[0002] The femoral vein has the characteristics of a large lumen, abundant blood flow, little effect of drugs on the vein wall, and is superficial and easy to fix, with a high puncture success rate. Femoral vein puncture and catheterization is the preferred venous access for some critically ill patients, especially those under emergency stress conditions.

[0003] When treating patients with severe hepatitis, a femoral vein catheter is used to establish a blood access. When the femoral vein is catheterized, since the femoral vein is located on the inner side of the thigh, the indwelling catheter is very likely to come into contact and rub against the human body, thereby causing the catheter to come out. In clinical practice, adhesive tape is usually used to fix the catheter, but this fixation method cannot effectively prevent the catheter from coming out. At the same time, there will be exudate when the femoral vein is catheterized. Medical staff usually use gauze or transparent film dressing to manage the exudate, but this method is prone to infection and requires frequent dressing changes. At the same time, due to poor coagulation function and systemic heparinization after surgery, local bleeding, hematoma, infection and other adverse reactions are prone to occur. Therefore, a catheter fixing dressing for the femoral vein that can effectively fix the flow catheter and effectively manage the exudate is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] A catheter fixation dressing for a femoral vein, such as Figure 1 and Figure 3 As shown, it includes a first adhesive portion 1 and a dressing portion 2 arranged in the middle of the first adhesive portion 1, a through hole 3 corresponding to the puncture point is opened on the dressing portion 2, the through hole 3 is located in the middle of the dressing portion 2, and a square hole 4 is formed by extending from the through hole 3 to the side of the first adhesive portion 1, a connecting portion 5 is arranged on the side of the first adhesive portion 1 close to the square hole 4, a buffer 6 is arranged on the connecting portion 5, a second adhesive portion 61 for fixing it is arranged on the buffer 6, the buffer 6 wraps the indwelling catheter, the surface of the dressing portion 2 is a PU semipermeable membrane, the buffer 6 is in a concave shape, and the end of the indwelling catheter is located in the notch 7 of the buffer 6.

[0025] Among them, the first adhesive part 1 is used to be adhered to the human skin, the dressing part 2 is used to absorb exudate and the lower part of the dressing part 2 is also adhesive and can be adhered to the human skin, the through hole 3 corresponds to the puncture point to facilitate the placement of the retention catheter into the human body, the square hole 4 is used to facilitate the placement of the retention catheter, and the retention catheter can be located on the dressing, the connecting part 5 is used to connect the buffer 6, the buffer 6 is used to cover the tail of the catheter so that the catheter is located at the recess 7 of the buffer 6 to prevent the catheter from directly contacting and rubbing with the human body and causing the catheter to fall out or loosen, and the second adhesive part 61 is used to fix the buffer 6.

[0026] Specifically, after the operator inserts the indwelling catheter into the human body, the operator first fixes the tail of the catheter with tape, and then takes out the catheter fixing dressing to make the through hole 3 correspond to the puncture point, and then adheres the first adhesive part 1 and the dressing part 2 to the skin around the puncture point, and then pushes the first adhesive part 1 and the dressing part 2 at the square hole 4 to the bottom of the catheter, so that the middle of the catheter is located above the catheter fixing dressing, and then covers the tail of the catheter with the buffer 6, and at the same time adheres the second adhesive part 61 of the buffer 6 to the human skin. After fixing the buffer 6, the operator can take out a transparent dressing and adhere it above the first adhesive part 1, the dressing part 2 and the pipeline, thereby closing the through hole 3 and the square hole 4 to prevent the exudate from flowing out of the through hole 3 or the square hole 4. The installation of the catheter fixing dressing is completed through the above operations.

[0027] In summary, by setting the dressing part 2, a large amount of exudate can be absorbed without leakage, and the skin around the puncture point will not be soaked, so as to avoid infection and prolong the dressing change time. By setting the through hole 3, the dressing part 2 can be prevented from adhering to the puncture point, so that the patient does not feel pain when changing the dressing. By setting the surface of the dressing part 2 to be a PU semi-permeable membrane, it is breathable, waterproof, and can block bacteria, which greatly reduces the chance of infection at the puncture point. By setting the dressing part 2 to be a soft material and heat-insulating, the patient's comfort is improved. By setting the buffer 6, the catheter can be covered, so that the catheter will not contact and rub against the human body. When the buffer 6 contacts and rubs against the human body, since the buffer 6 has a buffering function, it can effectively avoid the contact and friction force from being transmitted to the catheter, so that the catheter can be effectively prevented from falling out.

[0028] The buffer member 6 is a hollow structure filled with sponge.

[0029] The outer surface of the buffer member 6 is made of flexible material and the inside is filled with sponge, thereby playing a buffering role.

[0030] like Figure 2As shown, the buffer component 6 is an airbag, and a connecting component 9 and a one-way valve 10 are provided on the airbag. The one-way valve 10 is located inside the airbag. The connecting component 9 is detachably connected with an air intake pipe 8, and the air intake pipe 8 is exposed on the outside of the buffer component 6. Gas can be injected into the airbag through the air intake pipe 8. The air intake pipe 8 is provided with an external thread, and the connecting component 9 is provided with an internal thread. The air intake pipe 8 is threadedly connected to the connecting component 9.

[0031] In order to reduce the space occupied by the buffer member 6 for easy storage, the buffer member 6 is configured as an airbag and the airbag is inflated by steam injection to provide a buffering effect.

[0032] Specifically, the operator can blow air into the interior of the airbag through the air inlet pipe 8, and the airbag will expand. When not injected with air, the airbag is flat and convenient for storage. When in use, it only needs to be injected with air. The one-way valve 10 can ensure that the air can only enter the interior of the airbag and cannot let the gas out of the airbag. After the injection is completed, the operator can remove the air inlet pipe 8 from the connecting piece 9, thereby reducing the space occupied by the airbag when in use.

[0033] like Figure 4 As shown, a first protective film 11 is adhered to the first adhesive portion 1 and the dressing portion 2, and the first protective film 11 is divided into two halves.

[0034] Among them, by setting the first protective film 11, when the catheter fixing dressing is not normally used, the adhesion of the first adhesive part 1 and the dressing part 2 can be maintained by setting the first protective film 11. By dividing the first protective film 11 into two halves, it is convenient for medical staff to tear off the first protective film 11 and then attach the first adhesive part 1 and the dressing part 2 to the human skin.

[0035] The outer sides of the two first protective films 11 are both provided with first tearing portions 12 .

[0036] The first tearing portion 12 further facilitates tearing off the first protective film 11 .

[0037] The outer side of the buffer member 6 is provided with a stabilizing portion 13 that can be bonded, and an integrally formed second protective film 14 is bonded to the second bonding portion 61 and the stabilizing portion 13 , and a second tearing portion 15 is provided on one side of the second protective film 14 .

[0038] The buffer member 6 can be further fixed by providing the stabilizing portion 13 , and the adhesion between the second adhesive portion 61 and the stabilizing portion 13 can be effectively protected by providing the second protective film 14 .

[0039] Specifically, the operator can tear off the second protective film 14 from the stabilizing portion 13 and the second adhesive portion 61 , and then adhere the stabilizing portion 13 and the second adhesive portion 61 to human skin, thereby fixing the buffer 6 .
