Problems solved by technology

[0007] A disadvantage of the listed non-absorbable as well as absorbable and / or biodegradable drug carriers is that the antimicrobial drug is immobilized by the selected composition and after implantation of the drug carrier the drug is no longer exchangeable by other drugs or supplement
In addition, drug release from all previous topical drug delivery systems is based on diffusion, thus releasing large amounts of drug only in the first few hours or days at best

Embodiment Construction

[0136] figure 1 and 5 To 14 show different illustrations of the first exemplary device according to the invention. figure 2 , 3 and 4 show three different exemplary embodiments of the present invention. Referring to the first exemplary embodiment, Figures 8 to 14 The workflow of the method according to the invention is shown, which can be easily applied according to Figures 2 to 4 other exemplary embodiments.

[0137] exist figure 1 and 5 The first exemplary device according to the invention shown in to 14 has an outer hose 1 on the front distal side in which openings 2 extending through the hose wall are arranged. The outer hose 1 consists of a plastically deformable material so that its shape can be adapted to the shape of the hollow space.

[0138] The outer hose 1 is connected at its distal first end 3 to an inner hose 4 which is coaxially arranged within the outer hose 1 . Internal hose 4 in figure 1 and 5 not shown, but in Figures 6 to 14 is visible in th...

Abstract

The invention relates to a medical device for local application of a fluid, comprising: a flexibly deformable outer hose comprising a plurality of through-openings, at least one through-opening being arranged in the region of a first end of the outer hose; flexible inner hose, the inner hose is at least partially arranged inside the outer hose, the outer diameter of the inner hose in the expanded state is at least equal to the inner diameter of the outer hose, so that it closes the opening of the outer hose, the inner hose The outer diameter of the tube can be transformed from an expanded state to a radially contracted state so that the opening is exposed; a connection structure firmly connects the outer hose and the inner hose to each other on the first end of the outer hose in a liquid-tight manner means to close them; and a connector for supplying fluid to the space between the outer hose and the inner hose. The invention also relates to a hose system for constructing such a device, and a method for operating such a device.

Description

technical field [0001] The present invention relates to a medical device for temporary topical administration of fluids, in particular pharmaceutical fluids. The invention also relates to a hose system for building a medical device of this type, a method for shortening a hose system of this type or a medical device of this type and a method for operating this type method of medical device. Background technique [0002] The topical administration of drugs, especially antibiotics, has been known for decades and has been time proven, especially in the treatment and / or alleviation of bone tissue infections. These agents can be subdivided into non-absorbable as well as absorbable and / or biodegradable pharmaceutical carriers. However, supplying fluid into the hollow space for flushing and sterilization purposes can also aid in the sterilization and cleaning of medical devices having hollow spaces that would otherwise be difficult to reach. [0003] Absorbable and nonabsorbable ...
