Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tracheal intubation device. Background Art

[0002] Tracheal intubation is a commonly used rescue technique in emergency work. It is one of the most widely used, effective and quickest means of respiratory management. It plays a vital role in saving patients' lives and reducing mortality.

[0003] The existing endotracheal intubation device includes a main catheter, the end of which is connected to a connector connected to a ventilator. The main catheter is retractable, and the inner diameter of the main catheter is smaller than the outer diameter of the connector. When the main catheter is sleeved on the outer surface of the connector, the main catheter is contracted so that the main catheter and the connector are connected more tightly together. During use, if an accidental collision occurs, there is a high probability that the main catheter and the connector will be separated, which poses a great risk to the patient's breathing safety.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-4 As shown, a tracheal intubation device includes a main conduit 1 and a connector 2, the upper end of the main conduit 1 and the lower end of the connector 2 are both provided with an epitaxial ring plate 3, and also includes a middle part for connecting the main conduit 1 and the connector 2, the middle part includes a folding tube 12, both ends of the folding tube 12 are respectively provided with elastic sleeves 4, the middle position of the sleeve 4 is provided with a accommodating cavity 5 for accommodating the epitaxial ring plate 3, the outer surface of the sleeve 4 is provided with an external thread, the main conduit 1 and the connector 2 are both movably connected with a nut 6, and the nut 6 is connected to the sleeve 4 by a thread.

[0019] The endotracheal intubation device also includes an air bag 10 and an inflation valve 11. The air bag 10 includes an outer air bag 10 and an inner air bag 10. There are two inflation valves 11, one of which is used to transport gas into the outer air bag 10, and the other is used to transport gas into the inner air bag 10. The endotracheal intubation device of the utility model has the same main structure and functional role as the existing endotracheal intubation device. The parts not described can adopt existing structures and do not affect the full disclosure of the utility model.

[0020] The connector 2 is connected to an external ventilator and delivers gas to the patient through the main catheter 1 to assist the patient's breathing. The existing connection between the connector 2 and the main catheter 1 is not tight enough. Under the patient's instinctive resistance and various possible collisions, there is a risk of the connector 2 and the main catheter 1 being separated. The utility model can reduce the risk of the main catheter 1 and the connector 2 being separated by strengthening the connection stability between the connector 2 and the main catheter 1.

[0021] When connecting the connector 2 to the main conduit 1, first, the sleeve 4 located at one end of the folding tube 12 is in an expanded state, so that the epitaxial ring plate 3 on the main conduit 1 can enter the sleeve 4, and then one end of the main conduit 1 is continuously pushed toward the inside of the sleeve 4. When the edge side of the epitaxial ring plate 3 can enter the accommodating cavity 5, the main conduit 1 is slightly pulled out of the sleeve 4 so that the epitaxial ring plate 3 can completely enter the accommodating cavity 5, and then the nut 6 on the main conduit 1 is moved, and the nut 6 is threadedly connected to the sleeve 4 to complete the connection between the sleeve 4 and the main conduit 1. The connector 2 is connected to another sleeve 4 in the same way, thereby realizing the connection between the main conduit 1 and the connector 2.

[0022] Since the epitaxial ring plate 3 is located inside the accommodating cavity 5 and cooperates with the thread on the nut 6 and the sleeve 4, the connection stability between the main conduit 1 and the sleeve 4, and between the connector 2 and the sleeve 4 is greatly improved, and the folding tube 12 is effectively prevented from separating from the main conduit 1 and the connector 2. At the same time, when a collision occurs, the impact force on the folding tube 12 can be reduced through the extension and deformation of the folding tube 12, and will not cause serious impact on the connection between the sleeve 4 on the folding tube 12 and the main conduit 1 and the connector 2.

[0023] Furthermore, the folding tube 12 has an outer convex portion and an inner concave portion, and the inner concave portion of the folding tube 12 is provided with a support ring 7, which is fixedly connected to the folding tube 12. The support ring 7 can keep the interior of the folding tube 12 always having a large ventilation space, thereby preventing the folding tube 12 from being squeezed and the internal space of the folding tube 12 being insufficient to affect the ventilation volume.

[0024] Furthermore, a reinforcing tube 8 is provided inside the main conduit 1 and the connecting head 2. The reinforcing tube 8 is used to prevent the main conduit 1 and the connecting head 2 from being severely deformed when the nut 6 is threadedly connected to the sleeve 4, thereby affecting the connection sealing of the main conduit 1, the connecting head 2 and the sleeve 4.

[0025] Furthermore, the outer surface of the epitaxial ring plate 3 is provided with separation gaps 9 , and the provided separation gaps enable the epitaxial ring plate 3 to be more conveniently folded, so that the epitaxial ring plate 3 can be inserted into the sleeve 4 .

[0026] Furthermore, the thickness of the epitaxial ring plate 3 gradually increases from the outside to the inside. When the epitaxial ring plate 3 moves in the sleeve 4, due to the relatively thin thickness of the outer side of the epitaxial ring plate 3, it can more conveniently enter the accommodating cavity 5. Then, as the epitaxial ring plate 3 is pulled out of the sleeve 4, the epitaxial ring plate 3 located in the accommodating cavity 5 abuts against the accommodating cavity 5, so that the epitaxial ring plate 3 continuously extends into the accommodating cavity 5 until the epitaxial ring plate 3 completely enters the accommodating cavity 5. At this time, the epitaxial ring plate 3 is stopped from being pulled out of the sleeve 4. The accommodating cavity 5 can improve the connection stability between the main guide tube 1, the connector 2 and the sleeve 4, and the upper and lower surfaces of the epitaxial ring plate 3 are in contact with the upper and lower surfaces inside the accommodating cavity 5, thereby improving the sealing performance of the connection.

[0027] The device achieves a stable connection between the main conduit 1 and the connector 2 by placing the epitaxial ring plate 3 in the accommodating cavity 5 and threadedly connecting it to the sleeve 4 through a nut 6. The folding tube 12 is provided so that when the main conduit 1 or the folding tube 12 is hit, the impact force on the main conduit 1 and the folding tube 12 can be weakened through the extension and compression of the folding tube 12, thereby ensuring that the main conduit 1 and the connector 2 can still be stably connected to the sleeve 4, thereby improving the safety of the device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
