Syringe for establishing animal intracranial hemorrhage model

Abstract

The invention discloses a syringe for establishing an animal intracranial hemorrhage model, and belongs to the field of experimental equipment. A piston pushing core and a pushing core fixing block are connected through screw thread fit, the piston pushing core penetrates through the pushing core fixing block to be connected with the upper end of a piston; the piston is located in a syringe outercylinder, and in close contact with the inner wall of the syringe outer cylinder; the syringe outer cylinder comprises an upper threaded section, a middle pipe body section and a lower threaded section, the pushing core fixing block is connected with the upper threaded section through the screw thread fit, a syringe needle height adjusting bottom cylinder is connected with the lower threaded section through the screw thread fit; a lower protruding part of the syringe needle height adjusting bottom cylinder is connected with an injection needle. The syringe disclosed by the invention is reasonable in structural design, and achieves the purposes of slowly injecting blood into brains at different rates according to experimental requirements in an experiment of establishing the animal intracranial hemorrhage model, and further accurately positioning the positions of hemorrhagic spots.

Description

technical field [0001] The invention belongs to the field of animal experiment equipment, and in particular relates to a syringe for establishing an animal intracranial hemorrhage model. Background technique [0002] There are many kinds of human diseases, and the development process is usually very complicated, so it is necessary to carry out medical experiments to explore the pathogenesis of various diseases and evaluate the efficacy, so as to control diseases, prolong human life, and promote the progress of medical research. However, directly applying various medical experiments to the human body may bring risks to people, and because some diseases are not common or have a long incubation period, the development of medical research is greatly limited. Animal experiments are an important part of the field of medical research. A large number of medical studies have shown that animal model experiments that simulate human diseases can effectively overcome many shortcomings of...

AI Technical Summary

Problems solved by technology

However, it is difficult to ensure the slow injection of blood into the brain by using a micro-syringe or an ordinary liquid syringe, and it is impossible to simulate the real human cerebral hemorrhage process. It is difficult to ensure the consistency and repeatability of animal model establishment
