How to prevent the risk of temperature runaway in dialysis machines? Tongzida Medical PT1000 safeguards patient safety

The liquid temperature of the hemodialysis machine is directly related to the patient's life safety and needs to be stably controlled at 37 ± 0.5 ℃. Traditional sensors often cause equipment alarms and even medical risks due to disinfection corrosion and accuracy drift. The PT1000 sensor for dialysis machine is customized for medical scenarios and has become the core safety component of dialysis equipment with high stability and biocompatibility.

H2: Rigid requirements for temperature sensors in dialysis machines

The blood circuit and dialysate circuit of the dialysis machine require precise temperature measurement, and the sensors must meet the following requirements: measurement accuracy of ± 0.1 ℃, tolerance to high temperature sterilization at 134 ℃, biocompatibility (in accordance with ISO 10993 standard), and resistance to electromagnetic interference (suitable for hospital MRI and other equipment environments). The PT1000 sensor for dialysis machines perfectly matches these stringent requirements with its advantages of low self heating and high stability.

Precision drift prevention and control: using 3850PPM/℃ high temperature coefficient platinum deposition process, the PT1000 sensor dedicated to dialysis machine has a long-term stability of ≤ 0.04% drift for 1000 hours at 500 ℃, avoiding discomfort caused by temperature deviation in patients;

Sterilization environment tolerance: Medical grade stainless steel packaging, supporting ethylene oxide (EO) and high-pressure steam sterilization, with no performance degradation after repeated disinfection;

Biosafety assurance: All components that come into contact with bodily fluids have passed biocompatibility testing, are non-toxic, and have no allergenic reactions, ensuring patient safety;

Strong anti-interference ability: Through IEC 61000-4 electromagnetic compatibility testing, it maintains measurement accuracy even in strong electromagnetic environments in hospitals.

H2: Hospital test: Dialysis machine failure rate reduced from 8% to 0.5%

A certain tertiary hospital's dialysis center once used ordinary sensors, with a monthly equipment failure rate of 8%. After replacing the PT1000 sensor dedicated to the Tongzida dialysis machine, the failure rate dropped to below 0.5%, and the patient complaint rate was reset to zero. The stability of sensors directly improves the safety of diagnosis and treatment, and they are the 'security guards' of our department, "said the director of the dialysis department
