Description

Technical Field

[0001] This invention relates to a connector device, a patch, a tubing sleeve, and the use of the connector device. Background Technology

[0002] Connector devices for tracheostomy aids are well known in the art. EP2953674B1 discloses a tracheostomy patch having a container for a tracheostomy aid—such as a humidity exchanger or a sound valve—whereby the tracheostomy aid can be secured in the container by a clamping connection. Summary of the Invention

[0003] The object of this invention is to provide an improved connector device. A specific object of this invention is to provide a connector device for securely securing a tracheostomy support device. A further object of this invention is to provide a connector device capable of receiving a variety of different tracheostomy support devices.

[0004] According to the present invention, the above objective is achieved by a connector device for connecting a tracheostomy auxiliary device, wherein the connector device includes a connector ring, wherein the connector ring includes a first retaining ring and at least one second retaining ring, wherein the first retaining ring and the second retaining ring are formed on the inner surface of the connector ring, and wherein the first retaining ring and the second retaining ring have different inner diameters.

[0005] According to the present invention, the above objective is also achieved by a patch having the above-described connector device, wherein a connector is arranged on the distal side of the patch.

[0006] According to the present invention, the above objective is also achieved by a tracheal cannula with the aforementioned connector device, wherein a connector ring is arranged at the distal end of the cannula body.

[0007] According to the present invention, the above objective is also achieved by using the above-described connector device to connect tracheostomy auxiliary devices with different outer diameters.

[0008] This invention provides a connector device for connecting a tracheostomy auxiliary device, wherein the connector device includes a connector ring. The connector ring includes a first retaining ring and at least one second retaining ring. The first retaining ring and the second retaining ring are formed on the inner surface of the connector ring. The first retaining ring and the second retaining ring have different inner diameters.

[0009] During upper respiratory tract surgery, it may be necessary to create an artificial breathing opening in the trachea, known as a tracheostomy, so that air can bypass the mouth and larynx and be inhaled directly into the lungs. For patients who have undergone laryngectomy (losing their larynx through surgery), the tracheostomy must remain open and permanently fixed. For this purpose, a tracheostomy tube, typically consisting of an outer and inner tube, is usually inserted into the tracheostomy. However, a so-called "tracheostomy button" can also be used, especially for patients who no longer require a tracheostomy tube.

[0010] In addition, a so-called "shunt valve" can be inserted into the tracheostomy to restore voice function. Finally, a filtration system can be inserted into the tracheostomy in both tracheostomy and laryngectomy patients. This type of filtration system consists of a patch with an insertable filter, a usually self-adhesive connector, or a base plate, typically made of plastic, into which various types of filters can be inserted.

[0011] So-called "heat and moisture exchangers," also known as "artificial noses," are filtration systems used in laryngeal and tracheal support devices, such as tracheostomy tubes, shunt valves, tracheostomy buttons, and those with patches or base plates. Their function is to mimic the regulatory mechanisms missing in patients who have undergone laryngectomy and tracheostomy, to heat and humidify the air they breathe and to prevent the trachea from coming into contact with dry, cold, and unfiltered air. This is because contact with dry, cold, and unfiltered air can cause irritation, increasing mucus secretion and the risk of crusting. Now, the inhaled air is humidified, heated, and filtered through a heat and moisture exchanger. This greatly reduces the formation of crusts. Especially in cases of excessive secretions, frequent use of an artificial nose helps reduce secretion production because moisturizing the tracheal mucosa reduces secretion.

[0012] Moisture exchangers for patients undergoing laryngectomy and tracheostomy typically have a filter made of paper or foam material through which both inhaled and exhaled air are guided. During exhalation, the filter retains moisture, which is then delivered to the trachea during inhalation. Existing artificial noses, also known as "HMEs" (moisture exchangers), come in various designs to accommodate different adapters. According to DIN EN ISO 5356-1:2015-06, the standard adapters are of diameters of 15mm and 22mm, but larger diameter adapters, such as 16mm and 23mm, are also known in the art. For example, the 15mm or 16mm standard adapter is particularly suitable for tracheostomy tubes, while tracheostomy buttons and filtering systems, especially those with self-adhesive substrates or patches, have larger adapter diameters, such as 22mm or 23mm.

[0013] The tracheostomy support device can be, for example, a heat and moisture exchanger, a sound valve, or a combination of both. In one design, the tracheostomy support device, which can be received by a connector device, has an outer diameter of about 11 mm to about 25 mm in at least a portion of the area, preferably about 21 mm to about 24 mm, more preferably about 11.5 mm, more preferably about 15 mm, more preferably about 16 mm, more preferably about 22 mm, and more preferably about 23 mm.

[0014] The above exemplary examples should not be considered as an exhaustive description of the invention, but can be supplemented based on conventional expertise.

[0015] The advantage of the proposed connector device is that it can preferably receive tracheostomy aids of different sizes via at least two retaining rings. In particular, the connector device can receive at least one standardized tracheostomy aid and at least one non-standardized tracheostomy aid.

[0016] The connector assembly preferably includes a proximal connector. In one design, the connector assembly includes a connector formed as a substrate. In a preferred embodiment, the connector or substrate is a ring disk disposed on the outer wall of the proximal end of the connector ring. The connector preferably extends radially outward at the proximal end of the connector ring. An adhesive, such as an adhesive film, preferably with a peelable protective film, is preferably disposed at the proximal end of the connector or substrate. For example, the connector assembly with the adhesive then forms a tracheostomy patch.

[0017] In another design, a sleeve is specified at the proximal end of the connector ring. For example, the sleeve is a sleeve body. For example, the connector assembly and the sleeve body form a tracheostomy button or tracheostomy cannula.

[0018] If directional information is used in the description of this invention, it should be understood in accordance with the usual use of the connector device. Directional terminology adopts its conventional anatomical usage. For the purposes of this invention, with respect to the features of the device according to the invention, the term "distal" is understood to be positioned or used away from or opposite to or located relative to the tracheostomy band or tracheostomy cannula, more generally, and especially on the skin surface of a patient wearing the fastening device of the device according to the invention. Distal is preferably understood as a direction away from the patient's body. For the purposes of this invention, with respect to the features of the device according to the invention, the term "proximal" is understood to be positioned or used close to or facing or adjacent to the tracheostomy band or tracheostomy cannula, more generally, and especially on the skin surface of a patient wearing the fastening device of the device according to the invention. Proximal is preferably understood as a direction toward the patient's body.

[0019] The connector assembly includes a connector ring. The connector ring is preferably cylindrical. The connector ring preferably includes an outer sheath. More preferably, the connector ring includes an inner surface. The inner surface preferably extends from the proximal end of the connector ring along its inner side to the distal end of the connector ring. In one design specification, the connector is arranged proximal to the connector ring.

[0020] In one embodiment, the connector assembly, more preferably the connector element and / or connector ring, comprises a material selected from the group consisting of silicone, thermoplastic elastomers, and / or polyvinyl chloride. In one embodiment, the connector ring is made of the same material as the connector element. In another embodiment, the connector ring and connector element are connected by a material. For example, the connector ring and connector element are manufactured using one-component or two-component injection molding.

[0021] The connector ring includes a first retaining ring and at least one second retaining ring. In this invention, the retaining ring is understood as the first part of a snap-fit ​​connection. The snap-fit ​​connection includes functional elements for a simple form-locking connection of the connecting components, particularly the tracheostomy aid, to the connector assembly, both releasable and non-releasable. At least a portion of the connecting components thereby elastically deforms and subsequently interlocks, preferably in a releasable or non-releasable manner. At least a portion of the connector ring, retaining ring, and / or the tracheostomy aid is preferably elastically deformable. The first retaining ring and / or the second retaining ring may be formed in a fully circumferential manner in the connector ring. In one embodiment, the first retaining ring and / or the second retaining ring are formed in segments. The first retaining ring and / or the second retaining ring are particularly partially formed in a circumferential manner in the connector ring. The first retaining ring and / or the second retaining ring are preferably hooked together with the tracheostomy aid. The snap-fit ​​connection between the tracheostomy aid and the first retaining ring and / or the second retaining ring is preferably releasable. The tracheostomy aid and the connector assembly may preferably be connected in a form-locking manner. The connector ring preferably forms a ring-shaped snap-fit ​​connection with the tracheostomy support device. The connector ring is preferably formed as a snap-fit ​​cylinder. In one design, the connector ring is specified to have three or more snap rings. This allows for the reception of multiple different tracheostomy support devices.

[0022] The advantage of using a snap-fit ​​connection between the tracheostomy support device and the connector device is that the components can be easily connected together. However, after connection, the components are firmly connected to each other in a form-locking manner, ensuring that the tracheostomy support device will not detach from the connector device during use.

[0023] One design specifies that the connector ring has a first material thickness between the first and second retaining rings, and a second material thickness near the proximal end of the second retaining ring. This ensures functionality while maintaining sufficient stability.

[0024] In some tracheostomy support devices, a suitable groove for snap-fit ​​connection with a first or second retaining ring is not included. In this case, the retaining ring acts as a clamping ring. In one embodiment, the tracheostomy support device is clamped by either a first or second retaining ring, thereby achieving a clamping connection. Depending on the size or geometry of the tracheostomy support device, it is secured by either a clamping connection or a snap-fit ​​connection using a first or second retaining ring.

[0025] In this invention, the groove of the tracheostomy auxiliary device is understood to mean that the diameter of the tracheostomy auxiliary device or its conical connector gradually decreases in the opposite direction to the connection direction, so that the retaining ring can engage the rear part of the tracheostomy auxiliary device or the conical connector respectively.

[0026] In one embodiment, the first retaining ring and / or the second retaining ring includes at least one beveled distal end and / or proximal sliding surface. In the longitudinal section of the connector ring, the angle between the sliding surface and the centerline extending along the extension direction of the connector ring is preferably about 30° to about 50°, more preferably about 38° to about 48°, and even more preferably about 45°. The tracheostomy assist device can be advantageously and easily inserted into the connector ring via the sliding surface. In one design, the sliding surface is provided on the distal side of the first and second retaining rings, wherein the proximal side of the first and second retaining rings preferably does not have a beveled distal end and / or proximal sliding surface. The first and second retaining rings preferably include a distal surface that extends substantially in a plane perpendicular to the central axis of the connector ring. This advantageously simplifies the insertion of the tracheostomy assist device into the connector device, wherein after insertion and after engagement downstream of the first and second retaining rings, the tracheostomy assist device is not easily dislodged or cannot fall down, thereby achieving the connection of the two parts.

[0027] In the context of this invention, when the term "about" is used in conjunction with a numerical value or a range of numerical values, it should be understood as a tolerance range that is conventionally considered by those skilled in the art, particularly a tolerance range of ±20%, preferably ±10%, and more preferably ±5%. If the invention specifies different numerical ranges, such as preferred and more preferred numerical ranges, the lower and upper limits of the different numerical ranges can be combined with each other.

[0028] In one embodiment, only the second retaining ring includes a sliding surface. In one embodiment, only the first retaining ring includes a sliding surface.

[0029] In one design, a first retaining ring has a first maximum material thickness, and a second retaining ring has a second maximum material thickness, wherein the first maximum material thickness is less than the second maximum material thickness. The first minimum material thickness of the first retaining ring is preferably substantially the same as the second minimum material thickness of the second retaining ring. The first and / or second retaining rings preferably include a minimum material thickness on the inner edge of the ring, which is substantially located in the inner radial direction. More preferably, the first and / or second retaining rings include a maximum material thickness on the side facing the inner surface of the connector ring.

[0030] The sliding surface advantageously provides a simple connection between the tracheostomy accessory and the connector ring. The surface of the tracheostomy accessory, preferably a portion of its snap-fit ​​connection, can slide easily on the sliding surface in such a way that it can then be locked downstream of the first and / or second snap rings in the connection direction. Even if the tracheostomy accessory does not have a suitable geometry for locking the first and / or second snap rings into place, the sliding surface can still provide a simple connection between the tracheostomy accessory and the connector ring, where only a small force is required to adjust the tracheostomy accessory into the clamped position. Another advantage of the funnel-shaped sliding surface is that the tracheostomy accessory is centered when inserted into the connector ring.

[0031] The retaining ring is preferably formed as at least partially circumferential rings or as multiple ring segments. The first retaining ring and / or the second retaining ring preferably comprises a bead-like material stack. The first retaining ring and / or the second retaining ring are preferably designed in a funnel shape. In this invention, "funnel-shaped" is understood to mean, in particular, that the distal surface of the first retaining ring and / or the second retaining ring is oriented toward the central axis and inclined proximally. The first retaining ring and / or the second retaining ring are preferably designed as inwardly radially extending protrusions. The first retaining ring and / or the second retaining ring more preferably comprises an annular disk. In this invention, the distal and proximal surfaces of the first retaining ring and / or the second retaining ring are, in each case, substantially located in a plane perpendicular to the central axis of the connector ring. The distal and proximal surfaces of the first retaining ring and / or the second retaining ring are preferably arranged substantially parallel to each other. The distal or proximal surface of the first retaining ring and / or the second retaining ring is more preferably, in each case, substantially located in a plane perpendicular to the central axis of the connector ring.

[0032] The term "basic" refers to a range of tolerances that are considered economically and technically reasonable by those skilled in the art, so that the corresponding features can still be identified or realized.

[0033] In one embodiment, the proximal surface of the first retaining ring is arranged in a plane perpendicular to the central axis of the connector ring, and the proximal surface of the second retaining ring is designed in a funnel shape. In another design, the proximal surfaces of both the first and second retaining rings are designed in a funnel shape. In one embodiment, the proximal sides of the first and / or second retaining rings are substantially arranged in a plane perpendicular to the central axis of the connector ring. In one embodiment, the absolute value of the angle between the proximal side of the first and / or second retaining ring and the plane perpendicular to the central axis is specified as less than the absolute value of the angle between the corresponding distal side and the plane perpendicular to the central axis.

[0034] Specifically, the conical connector of the tracheostomy aid can advantageously slide on the distal side of the funnel-shaped or inclined surface of the first and / or second retaining rings, thereby applying a force to the connector ring from the distal side. This force deforms the connector ring, preferably to clamp the tracheostomy aid or engage it in a groove. When the tracheostomy aid or the conical connector has a groove, after the groove sweeps past the first or second retaining ring, the first and second retaining rings can spring back and form a reliable snap-fit ​​connection with the conical connector. When the tracheostomy aid is pulled out, the conical connector applies a force to the proximal side of the first or second retaining ring. When the proximal side of the first and / or second retaining rings is substantially arranged in a plane perpendicular to the central axis of the connector ring, or when the absolute value of the angle between the proximal side and the plane perpendicular to the central axis is less than the absolute value of the angle between the corresponding distal side and the plane perpendicular to the central axis, the pulling force required to remove the tracheostomy aid from the connector ring is significantly greater than the compressive force required to connect the tracheostomy aid to the connector ring.

[0035] The inner diameter of the first retaining ring and / or the second retaining ring is about 11 mm to about 25 mm, preferably about 21 mm to about 24 mm, more preferably about 11.5 mm, more preferably about 15 mm, more preferably about 16 mm, more preferably about 22 mm, and more preferably about 23 mm.

[0036] In one embodiment, the first retaining ring has a first inner diameter. In one design, the first inner diameter of the first retaining ring is specified to be approximately 16 mm or approximately 23 mm.

[0037] In one embodiment, the second retaining ring has a second inner diameter. The second inner diameter is preferably smaller than the first inner diameter. In one design, the second inner diameter of the second retaining ring is specified to be approximately 15 mm or approximately 22 mm.

[0038] In one embodiment, the first inner diameter of the first retaining ring is approximately 16 mm, and the second inner diameter of the second retaining ring is approximately 15 mm. In another embodiment, the first inner diameter of the first retaining ring is approximately 23 mm, and the second inner diameter of the second retaining ring is approximately 22 mm. The difference between the first and second inner diameters is preferably approximately 1 mm to approximately 2 mm.

[0039] In one design, a first retaining ring is specified to have a first inner diameter and a second retaining ring to have a second inner diameter, wherein the first inner diameter is larger than the second inner diameter.

[0040] In one design, the first clasp is positioned at the distal end of the second clasp. Tracheostomy aids with an outer diameter smaller than that of the first clasp can be advantageously guided through the first clasp and, in particular, can be connected to the second clasp in a form-locking or non-form-locking manner.

[0041] The second retaining ring is preferably positioned proximal to the first retaining ring. In one design, the first retaining ring is positioned distal to the connector ring. This allows the tracheostomy support device, which is clamped or snapped onto the first retaining ring, to be advantageously mounted on the second retaining ring.

[0042] In one embodiment, the connector assembly includes a respirator. The respirator more preferably includes at least one mesh, a mesh panel, and / or preferably an annular flange. In one embodiment, the respirator preferably includes at least a partially annular deposit of material inside the connector ring. The respirator is preferably designed as an annular or annular disc. The respirator advantageously prevents the tracheostomy support device from being over-inserted. The inner diameter of the respirator is preferably smaller than the inner diameter of the first and second retaining rings. The respirator is preferably disposed on the proximal end of the connector assembly, more preferably on the proximal end of the connector ring. The respirator is preferably designed to be substantially flush with the proximal side of the connector, especially when the connector is designed as a substrate. The respirator is preferably attached to the substrate material or made of the same material as the substrate. The respirator is preferably attached to the connector ring material or made of the same material as the connector ring.

[0043] In an exemplary embodiment of the connector device, it includes a connector. The connector is formed, for example, as a substrate of a patch. The connector is disposed, for example, on an adhesive element designed as an adhesive film. The connector extends radially outward along the proximal end of the connector ring. The connector ring is designed as a hollow cylinder and includes an inner surface. A first retaining ring and a second retaining ring are formed on the inner surface. The first retaining ring may be disposed, for example, at the distal end of the connector ring. The first retaining ring is designed, for example, as an annular disc and disposed flush with the distal end of the connector ring. The first inner diameter of the first retaining ring is, for example, about 23 mm. The second retaining ring is disposed near the proximal end of the first retaining ring and at approximately half its height along the central axis of the connector ring. The distal end of the second retaining ring includes a sliding surface at an angle of approximately 45° to the central axis of the connector ring. The proximal side of the second retaining ring extends, for example, in a plane perpendicular to the central axis of the connector ring. For example, the second inner diameter of the second retaining ring according to DIN EN ISO 5356-1:2015-06 is about 22 mm. A breathing apparatus is disposed on the proximal end of the connector ring. On the proximal side, the respirator is designed to be flush with the connector. The respirator is arranged in a ring-shaped disc on the inner surface of the connector ring. The connector ring, first retaining ring, second retaining ring, and connector are made of the same material.

[0044] An exemplary first tracheostomy support device, approximately 22 mm in diameter, according to DIN EN ISO 5356-1:2015-06, includes a tapered connector forming a groove that mates with a second retaining ring. In an exemplary process of connecting the first tracheostomy support device to the connector ring of the connector assembly, the first tracheostomy support device is guided through the first retaining ring without interacting with it because the first inner diameter of the first retaining ring is larger than the maximum outer diameter of the tapered connector. During further connection, the tapered connector is guided, for example, through a second retaining ring, where either the second retaining ring or the connector ring undergoes elastic deformation. After the groove of the tapered connector sweeps past the second retaining ring, the second retaining ring, for example, substantially springs back to its original shape and secures the first tracheostomy support device in the connector assembly in a form-locking manner. The connection of the first tracheostomy support device is limited proximally, for example, by a respiratory protective device positioned at the height of the connector.

[0045] An exemplary second tracheostomy support device has a tapered connector with an outer diameter larger than that of the first tracheostomy support device. During the connection of the second tracheostomy support device to the connector ring, the tapered connector is guided through a first retaining ring, causing either the first retaining ring or the connector ring to elastically deform. After the groove of the tapered connector sweeps past the first retaining ring, the first retaining ring substantially springs back to its original shape, securing the second tracheostomy support device in the connector device via a form-locking mechanism. The second tracheostomy support device can be positioned on a second retaining ring, thereby limiting excessive movement of the second tracheostomy support device within the connector device.

[0046] An exemplary third tracheostomy support device, approximately 22 mm in diameter, according to DIN EN ISO 5356-1:2015-6, includes a tapered connector that does not form a groove. In an exemplary process of connecting the third tracheostomy support device to the connector ring of the connector assembly, the third tracheostomy support device is guided through the first retaining ring without interacting with it because the first inner diameter of the first retaining ring is larger than the maximum outer diameter of the tapered connector. During further connection, the tapered connector is guided, for example, through a second retaining ring, where either the second retaining ring or the connector ring undergoes elastic deformation. The connection ends when the second retaining ring creates frictional resistance with the outer surface of the tapered connector, and the user perceives this frictional resistance as sufficient to achieve clamping. Optionally, the connection ends when the force applied to the third tracheostomy support device onto the connector ring exceeds approximately 50 N. The connection of the first tracheostomy support device is limited proximally, for example, by a respiratory protective device positioned at the height of the connector.

[0047] Furthermore, a patch with the aforementioned connector arrangement is proposed, wherein the connector is disposed on the distal side of the patch. The patch preferably includes an adhesive applied proximal to the connector. For example, the adhesive is designed as an adhesive film. In one design, the adhesive or adhesive film is specified to protrude over the connector on at least one side, preferably on all sides, within the plane in which the adhesive is disposed.

[0048] Furthermore, a tracheal cannula with the aforementioned connector device is proposed, wherein the connector ring is arranged on the distal end of the cannula body. The tracheal cannula can be designed as an inner cannula or an outer cannula. The cannula body can be designed with a window, a screen, or no window.

[0049] In addition, an application of the aforementioned connector device is proposed for connection to tracheostomy aids with different outer diameters. Attached Figure Description

[0050] Further advantageous designs are derived from the following figures. However, the further developments shown in the figures should not be construed as limiting; on the contrary, the features described in the figures can be combined with each other or with the aforementioned features to form more designs. Furthermore, it should be noted that the reference numerals specified in the description of the figures do not limit the scope of protection of the invention, but only refer to the exemplary embodiments shown in the figures. In the following text, the same components or components having the same function have the same reference numerals, wherein: Figure 1 A perspective view of the patch with connector assembly is shown; Figure 2 A longitudinal sectional view of the connector assembly is shown; Figure 3 Show Figure 2 Longitudinal sectional view of the connector device with the first tracheostomy auxiliary device; Figure 4 Show Figure 2 A longitudinal section view of the connector device with a second tracheostomy auxiliary device; and Figure 5 A tracheal sleeve with a connector assembly is shown. Detailed Implementation

[0051] Figure 1 A perspective view of a patch 34 with connector assembly 10 is shown. A connector 12 is formed as a substrate of the patch 34. The connector 12 is disposed on an adhesive 30, which is designed as an adhesive film with a peelable protective film. A connector ring 14 extends distally from the connector 12. The connector ring 14 is designed as a hollow cylinder and includes an inner surface 20. A first retaining ring 16 and a second retaining ring 18 are formed on the inner surface 20. The first retaining ring 16 corresponds to the distal end 32 of the connector ring 14. The second retaining ring 18 is disposed proximal to the first retaining ring 16 and is located approximately half its height along the longitudinal axis of the connector ring.

[0052] Figure 2 A longitudinal sectional view of connector assembly 10 is shown, not shown. Figure 1The patch 34 is shown. A first retaining ring 16 is formed flush with the distal end 32 of the connector ring 14. The first inner diameter 22 of the first retaining ring 16 is approximately 23 mm. The first retaining ring 16 includes a first maximum material thickness 62. A second retaining ring 18 is further formed generally centrally on the inner surface 20 of the connector ring 14. The distal end of the second retaining ring 18 includes a sliding surface 40 at an angle of approximately 45° to the central axis 42 (this angle is not shown in the figure for clarity). The second retaining ring 18 includes a second material thickness 64, wherein the first maximum material thickness 62 is less than the second maximum material thickness 64. According to DIN EN ISO 5356-1:2015-06, the second inner diameter 24 of the second retaining ring is approximately 22 mm. A respirator 38 is arranged on the proximal end 36 of the connector ring 14. On the proximal end 36, the respirator 38 is formed flush with the connector 12. The respirator 36 is arranged in an annular disc shape on the inner surface 20 of the connector ring 14. The connector ring 14, the first retaining ring 16, the second retaining ring 18, and the connector 12 are made of the same material.

[0053] Figure 3 Show Figure 2 The longitudinal section of the connector assembly 10 shows a first tracheostomy aid 50 with a diameter of approximately 22 mm, according to DIN EN ISO 5356-1:2015-06. The first tracheostomy aid 50 includes a tapered connector 58 forming a groove 60 that mates with a second retaining ring 18. During the connection of the first tracheostomy aid 50 to the connector ring 14, due to... Figure 2 As shown, the first inner diameter 22 of the first retaining ring 16 is larger than the maximum outer diameter 54 of the conical connector 58, so the first tracheostomy aid is guided through the first retaining ring 16 without interacting with it. During further connection, the conical connector 58 is guided through the second retaining ring 18, causing either the second retaining ring 18 or the connector ring 14 to elastically deform. After the groove 60 of the conical connector 58 sweeps past the second retaining ring 18, the latter essentially springs back to its original shape and secures the first tracheostomy aid 50 in the connector assembly 10 via a form-locking mechanism. The connection of the first tracheostomy aid 50 is limited proximally by a respiratory protective element 38 positioned at the height of the connector 12.

[0054] Figure 4 Showing a device with a second tracheostomy support 52 Figure 2The diagram shows a longitudinal sectional view of the connector assembly 10. The second tracheostomy aid 52 has a tapered connector 58 with an outer diameter of 56. The outer diameter 56 of the second tracheostomy aid 52 is larger than the outer diameter 54 of the first tracheostomy aid 50. During the connection of the second tracheostomy aid 52 to the connector ring 14, the tapered connector 58 is guided through the first retaining ring 16, causing either the first retaining ring 16 or the connector ring 14 to elastically deform. After the groove 60 of the tapered connector 58 sweeps across the first retaining ring 16, the latter essentially springs back to its original shape, securing the second tracheostomy aid 52 in the connector assembly 10 via a form-locking mechanism. The distal end 66 of the second tracheostomy aid 52 can be supported on the second retaining ring 18, thereby limiting excessive movement of the second tracheostomy aid 52 within the connector assembly 10.

[0055] Figure 5 A tracheal cannula 70 with a connector assembly 10 is shown. The tracheal cannula 70 is formed as an inner cannula and has a window 74. As described in the general description, the tracheal cannula can also be designed without a window, with a screen, and / or with an outer cannula. At the distal end of the cannula body 70, the tracheal cannula 70 has a connector assembly 10 with a connector ring 14. The connector ring 14 includes a first retaining ring 16 and at least one second retaining ring 18, wherein the first retaining ring 16 and the second retaining ring 18 are formed on the inner surface 20 of the connector ring 14. The first inner diameter of the first retaining ring 16 is approximately 23 mm, and the second inner diameter of the second retaining ring is approximately 22 mm according to DIN EN ISO 5356-1:2015-06.

[0056] The proposed connector device 10 can advantageously receive tracheostomy aids 50 and 52 with different nominal sizes. The connector device can be used in a particularly advantageous manner with tracheostomy aids 50 conforming to DIN EN ISO 5356-1:2015-06 and non-standard tracheostomy aids 52.
