Description

Technical Field

[0001] This utility model relates to a fixation device used in medicine, specifically a jugular vein artificial hepatic duct fixation device. Background Technology

[0002] The central venous double-lumen catheter for artificial liver is one of the vascular access routes for non-biological artificial liver and other blood purification therapies. Its double-lumen extension tubes merge into a single double-lumen tube at the head, such as... Figure 1 , Figure 2 As shown. A non-biological artificial liver uses an external mechanical device to temporarily replace some of the functions of the human liver, achieving the goal of treating patients with liver failure. The principle is that the external mechanical treatment device is connected to the human body. Driven by a power pump, venous blood is drawn from the patient's central vein and introduced into the extracorporeal circulation tubing of the mechanical device for extracorporeal circulation before returning to the body, thereby clearing various toxins produced by liver failure. Clinically, a double-lumen catheter located in the central vein is used. Part of the double-lumen catheter is inserted into the central vein, while the exposed double-lumen portion is exposed to the skin and consists of a blood outflow end (arterial end) and a blood return end (venous end). Both ends are located at the end of the double-lumen extension tube, and the circulation tubing connects to these two ends. Because the femoral vein significantly impacts the patient's daily life, currently, the double-lumen catheter inserted through the right central cervical vein is more commonly used in clinical practice for non-biological artificial liver treatment. Due to clinical practice and patient conditions, during treatment breaks, sterile dressings are used to secure the exposed double-lumen catheter to the skin. The outer portion of the double-lumen catheter is then wrapped with sterile gauze and secured to the dressing and the patient's skin with tape. Because the double-lumen catheter remains in the patient's neck for several days, and due to gravity, it often sags, causing the sterile dressing to lose its adhesiveness and expose the puncture site, increasing the risk of accidental slippage and infection. Simultaneously, the gauze and tape may also detach due to the curling of the sterile dressing, increasing the workload for medical staff in changing gauze and indirectly increasing the amount of sterile gauze and tape used. Repeated use of tape can also increase patient discomfort and affect treatment compliance. Furthermore, frequent changes of sterile dressings and gauze disrupt the patient's daily rest, unintentionally increasing secondary skin damage and psychological burden. Additionally, the diverse sizes and thicknesses of catheters used in artificial liver treatment further complicate the fixation process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fixing device that can fix the exposed part of the double-lumen catheter during the interval of non-biological artificial liver treatment, increase its fixation and stability after the extension tube is wrapped, thereby reducing accidental slippage, infection and patient discomfort caused by the drooping of the double-lumen catheter.

[0004] To address the above technical issues, this utility model discloses a jugular vein artificial hepatic duct fixation device. The fixation device includes a base plate and an outer fabric. An adhesive layer is provided below the base plate, and a fixing strap with several adjustment holes and a fixing member that can be inserted into the adjustment holes and fixed are provided above the base plate. The outer fabric is located on one side of the base plate, and a wrapping bag is provided above the outer fabric. Adhesive tape is provided on both sides of the outer fabric.

[0005] Furthermore, the adhesive layer includes adhesive and adhesive protective paper, with the adhesive located between the base plate and the adhesive protective paper. The adhesive is made of a material that is harmless to the human body.

[0006] Furthermore, the fastener includes a support column and a button. The support column is cylindrical, with its bottom end connected to the base plate and its top end connected to the button. The adjustment hole is elongated, and the button is hemispherical, with its diameter slightly larger than the width of the adjustment hole. The support column provides support for the button.

[0007] Furthermore, the fastener, the fastening strap, and the base plate are made of silicone material and are integrally molded.

[0008] Furthermore, the outer extension fabric and the base plate are arranged in a T-shape, with the horizontal part of the T being the base plate and the vertical part of the T being the outer extension fabric.

[0009] Furthermore, the package is arched, with the bottom sides of the arch fixedly connected to the outer fabric. One side can also use a snap fastener, Velcro, or strap for an openable connection, making it easier to insert the outer tube into the package. The two ends of the arch are located near the bottom plate and away from the bottom plate, respectively, and both ends are open. The openings at both ends maintain ventilation and cleanliness inside the package, preventing blood clots and other contaminants from accumulating inside and avoiding dampness caused by the patient's sweat, which promotes the growth of pathogens.

[0010] Furthermore, there are three adjustment holes.

[0011] Furthermore, the package is made of natural fiber material.

[0012] Furthermore, the adhesive tape is symmetrically arranged on both sides of the outer epitaxial fabric.

[0013] Furthermore, the tape is a non-woven fabric tape, and a release paper is provided on the back side.

[0014] When using the fixation device of this invention, the base plate is first adhered to the patient's skin, and then the double-lumen tube of the artificial liver tube is fixed to the base plate. This reduces the risk of infection caused by the curling of the sterile dressing due to the sagging of the double-lumen catheter. Since there are several adjustment holes, different diameter catheter tips can be accommodated by inserting the button into different adjustment holes, making it widely applicable and securely fixed. The outer fabric and wrapping bag can wrap the outer tube, avoiding frequent changes due to loose gauze, saving the workload of medical staff, and reducing patient discomfort. This invention is not only applicable to the treatment of non-biological artificial livers, but also to blood purification treatments such as kidney dialysis. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further explained below with reference to the embodiments. The following embodiments are only used to illustrate the present invention, but are not intended to limit the scope of implementation of the present invention.

[0024] Example 1

[0025] This utility model discloses a jugular vein artificial hepatic duct fixation device, such as Figure 3 , Figure 4As shown. The main body of the fixing device is T-shaped, with the horizontal part of the T being the base plate 1 and the vertical part being the outer extension fabric 6. The base plate 1 and the outer extension fabric 6 are generally square in structure.

[0026] An adhesive layer 2 is applied to the underside of the base plate 1. The adhesive layer 2 includes adhesive 2.1 applied to the bottom side of the base plate 1 and adhesive protective paper 2.2 covering the adhesive 2.1.

[0027] A fixing strap 5 and a fixing element are provided on the top of the base plate 1, located on both sides of the center line of the outer extension fabric 6. The fixing strap 5 has several (three in this embodiment) adjustment holes 5.1. The fixing element includes a cylindrical support column 3 and a hemispherical button 4. The bottom end of the support column 3 is connected to the base plate 1, and the top end is connected to the button 4. The adjustment holes 5.1 are elongated, such as rectangular or oblong holes, and the diameter of the button 4 is slightly larger than the width of the adjustment hole 5.1, allowing the button 4 to be securely fixed after being inserted into the adjustment hole 5.1. The fixing element, fixing strap 5, and base plate 1 are made of a single piece of elastic silicone material.

[0028] The outer fabric 6 is symmetrically provided with adhesive tape 8 on both sides, generally two tapes on each side. When the outer fabric is extended, the number of adhesive tapes 8 can be increased appropriately. The adhesive tape 8 is non-woven fabric tape, and there is a release paper on the back of each tape.

[0029] A wrapping bag 7, made of natural fiber material, is provided above the outer fabric 6. The wrapping bag 7 is arched, with the bottom of both sides of the arch fixedly connected to the outer fabric 6. The two ends of the arch are located on the side closer to the bottom plate 1 and the side farther from the bottom plate 1, and both ends of the arch are open.

[0030] The length of the outer fabric 6 and the wrapping bag 7 must be sufficient to accommodate the length of the outer tube 11, and the width must be sufficient to accommodate the stop clip 12 on the outer tube 11. This is to prevent the wrapping bag 7 from being too short or narrow to ensure proper wrapping; that is, the wrapping bag 7 must completely enclose the outer tube 11 (including the stop clip 12). When applicable to straight-tube type double-lumen tubes, the length of the outer fabric 6 and the wrapping bag 7 should be slightly longer, such as... Figure 6 As shown.

[0031] Before using the device of this utility model, first peel off the adhesive protective paper 2.2 under the base plate 1 and the adhesive release paper on the back of the tape 8.

[0032] When fixing the curved double-lumen tube, first straighten the outer tube 11 and pass it through the inside of the wrapping bag 7 on the side away from the base plate 1. Adjust its position so that the connector 10 is located between the fixing strap 5 and the support column 3. Attach the fixing device to the patient's neck, and then insert the button 4 into the adjustment hole 5.1 in the appropriate position to fix it. Then bend the outer tube 11 and insert it into the wrapping bag 7, so that both the stop clip 12 and the connector 12 are located inside the wrapping bag 7. Figure 5 As shown.

[0033] When fixing the straight-tube double-lumen tube, first insert the extended tube 11 into the wrapping bag 7 from the side closest to the base plate 1, ensuring that the stop clip 12 and connector 12 are both inside the wrapping bag 7. Adjust the position so that the connector 10 is positioned between the fixing strap 5 and the support post 3. Attach the fixing device to the patient's neck, and then snap the button 4 into the adjustment hole 5.1 in the appropriate position to secure it. At this point, the tube body 9 is located on the side of the base plate 1 furthest from the wrapping bag 7. Figure 7 As shown.
