Description

Technical Field

[0001] The utility model belongs to the technical field of medical assistance, and in particular relates to a gastroscopic oropharyngeal airway. Background Art

[0002] The oropharyngeal airway, also known as an oropharyngeal tracheal tube, is a non-invasive, non-tracheal airway that prevents tongue retraction, rapidly opens the airway, and establishes a temporary artificial airway. The oropharyngeal airway is a clinically important airway opening tool, the simplest, most effective, and economical airway aid. It is widely used in clinical emergency care and postoperative resuscitation after general anesthesia. However, placement of the oropharyngeal airway into the pharynx often leaves no additional space for operation, limiting its clinical application.

[0003] During gastric surgery, maintaining airway patency after anesthesia is a critical issue. Currently, the primary approach involves placement of an oropharyngeal or nasopharyngeal airway, supplemented by lateral decubitus positioning and mandibular support. However, conventional oropharyngeal airways cannot be used because they require central placement in the mouth, which conflicts with the position of a gastroscope. Nasopharyngeal airways are also not suitable for patients with nasal or inferior nasal meatus abnormalities. Due to the narrow lumen and fixed length of the tube, which is constrained by the nasal cavity, placement can sometimes be difficult. Utility Model Content

[0004] The purpose of the utility model is to provide a gastroscopic oropharyngeal airway. By providing a dental pad group with the function of connecting and supporting the oropharyngeal airway and the gastroscope, the oropharyngeal airway and the gastroscope tube are fixedly installed in the oropharynx of the patient, which is beneficial for the simultaneous installation of the gastroscope and the oropharyngeal airway in the patient's throat, thereby improving the convenience of surgical operation.

[0005] The purpose of the utility model is achieved by providing a gastroscopic oropharyngeal airway, comprising:

[0006] The dental pad set is used to limit the position of the entire pharyngeal airway in the throat;

[0007] a channel body, an end of which is fixedly connected to the bite block assembly; and

[0008] The bite pad group includes a first bite pad portion and a second bite pad portion, and the first bite pad portion and the second bite pad portion are integrally arranged in the transverse direction. The channel body includes an oropharyngeal airway and a gastroscope tube guide tube, and the oropharyngeal airway is connected to the first bite pad portion, and the gastroscope tube guide tube is connected to the second bite pad portion.

[0009] Furthermore, the first bite pad portion and / or the second bite pad portion is a bite pad baffle that matches the curvature of the lips.

[0010] Furthermore, the oropharyngeal airway includes a straight tooth pad tube connected to the tooth pad assembly and a pharyngeal curved tube connected to the other end of the straight tooth pad tube.

[0011] Furthermore, the straight tube of the dental pad and the pharyngeal curved tube are detachably connected.

[0012] Furthermore, the curvature of the gastroscope tube guide tube is consistent with that of the oropharyngeal airway, and the gastroscope tube guide tube is fixedly arranged on one side of the oropharyngeal airway.

[0013] Furthermore, the gastroscope tube guide tube is a circular tube channel or a semicircular channel.

[0014] Furthermore, the channel body is a medical rubber component.

[0015] Furthermore, the cross-section of the first bite pad portion is smaller than the cross-section area of ​​the second bite pad portion, and the diameter of the gastroscope guide tube is smaller than the diameter of the oropharyngeal airway.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, a bite pad group having a first bite pad portion and a second bite pad portion is provided to achieve installation and setting of the end portion of the channel body. More specifically, the channel body includes an oropharyngeal airway and a gastroscope tube guide tube. Since the oropharyngeal airway is connected to the first bite pad portion and the gastroscope tube guide tube is connected to the second bite pad portion, the installation and setting between the oropharyngeal airway and the gastroscope tube guide tube is more compact, and the relative installation and setting between the airway and the gastroscope tube guide tube can be achieved, which is conducive to the simultaneous guided placement of the oropharyngeal ventilation and gastroscope catheters into the patient's throat, and the convenient guidance and setting of the gastroscope pipeline to the patient's stomach through the gastroscope tube guide tube, thereby greatly reducing the inconvenience of medical staff in placing the oropharyngeal airway and gastroscope tube guide tube in the patient's throat at the same time.

[0018] 2. In the present invention, since the first and second bite pad parts are configured as bite pad baffles that match the curvature of the lips, it is beneficial for the entire device to be fixedly placed in the patient's oral cavity.

[0019] 3. In the present invention, by configuring the oropharyngeal airway as a straight tube with a dental pad and a pharyngeal curved tube, the oropharyngeal airway with a certain curvature reduces the foreign body sensation when the oropharyngeal airway is in the patient's throat. At the same time, the pharyngeal curved tube with the amplitude of the human throat can limit the patient's tongue root to a certain extent, reducing the problem of the patient's tongue root blocking the trachea and causing suffocation.

[0020] 4. In the present invention, the entire pipeline device can be disassembled by detachably connecting the straight tube of the dental pad and the pharyngeal curved tube, which is conducive to cleaning the inside of the pipeline.

[0021] 5. In the present invention, by fixing the gastroscope tube guide tube on one side of the oropharyngeal airway, the gastroscope tube can be passed through the preset gastroscope tube guide tube from one side of the oropharyngeal airway into the patient's body, wherein the gastroscope tube guide tube is set as a semicircular channel to minimize the space occupied by the gastroscope tube guide tube in the patient's body. Through the semicircular channel, it is only necessary to guide and install the gastroscope tube, which greatly improves the convenience of operation. BRIEF DESCRIPTION OF THE DRAWINGS

Since the oropharyngeal airway 5 is connected to the first bite pad part 3 and the gastroscope tube guide tube 6 is connected to the second bite pad part 4, the installation setting between the oropharyngeal airway 5 and the gastroscope tube guide tube 6 is more compact, and the relative installation setting between the airway and the gastroscope tube guide tube 6 can be achieved, which is conducive to the simultaneous guided placement of the oropharyngeal ventilation and gastroscope catheters into the patient's throat, and the convenient guidance of the gastroscope pipeline to the patient's stomach through the gastroscope tube guide tube 6, thereby greatly reducing the inconvenience of medical staff in placing the oropharyngeal airway 5 and the gastroscope tube guide tube 6 in the patient's throat at the same time.

[0034] Preferably, the first bite pad portion 3 and / or the second bite pad portion 4 is a bite pad baffle that matches the curvature of the lips.

[0035] It can be understood that since the first bite pad portion 3 and the second bite pad portion 4 are set as bite pad baffles that match the curvature of the lips, it is beneficial for the entire device to be fixedly placed in the patient's oral cavity.
