The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Referring to Figure 1, there is shown a schematic view of a flexible heating device 1 in accordance with a preferred embodiment of the present invention, wherein the flexible heating device 1 is in a flat state. The flexible heating device 1 includes a flexible body 12, a first heating element 14, a first fixing element 16, and a second fixing element 18. The flexible body 12 has an inner surface 12a and an outer surface 12b. The inner surface 12a includes a first surface area 122, a second surface area 124 and a third surface area 126, wherein the second surface area 124 is relatively far away. The first surface region 122 is partially a second surface region outer side 124a, and the first surface region 122, the second surface region 124, and the third surface region 126 extend along a longitudinal direction 10 of the flexible heating device 1. The regions 122, 124, and 126 are for convenience of description, and the boundaries therebetween are directly indicated by broken lines, and the present invention is not limited thereto. In practice, the flexible body 12 can be a silicone, rubber or other engineering plastic product, but the invention is not limited thereto. The flexible body 12 has two slots 122a, 122b in the first surface region 122, extending substantially along the major axis direction 10. The two slots 122a, 122b may have the same or different cross-sectional profiles to accommodate the same or respectively Tubes 2a, 2b of different diameters (shown in phantom in Figure 1).

The first heating element 14 is disposed on the second surface region 124 and extends along the long axis direction 10 and has flexibility to deform the first heating element 14 along the long axis direction 10, in practice, the first heating The component 14 can be a strip of heating sheet, such as a silicone heating sheet, a polyimide heating sheet, or other heating that can be bent into the flexible body 12, but the invention does not limit. also, In the present embodiment, the first heating element 14 is directly attached to the second surface area 124, but the invention is not limited thereto. For example, the flexible body 12 can form a recess in the second surface region 124 to receive the first heating element 14, or to insert the first heating element 14 into the second surface region 124, such as insert molding, such that The second surface area 124 can still remain flat.

The first fixing element 16 is disposed on the third surface area 126; the second fixing element 18 is disposed on the outer surface 12b, and its position on the outer surface 12b is indicated by a dashed box. In this embodiment, the first fixing component 16 and the second fixing component 18 each include a plurality of fixed component parts 162 and 182 correspondingly disposed, and the fixed component parts 162 and 182 are substantially arranged along the longitudinal direction 10, respectively. The detail parts 162, 182 may correspond to one selected from the group consisting of a devil's felt, a buckle, a magnetic clasp, or other member having a mutual bond. As shown in Fig. 1, the flexible heating device 1 is in a flat state, and the flexible body 12 is also in a flat state. At this time, the first fixing member 16, the first heating member 16, the second heating member 18, and the slotting Both of 122a and 122b face upward (i.e., the opening direction of the slits 122a, 122b, or the orientation of the inner surface 12a). In addition, in the embodiment, the first fixing component 16 is exemplified by a plurality of fixed component parts 162, but a plurality of fixed component parts can still be logically arranged. 162 is considered as a whole and extends along the long axis direction 10; therefore, in practice, the first fixing member 16 can be a long strip member (for example, a long strip of devil felt) disposed along the long axis direction 10 On the three surface area 126, it will not be described. The foregoing also applies to the second fixing member 18, which will not be described again. It is to be noted that the first fixing member 16 and the second fixing member 18 both extend substantially in the longitudinal direction 10 to ensure a flexible flexible body along the longitudinal direction 10 . The body 12 can be evenly received by the fixing force of the first fixing element 16 and the second fixing element 18 to closely cover the tube bodies 2a, 2b, so that the first heating element 14 can effectively heat the tube bodies 2a, 2b; In this embodiment, the first heating element 14 contacts the tube bodies 2a, 2b, so the aforementioned fixing force also helps to reduce the thermal resistance between the first heating element 14 and the tube bodies 2a, 2b, thereby enhancing the pair of first heating elements 14 The heating rate of the tubes 2a, 2b.

Please refer to Fig. 2, which is a schematic cross-sectional view of the flexible heating device 1 wound tubular bodies 2a, 2b, the cross-sectional position of which is shown by the line X-X in Fig. 1. When the flexible heating device 1 is used, the tubes 2a, 2b are placed in the slots 122a, 122b, respectively, and then the flexible body 12 is bent and deformed, and the outer surface 12b abuts the third surface region 126 such that the first fixing member The second fixing member 18 and the second fixing member 18 are coupled to each other to maintain the flexible body 12 in a curled state to cover the tubular bodies 2a, 2b and to bring the first heating member 14 close to the tubular bodies 2a, 2b. In the present embodiment, the first heating element 14 directly contacts the tubular bodies 2a, 2b. After the coating is completed, the flexible heating device 1 can be powered up so that the first heating element 14 can heat the fluid within the tubes 2a, 2b. This fluid is not limited to blood, and other liquids such as physiological saline, drip or gas are suitable.

In addition, in the present embodiment, the second fixing component 18 is disposed on the outer surface 12b only corresponding to the second surface area 124, but the invention is not limited thereto. For example, in practice, the second fixing component 18 can be distributed over half. The outer surface 12b, and the flexible body 12 corresponding to the third surface area 126 can also be wound to the outer surface 12b of the corresponding first surface area 122, and the second fixing element 18 is coupled to the first fixing element 16 again. In principle, the fixing of the first fixing element 16 and the second fixing element 18 enables the tube bodies 2a, 2b to be fixed to In the slots 122a, 122b, and the first heating element 14 can effectively heat the tubes 2a, 2b, the present invention is not limited to the embodiment.

In the present embodiment, the pipe diameters of the pipe bodies 2a, 2b substantially match the cross-sectional profiles of the corresponding slots 122a, 122b, but in practice, due to the crimp deformation of the flexible body 12, the sections of the slots 122a, 122b The contour may be further reduced, so the pipe diameter of the pipe body 2a, 2b actually used may be smaller; similarly, since the flexible body 12 itself has elasticity, even if the pipe diameter of the pipe body 2a, 2b actually used is slightly larger than The cross-sectional profiles of the slots 122a, 122b, the slots 122a, 122b can still be deformed in conjunction with the tubular bodies 2a, 2b, while still maintaining the slots 122a, 122b substantially in contact with the tubular bodies 2a, 2b. Therefore, although the cross-sectional profiles of the slots 122a, 122b are fixed, the diameters of the tubes 2a, 2b to which the slots 122a, 122b are applicable are a range due to the flexibility of the flexible body 12, rather than the prior art. The medium blood heater can only be applied to a plurality of specific pipe diameters, so that the user does not need to over-deliberately compare the cross-sectional profiles of the pipe bodies 2a, 2b and the slots 122a, 122b. The user can visually judge the pipe body by visual inspection. Whether 2a, 2b substantially matches the slots 122a, 122b (i.e., falls within the foregoing range) saves operating time. In addition, the first fixing component 16 and the second fixing component 18 are not fixed in size, so that the user can easily adjust the relative bonding positions of the first fixing component 16 and the second fixing component 18 to achieve stability according to the pipe body actually used. The effect of coating the tube body will not be described again.

For convenience of explanation, the flexible heating device 3 still uses the component symbols of the flexible heating device 1, and the flexible heating device 3 has substantially the same structure as the flexible heating device 1, the main difference being that the flexible heating device 3 does not include the first heating. The element 14, but comprising two second heating elements 15a, 15b, are respectively disposed on the slots 122a, 122b and extend in a sheet shape along the major axis direction 10. Since the tubular bodies 2a, 2b are also placed on the slots 122a, 122b, when the flexible body 12 is kept in a curled state to cover the tubular bodies 2a, 2b, the second heating elements 15a, 15b contact the area of the tubular bodies 2a, 2b. Larger than the area of the first heating element 14 in the relatively flexible heating device 1 contacting the tubes 2a, 2b, this structural design helps to reduce the thermal resistance between the second heating elements 15a, 15b and the tubes 2a, 2b, thereby improving The heating rate of the tubes 2a, 2b. It should be noted that the foregoing descriptions of the selection and arrangement of the first heating element 14 are also applicable to the second heating elements 15a and 15b, and are not described herein. In addition, in practice, the slots 122a, 122b cover about half of the surface of the tubular bodies 2a, 2b, that is, in terms of the central angle of the section, the slots 122a, 122b cover the central angle of the tubular bodies 2a, 2b of about 180 degrees, but The invention is not limited thereto. For other descriptions of the flexible heating device 3, please refer to the related description of the flexible heating device 1 described above, and no further details are provided.

In addition, in the present embodiment, the heating heat sources of the flexible heating devices 1, 3 are mainly from the first heating element 14 or the second heating elements 15a, 15b, but the invention is not limited thereto. Please refer to FIG. 4, which is a cross-sectional view of the flexible tubular device 2a, 2b according to another embodiment. For convenience of explanation, the flexible heating device 4 still uses the component symbols of the flexible heating device 1. The flexible heating device 4 and the flexible heating device 1 have substantially the same structure, the main difference being that the flexible heating device 4 further includes two The two heating elements 15a, 15b are respectively disposed on the slots 122a, 122b and are in the form of a sheet along the long axis. 10 extensions. In other words, structurally, the flexible heating device 4 is a combination of the flexible heating device 1 and the flexible heating device 3. Therefore, in the flexible heating device 3, the tubes 2a, 2b placed in the slots 122a, 122b also contact the second heating elements 15a, 15b, respectively, which are designed to accelerate the heating rate of the tubes 2a, 2b. For the tubular bodies 2a, 2b, the first heating element 14 and the second heating elements 15a, 15b are located on opposite sides of the tubular bodies 2a, 2b to facilitate uniform heating. For other descriptions of the flexible heating device 4, please refer to the related description of the flexible heating devices 1, 3, and will not be described again.

Please refer to FIG. 5 and FIG. 6 , FIG. 5 is a schematic view of a flexible heating device 5 according to another embodiment, and FIG. 6 is a schematic cross-sectional view of the flexible heating device 5 winding the tubular bodies 2 a , 2 b . The position is as shown by the line YY in Fig. 5. For convenience of explanation, the flexible heating device 5 still uses the component symbols of the flexible heating device 1. The flexible heating device 5 and the flexible heating device 4 have substantially the same structure, the main difference being that the flexible body 52 of the flexible heating device 5 The first surface region 122 has a plurality of slits 122c, 122d, 122e, such as V-shaped grooves, extending along the major axis direction 10, wherein the slits 122d are disposed between the adjacent two slots 122a, 122b. The flexible body 52 has a thickness 52a that extends along a thickness direction 52b of the flexible body 52 by a depth 122f that is less than the thickness 52a. Since the slits 122c, 122d, and 122e provide a release space when the flexible body 52 is curled, when the flexible body 52 is curled, the slits 122c, 122d, and 122e are compressed and compressed, and the flexible heating device 5 can be effectively suppressed. The generation of surface wrinkles allows the slots 122a, 122b to maintain good adhesion to the tubular bodies 2a, 2b. It should be noted that, in this embodiment, the flexible body 52 can be divided into a plurality of connected blocks according to the slits 122c, 122d, and 122e. On the block The slots 122a, 122b have a cross-sectional profile that is different from each other. When the flexible body 52 remains in a curled state, the blocks are adjacently connected to form a plurality of tube channels of different tube diameters. For other descriptions of the flexible heating device 5, please refer to the related description of the flexible heating devices 1, 3, and 4, and no further description is provided.

In the foregoing embodiment, the first heating element 14 and the second heating element 15a, 15b are all illustrated as being directly attached to the inner surface 12a, but the invention is not limited thereto. Please refer to Fig. 7, which is a schematic cross-sectional view of the coiled tubes 2a, 2b of the flexible heating device 5a according to another embodiment. In the present embodiment, the flexible heating device 5a and the flexible heating device 5 have substantially the same structure, the main difference being that the first heating element 14 and the second heating elements 15a, 15b of the flexible heating device 5a are embedded in the flexible body. The inside of 52 is partially exposed to the inner surface 12a. In practice, the accommodating groove may be formed before the flexible body 52, and then the first heating element 14 and the second heating element 15a, 15b may be embedded; or when the burying process is used to form the flexible body 52, The first heating element 14 and the second heating elements 15a, 15b are embedded. This structural design helps to reduce the possibility of the user accidentally touching the heating element 14 and the second heating element 15a, 15b.

In addition, in the foregoing embodiment, the first heating element 14 and the second heating elements 15a, 15b are all described by directly contacting the tubular bodies 2a, 2b, but the invention is not limited thereto. Please refer to Fig. 8, which is a schematic cross-sectional view of the flexible tube 5a, 2b wound by the flexible heating device 5b according to another embodiment. In the present embodiment, the flexible heating device 5b is substantially identical in structure to the flexible heating device 5, the main difference being that the first heating element 14 and the second heating element 15a, 15b of the flexible heating device 5b are covered and protected. Layers 14a, 15c, 15d. The protective layers 14a, 15c, 15d provide an insulating function while protecting the user and the first heating element 14 and the second heating elements 15a, 15b themselves. In addition, in general, the protective layers 14a, 15c, 15d may interfere with heat conduction, but as long as the thickness of the protective layers 14a, 15c, 15d is thin enough, the corresponding thermal resistance can be suppressed to a certain value or less; The thickness is determined by the actual product requirements, which can be easily achieved by those skilled in the art, and will not be described again; and in FIG. 8, the thicknesses of the protective layers 14a, 15c, 15d are exaggerated. In addition, in practice, the protective layers 14a, 15c, 15d may be implemented by a film or a glue, but the invention is not limited thereto.

Please refer to FIG. 9 and FIG. 10, FIG. 9 is a schematic view of a flexible heating device 6 according to another embodiment, and FIG. 10 is a schematic cross-sectional view of the flexible heating device 6 winding the tubular bodies 2a, 2b. The position is as shown by the line ZZ in Fig. 9. For convenience of explanation, the flexible heating device 6 still uses the component symbols of the flexible heating device 1. The flexible heating device 6 differs from the flexible heating device 5 mainly in that the inner surface 62a of the flexible body 62 of the flexible heating device 6 The outer surface 124a of the second surface region further includes a fourth surface region 128 extending along the major axis direction 10, and the second fixing member 18 is disposed on the fourth surface region 128 adjacent to the outer side edge 124a of the second surface region. The upper heating element 14 and the second heating element 15a, 15b are located at the first fixing element 16 Between the second fixing element 18. Therefore, when the flexible body 62 remains in the curled state, the fourth surface area 128 abuts the third surface area 126 such that the first fixing element 16 and the second fixing element 18 can be coupled to each other, and the first heating element 14 also directly contacts the tube body. 2a, 2b.

As shown by the line WW in Fig. 11. For convenience of explanation, most of the components of the flexible heating device 7 still follow the symbol of the flexible heating device 1. The flexible heating device 7 and the flexible heating device 6 have substantially the same structure, the main difference being that the flexible heating device 7 is in the first A surface region 122 has a plurality of slots 722a, 722b, 722c and a plurality of slits 722d, 722e, 722f, 722g having the same cross-sectional profile. Similarly, the flexible body 72 can be divided into a plurality of connected blocks according to the slits 722d, 722e, 722f, and 722g. When the flexible body 72 is kept in a curled state, the blocks are adjacently connected. The single tube channel only accommodates a single tube 2c, so the first heating element 14 and the second heating element 75a, 75b, 75c of the flexible heating device 7 can effectively lie against the tube body 2c, which is beneficial to the heating efficiency of the tube body 2c. . For other descriptions of the flexible heating device 6, please refer to the related description of the flexible heating devices 1, 3, 4, 5, and 6, which will not be further described.

Please refer to Fig. 13, which is a schematic view showing the configuration of the flexible heating device 8 according to this embodiment. The flexible heating device 8 includes a flexible heating device body 80, a controller 82, a first temperature sensing element 84a, a second temperature sensing element 84b, and a third temperature sensing element 84c, wherein the flexible heating device body The structure of 80 may be the structure shown in any of the foregoing flexible heating devices 1, 3, 4, 5, 6, and 7, and thus with respect to the flexible heating device 80 For a detailed description, please refer to the related description of the flexible heating device 1, 3, 4, 5, 6, and 7, and no further details are provided. The controller 82 is electrically connected to the heating element (for example, the aforementioned elements 14, 15a, 15b, 75a, 75b, 75c) to control the heating of the heating element, and the controller 82 is also coupled to the first temperature sensing element 84a and the second temperature sensing element. 84b and the third temperature sensing element 84c are electrically connected to generate a warning signal according to the sensing result of each temperature sensing element 84a, 84b, 84c, the heating or triggering of the feedback control heating element is electrically connected to the controller 82. For example, sound, flash or electronic signals transmitted to other electronic receivers.

In the present embodiment, the flexible heating device body 80 includes a tubular body 2d. The flexible body of the flexible heating device body 80 defines an inlet end portion 802 and an outlet end portion 804 according to the flow direction 80a of the fluid in the tubular body 2d. For simplicity of explanation, the flow direction 80a is the same as the long axis direction 10. The first temperature sensing element 84a is disposed at the inlet end 802 and the second temperature sensing element 84b is disposed at the outlet end 804. In practice, the first temperature sensing element 84a and the second temperature sensing element 84b may be disposed on one of the slots such that when the flexible body of the flexible heating device body 80 remains in the curled state, the first temperature sensing element 84a And the second temperature sensing element 84b can contact the tube body so that the sensing result can reflect the temperature of the fluid in the tube body 2d as much as possible. Thereby, based on the sensing results of the first temperature sensing element 84a and the second temperature sensing element 84b, the controller 82 can more accurately control the heat and temperature rise of the fluid in the tubular body 2d. For example, the first temperature sensing element 84a can feed back the temperature of the controller 82 before the fluid is heated, the second temperature sensing element 84b can feed back the temperature of the controller 82 after the fluid is heated, and the controller 82 can control the input to the heating by the feedback information. The voltage or current of the component is used to generate the required amount of heat, so that the temperature of the fluid in the tube 2d can reach the desired temperature after heating.

In addition, the third temperature sensing element 84c is used to sense the temperature of a living body (such as a patient), and the sensing result of the third temperature sensing element 84c can be fed back to the controller 82 to control the heating of the heating element. For example, when the patient's body temperature is too high, the fluid in the tube 2d should not be overheated to avoid the patient's body temperature being difficult to fall; at this time, the controller 82 will also be the first temperature sensing element 84a and the first The feedback effect of the sensing result of the second temperature sensing element 84b controls the heating of the heating element. In addition, in practice, the first heating element and the second heating element can respectively control heating to increase the elasticity of the heating mechanism. In addition, in order to make the heating rate of the fluid uniform and stable, the resistance value of the heating element may vary along the long axis direction 10 (ie, the flow direction 80a), for example, the resistance value increases along the long axis direction 10; however, the present invention is not limited thereto. .

In addition, in the present embodiment, the sensing results of the temperature sensing elements 84a, 84b, and 84c can be used to issue an alarm to alert the operator (for example, medical staff, nursing care, family members) in addition to the heating control of the feedback controller 82. Wait). For example, when the controller 82 determines that one of the temperatures detected by the first temperature sensing element 84a is greater than a predetermined temperature (eg, standard body temperature), that is, the unheated fluid does not need to be reheated, and the temperature is too high. Even if it is no longer suitable for input into the patient, the controller 82 controls the warning component 86 to issue a warning signal. For another example, when the controller 82 determines that the temperature of one of the detections 84b via the second temperature sensing element is greater than a predetermined temperature (eg, standard body temperature), that is, the fluid has been overheated, it may not be suitable for input into the patient. The controller 82 controls the alert component 86 to emit an alert signal. For another example, when the controller 82 determines that one of the temperatures detected by the third temperature sensing element 84c is greater than a predetermined temperature (for example, the maximum allowable body temperature), the patient is already in a fever state, and the temperature of the liquid input into the body needs to be rigorous. Control, controller at this time 82 control alert component 86 issues an alert signal.
