Abstract

The utility model relates to an oropharynx ventilating tube used in cardiopulmonary resuscitation, which is in a structure of am arc-shaped tube. The upper part of the ventilating tube is provided with a wing flange which is larger than the external diameter of the tube. The section of the ventilating tube at the upper part of the wing flange is a round tube, and the section of the ventilating tube at the lower part of the wing flange is an elliptical tube. The protruding wing flange is positioned between lips and teeth of a patient so as to ensure that a lower opening of the ventilating tube is positioned at a proper position in laryngopharynx. The upper opening of the ventilating tube which is a huffing opening is positioned on the external side of a buccal cavity. The utility model can also be used for ventilating air ducts of unconscious patients who has complete or partial obstruction of upper respiratory ducts and/or need mouth props after an anesthesia induction. The utility model is also helpful to absorb phlegm accumulated at the pharyngeal portion of a patient. Meanwhile, the utility model has the function of ventlating air ducts for patients who snores and have the sleep apnea syndrome. The utility model which has the advantage of simple structure is convenient for being operated by medical care personnel. Under the condition of an emergent rescue, the utility model can rapidly establish effective and artificial respiration. Therefore, the utility model can effectively reduce pain of patients and improve survival rate of patients. The utility model is suitable for clinical expansion.

Description

A kind of oropharyngeal airway

Technical field

This utility model belongs to medical apparatus and instruments, is specially a kind of oropharyngeal airway that uses in cardio-pulmonary resuscitation.

Background technology

When medical clinical rescue sudden cardiac arrest, setting up timely and effectively, the artificial respiration is the key of cardio-pulmonary resuscitation.The at present clinical tracheal intubation of implementing in cardio-pulmonary resuscitation is set up the artificial respiration, and this is the definite effective method that keeps respiratory smooth and be convenient to breathe management.But the tracheal intubation specification requirement is higher, and needs complete apparatus and professional just can finish, so be difficult to carry out under urgent rescue situation, also is unfavorable for promoting.

Summary of the invention

The purpose of this utility model is to provide a kind of can in time set up the artificial respiration, and makes the patient keep a kind of oropharyngeal airway of respiratory smooth.

For achieving the above object, described oropharyngeal airway adopts a curved pipe structure, is provided with the edge of a wing greater than this breather external diameter on this breather top, and the breather on top, the edge of a wing partly is a pipe, and the breather of bottom, the edge of a wing partly is an elliptical tube.

Adopt the oropharyngeal airway of said structure, curved pipe and palate shape are matched, select the oropharyngeal airway of suitable size, put it into by in the oral cavity of rescue patient, make the outstanding edge of a wing between patient's lips and teeth, be positioned at the suitable position of bottleneck throat to guarantee the breather end opening; Breather is suitable for reading to be that inflatable mouth is positioned at outside the oral cavity, is convenient to be connected with air bag or respirator when save operation.

The technological progress that this utility model is obtained: 1. owing to be provided with the edge of a wing greater than the breather external diameter on top of the present utility model, so guaranteed that at first the breather end opening can be positioned at by the suitable position of rescue patient bottleneck throat in operation, so that air or oxygen is directly blown to patient's bottleneck throat, its outstanding edge of a wing is clamped in and can also be played the effect of breather at the oral cavity internal fixation that make between the rescue patient lips and teeth effectively simultaneously.2. because this utility model is simple in structure, be convenient to medical personnel operation, under urgent rescue situation, can setting up effective artificial respiration fast, thus can effectively reduce the patient misery, improve patient's rate of surviving.

Description of drawings

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

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

Fig. 3 is the B-B cross-sectional schematic of Fig. 1.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, oropharyngeal airway described in the utility model adopts the curved pipe structure, and the radian of this curved pipe and back bow are adapted, one edge of a wing 1 greater than this breather external diameter is set on this breather top, the breather on 1 top, the edge of a wing partly is a pipe, and the breather of 1 bottom, the edge of a wing partly is an elliptical tube.Adopt the oropharyngeal airway of said structure, curved pipe and palate shape are matched.According to clinical needs, this utility model can be made into some kinds of models such as large, medium and small or size.This utility model can adopt rigid plastics to make, so that there is high compression strength at the bite-block position under the edge of a wing, or reinforce in the pipe at bite-block position with the harder plastic tube of anti-tooth biting force, to guarantee the effectively unimpeded of when the patient to unconsciousness implements rescue operation oropharyngeal airway.

This utility model is when the cardio-pulmonary resuscitation save operation, at first select the oropharyngeal airway (its length is equivalent to front tooth to angle of mandible length) of suitable size, the patient is in patient's side then, breakdown patient oral cavity, the piped breather lower end edge of above-mentioned arc patient back is inserted downwards, the radian and the back bow of curved pipe are adapted, and the edge of a wing that breather top is outstanding places between patient's the lips and teeth, to guarantee that the breather end opening is positioned at the suitable position of bottleneck throat, the edge of a wing stably is clamped between patient's lips and teeth, breather is suitable for reading to be that inflatable mouth is positioned at outside the oral cavity, so that be connected with air bag or respirator.

This utility model is applicable to the artificial respiration in the cardio-pulmonary resuscitation process, have the usefulness of patient's airway that has completeness or part upper respiratory tract to block after the induction of anesthesia and/or need the unconsciousness of bite-block simultaneously concurrently, also help the attraction of the pharyngeal long-pending expectorant of patient, can have the function of airway concurrently to snoring, breathe sleep time-out syndrome patient simultaneously, thereby be suitable at clinical expansion.

Claims

1. an oropharyngeal airway is characterized in that described oropharyngeal airway adopts a curved pipe structure, and breather top is provided with the edge of a wing greater than this external diameter of pipe, and the breather on top, the edge of a wing partly is a pipe, and the breather of bottom, the edge of a wing partly is an elliptical tube.
