Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a catheter fixing patch. Background Art

[0002] Medical catheters are widely used in treatment processes, such as infusion, blood transfusion, drainage, etc. How to fix the catheter on the patient's body surface and prevent the catheter from loosening or shifting during the fixation process is very important for the treatment process.

[0003] Currently, suture fixation and adhesive tape fixation are commonly used on the market. Due to the different operating habits and experience of specific operators, the fixation effects vary. Suture fixation requires puncturing the skin, and there is no way to ensure that the puncture hole is completely sterile, which can easily cause risks such as skin infection. Adhesive tape fixation can easily cause problems such as loosening and displacement of the catheter.

[0004] For example, a Chinese patent with publication number CN207532624U discloses a catheter fixing patch, which directly places the catheter on the adhesive layer on the top surface of the lower flannel cloth, and then sticks the upper flannel cloth on the adhesive layer on the top surface of the lower flannel cloth to fix the catheter; however, the fixing patch cannot surround and fix the catheter 360 degrees, which makes the catheter easy to loosen and shift, and the fixing effect is poor. Summary of the invention

[0005] The present application provides a catheter fixing patch, which solves the problem that the existing catheter fixing patch cannot surround and fix the catheter 360 degrees, causing the catheter to easily become loose or shifted.

[0006] The present application provides a catheter fixing patch, comprising a patch, wherein a first adhesive layer is provided in a side area of ​​the bottom surface of the patch for fixing the patch; a second adhesive layer is provided in a middle area of ​​the top surface of the patch, wherein the length of the second adhesive layer is greater than the outer circumference of the catheter, and the second adhesive layer is used to surround and fix the catheter.

[0007] In the technical solution provided in the present application, after one side of the patch is fixed to the patient's skin surface by the first adhesive layer, the other side of the patch can be folded upwards and the catheter can be wrapped 360 degrees around and fixed by the second adhesive layer on the top surface of the patch, which can effectively solve the problems of the catheter being easily loosened or shifted after being fixed, thereby improving the catheter fixing effect.

[0008] In certain embodiments, the second adhesive layer is a re-stickable medical adhesive. When the catheter is not firmly fixed or the catheter fixing position needs to be adjusted, the second adhesive layer can be torn off and then re-sticked.

[0009] In some embodiments, isolation tapes are provided at both ends of the top surface of the second adhesive layer, and the top surface of the isolation tapes is covered with a release film to prevent the second adhesive layer from being peeled off from the patch when the second adhesive layers are torn apart.

[0010] In some embodiments, the top surface of the patch is provided with a felt layer and a hook layer that cooperate with each other, and the felt layer and the hook layer are respectively located on both sides of the second viscose layer; by arranging the felt layer and the hook layer on both sides of the top surface of the patch, it is convenient to stick and fix the top surface of the patch around the catheter, and then further stick and fix it through the felt layer and the hook layer, thereby further improving the firmness of the catheter fixation.

[0011] In certain embodiments, a base sheet is adhered to the bottom surface of the patch via a first adhesive layer, a third adhesive layer is provided on the bottom surface of the base sheet, and the size of the base sheet is larger than the size of the patch; by adhering a base sheet with a larger size to the bottom surface of the patch, on the one hand, the adhesion area between the fixing patch and the patient's skin is increased, thereby improving the firmness of the fixing patch on the patient's skin; on the other hand, the fixing patch is prevented from being peeled off from the skin when subjected to the upward pulling force of the catheter.

[0012] In some embodiments, the top surface of the second adhesive layer is covered with a first release paper, and the bottom surface of the third adhesive layer is covered with a second release paper, so as to protect the adhesive layers on the top and bottom surfaces of the fixing patch.

[0013] In some embodiments, the second release paper includes a release origami and a release cover paper; a portion of the release origami covers one side of the third adhesive layer, and another portion is folded outward to form a folded edge; a portion of the release cover paper covers the other side of the third adhesive layer, and another portion covers the folded edge, so as to facilitate the sticking of the fixing patch.

[0014] In some embodiments, a positioning notch is provided on one or both sides of the substrate, and the position of the positioning notch corresponds to the position of the inner edge of the first adhesive layer. By providing the positioning notch on the side plate of the substrate, it is convenient to fix the catheter at a suitable position on the top surface of the patch.

[0015] In some embodiments, the patch is provided with a plurality of incisions, the incisions are oriented perpendicular to the length direction of the catheter, and the incisions are located in an area on one side of the patch away from the first adhesive layer. By providing the incisions on the patch, when the catheter is subjected to radial pulling force, the incisions can provide a reverse pulling force, thereby further preventing the catheter from loosening.

[0016] In some embodiments, the patch is provided with an avoidance hole for passing the three-way interface of the catheter. The avoidance hole is located in the area on one side of the patch away from the first adhesive layer, which is convenient for fixing the catheter with the three-way interface and has better applicability.

[0031] See also Figure 1-Figure 5An embodiment of the present application provides a catheter fixing patch, including a patch 1, a first adhesive layer 2 is provided in a side area of ​​the bottom surface of the patch 1, for fixing the patch 1; a second adhesive layer 3 is provided in a middle area of ​​the top surface of the patch 1, the length of the second adhesive layer 3 is greater than the outer circumference of the catheter 4, and the second adhesive layer 3 is used to surround and fix the catheter 4.

[0032] In the technical solution provided in the present application, after one side of the patch 1 is fixed on the patient's skin surface by the first adhesive layer 2, the other side of the patch 1 can be folded upward, and the catheter 4 can be wrapped 360 degrees around and fixed by the second adhesive layer 3 on the top surface of the patch 1, which can effectively solve the problems of the catheter 4 being easy to loosen or shift after being fixed, thereby improving the fixing effect of the catheter 4.

[0033] In some embodiments, the second adhesive layer 3 is a re-stickable medical adhesive. When the catheter 4 is not firmly fixed or the fixed position of the catheter 4 needs to be adjusted, the second adhesive layer 3 can be torn off and then re-sticked.

[0034] In a specific implementation process, the second adhesive layer 3 can be made of medical pressure-sensitive adhesive, which can be repeatedly pasted and peeled off to facilitate adjustment of the fixed position of the catheter 4.

[0035] Please continue reading Figures 1 to 3 In some embodiments, isolation tapes 5 are provided at both ends of the top surface of the second adhesive layer 3, and the top surface of the isolation tape 5 is covered with a release film to prevent the second adhesive layer 3 from being peeled off from the patch 1 when the second adhesive layers 3 that are stuck together are torn off (the second adhesive layer 3 is an integral structure. When the end of the second adhesive layer 3 is subjected to an upward pulling force, the second adhesive layer 3 is easily torn off as a whole. In this embodiment, isolation tapes 5 are affixed to both ends of the top surface of the second adhesive layer 3. In this way, when the second adhesive layers 3 that are stuck together are torn off, the end of the second adhesive layer 3 will not be subjected to an upward pulling force, so it is difficult to peel the entire second adhesive layer 3 off the surface of the patch 1).

[0036] Please continue reading Figures 1 to 3 In some embodiments, the top surface of the patch 1 is provided with a felt layer 6 and a hook layer 7 that cooperate with each other, and the felt layer 6 and the hook layer 7 are respectively located on both sides of the second viscose layer 3; by arranging the felt layer 6 and the hook layer 7 on both sides of the top surface of the patch 1, it is convenient to further adhere and fix the top surface of the patch 1 around the catheter 4 after pasting and fixing it, thereby further improving the firmness of the fixation of the catheter 4; in addition, the first viscose layer 2 is not provided on the bottom surface of one side of the patch 1 where the felt layer 6 is located, and the patch 1 can be wrapped around the catheter 4 by pinching the felt layer 6 by hand to fix the catheter 4.

[0037] Please continue reading Figures 1 to 3In some embodiments, a base sheet 8 is adhered to the bottom surface of the patch 1 through a first adhesive layer 2, and a third adhesive layer 9 is provided on the bottom surface of the base sheet 8, and the size of the base sheet 8 is larger than that of the patch 1; by pasting a larger base sheet 8 on the bottom surface of the patch 1, on the one hand, the pasting area between the fixing patch and the patient's skin is increased, and the firmness of the fixing patch on the patient's skin is improved; on the other hand, the fixing patch is prevented from being peeled off from the skin when subjected to the upward pulling force of the catheter 4 (since the size of the base sheet 8 is larger than that of the patch 1, when the base sheet 8 is subjected to an upward pulling force, the pulling force is located near the center of the base sheet 8, which can avoid the force position being located at the edge of the third adhesive layer 9. If the pulling force is located at the edge of the adhesive layer, it is easy to peel off the entire adhesive layer from the skin surface).

[0038] Please continue reading Figure 1 In some embodiments, the top surface of the second adhesive layer 3 is covered with a first release paper 10, and the bottom surface of the third adhesive layer 9 is covered with a second release paper, which can protect the adhesive layers on the top and bottom surfaces of the fixed sticker.

[0039] Please continue reading Figure 1 In some embodiments, the second release paper includes a release origami 11 and a release cover paper 12; a portion of the release origami 11 covers one side of the third adhesive layer 9, and the other portion is folded outward to form a folded edge; a portion of the release cover paper 12 covers the other side of the third adhesive layer 9, and the other portion covers the folded edge, so as to facilitate the sticking of the fixing patch.

[0040] In some embodiments, positioning notches (not shown in the figure) are provided on both sides of the substrate 8, and the positions of the positioning notches correspond to the positions of the inner edges of the first adhesive layer 2. By setting positioning notches on the side panels of the substrate 8, it is convenient to fix the catheter 4 at a suitable position on the top surface of the patch 1.

[0041] Please continue reading Figure 4 In some embodiments, the patch 1 is provided with a plurality of cutouts 13, the direction of the cutouts 13 is perpendicular to the length direction of the catheter 4, and the cutouts 13 are located in a side area of ​​the patch 1 away from the first adhesive layer 2. By providing the cutouts 13 on the patch 1, when the catheter 4 is subjected to radial pulling force, the cutouts 13 can provide a reverse pulling force, thereby further preventing the catheter 4 from loosening.

[0042] In a specific embodiment, the incision 13 can be U-shaped, "fish scale" shaped or long strip shaped, etc. Practice has proved that the portion of the patch 1 with the incision 13 has stronger elasticity than the other portions without the incision 13. When subjected to radial pulling force, it can provide reverse elastic force to prevent the catheter 4 from loosening.

[0043] In some embodiments, the patch 1 is provided with an avoidance hole 14 for passing the three-way interface 15 of the catheter 4. The avoidance hole 14 is located in the area on one side of the patch 1 away from the first adhesive layer 2, which is convenient for fixing the catheter 4 with the three-way interface 15 and has better applicability.

[0044] The method of using the fixing sticker of this embodiment is as follows:

[0045] First, tear off the second release paper on the bottom surface of the base sheet 8 and stick the fixing patch on the appropriate position of the patient's skin; then, tear off the first release paper 10 on the top surface of the patch 1, and place the catheter 4 on the second adhesive layer 3 on the top surface of the patch 1, so that the length direction of the catheter 4 is perpendicular to the length direction of the patch 1; then pinch the felt layer 6 on one side of the patch 1 to fold the patch 1, and after the patch 1 is wrapped around the catheter 4, stick the excess length of the adhesive layer on both sides of the catheter 4 together, and stick the felt layer 6 to the wool hook layer 7; when it is necessary to adjust the fixed position of the catheter 4, the felt layer 6 can be torn off the wool hook layer 7, and the patch 1 and the second adhesive layer 3 can be peeled off from the outer wall of the catheter 4, and after the fixed position of the catheter 4 is adjusted, it can be re-fixed.
