The thermoelectric module 240 uses a Peltier effect in which heat dissipation is generated at one side and endothermic action is generated at the other side when the power is supplied by bonding different metals together. The water filled in the zigzag flow path of the cooling / heating unit 200 is cooled or heated.

The cooling / heating unit 200 is preferably made of a material having good thermal conductivity such as copper and aluminum.

On the other hand, when it is necessary to discharge the water filled in the zigzag flow path of the cooling / heating unit 200, it can be discharged after separating the circulation line from the supply hole (230h1) or discharge hole (230h2), Of course, a separate drain hole (not shown) may be provided and discharged therethrough.

The circulation drive unit 300 includes a circulation line 310 and a circulation pump 320, and the circulation line 310 forms a flow path through which water can be circulated so that the water of the cooling / heating unit 200 is circulated. The circulation pump 320 is a portion that provides power for circulating water so that the water in the cooling / heating unit 200 can be circulated along the circulation line 310.

The cold pad part 400 is a part for raising or lowering the body temperature as a part of the circulation line 310 is built in contact with a part of the body, for example, inside the soft cloth material such as a towel. The circulation line 310 may be embedded, or in addition, the circulation line 310 may be embedded in a flexible synthetic resin material that is elastically deformable and has good heat transfer. Of course, variations are possible.

In addition, the cold pad 400 may be modified in various sizes and shapes according to the characteristics of various human body parts that require body temperature control.

On the other hand, in order to increase the heat exchange efficiency between the cold pad portion 400 and the body, a fruit object (not shown) surrounding the circulation line 310 built in the cold pad portion 400 is the inside of the cold pad portion 400 It may be provided in.

The control unit 500 is located in a part of the body (for example, the armpit) based on the body temperature sensed by the body temperature sensor (S1) for sensing the body temperature and the temperature setting value set by the user, the cooling / heating unit Control the operation of the 200 and the circulation pump 320 individually to increase or decrease the body temperature.

As shown in FIG. 4, when the user sets a temperature lowering mode to apply to a patient having a high body temperature, the controller 500 controls the cooling / heating unit 200 when the body temperature is higher than the temperature setting value. Turn on the cooling operation and the operation of the circulation pump 320, and when the body temperature is lower than the body temperature set value, the cooling operation of the cooling / heating unit 200 and the operation of the circulation pump 320 are turned off. To lower.

For example, a patient having a body temperature of 39 ° C. needs to take measures to lower the body temperature. Accordingly, if the user sets the temperature lowering mode, but sets the temperature setting value to 36.5 ° C., the patient's body temperature is higher than 36.5 ° C. In this case, the cooling operation of the cooling / heating unit 200 and the operation of the circulation pump 320 are turned on to lower the temperature of the patient, and the cooling / heating unit (if the body temperature of the patient becomes lower than 36.5 ° C. ( The cooling operation of the 200 and the operation of the circulation pump 320 are turned off so that the body temperature of the patient no longer falls.

Although the temperature setting value is illustrated as a single value, it may be configured to be set in the form of a temperature range. In this case, the body temperature sensor S1 determines whether it is out of the temperature range based on the upper limit value or the lower limit value of the set body temperature set value.

On the other hand, as shown in Figure 1, in order to detect the flow rate of the water circulating through the circulation line 310 is provided with a flow meter (S3), in particular, the flow meter (S3) is the circulation of the cold pad portion 400 Finished is provided in the circulation line 310 corresponding to the discharged portion.

Therefore, the control unit 500 determines that the flow rate is not detected in the flow meter S3 while the operation of the circulation pump 320 is turned on during the temperature lowering mode operation by the user as a failure, and generates a failure alarm. Generated, and the operations of the cooling / heating unit 200 and the circulation pump 320 are turned off to prevent damage due to overcooling.

On the other hand, as shown in Figure 5, when the user sets the temperature rise mode to apply to a patient with a low body temperature, the control unit 500, the cooling / heating unit when the body temperature is lower than the temperature set value The heating operation of the 200 and the operation of the circulation pump 320 are turned on, and when the body temperature is higher than the body temperature setting value, the cooling operation of the cooling / heating unit 200 and the operation of the circulation pump 320 are turned off. Increase your body temperature.

For example, a patient having a body temperature of 35 ° C. needs to take measures to raise and lower the body temperature. Accordingly, if the user sets the temperature raising mode, but sets the temperature setting value to 36.5 ° C., the patient's temperature is lower than 36.5 ° C. In this case, the heating operation of the cooling / heating unit 200 and the operation of the circulation pump 320 are turned on to raise the temperature of the patient, and the cooling / heating unit 200 when the temperature of the patient becomes higher than 36.5 ° C. The heating operation and the operation of the circulation pump 320 is turned off so that the body temperature of the patient does not rise any more.

In addition, the control unit 500 determines that the flow rate is not detected in the flow meter S3 while the operation of the circulation pump 320 is turned on during a temperature rising mode operation by a user as a failure alarm. And turn off the operations of the cooling / heating unit 200 and the circulation pump 320 to prevent damage due to overheating.

On the other hand, the change in the body temperature in the form of a graph can be grasped as the state of the body temperature changing during the control operation of the controller as described above is transmitted to the printer (600 in FIG. 1) and output.

The cooling / heating unit 200, the water tank 100, the control unit 500, etc. may be assembled in a casing made of a hard synthetic resin material, for example, in consideration of ease of use and design. In particular, the cold pad device of the present embodiment can be implemented in a compact structure as a whole by using the thermoelectric module 240 as a heat source (or a cooling source).

Second Embodiment

In the temperature control cold pad device according to the second embodiment of the present invention, the water temperature sensor S2 is added to the configuration of the temperature control cold pad device of the first embodiment, and the description of the same configuration as in the first embodiment will be omitted. The control operation of the added water temperature sensor S2 and the control unit 500 using the same will be described.

The water temperature sensor S2 is installed in the circulation line 310 to sense the temperature of the water circulated in the cold pad 400.

As shown in FIG. 6, when the user sets a temperature lowering mode to apply to a patient having a high body temperature, the controller 500 determines that the body temperature is higher than the temperature setting value and the water temperature is higher than the set water temperature setting value. When the cooling operation of the cooling / heating unit 200 and the operation of the circulation pump 320 is turned on, the cooling / heating unit when the body temperature is higher than the body temperature set value and the water temperature is lower than the set water temperature set value The cooling operation of the 200 is turned off and the operation of the circulation pump 320 is turned on. When the body temperature is lower than the body temperature setting value, the cooling operation of the cooling / heating unit 200 and the circulation pump 320 are performed. Turn off the operation to lower the body temperature.

For example, a patient whose temperature is 39 ° C. needs to take measures to lower the body temperature. Accordingly, the user sets the temperature lowering mode, but sets the temperature setting value to 36.5 ° C. and the water temperature setting value to 35 ° C. When the body temperature of the patient is higher than 36.5 ° C., the controller 500 compares the water temperature and the water temperature set value of the circulating water.

As described above, as the temperature of the circulating water is maintained at 35 ° C., the temperature difference between the body temperature and the water temperature is increased as the temperature of the circulating water becomes too low when the temperature decreases, thereby preventing a body shock that may occur.

The water temperature setting value may be configured to be automatically set according to the temperature setting value without the user setting manually. For example, when the user sets the body temperature setpoint to 36.5 ° C, the control unit may be operated to automatically set the water temperature setpoint to a temperature lower than 2 to 3 ° C.

On the other hand, when the patient's body temperature is lower than 36.5 ℃ to turn off the cooling operation of the cooling / heating unit 200 and the operation of the circulation pump 320 so that the body temperature of the patient no longer falls.

As shown in FIG. 7, the control unit 500 includes a heating operation and a circulation pump of the cooling / heating unit 200 when the body temperature is lower than the body temperature setting value and the water temperature is lower than the set water temperature setting value. The operation of the control unit 320 is turned on and the heating operation of the cooling / heating unit 200 is turned off and the operation of the circulation pump 320 when the body temperature is lower than the body temperature setting value and the water temperature is higher than the set water temperature setting value. When the body temperature is higher than the body temperature set value, the heating operation of the cooling / heating unit 200 and the operation of the circulation pump 320 to turn off the body temperature.

For example, a patient having a body temperature of 35 ° C. needs to take measures to raise and lower the body temperature. Accordingly, the user sets the temperature raising mode, but sets the temperature setting value to 36.5 ° C. and the water temperature setting value to 38 ° C. When the body temperature of the patient is lower than 36.5 ° C., the controller 500 compares the water temperature and the water temperature set value of the circulating water.

If it is determined that the water temperature of the circulating water is lower than 38 ° C. of the water temperature setting value, the heating operation of the cooling / heating unit 200 is turned on and the operation of the circulation pump 320 is turned on to raise the temperature of the patient, and the temperature of the patient. When it is determined that the water temperature of the circulating water is higher than 38 ° C. of the water temperature setting value, the heating operation of the cooling / heating unit 200 is turned off and the operation of the circulation pump 320 is turned on to lower the body temperature of the patient.

As described above, as the temperature of the circulating water is maintained at 38 ° C., the temperature difference between the body temperature and the water temperature increases as the temperature of the circulating water becomes too high to prevent body abnormalities or burns that may occur. .

Like the cooling mode, the water temperature setting value may be configured to be automatically set according to the body temperature setting value without a user setting manually.

On the other hand, when the patient's body temperature is higher than 36.5 ℃ to turn off the heating operation of the cooling / heating unit 200 and the operation of the circulation pump 320 so that the body temperature of the patient no longer rises.

Although the temperature setting value is illustrated as a single value, it may be configured to be set in the form of a temperature range. In this case, the water temperature sensor S2 determines whether it is out of the temperature range based on the upper limit value or the lower limit value of the set water temperature set value.

Although the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many different and obvious modifications are possible without departing from the scope of the invention from this description. Therefore, the scope of the invention should be construed by the claims described to include many such variations.
