Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a dental pad for intubation protection. Background Art

[0002] With the rapid development of emergency technology, the requirements for the integration of various equipment needed to rescue critically ill patients are becoming increasingly higher. Tracheal intubation is an important measure to rescue critically ill patients. Tracheal intubation refers to the insertion of a special tracheal tube into the patient's trachea through the mouth or nose. It is a technology for intratracheal anesthesia and rescue of patients. It is also the most reliable means of maintaining upper respiratory tract patency. It is mainly used in clinical emergency resuscitation, rescue of respiratory muscle paralysis, surgical anesthesia, open airway and other medical technologies.

[0003] The mouthpiece is designed to prevent the patient's teeth from wearing out the endotracheal tube and to attract oral secretions.

[0004] A Chinese utility model patent with authorization announcement number CN217772951U discloses a soft bite block for endotracheal intubation. The bite block includes a tracheal insertion hole device for holding the endotracheal tube on the side wall of the bite block body. This device clamps the endotracheal tube and connects the bite block to the endotracheal tube for fixation, improving the stability of the tube and the bite block. Furthermore, the bite block is provided with an oral airbag whose size can be adjusted according to the size of the patient's mouth, allowing the bite block to better fit the patient's oral cavity and gums, making the wearing experience more comfortable. However, during surgery, neuroelectrophysiological motor evoked potential monitoring will cause muscle contraction throughout the body, making it easy for the patient to stick their tongue between the bite block body and their teeth, causing tongue bite injuries.

[0005] Therefore, the present application provides a dental pad for intubation protection to solve the above problems. Utility Model Content

[0006] The present application provides a dental pad for intubation protection, aiming to solve the problem proposed in the background art that the existing dental pad body can only protect the intubation part, leaving a gap between the two sides of the dental pad body and the teeth, and the tongue in the gap will be bitten during the patient's biting process.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a dental pad for intubation protection, comprising a protective pad relatively arranged between the upper and lower jaws for protecting the intubation and an arc-shaped groove opened between the two protective pads for the insertion of the intubation; during the use of the intubation, the two protective pads clamped on the outside of the intubation can prevent the intubation from being bitten or broken, thereby ensuring the safety of the intubation during use.

[0008] To prevent the tongue from being bitten by the teeth due to muscle contraction, the device also includes a bite block body fixedly connected to opposite ends of the two protective pads for the upper and lower jaws to bite together. When the upper and lower teeth bite the protective pads, the bite block body can block the tongue inside the upper and lower teeth, preventing the tongue from being caught between the upper and lower teeth and causing bite injuries.

[0009] Preferably, to improve the applicability of the protective pad, an installation gap communicating with the arcuate groove is provided between the two protective pads. When used on different patients, the installation gap between the two protective pads allows for a certain degree of misalignment of the two protective pads without affecting the installation of the cannula, thereby making the bite block suitable for different patients and improving the applicability of the bite block.

[0010] Preferably, to facilitate installation of the bite block body, the top and bottom ends of the bite block body are provided with tooth grooves corresponding to the teeth. During installation of the bite block body, the tooth grooves can be used to position the bite block body, thereby preventing the teeth from slipping and causing the teeth to fall off the bite block body.

[0011] Preferably, in order to facilitate the integrated processing of the protective pad and the dental pad body, the protective pad and the dental pad body are integrally formed.

[0012] Preferably, to prevent the tongue from being caught between the bite pad body and the teeth, a tongue-blocking baffle is provided at the inner end of the bite pad body and connected to the protective pad. The baffle is higher than both the bite pad body and the protective pad. During installation of the bite pad body, the baffle further blocks the tongue from the inner side of the bite pad body, preventing a gap between the teeth and the bite pad body from causing the edge of the tongue to be squeezed into the gap and causing the tongue to be bitten. Furthermore, by designing the baffle higher than the bite pad body, when a gap is formed between the teeth and the bite pad body, the baffle provides protection, preventing the teeth from protruding into the gap.

[0013] The present application has a compact structure and is easy to operate. During the use of the cannula, the two protective pads clamped on the outside of the cannula can prevent the cannula from being bitten or broken, thereby ensuring the safety of the cannula during use. During the process of the upper and lower teeth biting the protective pads, the tongue can be blocked on the inside of the upper and lower teeth by the tooth pad body, thereby preventing the tongue from being located between the upper and lower teeth and being bitten.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] This embodiment provides a mouth guard for intubation protection, such as Figure 1-3 As shown, the dental pad includes a protective pad 1 relatively arranged between the upper and lower jaws for protecting the cannula, and an arc-shaped groove 11 opened between the two protective pads 1 for the cannula to pass through; during the use of the cannula, the two protective pads 1 clamped on the outside of the cannula can prevent the cannula from being bitten or broken, thereby ensuring the safety of the cannula during use.

[0021] To prevent the tongue from being bitten by the teeth due to muscle contraction, a bite block body 2 is fixedly connected to the two opposing ends of the two protective pads 1 for the upper and lower jaws to bite together. When the upper and lower teeth bite the protective pads 1, the bite block body 2 can block the tongue inside the upper and lower teeth, preventing the tongue from being caught between the upper and lower teeth and being bitten.

[0022] When in use, first bite the protective pad 1 and the dental pad body 2 between the patient's upper and lower teeth, and then pass the cannula through the inside of the two arc-shaped grooves 11, thereby preventing the cannula from being bitten or broken and preventing the tongue from being bitten, thereby improving the practicality of the dental pad.

[0023] Specifically, to improve the applicability of the protective pads 1, an installation gap 12 communicating with the arcuate groove 11 is provided between the two protective pads 1. During use, the two protective pads 1 can first be snapped onto the exterior of the cannula, and then the cannula and the protective pads 1 can be placed in the patient's mouth, with the patient's upper and lower teeth pre-engaged with the upper and lower end surfaces of the protective pads 1. When used on different patients, the installation gap 12 between the two protective pads 1 allows for a certain degree of misalignment without affecting cannula installation, allowing the dental pad to be adapted for different patients and improving its applicability.

[0024] Specifically, to facilitate installation of the bite block body 2, tooth grooves 21 corresponding to the teeth are formed at both the top and bottom ends of the bite block body 2. During installation, the tooth grooves 21 can be used to position the bite block body 2, preventing the teeth from slipping and causing the teeth to fall off the bite block body 2.

[0025] Specifically, in order to facilitate the integrated processing of the protective pad 1 and the dental pad body 2, the protective pad 1 and the dental pad body 2 are integrally formed.

[0026] Furthermore, to prevent the tongue from being caught between the bite pad body 2 and the teeth, a baffle 3 is connected to the inner end of the bite pad body 2 and the protective pad 1 to block the tongue. The baffle 3 is higher than the bite pad body 2 and the protective pad 1. During the installation of the bite pad body 2, the baffle 3 can further block the tongue inside the bite pad body 2, preventing the edge of the tongue from being squeezed into the gap between the teeth and the bite pad body 2 and causing tongue bite injuries. By designing the baffle 3 higher than the bite pad body 2, when a gap appears between the teeth and the bite pad body 2, the baffle 3 can provide protection and prevent the teeth from protruding into the gap.

[0027] It should be noted that the protective pad 1, the tooth pad body 2 and the baffle 3 are all made of methacrylic resin material. Methacrylic resin is one of the commonly used materials for making bite pads. It has high hardness and durability, can increase the hardness required for tooth occlusion, can effectively isolate the contact between the upper and lower teeth, protect the teeth and enamel, and reduce the tension and myoelectric activity of the jaw.

[0028] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
