[0030] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.
[0031] Referring to Figures 1 - 5 As shown in the figure, an embodiment of the present utility model provides a mouth pad for a gastroscope, which includes a mouth pad body 1, a tongue depressor 2 and a fixing band 3. The inside of the mouth pad body 1 has a gastroscope channel 11; the tongue depressor 2 includes a first tongue-depressing part 21 and a second tongue-depressing part 22 which are connected to each other. The first tongue-depressing part 21 extends along the axial direction parallel to the mouth pad body 1 and is connected to the mouth pad body 1. The second tongue-depressing part 22 is connected to one end of the first tongue-depressing part 21 away from the mouth pad body 1. The second tongue-depressing part 22 is arc-shaped and bends towards the direction away from the central axis of the mouth pad body 1; the fixing band 3 has two ends respectively connected to both sides of the mouth pad body 1 to form a restraint opening.
[0032] The restraint opening formed by the fixing band 3 can be used to wear the mouth pad for a gastroscope on the head of the user, forming a restraint on the position of the mouth pad, so that the mouth pad is fixed in the mouth of the user, preventing the user from spitting out the mouth pad, and thus making the mouth pad more stable in the user's mouth; the mouth pad for a gastroscope is inserted into the user's mouth, and the gastroscope channel 11 for the gastroscope body to pass through is provided by the mouth pad body 1, preventing the gastroscope body from being damaged due to the user's mouth biting. The tongue is pressed by the tongue depressor 2 to prevent problems such as hypoxia caused by the posterior sagging of the tongue leading to airway obstruction. Moreover, since the tongue depressor 2 includes the first tongue-depressing part 21 and the second tongue-depressing part 22, and the second tongue-depressing part 22 is arc-shaped and bent, the whole tongue depressor 2 has a certain bending angle, which better conforms to the shape of the user's tongue body, improves the pressing effect on the tongue and reduces the discomfort of the user.
[0033] It should be noted that the arc center of the second tongue-depressing part 22 is located outside the mouth pad body 1. The central axis of the arc of the second tongue-depressing part 22 is coplanar with the end face of the first tongue-depressing part 21 close to the second tongue-depressing part 22, and this plane is parallel to the cross-section in the radial direction of the mouth pad body 1. When the second tongue-depressing part 22 presses on the user's tongue, the second tongue-depressing part 22 can provide a top thrust towards the outside of the oral cavity to the user's tongue root, improving the effect of preventing the tongue from posterior sagging.
[0034] Referring to Figures 1 - 5As shown, in some embodiments, the cross-section of the mouthpiece body 1 parallel to the radial direction is elliptical, and the first tongue-depressing part 21 is connected to one of the vertices of the minor axis of the mouthpiece body 1. Both the first tongue-depressing part 21 and the second tongue-depressing part 22 are plate-shaped, which increases the contact area between the tongue-depressing plate 2 and the tongue, and the tongue-depressing plate 2 is in surface contact with the tongue, avoiding pressing damage to the tongue and preventing the two sides of the tongue from warping up, which may affect the insertion of the gastroscope body. The first tongue-depressing part 21 is connected to the vertex of the minor axis of the mouthpiece body 1. When the tongue-depressing plate 2 presses on the tongue, the minor axis direction of the mouthpiece body 1 is the opening and closing direction of the mouth, which is the width direction of the mouthpiece body 1, avoiding excessive opening and closing of the user's mouth. The size of the butt joint surface between the second tongue-depressing part 22 and the first tongue-depressing part 21 is equal, which is convenient for the manufacturing and forming of the first tongue-depressing part 21 and the second tongue-depressing part 22, especially for the bending and forming of the second tongue-depressing part 22. In some embodiments, the first tongue-depressing part 21 is straight plate-shaped, and the second tongue-depressing part 22 is arc plate-shaped. The cross-sectional contour shapes of both the first tongue-depressing part 21 and the second tongue-depressing part 22 parallel to the radial direction of the mouthpiece body 1 are rectangular. Further, in order to avoid the outer contours of the first tongue-depressing part 21 and the second tongue-depressing part 22 being too sharp and causing abrasions to the oral cavity, the sides in the length direction of the first tongue-depressing part 21 and the second tongue-depressing part 22 are all transitioned with rounded corners.
[0035] In some embodiments, the included angle between the line connecting the two ends of the second tongue-depressing part 22 and the central axis of the mouthpiece body 1 is 30°.
[0036] Refer to Figures 1 - 5 As shown, in some embodiments, the cross-sectional contour shape of the gastroscope channel 11 parallel to the radial direction of the mouthpiece body 1 is elliptical. The axial length of the mouthpiece body 1 is 2.5 cm, the major axis length of the cross-section of the gastroscope channel 11 is 3 cm, and the minor axis length is 2 cm, which is convenient for the gastroscope examination mirror to enter the patient's oropharynx.
[0037] Refer to Figures 1 - 5 As shown, in some embodiments, a first wing plate 4 is provided at one end of the mouthpiece body 1 away from the tongue-depressing plate 2. The first wing plate 4 is fixed on the outer peripheral side of the mouthpiece body 1 and is coaxially arranged with the mouthpiece body 1. When the mouthpiece body 1 is inserted into the oral cavity, the first wing plate 4 is kept outside the oral cavity, and the first wing plate 4 plays a role in limiting the position of the mouthpiece body 1 inserted into the oral cavity. It should be noted that the first wing plate 4 has a through hole communicating with the gastroscope channel 11. The fixing strap 3 can be fixed on the first wing plate 4, so that the fixing strap 3 does not need to enter the oral cavity. In some embodiments, the outer contour shape of the cross-section of the first wing plate 4 parallel to the radial direction of the mouthpiece body 1 is elliptical. The minor axis length of the first wing plate 4 is 3.5 cm.
[0038] Refer to Figure 6As shown, in some embodiments, a fixing plate 6 is provided on each of the upper and lower sides of the first wing plate 4. The fixing plate 6 can be used to bond the tape, which is convenient for using the tape to fix the first wing plate 4 on the outer periphery of the oral cavity, thereby facilitating the fixation of the overall oral pad. When in use, the tape can be first pasted on the fixing plate 6 to preliminarily fix the first wing plate 4, and then the fixing band 3 is sleeved on the user's head to perform double fixation on the oral pad, ensuring the stability of the oral pad fixed in the oral cavity.
[0039] Referring to Figures 1 - 5 As shown, in some embodiments, a second wing plate 5 is provided at one end of the oral pad body 1 close to the tongue depressor 2. The second wing plate 5 is fixed on the outer peripheral side of the oral pad body 1 and is coaxially arranged with the oral pad body 1. The tongue depressor 2 is fixed on the side of the second wing plate 5 away from the oral pad body 1.
[0040] In some embodiments, in the axial direction of the oral pad body 1, the sum of the lengths of the oral pad body 1 and the tongue depressor 2 is 6 cm or 7 cm. It should be noted that when the oral pad body 1 is provided with the first wing plate 4 and the second wing plate 5, the sum of the lengths of the oral pad body 1 and the tongue depressor 2 includes the lengths of the first wing plate 4 and the second wing plate 5.
[0041] In some embodiments, the first tongue-depressing part 21 and the second tongue-depressing part 22 are integrally formed, which is convenient for manufacturing and forming, and avoids local injury to the user's tongue caused by a protruding node at the connection between the first tongue-depressing part 21 and the second tongue-depressing part 22. The second wing plate 5, the first tongue-depressing part 21 and the second tongue-depressing part 22 can be integrally formed. For example, the tongue depressor 2 formed by the first tongue-depressing part 21 and the second tongue-depressing part 22 can be arc-shaped and is integrally connected with the elliptical arc of the second wing plate 5 in a matching manner. The oral pad body 1, the first tongue-depressing part 21 and the second tongue-depressing part 22 are all made of hard materials. The oral pad body 1 includes an inner layer and an outer layer. The outer layer is provided on the outer peripheral side of the inner layer. The outer layer and the inner layer can be adhesively fixed or integrally formed. The gastroscope channel 11 is formed in the inner layer. Both the outer layer and the inner layer are hard PVC plate members. Both the outer layer and the inner layer are made of PVC material, specifically hard PVC material. By using a double-layer hard PVC plate member to form the oral pad body 1, the strength of the oral pad body 1 can be improved, and damage to the oral pad body 1 caused by tooth biting can be avoided.
[0042] Both ends of the fixing strap 3 are fixedly connected to the mouth pad body 1, and the end of the fixing strap 3 can be fixed to the outer edge of the first wing plate 4. When the outer contour shape of the cross-section of the first wing plate 4 parallel to the radial direction is an ellipse, the two ends of the fixing strap 3 are respectively fixed at the two end points of the minor axis of the ellipse, which is convenient for winding the fixing strap 3 around the restraint mouth formed by the mouth pad body 1 and putting it on the user's head, and applying a binding force towards the user's oral cavity to the mouth pad body 1. In some embodiments, the fixing strap 3 is an elastic strap. The elastic strap has a certain elasticity, so that the fixing strap 3 can be suitable for users with different head circumferences and improve the comfort of the users.
[0043] In other embodiments, the fixing strap 3 may further include two separate restraint straps, namely a first restraint strap and a second restraint strap. One end of the first restraint strap and the second restraint strap are respectively fixedly connected to the mouth pad body 1, and the other end of the first restraint strap is detachably connected to the other end of the second restraint strap. For example, buckles are respectively provided on the first restraint strap and the second restraint strap, and the two are detachably connected through the cooperation of the buckles. Mother-of-pearl buttons or the like may also be respectively provided on the first restraint strap and the second restraint strap, and the two are detachably connected through the cooperation of the mother-of-pearl buttons; alternatively, the first restraint strap and the second restraint strap may also be connected by means of manual lacing, and the ends of the two restraint straps are directly tied together.
[0044] The working process of the utility model is as follows:
[0045] During use, the end of the mouth pad body 1 connected to the tongue depressor 2 is placed in the user's oral cavity, and the tongue is pressed by the tongue depressor 2 to prevent the tongue from falling backward. Moreover, when placing the mouth pad, the first wing plate 4 is located outside the user's oral cavity, the insertion position of the mouth pad is limited by the first wing plate 4, the fixing strap 3 is arranged around the user's head, and a binding force towards the oral cavity is applied to the mouth pad through the fixing strap 3 to prevent the user from spitting out the mouth pad. The gastroscope body enters the user's oral cavity through the gastroscope channel 11 of the mouth pad body 1 and enters the detection site along organs such as the oral cavity, root of the tongue, pharynx, and esophagus for examination.
[0046] In summary, the embodiment of the present utility model provides an oral pad for gastroscope. The restraint opening formed by the fixing band 3 can be used to wear the oral pad for gastroscope on the head of the user, so that the oral pad is fixed at the mouth of the user, preventing the user from spitting out the oral pad, thereby making the oral pad more stable at the mouth of the user. The oral pad for gastroscope is inserted into the user's mouth. The oral pad body 1 provides a gastroscope channel 11 for the gastroscope body to pass through, preventing damage to the gastroscope body caused by the user's biting of the mouth. The tongue is pressed by the tongue depressor 2 to prevent hypoxia problems such as airway obstruction caused by the posterior sagging of the tongue. Moreover, since the tongue depressor 2 includes a first tongue pressing portion 21 and a second tongue pressing portion 22, and the second tongue pressing portion 22 is arc-shaped and bent, the whole tongue depressor 2 has a certain bending angle, which is more conformable to the tongue shape of the user, improving the pressing effect on the tongue and reducing the discomfort of the user.
[0047] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
