Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a femoral artery catheter fixing device. Background Art

[0002] Hepatic artery infusion chemotherapy (HAIC) has been used in patients with advanced liver malignancies and has been shown to have good response rates and survival benefits. HAIC treatment has been written into the National Health Commission's "Guidelines for the Diagnosis and Treatment of Primary Liver Cancer (2022 Edition)". For some patients with liver malignancies, HAIC treatment can be used when transarterial chemoembolization is ineffective. HAIC is a catheter inserted through a puncture in the femoral artery, with the tip of the catheter connected to the liver tumor blood supply artery, and chemotherapy drugs are infused at a uniform rate. During the treatment, the patient needs to carry the femoral artery catheter for more than 48 hours.

[0003] The following problems occurred during the clinical implementation process: 1. The exposed femoral artery tube (including vascular sheath, catheter and microcatheter) is about 60 cm long and needs to be fixed at the root of the thigh. Currently, there is no device to fix the exposed catheter in clinical practice. In order to avoid folding, twisting, or even dislodging of the tube, medical staff need to spend a lot of time wrapping the exposed catheter with multiple layers of gauze and then fix it with an elastic bandage.

[0004] 2. A common complication of femoral artery puncture is bleeding at the puncture site. Currently, catheter fixation requires wrapping and covering with multiple layers of gauze, which is not conducive to the observation of bleeding and poses a safety hazard.

[0005] 3. The catheter is made of hard material and is fixed on the skin for a long time, which can easily cause pressure damage to the skin and cause harm to the patient.

[0006] 4. The patient stays in bed for a long time, and the existing bandaging and fixation methods reduce the patient's comfort. Utility Model Content

[0007] The utility model aims to provide a femoral artery catheter fixing device with better use effect.

[0008] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0009] A femoral artery catheter fixing device comprises a puncture port sterile area and a catheter fixing base, wherein the puncture port sterile area is connected and installed above the catheter fixing base, and both the puncture port sterile area and the catheter fixing base are latex pad structures; a U-shaped notch is provided above the puncture port sterile area, and a femoral artery puncture port is reserved at the U-shaped notch; the U-shaped notch is used to fix a vascular sheath in direct contact with a patient's blood vessel and an exposed catheter connected to the vascular sheath; a fixing assembly is provided on the catheter fixing base, and the fixing assembly is used to fix the exposed catheter connected to the vascular sheath; a sterile film is provided on one side of the puncture port sterile area, and the sterile film is used to seal the contact between the vascular sheath and the outside world.

[0010] It can be seen that after the femoral artery puncture tube of the patient is completed, the sterile area of the puncture site and the back of the catheter fixing base are closely attached to the root of the patient's thigh. The latex pad structure can reduce the pressure on the skin and avoid causing pressure injury to the patient's skin. The exposed catheter and vascular sheath are initially fixed through the use of the U-shaped notch, and then one end of the exposed catheter is fixed using the fixing component. By using the fixing component, it is possible to prevent the exposed catheter from being folded, twisted, or even dislodged, reducing the working time of medical staff. Instead of using multiple layers of gauze and elastic bandages for wrapping and fixing, it is more convenient to use. After fixing the exposed catheter, the protective film on the sterile dressing is torn off and the sterile dressing is fixed and covered on the sterile area of the puncture site until the femoral artery puncture site and the vascular sheath are completely covered and adhered and fixed. By using the sterile dressing, the contact between the vascular sheath and the outside can be reduced, thereby maintaining the sterile state at the sterile area of the puncture site. Finally, the remaining exposed catheter is straightened and fixed one by one using the remaining fixing components to avoid the remaining exposed catheter from being folded, twisted, or even dislodged, making the fixing effect better.

[0011] Furthermore, the fixing component includes a rough surface fixing band and a sticky surface fixing band; the catheter fixing base is in a butterfly shape, and the fixing component is a Velcro structure, with a total of four distributed in a rhombus shape on the catheter fixing base; the exposed catheter is installed on the upper surface of the catheter fixing base through the cooperation of the rough surface fixing band and the sticky surface fixing band.

[0012] The butterfly-shaped catheter fixing base can increase the adhesion area between the device and the patient's skin, thereby making the fixing effect of the device better. The fixing components distributed in a rhombus shape can fix the exposed catheter to a greater extent, improving the fixing effect. The device with a Velcro structure can not only achieve the fixing effect but also make the operation more convenient, and medical staff can also use it more quickly, reducing the time of medical staff.

[0013] Furthermore, the center point of the sterile dressing corresponds to the femoral artery puncture site of the patient and completely covers the sterile area of the puncture site.

[0014] The center point of the sterile dressing corresponding to the femoral artery puncture site of the patient can completely cover the sterile area of the puncture site, thereby closing the contact between the exposed catheter and the outside. During a long-term thrombolysis operation, it can continuously maintain the sterile state of the sterile area of the puncture site, prevent external bacterial infection, and avoid infections and other situations at the femoral artery puncture site and the exposed catheter.

[0015] Furthermore, the sterile dressing is a transparent dressing.

[0016] The transparent sterile dressing can facilitate medical staff to observe whether there are abnormal conditions such as bleeding at the puncture site, facilitating timely follow-up treatment.

[0017] Further, a first self - adhesive latex pad and a second self - adhesive latex pad are respectively arranged on the lower surface of the sterile area of the puncture site and the catheter fixing base.

[0018] The self - adhesive latex pad can closely adhere to the patient's thigh root according to the body undulation of the patient, making the fixing effect better, and the material is soft, so that serious pressure injuries on the skin will not occur during long - term fixation.

[0019] Further, the sterile area of the puncture site, the catheter fixing base, and the sterile dressing are of an integrated structure.

[0020] The integrated structure design is convenient to use and can save operation time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following describes the present utility model in detail with reference to the accompanying drawings.

[0026] As Figures 1-3 shown, a femoral artery catheter fixing device includes a sterile area 1 of the puncture site and a catheter fixing base 2. The sterile area 1 of the puncture site is connected and installed above the catheter fixing base 2. Both the sterile area 1 of the puncture site and the catheter fixing base 2 are of latex pad structures. A U - shaped notch 101 is opened at the upper position of the sterile area 1 of the puncture site, and a femoral artery puncture site 11 is left at the U - shaped notch 101. The U - shaped notch 101 is used to fix the vascular sheath 4 in direct contact with the patient's blood vessel and the exposed catheter 3 connected to the vascular sheath 4. A fixing component 5 is arranged on the catheter fixing base 2, and the fixing component 5 is used to fix the exposed catheter 3 connected to the vascular sheath 4. A sterile dressing 6 is arranged on one side of the sterile area 1 of the puncture site, and the sterile dressing 6 is used to seal the contact between the vascular sheath 4 and the outside.

[0027] During the specific use process, after the femoral artery puncture tube of the patient is completed, the sterile area 1 of the puncture site and the back of the catheter fixing base 2 are pre-attached closely to the patient's thigh root. Then, one end of the exposed catheter 3 and the vascular sheath 4 are snapped into the U-shaped notch 101 for preliminary fixation. Next, one end of the exposed catheter 3 is guided to the first fixing component 5 on the upper surface of the catheter fixing base 2 for fixation. After fixing the exposed catheter 3, the protective film on the sterile dressing 6 is torn off, and the sterile dressing 6 is fixed and covered on the sterile area 1 of the puncture site until the femoral artery puncture site 11 and the vascular sheath 4 are completely covered and adhesively fixed. Finally, the remaining exposed catheter 3 is straightened out and then fixed one by one with the remaining fixing components 5, which can prevent the remaining exposed catheter 3 from being folded, twisted, or even dislodged.

[0028] Specifically, the fixing component 5 includes a velcro fixing band 51 and an adhesive fixing band 52; the catheter fixing base 2 is in a butterfly shape, and the fixing component 5 is a magic tape structure, with a total of four distributed in a rhombus shape on the catheter fixing base 2; the exposed catheter 3 is installed on the upper surface of the catheter fixing base 2 by the cooperation of the velcro fixing band 51 and the adhesive fixing band 52. When using the first fixing component 5 on the upper surface of the catheter fixing base 2 to fix the exposed catheter 3, the exposed catheter 3 is placed above the velcro fixing band 51, and then the adhesive fixing band 52 is used to fix the exposed catheter 3. After fixing, the remaining exposed catheter 3 is straightened out, and the remaining four fixing components 5 are used for fixing one by one, so that the fixing effect of the device is better. The fixing components 5 distributed in a rhombus shape can fix the exposed catheter 3 to a greater extent and improve the fixing effect.

[0029] Specifically, the center point of the sterile dressing 6 corresponds to the femoral artery puncture site 11 of the patient and completely covers the sterile area 1 of the puncture site. The center point of the sterile dressing 6 corresponding to the femoral artery puncture site 11 of the patient can completely cover the sterile area 1 of the puncture site, thereby sealing the contact between the exposed catheter 3 and the outside world, and can continuously maintain the sterile state of the sterile area 1 of the puncture site during a long-term thrombolysis operation, prevent external bacterial infection, and avoid infections and other situations at the femoral artery puncture site 11 and the exposed catheter 3.

[0030] Specifically, the sterile dressing 6 is a transparent dressing. The transparent sterile dressing 6 can facilitate medical staff to observe whether there are abnormal conditions such as bleeding at the puncture site, and facilitate timely follow-up treatment.

[0031] Specifically, a first self-adhesive latex pad 12 and a second self-adhesive latex pad 21 are respectively arranged on the lower surfaces of the sterile area 1 of the puncture site and the catheter fixing base 2. The self-adhesive latex pad can closely adhere to the patient's thigh root according to the body undulation of the patient, making the fixing effect better, and the material is soft, and it will not cause relatively serious pressure injuries to the skin during long-term fixation.

[0032] Specifically, the sterile area 1 of the puncture site, the catheter fixing base 2, and the sterile dressing 6 are of an integrated structure. The integrated structure design is convenient to use and can save surgical time.
