Description

Technical Field

[0001] The present invention relates to the field of cardiology-related technical fields, and more particularly to the field of contrast agent processing technology for cardiology angiography, and in particular to a contrast agent processing machine. Background Art

[0002] Cardiac angiography is an important diagnostic technique in the field of cardiology. It is a highly professional and accurate detection method used to evaluate the structure and function of heart vessels (especially coronary arteries). It injects contrast agents into the blood vessels and uses X-ray imaging technology to observe the blood flow in the blood vessels and potential lesions in real time. When performing angiography on different parts, different contrast agents need to be injected to reduce damage to the human body. Contrast agents are usually made by mixing different solutions, so they need to be processed before injection; For example, the invention with application number CN202211681733.7 discloses a contrast agent heating device in the field of contrast agent processing technology, including a main box and a cover plate, wherein a stirring box and an annular heating tank are provided in the main box, a stirring assembly and a liquid outlet assembly are provided in the stirring box, a rotating assembly and a plurality of placement assemblies are provided in the annular heating tank, a driving shaft is connected between the rotating assembly and the top of the stirring assembly through a transmission assembly, and the present invention heats the contrast agent in a water bath by placing a bottle of contrast agent in a plurality of placement assemblies, and driving the rotating assembly to drive the placement assembly and the contrast agent bottle to move in the annular heating tank through a driving assembly, while avoiding stratification or precipitation of the contrast agent when it is stationary, which affects the subsequent use of the contrast agent; the driving shaft stirring assembly is connected by adjusting the transmission assembly, so that the liquid medicine in the stirring box is heated and stirred and mixed by the stirring assembly, thereby switching or using different heating methods at the same time according to the use needs, thereby improving the use range and flexibility of the heating device; For another example, the invention with application number CN202210005105.0 discloses a contrast agent processing device for cardiology angiography surgery, including a base plate, characterized in that: one end of the upper side of the base plate is fixedly connected to the lower end of a trapezoidal slide rail, and the trapezoidal slide rails are respectively arranged in corresponding trapezoidal slide grooves, and the upper sides of the two trapezoidal slide grooves are respectively fixedly connected to the lower side of the box body, and the middle part of one side of the box body is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to an eccentric part of one side of a disc, and the center of the disc is fixedly connected to the output shaft of motor one, and motor one is fixedly connected to one end of the upper side of the base plate. This device can conveniently heat and mix the contrast agent.

[0003] In combination with the actual clinical use of cardiology, it is found that the current contrast agent processors still have certain disadvantages when used, such as: 1. The prepared contrast agent raw materials cannot be directly introduced into the mixing and processing chamber, and need to be manually poured, which not only increases the operation steps, but also increases the risk of contamination of the contrast agent raw materials. At the same time, direct pouring and mixing of different types of contrast agent raw materials will affect the mixing quality of the contrast agent and the clarity of the contrast. 2. By rotating the contrast agent raw material, it can be prevented from settling. However, in actual use, the centrifugal effect of the rotation will affect the mixing and use of the contrast agent raw material; 3. The overall structure is dispersed, occupying the space in the catheterization room, and the distributed arrangement is not convenient for rapid operation and use, which is not conducive to improving the efficiency of cardiac angiography.
