CONNECTING ELEMENT FOR A PATIENT INTERFACE

Description

[0001] Patient interfaces or breathing masks are used for ventilation, respiratory support, or as protective masks against aerosols consisting of solid or liquid particles. Breathing masks for ventilation or respiratory support form the interface between a user or patient and a ventilator and must be secured to the user's head with a connecting element. Both the breathing masks and the connecting elements must meet high standards of stability and safety while simultaneously providing sufficient comfort and ease of use for the user. A distinction must be made between breathing masks with forehead supports and breathing masks without forehead supports.

[0002] Forehead support-free breathing masks typically have stiffening devices in the connecting elements to ensure sufficient stability and a good fit of the breathing mask. The stiffened area is usually padded towards the user's face to increase comfort. The connecting elements are typically complex and sometimes difficult to use. Such connecting elements are shown, for example, in documents WO 2017 / 017573 A1, WO 2017 / 150990 A1, US 2020 / 269001 A1, WO 2011 / 060479 A1, and WO 2013 / 027174 A1. US 2017 / 0049984 discloses a connecting element for a patient interface according to the preamble of claim 1.

[0037] The following exemplary embodiments show a connecting element 10. Further features and advantages of the present invention will become clear in the following descriptions of exemplary embodiments with reference to the figures. The invention is not limited to the illustrated exemplary embodiments.

[0038] The connecting element 10 is suitable, for example, for use in a system 100 for ventilation and / or respiratory support. The system 100 comprises a patient interface 90 and a ventilator 70, which are connected to each other via a gas line 80. The patient interface 90 is connected to the head 95 of a patient via the connecting element 10.

[0039] The connecting element 10 is in an application state when the connecting element 10 is at least partially applied to the head 95 of a patient and / or user.

[0040] Fig. 1 shows an example overview of the system 100 with an embodiment of the connecting element 10, which is connected to a patient interface 90. The patient interface 90 can be connected to a ventilator 70 via a line 80. In Fig. 1 Patient interface 90, line 80, and ventilator 70 are shown not connected. A gas-conducting connection can be established by connecting line 80, for example, via connecting pieces at one end to patient interface 90 and at another end to ventilator 70 (not shown).

[0041] A patient interface 90 is any peripheral device designed to interact with a living being. In particular, the patient interface 90 is designed for therapeutic and / or diagnostic purposes in conjunction with the ventilator 70. The patient interface 90 can be designed as a breathing mask. Patient interface 90 and breathing mask are used synonymously herein.

[0042] The patient interface 90 can be designed as a nasal mask and completely or partially enclose the nose. The patient interface 90 can also be designed as a nasal cushion mask or nasal pillow mask. Nasal pillow masks are used, for example, in CPAP or bilevel therapy. The patient interface 90 can also be designed as nasal cannulas or oxygen cannulas. Nasal cannulas are used, for example, in high-flow therapy. Nasal cannulas can have nasal prongs 92 that can be at least partially inserted into the nostrils. The patient interface 90 can also be designed as a full-face mask or total-face mask, i.e., enclose the nose and mouth. Tracheal tubes or cannulas can also be used as the patient interface 90. The connecting element 10 is particularly suitable for nasal pillow masks and / or high-flow interfaces.

[0043] The patient interface 90 can be applied or attached to the head 95 of a user or patient via a connecting element 10. User and patient are used interchangeably herein. When the term "user" or "patient" is used, it refers to any individual who uses a breathing mask 90 with connecting element 10.

[0044] A ventilator 70 refers to any device that supports a user or patient in natural breathing and / or provides ventilation to a user or patient and / or provides respiratory therapy and / or otherwise influences the breathing of a user or patient. This includes, but is not limited to, respiratory therapy devices, CPAP, APAP, and bi-level devices, high-flow therapy devices, anesthesia or anesthesia devices, clinical, home, or emergency ventilators, oxygen O2-delivering devices, diagnostic systems, and coughing machines.

[0045] Patient interface 90 and ventilator 70 are preferably connected to each other via at least one line 80. Line 80 is designed as a gas line that connects the individual components of system 100 to each other in a gas-conducting manner. Line 80 is preferably designed to be flexible and / or rotatable. Line 80 can be designed, for example, as an elastic tube and / or hose and / or hose system.

[0046] Fig. 2 shows a perspective top view of a partial area of the connecting element 10. The connecting element 10 and sections of the connecting element 20, 40, 60 have a width B, a thickness D and a length L. The width B is usually greater than the thickness D. The length L is usually greater than the width B. In a state of use, i.e. when the connecting element 10 at least partially rests against the head 95 of the user (not shown here), the connecting element 10 faces the head 95 of the user at least in part on one side along the width B and along the length L.

[0047] Fig. 3 shows a schematic side view of an embodiment of the connecting element 10 in a state of use on the head 95 of a user. This embodiment is not in accordance with the invention and is for illustrative purposes only. The connecting element 10 comprises at least one bracket 20 and at least one behind-the-ear element 40. In addition, the connecting element can comprise at least one headband 60.

[0048] Out of Fig. 3 It can be seen that, in a state of use, the connecting element 10 is arranged on the head 95 of a patient such that the bracket 20 is arranged at least partially between the nose and the ear. In this case, the bracket 20 is located at least partially in a cheekbone region J.

[0049] The connecting element 10 can basically be mirror-symmetrical. The connecting element 10 can therefore have an imaginary plane of symmetry S (see Fig. 6A , 9) which is parallel to the plane spanned by the x- and y-axes (see for example Fig. 3 ). Basically mirror-symmetrical means that there is usually no perfect symmetry and the mirror images can differ in one or more details. The connecting element 10 can also have one or more additional elements that can be arranged on one side of the connecting element 10, regardless of the basic symmetry. An example here is a hose holder 93, which can only be arranged on one of the two brackets 20 (see, for example, Fig. 17 ). In the following, only one of the mirror-symmetrical halves of the connecting element 10 is generally described.

[0050] The connecting element 10 comprises at least one bracket 20. Typically, the connecting element 10 comprises two brackets 20. In one application state, the brackets 20 are located over parts of the left half of the face and over parts of the right half of the face (not shown). The connecting element 10 can also comprise more than two brackets 20.

[0051] The bracket 20 comprises a coupling system 22. The connecting element 10 can be coupled to the patient interface 90 via the coupling system 22. The coupling can be reversible or irreversible. The coupling system 22 can include a mechanism for length adjustment. The length L of the connecting element 10 can thus be adjusted via the coupling system 22. The coupling can be movable or immovable.

[0052] The patient interface 90 can be designed as a nasal pillow mask. Nasal pillow masks can be used, for example, for CPAP or bilevel therapies. For this purpose, the nasal pillow masks cover the nostrils and / or the area surrounding them in a gas-tight manner with a nasal pillow 91. The nasal pillow 91 can be inserted at least partially into the nostrils.

[0053] Fig. 4 und Fig. 5 show a side view of the bracket 20. The bracket 20 comprises a beginning 30 and an end 38. The beginning 30 and end 38 are located along the length L of the bracket 20 at opposite ends of the bracket 20. The bracket 20 terminates on one side at the beginning 30 and on the other side at the end 38. In a use state, the beginning 30 can be arranged adjacent to the patient interface 90 and the end 38 on the opposite side. The end 38 can be arranged on and / or behind the ear in a use state (see Fig. 3 ).

[0054] The bracket 20 extends along the length L from the beginning 30 to the end 38. The length L of the bracket 20 is substantially greater than the width B of the bracket 20. The ratio of the length L to the width B of the bracket 20 can be in a range from 10:1 to 40:1. For example, the ratio of the length L to the width B of the bracket 20 is at least 10:1. In some embodiments, the ratio of the length L to the width B of the bracket 20 is at least 20:1. In a preferred embodiment, the ratio of the length L to the width B of the bracket 20 is, for example, 25:1 or more. The bracket 20 has a particularly elongated, narrow shape.

[0055] The width B of the bracket 20 can be constant or variable. In an exemplary embodiment, the width B of the bracket 20 can be substantially constant and can increase or decrease in width B toward the beginning 30 and / or the end 38.

[0056] In a preferred embodiment, the width B increases towards the end 38 (see, for example, Fig. 10B , Fig. 16 ). The width B can increase or decrease towards the beginning 30. In a preferred embodiment, the width B increases towards the beginning 30 ( Fig. 4 ).

[0057] The width B of the bracket 20 can range between 1 and 20 mm. Preferably, the width B of the bracket 20 is between 3 and 10 mm. In a specific embodiment, the width B of the bracket 20 is essentially 7 mm.

[0058] The length L of the bracket 20 can range between 50 and 250 mm. Preferably, the length L of the bracket 20 is between 150 and 220 mm. In a specific embodiment, the length L of the bracket 20 is 200 mm, for example.

[0059] Out of Fig. 4 It can be seen that the bracket 20 can be formed straight and / or curved at least in sections. Fig. 4 and Fig. 5 show that the bracket 20 comprises several sections 31, 33, 35, 37, which can be differently shaped. The bracket 20 comprises several turning points 30, 32, 34, 36, 38, between which sections 31, 33, 35, 37 are arranged.

[0060] The beginning 30 of the bracket 20 can lie at the intersection point of the x- and y-axes. The beginning 30 defines a first outer end of the bracket 20, namely the end that is adjacent to the patient interface 90 and the coupling system 22 in a use state. The end 38 of the bracket 20 defines a second outer end of the bracket 20, namely the end that is arranged on and / or behind the ear in a use state. The bracket 20 can extend straight and / or bent or curved between the beginning 30 and the end 38 in the x / y coordinate system. The bracket 20 preferably extends in the x / y coordinate system such that the end 38 lies above the beginning 30 in the y-direction.

[0061] Between the beginning of 30 and the end of 38 there are at least three turning points 32, 34, 36. In the Fig. 4 / 5 In the specific embodiment shown, for example, there are three turning points 32, 34, 36 between the beginning 30 and the end 38. In alternative embodiments, fewer than three or more than three turning points can be formed.

[0062] Between the beginning 30 and the turning points 32, 34, 36 and the end 38 there are at least four sections 31, 33, 35, 37. In the Fig. 4 / 5 In the specific embodiment shown, for example, four sections 31, 33, 35, 37 lie between the beginning 30 and the end 38. In alternative embodiments, fewer than four or more than four sections may be formed. The sections 31, 33, 35, 37 may be straight and / or bent or curved.

[0063] A section 31 of the bracket 20 can be arranged between the beginning 30 and the turning point 32. Section 31 refers to the bracket section that lies between the beginning 30 and the turning point 32. The section 31 can be straight, bent, or curved. In the specific embodiment according to Fig. 4 Section 31 is essentially straight in the direction of the x-axis. The coupling system 22 can be arranged in section 31. A mechanism for length adjustment can be arranged in section 31.

[0064] A further section 33 of the bracket 20 can be arranged between the turning point 32 and the turning point 34. Section 33 refers to the bracket section that lies between the turning point 32 and the turning point 34. The section 33 can be straight, bent, or curved. In the specific embodiment according to Fig. 4 / 5Section 31 is curved in the x / y coordinate system. The inflection point 34 lies above the inflection point 32 in the y direction.

[0065] A further section 35 of the bracket 20 can be arranged between the turning point 34 and the turning point 36. Section 35 refers to the bracket section that lies between the turning point 34 and the turning point 36. The section 35 can be straight, bent, or curved. In the specific embodiment according to Fig. 4 / 5 Section 35 is curved in the x / y coordinate system. The inflection point 36 lies above the inflection point 34 in the y direction.

[0066] Fig. 5 illustrates the bending of sections 33 and 35 of the concrete embodiment according to Fig. 4 Section 33 is curved between turning points 32 and 34. The bend corresponds to an arc of an imaginary circle or oval with a radius R1. The radius R1 can, for example, be in a range between 60 mm and 75 mm. If turning points 32 and 34 are connected to a center point M1 of the circle or oval, a circular section with a central angle α1 is obtained. The central angle α1 can be in a range between 30° and 80°. For example, the central angle α1 is in a range between 60° and 70°.

[0067] Section 35 is curved between inflection points 34 and 36. The bend corresponds to the arc of an imaginary circle or oval with a radius R2. For example, the radius R2 can be in a range between 10 mm and 20 mm. Connecting inflection points 34 and 36 with a center point M2 of the circle or oval produces a circular segment with a central angle α2. The central angle α2 can be in a range between 30° and 80°. For example, the central angle α2 is in a range between 60° and 75°.

[0068] The central angles α1 and α2 can be equal or differ in size.

[0069] The bend or curvature of section 35 can, for example, be formed opposite to the bend or curvature of section 33. For example, a convexly curved bracket section 35 can adjoin a concavely curved bracket section 33 and vice versa.

[0070] The bracket 20 can be used in alternative embodiments instead of the Fig. 4 / 5 The arcuate curves shown can also be formed from straight sections 31, 33, 35, 37 which are bent relative to one another in such a way that the end 38 lies above the beginning 30 in the y-direction (not shown).

[0071] An end section 37 of the bracket 20 is arranged between the turning point 36 and the end 38. End section 37 can refer to the bracket section located between the turning point 36 and the end 38. The end section 37 is adjacent to the end 38 and refers to the last section of the bracket 20.

[0072] The end section 37 can be straight and / or bent or curved. In the specific embodiment according to Fig. 4 the end section 37 is essentially straight in the direction of the x-axis.

[0073] In some embodiments, the end portion 37 may be substantially longer than in Fig. 4 / 5 shown. The length L of the end section 37 can amount to up to 80% of the total length L of the bracket 20. Preferably, the length L of the end section 37 amounts to less than 50% of the total length L of the bracket 20. In a specific exemplary embodiment, the length L of the end section 37 amounts to 20% to 25% of the total length L of the bracket 20. A short end section 37 has a positive effect on wearing comfort for the user, for example when the user rests their head while lying down, for example when sleeping.

[0074] In some embodiments, it is conceivable that an elongated end portion 37 can be straight and curved or bent. For example, it is conceivable that the end portion 37 of the temple 20 is curved at least in sections such that, in a use state, it at least partially encircles the ear (not shown).

[0075] In the Fig. 4 / 5 In the specific embodiment shown, for example, four sections 31, 33, 35, 37 lie between the beginning 30 and the end 38. In alternative embodiments, fewer than four or more than four sections can be formed.

[0076] The end portion 37 is configured and formed, at least in sections, to couple with the behind-ear element 40. The behind-ear element 40 can be connected to the bracket 20 via the end portion 37.

[0077] In some embodiments, the bracket 20 may further comprise at least one coupling element 26. The coupling element 26 may, for example, and preferably, be formed in the form of an opening in the bracket 20. The coupling element 26 may also be formed as an additional element, for example, as a loop or eyelet that is integrally formed on the bracket 20 (not shown).

[0078] The at least one coupling element 26 is configured and designed to couple the headband 60 to the bracket 20 as an additional connecting element. The coupling element 26 can be arranged on all sections 31, 33, 35, 37 of the bracket 20. Preferably, the coupling element 26 is arranged in section 35 and / or in the end section 37.

[0079] In a specific embodiment, the coupling element 26 can be formed by a recess in the material of the bracket 20 (see Fig. 4 ). The headband 60 can be passed through the coupling element 26. For this purpose, the coupling element 26 is preferably designed to complement the shape of the headband 60. For example, the coupling element 26 is minimally wider than the headband 60 is wide and minimally higher than the headband 60 is thick.

[0080] The bracket 20 is preferably formed from at least one rigid, stiffening material that nevertheless exhibits a certain degree of flexibility. The bracket 20 should exhibit a certain degree of rigidity while simultaneously maintaining flexibility in order to provide the connecting element 10 with sufficient overall stability while still allowing flexible engagement with the head 95.

[0081] In a simple embodiment, the bracket 20 can be made of a single material forming a single layer. In some embodiments, it is also possible for the bracket 20 to be constructed from multiple layers.

[0082] The bracket 20 can be made of plastic, metal, silicone, foam, and / or a composite material. The base material of the bracket 20 can be, for example, hard plastic and / or rigid plastic. For example, the bracket 20 is made of polypropylene.

[0083] The bracket 20 can have additional reinforcing and / or flexible and / or deformable elements in a base material, at least in certain regions. For example, wire, inorganic and / or organic reinforcing fibers, short and / or long fibers, rods, strips, fabrics, braids, grids, and / or structural mats can be additionally arranged in a plastic base material.

[0084] In some embodiments, the bracket 20 can be designed as a deformable element that can be individually adapted to the shape of the head. For example, the bracket 20 can be formed from at least one wire made of a wrought alloy, for example, a wrought aluminum alloy. Other materials with deformable properties are also conceivable, for example, plastics such as thermoplastics or the like. In an alternative embodiment, the bracket 20 can be formed from a composite material, preferably from a hard plastic and silicone and / or from a hard plastic and a thermoplastic elastomer (TPE).

[0085] The bracket 20 is not limited to these embodiments. Any materials that have reinforcing and / or stiffening and / or flexible properties are conceivable. In a simple embodiment, the bracket 20 can be made from only one of the above-mentioned materials or material composites.

[0086] In some embodiments, the bracket 20 can additionally be surrounded at least partially by a textile. The textile can increase the wearing comfort of the bracket 20. Possible textiles can be cotton, silk, and / or synthetic fibers such as polyester, polyurethane, neoprene, spandex, and / or nylon. Blended fabrics are also conceivable. Other materials that appear suitable in terms of biocompatibility, comfort, stability, elasticity, and cost are also conceivable.

[0087] Alternatively or additionally, the temple 20 can have a cushioning material, at least in some areas. The cushioning material can be made, for example, from foam, cotton wool, fabric, cotton, wool, rubber, neoprene, gel, and / or other elastic and / or viscoelastic materials. The cushioning material can increase wearing comfort and / or make wearing glasses more pleasant.

[0088] Fig. 6 bis 9 show views of the connecting element 10 from Fig. 3 , where Fig. 6A a view of the connecting element 10 from above, Fig. 6B a view of the connecting element 10 in an application state on the head 95 of a user from above, Fig. 7 a perspective view of the connecting element 10, Fig. 8 a view of the connecting element 10 from the side and Fig. 9 show a view of the connecting element 10 from the front.

[0089] The temples 20 can be straight and / or bent or curved in the x / z coordinate system. Preferably, at least one curvature and / or bend of the temple 20 is located within the x / z coordinate system. Due to the bend or curvature of the temples 20 in the x / z coordinate system, the temples 20 can extend from the patient interface 90 to the ears and can be adapted to the head shape of the user and / or patient. Due to the bend or curvature of the temples 20 in the x / z coordinate system, the connecting element 10 can be narrower on the patient interface 90 than in the areas that rest against the head 95 of the user in the application state (see Fig. 6B ). Due to the bend or curvature in the z-direction, the end 38 of the bracket lies above and / or below the beginning of the bracket 30.

[0090] Sections 31, 33, 35, 37 can be straight and / or bent or curved in the x / z coordinate system. All sections 31, 33, 35, 37 can be bent or curved in the x / z coordinate system. In some embodiments, only some or only one of sections 31, 33, 35, 37 can be bent or curved in the x / z coordinate system.

[0091] In the concrete embodiment according to Fig. 6 At least one section of the bracket 20 is bent or curved in the x / z coordinate system. For example, section 31 is curved at an angle β in the x / z coordinate system. The inflection point 32 is then located above the inflection point 34 in the z direction. The angle β is in a range from 120° to 180°. For example, the angle β is in a range between 130° and 170°.

[0092] The bracket 20 is preferably bent or curved at least in sections between the beginning 30 and the end 38 in two planes, namely both in the x / y coordinate system and in the x / z coordinate system.

[0093] The behind-ear element has a length L and a width B. In a simple embodiment, the length L may be equal to the width B. The ratio of the length L to the width B of the behind-ear element 40 may be 1:1 (not shown). In preferred embodiments, the ratio of the length L to the width B of the behind-ear element 40 may preferably be 5:1 or more.

[0094] Out of Fig. 6 and Fig. 7 It can be seen that the behind-ear element 40 in this embodiment is designed and constructed so long that it can extend from the end 38 of one temple 20 to the end 38 of the second temple 20. In a state of use, the behind-ear element 40 is arranged at the back of the user's head. In the embodiment according to Fig. 3 ff only a single rear ear element 40 is arranged on the temples 20.

[0095] The behind-ear element 40 has, for example, an elongated shape with two ends 44. The ends 44 can be shaped such that they form one or more retaining elements 42. The behind-ear element 40 can be coupled to the ends 38 of the two temples 20 via, for example, the two retaining elements 42. This coupling can be irreversible or reversible. This coupling can be movable or immovable. The length can be adjusted by coupling the behind-ear element 40 and temple 20. Depending on the position of the retaining elements 42 on the temple 20, the connecting element 10 can be adjusted wider or narrower (see also further below).

[0096] The connecting element 10 can be in the Figuren 3 and 5 bis 8 illustrated embodiment, in addition to the bracket 20 and the behind-the-ear element 40, comprise a further element in the form of at least one headband 60.

[0097] The headband 60 can be attached to the bracket 20. The attachment can be detachable and / or non-detachable. Preferably, the headband 60 can be detachably attached to the bracket 20. The headband 60 can pass through the openings 26 of the bracket 20 to couple the headband 60 to the bracket 20.

[0098] The headband 60 may have an elongated, narrow shape. The length L of the headband 60 is substantially greater than the width B of the headband 60. The ratio of the length L to the width B of the headband 60 may range from 10:1 to 50:1. For example, the ratio of the length L to the width B of the headband 60 is at least 10:1. In some embodiments, the ratio of the length L to the width B of the headband 60 is at least 20:1. In a preferred embodiment, the ratio of the length L to the width B of the headband 60 is 28:1 or more. The headband 60 preferably has an elongated, narrow shape.

[0099] The width B of the headband 60 can be constant or varying. In one exemplary embodiment, the width B of the headband 60 can be constant. The width B of the headband 60 can be in a range between 1 and 50 mm, preferably in a range between 3 and 30 mm. Particularly preferably, the width B of the headband 60 is between 5 and 20 mm. In a specific embodiment, the width B of the headband 60 is substantially 12 mm.

[0100] The length L of the headband 60 can range between 150 and 500 mm. Preferably, the length L of the headband 60 is between 300 and 500 mm. In a specific embodiment, the length L of the headband 60 is, for example, 340 mm.

[0101] The headband 60 can be made of a textile. The material of the headband 60 is preferably soft and flexible. The headband 60 is particularly preferably designed to be stretchable. Possible textiles can be cotton, silk, and / or synthetic fibers such as polyester, polyurethane, neoprene, spandex, and / or nylon. Blended fabrics are also conceivable. Other materials that appear suitable in terms of biocompatibility, comfort, stability, elasticity, and cost are also conceivable.

[0102] In a simple embodiment, the headband 60 is made solely of a textile and is configured and designed to provide additional support and stability to the connecting element 10. Alternatively or additionally, the headband 60 may also comprise reinforcing and / or cushioning materials. This may be advantageous for increasing wearing comfort and / or making it easier to fit the head 95. For example, it is conceivable for the headband 60 to include reinforcing structures that provide the headband 60 in a shape that is optimal for the head shape.

[0103] The headband 60 may have a narrow, elongated shape with two ends 64 and two end regions 63. The two end regions 63 may account for up to 50% of the total length L of the entire headband 60. In preferred embodiments, the two end regions 63 together account for approximately 25% of the total length L of the entire headband 60. Fastening elements 62 may be arranged on one and / or both end regions 63 of the headband 60.

[0104] In some embodiments, both end portions 63 of the headband 60 may include one or more fastening elements 62. For example, the end portions 63 of the headband 60 may include one or more hook-and-loop fasteners and / or hooks and eyes and / or buttons and buttonholes and / or snap fasteners and / or buckles or similar elements. These fastening elements 62 allow the headband 60 to be reversibly fastened to the one or more temples 20. The fastening elements 62 are configured and designed to allow for length adjustment of the headband.

[0105] The end regions 63 of the headband 60 preferably have one or more hook-and-loop fasteners. For this purpose, a hook-and-loop fastener with flexible barbs can be arranged on one or both end regions 63, which can form a resilient, secure, and reversible connection with the base material of the headband 60 (not shown).

[0106] To attach the headband 60 to the temples, the two ends 64 and the end regions 63 of the headband 60 can be passed through the openings 26 of the temples 20. The headband 60 can then be bent into a loop so that the end regions 63 can be connected to other regions of the headband 60 (see, for example, Fig. 7 ). Preferably, the connection can be held using a Velcro fastener.

[0107] It is also conceivable that at least one of the two ends 64 and / or end regions 63 of the headband 60 is irreversibly connected to one of the brackets 20 to protect against loss. Preferably, at least one of the two end regions 63 of the headband 60 is attached to the bracket 20 in a length-adjustable manner, as described above.

[0108] Fig. 10 shows a portion of the bracket 20 in various embodiments. Fig. 10 It is apparent that the end portion 37 of the bracket 20 can be designed differently towards the end 38. In some embodiments, the end portion 37 can have a constant width B ( Fig. 10A ). In alternative embodiments, at least a portion of the end section 37 can have a special design. For example, the end section 37 can be widened at least in sections compared to the generally constant width B. A widened end section 37 can be advantageous for attaching the behind-the-ear element 40 to the bracket 20.

[0109] The end section 37 can, for example, be widened at least in sections to form an anchor element 25. The anchor element 25 can be designed such that the end 38 is widened in an arrow shape ( Fig. 10B ). The arrow-shaped widening can effectively prevent the behind-the-ear element 40 from accidentally slipping off the temple 20. The anchor element 25 is not limited to the arrow-shaped configuration. For example, the anchor element 25 can also be circular, oval, and / or square. The anchor element 25 can also have any other suitable geometry that allows the coupling of the behind-the-ear element 40 to the temple 30 while simultaneously preventing accidental slipping.

[0110] Alternatively or additionally, the end section 37 of the bracket 20 may comprise one or more fixing elements 24 which may positively influence the attachment of the behind-ear element 40 to the bracket 20 ( Fig. 10C ). The fixing elements 24 on the temple 20 can be in the form of buttons, mushroom buttons, hooks, rods, rivets, hook-and-loop fasteners with barbs and / or loops, or the like. One or more corresponding counterpart elements, i.e., buttonholes, holes, eyelets, loops, hook-and-loop fasteners with barbs and / or loops, or the like, can be located on and / or at the ends 44 or end regions 43 of the behind-the-ear element 40 (not shown).

[0111] The fixing elements 24 can also be formed by one or more thickenings and / or notches or similar structures on the brackets 20, which allow a locking on the bracket 20 (not shown).

[0112] The attachment of one or more fixation elements 24 to a corresponding counterpart element can reinforce and / or secure the attachment of the behind-the-ear element 40 to the temples 20. The arrangement of several fixation elements 24 on the temple, located at different positions on the temple 20, can enable further length adjustment of the connecting element 10.

[0113] The arrangement of additional fixation elements 24 at the end section 37 of the bracket 20 can be particularly advantageous during positive pressure ventilation, since in this case a strong force acts on the connecting element 10. Additional fixation elements 24 can secure and stabilize the attachment of the behind-the-ear element 40 to the brackets 20.

[0114] Fig. 11 bis 14 show different embodiments for the rear ear element 40 of the connecting element 10 from Fig. 3 .

[0115] In the embodiment according to Fig. 3 ff, a single rear-ear element 40 is provided. The one rear-ear element 40 can be manufactured from one or more parts. In this specific embodiment, the rear-ear element 40 comprises at least two end regions 43. At least one central piece 45 can be formed between the two end regions 43.

[0116] The two end regions 43 can make up to 100% of the total length L of the entire behind-ear element 40, so that the behind-ear element 40 is formed without a center piece 45 (not shown). In alternative embodiments, a center piece 45 is formed between the two end regions 43, which can be of different lengths. For example, the two end regions 43 together can make up to 50% of the total length L of the entire behind-ear element 40, and the center piece 45 can make up the remaining 50%. The center piece 45 can also be shorter or longer.

[0117] In preferred embodiments, the end regions 43 constitute at most 25% or less of the total length L of the entire behind-ear element 40. The behind-ear element 40 can be coupled to the end sections 37 of the two temples 20 via its two end regions 43.

[0118] The center piece 45 may preferably constitute at least 50% of the total length L of the entire behind-ear element 40. In preferred embodiments, the center piece constitutes at least 75% or more of the total length L of the entire behind-ear element 40.

[0119] The length L of the rear ear element 40 is in the embodiments according to Fig. 11 bis 14 significantly greater than the width B of the behind-ear element 40. For example, the ratio of the length L to the width B of the behind-ear element 40 is at least 5:1. In some embodiments, the ratio of the length L to the width B of the behind-ear element 40 is at least 20:1. In a preferred embodiment, the ratio of the length L to the width B of the behind-ear element 40 is 30:1 or more. The behind-ear element 40 has in the embodiments according to the Figuren 11 bis 14 prefers an elongated, narrow shape.

[0120] The width B of the behind-ear element 40 can be constant or varying. In an exemplary embodiment, the width B of the behind-ear element 40 can be substantially constant ( Fig. 11 , 13 , 14 ). In some embodiments, the width B of the behind-ear element 40 can also be varied ( Fig. 12 ). The width B of the behind-ear element 40 can range between 0.2 mm and 30 mm. Preferably, the width B of the behind-ear element 40 is between 0.5 mm and 25 mm, particularly preferably between 7 and 25 mm.

[0121] The length L of the behind-ear element 40 can range between 50 and 400 mm. Preferably, the length L of the behind-ear element 40 is between 100 and 300 mm. In a specific embodiment, the length L of the behind-ear element 40 is, for example, 210 mm.

[0122] The behind-ear element 40 is preferably made of an elastic material. The behind-ear element 40 can be made of at least one material selected from the group consisting of silicone, thermoplastic elastomers (TPE), neoprene, or textiles. Possible textiles for the behind-ear element can be cotton, silk, and / or synthetic fibers such as polyester, polyurethane, neoprene, spandex, or nylon. The behind-ear element 40 is preferably made of silicone.

[0123] The behind-ear element 40 can be coupled to the temples 20. The behind-ear element 40 can comprise at least one, preferably two, retaining elements 42. The retaining elements 42 can be formed within the end regions 43 and / or formed by the end regions 43 (see Fig. 11 , 12 , 14 ). In alternative embodiments, the holding elements 42 can also be formed on the end regions 43 (see Fig. 13 ). The behind-ear element 40 can be coupled to the temples 20 via the holding elements 42. The holding elements 42 can preferably be coupled to the end sections 37 of the temples 20.

[0124] The coupling of the behind-the-ear element 40 to the temples 20 can be irreversible and / or reversible. In some embodiments, it is conceivable that one retaining element 42 is irreversibly coupled to one temple 20 and the other retaining element 42 is reversibly coupled to the second temple 20 (not shown). It is also conceivable that the behind-the-ear elements 40 are integral components of the temples 20 and / or that the temples 20 and behind-the-ear elements 40 are manufactured as a single piece.

[0125] The coupling of the behind-ear element 40 to the temples 20 is preferably reversible. The coupling of the behind-ear element 40 to the temples 20 can be movable and / or immovable. Preferably, the coupling of the behind-ear element 40 to the temples 20 is movable. By a movable coupling of the behind-ear element 40 to the temples 20, the positioning of the behind-ear element 40 within the connecting element 10 can be changed (see Fig. 8A und Fig. 8B ).

[0126] Fig. 11 shows a simple embodiment of the rear ear element 40 of the connecting element 10 from Fig. 3 , where Fig. 11 A a view from the side and Fig. 11 B shows a perspective view.

[0127] In the concrete embodiment according to Fig. 11 the length L of the middle section 45 can be up to 90% and the length L of the two end sections 43 together can be approximately 10% of the total length L of the behind-ear element 40. In the embodiment according to Fig. 11 The width B of the rear ear element 40 can be substantially constant. The width B of the middle piece 45 can be constant.

[0128] The end regions 43 can each be designed, at least in sections, as holding elements 42 in the form of elongated hollow bodies. The elongated hollow bodies can, for example, have a round and / or oval or angular cross-section. The elongated hollow bodies can be formed by connecting the end regions 43, at least in sections, along the length L to form a closed profile. The connection of the end regions 43 to form a hollow body can be achieved by sewing, welding, gluing, or the like, so that the end region 43 can have a connecting groove 48. The connection of the end region 43 to a hollow body is generally and preferably irreversible.

[0129] The retaining elements 42 configured in this way can be plugged onto the end sections 37 of the temples 20 (not shown). The end sections 37 of the temples 20 are then located, at least in sections, in the lumen 50 of the retaining elements 42. There, the retaining elements 42 hold the behind-the-ear element 40 under pretension by friction against the end sections 37 of the temples 20.

[0130] In order for the connecting element 10 to hold well on the head 95 of a user, the connecting element 10 must be set to a certain degree smaller than the circumference of the head 95. This allows a Zugkraft F The tensile force F is generally directed along the length L of the behind-ear band 40. In the embodiment according to Fig. 11 the holding elements 42 are in one plane with the center piece 45 along the tensile force F.

[0131] The holder can alternatively or additionally be formed and / or supported by fixing elements 24 and / or anchor elements 25 at the end sections 37 of the brackets (see Fig. 10 ). For this purpose, at least one end region 43 of the behind-the-ear element 40 can have at least one buttonhole or hole or eyelet or loop or a hook-and-loop fastener with barbs and / or loops or the like. In some embodiments, it is also conceivable for the end region 43 to have multiple buttonholes or holes or eyelets or loops or the like, so that length adjustment is possible (not shown).

[0132] Additional fixation offers the advantage that the behind-the-ear element 40 is firmly connected to the bracket 20 and that unintentional slipping on the bracket 20 can be prevented. This is particularly advantageous when using breathing masks 90 for positive pressure ventilation, since the tensile force F for sealing the breathing mask 20 via the behind-the-ear element 40 can be increased.

[0133] Fig. 12 shows a further embodiment of the rear ear element 40 of the connecting element 10 from Fig. 3 . The Fig. 12 The rear ear element 40 shown essentially corresponds to the one shown in Fig. 11 However, it is clear that the rear ear element 40 can be significantly longer in some embodiments. The rear ear element 40 can be up to 200% longer than previously described.

[0134] In this embodiment, the behind-ear element 40 may also comprise at least one eyelet 46. The eyelet 46 may have one or more openings 49 (see detailed view of the Fig. 12C ). The behind-ear element 40 can extend through the one or more openings 49 such that the middle piece 45 is formed into a loop, at least in sections. By moving the eyelet 46, the length L of the behind-ear element 40 can be adjusted. The behind-ear element 40 is thus inherently adjustable in length. The eyelet 46 holds the behind-ear element 40 through friction and / or pretension.

[0135] The eyelet 46 may alternatively or additionally include a spring mechanism and / or a locking mechanism (not shown). The spring mechanism of the eyelet 46 may comprise a spring and an actuating element. The spring mechanism can clamp the behind-the-ear element 40 in its position. The fixed position can be released by pressing on the actuating element to allow adjustment of the position of the eyelet 46 and thus a length adjustment. Fig. 12 The embodiment shown offers the advantage of a very flexible, simple, quick and safe length adjustment of the behind-the-ear element 40.

[0136] Fig. 13 shows a further embodiment of the rear ear element 40 of the connecting element 10 from Fig. 3 . In Fig. 13 Exemplary embodiments of the behind-ear element 40 are shown, in which the width B of the central piece 45 can be wider and / or narrower than the width B of the end regions 43. In these exemplary embodiments, the central piece 45 can make up approximately 50% of the total length L of the behind-ear element 40. In these exemplary embodiments, the end regions 43 together can make up approximately 50% of the total length L of the behind-ear element 40. The central piece 45 can also be shorter than shown.

[0137] Fig. 13 A shows a simple embodiment of a behind-ear element 40 with a substantially constant width B. Only the holding elements 42 are wider than the basic width B of the behind-ear element 40. Fig. 13 B bis D show that the middle piece 45 can be wider than the width B of the end regions 43. A wide middle piece 45 can have a positive effect on the comfort and stability of the behind-the-ear element 40.

[0138] Out of Fig. 13 It is further apparent that the holding elements 42 can be formed on the end regions 43. The holding elements 42 can be formed above and / or below the end regions 43. The holding elements 42 can also be designed such that they are arranged in a plane with the end regions 43 (see Fig. 11 , 12 , 14 ).

[0139] In the embodiments according to Fig. 13 The holding elements 43 are formed on the end regions 43 in such a way that the holding elements 42 are not in the same plane as the central piece 45 along the tensile force F. The tilting moment in the holding element 42 causes a stronger clamping and thus a better hold of the behind-the-ear element 40 on the bracket 20.

[0140] A further advantage of these embodiments is that the position of the behind-ear element 40 can be varied in the application state. The behind-ear element 40 can be rotated so that it runs in the neck (not shown) in an application state (see Fig. 8A ) or over the back of the head (not shown) (see Fig. 8B ).

[0141] Fig. 14 shows an alternative embodiment for the rear ear element 40 of the connecting element 10 from Fig. 3 .

[0142] The rear ear element 40 according to Fig. 14 can be made from several, for example two, production parts, which can be joined together to produce a finished component to form a behind-ear element 40. The two-part production can create a mechanism for length adjustment. The illustration in Fig. 14 A shows the rear ear element 40 in a partially disassembled state. Fig. 14 B-D shows the behind-the-ear element 40 in an assembled, ready-to-use state.

[0143] Fig. 14A shows that the behind-the-ear element 40 can be manufactured from two identically constructed parts. Each of the two parts contains an end region 43 with a holding element 42, a middle piece 45, and an eyelet 46. The eyelet 46 can be firmly connected to one end of the middle piece 45. The end region 42 can be firmly connected to the other end of the middle piece 45. The eyelet 46 can have at least one opening 49. The opening 49 can be arranged on one side in the eyelet 46. The opening 49 can be arranged on both sides in the eyelet 46 and form a through-channel through the eyelet 46.

[0144] The Fig. 14 B-D The assembled behind-ear element 40 shown in FIG. 1 shows that, in some embodiments, the behind-ear element 40 may include a length adjustment mechanism. To implement the length adjustment mechanism, the behind-ear element 40 may include at least two or more eyelets 46, 46i and / or two or more center pieces 45, 45i.

[0145] For the specific embodiment according to Fig. 14 The behind-the-ear element 40 preferably has two eyelets 46, 46i and two middle pieces 45, 45i. The first eyelet 46 can be firmly connected to the first middle piece 45. The second middle piece 45i can pass through the first eyelet 46 movably through the opening 49. The second eyelet 46i can be firmly connected to the second middle piece 45i. The first middle piece 45 can pass through the second eyelet 46i movably through the opening 49. Such a two-part embodiment enables simple and secure length adjustment of the behind-the-ear element 40. The behind-the-ear element 40 is thus inherently length-adjustable.

[0146] The eyelets 46, 46i hold the center piece 45, 45i, which passes through the opening 49 of the eyelet 46, 46i, through friction and / or pretension and / or via a spring mechanism. It is also conceivable that the center pieces 45, 45i have thickened portions that allow for a ratcheted length adjustment (not shown).

[0147] Fig. 15 shows a schematic side view of an alternative embodiment of the connecting element 10 according to the invention in an application state on the head 95 of a user. Fig. 16 bis 18 show different views of the connecting element 10 according to the invention from Fig. 15 , where Fig. 16 a view of the connecting element 10 from the side, Fig. 17 a perspective view of the connecting element 10, Fig. 18A a view of the connecting element 10 from the front and Fig. 18B show a view of the connecting element 10 from above.

[0148] In the alternative embodiment, the connecting element 10 comprises at least one bracket 20 and at least one behind-ear element 40. Preferably, the connecting element 10 comprises two brackets 20 and two behind-ear elements 40.

[0149] The connecting element 10 of the alternative embodiment according to Fig. 15 ff and the connecting element 10 according to Fig. 3 ff both comprise the temples 20 according to the invention, described in detail above. The temples 20 comprise the coupling system 22 for coupling to the patient interface 90 and the end section 37 for coupling the at least one behind-the-ear element 40. The coupling of the behind-the-ear element 40 to the temples 20 is preferably effected via the holding elements 42. The holding elements 42 can be designed and configured to allow length adjustment and / or to enable fixation and / or anchoring to the temple 20. A headband 60 is conceivable but not necessary in the alternative embodiment.

[0150] Out of Fig. 15 It can be seen that the connecting element 10 of the alternative embodiment in a state of use similar to the connecting element 10 according to Fig. 3 ff is arranged on the head 95 of a patient such that the bracket 20 is arranged at least partially between the nose and the ear. Here, the bracket 20 is located at least partially in the cheekbone region J. The bracket 20 is designed according to the embodiment described in detail above.

[0151] The alternative embodiment according to Fig. 15 ff differs from the embodiments according to Fig. 3 ff in the design of the rear ear element 40. In the embodiment according to Fig. 15 ff at least two behind-ear elements 40 are provided, each of which can be coupled to one of the at least two brackets 20.

[0152] The patient interface 90 can be designed as a high-flow interface, or HF interface for short. The patient can receive high-flow oxygen therapy, or HFOT for short, via the HF interface 90. HFOT represents a non-invasive form of respiratory support and / or respiratory therapy. With HFOT, oxygen and / or an oxygen-containing gas mixture can be supplied to the patient. The oxygen and / or the gas mixture can be applied at a very high gas flow of up to 60 l / min. The HF interface is usually designed as a nasal cannula and / or nasal prongs and can include nasal prongs 92. For example, the HF interface is designed as a nasal prong with at least one, preferably two, nasal prongs 92. The nasal prongs 92 (see Fig.16 ) can be inserted at least partially into the nose (not shown).

[0153] The Figures 19 and 20show embodiments of the behind-ear element 40 of the connecting element 10 according to the invention according to Fig. 15 ff. Contrary to the embodiments according to Fig. 11 to 14 the behind-ear element 40 can be shorter. The ratio of the length L to the width B of the behind-ear elements 40 can be less than 20:1, preferably less than 10:1, particularly preferably less than 5:1 in these embodiments.

[0154] Fig. 19 shows a simple embodiment of the behind-ear element 40 of the connecting element 10 according to the invention according to Fig. 15 , where Fig. 19 A a view from the side, Fig. 19 B a view from the front and Fig. 19 C shows a perspective view.

[0155] In the embodiment according to Fig. 15 ff, one back-ear element 40 is provided for each bracket 20. Preferably, the connecting element 10 has two brackets 20, each with a back-ear element 40. Fig. 19shows a behind-the-ear element 40 which, in a state of use, is arranged behind the ear (see Fig. 15 ). Out of Fig. 19 It can be seen that the length L of the behind-ear element 40 can be slightly greater than the width B. For example, the ratio of the length L to the width B of the behind-ear element 40 is less than 20:1, preferably less than 10:1, particularly preferably less than 5:1. The ratio of the length L to the width B of the behind-ear element 40 is, for example, approximately 3:1 in this specific embodiment.

[0156] In this specific embodiment, the behind-ear element 40 comprises a holding element 42. The holding element 42 is designed as a hollow body and comprises at least one lumen 50. The hollow bodies and the lumen 50 can, for example, have a round and / or oval or square cross-section. In some embodiments, the behind-ear element 40 can consist only of the holding element 42 (not shown). In alternative embodiments, the behind-ear element 40 can also comprise an end piece 41 ( Fig. 19 / 20 ).

[0157] To establish an application state, the behind-the-ear element 40 can be coupled to the temple 20. The coupling is effected via the holding element 42, which can be coupled to the end section 37 of a temple 20. Preferably, a behind-the-ear element 40 is coupled to each of the temples 20. The end section 37 of a temple 20 is then located at least partially in the lumen 50 of a holding element 42. There, the holding elements 42 hold the behind-the-ear element 40 under pretension by friction on the end sections 37 of the temple 20. The holder can alternatively or additionally - as described above for Fig. 10 described - are formed and / or supported by fixing elements 24 and / or anchor elements 25 on the end sections 37 of the temples and with corresponding counterpart elements on the behind-ear elements 40.

[0158] The coupling of the behind-ear elements 40 to the temples 20 can allow the connecting element 10 to be adapted to the respective head shape. The positioning of the behind-ear elements 40 on the end sections 37 of the temples 20 can preferably be variably adjustable. For smaller head shapes, the behind-ear element 40 can be moved on the temple 20 toward the beginning 30. For larger head shapes, the behind-ear element 40 can be moved on the temple 20 toward the end 38. This offers the advantage of very simple and quick size adjustment of the connecting element 10.

[0159] In contrast to the behind-ear element 40 according to Fig. 3 ff the rear ear element 40 runs according to Fig. 15 ff. in a state of use does not extend over the back of the user's head. Rather, the behind-the-ear element 40 is Fig. 15ff in a state of use arranged on and / or behind the ear. The behind-ear element 40 can be designed significantly shorter than in the embodiments according to Fig. 11 to 14 The length L of the rear ear element 40 can be varied by means of middle pieces 45 and / or end pieces 41 of different lengths.

[0160] The end piece 41 according to Fig. 19 / 20 can be made considerably shorter than the corresponding middle piece 45 of the embodiments according to Fig. 11-14 . Fig. 19 shows a behind-the-ear element 40 which, in a state of use, is arranged behind the ear (see Fig. 15 ). The length L of the end piece 41 can be in a range between 10 mm and 150 mm. Preferably, the length L of the end piece 41 is between 15 and 100 mm. In the specific embodiment according to Fig. 19 the length L of the end piece 41 is, for example, 32 mm.

[0161] Fig. 20shows alternative embodiments for the behind-ear element 40 of the connecting element 10 according to the invention according to Fig. 15 from the side. From Fig. 20 It can be seen that the end piece 41 of the rear ear element 40 can have different lengths L. Fig. 20 A shows a particularly short embodiment of a behind-ear element 40 with a total length L of 20 mm.

[0162] The rear ear element 40 can have different lengths L ( Fig. 20 AD ). For example, the behind-ear element 40 can be designed to be so long and curved that it surrounds the ear in a state of use (not shown) in such a way that the connecting element 10 is held in a particularly advantageous manner ( Fig. 20D). Fig. 20D shows a particularly long embodiment of a rear ear element 40 with a total length L of 150 mm. List of reference symbols
