The invention relates inter alia to an apparatus for conveying and apportioning articles, preferably containers. The apparatus has a single-track conveyor region and a dual-track conveyor region, the latter being arranged directly downstream from the single-track conveyor region and having a first conveyor track and a second conveyor track. The apparatus has a distribution device which is configured to apportion articles, conveyed from the single-track conveyor region, to the first conveyor track and the second conveyor track. The dual-track conveyor region has a height-offset conveyor portion in which the first conveyor track is arranged higher than the second conveyor track. Advantageously, in the height-offset conveyor portion, articles still undistributed can be excited to move to the first conveyor track or the second conveyor track.

In one example embodiment, a system for treating a tissue site is disclosed comprising a dressing adapted to contact the tissue site and provide a fluid seal between a therapeutic environment and a local external environment, and a solution source fluidly coupled to the dressing and adapted to deliver an antimicrobial solution comprising a peroxy -keto carboxylic acid, such as peroxy pyruvic acid, to the tissue interface. The system may further comprise a negative-pressure source fluidly coupled to the dressing and adapted to provide negative pressure to the therapeutic environment after delivery of the antimicrobial fluid to the therapeutic environment. In another example embodiment, a method for treating a tissue site is disclosed comprising positioning a tissue interface to contact the tissue site, covering the tissue interface and the tissue site with a drape to provide a fluid seal between the therapeutic environment and the local external environment, and delivering an antimicrobial solution comprising peroxy -keto carboxylic acid to the therapeutic environment before providing negative pressure to the therapeutic environment.

A linear transport system includes a movable unit, a guide rail for guiding the movable unit, and a linear motor for driving the movable unit along the guide rail. The linear transport system also includes at least one switch having at least one static retraction element with a retraction motor module and a retraction rail element, and at least two static extension elements, each with an extension motor module and an extension rail element. The switch includes an exchange device having at least two exchange elements, each with an exchange motor module and an exchange rail element. In a first position of the exchange device, the retraction element is connected to a first extension element via a first exchange element. In a second position, the retraction element is connected to a second extension element via a second exchange element.
