[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: an emergency ECMO blood circuit fixation strap, including a strap 1 and a fixation strap 2. One end of the strap 1 is fixedly connected to the side of the fixation strap 2. A hook and loop fastener 5 is fixedly connected to the outer side of the end of the strap 1 near the fixation strap 2. A loop and loop fastener 15 is fixedly connected to the inner side of the other end of the strap 1. The top of the hook and loop fastener 5 is adhered to the bottom of the loop and loop fastener 15. Ventilation holes 6 are provided on both sides and the top of the strap 1. A double... The adhesive tape 3 and the fixing band 2 are folded in half with through holes at the fold. After the fixing band 2 is folded in half, it is fixed by bonding the two ends of the double-sided adhesive tape 3. The wrapping length can be flexibly adjusted to adapt to patients of different body types by bonding the hook side 5 and the loop side 15 of the hook and loop. Fixing and disassembly are convenient and quick, avoiding skin pulling and causing discomfort. The ventilation holes 6 on the surface of the band 1 improve breathability and reduce sweating. The connection between the needle and the tubing is fixed by the fixing band 2 and the double-sided adhesive tape 3 without affecting the disassembly and assembly process and with good support.

[0023] The top of the fixing strap 2 is fixedly connected to the hook and loop fastener 4. The top of the hook and loop fastener 4 is bonded to the bottom of the hook and loop fastener 15. The hook and loop fastener 15 is bonded to the hook and loop fastener 5 and also to the hook and loop fastener 4, which improves the stability of the fixing strap 2 and provides good support and fixation for the blood tubing.

[0024] Rubber protrusions 7 are fixedly connected to both sides of the inner side of the strap 1. The rubber protrusions 7 are hemispherical and contact the skin, so that there is a certain distance between the inner side of the strap 1 and the skin to improve breathability.

[0025] The bottom inner side of the strap 1 has a ventilation groove 8, and a rubber strip 9 is fixedly connected to the bottom inner side of the strap 1. The ventilation groove 8 and the rubber strip 9 are arranged alternately, and the rubber strip 9 raises the bottom of the limb so that the ventilation groove 8 can provide good breathability.

[0026] The bottom of the fixing strap 2 is provided with a groove 10, and a hemostatic cotton pad 11 is fixedly connected to the inner wall of the groove 10. After the needle is removed, the hemostatic cotton pad 11 is pressed on the needle hole to stop bleeding.

[0027] A ring-shaped adhesive tape 13 is glued to the bottom groove 10 of the fixing strap 2. A baffle 12 is fixedly connected to the bottom of the ring-shaped adhesive tape 13. When fixing the pipeline, the baffle 12 covers the hemostatic cotton pad 11 to protect it and prevent the hemostatic cotton pad 11 from being contaminated.

[0028] Both the surface of the strap 1 away from the fixing strap 2 and the surface of the hook and loop fastener 15 are provided with a strip groove 14. After the hook and loop fastener 15 is glued and fixed, the excess strap 1 and hook and loop fastener 15 can be torn apart through the strip groove 14 to avoid tangling with other equipment and causing accidents. It is also more convenient without the need for scissors.

[0029] The surface of the Velcro loop 15 has small holes that correspond to the openings of the ventilation holes 6, so as to avoid affecting the breathability of the top of the strap 1.

[0030] Working principle: Place the connection point between the needle and the blood tubing at the top of the fixation band 2. Then, wrap the fixation band 2 around the surface of the tubing connection and fold it in half. Secure the tubing with double-sided tape 3, and use the self-adhesive sides of the double-sided tape 3 to keep the fixation band 2 folded. The tubing passes through the through-hole formed in the middle of the fixation band 2 to complete the connection. Then, wrap the bandage 1 around the patient's limb that needs fixation, so that the bottom of the fixation band 2 fits against the upper part of the limb. At this time, the ventilation groove 8 and the rubber strip 9 are located under the limb and are pressed down. Then, the end of the bandage 1 away from the fixation band 2 and... The hook and loop fastener 15 presses against the fixing strap 2 and the hook and loop fastener hook side 5, ensuring the strap 1 stays securely on the limb. The hook and loop fastener 15 adheres to the hook and loop fastener hook side 4, enhancing the support of the fixing strap 2 for the tubing and making it less prone to slipping or falling off. The slotted groove 14, located on one side of the strap 1 and the hook and loop fastener 15, has an opening that runs through the strap. Excess parts of the strap 1 and the hook and loop fastener 15 can be directly torn off at the opening of the slotted groove 14 as needed, preventing excess parts from getting tangled in other equipment and causing accidents, and eliminating the need for scissors, making it more convenient. During use, the rubber strip 9 provides support and anti-slip properties, fitting snugly against the bottom of the limb to elevate it, allowing the ventilation groove 8 to improve breathability. The rubber protrusions 7 on both sides fit snugly against the sides of the limb, also providing support and anti-slip properties. A gap is left between the limb and the inner side of the strap 1 to improve breathability, increasing the ventilation area and reducing discomfort. After use, first peel the hook and loop side 15 off the hook and loop side 2 5 and hook and loop side 4. Then slowly open the fixing strap 2 to separate the double-sided tape 3 from the surface of the tubing. Remove the bandage 1 from the limb, then pull out the needle and quickly tear the baffle 12 from the bottom of the fixing strap 2. Then press the hemostatic cotton pad 11 onto the needle hole of the limb to stop the bleeding. Next, wrap the bandage 1 around the limb and stick the hook and loop side 15 and hook and loop side 2 5 together so that the hemostatic cotton pad 11 can be continuously pressed on the bleeding site. It is more convenient without the need for additional hemostatic cotton. When removing the bandage 1 from the limb, it will not tear the skin. The fixing and disassembly process is quick and convenient. It solves the problem that traditional ECMO blood circuit fixing mostly uses medical tape wrapping, which has poor ventilation during use, causes skin sweating and discomfort, and is troublesome and causes skin pulling and discomfort during disassembly.
