Detailed Description
The attached drawings are specific embodiments of the invention. As shown in figures 1 to 6, the posterior nares blocking support comprises two developing vent pipes 1, the vent pipes 1 are made of rubber pipes, springs 7 are embedded in the rubber pipes, when in use, one vent pipe 1 is arranged in each of the two nares, the outer end of each vent pipe 1 is in a bell mouth shape, one groove 2 is respectively arranged at each of the two ends of each vent pipe 1 and one side of the nasal septum, the groove 2 on each vent pipe 1 and the axial lead of the vent pipe 1 are positioned in a plane to facilitate binding of fixing bands 5, a front and back direction drainage groove 3 is arranged in each vent pipe 1, the included angle between each groove 2 and each drainage groove 3 is 60-120 degrees, preferably 90 degrees when viewed from the cross section, because the two vent pipes 1 are simultaneously inserted into the two nares, if the grooves 2 and the drainage grooves 3 are placed in a coordinate system, the drainage grooves 3 of the two vent holes are both on a negative half axis of a Y axis, and the grooves 2 on the vent pipes 1 of the left, preferably on the negative half axis of the X-axis, the groove 2 on the vent tube 1 of the right nostril is a quadrant, but preferably on the positive half axis of the X-axis; the two ventilation tubes 1 can be fixed on the nose by fixing belts 5 through the grooves 2 on the two ventilation tubes 1 (the left nostril and the right nostril are for the patient, and the coordinate axes are from the perspective of the doctor). Two grooves 2 are located on the straight section of the vent pipe 1.
A plurality of through holes 4 are formed on the pipe wall of each breather pipe 1, and the shape of the through holes 4 is preferably diamond.
In order for the surgeon to grasp the depth of insertion of the ventilation tubes 1, a scale 6 is engraved on each ventilation tube 1.
In order to adapt to different nasal cavity lengths and newborn infants with different ages, the ventilation tube 1 is designed into six models, wherein the six models respectively have the following lengths: 5 cm, 5.5 cm, 6 cm, 6.5 cm, 7 cm and 7.5 cm.
The through hole 4 is used for draining secretion in the nasal cavity to enter the breather pipe 1, and the drainage groove 3 is used for draining the secretion entering the breather pipe 1, so that the secretion flows out conveniently, scabbing is avoided, and the breather pipe 1 is blocked.
The through-hole 4 is located on the side near the alar, i.e. on the side opposite to the drainage channel 3. 2-3 through holes are formed in the substrate.
In order to prevent the straight ventilation tube 1 from causing the nasal alar upwarp and causing the nasal alar deformation, the part of the ventilation tube connected with the bellmouth is bent downwards, namely, the ventilation tube is bent towards the opposite direction of the nasal alar.
When the fixing device is used, the two ventilating pipes 1 are respectively inserted into nostrils, then the fixing band 5 is inserted into the posterior nostril from the ventilating pipe 1 of the nostril at one side, and is led out from the ventilating pipe 1 of the nostril at the other side under the guidance of an endoscope, and then is pulled out, and the two ends of the fixing band 5 are knotted at the horn mouth.
Since the ventilation tube 1 itself can be developed, even if it falls off into the esophagus or airway, it can be displayed by X-ray inspection.
Along with child's age, nasal cavity length changes, at this moment, can change the breather pipe 1 of a little bigger model: firstly, the fixing belt 5 is unfastened, the ventilating pipe 1 on one side is firstly drawn out, then the proper ventilating pipe 1 is selected to go in and out the fixing belt 5 on the side and is inserted into the nostril, then the ventilating pipe 1 on the other side of the nostril is replaced in the same way, and the whole process can be finished only by local anesthesia.
Other technical features than those described in the specification are known to those skilled in the art.
