[0068] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0069] This application discloses a head measuring device for measuring the head, so that the user can obtain accurate wearing specifications and provide reference for wearing a ventilated face mask in the form of a ventilated headband.

[0070] Reference Figures 1 to 24 As shown, the head measuring device includes a main body 10 and a measuring part 20. The main body 10 is configured to contact the user's head. The measuring part 20 is connected to the main body 10 and is configured as an adjustable structure. The adjustable structure includes a first adjusting part 221 and a second adjusting part 223. Adjustment is achieved by adjusting the different positions of the first adjusting part 221 and the second adjusting part 223.

[0071] The head measuring device of this application embodiment includes only a main body 10 and a measuring part 20, which has the advantage of simple structure. In use, the head measuring device is adjusted by combining different positions of the first adjusting part 221 and the second adjusting part 223 to obtain the head circumference. This has the advantage of simple and convenient adjustment, avoiding deviation during measurement, thus ensuring accurate measurement data and enabling the selection of the correct ventilation headband to enhance treatment effectiveness.

[0072] In some embodiments, the main body 10 includes a first end 11 and a second end 12. The measuring part 20 is connected to the first end 11 and the second end 12 respectively. By adjusting the different positions of the first adjusting part 221 and the second adjusting part 223, the distance between the first end 11 and the second end 12 can be adjusted so that the main body 10 contacts the head 30, which can avoid deviation during measurement and thus make the measurement data accurate.

[0073] In some embodiments, the main body 10 is configured to wrap around the nose and face, with a first end 11 and a second end 12 extending to the top of the head, and the measuring part 20 located at the top of the head. In the above structure of the embodiments of this application, the measuring part 20 is located at the top of the head, which facilitates the measurement operation.

[0074] In some embodiments, the main body 10 includes a first sub-body 13 and a second sub-body 14, the first sub-body 13 and the second sub-body 14 being strip-shaped structures respectively, the first sub-body 13 being configured to wrap around the nose and face; one end of the second sub-body 14 is connected to the first sub-body 13 located on the left side of the face, the other end of the second sub-body 14 is connected to the first sub-body 13 located on the right side of the face, and the second sub-body 14 is configured to wrap around the back of the head.

[0075] In this embodiment, the first sub-body 13 is mainly used to measure the head 30 to obtain accurate wearing specifications. The second sub-body 14 is an auxiliary strap, which can further prevent the main body 10 from shifting during measurement, thereby making the measurement data accurate.

[0076] In some embodiments, to better fit the wearing method of a ventilation mask with a nasal tube, the first sub-body 13 has a fixing part 15. This fixing part 15 is a structural component with a certain degree of rigidity, so that it fits snugly under the nose and improves comfort. See also... Figure 5 As shown, the fixing part 15 is provided under the nose and extends to the left and right sides under the nose.

[0077] In some embodiments, the first sub-body 13 and the second sub-body 14 are preferably made of flexible materials, such as silicone, foam, gel, fabric, etc., and secondarily of relatively rigid materials such as PP (polypropylene) and PC (polycarbonate). Two or more materials can also be used in combination, such as the first sub-body 13 except for the part of the fixing part 15 and the second sub-body 14 which are made of flexible materials, while the other parts are made of rigid materials.

[0078] It is understood that the molding method of the main body 10 is not limited in the embodiments of this application. The molding method of the main body 10 includes, but is not limited to, injection molding, cutting or 3D printing. The connection between the components in the main body 10 can be achieved by integral molding or by mechanical mechanism (such as mortise and tenon structure or buckle).

[0079] In some embodiments, the first adjustment portion 221 includes a plurality of first fold portions 211, arranged sequentially from the end of the first adjustment portion 221 connected to the main body 10 to the end of the first adjustment portion 221 away from the main body 10, with a first crease 212 between adjacent first adjustment portions 221; the second adjustment portion 223 includes a plurality of second fold portions 214, arranged sequentially from the end of the second adjustment portion 223 connected to the main body 10 to the end of the second adjustment portion 223 away from the main body 10, with a second crease 215 between adjacent second adjustment portions 223; the end of the first fold portion 211 furthest from the main body 10 and the end of the second fold portion 214 furthest from the main body 10 can be folded and connected. In use, the above structure of this embodiment allows for adjustment by folding the first fold portion 211 and / or the second fold portion 214, reducing the distance between the first end 11 and the second end 12 to allow the main body 10 to contact the head 30, thereby obtaining the head circumference, which has the advantages of simple and convenient operation.

[0080] It is understandable that the number of the first folding part 211 and the second folding part 214 is set according to the usage requirements, as long as the usage requirements are met.

[0081] In some embodiments, each first fold 211 is provided with a first size mark 213, and the mark value of the first size mark 213 increases sequentially from the end of the first adjustment part 221 connected to the main body 10 to the end of the first adjustment part 221 away from the main body 10; each second fold 214 is provided with a second size mark, and the mark value of the second size mark increases sequentially from the end of the second adjustment part 223 connected to the main body 10 to the end of the second adjustment part 223 away from the main body 10; the first fold 211 and the second fold 214 with the same mark value are adapted to be combined to achieve adjustment.

[0082] The first dimension mark 213 and the second dimension mark can be specific numerical values, such as values ​​in millimeters or centimeters; or they can be numerical ranges, specifications, etc. (Refer to...) Figure 4 The first dimension mark 213 and the second dimension mark shown are specifications, where L, M, and S represent the large, medium, and small specifications corresponding to the ventilation head with tubing. At this time, the first fold 211 with the L in the first dimension mark 213 and the second fold 214 with the L in the second dimension mark 213 are connected and located in the middle of the measuring section 20; the first fold 211 with the S in the first dimension mark 213 and the second fold 214 with the S in the second dimension mark 213 are located at both ends of the measuring section 20; the first fold 211 with the M in the first dimension mark 213 is located in the middle of the first adjusting section 221; and the second fold 214 with the M in the second dimension mark 223 is located in the middle of the second adjusting section 223.

[0083] To illustrate further, please refer to... Figures 3 to 7 As shown, the first adjustment part 221 and the second adjustment part 223 each have three folds, with dimensions marked as L, M and S, and each fold has creases on both sides.

[0084] The first adjustment part 221 includes a first folding part 211a, a first folding part 211b, and a first folding part 211c. The second adjustment part 223 includes a second folding part 214a, a second folding part 214b, and a second folding part 214c. The first folding part 211a and the second folding part 214a have a specification S, the first folding part 211b and the second folding part 214b have a specification M, and the first folding part 211c and the second folding part 214c have a specification L. The first folding part 211a is connected to the main body 10. A first crease 212a is formed between the first folding part 211a and the main body 10. A first crease 212b is formed between the first folding part 211a and the first folding part 211b. A first crease 212c is formed between the first folding part 211b and the first folding part 211c. A first crease 212d is formed between the first folding part 211c and the second folding part 214c. A second crease 215c is present between the second fold 214c and the second fold 214b, a second crease 215b is present between the second fold 214b and the second fold 214a, and a second crease 215a is present between the second fold 214a and the main body 10.

[0085] Reference Figure 5 As shown, when a user uses the head measuring device, the fixing part 15 is first placed under the nose, the second sub-body 14 is placed on the back of the head, i.e. the back of the head, the part of the first sub-body 13 other than the fixing part 15 is attached to the user's face and extends upward, the first end 11 and the second end 12 extend to the top of the head, and the measuring part 20 is located at the top of the head.

[0086] like Figure 6 As shown, when the user pinches the measuring part 20 with their fingers, the second fold 214c and the second fold 214c are rotated around the first crease 212d to overlap, the first fold 211b and the second fold 214b overlap, until the next set of folds can no longer overlap. At this time, the main body 10 is close to the user's face, and the curve formed by the main body 10 and the first fold 211 and the second fold 214 that cannot overlap is approximately the shape corresponding to the user's head, and its length is approximately the circumference of the user's head.

[0087] When a user uses the head measuring device to measure their head size, if the second fold 214c and the second fold 214c cannot overlap, it indicates that the user is suitable for a large-sized ventilation headband tube 40. If the second fold 214c and the second fold 214c can overlap, but the two first folds 211b and the second fold 214b cannot overlap, it indicates that the user is suitable for a medium-sized ventilation headband tube 40. If the second fold 214c and the second fold 214c, as well as the second fold 214c and the second fold 214c, can overlap respectively, but the first folds 211a and the second fold 214a cannot overlap, it indicates that the user is suitable for a small-sized ventilation headband tube 40. It is understood that the above are only usage examples; according to usage requirements, corresponding folds such as XS and XL can also be set to increase the size selection of the ventilation headband tube 40.

[0088] In some embodiments, refer to Figures 8 to 12 As shown, one or more first connecting structures 222 are provided on the first adjusting part 221, from the end of the first adjusting part 221 connected to the main body 10 to the end of the first adjusting part 221 away from the main body 10, and multiple first connecting structures 222 are arranged sequentially; one or more second connecting structures 224 are provided on the second adjusting part 223, from the end of the second adjusting part 223 connected to the main body 10 to the end of the second adjusting part 223 away from the main body 10, and multiple second connecting structures 224 are arranged sequentially; each first connecting structure 222 is connected to any one of the second connecting structures 224.

[0089] When the head measuring device of this embodiment is used, the first connecting structure 222 and the second connecting structure 224 are selected and connected to achieve different positions of the first adjusting part 221 and the second adjusting part 223, thereby adjusting and obtaining the head circumference, which has the advantages of simple and convenient adjustment.

[0090] In some embodiments, the first connecting structure 222 includes a first bayonet 225, which is recessed into the first adjusting portion 221 from its side end; the second connecting structure 224 includes a second bayonet 226, which is recessed into the second adjusting portion 223 from its side end; the opening of the first bayonet 225 faces the opening of the second bayonet 226, and each first bayonet 225 is adapted to be inserted into any one of the second bayonet 226. In the above structures of this application embodiment, the connecting structure using the first bayonet 225 inserted into the second bayonet 226 has the advantages of simple and convenient connection.

[0091] Among them, reference Figure 10As shown, the side ends of the first adjusting part 221 refer to its upper and lower ends, and the first latch 225 is recessed into the first adjusting part 221 from one side end. The side ends of the second adjusting part 223 refer to its upper and lower ends, and the second latch 226 is recessed into the second adjusting part 223 from one side end. It is important to note that during the connection of the first adjusting part 221 and the second adjusting part 223, the opening of the first latch 225 should face the opening of the second latch 226 to facilitate the connection.

[0092] Reference Figures 8 to 12 As shown, in some embodiments, a plurality of first latches 225 are provided on the first adjustment portion 221, arranged sequentially from the end of the first adjustment portion 221 connected to the main body 10 to the end of the first adjustment portion 221 away from the main body 10. A plurality of second latches 226 are provided on the second adjustment portion 223, arranged sequentially from the end of the second adjustment portion 223 connected to the main body 10 to the end of the second adjustment portion 223 away from the main body 10. In order to achieve effective fastening connection when the first latches 225 are inserted into the second latches 226, the length of the first latches 225 is more than half the width of the first adjustment portion 221 in the opening direction of the first latches 225; and the length of the second latches 226 is more than half the width of the second adjustment portion 223 in the opening direction of the second latches 226. Alternatively, in the opening direction of the first latches 225, the sum of the lengths of the first latches 225 and the second latches 226 is greater than or equal to the width of the first adjustment portion 221 and greater than the width of the second adjustment portion 223. Among them, reference Figure 10 As shown, the width of the first adjustment part 221 is between the upper and lower ends of the first adjustment part 221, and the width of the second adjustment part 223 is between the upper and lower ends of the second adjustment part 223.

[0093] Reference Figure 11 As shown, when a user uses this head card, they first wear the main body 10. The wearing method of the main body 10 can be referred to... Figure 5 The wearing method is shown.

[0094] Reference Figure 12 As shown, the user holds the distal ends of the first adjustment part 221 and the second adjustment part 223 with both hands and pulls them until they can no longer be stretched. At this point, the main body 10 comes into contact with the head 30, and then the first latch 225 and the second latch 226 are fastened together. The area between the main body 10 and the first adjustment part 221 at the fastening point, the area between the main body 10 and the second adjustment part 223 at the fastening point, and the curve formed by the main body 10 approximate the shape corresponding to the user's head, and its length is approximately the circumference of the user's head.

[0095] When a user uses the head measuring device to measure their head size, if the first latch 225 and the second latch 226 are engaged near the main body 10, it indicates that the user is suitable for wearing a small-sized ventilation headband tube 40; if the first latch 225 and the second latch 226 are engaged away from the main body 10, it indicates that the user is suitable for wearing a large-sized ventilation headband tube 40; if the first latch 225 and the second latch 226 are engaged in the middle position, it indicates that the user is suitable for wearing a medium-large-sized ventilation headband tube 40.

[0096] It is understandable that when the user fastens the first latch 225 and the second latch 226, there are multiple fastening methods. For example, the fastening points of the first latch 225 and the second latch 226 may be close to the first end 11 of the main body 10, but far away from the second end 12 of the main body 10. In this case, the appropriate model can be selected according to the preset selection rules.

[0097] Understandably, there are multiple preset selection rules. For example, one could calculate the first value of the first latch 225 within the range from the engagement point of the first latch 225 and the second latch 226 to the first end 11, and the other could calculate the second value of the second latch 226 within the range from the engagement point of the first latch 225 and the second latch 226 to the second end 12. When the sum of the first and second values ​​is low, it indicates that the user is suitable for wearing a small-sized ventilation headband tube 40; when the sum is high, it indicates that the user is suitable for wearing a large-sized ventilation headband tube 40; and when the sum is moderate, it indicates that the user is suitable for wearing a medium-sized ventilation headband tube 40.

[0098] In some embodiments, refer to Figure 13 As shown, the first connecting structure 222 further includes a third bayonet 227, which is recessed into the first adjusting portion 221 from the side end opposite to the first bayonet 225; the second connecting structure 224 further includes a fourth bayonet 228, which is recessed into the second adjusting portion 223 from the side end opposite to the second bayonet 226; the opening of the third bayonet 227 faces the opening of the fourth bayonet 228, and each third bayonet 227 is adapted to be inserted into any one of the fourth bayonet 228. The above-described structure of this application embodiment can achieve connection by inserting the first bayonet 225 into the second bayonet 226, or by inserting the third bayonet 227 into the fourth bayonet 228, which has the advantages of simple and convenient connection, and allows selection of suitable bayonet according to usage requirements, increasing the convenience of using the head measuring device.

[0099] In some embodiments, the arrangement of the first bayonet 225 and the third bayonet 227 can be as follows: Figure 13The staggered arrangement shown can be modified, although the first checkpoint 225 and the third checkpoint 227 can be arranged symmetrically. The second checkpoint 226 and the fourth checkpoint 228 can also be arranged in a different manner. Figure 13 The staggered arrangement shown can be modified to allow for a symmetrical arrangement of the second bayonet 226 and the fourth bayonet 228.

[0100] In some embodiments, refer to Figures 14 to 18 As shown, the first adjusting part 221 and the second adjusting part 223 are both strip structures. The first connecting structure 222 is disposed on the surface of the first adjusting part 221, and the second connecting structure 224 is disposed on the surface of the second adjusting part 223. The first connecting structure 222 and the second connecting structure 224 are either a snap fastener or an adhesive structure. The above-described structure of this application embodiment has the advantages of simple and convenient connection, with the first connecting structure 222 and the second connecting structure 224 being particularly advantageous.

[0101] The adhesive structure can be, for example, a hook and loop fastener, as long as it allows for adhesion.

[0102] Reference Figure 17 As shown, when a user uses this head measurement device, they first wear the main body 10. The wearing method of the main body 10 can be referred to... Figure 5 The wearing method is shown.

[0103] Reference Figure 18 As shown, the user holds the distal ends of the first adjustment part 221 and the second adjustment part 223 with both hands and pulls them until they can no longer be stretched. At this point, the main body 10 comes into contact with the head 30, and then the first connecting structure 222 and the second connecting structure 224 are connected. The area between the main body 10 and the first adjustment part 221 at the connection point, the area between the main body 10 and the second adjustment part 223 at the connection point, and the curve enclosed by the main body 10 approximates the shape corresponding to the user's head, and its length is approximately the circumference of the user's head.

[0104] When a user uses the head measuring device to measure their head size, if the connection point of the first connecting structure 222 and the second connecting structure 224 is close to the first end 11 and the second end 12 of the main body 10, it indicates that the user is suitable to wear a small-sized ventilation headband tube 40; if the connection point of the first connecting structure 222 and the second connecting structure 224 is far away from the first end 11 and the second end 12 of the main body 10, it indicates that the user is suitable to wear a large-sized ventilation headband tube 40; if the connection point of the first connecting structure 222 and the second connecting structure 224 is in the middle position, it indicates that the user is suitable to wear a medium-sized ventilation headband tube 40.

[0105] Reference Figures 19 to 23As shown, in some embodiments, the measuring unit 20 further includes a connector 231, which has a first through hole 234 and a second through hole 235; one end of the first adjusting part 221 is connected to the main body 10, and the distal end of the first adjusting part 221 passes through the first through hole 234 and connects to the first adjusting part 221 near the main body 10; one end of the second adjusting part 223 is connected to the main body 10, and the distal end of the second adjusting part 223 passes through the second through hole 235 and connects to the second adjusting part 223 near the second end 12. The above structure of the embodiments of this application also has the advantage of simple and convenient connection. Wherein, the distal end of the first adjusting part 221 refers to the end of the first adjusting part 221 away from the first end 11, and the distal end of the second adjusting part 223 refers to the end of the second adjusting part 223 away from the second end 12.

[0106] Furthermore, in order to ensure that the connection position between the distal end of the first adjustment part 221 and the first adjustment part 221 near the first end 11 does not change when the head measuring device is removed, and the connection position between the distal end of the second adjustment part 223 and the second adjustment part 223 near the second end 12 does not change, the above connections can be made using either a snap fastener or an adhesive structure, so as to ensure that the measurement results do not shift when the user removes the head measuring device.

[0107] In some embodiments, the connector 231 can be a D-ring buckle, which has the advantages of simple and convenient structure.

[0108] like Figure 22 As shown, when a user uses this head measurement device, they first wear the main body 10. The wearing method of the main body 10 can be referred to... Figure 5 The wearing method is shown.

[0109] like Figure 22 As shown, the user pinches the distal end of the first adjustment part 221 and pulls it until it can no longer be stretched. At this point, the main body 10 comes into contact with the head 30. Then, the distal end of the first adjustment part 221 is connected to the first adjustment part 221 near the first end 11. The curve formed by the first adjustment part 221, the second adjustment part 223, and the part of the main body 10 that is in close contact with the user's head is approximately the shape corresponding to the user's head, and its length is approximately the circumference of the user's head.

[0110] When a user uses the head measuring device to measure head size, if the length of the first adjustment part 221 passing through the first through hole 234 is too long, it indicates that the user is suitable to wear a small-sized ventilation headband tube 40; if it is too short, it indicates that the user is suitable to wear a large-sized ventilation headband tube 40; if the length is moderate, it indicates that the user is suitable to wear a medium-sized ventilation headband tube 40.

[0111] Further reference Figure 22 As shown, in the head measuring device described above, the first adjusting part 221 is movably connected to the connecting member 231, and the second adjusting part 223 is fixedly connected to the connecting member 231. Therefore, operation can be achieved by adjusting only the distal end of the first adjusting part 221.

[0112] In some embodiments, the first adjusting part 221 and the connector 231, as well as the second adjusting part 223 and the connector 231, are movably connected. During operation, the first adjusting part 221 can be fixed first, and then the second adjusting part 223 can be fixed. Alternatively, it can be operated with both hands, by pinching the distal ends of the first adjusting part 221 and the distal ends of the second adjusting part 223 with both hands and pulling them to both sides until they can no longer be stretched.

[0113] When a user uses the head measuring device to measure their head size, if the sum of the length of the portion of the first adjustment part 221 passing through the first through hole 234 and the portion of the second adjustment part 223 passing through the second through hole 235 is too long, it indicates that the user is suitable to wear a small-sized ventilation headband tube 40; if it is too short, it indicates that the user is suitable to wear a large-sized ventilation headband tube 40; if the length is moderate, it indicates that the user is suitable to wear a medium-sized ventilation headband tube 40.

[0114] The head measurement device of this application embodiment is adjusted by combining different positions of the first adjustment part 221 and the second adjustment part 223 to obtain the head circumference. It has the advantages of simple and convenient adjustment, which can avoid deviation during measurement, thereby making the measurement data accurate and enabling the selection of the correct size of the ventilation headband tube to increase the treatment effect.
