Description

Intubation forceps

Technical Field

The application relates to the field of medical equipment, in particular to intubation forceps.

Background

The arteriovenous intubation model of the rat and the mouse is an animal operation model which is frequently used in the fields of basic medical research, life science and drug research and development, has the functions of blood sampling and multiple administration, can detect indexes such as blood pressure, heart rate and the like, and is particularly suitable for the research of pharmacokinetics and toxicology. The conventional method for intubation of arteriovenous of rat or mouse is to cut a gap on the blood vessel, then use a micro-forceps to extend into the blood vessel near the heart end of the gap, slightly open the forceps, and dilate the blood vessel. The vessel wall was then grasped and lifted with forceps and the vessel cannula was inserted into the vessel by hand. This operation is comparatively loaded down with trivial details, makes the accuracy and the efficiency greatly reduced of intubate.

SUMMERY OF THE UTILITY MODEL
