Abstract
Description
Technical Field
[0001] The utility model relates to the field of keeping newborns warm, in particular to a self-heating warming wrap. Background Art
[0002] Newborns have the characteristics of fast heat dissipation from the body surface and imperfect body temperature regulation center. When newborns are delivered from amniotic fluid at 37℃ and enter the room temperature environment of about 25℃, if effective warming measures are not taken immediately, body heat can be lost through radiation, conduction, convection, water evaporation, etc., which can easily lead to neonatal hypothermia (body temperature <36.5℃), which is not conducive to the health of newborns. Neonatal hypothermia will increase the metabolism of the newborn body, increase tissue oxygen consumption, lead to hypoxia, acidosis, and even neonatal scleredema and other serious complications. For every 1℃ drop in the newborn's body temperature, the mortality rate of the newborn will increase by 28%. At the same time, it is also important to avoid excessive temperature increase (>38℃) and reduce the potential adverse effects caused by high temperature. Therefore, it is very necessary to do a good job of neonatal temperature management during delivery. Efforts should be made to help newborns reach the ideal body temperature and maintain a constant temperature immediately after delivery, so as to help newborns better adapt to the living environment outside the mother's body and promote health.
[0003] In the relevant technologies, the technical means to maintain the body temperature of newborns mainly include electric heating, physical covering, wrapping with polyethylene film, raising the temperature of the environment and equipment, etc., such as the newborn warming emergency kit that uses external power supply for electric heating, and also warming boxes, warm clothes, etc.
[0004] However, in the warming technology provided in the related art, if the electric heating method uses a mobile power supply, it will be limited by the power of the mobile power supply, and the heating power will also be limited by the output power of the mobile power supply. If the electric heating method uses a fixed power supply for heating, it will be detrimental to practical convenience. As for the warming methods such as physical covering and wrapping with polyethylene film, they will rely on the newborn's own heat generation, and the temperature field cannot be controlled, and the warming effect is poor.

[0020] In the disclosed embodiment, the self-heating warm wrap includes a warming structure layer, an isolating heat-conducting structure layer, a heating structure layer and a packaging layer, wherein the warming structure layer, the isolating heat-conducting structure layer and the heating structure layer are located inside the packaging layer, and the isolating heat-conducting structure layer is located between the warming structure layer and the heating structure layer. When it is necessary to keep the newborn warm, the packaging layer is opened.

On the other hand, the heating method in the embodiment of the present disclosure does not require an external power supply. When needed, the thermal insulation layer can be heated to the target temperature anytime and anywhere, which is more convenient to use. On the other hand, the thermal insulation layer and the heating structure layer are separated by an isolating heat-conducting layer, which can prevent the medium in the heating structure layer from contacting the thermal insulation layer, and can prevent the medium from affecting the skin of the newborn. At the same time, since electric heating is not used, the electromagnetic radiation caused by the electric heating method can also be prevented from affecting the newborn.

[0029] Figure 1 A schematic structural diagram of a self-heating warming wrap provided in an embodiment of the present disclosure. Figure 1 This is a front view of the self-heating warming wrap, see Figure 1 The self-heating warming wrap is encapsulated in a packaging layer 13, and the self-heating warming wrap comprises: a warming structure layer 10, an isolating heat-conducting structure layer 11 and a heating structure layer 12;
[0030] The insulating heat-conducting structural layer 11 is located between the thermal insulation structural layer 10 and the heating structural layer 12; the heating structural layer 12 is used for releasing heat by chemically reacting when it comes into contact with air after the packaging layer 13 is opened.
[0031] In the disclosed embodiment, the self-heating warm wrap includes a warming structure layer, an isolating heat-conducting structure layer, a heating structure layer and a packaging layer, wherein the warming structure layer, the isolating heat-conducting structure layer and the heating structure layer are located inside the packaging layer, and the isolating heat-conducting structure layer is located between the warming structure layer and the heating structure layer. When it is necessary to keep the newborn warm, the packaging layer is opened. After the packaging layer is opened, the heating structure layer undergoes a chemical reaction to release a large amount of heat, which is transferred to the warming structure layer through the isolating heat-conducting structure layer, so that the temperature of the warming structure layer rises. After the temperature of the warming structure layer rises to the target temperature, the warming structure layer can be separated from the isolating heat-conducting structure layer, and the moisture on the surface of the newborn body can be wiped with one side of the warming structure layer close to the isolating heat-conducting structure layer, and then the newborn body temperature can be maintained at a normal level with the other side of the warming structure layer wrapped around the newborn. For the self-heating warm wrap in the disclosed embodiment, on the one hand, the warming structure layer is heated by chemical heating. The heating method of chemical heating generates large heat, high heat density, and high heating rate, and the warming structure layer can be quickly heated to the target temperature. The medium in the heating structure layer is evenly distributed, which can make the temperature field more uniform, so that the temperature of the heated thermal insulation layer is more uniform, which is more conducive to the warming effect of the thermal insulation layer on the newborn. On the other hand, the heating method in the embodiment of the present disclosure does not require an external power supply. When needed, the thermal insulation layer can be heated to the target temperature anytime and anywhere, which is more convenient to use. On the other hand, the thermal insulation layer and the heating structure layer are separated by an isolating heat-conducting layer, which can prevent the medium in the heating structure layer from contacting the thermal insulation layer, and can prevent the medium from affecting the skin of the newborn. At the same time, since electric heating is not used, the electromagnetic radiation caused by the electric heating method can also be prevented from affecting the newborn.
[0032] In the disclosed embodiment, the self-heating thermal wrap is folded and encapsulated in the packaging layer 13 , the thermal insulation structure layer 10 wraps the heating structure layer 12 , and the insulating heat-conductive structure layer 11 is located between the thermal insulation structure layer 10 and the heating structure layer 12 .
[0033] In the embodiment of the present disclosure, the thermal insulation structure layer, the insulating heat conductive structure layer and the heating structure layer of the above-mentioned shape are provided, and the thermal insulation structure layer wraps the heating structure layer, which can further reduce the loss of heat generated by the heating structure layer, improve the heating effect of the heating structure layer, and further improve the heating rate.
[0034] In the disclosed embodiment, the thickness of the heating structure layer is 1 to 3 cm.
[0035] Exemplarily, the thickness of the heating structure layer is 1.5 cm.
[0036] In the disclosed embodiment, the heating structure layer heats the thermal insulation structure layer by chemical heating. The use of the heating structure layer with the above thickness can ensure that there is enough medium to react, so as to ensure that the heating structure layer can generate more heat.
[0037] In the disclosed embodiment, the heating structure layer is a heating pad.
[0038] In the embodiment of the present disclosure, a heating pad can be used as the heating structure layer. The heating pad has a high heating rate and is easy to use.
[0039] In the embodiment of the present disclosure, the isolation heat-conducting structural layer 11 includes an isolation heat-conducting film.
[0040] In the embodiment of the present disclosure, the isolation thermal conductive structure layer made of thin film material can have good isolation thermal conductive performance.
[0041] In the disclosed embodiment, the thickness of the isolated heat-conducting structure layer is 0.1-0.3 cm.
[0042] Exemplarily, the thickness of the isolated heat-conducting structure layer is 0.15 cm.
[0043] In the embodiment of the present disclosure, using an isolating heat-conducting structural layer of the above-mentioned thickness can ensure that the isolating heat-conducting structural layer is not easy to break, thereby ensuring that the isolating heat-conducting structural layer can effectively separate the thermal insulation structural layer and the heating structural layer, avoiding the chemical substances of the heating structural layer from adhering to the surface of the thermal insulation structural layer, and avoiding the effects of the chemical substances on the newborn.
[0044] In the disclosed embodiment, a temperature measuring structure layer 14 is further provided on the surface of the thermal insulation structure layer 10 , and the temperature measuring structure layer 14 may be a temperature measuring test paper.
[0045] In the disclosed embodiment, by setting a temperature measuring paper on the surface of the thermal insulation structure layer and obtaining the color of the temperature measuring paper, it is possible to determine whether the temperature of the thermal insulation structure layer meets the requirements, and since the thermal insulation structure layer uniformly wraps the heating structure layer, when the heating structure layer heats the thermal insulation structure layer, the temperature of each position of the heating structure layer rises uniformly. Therefore, by obtaining the temperature of one position on the surface of the thermal insulation structure layer, it is possible to determine whether the overall temperature of the thermal insulation structure layer meets the requirements.
[0046] Figure 2 A schematic structural diagram of another self-heating thermal wrap provided in an embodiment of the present disclosure. Figure 2 It is a top view of the self-heating thermal wrap.
[0047] In the disclosed embodiment, the shape of the thermal insulation structure layer when unfolded into a plane is a rectangle, and the size of the rectangle is 75 cm×75 cm.
[0048] In the disclosed embodiment, the use of the thermal insulation structure layer of the above-mentioned size can ensure that the thermal insulation structure layer can better wrap the newborn and ensure the thermal insulation effect of the thermal insulation structure layer.
[0049] It is worth mentioning that Figure 2 The thermal insulation structure layer 10 is not fully unfolded into a plane.
[0050] It is worth noting that the size of the thermal insulation structure layer 10 can be set as needed.
[0051] In the embodiment of the present disclosure, the temperature measuring structure layer 14 is disposed in the central area of the upper surface of the folded thermal insulation structure layer 10 .
[0052] Figure 3 This is a schematic diagram of a thermal insulation structure layer provided by an embodiment of the present disclosure. Figure 3 The thermal insulation structure layer includes a water-absorbing layer 101 and a thermal insulation layer 102 which are stacked.
[0053] In the disclosed embodiment, the water absorbing layer 101 is close to the insulating heat-conducting structure layer, and the water absorbing layer 101 and the heat-insulating layer 102 are detachable.
[0054] In the embodiment of the present disclosure, a detachable water-absorbing layer and a thermal insulation layer are provided in the thermal insulation structure layer. When the temperature of the thermal insulation structure layer rises to the target temperature, the water-absorbing layer can be used to wipe the moisture on the body surface of the newborn. Then, the water-absorbing layer and the thermal insulation layer are separated, and the thermal insulation layer is used to keep the newborn warm to prevent the moisture on the body surface of the newborn from affecting the body temperature of the newborn.
[0055] In the disclosed embodiment, the thermal insulation layer is a pure cotton layer, and the water-absorbing layer is a plant fiber layer.
[0056] In the disclosed embodiment, the pure cotton layer has good thermal insulation performance, and the plant fiber has good water absorption performance. Using the above materials as the thermal insulation layer and the water absorption layer can ensure the thermal insulation effect of the thermal insulation layer and the water absorption effect of the water absorption layer.
[0057] In the disclosed embodiment, the thickness of the water absorbing layer is 0.3 to 1 cm, and the thickness of the thermal insulation layer is 0.5 to 2.5 cm.
[0058] Exemplarily, the thickness of the water absorbing layer is 0.5 cm, and the thickness of the thermal insulation layer is 2 cm.
[0059] In the disclosed embodiment, the water absorbing layer is only used to absorb moisture from the surface of the newborn body, so the thickness is set slightly thinner, on the one hand, to ensure a low production cost, and on the other hand, to ensure the water absorbing effect of the water absorbing layer. The thermal insulation layer is used for warmth, and the thickness is set slightly thicker to ensure a better warmth-keeping effect of the thermal insulation layer.
[0060] In the disclosed embodiment, when the newborn is about to be delivered, the midwife opens the packaging layer of the self-heating thermal wrap, and the chemical substances in the heating structure layer start to generate heat after coming into contact with the air. When the temperature indicator paper changes color and the thermal structure layer reaches the use temperature, the thermal structure layer is taken out from the packaging layer to wrap the newborn, and the newborn is first wiped dry with the inner water-absorbing layer with strong absorbency, and the inner water-absorbing layer is discarded. The newborn is wrapped with the outer thermal layer with strong thermal insulation to achieve the effect of full warmth preservation.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
