Problems solved by technology
The existing compression hemostasis device has the following problems: there is a long time interval between the puncture needle being pulled out and the final pressing structure pressing the puncture point. During this time interval, the puncture point may still bleed, and the time interval is relatively long. The reason for the length is that it is necessary to move the patient's forearm and bind the strap on the patient's wrist. At the same time, not only is there a longer time interval, but there is also the need to move the patient's forearm. The process of moving the patient's forearm may also be Causes increased bleeding in patients, and for some seriously ill patients, it is easy to cause secondary injury to the patient

The invention relates to a compression hemostasis device for radial artery puncture. The compression hemostasis device comprises a pressing structure, a wrist support and an arm support, wherein each of the wrist support and the arm support comprises a support body and a slide rail, and an arm support bandage is arranged on the arm support. The compression hemostasis device further comprises a left sliding support and a right sliding support which are used for moving between the arm support and the wrist support along the slide rails, wherein an arc-shaped counter-force arm with a downward notch stretches across the left sliding support and the right sliding support, a counter-force arm driving structure for driving the arc-shaped counter-force arm to rotate around the axis of the counter-force arm is arranged on the left sliding support or the right sliding support, the pressing structure is arranged on the lower side of the arc-shaped counter-force arm, the arm support and the wrist support are connected through a locking structure, and after the left side sliding support and the right side sliding support slide to the wrist support from the arm support, the locking structure is driven to be unlocked, and the arm support can be separated from the wrist support. According to the compression hemostasis device for radial artery puncture, a puncture point of a patient can be pressed without moving the forearm of the patient.
Description
technical field [0001] The invention relates to a supporting device in radial artery puncture operation, in particular to a compression hemostasis device for radial artery puncture. Background technique [0002] Radial artery puncture is a common medical treatment method, which can be used for laboratory examination of arterial blood samples, and can also be used for angiographic examination, arterial blood pressure monitoring, or treatment of coronary heart disease. [0003] Different from conventional intravenous injection, radial artery puncture, which punctures the radial artery, has high arterial blood pressure. After the puncture needle is pulled out from the puncture point, effective compression must be performed to stop bleeding to prevent excessive blood loss. The compression hemostatic devices in the prior art are all strap-type structures, and the compression hemostatic device includes a strap, and a pressing structure is arranged on the strap. [0004] When in u...
