Description

Technical area

The present invention relates to a holding device for the fixation of tracheostomy cannulas.

State of the art

Various holding devices for the fixation of tracheostomy cannulas are known from the prior art.

That's how it describes EP 1 454 601 A2 For example, an arrangement for external tracheostoma stabilization with a Tracheostomastabilisierungsring having on its outer periphery two coupling agents. To this coupling means, a soft carrying strap which can be guided around the neck of the wearer can be attached.

From the DE 20 2004 012 644 U1 is a tether for fixation of tracheostomy channels known. The length of this strap can be adjusted by Velcro fasteners individually to the respective patient, so that there is a good wearing comfort. The strap consists of a foam strip, which is coated with a velor layer and equipped with Velcro strips.

Furthermore, the describes DE 20 2005 012 609 U1 a holding device for the fixation of tracheostoma channels, wherein the retaining strap and a coupling means comprehensive holding device is at least partially made of cellulose.

The known from the prior art holding devices for the fixation of tracheostomy cannulas have a number of disadvantages. The laminated with skin-friendly materials foam strips are very expensive to manufacture. In addition, the foam discolored under the influence of light, thereby creating an aged, unclean impression, which is usually not accepted by the patients. In addition, the foam may contain various chemical constituents and, in particular, adhesives which lead to skin irritations in the wearer. Another disadvantageous aspect is the disposal of used holding devices. The non-decomposable materials are in fact problematic waste, which must be disposed of with increased financial expense.

The existing cellulose holding devices are only to a small extent resistant to moisture and moisture. In order to achieve the necessary stability, the cellulose must be processed multilayered or in multiple layers or combined with other stable, moisture-resistant materials.

Both high material consumption and expensive, extensive and multi-stage manufacturing processes drive up the costs of known holding devices. Therefore, there is still a need for easy and inexpensive producible and material saving fixtures.

Presentation of the invention

This is where the invention starts. The invention, as characterized in the claims, the object is based on providing a holding device for the fixation of tracheostomy cannulas available, which ensures a high level of comfort and at the same time can be inexpensively manufactured with simple, established methods.

This object is achieved by the holding device for the fixation of tracheostomy cannulas according to claim 1. Further advantageous details, aspects and embodiments of the present invention will become apparent from the dependent claims, the description, the examples and the figures.

The present invention provides a holding device for the fixation of tracheostoma cannulas comprising a coupling agent for fixed connection with a cannula and a variable-length holding strap detachably connectable with the coupling agent. The tether is formed at least in two parts and comprises a first and a second tether part, wherein each tether part is firmly connected to a respective terminal closure tape. At least one tether part is equipped with a connecting means for the fixed but detachable connection of the first tether part with the second tether part. Each tether part has at least one two-layered section consisting of a first and a second layer and at least one three-layered section comprising a third layer arranged between the first and the second layer. The first and second layers are made of a polypropylene nonwoven and the third layer is made of an elastomer.

A particular advantage of polypropylene nonwoven material is its high stability and durability. At the same time, the material is supple, soft and comfortable on the skin. Due to its properties, polypropylene nonwoven material can be used in the form of very thin layers without sacrificing stability or tear resistance. In contrast, this is not possible with other materials, such as cellulose. By using the polypropylene nonwoven Material will receive a thin holding device that does not apply and gives a very comfortable fit.

Stability and tear resistance as well as a comfortable fit remain even with a damp or wet condition of the material. For example, in the personal hygiene of the patient, a wetness of the holding device can hardly be prevented. Likewise, perspiration or possibly exuding wound exudate can moisten the material. If a holding device made of a non-moisture or water-resistant material, such as cellulose, this leads to a softening of the material or cracks and the holding device must be changed. The holding device according to the invention, however, remains stable even in the wet or wet state and gives the wearer security.

Polypropylene nonwoven materials are used as standard materials, above all in the diaper industry or baby hygiene but also in adult hygiene. Therefore, there are efficient, established manufacturing processes that can be easily adapted to the production of the holding device according to the invention. Women's diapers or feminine hygiene products are mass produced at an extremely high production rate. At the same high speed, the holding devices according to the invention can now be produced, resulting in a very cost-effective production.

Likewise, for example, made of the diaper industry semi-finished products can be used for production. Through optimized, adapted cutting patterns, the semi-finished products can be adapted so that as few sections or waste as possible, which contributes to a very low material loss and waste prevention. The accompanying saving in raw materials leads to a further cost reduction.

Due to the efficient and inexpensive production methods described above and the possible material savings when using a polypropylene nonwoven material, the manufacturing cost of the fixture is reduced by approximately 85% as compared to a retainer with laminated foam strips. Compared with a holding device made of cellulose, the production costs can be reduced by about 50%.

Each of the two holding strap parts provided according to the invention has at least one two-layered section consisting of a first and a second layer and at least one three-layered section comprising a third layer arranged between the first and the second layer. The first and second layers are made of a polypropylene nonwoven and the third layer is made of an elastomer.

Polypropylene nonwoven fulfills all stability requirements and ensures a high wearing comfort. Preferably, a "soft PP nonwoven" or a "special soft PP nonwoven" from Koester GmbH & Co. KG (Altendorf) is used.

Elastomers are dimensionally stable, under tensile and compressive load elastically deforming plastics, which return to relief in their original, undeformed shape. The elastane particularly preferably used is a block copolymer of polyurethane and polyethylene glycol. The elasticity of elastane is 500-700%.

The polypropylene nonwoven layers provide the high wearing comfort already described, while the third layer made of an elastomer is responsible for the elasticity of the tether. By the inventively provided two-layer section without elastomer layer, the extensibility of the tether is limited. In addition, these low elasticity portions are subject to little deformation when subjected to a tensile force. While the elastic portions taper at the same time as their extension in the direction of the tensile force acting perpendicular to the tensile force, the non-elastic portions change their dimensions under the action of a tensile force only slightly to not at all. The bearing surface in a certain area of the neck of the wearer or patient thus remains undiminished and an uncomfortable wearing feeling or even necking can thus be prevented.

Due to the described structure of the tether parts of two-layered and three-layered sections, only slightly stretchable regions on the one hand and elastic regions on the other hand result. On the side facing the body of the wearer, a layer of polypropylene nonwoven is provided in each case, a material that is extremely soft and hypoallergenic and gives a very comfortable fit. Due to the higher elasticity of the elastic portions of the tether parts, the entire tether adapts excellently to the neck of the wearer and ensures a secure hold of the tracheostoma cannula.

The elastic behavior of the entire tether may be varied by a combination of any number of elastic sections and any number of only slightly stretchable sections become. For this purpose, for example, the extent or the section size of the elastic sections and / or the only slightly stretchable sections can be changed.

According to the invention the tether is at least two parts and therefore variable in length. The tether is divided into at least two tether parts. The length of the tether can be adjusted individually to the needs of the patient, which leads to an increased wearing comfort. It is found to be particularly advantageous that, in contrast to the solutions known from the prior art, the same embodiment of the tether according to the invention can be used both for adults and for children.

According to the invention at least one tether part is provided with a connecting means for fixed but releasable connection of the first tether part with the second tether part. This is particularly preferably the hook part of a mechanical closure system. The connecting means is pressed with its surface having the hook on the surface of the second tether part. The hooks engage in the provided by the polypropylene nonwoven layer rough surface and cause a firm connection of the two tether parts. Since the hook surface of the connecting means is pressed in the direction of the carrier on the second tether part when using the holding device, the connecting means is advantageously provided on the surface facing the carrier when using the holding device with the hook part of the mechanical closure system.

Particularly preferably, the connecting means is glued to a tether part. As a result, a secure and permanent attachment of the connecting means is provided on this tether part. The connection with the second tether part via the hooks of the connecting means.

The described mechanical locking system for length-variable locking of the two tether parts multiple opening and closing operations can be accomplished easily.

Preferably, the two terminal fastener tapes with which the tether is equipped have tapered portions. The tapered portions are provided for releasable connection with the coupling means. The fastener tapes are for this purpose threaded with the tapered sections in two openings provided for receiving the fastener tapes openings of the coupling means. Since the coupling agent is firmly connected to the tracheostomy cannula, in this way a simple and fast connection of holding device and tracheostomy cannula is achieved.

Particularly preferably, the fastener tapes are provided on the surface of the tapered portions of the fastener tapes facing away from the wearer when using the holding device with the hook portion of a mechanical two-component locking system, wherein the hook portion is composed of at least two spaced apart hook portions. This ensures that the fastener tapes can be closed on the one hand with a simple handle and on the other hand a multiple closing and opening of the fastener tapes is possible. This allows an individual adjustment easily done and it is a simple and secure way to fix the straps created. In particular, by the use of at least two spaced-apart hook-part sections a secure attachment of the coupling means is ensured by the hook and loop system.

Advantageously, the loops are also formed as part of the fastener tapes and protrude at least in sections on a surface facing away from the wearer from the outer layer of the fastener tapes. According to a particularly preferred embodiment of the present invention, the loops are made of PET (polyethylene terephthalate). Particular advantages arise when the loop section is a so-called "frontal days", in particular a "frontal days" with the designation FT 800 R from Koester GmbH & Co. KG (Altendorf).

Due to the aforementioned section-wise arrangement of hooks and loops of the fastener tapes, it is particularly easy to bring the hook section and the loop section into contact with one another by folding over or folding back the fastener tapes and finally to effect closure. Preferably, as already described above, the fastener tapes are threaded into the openings of the coupling means and then folded back in order to bring hooks and loops into contact with one another and thus to fix the entire holding device.

Preferably, for example, a "closure day" from Koester GmbH & Co. KG (Altendorf), in particular the closure band designated as CP 2 MY 46, comes into question as a closure band.

Particularly preferably, the closure tapes are glued to the tether parts. This will ensure a secure and permanent attachment Secured fastener tapes to the tether parts.

Particularly preferably, the tether parts have a perforation in the form of microholes. This increases the air permeability and at least reduces sweating of the wearer.

In order to further improve the wearing comfort, a reinforcing part detachably connectable to the tether parts is additionally provided, wherein the reinforcing part is arranged in the neck region of the wearer when the holding device is used. The reinforcing member has a certain softness and also increases the contact surface of the tether on the skin of the wearer, whereby a more comfortable fit is effected.
