Our portfolio includes a high-quality selection of check valves for fluid management, such as Luer-actuated, needle-free and pressure-actuated valves with various opening pressures.

In addition, we offer Y-PTCA connectors for interventional angiography in "Tuohy Borst", "Push Pull" or "Push-Click" versions. They can also be supplied with an attached extension line terminated with a standard or high-pressure (45/500 psi) stopcock.

Specialty and regular Luer-activated valves provide one way maximum protection against backflow.


  • Haemostasis valve for catheter applications
  • Drug mixing of aggressive drugs
  • Pump ports and access ports for fluid lines (largely been replaced by needle free valves)

Needle free valves provide a simple two way valve that allow for easier access to pass fluids in external fluid systems. They also help to eliminate the risk of needle stick injuries.  


  • IV administration sets
  • Blood sampling lines
  • Invasive blood pressure monitoring lines
  • PICC / Midline catheter ports
  • Central Venous Catheter (CVC) ports
  • Total Intra Venous Anesthesia (TIVA)
  • Venipuncture closure
  • Endoscopy flush ports
  • Laparoscopic flush ports
  • Acts as a Luer activated valve

Dual Check Valves allows refilling from only the primary line and aspiration to only the secondary line. 


  • Waste protection stations
  • Saline / Contrast lines
  • Auto refill syringes 

Pressure-activated valves automatically close the fluid line below the opening (cracking) pressure and thus prevent the backflow of liquids. They are available with different Inlet- and Outlet options: Luer-to-Tube, Luer-to-Luer, Thread-to-Tube and Tube-to-Tube connections.

Check valves provide fluid control in one direction only.


  • Infusion Pump fluid delivery sets to prevent back flow
  • Infusion pump / gravity fluid sets to prevent back flow
  • Placing two in line check valves allows giving sets to be used patient to patient where clinical guidelines allow.

The PTCA connector allows easy insertion of PTCA guidewires and catheters with the possibility of one hand open and close operation. It enables a clean and safe application while minimizing backflow of blood.


  • Reduce blood loss during Percutaneous Coronary Interventions / diagnostics

Tuohy Borst Adapters provide secure closure around devices passed through the ports, alternatively they can minimize back flow during placement of devices.


  • Reduce blood loss on OEM catheters for applications like Atherectomy, thrombectomy, catheter ablation, external direct access catheter ports
  • Endoscopy port seals – reduce loss of fluid and gas.
  • Laser fibre access ports for varicose / peripheral vein closure.
