Description

Technical Field

[0001] This utility model relates to the field of medical endotracheal intubation auxiliary tools, specifically an anti-bite device for endotracheal intubation. Background Technology

[0002] An endotracheal tube is a medical device inserted into a patient's trachea and / or bronchi to create a temporary artificial breathing channel, especially for patients unable to breathe independently. In major hospitals, endotracheal tubes are among the most important tools used by doctors, coming into contact with them almost daily. They provide a breathing pathway between the patient's lungs and the anesthesia breathing circuit, and are crucial for the patient's perioperative safety. Suctionable endotracheal tubes are designed for the effective management of airway secretions. The opening above the balloon allows for efficient suctioning of secretions without repositioning the tube. The yellow suction tube and connector are easily identifiable, and the cap on the suction tube closes tightly when not suctioning, preventing contaminants from entering the lumen. They are suitable for extended surgeries and ICU-assisted suctioning.

[0003] Common endotracheal tubes have one or two cuffs at the tip. When inflated, the cuffs secure the tube and seal the airway. They may also be used without cuffs. The tube body is usually made of polymer material with an embedded steel wire coil to improve radial strength and axial flexibility. Some tube bodies are made of laser-resistant materials or are multilayered to protect against laser radiation. They are inserted into the patient's trachea via the nose / mouth or percutaneously. One end connects to an anesthesia ventilator via a breathing circuit to maintain the patient's respiration. They are provided sterile and are for single use only.

[0004] Endotracheal tubes are widely used in patients after general anesthesia, patients unable to breathe spontaneously, patients with poor lung function, and patients requiring mechanical ventilation. However, in clinical use, some agitated patients, or those who are intentionally or unintentionally biting or tearing the trachea, cuff, or inflation line, require a complete endotracheal intubation. Therefore, at least the following problems still exist in this area:

[0005] 1. To prevent patients from biting or rupturing any of the trachea, cuff, or inflation line, medical staff routinely attach a bite pad / mouth pad / mouth plug next to the trachea to support the patient's teeth and prevent biting the trachea. While this does prevent patients from biting the trachea to some extent, the bite pad / mouth pad / mouth plug can easily injure the patient's lips and tongue, causing instrumental damage to the patient's oral cavity.

[0006] 2. Existing mouth pads, being made of hard plastic, can still cause damage to the patient's lips and oral cavity if used for an extended period of time;

[0007] 3. There are many styles of existing endotracheal tubes, and they come in different sizes and thicknesses, while existing mouth pads cannot be used interchangeably for different sizes and models;

[0008] 4. In use, existing mouth pads require the use of tape to stick them around the patient's mouth. Over time, the tape sticking to the skin makes it difficult for the skin to breathe, and it also affects the patient's speech. In addition, when the tape is removed, it can tear the patient's skin and cause pain.

[0009] 5. When using existing mouthguards, if other oral examinations or suctioning procedures are required, the patient's mouth is closed, making it impossible to perform these procedures. Utility Model Content

[0010] The purpose of this invention is to at least solve the problems of current mouth pads being incompatible with endotracheal tubes of different diameters and causing pressure injuries to the mouth.

[0011] To solve the above-mentioned technical problems, the present invention provides an anti-biting device for endotracheal intubation, comprising:

[0012] First main pad,

[0014] The mounting frame has mounting positions extending through its front and rear sides; the first main pad and the second main pad are detachably installed within the mounting positions.

[0015] A flexible pad is mounted around the mounting frame and is detachably connected to the mounting frame.

[0016] As a preferred embodiment of the anti-biting device for endotracheal intubation of this utility model, the first main pad and the second main pad respectively have a communicating first positioning groove;

[0017] The side of the mounting frame has a second positioning slot; the first positioning slot corresponds to the second positioning slot;

[0018] It includes a positioning insert that passes through the second positioning slot and is at least partially located within the first positioning slot.

[0019] As a preferred embodiment of the endotracheal intubation anti-bite device of this utility model, the side of the first main pad that abuts against the second main pad has a fixedly connected positioning component;

[0020] The side of the second main pad that abuts against the first main pad has a positioning hole; when the first main pad abuts against the second main pad, the positioning element is located in the positioning hole.

[0021] As a preferred embodiment of the endotracheal intubation anti-bite device of this utility model, the main mounting frame has a strap connection position; including a strap, the strap and the strap connection position are detachably connected.

[0024] In a preferred embodiment of the endotracheal intubation anti-bite device of this utility model, the flexible pad has a limiting groove, and the anti-dislodgement edge is at least partially located within the limiting groove.

[0025] As a preferred embodiment of the endotracheal intubation anti-bite device of this utility model, it includes a flexible sleeve, and the portions of the first main pad and the second main pad passing through the mounting position are located inside the flexible sleeve.

[0026] As a preferred embodiment of the endotracheal intubation anti-bite device of this utility model, the first main pad and the second main pad have a concave area on the side that passes through the mounting position;

[0027] The flexible sleeve has an inwardly folded skirt at one end corresponding to the concave area. The inwardly folded skirt is at least partially located in the concave area and at least partially wraps around the edges of the first main pad and the second main pad.

[0047] In the accompanying drawings, the same reference numerals represent the same parts. It should be noted that the described embodiments are only some, not all, of the embodiments disclosed herein.

[0048] Based on the embodiments described in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure.

[0049] This utility model relates to an anti-bite device for endotracheal intubation. See [link / reference]. Figures 1 to 9 Includes: First main pad 1, Second main pad 2, Figure 6 The first main pad 1 and the second main pad 2 are shown to each have at least one first conduit mounting groove 3 and at least one second conduit mounting groove 4. The cross-sections of the first conduit mounting groove 3 and the second conduit mounting groove 4 are semi-circular or arc-shaped. The radius of the second conduit mounting groove 4 is smaller than the radius of the first conduit mounting groove 3. Figure 1 and Figure 5This demonstrates that when the first main pad 1 and the second main pad 2 are assembled, the first conduit mounting groove 3 of the first main pad 1 and the first conduit mounting groove 3 of the second main pad 2 are on the same axis and interconnected, and the second conduit mounting groove 4 of the first main pad 1 and the second conduit mounting groove 4 of the second main pad 2 are on the same axis and interconnected; as shown. Figure 5 As shown, the first conduit mounting groove 3 of the first main pad 1 and the second conduit mounting groove 4 of the second main pad 2 are combined to form the first conduit hole 5, and the second conduit mounting groove 4 of the first main pad 1 and the second conduit mounting groove 4 of the second main pad 2 are combined to form the second conduit hole 6.

[0050] Install main frame 7, as follows Figure 7 As shown, the mounting frame 7 has mounting positions 8 extending through its front and rear sides; the first main pad 1 and the second main pad 2 are detachably installed in the mounting positions 8; Figure 2 The diagram shows the effect of removing the first main pad 1 and the second main pad 2 from the mounting position 8. Figure 1 The image shows the effect of the first main pad 1 and the second main pad 2 being installed in the mounting holes 8 of the mounting frame 7;

[0051] Flexible pad 9, Figure 8 A 3D rendering of the flexible pad 9 is shown. Figure 5 The flexible pad 9 is shown to be mounted around the mounting frame 7, and the flexible pad 9 is detachably connected to the mounting frame 7.

[0052] Furthermore, among them Figure 4 and Figure 6 The surfaces of the first main pad 1 and the second main pad 2 are also provided with horizontal textures to facilitate the patient's biting on the first main pad 1 and the second main pad 2 during use.

[0053] This utility model of an anti-bite device for endotracheal intubation, through the cooperation of a first main pad 1 and a second main pad 2, utilizes a first catheter mounting groove 3 and a second catheter mounting groove 4 respectively set in the first main pad 1 and the second main pad 2 to form a first catheter hole 5 and a second catheter hole 6. On the one hand, it facilitates the installation of endotracheal tubes, and on the other hand, it allows medical workers to replace the first main pad 1 and the second main pad 2 with different diameters of first catheter hole 5 and second catheter hole 6 according to endotracheal tubes of different thicknesses, thus solving the problem that current mouth pads cannot be used with endotracheal tubes of different diameters.

[0054] And as Figure 1 As shown, this utility model has multiple first catheter holes 5 and second catheter holes 6. In use, extra through holes can be left, which not only facilitates the patient's breathing, but also solves the problem that existing mouth pads cannot be used to perform other examinations or suctioning operations in the oral cavity.

Figure 3 and Figure 4 The illustration shows the effect of the flexible sleeve 19 being installed on the first main pad 1 and the second main pad 2. Furthermore, the flexible sleeve 19 can be installed independently on the surface of the first main pad 1 and the second main pad 2, and the flexible sleeve 19 can also be fixedly connected to the flexible pad 9. This utility model of an anti-biting device for endotracheal intubation solves the problem of current mouth pads easily injuring the patient's lips and tongue, leading to instrumental damage to the patient's oral cavity, by adding the flexible sleeve 19.

[0067] Further, see Figure 4 The first main pad 1 and the second main pad 2 have a recessed area 20 on one side of the mounting position 8;

[0068] The flexible sleeve 19 has an inwardly folded skirt 21 at one end corresponding to the concave area 20. This inwardly folded skirt 21 is at least partially located in the concave area 20 and at least partially wraps around the edges of the first main pad 1 and the second main pad 2. This utility model's endotracheal intubation anti-bite device, through the inwardly folded skirt 21 provided on the flexible sleeve 19, achieves a tighter wrapping of the first main pad 1 and the second pad 2; on the other hand, it also avoids or reduces contact between the patient's tongue and the first main pad 1 and the second main pad 2.
