Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to an improved nasopharyngeal ventilation tube. Background Art
[0002] A nasopharyngeal airway is a medical device used to maintain patency of the upper respiratory tract and prevent suffocation and breathing difficulties. In actual use, the nasopharyngeal airway can be inserted into the patient's nasal cavity or oral cavity to introduce air into the lungs and help the patient maintain normal breathing. Since the length and structure of the nasopharyngeal airway are not variable, a limiting structure is provided on the nasopharyngeal airway that abuts against the nose tip to prevent the nasopharyngeal airway from being inserted too deeply into the human body. However, during use, the limiting structure will press against the patient's nose tip for a long time, causing the patient's nose to turn red and increasing the patient's discomfort. At the same time, the nasopharyngeal airway lacks a fixing device, and the patient may easily fall off during transfer. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an improved nasopharyngeal airway capable of improving the comfort of patients.
[0004] The utility model adopts the following technical solutions:

[0006] Furthermore, the fixing assembly includes a limiting groove extending inwardly from the end surface of the free end of the elastic sleeve and a locking tie provided on the elastic sleeve, wherein the locking tie is provided near the free end of the elastic sleeve.
[0007] Furthermore, the elastic sleeve includes a plurality of abutment blocks arranged at intervals on the surface opposite to the main body and a positioning portion arranged on the outer periphery of the elastic sleeve for the locking tie to pass through.
[0008] Furthermore, the cross section of the abutment block is triangular, and the top end thereof can be tightly abutted against the outer wall of the main tube.
[0009] Furthermore, there are two positioning parts, which are arranged relatively on the outer periphery of the elastic sleeve.
[0010] Furthermore, the main pipe body is provided with an indicating scale line which can indicate the position of the elastic sleeve.
[0011] Furthermore, the fixing belt includes a fixing ring that can be snapped onto the elastic sleeve, a first elastic belt connected to the fixing ring that can be sleeved behind the patient's head, and a second elastic belt arranged in the middle of the first elastic belt that can be sleeved on the top of the patient's head.
[0012] Furthermore, the airbag includes an airbag body arranged in a ring shape and an air delivery port arranged on a side of the airbag body close to the interface.
[0013] Furthermore, the main body further includes a pharyngeal end provided at the other end of the main body, and a plurality of semicircular grooves are provided at intervals on the end surface of the pharyngeal end.
[0014] Furthermore, the main body, the interface and the pharyngeal end are integrally formed.
[0015] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are as follows: the present application defines the specific structure of the nasopharyngeal airway, so that the main body is detachably provided on the main body through a movable sleeve located on the side close to the interface. After the main body enters the patient's pharynx through the nostrils, the medical staff adjusts and fixes the position of the elastic sleeve on the main body using the fixing assembly according to the position of the patient's nose, so that the airbag is fixed on the outside of the nostrils and presses against the patient's nose. Moreover, since the airbag is made of flexible material, the pressure exerted on the patient's nose is not large, which can prevent the patient's nose from turning red due to long-term pressure from the nasopharyngeal airway, thereby improving the patient's comfort. At the same time, a fixing belt is added to the movable sleeve, so that after the nasopharyngeal airway enters the patient's pharynx, the nasopharyngeal airway can be fixed to the patient's face, thereby preventing the nasopharyngeal airway from being separated from the patient's pharynx during the patient's transfer.
[0016] By cooperating between the limiting groove extending inward from the free end surface of the elastic sleeve and the locking strap provided on the elastic sleeve, the position of the movable sleeve on the main body can be changed according to the position of the patient's nose, thereby being suitable for different patients, thereby improving the practicality of the utility model;
[0017] By providing a plurality of abutment blocks at intervals on the surface opposite to the main body, the friction between the inner wall of the elastic sleeve and the outer periphery of the main body can be increased, so that the elastic sleeve is tightly fixed on the main body;
[0018] By providing a plurality of semicircular grooves at intervals on the end surface of the pharyngeal end, the main pipe can be prevented from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS
