Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a headband component and a mask system. Background Art

[0002] In some scenarios, in order to treat respiratory diseases such as obstructive sleep apnea, respiratory insufficiency, chronic obstructive pulmonary disease and chest wall disease, the patient needs to wear a breathing mask to input the gas generated by the breathing device into the patient's respiratory tract.

[0003] In order to prevent the mask from being separated from the patient, a headband assembly is designed in the related art to fix the mask on the patient's head. Part of the mask is wrapped around the back of the head through the headband, so that the mask fits tightly on the patient's face.

[0004] However, since this type of headband only wraps the back of the head and the area enveloping the head is relatively small, the effect of this type of headband in fixing the mask is not ideal. The patient's unconscious activities often cause the headband to shift, resulting in a weakened mask wrapping, which in turn causes air leakage or noise, making the patient feel uncomfortable and even affecting the patient's treatment effect.

[0020] In one embodiment, the upper fixing component, the lower fixing component, the first fixing belt and the second fixing belt all have a belt width of 5-25 mm.

[0021] In one embodiment, the stiffness of the upper fixing assembly is less than or greater than the stiffness of the lower fixing assembly.

[0047] The utility model will be further described below in conjunction with the accompanying drawings.

[0048] like Figure 1 As shown, an embodiment of the present application provides a headband assembly, which includes: an upper fixing assembly 1 and a lower fixing assembly 2 connected to each other, wherein the upper fixing assembly 1 and the lower fixing assembly 2 are both closed structures. In addition, the upper fixing assembly 1 is also connected to a first fixing belt 3, and the lower fixing assembly 2 is also connected to a second fixing belt 4.

[0049] It should be noted that the closed structure can not only Figure 1 The ring structure shown in the figure can also adopt a multi-ring structure in which multiple rings are connected or intersected.

[0050] When in use, the first fixing belt 3 is connected to the breathing mask 9, and the second fixing belt 4 is connected to the breathing mask 9, so that the mask system is assembled. Then, the assembled mask system is worn on the patient's head so that the relevant gas is input into the patient's respiratory tract through the mask system.

[0051] like Figure 2 as well as Figure 3 As shown, when worn on the patient's head, the upper fixing component 1 partially fits the top area of ​​the patient's head, and the lower fixing component 2 fits the back area of ​​the patient's head. The headband component not only wraps the top and back of the head, but also allows the headband component to be more firmly worn on the patient's head, reducing the risk of misalignment of the headband component.

[0052] See also Figure 4 As shown, in some embodiments, only part of the upper fixing assembly 1 fits the top area of ​​the patient's head, while the other part fits the rear area of ​​the patient's head. In other embodiments, it can also be designed that the upper fixing assembly 1 fits the top area of ​​the patient's head.

[0053] In addition, since the upper fixing component 1 and the lower fixing component 2 of the headband assembly fit the patient's head, the closed structure has a larger contact area than when the strip-shaped belt body fits the patient's head, and is more convenient to wear, and the breathing mask 9 connected to the headband assembly can be more stably fitted to the patient's face.

[0054] Among them, since the upper fixing component 1 is connected to the lower fixing component 2, and the areas where the upper fixing component 1 and the lower fixing component 2 are attached to the patient's head are far apart, unconscious activities are generally difficult to cause the upper fixing component 1 and the lower fixing component 2 to shift at the same time.

[0055] When one annular belt is deflected due to the patient's unconscious movement, the breathing mask 9 will still be maintained at the original position under the constraint of the other annular belt. And after the patient stops the unconscious movement, the deflected annular belt will gradually move back to the initial position under the constraint of the other annular belt and the breathing mask 9 due to the disappearance of the external force.

[0056] The dimension of the upper fixing assembly 1 along the width direction is Figure 5 W1 in the figure, and the dimension of the lower fixing component 2 along the width direction is Figure 5 W2 in the figure, wherein W1>W2. When the headband assembly is worn on the patient's head, the upper fixing assembly 1 can cover a longer area in the width direction. This improves the wrapping of the top of the patient's head and prevents the lower fixing assembly 2 from being too long in the width direction and touching the patient's ear area, causing discomfort to the patient.

[0057] like Figure 5 As shown, in some embodiments, the dimension of the lower fixing component 2 along the width direction is equal to 1 / 2-2 / 3 of the dimension of the upper fixing component 1 along the width direction. Through the above design, it is more suitable for wearing on the human head.

[0058] In some embodiments, the dimension of the upper fixing component 1 along the width direction is 160-320 mm. The dimension here refers to the dimension of the outer contour in the width direction. The applicant has found that when the dimension of the upper fixing component 1 along the width direction is 160-320 mm, the fitting effect of the upper fixing component 1 in the top area of ​​the patient's head is relatively good.

[0059] That is to say, the use of the headband assembly provided in the present application can not only improve the firmness of the mask fitting the face, but also reduce the deviation of the breathing mask 9 caused by the patient's unconscious activities, thereby reducing the risk of air leakage in the breathing mask 9.

[0060] like Figure 1 as well as Figure 4 As shown, in one implementation, the upper fixing assembly 1 includes a top head strap 11 and a back head strap 12, which are connected end to end to form an annular structure, wherein the top head strap 11 is used to fit the top area of ​​the patient's head, and the back head strap 12 is used to fit the back area of ​​the patient's head.

[0061] That is to say, the upper fixing component 1 is simultaneously attached to the top area and the back area of ​​the patient's head, and the top band 11 attached to the top area and the back band 12 attached to the back area are connected to form an annular structure. When worn, the top band 11 and the back band 12 form an annular structure that is framed in the top back area of ​​the head. The upper fixing component 1 is smaller than the head circumference, and a portion of the junction between the top and the back of the head passes through the upper fixing component 1. In addition, the upper fixing component 1 is subjected to tension at three locations, so it can maintain good wrapping and contact with the head circumference. When the annular structure formed by the top band 11 and the back band 12 is sleeved in the transition area between the top and the back of the head, the inherent outer contour of the patient's head is used to reduce the risk of displacement of the upper fixing component 1, and to improve the closeness of the fit between the upper fixing component 1 and the patient's head, so that the headband assembly can more securely fix the breathing mask 9.

[0062] like Figure 1 , Figure 2 as well as Figure 3 As shown, in some implementations, the first fixing belt 3 is connected approximately at the intersection of the top head belt 11 and the back head belt 12 when worn.

[0063] When the headband assembly is worn, the first fixing strap 3 is in a tensioned state to make the breathing mask 9 fit closely to the patient's face, and the upper fixing assembly 1 fit closely to the patient's head. By connecting the first fixing strap 3 to the intersection of the top strap 11 and the back strap 12, after the first fixing strap 3 is tightened, the upper fixing assembly 1 fits closely to the intersection of the back of the head and the top of the head, and sufficient force is applied to the upper part of the mask.

[0064] In particular, the width of the first fixing belt 3 is increased at the connection point between the first fixing belt 3 and the upper fixing component 1 to increase the local strength of the first fixing belt 3 and avoid the first fixing belt 3 from breaking at the connection point between the first fixing belt 3 and the upper fixing component 1 .

[0065] like Figure 1 as well as Figure 4 As shown, in some implementations, the lower fixing component 2 is connected to the side of the back head strap 12 away from the top head strap 11. When the second fixing strap 4 tightens the lower fixing component 2, the back head strap 12 can be tightened downward by the lower fixing component 2, thereby achieving the effect of the back head strap 12 tightening the top head strap 11 downward, thereby improving the stability of the top head strap 11.

[0066] like Figure 2 As shown, the headband assembly is configured so that when worn on the patient's head, the first fixing belt 3 and the second fixing belt 4 are located on opposite sides of the patient's ears, and the headband and the mask of the present patent are well wrapped with the head in all directions, such as top, bottom, left, right, and right. Even if the patient has more intense unconscious activities, no matter which direction the force is applied, whether it is applied in the up, down, left, right, or left direction, or the force pulled by the pipe connected to the mask, the seal between the mask and the patient's face will not be damaged.

[0067] See also Figure 2 as well as Figure 3 As shown, in some implementations, the headband assembly is configured so that when worn on the patient's head, the first fixing strap 3 and the second fixing strap 4 are arranged at an angle.

[0068] The first fixing belt 3 and the second fixing belt 4 arranged at an angle can transmit tension forces in different directions, so that the upper fixing component 1 and the lower fixing component 2 are tightened with tension forces in different directions, thereby improving the reliability of the headband component.

[0069] Specifically, when the headband assembly is worn on the patient's head and the patient is in a forward-looking posture, the first fixing belt 3 moves away from the upper fixing assembly 1 in an oblique downward direction, and the second fixing belt 4 extends approximately in a horizontal direction.

[0070] See also Figure 2as well as Figure 3 As shown, the second fixing belt 4 is connected to a side of the lower fixing component 2 away from the upper fixing component 1 .

[0071] See also Figure 1 As shown, the first fixing belt 3 is spaced apart from the second fixing belt 4. The forces applied from the 4 points of the headband are applied to the mask, and these 4 points are relatively spaced apart and evenly distributed, which is conducive to the mask and the face fitting well in all directions.

[0072] like Figure 1 and Figure 6 As shown, in some implementations, two opposite ends of the upper fixing component 1 are each connected to a first fixing belt 3 , and / or two opposite ends of the lower fixing component 2 are each connected to a second fixing belt 4 .

[0073] By connecting a first fixing belt 3 to each of the two opposite ends of the upper fixing component 1 in the width direction, the upper fixing component 1 can be tightened in the width direction by the two first fixing belts 3. In addition, by connecting the first fixing belt 3 to the middle area of ​​the upper fixing component 1, it can be better ensured that the deformation length of each area of ​​the first fixing belt 3 is relatively uniform and maintains its annular shape, so as to avoid that some areas of the upper fixing component 1 are in a state of relaxation or too low tension, which makes it difficult to fit firmly on the patient's head.

[0074] See also Figure 1 , Figure 2 as well as Figure 5 As shown, the dimension of the upper fixing component 1 along the width direction is greater than the dimension of the lower fixing component 2 along the width direction, and the width direction refers to the extension direction of the first fixing belt 3 .

[0075] In some implementations, the upper fixing assembly 1 and the lower fixing assembly 2 are symmetrical along a first symmetry axis, and the extension direction of the first symmetry axis is perpendicular to the width direction. By setting a symmetrical structure, the aesthetics of the headband assembly can be improved, and when worn, the fitting area of ​​the headband assembly on the patient's head is relatively symmetrical, and the headband assemblies on both sides of the first symmetry axis have approximately equal tension.

[0076] Preferably, the size of the upper fixing component 1 along the width direction is 200-280 mm. The upper fixing component 1 within this width range not only has a better fitting effect, but also is more suitable for the patient's head contour.

[0077] See also Figures 7 to 14 As shown, the upper fixing component and / or the lower fixing component form a hollow structure, and the hollow structure is one of a circle, an ellipse, a racetrack, and a polygon. The specific shape of the hollow structure can be selected according to the modeling requirements.

[0078] If the upper fixing component 1 is formed with a hollow structure, the hollow structure formed by the upper fixing component 1 is Figures 7 to 14The first hollow area 13 marked in the middle, and the hollow structure formed by the lower fixing component 2 is Figures 7 to 14 The second hollow area 21 is marked in the middle. The upper fixing component 1 and the lower fixing component 2 can be formed with a hollow structure at the same time, or only one of them can be formed with a hollow structure.

[0079] When both the upper fixing component 1 and the lower fixing component 2 are formed with a hollow structure, the shapes of the first hollow area 13 and the second hollow area 21 may be the same or different.

[0080] The size of the hollow structure in the length direction is 40-200 mm, that is, the range of L1 and L2 in the figure is 40-200 mm. The applicant has found that the first hollow area 13 within this size range can better fit the upper fixing component 1 to the top rear area of ​​the head.

[0081] Furthermore, the length dimension of the hollow structure is 100-150 mm, that is, the range of L1 and L2 in the figure is 100-150 mm, and the hollow structure with the length dimension within this range is more in line with the contour of the human head.

[0082] In some embodiments, the bandwidth of the upper fixing component 1, the lower fixing component 2, the first fixing belt 3 and the second fixing belt 4 are all within a range of 5-25 mm. The bandwidth within this range can not only ensure the strength and elasticity of the belt body, but also provide a relatively comfortable wearing effect.

[0083] Among them, local widening can be done at the junction of the two belts, such as Figure 4 as well as Figure 5 As shown, the first fixing belt 3 is partially widened at the connection between the first fixing belt 3 and the upper fixing component 1, and the upper fixing component 1 is partially widened at the connection between the lower fixing component 2. This can reduce the risk of the first fixing belt 3 breaking at the connection with the upper fixing component 1, and extend the service life of the headband assembly.

[0084] In some implementations, the rigidity of the upper fixing component 1 is less than or greater than the rigidity of the lower fixing component 2. In other words, the upper fixing component 1 and the lower fixing component 2 have different elasticities and can have different deformation amounts under the same tensioning force, so that the headband component with a planar structure can form a curved surface structure after unfolding, so as to better fit the patient's head.

[0085] In other implementations, the stiffness of the upper fixing assembly 1 may also be set to be equal to the stiffness of the lower fixing assembly 2 .

[0086] In some implementations, the upper fixing component 1, the lower fixing component 2, the first fixing belt 3 and the second fixing belt 4 are cut and formed in one piece, molded in one piece, or spliced ​​in parts into a whole. The positioning accuracy of the integral molding is high, and the connection stress at the connection of each component is small. Alternatively, the utilization rate of the fabric can be improved by cutting and forming in parts and then splicing them together to reduce the cost.

[0087] like Figure 1 as well as Figure 2 As shown, the first fixing belt 3 and / or the second fixing belt 4 are connected with a connecting member 5, and the connecting member 5 is used to be detachably connected to the breathing mask 9. In the present application, both the first fixing belt 3 and the second fixing belt 4 are connected with the connecting member 5. In other embodiments, only one of the first fixing belt 3 or the second fixing belt 4 may be connected with the connecting member 5, and the other fixing belt may be designed to be directly connected to the breathing mask 9.

[0088] The first fixing belt 3 and the breathing mask 9 can be detachably connected by the connecting member 5, and the first fixing belt 3 and the breathing mask 9 can be connected or separated by adjusting the connecting member 5. In the present application, the connecting member 5 is a Velcro, and the tightness of the first fixing belt 3 can be adjusted by adjusting the fitting area of ​​the Velcro. In other embodiments, the connecting member 5 can also be other detachable structures, such as a clamping structure, a slot structure, or a plug-in structure.

[0089] In some embodiments, the upper fixing component 1, the lower fixing component 2, the first fixing belt 3 and the second fixing belt 4 are made of at least one of nylon, nylon, spandex, polyurethane, PP, TPE and TPU.

[0090] Specifically, it can be made of a single material, or it can be made of a single material as a skeleton and combined with other materials to weave.

[0091] In some embodiments, the connection method between the upper fixing component 1 and the lower fixing component 2, the connection method between the upper fixing component 1 and the first fixing belt 3, and the connection method between the lower fixing component 2 and the second fixing belt 4 include at least one of sewing, bonding, ultrasonic welding, high-frequency welding, and hinging.

[0092] The present application also provides a mask system, which includes a breathing mask 9 and the above-mentioned headband assembly, wherein the breathing mask 9 is connected to the headband assembly. Specifically, the breathing mask 9 is connected to the first fixing belt 3 and the second fixing belt 4.

[0093] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
