A delivery device comprises a first syringe, a second syringe, a needle or a tube, and a Y-connector that includes at least one access port.

A medical injection apparatus includes a first reservoir, a second reservoir, a static mixer, and an injection unit. The first reservoir contains a saline solution. The second reservoir contains medicine. The static mixer receives the saline solution from the first reservoir, receives the medicine from the second reservoir, and obtains a medical solution by mixing the medicine with the saline solution. The injection unit receives the medical solution from the static mixer and injects the medical solution into a skin of a subject.

The present disclosure relates to a tube insert for a dialysis liquid line or a hydraulic tubing set, the tube insert including at least one housing; a first connection point for connecting a tube section of the hydraulic tubing set to the tube insert; a second connection point for connecting a second tube section of the hydraulic tubing set to the tube insert; a third connection point for connecting a fluid receptacle to the tube insert; a main line in fluid communication with the first connection point and with the second connection point; a secondary line in fluid communication with the third connection point; and a deflection element for deflecting the liquid, or parts thereof, flowing in the main line out of the flow direction and towards the secondary line.

A catheter cap includes a housing defining at least one cavity and an opening at a distal end of the housing, and an antimicrobial agent within the at least one cavity. The housing is configured to couple to a catheter luer at the distal end. The at least one cavity is configured to contain a catheter lock solution in contact with the catheter luer at the opening. The antimicrobial agent is present in an amount sufficient to maintain a minimum inhibitory concentration (MIC) of the antimicrobial agent in the catheter lock solution for a period of time between successive operations of the catheter luer.
