they’re used, skin surface temperature monitoring also helps healthcare professionals in critical care settings, such as to: ■Determine the effectiveness of treatments;
■Monitor trends in patient condition; ■Make any necessary changes to treatment plans accordingly.
How do Amphenol Sensors meet skin surface temperature monitoring applications? Interchangeable thermistor assemblies with a temperature accuracy of for continuous patient monitoring and neonatal incubator systems.
Dialysis Temperature sensors are essential components of dialysis machines. They’re primarily used to measure the temperature of the dialysate (the solution that runs through the patient’s bloodstream to filter out toxins). If temperatures become too high or low, it can cause health problems such as hypothermia or overheating for the patient. Suffice it to say, by using temperature sensors to always monitor the dialysate temperature, the dialysis process is kept within safe parameters. Furthermore, some dialysis machines also use a series of heaters and coolers that can be regulated by temperature sensor readings to help maintain an optimal temperature range throughout treatment. This helps avoid any potential side effects caused by extreme temperatures during dialysis sessions. How do Amphenol Sensors meet dialysis applications? small interchangeable thermistors for assembly into metal housings used to monitor fluid temperature during dialysis.
Respiratory care
In ventilator flow tubes, the sensors measure the temperature of the air flowing through the tube. Air delivered to the patient needs to be at the correct temperature (98.6˚F) and humidity level to prevent damage to the patient’s airway and ensure that the patient is comfortable. If the air is too cold or too hot it can cause a host of issues, such as: ■Discomfort; ■Dry out the airway; ■Mucosal damage; ■Bleeding.
Adding moisture to the air, humidifiers are invaluable for treating patients with respiratory conditions such as asthma, COPD and cystic fibrosis. Just like the air in a ventilator flow tube, the water used in humidifiers needs to be at the appropriate temperature for the patient and to prevent bacteria growth. How do Amphenol Sensors meet respiratory care applications? Glass diode or epoxy-coated chip thermistors for temperature monitoring of ventilator flow tubes and humidifiers.
Thermometry
The measurement of body temperature, thermometry is the most general way to look at temperature monitoring. It also represents one of the most important metrics in patient critical care. Accurate medical temperature monitoring is essential for assessing the severity of illness, tracking patient progress, and guiding treatment decisions. How do Amphenol Sensors meet thermometry applications? Interchangeable thermistors and infrared (IR) temperature sensors for oral, rectal, tympanic and auxiliary temperature measurements.
Laser surgical assemblies Temperature sensors are essential for laser surgical assemblies, as they allow for the precise control of heat energy. With the high degree of control required for laser surgery procedures, surgeons can ensure that tissue is heated to a specific temperature, which minimises the risk of burning or damaging surrounding tissue or organs. Additionally, these sensors also help protect medical personnel from exposure to high levels of heat by alerting them when temperatures rise above their set threshold limit. In some cases, they can even shut down devices automatically in response to dangerous levels of heat. How do Amphenol Sensors meet laser surgical assembly applications? Miniature chip-in-glass or sleeved chip thermistors with fine diameter wires for insertion into hypodermic needles for myocardial surgeries and external attachment to metal lumens used during laser surgery.
Custom temperature sensor integration design considerations What’s the best temperature sensor for

your OEM medical device? The sensor that’s custom designed for it. Yet like all other sensors on the market – custom and off-the-shelf – temperature sensors have their own specific considerations to work through with your sensor manufacturer: ■Application temperature range: What are the minimum and maximum operating temperatures of the device the sensor is in? In addition, what are the minimum and maximum temperatures the sensor will be expected to measure?
■Temperature accuracy: How accurate does the sensor need to be over the range? As no two devices or applications are the same, the threshold for accuracy is not always the same. Think of it as the sensor’s tolerance level.
■Temperature consistency: Will the temperature the sensor’s monitoring constantly change or will it stay generally stable?
■Sensor lifespan: Is the sensor disposable or reusable? If it’s reusable, how is the device cleaned and how long is it expected to last?
■Packaging: How will the sensor be integrated into the application? What does the sensor’s housing need to withstand and how does the sensor need to be constructed (size, shape, weight)?
■Environment: What’s the sensor going to be exposed to while in use? Air? Fluid? Chemicals?
Custom medical temperature sensors for top-tier patient care Though the world of medicine and treatment is ever evolving, the individuality of patients and the need for extremely accurate monitoring remains constant. With an increasing focus on
personalised medical treatments driving the need for more-tailored monitoring solutions, high-performance sensor solutions are an absolute must – especially in critical care.
By incorporating custom temperature sensors into medical equipment, healthcare providers can enhance their ability to deliver personalised and precise treatments, ultimately improving patient safety and well-being. ●
