Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adapter for endotracheal intubation in difficult airways. Background Technology

[0002] In difficult airway management, the endotracheal tube adapter (also known as an endotracheal tube connector or endotracheal tube adapter) is a crucial piece of equipment. In this context, the adapter is typically placed externally, meaning it connects to the outside of the endotracheal tube. This adapter is primarily used to connect the endotracheal tube to a ventilator or other respiratory support equipment, helping to maintain the patency and openness of the airway.

[0003] For example, a multifunctional adapter for endotracheal intubation in difficult airways guided by a fiberoptic bronchoscope, disclosed in CN221771180U, includes a main tube and a branch tube, which are connected. The external interface of the main tube can be connected to a fiberoptic bronchoscope. The branch tube includes a first interface, a second interface, and a third interface. The first interface is an oxygen input interface, which can be connected to an oxygen tube. The second interface is a negative pressure connection port, which can be connected to a negative pressure suction device. The third interface is a one-way injection interface, which can inject topical anesthetics or saline into the branch tube. The negative pressure connection port is equipped with a one-way valve. When the negative pressure suction device is working, the one-way valve is open, and when the negative pressure suction device is stopped, the one-way valve is closed. It can perform negative pressure suction when necessary while ensuring continuous oxygen input, thus simultaneously ensuring oxygen supply and removing secretions from the airway.

[0004] The aforementioned patent proposes that both the first and second interfaces are provided with threaded devices on their outer sides to fix the connecting pipe and increase the airtightness of the interfaces. However, in actual use, the structure of the threads relies on rotation locking. This connection method may be affected by pressure, vibration or external force, especially when the patient's position changes or the equipment is adjusted, which may lead to loosening or incomplete connection, easy air leakage, and inconvenience in use.

[0005] Therefore, we propose an adapter for endotracheal intubation in difficult airways to address the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide an adapter for endotracheal intubation in difficult airways, in order to solve the problems mentioned in the background art, such as changes in patient position, causing the trachea to loosen and leak air.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adapter for endotracheal intubation in difficult airways, comprising an adapter structure, wherein the adapter structure includes an inner component and a fixing tube installed at the top of the inner component, and an inhalation tube is installed inside the fixing tube and at the top of the inner component.

[0008] An adjustment groove is provided through the middle of the inner component, a rotating groove is provided at the top of the inner component and outside the adjustment groove, a fixing bend is installed at the top of the inner component and inside the rotating groove, and a bend groove is provided at both ends of the fixing bend.

[0009] Both sides of the bottom end of the air intake pipe are equipped with external insertion frames, and an external bending groove is opened through the middle of the external insertion frame.

[0010] Preferably, a top connecting ring is installed at the top of the inner connecting member and inside the rotating groove, and a sealing ring is installed on the inner wall of the top connecting ring.

[0011] Preferably, an inner bend strip is installed on both sides of the inner wall of the fixed tube, and a bent insert strip is installed on one side of the outer surface of the inner bend strip.

[0025] An adjustment groove 111 is provided through the middle of the inner component 11. A rotating groove 114 is provided at the top of the inner component 11 and outside the adjustment groove 111. A fixing bend 116 is installed at the top of the inner component 11 and inside the rotating groove 114. A bend groove 117 is provided through both ends of the fixing bend 116.

[0026] Both sides of the bottom end of the suction pipe 14 are equipped with an outer frame 141. An outer bend groove 142 is opened through the middle of the outer frame 141, and the outer bend groove 142 communicates with the interior of the bend groove 117.

[0027] A top connecting ring 112 is installed at the top of the inner component 11 and inside the rotating groove 114. A sealing ring 113 is installed on the inner wall of the top connecting ring 112. The bottom end of the suction pipe 14 contacts the sealing ring 113 to seal the suction pipe 14 and the top connecting ring 112.

[0028] Both sides of the inner wall of the fixed tube 13 are equipped with inner bending strips 132. A bent insert strip 133 is installed on one side of the outer surface of the inner bending strip 132. The bottom end of the inner bending strip 132 is slidably installed on the top of the inner connecting member 11. The bent insert strip 133 is adapted to the inside of the bent through groove 117 and the outer bending groove 142.

[0029] The upper end of the inner wall of the rotating groove 114 is provided with a threaded groove A115, and the lower end of the outer surface of the fixed tube 13 is provided with a threaded groove B131. The fixed tube 13 with the threaded groove B131 is threaded into the interior of the rotating groove 114 with the threaded groove A115 to fix the position of the fixed tube 13.

[0030] In this embodiment: the end of the inspiratory tube 14 furthest from the outer frame 141 is installed on the ventilator, and the end of the inspiratory tube 14 closest to the outer frame 141 is inserted between the fixed tube 13 and the top connecting ring 112. The outer frame 141 is inserted on the outside of the fixed bend 116. After the outer bend groove 142 is aligned with the bend groove 117, the fixed tube 13 is held by hand, and the lower end of the fixed tube 13 with the threaded groove B131 rotates inside the rotating groove 114. Since the threaded groove A115 is opened on the upper end of the inner wall of the rotating groove 114, the bottom end of the inner bend 132 moves downward as the fixed tube 13 rotates. The top of the inner component 11 is rotated, and the inner side of the inner bend 132 contacts the outer side of the top ring 112. As the fixed tube 13 rotates, the bottom end of the suction pipe 14 contacts the top end of the sealing ring 113. The bent insert 133 is inserted into the inner cavity of the outer bend groove 142 and the bend through groove 117. While fixing the position of the fixed tube 13, the suction pipe 14 squeezes the sealing ring 113 to seal the seal between the sealing ring 113 and the suction pipe 14.

[0033] In this embodiment: An inner partition 118 is installed inside the adjustment groove 111 of the inner connecting member 11 to separate the inhalation and exhalation areas inside the adapter structure 1. This helps to reduce the mixing of respiratory gases, including oxygen, anesthetic gases, carbon dioxide, etc., between inhalation and exhalation, maintains the accurate concentration of anesthetic gases and oxygen, and prevents contaminants in the exhaled gas from flowing back into the inhaled gas, thereby reducing cross-contamination. Several sets of adjustment holes 15 are provided on the outside of the inner connecting member 11. The instruments used for testing can be inserted into the adjustment holes 15. The instruments pass through the adjustment holes 15 and enter the adjustment groove 111. The inner partition 118 guides one end of the instrument downward until it enters the human body through the inner tube 119. The outer protective ball 12 provided on the outer surface of the inner tube 119 opens the inside of the trachea to avoid affecting the normal use of the instruments or the trachea tube.

[0034] Working principle: The end of the suction pipe 14 near the outer insert frame 141 is inserted between the fixed pipe 13 and the top connecting ring 112.
