Medical technology manufacturer Raumedic has developed two new wound treatment solutions for Lohmann & Rauscher, a medical and hygienic products specialist.
The solutions consist of a deep drainage solution and a drainage pad. Both of these devices are parts of the “suprasorb controlled negative pressure P3 therapy” which aims to support the healing process of internal and external wounds.
Silicone solution for deep drainage
The extrusion and handling of simple silicone tubes poses a certain challenge as a result of the material being used. The deep-drainage set contains a quadruple-lumen silicone tube, and this large inner lumen transports secretion, or exudate from wounds within the body, whilst the three small lumens in the tubing wall ensure that aeration can be actively managed during drainage. The company has filed a patent application for the solution.
Talking about the technology, Arno Herzele who is responsible for research and development for this therapeutic system at Lohmann & Rauscher said: “This special design is our unique selling proposition.”
Axel Wunderlich, product manager in applications technology, Raumedic commented: “You need lots of experience and technical know-how if the soft tubing wall should also have additional lumen, side drainage openings and X-ray contrast stripes.”
Kink-resistant drainage pad
Raumedic also works with Lohmann & Rauscher on a drainage pad for external wound therapy. As part of this technology which Raumedic manufactures for the organisation, wound secretion is transported via a port with an integrated aeration ring and a quadruple-lumen polyvinyl chloride tube. Wunderlich highlights how, “stability was a really important factor for us here.” He adds: “To achieve an optimal flow rate, the tube mustn't kink under any circumstances.”
