Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a novel endotracheal intubation kit. Background Technology

[0002] Endotracheal intubation is a technique that involves inserting a tube into the trachea through the glottis. This technique provides optimal conditions for airway patency, ventilation and oxygen supply, airway suction, and prevention of aspiration. It is widely used, especially in general anesthesia surgery. Currently, the most common endotracheal tubes are flexible tubes.

[0003] However, in otolaryngological surgeries, such as tonsillectomy and vocal cord surgery, the use of rigid instruments like mouth openers and laryngoscopes can compress the trachea, causing high pressure in the ventilator's airway and hindering anesthesia and ventilation. This is more common in pediatric surgeries. Furthermore, intubated patients often bite down on the tube, leading to deformation, compression, and damage. To avoid this, bite blocks are commonly used clinically to protect the trachea; however, bite blocks can impede the convenience of oral care and other procedures performed by healthcare professionals.

[0004] Therefore, the aforementioned technical defects urgently need to be addressed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a new type of endotracheal intubation kit, which aims to prevent the tracheal body from being squeezed and deformed by rigid instruments such as mouth openers and laryngoscopes, and thus avoid affecting the air flow of the tracheal body.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: A novel endotracheal intubation kit, comprising:

[0007] The tracheal body is used to deliver oxygen to the patient.

[0008] The outer tube is fitted onto the tracheal body and is slidably connected along the extension direction of the tracheal body. The outer tube is used to prevent deformation of the tracheal body.

[0009] The outer tube is equipped with a fastening structure, which has a fastened state that fixes the outer tube and the trachea body together, and a loosened state that allows the outer tube to slide along the trachea body.

[0010] In one possible implementation, a fastening nut is screwed to one end of the outer sleeve in the axial direction, and a beveled step is provided on one end of the outer sleeve. An abutting step is provided on the fastening nut at the position corresponding to the beveled step, and the beveled step and the abutting step abut against each other.

[0011] The fastening nut is used to adjust the diameter of the outer sleeve, and the fastening nut and the beveled step form a fastening structure.

[0012] In one possible implementation, several notches are evenly spaced along the axial direction of the outer sleeve on the oblique step.

[0013] In one possible implementation, the outer wall of the fastening nut is provided with anti-slip texture.

[0014] In one possible implementation, a fixation cuff is provided on the trachea body, which is used to fix one end of the trachea body in the patient's trachea.

[0015] In one possible implementation, the fastening nut is screwed onto the outer tube at the end opposite to the fixed airbag.

[0016] In one possible implementation, the outer sleeve is a transparent sleeve.

[0017] In one possible implementation, the outer sleeve is a polypropylene sleeve.

[0018] Compared with the prior art, this application provides a novel endotracheal intubation kit. In use, the outer tube can be slid down to the section of the trachea body closest to the patient's mouth. The outer tube withstands the compressive force of rigid instruments such as mouth openers and laryngoscope supports, preventing the trachea body from being compressed and deformed, and avoiding any impact on the airflow to the trachea body.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0028] This utility model provides, for example Figure 1 , Figure 2As shown, a novel endotracheal intubation kit can be inserted through the patient's glottis and can be used for airway patency, ventilation and oxygen supply, airway suction, and prevention of aspiration. Its main structure includes a tracheal body and an outer tube. The tracheal body delivers oxygen to the patient and, in some scenarios, can also be used to clear the patient's airway or suction foreign objects from the airway. The outer tube is fitted onto the tracheal body and slides along the extension direction of the tracheal body. The outer tube is a rigid tube, preventing easy deformation by external force. Therefore, the outer tube is used to prevent deformation of the tracheal body. The outer tube has a fastening structure that provides a secure connection between the outer tube and the tracheal body, and a loosened state that allows the outer tube to slide along the tracheal body. That is, when the outer tube is not needed, it can be moved to the end away from the patient's mouth, and the fastening structure can fix the outer tube in a position away from the patient's mouth, preventing the outer tube from interfering with the operation of medical personnel. When an outer tube is needed to protect the trachea, switch the outer tube to the loose position and move it to the patient's mouth. Then switch the outer tube to the tight position to prevent it from slipping out of the patient's mouth.

[0029] It should be noted that in ENT surgeries, such as tonsillectomy and vocal cord surgery, the use of rigid instruments like mouth openers and laryngoscopes can compress the trachea, causing high pressure in the ventilator's airway and hindering anesthesia and ventilation. This is more common in pediatric surgeries. Additionally, intubated patients often bite on the tube, leading to deformation, compression, and damage. To avoid this, bite blocks are commonly used clinically to protect the trachea; however, bite blocks can impede the convenience of oral care and other procedures performed by healthcare professionals.

[0030] In use, this invention allows the outer tube to be slid down to the section of the trachea closest to the patient's mouth. The outer tube absorbs the pressure from rigid instruments such as mouth openers and laryngoscopes, preventing deformation of the trachea and ensuring proper airflow. Furthermore, a fastening mechanism allows the outer tube to be fixed at any position on the trachea, thus increasing its flexibility in use.

[0031] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, a fastening nut is screwed to one end of the outer sleeve in the axial direction. A beveled step is provided on one end of the outer sleeve, and an abutment step is provided on the fastening nut corresponding to the beveled step. The beveled step and the abutment step abut against each other. The fastening nut is used to adjust the bore size of the outer sleeve, and the fastening nut and the beveled step form a fastening structure. That is, in the tightened state, the fastening nut is screwed in along the end of the outer sleeve; in the loosened state, the fastening nut is screwed out along the end of the outer sleeve.

[0032] In this embodiment, when the fastening nut is screwed in along the end of the outer sleeve, the abutting step on the fastening nut abuts against the oblique step of the outer sleeve, and the abutting force between the two gradually increases, causing the oblique step to shrink towards the central axis of the outer sleeve, thereby reducing the inner diameter of the outer sleeve and making the outer sleeve fit tightly on the trachea body.

[0033] Furthermore, such as Figure 2 As shown, several notches are evenly spaced along the axis of the outer sleeve on the beveled step. These notches allow the beveled step to taper slightly towards the central axis of the outer sleeve, making the inner diameter of the outer sleeve adjustable.

[0034] Furthermore, such as Figure 2 As shown, the outer wall of the fastening nut has anti-slip grooves. Understandably, when medical staff need to tighten the nut, the anti-slip grooves increase the friction between their fingers and the outer wall of the nut, preventing slippage.

[0035] Furthermore, such as Figure 1 As shown, a fixing cuff is provided on the trachea body, which is used to fix one end of the trachea body into the patient's trachea. Furthermore, an air inflator is connected to the fixing cuff, which extends to an external air inflator, allowing the air inflator to inflate and deflate the fixing cuff through the air inflator.

[0036] Understandably, when medical staff perform endotracheal intubation, they deflate the fixation cuff, reducing its size, and then insert one end of the endotracheal tube into the patient's trachea. The fixation cuff is then positioned inside the cuff. The cuff is then inflated, causing it to expand and press against the inner wall of the patient's trachea, thus securing the endotracheal tube.

[0037] Furthermore, such as Figure 1 As shown, the fastening nut is screwed onto the end of the outer tube opposite to the fixation cuff. It should be noted that positioning the fastening nut on the end of the outer tube opposite to the fixation cuff allows medical personnel to easily push the support portion of the outer tube (the end of the outer tube furthest from the fastening nut) into the patient's mouth. Furthermore, the fastening nut is still exposed outside the patient's mouth, allowing medical personnel to easily rotate and clamp the endotracheal tube, preventing it from loosening.

[0038] Furthermore, the outer cannula is a transparent cannula. Understandably, configuring the outer cannula as transparent allows medical staff to easily observe the connection between the outer cannula and the trachea.

[0039] Furthermore, the outer sheath is made of polypropylene. Polypropylene (PP) is a thermoplastic polymer polymerized from propylene monomers. It possesses high rigidity, wear resistance, and impact resistance. In the medical field, polypropylene is also widely used in the production of syringes, surgical instruments, and other medical devices.

[0040] In summary, this application provides a novel endotracheal intubation kit. During use, the outer tube can be slid down to the section of the trachea body closest to the patient's mouth. The outer tube withstands the compressive force from rigid instruments such as mouth openers and laryngoscopes, preventing the trachea body from being deformed and thus avoiding any impact on airflow.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
