Description

Technical Field

[0001] The utility model relates to the technical field of medical care, in particular to a sterile dressing for a peripheral venous indwelling needle. Background Art

[0002] A peripheral intravenous catheter, or PIVC for short, is a medical device used to establish a temporary channel in a peripheral vein. It usually consists of a soft plastic tube and a sharp needle. The use of a peripheral intravenous catheter has the following advantages and applications: Intravenous infusion: A peripheral intravenous catheter can be used for intravenous infusion to deliver drugs, fluids, etc. directly into the patient's blood circulation system. This is one of the most common and commonly used applications, and can provide fast and effective drug administration and fluid supplementation. Long-term venous access: A peripheral intravenous catheter can also be used as a longer-term venous access to facilitate continuous infusion, nutritional support, blood transfusion and other treatments. It can provide convenience when patients need continuous or regular treatment, maintenance, chemotherapy, etc.

[0003] A peripheral venous catheter can be left in place for 72 to 96 hours or even longer if there is no blockage and phlebitis. However, clinically, up to 35% to 50% of catheters have a service life of less than 72 hours. This phenomenon not only increases the number of venous punctures and the incidence of phlebitis, but also increases the pain and economic burden of patients. There are many reasons for the shortened retention time of catheters. One important factor is that the catheter is not firmly fixed, resulting in accidental displacement or detachment. Among them, an improved new type of catheter patch has been invented in the prior art. Considering the problem that traditional transparent patches are easy to curl and tear off, cloth tape is added to the periphery of the patch, and more attention is paid to the fixation of the catheter seat. However, the tape fixing patch at the upper end of the patch does not take into account the compressive effect of the catheter extension tube on the skin, and there is still a problem that the extension tube is easy to fall off due to sweating. Therefore, there are certain disadvantages. Utility Model Content

[0039] The second fixing component 6 is arranged on the first fixing component 5 and is used for sticking the indwelling needle extension tube.

[0040] By providing an easy-to-tear layer 1 and a fixing patch 2, the needle tip of the peripheral venous indwelling needle can be fixed and limited to avoid displacement. At the same time, a connecting layer 3, a non-woven fabric layer 4, a first fixing component 5 and a second fixing component 6 are also provided. First, the fixed indwelling needle extension tube is pasted and fixed by the second fixing component 6, and then the fixed indwelling needle extension tube is pasted to the non-woven fabric layer 4 by the first fixing component 5, so as to further limit and fix the fixed indwelling needle extension tube, which helps to ensure that the indwelling needle is in the correct position and remains stable, avoiding unnecessary movement and shaking, and at the same time can reduce further pressure on the skin, reduce the patient's discomfort and reduce the risk of skin damage, and the patient can move more freely without worrying about the position of the indwelling needle changing or causing discomfort

[0041] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 As shown; the surface area of ​​the fixing patch 2 is smaller than the surface area of ​​the easy-tear layer 1. By further limiting the fixing patch 2 and the easy-tear layer 1, part of the easy-tear layer 1 can be exposed on the outside of the fixing patch 2, thereby facilitating tearing off the easy-tear layer 1 and sticking the fixing patch 2 to the vicinity of the needle tip of the peripheral venous indwelling needle.

[0042] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 As shown; an exposed hole is processed at the center position of the fixing patch 2, wherein a transparent dressing 7 is arranged in the exposed hole, and the transparent dressing 7 and the fixing patch 2 are integrally formed, wherein the surface of the transparent dressing 7 close to the tearable layer 1 is sticky, and when fixing the needle tip of the peripheral venous indwelling needle, it can also be adhered to its outside, and at the same time, the transparent dressing 7 can be connected to the fixing patch 2 by pasting or sewing, so that it is an integrally formed arrangement.

[0043] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 As shown; a writing layer 8 is pasted on the edge of the fixed patch 2. By providing the writing layer 8, the patient information and the use period of the solid patch can be noted on the writing layer 8 during daily care.

[0044] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; the first fixing assembly 5 comprises:

[0045] The first adhesive layer 51 is disposed on the non-woven fabric layer 4 and can be adhered to the non-woven fabric layer 4;

[0046] A through hole 52 is provided at the edge of the first adhesive layer 51; and

[0047] The second adhesive layer 53 is arranged on the non-woven fabric layer 4, which can pass through the through hole 52 and adhere to the non-woven fabric layer 4. The first adhesive layer 51 and the second adhesive layer 53 are both provided with objects similar to Velcro hooks on one side of the surface, which can adhere to the non-woven fabric layer 4 when in contact with the non-woven fabric layer 4. Figure 2 As shown, the size of the second adhesive layer 53 is smaller than that of the first adhesive layer 51 and can pass through the outlet hole 52, so that when the indwelling needle extension tube is fixed, it can be fixed in an "eight" cross shape, further improving the fixing effect of the indwelling needle extension tube. It should be noted that the first adhesive layer 51 and the second adhesive layer 53 are integrally formed with the non-woven fabric layer 4, and can be fixed to the surface of the non-woven fabric layer 4 by gluing or sewing.

[0048] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2 As shown; the second fixing assembly 6 includes:

[0049] A double-sided adhesive layer 61 is adhered to the first adhesive layer 51; and

[0050] The protective layer 62 is adhered to the other side surface of the double-sided adhesive layer 61, wherein the function of the protective layer 62 is similar to that of the easy-tear layer 1, and its purpose is to protect the surface of the double-sided adhesive layer 61 away from the first adhesive layer 51 from contamination, so that it can be firmly adhered to its surface when the indwelling needle extension tube is fixed.

[0051] The specific working principle of the sterile dressing of a peripheral venous indwelling needle of the utility model is as follows:

[0052] First, the easy-to-tear layer 1 can be torn off, and the fixing patch 2 can be attached to the vicinity of the needle tip of the indwelling needle, so that the needle tip of the indwelling needle is exposed under the transparent dressing 7. The transparent dressing 7 allows medical staff to clearly see the puncture point of the indwelling needle on the skin, and whether there is inflammatory reaction such as redness, swelling, exudation, etc. around the puncture point, which helps to timely discover and deal with possible complications. At the same time, with the use of the writing layer 8, it can be used to record and mark the relevant information of the indwelling needle, such as the type of indwelling needle, the indwelling time, the signature of the medical staff, etc., so that the medical staff can quickly understand the situation of the indwelling needle and avoid confusion or mistakes.

[0053] Next, after tearing off the protective layer 62, the indwelling needle extension tube is pasted onto the surface of the double-sided adhesive layer 61, and the indwelling needle extension tube is limited and fixed by the double-sided adhesive layer 61 to prevent it from moving up and down;

[0054] Finally, the second adhesive layer 53 is passed around the outside of the indwelling needle extension tube through the outlet hole 52 and adhered to the non-woven fabric layer 4, and the first adhesive layer 51 is passed around the outside of the indwelling needle extension tube and adhered to the non-woven fabric layer 4, so that the indwelling needle extension tube can be cross-fixed to prevent it from shifting left and right, thereby ensuring that the indwelling needle is in the correct position and remains stable, avoiding unnecessary movement and shaking, and at the same time reducing further pressure on the skin, alleviating the patient's discomfort and reducing the risk of skin damage.
