Abstract
The invention relates to a double cavity type oropharyngeal airway which comprises an airway body (1) and an oxygen mask (2), wherein the airway body (1) comprises a double-cavity soft airway; the front part of the airway body (1) is in a bent shape, and the back end of the airway body (1) is connected with the oxygen mask (2); outer vent holes (4) are arranged at the bent part of the airway body (1); wet sponge (3) is arranged in an inner cavity of the oxygen mask (2); and vent holes are arranged at the top or on the side wall of the oxygen mask (2). In the invention, the porous sponge is arranged and can cool water vapor, store water and slow down the drying speed of oral secretions; compared with a single cavity type oropharyngeal airway, the double cavity type oropharyngeal airway reduces the chances of blockage; special oxygen input ports are arranged on the oxygen mask, can ensure the supply speed of oxygen and avoid the defect that an air channel is blocked because an oxygen hose is inserted into the oropharyngeal airway in the prior art; and the arrangement of the outer vent holes can ensure the airway to be unobstructed.
Description
Technical field
The present invention relates to a kind of oropharyngeal airway, particularly relate to a kind of double cavity type oropharyngeal airway.Belong to field of medical appliances.
Background technology
In medical treatment clinically, much go into a coma, suffocate etc. needs the sick and wounded of first aid must carry out the artificial effectively breathing that helps fast, makes cardio-pulmonary resuscitation.At present, the method for the most effective fast quick-recovery breathing just is to use oropharyngeal airway.Existing oropharyngeal airway is simple in structure, but has following shortcoming: 1, existing oropharyngeal airway is that duroplasts is made, and can not change along with patient's oral cavity anatomical structure and change, and when patient respiratory moved, its top caused patient's pars oralis pharyngis hemorrhage easily; 2, existing oropharyngeal airway does not have humidification function, makes the suction gas drying, and the patient's that lies low pars oralis pharyngis secretions (comprising sputum) is very fast dry and hard, and the danger that causes airway obstruction is arranged; 3, the fixing trouble of Oxygen tube, and the airway of port blocked Pharynx trachea because place oxygen hose easily; 4, the fixing trouble of breather; When 5, the placement of oropharynx end was not good, its ventilation was obstructed easily.
Summary of the invention
Purpose of the present invention is in order to solve the shortcoming of existing oropharyngeal airway, a kind of double cavity type oropharyngeal airway to be provided.
Purpose of the present invention is achieved through the following technical solutions:
Double cavity type oropharyngeal airway comprises ventilation body and oxygen mask, it is characterized in that: the ventilation body is made of two-chamber software breather, and the front portion of ventilation body is bending, the rear end is connected with oxygen mask, is provided with outer vent at the bending section of the body of ventilating; The inner chamber of oxygen mask is provided with moistening sponge, and the top or the sidewall of oxygen mask are provided with passage.
Purpose of the present invention can also be achieved through the following technical solutions:
A kind of embodiment of realizing the object of the invention is: the rear portion of ventilation body is and separates shape, forms split type double cavity structure, and described split type double cavity structure is fixed by fixing head; The front portion of ventilation body is bending and links together, forms the Contiuum type double cavity structure, and the inner chamber of described Contiuum type double cavity structure is communicated with by interior passage.
A kind of embodiment of realizing the object of the invention is: described ventilation body flexibly connects by fixing head and oxygen mask, and the bottom of fixing head sealing oxygen mask makes the interior oxygen of oxygen mask enter human body by the bicavate body of ventilating; The end of ventilation body can partly insert in the oxygen mask.
A kind of embodiment of realizing the object of the invention is: the oxygen input port that is provided with communication with cavity at the sidewall of oxygen mask; Be provided with the oxygen cover cap with passage at the top of oxygen mask, the oxygen cover cap is connected with the oxygen mask cassette or other modes connect.
A kind of embodiment of realizing the object of the invention is: sponge is a mandruka in the described oxygen mask.
A kind of embodiment of realizing the object of the invention is: the forward crooked radian of described ventilation body and pars oralis pharyngis coincide, and outer vent is positioned at the inboard of flexure plane, helps patient's use.
A kind of embodiment of realizing the object of the invention is: described ventilation body is made by soft sebific duct.
A kind of embodiment of realizing the object of the invention is: described outer vent is more than two, is arranged on the cavity of ventilation body or is separately positioned on two cavitys of ventilation body; Described in passage be one, more than two or three.
The beneficial effect that the present invention has is as follows:
1, is provided with mandruka in the oxygen mask, not only can makes the steam cooling, and can store moisture, make inhaled air moistening, the dry and hard speed of the oral secretion that slows down; Double cavity type oropharyngeal airway is compared with single-chamber type simultaneously, more can reduce blocked chance.
2, oxygen mask is provided with special oxygen input port, not only can guarantee the feed speed of oxygen but also avoid existing oropharyngeal airway that oxygen hose is inserted breather and the shortcoming of blocking airway.
3, the ventilation body is made by the soft glue tube material, and the effect that it has again when having antagonism patient gmatjpdumamics according to patient's oropharynx characteristics plastotype has reduced the damage of patient's pars oralis pharyngis, alleviates patient's misery.
4, split type double cavity structure helps the fixing of breather; Being provided with of outer vent and interior passage can guarantee also can guarantee airway patency the patient because of the timesharing of the mobile breather pars oralis pharyngis of accident.
