Description

Technical Field

[0001] The present invention relates to the technical field related to anesthesiology, and in particular to a dental pad for anesthesiology. Background Art

[0002] During general anesthesia, a matching tooth pad is often required. Its main purpose is to prevent the patient from biting the endotracheal tube in the mouth and causing ventilation difficulties. It can also help fix the endotracheal tube, prevent the endotracheal tube from shifting in the mouth, assist in attracting oropharyngeal secretions, and assist in inserting the tube into the oropharynx or stomach. However, neuromonitoring may be used in neurosurgery, and there may be damage caused by contraction of the masseter muscle during neuromonitoring. The main reason is that transcranial motor evoked potential (TCMEPS) is the most commonly used technology in intraoperative neurophysiological monitoring. However, due to cranial electrical stimulation, the masseter muscle is contracted rigidly, causing the patient to bite the upper and lower teeth too hard in an unconscious state, resulting in the risk of tongue (common) or lip contusion or tear, tooth damage, and endotracheal tube rupture. Severe tongue hematoma may cause the risk of airway obstruction after endotracheal extubation. The bite caused by strong stimulation may cause the endotracheal tube to rupture, requiring emergency re-intubation. In order to solve this problem, a tooth pad is usually needed to assist. The main body of the common tooth pad is a rectangular structure that can be placed between the patient's upper and lower incisors after intubation to prevent the teeth from biting or even biting off the endotracheal tube. There are suction holes between the main bodies, which is convenient for us to perform sputum suction operations. In addition, the two sides of the main body are of different lengths, the long side is the tongue surface, and the short side is the jaw surface. The overly long tongue surface is similar to the role of a tongue guard. When used by patients who have not undergone tracheal intubation, it prevents the tongue from falling back to facilitate the tube delivery operation. However, in the actual operation process, since the current tooth pad body is made of high molecular weight polypropylene material, patients will still have the phenomenon of biting the tooth pad flat and blocking the tracheal intubation. The main reason is that the overall area of ​​the tooth pad is small and is only fixed between the patient's upper and lower incisors. Especially during neurosurgery, nerve monitoring is required during the operation, so muscle relaxants cannot be used. At the end of the operation, the patient may have the risk of loosening and falling off of the upper teeth. In severe cases, the teeth need to be extracted, which seriously affects the patient's chewing function and appearance. The main reason for this situation is that the masseter muscle cooperates with the temporalis muscle, medial pterygoid muscle and lateral pterygoid muscle to cause the patient's lower jaw to move forward and backward during this process, which damages the tooth pad and further aggravates the wear of the patient's incisors. Therefore, there is an urgent need for a dental pad for use in neurosurgery under general anesthesia, which can not only ensure tracheal intubation, but also effectively prevent tooth damage during the operation. Summary of the invention

[0003] The purpose of the present invention is to provide a dental pad for anesthesiology, which can effectively solve the problems existing in the background technology.

[0008] Due to the adoption of the above technical scheme, the present invention has the following beneficial effects: the structure is simple, and pads arranged along the gums are respectively provided at the upper and lower ends of the dental pad body, so that the pads can effectively increase the contact area of ​​the entire gums, reduce the vertical force of the dental pad on the front incisors, and also reduce the vertical pressure of the dental pad. The pads that bear pressure together use the inflatable airbag and the driving airbag to limit the forward and backward movement of the incisors, which not only avoids the loosening of the incisors in contact with the dental pad, but also avoids the blockage of the intubation tube caused by damage to the dental pad.

[0013] The driving airbag 8 is integrally sleeved on the pipe 3 , and both ends of the driving airbag 8 are pressed between the piston plate 11 and the adjacent cover plate 2 .

[0014] The middle part of the backing plate 5 is fixed on the tooth pad body 1 .

[0015] The outer side of the backing plate 5 is provided with a guard plate 14 which fits the side of the gums.

[0016] The following is a further description of the method and principle of using the technical solution in this specific implementation method in conjunction with the accompanying drawings: When in use, first place the dental pad body 1 in the patient's mouth, and insert the pad 5 into the patient's gums. At this time, the focus of oral occlusion is not only on the dental pad body 1, but is dispersed to the entire gums through the pad 5, reducing the force on the front incisors. At the same time, after the patient bites the pad 5 and the dental pad body 1, the gas in the compressed inflatable airbag 6 will enter the driving airbag 8 through the pad 5. Since the cover plate 2 is fixed to the end of the dental pad body 1, the driving airbag 8 drives the fixing plate 10 through the piston plate 11 during the extension process, and the front incisors are tightly fixed between the fixing plate 10 and the pad 5, thereby avoiding damage to the dental pad and damage to the incisors caused by the forward and backward movement of the lower jaw, and truly achieving all-round protection from the occlusal direction of the front incisors to the forward and backward movement direction of the upper and lower jaws.
