Priorto begins by installing the Hemodialysis System in each treatment station, configured with online clearance monitoring (OCM), blood volume monitoring (BVM), and automated pressure tracking. The system’s hydraulic circuit uses a volumetric ultrafiltration controller with an accuracy of ±5 mL/h. A dualneedle configuration is standard, with a singleneedle option available for patients with difficult vascular access. Each system is integrated with the center’s electronic medical record (EMR) via HL7, automatically uploading treatment parameters every 15 minutes.

The Hemodialysis System’s OCM uses ionic dialysance to measure Kt/V in real time, displaying the result at 15minute intervals. The BVM monitors relative blood volume (RBV) change, triggering an alarm if RBV drops below 85% of baseline (indicating excessive ultrafiltration). The system’s venous pressure alarm is set at +50 mmHg from baseline; arterial pressure alarm at −100 mmHg. A blood leak detector (sensitivity 0.35 mL/min) is integrated into the dialysate outflow path.

The system’s touchscreen displays a colorcoded status indicator: green for normal operation, yellow for sensor drift requiring recalibration, red for critical alarm (e.g., blood leak, air embolism). A battery backup provides 20 minutes of operation during power interruption, allowing the blood to be returned to the patient safely. For facilities with multiple shifts, the system’s disinfection cycle (hot water at 90°C for 20 minutes) is automated to start 30 minutes after the last patient disconnect.

Technical Note: The OCM sensor requires daily zeropoint calibration using a reference dialysate solution; a missed calibration will produce Kt/V errors of up to 20%. The blood leak detector should be tested weekly with a 1:10,000 dilution of blood in saline; the system must alarm within 10 seconds.

Priorto installs the Dialysis Chair at each station, configured with electric height adjustment (45–80 cm), programmable reclining (backrest 0–70°, leg rest 0–45°), and a side table with integrated scale. The chair’s upholstery is made of antimicrobial vinyl with a fluidrepellent coating. A fourpoint locking caster system prevents unintended movement during needle insertion. The chair is positioned with 120 cm clearance on the vascular access side to accommodate the dialysis system and staff.

The Dialysis Chair’s electric actuators are rated for 200 kg patient weight, with a safety factor of 1.5. The hand pendant features largebutton controls labeled with international symbols for height, backrest, and leg rest. A memory function stores three positions: treatment (semireclined), emergency (Trendelenburg 15°), and exit (fully upright with leg rest lowered). For patients requiring extended dwell time (e.g., nocturnal dialysis), the chair’s pressure redistribution foam is specified to reduce the risk of pressure ulcers.

The integrated side table supports a 10 kg load and includes a recessed area for a cup holder and a clip for the blood pressure monitor hose. A USB charging port (5V, 2.4A) is embedded in the table for patient devices. The chair’s armrest on the access side is detachable, providing unobstructed access to the arteriovenous fistula or graft. For pediatric patients, a smaller chair model (35–65 cm height, 50 kg weight limit) is available.

Technical Note: The Dialysis Chair’s antimicrobial upholstery should be cleaned with a quaternary ammonium disinfectant after each patient; bleachbased cleaners will degrade the coating. The chair’s weight capacity is tested at 1.5 times the rated load; exceeding the limit will void the warranty and may cause actuator failure.

Priorto sells a full line of dialysis products. These products include dialyzers, bloodlines, fistula needles, and dialysate concentrates.

The inventory system runs in real time and uses RFID tracking. Patient prescriptions are saved in the electronic medical record. Each prescription contains dialyzer type, blood flow rate, and dialysate formula. At the start of each treatment, the system checks the chosen consumables against the prescription. If the dialyzer does not match, an alarm sounds.

Priorto offers high flux dialyzers with polysulfone membranes and low flux dialyzers with cellulose triacetate membranes. Surface area ranges from 0.8 to 2.5 square meters. For patients with heparin induced thrombocytopenia, a heparin free dialyzer with a special coating is available.

Bloodlines come in pediatric and adult versions. Pediatric bloodlines have a 50 milliliter prime volume. Adult bloodlines have a 120 milliliter prime volume. Both include arterial and venous pressure pods.

Fistula needles have a triple facet bevel for smoother insertion. They come in sizes from 17 to 25 gauge.

The dialysate concentrate system uses a central manifold for acid and bicarbonate. Each dialysis station has its own proportioning unit. The conductivity monitor is calibrated daily to 14.0 milliSiemens per centimeter at 25 degrees Celsius.

For patients who need custom sodium or potassium levels, a modular cartridge system allows mixing at the bedside.

The system tracks consumable inventory by weight. When dialyzer stock falls below a two day supply, the system automatically sends an order to the distributor.

Technical note: The high flux dialyzer has a prime volume that is 15 percent lower than a low flux dialyzer with the same surface area. This helps reduce the risk of intradialytic hypotension. Staff should rotate fistula needle insertions among three sites to prevent aneurysms. The system logs each needle’s lot number and recommends the next insertion site based on a rotation schedule.

Priorto installs a reverse osmosis (RO) water treatment system sized for the dialysis center’s peak flow demand (5 L/min per station × number of stations × 1.2 safety factor). The RO system includes a prefilter (5 μm sediment), carbon tank (chlorine removal), water softener, and a dualstage RO membrane array. Treated water quality is monitored continuously for conductivity (<5 μS/cm), total chlorine (<0.1 ppm), and bacterial count (<0.1 CFU/mL). A bypass loop returns unused water to the storage tank, maintaining flow even when no station is active.

The RO system’s conductivity alarm is set at 10 μS/cm, triggering an automatic shutdown and switch to a backup water supply. The carbon tank’s chlorine removal capacity is tested daily using a colorimetric test strip; a result >0.1 ppm initiates an immediate carbon tank regeneration. The water softener’s hardness is checked weekly; a hardness >1 gpg triggers a brine regeneration cycle. The bacterial monitoring program requires monthly culture samples from the RO loop, with action limits at 1 CFU/mL (warning) and 10 CFU/mL (recall).

The dialysate preparation system is integrated with the RO system, delivering ultrapure dialysate to each station. A central proportioning unit mixes acid and bicarbonate concentrates with RO water, targeting a final conductivity of 14.0 ± 0.2 mS/cm. Each station’s individual conductivity display allows the nurse to verify the value before connecting the patient. The system’s endotoxin filter (cutoff 0.01 EU/mL) is replaced every 100 treatment hours.

Technical Note: The dualstage RO membrane array reduces water consumption by 40% compared to singlestage systems, as the reject water from the first stage is fed to the second stage. The endotoxin filter must be integritytested after each replacement using a bubble point test; a failed filter will allow bacterial byproducts to enter the dialysate.

Priorto configures a central dialysis management dashboard that displays realtime status for all treatment stations. The dashboard shows each patient’s current ultrafiltration volume, treatment time remaining, venous pressure, and any active alarms. A colorcoded system (green, yellow, red) indicates stability. The dashboard is displayed on a 55inch screen in the nursing station and is accessible on mobile devices carried by each dialysis nurse.

The dashboard is integrated with the Hemodialysis System and the EMR. When a patient is seated, the nurse scans the patient’s wristband, and the system automatically loads the prescribed treatment (duration, ultrafiltration goal, dialyzer type). The dashboard then displays a countdown timer and a progress bar for fluid removal. If a patient experiences intradialytic hypotension (systolic BP <90 mmHg), the dashboard suggests a 30% reduction in ultrafiltration rate and displays a notification to the assigned nurse.

A treatment log is generated for each patient, including pre and postweight, blood pressure trends, Kt/V, and any alarms triggered. The log is automatically added to the patient’s EMR and printed for the patient’s file. For regulatory reporting, the dashboard aggregates centerwide metrics: percentage of patients achieving Kt/V >1.2, hypotension events per 100 treatments, and cannulation complication rates.

Technical Note: The dialysis management dashboard requires a dedicated server with 24/7 uptime; a redundant server with automatic failover is recommended for centers with >20 stations. The mobile app must be configured to receive push notifications even when the device is in donotdisturb mode; a special exception profile is created for nursing staff.
