Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an integrated umbilical arteriovenous catheter fixing patch. Background Art

[0002] In the clinical care of newborns, umbilical vein catheterization and umbilical artery catheterization are often used to administer medication. This method can effectively avoid repeated punctures in children and alleviate their pain, but it also brings about the problem of fixation of the umbilical arteriovenous catheter.

[0003] At present, the bypass method is often used in clinical practice to fix the exposed umbilical arteriovenous catheter. The bypass method fixes the umbilical arteriovenous catheter directly at the umbilical part of the child, which is complicated to operate and has poor fixation effect. The shortcomings of the bypass method for fixing the umbilical arteriovenous catheter are mainly reflected in the following aspects:

[0004] 1. Poor fixation effect, the catheter is easy to fall off. There are few fixation points, and only simple adhesive tape is used. The catheter is directly exposed, and the adhesive tape is easy to get wet and loose. The catheter is easy to be torn off when the child turns sideways or turns over, or when the nurse is caring for the child; it is also not appropriate to use only transparent film dressings for fixation. The adhesive on the transparent dressing is very sticky and irritating to the child's skin, which can easily damage the child's delicate skin.

[0005] 2. The catheter is easily compressed. The umbilical arteriovenous catheter fixed by the bypass method is placed at the umbilical part. The umbilical part is protruding and the catheter is suspended in the air. When the child turns sideways or rolls over, the catheter is easily compressed, affecting the flow of fluid in the catheter and thus affecting the child's treatment.

[0006] 3. Difficult to read and easy to pull out by mistake. During the treatment of children, the flow of liquid in the catheter needs to be observed and recorded, and the readings on the catheter need to be read frequently. The catheter itself has a small diameter, and the scale is printed on the catheter. The catheter fixed by the bypass method is in a suspended state, and the surrounding fixing threads used to fix the catheter are relatively messy. These factors make the catheter difficult to observe and read, and it is easy to pull out by mistake when part of the catheter needs to be removed, increasing the risk of unplanned extubation.

[0007] 4. The exposed part of the catheter is easily contaminated. The umbilical artery and vein tube placed by the bypass method is located in the navel, close to the child's genitals. The exposed catheter and its fixing device are easily contaminated by the child's excrement.

[0008] 5. Poor comfort for children. When using the bypass method, there is too much excess catheter, which can easily cause pressure sores when turning over. If a fixing plate or adhesive plate is used to fix the catheter, it is easy to damage the skin or cause pressure sores due to the hardness of the fixing plate or adhesive plate, causing discomfort to the child. Utility Model Content

[0009] In view of the technical problems existing in the prior art, the purpose of the utility model is to provide an integrated umbilical arteriovenous catheter fixing patch with good fixing effect, simple structure and high comfort.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] The integrated umbilical arteriovenous catheter fixing patch includes a base and a covering film; the base is made of a hydrocolloid dressing, including a bottom surface and a catheter placement surface; the bottom surface is used to be attached to the human skin surface; the catheter placement surface is used to place the catheter; at least four entry and exit buckles are provided on the catheter placement surface, and the entry and exit buckles are fixedly connected to the base; the covering film is made of a transparent film dressing, including an adhesive surface; the adhesive surface covers the catheter and adheres to the catheter placement surface. With this structure, the fixing patch has a simple structure, can well fix the catheter, is easy to read, and can also improve the comfort of umbilical arteriovenous catheterization. The entry and exit buckles in the fixing patch are used to fix the part of the catheter that goes in or out of the fixing patch. Two entry and exit buckles can fix one catheter. The design of the entry and exit buckles can not only fix multiple catheters, but also provide certain support to the catheter to prevent the catheter from being compressed by external force and affecting the flow of liquid in the catheter. Both the entry and exit buckles and the coating can fix the catheter, with many fixing points and good fixing effect; if the catheter is facing up with the scaled side facing up and fixed with a transparent coating, easy reading can be achieved; the fixing patch does not use silk thread to fix the catheter, which is convenient for distinguishing different catheters, avoiding accidental extraction, and reducing the risk of unplanned extraction; the base body is made of soft and skin-friendly hydrocolloid dressing, and the coating is made of soft transparent dressing. The catheter is fixed to the surface of human skin through the base body by the coating, which is highly comfortable and can protect the patient's skin and avoid skin surface damage or pressure sores.

[0012] As a preferred embodiment, a plurality of wire-winding buckles are also provided on the tube placement surface; the wire-winding buckles are fixedly connected to the base body and used to fix the catheter wrapped around the tube placement surface. With this structure, the catheter wrapped around the tube placement surface can be better fixed, which is convenient for reading.

[0013] As a preferred embodiment, the access buckle and / or the wire winding buckle are provided with an arc-shaped groove matching the size of the catheter, and the opening width of the arc-shaped groove is smaller than the diameter of the catheter. With this structure, the catheter can be engaged with the access buckle or the wire winding buckle in just one step, which can be operated with one hand, is stable and convenient.

[0014] As a preferred embodiment, the tube placement surface is provided with a guiding structure, which is used to guide the tube winding operation. With this structure, it is convenient for the operator to fix the catheter.

[0015] As a preferred embodiment, the guide structure includes a plurality of concentric guide grooves or guide protrusions in annular shape. With this structure, the operator can consciously separate the catheters during the nursing operation to reduce the crossing and overlapping of the catheters, making it convenient to observe the flow of the liquid in the catheter and to read the value of the scale on the catheter.

[0016] As a preferred embodiment, the catheter placement surface is also provided with a support column, which is arranged at the center of the guide structure. With this structure, the catheter can be better supported. After the catheter is fixed with a fixing patch, if there is no structure that can support the catheter at the center of the catheter surrounding the catheter placement surface, when this place is compressed, it will affect the flow of liquid in the catheter at the center of the guide structure. Therefore, the design of the support column can better protect the catheter and prevent the catheter from being compressed.

[0017] As a preferred embodiment, the tube placement surface is also provided with a supporting boss, which surrounds the guide structure. With this structure, the catheter near the edge of the fixing patch is easily compressed by external force.

[0018] As a preferred embodiment, the support boss is provided with a plurality of channels for the catheter to enter and exit; the entry and exit buckles are arranged at the channels and / or the edge of the base. With this structure, the support boss will not cause the catheter on the catheter placement surface to protrude, and will not affect the flow of liquid in the catheter; the entry and exit buckles are arranged at the channels and / or the edge of the base, which can not only make the catheter placement operation more convenient, but also enhance the supporting and protective effect of the fixing patch on the catheter.

[0019] As a preferred embodiment, the size of the film is smaller than the size of the base. With this structure, it is more convenient to fix the catheter. One side of the film is more sticky. If it is large, it is easy to stick to itself or stick to the skin surface of the operator or user, affecting the operation. If it cannot be torn off, it may even require replacement of the fixing patch. Therefore, a smaller film is more convenient to fix the catheter.

[0020] As a preferred embodiment, the adhesive surface includes a connection area and an adhesive area, the connection area is fixedly connected to the base body as a whole, and the adhesive area is used to adhere and fix the catheter to the base body. With this structure, the coating and the base body are integrated, and the operation of fixing the catheter is simpler and less prone to error.

[0021] In general, the utility model has the following advantages: good catheter fixing effect, convenient operation, high comfort, and the catheter is not easily compressed or contaminated. BRIEF DESCRIPTION OF THE DRAWINGS
