Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a mouthpiece for intubation. Background Technology

[0002] During anesthesia intubation, airway products (such as endotracheal tubes and oropharyngeal airways) are prone to displacement or being bitten, affecting ventilation and oxygen supply, leading to insufficient oxygenation, death, or postoperative complications. Common solutions include: 1. For endotracheal tube displacement, directly fixing it to the patient's face with tape. However, this carries the risk of tape detachment, allergic reactions, and does not address the issue of the airway product being bitten. 2. For damaged airway products, placing a bite block on the mouth for support does not solve the risk of displacement.

[0003] Patent CN114788737A discloses a biting aid and a biting device. The biting device is suitable for placement in a patient's mouth and for inserting multiple tubing tubes into the patient's mouth. The biting device includes a biting member and a biting aid having an outer fixing plate structure overlapping the biting member. The biting member includes a biting abutment, a through-sleeve portion protruding from the biting abutment, and a through-hole for inserting tubing. The outer fixing plate structure has a main auxiliary hole and at least one secondary auxiliary hole. However, this structure still has the problem of not being able to adapt to various sizes of tubing and needs improvement. Utility Model Content

Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] like Figures 1-4 As shown, the intubation mouthpiece provided in this embodiment is mainly composed of a support body 10, a mouthpiece body 20 disposed on one side of the support body 10, a fixing body 30 disposed on the other side of the support body 10, and an elastic band 40 disposed on the support body 10. The support body 10 is used to cover the human face to achieve support and coverage of the face, especially the mouth. The mouthpiece body 20 is for the human mouth to bite. The mouthpiece body 20 has an open channel 21 with a side opening for the intubation tube to pass through. That is, the open channel 21 is generally U-shaped. The fixing body 30 is provided with an opening 301 for the intubation tube to pass through. The opening 301 is connected to the open channel 21. The inner diameter of the opening 301 is adjustable and holds and fixes the intubation tube. It is stabilized by the elastic band 40 surrounding the human head.

[0028] The fixed body 30 includes a connecting part 31 and a holding part 32. The connecting part 31 is protruding on the other side of the supporting body 10, and the holding part 32 is detachably mounted on the connecting part 31.

[0029] Furthermore, the holding part 32 includes a connecting plate 321, on which a holding ring 322 and a limiting body 323 are provided. An opening 301 is formed in the holding ring 322, and there is a gap between the holding ring 322 and the limiting body 323. An axially penetrating notch 3221 is provided on one side of the holding ring 322. Multiple teeth 3222 are protruding on one side of the notch 3221 to form an adjustment end. The adjustment end can be inserted into the gap between the holding ring 322 and the limiting body 323. The limiting body 323 is used to engage with any one of the teeth 3222, that is, to perform insertion adjustment at the side position.

[0030] Here, the limiting body 323 is roughly in the shape of a figure 7, with one of its lateral ends facing the adjustment end, thereby achieving a snap-fit ​​with the tooth body 3222, thus stably holding the insertion tubes of different outer diameters.

[0031] Correspondingly, a protruding plate 3241 is provided on the outer side of the clamping ring 322, and a protruding plate 3242 is provided on the side of the limiting body 323 opposite to the clamping ring 322. The protruding plate 3241 and the protruding plate 3242 are provided for the human hand to hold, so that force can be applied to deform the limiting body 323 and the clamping ring 322, and the size of the opening 301 can be adjusted to adapt to different insertion tubes.

[0032] The connecting part 31 is provided with a receiving groove, which generally forms a U-shaped structure, and the connecting plate 321 is inserted into the receiving groove for connection.

[0033] The support body 10 has an opening 301 in the middle, and the position of the opening 301 corresponds to the position of the holding part 32. A secondary hole 101 is provided on each side of the opening 301 for use.

[0034] Additionally, each side of the support body 10 is provided with a through hole 11, and a fixing hole 12 is provided on one side of each through hole 11. The through hole 11 is for the elastic band 40 to pass through, and the fixing hole 12 is provided with a protruding tooth 13 for engaging with the elastic band 40. That is, one end of the elastic band 40 is fixed in one through hole 11, and the other end is wrapped around the back of the human head, passes through another through hole 11, and enters the fixing hole 12 for engagement and fixation. The elastic band 40 is placed on the human head, so the elastic band 40 can be adjusted and tightened according to the size of the human head.

[0035] All descriptions herein may be presented in any suitable order.
