Abstract: An injection device includes a cylinder having a cavity for receiving a liquid. A passage is connected to the cavity for inflow and/or outflow of the liquid. The passage can be connected to an injection component. A shut-off valve has a valve body and a flexible sealing ring with an opening. The valve body, proceeding from a release position in which the passage is freed, is at least partially movable through the opening of the sealing ring to a blocking position in which the valve body engages behind the opening so that movement of the valve body to the release position is blocked and the passage is sealed off against proximally directed flow. An adapter body is connected to the cylinder. The shut-off valve is arranged at a proximal end of the adapter body and at a distal end of the cylinder. The device can be used in a syringe.

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.

Abstract: A piercing part for a medical infusion system includes a housing with a piercing mandrel, a fluid channel and a ventilation channel with a first channel portion extending at least substantially parallel to the fluid channel and with a second channel portion diverted towards an outside of the housing and to which an air filter element and a fluid shut-off member are assigned. A drip chamber can include a piercing part. The piercing part can be produced by an injection molding tool. The second channel portion in the housing is oriented parallel to the first channel portion and open towards an inside of the housing. An open region of the channel portion is closed by a separately produced closure part. The piercing part can be used with a medical infusion system.
