Background

The oropharyngeal airway is a non-tracheal catheter type airway, has the characteristics of simple operation and easy mastering, and is medical equipment capable of rapidly opening the trachea within a few seconds without special instruments. Oropharynx breather pipe mainly includes body and edge of a wing, and the inside of body is the air flue, and the body includes the good pharynx bent part of bite-block part. When in use, a proper catheter is selected to assist a patient to take a flat lying position and lean the head backward so that the mouth, the pharynx and the larynx form a straight line; then the pharyngeal bending part is directly placed close to the hard palate, and the ideal contraposition of the nasopharyngeal airway after the nasopharynx airway is placed is as follows: after insertion from the patient's nasal cavity into the pharyngeal cavity, the pharyngeal end is located 0.5cm outside the glottis. The pharynx rear wall can be supported by the alignment, so that the upper respiratory tract obstruction is relieved, the airway is kept smooth, and the pharynx bending part does not reach the root of the tongue often, so that the function of opening the trachea cannot be achieved; in addition, because the oropharyngeal airway needs certain hardness, when in use, the oropharyngeal airway is easy to damage the throat part, and further the throat bleeding is caused.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at overcoming the defect among the prior art, provide improvement type straight tube oropharynx breather pipe, can avoid the throat position damage, convenient operation uses comfortablely.

The utility model discloses an improvement type straight tube oropharynx breather pipe, including straight pipy hose body, be provided with the protruding muscle of bar along length direction in the hose body, the protruding muscle of bar causes the jam of hose body inner chamber when being used for preventing the hose body crooked.

Furthermore, the transverse section of the flexible pipe body is in a waist-shaped hole shape, the strip-shaped convex ribs are fixed on the inner top wall or the inner bottom wall of the flexible pipe body, and the strip-shaped convex ribs are multiple and are distributed in parallel along the transverse direction.

Further, a plurality of vent holes are formed in the flexible pipe body close to the front end, and are distributed along the circumferential direction of the flexible pipe body.

The flexible pipe comprises a flexible pipe body, and is characterized by further comprising a hard inner supporting sleeve and a tooth positioning ring, wherein the hard inner supporting sleeve is sleeved at the front end of the flexible pipe body in a shape fitting mode, and the tooth positioning ring is a C-shaped split ring and is fixedly sleeved at the front end of the flexible pipe body in an interference fit mode.

Further, the tooth positioning ring is L-shaped along the radial section.

Furthermore, the tooth positioning ring comprises a front tooth positioning ring and a rear tooth positioning ring, and a tooth limiting groove is formed between the front tooth positioning ring and the rear tooth positioning ring.

Further, the flexible pipe body is a transparent or semitransparent pipe body.

The utility model has the advantages that: the utility model discloses an improvement type straight tube oropharynx breather pipe through setting up oropharynx breather pipe into the software structure, avoids hard material to the damage at throat position to the hose body more can be fit for different patients' throat radian, improves the comfort level of using, and set up the protruding muscle of bar that causes hose body inner chamber to block up when being used for preventing that the hose body is crooked in the hose body, guarantees safe in utilizationly.

Drawings

The invention will be further described with reference to the following figures and examples:

fig. 1 is a schematic structural view of the present invention;

fig. 2 is a sectional view a-a of fig. 1.

Detailed Description

Fig. 1 is a schematic structural view of the present invention, fig. 2 is a sectional view taken along a line a-a of fig. 1, and as shown in the drawing, the improved straight tube oropharyngeal airway in the present embodiment includes a straight tube body 1, a bar-shaped rib 2 is disposed in the tube body 1 along a length direction, and the bar-shaped rib 2 is used for preventing an inner cavity of the tube body 1 from being blocked when the tube body 1 is bent; the flexible pipe body 1 is a transparent or semitransparent pipe body; hose body 1 is prepared by software silica gel or rubber materials, through setting up oropharynx breather pipe into the software structure, avoids hard material to the damage at throat position to hose body 1 more can be fit for different patients' throat radian, improves the comfort level of using, and sets up the protruding muscle 2 of bar that causes 1 inner chamber of hose body to block up when being used for preventing 1 crooked flexible hose body in hose body 1, guarantees safe in utilizationly.

In this embodiment, the transverse section of the flexible pipe body 1 is a waist-shaped hole, the strip-shaped ribs 2 are fixed on the inner top wall or the inner bottom wall of the flexible pipe body 1, and the strip-shaped ribs 2 are a plurality of ribs and are distributed in parallel along the transverse direction; the inner top wall and the inner bottom wall of the flexible pipe body 1 respectively represent an upper plane wall and a lower plane wall in the flexible pipe body 1, the width direction of the flexible pipe body 1 is transversely represented, the height of the strip-shaped convex rib 2 is one third to one half of the height of the inner cavity of the flexible pipe body 1, the strip-shaped convex rib 2 with the height is favorable for guaranteeing the flexibility of the flexible pipe, and the strip-shaped convex rib 2 and the flexible pipe body 1 are integrally formed.
