Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of and priority to the following patent application: PCT patent application filed on August 6, 2021, with application number PCT / CN2021 / 111219. Technical Field

[0003] The present invention mainly relates to the field of medical devices, and in particular to a multi-layer adhesive tape analyte detection device. Background Art

[0004] In a healthy individual, the pancreas automatically monitors blood glucose levels and secretes the necessary insulin and glucagon. However, in diabetics, the pancreas malfunctions, preventing it from producing the necessary insulin. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function and is a lifelong condition. Currently, medical technology cannot cure diabetes; the only approach is to control the onset and progression of diabetes and its complications by stabilizing blood sugar levels.

[0005] Diabetics need to check their blood sugar before injecting insulin. Currently, most monitoring methods can continuously monitor blood sugar levels and transmit the data in real time to a remote device for easy viewing. This method is called continuous glucose monitoring (CGM). This method requires a monitoring device to be attached to the skin, and the sensor probe it carries penetrates the subcutaneous tissue fluid to complete the measurement.

[0006] After the detection device is attached to the user's skin surface, due to static electricity or skin movement, as the usage time increases, on the one hand, the adhesion of the adhesive material on the tape decreases, and on the other hand, the outer edge of the tape will warp, and the area of ​​the warped edge will increase, eventually causing the detection device to shift or fall off, affecting the normal use of the detection device.

[0007] Therefore, the prior art urgently needs an analyte detection device that can extend the use time of the adhesive tape. Summary of the Invention

[0027] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0028] In the multi-layer adhesive tape analyte detection device disclosed in the present invention, the analyte detection module is fixed to the user's skin surface by an adhesive module. The adhesive module includes N layers of adhesive tape. The first side of the first layer of adhesive tape is fixedly connected to the analyte detection module, and the second side opposite to the first side is coated with an adhesive material for adhering the analyte detection module to the user's skin surface.

[0032] Furthermore, the Rockwell hardness of the protective film is higher than that of the tape, and its outer edge contour is adapted to the outer edge contour of the tape, which can slow down the warping of the outer edge of the tape, extend the service life of the tape, and at the same time improve the appearance of the tape and enhance the user experience.

[0033] Furthermore, the protective film has a ring-shaped structure, which can avoid interference with the analyte detection module when pasted on the tape, while also improving the appearance of the tape and enhancing the user experience.

[0034] Furthermore, the protective film is provided with at least one tearing portion, such as a notch, a perforated tear line, or a disconnection seam, so as to reduce the impact on the inner layer of adhesive tape when the protective film is torn off.

[0049] As mentioned above, after the detection device of the prior art is pasted to the surface of the user's skin, due to static electricity, skin movement, weakening of the adhesive force of the adhesive material, etc., the outer edge of the tape on the detection device will warp during use. As the usage time increases, the area of ​​the warped edge increases, eventually causing the detection device to shift or fall off, affecting the normal use of the detection device and poor user experience.

[0050] In order to solve this problem, the present invention provides a multi-layer adhesive tape analyte detection device, in which the analyte detection module is fixed to the user's skin surface through an adhesive module, and N (N≥2) layers of adhesive tape are provided on the adhesive module. The first surface of the first layer of adhesive tape is fixedly connected to the analyte detection module, and the remaining adhesive tapes are sequentially stacked on the first surface of the first layer of adhesive tape. By relaying the inner and outer layers of adhesive tape, or delaying the edge warping of the inner layer of adhesive tape with the outer layer of adhesive tape, the service life of the adhesive module is extended, and the user experience is improved.

[0051] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments should not be construed as limiting the scope of the present invention.

[0052] In addition, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not necessarily drawn according to actual proportional relationships. For example, the thickness, width, length or distance of certain units may be enlarged relative to other structures.

[0053] The following description of exemplary embodiments is merely illustrative and is not intended to limit the present invention, its application, or use in any sense. Technologies, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but to the extent applicable, such technologies, methods, and apparatuses should be considered part of this specification.

[0054] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined or described in one figure, it will not need to be further discussed in the subsequent figure descriptions.

[0055] Figure 1a Schematic diagram of the three-dimensional structure of the multi-layer adhesive tape analyte detection device according to an embodiment of the present invention; Figure 1bThis is a schematic structural diagram of the multi-layer adhesive tape analyte detection device in another direction according to an embodiment of the present invention; Figure 2 Schematic diagram of the structure of the analyte detection module 100 according to an embodiment of the present invention; Figure 3 Schematic diagram of the structure of the pasting module 13 according to an embodiment of the present invention.

[0056] In an embodiment of the present invention, the analyte detection device includes an analyte detection module 100 and an adhesive module 13. The analyte detection module 100 includes a bottom shell 10, a transmitter unit 12, a sensor unit 11 and a battery (not shown in the figure). The bottom shell 10 is used to assemble the transmitter unit 12 and the sensor unit 11. The sensor unit 11 includes an external part 1131 and an internal part 1132. The internal part 1132 is bent relative to the external part 1131.

[0057] In an embodiment of the present invention, the pasting module 13 includes a first layer of adhesive tape 131, the first surface (outer surface) of the first layer of adhesive tape 131 is fixedly connected to the bottom shell 10, and the second surface (inner surface) is coated with an adhesive material for pasting the analyte detection device on the user's skin surface.

[0058] In an embodiment of the present invention, the first layer of adhesive tape 131 is made of one of polyethylene, polypropylene, non-woven fabric or pure cotton, and the second side of the first layer of adhesive tape 131 is in direct contact with the user's skin. According to the actual use environment, the selection of the above materials can avoid adverse reactions caused by long-term contact of the first layer of adhesive tape 131 with the skin.

[0059] In order to adapt to the movement of the user's skin, such as bending and stretching, the thickness of the first layer of adhesive tape 131 is very thin, for example, about 1 to 500 um. Such a thin adhesive tape will cause other problems, such as static electricity on the user's skin, or violent movement of the skin, which will cause the outer edge of the adhesive tape to warp. Once the outer edge of the adhesive tape warps, the area of ​​the warped edge of the first layer of adhesive tape 131 will gradually increase with the increase in usage time, resulting in a decrease in the adhesive force between the first layer of adhesive tape 131 and the skin, which may cause the analyte detection device to shift or fall off. In addition, during use, the viscosity of the adhesive material decreases, which may also cause the analyte detection device to shift or fall off, affecting the user experience.

[0060] In an embodiment of the present invention, a protective film 132 is added to the outer edge of the first surface of the first layer of tape 131. The Rockwell hardness of the protective film 132 is greater than that of the first layer of tape 131. In a preferred embodiment of the present invention, the Rockwell hardness of the protective film 132 is 80-100 HRM.

[0061] In a preferred embodiment of the present invention, the protective film 132 is made of one of polycarbonate, polyamide, polyoxymethylene, polyphenylene ether, polyester, polyphenylene sulfide, and polyarylate.

[0062] In a more preferred embodiment of the present invention, the protective film 132 is made of polyethylene terephthalate (PET) with a Rockwell hardness of 90-95 HRM.

[0063] In an embodiment of the present invention, the outer edge contour of the protective film 132 is adapted to the outer edge contour of the first layer of tape 131. Here, "adapted" means that the outer edge contour size, bending radius, shape and other parameters of the protective film 132 are consistent with the outer edge contour parameters of the first layer of tape 131, so that every part of the outer edge of the first layer of tape 131 can be fitted with the protective film 132.

[0064] In the embodiment of the present invention, the thickness of the protective film is 10-500 um.

[0065] In this embodiment of the present invention, protective film 132 is annular. The hollow structure of the annular structure allows the protective film to adhere to the outer surface of the first layer of adhesive tape 131 without interfering with the analyte detection module 100. Furthermore, the inner and outer edges of the annular protective film are consistent, which improves the appearance and enhances the user experience.

[0066] In the embodiment of the present invention, a first through hole 1311 is formed on the first layer of adhesive tape 131 . The position of the first through hole 1311 corresponds to the inner portion 1132 of the sensor body, so as to allow the inner portion 1132 of the sensor body to pass through and penetrate the user's skin.

[0067] In the embodiment of the present invention, at least one layer of release paper 133 is provided on the inner surface of the first layer of adhesive tape 131. The release paper 133 can prevent the adhesive material on the inner surface of the first layer of adhesive tape 131 from sticking together and protect the adhesive material from contamination.

[0068] In a preferred embodiment of the present invention, the release paper 133 is a single silicon release paper, and its peeling force is 30-50 g.

[0069] In the embodiment of the present invention, a second through hole 1331 is opened on the release paper 133, and the position of the second through hole 1331 corresponds to the first through hole 1311, so that the inner part 1132 of the sensor body can pass through the first through hole 1311 and the second through hole 1331 in sequence to penetrate the user's skin.

[0070] Figure 4a This is a schematic structural diagram of each layer of the pasting module 13 according to an embodiment of the present invention; Figure 4b This is a schematic diagram of the stacking sequence of the pasting module 13 according to one embodiment of the present invention; Figure 4c This is a structural diagram of each layer of the pasting module 13 according to another embodiment of the present invention; Figure 4d This is a schematic diagram of the stacking sequence of the pasting module 13 according to another embodiment of the present invention; Figure 4e Schematic diagram of the stacking of inner and outer layers of adhesive tape according to another embodiment of the present invention.

[0071] In this embodiment of the present invention, to facilitate the user's peeling of the release paper 133 from the first layer of adhesive tape 131 and to save space, the release paper 133 is preferably comprised of two layers, with the peeling openings facing inward. The peeling opening of one layer is bent outward and covered by the peeling opening of the other layer. In conjunction with the foregoing, the adhesive module 13 comprises, from the outer layer to the inner layer, the protective film 132, the first layer of adhesive tape 131, and the release paper 133.

[0072] In the embodiment of the present invention, to further extend the service life of the adhesive module 13, a second layer of adhesive tape 134 is provided on the outer surface of the first layer of adhesive tape 131. The second layer of adhesive tape 134 is annular to avoid interference with the analyte detection module 100.

[0073] In an embodiment of the present invention, the edge profile of the second layer of adhesive tape 134 conforms to the outer edge profile of the first layer of adhesive tape 131. "Conform" here means that the shape of the second layer of adhesive tape 134 is consistent with that of the first layer of adhesive tape 131, but its outer dimensions and bending radius can be modified according to actual needs. For example, in some embodiments, the outer edge of the second layer of adhesive tape 134 protrudes beyond the outer edge of the first layer of adhesive tape 131. After the adhesive module 13 has been used for a period of time, the outer edge of the second layer of adhesive tape 134 may warp. In this case, the second layer of adhesive tape 134 can be removed, revealing the first layer of adhesive tape 131, which has not warped. This allows the adhesive module 13 to continue to function normally, while the first layer of adhesive tape 131 remains clean and tidy, maintaining the hygiene and aesthetics of the adhesive module 13 and improving the user experience. For another example, in some embodiments, the outer edge of the second layer of adhesive tape 134 overlaps the outer edge of the first layer of adhesive tape 131. The second layer of adhesive tape 134 can enhance the Rockwell hardness of the first layer of adhesive tape 131 and mitigate the warping of the outer edge of the first layer of adhesive tape 131. For another example, in some embodiments, the outer edge of the second layer of adhesive tape 134 is located inwardly of the outer edge of the first layer of adhesive tape 131. When the outer edge of the first layer of adhesive tape 131 warps, the second layer of adhesive tape 134 located further inwardly can slow down the warping, thereby extending the service life of the adhesive module 13. For another example, the outer edge of one side of the second layer of adhesive tape 134 protrudes from the outer edge of the first layer of adhesive tape 131, while the outer edge of the other side is located inwardly of the outer edge of the first layer of adhesive tape 131, forming a staggered arrangement.

[0074] In a preferred embodiment of the present invention, a protective film 132 is provided between the second layer of adhesive tape 134 and the first layer of adhesive tape 131. Specifically, the protective film 132 is located on the contact surface between the second layer of adhesive tape 134 and the first layer of adhesive tape 131. The protective film 132 can reduce the impact on the first layer of adhesive tape 131 when the second layer of adhesive tape 134 is removed, ensuring that the first layer of adhesive tape 131 remains in full contact with the skin surface.

[0075] In another preferred embodiment of the present invention, to facilitate tearing off the protective film 132 from the surface of the first layer of adhesive tape 131, a tearing portion 1321 is provided on the protective film 132. The user can break or tear off the protective film 132 at the tearing portion 1321, which can minimize the impact on the inner layer of adhesive tape when tearing off the protective film 132.

[0076] In the embodiment of the present invention, the number of the tearing portion 1321 can be one or more.

[0077] In the embodiment of the present invention, the tear portion 1321 may be a notch, a perforated tear line, or a disconnection seam. Those skilled in the art will appreciate that the present invention does not limit the specific structure of the tear portion 1321 as long as it is convenient for the user to tear or break the protective film 132.

[0078] In an embodiment of the present invention, a third layer of tape 136 may be further provided on the outer surface of the second layer of tape 134. The effect of the third layer of tape 136 on the second layer of tape 134 is the same as the effect of the second layer of tape 134 on the first layer of tape 131, and will not be repeated here.

[0079] In the embodiment of the present invention, a second layer of protective film 135 is further provided between the second layer of adhesive tape 134 and the third layer of adhesive tape 136 . The function of the second layer of protective film 135 is the same as that of the protective film 132 and will not be described in detail herein.

[0080] In this embodiment of the present invention, the adhesive tape in the adhesive module 13 is not limited to three layers; it can also be more layers. The second to Nth (N≥2) layers of adhesive tape are stacked layer by layer on the outer surface of the first layer of adhesive tape 131. Except for the first layer of adhesive tape 131, the remaining adhesive tapes and protective films are all ring-shaped to prevent interference with the analyte detection module 100.

[0081] In an embodiment of the present invention, one or more protective films are provided between two adjacent layers of adhesive tape to reduce the impact on the inner layer of adhesive tape when the outer layer of adhesive tape is torn off.

[0082] In other embodiments of the present invention, one or more protective films are provided every two layers of adhesive tape, or one or more protective films are provided every three layers of adhesive tape, and there is no particular limitation here.

[0083] In an embodiment of the present invention, the positional relationship of the outer layer of tape relative to the inner layer of tape is consistent with the positional relationship of the second layer of tape 134 relative to the first layer of tape 131. The outer layer of tape can completely cover the adjacent inner layer of tape or partially cover the adjacent inner layer of tape.

[0084] In the embodiment of the present invention, at least one tearing portion may be provided on the second layer of adhesive tape 134 to the Nth layer of adhesive tape to facilitate the user to tear off the adhesive tape. The structure of the tearing portion is as described above and will not be repeated here.

[0085] Continue to refer Figure 1a 、 Figure 1b and Figure 2 The bottom shell 10 includes a fixing portion and a force-applying portion. At least one second engaging portion 101 is provided on the bottom shell 10. The second engaging portion 101 is used to engage the transmitter unit 12. Specifically, in this embodiment of the present invention, there are two second engaging portions 101. The two second engaging portions 101 are correspondingly provided on the side walls of the bottom shell 10.

[0086] Here, the fixing portion and the force-applying portion are relative concepts. Depending on the structural design of the bottom housing 10 and the transmitter unit 12, the positions of the fixing portion and the force-applying portion can be selected in different ways, which will be described in detail below.

[0087] The transmitter unit 12 is used to receive the detection signal generated by the sensor and wirelessly transmit the signal to a remote device. Therefore, the transmitter unit 12 is connected to the sensor.

[0088] The transmitter unit 12 is provided with at least one first engaging portion 121. The first engaging portion 121 corresponds to the second engaging portion 101. The second engaging portion 101 and the first engaging portion 121 engage with each other, allowing the transmitter unit 12 to be assembled to the bottom housing 10. Obviously, in this embodiment of the present invention, the transmitter unit 12 is provided with two first engaging portions 121, i.e., two pairs of mutually engaging first engaging portions 121 and second engaging portions 101.

[0089] Here, the first engaging portion 121 corresponds to the second engaging portion 101 , which means that the number of the first engaging portion 121 and the second engaging portion 101 are equal and the positions of the first engaging portion 121 and the second engaging portion 101 correspond to each other.

[0090] When separating the bottom case 10 from the transmitter unit 12, the fixing portion is held in place by a finger or other device. Using another finger or other auxiliary device, force is applied to the force-applying portion in one direction. This deactivates the bottom case 10, causing the second engaging portion 101 and the first engaging portion 121 to separate, thereby separating the transmitter unit 12 from the bottom case 10. This allows the user to separate the bottom case 10 from the transmitter unit 12 by simply applying force in one direction to the force-applying portion with a single finger, making the process easier for the user. After separation, the transmitter can be reused, reducing costs for the user.

[0091] It should be noted that failure is a common concept in the field of engineering materials. After failure, the material loses its original function and the failed part cannot be restored. Since the second engaging portion 101 is a part of the bottom shell 10, the failure of the bottom shell 10 includes the failure of the bottom plate, side wall or second engaging portion 101 of the bottom shell 10. Therefore, the failure mode of the bottom shell 10 includes the fracture of the bottom plate or side wall of the bottom shell 10 (such as Figure 6b As shown), the bottom shell 10 is broken, and the second engaging portion 101 is broken (as shown Figure 6d As shown), one or more forms of plastic deformation of the bottom shell 10. Obviously, after the bottom shell 10 fails, the bottom shell 10 loses the function and role of locking the transmitter unit 12.

[0092] Ways to fix the fixing portion include clamping, supporting, etc., which are not specifically limited here, as long as the conditions for fixing the fixing portion are met.

[0093] Specifically, in the embodiment of the present invention, the line 11 connecting the two second engaging portions 101 divides the bottom housing 10 into side A and side B. Side A is provided with a force-applying portion, and side B is provided with a fixing portion.

[0094] Therefore, in the embodiment of the present invention, the process of separating the bottom shell 10 and the transmitter unit 12 is as follows: fix the fixing portion on the B side with one finger, and use another finger to apply a force F to the force-applying portion in one direction, so that the second engaging portion 101 becomes ineffective, and then the second engaging portion 101 and the first engaging portion 121 are separated, so that the transmitter unit 12 is separated from the bottom shell 10.

[0095] It should be noted that the embodiment of the present invention does not limit the position of the second engaging portion 101 . For example, the two second engaging portions 101 may be disposed on the bottom plate of the bottom shell 10 . No specific limitation is made here.

[0096] The embodiment of the present invention does not impose any specific limitation on the shape of the top view of the detection device, and the shape may also be a rounded rectangle, a rectangle, a circle, an ellipse or other shapes.

[0097] The detection device of this embodiment of the present invention also includes a battery (not shown). The battery is used to power the transmitter and is located within the bottom housing 10. The battery is located within the bottom housing 10 as a battery portion 123. Preferably, in this embodiment of the present invention, the top of the battery portion 123 is flush with the top of the transmitter unit 12, thereby reducing the thickness of the detection device.

[0098] The battery portion 123 can directly serve as the force application portion, and is therefore located on the A side of the I1. Since the battery portion 123 is thicker and has a relatively larger area, it is easier for the user to apply force to the battery portion, thus optimizing the user's operation steps.

[0099] Figure 5FIG. 1 is a top view of the bottom case 10 according to an embodiment of the present invention.

[0100] Since the battery needs to supply power to the transmitter unit 12, in this embodiment of the present invention, the bottom case 10 is further provided with at least one connection hole 104. Through the connection hole 104, the transmitter unit 12 is electrically connected to the positive and negative electrodes of the battery respectively.

[0101] The connection hole 104 may be provided with an electrical contact capable of electrically connecting to the transmitter unit 12. Alternatively, the transmitter unit 12 may be provided with a protruding electrical connection terminal that can be inserted into the connection hole 104. Alternatively, the battery and the transmitter unit 12 may be electrically connected via a wire passing through the connection hole 104 or a conductive lead plated on the surface of the bottom housing 10.

[0102] It should be noted that other embodiments of the present invention may not have the connection hole 104 , and the transmitter unit 12 and the two poles of the battery are electrically connected through conductive leads completely plated on the surface of the bottom shell 10 , which is not specifically limited here.

[0103] Preferably, in the embodiment of the present invention, a sealing ring 105 is provided around the connection hole 104 in order to seal the electrical connection position.

[0104] Generally, elastic sealing materials act as sealants when squeezed. In this embodiment of the present invention, the squeezed sealing ring 105 exerts a certain elastic force on the transmitter unit 12. When the force F is applied to the force-applying portion, the sealing ring 105 provides an elastic force that facilitates the separation of the transmitter unit 12 from the bottom housing 10.

[0105] Preferably, in this embodiment of the present invention, a seal (not shown) is provided around the sensor to seal the connection between the transmitter unit 12 and the sensor. Similar to the aforementioned sealing ring 105, when the force F is applied to the force-applying portion, the seal also provides an elastic force that facilitates the separation of the transmitter unit 12 from the bottom housing 10.

[0106] It should be noted that, since the sealing performance of the electrical connection position between the transmitter unit 12 and the battery or the connection position between the transmitter unit 12 and the sensor is relatively good, other embodiments of the present invention may not include the sealing ring 105 or the sealing member.

[0107] In this embodiment of the present invention, a crease 102 is further provided on the bottom case 10 at a position corresponding to the line 11. This crease 102 can reduce the thickness of the bottom case, making it easier for the bottom case 10 to be broken along the crease 102 and simplifying the separation operation. Obviously, the crease 102 can extend through the bottom plate of the bottom case 10 along the line 11.

[0108] Preferably, in the embodiment of the present invention, the bottom plate of the bottom housing 10 is further provided with a mounting hole 106 and a sensor unit 11 disposed in the mounting hole 106. The outer edge profile of the sensor unit 11 matches the outer edge profile of the mounting hole 106. Here, matching the outer edge profiles of the two means that the outer edges of the two can fit into each other.

[0109] The external portion 1131 of sensor 113 is mounted on sensor unit 11, while the internal portion 1132 extends subcutaneously. During installation, sensor 113 is supported by sensor unit 11 and mounted on bottom case 10. Preferably, in this embodiment of the present invention, the configuration of sensor 113 on sensor unit 11 remains unchanged before and after installation; that is, sensor 113 and sensor unit 11 are simultaneously mounted on bottom case 10. Therefore, after sensor 113 is installed, sensor unit 11 becomes part of bottom case 10.

[0110] It should be noted that, in other embodiments of the present invention, the detection device can be directly mounted on the skin surface as a whole without using the sensor unit 11 to carry the sensor 113, and no specific limitation is made here.

[0111] Figure 6a and Figure 6b They are schematic structural diagrams of the side wall or bottom plate of the bottom shell 10 before and after failure. Figure 6c and Figure 6d They are schematic structural diagrams of the second engaging portion 101 of the bottom shell 10 before and after failure.

[0112] As mentioned above, the first engaging portion 121 and the second engaging portion 101 are hooks. When a force F is applied to the force applying portion in one direction, the bottom shell 10 is broken along the fold groove 102, as shown by the dotted circle C. Figure 6c-6d When a force F is applied to the force applying portion in one direction, the second engaging portion 101 is broken.

[0113] In other embodiments of the present invention, the first engaging portion 121 and the second engaging portion 101 may be a engaging hole and a engaging block, or a engaging block and a engaging slot, etc., respectively, and are not specifically limited here.

[0114] In other embodiments of the present invention, the transmitter unit 12 may also be a force-applying portion, which is not specifically limited here. It should be noted that although the force F may act directly on the transmitter unit 12, the actual effect of the force F is only manifested on the bottom shell 10. That is, the force F only changes the form of the bottom shell 10 (such as the shape and structure), and does not change the form of the transmitter unit 12. In this case, it can still be considered that the user is applying a force to the force-applying portion of the bottom shell 10.

[0115] In summary, the present invention discloses a multi-layer adhesive tape analyte detection device, in which the analyte detection module is fixed on the user's skin surface through an adhesive module, and N (N≥2) layers of adhesive tape are provided on the adhesive module. The first side of the first layer of adhesive tape is fixedly connected to the analyte detection module, and the remaining adhesive tapes are sequentially stacked on the first side of the first layer of adhesive tape. By relaying the adhesive tapes, or by delaying the edge warping of the inner layer of adhesive tape by the outer layer of adhesive tape, the service life of the adhesive module is extended, and the user experience is improved.

It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
