CGM meters are medical devices that continuously monitor a patient's blood glucose. They are typically worn by the user using medical tape. In existing technology, one side of the medical tape is adhered to the CGM meter, and the other side is attached to the user's skin. However, this medical tape has poor stability and breathability. During wear, the CGM meter often accidentally falls off due to excessive sweating, accidental impacts, or the tape tearing, forcing an interruption of blood glucose monitoring. Utility Model Content
[0003] The purpose of this utility model is to provide a medical fixing tape for dynamic blood glucose meters, so as to solve to a certain extent the technical problems of poor stability and poor breathability of existing medical tapes, which often cause the dynamic blood glucose meter to fall off accidentally due to excessive sweating, accidental collisions, or tape tearing during wear, thus forcing the interruption of blood glucose monitoring.
[0004] This utility model provides a medical fixing tape for a dynamic blood glucose meter, comprising: a protective layer, an adhesive layer, a release film, and a fixing bracket; the protective layer includes a first edge, a second edge, a third edge, and a fourth edge connected end to end, and the outline formed by the first edge, the second edge, the third edge, and the fourth edge is rhomboid, and the protective layer has multiple micropores; the adhesive layer is applied to one side of the protective layer, and the release film is applied to the side of the adhesive layer away from the protective layer; the fixing bracket includes multiple bottom fixing strips and multiple side fixing strips; the multiple bottom fixing strips are arranged crosswise, and each bottom fixing strip is connected to two ends by a side fixing strip, the end of the side fixing strip away from the bottom fixing strip is fixed to the edge of the mounting hole, the side fixing strip extends along the opening direction of the mounting hole so that the bottom fixing strip extends out of the protective layer away from the adhesive layer, and a mounting cavity is formed between the side fixing strip and the bottom fixing strip, the mounting cavity being used to install the dynamic blood glucose meter.
[0005] Furthermore, a first corner is formed between the first edge and the second edge, and between the third edge and the fourth edge; a second corner is formed between the second edge and the third edge, and between the fourth edge and the first edge; the angle of the first corner is 115°-125°, and the angle of the second corner is 55°-75°.
[0006] Furthermore, the angle of the first corner is 120°, and the angle of the second corner is 60°.
[0007] Furthermore, the diameter of the micropores is 0.75nm-0.85nm; the spacing between the micropores is 1.5nm-3.5nm.
[0008] Furthermore, the number of bottom fixing strips is two, and the number of side fixing strips is four.
[0009] Furthermore, the dynamic blood glucose meter medical fixing tape also includes a protective net, the edge of which is fixed around the mounting hole, and the protective net wraps around the side of the fixing bracket away from the adhesive layer.
[0010] Furthermore, the dynamic blood glucose meter medical fixing tape also includes a reinforcing strip, which is arranged in a ring around the mounting hole.
[0011] Furthermore, the dynamic blood glucose meter medical fixing tape also includes traction strips. Along the length of the protective layer, traction strips are fixed at both ends of the release film. The two traction strips are located at the two corners and extend out of the protective layer. A break is provided in the middle of the release film.
[0012] Furthermore, the dynamic blood glucose meter medical fixing tape also includes two straps, both of which are connected to the protective layer. The two straps extend from both ends of the protective layer along its length, and the free ends of the two straps can be connected to each other.
[0013] Furthermore, the strap includes a binding part and an adhesive part, the binding part is integrally formed with the protective layer, one strap has an adhesive part on its outer side, and the other strap has an adhesive part on its inner side, and the two adhesive parts can be bonded to each other.
[0014] Compared with the prior art, the main advantages of this utility model are:
[0015] When using the medical fixing tape for the dynamic blood glucose meter provided by this utility model, the release film can be peeled off to expose the adhesive layer. The dynamic blood glucose meter can then be installed into the mounting cavity of the fixing bracket through the mounting hole on the side of the adhesive layer (the dynamic blood glucose meter can be installed on the fixing bracket first, and then the release film can be peeled off). The adhesive layer can then be attached to the user's body to fix the dynamic blood glucose meter to the user's body. The protective layer in this invention is rhomboid in shape, meaning the overall shape of the dynamic blood glucose meter's medical fixing tape is rhomboid. This rhomboid shape prevents the tape from easily detaching under pressure, while ensuring sufficient length without a large overall area, thus improving user comfort. The dynamic blood glucose meter's medical fixing tape has a double-layer structure: an outer protective layer and an inner adhesive layer. The adhesive layer serves as the adhesive, while the protective layer prevents intrusion. The protective layer has micropores to maintain a certain degree of breathability, improving user comfort, and also provides waterproofing, preventing external moisture or liquids from seeping in, making it suitable for use in humid environments. The side fixing strips of the fixing bracket restrain the sides of the dynamic blood glucose meter, and the bottom fixing strip restrains the bottom, effectively securing the meter. After the adhesive layer is applied to the user's skin, it prevents the dynamic blood glucose meter from detaching from the mounting holes, further improving the stability of the dynamic blood glucose meter.

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0025] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.
[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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 utility model.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0030] like Figures 1 to 4 As shown, this utility model provides a medical fixing tape for a dynamic blood glucose meter, comprising: a protective layer 1, an adhesive layer, a release film, and a fixing bracket 3; the protective layer 1 includes a first edge, a second edge, a third edge, and a fourth edge connected end to end, and the outline formed by the first edge, the second edge, the third edge, and the fourth edge is rhomboid; the protective layer 1 has a plurality of micropores 11 (micropores 11 refer to pores with a diameter of less than 2nm); the adhesive layer is applied to one side of the protective layer 1, and the release film is applied to the side of the adhesive layer away from the protective layer 1; the fixing bracket 3... The frame 3 includes multiple bottom fixing strips 31 and multiple side fixing strips 32; the multiple bottom fixing strips 31 are arranged crosswise, and each bottom fixing strip 31 is connected to both ends of a side fixing strip 32. The end of the side fixing strip 32 away from the bottom fixing strip 31 is fixed to the edge of the mounting hole 4. The side fixing strip 32 extends along the opening direction of the mounting hole 4 so that the bottom fixing strip 31 extends out of the protective layer 1 away from the adhesive layer. An installation cavity is formed between the side fixing strip 32 and the bottom fixing strip 31. The installation cavity is used to install the dynamic blood glucose meter.
[0031] When using the medical fixation tape for the continuous glucose meter provided in this embodiment, the release film can be peeled off to expose the adhesive layer. The continuous glucose meter can then be installed into the mounting cavity of the fixation bracket 3 through the mounting hole 4 on the side of the adhesive layer (the continuous glucose meter can be installed on the fixation bracket 3 first, and then the release film can be peeled off). The adhesive layer can then be attached to the user's body to fix the continuous glucose meter to the user's body. In this embodiment, the protective layer 1 is rhomboid in shape, meaning the general shape of the dynamic blood glucose meter's medical fixing tape is rhomboid. This rhomboid shape prevents the tape from easily detaching under pressure, while ensuring sufficient length and avoiding a large overall area, thus improving user comfort. The dynamic blood glucose meter's medical fixing tape has a double-layer structure: an outer protective layer 1 and an inner adhesive layer. The adhesive layer serves as the adhesive, while the protective layer 1 prevents intrusion. The protective layer 1 has micropores 11 to maintain a certain degree of breathability, improving user comfort and providing waterproofing to prevent external moisture or liquid penetration, making it suitable for use in humid environments. The side fixing strip 32 of the fixing bracket 3 restricts the sides of the dynamic blood glucose meter, and the bottom fixing strip 31 restricts the bottom, effectively securing the meter. After the adhesive layer is applied to the user's skin, it prevents the dynamic blood glucose meter from detaching from the mounting hole 4, further improving the stability of the dynamic blood glucose meter.
[0032] Optionally, the protective layer 1 can be made of polymer materials, such as polyethylene (PE) or polyurethane (PU). The polymer materials can contain silver ions to achieve antibacterial effects and thus maintain the antibacterial state of the adhesive tape surface.
[0033] Understandably, the release film can be split in half, meaning there is a break in the middle of the release film to make it easy to peel off.
[0034] The protective layer 1 preferably uses medical-grade acrylic adhesive to ensure a firm bond while minimizing skin irritation and damage.
[0035] A coating technique can be used to evenly coat the adhesive layer onto the inner side of the protective layer 1, and the adhesive layer can be cured by controlling the temperature and humidity conditions to ensure its stability and durability.
[0036] The side fixing strip 32 is preferably integrally formed with the bottom fixing strip 31. The side fixing strip 32 can be fixed to the protective layer 1 by means of bonding, hot pressing or welding (such as ultrasonic spot welding).
[0037] The shape of mounting hole 4 can be circular or quadrilateral, etc.
[0038] like Figure 1 As shown, based on the above embodiment, a first corner 12 is formed between the first and second edges and between the third and fourth edges, and a second corner 13 is formed between the second and third edges and between the fourth edge and the first edge. The angle of the first corner 12 is 115°-125° (e.g., 115°, 118°, 120°, 123° or 125°, etc.), and the angle of the second corner 13 is 55°-75° (e.g., 55°, 57°, 60°, 62° or 75°, etc.). Preferably, the angle of the first corner 12 is 120° and the angle of the second corner 13 is 60°. The angle of the first corner 12 being 120° can better maintain stability and is less likely to fall off when subjected to force. The angle of the second corner 13 being 60° can achieve a better aspect ratio, further ensuring sufficient length so that the area is not too large, and further improving the comfort of the skin surface.
[0039] like Figure 4As shown, based on the above embodiments, the diameter of the micropores 11 is further 0.75nm-0.85nm (0.75nm, 0.77nm, 0.80nm, 0.82nm or 0.85nm, etc.); the pore spacing of the micropores 11 is 1.5nm-3.5nm (1.5nm, 2.0nm, 2.5nm, 3nm or 3.5nm, etc.). The normal pore spacing of adults is 2-3nm, and the pore diameter is 0.3-0.6nm. By selecting a pore diameter in the range of 0.75nm-0.85nm and a pore spacing in the range of 1.5nm-3.5nm, it is possible to ensure good breathability, avoid skin allergies or infections caused by prolonged closure, and improve waterproofness, further ensuring that external moisture or liquids cannot penetrate.
[0040] The pore diameters of the multiple micropores 11 may be different, or some of the micropores 11 may have the same pore diameter. Optionally, the pore diameters of the multiple micropores 11 may all be the same, which facilitates processing.
[0041] In the multiple micropores 11, the spacing between the pores can be equal, or the spacing between some micropores 11 can be the same as the first pore spacing, and the spacing between some micropores 11 can be the same as the second pore spacing. The first pore spacing and the second pore spacing can be different. For example, there are pore spacings of 3nm and pore spacings of 1.5nm. This setting can make the density of micropores 11 in different parts of the protective layer 1 different, which can be set as needed, thereby making the user's skin surface more comfortable.
[0042] like Figure 1 As shown, based on the above embodiments, the number of bottom fixing strips 31 can be three, four, or five, and correspondingly, the number of side fixing strips 32 can be six, eight, or ten.
[0043] The bottom fixing strip 31 and the side fixing strip 32 are made of the same material, such as rubber or silicone.
[0044] As an alternative, such as Figure 1 As shown, there are two bottom fixing strips 31 and four side fixing strips 32. This ensures both the limiting and protection of the continuous glucose meter and avoids the complexity and high cost of manufacturing caused by setting too many bottom fixing strips 31 and side fixing strips 32.
[0045] like Figure 2As shown, based on the above embodiment, the continuous glucose meter medical fixing tape further includes a protective net 5. The edge of the protective net 5 is fixed around the mounting hole 4, and the protective net 5 wraps around the side of the fixing bracket 3 away from the adhesive layer. Providing the protective net 5 on the outside of the fixing bracket 3 can further protect the continuous glucose meter and further improve the stability of the continuous glucose meter fixed to the user.
[0046] Optionally, the protective netting 5 can be made of woven thread.
[0047] like Figure 1 As shown, based on the above embodiments, the dynamic blood glucose meter medical fixing tape further includes a reinforcing strip 6 (which can be made of the same material as the protective layer 1, or a flexible material different from the protective layer 1). The reinforcing strip 6 is arranged in a ring around the mounting hole 4, thereby reinforcing the periphery of the mounting hole 4, enhancing the durability and tear resistance of the edge of the mounting hole 4, effectively preventing edge damage caused by pulling or friction during use, and extending the service life of the tape.
[0048] The reinforcing strip can be fixed around the mounting hole 4 by bonding, hot pressing, or welding (e.g., ultrasonic spot welding).
[0049] like Figures 1 to 3 As shown, based on the above embodiments, the dynamic blood glucose meter medical fixing tape further includes traction strips 7. Traction strips 7 are fixed at both ends of the release film along the length of the protective layer 1. The two traction strips 7 are located at two corners and extend out of the protective layer 1. A break is provided in the middle of the release film.
[0050] In this embodiment, a break is provided in the middle of the release film along the length of the protective layer 1. Each release film segment is fixed with a traction strip 7 at one end, and the traction strip 7 extends out of the protective layer 1. When in use, the user can pull the traction strip 7 to tear off the two release films, which is convenient for the user.
[0051] The traction strip 7 can be integrally molded with the release film, and a reinforcing sheet can be laminated on the traction strip 7 to ensure the rigidity of the traction strip 7 and make it more convenient to use.
[0052] like Figures 1 to 3 As shown, based on the above embodiments, the dynamic blood glucose meter medical fixing tape further includes two straps 8, both straps 8 are connected to the protective layer 1, and the two straps 8 extend from both ends of the protective layer 1 in the length direction of the protective layer 1, and the free ends of the two straps 8 can be connected to each other.
[0053] In this embodiment, the straps 8 are provided so that when it is necessary to fix the continuous glucose monitoring device (CGM) to the arm or leg, two straps 8 can be wrapped around the arm or leg and connected to each other, thereby further improving the stability of the CGM on the body. If the user needs to fix the CGM to a part of the body, the user can selectively cut off the straps 8.
[0054] The strap 8 can be an elastic band, with a buckle on one elastic band and multiple eyelets spaced apart on the other elastic band; alternatively, the strap 8 can be a flat strap, with a hook and loop side of hook and loop fastener on one flat strap and a hook and loop side of hook and loop fastener on the other flat strap, and the two flat straps are fixed together by hook and loop fastener. When the material of the strap 8 is different from that of the protective layer 1, the strap 8 and the protective layer 1 can be connected by heat pressing or welding.
[0055] As an alternative, such as Figure 3 As shown, the strap 8 includes a binding part 81 and an adhesive part 82. The binding part 81 is integrally formed with the protective layer 1. One strap 8 has an adhesive part 82 on its outer side (the material of the adhesive part 82 can be the same as the material of the adhesive layer), and the other strap 8 has an adhesive part 82 on its inner side. The two adhesive parts 82 can be bonded to each other. This type of strap 8 has a simple structure and is easy to process.
[0056] The adhesive part 82 can be provided on only a part of the binding part 81, or the adhesive part 82 can cover the entire binding part 81. With this configuration, the adhesive part 82 can also be attached to the user's skin.
[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model 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 or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
