Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to heating and insulation equipment. Background Technology

[0002] Body temperature is an external reflection of human health and ranks first among the four vital signs. When a patient needs surgery, the period before, during, and after surgery is called the perioperative period. During the perioperative period, because patients are in the low-temperature environment of the operating room for a long time, and because the patient's hypothalamus loses some function after anesthesia during surgery, and the patient's muscles relax, heat production decreases, making the patient prone to hypothermia, with a core body temperature below 36°C.

[0003] A drop in body temperature not only causes discomfort such as chills, cold extremities, and numbness in patients after surgery, leading to restlessness during the recovery period, but more importantly, it can seriously harm the body's circulatory system, coagulation, and immune mechanisms. The 2017 Expert Consensus on the Prevention and Treatment of Perioperative Hypothermia in Patients clearly states that temperature monitoring of surgical patients should be dynamic and continuous, covering the entire perioperative period, including preoperative, intraoperative, and postoperative recovery. It is recommended to begin temperature monitoring preoperatively as a baseline temperature value to provide a reference for implementing pre-warming measures. Postoperative temperature monitoring is also crucial, as it can assess the effectiveness of intraoperative temperature protection measures and provide a reference for subsequent treatment. Therefore, a device that can warm the lower extremities to maintain the patient's body temperature during the perioperative period when hypothermia occurs is essential. Utility Model Content

[0041] Before implementing the various embodiments of this application, the inventors conducted a detailed study on devices capable of heating the human lower limbs. They discovered that, in order to heat the patient's lower limbs and achieve good heat retention, the usual method involves wrapping the patient's lower limbs with a heating blanket and then sewing the edges. This method does not meet the requirements for rinsing and disinfection during clinical use. Alternatively, to better wrap the patient's lower limbs, the heating device could be designed in a three-dimensional shape that conforms to the shape of the lower leg and foot. However, the manufacturing process for heating devices with specific shapes is too complex, resulting in high costs and hindering mass production.

[0042] Based on this, the inventors of this application attempted to develop a heating and insulation device that can meet the rinsing and disinfection requirements in clinical use, is easy to manufacture, has low cost, and has good heating effect, resulting in the following multiple embodiments.

[0043] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0044] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0047] This application provides a heating and insulation device, which can be a lower limb heating and insulation device, an upper limb heating and insulation device, etc. Taking the lower limb heating and insulation device as an example, this device can wrap around the patient's lower limbs, not only measuring the current body temperature of the lower limbs in real time, but also warming the patient's lower limbs when the temperature is below 36°C, keeping the patient's lower limbs constant between 36°C and 37°C. Furthermore, when the patient's body temperature is in a relatively stable state, the heating and insulation device can be unfolded into a flat position to facilitate disinfection by medical personnel or observation of the patient's lower limb condition. It should be noted that "stable state" here refers to the patient's body temperature being maintained between 36°C and 37°C, not necessarily a constant temperature.

[0048] Specifically, in some embodiments of this application, one possible structure of the heating and insulation device is as follows: the heating and insulation device includes a heating and insulation component 10, which can wrap around the part of the patient requiring heating and insulation, such as the lower limb, and heat and keep the patient's lower limb warm. One possible structure of the heating and insulation component 10 is as follows: the heating and insulation component 10 includes a temperature sensor, a heating element, a controller 30, and an insulation layer, wherein the temperature sensor and the heating element are both coupled to the controller 30. When the heating and insulation component 10 is in contact with the patient's lower limb, the temperature sensor can monitor the temperature of the lower limb in real time and transmit it to the controller 30. The controller 30 communicates with a human-machine interface in real time, and the human-machine interface can display the temperature of the patient's lower limb to medical personnel in real time. The human-machine interface can be a display screen, computer terminal, tablet computer, etc., as long as it can enable information interaction with medical personnel. The connection method can be via a data cable or wireless signal connection, etc. When the temperature sensor detects that the temperature of the patient's lower limb is below 36°C, the controller 30 instructs the heating element to operate to heat the patient's lower limb. When the temperature sensor detects that the patient's lower limb temperature reaches 37°C, the controller 30 controls the heating element to stop heating.

[0049] To facilitate real-time temperature detection of the patient's lower limbs by the temperature sensor and to achieve a good heating effect, in some embodiments of this application, the temperature sensor and heating element are located within the insulation layer, with the heating element and temperature sensor positioned on the inner side of the insulation layer closer to the heating element. The inner side of the heating insulation component 10 is in contact with the patient's lower limb. It is important to note that the heating element and temperature sensor are located inside the heating insulation component 10, biased inwards, rather than on the inner surface of the heating insulation component 10. This is to avoid the sweat from the patient's lower limbs affecting the temperature sensor and heating element, and to prevent the heating element from burning the patient's lower limb skin.

[0050] The insulation layer can be made of sponge, wool blanket, cotton fabric, etc., as long as it can achieve the function of heat preservation and good foldability. The various embodiments of this application do not make specific limitations.

[0051] Furthermore, in some embodiments of this application, the outer surface of the inner and outer surfaces of the heating and insulation component 10, at least the outer surface of the inner side of the heating and insulation component 10, is made of silicone fabric. This makes the inner side of the heating and insulation component 10 softer, allowing it to better conform to the skin of the patient's lower limbs when wrapped, thus providing a better user experience. In addition, the silicone fabric also has good waterproof and corrosion-resistant properties, preventing corrosion and damage from frequent disinfection, ensuring a long lifespan, and preventing disinfectants and sweat from entering the interior of the heating and insulation component 10, thus avoiding damage to the electronic components inside.

[0052] In some embodiments of this application, the controller 30 also has a power cord connected to an external power source, which can supply power not only to the controller 30 but also to the heating element and the temperature sensor. The controller 30 is located on the outer cover surface of the heating and insulation component 10 to avoid irritating the patient when wrapping the patient's lower limbs.

[0053] Understandably, please refer to Figures 1-2 Because the insulation layer and the outer surface of the heating and insulation component 10 are both highly foldable, the heating and insulation component 10 can be laid flat or folded. Therefore, when the patient's lower limbs are in contact with the inner side of the heating and insulation component 10, the component can effectively wrap the patient's feet and calves. This structure is not only low-cost but also easy to manufacture. Since the heating devices provided in the various embodiments of this application are highly malleable, the heating and insulation devices can also be used to heat or insulate the upper limbs, chest, or abdomen. Alternatively, devices that, although different in appearance, have a substantially identical structure to the heating and insulation devices of this application also fall within the scope of protection of this application.

[0054] Taking lower limb warming as an example again, in order to reduce temperature loss in the patient's lower limbs, please refer to some embodiments of this application. Figures 1-2 The heating and insulation device also includes a binding component 20, which is located on the outside of the heating and insulation component 10. The binding component 20 can bind the heating and insulation component 10 tightly to the lower limbs, so that the patient's feet and lower legs do not come into contact with the outside world, thereby reducing heat exchange and achieving a good insulation effect.

[0055] Because the shape of the foot and lower leg differs significantly, to adapt to the shapes of the foot and lower leg and achieve a good wrapping effect, please refer to... Figures 1-2 In some embodiments of this application, one possible structure of the heating and insulation component 10 is that the heating and insulation component 10 includes a second component 11 and a first component 12 connected to each other. The first component 12 and the second component 11 are coaxial along the center line of a first direction. Both the first component 12 and the second component 11 can be folded to form a closed cavity to accommodate the position to be heated. The position to be heated can be the leg or the foot, thereby achieving heating and insulation of the patient's lower limbs.

[0056] The heating effect of a closed cavity on the human body depends on the heating area and the tightness of the wrapping. The inventors of this application conducted heating effect experiments and found that: when a person's feet are immersed in a foot bath, the initial foot temperature is 36.3°C, and the water temperature in the foot bath is 43°C. After 25 minutes of heating, the core temperature of the feet rises by 0.3°C and then remains constant. This can be understood as the water in the foot bath completely enveloping the feet. If only a closed cavity that can accommodate the feet is used, the temperature of the closed cavity is 42°C, and the core temperature only rises by 0.1°C before remaining constant, taking 40 minutes to heat up. If the feet and legs are simultaneously placed in their respective closed cavities and heated together (without being tightly wrapped), the temperature of the closed cavity is 42°C, and the core temperature rises by 0.2°C before remaining constant, taking 15 minutes to heat up. If the feet and legs are placed in their respective closed cavities at the same time, heated together, and tightly wrapped by external force, the temperature of the closed cavity is 42°C, and the effect is quite obvious. The core body temperature rises by 0.3°C and then remains constant, achieving the same effect as heating the feet in a foot bath. However, because this heating method cannot achieve the same tightness of water wrapping, the core body temperature rises more slowly than in a foot bath, taking 45 minutes to heat up.

[0057] Furthermore, in some embodiments of this application, the first component 12 forms a first closed cavity by facing each other on both sides perpendicular to the first direction to accommodate the leg, and the diameter of the first closed cavity can be adjusted according to the thickness of the patient's calf, making operation simple. Along the first direction, such as... Figure 1As shown, the side of the second component 11 away from the first component 12 is folded towards the first component 12 to form a second closed cavity to accommodate the foot. The second closed cavity can completely cover the patient's entire foot without any part being exposed, thereby ensuring the foot's heat preservation and warming effect.

[0058] Please refer to Figures 2-3 When the patient lies down, there will be an angle greater than 90° between the foot and the lower leg. If the part of the heating and insulation component 10 located at the ankle is the same width as the folded part 111, when the heating and insulation component 10 is tied to the patient's lower limb with the binding component 21, the part of the heating and insulation component 10 located at the ankle will exert an outward pulling force on the second component 11, affecting the degree of foot fit and thus affecting the heating effect. Therefore, in some embodiments of this application, the second component 11 includes a folding portion 111 and a connecting component 112. The folding portion 111 folds its side away from the first component 12 toward the first component 12 until it is flush with the other side, forming a second closed cavity that opens toward the first component 12. The second closed cavity is used to accommodate the foot. One side of the connecting component 112 is connected to the folding portion 111, and the other side is connected to the second component 11. The connecting component abuts against the corresponding heating and insulation part. In this embodiment, the heating and insulation part corresponding to the connecting component is the ankle. The following description will continue with the example of the heating and insulation part corresponding to the connecting component being the ankle. The side of the folded part 111 connected to the connecting part 112 is shorter than the side of the connecting part 112 extending in the second direction. The center lines of the first part 12 and the second part 11 in the first direction are coaxial. Therefore, the length of the second part 11 in the second direction perpendicular to the first direction is less than the length of the first part 12 in the second direction. In other words, the connecting part 112 has grooves on both sides perpendicular to the first direction, thereby avoiding the connecting part 112 from affecting the fit of the foot when the heating and heat preservation part 10 is tied to the patient's lower limb with the binding assembly 20, and ensuring good heating and heat preservation effect.

[0059] Please refer to some embodiments of this application. Figures 2-3 Along the second direction, the length of the connecting component 112 is less than the length of the folding portion 111, and the length of the folding portion 111 is less than the length of the second component 11. It is understandable that in order to properly wrap the patient's lower leg, the length of the first component 12 needs to be longer than the length of the folding portion 111. Therefore, setting the length of the first component 12 perpendicular to the first direction to be greater than the length of the folding portion 111 saves material, avoids waste, and prevents the heating pouch from being too large, which would hinder proper foot coverage and affect heating and heat retention.

[0060] In other embodiments of this application, please refer to Figure 1The length of the folded portion of the second component 11 along the second direction is shorter than the length of the first component 12 along both sides of the second direction, and the sides of the first component 12 transition evenly towards the folded portion of the second component 11. Thus, the second component 11 is essentially the shape of two isosceles trapezoids with their shorter sides connected, and the folded portion is the shorter side of the trapezoid. When the second component 11 is folded into the first closed cavity, the opening of the first closed cavity is relatively large, facilitating the placement of the area requiring heating and insulation. The binding assembly 20 can tighten the opening of the first closed cavity after the area requiring heating and insulation is placed, ensuring a good heating and insulation effect. Furthermore, the sides of the second component 11 connected to the first component 12 converge towards each other along both sides of the first direction as the first component 12 folds into the second heating pouch, which can wrap around the patient's ankle, ensuring a heating and insulation effect on the patient's ankle. For some embodiments of this application, please refer to... Figures 2-3 Both the folding part 111 and the second component 11 have connectors 14 on their sides along the first direction, allowing the sides of the first closed cavity and the second closed cavity to be detachably connected. This detachable design of the two closed cavities facilitates the disassembly of the heating bag into a flat foot heating section by medical personnel when the patient's body temperature is constant, making disinfection easier. Further details can be found in the following reference: Figures 1-2 In some embodiments of this application, the heating and insulation component 10 is provided with a sealing edge made by a high-temperature pressing process in the circumferential direction, which not only ensures the aesthetic appearance of the heating and insulation component 10, but also ensures a good waterproof effect.

[0061] In some embodiments, the connector is located on the sealing edges of the second component on both sides along the second direction. The connector 14 can be a first connecting part and a second connecting part that can be matched with each other on both sides of the sealing edges on both sides of the second component 11 along the fold line. The first connecting part and the second connecting part can be connected to each other or separated, so that the sealing edges on both sides of the second component 11 can be connected or separated, which facilitates the formation of a second closed cavity, or the second closed cavity can be disassembled and laid flat. In some embodiments of this application, the first connecting part and the second connecting part can be a female buckle or a female buckle that can be fastened to each other. When the second component 11 is folded to form a heating pocket, the female buckle at the corresponding position can be fastened to the female buckle to connect the sides of the heating pocket together. Optionally, there are multiple sets of combinations of female buckles and corresponding female buckles that are spaced apart to ensure a good connection effect. In some other embodiments of this application, the first connecting part and the second connecting part may also be provided with zipper assemblies that can be pulled and closed on both sides of the sealing edge along the fold line on both sides of the second component 11. When the second component 11 forms a heating pocket, the zipper assemblies on both sides of the heating pocket can be pulled and closed to ensure a good connection effect.

[0062] Whether using a female and male buckle fastening method or a zipper assembly connection method, both facilitate the opening and closing of the heating bag's sides, and the structure is simple and low-cost. Of course, other connection structures can also be used in other embodiments, as long as the reliability of the connection between the heating bag's sides and ease of operation can be achieved. This application does not impose specific limitations on these embodiments.

[0063] Please refer to Figures 1-4 Since the second closed cavity can accommodate the lower leg, and the second closed cavity is surrounded on the lower leg, the length of the first component 12 is greater than the maximum circumference of the patient's lower leg. This facilitates the operation of the heating and insulation component 10 from the flat state to the state of the first closed cavity and the second closed cavity. In the flat state, the first component 12 and the second component 11 of the heating and insulation component 10 are T-shaped.

[0064] Please refer to some embodiments of this application. Figure 4 Both the first component 12 and the second component 11 are provided with binding components 20 to bind the first component 12 tightly to the calf, so that the first closed cavity will not slip off the calf, and to seal the opening of the second closed cavity, so that the second component 11 is bound tightly to the foot, ensuring that the foot has a good heat preservation effect.

[0065] In some embodiments, one possible structure of the binding assembly includes a binding member 21, a fixing buckle 22, and a self-connecting member 23. One end of the binding member 21 is a fixed end, disposed on the heating and insulation component 10, and the other end is a winding end, capable of winding around the outer periphery of the closed cavity. The fixing buckle 22 is disposed on the side of the heating and insulation component 10 away from the binding member 21, aligned with the fixed end. The buckle has a through hole, allowing the winding end to pass through the through hole and then reverse-wind and knot, preventing the binding member 21 from loosening. However, knotting is not only complex to operate but also prone to loosening. Therefore, in some embodiments of this application, the binding assembly 20 further includes a self-connecting member 23, disposed on the winding end. After passing through the through hole, the winding end can self-connect to itself by relying on the self-connecting member 23, which is not only convenient to operate but also less prone to loosening. Of course, the wrapping end can be wrapped one or more times depending on the actual situation. The reverse adhesive fixing method, with the fixing buckle 22 as the fold point, adds a reverse force, making the binding and fixing effect better. The self-connecting part 23 can be a reverse self-adhesive hook and loop fastener or a reverse self-connecting buckle, as long as it can achieve self-connection. This application does not make specific limitations on this.

[0066] Furthermore, in some embodiments of this application, there may be multiple binding components 20 on the heating and insulation device, with the multiple binding components 20 spaced apart, so that the heating and insulation component 10 can be securely bound to the patient's lower limbs.

[0067] Please refer to some embodiments of this application. Figures 1-4 At least one binding component 20 is located at the opening of the second closed cavity. The wrapping end of the binding component 21 can not only wrap around the outer periphery of the second closed cavity, but also wrap around the heating and insulation component at the ankle, ensuring that the heating and insulation component can also be firmly attached to the skin surface of the patient's ankle, thereby increasing the reliability of the wrapping and fixing.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
