Abstract

The invention relates to a laboratory animal body fluid collection needle assembly. The assembly comprises a puncture needle, a pipe cover, a body fluid collection pipe and a shaking device, wherein the puncture needle is in sealed connection with the pipe cover; a puncture needle connector is fixedly connected onto the pipe cover, a handle is fixedly connected with the side surface, and an internal thread is arranged on the inner wall; an external thread is arranged at an upper end port of the body fluid collection pipe, and an air hole is fixedly connected with the side surface; and the shaking device consists of a base, a support, a carrying board and a knob. The assembly has the advantages as follows: the puncture needle has shapes for different body fluid collection requirements and can conveniently and rapidly collect corresponding body fluids by flexible application; various anticoagulants, coagulants, hydrochloric acid and other agents which can prevent body fluids from deteriorating can be added to the body fluid collection pipe in advance; the air hole at the wall of the body fluid collection pipe ensures balance of air pressure inside and outside the pipe, and an isolation layer can prevent poor circulation of body fluids; and the shaking device can conveniently mix the body fluids with agents added in advance, prevent the body fluids from deteriorating and avoid non-uniform manual mixing.

Description

technical field [0001] The invention relates to the technical field of animal experiment equipment, in particular to an experimental animal body fluid collection needle assembly. Background technique [0002] Body fluids are fluids in the body, including saliva, semen, leucorrhea, human milk, blood, lymph, urine, cerebrospinal, pleural effusion, peritoneal fluid or effusion, joint cavity fluid, amniotic fluid, etc. These body fluids contain diagnostic markers related to diseases, such as the pH of urine, whether there are excessive red blood cells, white blood cells and small round epithelial cells, etc. are important indicators in clinical diagnosis and treatment, and are also important indicators for experimental animals in teaching and scientific research. Important samples collected for relevant disease models. [0003] Blood tests can determine the health status of experimental animals, the specificity of disease model animal construction, etc.; urine tests can determi...
