Abstract
The utility model discloses a kind of nasal mucus that prevents and flow into the nasal obstruction oxygen catheter of having a stuffy nose in head, effectively avoid nasal mucus and pollute, block oxygen catheter.Nasal obstruction oxygen catheter, comprises oxygen catheter, is connected to the oxygen-supply head on oxygen catheter and is arranged on the nasal obstruction head on oxygen-supply head; The end that described nasal obstruction head inserts nasal cavity is spherical cambered surface closing end, and described spherical cambered surface closing end is made up of the limb of at least three arcs.The spherical cambered surface closing end formed by arc limb, when not passing into oxygen, each limb is closed, and nasal mucus can be stoped to enter this nasal oxygen tube; When passing into oxygen, each limb can outwards launch to form inclination cambered surface, and nasal mucus can not enter in nasal obstruction head under the guide functions of limb curved surfaces, avoids this oxygen catheter to be polluted by nasal mucus, blocks.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of nasal obstruction oxygen catheter.
Background technology
Oxygen therapy is one of important step of rescue patient clinically, general use oxygen therapy pipeline comes to patient's oxygen therapy, and oxygen therapy pipeline one end is communicated with oxygen supply equipment, and the other end passes through nasal obstruction for patient, after oxygen supply equipment is opened, oxygen can enter the nasal cavity of patient by oxygen therapy pipeline.Current oxygen catheter is substantially all adopt transparent plastics material, oxygen therapy pipeline is circular hole, patient is inserted in nasal cavity the nasal obstruction head on oxygen-supply head when using, because nasal obstruction head upper end is circular hole opening, the nasal mucus that in respiratory, patient produces easily flows into pollution in nasal obstruction head, blocking oxygen therapy pipeline, causes for problems such as hypoxgia.
Utility model content
Problem to be solved in the utility model there is provided a kind of nasal mucus that prevents and flows into the nasal obstruction oxygen catheter of having a stuffy nose in head.
This utility model solves the technical scheme that its technical problem adopts: nasal obstruction oxygen catheter, comprises oxygen catheter, is connected to the oxygen-supply head on oxygen catheter and is arranged on the nasal obstruction head on oxygen-supply head; The end that described nasal obstruction head inserts nasal cavity is spherical cambered surface closing end, and described spherical cambered surface closing end is made up of the limb of at least three arcs.
Further, the afterbody of described nasal obstruction head is provided with the projection of annular.
Further, the shape and structure of described limb is identical.
Further, the tip of described limb is provided with fillet.
Further, described nasal obstruction head is two, and is symmetricly set on oxygen-supply head.
Further, the sidewall of above-mentioned two nasal obstruction heads is respectively equipped with a fixed bar, and described fixed bar is between two nasal obstruction heads.
Further, described fixed bar is made up of the plastics of softness.
The beneficial effects of the utility model are: the spherical cambered surface closing end consisted of arc limb, and when not passing into oxygen, each limb is closed, and nasal mucus can be stoped to enter this oxygen catheter; When passing into oxygen, each limb can outwards launch to form inclination cambered surface, and nasal mucus can not enter in nasal obstruction head under the guide functions of limb curved surfaces, avoids this oxygen catheter to be blocked by nasal mucus.The projection of annular can play fixation after nasal obstruction head enters nostril.Muscle in twinge nostril when fillet can prevent limb from launching.Fixed bar can be fixed on nasal septum after nasal obstruction screw plug enters nostril, and fixed effect is fine; Fixed bar is made up of the plastics of softness, is easy to fill in nostril and the immoderation caused to user after entering nostril is very little.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, nasal obstruction oxygen catheter, comprises oxygen catheter 1, is connected to the oxygen-supply head 2 on oxygen catheter 1 and is arranged on nasal obstruction on oxygen-supply head 23; Described nasal obstruction 3 end of inserting nasal cavity are spherical cambered surface closing end, and described spherical cambered surface closing end is made up of the limb 31 of at least three arcs.Wherein, limb 31 is overlooked in fan-shaped (fan-shaped radian is less than π), the shape and structure of limb 31 is all generally identical, and certain limb 31 also can be vary in size (size refers generally to the size that limb 31 overlooks fan-shaped radian herein), as shown in Fig. 2,4,6; The side of adjacent two limbs 31 fits tightly, and forms a closed spherical cambered surface; This oxygen catheter entirety generally adopts plastic production, particularly the plastics of quality softness, and when passing into oxygen, limb 31 outwards can launch to form the arc shelter wall of inclination along with air-flow; When nasal mucus is dirty, the curved surfaces of limb 31 plays the effect of water conservancy diversion and stop, avoids nasal mucus to flow in nasal obstruction 3 polluting, blocks this oxygen catheter.
In order to make this oxygen catheter well be fixed on nose, be provided with the projection 32 of annular at the afterbody of nasal obstruction 3, as shown in Fig. 1,2,5,6; Because the overall general employing of oxygen catheter is that flexible material makes, during use, the projection 32 of annular can not cause sense of discomfort to user.
Concrete, each limb 31 shape and structure is all identical, as shown in Fig. 2,4,6.
It can also be seen that from Fig. 2 and Fig. 6, the tip of described limb 31 is provided with fillet 311, and fillet 311 can be avoided when limb 31 launches twinge or stab user.
Concrete, described nasal obstruction 3 is two, and nasal obstruction 3 is symmetricly set on oxygen-supply head 2, as shown in Fig. 1,2,5,6.
As preferred scheme of the present utility model, in this oxygen catheter two nasal obstructions 3 sidewall on be respectively equipped with a fixed bar 33, described fixed bar 33 between two nasal obstructions 3, as shown in Fig. 1,2,5,6; User loads latter two fixed bar 33 of this oxygen catheter and just in time can be fixed on nasal septum (valves between two nostrils), and fixed effect is very good; Concrete, fixed bar 33 is made up of the plastics of softness, and fixed bar 33 surface is very smooth and its end generally adopts smooth round-corner transition, and user has just started to feel slightly uncomfortable, uses sense of discomfort a little while to disappear.
