Detailed Description

The present application is described in further detail below in conjunction with figures 1-3.

The embodiments of the present application disclose atraumatic nasopharyngeal airway tubes. Referring to fig. 1, the atraumatic nasopharyngeal airway tube includes a tube body 1. The pipe body 1 is a hose and is made of soft silica gel or plastic materials, one end opening 2 of the pipe body 1 is arranged, and the opening 2 of the pipe body 1 is a horn mouth. When it is desired to supply air to the nasopharyngeal airway tube, air is conveniently supplied from the side of the larger flare opening 2.

The one end that opening 2 was kept away from to body 1 is equipped with insert 3, and the tip circular arc of insert 3 sets up and one side is equipped with through-hole 4, and the seting up of through-hole 4 does not influence body 1 normally with gaseous carrying to in the human body. Meanwhile, the insertion part 3 with the arc-shaped end part is more attached to the inner structure of the nasal cavity, the contact area between the insertion part and the insertion part is increased in the insertion process, the pressure of the tube body 1 on the nasal cavity is reduced, and the damage to nasal cavity tissues is reduced.

One end of the pipe body 1, which is close to the opening 2, is movably connected with a shielding part 5, and the shielding part 5 is connected to the pipe body 1 through a flexible belt. The shape of the shielding part 5 is matched with the opening 2, so that the shielding part 5 can be used for controlling the blocking of the opening 2 according to actual needs, and the opening 2 is communicated with or closed to the outside atmosphere. The periphery of the shielding part 5 is fixed with a bulge 6, and the bulge 6 is annular block-shaped. After the shielding part 5 blocks the opening 2 of the pipe body 1, the bulge 6 can provide a contact site for personnel, so that the personnel can conveniently apply force to the shielding part 5 and open the opening 2 of the pipe body 1.

Referring to fig. 2, an inner support assembly 7 is fixedly coupled to an inner wall of the pipe body 1, and the inner support assembly 7 includes an inner support portion 71 and a connection member 72. The inner support portion 71 is strip-shaped and flexible, and the length of the inner support portion 71 is parallel to the longitudinal direction of the pipe body 1. The inner supporting parts 71 are arranged at intervals by taking the middle point of the inner diameter of the pipe body 1 as the center of a circle, and the supporting parts are connected together through connecting pieces 72, wherein the connecting pieces 72 are annular and have toughness. Because the nasopharyngeal breather pipe is hose and cavity setting, the nasopharyngeal breather pipe lacks the internal stay when receiving external force, takes place to buckle easily. The inner support assembly 7 can support the pipe body 1 to provide stress points for a person so as to conveniently extend the nasopharynx vent pipe into the nasal cavity.

The inner support assembly 7 is provided with a plurality of groups along the length direction of the pipe body 1. The multi-group internal stay assembly 7 can provide multi-point support for a person at the nasopharynx breather pipe, so that the pipe body 1 can be conveniently and continuously stretched into the nasal cavity.

Referring to fig. 3, the insertion portion 3 is detachably disposed on the pipe body 1, and an extension portion 8 is disposed at an end of the insertion portion 3 away from the through hole 4, and an outer diameter of the extension portion 8 is smaller than an outer diameter of the pipe body 1. The circumference side of extension 8 is provided with external screw thread 9, is equipped with internal screw thread 10 on the inside wall of body 1 one end of keeping away from opening 2, under the cooperation of external screw thread 9 and internal screw thread 10, realizes that insert 3 spiro union is on body 1 to the convenience is dismantled insert 3 and is washd and change.

The implementation principle of the atraumatic nasopharyngeal airway tube in the embodiment of the application is as follows: when the nasopharynx breather pipe is needed to be used, the insertion part 3 of the pipe body 1 is firstly extended into the nasal cavity, and then an external force is applied to the pipe body 1 by one hand of a person so that the pipe body 1 is continuously extended into the nasal cavity. When the pipe body 1 receives external force, the inner support component 7 plays a role in supporting the inner wall of the pipe body 1, and the situation that the pipe body 1 is stressed and bent is reduced. When the tube body 1 extends to a sufficient length, air is input into the opening 2 of the tube body 1, and enters the nasal cavity along the tube body 1 to realize air supply.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
