Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a catheter for fixing a tracheal intubation. Background Art

[0002] Tracheal intubation involves inserting a custom-made endotracheal tube through the mouth or nose, transglottis, and into the trachea or bronchus. However, traditional endotracheal intubation procedures still present numerous technical challenges, particularly regarding tube insertion and fixation, patient comfort and safety, and examination effectiveness.

[0003] Traditional endotracheal tube insertion is often limited by the physiological structure of the patient's mouth and pharynx, making it difficult to insert. Furthermore, any misalignment of the tube can easily irritate the patient's mouth and pharynx, causing nausea, vomiting, and even suffocation.

[0004] During endotracheal intubation, it is crucial to ensure the tube is inserted along a specific path to facilitate ventilation and oxygenation. However, conventional endotracheal tubes lack guidance during insertion, and misplacement can easily lead to intubation trauma, laryngeal, glottic, or tracheal submucosal bleeding or hematoma, and subsequent acute airway obstruction. Utility Model Content

[0005] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide a catheter for fixing the endotracheal tube, and the technical problems solved are as follows: how to reduce the patient's discomfort and suffocation risk during the insertion of the endotracheal tube, and how to improve the smoothness and accuracy of the endotracheal tube insertion.

[0006] In order to solve the problems of the prior art, the technical solutions of the present utility model are as follows:

[0007] A catheter for fixing a tracheal intubation comprises a main body and a connecting tube. The main body is in a long arc-shaped curved shape, with expansion wing plates extending horizontally on both sides of the bottom of the main body, an occlusal support surface provided on the top of the main body, an adapting arc piece provided at one end of the main body, grooves provided on both sides of the adapting arc piece, one side of the occlusal support surface is connected to the adapting arc piece, an air ventilation channel is provided inside the main body, a fitting groove is provided at the bottom of the main body, the fitting groove extends downward to the bottom end of the main body, a guide groove is provided at the top of the main body near the bottom end, a connecting tube is provided on one side of the main body, and one end of the connecting tube is slidably inserted into the interior of the air ventilation channel.

[0008] Preferably, annular grooves are equidistantly provided on the inner wall of one end of the ventilation channel close to the connecting pipe, and a clamping ring is equidistantly provided on the outer side of one end of the connecting pipe. The clamping ring is clamped in the corresponding annular groove. Through the cooperation between the clamping ring and the annular groove, a stable connection between the connecting pipe and the ventilation channel inside the main body is achieved.

[0009] Preferably, the inner edge of the groove is flush with the side wall of the main body, the upper surface of the extension wing plate and the lower surface of the occlusal support surface. The flush setting helps to reduce the friction and collision between the tracheal tube and the edge of the groove during insertion, reducing the risk of damage to the tracheal tube and the patient's oral and pharyngeal tissues.

[0010] Preferably, the connection points between the two sides of the main body and the expansion wing plates are arranged in an arc shape, and the arc connection design helps to reduce the irritation to the patient's oral cavity and pharynx during the insertion of the endotracheal tube.

[0011] Preferably, the main body, the expansion wing plate, the occlusal support surface and the adapting arc piece are integrally formed, and the integral forming ensures a tight connection and precise fit between the various components.

[0012] Preferably, the bottom end of the extended wing plate is arc-shaped, which helps to reduce irritation and damage to the patient's oral cavity and pharynx during the insertion of the endotracheal tube.

[0013] Preferably, lugs are symmetrically provided on the outer side of the connecting tube, and the lugs provide convenient gripping and operating points for medical personnel.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] The extended wing plates on both sides of the main body of the utility model provide a stable guiding path for the tracheal cannula, so that the tracheal cannula can enter the airway more smoothly along the predetermined path. At the same time, the adaptive arc plate and the groove design on both sides thereof further assist the insertion of the tracheal cannula, reducing resistance and errors during the insertion process.

[0016] The design of the fitting groove enables the catheter to fit the patient's oral and pharyngeal physiological structure more closely, reducing the irritation of the catheter to the patient's oral and pharyngeal areas, thereby improving the patient's comfort during the examination.

[0023] 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 the embodiments.

[0024] The catheter for fixing the endotracheal tube comprises a main body 1 and a connecting tube 2;

[0025] like Figures 1 to 5 As shown, the main body 1 is in the shape of a long arc, with expansion wing plates 3 extending horizontally on both sides of the bottom of the main body 1, an occlusal support surface 4 provided on the top of the main body 1, an adapting arc piece 5 provided at one end of the main body 1, grooves 6 provided on both sides of the adapting arc piece 5, one side of the occlusal support surface 4 is connected to the adapting arc piece 5, a ventilation channel 7 is provided inside the main body 1, a fitting groove 8 is provided at the bottom of the main body 1, the fitting groove 8 extends downward to the bottom end of the main body 1, a guide groove 9 is provided on the top of the main body 1 near the bottom end, a connecting pipe 2 is provided on one side of the main body 1, and one end of the connecting pipe 2 is slidably inserted into the interior of the ventilation channel 7;

[0026] The expansion wings 3 on both sides of the main body 1 play a key guiding role during the insertion of the endotracheal tube. When the endotracheal tube passes through the mouth and enters the pharynx, the expansion wings 3 can naturally fit on both sides of the mouth, providing a stable path for the endotracheal tube. This not only helps to reduce the irritation of the endotracheal tube on the mouth and pharynx, but also ensures that the endotracheal tube can enter the airway smoothly and accurately along the predetermined path.

[0027] The adapting arc piece 5 at one end of the main body 1 and the grooves 6 on both sides are designed to further assist in the insertion of the endotracheal tube. The head of the endotracheal tube can be easily inserted through the grooves 6 on both sides of the adapting arc piece 5 and continue to penetrate deeper along the guidance of the expansion wing plate 3. This design reduces the direct contact area between the endotracheal tube and the oral and pharyngeal tissues, reducing the risk of respiratory damage to the patient.

[0028] The ventilation channel 7 provided inside the main body 1 is a key part for oxygen delivery. During the endotracheal intubation process, the patient may experience a feeling of suffocation or difficulty breathing due to irritation of the pharynx. In this case, oxygen is delivered to the patient's body through the ventilation channel 7, which can effectively relieve the patient's feeling of suffocation and ensure his or her life safety during the examination.

[0029] One end of the connecting tube 2 is slidably inserted into the interior of the ventilation channel 7, and the other end is used to connect to the breathing circuit for oxygen supply and end-of-tidal monitoring, so that medical personnel can monitor the flow and concentration of oxygen in real time during the medical treatment process.

[0030] The bottom fitting groove 8 of the main body 1 is used to fit and accommodate the epiglottis when the catheter is inserted into the oral cavity, reducing stimulation and friction on the pharyngeal tissue, thereby reducing the patient's pain and discomfort. The guide groove 9 can provide a smooth transition surface to fit the soft palate, leaving a certain gap between the nasal passages and the trachea.

[0031] like Figures 1 to 5 As shown, annular grooves 10 are equidistantly provided on the inner wall of one end of the ventilation channel 7 near the connecting tube 2, and snap rings 11 are equidistantly provided on the outer side of one end of the connecting tube 2. The snap rings 11 are clamped in the corresponding annular grooves 10. These snap rings 11 can be accurately clamped in the corresponding annular grooves 10, thereby achieving a stable connection between the connecting tube 2 and the ventilation channel 7 inside the main body 1, making it convenient for medical personnel to quickly replace or adjust the connecting tube 2 when needed, thereby improving the convenience and flexibility of operation.

[0032] like Figures 1 to 5 As shown, the inner edge of the groove 6 is flush with the side wall of the main body 1, the upper surface of the expansion wing plate 3 and the lower surface of the occlusal support surface 4. The flush setting helps to reduce the friction and collision between the endotracheal tube and the edge of the groove 6 during the insertion process, reducing the risk of damage to the endotracheal tube and the patient's oral and pharyngeal tissues. At the same time, the flush edge of the groove 6 also allows the endotracheal tube to slide more smoothly along the groove 6 into the airway, improving the accuracy and comfort of insertion.

[0033] like Figures 1 to 5 As shown, the connection between the two sides of the main body 1 and the expansion wing plate 3 is arranged in an arc shape. The arc connection design helps to reduce the irritation to the patient's mouth and pharynx during the insertion of the tracheal tube. The arc edge can fit the physiological structure of the mouth and pharynx more naturally, avoiding the discomfort or damage that may be caused by sharp edges.

[0034] like Figures 1 to 5 As shown, the main body 1, the expansion wing plate 3, the occlusal support surface 4 and the adapting arc piece 5 are integrally formed, which simplifies the manufacturing process of the endotracheal intubation tube and reduces the production cost. At the same time, the one-piece design also ensures the tight connection and precise fit between the various components, avoiding performance degradation or safety hazards caused by loose or misaligned components.

[0035] like Figures 1 to 5 As shown, the bottom end of the extended wing plate 3 is arc-shaped, which helps to reduce irritation and damage to the patient's oral cavity and pharynx during the insertion of the tracheal tube. The arc-shaped bottom end can transition more smoothly to the patient's oral cavity and pharyngeal tissue, avoiding discomfort or scratches that may be caused by sharp edges.

[0036] like Figures 1 to 5 As shown, lugs 12 are symmetrically provided on the outer side of the connecting tube 2 , and the lugs 12 provide a convenient grip and operation point for medical personnel.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
