Description

Apparatus and method for preventing low-temperature burns on heating mats {APPARATUS AND METHOD FOR PREVENTING LOW TEMPERATURE BURNS OF WARM MATT}

One embodiment of the present invention relates to a heating mat low temperature burn prevention apparatus and method.

In general, the heating mat is to provide a warming effect to users in winter by dissipating heat according to the supply of power, and is manufactured in various forms such as cushions, lap blankets, and rugs.

A general structure of the heating mat includes a heating part formed of a heating wire and a cover formed to surround the heating part. Such a heating mat has a feature of providing heat to the user by dissipating heat from the heating unit according to the supply of power.

However, conventional heating mats or heating mats uniformly supply heat until a set temperature is reached. In the case of the general public, if the skin is stimulated by the continued heat while lying on a heating mat, it is possible to prevent the continued thermal stimulation to the same area by moving the body. However, when a severely immobilized patient uses a heating mat for blood circulation to maintain body temperature and prevent pressure sores, even if the thermal stimulation continues, he/she cannot move his body, and thus suffers a low-temperature burn due to the continuous thermal stimulation. However, if a heating mat is not used, there is no means to maintain body temperature, and in particular, pressure sores occur because blood circulation is not performed properly. Therefore, it is necessary to be able to prevent low-temperature burns even when a heating mat is used.

Although the controller 300 may control the temperature of the heating unit 200 by supplying appropriate power, a plurality of temperature sensors 230 may be installed in the heating wire 220 to more reliably control the temperature. The temperature sensor 230 senses the temperature of the heating wire 220 , and when the temperature of the heating wire 220 is higher than the set temperature, the temperature sensor 230 transmits the fact to the controller 300 . Power can be turned off.

In this way, it is possible to prevent low-temperature burns that occur when a seriously ill patient who can hardly move using a general heating mat. However, since it is difficult to completely prevent low-temperature burns from this point alone, it is possible to prevent low-temperature burns from occurring even in the case of severe patients who cannot move through the operation of the thermal contact part described below.

4 is a diagram illustrating an operation of the thermal contact unit 100 according to an embodiment of the present invention. In FIG. 4 , the heating part 200 is omitted from the drawing in order to clarify the operation of the heating contact part 100 .

Referring to FIG. 4 , the plurality of air pockets 120 included in the thermal contact part 100 do not all operate together, but are divided into two or more sets so that the air in the air pockets 120 enters and exits for each set. there is. For example, in the case of the air pockets 120a and 120b divided into two sets as in FIG. 4 , air is first injected into only the first air pocket set 120a and air is injected into the second air pocket set 120b. may not be (see FIG. 4(a)). In addition, in a state in which air is injected into the first set of air pockets 120a, air is also injected into the second set of air pockets 120b and air may be injected to both sides (refer to FIG. 4(b) ). . And, the first air pocket set (120a), the air is exhausted, the second air pocket set (120b) can be maintained in a state in which air is injected (refer to Fig. 4 (c)). Then, air is again injected into the first air pocket set 120a to obtain a state as shown in FIG. 4(b), and thereafter, the state of FIG. 4(a) may be repeated again.

In this way, as the injection and discharge of air are alternately repeated with respect to the plurality of air pockets, the portion in which the heating unit (not shown in FIG. 4 ) positioned under the lying user contacts the user's body can be continuously changed. . That is, the heating part does not continuously contact with one part, but the heating part contacts and then falls off with respect to one part may be repeated. For this reason, it is possible to prevent low-temperature burns occurring when the heating mat is in contact for a long time. In particular, in the case of a severe patient who cannot move, when a heating mat is used, low-temperature burns inevitably occur unless others move their body. Accordingly, it is possible to prevent the heating unit from being in contact for a long time.

In FIG. 4 , the plurality of air pockets 120 are shown as being divided into two sets, a first air pocket set 120a and a second air pocket set 120b, but the present invention is not limited thereto. 3 sets, 4 sets It can be divided into two or more sets. Even in this case, as described above, the injection and discharge of air for each air pocket set may be alternately performed.

5 is a view showing the shape of the thermal contact portion, particularly the air pockets 120c and 120d according to another embodiment of the present invention.

Referring to FIG. 5 , as described above, not all air pockets 120 have a cylindrical shape, but a truncated cone shape with different sizes a1 and a2 on both sides for each air pocket 120c and 120d. . In addition, the adjacent air pockets 120c and 120d have an inverted shape, so that when a plurality of air pockets are combined, the shape of the plurality of air pockets may correspond to the shape of the heating unit. That is, when the upper width of one air pocket 120c is a1 and the lower width is a2 based on the paper of FIG. 5 , the upper width of another adjacent air pocket 120d is a2, and the lower width is a2. may be a1.

6 is a diagram illustrating an operation by a thermal contact unit including the air pockets 120c and 120d of FIG. 5 . In FIG. 6 , the heating part 200 is omitted from the drawing in order to clarify the operation of the heating contact part.

Referring to FIG. 6 , even in the case of the air pockets 120c and 120d of the thermal contact part according to the present embodiment, two or more sets may be formed and operated alternately as in the previous embodiment. For example, in the case of the air pockets 120c and 120d divided into two sets as shown in FIG. 6 , first air is injected into only the first air pocket set 120c and air is injected into the second air pocket set 120d. It may not be possible (see FIG. 6(a)). In addition, in a state in which air is injected into the first set of air pockets 120c, air is also injected into the second set of air pockets 120d, and air may be injected to both sides (refer to FIG. 6(b) ). . In addition, the first air pocket set (120c), the air is exhausted, the second air pocket set (120d) can be maintained in a state in which the air is injected (refer to Fig. 6 (c)). Then, air is again injected into the first air pocket set 120c to obtain a state as shown in FIG. 6(b), and thereafter, the state of FIG. 6(a) may be repeated again.

In this way, by alternately injecting and discharging air with respect to the plurality of air pockets, as in the previous embodiment, a portion where the heating unit (omitted in FIG. 6 ) positioned under the lying user comes into contact with the user's body. may be continuously changed. In addition, by alternately inflating the air pockets of different sizes on both sides, the user's body lying down can perform a left-to-right motion. For this reason, it is possible to further prevent low-temperature burns occurring when the heating mat is in contact for a long time.

7 is a flowchart illustrating temperature control of the heating unit 200 according to another embodiment of the present invention.

Referring to FIG. 7 , in order to more reliably prevent low-temperature burns, the control circuit in the control unit 300 may control the temperature in the following manner.

When the user sets the desired temperature (eg, 40 ℃) (S1), the set temperature (eg, 40 ℃) is maintained for a predetermined time n1 minutes (eg, 20 minutes), n1 When the min is reached, it can be held for n2 min (eg 20 min) at a temperature lower than the set temperature (eg 35°C). And, when the state of the lower temperature than the set temperature elapses by n2 minutes, it rises again to the set temperature and can be maintained for n1 minutes. And, when n1 minutes have elapsed again, it is possible to maintain a temperature lower than the set temperature for n2 minutes again.

In this way, by preventing the temperature of the heating unit 200 from maintaining the set temperature for a predetermined time or longer in the control unit 300 , it is possible to prevent low-temperature burns together with the various methods described above.
