DETAILED DESCRIPTION OF THE INVENTION

[0029] The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be utilized or constructed. The description sets forth the functions of the example and the sequence of steps for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples.

[0030] Although the terms first, second, third, etc. may be used herein to describe various distance, longitudinal surface, and/or malposition, these distance, longitudinal surface, and/or malposition should not be limited by these terms. These terms may be only used to distinguish one distance, longitudinal surface or malposition from another distance, longitudinal surface or malposition. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first distance, longitudinal surface or malposition discussed below could be termed a second distance, longitudinal surface or malposition without departing from the teachings of the example embodiments.

[0031] With reference now to the figures, and in particular, with reference to FIG. 1, a diagram of a medical bite block is depicted in which an advantageous embodiment the present invention may be implemented. Additionally, FIG. 2 is a sectional view of a user's upper teeth and lower teeth being bitten in accordance with one embodiment of the present invention. The medical bite block 100 integrated as one-piece that is provided for a user to bite is inserted into and installed into the user's oral cavity O. The medical bite block 100 includes a through passageway 1, an upper biting grove 2, and a lower biting grove 3 at least. The through passageway 1 is penetrating through the medical bite block 100. One end of the through passageway 1 comprises an inlet opening 11, the other end comprises an oral opening 12. In addition, the oral opening 12 is used to connected with an oral cavity O of the user, and the inlet opening 11 is used to penetrate the endoscope device (figure is not shown). An upper surface of the medical bite block 100 provides the upper biting grove 2, and the upper biting grove 2 is provided for the upper teeth (maxillary teeth) T1, especially upper front teeth, to bite, engage and lock correspondingly. On the other hand, a lower surface of the medical bite block 100 provides a lower biting grove 3, and the lower biting grove 3 is provided for the lower teeth (mandibular teeth) T2, especially lower front teeth, to bite, engage and lock correspondingly. Additionally, the medical bite block would define a first distance from the upper biting grove 2 to the oral opening 12 along with the axis 13 and would define a second distance from the lower biting grove 3 to the oral opening 12 along with the axis 13. Thus, the second distance between the lower biting grove 3 and the oral opening 12 is greater than the first distance between the upper biting grove 2 and the oral opening 12, thereby the lower biting grove 3 is away from the oral cavity O of the user relative to the upper biting grove 2. Furthermore, the lower biting grove 3 and the upper biting grove 2 form a first malposition with each other corresponding to lower teeth T2 and upper teeth T1 respectively.

[0032] Moreover, please refer FIG. 2, FIG. 3 and FIG. 4, the upper biting grove 2 is perpendicular to an axis 13 of the through passageway 1, which further comprises a first longitudinal surface P1. Also, the lower biting grove 3 is perpendicular to an axis 13 of the through passageway 1, which further comprises a second longitudinal surface P2. Additionally, the first longitudinal surface P1 and the second longitudinal surface P2 is not overlapped but is corresponded, and the second distance between the second longitudinal surface P2 and the oral opening 12 is greater than the first distance between the first longitudinal surface P1 and the oral opening 12. A third distance between the first longitudinal surface P1 and the second longitudinal surface P2 is, for example but not limited to, 1 to 12 mm. That is to say, the third distance along with the axis 13 of the through passageway 1 between the upper biting grove 2 and the lower biting grove 3 is about 1 to 12 mm, but is not limited thereto.

[0033] As depicted therein, while the medical bite block 100 was installed into the mouth of the user, the upper biting grove 2 of the medical bite block 100 could be provided for receiving the user's upper teeth T1 bitten, engaged and locked. The lower biting grove 3 of the medical bite block 100 could be provided for the user's lower teeth T2 to bite, engage and lock. So that the user's upper teeth T1 and lower teeth T2 could bite, engage and lock the medical bite block 100 without requiring strenuous effort to extend forward the user's lower jaw beyond his upper jaw and his upper teeth. Furthermore, the user could use the medical bite block 100 to extend forward his lower jaw beyond his upper jaw and his upper teeth even in a lying down position (supine position) after anesthesia, especially after deep anesthesia, to avoid the tongue fall down caused upper airway obstruction. Therefore, the medical bite block of the present invention can decrease the risk of hypoxia during endoscopic inspection.

[0034] In addition, with reference now to FIG. 3, FIG. 4, FIG. 5 and FIG. 6, the present invention also comprises an inspiration tube 6 and an expiration tube 7 which are situated in the outer surface of the vertical direction of the inlet opening 11 and oral, opening 12 respectively. Consequently, the user could have steady oxygen resource through inspiration tube 6 by oxygen providing system such as an oxygen cylinder or a liquid oxygen reservoir, and exhale the carbon dioxide from the nasal cavity and oral cavity through expiration tube 7 by the medical bite block 100 of the present invention. However, the present disclosure may not be limited thereto.

[0035] In other embodiment, for example those shown in FIG. 4, FIG. 5 and FIG. 6, an oral inspiration and expiration part 4 is situated inside the inner wall of the through passageway 1 as a ring shape. The oral inspiration and expiration part 4 further comprises a proximal inspiration channel 41 and a distal expiration channel 42. In addition, the proximal inspiration channel 41 and the distal expiration channel 42, which form as the ring shape situated at the oral inspiration and expiration part 4 and are located adjacent to each other, further form a second malposition with one another. Next, the medical bite block would define a fourth distance from proximal inspiration channel 41 to the oral opening 12 along with the axis 13 and would define a fifth distance from the distal expiration channel 42 to the oral opening 12 along with the axis 13. Moreover, the fourth distance between proximal inspiration channel 41 and the oral opening 12 is shorter than the fifth distance between the distal expiration channel 42 and the oral opening 12, thus the distal expiration channel 42 is away from the oral cavity of the user relative to the proximal inspiration channel 41. Consequently, the proximal inspiration channel 41 and the distal expiration channel 42 form the second malposition with each other. In other instances, the proximal inspiration channel 41 and the distal expiration channel 42 further comprise a central partition member 43. The central partition member 43 is used to separate the proximal inspiration channel 41 from the distal expiration channel 42.

[0036] In another word, oxygen could be facilitated to be transported from inspiration tube 6 across the proximal inspiration channel 41 passing over oral cavity O to the upper respiratory tract of the user with a shorter distance than existed technique and product. So much so that the user could easily receive oxygen by the medical bite block of the present invention during anesthesia. Besides, the oxygen distributed in the proximal inspiration channel 41 and the carbon dioxide dispersed in the distal expiration channel 42 wouldn't mixed together due to the central partition member 43, so that the oxygen and the carbon dioxide could easily be inhaled and exhaled respectively by the proximal inspiration channel 41 and the distal expiration channel 42 while the user used the medical bite block 100 during endoscopic inspection after anesthesia.

[0037] In other hand, the present invention further comprises a nasal inspiration and expiration part 5 as shown in FIG. 4. The nasal inspiration and expiration part 5 is wing-shaped and is corresponded with the upper lip, that is the nasal inspiration and expiration part 5 is configured to establish a correspondence from the external nares to the upper lip vermillion. Furthermore, as seen in to FIG. 5 and FIG. 6, the nasal inspiration and expiration part 5 further comprises an inspiration and expiration duct 51. As a result, the user could inhale oxygen and exhale carbon dioxide more effectively by nasal inspiration and expiration part 5 of the present invention.

[0038] Certainly, the central partition member 43 is, but not limited to, extended from the oral inspiration and expiration part 4 to the nasal inspiration and expiration part 5. Hence, inspiration tube 6 is connected with the proximal inspiration channel 41 and nasal inspiration and expiration part 5. More accurately, the inspiration tube 6, the proximal inspiration channel 41, and the inspiration and expiration duct 51 are all specifically connected one another. As a consequence, the present invention could provide oxygen for user with shorter distance by proximal inspiration channel 41 and nasal inspiration and expiration part 5. On the other hand, the expiration tube 7 is connected with the distal expiration channel 42 and the nasal inspiration and expiration part 5. Namely, the expiration tube 7, the inspiration and expiration duct 51, and the distal expiration channel 42 are all specifically connected one another. To sum up, the present invention could provide oxygen to the oral cavity and nasal cavity of the user with shorter distance by proximal inspiration channel 41 and nasal inspiration and expiration part 5. Thus, the central partition member 43 is provided between the oral inspiration and expiration part 4 and the nasal inspiration and expiration part 5. In conclusion, the oxygen from the inspiration tube 6 could directly pass through proximal inspiration channel 41 and nasal inspiration and expiration part 5 in order to be supplied the user inhaling. On the contrary, the carbon dioxide would be removed from distal expiration channel 42 and nasal inspiration and expiration part 5 through expiration tube 7 to be expelled from the medical bite block 100.

[0039] As set out above, the user could use his upper teeth T1 and lower teeth T2, especially his upper front teeth and lower front teeth, to bite, engage and lock the upper biting grove 2 and the lower biting grove 3 respectively. In another word, it is characterized by the user's lower jaw extending out, causing his lower front teeth to sit in front of his upper front teeth, while the user could use the medical bite block 100 of the above-mentioned present invention even in a lying down position (supine position) after anesthesia, especially after deep anesthesia, to avoid the tongue fall down caused upper airway obstruction and further can reduce the chances of hypoxia. Besides, the inspiration tube 6, the proximal inspiration channel 41 and the nasal inspiration and expiration part 5 are all specifically connected one another, so that the present invention could more effectively provide oxygen for user with a shorter distance in particular.
