Description

Technical Field

[0001] This utility model relates to the field of arterial catheterization technology, and specifically to an arterial catheterization fixation device. Background Technology

[0002] Arterial catheterization is a clinical technique that involves inserting a catheter into an artery for invasive blood pressure monitoring, blood gas analysis, or drug infusion. Most existing methods of securing arterial catheters use adhesive tape. When it is necessary to remove the arterial catheter, tearing off the tape may cause the tape and the arterial catheter to shift, which may cause stinging pain to the needle inside the body. Furthermore, the tape makes it inconvenient to replace blood collection catheters after they are in place. Therefore, an arterial catheter fixation device is proposed. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides an arterial catheter fixation device.

[0004] The technical solution adopted by this utility model to solve its technical problem is an arterial catheter fixation device, including a first adhesive fabric and a second adhesive fabric. The first adhesive fabric is movably connected to the top surface of the second adhesive fabric through a connecting layer. A first medical pressure-sensitive adhesive is pasted on the bottom surface of the first adhesive fabric. The first adhesive fabric is attached to the top surface of the second adhesive fabric through the first medical pressure-sensitive adhesive. A transparent film is provided at the center of the first adhesive fabric. A fixing cavity is opened at the center of the second adhesive fabric. The fixing cavity is adapted to the transparent film. A second medical pressure-sensitive adhesive is pasted on the bottom surface of the second adhesive fabric.

[0005] By adopting the above technical solution, when disassembling the arterial catheter, since the first adhesive material is pasted on the surface of the second adhesive material, it is only necessary to tear off the first adhesive material to complete the disassembly of the arterial catheter, and the arterial catheter will not be displaced.

[0006] Specifically, a first strap is fixedly connected to one side of the second bonding fabric, and one side of the first strap has a Velcro closure.

[0007] By adopting the above technical solution, the first strap serves as the basic part of the main fixing structure, and its Velcro surface provides an adhesive surface for subsequent adjustment and fixing.

[0008] Specifically, a second strap is fixedly connected to the side of the second bonding fabric away from the first strap, and one side of the second strap is provided with a hook and loop fastener, which is adapted to the hook and loop fastener loop.

[0009] By adopting the above technical solution, the second strap can wrap around the limb and form a closed loop with the first strap for fixation. The circumference can be adjusted by the staggered bonding of the hook side and the loop side of the Velcro, adapting to the different limb thicknesses of different patients.

[0010] Specifically, a fixing layer is fixedly connected to one side of the second bonding fabric, a button is sewn onto the top surface of the fixing layer, and a positioning layer is fixedly sewn onto the top surface of the second bonding fabric.

[0011] Specifically, a limiting strap is fixedly connected to one side of the first bonding fabric, the limiting layer is used for the limiting strap to pass through, and the button is adapted to the limiting strap.

[0012] By adopting the above technical solution, the first bonding fabric is mechanically reinforced by the limiting band and the button. Combined with the notch design of the medical pressure-sensitive adhesive, it can not only realize the quick disassembly and replacement of the catheter, but also avoid the pulling damage caused by the direct sticking of the tape to the catheter.

[0013] The beneficial effects of this utility model are:

[0014] The arterial catheter fixation device described in this utility model allows for easy disassembly of the arterial catheter by simply peeling off the first adhesive fabric, which is adhered to the surface of the second adhesive fabric. This prevents displacement of the arterial catheter. The first adhesive fabric is mechanically reinforced by the limiting band and buttons, and the notch design of the medical pressure-sensitive adhesive allows for quick catheter removal and replacement while avoiding pulling damage caused by direct adhesion of adhesive tape to the catheter.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As one embodiment of this utility model, such as Figures 1-3 As shown, the arterial catheter fixation device of this utility model includes a first adhesive fabric 8 and a second adhesive fabric 11. The first adhesive fabric 8 is movably connected to the top surface of the second adhesive fabric 11 through a connecting layer 9. A first medical pressure-sensitive adhesive 13 is adhered to the bottom surface of the first adhesive fabric 8. The first adhesive fabric 8 is adhered to the top surface of the second adhesive fabric 11 through the first medical pressure-sensitive adhesive 13. A transparent film 10 is provided at the center of the first adhesive fabric 8. A fixing cavity 12 is provided at the center of the second adhesive fabric 11. The fixing cavity 12 is adapted to the transparent film 10. A second medical pressure-sensitive adhesive 14 is adhered to the bottom surface of the second adhesive fabric 11.

[0022] In use, the second medical pressure-sensitive adhesive 14 is used to precisely position the second adhesive fabric 11 at the arterial puncture site. The cooperation between the transparent film 10 and the fixed cavity 12 ensures the space for puncture operation and allows for visual observation of the catheter placement status later.

[0023] It should be noted that the first bonding fabric 8 needs to be tightly attached to the outer surface of the second bonding fabric 11 to ensure the vertical downward pressure of the transparent film 10. The first medical pressure-sensitive adhesive 13 has a notch for the catheter to pass through without sticking to the catheter. The connecting layer 9 is made of cotton fabric. The two ends of the connecting layer 9 are fixedly connected to one side of the first bonding fabric 8 and one side of the second bonding fabric 11 respectively by needle and thread sewing, which allows the second bonding fabric 11 and the first bonding fabric 8 to be flexibly connected.

[0024] The present invention also includes a first strap 2 fixedly connected to one side of the second bonding fabric 11, and a Velcro surface 1 is provided on one side of the first strap 2.

[0025] In use, the first strap 2 serves as the base of the main fixing structure, and its Velcro surface 1 provides an adhesive surface for subsequent adjustment and fixing.

[0026] The present invention further includes a second strap 7 fixedly connected to the side of the second bonding fabric 11 away from the first strap 2, and a hook and loop fastener 15 provided on one side of the second strap 7, wherein the hook and loop fastener 15 is adapted to the hook and loop fastener 1.

[0027] When in use, the second strap 7 can wrap around the limb and form a closed loop with the first strap 2 for fixation. The circumference can be adjusted by the staggered bonding of the hook side 15 and the loop side 1 of the Velcro, so as to adapt to the different limb thicknesses of different patients.

[0028] The present invention also includes a fixing layer 6 fixedly connected to one side of the second bonding fabric 11, a button 5 sewn onto the top surface of the fixing layer 6, and a positioning layer 4 fixedly sewn onto the top surface of the second bonding fabric 11.

[0029] The present invention also includes a limiting strap 3 fixedly connected to one side of the first bonding fabric 8, the limiting layer 4 for the limiting strap 3 to pass through, and the button 5 adapted to the limiting strap 3.

[0030] When in use, the limiting band 3 passes through the limiting layer 4 and then fastens with the button 5 to strengthen and fix the first bonding fabric 8.

[0031] In use, the second adhesive fabric 11 is first aligned with the artery to be punctured by the fixing cavity 12 and then attached by the second medical pressure-sensitive adhesive 14. The first strap 2 and the second strap 7 are then wrapped around the patient's artery puncture site. The hook side 15 of the Velcro is adjusted to adhere to the loop side 1 of the Velcro according to the thickness of the site, thereby strengthening the fixing effect of the second adhesive fabric 11. The doctor then performs arterial catheterization at the fixing cavity 12. After the puncture, the arterial catheter is left in the fixing cavity 12, and the blood collection catheter extends through the limiting layer 4. The first adhesive fabric 8 and the first medical pressure-sensitive adhesive 13 are then tightly attached to the outer surface of the second adhesive fabric 11, allowing the transparent film 10 to press against the surface of the arterial catheter, thus fixing it. The limiting band 3 is then passed through the limiting layer 4 and covered the catheter surface. The fixing layer 6 is connected to the limiting band 3 by the button 5 and the button hole, further strengthening the fixing of the first adhesive fabric 8.
