Abstract

The utility model relates to the technical field of a medical auxiliary ventilating tool, in particular to a weakly stimulating biomimetic oropharyngeal ventilating passage. The ventilating passage comprises an oropharyngeal ventilating passage body, wherein the oropharyngeal ventilating passage body comprises a ventilating passage pipe body, an outer ventilating passage opening is formed in the outer end of the ventilating passage pipe body, and an inner ventilating passage opening is formed in the inner end of the ventilating passage pipe body; the ventilating passage pipe body is in the shape that the outer ventilating passage opening is circular or oval and a flat oval structure with a concave middle part is gradually formed inwards, and the ventilating passage pipe body consists of an arc concave pipe body tongue surface and a pipe body jaw surface; a concave tongue root support is arranged at the middle concave part of the surface of the pipe body tongue surface; a separating baffle is sleeved with the upper part of the ventilating passage pipe body, and a fixing strip is arranged on the separating baffle. By the adoption of the passage, the latter half part of the tongue surface and the tongue root part of the ventilating passage pipe body are designed into concave shapes, so that compared with the traditional oropharyngeal ventilating passage, a patient is easier to tolerate, the unsuitability of the patient can be reduced, and the imbedding effect can be improved.

Description

The weak bionic-type oropharyngeal airway that stimulates

Technical field

This utility model relates to medical assisted ventilation technical field of tools, particularly a kind of weak bionic-type oropharyngeal airway that stimulates.

Background technology

Oropharyngeal airway is a kind of assisted ventilation apparatus, and it can direct oral cavity be incorporated into pharyngeally, utilizes the support of airway body that the root of the tongue is passed forward, expands pharyngeal cavity, improves the airway obstruction causing because of glossoptosis, oropharynx are narrow or secretions etc., improves ventilation; People's the root of the tongue is distributed with abundant sensory nerve ending, therefore stimulates the root of the tongue discomfort that can cause nausea.And the sensory nerve of root of the tongue mid portion distributes than the more crypto set on root of the tongue both sides, so stimulate root of the tongue mid portion stronger than the reaction that stimulates the both sides of the root of the tongue to cause.

Traditional ventilation instrument, the first half of its airway body is pressed in the middle of the root of the tongue, and the distribution of root of the tongue mid portion sensory nerve is abundant, strong to irritant reaction, so insert traditional oropharyngeal airway, patient is difficult for tolerance.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple in structure, weak stimulation bionic-type oropharyngeal airway reasonable in design, easy to use, it adopts the lingual surface latter half of airway body and root of the tongue part to adopt spill design, insert after airway, utilize the both sides of airway body, from the both sides of the root of the tongue, the root of the tongue is passed forward, expand pharyngeal cavity, improve ventilation; And the mid portion of the root of the tongue is arranged in the depression of airway body, therefore airway body is little to the stimulation of root of the tongue mid portion, with respect to traditional oropharyngeal airway, patient more easily tolerates, and can reduce the inadaptable of patient and improve and insert effect.

For achieving the above object, the technical solution adopted in the utility model is:

The weak bionic-type oropharyngeal airway that stimulates described in the utility model, it comprises oropharyngeal airway body, and described oropharyngeal airway body comprises an airway body, and the external end of described airway tube is airway collar extension, and the inner of this airway body is breather internal orifice; Being shaped as of described airway body, the rounded or elliptical shape of its airway collar extension, then inwardly divides a word with a hyphen at the end of a line gradually as umbilicate flat ellipse structure, and this airway body is made up of body lingual surface and the body jaw face of arc concavity; The part of described body lingual surface surface medial recess arranges a spill root of the tongue holder; The sheathed separation baffles in described airway body top, arranges a fixing band in this separation baffles, the two ends of this fixing band is provided with the fixing band thread gluing matching.

Further, in the body jaw face of described airway body, a support chip is set.

Adopt after said structure, this utility model beneficial effect is: the weak bionic-type oropharyngeal airway that stimulates described in the utility model, it adopts the lingual surface latter half of airway body and root of the tongue part to adopt spill design, insert after airway, utilize the both sides of airway body, from the both sides of the root of the tongue, the root of the tongue is passed forward, expanded pharyngeal cavity, improve ventilation; And the mid portion of the root of the tongue is arranged in the depression of airway body, therefore airway body is little to the stimulation of root of the tongue mid portion, with respect to traditional oropharyngeal airway, patient more easily tolerates, and can reduce the inadaptable of patient and improve and insert effect.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described.

As shown in Figure 1, the weak bionic-type oropharyngeal airway that stimulates described in the utility model, it comprises oropharyngeal airway body, described oropharyngeal airway body comprises an airway body 4, described airway body 4 outer ends are airway collar extension 2, and the inner of this airway body 4 is breather internal orifice 6; Being shaped as of described airway body 4, the rounded or elliptical shape of its airway collar extension 2, then inwardly divides a word with a hyphen at the end of a line gradually as umbilicate flat ellipse structure, and this airway body 4 is made up of body lingual surface 7 and the body jaw face 8 of arc concavity; The part of described body lingual surface 7 surperficial medial recess arranges a spill root of the tongue holder 5; The sheathed separation baffles 3 in described airway body 4 tops, arranges a fixing band 1 in this separation baffles 3, the two ends of this fixing band 1 is provided with the fixing band thread gluing 9 matching.

The interior support chip that arranges of body jaw face 8 of described airway body 4.

In this utility model, airway body 4 adopts pliable and tough macromolecule material, and soft flexible, tissue injury is little; Its body jaw face 8 can a built-in support chip, with in case airway tube body give a discount; Spill root of the tongue holder 5 adopts spill design, is because sensory nerve distributes abundantly, strong to irritant reaction, and that root of the tongue both sides sensory nerve distributes is relatively less in the middle of the root of the tongue, a little less than irritant reaction, therefore adopts stimulation that airway holds up the root of the tongue more much smaller than traditional.

The weak bionic-type oropharyngeal airway that stimulates described in the utility model, it adopts the lingual surface latter half of airway body and root of the tongue part to adopt spill design, inserts after airway, utilize the both sides of airway body, from the both sides of the root of the tongue, the root of the tongue is passed forward, expanded pharyngeal cavity, improve ventilation; And the mid portion of the root of the tongue is arranged in the depression of airway body, therefore airway body is little to the stimulation of root of the tongue mid portion, with respect to traditional oropharyngeal airway, patient more easily tolerates, and can reduce the inadaptable of patient and improve and insert effect.

The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in this utility model patent claim therefore all changes or modifies, and is included in this utility model patent claim.
