Temperature difference type urine collection bag urine level alarm

Abstract

The utility model discloses a temperature difference type urine level alarm for a urine collection bag, and solves the problem that the rest of nursing personnel is affected when the nursing personnel manually monitor the urine level of the urine collection bag at present. The two temperature sensors are installed between the electric heating belt and the urine collecting bag, the temperature of the electric heating belt is higher than that of the urine collecting bag, heat of the electric heating belt is transmitted to the urine collecting bag through the temperature sensors, when the temperature sensors are below the urine level, the heat is directly transmitted to urine through the urine collecting bag, and when the temperature sensors are above the urine level, the heat is directly transmitted to the urine through the urine collecting bag. Heat is transmitted to air through the urine collecting bag, and the heat conductivity coefficient of the air is smaller than that of urine, so that the temperature of the temperature sensor above the urine level is higher than that of the temperature sensor below the urine level. When the urine reaches the position between the two temperature sensors, the temperature difference between the two temperature sensors exceeds a certain set value, and the alarm circuit gives out an alarm sound.

Description

Technical Field

[0001] The utility model relates to a temperature difference type urine collecting bag urine level alarm, in particular to a medical urine infusion and urine collecting bag urine level alarm device. Background Art

[0002] When the patient is unconsciously urinating in bed, a urine collection bag is needed to store the patient's urine. When the urine reaches a certain height, the nurse is required to drain the urine. The nurse has to monitor the urine level in the urine collection bag, which consumes the nurse's energy and affects the nurse's rest, especially at night. After using the temperature difference urine collection bag urine level alarm, when the urine level reaches the set position, the alarm will sound an alarm to remind the nurse to drain the urine in the urine collection bag.
