Application And Advantages Of Body Temperature Probe

Monitoring physiological parameters of patients is a critical task in clinical diagnosis and treatment. It allows doctors to understand the instantaneous physiological changes of patients, so as to timely detect and deal with the problems of patients and ensure their life and health. The monitor is a medical instrument used to monitor the vital signs of patients and reflect the instantaneous physiological changes of patients in time, which can help doctors accurately find problems and deal with problems and ensure the life safety of patients. Medical temperature probes allow for more accurate, safer, and more comfortable continuous patient temperature management, and this temperature probe plays an increasingly important role in the prognosis period during anesthesia and after surgery.

In order to cope with the different temperature measurement needs of patients, the medical disposable body temperature probe can be simply divided into: body cavity body temperature probe, body surface body temperature probe, ear canal body temperature probe, temperature measurement urinary catheter and esophageal body temperature probe. The mean oral, axillary, and rectal temperatures obtained by real-time monitoring of the patient 's body temperature with a body temperature probe were not significantly different from those measured by a mercury thermometer, and were more convenient and safe.

Working principle of body temperature probe

The probe for body temperature measurement contains a high-precision thermistor whose impedance varies with the external temperature. The instrument converts the impedance change of the thermistor into an electrical signal and calculates the temperature value.

Placement of body temperature probe

The probe conducts the temperature by the heat transfer surface and is used as a thermometer. If the probe is not properly connected to the body surface, or the patient 's movement causes the probe to become loose, it will result in incorrect temperature values. To avoid this, it is recommended that two tapes be used to securely attach the temperature probe to the patient 's axillary fossa, one tape will be attached to the skin and the other to secure the lead of the probe so as not to cause the probe to fall off when pulled.

Cleaning and Maintenance of Body Temperature Probe

In daily maintenance, the cable surface dirt of body temperature probe can be cleaned after soaking the sponge with soapy water or other appropriate cleaning agent, then wiped dry, and the probe can be disinfected with absolute alcohol. Do not immerse the probe cable in water, let alone scrub with any abrasives. The temperature resistance of body temperature probe shall not exceed 60℃, and it is strictly prohibited to use the way of high temperature and high pressure for disinfection. Probes and cables are stored at temperatures between -20℃ and + 60℃ and may be suspended or laid flat when not in use to prevent damage and do not bend or twist cables strongly.

Disposable body temperature probe for accurate measurement:

1. Good insulation protection prevents the risk of electric shock and is safer; prevent liquid from flowing into the connection and ensure correct reading;

2. Anti-interference design of temperature probe, the probe end distributes the radiation reflection paste, and while fixing the paste position, it can also effectively isolate the ambient temperature and radiated light interference and ensure that the body temperature monitoring data are more accurate;

3. the patch does not contain latex, and viscous foam evaluated by biocompatibility can fix the temperature measurement position, wear comfortably and is not irritating to the skin;

4. It can be used in combination with neonatal incubator to meet the requirements of high neonatal safety and hygiene index.

At present, most ICU wards or departments requiring real-time monitoring of patient body temperature in many large hospitals use disposable medical temperature probes as an important tool for patient body temperature management.
