Technical parameters and selection of catheter NTC temperature probe

　　Urinary catheter is a medical device that assists urination. There is a temperature measurement line in the body of the temperature measurement catheter. During catheterization, an external monitor can be used to monitor the temperature of the patient's bladder, which provides important information for the patient's pathological detection and minimally invasive surgery. guarantee.

　　The temperature measuring cavity in the catheter is equipped with an NTC temperature probe and a connecting wire. The NTC thermistor is located at the temperature measuring front end of the multi-functional cavity hose. It is connected to the connecting terminal through the connecting wire, and the output temperature and impedance are Signals are passed to the medical monitor through wires and connecting terminals. There is an insulating resin encapsulation layer on the NTC chip, which can reduce the heat capacity of the temperature sensing head and improve the sensitivity of the induction. When the temperature measurement catheter is inserted into the urethra to be measured, there is a head end with a developing mark on the top, and there is a layer of silica gel inflating the balloon on the outer wall of the catheter, which can be inflated and positioned at the required position.

　　Catheter accurate measurement: 0.1°C in the range of 25°C-45°C

　　Compatible monitor type: YSI400 series

　　Electromagnetic Compatibility (EMC) complies with industry standard IEC60601-1-2:2007

　　Resistor Type: NTC/YSI400/2.252K@25℃, NTC/Ohmeda/10K@25℃

　　Length: 900mm

　　Uses: Monitor urethral bladder temperature while catheterizing

　　Material: 100% made of silicon to prevent possible infections caused by latex

　　Features: Waterproof to prevent liquid backflow

　　It can be seen that, for the selection of NTC temperature probes, high precision, small size, simple structure, low cost and convenient use are required.
