Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a fixation patch and a medical device. Background Technology

[0002] In clinical practice, various catheters are often left in place for extended periods during patient treatment, including central venous catheters, indwelling intravenous needles, urinary catheters, and gastric tubes. These catheters may remain in place for hours or days, or even months or a year. Medical catheters, as conduits connecting the inside and outside of the body, are widely used in the medical field, such as drainage tubes, infusion tubes, and transfusion vessels. Regardless of the type of medical catheter, effective fixation is crucial to prevent displacement, loosening, or dislodgement. However, current fixation methods typically use ordinary medical adhesive tape, which is not reusable. Utility Model Content

[0003] This application provides a fixation sticker to solve the problem that fixation stickers in the prior art cannot be reused.

[0004] To address the aforementioned technical problems, this application provides a fixing adhesive, comprising: a first adhesive layer including a first side and a second side; a second adhesive layer, one end of a third side of the second adhesive layer being adhered to the second side of the first adhesive layer, and the other end being movably disposed opposite to the first adhesive layer, the first side and the second side being opposing surfaces; and a release film layer disposed at both ends of a fourth side of the second adhesive layer, covering at least a portion of the fourth side, the fourth side and the third side being opposing surfaces; wherein the first side and the fourth side are adhesive.

[0005] The fixing adhesive also includes a double-sided adhesive layer, and one end of the third side of the second adhesive layer is bonded to the second side of the first adhesive layer via the double-sided adhesive layer; wherein the double-sided adhesive layer is a milky white adhesive layer, and the two ends of the double-sided adhesive layer are located on both sides of the center line of the first adhesive layer.

[0006] The first adhesive layer includes a first support layer and a first adhesive layer disposed on one side end face of the first support layer. The surface of the first adhesive layer facing away from the first support layer is a first side surface, and the surface of the first support layer facing away from the first adhesive layer is a second side surface.

[0007] The second adhesive layer includes a second support layer and a second adhesive layer disposed on one end face of the second support layer. The release film layer is bonded to both ends of the second adhesive layer. The surface of the second adhesive layer facing away from the second support layer is the fourth side, and the surface of the second support layer facing away from the second adhesive layer is the third side. The projection of the second adhesive layer on the second support layer covers at least nine-tenths of the second support layer.

[0008] The fixing sticker also includes a first release layer, which is connected to the first side of the first adhesive layer and covers the first side.

[0009] The fixing adhesive further includes a second release layer, which is at least partially connected to the fourth side of the second adhesive layer, covering the fourth side and at least part of the release film layer.

[0010] The release film layer includes a first release film unit and a second release film unit. The first release film unit is disposed at one end of the second adhesive layer corresponding to the double-sided adhesive layer, and the second release film unit is disposed at the other end of the second adhesive layer. When the fastener is fixed to the second adhesive layer, the second release film unit extends at least partially beyond the first release film unit.

[0011] In this case, the projection of the second adhesive layer onto the first adhesive layer covers at least three-fifths of the first adhesive layer.

[0012] The projection of the first adhesive layer onto the first support layer covers at least nine-tenths of the first support layer.

[0013] The first adhesive layer is a silicone gel layer.

[0014] To address the aforementioned issues, this application also provides a medical device comprising: a fixation patch, wherein the fixation patch is any of the fixation patches described above.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, this application adheres one end of the second side of the second adhesive layer to the second side of the first adhesive layer, and the other end of the second adhesive layer is movably disposed from the first adhesive layer. The fourth side of the second adhesive layer is adhesive, which can bond and fix the component to be fixed. Release film layers are provided at both ends of the fourth side of the second adhesive layer, so that when the component to be fixed is replaced, the bonding and detachment between the second adhesive layers can be completed through the release film layers, so that the fixing sticker has reusability.

[0026] Please see Figure 1 , Figure 1 This is a structural schematic diagram of the fixed-pattern cross-section provided in this application.

[0027] This application provides a fixing sticker. For example... Figure 1 and Figure 2As shown, the fixing adhesive of this embodiment includes: a first adhesive layer 10, a second adhesive layer 20, and a release film layer 30. The first adhesive layer 10 includes a first side surface 101 and a second side surface 102. Specifically, the first adhesive layer 10 includes two opposing end surfaces, namely the first side surface 101 and the second side surface 102, which are opposing surfaces. Correspondingly, the second adhesive layer 20 includes a third side surface 201 and a fourth side surface 202, which are opposing surfaces. One end of the third side surface 201 of the second adhesive layer 20 is bonded to the second side surface 102 of the first adhesive layer 10, and the other end is movably disposed opposite to the first adhesive layer 10. In other embodiments, the third side 201 of the second adhesive layer 20 can be adhered to the second side 102 of the first adhesive layer 10 near the center line, and both ends of the second adhesive layer 20 are movably disposed from the first adhesive layer 10. This can be specifically configured according to requirements, and this application does not impose specific limitations here. The release film layer 30 is disposed at both ends of the fourth side 202 of the second adhesive layer 20, covering at least a portion of the fourth side 202. The first side 101 and the fourth side 202 are adhesive.

[0028] In an optional embodiment, combined with Figure 7 As shown, the first adhesive layer 10 includes a first side 101 and a second side 102 opposite to each other, and one end of the second adhesive layer 20 is adhered to the second side 102 of the first adhesive layer 10. The first side 101 of the first adhesive layer 10 is adhesive, so that the first side 101 of the first adhesive layer 10 can be used to adhere the part to be fixed 70 to an external component (not shown), such as human skin. One end of the second adhesive layer 20 is fixedly adhered to the second side 102 of the first adhesive layer 10. The second adhesive layer 20 is disposed relative to the first adhesive layer 10 and is movably disposed, that is, the end of the second adhesive layer 20 that is fixedly connected to the first adhesive layer 10 is the fixed end, and the other end is the free end, that is, the second adhesive layer 20 can be bent relative to the first adhesive layer 10. Because the fourth side 202 of the second adhesive layer 20 is adhesive, when the second adhesive layer 20 is bent, the part to be fixed 70 can be bonded to the fourth side 202 of the second adhesive layer 20. The part to be fixed 70 can specifically be a catheter, infusion tube, etc. That is, when fixing the part to be fixed 70, the fourth side 202 of the second adhesive layer 20 can be bonded to the outer wall of the part to be fixed 70, and the fourth side 202 of the second adhesive layer 20 in areas other than the part to be fixed 70 can be bonded to each other, thereby completing the fixing of the part to be fixed 70.

[0029] In this embodiment, a release film layer 30 is provided on the fourth side surface 202 of the second adhesive layer 20. Specifically, two release film layers 30 can be provided, one of which is provided at one end of the first adhesive layer 10 of the second adhesive layer 20, and the other is provided at the other end of the second adhesive layer 20. When the member to be fixed 70 is fixed by bending the second adhesive layer 20, the fourth side surface 202 of the second adhesive layer 20 can be bonded and fixed to the member to be fixed 70. The fourth side surfaces 202 of the second adhesive layer 20 that are bonded to areas other than the member to be fixed 70 can be bonded and fixed to each other. The release film layers 30 are provided at both ends of the second adhesive layer 20. When the member to be fixed 70 is fixed by bending the second adhesive layer 20, the two release film layers 30 can be movably disposed between each other. Thus, when the member to be fixed 70 is bonded, the fourth side surface 202 of the second adhesive layer 20 can be bonded to the release film layer 30 of the second adhesive layer 20. When bonding the fastener 70, it is necessary to ensure that the release film layer 30 on the movable end of the second adhesive layer 20 extends at least partially beyond the fourth side 202 of the second adhesive layer 20, thereby ensuring the movable setting of the release film layer 30. When it is necessary to replace the fastener 70, the second adhesive layer 20 can be peeled off by the release film layer 30 on the second adhesive layer 20 to remove the fastener 70 to be replaced, and then the second adhesive layer 20 can be bent to complete the replacement of the corresponding fastener 70.

[0030] In an optional embodiment, one end of the second adhesive layer 20 is fixed to the first adhesive layer 10. Specifically, one end of the second adhesive layer 20 can be adhered to a position near the centerline of the first adhesive layer 10, thereby positioning the fixing position of the member to be fixed 70 when fixing it. Correspondingly, the third side 201 of the second adhesive layer 20 is adhered to the second side 102 of the first adhesive layer 10, and the first side 101 of the first adhesive layer 10 and the fourth side 202 of the second adhesive layer 20 are adhesive, so that the first side 101 of the first adhesive layer 10 can be adhered to an external component to fix the fixing patch and the member to be fixed 70, for example, on human skin, and the fourth side 202 of the second adhesive layer 20 can be used to fix the member to be fixed. When it is necessary to replace the fastener 70, the second adhesive layer 20 can be detached through the release film layer 30, that is, the release film layer 30 is peeled off, thereby causing the second adhesive layer 20 to peel off. Then the fastener 70 is replaced, and the fourth side 202 of the second adhesive layer 20 is bent again to bond and fix it, so as to complete the replacement of the fastener 70.

[0031] In the above embodiment, by adhering one end of the second side surface 102 of the second adhesive layer 20 to the second side surface 102 of the first adhesive layer 10, and the other end of the second adhesive layer 20 being movably disposed from the first adhesive layer 10, the fourth side surface 202 of the second adhesive layer 20 is adhesive, which can be used to bond and fix the member to be fixed 70. Release film layers 30 are provided at both ends of the fourth side surface 202 of the second adhesive layer 20, so that when the member to be fixed 70 is replaced, the bonding and detachment between the second adhesive layers 20 can be completed through the release film layers 30, so that the fixing sticker is reusable.

[0032] In an optional embodiment, such as Figure 1 As shown, the fixing adhesive also includes a double-sided adhesive layer 40. One end of the third side 201 of the second adhesive layer 20 is bonded to the second side 102 of the first adhesive layer 10 via the double-sided adhesive layer 40. The double-sided adhesive layer 40 bonds the first adhesive layer 10 and the second adhesive layer 20, and can bond one end of the third side 201 of the second adhesive layer 20 to the second side 102 of the first adhesive layer 10. The double-sided adhesive layer 40 is a milky white adhesive layer. Both ends of the double-sided adhesive layer 40 are positioned at the center line of the first adhesive layer 10. Specifically, the distance between the two ends of the double-sided adhesive layer 40 and the center line of the first adhesive layer 10 is one-quarter to one-thirtieth of the length of the first adhesive layer 10. Preferably, the distance is one-tenth to one-twentieth of the length. This is sufficient to ensure that the part to be fixed 70 can be close to or located at the center line of the first adhesive layer 10 when fixing it. The specific setting can be adjusted according to requirements, and this application does not impose specific limitations. By making the double-sided adhesive layer milky white, the double-sided adhesive layer 40 can be used to position the part to be fixed 70, thus facilitating its fixation. Furthermore, both ends of the double-sided adhesive layer 40 are positioned at the center line of the first adhesive layer 10. That is, the double-sided adhesive layer 40 is located near the centerline of the first adhesive layer 10, and the double-sided adhesive layer 40 is a milky white adhesive layer, so as to fix the position of the component 70 to be fixed. Specifically, one end face of the double-sided adhesive layer 40 is bonded to the second side face 102 of the first adhesive layer 10, and the other end face is bonded to the third side face 201 of the second adhesive layer 20. One end of the third side face 201 of the second adhesive layer 20 is bonded to the second side face 102 of the first adhesive layer 10 via the double-sided adhesive layer 40, so that one end of the second adhesive layer 20 is bonded to the position near the centerline of the first adhesive layer 10 via the double-sided adhesive layer 40.

[0033] In an optional embodiment, such as Figure 3As shown, the first adhesive layer 10 includes a first support layer 103 and a first adhesive layer 104 disposed on one end face of the first support layer 103. The surface of the first adhesive layer 104 facing away from the first support layer 103 is a first side surface 101, and the surface of the first support layer 103 facing away from the first adhesive layer 104 is a second side surface 102. The third side surface 201 of the second adhesive layer 20 is bonded to the second side surface 102 of the first adhesive layer 10 via a double-sided adhesive layer 40, that is, the third side surface 201 of the second adhesive layer 20 is bonded to the first support layer 103 via a double-sided adhesive layer 40. The surface of the first support layer 103 away from the first adhesive layer 104 is the first side surface 101 of the first support layer 103. The first side surface 101 of the first adhesive layer 104 can be used to bond external components, thereby fixing the fixing sticker and the component 70 to be fixed. Wherein, the projection of the first adhesive layer 104 on the first support layer 103 covers at least nine-tenths of the first support layer 103, that is, when the fixing patch is attached to human skin, the first adhesive layer 104 can be prevented from exceeding the first support layer 103, so as to avoid the first adhesive layer 104 from overflowing.

[0034] In an optional embodiment, the fixing patch further includes a first release layer 50, which is at least partially connected to a first side surface 101 of the first adhesive layer 10, covering the first side surface 101. The first release layer 50 is at least partially connected to the first side surface 101 of the first adhesive layer 10, meaning the first release layer 50 is bonded to the end face of the first adhesive layer 104 away from the first support layer 103, and is bonded and fixed via the first adhesive layer 104. When it is necessary to fix the fixing patch via the first adhesive layer 104, the first release layer 50 can be peeled off from the first adhesive layer 104 to expose the first adhesive layer 104, thereby fixing the fixing patch to the component 70 to be fixed. The first adhesive layer 10 includes a first support layer 103, thereby bonding the double-sided adhesive layer 40 to the first support layer 103, and allowing the second adhesive layer 20 to be bonded to the end face of the first support layer 103 via the double-sided adhesive layer 40. The first release layer 50 may specifically include two separately configured first release layers 50, which can be set according to requirements, and this application does not make specific limitations here.

[0035] In an optional embodiment, such as Figure 4As shown, the second adhesive layer 20 includes a second support layer 203 and a second adhesive layer 204 disposed on one end face of the second support layer 203. A release film layer 30 is bonded to both ends of the fourth side surface 202 of the second adhesive layer 204. The surface of the second adhesive layer 204 facing away from the second support layer 203 is the fourth side surface 202, and the surface of the second support layer 203 facing away from the second adhesive layer 204 is the third side surface 201. When one end of the second adhesive layer 20 is bonded to the first adhesive layer 10, the second support layer 203 can be positioned facing the first support layer 103, that is, the second support layer 203 of the second adhesive layer 20 and the first support layer 103 of the first adhesive layer 10 are positioned opposite each other. Then, the first support layer 103 and the second support layer 203 are bonded and fixed using a double-sided adhesive layer 40, thereby fixing one end of the second support layer 203 to the end face of the first support layer 103 away from the first adhesive layer 104, thus completing the fixation of the first adhesive layer 10 and the second adhesive layer 20. The second adhesive layer 20 includes a second adhesive layer 204. The surface of the second adhesive layer 204 away from the second support layer 203 is a fourth side surface 202. The release film layer 30 can be bonded to the fourth side surface 202 of the second adhesive layer 204 and is bonded to both ends of the second adhesive layer 204 to cover part of the second adhesive layer 204. The second adhesive layer 204 is partially exposed, and the exposed part of the second adhesive layer 204 can be used for bonding and fixing the member 70 to be fixed.

[0036] In this embodiment, the release film layer 30 is disposed at both ends of the second adhesive layer 204, thereby exposing a portion of the second adhesive layer 204. The length of the exposed portion of the second adhesive layer 204 needs to be greater than the circumference of the part to be fixed 70, so that after bending the second adhesive layer 20, a portion of the second adhesive layer 204 can be bonded and fixed together. The length of the exposed portion of the second adhesive layer 204 can be specifically set according to requirements, and this application does not impose a specific limitation.

[0037] The second adhesive layer 204 is smaller than the second support layer 203. The surface of the second support layer 203 away from the second adhesive layer 204 is the third side surface 201, and the surface of the second adhesive layer 204 away from the second support layer 203 is also the third side surface 201. Since the size of the second adhesive layer 204 is smaller than the size of the second support layer 203, the size of the fourth side surface 202 of the second adhesive layer 20 is smaller than the size of the third side surface 201. Specifically, the projected size of the second adhesive layer 204 on the second support layer 203 can occupy nine-tenths of the size of the second support layer 203. Therefore, when the second adhesive layer 20 is bent through the release film layer 30, the member to be fixed 70 can be fixed. Because the size of the second adhesive layer 204 is smaller than the size of the second support layer 203, excess adhesive in the second adhesive layer 20 can be effectively avoided, meaning the second adhesive layer 204 cannot extend beyond the sidewall of the second support layer 203. When the second adhesive layer 20 is bent to fix the part 70 to be fixed, the second adhesive layer 204 can be prevented from tilting on the second support layer 203, thereby avoiding the overflow of the second adhesive layer 204.

[0038] In an optional embodiment, the fixing adhesive further includes a second release layer 60, which is at least partially connected to the fourth side surface 202 of the second adhesive layer 20, covering the fourth side surface 202 and at least a portion of the release film layer 30. The second release layer 60 is disposed on the fourth side surface 202 of the second adhesive layer 204, and release film layers 30 are disposed at both ends of the second adhesive layer 204. The second release layer 60 is disposed on the end face of the second adhesive layer 204 away from the second support layer 203. The fourth side surface 202 of the second adhesive layer 204 can be completely protected by the release film layer 30 and the second release layer 60. When the second release layer 60 is disposed, it can cover a portion of the release film layer 30. Specifically, the second release layer 60 can cover the second adhesive layer 20 disposed at the fixed end and can cover a portion of the release film layer 30 disposed on the second adhesive layer 204 at the movable end. Therefore, when fixing the fastener 70, it is easy to peel off the second release layer 60 provided on the release film layer 30.

[0039] In an optional embodiment, the projection of the second adhesive layer 20 onto the first adhesive layer 10 covers at least three-fifths of the first adhesive layer 10. One end of the second adhesive layer 20 is fixedly disposed on the second side 102 of the first adhesive layer 10. Specifically, the second adhesive layer 20 is adhered and fixed to the centerline near the first adhesive layer 10 via a double-sided adhesive layer 40. That is, the projection of the second adhesive layer 20 onto the first adhesive layer 10 covers at least three-fifths of the first adhesive layer 10, and the fact that one end of the second adhesive layer 20 is disposed near the centerline of the first adhesive layer 10 can effectively position the member 70 to be fixed.

[0040] The first adhesive layer 104 is a silicone gel layer. When the fixation patch is attached to an external component, such as human skin, the first adhesive layer 104 is set as a silicone gel layer. When the fixation patch is removed, it will protect the human skin, that is, avoid tearing the human skin, and effectively improve the user experience of the patient.

[0041] In an optional embodiment, such as Figure 1 and Figure 6As shown, the release film layer 30 includes a first release film unit 301 and a second release film unit 302. The first release film unit 301 is disposed at one end of the second adhesive layer 20 corresponding to the double-sided adhesive layer 40, and the second release film unit 302 is disposed at the other end of the second adhesive layer 20. The first release film unit 301 and the second release film unit 302 can be specifically configured as colored release films to facilitate the positioning of the release film layer 30. When the fastener 70 is fixed to the second adhesive layer 20, the second release film unit 302 extends at least partially beyond the first release film unit 301. That is, the second release film unit 302 is disposed at the free end of the second adhesive layer 20, and the first release film unit 301 is disposed at the fixed end of the second adhesive layer 20. The second release film unit 302 can be used to bend the second adhesive layer 20 to fix the fastener 70. After the component 70 is fixed, the second release film unit 302 can partially extend beyond the first release film unit 301, so that when the component 70 is replaced later, the second release film unit 302 can be used to peel off the second adhesive layers 204 that are bonded together. That is, when the component 70 is fixed via the second adhesive layer 204, the projections of the first release film unit 301 and the second release film unit 302 on the second adhesive layer 204 can be staggered. The length of the second release film unit 302 along the length of the second adhesive layer 204 can be greater than the length of the first release film unit 301 along the length of the second adhesive layer 204. In other embodiments, after the component 70 is fixed, the first release film unit 301 can extend partially beyond the second release film unit 302. The specific setting can be determined according to the requirements, and this application does not impose a specific limitation here.

[0042] In a specific application scenario, such as Figure 5 and Figure 6As shown, when a patient needs to use the fixation patch, the first release layer 50 can be peeled off first, exposing the first adhesive layer 104 of the first adhesive layer 10. The first adhesive layer 104 is then bonded to the patient's skin, thus fixing the fixation patch. When fixing the object to be fixed 70, the second release layer 60 can be peeled off to expose the release film layer 30 and the second adhesive layer 204. Then, the object to be fixed 70 corresponding to the double-sided adhesive layer 40 is placed on the second adhesive layer 204. The second release film unit 302 on the free end of the second adhesive layer 204 is pulled, causing the second adhesive layer 204 and the second support layer 203 to bend, so that the second adhesive layer 204 completely wraps around the outer wall of the object to be fixed 70, and the second adhesive layer 204 covering the area outside the object to be fixed is bonded and fixed, thus completing the fixation of the object to be fixed 70. Furthermore, when fixing the component 70, the first release film unit 301 and the second release film unit 302 can be misaligned, thereby allowing the edges to peel off the mutually bonded second adhesive layers 204 via the second release film unit 302. When it is necessary to replace the component 70, the mutually bonded second adhesive layers 204 can be peeled off via the second release film unit 302, and the component 70 can be replaced, and then the component 70 can be re-bonded.
