Description

Technical Field

[0001] This utility model relates to the field of contrast agent production technology, and in particular to a cardiovascular contrast agent mixing device. Background Technology

[0002] Ultrasound contrast agents, also known as contrast agents, are chemical products injected into human tissues or organs to enhance the imaging effect. During preparation, high-concentration contrast agents (such as iohexol and gadolinium) need to be mixed with physiological saline in a preset ratio to ensure consistent concentration and avoid local high concentration irritation to blood vessels.

[0003] Chinese Patent Publication No. CN 223010344 U discloses a raw material mixing device for the production of ultrasonic contrast agents, applied in the field of ultrasonic contrast agent production technology. It includes a support frame, with a mixing tank bolted inside the support frame. A connecting rod, bolted to the support frame, is welded to the top of the mixing tank. A first motor is bolted to the top of the support frame. By activating the first motor, a hexagonal rotating rod is driven to rotate, allowing the mixing rod to rotate on its own axis while rotating around the center of the hexagonal rod. This multi-directional rotation and agitation of the ultrasonic contrast agent raw materials improves the mixing effect. Activating a second motor drives a threaded rod to engage with a threaded sleeve, thereby adjusting and supporting the hexagonal rotating rod, allowing the mixing rod to move to different heights to agitate the ultrasonic contrast agent raw materials. This reduces uneven mixing of the ultrasonic contrast agent raw materials and improves practicality.

[0004] The existing technical solutions have the following shortcomings: the addition of contrast agent raw materials is a one-time operation during use. If the actual amount used is less than the total amount mixed, the remaining contrast agent may need to be discarded, which has certain room for optimization. Therefore, it is necessary to design a cardiovascular contrast agent mixing device to solve the above-mentioned problems. Utility Model Content
