Description

Technical Field

[0001] The utility model relates to the technical field of infusion warming, in particular to a wrapping structure, an infusion warming device with the wrapping structure, and an infusion warming system with the above infusion warming device. Background Art

[0002] The liquid infusion warming technology is a medical technology, specifically referring to heating the infusion liquid to a certain temperature during the infusion process, making the infusion liquid entering the human body closer to the body temperature, so as to promote blood circulation, dilate blood vessels, relieve muscle pain, effectively reduce the discomfort of patients during infusion, and improve the infusion comfort of patients.

[0003] Among the performance indicators of the infusion warming device, the final temperature of the medicinal liquid entering the human body is a crucial core content, which is directly related to the user experience of the product and the life safety of patients. Conventional infusion warming devices have a slow heating speed. When used in a low-temperature outdoor environment, it is easy to cause a large difference between the temperature of the finally heated medicinal liquid and the body temperature, making it difficult to meet the comfort requirements of patients. Content of the Utility Model

[0004] In view of this, the utility model aims to propose a wrapping structure to improve the infusion comfort of patients.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] A wrapping structure includes:

[0007] A wrapping main body, which is made of a flexible material and can be operably curled into a cylindrical shape;

[0008] A heating sheet, which is embedded in the wrapping main body to heat the wrapping main body; the heating sheet is a graphene electrothermal film.

[0009] Further, the wrapping main body includes a waterproof layer, a heat radiation reflection layer, a heat preservation layer, and an anti-slip layer stacked from the outside to the inside, and the heating sheet is arranged between the heat radiation reflection layer and the anti-slip layer.

[0010] Further, a first locking member is installed on the wrapping main body. When the wrapping main body is operated to be curled into a cylindrical shape, the first locking member forms a detachable connection after the two opposite ends of the wrapping main body approach each other.

[0011] Further, the first locking member is any one of a sticky buckle, a button, a zipper, a magnetic buckle, a snap button, or a plug buckle.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The wrapping structure described in the present utility model uses graphene heating technology to heat the object to be wrapped. Since graphene has extremely high heat conversion efficiency and is easy to control, after the graphene heating sheet is powered on, the temperature rises extremely fast, and it can quickly heat the wrapping main body. The wrapping main body then transfers the heat to the object to be wrapped, realizing the rapid heating of the object to be wrapped.

[0014] In addition, through the setting of the layer structure of the wrapping main body, after the heating sheet generates heat, the heat radiation reflection layer is not easily penetrated by heat radiation, which can reduce the loss of heat in the direction away from the object to be wrapped; the heat preservation layer plays a heat preservation role and also reduces the loss of heat; the waterproof layer makes the wrapping body more waterproof and weather-resistant during use, and has a longer service life even when used in the wild; the anti-slip layer is in direct contact with the object to be wrapped, making the wrapping main body not easily displaced.

[0015] Another object of the present utility model is to provide an infusion warming device, comprising:

[0016] A first wrapping body, which is arranged at the liquid supply container and can operably wrap around the outer circumferential surface of the liquid supply container;

[0017] A second wrapping body, which is arranged at the liquid medicine transporter and can operably wrap around at least a part of the outer circumferential surface of the liquid medicine transporter;

[0018] The first wrapping body and the second wrapping body adopt the above-mentioned wrapping structure.

[0019] Further, when the second wrapping body can operably form a partial wrapping of the outer circumferential surface of the liquid medicine transporter, the second wrapping body is arranged as at least two spaced apart along the liquid medicine transportation path.

[0020] Further, a top cover is connected to the top end of the first wrapping body. When the first wrapping body can operably be curled into a cylindrical shape, the top cover can operably form a cover for the top of the cylindrical first wrapping body.

[0021] Further, a first bag body with an open top is provided on the inner surface of the first wrapping body. The first bag body is used to hold the bag-shaped liquid supply container, and a liquid outlet for inserting the bag mouth of the bag-shaped liquid supply container is provided at the bottom end of the first bag body.

[0022] Further, a hanging ring for inserting the bottle mouth of the bottle-shaped liquid supply container is provided on the first wrapping body.

[0023] The infusion warming device described in the present utility model is provided with a first wrapping body and a second wrapping body to wrap the liquid supply container and the liquid medicine transporter respectively, which can improve the heating speed of the liquid medicine. Secondly, at least two wrapping bodies are provided on the liquid medicine transporter, which can avoid components such as the drip chamber and the flow rate regulator of conventional liquid medicine transporters like precision filter infusion sets, without affecting the observation and adjustment of the infusion set by medical staff.

[0024] In addition, the present utility model also proposes an infusion warming system, which includes a control module and a temperature detection module for detecting the temperature of the liquid medicine on the supply path. The infusion warming system also includes the above-mentioned infusion warming device.

[0025] In the infusion warming system described in the present utility model, the temperature detection module provides the detected temperature data to the control module. After the control module compares the preset temperatures at various positions on each supply path, it supplies power to each heating sheet. The preset temperature values at various positions on each supply path increase step by step along the liquid medicine flow direction, realizing rapid and uniform heating of the liquid medicine, so that the temperature of the liquid medicine when entering the human body is closer to the body temperature.

[0049] The following will refer to the attached Figure 1-7 and describe the present utility model in detail in conjunction with embodiments.

[0050] Embodiment 1

[0051] This embodiment relates to a wrapping structure 1, the structure is as Figure 1 shown, including a wrapping main body 101 and a heating sheet 102. The wrapping main body 101 is made of a flexible material and can be operably curled into a cylindrical shape. The heating sheet 102 is embedded in the wrapping main body 101 and is a graphene electric heating film, which can be curled with the wrapping main body 101 and is used to heat the wrapping main body 101, and then the wrapping main body 101 transfers the heat to the object to be wrapped, realizing the heating effect of the wrapping structure 1 on the object to be wrapped.

[0052] The heating sheet 102 utilizes the graphene electrothermal principle. Due to its extremely high thermal conductivity coefficient, graphene can achieve an extremely fast heating speed and is suitable for application scenarios that require rapid heating. In addition, most of the heat generated during the graphene heating process is propagated in the form of far-infrared rays, which can quickly raise the temperature of the wrapping main body 101 and rapidly transfer heat to the object to be wrapped. The far-infrared heating method also has the advantages of no noise and no harmful radiation, and is more suitable for medical field applications. The graphene electric heating film is first made by compounding graphene and polyester into a conductive composite film, then setting current-carrying strips, and finally covering an insulating protective layer.

[0053] The heating sheet 102 has two electrodes, an integrated circuit is provided between the two electrodes, and a power line 1021 is led out from the integrated circuit. The power line 1021 penetrates through the wrapping main body 101 and is provided with a waterproof plug. After the waterproof plug of the power line 1021 is connected to the power supply, the heating sheet 102 can quickly heat up and perform heating operations.

[0054] Specifically, the side of the wrapping main body 101 in contact with the object to be wrapped in the wrapped state is the inner side, and the opposite side is the outer side. The wrapping main body 101 includes a waterproof layer 1011, a heat radiation reflection layer 1012, a heat preservation layer 1013, and an anti-slip layer 1014 stacked from the outside to the inside, and the heating sheet 102 is arranged between the heat radiation reflection layer 1012 and the anti-slip layer 1014.

[0055] Since the heating sheet 102 is in the shape of a thin sheet, the heat generated is mainly dissipated on both sides in its thickness direction. The heat generated inside the heating sheet 102 is transferred to the object to be wrapped through the anti-slip layer 1014; the heat generated outside is reflected inward by the heat radiation reflection layer 1012, effectively reducing the heat loss from the outside, so that the wrapping structure 1 has a good heating and heat preservation effect.

[0056] The waterproof layer 1011 is made of a waterproof functional material. In this embodiment, it is preferably made of waterproof Oxford cloth, which has good waterproof performance and wear resistance, has anti-fouling ability and is easy to clean, and can improve the service life of the wrapping structure 1.

[0057] The heat radiation reflection layer 1012 is made of a material that can reflect heat radiation. In this embodiment, highly efficient heat radiation-proof composite aluminum foil is preferably used as the heat radiation reflection layer 1012. The highly efficient heat radiation-proof composite aluminum foil has the characteristic of high reflectivity, and its high reflectivity enables it to reflect most of the heat radiation and reduce the heat loss from the inside of the wrapping main body 101 to the outside.

[0058] The heat preservation layer 1013 is made of a heat preservation material. In this embodiment, it is preferably made of lightweight composite aerosol material. The aerosol material has a large specific surface area and surface energy. This structure enables the aerosol to effectively absorb and scatter the radiation in the infrared band, thereby blocking the transfer of heat radiation; at the same time, there are a large number of tiny pores and air layers between the particles in the aerosol, and these pores and air layers play a very good role in hindering heat conduction. Preferably, the heating sheet 102 is embedded on the side of the heat preservation layer 1013 facing the anti-slip layer 1014, which is beneficial to the transfer of heat to the anti-slip layer 1014.

[0059] In this embodiment, the waterproof layer 1011, the heat radiation reflection layer 1012, the heat preservation layer 1013, and the anti-slip layer 1014 are connected into a whole by sewing.

[0060] A preferred way in this embodiment is that a first locking member 103 is further installed on the wrapping main body 101. When the wrapping main body 101 is operated to be curled into a cylindrical shape, the first locking member 103 constitutes a detachable connection after the two opposite ends of the wrapping main body 101 approach each other. Setting the first locking member 103 on the wrapping main body 101 can make the heating effect of the wrapping main body 101 better. When using the wrapping main body 101 for the wrapping action, its anti-slip layer 1014 is attached to the object to be wrapped, and the two opposite ends of the wrapping main body 101 on both sides of the object to be wrapped are curled towards the object to be wrapped. After the wrapping main body 101 is closely attached to the object to be wrapped, the above two opposite ends are superposed on the surface of the object to be wrapped, and then the first locking member 103 is used to fix the positions of the above two opposite ends.

[0061] Specifically, the first locking member 103 is any one of a hook-and-loop fastener, a button, a zipper, a magnetic buckle, a snap fastener or a plug fastener. The hook-and-loop fastener, the button, the zipper, the magnetic buckle, the snap fastener or the plug fastener is composed of two detachable parts. By installing one part at each of the two opposite ends of the wrapping body 101, the detachable wrapping function of the wrapping body 101 can be realized, which is convenient for quick disassembly.

[0062] In a feasible form of this embodiment, the first locking member 103 is a hook-and-loop fastener, including a first fuzzy surface 1031 and a first hook surface 1032. The first fuzzy surface 1031 and the first hook surface 1032 are respectively arranged on the inner side surface and the outer side surface of the wrapping body 101, and are respectively located at the two opposite ends of the wrapping body 101. Preferably, the first fuzzy surface 1031 is sewn on the outer side surface of the wrapping body 101, and the first hook surface 1032 is sewn on the inner side surface of the wrapping body 101. The width of the first fuzzy surface 1031 is greater than the width of the first hook surface 1032, so that the wrapping structure 1 can wrap objects to be wrapped of different sizes.

[0063] In addition, a plurality of heating sheets 102 can be arranged in the wrapping body 101, so that a single wrapping body 101 can wrap and heat a longer object to be wrapped.

[0064] Embodiment 2

[0065] This embodiment relates to an infusion warming device, as Figures 2-6 shown, including a first wrapping body 1-1 and a second wrapping body 1-2. The first wrapping body 1-1 is arranged at the liquid supply container and can operably wrap around the outer circumferential surface of the liquid supply container. The second wrapping body 1-2 is arranged at the liquid medicine transporter and can operably wrap around at least part of the outer circumferential surface of the liquid medicine transporter. Both the first wrapping body 1-1 and the second wrapping body 1-2 adopt the wrapping structure 1 in Embodiment 1.

[0066] The separate arrangements of the first wrapping body 1-1 and the second wrapping body 1-2 can enable the liquid medicine to be heated multiple times in the supply path, with a relatively fast heating speed. At the same time, the separate arrangement of multiple wrapping structures 1 can also make the components of the infusion warming device have better replaceability.

[0067] This embodiment takes an infusion bottle or an infusion bag as the liquid supply container and a precision filter infusion set as the liquid medicine transporter to illustrate the infusion warming device. The liquid supply container and the liquid medicine transporter can also adopt other different instruments or devices with the same functions.

[0068] The main body of the precision filter infusion set is an infusion tube. Along the liquid medicine flow direction on the infusion tube, there are mainly a bottle stopper puncture device, a drip chamber, a precision filter, a flow rate regulator and a venous needle.

[0069] The first wrapper 1-1 is used to wrap an infusion bottle or an infusion tube. The infusion bottle and the infusion tube are in an inverted state with the outlet facing downwards in the normal use state. One end of the first wrapper 1-1 that is close to the bottle mouth or the bag mouth after wrapping the liquid supply container is defined as its bottom end, and the opposite end is defined as its top end.

[0070] One corner is removed from each of the two winding ends of the first wrapper 1-1 close to the bottom end, so that when the bottom end of the first wrapper 1-1 wraps a conical object, such as the conical variable diameter part of an infusion bottle, it can fit more closely.

[0071] An insertion opening 1015 is provided on the inner side surface of the first wrapper 1-1. The insertion opening 1015 communicates with the gap between the anti-slip layer 1014 and the heat preservation layer 1013. The heating sheet 102 is placed into the first wrapper 1-1 through the insertion opening 1015, and the power cord 1021 passes downward through the first wrapper 1-1. The first wrapper 1-1 is provided with a zipper at the insertion opening 1015, which can be quickly disassembled and replaced when the heating sheet 102 needs to be replaced.

[0072] Specifically, an upper cover 2 is connected to the top end of the first wrapper 1-1. When the first wrapper 1-1 is operably curled into a cylindrical shape, the upper cover 2 can operably form a cover for the top of the cylindrical first wrapper 1-1. A second locking member 7 is provided between the upper cover 2 and the first wrapper 1-1. The second locking member 7 can be any one of a sticky fastener, a button, a zipper, a magnetic buckle, a snap button or a plug buckle. In this embodiment, it is preferably a sticky fastener, including a second plush surface 701 and a second hook surface 702.

[0073] The upper cover 2 is used to cover the top after the first wrapper 1-1 wraps the liquid supply container, which can not only improve the heat preservation performance of the first wrapper 1-1, but also play a protective role for the internal liquid supply container, making the liquid supply container not easily damaged by bumping.

[0074] In a feasible form of this embodiment, the upper cover 2 and the first wrapper 1-1 are integrally formed. The upper cover 2 also has a layer structure such as the wrapping main body 101 and can be folded and bent. The upper cover 2 is set to be semi-circular, which is convenient for covering the top end of the first wrapper 1-1. The inner side of the first wrapper 1-1 is the inner side of the upper cover 2. The second plush surface 701 is sewn on the outer side surface top end of the first wrapper 1-1, and the second hook surface 702 is sewn on the inner side surface of the upper cover 2. After the first wrapper 1-1 wraps the liquid supply container, when the upper cover 2 is covered, the second hook surface 702 and the second plush surface 701 are adhered, and the upper cover 2 can be kept in the covered state. Edging 6 is sewn on the edges of the first wrapper 1-1 and the upper cover 2. The edging 6 makes the edges of the first wrapper 1-1 and the upper cover 2 smoother and not easily damaged due to friction.

[0075] Specifically, a restraint band 9 is detachably connected between two opposite ends of the first wrapper 1-1 for winding, which is used to play an auxiliary fixing role when the first wrapper 1-1 wraps the liquid supply container.

[0076] A third locking member 8 is provided on the tightening belt 9. The third locking member 8 can be any one of a Velcro, a button, a zipper, a magnetic buckle, a snap button or a snap fastener. In this embodiment, it is preferably a Velcro, including a third fuzzy surface 801 and a third hook surface 802, which is more convenient to use. One end of the tightening belt 9 is sewn to the outer side surface of the first wrapping body 1-1 and is provided with the third hook surface 802, and the other end on the same side of the tightening belt 9 is provided with the third fuzzy surface 801.

[0077] The tightening belt 9 is also equipped with a buckle 901. The buckle 901 is sewn on the outside of the top wrapping body. When the tightening belt 9 is in use, the first wrapping body 1-1 wraps the liquid supply container. The tightening belt 9 passes through the buckle 901 after bypassing the overlapping part of the two opposite ends of the first wrapping body 1-1, and then is tightened and wound back to bond the third fuzzy surface 801 and the third hook surface 802, so as to realize the auxiliary fixation of the first wrapping body 1-1. In this embodiment, there are two groups of the tightening belt 9 and the buckle 901, which are arranged at intervals, one above the other, on the first wrapping body 1-1.

[0078] Specifically, a hanging ring 4 is provided on the first wrapping body 1-1 for the bottle mouth of the bottle-shaped liquid supply container to penetrate. Taking an infusion bottle as an example, after the bottle mouth of the infusion bottle passes through the hanging ring 4, the hanging ring 4 will support the infusion bottle, making it not easy for the infusion bottle to fall out of the first wrapping body 1-1. In this embodiment, the hanging ring 4 is a semi-circular soft ring sewn at the bottom end of the first wrapping body 1-1 with double lines, and can be made of cloth material, rubber material or plastic material.

[0079] Some liquid supply containers are flexible bags. As the liquid medicine in the bag gradually flows out, it is easy to loosen after being wrapped by the first wrapping body 1-1. To solve this problem, a first bag body 3 with an open top is provided on the inner surface of the first wrapping body 1-1. The first bag body 3 is used to hold the bag-shaped liquid supply container, and a liquid outlet 301 for the bag mouth of the bag-shaped liquid supply container to penetrate is provided at the bottom end of the first bag body 3. Taking an infusion bag as an example, when using the first wrapping body 1-1 to wrap the infusion bag, the infusion bag is loaded into the first bag body 3 with the bag mouth facing down, and the bag mouth passes through the liquid outlet 301 downward, so that the infusion bag can be firmly set in the first wrapping body 1-1 and is not easy to fall off.

[0080] A second bag body 10 is also sewn in the middle of the outer side surface of the first wrapping body 1-1. The second bag body 10 has an upward opening and is used to hold identification cards such as medical records. A hanging ring 11 is also sewn on the top of the outer side surface of the first wrapping body 1-1. The hanging ring 11 is located at the top end of the first wrapping body 1-1 and is used to hook the hook of the infusion rack, so that the liquid supply container can be suspended at a higher position, which is beneficial to the flow of the liquid medicine.

[0081] Specifically, when the second inclusions 1-2 are operably configured to partially wrap the outer surface of the liquid medicine transporter, at least two second inclusions 1-2 are arranged at intervals along the liquid medicine transportation path. Arranging at least two inclusions can function to avoid components on the liquid medicine transporter. For example, it can avoid the drip chamber, flow rate regulator, etc. on the precision filtration infusion set, so that when the infusion warming device in this embodiment is in use, it does not affect medical staff's observation of the drip chamber or adjustment of the flow rate regulator.

[0082] In this embodiment, there are two second inclusions 1-2, which are divided into an upper second inclusion 1-2 and a lower second inclusion 1-2 along the liquid medicine flow direction. The upper second inclusion 1-2 wraps the infusion tube from the bottle stopper puncture device to the drip chamber section, and the lower second inclusion 1-2 wraps the infusion tube from the drip chamber to the venous needle section.

[0083] In this embodiment, there are two ways to connect the heating sheets 102 in the first inclusion 1-1 and the second inclusion 1-2 to the power supply. The first way is the parallel connection method in which each heating sheet 102 is respectively connected to the power supply through its own power cord 1021; the second way is the series connection method in which the power supply, the lower second inclusion 1-2, the upper second inclusion 1-2, the first inclusion 1-1, and the power supply are connected in series in sequence. This embodiment preferably adopts the second series connection method, which can make the wiring more concise and the infusion warming device more convenient to disassemble and assemble.

[0084] Embodiment Three

[0085] This embodiment relates to an infusion warming system, as Figure 7 shown, including a control module 5, a temperature detection module for detecting the temperature of the liquid medicine on the supply path, and the infusion warming device in Embodiment Two.

[0086] The temperature detection module is arranged in both the first inclusion 1-1 and the second inclusion 1-2, and is embedded on the side of the heat insulation layer 1013 facing the anti-slip layer 1014. Each heating sheet 102 is equipped with a temperature detection module. The temperature detection module includes a temperature measurement probe and a supporting temperature measurement circuit. The temperature measurement probe can measure the temperature of the contact part between the anti-slip layer 1014 and the object to be wrapped. The control module 5 can supply power to the corresponding heating sheet 102 according to the data measured by the temperature measurement probe.

[0087] This embodiment preferably uses a rare alloy thermocouple probe, and the measured temperature value is relatively accurate. The temperature measurement probe and the supporting heating sheet 102 share the power cord 1021. The power cord 1021 is connected to the control module 5, and the control module 5 realizes power supply and communication to the temperature measurement probe through the power cord 1021.

[0088] This embodiment takes an infusion bottle as the liquid supply container and a precision filtration infusion set as the liquid medicine transporter to illustrate the infusion warming system:

[0089] The first package 1-1 wraps the infusion bottle, the second package 1-2 in the upper part wraps the infusion tube from the drip chamber to the bottle stopper puncture device section, and the second package 1-2 in the lower part wraps the infusion tube from the drip chamber to the venous needle section. All temperature measurement probes are arranged at one end of the package close to the outflow of the liquid medicine in the package, so that the measured temperature value is closer to the actual temperature value of the liquid medicine after being heated.

[0090] A common preset value is set at each temperature measurement probe. When the temperature value measured by the temperature measurement probe is lower than the preset value, the control module 5 supplies power to the heating sheet 102 corresponding to the temperature measurement probe; when the temperature value measured by the temperature measurement probe is higher than or equal to the preset value, the control module 5 stops supplying power to the heating sheet 102 corresponding to the temperature measurement probe, realizing the temperature control of the liquid medicine heating.

[0091] Based on the optimal infusion temperature of the human body being 35°C - 37°C, a preset value between 35°C - 37°C, such as 36°C, can be set at all temperature measurement probes.

[0092] Embodiment 4

[0093] Embodiment 4 of the present application relates to an infusion warming system, which is different from Embodiment 3 in that the preset values at each temperature measurement probe are different. Specifically, a stepped increasing preset value is set for each temperature measurement probe along the liquid medicine flow direction of the liquid medicine supply path. When the temperature value measured by the temperature measurement probe is lower than the preset value at that place, the control module 5 supplies power to the heating sheet 102 corresponding to the temperature measurement probe; when the temperature value measured by the temperature measurement probe is higher than or equal to the preset value at that place, the control module 5 stops supplying power to the heating sheet 102 corresponding to the temperature measurement probe.

[0094] Through the above heating method, the liquid medicine will be heated in sections during the flowing process, making the liquid medicine temperature rise evenly, and the heating efficiency is relatively high. At the same time, the situation of overheating of the liquid medicine is not likely to occur. Based on the optimal infusion temperature of the human body being 35°C - 37°C, the following is an example:

[0095] Set the preset value at the temperature measurement probe in the second package 1-2 in the lower part to be 36°C, the preset value at the temperature measurement probe in the second package 1-2 in the upper part to be 31°C, and the preset value at the temperature measurement probe in the first package 1-1 to be 26°C.

[0096] Embodiment 5

[0097] Embodiment 5 of the present application relates to an infusion warming system, which is different from Embodiment 4 in that the control module 5 includes a PID controller (Proportional-Integral-Derivative controller), and the heating power of each heating sheet 102 can be adjusted by the PID controller according to the temperature value collected by the temperature measurement probe, and the heating power is distributed to each heating sheet 102.

[0098] The PID controller is a common feedback loop component in industrial control applications. In this embodiment, the PID controller compares the collected temperature data with a preset value, and then uses the obtained difference to calculate a new power input value. The purpose of this new power input value is to make the temperature at the measured part of the temperature measuring probe reach or maintain the preset value. The characteristic of the PID controller is that it can adjust the heating power input value according to historical data and the occurrence rate of differences, so that the finally heated temperature of the liquid medicine can be more stable and the heating efficiency is also higher. Based on the most comfortable infusion temperature for the human body being 35°C - 37°C, the following is an example:

[0099] Through the PID controller, the preset value at the temperature measuring probe in the lower second package 1-2 is set in the range of 35°C - 37°C, the preset value at the temperature measuring probe in the upper second package 1-2 is set in the range of 30°C - 35°C, and the preset value at the temperature measuring probe in the first package 1-1 is set in the range of 25°C - 30°C.

[0100] When the control module 5 is started, the PID controller preferentially distributes all heating power to the heating sheet 102 in the lower second package 1-2. If the temperature value measured by the temperature measuring probe in the lower second package 1-2 rises to 35°C - 37°C, the PID controller maintains the temperature at this place and distributes the excess heating power to the heating sheet 102 in the upper second package 1-2; if the temperature measured by the temperature measuring probe in the upper second package 1-2 rises to 30°C - 35°C, the PID controller maintains the temperature at this place and distributes the excess heating power to the heating sheet 102 in the first package 1-1; if the temperature measured by the temperature measuring probe in the first package 1-1 rises to 25°C - 30°C, the PID controller maintains the temperature at this place and the PID controller reduces the output power.

[0101] In addition, a limit working temperature limit of 42°C is set for all temperature measuring probes. When the temperature value measured by any temperature measuring probe reaches 42°C, the PID controller immediately interrupts the power supply to all heating sheets 102 to prevent the situation where the infusion temperature is too high and causes irritation and damage to the patient's blood vessels and tissues. The situation where the infusion temperature is too high may also lead to drug decomposition or deterioration, affecting the drug efficacy and even damaging the patient's physical health.

[0102] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
