Abstract
Description
Technical Field
[0001] This utility model relates to ventilation therapy equipment, specifically to a breathing mask. Furthermore, this utility model also relates to a ventilation therapy device including the breathing mask. Background Technology
[0002] Non-invasive positive pressure ventilation (NPPV) technology has been widely used to treat diseases such as obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD). This avoids surgically inserting tubes into the patient's airway, instead using a blower to deliver continuous or variable pressure ventilation through a ventilation tube and a face mask worn on the patient's face. This pressure support therapy is also commonly used for conditions such as obstructive sleep hypoventilation, upper airway resistance syndrome (UARS), or congestive heart failure.
[0003] Respiratory masks used for positive pressure ventilation include oronasal masks, nasal masks, nasal pillow masks, and full-face masks. In use, the mask is worn on the patient's face to supply breathing gas generated by the ventilation equipment to the patient's airway. To ensure a stable supply of breathing gas to the patient's airway, some masks are equipped with bony arms that are fixed or adjustable to the mask body (cup or frame) to support the patient's forehead or cheeks during use. However, the bony arms of existing masks are not suitable for different usage scenarios. For example, when a patient is reading, a mask without forehead support is needed; while when a patient is sleeping, a mask with forehead support is more conducive to stable wearing. Therefore, to meet the needs of different usage scenarios, different structural forms of respiratory masks are required, which increases treatment and usage costs. Utility Model Content
[0004] The purpose of this invention is to overcome the problem that existing breathing masks cannot be adapted to different usage scenarios, and to provide a breathing mask that can be configured to support the patient's forehead or both cheeks in different usage scenarios, thereby eliminating the need to replace the entire breathing mask and reducing treatment and usage costs.
[0005] To achieve the above objectives, this utility model provides a breathing mask, including a mask body, the mask body having a central interface for detachably connecting a central bone beam arm and a left interface and a right interface for detachably connecting a left bone beam arm and a right bone beam arm, respectively, so as to allow a user to selectively configure the breathing mask to a first use state suitable for supporting the forehead with the central bone beam arm or a second use state suitable for supporting both cheeks with the left and right bone beam arms.

[0007] Preferably, the mask body has a ventilation port for connecting to a ventilation pipe, and headband connecting portions for connecting a headband are formed on both sides of the ventilation port.
[0008] Preferably, at least one of the middle interface, the left interface, and the right interface is configured to be detachably connected to the corresponding middle bone beam arm, the left bone beam arm, and the right bone beam arm via a snap fastener, pin, hinge, adhesive, or magnetic attraction.
[0009] Preferably, in the first usage state, the angle between the direction of the force applied by the mask body to the intermediate bone beam arm and the direction of the force applied when the intermediate bone beam arm is removed from the mask body is not less than 90°; and / or, in the second usage state, the angle between the direction of the force applied by the mask body to the left and right bone beam arms and the direction of the force applied when the left and right bone beam arms are removed from the mask body is not less than 90°.
[0010] Preferably, at least one of the middle interface, the left interface, and the right interface is configured to have a snap-fit protrusion and / or a snap-fit groove, and the corresponding middle bone beam arm, the left bone beam arm, and / or the right bone beam arm have a mating groove and / or a mating protrusion for engaging with the snap-fit protrusion and / or the snap-fit groove.
[0011] Preferably, at least one of the intermediate interface, the left interface, and the right interface is configured to have a mounting slot for inserting and connecting the corresponding intermediate bone beam arm, the left bone beam arm, and the right bone beam arm, and the intermediate interface, the left interface, and / or the right interface, or the corresponding intermediate bone beam arm, the left bone beam arm, and the right bone beam arm have a limiting hole or a limiting protrusion for defining the insertion position.
[0012] Preferably, the breathing mask has a positioning pin, and positioning holes are formed on at least one of the middle interface, the left interface and / or the right interface, as well as on the corresponding middle rib arm, the left rib arm and the right rib arm, so as to configure it to the first use state or the second use state by allowing the positioning pin to pass through the positioning hole.
[0013] Preferably, the breathing mask includes a fastener having a locking structure for snapping onto the mask body, and the positioning pin is disposed on the fastener.
[0014] A second aspect of this invention provides a ventilation therapy device including the above-described breathing mask.
[0015] Through the above technical solution, the breathing mask of this utility model can selectively connect a middle bone beam arm to the middle interface of the mask body or connect a left bone beam arm and a right bone beam arm to the left and right interfaces, so as to present a first usage state in which the middle bone beam arm supports the user's forehead and a second usage state in which the left and right bone beam arms support the user's cheeks in different usage scenarios, without the need to equip different breathing masks for different scenarios, thereby reducing treatment and usage costs.

[0030] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0031] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to the upper, lower, left, and right as shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself.
[0032] As mentioned earlier, breathing masks come in various types and forms. This invention provides a breathing mask capable of being configured with different bony arms according to the usage scenario, and its mask body can be configured in different forms. For example, the mask body may include a pad for sealing contact with the patient's face and a rigid or semi-rigid frame, whereby the interfaces for connecting the bony arms can be located on the frame. In a breathing mask without a frame, the mask body can be formed as a one-piece pad (or "cup"), in which case the interfaces for connecting the bony arms are located on the pad.
[0033] In addition, breathing masks typically include one or more headbands for securing the mask to the patient's head. These headbands can be connected to the bony arm or directly to the mask body. When the mask body has a headband connector for attaching the headbands, the headband connected to this connector generally refers to the lower headband that extends from below the patient's ears during use.
[0034] Reference Figure 1 and Figure 2As shown, one aspect of this utility model provides a breathing mask, including a mask body 1, which has a central interface 12 for detachably connecting a central bone beam arm 2 and a left interface 13 and a right interface 14 for detachably connecting a left bone beam arm 3 and a right bone beam arm 4, respectively, so as to allow a user to selectively configure the breathing mask to a first use state suitable for supporting the forehead with the central bone beam arm 2 or a second use state suitable for supporting both cheeks with the left bone beam arm 3 and the right bone beam arm 4.
[0035] Therefore, as Figure 1 As shown, when the patient is sleeping, the middle bony arm 2 can be connected to the middle interface 12 of the mask body 1, while the left bony arm 3 and right bony arm 4 are removed. This allows the middle bony arm 2 to support the patient's forehead, facilitating stable wearing of the breathing mask during sleep without affecting the patient's ability to turn over. Figure 2 and Figure 3 As shown, when the patient is reading, the middle bone beam arm 2 can be removed, and the left bone beam arm 3 and the right bone beam arm 4 can be connected to the left interface 13 and the right interface 14 of the mask body 1, respectively, so that the left bone beam arm 3 and the right bone beam arm 4 can support the patient's cheeks and avoid the middle bone beam arm 2 from obstructing the patient's vision.
[0036] Therefore, the breathing mask of this utility model allows for selective connection of a middle bone beam arm 2 to the middle interface 12 of the mask body 1, or connection of a left bone beam arm 3 and a right bone beam arm 4 to the left interface 13 and the right interface 14, so as to present a first usage state in which the middle bone beam arm 2 supports the user's forehead and a second usage state in which the left bone beam arm 3 and the right bone beam arm 4 support the user's cheeks in different usage scenarios, without the need to equip different breathing masks for different scenarios. This reduces the treatment and usage costs compared to the traditional method of configuring a single bone beam arm.
[0037] It is understood that although this utility model describes a second usage state in which the left bony arm 3 and the right bony arm 4 are simultaneously connected to the mask body 1, in some special circumstances, the provided breathing mask may have other usage states, such as using only one of the left bony arm 3 and the right bony arm 4, or using the middle bony arm 2 and one of the left bony arm 3 and the right bony arm 4 simultaneously. Therefore, the breathing mask provided by this utility model has a wider range of applicability in various scenarios.
[0038] The middle skeletal beam arm 2, the left skeletal beam arm 3, and the right skeletal beam arm 4 can be made of relatively hard materials such as PP, PC, and nylon, or they can be composites of these materials with silicone, foam, gel, fabric, etc. Their molding methods include, but are not limited to, injection molding, cutting, or 3D printing, or they can be formed by combining multiple different components together through assembly, bonding, etc.
[0039] Typically, such as Figure 4 As shown, the mask body 1 can be configured with a generally triangular frontal shape. To ensure wearing comfort, the mask body 1 can have an axisymmetric structure, with its axis of symmetry aligned with the patient's philtrum when worn. The central interface 12 can be located at the top of the mask body 1 and on the axis of symmetry, while the left interface 13 and right interface 14 are symmetrically located on the two sides of the mask body 1. Therefore, the central bony arm 2, as well as the left bony arm 3 and right bony arm 4, can be configured with relatively short extension lengths, which facilitates stable transmission of support force.
[0040] In addition, such as Figures 1 to 5 As shown, the mask body 1 may have an air inlet 11 for connecting to a ventilation line, allowing the cavity formed when the mask body 1 is fastened to the patient's face to be sealed via a bend connected to the air inlet 11, thereby receiving respiratory gas supplied by a respiratory supply device (such as a ventilator). On both sides of the air inlet 11, the mask body 1 may also have headband connecting portions 15 for connecting a headband, so as to connect to a lower headband extending from below the patient's ears during use. In the illustrated preferred embodiment, the mask body 1 has a generally triangular front view shape, with the central interface 12 and the two headband connecting portions 15 respectively located near its three vertices. This facilitates stable wearing of the respiratory mask on the face by the patient and ensures good ventilation and sealing.
[0041] In the breathing mask provided by this utility model, the middle bone beam arm 2, the left bone beam arm 3, and the right bone beam arm 4 can be detachably connected to the mask body 1 in the same or different ways. This detachable connection can be achieved in various ways. For example, the middle bone beam arm 2, the left bone beam arm 3, and the right bone beam arm 4 can be provided with Velcro or magnetic elements for mutual adhesion to their corresponding middle interface 12, left interface 13, and right interface 14, so that their detachable connection can be achieved through adhesion or magnetic attraction. As an example, at least one of the middle interface 12, left interface 13, and right interface 14 is configured to be detachably connected to the corresponding middle bone beam arm 2, left bone beam arm 3, and right bone beam arm 4 by a snap fastener, pin, hinge, adhesion, or magnetic attraction. Several different connection methods are described below with reference to the illustrated preferred embodiments. It is understood that the connection method described in conjunction with one preferred embodiment can be used in other embodiments, and the connection method used for any one of the middle bone beam arm 2, left bone beam arm 3, and right bone beam arm 4 can also be applied to the connection of other bone beam arms.
[0042] like Figure 4As shown, the left interface 13 of the mask body 1 is configured with a snap-fit protrusion 13a and a snap-fit groove 13b. Correspondingly, the left bone beam arm 3 can have a mating groove and a mating protrusion that mate with the snap-fit protrusion 13a and the snap-fit groove 13b. Thus, from the illustrated perspective, the left bone beam arm 3 can be opened by being tilted upwards ( Figure 2 The face mask body 1 is joined in the direction shown in F1, such that its mating groove engages with the snap-fit protrusion 13a of the left interface 13, and the mating protrusion is embedded in the snap-fit groove 13b of the left interface 13. The right interface 14 of the face mask body 1 may have the same structure as the left interface 13. When it is necessary to remove the left bone beam arm 3 or the right bone beam arm 4 from the face mask body 1, it is done in the opposite direction ( Figure 2 The direction shown in F2 is pulled out. In the second usage state, with the left bony arm 3 and right bony arm 4 assembled, the force (main force) on the left bony arm 3 and right bony arm 4 is generally directed towards the human head, such as... Figure 2 The direction shown in F3 makes the angle between it and the direction of the force applied when removing the left and right bone beam arms 3 and 4 from the mask body 1 greater than 90°, thus preventing the left and right bone beam arms 3 and 4 from accidentally falling off during use.
[0043] Reference Figure 5 and Figure 6 In a preferred embodiment, the intermediate interface 12 of the mask body 1 is configured with a mounting slot 12c for inserting and connecting the intermediate bone beam arm 2, and the intermediate interface 12 has a limiting hole 12a for defining the intermediate bone beam arm 2 at the insertion position. The intermediate bone beam arm 2 has a limiting protrusion 21 for engaging with the limiting hole 12a. Thus, when it is necessary to connect the intermediate bone beam arm 2, the intermediate bone beam arm 2 can be inserted along... Figure 8 As shown in Figure F1, insert the device into the mounting slot 12c of the intermediate interface 12 until the limiting protrusion 21 is engaged in the limiting hole 12a. At this time, the force (main force) on the intermediate bone beam arm 2 is generally directed towards the human head. Figure 8 (as shown in F3), and removing the intermediate bone beam arm 2 from the mask body 1 requires applying an application at least away from the center of the mask body 1 (in the direction shown in F3). Figure 8 The pulling force (in the direction shown by F2) and the included angle between them are greater than 90°, thereby preventing the accidental detachment of the intermediate bone beam arm 2 in the first use state. In another embodiment, the positions of the limiting protrusion 21 and the limiting hole 12a can be interchanged, that is, the limiting protrusion 21 is set on the mask body 1, and the limiting hole 12a is set on the intermediate bone beam arm 2, which can also play the role of locking the insertion relationship between the two.
[0044] Figures 7 to 10The preferred embodiment shown provides another detachable connection method between the intermediate skeletal arm 2 and the mask body 1. Specifically, the breathing mask of this preferred embodiment has a positioning pin 51, and positioning holes 12b are formed at corresponding positions of the intermediate interface 12 of the mask body 1 and the intermediate skeletal arm 2, so that the positioning pin 51 can be inserted into the positioning hole 12b to be configured in a first use state with the intermediate skeletal arm 2 connected. For ease of connection, the intermediate skeletal arm 2 and the mask body 1 can also be inserted together, so that the positioning pin 51 is mainly used to lock the insertion position of the two.
[0045] like Figure 10 As shown, the preferred embodiment of the breathing mask includes a fastener 5, which has a locking structure 52 for engaging with the mask body 1. The locking structure 52 shown in the figure is configured as a locking protrusion that engages with the mask body 1. Correspondingly, locking grooves can be formed on both sides of the intermediate interface 12 of the mask body 1 so that the fastener 5 can be engaged and fixed to the mask body 1. A positioning pin 51 for locking the insertion position of the intermediate bone beam arm 2 and the mask body 1 is provided on the fastener 5. Thus, when the intermediate bone beam arm 2 is inserted into the intermediate interface 12 of the mask body 1, by engaging the fastener 5 with the mask body 1, the positioning pin 51 on it can pass through the positioning hole 12b of the intermediate bone beam arm 2 and the intermediate interface 12, thereby achieving a detachable connection of the intermediate bone beam arm 2. In this preferred embodiment, the angle between the direction of the force (main force) on the intermediate bone beam arm 2 when worn and the direction of the force applied when the intermediate bone beam arm 2 is removed from the mask body 1 is not less than 90°, thereby preventing the intermediate bone beam arm 2 from accidentally falling off in the first use state.
[0046] A second aspect of this invention also provides a ventilation therapy device including the above-described breathing mask.
[0047] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including combinations of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
