Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a dental pad. Background Art

[0002] At present, the main purpose of using dental pads in clinical anesthesia is to open the patient's mouth to avoid deformation of the tracheal tube, and at the same time to attract oral secretions.

[0003] Tracheal tubes are used to maintain airway patency, ensuring efficient oxygen delivery and suctioning oral secretions. Typically, a through-hole is provided in the bite block to serve as the endotracheal tube's access port. However, existing bite blocks lack the ability to securely connect to endotracheal tubes of varying sizes, and are unsuitable for patients undergoing neuroelectrophysiological monitoring during general anesthesia surgery. (These patients may experience severe facial muscle contraction, potentially damaging their teeth and oral soft tissues.) Utility Model Content

[0004] The purpose of the utility model is to provide a dental pad which can be used for neuroelectrophysiological monitoring and can be fixedly connected to tracheal tubes of different sizes.

[0005] In order to achieve the purpose of this utility model, the following technical solutions are adopted:

[0006] A mouthpiece, comprising a U-shaped mouthpiece body, wherein a first through-hole penetrating the inner and outer sides of the U-shaped mouthpiece body is provided near the bending position of the U-shaped mouthpiece body, the first through-hole being used for allowing an endotracheal tube to pass through, and a fixing mechanism being provided on the outer side of the U-shaped mouthpiece body at the position of the first through-hole, the fixing mechanism being used for fixed connection with the endotracheal tube.

[0007] A further improvement is that the thickness of the U-shaped tooth pad body gradually becomes thinner from the curved position to both sides.

[0008] A further improvement is that a U-shaped lip guard is formed on the U-shaped bite pad body and extends vertically upward along the outer edge of the U-shaped bite pad body.

[0009] A further improvement is that the fixing mechanism includes a hollow tube extending outward from the outer side of the U-shaped bite block body, the tube hole of the hollow tube is connected to the first through hole, the hollow tube body is provided with a notch running through the front and back of the tube body, the hollow tube body extends outward at the two edges of the notch to form connecting plates, and the two connecting plates are respectively provided with a through hole for cooperating with the rope to bind the tracheal tube in the hollow tube so that the tracheal tube and the bite block are fixedly connected.

[0010] A further improvement is that a second through hole is provided on one side of the first through hole and passes through the inner and outer sides of the U-shaped tooth pad body, and the second through hole is used for allowing the suction tube to pass through.

[0011] A further improvement is that the tooth pad is integrally formed.

[0012] The beneficial effects of the utility model are:

[0013] The bite block provided by the present invention can prevent deformation of the endotracheal tube, avoid damage to the patient's teeth during surgery, and prevent bites to the tongue and oral soft tissues. The present invention provides a first through-hole near the bending position of the U-shaped bite block body and a fixing mechanism at the position of the first through-hole on the outer side of the U-shaped bite block body. When in use, after the endotracheal tube passes through the first through-hole, the endotracheal tube can be fixed by the fixing mechanism, thereby achieving fixation between the endotracheal tube and the bite block.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0019] It should be noted that when an element is referred to as being "fixed on", "set on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intermediate element at the same time. Furthermore, when an element is considered to be "transmission-connected" to another element, it is sufficient that the two can achieve power transmission, and its specific implementation method can be implemented using existing technologies and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0022] Please refer to the attached Figure 1 , Attachment Figure 2 The present invention provides a bite block suitable for use with intubated patients under general anesthesia, and particularly suitable for use with patients undergoing neuroelectrophysiological monitoring under general anesthesia. Specifically, the bite block includes a U-shaped bite block body 1. A first through-hole 2 is provided near the bend of the U-shaped bite block body 1, extending through the inner and outer sides of the U-shaped bite block body 1. The first through-hole 2 is used to allow an endotracheal tube (not shown) to pass through. A fixing mechanism is provided on the outer side of the U-shaped bite block body 1 at the location of the first through-hole 2, and the fixing mechanism is used to securely connect with the endotracheal tube.

[0023] It can be understood that the design of the U-shaped bite pad body 1 can better adapt to the oral structure. The utility model provides a first through hole 2 near the bending position of the U-shaped bite pad body 1 and a fixing mechanism is provided on the outer side of the U-shaped bite pad body 1 at the position of the first through hole 2. When in use, after the tracheal tube passes through the first through hole 2, the tracheal tube can be fixed by the fixing mechanism, thereby achieving fixation between the tracheal tube and the bite pad.

[0024] In a preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, the thickness of the U-shaped bite block body 1 gradually becomes thinner from the bending position to both sides, that is, gradually becomes thinner from one end of the U-shaped bite block body 1 to the other end.

[0025] In a preferred solution of this embodiment, a U-shaped lip protection piece 3 is formed on the U-shaped bite block body 1 and extends vertically upward along the outer edge of the U-shaped bite block body 1 to protect the lips.

[0026] In a preferred solution of this embodiment, the fixing mechanism includes a hollow tube 4 extending outward from the outer surface of the U-shaped bite block body 1, the tube hole of the hollow tube 4 is connected to the first through hole 2, and the hollow tube 4 is provided with a notch running through the front and back of the tube body. The hollow tube 4 extends outward at the two edges of the notch to form connecting plates 5, and the two connecting plates 5 are respectively provided with a through hole 6, which is used to cooperate with a rope (not shown in the figure) to bind the tracheal tube in the hollow tube 4 so that the tracheal tube and the bite block are fixedly connected.

[0027] It is understandable that, when in use, after tying the tracheal tube with a string, the string is passed through the through hole 6 of the connecting plate 5 and tied tightly, so that the tracheal tube and the bite block are fixedly connected and cannot move relative to each other.

[0028] In addition, in other embodiments of the present invention, the fixing mechanism may also adopt an elastic buckle (not shown in the figure), which is fixedly installed on the outer side of the U-shaped bite block body 1 to clamp and fix the tracheal tube.

[0029] In a preferred solution of this embodiment, a second through hole 7 is provided on one side of the first through hole 2 and passes through the inner and outer sides of the U-shaped tooth pad body 1. The second through hole 7 is used for a sputum suction tube (not shown in the figure) to pass through.

[0030] In this embodiment, the dental pad is integrally formed and can be made of medical high-density polyethylene resin or silicone.

[0031] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which are protected by the present invention.
