Headband assemblies are the major component for connecting the respiratory-mask system and the human head, and because the heads of individuals differ greatly, headband assemblies are required to have a good comfortableness, a good conformability and enough adaptability. Accordingly, it can be seen that a proper structure of the headband assembly can enable most of the patients that wear a respiratory mask to obtain a usage state with excellent comfortableness and leakproofness.
The headband assembly that is mostly extensively used currently is of the “four-point type”; i.e., it is connected to the respiratory-mask system via four points, thereby realizing the comfortableness of the wearing of the respiratory-mask system. The “four-point-type” headband assemblies are generally “I-shaped” or “crown-shaped”.

The present application provides a headband assembly. As shown in
In the headband assembly according to the present application, by providing the upper headband having the preset width and the arch structure, the headband assembly can enable the upper headband of the headband assembly to completely cling to the top of the head while having a planar structure in the spread and deployed state, and prevents the case in which a portion of the upper headband is excessively tightened to the top of the head and another portion of the upper headband is disengaged from the top of the head. As compared with the I-shaped headband in the prior art, the headband assembly according to the present application can take into account the fixing of the head-top part, to improve the firmness when it is worn by a patient. Moreover, as compared with the crown-shaped headband in the prior art, the headband assembly according to the present application can realize the complete clinging to the top of the head while having a planar structure in the spread state, and, for realizing the same technical effects, the headband assembly according to the present application has a simpler manufacturing process, and greatly reduces the production cost.
When the headband assembly is worn on the head, the upper headband 11 having the preset width has a plurality of micro-surfaces, and the centers of curvature of the plurality of micro-surfaces are in the same plane. The micro-surfaces used herein refer to that, when the headband assembly is worn on the head, when the headband assembly is exerted a certain force and the upper headband 11 clings to the top of the head, the surface of the upper headband 11 that clings to the top of the head is formed by a plurality of micro-surfaces.
The centers of curvature of the plurality of micro-surfaces are in the same plane, wherein the plane is a stable central plane that is formed after the headband assembly has been stably worn, and the stable central plane is a virtual plane. It can be understood that, because, in wearing, different persons have different comfortable wearing points, different persons have different stable central planes after they have worn the headband assembly, and the centers of curvature of the points of the upper headband 11 are located in the stable central plane (in other words, as stated above, the upper headband 11 has a plurality of micro-surfaces, and the centers of curvature of the plurality of micro-surfaces are in the same plane).
The preset width of the upper headband 11 may be obtained from the relation between, when the headband assembly is worn on the head, the curvature radiuses of the micro-surfaces of the upper headband 11 and the curvature radiuses of the top of the head. Particularly, the positions of the top of the head that cling to the upper headband 11 have first micro-surfaces, and the curvature radiuses of the first micro-surfaces are the first radiuses. The upper headband 11 has second micro-surfaces that correspond to the first micro-surfaces, and the curvature radiuses of the second micro-surfaces are the second radiuses. When the structures and the areas of the first micro-surfaces and the second micro-surfaces become increasingly consistent, the ideal values of the second radiuses can be obtained, whereby the upper headband 11 and the top of the head can cling to the maximum extent. In this case, the curvature radiuses of the first micro-surfaces and the second micro-surfaces are in the same plane (i.e., the stable central plane).
Particularly, as shown in
When the space structure of the planes ΔS′ and the space structure of the planes ΔS infinitely approaches being the same, the upper headband 11 that they form can fully cling to the top of the head in use. When the space structure of the ΔS′ infinitely approaches the space structure of the ΔS, it can be obtained that the relation between r and R is:
r=kR+m,
wherein k is a parameter that is related to the design structure, the positioning points and the material characteristics of the headband, and m is a compensation value.
Generally, the material of the headband assembly has a certain elasticity, which allows the space structure of the ΔS′ and the space structure of the ΔS to have a deviation within a predetermined range, to obtain the deviation range Δr of r. It is set that, in the spread and deployed state of the upper headband, the width at the point A′ is d, and it is obtained that:
d=k′Δr cos θ+m′,
wherein k′ is a correction parameter, θ is the angle between Δr and d, and m′ is a correction value.
From the above formulas, the maximum width value of the upper headband 11 can be obtained, which can ensure the complete clinging between the upper headband and the top of the head, and prevent the case in which a portion of the upper headband is excessively tightened to the top of the head and another portion of the upper headband is disengaged from the top of the head. Thereby obtaining a good firmness of the entire headband assembly.
Preferably, the preset width of the upper headband 11 is 16-36 mm. When the width value of the upper headband 11 is small, it has a good conformability with the top of the head, but the stability is poor and the headband easily gets loose. When the width value is large, it has a good stability, but the conformability is poor, which reduces the comfortableness of the wearer. According to the demands, the headband width of the upper headband 11 may be determined according to the obtained widths d of the multiple points. For example, the width of an upper headband having a constant width may be obtained from the obtained width average value, and an upper headband having variable curvatures may be designed according to the variation of the width. It can be understood that, in order to better realize the firm clinging between the upper headband and the top of the head of the wearer, more detailed calculus algorithms or other algorithms may be used to further accurately calculate to obtain the width of the upper headband.
The width value of the upper headband 11 may be determined particularly according to the properties of the different elastic materials for manufacturing the upper headband 11, thereby realizing multiple designs of planar or crown headbands. In addition, according to the properties of the materials and so on, the upper headband 11 may be designed to be a band-shaped body of a constant width (shown in
Preferably, the widths of the two ends of the upper headband 11 are greater than the width of the middle part of the upper headband 11. The width of the middle part is less, which can prevent the case in which, when the upper headband is bearing a force, a portion of the upper headband is excessively tightened and another portion is warped, thereby obtaining a higher integral conformability of the upper headband. Moreover, the widths of the two ends of the upper headband are greater, which can ensure a larger clinging area, to improve the stability of the headband assembly.
Preferably, the curvature radius of the arch structure of the upper headband 11 gradually increases in the extension directions from the two ends to the middle part. Accordingly, the upper headband 11 can further conform to the features of the head, to improve the conformability of the upper headband, thereby enhancing the stability of the headband assembly.
The characteristics such as the widths and the curvature radiuses of the positions of the upper headband 11 may be particularly set according to the material characteristics, the head features and so on, to enable it to better cling to the head.
It can also be understood that the upper headband 11 may be formed by the splicing, cutting or stamping of the same one elastic material, and the upper headband may be formed by the splicing of different elastic materials.
In the headband assembly, besides the clinging of the upper headband 11 to the top of the head, the rear headband 12 is required to cling to the rear side of the head, whereby, when the connecting parts pull the head-mounting part 1 forwardly, the headband assembly can be firmly worn. The rear headband 12 may have multiple structures and forms.
In some embodiments, as shown in
Particularly, as shown in
In some embodiments, the third band body 123 comprises a third bottom band 1231 that connects one end of the first band body 121 that is further away from the upper headband 11 and one end of the second band body 122 that is further away from the upper headband 11. Preferably, the third bottom band 1231 is of an arch structure that faces the upper headband 11, wherein the facing refers to that the side of the arch structure of the upper headband 11 that is inwardly concave and the side of the arch structure of the third bottom band 1231 that is inwardly concave face each other.
In another embodiment, as shown in
In the embodiments shown in
More preferably, the included angle between the first band body 121 and the second band body 122 is 20°-70°.
Certainly, the first band body 121 and the second band body 122 may have alternations according to the detailed designs. For example, in the embodiment shown in
In the headband assembly, each of the connecting parts 2 comprises a side headband 21 that is connected to one side of the upper headband 11 and a bottom headband 22 that is connected to one side of the rear headband 12.
The side headbands 21 on the two sides are individually connected to the connection points of the upper headband 11 and the rear headband 12; in other words, the three are connected together. The smooth connection of the upper headband 11, the side headbands 21 and the rear headband 12 forms the smooth contact interface between the headband and the head. Two positioning points on the two sides of the head are determined, and the positioning points facilitate to more firmly wear the respiratory-mask system.
In the technical solutions according to the present application, the side headbands 21 on the two sides of the upper headband 11 and the bottom headbands 22 on the two sides of the rear headband 12 may be individually provided with a connection structure for connecting the respiratory mask (not shown in the drawings), which is the “four-point-type” connection mode (connection with the respiratory mask via four connection points).
In the “four-point-type” connection mode, preferably, the side headbands 21 and the bottom headbands 22 are parallel to each other in the deployed state, as shown in
In addition, on each of the sides of the head-mounting part 1, the ends of the side headbands 21 and the bottom headbands 22 that are further away from the head-mounting part 1 may be connected to each other to form a connecting band, as shown in
It can also be seen from the structures shown in
Here, it should also be noted that a person skilled in the art can understand that the head-mounting part 1 of the headband assembly may also have other shapes according to the demands, to satisfy the various demands of consumers on the styles of the headband, which is not described in detail here.
In order to facilitate to manufacture the planar headband assembly, preferably, the upper headband 11, the rear headband 12, the side headbands 21 and the bottom headbands 22 may be connected together by splicing. In other words, the headband assembly will be cut into the component parts of the flat planes, which are then spliced (for example, spliced by stitching, welding, pressure welding and so on). That can save the material, and reduce the difficulty in the manufacturing.
Preferably, as shown in
Further, particularly, as shown in
Alternatively, as shown in
The splicing between the bottom headbands 22 and the rear headband 12 may be as shown in
Particularly, as shown in
Certainly, the bottom headbands 22 may also be configured as two parts, and the two parts are on the two sides of the rear headband 12 and connected with the lower ends of the bottom headbands 22 (as shown in
Certainly, the spliced structure is not limited to those stated above, and the spliced structures stated above are preferable embodiments that enable the headband assembly to cling to the head better.
It should also be understood that the headband assembly may be formed by splicing, but it may also be integrally formed, i.e., cut entirely from a planar material or integrally formed by another mode. However, the splicing mode, as compared with the integrally forming mode, saves the material, has a simpler manufacturing process, saves the cost and improves the production efficiency. In addition, the connection may also be via snap fitting by using clips (for example, as shown in
According to another aspect of the present application, there is further provided a respiratory-mask system, wherein the respiratory-mask system comprises a respiratory mask and the headband assembly stated above, and the respiratory mask is connected to the connecting parts 2 on the two sides of the headband assembly. The respiratory-mask system employs the headband assembly stated above, which can enable firm wearing, reduce the manufacturing cost and improve the manufacturing efficiency.
