Description

A special communication irrigator for interventional operation catheter

technical field

The utility model relates to a medical instrument, in particular to a special communication flusher for an interventional operation catheter.

Background technique

In clinical interventional operations, a syringe is often used to push the contrast agent by hand for roadmap, "smoke" or angiography. During this process, the syringe is likely to form a thrombus due to blood contamination. Once the thrombus is injected into the cerebrovascular, it will cause serious consequences of stroke. . In order to avoid this phenomenon during the operation, once it is contaminated with blood, the surgeon should flush the syringe in time. At present, the common problem is that there is a lack of special equipment for syringe flushing in clinical practice. The surgeons all use blood-stained syringes in a container (usually a basin or bowl) to aspirate heparin saline for flushing, and the flushed saline is directly injected into the container and discarded. In the bucket of liquid, this operation is usually repeated many times, even dozens of times during the operation. The work of flushing the syringe multiple times increases the complexity of the surgical operation, and in the process, it is easy to cause the dampness of the sterile table and the contamination of the floor of the catheter room. It may fall into the container containing heparin saline, and the thrombus will be sucked into the syringe during the next flushing, which increases the hidden danger of intraoperative thromboembolism.
