Abstract
Description
Technical Field
[0001] This invention relates to a method for manufacturing a mask and a mask product, and more particularly to a method for manufacturing an oropharyngeal mask and an oropharyngeal mask. Background Technology
[0002] During oral treatment (or oral cleaning), if people accidentally inhale liquids such as saliva or water, it can easily cause discomfort such as choking. In practice, although saliva suction tubes are used to remove liquids from the mouth, people who habitually breathe through their mouths, those who have undergone oral tumor surgery, or those with dementia may still accidentally inhale liquids from their mouths, causing choking, discomfort, or requiring immediate interruption of treatment, and may even lead to aspiration pneumonia.
[0003] Furthermore, during oral treatment (such as tooth extraction), dental patients may accidentally swallow foreign objects such as extracted teeth or other dental instruments, which may cause them discomfort or require immediate interruption of the treatment, thus triggering an emergency and even threatening the safety of dental patients.
[0004] In recent years, to avoid the aforementioned situation, dentists have placed a mask (i.e., an oropharyngeal mask) in the patient's oropharynx (i.e., the location of the oropharyngeal airway inside the patient's mouth) to prevent the patient from accidentally inhaling liquids such as saliva or water, or foreign objects such as extracted teeth or other dental instruments during oral treatment (or oral cleaning). Summary of the Invention
[0005] However, the existing design of oropharyngeal masks mainly considers the protection of the oropharynx, but does not take into account the production efficiency of oropharyngeal masks. Under these circumstances, oropharyngeal masks cannot be mass-produced in a short period of time, which leads to the high price of oropharyngeal masks, and thus prevents them from being used more widely in oral treatment (or oral cleaning) processes.
[0006] In view of this, how to solve the above-mentioned problems encountered by existing oropharyngeal masks and effectively improve the production efficiency of oropharyngeal masks has become an urgent problem that this technical field hopes to solve.
[0007] To address the aforementioned problems, this application provides a method for manufacturing an oropharyngeal mask, the method comprising the following steps: ultrasonically pressing a first waterproof layer element, a body element, and a second waterproof layer element using an ultrasonic pressing device to obtain an oropharyngeal mask; wherein the body element includes a first flexible deformable hanging part, a hollow frame part, and a second flexible deformable hanging part, the inner side of the hollow frame part is provided with an opening to be blocked, and the first flexible deformable hanging part and the second flexible deformable hanging part are respectively disposed on both sides of the hollow frame part; and wherein, before ultrasonic pressing, the second waterproof layer element is placed below the body element, the first waterproof layer element is placed above the body element, and the first and second waterproof layer elements respectively cover both sides of the opening to be blocked in the hollow frame part.
[0008] In some embodiments, when the ultrasonic pressing device performs ultrasonic pressing, the first waterproof layer element, the body element, and the second waterproof layer element are placed together on the raised mold element, and the raised mold element is located in the opening to be covered in the hollow frame portion.
[0009] In addition, this application also provides an oropharyngeal mask, comprising: a body element including a first flexible deformable hanging part, a hollow frame part and a second flexible deformable hanging part, wherein the inner side of the hollow frame part is provided with an opening to be covered, and the first flexible deformable hanging part and the second flexible deformable hanging part are respectively disposed on both sides of the hollow frame part; a first waterproof layer element located above the body element and covering the opening to be covered; and a second waterproof layer element located below the body element and covering the opening to be covered; wherein the first waterproof layer element, the body element and the second waterproof layer element are ultrasonically pressed together by an ultrasonic pressing device.
[0010] In some embodiments, the area of the first waterproof layer element corresponding to the opening to be covered has a first extension protruding along the protrusion direction, and the area of the second waterproof layer element corresponding to the opening to be covered has a second extension protruding along the protrusion direction.
[0011] In some embodiments, the first waterproof layer element is a medical nonwoven fabric.
[0012] In some embodiments, the second waterproof layer element is a high-fiber meltblown nonwoven fabric.
[0013] In some embodiments, at least one of the first flexible deformable hanging part, the hollow frame part, and the second flexible deformable hanging part is a hairline.
[0014] In this way, the technical means provided in this application can achieve advantageous effects that cannot be achieved by existing technologies. Specifically, unlike the existing method of manufacturing oropharyngeal masks by sewing, one advantage of this application is that it can effectively improve the production efficiency of oropharyngeal masks, thereby enabling oropharyngeal masks to be used more widely in the process of oral treatment (or oral cleaning).

[0036] This application will be described in detail through the embodiments described below and the accompanying drawings, in order to help those skilled in the art understand the purpose, features and effects of this application.
[0037] It should be noted that the various steps described in this application may be performed sequentially, in reverse order, or by appropriately changing or skipping the order during control processing. It should be noted that "the first step may be performed after the second step" as described in this application may mean "the first step is performed directly after the second step is performed" and / or "other steps (e.g., the third step) are performed after the second step is performed, and then the first step is performed."
[0038] Furthermore, it should be noted that in the description of this application, terms such as "first," "second," and "third" are used to distinguish between elements, rather than to limit the elements themselves or indicate a specific order of elements. It should also be noted that in the description below, the same elements or steps may be represented by the same numbering.
[0039] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a method for manufacturing an oropharyngeal mask according to a first embodiment of this application. Figure 1 For example, the method for manufacturing an oropharyngeal mask described in this application may include steps S110, S120, S130, and S140. Each step will be described in more detail below.
[0040] In some embodiments, with Figure 1 For example, step S120 can be executed after step S110, step S130 can be executed after step S120, and step S140 can be executed after step S130.
[0041] In step S110, a second waterproof layer element is placed. More specifically, by performing step S110, the second waterproof layer element is placed on a specific area (e.g., the pressing area of the ultrasonic pressing 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 meltblown nonwoven fabric, so as to improve the breathability and / or waterproofness of the oropharyngeal mask by virtue of the properties of the high-fiber meltblown nonwoven fabric, thereby improving the practicality of the oropharyngeal mask. In some embodiments, those skilled in the art may use automated equipment (e.g., robotic arms, etc.) to place the second waterproof layer element, so as to increase the production capacity of the oropharyngeal mask by the operation of the automated equipment, thereby manufacturing a larger number of oropharyngeal masks so that the oropharyngeal mask can be more widely used in the process of oral treatment (or oral cleaning).
[0042] In step S120, the body element is placed. More specifically, by performing step S120, the body element is placed on top of the second waterproof layer element. In some embodiments, those skilled in the art can employ automated equipment (e.g., robotic arms) to place the body element, thereby increasing the production capacity of the oropharyngeal mask by operating the automated equipment, and thus manufacturing a larger number of oropharyngeal masks so that they can be more widely used in oral treatment (or oral cleaning) procedures.
[0043] In some embodiments, the body element may include a first flexible deformable hanging part, a hollow frame part, and a second flexible deformable hanging part, wherein the inner side of the hollow frame part is provided with an opening to be blocked, and the first flexible deformable hanging part and the second flexible deformable hanging part are respectively disposed on both sides of the hollow frame part.
[0044] The following will be discussed Figure 2B For example, the body element 200 may include a first flexible deformable hanging part 210, a hollow frame part 220, and a second flexible deformable hanging part 230, wherein the first flexible deformable hanging part 210 is disposed on one side (e.g., the left side) of the hollow frame part 220, and the second flexible deformable hanging part 230 is disposed on the other side (e.g., the right side) of the hollow frame part 220. In some embodiments, those skilled in the art may employ a symmetrical design to respectively dispose the first flexible deformable hanging part 210 and the second flexible deformable hanging part 230 on both sides (e.g., the left side and the right side opposite the left side) of the hollow frame part 220, thereby improving the stability of the oropharyngeal mask in use (i.e., the stability when the oropharyngeal mask is worn on the mouth of a dental patient to cover the oropharynx). Furthermore, in some embodiments, as described later... Figure 2CFor example, the hollow frame portion 220 can adopt a circular or elliptical annular structure to form an opening CO to be blocked on the inner side of the hollow frame portion 220, thereby reducing the overall weight of the oropharyngeal mask and reducing discomfort, thus improving the user experience; furthermore, the opening CO to be blocked is a connected area defined by the hollow frame portion 220, and the opening CO to be blocked can be blocked by a waterproof layer element such as cloth (e.g., a first waterproof layer element and a second waterproof layer element), thereby preventing liquids such as saliva or water from accidentally flowing into the hollow frame portion 220, thereby improving the protection of the oropharynx.
[0045] Furthermore, in some embodiments, the first flexible deformable hanging portion 210 and the second flexible deformable hanging portion 230 may be components made of a material that can be bent under stress (e.g., rigid plastic wire), while the hollow frame portion 220 may be a component made of an elastic and deformable material (e.g., rigid plastic wire), but are not limited thereto. In a preferred embodiment, at least one of the first flexible deformable hanging portion 210, the hollow frame portion 220, and the second flexible deformable hanging portion 230 may be, for example, a pipe cleaner, but is not limited thereto. (The following will be discussed...) Figure 4B For example, those skilled in the art can use capillary threads (e.g., winding two capillary threads together) to prepare the body element 200 of the oropharyngeal mask 50 to form the main structure of the oropharyngeal mask 50 (or the main frame of the oropharyngeal mask 50). Furthermore, since capillary threads are waterproof and suitable for contact with human skin, the configuration of capillary threads can improve the waterproofness and wearing comfort of the oropharyngeal mask, thereby enhancing its practicality and improving the user experience.
[0046] In some embodiments, the size of the hollow frame portion 220 of the body element 200 is determined by the size of the dental patient's oropharynx, so as to cover the dental patient's oropharynx and thus form an oropharyngeal mask sufficient to cover the dental patient's oropharynx. More specifically, the size of the hollow frame portion 220 of the body element 200 can be configured as, for example, an elliptical ring structure with a major axis of 80 mm and a minor axis of 65 mm, and an opening to be covered is formed on the inner side of the hollow frame portion 220, for example, with a major axis of 70 mm and a minor axis of 55 mm, but is not limited thereto. Furthermore, the lengths of the first flexible deformable hanging portion 210 and the second flexible deformable hanging portion 230 can each be configured as, for example, 90 mm, but are not limited thereto.
[0047] In step S130, a first waterproof layer element is placed. More specifically, by performing step S130, the first waterproof layer element is placed on top of the body element. In some embodiments, the first waterproof layer element may be a finished product known to those skilled in the art. In a preferred embodiment, the first waterproof layer element may be, for example, 30 to 50 grams of medical nonwoven fabric, in order to improve the breathability and / or waterproofness of the oropharyngeal mask by virtue of the properties of the medical nonwoven fabric, thereby improving the practicality of the oropharyngeal mask. In some embodiments, those skilled in the art may use automated equipment (e.g., robotic arms) to place the first waterproof layer element, so as to increase the production capacity of the oropharyngeal mask by operating the automated equipment, thereby manufacturing a larger number of oropharyngeal masks so that the oropharyngeal mask can be more widely used in the process of oral treatment (or oral cleaning).
[0048] By performing steps S110 to S130, the relative positions and pressing relationships between the various components of the oropharyngeal mask can be determined according to a specific placement order before ultrasonic pressing is performed by the ultrasonic pressing device (i.e., performing step S140), so that the side structure of the oropharyngeal mask manufactured subsequently can be sequentially arranged from top to bottom as a first waterproof layer element, a body element, and a second waterproof layer element.
[0049] The following will be discussed Figure 2A For example, the second waterproof layer element 300 is placed below the body element 200, while the first waterproof layer element 100 is placed above the body element 200, and the first waterproof layer element 100 and the second waterproof layer element 300 respectively cover both sides (i.e., the upper and lower sides) of the opening to be covered in the hollow frame portion 220 of the body element 200.
[0050] In step S140, ultrasonic bonding is performed using an ultrasonic bonding device. More specifically, by performing step S140, the ultrasonic bonding device ultrasonically bonds the placed first waterproof layer element, body element, and second waterproof layer element to obtain an oropharyngeal mask. In some embodiments, the ultrasonic bonding device can be various models and / or specifications of ultrasonic welding machines known to those skilled in the art. Unlike existing methods of manufacturing oropharyngeal masks using sewing, the operation of the ultrasonic bonding device can effectively increase the processing speed, thereby effectively increasing the production efficiency of oropharyngeal masks and manufacturing a larger number of oropharyngeal masks, so that the oropharyngeal masks can be more widely used in oral treatment (or oral cleaning) processes. In addition, since oropharyngeal masks manufactured by existing sewing methods are prone to unraveling, resulting in the oropharyngeal mask losing its protective effect on the oropharynx, the ultrasonic bonding operation using the ultrasonic bonding device can also effectively improve the bonding stability between the various components in the oropharyngeal mask, thereby preventing the oropharyngeal mask from losing its protective effect on the oropharynx and improving the practicality of the oropharyngeal mask.
[0051] Please refer to Figure 2A , Figure 2A This is a schematic diagram illustrating the relative positions of the first waterproof layer element 100, the body element 200, and the second waterproof layer element 300. More specifically, before the ultrasonic pressing operation (i.e., performing step S140) is performed by the ultrasonic pressing device, the second waterproof layer element 300 is placed below the body element 200, and the first waterproof layer element 100 is placed above the body element 200, so as to create a mouthpiece with the side structure consisting of the first waterproof layer element 100, the body element 200, and the second waterproof layer element 300 in that order from top to bottom.
[0052] In some embodiments, the first waterproof layer element 100 and the second waterproof layer element 300 are located above and below the body element 200, respectively, and respectively cover both sides (i.e., the upper and lower sides) of the opening to be covered in the hollow frame portion 220 of the body element 200, so as to cover the opening above and below the opening to be covered formed on the inner side of the hollow frame portion 220, respectively. Furthermore, in other embodiments, the first waterproof layer element 100 and the second waterproof layer element 300 may also be configured to completely cover the body element 200.
[0053] Please refer to Figure 2B , Figure 2B It is used to illustrate, for example Figure 1 This diagram illustrates an oropharyngeal mask 50 manufactured using a method for manufacturing an oropharyngeal mask. Figure 2B For example, the oropharyngeal mask 50 includes a first waterproof layer element 100, a body element 200, and a second waterproof layer element ( Figure 2B (Not shown), wherein the second waterproof layer element is located below the first waterproof layer element 100 and the body element 200.
[0054] Please refer to Figure 2C , Figure 2C This is a structural schematic diagram used to illustrate the main body component 200. Figure 2C For example, the body element 200 may include a first flexible and deformable hanging part 210, a hollow frame part 220, and a second flexible and deformable hanging part 230. The hollow frame part 220 may adopt an elliptical ring structure so that an opening CO to be blocked is formed on the inner side of the hollow frame part 220, thereby reducing the overall weight of the oropharyngeal mask and reducing the discomfort of the oropharyngeal mask to improve the user experience. Furthermore, the opening CO to be blocked is a connected area defined by the hollow frame part 220, and the opening CO to be blocked can be blocked by a waterproof layer element such as cloth (e.g., a first waterproof layer element and a second waterproof layer element), thereby preventing liquids such as saliva or water from accidentally flowing into the hollow frame part 220, thereby improving the protection of the oropharynx.
[0055] The first flexible deformable hanging part 210 and the second flexible deformable hanging part 230 of the main body element 200 can be bent by force at appropriate positions so that the oropharyngeal mask 50 can be properly adjusted and worn on the oral cavity of the dental patient according to the different mouth diameter and / or oral cavity depth, thereby protecting the dental patient's oropharynx by means of the oropharyngeal mask 50.
[0056] The hollow frame portion 220 of the body element 200 adopts an elliptical ring structure with a major axis of 80 mm and a minor axis of 65 mm, so that an opening to be blocked is formed on the inner side of the hollow frame portion 220, with a major axis of 70 mm and a minor axis of 55 mm. The opening to be blocked can be blocked by the first waterproof layer element 100 and the second waterproof layer element, thereby preventing liquids such as saliva or water from accidentally flowing into the oropharynx of the dental patient, so as to protect the oropharynx of the dental patient by means of the oropharyngeal mask 50.
[0057] Please refer to Figure 3 , Figure 3 This is a flowchart illustrating a method for manufacturing an oropharyngeal mask according to a second embodiment of this application. Figure 3 For example, the method for manufacturing an oropharyngeal mask described in this application may include steps S310, S320, S330, S340, and S350. Each step will be described in more detail below.
[0058] In some embodiments, with Figure 3 For example, step S320 can be executed after step S310, step S330 can be executed after step S320, step S340 can be executed after step S330, and step S350 can be executed after step S340.
[0059] In step S310, a protruding mold element is placed. More specifically, by performing step S310, the protruding mold element is placed on a specific area (e.g., the pressing area of an ultrasonic pressing device). In some embodiments, the protruding mold element may be fixedly placed on the pressing area of the ultrasonic pressing device so as to continuously manufacture the components described later using the protruding mold element. Figure 4BThe oropharyngeal mask. In other words, after the first oropharyngeal mask is manufactured by sequentially performing steps S310 to S350, step S320 can be performed subsequently to manufacture a second oropharyngeal mask using the previously placed and fixed protruding mold element, thereby effectively improving the production efficiency of the oropharyngeal mask. In some embodiments, the cross-sectional dimension of the protruding mold element is smaller than the dimension of the hollow frame portion of the body element, so that the hollow frame portion of the body element can be fitted onto the protruding mold element, thereby positioning the protruding mold element within the opening to be blocked in the hollow frame portion of the body element.
[0060] In step S320, a second waterproof layer element is placed. More specifically, by performing step S320, the second waterproof layer element is placed on top of the raised mold element.
[0061] In step S330, the body element is placed. More specifically, by performing step S330, the body element is placed above the second waterproof layer element, so as to form a structure consisting of the body element, the second waterproof layer element, and the raised mold element in that order from top to bottom. Furthermore, the center point of the hollow frame portion of the body element is aligned with the center point of the raised mold element, so that the hollow frame portion of the body element can be fitted onto the raised mold element, thereby positioning the raised mold element within the opening to be covered in the hollow frame portion of the body element.
[0062] In step S340, a first waterproof layer element is placed. More specifically, by performing step S340, the first waterproof layer element is placed on top of the body element to form a sequence from top to bottom consisting of a first waterproof layer element, a body element, a second waterproof layer element, and a raised mold element.
[0063] In some embodiments, those skilled in the art may use automated equipment (such as robotic arms) to place the protruding mold element, the second waterproof layer element, the body element, and the first waterproof layer element respectively, so as to increase the production capacity of the oropharyngeal mask by operating the automated equipment, thereby manufacturing a larger number of oropharyngeal masks so that the oropharyngeal mask can be more widely used in the process of oral treatment (or oral cleaning).
[0064] In step S350, ultrasonic pressing is performed using an ultrasonic pressing device. More specifically, by executing step S350, the ultrasonic pressing device ultrasonically presses the first waterproof layer element, the body element, and the second waterproof layer element placed on the protruding mold element to obtain the result described later. Figure 4B Oropharyngeal mask. In some embodiments, the ultrasonic pressing device may be an ultrasonic welding machine of various models and / or specifications known to those skilled in the art.
[0065] Since the first waterproof layer element, the body element, and the second waterproof layer element are placed above the raised mold element and then ultrasonically pressed using an ultrasonic pressing device (i.e., step S350 is executed), more material from the first and second waterproof layer elements is used to manufacture the oropharyngeal mask during the ultrasonic pressing process. As a result, the first and second waterproof layer elements of the manufactured oropharyngeal mask each have a first extension and a second extension (i.e., the first and second waterproof layer elements are malleable). This allows the hollow frame portion of the body element of the oropharyngeal mask to be finely adjusted according to the oropharynx of the dental patient, thereby enabling oropharyngeal masks of the same manufacturing specifications to be more widely used on the oropharynx of different dental patients.
[0066] Please refer to Figure 4A , Figure 4A This is a schematic diagram illustrating the relative positions of the first waterproof layer element 100, the body element 200, the second waterproof layer element 300, and the raised mold element 400. More specifically, before ultrasonic pressing is performed by the ultrasonic pressing equipment, the second waterproof layer element 300 is placed above the raised mold element 400, the body element 200 is placed above the second waterproof layer element 300, and the first waterproof layer element 100 is placed above the body element 200, so as to manufacture a pharyngeal mask with the side structure consisting of the first waterproof layer element 100, the body element 200, and the second waterproof layer element 300 in that order from top to bottom by means of the ultrasonic pressing equipment.
[0067] Please refer to Figure 4B , Figure 4B It is used to illustrate, for example Figure 3 This diagram illustrates an oropharyngeal mask 50 manufactured using a method for manufacturing an oropharyngeal mask. Figure 4B For example, the body element 200 of the oropharyngeal mask 50 is made of capillary wire (for example, two capillary wires are wound together). Furthermore, the area of the first waterproof layer element 100 of the oropharyngeal mask 50 corresponding to the opening to be blocked in the hollow frame portion 220 of the body element 200 protrudes along the protrusion direction (for example, the direction opposite to the position of the protruding mold element, i.e., upwards), while the second waterproof layer element of the oropharyngeal mask 50 ( Figure 4B(Not shown) The area corresponding to the opening to be blocked in the hollow frame portion 220 of the body element 200 protrudes a second extension along the protrusion direction (e.g., the direction opposite to the position of the protruding mold element, i.e., upward), thereby making the first waterproof layer element 100 and the second waterproof layer element of the oropharyngeal mask 50 malleable so as to finely adjust the size of the hollow frame portion 220 of the body element 200 according to the oropharynx of the dental patient (e.g., apply an outward expansion force appropriately to increase the size of the hollow frame portion 220 of the body element 200), so that oropharyngeal masks of the same manufacturing specifications can be more widely applied to the oropharynx of different dental patients.
[0068] Please refer to Figure 5 , Figure 5 This is a schematic diagram illustrating the usage of the oropharyngeal mask 50. Figure 5 For example, during oral treatment (or oral cleaning), the dentist can first attach the oropharyngeal mask 50 to the dental patient's mouth in an appropriate manner. The oropharyngeal mask 50 can then protect the dental patient's oropharynx and prevent the dental patient from accidentally inhaling liquids in the mouth, causing choking and / or swallowing foreign objects such as extracted teeth or other dental instruments, which could lead to emergencies. This improves the user experience and ensures that oral treatment (or oral cleaning) can be carried out smoothly.
[0069] This application has been further described through the above embodiments and accompanying drawings, but those skilled in the art can still make many modifications and variations without departing from the scope and spirit set forth in the claims. Therefore, the scope of protection of this application should still be determined by the claims and should not be limited by the embodiments disclosed in the specification.
