Specialized dialysate lines refer to the specific type of tubing that is used to deliver dialysate, a solution that is used in hemodialysis, to a patient’s bloodstream. They typically consist of two tubes: an arterial line, which carries dialysate into the hemodialyzer, and a venous line, which returns the used dialysate back to the dialysis machine. Typically, our products are used to accommodate the tandem dialysis process whether it be in-series (straight line) or parallel (y-line).
They may have different features or materials, designed for specific patient needs or to meet certain clinical requirements. For example, dialysis adequacy targets are frequently difficult to achieve in large hemodialysis patients. Dual dialyzers can be used to improve clearance. In larger clients where standard methods of urea removal do not provide adequate dialysis, the increase in surface area of in-series or parallel dialyzers has accomplished this goal.
It is important for healthcare providers to select the appropriate type of dialysate line for each patient, based on their individual needs and clinical conditions. This helps ensure the safety and effectiveness of the dialysis treatment.
The principal function of the dialysate circuit is to prepare dialysate from concentrate and water and to deliver it to the dialyzer at the prescribed temperature and flow rate. The dialysate circuit is also used to control fluid removal from the patient.
Hemodialysis machines must be cleaned and disinfected regularly to prevent buildup of chemical and bacterial deposits in the dialysate flow path. Such deposits can interfere with conductivity-based monitoring systems and flow-meter–based ultrafiltration control systems.
The purpose of a dialysate recirculation set is to assist with cleaning and disinfecting by recirculating the dialysate for rinsing when the dialyzer is not present.
Ultimately, they help to improve the quality of the dialysis treatment by reducing the risk of infection and blood clotting in the dialysis lines. These also help improve the accuracy of the dialysis machine’s monitoring and control systems.
In hemodialysis, flow restrictors are commonly used in the dialysate line to regulate the flow of dialysate. This line makes it possible to variably control the rate of ultrafiltration and back filtration by adjusting the flow restrictor, making it possible to apply this treatment to a larger number of patients with a wide range of attainable blood flows. This also provides a method for individualizing the treatment for each patient. In short, it ensures that the correct amount of dialysate is delivered to the patient so it is safe, effective and consistent from one treatment to the next.
Lines that contain a flow restrictor enables the physician to prescribe treatments specific to the individual patient. This is done by providing a pressure differential for large ultrafiltration between two dialyzers to accommodate the tandem dialysis process in an in-series configuration.
Molded Products offers a variety of dialysate lines including disposable ones which are designed to be used once and then discarded, reducing the risk of contamination and infection.
After maximizing blood flow rate, dialysis flow rate, and dialyzer clearance, treatment time frequently remains a limiting factor given patient preferences and dialysis unit schedule limitations. Our specialized bloodline connectors and specialized dialysate lines are used together in conjunction with Dual dialyzers (in-series and parallel) which may offer patients another alternative to improve clearance without lengthening time.
Despite optimization of blood flow, treatment time, and dialysate flow rate, many large patients fail to receive adequate hemodialysis. A recent study examined the use of dual dialyzers as a method to improve urea clearance.
They do not have any ETO residuals, provide a sterile fluid path and are blood compatible.
