- the patent WO2013 / 109329 A1 describes a three-layered polymer tube for a
- Infusion set with an outer layer of polyurethane, an inner layer of polyethylene and a
- the disadvantage is that the layer between the outer and the inner layer to the Patients can contaminate fluid to be dispensed. Further, it is disadvantageous that the inner layer of the tube can absorb preservative of the fluid to be delivered to the patient, so that the durability of the fluid to be delivered to the patient is limited.
- the invention is based on a multilayer tube for an infusion set.
- Such tubing may be used in conjunction with infusion sets to permanently or repeatedly deliver or deliver fluid to a patient.
- Infusion sets are commonly used in the treatment of diabetes, with permanent or repeated insulin being delivered to the patient.
- Multilayer tubes, in particular multi-layered tubes for infusion sets can also be used for other forms of therapy, whereby a permanent or repeated delivery of a fluid should be ensured.
- a first end of the tube of the infusion set may include an adapter for releasable connection to a fluid delivery device, in particular an infusion pump. Furthermore, a piercing cannula can be arranged on the adapter in order to form a fluid connection to the delivery device, in particular the infusion pump.
- the second end of the tube of the infusion set may include a cap with a piercing cannula, the piercing cannula may puncture a septum of a base of the infusion set to form a fluid communication between the tube and the base.
- the tube with the attached adapter and attached cap can form part of the infusion set.
- the base of the infusion set includes an adhesive patch that may be applied or adhered to the lumen of a patient and a cannula to deliver the fluid from the dispenser, particularly from the infusion pump, through the tube and cannula into the patient's body.
- the base may also form part of the infusion set.
- the inventive multilayer tube also in a different way to a
- Fluid delivery device in particular infusion pump detachably or permanently attached and / or connected in a different way with the patient, so that the fluid can be brought into the body of the patient.
- the invention relates to a multilayer tube for an infusion set for delivering a fluid.
- the cross section of the multilayered tube may be circular or oval in shape.
- the inner and / or outer surface of the multi-layered tube may have one or more grooves or ribs, in particular longitudinal grooves or longitudinal ribs.
- the multilayer tube has an outer and an inner layer.
- the outer layer comprises a polyurethane (PU) and the inner layer comprises a high density polyethylene (HDPE) or / and a polypropylene (PP).
- the multi-layered tube may comprise further layers, chemical or biological compounds or chemical or biological compounds in another layer.
- the tube may deliver preservatives, stabilizers or anti-inflammatory substances or other active ingredient to the fluid flowing through the tube.
- the multilayered tube preferably consists of two layers, in particular exclusively of two layers.
- the adhesion of the two layers to their mating surfaces preferably arises during the coextrusion process by a chemical and / or physical process.
- the outer and the inner layer can be connected to each other by a positive connection, adhesion and / or chemical bonding.
- the outer and inner layers of the multi-layered tube may be replaced by a
- the two-layer hose is produced by a coextrusion process, then cooled, for example, in a water bath, can be rolled up onto a roll and cut to the appropriate length.
- the two-layered hose does not include an adhesive layer between the outer and inner layers, the outer layer comprising a polyurethane (PU) and the inner layer comprising a high density polyethylene (HDPE) or a polypropylene (PP).
- PU polyurethane
- HDPE high density polyethylene
- PP polypropylene
- the absence of an adhesive layer between the two layers prevents the fluid to be delivered to the patient from being contaminated by a substance released from the adhesive layer.
- the multi-layered tube is transparent or transparent, so that the flowability of the fluid or a possible inclusion of air bubbles found, especially visually detected.
- the outer layer of the multi-layered hose comprises a polyurethane (PU), in particular a
- thermoplastic polyurethane PU
- PU thermoplastic polyurethane
- the polyurethane (PU) used should have a good tensile strength or a good tensile strength, a
- the outer layer of the multilayered hose particularly preferably comprises Elastollan® 1185A 10 FC from BASF Polyurethanes GmbH.
- the inner layer of the multi-layered hose comprises a high density polyethylene (HDPE) or / and a
- Polypropylene (PP).
- the High Density Polyethylene (HDPE) and Polypropylene (PP) used should be compatible with the fluid to be delivered to the patient so that, for example, between the fluid to be delivered to the patient and the inner layer of the multi-layered tube, there is as little or as little undesirable chemical-physical Reactions and / or interactions take place.
- the inner layer of the multilayer tubing comprises SABIC® HDPE B5429 from Sabic Europe or / and polypropylene Bormed TM SC820CF-11 from Borealis AG.
- the multilayer tube according to the invention can be used for an infusion set for the treatment of diabetes.
