The oropharyngeal ventilation device is a hard flat tube artificial airway made of elastic rubber or plastic. It is curved, and its curvature is similar to that of the tongue. Oropharyngeal airways are mostly disposable devices.

[0003] For example, patent disclosure CN212973804U discloses a novel multi-purpose oropharyngeal ventilation device for anesthesiology and intensive care units, comprising: a main board, a bite plate, a main pipe, a first branch pipe, a second branch pipe and a fixing mechanism; the bite plate is arranged on one side of the main board, a temperature sensor is arranged on one side of the bite plate, a first branch pipe through hole, a main pipe through hole and a second branch pipe through hole are arranged on the main board and the bite plate, and the first branch pipe, the main pipe and the second branch pipe are respectively fixed in the first branch pipe through hole, the main pipe through hole and the second branch pipe through hole; the main pipe through hole is arranged at the center of the main board, the first branch pipe through hole and the second branch pipe through hole are respectively arranged on both sides of the main pipe through hole, and the length of the first branch pipe and the second branch pipe is less than the length of the main pipe; the fixing mechanism comprises: two arc-shaped fixing plates and two side strips, the two arc-shaped fixing plates are respectively arranged on both sides of the main board, the arc-shaped fixing plates are provided with joints, and the side strips are fixed to the arc-shaped fixing plates through the joints.

[0004] In the above solution, since the first branch pipe, the main pipe and the second branch pipe are fixedly connected to the main board and the bite plate, the first branch pipe, the main pipe and the second branch pipe cannot be replaced separately after use, and the entire device can only be replaced with a new one. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a multi-purpose oropharyngeal ventilation device for anesthesia. After the device is put into practical use, there is no need to replace the entire device. Only the connecting plate together with the ventilation tube needs to be disassembled and replaced, thus avoiding waste of resources.

[0006] The purpose of this disclosure can be achieved through the following technical solutions:

[0007] An anesthesia multi-purpose oropharyngeal ventilation device, comprising:

[0008] A connecting plate, to which a vent pipe is fixedly connected, and insert strips are fixedly connected on both sides of the connecting plate;

[0009] A fixing block, wherein the fixing blocks are arranged on both sides of the connecting plate, and slots for inserting the inserting strip are provided on the corresponding sides of the two fixing blocks, and a slide groove is provided on the upper end of the fixing block, and the slide groove is communicated with the slot, a slider is slidably connected in the slide groove, a toggle block is fixedly connected to the upper end of the slider, a guide rod is slidably connected to the toggle block, one end of the guide rod is fixedly connected to the side wall of the slide groove, and the other end is fixedly connected to a stopper, the stopper is fixedly connected in the slide groove and is located at the upper end of the slider, and a spring is sleeved on the guide rod.

[0010] The above technical solution, its principle and technical effect:

[0011] When the toggle block is toggled, the toggle block drives the slider to move so that the slider is disengaged from the slot. At this time, the inserting strip can be pulled out upwards to separate the connecting plate from the fixed block. At this time, the used connecting plate and the vent pipe can be replaced with new ones, and the inserting strip at the end of the new connecting plate is aligned with the slot and inserted into the slot. The toggle block is released, and under the elastic force of the spring, the toggle block drives the slider to move toward the slot, so that the slider is partially inserted into the slot and blocks the upper end of the inserting strip, so that the inserting strip cannot be disengaged from the slot.

[0012] Furthermore, the spring is arranged on the guide rod between the side wall of the slide groove and the toggle block.

[0013] Furthermore, it also includes a connecting belt, and both ends of the connecting belt are detachably connected to the fixing block.

[0017] Furthermore, the connecting rod is arranged on a side of the arc-shaped connecting plate away from human skin.

[0018] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0019] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0020] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0021] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0022] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0023] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0024] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0025] Beneficial effects of the present disclosure:

[0026] After the device is put into practical use, there is no need to replace the entire device. It is only necessary to dismantle the connecting plate together with the ventilation pipe and replace them, thus avoiding waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS
