Project Summary

Hemodialysis is a treatment that removes metabolic wastes from the blood in people who have renal failure or End Stage Renal Disease (ESRD). The Dialyzer, which works as a semipermeable membrane for the elimination of blood biochemical elements and occasionally excess water depending on the patient's state, is at the core of the purification process. These dialyzers are offered on the commercial market in two varieties: disposable and reusable, with the latter capable of repeated purifying cycles. A dialyzer is placed in the dialyzer reprocessing machine so that it may be used several times or cycles (DRM). A DRM will guarantee that the biological fluid is cleansed and disinfected using different fluids, and that it is filled with bacteria-repellent fluid for future use. Commercially, DRMs are becoming more costly. Our project aims to create a low-cost dialyzer reprocessing prototype that uses a RASPBERRY PI board for process control and uses R.O. Water, hydrogen peroxide, and formalin as cleaning and disinfection agents.

Project Objectives

The major goal of dialyser reprocessing machine is to reduce costs while maintaining the quality of dialysis and patient safety. We cannot afford to spend too much money on our health-care system as a developing country. So, the key advantages are lower costs and the ability to produce it locally in our nation, resulting in more jobs in our health-care system.

Project Implementation Method

Electronic components for instrument control are used throughout the reprocessing process. Power circuit (usually set up to run from a 9V/12V power source), RASPBERRY PI, and other materials are typical components of a development board and other materials. LEDs and other basic output circuits Led and solenoid valves are controlled by a 3 unit relay. The dialyzer was made with a 'Brovondove's Pristine BD 130 UNO' membrane that was semipermipermiable. The dialysis dialyzer has a total surface area of 1.3 m2. This is a controlled ultrafiltration hollow fibre dialyzer.Three submersible pumps with a pressure of 2.5 psi were utilised to pump the different fluids into the dialyzer. . Solenoid valves are used to regulate the flow of various fluids.SPST relays were utilised to open and close motors, as well as three solenoid valves. At 2.5Psi, R.O. Water was utilised to remove minute particles and blood stains from the dialyzer. The dialyzer was disinfected with hydrogen peroxide. During the storage phase, formalin was employed to keep germs at bay. A power supply that is connected to an appropriate electrical power source. RO water purifier tubing was used for tubing. Tubing was used to link three reservoirs of concentrated cleaning solution (R.O. Water, Hydrogen peroxide) and disinfection solution (formalin) to the valve. A RASPBERRY PI logic circuit was linked to the power source and configured to conduct a specified reuse operation cycle.

Benefits of the Project

The fundamental advantage of the dialyser reprocessing machine initiative is cost savings, however this should not come as a result of dialysis quality or patient safety. We cannot afford to spend too much money on our health-care system as a developing country. So, the key advantages are lower costs and the ability to produce it locally in our nation, resulting in more jobs in our health-care system.

Technical Details of Final Deliverable

Our final project consists of both hardware and software. A microcontroller is used to operate various electrical components, and the controller is programmed using a programming language. A thermal printer and scanner are also used to print and scan patient information.
