Description

Technical Field

[0001] The present application relates to the technical field of respiratory apparatus, and in particular to an endotracheal tube with an improved bite block. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the oral or nasal cavity and the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction.

[0003] In order to prevent the patient from biting the oral endotracheal tube, a bite block is added to the endotracheal tube, such as Figure 1 The figure shows a mouth guard used in conjunction with an existing endotracheal tube. The mouth guard has an incompletely closed side hole for installing the endotracheal tube. When the mouth guard is placed in the mouth, the lateral dimension is significantly larger than the outer diameter of the endotracheal tube, so that the patient's mouth is opened to a greater extent when wearing it, and the patient feels obvious discomfort when wearing it for a long time.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0021] See attached Figure 2 As shown, the embodiment of the present application provides an endotracheal tube with an improved bite pad 3, comprising a tube body 1, a gas bag 2 is arranged at the front end of the tube body 1, a bite pad 3 is arranged at the end of the tube body 1, and the bite pad 3 comprises a first semicircular sleeve 301 and a second semicircular sleeve 302, the first semicircular sleeve 301 and the second semicircular sleeve 302 can be disassembled and assembled with each other, and the first semicircular sleeve 301 and the second semicircular sleeve 302 are assembled to embrace the tube body 1. Specifically, after the patient inserts the endotracheal tube, according to the positional relationship between the tube body 1 and the teeth, the first semicircular sleeve 301 and the second semicircular sleeve 302 are matched to wrap the tube body 1, and the first semicircular sleeve 301 and the second semicircular sleeve 302 are assembled into a whole to form a bite pad 3, which is located between the upper and lower teeth to prevent the endotracheal tube from being bitten through the oral cavity. At the same time, the improved bite pad 3 is in the shape of a sleeve and is close to the outer diameter of the endotracheal tube, so that the degree of mouth opening can be reduced and the patient's comfort can be improved.

[0022] In the above, the first semicircular sleeve 301 and the second semicircular sleeve 302 are fastened together by fasteners, which is convenient for disassembly and assembly of the dental pad 3 and provides convenience for use of the dental pad 3.

[0023] As a preferred embodiment, Figure 3 and Figure 4 As shown, the fastener includes a docking hole 4 provided on the connection end face of the first semicircular sleeve 301 and a buckle joint 5 provided on the connection end face of the second semicircular sleeve 302, and the buckle joint 5 is inserted and fixed in the docking hole 4. The connection end face is the edge face where the first semicircular sleeve 301 and the second semicircular sleeve 302 fit each other.

[0024] In order to ensure that the snap joint 5 can be fixed in the docking hole 4, in the present embodiment, the docking hole 4 is a stepped hole, and the docking hole 4 is located on the outside as a small-diameter hole section, and on the inside as a large-diameter hole section. The snap joint 5 includes a small-diameter shaft section and a spherical crown head. The small-diameter shaft section is integrally formed on the connecting end face of the second semicircular sleeve 302, and the spherical crown head is integrally formed on the other end of the small-diameter shaft section, wherein the outer diameter of the small-diameter shaft section is the same as and matches the inner diameter of the small-diameter hole section, and the diameter of the spherical crown head is the same as and matches the inner diameter of the large-diameter hole section. The snap joint 5 is made of elastic silicone material, so it can be imagined that when the first semicircular sleeve 301 and the second semicircular sleeve 302 are docked and pressed, the snap joint 5 can be squeezed into the docking hole 4 and fixed, so that the first semicircular sleeve 301 and the second semicircular sleeve 302 are assembled into a tooth pad 3, which has a simple structure and is easy to disassemble and assemble. Of course, it is conceivable that in order to ensure that the first semicircular sleeve 301 and the second semicircular sleeve 302 have better stability after being fixed, a plurality of groups of fasteners are provided along the connecting end surfaces of the first semicircular sleeve 301 and the second semicircular sleeve 302 .

[0025] In summary, the endotracheal tube with an improved bite pad 3 provided in the embodiment of the present application improves the bite pad 3 into a pair of sleeve structures that can be assembled with each other and fixed to the tube body 1, so that the outer diameter of the improved bite pad 3 is close to that of the tube body 1, and the lateral dimension of the improved bite pad 3 is obviously smaller than that of the existing bite pad 3. When the patient bites the bite pad 3, the degree of opening of the mouth becomes significantly smaller, so the comfort is better.

[0026] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
