Description

Non-contact body temperature measurement system

The present invention relates to a non-contact body temperature measurement system, and more particularly, to a system capable of measuring a patient's body temperature more accurately in a non-contact manner in a hospital, but continuously for a predetermined time.

In general, medical beds are used in hospitals, silver towns, etc. for patients who require long-term treatment or have many restrictions on their activities. Such a medical bed is provided with various convenience devices for adjusting the posture of the patient to lie down or sit. In addition, the medical bed is provided with various devices for assisting the examination of the patient's condition, such as the patient's weight, pulse, blood pressure check.

On the other hand, in order to measure the body temperature of a patient lying on a medical bed, a conventional contact type thermometer is used. In the case of such a contact thermometer, since the patch is directly attached to the patient's skin, there is a problem in that it is inconvenient to use. To improve this, a patient's body temperature may be measured in a non-contact manner using an infrared thermometer or the like. However, in the case of the non-contact type, it is still inconvenient to use because a person has to directly measure it, and there is a problem in that the accuracy is lower than that of the contact type.

In particular, the controller 150 analyzes the image data captured by the camera 130 and determines a specific part of the patient P from the image to control the robot arm 120 , and the thermometer 110 controls the specific part. It is possible to control to measure the body temperature of the patient (P) in a range of a certain distance spaced toward the. For example, a specific portion of the patient P, where the thermometer 110 measures body temperature in a non-contact manner, may be an exposed skin portion of the patient P, such as a forehead or an ear. However, the controller 110 may correct body temperature data measured by the thermometer 110 .

Hereinafter, an operation for measuring body temperature, in particular an operation for correcting body temperature data, according to an embodiment of the present invention controlled by the controller 150 will be described.

3 is a flowchart of a body temperature measuring operation performed in the non-contact body temperature measuring system 100 according to an embodiment of the present invention.

The operation of measuring body temperature according to an embodiment of the present invention may include steps S100 to S400 as shown in FIG. 3 .

In S100 , the controller 150 controls the robot arm 120 so that the thermometer 110 is spaced apart from the bed B or the heating part H of a predetermined temperature installed in the vicinity thereof by a predetermined distance range. In this case, it may be preferable that the corresponding separation distance range is the same as the distance at which the corresponding thermometer 110 is spaced apart from the patient P for the temperature measurement of the patient P in S300 and S400.

It may be preferable that the heating part H constantly heats up to a temperature in the body temperature range of a person. This is to reduce errors in the calibration process for body temperature data, which will be described later. For example, the heat generating unit H may generate heat at a constant temperature in a temperature range of 35 °C to 40 °C. Hereinafter, the temperature maintained constant in the heating part H is referred to as a “heating temperature”.

Thereafter, in S200 , the controller 150 controls the thermometer 110 to measure the temperature of the heat generating unit H. At this time, the measured data (referred to as “exothermic temperature data”) is transmitted to the controller 150 .

In addition, the heating part (H) may be preferably provided around the head position when the patient (P) is lying on the bed (B) for ease of measurement. In particular, in order to prepare for the failure, a plurality of heat generating units H may be provided.

Thereafter, in S300 , the controller 150 controls the robot arm 120 so that the thermometer 110 is spaced apart by a predetermined distance toward a specific part of the patient P.

Thereafter, in S400 , the controller 150 controls the thermometer 110 to measure the body temperature of the patient P toward the specific part. At this time, the measured data (referred to as “body temperature data”) is transmitted to the controller 150 . Thereafter, the controller 150 corrects the measured body temperature data of the patient P based on the measured fever temperature data of the heat generating unit H.

For example, when the heating temperature of the heating part H is 37°C and the measured heating temperature data is 38°C, a difference value of 1°C occurs. Thereafter, the controller 150 may correct the body temperature data by reflecting the corresponding difference value in the measured body temperature data. For example, the body temperature data may be corrected by adding or subtracting a difference value to the body temperature data. Alternatively, the controller 150 may correct the body temperature data by reflecting the ratio of the fever temperature to the fever temperature data in the body temperature data. For example, the body temperature data may be corrected by multiplying the corresponding ratio by the body temperature data. Hereinafter, the corrected body temperature data is referred to as “correction data”.

Thereafter, the control unit 150 may output the correction data to the output unit or transmit it to the communication unit. In particular, when the correction data falls within a predetermined abnormal range (eg, less than 36 ℃, more than 38 ℃, etc.), the controller 150 may output a warning notification for this to the output unit or transmit it to the communication unit.

By continuously repeating steps S100 to S400 , the controller 150 may continuously measure the body temperature of the patient P. However, during the iterative process, S100 and S200 may be omitted. That is, the processes S100 to S400 are repeated, but S100 and S200 may be performed only in a specific period.

The present invention configured as described above measures the body temperature of the patient P lying on the medical bed B in a non-contact manner, and can measure the body temperature more accurately while increasing the ease of use, and in particular, continuously measures the body temperature for a certain period of time There are advantages to being able to
