Description

Auxiliary device for cardiovascular intubation

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to a cardiovascular auxiliary device for intubate is related to.

Background

In cardiovascular surgery, medical staff is often required to intubate the cardiovascular system of a patient, in clinical practice, a manual handheld mode is often used for direct intubation, but some special body parts or tissues are often too difficult to reach or are too unsuitable for human hands, and under the condition, if the handheld intubation is still used, the accuracy is difficult to be effectively guaranteed, intubation failure or inaccurate intubation position is easily caused, and serious medical accidents occur. Therefore, there is a need for improvements to existing intubation methods and aids.

The conventional cardiovascular intubation tube clamping device is generally composed of two elastic clamping arms welded together, and the end parts of the two elastic clamping arms are respectively connected with elastic clamping pieces matched with the periphery of an intubation tube. The cardiovascular clamping device with the structure is too simple in design, too wide and not flexible enough to operate, so that a doctor cannot insert the cannula into the cardiovascular tube quickly and accurately in an operation, and medical accidents are caused.
