Description

Technical Field

[0001] This utility model relates to the field of medical indwelling catheter care devices, specifically to an internal jugular vein catheter fixation device. Background Technology

[0002] Internal jugular vein catheterization is widely used in clinical transfusion, total parenteral nutrition, central venous pressure monitoring, and hemodialysis due to its long indwelling time, simple operation, wide range of infusion types, good catheter elasticity, and ability to establish safe, rapid, and reliable vascular access in a short time. Internal jugular vein catheterization is generally a Y-shaped double-lumen central venous catheter, consisting of a connecting catheter and two side tubes. The lower end of the catheter is inserted through the neck skin into the internal jugular vein and extends within the vessel. A fixing wing is located at the upper part of the catheter, near the skin exit point. The two side tubes are exposed and need to be secured to prolong the catheter's indwelling time and reduce the rate of unplanned extubation.

[0003] Currently, the common method for fixing internal jugular vein catheters involves suturing the fixation wings to the skin, securing the catheter and side tubes near the puncture site with sterile dressings, and using medical elastic tape to secure the two side tubes further away from the puncture site. However, because the two side tubes are directly attached to the neck skin with medical elastic tape, they are in direct contact with the skin. This can easily lead to pressure sores on the skin if the internal jugular vein catheter is left in place for an extended period. Furthermore, since the exposed portion of the internal jugular vein catheter is relatively long, and the medical elastic tape is applied perpendicularly to the side tubes, a large amount of tape is needed to ensure a stable fixation, which is time-consuming, labor-intensive, and increases the workload of medical staff. Therefore, the fixation devices used in current methods for fixing internal jugular vein catheters need improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned above and provide an internal jugular vein catheter fixation device that can quickly and conveniently fix the entire internal jugular vein catheter while also preventing pressure damage to the skin caused by the exposed side tube of the internal jugular vein catheter.

[0005] This utility model achieves its utility model objective by adopting the following technical solution: an internal jugular vein catheterization fixation device, comprising a sterile dressing and a fixation component, wherein the fixation component comprises a fixation pad and a fixation member, the sterile dressing and the fixation pad are arranged in a "T" shape, the bottom surface of the sterile dressing and the fixation pad is provided with an adhesive surface, and release paper is covered on the adhesive surface; at least one of the fixation members is fixedly installed on the top surface of the fixation pad, and the fixation member is used to fix the two side tubes of the internal jugular vein catheterization.

[0006] Furthermore, the sterile dressing is made of a transparent material, and an absorbent pad is fixed in the center of the adhesive surface of the sterile dressing.

[0007] Furthermore, the sterile dressing and the fixation pad are separated, or the sterile dressing and the fixation pad are fixedly connected at one end, and a tubing channel for internal jugular vein catheterization is provided at the connection between the sterile dressing and the fixation pad.

[0008] Preferably, the sterile dressing is square with its four corners rounded.

[0009] Preferably, the fixing pad is a pad layer made of flexible material, the bottom surface of the flexible pad layer is provided with an adhesive surface, and release paper is covered on the adhesive surface.

[0010] Furthermore, the fixing component includes a base plate and two side-by-side fixing buckles fixed to the top surface of the base plate. The base plate is fixedly connected to the fixing pad. The fixing buckle includes an elastic C-shaped buckle with the opening facing upward and the C-shaped buckle fixedly connected to the base plate. The inside of the C-shaped buckle is a clamping cavity communicating with the opening. The width of the opening is smaller than the outer diameter of the side tube of the internal jugular vein catheter. The inner diameter of the clamping cavity is smaller than or equal to the outer diameter of the side tube of the internal jugular vein catheter, which is greater than the width of the opening.

[0011] Furthermore, extension plates are fixedly connected to both sides of the opening of the C-shaped buckle, and the two extension plates are arranged in a V-shape with the opening facing upwards.

[0012] Preferably, a rubber pad or silicone pad is fixedly laid on the inner wall of the C-shaped buckle.

[0013] Furthermore, the fixing component also includes an elastic fixing strap, the two ends of which are respectively fixedly connected to the end of the fixing pad away from the sterile dressing. The fixing strap is a single piece, or there are two fixing straps, one end of which is fixedly connected to the fixing pad, and the other ends of which are connected by a detachable connecting component, which is a combination of Velcro or buttons and buttonholes.

[0014] Furthermore, the area of ​​the bottom surface of the fixing pad near the sterile dressing is the adhesive area with an adhesive surface, and the area away from the sterile dressing is the non-adhesive area without an adhesive surface.

[0015] By adopting the above technical solutions, this utility model has achieved its utility model objectives well. This internal jugular vein catheter fixation device is fixed and pasted near the puncture point with a sterile dressing to fix the catheter and side tube near the puncture point. The fixation pad is fixed and pasted on the patient's neck, and the side tube can be placed on the top surface of the fixation pad to avoid direct contact between the side tube and the skin.

[0022] Detailed Implementation

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. The content of the utility model will be further explained below in conjunction with the drawings:

[0024] Example 1

[0025] Refer to the instruction manual appendix Figure 1A jugular vein catheter fixation device includes a sterile dressing 1, a fixation pad 2, and a fixation element 3. The sterile dressing 1 and the fixation pad 2 are arranged in a "T" shape, that is, the fixation pad 2 is perpendicular to the sterile dressing 1. The bottom surface of the sterile dressing 1 and the fixation pad 2 is provided with an adhesive surface, and release paper is covered on the adhesive surface. The sterile dressing 1 and the fixation pad 2 can be adhered and fixed to the patient's neck through the adhesive surface. Specifically, the sterile dressing 1 covers and fixes the catheter and the side tube near the puncture point. The fixation pad 2 can be fixedly adhered to the skin of the neck at the bottom of the side tube, which can avoid direct contact between the side tube and the skin and can prevent pressure injury to the skin caused by the exposed side tube of the internal jugular vein catheter to a certain extent. Two fasteners 3 are fixedly installed on the top surface of the fixation pad 2. The fasteners 3 are used to fix the two side tubes of the internal jugular vein catheter. One fastener 3 is located in the middle of the fixation pad 2 to fix the middle of the two side tubes. The other fastener 3 is located at the end of the fixation pad 2 away from the sterile dressing 1 to fix the end of the two side tubes.

[0026] In one embodiment, the sterile dressing 1 is made of a transparent material, which allows for easy observation of the position of the internal jugular vein catheter and the condition of the skin near the puncture site. An absorbent pad 11 is fixed in the center of the adhesive surface of the sterile dressing 1. The absorbent pad 11 is made of materials such as cotton fiber, non-woven fabric, and sterile gauze cotton. When in use, the absorbent pad 11 covers the puncture site and plays the role of compression hemostasis and absorption of exudate.

[0027] The sterile dressing 1 and the fixation pad 2 are arranged in a "T" shape. The sterile dressing 1 and the fixation pad 2 can be a separate structure (separate) or an integrated structure (connected). Specifically, when the sterile dressing 1 and the fixation pad 2 are separate structures, the sterile dressing 1 and the fixation pad 2 are two separate parts. When in use, the sterile dressing 1 is first covered and fixed to the catheter and the side tube near the puncture point. Then, one end of the fixation pad 2 is placed close to the sterile dressing 1 and fixed to the neck skin at the bottom of the side tube, so that the side tube is on the top surface of the fixation pad 2.

[0028] See attached document Figure 1 , 3 When the sterile dressing 1 and the fixation pad 2 are an integral structure, the sterile dressing 1 and the fixation pad 2 are fixedly connected at one end. A tubing channel 12 for internal jugular vein catheterization is provided at the connection between the sterile dressing 1 and the fixation pad 2. The tubing channel 12 is opened on the fixation pad 2 or the sterile dressing 1. In use, the internal jugular vein catheter is first passed through the tubing channel 12, so that the side tube is on the top surface of the fixation pad 2. Then, the sterile dressing 1 is covered and fixed to the catheter and side tube near the puncture point. Finally, the fixation pad 2 is fixedly attached to the skin of the neck.

[0029] In comparison, when the sterile dressing 1 and the fixing pad 2 are integrated into one piece, it is more convenient to use and more efficient.

[0030] In a preferred embodiment, refer to the appendix. Figure 1 The sterile dressing 1 is square, with its four corners having arc transitions. Arc transitions are less likely to curl up compared to right-angle transitions.

[0031] In a preferred embodiment, the fixation pad 2 is a pad made of a flexible material, and the bottom surface of the flexible pad is provided with an adhesive surface, on which release paper is covered; specifically, the fixation pad 2 is a hydrocolloid dressing, a foam dressing, a hydrogel dressing, or a silver ion dressing; inserting the fixation pad 2 between the side tube and the skin can, to a certain extent, prevent the exposed side tube of the internal jugular vein from causing pressure damage to the skin.

[0032] See attached document Figure 2 The fixing component 3 includes a base plate 32 and two parallel fixing buckles 31 fixed to the top surface of the base plate 32. The base plate 32 is fixedly connected to the fixing pad 2 (which can be fixed by adhesive). The fixing buckle 31 includes an elastic C-shaped buckle 311. The opening of the C-shaped buckle 311 faces upward and the bottom of the C-shaped buckle 311 is fixedly connected to the base plate 32 (which can be fixed by adhesive). The inside of the C-shaped buckle 311 is a clamping cavity 312 that communicates with the opening. The width of the opening is smaller than the outer diameter of the side tube of the internal jugular vein catheter. The inner diameter of the clamping cavity 312 is smaller than or equal to the outer diameter of the side tube of the internal jugular vein catheter, which is greater than the width of the opening. By inserting the side tube into the clamping cavity 312 through the opening of the C-shaped buckle 311, the side tube is clamped and fixed by the elasticity of the C-shaped buckle 311.

[0033] See attached document Figure 2 An extension plate 313 is fixedly connected to both sides of the opening of the C-shaped buckle 311. The two extension plates 313 are arranged in a V-shape with the opening facing upward, so that the opening of the C-shaped buckle 311 forms a V-shaped inlet, which makes it easy for the side tube to enter the clamping cavity 312 from the V-shaped inlet. At the same time, when it is necessary to remove the side tube from the fixed buckle 31, the extension plate 313 can easily open the opening of the C-shaped buckle 311.

[0034] In a preferred embodiment, a rubber pad or silicone pad is fixedly laid on the inner wall of the C-shaped buckle 311 to increase the friction between the side tube and the inner wall of the C-shaped buckle 311, and the elasticity of the C-shaped buckle 311 makes the fixing effect better.

[0035] In this embodiment, the method of using the internal jugular vein catheter fixation device is as follows: After the internal jugular vein catheter is inserted into place, first suture and fix the fixing wings on the catheter to the skin near the puncture site, then remove the release paper from the bottom of the sterile dressing 1, cover the puncture site with the absorbent pad 11 and stick and fix the sterile dressing 1, pass the side tube of the internal jugular vein catheter through the tubing channel 12, then remove the release paper from the bottom of the fixation pad 2, stick and fix the fixation pad 2 to the patient's neck skin, and fix the side tubes to the fixation buckles 31 respectively.

[0036] Example 2

[0037] The inventors discovered that when the internal jugular vein catheter is fixed using the fixation device in Example 1, the increased weight of the end of the side tube due to its connection to a heparin cap or positive pressure connector poses a challenge to the adhesion of the fixation pad 2 away from the sterile dressing 1. This is particularly noticeable when the end of the side tube is connected to external tubing, potentially causing the end of the fixation pad 2 away from the sterile dressing 1 to detach from the skin, gradually leading to the complete detachment of the fixation pad 2 and its eventual failure to secure the side tube. Therefore, to address the above problems...

[0038] See attached document Figure 4 The internal jugular vein catheterization and fixation device also includes an elastic fixation strap 4, with both ends of the fixation strap 4 fixedly connected to the end of the fixation pad 2 away from the sterile dressing 1. The fixation strap 4 is a single piece, or there are two fixation straps 4.

[0039] When the fixation strap 4 is a single piece, it is directly placed over the head and tightened by the elastic band. When there are two fixation straps 4, the other ends of the two fixation straps 4 are connected by a combination of Velcro or buttons and buttonholes, so that the fixation strap 4 is tightened on the patient's head. By fixing the fixation strap 4 to the patient's head, the end of the fixation pad 2 away from the sterile dressing 1 is fixed by the fixation strap 4, which can prevent the end of the fixation pad 2 away from the sterile dressing 1 from detaching from the skin, so that the fixation pad 2 is always stably fixed on the patient's neck skin.

[0040] Because the exposed portion of the internal jugular vein catheter is relatively long, the tip of the side catheter needs to extend behind the ear. Therefore, the fixing pad 2 also needs to extend into the area behind the ear. However, this area contains hair. If the fixing pad 2 is directly attached to the hair, the adhesion will be insufficient, and the pad 2 will pull on the hair, causing pain to the patient. Therefore, to address these issues...

[0041] See attached document Figure 5The area of ​​the bottom surface of the fixing pad 2 near the sterile dressing 1 is the adhesive area 21 with an adhesive surface, and the area away from the sterile dressing 1 is the non-adhesive area 22 without an adhesive surface. The area of ​​the fixing pad 2 near the sterile dressing 1 is fixed to the patient's neck skin by the adhesive area 21 with an adhesive surface, while the area away from the sterile dressing 1 is fixed to the patient's neck skin by the fixing strap 4. The fixing is stable and will not stick the fixing pad 2 to the patient's hair.

[0042] In this embodiment, the method of using the internal jugular vein catheter fixation device is as follows: After the internal jugular vein catheter is inserted into place, first suture and fix the fixing wings on the catheter to the skin near the puncture site, then remove the release paper from the bottom of the sterile dressing 1, cover the puncture site with the absorbent pad 11 and stick and fix the sterile dressing 1, pass the side tube of the internal jugular vein catheter through the tubing channel 12, then remove the release paper from the bottom of the fixation pad 2, stick and fix the fixation pad 2 to the patient's neck skin, then fix the fixation strap 4 to the patient's head, so that the fixation pad 2 fits the patient's neck skin as a whole, and fix the side tubes to the fixation buckles 31 respectively.

[0043] Obviously, modifications and / or additions can be made to the above-mentioned internal jugular vein catheterization and fixation device and corresponding method without departing from the field and scope of this utility model.

[0044] It is equally clear that, although this utility model has described the internal jugular vein catheterization and fixation device in detail, those skilled in the art will certainly be able to obtain many other equivalent forms of internal jugular vein catheterization and fixation devices and corresponding methods that have the features described in the claims and are therefore within the scope of protection defined herein.
