Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation therapy, specifically to a headband assembly, a breathing mask including the headband assembly, and a ventilation therapy device including the breathing mask. Background Technology
[0002] Several methods are known for delivering pressurized gas to patients to aid their breathing. Continuous positive airway pressure (CPAP) involves delivering pressurized air to a patient, typically through a patient interface such as a mouth-nose mask, nasal mask, or nasal pillow mask. CPAP therapy is used to treat snoring and obstructive sleep apnea (OSA), a condition characterized by repeated collapse of the upper airway during inspiration. Positive pressure keeps the upper airway open, preventing collapse. CPAP treatment for OSA has generally proven effective and safe. CPAP is also commonly used for patients with various respiratory conditions, including COPD (chronic obstructive pulmonary disease).
[0003] Non-invasive ventilation therapy involves a patient interface located on the patient's face, typically a mouth-nose mask, nasal mask, or nasal pillow mask. During treatment, an external breathing device, such as a ventilator, is used. The patient interface connects the gas pressure provided by the ventilator to the patient's airway, delivering breathing air into the patient's airway.
[0004] Breathing masks typically consist of an oronasal mask, a nasal mask, a soft face contact portion (such as a pad), a rigid or semi-rigid frame, a curved tube, and a headband. In use, the breathing mask is secured to the patient's face via the headband to deliver gas to the patient's airway at positive pressure.
[0005] To ensure stable wearing of the breathing mask, a bony arm typically extends from the frame. To enhance support and improve sealing, this bony arm is usually a 3D shape conforming to the face. Because this bony arm is rigid or semi-rigid and has a largely fixed shape, it may cause discomfort or poor sealing for patients with different face shapes and body types. Furthermore, since the headband is generally flexible, it may not provide sufficient fixation and sealing for the breathing mask. Utility Model Content
[0006] The purpose of this invention is to solve at least one of the above-mentioned problems.
[0007] To achieve the above objectives, the first aspect of this utility model provides a headband assembly, including a flexible main band and a rigid or semi-rigid member, wherein the main band is configured to wrap around a patient's head, and the rigid or semi-rigid member is configured to be detachably connected to any position of the main band such that the corresponding position of the main band is recessed inward or outward.
[0008] In some embodiments, the rigid or semi-rigid component is a magnetic component, and the main belt is provided with metal wires or metal powder that can be attracted to the magnetic component. The magnetic component is used to attract a portion of the main belt so that the rigidity of that portion increases and it deforms along with the magnetic component.
[0009] In some embodiments, the main strap has two ends for connection to the frame of the breathing mask, and at least a portion of the main strap near the ends is configured to be rigid or semi-rigid and deformable to be able to be recessed inward and outward.
[0010] In some embodiments, the magnetic element is configured to be shape-variable.
[0011] In some embodiments, the magnetic element is an arc-shaped sheet.
[0012] In some embodiments, the magnetic component includes a body and a magnet disposed within the body, the body being made of a rigid or semi-rigid material.
[0013] In some embodiments, the headband assembly further includes a middle band with its two ends connected to opposite sides of the main band.
[0014] In some embodiments, the two ends of the main band are respectively configured as self-connecting ends.
[0015] In some embodiments, the intermediate belt is a flexible belt, and the rigid or semi-rigid member is configured to be detachably connected to any position of the intermediate belt.
[0016] The second aspect of this utility model provides a breathing mask, the breathing mask including a frame and the aforementioned headband assembly, wherein the two ends of the main strap are respectively connected to the two ends of the frame.
[0017] In some embodiments, the breathing mask further includes two buckles, each of which is rotatably connected between the frame and the main strap.
[0018] In some embodiments, the breathing mask further includes a pad and an inlet tube, the pad for sealing connection with the patient's mouth and / or nose, the pad including an internally defined gas chamber and an inlet communicating with the gas chamber, the pad being connected to the frame, and the inlet tube being connected to the frame and communicating with the inlet.
[0019] In some embodiments, the buckle has a hook at one end and a hole at the opposite end, with connecting holes at both ends of the frame, the hook being rotatably connected to the connecting hole, and the end of the main strap being connected to the hole.
[0020] The third aspect of this utility model provides a ventilation therapy device, including the above-mentioned breathing mask.
[0021] The headband assembly of this invention incorporates rigid or semi-rigid components, which are detachably connected to any position on the main strap, allowing the corresponding position on the main strap to be recessed inwards or outwards. This increases the strength of the main strap, enhancing the secure seal against the breathing mask. Furthermore, when the rigid or semi-rigid components are connected to the main strap at the corresponding position on the patient's cheek, the deformation of the main strap can accommodate patients with different face shapes, thus preventing facial discomfort or poor sealing. Additionally, it provides extra support and stability to the breathing mask.

[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0041] The first aspect of this utility model provides a headband assembly, see [link]. Figures 1-4 The headband assembly 10 includes a flexible main band 11 and a rigid or semi-rigid member. The main band 11 is configured to wrap around the patient's head, and the rigid or semi-rigid member is configured to be detachably connected to any position of the main band 11 such that the corresponding position of the main band 11 is recessed inward or outward.
[0042] The headband assembly of this invention incorporates rigid or semi-rigid components, which are detachably connected to any position on the main strap, allowing the corresponding position on the main strap to be recessed inwards or outwards. This increases the strength of the main strap, enhancing the secure seal against the breathing mask. Furthermore, when the rigid or semi-rigid components are connected to the main strap at the corresponding position on the patient's cheek, the deformation of the main strap can accommodate patients with different face shapes, thus preventing facial discomfort or poor sealing. Additionally, it provides extra support and stability to the breathing mask.
[0043] In the above, the rigid or semi-rigid component can be detachably connected to the main belt in any suitable manner. For example, it can be a rigid or semi-rigid component that can be glued to the surface of the main belt (e.g., an adhesive layer is provided on one side of the rigid sheet).
[0044] In some embodiments, the rigid or semi-rigid component is a magnetic component 12, and the main belt 11 is provided with metal wires or metal powder (e.g., iron powder) that can be attracted to the magnetic component 12. The magnetic component 12 is used to be attracted to a part of the main belt 11 so that the rigidity of that part increases and deforms with the magnetic component 12.
[0045] See Figure 1 The main strap 11 has two ends for connecting to the frame 21 of the breathing mask 20. At least the portion of the main strap 11 near these ends is rigid or semi-rigid and deformable, allowing it to concave inwards and outwards. By making the portion of the main strap 11 near its two ends rigid or semi-rigid and deformable, it can accommodate patients with different face shapes, thus avoiding facial discomfort or poor seal. Furthermore, it provides additional support and stability to the breathing mask.
[0046] Specifically, such as Figures 1-4 In the illustrated embodiment, the headband assembly 10 includes a magnetic element 12. Iron powder is disposed within at least a portion of the main strap 11 near the end. The magnetic element 12 is used to adhere to this portion of the main strap 11 near the end, thereby increasing the rigidity of this portion and allowing it to deform in accordance with the magnetic element 12. In other words, compared to the prior art, the material of the main strap 11 remains unchanged, still using a flexible material. The improvement lies in the placement of iron powder within at least a portion of the main strap 11 near the end, achieving deformation by adhering to a magnetic element 12 of a certain shape on this portion. Since the magnetic element 12 is typically rigid or semi-rigid, the rigidity of this portion of the main strap 11 can be increased, providing additional support and stability to the breathing mask while adapting to the patient's face shape.
[0047] As described above, it should be noted that after the headband assembly 10 is worn on the patient's head, the main strap 11 is positioned around the patient's head circumference. The headband assembly 10 includes at least two magnetic elements 12. Iron powder within the main strap 11 can be attracted to the magnetic elements 12 and change shape to conform to the shape of the magnetic elements 12. The main strap 11 can change its shape by engaging with magnetic elements 12 of different shapes.
[0048] In some implementations, the magnetic element 12 may be configured to be shape-variable, so as to adjust to the corresponding shape according to the face shape of different patients.
[0049] In some embodiments, the magnetic element 12 can be configured to have an immutable shape. In practical applications, various models of magnetic elements 12 can be prefabricated, and the appropriate model can be selected based on the facial shape of different patients. The magnetic element 12 can be configured to be concave (see [reference]). Figures 1-2 ) or concave type (see Figures 3-4The curved sheet can be set to different curvatures according to requirements.
[0050] Specifically, the magnetic component 12 may include a body and a magnet disposed within the body, and the body may be a rigid or semi-rigid plastic component.
[0051] In this utility model, such as Figures 1-4 As shown, the headband assembly 10 may further include a middle strap 13, with its two ends connected to opposite sides of the main strap 11. By providing the middle strap 13, the stability of the headband assembly when worn on the patient's head can be improved. The middle strap 13 can be a flexible strap, or a rigid or semi-rigid component can be detachably connected to any position on the middle strap 13 to change its local shape, making it fit the patient's head better and enhancing the sealing of the breathing mask.
[0052] In this utility model, see Figures 1-4 The two ends of the main strap 11 can each be configured as self-connecting ends 111. For example, Velcro can be provided on the ends of the main strap 11, and self-adhesive can be made after it connects to the frame 21 (e.g., after passing through the connecting hole 211 on the frame 21). Of course, other types of self-connecting structures can also be used for the self-connecting ends 111.
[0053] In other embodiments, the two ends of the main strap 11 may also be configured to be connected to the frame 21 via other types of connection structures, such as snap-fit structures.
[0054] A second aspect of this utility model provides a breathing mask, see [link to relevant documentation] Figure 5 and Figure 6 The breathing mask 20 includes a frame 21 and a headband assembly 10, with the two ends of the main strap 11 connected to the two ends of the frame 21 respectively.
[0055] Specifically, in some embodiments, the two ends of the main belt 11 are directly connected to the two ends of the frame 21.
[0056] In other implementations, such as Figure 5 and Figure 6 As shown, the breathing mask 20 may also include two buckles 22, which are rotatably connected between the frame 21 and the main strap 11. That is, the two ends of the main strap 11 are connected to the two ends of the frame 21 via the buckles 22. The buckles 22 can improve the flexibility of the connection between the main strap 11 and the frame 21, increase the adaptability of the main strap 11 to the patient's face, and better avoid patient facial discomfort or poor seal.
[0057] The clasp 22 can have any suitable structure. Specifically, such as... Figure 7 and Figure 8In the embodiment shown, the fastener 22 has a hook portion 221 at one end and a hole portion 222 at the opposite end. Figure 5 As shown, the frame 21 has connection holes 211 at both ends, the hook part 221 of the buckle 22 can be rotatably connected to the connection hole 211, and the end of the main strap 11 can be connected to the hole part 222 of the buckle 22.
[0058] In this utility model, such as Figure 5 and Figure 6 As shown, the breathing mask 20 may also include a pad 23 and an inlet tube 24. The pad 23 is used for a sealed connection with the patient's mouth and / or nose. The pad 23 includes a gas chamber defined inside and an inlet communicating with the gas chamber. The pad 23 is connected to the frame 21. The inlet tube 24 is connected to the frame 21 and communicates with the inlet for supplying breathing gas to the gas chamber.
[0059] The pad 23 can be made of a relatively soft, elastic material. In the case of a nasal mask, such as... Figure 5 As shown, one end of the pad 23 is designed to form a seal with the patient's nose.
[0060] For ease of cleaning and maintenance, the liner 23 can be detachably connected to the frame 21.
[0061] See Figure 5 When the breathing mask 20 is a nasal mask, when the magnetic element 12 is attached to the portion of the main strap 11 near the end, that portion of the main strap 11 will change to the shape of the magnetic element 12 and become semi-rigid or rigid, which can provide additional support and stability to the nasal mask.
[0062] The third aspect of this utility model provides a ventilation therapy device, including a breathing mask 20.
[0063] The aforementioned ventilation therapy device may also include a main unit and a ventilation tubing. The ventilation tubing may connect the main unit and the breathing mask 20 (specifically, it may be connected to the air inlet tube 24 of the breathing mask 20) to deliver the breathing gas generated by the main unit to the breathing mask 20 for the patient to inhale.
[0064] The ventilation therapy equipment may be a ventilator or an oxygen therapy device, etc.
[0065] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
