Description

Technical Field

[0001] The utility model relates to the technical field of nasopharyngeal airway tubes, in particular to a detachable extended nasopharyngeal airway tube. Background Art

[0002] The nasopharyngeal airway is an artificial airway inserted into the pharynx through the nasal cavity. It is used to be inserted into the pharynx through the unilateral nasal cavity to displace the soft tissue of the pharynx to achieve the purpose of upper respiratory tract ventilation, and relieve or alleviate the patient's upper respiratory tract ventilation or obstruction. The nasopharyngeal airway is generally made of soft silicone or plastic material, and is a slightly curved cylindrical tube, similar to a non-balloon endotracheal tube, but shorter, and the tube wall is thinner and softer, with moderate hardness, and its length increases with the increase of the inner diameter.

[0003] The insertion length of most existing nasopharyngeal airways is determined by doctors based on their experience. The insertion depth of the airway tube cannot be observed and cannot be adjusted according to the patient's specific condition, which can easily cause blockage, poor ventilation effect, and intraoperative bleeding, severe respiratory depression, severe airway obstruction, etc., which is difficult to improve ventilation.

[0004] In view of the above problems, we propose a detachable extended nasopharyngeal airway tube. Utility Model Content

[0005] The utility model aims to provide a detachable extended nasopharyngeal airway tube to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A detachable extended nasopharyngeal airway tube, comprising:

[0008] A nasopharyngeal airway tube, a tube port at one end of the nasopharyngeal airway tube, and an extension tube extending from the other end, wherein the port of the extension tube is provided with a Murphy hole;

[0009] One end of the extension tube extending into the nasopharyngeal airway tube is connected to a connecting tube, and the outer wall of the connecting tube is provided with two annular grooves and a sealing ring;

[0010] The bottom of the nasopharyngeal airway tube is sleeved with two elastic rings.

[0011] Preferably, the annular groove corresponds to the elastic ring.

[0012] Preferably, an inflatable balloon is sheathed on the exterior of the extension tube, the inflatable balloon is connected to an air tube, the air tube is connected to an indicator balloon, the indicator balloon is connected to an inflation valve, and the inflation valve is connected to an inflation port.

[0013] Preferably, the inflation balloon, trachea, indicator balloon, inflation valve and inflation port are connected.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model can effectively improve the situation of secondary injury caused by reintubation, delayed rescue time, etc. by extending the component, making it easier for the visual probe to perform irradiation and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a detachable extended nasopharyngeal airway tube comprises:

[0023] A nasopharyngeal airway tube 1, a tube port 2 at one end of the nasopharyngeal airway tube 1, an extension tube 3 passing through the other end, a Murphy hole 4 is opened at the port of the extension tube 3, an inflatable balloon 8 is sleeved on the outside of the extension tube 3, the inflatable balloon 8 is connected to a trachea 9, the trachea 9 is connected to an indicator balloon 10, the indicator balloon 10 is connected to an inflation valve 11, the inflation valve 11 is connected to an inflation port 12, the inflatable balloon 8, the trachea 9, the indicator balloon 10, the inflation valve 11 and the inflation port 12 are connected, the nasopharyngeal airway tube can be inserted into the pharyngeal cavity through a single nasal cavity to displace the soft tissue of the pharyngeal cavity and achieve the purpose of upper respiratory tract ventilation, when the nasopharyngeal airway tube is not long enough or the ventilation condition cannot be improved. When the situation occurs, there is no need to remove the nasopharyngeal airway tube and change it to endotracheal intubation for direct use. As an extension component, the extension component can be placed in the main bronchus under the guidance of a visual fiberoptic bronchoscope for use as an endotracheal intubation. When a patient using an ordinary nasopharyngeal airway experiences heavy bleeding, nausea, reflux, suffocation, etc. during surgery, the airway can be protected and kept unobstructed by adding an extension component. Then, the inflation valve 11 is opened, and the gas inflation port 12, the indicator balloon 10 and the trachea 9 are introduced into the interior of the inflation balloon 8, so that the inflation balloon 8 gradually expands, the airway can be opened, and the visual probe can be inserted through the nasopharyngeal airway tube 1 and the extension tube 3 for irradiation to increase the operating field of view.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, one end of the extension tube 3 extending into the nasopharyngeal airway tube 1 is connected to a connecting tube 5, and the outer wall of the connecting tube 5 is provided with two annular grooves 6 and a sealing ring 13;

[0025] Two elastic rings 7 are sleeved on the bottom of the nasopharyngeal airway tube 1, and the annular groove 6 corresponds to the elastic ring 7. The hard connecting tube 5 at the end of the extension tube 3 can be inserted into the interior of the nasopharyngeal airway tube 1, and the elastic ring 7 is aligned with the annular groove 6 and sleeved on the nasopharyngeal airway tube 1. The nasopharyngeal airway tube 1, the connecting tube 5 and the extension tube 3 can be connected, and the sealing performance of the nasopharyngeal airway tube 1 and the connecting tube 5 can be improved by the sealing ring 13.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
