Description

Foot heating device

Technical Field

The present application relates to the field of heating, and more particularly to a foot heating device.

Background

The human body needs to be kept at a certain temperature in daily life to ensure that each function of the human body can normally operate. This is usually achieved in the life of people by various clothing worn by people, and especially when the surrounding environment is cold, people can increase the thickness of the clothing covered by the surface of the human body by adding clothing, thereby preventing heat exchange between the surface of the skin of the human body and the external environment as much as possible, so as to keep the temperature of the human body at a temperature suitable for the human body. However, since it is generally difficult to achieve the effect of the clothing with the trunk of the human body by increasing the thickness or number of the wraps, the foot of the human body tends to be the portion of the human body that dissipates the heat most rapidly, and thus, a device capable of heating the foot is required.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The body temperature monitoring of the surgical patient should be of dynamic continuity, covering the entire perioperative period, including preoperative, intra-operative and post-operative recovery periods. The body temperature monitoring is recommended to be started before operation and used as a basic body temperature value of a patient, so that a reference is provided for implementing pre-heat preservation; the postoperative body temperature monitoring is also very important, so that the effect of the intraoperative body temperature protection measures can be evaluated, and reference can be provided for subsequent treatment.

The body temperature is reduced, so that patients are easy to feel uncomfortable after operations, such as chills, limb coolness, tingling and the like, and restlessness in a recovery period is caused, more importantly, serious harm is caused to the circulatory system, blood coagulation, immune mechanism and other aspects of organisms, the incidence rate of complications related to anesthesia is high, the hospitalization time is prolonged, and the economic burden of the patients is increased.

The human body needs to be kept at a certain temperature in daily life to ensure that each function of the human body can normally operate. This is usually achieved in the life of people by various clothing worn by people, and especially when the surrounding environment is cold, people can increase the thickness of the clothing covered by the surface of the human body by adding clothing, thereby preventing heat exchange between the surface of the skin of the human body and the external environment as much as possible, so as to keep the temperature of the human body at a temperature suitable for the human body. However, since the foot of the human body is often difficult to achieve the effect of increasing the thickness or number of the wrapping and the trunk of the human body by increasing the clothing, the foot of the human body is often the part of the human body where the heat loss is the fastest, and especially when the user is in a low temperature environment, the position of the foot is also often the lowest temperature position in the environment, so that the skin of the foot and the lower leg part exchanges more heat with the external environment, that is, the human body loses more heat from the foot and the lower leg part more easily.

In addition, since the feet of the human body are positioned at the lowest position of the human body, the reflux distance of blood to the heart in the blood vessels under the skin is also the farthest, so the blood circulation speed of the feet and the lower legs is also the slowest, and in the case where the outside environment temperature is low, the speed of blood circulation becomes slower due to the reduction of the skin temperature when the temperature of the feet of the human body is reduced due to the heat exchange of the skin with the outside environment, which makes the user feel the feet more cold.

For this reason, foot heating devices have been proposed in the prior art which are fitted over the feet of a person in the form of a sleeve, so that the skin of the foot is supplemented with heat by such a heating sleeve which surrounds the foot of the person. However, since the prior art foot covers need to be adapted to the wear of most users, they need to be made with a larger inner diameter or space to facilitate the placement of the feet therein by users with larger foot sizes. However, in such cases, most users with ordinary foot sizes often have their feet not fully filled with the foot cover when placing their feet in the foot cover, so that there is a large spacing between the skin of the foot and the heating surface inside the foot cover. When the heating foot cover is heated, the heating surface can only exchange heat with the air near the heating surface to raise the temperature of the air near the heating surface of the foot cover, and the air heated by the heating surface of the foot cover can also continue to exchange heat with the adjacent air to heat the adjacent air, and in a similar manner, the air around the skin surface of the foot is also heated and further exchanges heat with the skin surface of the foot.

However, in the above process, since the foot cover does not fit the shape of the foot of the human body well, and thus, there is a large space between the heating surface of the foot cover and the skin surface of the foot of the human body during use by the user, and when the above heat exchange is performed in such a large space, a part of heat is lost each time of the heat exchange, and thus, when the air near the skin surface of the foot is heat-exchanged with the air adjacent thereto, the heat initially provided by the heating surface of the foot cover has been consumed more in the course of the heat exchange many times, and thus, the heating effect of the air on the skin surface of the foot is very limited, and even very small, so that the temperature of the skin surface eventually transferred to the foot is lowered more, and the actual heating effect of the foot of the user is very limited, although the temperature of the heating surface of the foot cover is high.

The inventor has made a great deal of research work on the original equipment for warming feet. Firstly, placing experimenters in a water bath basin with water temperature of 40 ℃, selecting 20 persons, repeating each person for 3 times for 1 hour, and finally counting the temperature rise of the core body temperature, wherein the average core body temperature of each person has the temperature rise of more than 0.5 ℃. The 20-person foot warming apparatus was also set at 40 ℃, and in the same manner, the core body temperature of the experimenter hardly increased at all. In fact, the analysis is relevant to the fact that the normal experimenter has a certain regulatory function.

The inventor has carried out a large amount of analysis on data, found that the effect of heating is greatly related to the effective contact surface of the heating part and the patient, and although the temperature of the heating surface is relatively high, the heat cannot be sufficiently transferred to the human body under the condition that the heating part is not sufficiently contacted with the human body, so that how to design the foot heating device to be capable of being sufficiently contacted with the human body is very important, and meanwhile, the foot heating device can still be sufficiently contacted under the condition that the application range is relatively large for different crowds, so that the foot heating device is very important.

For this reason, the embodiment of the present application proposes a foot heating device, as shown in fig. 1, fig. 1 is a schematic view showing the structure of the foot heating device according to the embodiment of the present application. In the foot heating device shown in fig. 1, a vertical surface heating portion 11 and a bottom surface heating portion 12 forming an angle with each other may be included. For example, the extension plane of the elevation heating part 11 and the extension plane of the bottom surface heating part 12 may intersect each other and thus form a certain angle, and in particular, in the present embodiment, the elevation heating part 11 and the bottom surface heating part 12 may have planar or nearly planar shapes, respectively, and may be made of flexible materials so as to conform to the shapes of the legs and feet of a human body when worn on the lower legs and feet of the human body. And the elevation heating part 11 and the bottom surface heating part 12 may have been formed in an L-like shape before being worn on the foot of the human body, i.e., the bottom surface heating part 12 for heating the foot may be on a horizontal plane, and the elevation heating part 11 may be on an inclined plane with respect to the horizontal plane, for example, at an obtuse angle, so as to correspond to an angle between the foot and the lower leg of the human body, for convenience of wearing by the user.

Further, the sides of the elevation heating portion 11 and the bottom surface heating portion 12 adjacent to each other, for example, adjacent sides in the respective extending plane directions, for example, a side 121 of the bottom surface heating portion 12 located on one side of the elevation heating portion 11 in the horizontal plane and a side 111 of the elevation heating portion 11 located on the lower side in the inclined direction, may be joined to each other, so that the joint region 13 having the first width may be formed with the inwardly extending portions 112 and 122 of the elevation heating portion 11 and the bottom surface heating portion 12 located on the corresponding sides 111 and 121 thereof, respectively, based on the sides 111 and 121 thus joined to each other.

In other words, in the embodiment of the present application, the elevation heating portion 11 and the bottom heating portion 12 whose extension planes intersect each other at an angle, for example, an obtuse angle, may be joined at one side and extended to the other side by a certain width based on the joined sides, respectively, in addition to the respective sides as the joining region 13. In this way, the joint region 13 can be used as a transition region from the horizontal plane in which the floor heating 12 is located to the inclined plane in which the elevation heating is located. This transition region may on the one hand serve as a region corresponding to the heel of a person's foot when the foot heating device according to embodiments of the present application is worn on the person's foot.

For example, the feet of a human body are generally in a horizontal plane (when the human body stands), while the lower legs are generally at an angle to the feet, and the heels become a turning part from the horizontal plane in which the feet are located to an inclined plane in which the lower legs are located, even an upright plane, so the foot heating device of the embodiment of the present application can avoid the direct transition from the bottom surface heating part 12 to the elevation heating part 11 by forming the engagement region with a certain width, but the engagement region 13 with a certain width is made to have a first curvature in the width direction, that is, a certain curvature, so that the curvature of the heel part of the human body can be fitted by means of the curvature when being worn on the foot of the human body, thereby realizing the fitting of the heel part.

The elevation heating portion 11 may include a first heating unit 113 and a first power unit 114. The first heating assembly 113 may be located at an intermediate portion of the elevation heating 11 except for a portion located in the joint region 13. For example, the first heating member 113 may have a strip shape and may be, for example, a plurality of strip-shaped heating members extending along the length direction of the elevation heating part 11, that is, along the inclined direction of the elevation heating part 11, and the plurality of heating members may be spaced apart from each other by a predetermined distance in a direction perpendicular to the inclined direction. Further, the first heating element 113 may also be constituted by a plurality of strip-shaped heating elements extending in the plane of the elevation heating portion 11 in a direction perpendicular to the inclination direction of the elevation heating portion 11, and these heating elements may be spaced apart from each other with a predetermined interval in the inclination direction of the elevation heating portion 11. Further, in the embodiment of the present application, the first heating element 113 may further include a plurality of U-shaped heating element groups formed of strip heating elements extending in the oblique direction of the elevation heating part 11 and strip heating elements extending in a direction perpendicular to the oblique direction, or a plurality of lattice-shaped heating element groups formed of strip heating elements extending in the oblique direction of the elevation heating part 11 and strip heating elements extending in a direction perpendicular to the oblique direction. In particular, in the present embodiment, the first heating elements 113 may be distributed only in other portions of the elevation heating 11 than the portions located within the joining region 13. For example, as shown in fig. 1, the first heating assemblies 113 may be distributed only in the middle region, and may be spaced apart from the respective side edges by a predetermined distance. This can prevent the first power assembly 114 extending in the side portion from being damaged by the temperature rise also at the time of the heating operation of the first heating assembly 113.

The first power assembly 114 may be disposed along the perimeter of the facade heating 11, for example, in the outer side of the facade heating 11 as described above. For example, a protective sheath made of an insulating material may be provided on an outer edge of the elevation heating 11 so that the first power assembly 114 may extend therein, and one or more openings may be provided therein, which may be directed toward the first heating assembly 113 provided at a middle portion of the elevation heating 11. For example, at least one opening to the first heating assembly may be provided in the protective case of each side, or at least one opening to the first heating assembly 113 may be provided in the protective case of at least one side, so that the power assembly 114 may be connected to the first heating assembly 113 through the opening, and the first heating assembly 113 may be supplied with power required for heating and a control signal from the control circuit 14.

Power modules may be provided on both sides in the longitudinal direction of the joint region 13 so as to be electrically connected to the first power modules 114 provided on the corresponding sides of the elevation heating portion 11. The power modules may be provided on both sides in the width direction of the joint region 13, and may extend in the longitudinal direction of the joint region 13 along the boundary line between the joint region 13 and the elevation heating portion 11, so as to be electrically connected to the first power modules 114 on both sides of the elevation heating portion 11.

The bottom heating portion 12 may include a second heating element 123, a second power element 124, and a power interface 14. The second heating member 123 may be located at an intermediate portion of the bottom surface heating portion 12 other than the portion located in the joining region 13. For example, the second heating member 123 may have a strip shape and may be, for example, a plurality of strip-shaped heating members extending in the length direction of the bottom surface heating portion 12, that is, in the horizontal direction of the bottom surface heating portion 12, and the plurality of heating members may be spaced apart from each other by a predetermined distance in a direction perpendicular to the inclined direction. In this case, the second power assembly 124 may be connected to each of the strip heating assemblies from the respective sides of the bottom surface heating portion 12, respectively, to supply the heating power thereto.

Further, the second heating member 123 may also be constituted by a plurality of strip-shaped heating members extending in a direction perpendicular to the inclined direction of the bottom surface heating portion 12 in the plane of the bottom surface heating portion 12, and these heating members may be spaced apart from each other with a predetermined interval in the inclined direction of the bottom surface heating portion 12, and similarly, the second power member 124 may be connected to the power interface 14 on the one hand, and may also be connected to each of the strip-shaped heating members from the respective sides of the bottom surface heating portion 12, respectively, to supply the power received from the power interface 14 to the second heating member 123 to supply the power required for heating.

Further, in the embodiment of the present application, the first heating assembly 113 may also be connected to the second heating assembly 123 through a connection assembly provided outside the junction region, so that power may be received from the second heating assembly 123 connected to the power interface 14, or the first power assembly 112 may also be connected to the power interface 14 or to the second power assembly 122 through the outside of the junction region to receive power therefrom and provide the power to the first heating assembly 113.

Further, in the present embodiment, the second heating member 123 may further include a plurality of U-shaped heating member groups formed of a strip heating member extending in the oblique direction of the bottom surface heating portion 12 and a strip heating member extending in a direction perpendicular to the oblique direction, or a plurality of lattice-shaped heating member groups formed of a strip heating member extending in the oblique direction of the bottom surface heating portion 12 and a strip heating member extending in a direction perpendicular to the oblique direction. And thus, in this case, the second power assembly 124 may be connected to one strip heating assembly from only one side of the bottom surface heating portion 12, for example, and power is sequentially transmitted to all of the heating assemblies connected to each other or sequentially through the strip heating assembly.

In particular, in the present embodiment, the second heating assembly 123 may be distributed only in other portions of the bottom surface heating portion 12 than the portion located within the joining region 13. For example, as shown in fig. 1, the second heating assembly 123 may be distributed only in the middle region, and may be spaced apart from the respective sides by a predetermined distance. This can prevent the second power assembly 124 extending in the side portion from being damaged by the temperature rise also at the time of the heating operation of the second heating assembly 123.

In the present embodiment, the first heating assembly 113 and/or the second heating assembly 123 has a plurality of heating strips extending perpendicular to the width direction of the joint region 13, and the plurality of heating strips are spaced apart at predetermined intervals in the length direction of the joint region 13.

The second power assembly 124 may be disposed along the perimeter of the bottom surface heating portion 12, such as in the outside of the bottom surface heating portion 12 as described above. For example, a protective cover made of an insulating material may be provided on an outer side edge of the bottom surface heating part 12 so that the second power assembly 124 may extend therein, and one or more openings may be provided therein, which may be directed toward the second heating assembly 123 provided at a middle portion of the bottom surface heating part 12. For example, at least one opening toward the second heating assembly may be provided in each side protective case, or at least one opening toward the second heating assembly 123 may be provided in at least one side protective case, so that the power assembly 124 may be connected to the second heating assembly 123 through the opening, and may supply power required for heating the second heating assembly 123.

In the embodiment of the present application, third power components may be provided at both sides of the joint region 13 in the length direction perpendicular to the width direction, connected to the first power component 114 and the second power component 124, respectively. In addition, the power interface 14 may further include a control circuit that may be used to receive control signals from the outside or to generate control signals on its own based on the collected data and to control the power provided to the first heating assembly 112 and/or the second heating assembly 122 through the power interface 14.

The control circuit may be a circuit board enclosed in an insulating case and may be integrated with a power supply providing power and a signal control module processing signals so that the control circuit may transmit power and control signals to the first power component 114 and/or the second power component 124 connected thereto in response to preset program instructions or in response to a user's instruction received from the outside.

In this embodiment of the present application, the control circuit may also include a communication module to communicate with an external device, and may also receive, by means of the communication between the communication module and the external device, an instruction issued by a user or the external device, and send the current heating and/or power supply state to the external device, so as to facilitate the user to view.

Further, at least one first fixing member 115 may be provided on both sides of the elevation heating portion 11 in the length direction of the joint region 13, respectively. The first fixing member 115 may be used to fix such opposite sides of the elevation heating portion 11 so that the elevation heating portion 11 may be fixed to the surface of the calf by the first fixing member 115 when being worn on the calf of a user, and the first fixing member 115 may also change the inner diameter of the barrel-shaped structure formed by the elevation heating portion 11 by adjusting the relative distance between the sides, so that the calf of a user may be adapted to different sizes and shapes, and may also thereby enhance the fit with the calf surface, improving the heating effect.

For example, the first fixing member 115 may include a first snap ring located at one of both sides of the elevation heating portion 11 and a first fixing band located at the other side, and the first fixing band has a width corresponding to an inner width of the first snap ring so that the first fixing band may be penetrated into the first snap ring, and the first fixing band may have a length greater than a distance between both sides of the elevation heating portion, for example, in a length direction of the joint region 13, so that when the foot heating device according to the embodiment of the present application is worn on the foot and lower leg of a user, the fixing of the elevation heating portion 11 to the lower leg of the user may be achieved by the first fixing band in the first fixing member 15 penetrating into the first snap ring and being fixed to the first snap ring or being fixed to the elevation heating portion. For example, in the embodiment of the present application, the end of the first fixing strap may be provided with a tightening end, such as a hair surface constituted by a plurality of upright bristles, and an adhesive surface constituted by a plurality of loops is provided at the first fixing strap or at the corresponding position of the elevation heating portion, so that it is possible to continue to stretch toward the back surface of the elevation heating portion 11 and adhere to the loop adhesive surface provided at the back surface of the elevation heating portion 11 after passing through the snap ring by passing the first fixing strap through the first snap ring and folding back to adhere the hair surface to the loops on the first fixing strap after the user wears the foot heating device according to the embodiment of the present application.

Further, in the embodiment of the present application, the first fixing members 115 may be plural, and may be distributed at different positions in the oblique direction of the elevation heating portion 11, for example, the first fixing members 115 may be two, one of which may be disposed at a position apart from the joint region 13 on the side surface of the elevation heating portion 11, and the other may be disposed at a position close to the joint region 13 on the side surface of the elevation heating portion 11. In this way, the first fixing members 115 provided at a plurality of positions can be used to fix the respective positions of the lower leg, so that the elevation heating portion 11 can be attached to the skin of the lower leg more favorably.

For example, the second fixing member 125 may include a second snap ring located at one of both sides of the bottom surface heating part 12 and a second fixing band located at the other side, and the second fixing band has a width corresponding to an inner width of the second snap ring so that the second fixing band may be penetrated into the second snap ring, and the second fixing band may have a length greater than a distance of the elevation heating part between both sides, for example, in a length direction of the joint region 13, so that when the foot heating device according to the embodiment of the present application is worn on the foot of the user, the fixing of the bottom surface heating part 12 to the foot of the user may be achieved by the second fixing band in the second fixing member 125 penetrating into the second snap ring and being fixed to the second snap ring or to the bottom surface heating part. For example, in the embodiment of the present application, the distal end of the second fixing strap may be provided with a tightening end, such as a hair surface constituted by a plurality of upright bristles, and an adhesive surface constituted by a plurality of loops is provided at the second fixing strap or at the corresponding position of the bottom surface heating portion, so that it is possible to continue to stretch toward the back surface of the bottom surface heating portion 12 and adhere to the loop adhesive surface provided at the back surface of the bottom surface heating portion 12 after passing through the snap ring by passing the second fixing strap through the second snap ring and folding back to adhere the hair surface to the loops on the second fixing strap after the user wears the foot heating device according to the embodiment of the present application.

Further, in the present embodiment, the second fixing members 125 may be plural, and may be distributed at different positions in the oblique direction of the bottom surface heating portion 12, for example, the second fixing members 125 may be two, one of which may be provided at a position apart from the joining region 13 on the side surface of the bottom surface heating portion 12, and the other may be provided at a position close to the joining region 13 on the side surface of the bottom surface heating portion 12.
