Abstract
The utility model relates to a nasal oxygen cannula for oxygen therapy. The nasal oxygen cannula for oxygen therapy comprises an oxygen inlet pipe and a nose head, wherein the nose head is arranged at one end of the oxygen inlet pipe and is communicated with the oxygen inlet pipe; two nose plugs communicated with the nose head are arranged on the nose head; the distance between the two nose plugs is the same as that between two nasal apertures of the human body; the outer diameter of one end, connected with the nose head, of each nose plug is smaller than that of the other end different from the nose head; the nose plugs are horn-shaped. According to the nasal oxygen cannula for oxygen therapy disclosed by the utility model, compared with the prior art, the shapes of the nose plugs are arranged to be in the shape of horns similar to the shapes of inner cavities of the nasal apertures, so that the falling of the nose plugs caused by incorrect inserting manner is prevented, and the treatment stability of a patient is improved; meanwhile, a 150-degree arc-shaped chamfering is formed on the end periphery of each horn-shaped nose plug, so that the damage to nasal mucosa when the nose plugs are inserted is prevented, and the arc-shaped chamfering plays a role of guiding.
Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of nasal oxygen cannula for transferring oxygen.
Background technology
Oxygen therapy is one of important step of rescue patient clinically, general carry out the oxygen therapy to patient with oxygen therapy pipeline, one end connection oxygen source of oxygen therapy pipeline, the other end by nasal obstruction for patient, after oxygen source is opened, oxygen can enter patient's nasal cavity by oxygen therapy pipeline.At present, the nasal oxygen cannula for transferring oxygen that most hospitals are used, by amphirhinal intubate, walk around arm that patient's two ears and lower jaw use, regulate adjusting lock, four-way connection, the house steward of a length of tube and be formed by connecting with the joint that source of oxygen is joined.While using this oxygen feeding tube to cure by oxygen therapy to patient, amphirhinal intubate is directly inserted to patient nostril, if insertion dynamics or the angle of amphirhinal intubate are incorrect, easily cause nostril intubate to come off, cause patient to cure by oxygen therapy interruption, also can damage patient's bronchia mucosal simultaneously, to patient's secondary injury that arrives.
Utility model content
This utility model object is to provide a kind of nasal oxygen cannula for transferring oxygen, incorrect to solve insertion dynamics or the angle of amphirhinal intubate of nasal oxygen tube of the prior art, easily causes nostril intubate to come off, and causes patient to cure by oxygen therapy the technical matters of interruption.
The technical solution of the utility model is achieved in that
A kind of nasal oxygen cannula for transferring oxygen, the nose that comprises oxygen feeding tube and be arranged on oxygen feeding tube one end and be communicated with oxygen feeding tube, on described nose, be provided with two nasal obstructions that are communicated with nose, distance between distance and human body two nostrils between described two nasal obstructions is consistent, the external diameter that described nasal obstruction connects nose one end is less than the external diameter that differs from nose one end, and described nasal obstruction is horn-like.
Preferably, the described nasal obstruction arc pipe of nostril wall that is set to recline.
Preferably, the periphery, end of described horn-like nasal obstruction is set to the arc angling of 150 °.
Preferably, the two ends of described nose are connected with oxygen feeding tube by union joint respectively, and the inner surface of described union joint is the conical surface.
Preferably, a side that differs from nasal obstruction on described nose is provided with handle, and described handle and nose are adopt injection moulding or soak molded integrative-structure.
Compared with prior art, this utility model has following beneficial effect:
1, nasal oxygen cannula for transferring oxygen of the present utility model, arranges the horn-like of similar nostril cavity shape by the profile of nasal obstruction, has avoided incorrect inserted mode to cause nasal obstruction to come off, and promotes the stability of patient treatment;
2, the periphery, end of the horn-like nasal obstruction of nasal oxygen cannula for transferring oxygen of the present utility model is set to the arc angling of 150 °, prevents when nasal obstruction from inserting bronchia mucosal to cause damage, and meanwhile, this arc angling has guide effect.
Brief description of the drawings
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is nose structural representation of the present utility model;
Fig. 2 is nasal oxygen cannula for transferring oxygen structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of this utility model protection.
Please refer to accompanying drawing 1-2, a kind of nasal oxygen cannula for transferring oxygen, the nose 2 that comprises oxygen feeding tube 1 and be arranged on oxygen feeding tube 1 one end and be communicated with oxygen feeding tube 1, on described nose 2, be provided with two nasal obstructions 3 that are communicated with nose 2, distance between described two nasal obstructions 3 and the distance between human body two nostrils are consistent, the external diameter that described nasal obstruction 3 connects nose 2 one end is less than the external diameter that differs from nose 2 one end, described nasal obstruction 3 is horn-like, trumpet-shaped nasal obstruction 3 can ensure that the nose end of filling in better contacts with human body nasal cavity, prevent from coming off, simultaneously, the external diameter of nose 3 ends is larger, oxygen therapy amount relatively can be excessive, and 3 oxygen are out diffused in nasal cavity uniformly from having a stuffy nose, ensure the more comfortable use of patient, described nasal obstruction 3 be set to the to recline arc pipe of nostril wall, profile and the nasal cavity structure of arc pipe are similar, have further promoted the practicality of nasal oxygen cannula for transferring oxygen, described trumpet-shaped nasal obstruction 3 peripheries, end are set to the arc angling 4 of 150 °, arc angling smooth surface and have guidance quality, the two ends of described nose 2 are connected with oxygen feeding tube 1 by union joint 5 respectively, and the inner surface of described union joint 5 is the conical surface, a side that differs from nasal obstruction 3 on described nose 2 is provided with handle 6, and described handle 6 is stuck in patient's nose below, avoids the nasal obstruction 3 that is fixed on patient's nasal cavity not come off, and plays fixation, and described handle 6 is adopt injection moulding or soak molded integrative-structure with nose 2.
To sum up structure of the present utility model is known, and the profile of nasal obstruction is arranged the horn-like of similar nostril cavity shape by nasal oxygen cannula for transferring oxygen of the present utility model, has avoided incorrect inserted mode to cause nasal obstruction to come off, and promotes the stability of patient treatment; Meanwhile, the periphery, end of horn-like nasal obstruction is set to the arc angling of 150 °, prevent when nasal obstruction from inserting bronchia mucosal to cause damage, and this arc angling has guide effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
