Abstract
Description
Technical Field
[0001] The utility model belongs to medical equipment, and in particular relates to a central venous catheter dressing. Background Art
[0002] Central venous catheter is a silicone or PVC tube placed in the superior and inferior vena cava of the human body to establish an effective infusion route. It has been widely used clinically due to its convenient operation, long retention time, and wide range of infusion types. The application of central venous catheter plays an important role in the fixation of central venous catheter.
[0003] At present, in clinical practice, most central venous catheter dressings are in the form of ordinary dressings such as gauze dressings or transparent dressings to cover the central venous puncture point and the subsequent part of the catheter. However, in actual use, such ordinary dressings have the following disadvantages: 1. The dressing is as thin as paper, and there is no other fixing measure except its own viscosity, which easily leads to curling and poor fixation. 2. The dressing is flat and has insufficient viscosity, so the puncture point is easy to form a hollow and offset, and cannot be firmly fixed in the center of the dressing. 3. Since most central venous catheters are used for indwelling in the neck and subclavian area, and the skin of the neck is wrinkled, the dressing is too thin and has no support point, which makes the central venous catheter easy to fold and twist in the dressing, causing poor infusion. In addition, the plastics such as the Xerox buckle currently on the market are not suitable for the neck, subclavian and other parts where central venous catheters are indwelled due to their large size and hard material. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a central venous catheter dressing, which can better achieve the firm fixation of the central venous catheter and reduce the problem of folding and twisting of the central venous catheter.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A central venous catheter dressing comprises a dressing body, the lower surface of which is a glue surface and covers the puncture point of the central venous catheter and the rear part of the catheter, and also comprises a positioning patch, a double-sided sponge adhesive and a fixing belt. The edge of the dressing body is provided with a V-shaped opening for the catheter to pass through inwardly, the lower surface of the positioning patch is a glue surface and is horizontally adhered to the V-shaped opening position behind the catheter passing through position and is bonded to the upper surface of the dressing body on both sides of the V-shaped opening; the lower surface of the double-sided sponge adhesive is longitudinally adhered to the upper surface of the positioning patch, and the catheter passing through part is arranged along the double-sided sponge adhesive and is adhered to the upper surface of the double-sided sponge adhesive; the middle part of the fixing belt is fixed on the upper surface of the positioning patch, the two ends of the fixing belt are respectively located on the two sides of the double-sided sponge adhesive and the upper surface is provided with Velcro, the two ends of the upper surface of the positioning patch are also provided with corresponding Velcro, the two ends of the fixing belt are relatively flipped and cross-covered on the catheter located on the double-sided sponge adhesive and are respectively fixed to the upper surface of the positioning patch on the opposite side by Velcro.
[0007] One of the two ends of the fixing belt is provided with a through hole for the other end to pass through, and the fixing belt that is flipped over relatively is passed through the through hole of the other end by one end to form the cross.
[0008] The dressing body is made of medical breathable material.
[0009] The middle portion of the fixing belt is sewed and fixed to the middle portion of the upper surface of the positioning patch.
[0010] The Velcro on both ends of the fixing belt is a hook surface, and the Velcro on the upper surface of the positioning patch is a corresponding fleece surface.
[0011] The central venous catheter dressing of the utility model has the following advantages:
[0012] 1. The dressing body is fixed with double-sided sponge adhesive at the front and back, and the double-sided sponge adhesive is fixed with Velcro at the top and bottom. Multiple fixations can effectively avoid loose fixation of the dressing curling edge.
[0013] 2. The V-shaped opening is used for the catheter to pass through and the upper layer of double-sided sponge adhesive is used for fixation, which can ensure that the catheter can be fixed at the designated position with the puncture point as the center during use.
[0014] 3. Place the catheter outside the dressing body. The positioning patch and the positioning piece are made of Velcro material with moderate hardness, which can provide a support point for the catheter to prevent the catheter from folding and twisting when the patient moves, causing problems such as poor infusion.
[0015] 4. The entire dressing operation is simple. After becoming familiar with it, the medical staff will take no more than one minute to complete the entire dressing operation. It is also convenient to adjust the position of the exposed catheter, which can protect the skin from secondary tearing and sticking. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The central venous catheter of the utility model is applied as follows Figure 1 to Figure 3 As shown, compared with the prior art, it also includes an applicator body 1. The applicator body 1 preferably adopts a square structure, but it can also adopt a circular shape, and is made of medical breathable material. Its lower surface is an adhesive surface and covers the puncture point 3 of the central venous catheter 2 and the rear part of the catheter 2. Different from the prior art, it also includes a positioning patch 4, a double-sided sponge adhesive 5 and a fixing belt 6. The edge of the applicator body 1 is provided with a V-shaped opening 7 for the catheter 2 to pass through. The inward length of the V-shaped opening 7 is usually no more than one-third of the length of the applicator body 1. The lower surface of the positioning patch 4 is an adhesive surface and is horizontally adhered to the V-shaped opening 7 behind the position where the catheter 2 passes through and is bonded to the upper surface of the applicator body 1 on both sides of the V-shaped opening 7; the lower surface of the double-sided sponge adhesive 5 is longitudinally adhered to the upper surface of the positioning patch 4, and the length of the double-sided sponge adhesive 5 is the same as the width of the positioning patch 4. The upper surface of the double-sided sponge adhesive 5 may have an easy-to-lift paper (not shown in the figure), and the easy-to-lift paper is torn off to expose the adhesive surface of the upper surface, so that the catheter 2 can be arranged along the direction of the double-sided sponge adhesive 5 and pasted on the adhesive surface of the upper surface of the double-sided sponge adhesive 5; the middle part of the fixing belt 6 is fixed on the upper surface of the positioning patch 4, and the body 1 of the fixing belt 6 and the body 1 of the positioning patch 4 can be made of the same material (such as the material of the existing Velcro tape body, etc.), and the fixing belt 6 can be fixed in a pre-sewn integrated manner. Of course, the fixing belt 6 can also be sewn with the positioning patch 4 by one on each side. The two ends of the fixing belt 6 are respectively located on both sides of the double-sided sponge adhesive 5 and the upper surface is provided with Velcro, and the two ends of the upper surface of the positioning patch 4 also have corresponding Velcro, and the two ends of the fixing belt 6 are relatively flipped and cross-covered on the catheter 2 located on the double-sided sponge adhesive 5 and are respectively fixed to the upper surface of the positioning patch 4 on the opposite side by Velcro.
[0021] As an embodiment, one of the two ends of the fixing belt 6 is provided with a through hole 8 for the other end to pass through, and the relatively flipped fixing belt 6 passes one end through the through hole 8 of the other end to form the cross, and after being tightened and bonded, the fixing effect is better.
[0022] As an embodiment, the Velcro at both ends of the fixing belt 6 is a hook surface, and the Velcro on the upper surface of the positioning patch 4 is a corresponding fleece surface. Of course, the hook surface and fleece surface of the two can be interchanged.
[0023] The operation process of applying the patch of the utility model is as follows:
[0024] In the first step, the dressing body 1 is firstly pasted on the puncture point 3 of the patient's central venous catheter 2, and covers the rear part of the catheter 2, and performs the first fixation, and the remaining catheter 2 is passed through the V-shaped opening 7;
[0025] The second step is to stick the positioning patch 4 horizontally on the V-shaped opening 7 behind the position where the catheter 2 passes through and to adhere to the upper surface of the dressing body 1 on both sides of the V-shaped opening 7;
[0026] The third step is to stick the double-sided sponge glue 5 on the positioning patch 4 longitudinally. Of course, the double-sided sponge glue 5 can also be stuck according to the actual direction of the catheter 2. Then tear off the easy-to-release paper on the upper surface of the double-sided sponge glue 5. Figure 2 ;
[0027] Step 4: Paste the protruding catheter 2 along the direction of the double-sided sponge adhesive 5 onto the upper surface of the double-sided sponge for a second fixation;
[0028] In the fifth step, the two ends of the fixing belt 6 are flipped relative to each other and one end is passed through the perforation 8 to tighten the catheter 2, and then they are pasted on the positioning patch 4 on the corresponding side through Velcro to achieve the third fixation, so as to complete the firm fixation of the central venous catheter 2.
[0029] In summary, by adopting the dressing of the utility model, through the dressing body 1 with the V-shaped opening 7, the catheter 2 can pass through the V-shaped opening 7, the length of the dressing body 1 covering the catheter 2 is reduced, and its edge is not affected by the catheter 2, which is conducive to reducing the edge being not firmly adhered due to the influence of the catheter 2, the puncture point 3 being hollowed out and offset, and not being able to be firmly fixed to the center position of the dressing; the catheter 2 is fixed again by sponge glue, so that the catheter 2 is located in the center position without displacement, ensuring that the catheter 2 is not twisted, and the direction of the catheter 2 can be controlled according to actual needs; the fixing effect of the catheter 2 is further increased by wrapping the two ends of the fixing belt 6, and the upper and lower cooperation with the positioning patch 4 can provide a support point for the catheter 2, which can effectively prevent the catheter 2 from being easily folded and twisted when the patient moves, causing poor infusion.
