In this regard, the middle section 70 is an intermediate between the first leg 7A and the second leg 7B. The first end 5A is opposite the end of the first leg 7A that is joined to the middle section 70. Similarly, second end 5B is opposite the end of the second leg 7B that is joined to the middle section 70. In one embodiment the middle section 70 and first leg 7A and second leg 7B are composed as a single piece. In an alternative embodiment the middle section 70 and first leg 7A and second leg 7B can be more than one piece that are connected.

[0026] The top surface 10 of the bite block 1 may be smooth. In other embodiments the top surface 10 may be rough to prevent the bite block 1 from slipping while in the mouth of the patient. The top surface 10 may also have a trough to accommodate the teeth or gums of a patient. In a further embodiment, the top surface may be configured to receive a material to help in holding the user's teeth in place. The material can be a reusable sticky or tacky material or any similar material that is pliable and allows for forming around and in communication with the teeth of a patient. The material will still allow the bite block to be removed but can engage the teeth of the patient. In a further embodiment the top surface may have indicia or raised members 15 to create surface area that communicates with a user's teeth. Similarly, the bottom surface 20 of the bite block 1 may be smooth. In another embodiment, the top surface 10 and the bottom surface 20 can include any means known in the industry to create traction between the bite block and a user's teeth such as may have ridges to prevent the bite block 1 from slipping while in a patient's mouth. In other embodiments the bottom surface 20 may be rough to prevent the bite block 1 from slipping while in the mouth of the patient. The bottom surface 20 may also have a trough or indentions to accommodate the teeth or gums of a patient. In an additional embodiment the top surface 10 and the bottom surface 20 may be formed from a soft material which allows the bite block 1 to accommodate a patient's teeth. In this regard, the top surface 10 and the bottom surface 20 may be softer than the other parts of the bite block 1. The top surface 10 and the bottom surface 20 may have indicia or raised members 15 for assisting in placement of the bite block 1. The indicia may also provide friction or roughness for preventing the bite block 1 from slipping out of a patient's mouth and can be composed of material that is softer or tacky or sticky to create the connection with the patient's teeth.

[0027] The bite block 1 may have a wedge like shape where the section of the bite block 1 nearest the first end 5A and second end 5B is thinner than the middle section 70. In this regard, the bite block 70 may have dimensions that allow the bite block 1 to fit in the mouth of a patient. One of skill in the art will appreciate that the middle section 70 of the bite block 1 may have the same thickness or be thinner than the first or second ends 5A and 5B. In an alternative embodiment the bite block 1 may have varying widths to allow for the placement in the mouth of a patient.

[0028] As shown in FIGS. 1-7, the middle section 70 of the bite block 1 may have a center cutout 50. The middle cutout 50 may be used to accept an endotracheal tube or other instruments and/or items that will be used during a patient's medical procedure. As shown in FIG. 1, the center cutout 50 may have a U shape. While the center cutout 50 is preferably U shaped, the center cutout 50 may have any shape suitable for accepting tubes, including a square, triangle, pentagon, hexagon, septagon, octagon, or any other suitable shape known in the art. One of skill in the art will appreciate that the center cutout 50 may be dimensioned to accept any size of endotracheal tube known in the art. The center cutout 50 allows the user to place a tube such as an endotracheal tube in a patient's mouth without pushing the tube through a hole therefore increasing the ease of use. In this regard, the bite block 1 may be used with tubes that have a balloon or cuff because the balloon or cuff portion of the tube does not have to be pushed through an aperture. Instead, the U-shaped center cutout 50 allows a user to place or rest a tube in the center cutout 50.

[0029] The middle section 70 of the bite block 1 may also have a first side aperture 60A and a second side aperture 60B that open relative to the bottom surface 20 to create an opening slot. The first and second side apertures may be on each side of the middle cutout 50. As shown in FIGS. 1-7, the first and second aperture 60A and 60B may allow tube placement by allowing the tube to rest in the first or second aperture 60A, and 60B. In an additional embodiment, the bite block can be configured with the first and second apertures 60A and 60B open to the top surface 10. The configuration of the number of apertures on the top or bottom surface may be dependent on the tubes or instruments to be used during a procedure. The configuration of these apertures 60A and 60B are designed to be useful for placing and holding one or more tubes in the bite block 1 while a procedure is performed. Side apertures 60A and 60B may be configured to accept a gastric tube or any other tube and/or instrument or item used for intubation or the patient's procedure. One of skill in the art will appreciate there may be more than two side apertures in the bite block 1. The shape and size of the first and second side apertures can vary dependent on the user and the procedure to be performed. As shown the first and second side apertures 60A and 60B may have a square shape. The first and second side apertures 60A and 60B may have a circle shape or any shape to allow for use during a procedure. One of skill in the art will appreciate that the first and second side apertures 60A and 60B may be configured and dimensioned to accept any size of surgical tube instrument, or surgical item known in the art. The first and second side apertures allow the user to place a tube such as a gastric tube in a patient's mouth without pushing the tube through a hole. Instead, the U-shaped center cutout 50 allows a user to place or rest a tube in the center cutout 50. These configurations allow for each placement by a medical personal as well as provide comfort for a user during a procedure.

[0030] In an additional embodiment each side aperture 60A and 60B may have a separable popout section disposed within the side aperture. The center cutout 50 may also have a separable popout section disposed within the center cutout 50. The separable popouts provide the user the ability to determine the number or size of apertures needed for a procedure. A user may remove the popout sections according to the desired aperture configuration. In this regard, the bite block 1 can have various numbers of popouts for a desired configuration and is therefore customizable by the medical personal for use with the desired procedure.

[0031] The bite block 1 can also include a configuration that allows for the acceptance of a strap or other holding mechanism. This holding mechanism, such as a strap is designed help hold the bite block in place while the procedure is being perform. Alternatively, the strap can be used to also help hold tubes or instruments being used in place to minimize harm to a patient or disruption to the procedure.

[0032] The bite block 1 may be formed from a resilient material that has strength to withstand an evoked biting response. The material should also be soft enough to prevent damage to the gums, lips, teeth, if a biting response is evoked. The bite block 1 material has enough strength to withstand and resist biting force, preventing a patient from biting down on a tube placed through a side aperture 60A or 60B or center cutout 50 in the bite block 1. The bite block 1 may be formed from a pliable material such as rubber, polyvinylidene fluoride or polyvinylidene difluoride (PVDF), or other polymers known in the art. In further embodiments the bite block may be formed from more than one type of material to allow for a more pliable outer surface with a more ridged inner configuration to withstand a biting response. The more pliable outer surface can be configured to allow for a user's teeth be held securely and communicate with the bite block. In some embodiments the bite block 1 may be placed in patients that are imaged using MRI. Bite blocks used during MRI may be formed from a non-ferrous material. The bite block 1 may be translucent, allowing a user to see through the bite block 1. The bite block 1 may also be formed from a radiolucent material to allow for imaging. In one embodiment, the bite block 1 is single use. Embodiments of the bite block 1 may be compostable. In compostable embodiments, the bite block 1 may be formed from a compostable material known in the art. In an additional embodiment the bite block 1 may be reusable.
