Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an oropharyngeal airway. Background Technology

[0002] An oropharyngeal airway, also known as an oropharyngeal endotracheal tube, is a rigid, flat, artificial airway made of elastic rubber or plastic. It is curved, with a curvature similar to that of the tongue and soft palate, making it easy to insert. Clinically commonly used oropharyngeal airways are oval-shaped hollow plastic tubes, shaped like an "S," which can rapidly open the patient's airway within seconds without the need for special instruments.

[0003] In existing technologies, oropharyngeal airways are mostly elliptical hollow through-hole structures. During surgery, all instruments are located in the elliptical channel at the same time. When suctioning and oxygen supply are required simultaneously, short-circuiting can easily occur, and the suction tube may suck away most of the oxygen introduced into the airway. This results in low suctioning efficiency and safety hazards, and cannot meet the needs of the operation. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides an oropharyngeal airway, including a baffle plate. The baffle plate is fixedly connected to one end of a straight pipe section, and the other end of the straight pipe section is fixedly connected to a curved pipe section. The baffle plate, the straight pipe section, and the curved pipe section are all provided with air passages. A channel structure is provided on both sides of the air passages. Each channel structure extends from one end face of the baffle plate to the other end face of the curved pipe section.

[0005] Preferably, the channel structure includes a first cavity and a second cavity, which are symmetrically arranged.

[0006] Preferably, the first cavity is located on one side of the ventilation cavity, and the second cavity is located on the other side of the ventilation cavity, wherein the ventilation cavity is used to isolate the first cavity and the second cavity.

[0007] Preferably, the inner diameter of the first cavity and the second cavity is smaller than the inner diameter of the ventilation cavity.

[0008] Preferably, the straight pipe section and the baffle plate are integrally formed, and a limit seam is provided at the end of the straight pipe section.

[0009] Preferably, the outer diameter of the limiting bite is larger than the outer diameter of the straight pipe section.

[0010] Preferably, two pagoda connectors are fixed on the baffle plate, one pagoda connector is connected to the first cavity, and the other pagoda connector is connected to the second cavity.

[0011] Preferably, the straight pipe section and the curved pipe section are integrally formed, and the limiting joint is located between the straight pipe section and the curved pipe section.

[0012] Preferably, the baffle plate has fixing holes on both sides, and the two fixing holes are symmetrically distributed.

[0013] Preferably, the curved pipe section has a rounded corner at its end.

[0014] The technical effects and advantages of this invention are as follows: 1. In this invention, by setting a channel structure on both sides of the ventilation cavity, sputum suction and oxygen supply are separated, and the two can be used independently during surgery, reducing the risk of short circuit, greatly reducing the amount of oxygen sucked away by the suction tube, improving the safety of surgery, and improving the efficiency of sputum suction to meet work requirements.

[0015] 2. In this invention, the ventilation cavity serves as the main channel during surgery. Through instruments such as endoscopes, the ventilation cavity, located in the middle of the overall oropharyngeal ventilation channel, can act as a barrier, isolating the suction channel and the oxygen supply channel from each other, reducing the risk of short circuits, and improving suction efficiency and oxygen supply stability.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Please see Figure 1-4As shown, this embodiment provides an oropharyngeal airway, including a baffle plate 1. The baffle plate 1 is fixedly connected to one end of a straight pipe section 2, and the other end of the straight pipe section 2 is fixedly connected to a curved pipe section 3. The baffle plate 1, the straight pipe section 2, and the curved pipe section 3 are all provided with air passages 220. A channel structure is provided on both sides of the air passage 220. Each channel structure extends from one end face of the baffle plate 1 to the other end face of the curved pipe section 3.

[0020] Specifically, during the surgery, the ventilation channel 220 is used to insert surgical instruments. One channel structure is connected to a suction tube for suctioning sputum, and the other channel structure is connected to an oxygen supply tube for introducing oxygen.

[0021] Furthermore, the curved pipe section 3 has a U-shaped or elliptical cross-section along the radial direction. The ventilation cavity 220 is located in the middle of the overall oropharyngeal airway. The ventilation cavity 220 has a circular cross-section along the radial direction, which allows the curved pipe sections 3 on both sides of the ventilation cavity 220 to have space for setting channel structures. Moreover, the curved pipe section 3 at the channel structure has a thicker wall, which makes the overall stability of the oropharyngeal airway higher.

[0022] The inventors have discovered that, compared to the prior art, by setting a channel structure on both sides of the ventilation cavity 220, sputum suction and oxygen supply are separated and used independently during surgery, reducing the risk of short circuits, greatly reducing the amount of oxygen sucked away by the suction tube, improving the safety of the surgery, and increasing the efficiency of sputum suction to meet work requirements.

[0023] Furthermore, the channel structure includes a first cavity 230 and a second cavity 240, which are symmetrically arranged. The first cavity 230 is located on one side of the ventilation cavity 220, and the second cavity 240 is located on the other side of the ventilation cavity 220. The ventilation cavity 220 isolates the first cavity 230 and the second cavity 240, preventing the suction tube from sucking away most of the oxygen during surgery and improving suction efficiency.

[0024] Preferably, the first cavity 230 and the second cavity 240 have the same inner diameter, the first cavity 230 and the second cavity 240 have the same shape, and the inner diameter of the first cavity 230 and the second cavity 240 is smaller than the inner diameter of the ventilation cavity 220.

[0025] Preferably, the center lines of the first cavity 230 and the second cavity 240 are at the same horizontal position, and the lengths of the first cavity 230 and the second cavity 240 are the same.

[0026] During the operation, the air pressure in the first cavity 230 and the second cavity 240 is similar, and the force on the oropharyngeal airway is uniform, which reduces the shaking of the oropharyngeal airway during the operation and thus improves the safety of the operation.

[0027] In one specific embodiment, the first cavity 230 is designated as the suction duct, which is connected to the suction device via a tubing. The second cavity 240 is designated as the oxygen supply duct, which is connected to the oxygen supply equipment via a tubing. The ventilation cavity 220 serves as the main channel during the operation and can be used with instruments such as an endoscope. Located in the middle of the overall oropharyngeal ventilation system, the ventilation cavity 220 can act as a barrier, isolating the suction duct and the oxygen supply duct from each other, reducing the risk of short circuits, and improving suction efficiency and oxygen supply stability.

[0028] Furthermore, the baffle plate 1 has fixing holes 210 on both sides. The two fixing holes 210 are axially symmetrically distributed and used to fix the rubber band. During the operation, it provides support for the oropharyngeal airway and is not easy to displace.

[0029] Furthermore, the baffle plate 1 is arc-shaped, and two pagoda connectors 100 are fixed on the baffle plate 1. One pagoda connector 100 connects to the first cavity 230, and the other pagoda connector 100 connects to the second cavity 240. Through the pagoda connectors 100, it can be adapted to various specifications of management, improving the versatility of the oropharyngeal tube.

[0030] Furthermore, the straight pipe section 2 and the baffle plate 1 are integrally formed, and a limiting bite 110 is provided at the end of the straight pipe section 2. The outer diameter of the limiting bite 110 is larger than the outer diameter of the straight pipe section 2. The straight pipe section 2 and the curved pipe section 3 are integrally formed, and the limiting bite 110 is located between the straight pipe section 2 and the curved pipe section 3.

[0031] In one embodiment, the limiting bite 110 has a ring-shaped protrusion structure, which can provide the patient with a biting position during surgery, especially under anesthesia, so that the oropharyngeal airway is not easily shaken or dislodged from the oral cavity by the pressure.

[0032] Furthermore, the outer wall of the straight pipe section 2 is provided with a flat surface to facilitate patient occlusion.

[0033] Furthermore, the end of the curved pipe section 3 is rounded to protect the patient's pharynx during use.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
