specific Embodiment 1

[0023] Figure 1 ~ Figure 4 Constitute specific embodiment 1.

[0024] Such as figure 1 , figure 2 , Figure 4 As shown, the double-chamber oropharyngeal ventilation tube includes a ventilation tube body 1 and an oxygen mask 2 composed of a double-lumen soft ventilation tube. The front part 1-2 of the ventilation tube body 1 is curved and connected together to form a conjoined body A double-cavity structure, the conjoined double-chamber structure is provided with an outer vent hole 4 and an inner vent hole 5 to communicate with the inner cavity; the rear part 1-1 of the vent pipe body 1 is separated to form a split-type double-chamber structure, so The split-type double-chamber structure is fixed by the fixed plate 1-3; the fixed plate 1-3 is movably connected with the oxygen mask 2 to seal the bottom of the oxygen mask 2; the inner cavity of the oxygen mask 2 is provided with a moist porous sponge 3. The side wall is provided with an oxygen input port 2-1 communicating w...

specific Embodiment 2

[0025] The characteristics of this specific embodiment 2 are: the outer ventilation holes 4 can be provided with two, three, four, five, six, seven, eight, nine or more than ten, and can be arranged in a cavity It can also be set on two cavities. There can be one, two or more than three interior air holes 5 . All the other are with specific embodiment 1.

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 [0001] The invention relates to an oropharyngeal ventilation tube, in particular to a double-chamber oropharyngeal ventilation tube. It belongs to the field of medical equipment. Background technique [0002] In medical clinic, many wounded and sick who need first aid such as coma, suffocation, etc. must carry out fast and effective artificial assisted breathing to make cardiopulmonary resuscitation. Currently, the most effective way to quickly restore breathing is the use of an oropharyngeal airway. Existing oropharyngeal airway is simple in structure, but has the following disadvantages: 1. Existing oropharyngeal airway is made of hard plastic, which cannot change with the patient's oral anatomy. When the patient breathes, its top will easily cause the patient to Oropharyngeal hemorrhage; 2. The existing oropharyngeal ventilation tube has no humidification function, which makes the inhaled gas dry, and the oropharyngeal secretions (including sputum) of pa...
