Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to an anti-falling device and an anti-falling method suitable for various types of loose teeth during anesthesia or sedation. Background Art

[0002] For medical workers, it is very common and difficult for patients who are in the process of anesthesia or sedation to have loose teeth. During the whole process of anesthesia or sedation, it is often necessary to insert, retain and remove ventilation or suction devices to ensure the safety of the patient's airway, such as endotracheal intubation, laryngeal mask or oral suction, etc. These operations may cause loose teeth to fall out. At this time, the patient is in a state of being unable to cooperate, and there is a risk that the fallen teeth will enter the airway or esophagus and cause foreign body obstruction, or the fallen teeth will be incarcerated in the posterior pharyngeal wall and other locations.

[0003] Currently, the method of binding wires is often used clinically to fix loose teeth. This involves placing a silk thread around the root of the tooth and tying a knot. The end of the thread is then fixed around the mouth with tape. However, this method has the following problems: (1) For teeth where the root is thicker than the tip, the thread knot may not be fixed; for those that can be fixed initially, the wire may fall off during application, resulting in a high failure rate; (2) When the wire needs to be removed, a blade or scissors is often required, which can easily cause damage to the periodontal soft tissue.

10. A method for preventing various types of loose teeth from falling out during anesthesia or sedation, characterized in that: The method comprises the following steps: Step 1. Make a self-made anti-falling device according to the situation of loose teeth, the anti-falling device includes a mesh elastic bag, at least one fixing line, a locking buckle and an adhesive strip; wherein, one end of the mesh elastic bag is closed and the other end is open, and the open end of the mesh elastic bag is provided with at least one elastic fixing band; the fixing line passes through the wire hole at the neck of the mesh elastic bag to form at least one annular coil, and the annular coil is used to fix the loose tooth and / or fix the loose tooth and at least one adjacent tooth at the same time; after the fixing line is wound into an annular coil, both ends are installed in the locking buckle; the locking buckle is arranged on the outside of the mesh elastic bag, and is used to lock the fixing line, and unlock it by pressing the locking buckle; the adhesive strip is arranged on the inside of the elastic fixing band; Step 2. Before use, the fixing wire is in a stretched state, and then selectively wrapped around the loose tooth itself and / or the loose tooth and adjacent teeth; When the loose tooth has a normal shape and the size of the gap between the teeth adjacent to the left and right sides allows the fixing wire to pass through, four fixing wires are used, and the first annular coil formed by the first fixing wire is used to fix the loose tooth; the second annular coil formed by the second fixing wire simultaneously fixes the loose tooth and the left tooth adjacent to the loose tooth; the third annular coil formed by the third fixing wire simultaneously fixes the loose tooth and the right tooth adjacent to the loose tooth; the fourth annular coil formed by the fourth fixing wire simultaneously fixes the loose tooth and the left and right teeth adjacent to the loose tooth; When the loose tooth is an isolated tooth, a fixation wire is used to directly fix the loose tooth itself; When the root of one side of the loose tooth is sloped and may cause the fixing wire to fall off, fix the loose tooth and the teeth adjacent to the sloped side of the loose tooth at the same time, and fix the loose tooth and the teeth adjacent to the loose tooth on the left and right at the same time; do not fix the loose tooth directly, nor fix the loose tooth and the teeth adjacent to the sloped side away from the loose tooth at the same time; When there are adjacent teeth on only one side of the loose tooth, fix the loose tooth first, and then fix the loose tooth and the teeth adjacent to the loose tooth at the same time; then choose whether to fix the loose tooth and the teeth on the left and right sides adjacent to the loose tooth at the same time according to the position of the tooth on the missing side; if the distance between the position of the tooth on the missing side and the loose tooth is greater than 2 cm, do not fix it; otherwise, fix the loose tooth and the teeth on the left and right sides adjacent to the loose tooth; When the loose teeth are two or three adjacent teeth, fix them in the same way as above; When the loose teeth are more than three adjacent teeth or appear in at least two places, two or more anti-loosening devices are selected and fixed in the above-mentioned fixing method; Step 3. After the annular coils formed by the fixing wire are respectively inserted into different tooth gaps, the fixing wire is tightened and the fixing wire is tightened by a lock buckle; Step 4. Tear off the smooth hard paper of the adhesive strip and selectively stick the sticky side inside or outside the mouth near the loose tooth to achieve double fixation; Step 5. Place the fixing wire on the front side of the lock on the side of the face close to the loose tooth to complete the fixation of the loose tooth.
