Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a combination fixation patch for fixing clinical vascular puncture catheters. Background Technology
[0002] Currently used fixation tapes do not differentiate between arteries and veins and all use a uniform specification of fixation tape. When used alone, they can perform the basic function of fixing the catheter and preventing slippage. However, in patients who need to undergo invasive arterial pressure monitoring and intravenous drug administration during the procedure, the radial artery puncture site may be covered by the venous fixation tape before puncture, resulting in incomplete exposure of the puncture site, difficulty in positioning, and difficulty in ensuring the disinfection range.
[0003] After puncture, at the end of the operation, the arterial catheter is usually removed first to end the arterial catheterization task, but the venous catheter needs to be retained for returning to the ward to continue intravenous infusion treatment. The fixation patch currently used has the problem of patch adhesion. During the separation process, it often affects the fixation of the vein, leading to vein slippage, kinking, leakage, and even needing to remove the venous patch and refix it, causing a lot of inconvenience and trouble for clinical work.
[0004] In addition, in the process of applying pressure to stop bleeding after artery removal, the traditional procedure requires placing a cotton ball at the bleeding point, initially fixing it with tape, and then applying the pressure hemostatic device. This is a cumbersome procedure, and the tape may also stick to the venous dressing during the initial fixation. Therefore, the existing fixation dressing cannot solve the problem of continuity in clinical practice. Utility Model Content
[0005] This invention provides a combined fixation patch for fixing catheters used in clinical vascular puncture, which combines a traditional catheter fixation patch with a dynamic compression hemostasis device to solve the continuity problem in clinical operation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a combination fixation patch for fixing catheters used in clinical vascular puncture, comprising a venous fixation patch and an arterial fixation patch that can be used together but are independent of each other. Both the venous and arterial fixation patches have an excipient portion in their middle. One side of each patch, surrounding the excipient portion, is an adhesive surface. The other side of the venous fixation patch is covered with a transparent polytetrafluoroethylene (PTFE) film. At least one edge of the venous fixation patch has a cutting and tearing portion. The excipient portion of the arterial fixation patch has an inflatable hemostatic component in its middle. The venous and arterial fixation patches can be used in combination. The transparent PTFE film solves the problem of adhesion when multiple catheters are present. The inflatable hemostatic component in the arterial fixation patch meets the need for priority catheter removal and hemostasis after radial artery puncture.
[0007] Preferably, one side of the arterial fixation patch is provided with a reversible fixation patch. The reversible fixation patch is flipped over and adhered to the skin after the arterial catheter fixed with the arterial fixation patch is removed. By providing a reversible fixation patch, the arterial fixation patch can continue to be firmly adhered and fixed after the catheter is removed, thereby achieving hemostasis.
[0008] Preferably, the pneumatic hemostasis assembly includes an airbag located in the middle of the excipient section and an inflation port connected to the airbag. A one-way valve is installed at the inflation port. The one-way valve can be connected to a standard syringe or a special inflation ball through the inflation port, allowing gas to flow unidirectionally into the airbag and using the airbag to compress and stop the bleeding.
[0009] Preferably, the excipient is a hydrocolloid dressing, which has good adhesion, flexibility and moisture retention.
[0010] Preferably, both the vein fixation patch and the artery fixation patch are provided with writable paper for writing and marking.
[0011] Preferably, the vein fixation patch and the artery fixation patch are different colors to facilitate quick and easy differentiation between them.
[0012] Compared with the prior art, the beneficial effects of this utility model are: With a simple structure, the venous fixation patch and the arterial fixation patch can be used in combination. The transparent polytetrafluoroethylene membrane can solve the problem of patch adhesion when multiple catheters are present. The arterial fixation patch is equipped with an inflatable hemostatic component, which can meet the needs of priority removal and hemostasis after radial artery puncture. It is mainly used for patients who need to perform invasive arterial pressure monitoring and intravenous drug administration during the operation, and for radial artery puncture site compression hemostasis and venous access maintenance after the operation, solving the pain point of continuity in clinical operation.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] This invention aims to address the challenge of maintaining continuity in clinical procedures. For example... Figure 1-3 As shown, the following technical solution is provided: a combination fixation patch for fixing catheters in clinical vascular puncture, comprising a venous fixation patch 1 and an arterial fixation patch 6 that can be used together and are independent of each other. Both the venous fixation patch 1 and the arterial fixation patch 6 have an excipient portion 3 in the middle. One side of both the venous fixation patch 1 and the arterial fixation patch 6 is an adhesive surface surrounding the excipient portion 3. The other side of the venous fixation patch 1 is covered with a transparent polytetrafluoroethylene film 5. At least one edge of the venous fixation patch 1 has a cutting and tearing portion 4. The arterial fixation patch 6 has an inflatable hemostatic component in the middle of the excipient portion 3. The venous fixation patch 1 and the arterial fixation patch 6 can be used in combination. The transparent polytetrafluoroethylene film 5 can solve the problem of adhesion when multiple catheters are present. The arterial fixation patch 6 has an inflatable hemostatic component, which can meet the need for priority catheter removal and hemostasis after radial artery puncture.
[0017] Specifically, both the venous fixation patch 1 and the arterial fixation patch 6 can be used alone. For patients who need to undergo invasive arterial pressure monitoring and intravenous drug administration simultaneously during surgery, the arterial fixation patch 6 can fix the arterial pressure monitoring catheter and apply pressure to the radial artery puncture site for hemostasis after surgery. The venous fixation patch 1 can fix the intravenous drug administration route. When using both, there are two scenarios. Generally, the venous fixation patch 1 is used first. Before puncturing the arterial line, assess whether the puncture site is covered by the edge of the venous fixation patch 1. If it is covered, tear off the corresponding cut and tear-off portion 4 of the venous fixation patch 1. After tearing off the cut and tear-off portion 4, the arterial puncture site can be exposed. If the puncture site is not covered, proceed with the puncture normally. After puncturing the arterial line, fix the venous fixation patch 6. If the cut and tear-off portion 4 is torn off, the venous fixation patch 1 needs to be fixed with the arterial fixation patch 6. The two fixation patches are used in combination.
[0018] The transparent polytetrafluoroethylene membrane 5 has excellent anti-adhesion properties, which can prevent the problem of adhesion of the venous fixation tape when removing the arterial catheter in advance. It can ensure that the venous fixation tape will not be torn, deformed or even fall off, thus protecting the venous access from slipping, folding, leakage, or even the need to remove the venous tape and re-fix it.
[0019] The cutting and tearing section 4 is formed by laser pre-cut dotted lines. If the puncture point is found to be covered by the vein fixation patch 1 in advance during arterial puncture, the corresponding fixation patch can be removed according to needs to fully expose the location of the arterial puncture point and facilitate arterial catheterization.
[0020] When the arterial tube needs to be removed, one side of the arterial fixation patch 6 can be lifted first to remove the arterial tube, and then the arterial fixation patch 6 can be put back on. Then the inflatable hemostatic component can be inflated. The inflatable hemostatic component can compress the puncture point on the skin to stop bleeding.
[0021] In this embodiment, as Figure 2-3 As shown, in order to ensure the firmness of the arterial fixation patch 6 after tube removal, a flip-up fixation patch 7 is provided on one side of the arterial fixation patch 6. The flip-up fixation patch 7 is flipped and adhered to the skin after the arterial catheter fixed by the arterial fixation patch 6 is removed. By setting the flip-up fixation patch 7, the arterial fixation patch 6 can continue to be firmly adhered and fixed after tube removal, thereby achieving hemostasis.
[0022] As a specific embodiment of the pneumatic hemostasis component, the pneumatic hemostasis component includes an air bladder 8 located in the middle of the excipient section 3 and an inflation port 10 connected to the air bladder 8. A one-way valve 9 is installed at the inflation port 10. The one-way valve 9 can be connected to a standard syringe or a special inflation ball through the inflation port 10. Gas flows in one direction to inflate the air bladder 8, and the air bladder 8 is used to compress and stop bleeding. Specifically, before inflation, the air bladder 8 is folded and hidden under the excipient section 3. The one-way valve 9 is a miniature one-way valve, compatible with standard syringes or special inflation balls (similar to endotracheal intubation air bladders). The thickness of the air bladder 8 is ≤2mm when it is not inflated, and its expansion volume is 5-8mL after inflation. The pressure is adjusted by the inflation volume.
[0023] In this embodiment, the excipient part 3 is a hydrocolloid dressing. Hydrocolloid dressings have good adhesion, flexibility and moisturizing properties. Hydrocolloid dressings are usually composed of natural polymer materials such as sodium carboxymethyl cellulose (CMC), gelatin, pectin, as well as elastomers, plasticizers, etc.
[0024] In this embodiment, to mark the vein fixation patch 1 and the artery fixation patch 6, both the vein fixation patch 1 and the artery fixation patch 6 are provided with writable paper 2 for writing and marking. At the same time, the vein fixation patch 1 and the artery fixation patch 6 are different colors for easy and quick differentiation; the vein fixation patch 1 can be light blue, and the artery fixation patch 6 can be light pink.
[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0026] Furthermore, in this utility model, descriptions involving terms such as "primary," "secondary," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "primary" or "secondary" may explicitly or implicitly include at least one of those features. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0028] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
