Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a multifunctional oropharyngeal airway for fiberoptic bronchoscopy. Background Technology

[0002] In anesthesiology, we often encounter cases of anesthesia performed outside the operating room. Anesthesia outside the operating room carries a higher risk because it often involves intravenous general anesthesia without intubation, which lacks airway management and respiratory monitoring.

[0003] During anesthesia for bronchoscopy, non-intubated intravenous general anesthesia is sometimes required. When the anesthesia takes effect and the patient enters a sleep state, obese patients and patients with micrognathia may experience upper airway obstruction (tongue falling back), which requires intervention from the anesthesiologist to support the jaw or provide assisted ventilation, thus affecting the bronchoscopy procedure.

[0004] Under normal circumstances, an oropharyngeal airway can be placed through the mouth to solve the problem of tongue falling back and ensure ventilation. However, a conventional oropharyngeal airway can only lift the tongue and open the airway, but cannot provide access to a ventilator for ventilation and oxygen supply, or monitor the important indicator of end-tidal carbon dioxide.

[0005] Therefore, in order to solve the above problems, a multifunctional oropharyngeal airway for bronchoscopy is proposed. Through dual channels, it can provide ventilation and oxygen supply to the ventilator while opening the airway, and facilitate monitoring of end-tidal carbon dioxide. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional oropharyngeal airway for bronchoscopy, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional oropharyngeal airway for bronchoscopy, comprising an operating tube and a ventilator oxygen supply tube, wherein an airway is provided below the operating tube and the ventilator oxygen supply tube, a clamping plate is fixedly provided above the operating tube and the ventilator oxygen supply tube, and a carbon dioxide monitoring tube is adapted to be provided on one side above the ventilator oxygen supply tube.

[0008] Furthermore, the operating tube and the ventilator oxygen supply tube are connected to the ventilation duct.

[0009] Furthermore, the oxygen supply tube of the ventilator is positioned above the operating tube, and an interface is provided above the oxygen supply tube of the ventilator, which is adapted to connect to the ventilator.

[0010] Furthermore, the carbon dioxide monitoring tube is connected to the oxygen supply tube of the ventilator.

[0011] Furthermore, the card plate has symmetrically arranged strap openings on its surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The existing device is increased to a dual-channel system, namely the operation tube and the ventilator oxygen supply tube. The size of the operation tube can be set according to actual requirements to meet the needs of fiberoptic bronchoscopy.

[0014] (2) An interface is provided above the oxygen supply tube of the ventilator, so that the oxygen supply tube of the ventilator is higher than the operating tube, which facilitates the connection between the oxygen supply tube of the ventilator and the ventilator, so as to meet the purpose of supplying oxygen while opening the airway.

[0015] (3) Monitor end-expiratory carbon dioxide through the carbon dioxide monitoring tube on the upper side of the oxygen supply tube of the ventilator. Monitoring carbon dioxide is mainly to determine whether there is apnea.

[0016] (4) The symmetrical strap openings on the surface of the card plate can be directly fixed to the strap to avoid displacement or detachment during inspection. Attached Figure Description
