Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a tracheal intubation anti-bite tube device. Background Art

[0002] The endotracheal tube bite pad is fixed on the teeth of the oral cavity together with the endotracheal tube catheter. Endotracheal tube is a method of inserting a catheter into the trachea or bronchus to provide oxygen and promote the patency of the airway, and the purpose of the bite pad is to prevent the patient from biting the catheter. The catheter is placed in the center of the mouth, and the bite pad is placed between the upper and lower molars, and the catheter and the bite pad are fixed with tape. Existing endotracheal tube bite pads and catheters are mostly separate and have no connectivity with each other. For example, the oral intubation multifunctional fixing device disclosed in patent publication number CN217645648U includes an intubation fixing block and fixing belts arranged at both ends of the intubation fixing block, which are used to fix the pipeline during oral intubation and can fix multiple pipelines at the same time. Although this fixing device and the existing dental pad can fix the tube, the following technical problems still exist: when oral cleaning is required, medical staff need to remove the dental pad and clean the mouth on the catheter side; during the cleaning process, the catheter is still easy to be bitten, affecting the patient's ventilation and breathing, and to ensure that the mouth is clean, the catheter needs to be moved to clean the other side of the mouth, which is extremely inconvenient when moving the catheter. Utility Model Content

[0003] The utility model provides a tracheal intubation tube-biting prevention device which is flexible to use and can prevent the tube from being bitten during oral cleaning.

[0004] In order to achieve the above purpose, the technical solution of the utility model is:

[0005] A tracheal intubation anti-bite tube device includes a strip-shaped fixed plate, a connecting rod slidably connected to the fixed plate, and an annular sleeve connecting the connecting rod. The upper surface of the fixed plate is provided with a groove along the horizontal direction, and corresponding to the position of the groove, the upper and lower surfaces of the fixed plate are provided with blocking strips extending toward each other. The inner side of the upper end of the connecting rod is connected to a slider through a horizontal sliding rod, and the lower end of the connecting rod is inclined toward the side deviating from the fixed plate and fixedly connected to the outside of the annular wall of the annular sleeve, and the annular mouth of the annular sleeve is arranged toward the fixed plate.

[0006] Preferably, a soft silicone pad is bonded to the inner side of the fixing plate.

[0007] Preferably, the thickness of the soft silicone pad is 1-3 mm.

[0008] Preferably, a sunken shallow groove is provided on the surface of the fixing plate at an upper position avoiding the groove, and anti-slip grooves are provided in the shallow groove.

[0009] Preferably, the angle between the connecting rod and the section at the connection position of the annular sleeve is 120-140°.

[0010] Preferably, the length of the annular sleeve is 20-45 mm.

[0011] Preferably, the fixing plate, connecting rod and annular sleeve are all made of medical plastic material.

[0012] Preferably, the fixing plate is an arc-shaped strip structure adapted to the shape above the upper lip of the human body.

[0013] Preferably, a C-shaped clamping piece is provided on one side of the annular sleeve.

[0014] The above technical solution of the utility model has the following beneficial effects:

[0015] This new endotracheal tube bite prevention device is bonded to a fixed plate above the upper lip, and features a slidable annular sleeve that fits over the endotracheal tube. This ensures proper ventilation of the tube while the patient removes the bite block for oral hygiene, preventing the tube from biting. The device is used in conjunction with a bite block and is secured directly to one side of the block with a strap. The C-shaped connector also clips directly onto the block, resulting in a simple overall structure, ease of use, and high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 2 This is a side structural sectional view of the endotracheal tube bite prevention device of the utility model. DETAILED DESCRIPTION

[0018] The following describes the implementation of the present invention in detail with reference to the accompanying drawings and examples.

[0019] See also Figure 1-2 As shown, the utility model of the endotracheal tube anti-bite tube device includes a fixed plate 1 with a strip structure, a connecting rod 2 slidably connected to the fixed plate 1, and an annular sleeve 3 connecting the connecting rod 2. The upper surface of the fixed plate 1 is provided with a groove 4 along the horizontal direction, and the upper and lower surfaces of the fixed plate 1 corresponding to the position of the groove 4 are provided with a blocking bar 5 extending toward each other. The inner side of the upper end of the connecting rod 2 is connected to a slider 7 through a horizontal sliding rod 6. The lower end of the connecting rod 2 is inclined toward the side deviating from the fixed plate 1 and fixedly connected to the outside of the annular wall of the annular sleeve 3, and the annular mouth of the annular sleeve 3 is arranged toward the fixed plate 1; the annular sleeve wraps the endotracheal tube as a whole, and when in use, the teeth directly bite the annular sleeve to prevent the endotracheal tube from being bitten.

[0020] The inner side of the fixing plate 1 is bonded with a soft silicone pad 8, which can prevent the fixing plate from directly contacting the human skin and causing discomfort. In addition, the soft silicone material is more adherent to the skin. The thickness of the soft silicone pad 8 is 1-3 mm.

[0021] A sunken shallow groove 11 is provided on the surface of the fixing plate 1 at an upper position avoiding the groove 4. The shallow groove 11 is provided with anti-slip grooves. When in use, the strap is directly fixed on the shallow groove. The shallow groove and anti-slip setting can make the strap more firmly fixed.

[0022] The angle between the connecting rod 2 and the section at the connection position of the annular sleeve 3 is 120-140 degrees, which allows the oral cannula to transition naturally when the human body lies down. The length of the annular sleeve 3 is 20-45 mm.

[0023] The fixing plate 1 , the connecting rod 2 and the annular sleeve 3 are all made of medical plastic material.

[0024] In order to better fix the fixing plate above the upper lip, the fixing plate 1 is an arc-shaped strip structure that matches the shape of the upper lip of the human body. In order to facilitate biting, a recessed portion can be provided on the annular sleeve 3 corresponding to the position of the teeth.

[0025] In addition, a C-shaped clamping piece 14 may be provided on one side of the annular sleeve 3 , and the C-shaped clamping piece 14 may be directly clamped on the side tooth pad tube.

[0026] When the device of the utility model is used, the fixing plate is placed at the position below the upper lip and the nose, and can be fixed by bonding or binding with a band. At this time, the annular sleeve is placed on one side of the dental pad, and the human teeth bite the annular sleeve at the same time, and the endotracheal tube can be inserted. When the dental pad needs to be removed to clean the oral cavity, the slider on the movable connecting rod can slide to move the endotracheal tube, so that all parts of the oral cavity can be cleaned.

[0027] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
