Description

Technical Field

[0001] This utility model relates to the field of ventilation therapy, and more specifically to a headband and a breathing mask including the headband. Background Technology

[0002] Respiratory disorders include obstructive sleep apnea (OSA), Cheyne-Stokes respiratory system (CSR), respiratory insufficiency, obesity-related hyperventilation syndrome (OHS), chronic obstructive pulmonary disease (COPD), neuromuscular diseases (NMD), and chest wall diseases.

[0003] Mechanical ventilation is an effective treatment for the aforementioned respiratory diseases. Mechanical ventilation is divided into two forms: invasive ventilation (using intubation) and non-invasive ventilation (using a face mask). A breathing mask is a patient interface in a non-invasive mechanical ventilation system. By wearing the mask, air from the breathing device is delivered into the patient's airway through the nose and / or mouth. After being worn, the mask forms a seal against the patient's face to facilitate treatment under appropriate positive pressure.

[0004] However, the breathing masks currently on the market have the following drawbacks: the main body of the breathing mask (including the frame, padding, and tube) is worn directly on the patient's head through a headband connected to the frame. When the patient needs to remove the breathing mask for a short time during treatment (such as going to the bathroom), the headband needs to be removed from the head and then put on again. When putting on the headband again, it needs to be readjusted to ensure a seal between the mask and the face, making the operation and adjustment very cumbersome. Utility Model Content

[0005] The purpose of this invention is to overcome the problem that existing breathing masks are very cumbersome to operate and adjust when worn repeatedly.

[0010] In some embodiments, the main strap is provided with at least one head circumference adjustment structure.

[0011] In some embodiments, the headband further includes a middle band with its two ends connected to opposite sides of the main band for resting against the back of the patient's head.

[0012] In some embodiments, the main belt is provided with a first head circumference adjustment structure, which is a retractable belt that is part of the loop of the main belt.

[0013] In some embodiments, the two ends of the intermediate band are rotatably connected to the main band, so that the intermediate band can rotate between a wearing position against the back of the patient's head and a storage position close to one side of the main band.

[0014] In some embodiments, the main strap is provided with a second head circumference adjustment structure. The main strap has two ends, which are respectively formed as a first connecting end and a second connecting end. The second head circumference adjustment structure includes a first connecting structure disposed on the first connecting end and a second connecting structure disposed on the second connecting end. The first connecting structure and the second connecting structure are configured to enable the first connecting end and the second connecting end to be connected with an adjustable overlap length.

[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, see [link]. Figures 1-4 The headband 10 is used to be worn on the patient's head. The headband 10 includes a main band 11 in the shape of a ring and a first connecting part 12 disposed on the main band 11. The main band 11 is used to be placed on the patient's head and pass behind the patient's ears and below the occipital bone. The first connecting part 12 is disposed close to the patient's ears. At least two first connecting parts 12 are disposed close to the patient's two ears respectively. The first connecting part 12 is configured to be detachably connected to the connecting strap 21 of the breathing mask 20.

[0042] In the above, the main strip 11 can be made of rigid material or non-woven semi-rigid material, such as silicone, TPE, TPU, or PP.

[0043] It should be noted that this utility model actually divides the traditional headband into two parts. One part (i.e., the headband provided by this utility model) is worn separately on the patient's head. When the patient removes the breathing mask, this part is not removed from the head. Since there is no need to remove the headband, the operation of putting on and taking off the headband and the adjustment of the position and tightness of the headband relative to the head are eliminated. The other part (i.e., the connecting strap 21) is connected to the breathing mask and is removed together with the breathing mask. The breathing mask can be put on and taken off by connecting and disconnecting the connecting strap 21 from the headband 10, which can greatly simplify the operation and improve the patient's user experience.

[0044] This invention provides a headband for wearing on a patient's head, as described above. When using a breathing mask, the mask can be connected to the headband 10 via a connecting strap 21. When the patient needs to temporarily remove the mask, the connecting strap 21 can be detached from the headband 10. Compared to existing technologies, this simplifies operation, eliminates the need for headband readjustment, and offers greater convenience, significantly improving the patient's user experience.

[0045] In this invention, the first connecting part 12 can also be configured to allow for detachable connection of the mask. For patients whose skin is prone to allergies from silicone contact, holes corresponding to the nose and / or mouth can be cut out in the middle of a disposable mask for breathing. This perforated disposable mask can then be connected to the first connecting part 12 and worn on the patient's face. The breathing mask can then be connected to the headband 10 via the connecting strap 21, thereby achieving the effect of isolating the silicone (i.e., the padding of the breathing mask) from the skin and reducing allergies.

[0046] In this utility model, in order to improve the firmness and reliability of the connection between the connecting strap 21 and the headband 10, such as... Figures 1-5 As shown, at least two first connecting parts 12 are respectively provided on the main strap 11 at positions corresponding to the patient's ears on both sides, spaced apart from each other.

[0047] The first connecting portion 12 can have any suitable structure. Specifically, according to one embodiment of the present invention, such as... Figures 1-4 As shown, the first connecting portion 12 extends vertically upward from the upper end face of the main strap 11 (the position when the headband is worn on the patient's head), and includes a columnar root 121 and a head 122 located at the top of the root 121. The outer diameter of the head 122 is larger than the outer diameter of the root 121. By adopting this structure, the larger outer diameter of the head 122 in the first connecting portion 12 can play a role in preventing slippage, preventing the connecting strap 21 from detaching from the headband 10 due to non-human causes.

[0048] The head 122 can be triangular, conical, hemispherical, etc. When the outer diameter of the head 122 is inconsistent, the outer diameter of the head 122 mentioned above refers to the largest outer diameter.

[0049] In this invention, to adapt the headband to different patient head circumferences, at least one head circumference adjustment structure can be provided on the main strap 11. The head circumference adjustment structure can take any appropriate form, and when the main strap 11 has multiple head circumference adjustment structures, the multiple head circumference adjustment structures can take the same form or take different forms.

[0050] In one implementation, such as Figures 1-4As shown, the main strap 11 is provided with a first head circumference adjustment structure 14, which is a retractable strap that is part of the loop of the main strap 11. For ease of adjustment, the first head circumference adjustment structure 14 is located at the rear of the main strap 11; that is, the position of the first head circumference adjustment structure 14 can be set such that when the main strap 11 is worn on the patient's head, the first head circumference adjustment structure 14 is located at the rear of the patient's head (see...). Figure 5 ).

[0051] In another embodiment, the main strap 11 is provided with a second head circumference adjustment structure 15. The main strap 11 has two ends, namely a first connecting end and a second connecting end. The second head circumference adjustment structure 15 includes a first connecting structure disposed on the first connecting end and a second connecting structure disposed on the second connecting end. The first connecting structure and the second connecting structure are configured to allow the first connecting end and the second connecting end to be connected with an adjustable overlap length. That is, in this embodiment, the main strap 11 forms a closed loop through the connection of the first connecting structure and the second connecting structure.

[0052] The first and second connection structures can have any suitable structure. Specifically, for example... Figure 4 As shown, the first connection structure includes a plurality of connection holes 151 spaced apart along the length direction of the first connection end, and the second connection structure includes a connection post 152, which is configured to be selectively inserted into one of the connection holes 151.

[0053] In other embodiments, the main strap 11 may simultaneously provide a first head circumference adjustment structure 14 and a second head circumference adjustment structure 15. For example... Figure 4 As shown, the first head circumference adjustment structure 14 and the second head circumference adjustment structure 15 can be located on the front and rear sides of the main belt 11, respectively.

[0054] In this utility model, such as Figure 2 As shown, the headband 10 may also include a middle band 13, with its two ends connected to opposite sides of the main band 11 to support the back of the patient's head. By providing the middle band 13, the stability of the headband when worn on the patient's head can be improved.

[0055] The intermediate belt 13 can be made of a softer material than the main belt 11, such as a flexible material like fabric.

[0056] Preferably, the two ends of the middle strap 13 are rotatably connected to the main strap 11, allowing the middle strap 13 to rotate between a wearing position against the back of the patient's head and a storage position close to one side of the main strap 11. The middle strap 13 can be rotated open during use to adjust to a comfortable angle against the back of the patient's head to increase the stability of the headband (see [link]). Figure 2The headband 10 can be rotated to fit together with the main strap 11 when it is removed from the head for easy storage (see...). Figure 3 ).

[0057] Specifically, such as Figure 2 As shown, the two ends of the intermediate belt 13 can be rotatably connected to the main belt 11 via pins 16.

[0058] A second aspect of this utility model provides a breathing mask, see [link to relevant documentation] Figures 5-9 The breathing mask 20 includes a connecting strap 21 and a headband 10. The connecting strap 21 is provided with a second connecting part 211, which is configured to be adapted to connect with the first connecting part 12 of the headband 10.

[0059] When the first connecting portion 12 includes a root portion 121 and a head portion 122, the second connecting portion 211 may be a connecting hole. The diameter of the connecting hole is greater than or equal to the outer diameter of the root portion 121 and less than the outer diameter of the head portion 122.

[0060] In this utility model, see Figures 6-7 The breathing mask 20 may also include a frame 22, with two connecting straps 21 on each side of the frame 22. Each connecting strap 21 has a plurality of second connecting portions 211 spaced apart along its length. It is understood that the number of connecting straps 21 is the same as the number of first connecting portions 12, and they are connected one-to-one.

[0061] In order to facilitate the adjustment of the length of the connecting strap 21, the end of the connecting strap 21 that is connected to the frame 22 can be made adjustable. For example, a Velcro strap can be provided on this end of the connecting strap 21, and the strap can be self-connected after passing through the corresponding connecting hole on the frame 22.

[0062] In other implementations, see Figures 8-9 The ends of the two connecting straps 21 located on the same side of the frame 22 can also be connected to each other to form a whole, in order to further adapt to the patient's operating habits.

[0063] In this utility model, such as Figure 7 or Figure 9 As shown, the breathing mask 20 also includes a pad 23 and a bend 24.

[0064] Breathing masks can be mouth-nose masks, nasal masks, nasal pillow masks, etc.

[0065] The third aspect of this utility model provides a ventilation therapy system, including a breathing mask 20.

[0066] The ventilation therapy system described above may also include a main unit (gas source) and a ventilation line. The ventilation line is used to connect the main unit and the breathing mask 20, and delivers the breathing gas generated by the main unit to the breathing mask 20 for the patient to inhale.

[0067] The host device can be a ventilator or an oxygen therapy device, etc.
