AI Technical Summary
Existing endotracheal tubes can easily cause compression or damage to the patient's tongue during long-term intubation, and the fixation method is not stable enough.
An oral endotracheal tube comprising a lateral airbag and a silicone sheet was designed. The silicone sheet is deployed by the expansion of the lateral airbag, and the reaction force is used to fix the position of the tube, preventing the tongue from sliding and reducing the pressure on the tongue.
It effectively fixes the catheter position, preventing the tongue from sliding and getting injured, while reducing the discomfort of the patient biting the catheter and protecting the tongue from excessive pressure.

Abstract
Description
Technical Field
[0001] This invention relates to the field of medical technology, and more specifically, to an oral endotracheal tube. Background Technology
[0002] Currently, when using a conventional endotracheal tube for patients requiring invasive respiratory support, if long-term intubation is needed, an additional cylindrical bite block is required to secure the endotracheal tube. The tube and bite block are then tied together with thin cotton string to prevent slippage or accidental dislodgement. However, this method of fixation, the endotracheal tube, and the bite block itself can cause some degree of compression or damage to the patient's soft tongue.
[0003] Therefore, it is necessary to provide an oral endotracheal tube to solve the above problems. Utility Model Content
[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide an oral endotracheal tube to achieve the effect of protecting the tongue.
[0005] The technical solution adopted by this application to solve its technical problem is: an oral endotracheal tube, including a tube, a lateral airbag provided on one side of the tube, a second inflation port connected to the upper end of the lateral airbag, an annular silicone sheet sleeved on the tube, and the lateral airbag located inside the silicone sheet.
[0006] Furthermore, a first airbag is fixedly sleeved on the lower outer wall of the conduit, and a first inflation port is provided on one side of the upper end of the conduit. The first airbag is connected to the first inflation port pipe.
[0007] Furthermore, the conduit has a multi-layer structure, and the pipe connecting the first airbag and the first inflation port is located within the interlayer of the multi-layer structure of the conduit.
[0008] Furthermore, the silicone sheet has a two-lobed silicone thin-layer structure.
[0009] Furthermore, the outer wall of the catheter is provided with a tracer line.
[0010] Furthermore, an inner core is provided inside the catheter.
[0011] The beneficial effects of this utility model are:
[0012] The expansion of the lateral airbag after inflation pushes the silicone sheet outward, causing the silicone sheet to press against the patient's mouth. At this time, the silicone sheet will press against the patient's mouth outward, using the reaction force to fix the position of the catheter, preventing the tongue from sliding and eliminating the need for the patient to bite the catheter. At the same time, the flexible deformation of the lateral airbag and silicone sheet can prevent the tongue from being injured due to excessive pressure. Attached Figure Description

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0023] In this invention, unless otherwise stated, the orientations used, such as "up" and "down," generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this invention.
[0024] like Figure 1-3As shown, this application provides an oral endotracheal tube, including a tube 1, a first air bladder 11 fixedly sleeved on the lower outer wall of the tube 1, and a first inflation port 12 provided on one side of the upper end of the tube 1. The first air bladder 11 is connected to the first inflation port 12 via a pipe.
[0025] The conduit 1 has a multi-layer structure, and the pipe connecting the first airbag 11 and the first inflation port 12 is located in the interlayer of the multi-layer structure of the conduit 1.
[0026] A lateral airbag 2 is provided on one side of the conduit 1, and a second inflation port 21 is connected to the upper end of the conduit 2.
[0027] A ring-shaped silicone sheet 3 is fitted onto the catheter 1, and the lateral airbag 2 is located inside the silicone sheet 3. The silicone sheet 3 has a two-lobed silicone thin-layer structure.
[0028] It is understandable that the outer wall of catheter 1 is provided with a tracer line (not shown in the figure), and the inner core is provided inside catheter 1. Both the tracer line and the inner core are conventionally provided on the upper side of catheter 1.
[0029] Before use, the first airbag 11 and the side airbag 2 are in an uninflated state, and the inner core is inserted into the tube 1.
[0030] When using it, insert the lower end of catheter 1 into the patient's mouth, and have the nurse hold catheter 1, the lateral balloon 2 and the silicone sheet 3.
[0031] After the tracer wire passes through the glottis, the inner core is pulled out and air is injected into the first air bag 11 through the first air inlet 12 to fix the lower end of the tracheal tube and to close the gap of the glottis to the maximum extent.
[0032] After the first airbag 11 is inflated, air is introduced into the lateral airbag 2 through the second inflation port 21, causing the lateral airbag 2 to expand. As the lateral airbag 2 expands, it pushes the silicone sheet 3 outwards, causing the silicone sheet 3 to press against the patient's mouth. At this time, the silicone sheet 3 presses outwards against the patient's mouth, using the reaction force to fix the position of the catheter 1, preventing tongue slippage and eliminating the need for the patient to bite down on the catheter 1. Simultaneously, the flexible deformation of the lateral airbag 3 and the silicone sheet 3 prevents excessive pressure on the tongue, thus avoiding injury.
