[0005] , ,

[0001] The present invention relates to a method for manufacturing a cover and a cover product, and particularly to a method for manufacturing an oropharyngeal cover and an oropharyngeal cover.

Background Art

[0002] During oral treatment (or oral cleaning), if liquids such as saliva and water are accidentally inhaled, it is likely to cause choking discomfort. During actual operation, the liquid in the human oral cavity is sucked out by a saliva suction tube. However, people who habitually breathe through the mouth, people who have undergone oral tumor surgery, or dementia patients are still likely to accidentally inhale the liquid in the oral cavity, which makes them prone to choking, feel more uncomfortable, try to interrupt the treatment, and may even develop aspiration pneumonia.

[0003] Also, during oral treatment (such as tooth extraction), dental patients may accidentally swallow foreign objects such as extracted teeth and other dental instruments, which may also make them feel uncomfortable, try to interrupt the treatment, and even lead to an emergency situation, and ultimately the dental patients may be at risk.

[0004] In recent years, in order to avoid the above situations, dentists place a shielding object (i.e., an oropharyngeal cover) at the oropharyngeal area of the patient (i.e., the position of the oropharyngeal airway in the patient's oral cavity) to prevent the patient from accidentally inhaling liquids such as saliva and water or foreign objects such as extracted teeth and other dental instruments during oral treatment (or oral cleaning).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, conventional oropharyngeal cover designs primarily focus on protecting the oral cavity and pharynx, without considering the manufacturing efficiency of the oropharyngeal cover. Under these circumstances, oropharyngeal covers cannot be mass-produced quickly, resulting in high costs and limited applicability during oral treatment (or oral cleaning).

[0006] In light of this, resolving the aforementioned issues present in conventional oral and pharyngeal covers and effectively improving the manufacturing efficiency of oral and pharyngeal covers has become an urgent issue in this technological field that needs to be addressed as soon as possible. [Means for solving the problem]

[0007] To solve the above problems, one aspect of the present invention provides a method for manufacturing an oral pharyngeal cover, which includes the step of ultrasonically bonding a first waterproof layer element, a main body element, and a second waterproof layer element using an ultrasonic bonding device to obtain an oral pharyngeal cover, wherein the main body element has a first bendable engagement portion, a hollow frame portion, and a second bendable engagement portion, with a shielded opening provided inside the hollow frame portion, the first bendable engagement portion and the second bendable engagement portion each provided on both sides of the hollow frame portion, and before ultrasonic bonding by the ultrasonic bonding device, the second waterproof layer element is positioned below the main body element, the first waterproof layer element is positioned above the main body element, and the first waterproof layer element and the second waterproof layer element each cover both sides of the shielded opening of the hollow frame portion.

[0008] In the above embodiment, when ultrasonic crimping is performed by an ultrasonic crimping device, the first waterproof layer element, the main body element, and the second waterproof layer element are all arranged on a convex mold element, and the convex mold element may be located within the shielded opening of the hollow frame portion.

[0009] Furthermore, in another aspect of the present invention, an oral pharyngeal cover is also provided, having a first foldable latching portion, a hollow frame portion, and a second foldable latching portion, with a shielded opening provided inside the hollow frame portion, and the first foldable latching portion and the second foldable latching portion each comprising a main body element provided on both sides of the hollow frame portion, a first waterproof layer element located above the main body element and shielding the shielded opening, and a second waterproof layer element located below the main body element and shielding the shielded opening, wherein the first waterproof layer element, the main body element, and the second waterproof layer element are ultrasonically pressed together by an ultrasonic pressing device.

[0010] In the above embodiment, a first extended portion may bulge out along the bulging direction in the region of the first waterproof layer element corresponding to the shielded opening, and a second extended portion may bulge out along the bulging direction in the region of the second waterproof layer element corresponding to the shielded opening.

[0011] Furthermore, in the above embodiment, the first waterproof layer element may be a medical-grade nonwoven fabric.

[0012] Furthermore, in the above embodiment, the second waterproof layer element may be a high-fiber meltblown nonwoven fabric.

[0013] Furthermore, in the above embodiment, at least one of the first bendable hooking portion, the hollow frame portion, and the second bendable hooking portion may be a wire wrapped in yarn. [Effects of the Invention]

[0014] Thus, the technical means provided in the present invention can achieve beneficial effects that cannot be achieved by the prior art. Specifically, unlike the conventional method of manufacturing oral and pharyngeal covers by sewing, one of the beneficial effects that can be achieved by the present invention is that it effectively improves the manufacturing efficiency of oral and pharyngeal covers, and furthermore, allows for wider application of oral and pharyngeal covers during oral treatment (or oral cleaning).

[0016] To enable those skilled in the art to easily understand the purpose, features, and effects of the present invention, the present invention will be described in detail through the following examples and accompanying drawings.

[0017] It should be noted that each step described in this invention may be executed sequentially, in reverse order, or in an appropriate order, such as by changing or omitting steps, during the control process. The statement in this invention that "the first step may be executed after the second step" can be expressed as "the first step is executed immediately after the second step is executed" or "the second step is executed first, then another step (for example, the third step) is executed, and then the first step is executed."

[0018] Also, in the content described in the present invention, terms such as "first", "second", and "third" are used to distinguish different elements, and are not intended to limit the elements themselves or indicate a specific order for the elements. In the descriptions below, the same element or step may be represented by the same reference numeral.

[0019] Refer to FIG. 1, which is a flowchart for explaining a method for manufacturing an oral and pharyngeal cover according to a first embodiment of the present invention. Taking FIG. 1 as an example, the method for manufacturing the oral and pharyngeal cover described in the present invention may include step S110, step S120, step S130, and step S140. Each step will be described in more detail below.

[0020] In some embodiments, taking FIG. 1 as an example, step S120 may be executed following step S110, step S130 may be executed following step S120, and step S140 may be executed following step S130.

[0021] In step S110, a second waterproof layer element is arranged. More specifically, by executing step S110, the second waterproof layer element is arranged in a specific region (for example, the crimping region of the ultrasonic crimping device described later). In some embodiments, the second waterproof layer element may be a finished product known to those skilled in the art. In a preferred embodiment, the second waterproof layer element may be a high-fiber melt-blown non-woven fabric, whereby the air permeability and / or waterproofness of the oral and pharyngeal cover can be improved by the characteristics of the high-fiber melt-blown non-woven fabric, and the practicality of the oral and pharyngeal cover can be improved. In some embodiments, those skilled in the art can arrange the second waterproof layer element using automated equipment (such as a robotic arm, etc.), thereby enhancing the manufacturing capacity of the oral and pharyngeal cover by the operation of the automated equipment, manufacturing even more oral and pharyngeal covers, and enabling the oral and pharyngeal cover to be more widely applied in the process of oral treatment (or oral cleaning).

[0022] In step S120, the main body element is positioned. More specifically, by performing step S120, the main body element is positioned above the second waterproof layer element. In some embodiments, those skilled in the art can position the main body element using automated equipment (e.g., a robotic arm), thereby increasing the production capacity of the oropharyngeal cover through the operation of the automated equipment, enabling the production of even more oropharyngeal covers and allowing for wider application of the oropharyngeal cover in the process of oral treatment (or oral cleaning).

[0023] In some embodiments, the main element may have a first bendable engagement portion, a hollow frame portion, and a second bendable engagement portion, with a shielded opening provided inside the hollow frame portion, and the first bendable engagement portion and the second bendable engagement portion provided on both sides of the hollow frame portion.

[0024] Taking Figure 2B, described later, as an example, the main element 200 may have a first bendable engagement portion 210, a hollow frame portion 220, and a second bendable engagement portion 230, wherein the first bendable engagement portion 210 is provided on one side (e.g., the left side) of the hollow frame portion 220, and the second bendable engagement portion 230 is provided on the other side (e.g., the right side) of the hollow frame portion 220. In some embodiments, those skilled in the art can improve the stability of use of the oropharyngeal cover (i.e., stability when the oropharyngeal cover is hooked onto the oral cavity of a dental patient to shield the oropharyngeal area) by adopting a symmetrical design and providing the first bendable engagement portion 210 and the second bendable engagement portion 230 on both sides (e.g., the left side and the right side opposite the left side) of the hollow frame portion 220, respectively. In some embodiments, as shown in Figure 2C later, the hollow frame portion 220 can be formed by using, for example, a circular or elliptical annular structure, thereby creating a shielded opening CO inside the hollow frame portion 220. This reduces the overall weight of the oral pharyngeal cover, alleviates discomfort when the oral pharyngeal cover is worn, and improves the user experience. The shielded opening CO is a communication area defined by the hollow frame portion 220, and the shielded opening CO can be shielded by a waterproof layer element such as cloth (for example, a first waterproof layer element and a second waterproof layer element). This prevents liquids such as saliva and water from inadvertently flowing into the hollow frame portion 220, thereby enhancing protection for the oral pharynx.

[0025] Furthermore, in some embodiments, the first bendable and deformable engaging portion 210 and the second bendable and deformable engaging portion 230 may be made of a material that can be deformed and bent when subjected to force (for example, a rigid plastic wire), and the hollow frame portion 220 may be made of a material that is elastic and deformable when subjected to force (for example, a rigid plastic wire), but is not limited thereto. In a preferred embodiment, at least one of the first bendable and deformable engaging portion 210, the hollow frame portion 220, and the second bendable and deformable engaging portion 230 may be, for example, a wire wrapped with yarn, but is not limited thereto. Taking Figure 4B, which will be described later, as an example, a person skilled in the art may form the main structure of the oral pharyngeal cover 50 (also called the main frame of the oral pharyngeal cover 50) by manufacturing the main element 200 of the oral pharyngeal cover 50 using a wire wrapped with yarn (for example, twisting two wires wrapped with yarn). Furthermore, since the yarn-wrapped wire is waterproof and suitable for contact with human skin, the construction of the yarn-wrapped wire can enhance the waterproofness and comfort of the oral pharyngeal cover, thereby improving its practicality and the user experience.

[0026] Furthermore, in some embodiments, the dimensions of the hollow frame portion 220 of the main element 200 depend on the dimensions of the oral pharynx of the dental patient in order to cover the oral pharynx of the dental patient, thereby forming an oral pharyngeal cover sufficient to shield the oral pharynx of the dental patient. More specifically, the dimensions of the hollow frame portion 220 of the main element 200 may be configured as an elliptical annular structure with a long axis of 80 mm and a short axis of 65 mm, and a shielded opening with a long axis of 70 mm and a short axis of 55 mm is formed inside the hollow frame portion 220, but is not limited to this. Also, the lengths of the first foldable engagement portion 210 and the second foldable engagement portion 230 may be set to 90 mm each, for example, but is not limited to this.

[0027] In step S130, the first waterproof layer element is positioned. More specifically, by performing step S130, the first waterproof layer element is positioned above the main element. In some embodiments, the first waterproof layer element may be a finished product known to those skilled in the art. In preferred embodiments, the first waterproof layer element may be, for example, 30 to 50 grams of medical nonwoven fabric, thereby improving the breathability and / or waterproofness of the oropharynx cover due to the properties of the medical nonwoven fabric, and improving the practicality of the oropharynx cover. In some embodiments, those skilled in the art may use automated equipment (e.g., a robotic arm) to position the first waterproof layer element, thereby increasing the production capacity of the oropharynx cover through the operation of the automated equipment, enabling the production of even more oropharynx covers and allowing for wider application of the oropharynx cover in the process of oral treatment (or oral cleaning).

[0028] By performing steps S110 to S130, before ultrasonically bonding each component of the oral pharyngeal cover with an ultrasonic bonding device (i.e., performing step S140), the relative positions and bonding relationships of each component of the oral pharyngeal cover are determined according to a specific arrangement order. As a result, the side structure of the oral pharyngeal cover to be manufactured thereafter can consist of a first waterproof layer element, a main body element, and a second waterproof layer element, in that order from top to bottom.

[0029] Taking Figure 2A, which will be described later, as an example, the second waterproof layer element 300 is positioned below the main body element 200, and the first waterproof layer element 100 is positioned above the main body element 200. The first waterproof layer element 100 and the second waterproof layer element 300 each cover both sides (i.e., the upper and lower sides) of the shielded opening of the hollow frame portion 220 of the main body element 200.

[0030] In step S140, ultrasonic crimping is performed using an ultrasonic crimping device. More specifically, by performing step S140, the ultrasonic crimping device performs ultrasonic crimping on the arranged first waterproof layer element, main body element and second waterproof layer element, thereby obtaining an oropharynx cover. In some embodiments, the ultrasonic crimping device may be an ultrasonic welding machine of various models and / or specifications known to those skilled in the art. Unlike conventional sewing methods for manufacturing oropharynx covers, the operation of the ultrasonic crimping device effectively improves the processing speed and production efficiency of oropharynx covers, thereby enabling the manufacture of more oropharynx covers and their wider use in oral treatment (or oral cleaning) procedures. Furthermore, oropharynx covers manufactured by conventional sewing methods are prone to fraying, causing them to lose their protective effect on the oropharynx. The ultrasonic crimping operation using the ultrasonic crimping device can also effectively improve the crimping stability between each element in the oropharynx cover, thereby preventing the oropharynx cover from losing its protective effect on the oropharynx and improving the practicality of the oropharynx cover.

[0031] Refer to Figure 2A, a schematic diagram illustrating the relative positions of the first waterproof layer element 100, the main body element 200, and the second waterproof layer element 300. More specifically, before the ultrasonic crimping device performs the ultrasonic crimping operation (i.e., performs step S140), the second waterproof layer element 300 is positioned below the main body element 200, and the first waterproof layer element 100 is positioned above the main body element 200, thereby enabling the manufacture of an oral pharyngeal cover in which the side structure is, from top to bottom, the first waterproof layer element 100, the main body element 200, and the second waterproof layer element 300.

[0032] In some embodiments, the first waterproof layer element 100 and the second waterproof layer element 300 are positioned above and below the main body element 200, respectively, covering both sides (i.e., the upper and lower sides) of the shielded opening in the hollow frame portion 220 of the main body element 200, thereby shielding the upper and lower parts of the shielded opening formed inside the hollow frame portion 220. In some other embodiments, the first waterproof layer element 100 and the second waterproof layer element 300 may be configured to completely cover the main body element 200.

[0033] Refer to Figure 2B, a schematic diagram illustrating an oropharyngeal cover 50 manufactured by the method for manufacturing an oropharyngeal cover shown in Figure 1. Using Figure 2B as an example, the oropharyngeal cover 50 comprises a first waterproof layer element 100, a main body element 200, and a second waterproof layer element (not shown in Figure 2B), the second waterproof layer element being located below the first waterproof layer element 100 and the main body element 200.

[0034] Refer to Figure 2C, a schematic diagram illustrating the structure of the main element 200. As an example, Figure 2C may include a first bendable latching portion 210, a hollow frame portion 220, and a second bendable latching portion 230. By using an elliptical annular structure, the hollow frame portion 220 can form a shielded opening CO inside the hollow frame portion 220, thereby reducing the overall weight of the oral pharyngeal cover, alleviating discomfort when the oral pharyngeal cover is worn, and improving the user experience. Furthermore, the shielded opening CO is a communication area defined by the hollow frame portion 220, and by shielding the shielded opening CO with a waterproof layer element such as cloth (e.g., a first waterproof layer element and a second waterproof layer element), it is possible to prevent liquids such as saliva and water from inadvertently flowing into the hollow frame portion 220, thereby enhancing protection to the oral pharynx.

[0035] The first foldable and deformable engaging portion 210 and the second foldable and deformable engaging portion 230 of the main element 200 can be deformed and folded when force is applied at the appropriate position, thereby allowing the oropharyngeal cover 50 to be adjusted according to the size and / or depth of the mouth of different dental patients and then hooked onto the dental patient's mouth, thus protecting the dental patient's oropharynx with the oropharyngeal cover 50.

[0036] The hollow frame portion 220 of the main element 200 uses, for example, an elliptical annular structure with a long axis of 80 mm and a short axis of 65 mm, thereby forming a shielded opening inside the hollow frame portion 220 with, for example, a long axis of 70 mm and a short axis of 55 mm. This shielded opening is then shielded by the first waterproof layer element 100 and the second waterproof layer element, preventing liquids such as saliva and water from inadvertently flowing into the oral pharynx of the dental patient, thus allowing the oral pharynx of the dental patient to be protected by the oral pharynx cover 50.

[0037] Refer to Figure 3, a flowchart illustrating a method for manufacturing an oral-pharyngeal cover according to a second embodiment of the present invention. Using Figure 3 as an example, the method for manufacturing an oral-pharyngeal cover according to the present invention may include steps S310, S320, S330, S340, and S350. Each step will be described in more detail below.

[0038] In some embodiments, taking Figure 3 as an example, step S320 may be performed following step S310, step S330 may be performed following step S320, step S340 may be performed following step S330, and step S350 may be performed following step S340.

[0039] In step S310, a convex mold element is positioned. More specifically, by performing step S310, the convex mold element is positioned in a specific area (for example, the crimping area of ​​an ultrasonic crimping device). In some embodiments, by fixing the convex mold element in the crimping area of ​​an ultrasonic crimping device, the oral pharyngeal cover shown in Figure 4B, described later, can be continuously manufactured using the convex mold element. In other words, after manufacturing the first oral pharyngeal cover by sequentially performing steps S310 to S350, the second oral pharyngeal cover can be manufactured by reusing the previously positioned and fixed convex mold element by subsequently performing step S320, thereby effectively improving the manufacturing efficiency of the oral pharyngeal cover. In some embodiments, the cross-sectional dimensions of the convex mold element are smaller than the dimensions of the hollow frame portion of the main element, so that the hollow frame portion of the main element can be fitted onto the convex mold element, and furthermore, the convex mold element can be positioned within the shielded opening of the hollow frame portion of the main element.

[0040] In step S320, the second waterproof layer element is positioned. More specifically, by performing step S320, the second waterproof layer element is positioned above the convex mold element.

[0041] In step S330, the main body element is positioned. More specifically, by executing step S330, the main body element is positioned above the second waterproof layer element, so that from top to bottom, the components are arranged as follows: main body element, second waterproof layer element, and convex mold element. Furthermore, by positioning the center point of the hollow frame portion of the main body element to coincide with the center point of the convex mold element, the hollow frame portion of the main body element can be fitted onto the convex mold element, and the convex mold element can be positioned within the shielded opening of the hollow frame portion of the main body element.

[0042] In step S340, the first waterproof layer element is positioned. More specifically, by executing step S340, the first waterproof layer element is positioned above the main body element, so that from top to bottom, the components are arranged in the order of the first waterproof layer element, the main body element, the second waterproof layer element, and the convex mold element.

[0043] In some embodiments, those skilled in the art can increase the production capacity of oropharyngeal covers by operating automated equipment (e.g., a robotic arm) to arrange the convex mold element, the second waterproof layer element, the main body element, and the first waterproof layer element, thereby enabling the production of even more oropharyngeal covers and allowing for wider application of oropharyngeal covers in the process of oral treatment (or oral cleaning).

[0044] In step S350, ultrasonic bonding is performed using an ultrasonic bonding device. More specifically, by performing step S350, the ultrasonic bonding device ultrasonically bonds the first waterproof layer element, the main body element, and the second waterproof layer element, which are arranged on the convex mold element, to obtain the oral pharyngeal cover shown in Figure 4B, which will be described later. In some embodiments, the ultrasonic bonding device may be an ultrasonic welding machine of various models and / or specifications known to those skilled in the art.

[0045] The first waterproof layer element, the main body element, and the second waterproof layer element are placed above the convex mold element and then ultrasonically bonded by an ultrasonic bonding device (i.e., step S350 is performed). As a result, more material for the first and second waterproof layer elements is used during the ultrasonic bonding process to manufacture the oropharynx cover. Consequently, the first and second waterproof layer elements of the manufactured oropharynx cover have a first extension and a second extension, respectively (i.e., the first and second waterproof layer elements are plastic). This allows the dimensions of the hollow frame portion of the main body element of the oropharynx cover to be finely adjusted according to the oropharynx of the dental patient, enabling the use of oropharynx covers with the same manufacturing specifications on a wider range of different dental patients' oropharynxes.

[0046] Refer to Figure 4A, a schematic diagram illustrating the relative positions of the first waterproof layer element 100, the main body element 200, the second waterproof layer element 300, and the convex mold element 400. More specifically, before ultrasonic bonding by the ultrasonic bonding device, the second waterproof layer element 300 is positioned above the convex mold element 400, the main body element 200 is positioned above the second waterproof layer element 300, and the first waterproof layer element 100 is positioned above the main body element 200. This allows the ultrasonic bonding device to manufacture an oral pharyngeal cover in which the side structure is arranged from top to bottom as the first waterproof layer element 100, the main body element 200, and the second waterproof layer element 300.

[0047] Refer to Figure 4B, a schematic diagram illustrating the oral pharyngeal cover 50 manufactured by the method for manufacturing the oral pharyngeal cover shown in Figure 3. Using Figure 4B as an example, the main body element 200 of the oral pharyngeal cover 50 is made of wire wrapped in yarn (for example, by twisting wire wrapped from two strands of yarn). Furthermore, in the region of the first waterproof layer element 100 of the oral pharyngeal cover 50 corresponding to the shielded opening of the hollow frame portion 220 of the main body element 200, the first extending portion 110 bulges out along the bulging direction (for example, the direction opposite to the position of the convex mold element, i.e., upward), and in the region of the second waterproof layer element (not shown in Figure 4B) of the oral pharyngeal cover 50 corresponding to the shielded opening of the hollow frame portion 220 of the main body element 200, the bulging direction (for example, the direction opposite to the position of the convex mold element, i.e., upward) The second extending portion is bulged along this, which provides plasticity to the first waterproof layer element 100 and the second waterproof layer element of the oral pharyngeal cover 50. This makes it easier to fine-tune the dimensions of the hollow frame portion 220 of the main element 200 according to the oral pharyngeal area of ​​the dental patient (for example, by applying a moderate outward expansion force to enlarge the dimensions of the hollow frame portion 220 of the main element 200), allowing oral pharyngeal covers of the same manufacturing specifications to be used more widely for different oral pharyngeal areas of dental patients.

[0048] Refer to Figure 5, a schematic diagram illustrating the usage of the oral pharyngeal cover 50. Using Figure 5 as an example, during oral treatment (or oral cleaning), the dentist first hooks the oral pharyngeal cover 50 onto the patient's mouth in an appropriate manner to protect the patient's oral pharynx with the oral pharyngeal cover 50. This prevents the patient from choking due to inadvertently inhaling oral fluids and / or from aspirating foreign objects such as extracted teeth or other dental instruments, thereby improving the user experience and ensuring that oral treatment (or oral cleaning) can be performed smoothly.

[0049] Although the present invention has been further described based on the above embodiments and accompanying drawings, those skilled in the art can make many modifications and changes without departing from the claims and spirit of the present invention. Accordingly, the scope of protection of the present invention is as defined in the claims and is not limited to the embodiments disclosed in the specification. [Explanation of symbols]
