Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical assistive devices, specifically to an oral and facial support device. Background Technology
[0002] In anesthesia and surgery, mask ventilation is a commonly used ventilation method, serving as the channel for gas exchange in anesthetized patients. During ventilation, ventilation difficulties often arise, causing significant challenges for anesthesiologists. Tooth loss is a common physiological phenomenon in the elderly, accounting for 25%-30.6% of all mask ventilation difficulties. With the advent of an aging society, more and more elderly patients, especially those without teeth, will undergo surgical treatment, leading to frequent air leakage problems during mask ventilation for general anesthesia in elderly patients with no teeth.
[0003] In current technologies, to address the issue of ventilation leakage in general anesthesia masks for elderly patients with missing teeth, operators often need to forcefully press down on the mask with both hands and support the chin to ensure a tight seal between the face and the mask, thus reducing leakage. Simultaneously, another assistant quickly inflates the mask and squeezes the bag to deliver oxygen. Some also use two rolled-up gauze pads placed between the sunken cheek and the mask to increase the fit and reduce leakage. Currently, most methods rely on the doctor's on-the-spot reaction, and no mask can completely solve these problems. None can guarantee smooth ventilation, often leading to critical situations such as the inability to ventilate through the mask. Utility Model Content

[0042] To make the objectives, technical solutions, and advantages of this utility model more apparent, exemplary embodiments according to this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, and not all embodiments of this utility model. It should be understood that this utility model is not limited to the exemplary embodiments described herein. Based on the embodiments of this utility model described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this utility model.
[0043] Therefore, in view of the aforementioned technical problems, this utility model proposes an oral and facial support device, such as... Figure 1-4 As shown. The oral and facial support includes an external component 1, a limiting rolled edge 2, a support member 3, a fixing block 4, and a pull block 5, as shown. Figure 1 As shown.
[0044] External component 1 is used to cover the gum surface and support the face. External component 1 is installed between the lips and gums to support the face of a patient with missing teeth. This prevents leakage of anesthetic gas due to gaps between the face and the anesthesia mask caused by facial collapse during anesthesia.
[0045] The external component 1 is provided with a limiting flange 2 for limiting its position. The limiting flange 2 and the external component 1 form a groove 7, which holds the patient's gums in place, limiting the external component 1 and further limiting the orofacial support. This prevents the orofacial support from falling off or shifting. If the external component 1 is not limited, the orofacial support may be installed to the right or left, causing the other side of the face to still collapse, thus rendering the orofacial support ineffective. The external component 1 and the limiting flange 2 can be a single unit or detachable.
[0046] A support member 3 is provided on the limiting rolled edge 2 to support the opening. For example... Figure 4 As shown, the support member 3 is provided with a channel 6, which passes through the outer component 1, the limiting rolled edge 2, and the support member 3. The support member 3 is used to support the size of the mouth opening and prevent the patient from squeezing the channel 6 between the outer component 1 and the limiting rolled edge 2, thus reducing its size.
[0047] The support member 3 is equipped with more than one fixing block 4 for securing it. The fixing block 4 is a protruding block located at the end of the support member 3 that inserts into the oral cavity, and can be made of polycarbonate. When the fixing block 4 enters the oral cavity, the support member 3 engages with the external component 1 and the limiting flange 2, preventing the support member 3 from moving or falling out. Without the fixing block 4, the support member 3 and the oral support can be inserted into the oral cavity very smoothly, but the support member 3 may be pulled out. With the fixing block 4, the fixing block 4 at the end of the support member 3 that inserts into the oral cavity protrudes, so the oral support needs to be squeezed to insert it. At this time, a clamping force is formed between the fixing block 4 and the support member 3, holding the oral support in the middle and preventing the support member 3 from falling out. The fixing block 4 and the support member 3 can be a single unit or detachable. Figure 4 As shown, in one embodiment, the number of fixed blocks 4 is 4.
[0048] A pull block 5 is provided on the side of the support member 3 away from the fixing block 4 for removing the oral facial support. Since the size of the outer component 1 does not completely cover the area between the lips and gums, by rotating the pull block 5 to the left or right at a certain angle, the outer component 1 in the other direction can be tilted outwards from the lips and removed, thus allowing the oral facial support to be removed. For example, rotating it to the left at a certain angle will create a gap between the right side of the oral facial support and the lips and gums, allowing it to be pulled out at an angle to the right. Similarly, rotating it to the right at a certain angle will create a gap between the left side of the oral facial support and the lips and gums, allowing it to be pulled out at an angle to the left. The number of pull blocks 5 can be greater than one. Figure 3 As shown, in one embodiment, the number of pull blocks 5 is 2.
[0049] According to the present invention, the oral and facial support device supports the concave oral and facial area of a patient with missing teeth through an external component 1 and supports the mouth opening through a support member 3, thereby increasing the fit between the oral and facial area and the anesthesia mask and solving the problem of air leakage during the ventilation of the anesthesia mask for patients with missing teeth.
[0050] In one embodiment, the length of the outer component 1 along the first direction is greater than the length of the outer component 1 along the second direction; the length of the limiting rolled edge 2 along the first direction is greater than the length of the limiting rolled edge 2 along the second direction; the length of the support member 3 along the first direction is greater than the length of the support member 3 along the second direction; the first direction is perpendicular to the second direction. Since the length of the lip is greater than its width, this design allows the outer component 1, the limiting rolled edge 2, and the support member 3 to conform to the shape of the lip.
[0051] In one embodiment, the length of the outer component 1 along the first direction is greater than the length of the limiting curl 2 along the first direction; the length of the outer component 1 along the second direction is greater than the length of the limiting curl 2 along the second direction; a groove 7 is formed between the outer component 1 and the limiting curl 2, and the groove 7 is used to accommodate the gum.
[0052] External component 1 is positioned on the side of the gum near the lips, and limiting curled edge 2 is positioned on the side of the gum near the oral cavity. The area of external component 1 is larger than the area of limiting curled edge 2. Figure 2 As shown in the cross-sectional view, the edge of the external component 1 and the edge of the limiting rolled edge 2 form a groove 7, which holds the patient's gums in the groove 7 and limits the external component 1. This further limits the orofacial support, preventing the orofacial support from falling off or shifting. When the external component 1 is not limited, the installation position of the orofacial support may be biased to the right or left, causing the other side of the face to still collapse, thus resulting in the orofacial support failing to provide support.
[0053] In one embodiment, the pull block 5 protrudes along the side of the support 3 away from the fixing block 4; the surface of the pull block 5 is provided with a tension groove 51; the tension groove 51 is recessed into the pull block 5. The number of tension grooves 51 can be greater than one. The tension groove 51 is recessed into the pull block 5, forming a gripper-like shape, making it easy for medical personnel to grasp the pull block 5. Medical personnel can rotate the pull block 5 to the left or right using the tension groove 51 to remove the oral and facial support. The size of the external component 1 does not completely cover the area between the lips and gums. After rotating the pull block 5 to the left or right at a certain angle, the external component 1 in the other direction can be tilted outwards towards the lips and removed, thus removing the oral and facial support. If rotated to the left at a certain angle, a certain gap will form between the right side of the oral and facial support and the lips and gums, allowing it to be pulled out at an angle to the right. If rotated to the right at a certain angle, a certain gap will form between the left side of the oral and facial support and the lips and gums, allowing it to be pulled out at an angle to the left. Figure 3 As shown, in one embodiment, the number of tension grooves 51 in each pull block 5 is 2.
[0054] In one embodiment, a strip block 52 is provided within the tension groove 51; the strip block 52 is used to increase the friction between the hand and the pull block 5. Figure 3 As shown, each tension groove 51 contains a strip block 52. When the tension groove 51 is not equipped with a strip block 52, the surface of the tension groove 51 is smooth, and the friction between the medical staff's hand and the pull block 5 is small, which may cause the hand to slip and make it difficult to remove the mouth and face support. The strip block 52 increases the friction between the hand and the pull block 5, making it easier to remove the mouth and face support.
[0055] In one embodiment, the outer component 1 and the limiting rolled edge 2 are made of silicone material. The outer component 1 and the limiting rolled edge 2 have high rigidity, which facilitates their supporting function.
[0056] In one embodiment, a first buffer pad 8 is provided on the side of the outer component 1 near the limiting rolled edge 2 to reduce the pressure of the outer component 1 on the gums. The shape of the first buffer pad 8 conforms to the shape of the outer component 1, which facilitates reducing the pressure of the outer component 1 on the gums.
[0057] In one embodiment, a second buffer pad 9 is provided on the side of the limiting rolled edge 2 near the outer component 1 to reduce the pressure of the limiting rolled edge 2 on the gums. The shape of the second buffer pad 9 conforms to the shape of the limiting rolled edge 2, which facilitates reducing the pressure of the limiting rolled edge 2 on the gums.
[0058] In one embodiment, the first buffer pad 8 and the second buffer pad 9 are made of silicone. The first buffer pad 8 and the second buffer pad 9 have low hardness, which helps protect the patient's gums. The first buffer pad 8 is disposed between the external component 1 and the second buffer pad 9, and the second buffer pad 9 is disposed between the limiting rolled edge 2 and the first buffer pad 8.
[0059] In one embodiment, the outer component 1, the limiting rolled edge 2, and the support member 3 have the same axis. The outer component 1, the limiting rolled edge 2, and the support member 3 can be elliptical in shape, and their centers are the same.
[0060] This concludes the introduction to the structure of the oral and facial support of this utility model. A complete oral and facial support may also include other components, which will not be described in detail here.
[0061] According to the present invention, the oral and facial support device supports the concave oral and facial area of a patient with missing teeth through an external component, the limiting rolled edge fixes the external component, and the support member supports the mouth opening, increasing the fit between the oral and facial area and the anesthesia mask, so as to solve the problem of air leakage during the ventilation of the anesthesia mask for patients with missing teeth. A pull block is provided on the support member to facilitate the removal and placement of the oral and facial support device.
