Product Usage Main Purpose: The thermometer is mainly used for measuring human body temperature. Measurement Range: 35°C to 42°C. Thermometer Reading Tolerance: ±0.1°C to ±0.15°C. Specification: Built-in thermometer Packaging: 12 per box Glass Thermometer Usage Method: Hold the upper end of the thermometer and let the mercury column fall below 35°C. 1. Oral Method: After disinfecting with 75% alcohol, place the oral thermometer under the patient's tongue, close the mouth for 5 minutes, then remove it. Point the mercury ball section with the triangular prism, aim it slightly forward and backward, and the mercury column will be clearly visible for reading. This method is only used for patients who are unconscious and infants. When measuring, do not speak to prevent biting the thermometer or dislodging it. 2. Axillary Method: Dry the armpit sweat, disinfect the thermometer with 75% alcohol, then place it under the armpit for 10 minutes. After measuring, clean the thermometer with alcohol and store it in a dry place.After alcohol disinfection, place the mercury end of the thermometer in the armpit, and it can be removed after 5 minutes to read the temperature. When measuring, hold the armpit tightly and do not move around to prevent the thermometer from slipping out or falling, causing damage or poor measurement. The body's temperature is relatively constant, and the temperature fluctuates slightly within 24 hours, generally no more than 1 degree. In a physiological state, the body temperature is slightly lower in the morning and slightly higher in the afternoon. The temperature is slightly higher after exercise, eating, before or during pregnancy in women, and the temperature is lower in the elderly. If the temperature is higher than normal, it is called fever. Temperature of 37.538 degrees is low fever, 3839 degrees is moderate fever, 3940 degrees is high fever, and above 40 degrees is hyperpyrexia. The relative constancy of body temperature is an important condition for maintaining the normal life activities of the body. If the body temperature is higher than 41 degrees or lower than 25 degrees, it will seriously affect the function of various systems (especially the nervous system), and even endanger life. The production of heat and heat dissipation of the body are regulated by the nervous center, and many diseases can make the normal regulation of body temperature function occur disorders and make the body temperature change. In clinical examination of patients' body temperature, observing the changes of body temperature has important significance for the diagnosis of diseases or the prognosis of some diseases. 1) About the problem of product return and exchange? 1) If the product is defective or has quality problems within the warranty period, the customer can apply for a return or exchange.
