sliding of the elastic band 10 can be effectively reduced.

The radial two sides of the through hole 5 are symmetrically provided with transverse grooves 6, the elastic band 10 is generally flat, and can penetrate through the transverse grooves 6 to be knotted when being connected, so that the end part of the elastic band 10 can be effectively prevented from rotating.

As an embodiment of the utility model, the upper side of the oxygen inlet pipe 2 is provided with two oxygen outlet pipes 3, when in use, the nasal oxygen pipe is fixed on the face of the patient by the elastic band 10, as shown in fig. 3, two connection modes are provided between the oxygen inlet pipe and the nasal oxygen pipe, the first mode is that a longer oxygen inlet pipe is directly inserted into the plug hole 7 and fixed by glue without being pulled out. The second is that the oxygen inlet pipe 2 is inserted into a ventilating pipe with the length of 20CM and fixed by glue, and then the long oxygen conveying pipe is connected through a hard plastic double-way head, so that the front part can be disinfected, and the back oxygen conveying pipe can be replaced by cheap non-silica gel materials at one time.
