Description

Technical Field

[0001] This utility model relates to the medical field, specifically to an anti-dislodgement endotracheal tube. Background Technology

[0002] The endotracheal tube is an important medical device in clinical practice. It is inserted into the trachea of ​​a patient who cannot breathe independently through endotracheal intubation and is a medical tool for establishing an airway during general anesthesia surgery.

[0003] Currently, general anesthesia surgeries such as gynecological transvaginal single-port laparoscopy, oral and facial surgery, neurosurgical craniotomy, orthopedic lumbar and cervical spine surgery, or other surgeries requiring special body positions such as lateral or prone positions, pose risks during endotracheal intubation due to factors such as difficulty in exposing the head and face, oral secretions, and gravity. These risks include poor mouth pad adhesion and endotracheal tube dislodgement and movement into the body, sometimes even requiring emergency assistance for secondary endotracheal intubation.

[0004] To ensure the safety of ventilation for patients under general anesthesia, a reliable and convenient endotracheal tube is needed to reduce the risk of endotracheal tube dislodgement and thus ensure the patient's life safety. Utility Model Content

[0005] The purpose of this invention is to provide an anti-dislodgement endotracheal tube that, through the cooperation of various components during surgery, achieves a stable state of the endotracheal tube, effectively maintains and ensures the normal operation of the artificial airway, avoids problems such as external displacement, dislodgement, and internal slippage of the endotracheal tube, improves the efficiency and safety of surgery, and thus increases the protection of the patient's life safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-dislodgement endotracheal tube includes a tube body, a limiting plate, and a deformable component. One end of the tube body is provided with a connector, and the other end of the tube body is provided with an air outlet and a fixing airbag. The fixing airbag is connected to an inflation connector via a branch tube. The limiting plate has a perforation in the middle and can be fitted onto the tube body near the connector. The limiting plate and the tube body can be detachably connected. The inside of the perforation is tightly wrapped with the endotracheal tube by a fastening component. The deformable component is provided on the tube body and is located on the inside of the corresponding tooth of the tube body.

[0008] Compared with existing technologies, the endotracheal tube designed to prevent dislodgement using the above-mentioned technical solution has the following advantages:

[0009] The endotracheal tube of this invention, through the cooperation of a limiting plate, a deformable component, and the tube body, can be fixed and limited on the outside and inside of the patient's teeth, thereby achieving a stable connection between this part of the tube body and the oral cavity. This achieves a restrictive effect on the entire tube body, avoiding the risk of external displacement or slippage. Furthermore, the fastening components increase the stability of the connection between the tube body and the limiting plate, thereby increasing the stability of the established artificial airway. At the same time, the shape-changing characteristics of the deformable component can be used to adapt to different oral cavity sizes. In addition, the detachable and assembleable limiting plate increases the flexibility of use, that is, by selecting different specifications of limiting plates to suit different mouth shapes, or according to the required airway length, the placement of the limiting plate on the tube body can be flexibly adjusted in conjunction with the fastening components.

[0010] Preferably, the fastening assembly includes an annular wall, a fastening airbag, an inflation connector, and a delivery pipe. The annular wall is fixedly located at the perforation position, and the fastening airbag is arranged around the inner side of the annular wall, with the airbag connected to the inflation connector via the delivery pipe. Through the coordinated use of the fastening airbag, inflation connector, and delivery pipe, the gap between the tube and the annular wall is effectively filled, tightening the endotracheal tube. When the endotracheal tube is subjected to force, the limiting plate, the annular wall, and the fastening airbag all provide a certain degree of resistance.

[0011] Preferably, the fastening assembly further includes an adhesive layer disposed on the surface of the fastening airbag, and the adhesive layer is made of an anti-slip material or has multiple anti-slip particles. The anti-slip properties of the adhesive layer surface increase the frictional resistance between the fastening airbag and the perforation, thereby further increasing the tightness and stability of the connection between the limiting plate and the tube.

[0012] Preferably, the deformable component is a limiting airbag mounted on the tube body, and the limiting airbag is connected to a transmission connector via a transmission tube. The deformable component can be a limiting airbag or a medical silicone component with an antibacterial layer on the outside. It can be appropriately deformed to adapt to the shape of the oral cavity. In this case, a limiting airbag structure is used, which facilitates subsequent removal operations when the limiting airbag is shrunken and deflated. Moreover, the volume of the limiting airbag can be controlled by the degree of gas inflation, which allows medical staff to make precise adjustments on the outside of the oral cavity, ensuring the blocking effect of the limiting airbag without excessively compressing the inside of the oral cavity.

[0013] Preferably, the limiting plate has multiple grooves, which are evenly spaced along the outer periphery of the limiting plate. These grooves facilitate the placement of the branch pipe, delivery pipe, and transmission pipe along the outer wall of the pipe body, thus placing the corresponding connector structures of these pipe fittings on the outside for easy adjustment. Furthermore, the multiple grooves also allow medical personnel to stably hold and adjust the position of the limiting plate.

[0014] Preferably, the end of the annular wall away from the connector does not extend beyond the end face of the limiting piece facing the side where the fixed airbag is located. The limiting piece does not have any additional protruding structure on the side facing the oral cavity, allowing for a stable fit with the outer edge of the teeth and the lip edge, further increasing the blocking and limiting effect, and avoiding excessive pressure on vulnerable areas such as the gums and lips.

[0015] Preferably, the connector has an embedding groove on the side facing the limiting piece, and the embedding groove is adapted to the annular wall and the fastening airbag. Due to the separable design of the annular wall, before the tube is inserted, the limiting piece and the connector can be temporarily connected by the temporary snap-fit ​​between the annular wall and the embedding groove, avoiding the problem of forgetting to install the limiting piece after tube insertion or the limiting piece slipping inward during tube insertion.

[0016] Preferably, a stop ring is connected to the outer periphery of the connector. The stop ring fixed on the connector forms a further limiting structure at the end of the tube that is located on the outside, so as to limit the position of the tube even in the worst case (when the limiting structure is not properly installed and the tube slides inward), thereby further improving the safety of the patient.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] like Figures 1 to 4 The endotracheal tube shown includes a tube body 1, a limiting piece 2, and a deformable component.

[0024] One end of the tube body 1 is provided with a connector 3, and the other end of the tube body 1 is provided with an air outlet and a fixing airbag 10, and the fixing airbag 10 is connected to an inflation connector 12 through a branch tube 11. In this embodiment, the connector 3 is a standard connector at the beginning of an existing endotracheal tube.

[0025] The limiting piece 2 has a through hole 20 in the middle. The limiting piece 2 can be sleeved on the tube body 1 near the connector 3, and the limiting piece 2 and the tube body 1 can be detachably connected. The inside of the through hole 20 is tightly wrapped with the endotracheal tube by the fastening component 4. In this embodiment, the surface or edge structure of the limiting piece 2 is made of an elastic material (such as elastic silicone or elastic rubber) to avoid excessive pressure.

[0026] Regarding the detachable connection method of the limiting piece 2, it can be that the inner diameter of the perforation 20 is much larger than the outer diameter of the tube body 1, allowing the limiting piece 2 to be directly fitted onto the tube body 1 and connected and locked in conjunction with the fastening component 4; alternatively, the limiting piece 2 can adopt an elastic sheet structure, with an opening on one side communicating with the perforation 20, which can be opened and snapped onto the tube body 1. In this embodiment, the limiting piece 2 is used in a way that allows it to be directly fitted onto the tube body 1 and connected and locked in conjunction with the fastening component 4.

[0027] The fastening assembly 4 includes an annular wall 40, a fastening airbag 41, an inflation connector 42, and a delivery pipe 43. The annular wall 40 is fixedly located at the perforation 20, the fastening airbag 41 is arranged around the inner side of the annular wall 40, and the fastening airbag 41 is connected to the inflation connector 42 through the delivery pipe 43.

[0028] To increase the connection stability and blocking effect of the limiting piece 2, the fastening assembly 4 also includes an adhesive layer 44, which is disposed on the surface of the fastening airbag 41, and the adhesive layer 44 is made of an anti-slip material (such as a thin layer of rubber or a thin layer of silicone) or has multiple anti-slip particles.

[0029] To avoid excessive pressure on the mouth area, the annular wall 40 is located away from the end of the connector 3 and does not extend beyond the end face of the limiting piece 2 facing the side where the fixed airbag 10 is located.

[0030] The connector 3 has an embedding groove 6 on the side facing the limiting piece 2, and the embedding groove 6 is adapted to the annular wall 40 and the fastening airbag 41, which allows the annular wall 40 of the limiting piece 2 to be embedded in it. This can prevent the patient from forgetting to put in the limiting piece 2 after the endotracheal tube has been inserted.

[0031] A deformable component is disposed on the tube body 1, and the deformable component is located on the inner side of the tube body 1 corresponding to the tooth. The deformable component can be a limiting airbag 5 disposed on the tube body 1 in this embodiment, or it can be a medical silicone component with an antibacterial layer on the outside, capable of being deformed appropriately to adapt to the shape of the oral cavity. In this embodiment, to facilitate subsequent removal operations, a limiting airbag 5 structure is adopted, and the limiting airbag 5 is connected to a transmission connector 51 via a transmission tube 50.

[0032] The limiting plate 2 has multiple grooves 21, which are evenly spaced along the outer periphery of the limiting plate 2. In this embodiment, the limiting plate 2 body and the grooves 21 together form a plum blossom-shaped structure. The aforementioned branch pipe 11, conveying pipe 43 and transmission pipe 50 can all pass through the grooves 21, and the corresponding connector structures are located on the outside. In addition, a stop ring 7 is connected to the outer periphery of the connector 3.

[0033] During use, the entire annular wall 40 is a complete ring. Before the tube body 1 is inserted, the limiting piece 2 is first placed on the tube wall of the tube body 1, and the position of the limiting piece 2 is adjusted so that the limiting piece 2 moves to a position close to the connector 3. Then, appropriate force is applied so that the annular wall 40 and the part of the fastening airbag 41 are inserted into the embedding groove 6 of the connector 3 to achieve a temporary connection between the limiting piece 2 and the connector 3.

[0034] Next, adjust the positions of branch tube 11, delivery tube 43, and transmission tube 50 so that these tubes are located in the groove 21 of the limiting piece 2, and position the filling connector 12, inflation connector 42, and transmission connector 51 close to the connector 3. After inserting the tube body 1 into the patient's body, the filling connector 12, inflation connector 42, and transmission connector 51 are located on the outside. Then, adjust the position of the limiting airbag 5 so that it is located between the inside of the teeth and the tongue (i.e., in the oral cavity), and pull the annular wall 40 of the limiting piece 2 out of the insertion groove 6 of the connector 3 so that the limiting piece 2 is located on the outside of the teeth. The fixing airbag 10, the fastening airbag 41, and the limiting airbag 5 are respectively inflated through the filling connector 12, the air inflator 42, and the transmission connector 51. The fixing airbag 10 is fixed at the tail end of the tube 1 inside the human body. The fastening airbag 41 is inflated to fill the gap between the annular wall 40 and the outer wall of the tube 1, and to make the adhesive layer 44 fit tightly against the outer wall of the tube 1, so as to achieve a stable connection between the limiting piece 2 and the tube 1. The limiting airbag 5 is fixed between the inside of the teeth and the tongue.

[0035] When the tube body 1 is displaced, if the tube body 1 is pulled outward by force, the limiting airbag 5 will be blocked by the inside of the teeth; if the tube body 1 is displaced inward by force, the limiting airbag 5 will be blocked by the tongue, and the limiting piece 2 will be blocked by the outside of the teeth.

[0036] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
