Description

Technical Field

[0001] This utility model relates to the technical field of tracheal tube fixation devices, specifically an intraoral irregular-shaped inflatable cuff tracheal tube fixation device. Background Technology

[0002] Currently, during endotracheal intubation or laryngeal mask airway general anesthesia, the tube or laryngeal mask is usually fixed to the skin around the mouth by wrapping it together with a bite block with adhesive tape, or by tying it behind the neck with a strap. Both of these methods of fixing the endotracheal tube are achieved through external fixation and are the main methods of fixing the endotracheal tube.

[0003] For cases involving forehead or facial surgery or skin damage to the head and face, neither of the above two fixation methods can be implemented. Usually, surgical sutures are used to suture the endotracheal tube to the lips or oral tissue, which may cause minor tissue damage at the suture site. Alternatively, the oral cavity can be packed with gauze to fix the tube by squeezing, which is cumbersome and carries the risk of foreign objects such as gauze entering the esophagus or trachea. Utility Model Content

[0004] The purpose of this invention is to provide an intraoral irregular-shaped inflatable cuff tracheal tube fixation device to solve the problems mentioned in the background art, which usually require surgical sutures to be sewn onto the lips or oral tissue to fix the tracheal tube, causing minor tissue damage at the suture site; or using gauze to pack the oral cavity and fix the tube by compression, which is cumbersome and carries the risk of foreign objects such as gauze accidentally entering the esophagus or trachea.

[0005] This utility model discloses an intraoral irregular-shaped inflatable cuff tracheal tube fixing device, including a main connector, a connecting head, and a tracheal tube body. The tracheal tube body has a central axis portion on its exterior, with a gap groove formed at the center of the central axis portion. A retaining spring is fitted on the inner wall of the gap groove, and a retaining plate is connected to one end of the retaining spring. A protective pad is fixed on the inner wall of the retaining plate. A cuff is connected to the exterior of the central axis portion, and an adhesive layer is fixed between the cuff and the central axis portion. An installation piece is installed on the front end face of the central axis portion, and a gap groove is formed on the front end face of the cuff. A channel groove is opened on the side of the cuff, and an air inlet is installed on the left side of the top of the cuff.

[0006] This utility model discloses an intraoral irregular-shaped inflatable endotracheal tube fixing device, wherein the clamping plates are distributed in three groups in a ring around the center of the gap groove, and the clamping plates and the protective pad are bonded together.

[0007] This utility model relates to a device for fixing an intraoral irregularly shaped inflatable balloon tracheal tube, wherein three sets of retaining rings are evenly distributed on the end face of the retaining plate.

[0008] This utility model discloses an intraoral irregular-shaped inflatable cuff tracheal tube fixing device, wherein one end of the air inlet is connected to an air guiding hose, and the tail end of the air guiding hose is connected to an inflation / deflation device, which includes a one-way valve and a syringe. A common syringe can be used to increase or decrease the inflation volume and inflation pressure of the cuff.

[0009] This invention features a slot formed at the center of the central shaft, allowing the endotracheal tube body to pass through. During assembly, the central shaft surrounds the endotracheal tube body. Under the elastic compression of the retaining spring, a clamping plate holds the endotracheal tube body in place, allowing adjustment of the cuff's position. The cuff is then locked in place using an mounting plate. Inflating the cuff with an air-filling syringe gradually expands it, thus securing the endotracheal tube body inside the mouth without causing any tissue damage, eliminating the need for tape, and providing a secure, stable, and safe solution.

Detailed Implementation

[0014] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0015] Example

[0016] like Figures 1-2As shown, the present invention discloses an intraoral irregularly shaped inflatable cuff tracheal tube fixing device, comprising a main connector 1, a connecting head 2, and a tracheal tube body 3. The tracheal tube body 3 has a central axis portion 10 on its exterior, a gap groove 9 formed at the center of the central axis portion 10, a retaining spring 11 fitted on the inner wall of the gap groove 9, a retaining plate 12 connected to one end of the retaining spring 11, a protective pad 13 fixed on the inner wall of the retaining plate 12, a cuff 4 connected to the exterior of the central axis portion 10, an adhesive layer 16 fixed between the cuff 4 and the central axis portion 10, an mounting plate 15 installed on the front end face of the central axis portion 10, a gap groove 14 formed on the front end face of the cuff 4, a channel groove 5 for facilitating the suction of oral secretions opened on the side of the cuff 4, and an air inlet 6 installed on the left side of the top of the cuff 4.

[0017] The card plate 12 is distributed in three groups in a ring around the center of the gap groove 9, and the card plate 12 and the protective pad 13 form an adhesive connection.

[0018] Three sets of snap rings 11 are evenly distributed on the end face of the snap plate 12.

[0019] One end of the air inlet 6 is connected to an air guide hose 8, and the other end of the air guide hose 8 is connected to an air inflation syringe 7.

[0020] Further, when using it, it is necessary to first perform a three-dimensional model of the oral cavity to obtain a cuff 4 that fits the oral cavity, so that after the cuff 4 is inflated, it will fill the oral cavity space, play a role in fixing the endotracheal tube, and at the same time, it will not cause any tissue damage.

[0021] After the end of the further air-conducting hose 8 is connected to an air-inflating syringe, the air-inflating work is completed using the air-inflating syringe.

[0022] Furthermore, the capsule 4 is designed in an irregular shape, which is based on the anatomical structure of the oral cavity and formed by 3D modeling. After inflation, it will fill the space in the oral cavity and play a role in fixation. Due to its irregular shape, it will not fall off.

[0023] Working principle: First, the central shaft 10 is placed around the outside of the endotracheal tube body 3. Under the elastic compression of the retaining spring 11, the retaining plate 12 can be used to clamp the outside of the endotracheal tube body 3, thereby adjusting the position of the cuff 4. Then, the position can be locked by using the mounting plate 15. When the inflation syringe is pulled out, air is delivered and inflated using the inflation syringe. The cuff 4 gradually expands and inflates. Therefore, by filling with air, the endotracheal tube body 3 is fixed in the oral cavity, thus achieving the purpose of fixation.

[0024] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
