  • Patent number: 11395876
    Abstract: A pump module for an infusion pump includes a plunger-cylinder unit that can be coupled to the infusion pump in order to deliver fluid from a fluid feed line into a fluid drain line to a patient. The plunger-cylinder unit has a delivery chamber that is fluidically connected to the fluid feed line and the fluid drain line. The delivery chamber is delimited by the cylinder (14). The plunger can be moved linearly/back and forth in the axial direction. A plunger seal seals the plunger in relation to the cylinder. The section of the wall of the cylinder, over which the plunger seal passes during the back-and-forth motion of the plunger, is sealed in a sterile manner in relation to the surroundings.

  • Publication number: 20210187192
    Abstract: An infusion system includes a pump and a replaceable pump module. The pump module can be arranged in a mount of the pump and includes a plunger-barrel unit operatively connectable to a drive mechanism of the pump. The pump module includes a plunger that can be coupled to the drive mechanism by a coupling structure operatively connected to the plunger and a counter-coupling structure for connecting engagement in the coupling structure and operatively connected to the drive mechanism. In a securing position, the infusion system includes a securing member which locks the coupling structure and the counter-coupling structure to each other. In addition or in the alternative, the infusion pump includes a control link operatively connected to the pump module.

  • Patent number: 10899617
    Abstract: An apparatus is provided for treatment of process gas formed during nitric acid production by catalytic oxidation of NH3. The apparatus includes a reactor, a first catalyst bed for N2O decomposition, an absorption tower to react the NOx formed with an absorption medium downstream of the first catalyst bed, a device for adding NH3 added to tailgas entering the second catalyst bed, and a second catalyst bed for NOx reduction and further decrease in N2O in the tailgas exiting the absorption tower. The second catalyst bed contains at least one iron-loaded zeolite catalyst. N2O removal in the first catalyst bed is limited such that the process gas exiting the first catalyst bed exhibits a N2O content of >100 ppmv and a molar N2O/NOx ratio of >0.25. Treated gas exiting the second catalyst bed has a NOx concentration of <40 ppmv and a N2O concentration of <200 ppmv.
