Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an internal jugular vein hemodialysis catheter fixing device and a disposable fixing product containing the same. Background Art

[0002] like Figure 1 As shown, the internal jugular vein hemodialysis catheter 100 includes a front end tube body 110 and a double-lumen catheter, wherein the double-lumen catheter includes two branches 131, one end of each branch 131 is connected to the front end tube body 110, and the other end of each branch 131 is provided with an enlarged connector 133, each branch 131 is provided with a switch clamp 132, and a sleeve 120 is provided at the connection between the double-lumen catheter and the branch 131, and a connecting portion 121 is provided on both sides of the sleeve 120.

[0003] The aforementioned internal jugular vein hemodialysis catheter 100 is suitable for obtaining long-term or short-term blood supply during treatments such as hemodialysis, plasma filtration, or plasma exchange. It establishes access via the internal jugular, subclavian, and femoral veins. During use, the front end tube body 110 is partially inserted into the patient's blood vessels. To prevent the tube from falling out, the connecting portion 121 is simply sutured to the patient's neck skin to secure the front end tube body 110. A sterile dressing is then applied to cover the catheterization puncture site (i.e., the catheterization port). The internal jugular vein hemodialysis catheter 100 is then taped or tied to the patient's neck or head with tape, securing it above the patient's right clavicle.

[0004] During routine maintenance in clinical practice, the adhesive tape will be applied to the catheter port after disinfection. After the hemodialysis treatment is completed, the double-lumen catheter will be wrapped with gauze in several times, and then fixed to the neck with adhesive tape.

[0005] Double-lumen catheters are more likely to slip than single-lumen catheters, especially hemodialysis catheters in the internal jugular vein. Since there is not enough fixed position on the neck, it is difficult to fix the dialysis line by sticking it with tape or tying it around the patient's neck or head. The poor stability affects dialysis safety. The neck position is more prone to pulling and becoming uncomfortable as the head rotates, which makes the patient uncomfortable. The tail end of the double-lumen catheter is exposed, and poor fixation can also cause the film to curl and loosen, making unplanned extubation prone to occur.

[0006] Therefore, the above-mentioned prior art has at least the following technical problems: the fixing method of the internal jugular vein hemodialysis catheter in the prior art has poor stability, is easy to pull, and is easy to loosen, which affects the dialysis safety, is poor in comfort, and is easy to fall off.

[0034] The embodiment of the present application provides an internal jugular vein hemodialysis catheter fixing device to solve the technical problems in the prior art of internal jugular vein hemodialysis catheter fixing methods, such as poor stability, easy pulling, and easy loosening, which affect dialysis safety, poor comfort, and easy tube detachment.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] like Figure 1 As shown, the internal jugular vein hemodialysis catheter 100 includes a front end tube body 110 and a double-lumen catheter, wherein the front end tube body 110 can be inserted into a human blood vessel through the tube insertion port, and the connecting portion 121 on the front end tube body 110 is sutured and fixed to the patient's skin.

[0037] like Figures 2-3 As shown, one or more embodiments of the present application provide an internal jugular vein hemodialysis catheter fixing device 200, the device 200 comprising:

[0038] The self-adhesive patch 210 has a back surface that can be adhered and fixed to human skin, and the self-adhesive patch 210 includes a first application portion 211 and a second application portion 212 connected to each other, wherein:

[0039] The first application portion 211 can be covered on the front end tube body 110 and adhered to the tube placement port to compress and fix the front end tube body 110; a restraining member for restraining the double-lumen catheter is provided on the front side of the second application portion 212; and the self-adhesive application 210 allows the double-lumen catheter to pass from the back side of the first application portion 211 to the front side of the second application portion 212 to be positioned within the restraining member;

[0040] The ear hook portion 220 has one end for flexible connection with the double-lumen catheter and the other end for fixing on the human ear.

[0041] As can be seen from the above description, the device 200 described in the embodiment of the present application can, after the internal jugular vein hemodialysis catheter 100 is placed in the blood vessel, attach the first application part 211 to the connection between the internal jugular vein hemodialysis catheter 100 and the skin (i.e., the connection part 121 and the patient's skin are sutured), thereby compressing and fixing the front end tube body 110 at the tube placement port; at the same time, by providing a buckle 240 on the front of the second application part 212 to position the double-lumen catheter, instead of directly fixing the double-lumen catheter to the neck skin with tape or a band, it can effectively reduce skin irritation and catheter pressure; in addition, by providing an ear hook part 220, the tail end of the double-lumen catheter is suspended on the ipsilateral auricle to prevent the tail end from being folded, thereby further effectively fixing the double-lumen catheter; and the flexible connection between the ear hook part 220 and the double-lumen catheter can reduce the traction on the catheter and maintain the upright shape of the catheter, thereby improving the safety of the internal jugular vein dialysis circuit and effectively ensuring the dialysis effect. The invention effectively solves the technical problems in the prior art of the internal jugular vein hemodialysis catheter 100, such as poor stability, easy pulling, easy loosening, which affects dialysis safety, poor comfort and easy tube detachment, and achieves the beneficial effects of good fixation effect, high dialysis safety and high comfort in use.

[0042] It should be noted that in the embodiments of the present application, the back side refers to the side that contacts the human skin during use, and the front side refers to the side exposed to the human body during use. The following description is based on the above reference orientation, which will not be elaborated on. However, it should be emphasized that the above orientation or positional relationship limitations are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application.

[0043] like Figure 1 As shown, the double-lumen catheter includes two branches 131, one end of each branch 131 is connected to and communicated with the front end tube body 110, and the other end of each branch 131 is provided with an enlarged connector 133, and each branch 131 is provided with a switch clamp 132.

[0044] like Figures 2-3 As shown, in one embodiment of the present application, the second application portion 212 is separated into two independent halves;

[0045] Each of the half parts is provided with a restraining member to fix the branch pipe 131 respectively;

[0046] Each half is connected to a portion of the first applying portion 211 , and a passage slit 252 is formed between each half and the first applying portion 211 to allow the branch tube 131 to pass from the back of the first applying portion 211 to the front of the half.

[0047] Specifically, using one of the restraining members to fix the branch tubes 131 separately can allow different degrees of offset between the two branch tubes 131, and the overall fixation effect of the internal jugular vein hemodialysis catheter 100 is better and the safety is higher.

[0048] For example, Figure 2 、 3 As shown, the second applying portion 212 is divided into two halves along the split 251 in the middle, and each half is partially connected to the first applying portion 211, and the unconnected portion forms a passage 252 for the branch pipe 131 to pass from the back of the first applying portion 211 to the front of the half.

[0049] Each half is respectively connected to a portion of the first applying portion 211 , and each half can be flipped relative to the first applying portion 211 , thereby facilitating the branch tube 131 to pass from the back of the first applying portion 211 to the front of the half.

[0050] For example, the first applying portion 211 may be rectangular in shape and have a size of 12*10 cm. The second applying portion 212 may also be rectangular in shape and have a size of 6*8 cm.

[0051] like Figures 2-3 As shown, in one embodiment of the present application, the restraining member is a buckle 240 , and a buckle slot is provided on one side of the buckle 240 for the branch pipe 131 to be snapped in or out.

[0052] Specifically, the buckle 240 is used to constrain the branch pipe 131, which is very convenient to insert and remove, and has high efficiency when used. The buckle 240 is about 1*1 cm in size, made of plastic with certain elasticity, and is a one-time semicircular shape.

[0053] Further, such as Figures 2-3 As shown, the two snap-fits 240 have their snap-fit ​​openings facing outwards of the self-adhesive patch 210 , so that they can be snapped into the branch tubes 131 respectively without affecting each other.

[0054] Furthermore, Figure 3 As shown, the buckle 240 is used to clamp the portion of the branch pipe 131 between the connector 133 and the switch clamp 132 . Since the connector 133 and the switch clamp 132 are relatively large in size, the buckle 240 has a better anti-slip effect.

[0055] In one embodiment of the present application, Figures 2-3 As shown, the ear hook portion 220 is connected to the two branches 131 of the double-lumen catheter respectively through an elastic rope 131.

[0056] Specifically, each elastic rope 131 is about 2 to 3 cm long. The elastic rope 131 is elastic and extensible, and can be extended or retracted at will with the patient's neck movement, which can reduce the traction on the internal jugular vein hemodialysis catheter when the patient turns his head, improve the comfort of use, and at the same time maintain the upright shape of the internal jugular vein hemodialysis catheter 100.

[0057] Further, such as Figures 2-3 As shown, one end of the elastic rope 131 is connected to the ear hook 220 , and the other end is provided with an elastic ring 231 that can be looped and fixed on the connector 133 , and the elastic rope 131 is connected to the branch pipe 131 through the elastic ring 231 .

[0058] Specifically, the connector 133 is provided with a thread, and the elastic ring 231 is embedded in the thread to achieve a fixed connection. It can be separated when not in use, which is convenient for replacing the internal jugular vein hemodialysis catheter 100 and repeatedly using the ear hook 220.

[0059] In one embodiment of the present application, Figures 2-3 As shown, the ear-hanging portion 220 is a hook, which can be hung on the ear.

[0060] Specifically, the earphones are fixed with hooks, which makes it easy to hang and take off, and can be reused after being wiped and disinfected with alcohol, thus reducing the cost of use.

[0061] In addition, the hook is flat to reduce pressure on the auricle skin, avoid skin damage, and improve user comfort. The hook is made of silicone, which is skin-friendly and soft, further improving user comfort.

[0062] Furthermore, the self-adhesive dressing 210 comprises, from front to back, a non-woven fabric layer, a waterproof layer (e.g., polyethylene), a foam adhesive layer (e.g., polyurethane foam), and a backing paper layer. After removing the backing paper layer, the dressing can be applied to human skin. The foam adhesive layer contains a foam dressing (polyester foam) that absorbs bleeding or fluid from the catheter port, keeping the puncture site dry.

[0063] The foam adhesive layer can be made of a self-adhesive skin-friendly material to reduce skin irritation and pressure on the catheter. Specifically, the self-adhesive patch 210 can be a mature product in the prior art, which will not be described in detail here.

[0064] The self-adhesive patch 210 and the ear hook 220 included in the internal jugular vein hemodialysis catheter fixing device 200 described in the embodiment of the present application can be packaged together in a plastic bag (a type of packaging bag). After sterilization, it can be used as a disposable sterile fixing product during the maintenance of hemodialysis catheters. It is very convenient and worthy of promotion.
