AI Technical Summary
When treating patients with upper airway obstruction, existing technologies require multiple bronchoscopic intubations, which are inconvenient and may cause damage. Furthermore, tracheotomy presents difficulties for both patients and their families, especially for those who refuse tracheotomy, as there is a lack of effective non-invasive ventilation and secretion clearance methods.
A nasal glottic airway was designed, comprising a catheter and a connector. The catheter has a flexible tip and a narrow diameter, allowing it to pass through the nasal cavity into the glottis. The connector matches the nasolabial groove, providing ventilation and secretion clearance channels. It is suitable for bronchoscopic guidance and suction catheter use.
It achieves minimally invasive ventilation of the upper respiratory tract and glottis, effectively improves respiratory function, reduces medical costs, and provides non-invasive ventilation and secretion clearance methods. It is suitable for patients who have not established an artificial airway or refuse tracheotomy.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a nasal glottic airway. Background Technology
[0002] Percutaneous tracheotomy is a minimally invasive surgical procedure with advantages such as minimal damage, rapid recovery, and fewer complications. In recent years, it has gradually replaced traditional tracheotomy, especially in the field of critical care medicine. Extensive literature and clinical practice demonstrate the necessity of bronchoscopic-guided percutaneous tracheotomy.
[0003] In the ICU, most patients undergoing tracheotomy have preoperative oral or nasal endotracheal intubation and have undergone prolonged mechanical ventilation. However, some patients do not have an artificial airway established before tracheotomy, primarily due to cerebrovascular disease or systemic illness leading to altered consciousness. During bronchoscopic-guided percutaneous tracheotomy in these patients, the bronchoscope needs to be inserted into the trachea through the nose, pharynx, and glottis for monitoring. The lack of an artificial airway makes multiple airway insertions by the bronchoscope inconvenient, and performing nasal or oral endotracheal intubation for this purpose would cause injury, while using it only during the procedure would be wasteful. Treating patients with upper airway obstruction whose families refuse tracheotomy also presents certain challenges. Utility Model Content
[0004] In view of this, the present invention aims to provide a nasal glottic airway, which has a smaller diameter than an endotracheal tube and a more flexible end, causing less damage to the upper respiratory tract and glottis, and can also serve as a passage for bronchoscopy. For patients with upper airway obstruction, the application of this invention can effectively ventilate and clear lower respiratory tract secretions, thereby improving respiratory function non-invasively and effectively reducing medical costs.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0006] A nasal glottic airway includes a tubing and a connector inserted at the top of the tubing. The lower end of the tubing is obliquely cut, and a side hole is provided on the side wall near the lower end of the tubing. Two side ears are symmetrically provided on the outer periphery of the connection port on the connector. Each of the two side ears is provided with a fixing hole, and a strap is attached to the head inside the two fixing holes.
[0007] Furthermore, the catheter is made of a flexible, soft, hollow material.
[0008] Furthermore, the catheter length is 15-20cm.
[0009] Furthermore, the side of the connector that contacts the nasolabial fold has an arc surface that matches the shape of the nasolabial fold.
[0010] Furthermore, the curved surface is provided with an extended surface that can increase the contact area between the connector and the nasolabial fold.
[0011] Furthermore, the connector is also provided with through holes arranged side by side with the connection port, and the connection port and through holes correspond to the positions of the two nostrils respectively.
[0012] Furthermore, the inner diameter of the catheter is 5.0-6.0 mm.
[0013] Furthermore, the oblique cut is a 50°±15° oblique plane.
[0014] Compared with the prior art, the nasal glottic airway of this invention has the following advantages:
[0015] The nasal glottic airway described in this invention has a smaller diameter and a more flexible tip than an endotracheal tube, resulting in less damage to the upper respiratory tract and glottis, and can also serve as a passage for bronchoscopy. For patients with upper airway obstruction but whose families refuse tracheotomy, this nasal glottic airway can effectively provide ventilation and clear lower respiratory tract secretions, thereby improving respiratory function non-invasively and effectively reducing medical costs.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0031] Example 1
[0032] like Figure 1-2As shown, a nasal glottic airway includes a tubing 1 and a connector 2 inserted at the top of the tubing 1. The lower end of the tubing 1 is a beveled surface 12 with a blunt rounded opening. A side hole 11 is provided on the side wall near the lower end of the tubing 1. The side hole facilitates gas flow when the lower end of the tubing is blocked. The connector can be connected to a simple respirator or a ventilator tubing. Two side ears 22 are symmetrically provided on the outer periphery of the connection port 21 on the connector 2. Each of the two side ears 22 has a fixing hole 23. A strap is attached to the head inside the two fixing holes 23.
[0033] For example, the material of conduit 1 is an elastic, soft hollow conduit.
[0034] For example, catheter 1 is 15-20cm long, specifically, it can be 20cm.
[0035] The inner diameter of catheter 1 is 5.0-6.0 mm.
[0036] The oblique cut is a 50°±15° oblique plane.
[0037] Specifically, the connector 2 should have a 15mm external tapered connector conforming to the YY1040.1-2003 standard; the connector and the vent should be firmly connected and should not separate under a static axial force of 15N for 15 seconds.
[0038] The catheter is arc-shaped, and the radius of the arc segment should be (140 ± 20) mm.
[0039] Example 2
[0040] Based on the above embodiment 1, the connector 2 has an arc surface 24 that conforms to the shape of the nasolabial fold on the side that contacts the nasolabial fold, such as... Figure 3 As shown, the curved surface can increase the comfort of the connector in contact with the skin.
[0041] For example, the arc surface 24 is provided with an extension surface 25 that can increase the contact surface between the connector 2 and the nasolabial fold, such as... Figure 4 As shown, the extended surface increases the contact area and improves the comfort of use.
[0042] Example 3
[0043] Based on the above embodiments 1 and 2, the connector 2 is further provided with a through hole 26 arranged parallel to the connection port 21. The connection port 21 and the through hole 26 correspond to the positions of the two nostrils, respectively. Figure 5 and 6 As shown, the through-hole design ensures unobstructed breathing.
[0044] like Figure 7 The diagram shown illustrates the current usage status of the nasal trachea. Figure 8This diagram illustrates the usage of the nasal glottic airway described in this invention. The nasal glottic airway can pass through the nose and pharynx, enter the glottis, and its end is located 1-3 cm below the glottis in the trachea. It can provide effective ventilation and a passage for bronchoscopes and suction catheters to clear secretions from the lower respiratory tract.
[0045] Application Scenario 1: For tracheostomy patients who have not yet established an artificial airway, a nasoglottic airway is inserted under bronchoscopic guidance, and the nasoglottic airway is used as an artificial airway for bronchoscope-guided percutaneous tracheostomy.
[0046] Application Scenario 2: For patients with upper airway obstruction, including those with impaired consciousness due to various causes or those with advanced malignant tumors, whose families often refuse tracheotomy to open the airway, the nasal glottic airway described in this utility model can be used to improve respiratory function.
[0047] Application Scenario 3: For patients with glottic dysfunction and insufficient airway self-cleaning ability after weaning from mechanical ventilation, this utility model can not only open the airway, but also serve as a suction catheter for clearing secretions from the lower respiratory tract, and as a bronchoscope for clearing the airway.
[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
