Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a brachial artery hemostatic wristband. Background Art

[0002] The brachial artery is located between the triceps and biceps on the inner side of the arm between the armpit and the elbow. Common brachial artery hemostasis methods include finger pressure hemostasis, tourniquet hemostasis, etc. The bleeding site of the artery is accurately located, the bleeding site is pressed by hand, and the blood vessel is pressed hard to stop the blood flow or a tourniquet is used. The affected limb is raised for 12 minutes before the tourniquet is applied. Above the bleeding site, such as the upper arm or the upper 1 / 3 of the thigh, the skin is first bandaged with a towel or cotton pad, and then the tourniquet is stretched and tightened and wrapped around the outside of the towel or other objects. The above-mentioned finger pressure hemostasis method has problems such as easy deviation of the pressing position, inability to be flexible, and inability to quickly adjust the pressure on the wound. The existing hemostasis device solves the problems of the above-mentioned finger pressure hemostasis method by using methods such as inflatable airbags or thread-adjustable compression plates to achieve hemostasis. However, it still has the following shortcomings:

[0003] 1. Finger pressure hemostasis method requires pressing the blood vessels above the bleeding site with fingers. Press for 20-30 minutes and relax for 3-5 minutes to prevent limb ischemia and necrosis from causing damage to the limb. The operation process of repeatedly adjusting the inflation volume of the inflatable airbag or adjusting the clamping force of the clamping plate is cumbersome, which reduces work efficiency and is prone to displacement during adjustment.

[0004] 2. For women, or elderly people or teenagers with slender arms, when adjusting, especially for such devices that compress the wound through a compression plate, it is easy for the fixing belt between the hemostatic device and the upper arm to shift or loosen, which is not conducive to the compression of the wound and increases the difficulty of adjustment.

[0005] 3. The pressure on the wound cannot be flexibly adjusted, causing the patient's limbs to feel sore and numb, and the patient's comfort level is low.

[0006] Therefore, how to design a brachial artery hemostatic wristband that can solve the above technical problems is a technical problem that needs to be solved. Utility Model Content

[0007] In order to solve the above problems, the purpose of the utility model is to provide a brachial artery hemostatic wristband, which solves the problem that the existing press hemostatic device is prone to displacement during adjustment, making the adjustment operation cumbersome and easy to loosen.

[0009] Furthermore, the upper arm connecting belt 1 and the upper arm connecting belt 2 are respectively fixed on both sides of the connecting plate, the upper arm connecting belt 1 is fixed with a return buckle at one end away from the connecting plate, the inner side surface of the upper arm connecting belt 1 is provided with a Velcro hook surface 1, and the outer side surface of the upper arm connecting belt 2 is provided with a Velcro fur surface 1.

[0010] Furthermore, an airbag is fixedly provided on the inner side surface of the arc-shaped pressing plate.

[0011] Furthermore, the inner side surface of the arc-shaped support plate is covered with a soft cushion.

[0012] Furthermore, the tensioning band 1 and the tensioning band 2 are respectively fixed on both sides of the connecting plate, the end of the tensioning band 1 away from the connecting plate is fixed with a return buckle 2, the inner side surface of the tensioning band 1 is provided with a Velcro hook surface 2, and the outer side surface of the tensioning band 2 is provided with a Velcro fleece surface 2.

[0014] The utility model has the following beneficial effects:

[0015] 1- The utility model is provided with a hemostatic device, which is placed between the brachial artery wound and the body corresponding to the wound, and a force is applied in the direction of the arc-shaped support plate so that the clamping rod is pressed tightly against the wound under the action of the spring to achieve wound hemostasis. The patient can flexibly adjust the pressure on the wound according to the hemostasis situation of the wound and the arm situation, thereby improving flexibility and practicality. At the same time, the air bag on the inner side of the arc-shaped clamping plate is in full contact with the wound, thereby avoiding the situation where the wound cannot be stopped due to pressing on the wrong position, thereby improving the hemostasis efficiency.

[0016] 2-The utility model preliminarily fixes the position of the hemostatic device through upper arm connecting belt 1 and upper arm connecting belt 2, and then wraps the tensioning belt 1 and tensioning belt 2 around the other side of the body to fix the position of the hemostatic device again, and finally fixes it at the shoulder through fixing belt 1 and fixing belt 2. On the one hand, it avoids the movement of the hemostatic device during the compression hemostasis process, and on the other hand, it does not affect the small movement of the forearm.
