Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an infusion connector fixing patch. Background Technology

[0002] Indwelling intravenous catheters mainly refer to indwelling intravenous catheters (PIVC) and central venous catheters (PICC and CVC). Both include an infusion connector and a catheter connected to the connector. Compared to the catheter, the infusion connector is relatively large, making it prone to irregular movement during use and posing significant risks. During infusion and indwelling, the infusion connector is easily subjected to external pressure and scraping, which can lead to displacement or even dislodgement, especially in active children who are at higher risk.

[0003] Current clinical protocols use adhesive tape for traditional fixation via the elevated platform method: the catheter needs to be 0.5 cm above the skin, the tape is placed in the center of the catheter and wraps around it 360°, and then tightly adhered to the skin on both sides. Because the elevated platform method only provides localized fixation of the catheter and cannot directly and effectively secure the infusion connector, it cannot prevent the tape from detaching due to irregular movement of the infusion connector.

[0004] While shaking of the IV connector usually won't pull out the needle, it is a significant factor that can cause indwelling intravenous needles to dislodge, especially when the patient is unconscious or asleep during the indwelling period. If the IV connector is not securely fixed, the indwelling intravenous needle can easily dislodge, leading to serious medical safety incidents such as blood leakage and cross-infection. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model discloses an infusion connector fixing sticker, which can achieve comprehensive and effective fixing of the infusion connector while also providing integrated fixing of the catheter, fundamentally solving the infusion safety hazard caused by displacement or even detachment of the infusion connector due to external pressure or scraping.

[0006] The specific technical solution of this utility model is as follows:

[0007] An infusion connector fixing patch, comprising:

[0008] The fixing patch has a connector fixing part on one side for fixing the infusion connector, and a release paper on the other side. The release paper is peeled off the fixing patch to attach the fixing patch to the human skin for fixation.

[0009] The connector fixing part is at least one of an adhesive part and a limiting structure; the fixing adhesive is provided with a gap for the catheter to pass through when the infusion connector is connected.

[0010] This application features a connector fixing part and a gap part on the fixing adhesive. The connector fixing part can comprehensively and effectively fix the infusion connector, preventing irregular shaking of the infusion connector; the gap part provides a channel for the catheter connected to the infusion connector, which not only makes the infusion connection operation very convenient, but also allows the catheter to be effectively attached to the skin for fixation. It realizes a multi-integrated fixation of the infusion connector by the skin, connector fixing part and catheter, thereby effectively avoiding the infusion safety hazards caused by displacement or even detachment of the infusion connector due to external pressure or scratches during use.

[0011] Preferably, the fixing adhesive includes a first adhesive and a second adhesive that are in contact with each other, the joint fixing part is disposed on the first adhesive; the gap is formed between the first adhesive and the second adhesive.

[0012] The second adhesive patch is used to fix the catheter connected to the infusion connector to the human skin.

[0013] The fixing adhesive of this application is divided into two parts: a first adhesive adhesive and a second adhesive adhesive. The first adhesive adhesive can be applied to the human skin and fixed in place before the second adhesive adhesive. After the infusion connector is fixed, the catheter is then applied to the human skin and fixed in place using the second adhesive adhesive. This facilitates use and provides an integrated fixation of the infusion connector and the catheter.

[0014] Preferably, the second adhesive patch includes:

[0015] A reference section is used to secure a catheter passing through the gap to the human skin; and

[0016] At least one connecting portion is connected to the first adhesive, and the connecting portion is connected to the base portion.

[0017] In this application, the base portion of the second adhesive patch ensures that it can effectively fix the catheter, while at least one connecting portion connected to the first adhesive patch ensures that the base portion will not detach from the first adhesive patch, thus ensuring that the infusion connector and the catheter are fixed in one piece; the various connection methods of the second adhesive patch ensure ease of use.

[0018] Preferably, the first adhesive patch has a convex structure, and the protrusion of the first adhesive patch extends into the inner side of the second adhesive patch.

[0019] When the first adhesive patch of this application has a convex structure in the center, it not only forms a gap with the second adhesive patch to facilitate the infusion connection operation, but also effectively ensures the area of ​​each patch adhering to the human skin, thereby improving the product's durability and stability.

[0020] Preferably, the connecting portion has two parts;

[0021] One of the connecting parts is connected to the first adhesive strip, and the other connecting part is separate from the first adhesive strip;

[0022] Alternatively, both connecting parts are connected to the first adhesive patch.

[0023] In this application, the two connecting parts have two different configurations, which can expand the product's applicability and allow users to flexibly choose according to their actual needs, thereby improving ease of use.

[0024] Preferably, the release paper includes a portion one adapted to a first adhesive and a portion two adapted to a second adhesive, wherein the portion one and the portion two are separately disposed.

[0025] The release paper in this application includes Part One and Part Two, which allows the first and second adhesive strips to be used sequentially and more closely match the product's usage steps. At the same time, it effectively prevents the second adhesive strip from adhering to impurities or other items before application, further improving the user experience of medical staff.

[0026] Preferably, the end of the second adhesive patch away from the first adhesive patch is provided with a protrusion extending outward toward the outside of the second adhesive patch, for attaching to the skin along the circumference of the human arm.

[0027] In this application, the second adhesive patch is provided with a raised patch, which can effectively increase the skin adhesion area of ​​the second adhesive patch, and further improve the adhesion stability of the second adhesive patch by attaching it along the circumference of the human arm.

[0028] Preferably, the limiting structure includes two sets of fixing plates arranged opposite to each other, with a receiving gap formed between the two sets of fixing plates, for engaging at least a portion of the infusion connector within the receiving gap;

[0029] Alternatively, the limiting structure may be a limiting piece.

[0030] In this application, the limiting structure is simple and easy to implement. While ensuring the fixation effect on the infusion connector, it effectively reduces the production difficulty and cost of the product. The product is not only simple, effective and easy to operate, but also ensures that it will not be difficult to serve patients due to excessive use costs.

[0031] Preferably, the accommodating gap is a gap with a straight structure;

[0032] Alternatively, the accommodating gap has a Y-shaped structure, including intersecting and connected gap one and gap two;

[0033] Alternatively, the accommodating gap may be at least one snap-fit ​​groove on the limiting piece.

[0034] In this application, the accommodating gap has two structures: a straight structure and a Y-shaped structure. These two structures can match different types of infusion connectors. In addition, especially for fixing different numbers of straight infusion connectors, particularly central venous catheters (PICC and CVC), multiple infusion connectors can be fixed, thereby meeting the needs of multiple clinical scenarios and effectively improving the practicality of the product.

[0035] Preferably, a pad is provided on the side of the joint fixing part near the second adhesive.

[0036] This application features a base that better fits the long catheter connector structure of the needleless positive pressure infusion connector, effectively ensuring a stable fixation and preventing the positive pressure connector from warping or even falling off under pressure, thereby further improving the stability of the infusion connector fixation.

[0037] Compared with existing technologies, this invention can effectively fix indwelling intravenous needles on human skin. It uses a first adhesive patch to attach and fix the needle to the skin, and then uses a connector fixing part on the first adhesive patch to fully fix the infusion connector. Finally, a second adhesive patch attaches the catheter connected to the infusion connector to the skin for fixation. Structurally, this invention satisfies the requirements of the first adhesive patch attaching to the skin for fixation, the connector fixing part fixing the infusion connector to the first adhesive patch, and the second adhesive patch fixing the catheter to the skin. This achieves a multi-layered, integrated fixation of the infusion connector using the skin, connector fixing part, and catheter, thus better meeting the requirements for stable use.

Detailed Implementation

[0046] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0047] like Figure 1 , Figure 2 As shown, an infusion connector fixing patch 100 includes a fixing patch 100, one side of which is provided with a connector fixing part 200 for fixing the infusion connector, and the other side of which is provided with release paper 400. The release paper 400 is peeled off from the fixing patch 100 to attach the fixing patch 100 to the human skin for fixation. The connector fixing part 200 is at least one of an adhesive member 210 and a limiting structure. The fixing patch 100 is provided with a gap 300 for the catheter connected to the infusion connector to pass through.

[0048] The above structure can effectively attach the infusion connector to at least one of the adhesive part 210 and the limiting structure, thereby ensuring that the infusion connector is not easy to shake or even fall off.

[0049] In this embodiment, the fixing patch 100 includes a first adhesive patch 110 and a second adhesive patch 120 that are in contact with each other. The connector fixing part 200 is disposed on the first adhesive patch 110. The gap part 300 is formed between the first adhesive patch 110 and the second adhesive patch 120. The second adhesive patch 120 is used to fix the catheter connected to the infusion connector to the human skin.

[0050] In this embodiment, the first adhesive patch 110 has a convex structure, and the second adhesive patch 120 has a concave structure, with the protruding part of the first adhesive patch 110 extending into the inner side of the second adhesive patch 120. This structure is simple, easy to form, and convenient for medical personnel to use. In this embodiment, a folding part, such as a folding line, is provided between the first adhesive patch 110 and the second adhesive patch 120. In specific use, firstly, the second adhesive patch 120 is folded towards the first adhesive patch 110 with the folding line as a reference, so that the gap 300 is clearly exposed, allowing the infusion connector to easily pass through the gap 300 and be fixed at the connector fixing part 200. Then, the second adhesive patch 120 is reset. Then, the release paper 400 is peeled off, allowing the first adhesive patch 110 and the second adhesive patch 120 to adhere to the skin, and the catheter is fixed to the skin, thereby achieving overall fixation of the infusion connector.

[0051] In this embodiment, the second adhesive patch 120 includes a base portion 121 and at least one connecting portion 122 connected to the first adhesive patch 110; the base portion 121 is used to fix the conduit passing through the gap portion 300 to the human skin; the connecting portion 122 is connected to the base portion 121. This structure can effectively meet the requirements for adhesion to human skin. Furthermore, there are two connecting portions 122; such as... Figure 1 As shown, both connecting portions 122 are connected to the first adhesive patch 110. It can be used according to the above operation method. In some other embodiments, such as... Figure 2 As shown, one connector 122 is connected to the first adhesive patch 110, while the other connector 122 is separate from the first adhesive patch 110. Specifically, in use, the first adhesive patch 110 can be first attached to the skin for fixation, then the infusion connector can be snapped in place. Next, the connector 122 separated from the first adhesive patch 110 can be lifted to allow the catheter to be inserted into the gap 300. Then, the base portion 121 of the second adhesive patch 120 can be used to attach the catheter to the skin for fixation, thus providing medical personnel with a variety of operating methods.

[0052] More specifically, if the infusion connector is for a PIVC (indwelling intravenous catheter), before the first infusion puncture, the infusion connector of the PIVC generally needs to be connected to the infusion set for air removal before the puncture. Since it is always connected to the infusion set, the infusion connector cannot pass directly through the gap 300. Therefore, by separating the connecting part 122 as described above, the infusion connector can pass directly through the gap 300 while ensuring that the base part 121 of the second adhesive 120 fixes the catheter connected to the infusion connector, without affecting the normal infusion operation. When changing dressings for a second infusion with a PIVC (indwelling intravenous catheter), since there is no need to connect the infusion connector to the infusion set for air removal beforehand, the infusion connector can pass directly through the gap 300. Therefore, both connecting parts 122 can simultaneously connect to the first adhesive patch 110. This connection method effectively improves the stability of the connection between the second adhesive patch 120 and the first adhesive patch 110, as well as the firmness of the second adhesive patch 120 on the skin, making it especially suitable for active children. Similarly, when using infusion connectors for central venous catheters (PICC and CVC), there is no need for air removal beforehand or connection to the infusion set. Therefore, the infusion connector can pass directly through the gap 300 without affecting normal operation. Thus, for single-lumen central venous catheters (PICC and CVC), the appropriate fixation patch 100 can be selected according to the patient's needs. However, when using a multi-lumen central venous catheter, due to the presence of multiple infusion connectors, a structure where both connectors 122 are connected to the first adhesive patch 110 can be selected. This offers greater stability. In use, the connector fixing part 200 fixes one of the infusion connectors (any connector for a dual-lumen catheter, the middle connector for a triple-lumen catheter, or any middle connector for a quadruple-lumen catheter), and then the second adhesive patch 120 is used to attach it to the other infusion connectors and the infusion catheter. It should be noted that the second adhesive patch 120 is used to fix the catheter connected to the infusion connector to the skin, which is only one of its functions. In the aforementioned application scenario with multiple infusion connectors, based on the structure of the fixing patch 100 itself, the two connectors 122 of the second adhesive patch 120 can also be used to directly fix the infusion connectors. That is to say, the primary function of the second adhesive patch 120 is to fix the catheter connected to the infusion connector, and its secondary function is to assist in fixing the infusion connector.

[0053] like Figure 2 As shown, in this embodiment, the release paper 400 includes a first portion 410 adapted to the first adhesive 110 and a second portion 420 adapted to the second adhesive 120, wherein the first portion 410 and the second portion 420 are separately disposed.

[0054] Because the release paper 400 is provided with part one 410 and part two 420, part one 410 and part two 420 can be torn apart separately according to operational needs during actual use. This prevents the infusion connector, tubing, or other impurities from sticking to the second adhesive patch 120 when passing through the gap 300, reducing the difficulty of operation and preventing contamination of the adhesive surface of the second adhesive patch 120, thus improving safety and ensuring the stability of the second adhesive patch 120 when attached to the skin. Furthermore, the end of the second adhesive patch 120 away from the first adhesive patch 110 is provided with a protruding tab 123 extending outward from the second adhesive patch 120 for attaching to the skin circumferentially along the human arm. In this embodiment, there are two protruding tabs 123 located laterally to the second adhesive patch 120, which can be attached to the skin around the arm, increasing the firmness of the attachment and further improving the fixation stability. Compared with other solutions that increase the attachment area of ​​the second adhesive patch 120, this embodiment has a simple structure, is easy to operate, and has high reliability. In practical use, firstly, peel off the release paper portion 410 to attach the first adhesive patch 110 to the skin for fixation; then, fold the connecting portions 122 on both sides of the second adhesive patch 120 toward the first adhesive patch 110 to expose the gap portion 300, allowing the infusion connector to easily pass through the gap portion 300 and be fixed at the connector fixing portion 200; then, reset the second adhesive patch 120 and the connecting portions 122 on both sides, and peel off the second release paper portion 420 again, so that the base portion 121 of the second adhesive patch 120 attaches the catheter connected to the infusion connector to the skin for fixation, and further attach the convex patch 123 to the skin for reinforced fixation on both sides.

[0055] like Figure 3 , Figure 4 As shown, in another technical solution of this embodiment, the connector fixing part 200 is a limiting structure. Specifically, the limiting structure includes two sets of fixing pieces 220 arranged opposite to each other, with a receiving gap 230 formed between the two sets of fixing pieces 220, for engaging at least a portion of the infusion connector within the receiving gap 230. Depending on actual needs, receiving gaps 230 with different structures can be used to achieve the purpose of engaging the infusion connector.

[0056] Generally speaking, infusion connectors are mainly divided into straight connectors and Y-type connectors. Regarding the straight type, such as... Figure 3 As shown, the accommodating gap 230 is a gap 231 with a straight structure, thereby matching the straight structure. For Y-type connectors, such as... Figure 4 As shown, the accommodating gap 230 includes intersecting and interconnected gap one 231 and gap two 232. Similarly, this structure is used to match the specific structure of the Y-shaped connector.

[0057] When in use, insert the infusion connector into the receiving gap 230. At this time, the two sets of fixing plates 220 will squeeze and clamp the infusion connector, thereby completing the clamping and fixing of the infusion connector.

[0058] It should be noted that the fixing piece 220 can be a single integral sheet-like fixing structure or multiple intermittently arranged sheet-like fixing structures. Both of these structures and their simple variations should also be included within the scope of protection of this application. In some embodiments, the fixing piece 220 can be made of a rigid material, such as plastic, with its root integrally connected to the fixing patch 100, thereby achieving snap-fit ​​fixing of the infusion connector; in other embodiments, the fixing piece 220 is made of an elastic material, such as rubber, and the infusion connector can also be snap-fit ​​fixed by the deformation of the fixing piece 220 itself.

[0059] In another technical solution of this embodiment, the limiting structure is a limiting piece 240, and further, the accommodating gap is at least one snap-fit ​​groove on the limiting piece 240. Specifically, when using multi-lumen central venous catheters (PICC and CVC) clinically, since they have multiple straight infusion connectors, it is advisable to choose a scheme using the receiving gap 230 as a locking groove. Multiple straight infusion connectors can be locked into the locking groove, which has a greater stability advantage. The locking groove has a groove 241 in the middle, and grooves 242 and 243 on both sides of groove 241. The method is described with three infusion connectors. In use, firstly, use groove 241 on the connector fixing part 200 to select and fix one infusion connector (any connector for double lumen, the middle connector for triple lumen, and any middle connector for quadruple lumen). The other two infusion connectors are locked into grooves 242 and 243 respectively. Next, use the two connecting parts 122 of the second adhesive 120 to assist in fixing the infusion connectors. Then, use the base part 121 of the second adhesive 120 to attach all the infusion connectors to the skin through the connected catheter and fix them. It should be noted that, in this embodiment, the adhesive 210 and the limiting structure can be used simultaneously in the same fixing sticker.

[0060] like Figure 5 , Figure 6 As shown, in this embodiment, a pad 500 is provided on the side of the connector fixing part 200 near the second adhesive 120.

[0061] The infusion connector has two forms: a heparin cap and a positive pressure connector. For the heparin cap type, the diameter of its conical connector is not significantly different from the diameter of its middle section, so it can be properly fixed in the connector fixing part 200. However, for the positive pressure connector, the diameter of its long tubing connector seat is much smaller than the diameter of its middle section. Therefore, when its tail is under pressure, it may lift up or even fall off. Therefore, this embodiment fills the diameter difference between its tail and middle sections by setting a pad 500, which effectively avoids lifting or falling off due to leverage when the tail is under force. In other words, the pad 500 can compensate for the tubing diameter, reduce the gap difference in the structure to avoid prying, and ensure that the infusion connector does not shake up and down in the plane, thereby achieving the purpose of further limiting the position.

[0062] It should also be noted that when the connector fixing part is a limiting structure, the pad 500 can be located inside or outside the gap 231. Alternatively, one part of the pad 500 can be located inside the gap 231, and the other part outside. All of these configurations can achieve tail diameter compensation for the infusion connector to meet stability requirements.

[0063] Typically, the fixation patch 100 in this embodiment also needs to follow the standard of tension-free adhesion to the skin. Similar to traditional sterile transparent dressings, a ring-shaped release paper is usually provided on the opposite side of the release paper 400 to facilitate holding the fixation patch 100 with force around it, thereby avoiding haphazard adhesion and enabling quick tension-free adhesion.

[0064] Based on the above embodiments, when using this embodiment, it can also be integrated with the traditional sterile transparent dressing design, especially for intravenous indwelling needles (PIVC). The fixation of the infusion puncture point and the infusion connector is integrated, which can reduce the irritation of the adhesive to the skin and make it more stable, while making the U-shaped fixation of the infusion catheter tail end more standardized.

[0065] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
