An arteriographic puncture device for cardiovascular department

Abstract

The invention discloses an angiographic puncture device for cardiovascular department, which belongs to the technical field of medical instruments. The device includes an arc-shaped fixing buckle, an accurate positioning element, a puncture element, a control element, and a power supply; the present invention sets an accurate positioning element between the puncture element and the arc-shaped fixing buckle, that is, drives the arc-shaped positioning through a micro-drive motor. When the plate moves, when the infrared sensor detects the artery at the puncture position, the micro magnets corresponding to the micro electromagnetic coil attract each other, and the arc positioning plate is positioned, that is, the puncture position is accurately positioned, which has the advantages of accurate positioning and high reliability. When the puncture position is reached, the vertical clamping groove on the inner wall of the puncture positioning sleeve and the vertical clamping bar on the outer wall of the limit mounting seat are used to insert and connect, so as to increase the stability of the puncture needle and prevent the needle from running off and causing harm to the patient. harm.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an arteriographic puncture device for cardiovascular department. Background technique [0002] Puncture, a commonly used surgical term in medicine, is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is to draw blood for testing , Blood transfusion, infusion and catheterization for angiography. [0003] Arteriography is one of the X-ray examination methods, which is an examination method for visualizing the arterial system by directly injecting contrast medium into the artery to fill the artery with contrast medium. The distribution, number, and shape of the human arterial system are relatively constant. Angiographic examination is mainly arteriogra...

Problems solved by technology

According to the position of the catheter tip from the vessel of interest, it can be divided into non-selective angiography, selective angiography and superselective angiography. Since the advent of DSA (digital subtraction angiography), most arteriography can be performed by DSA, B Ultrasound, CT, and MRI are increasingly used to visualize the arterial system, but these tests are not intended to replace arteriography in the foreseeable future

[0004] Arteriography requires intra-arterial catheterization, which is an invasive examination and requires the use of an arterial puncture device. However, when the existing arterial puncture device is used for puncture, the puncture needle is prone to deviation, causing secondary damage to the patient and increasing the patient's safety. Pain; when the medical staff pulls out the needle, the blood is easily sprayed on the hands of the medical staff or the external environment, and when the medical staff inserts the interventional guide wire, the blood on the hand is brought back to the disturbed artery to cause bacterial infection, Reduce the cure rate, therefore, there is an urgent need for a puncture device that is accurate and stable in puncture, and blood is not easy to eject to meet the requirements of use
