Technical field
The utility model relates to technical field of medical instrument, specifically, being a kind of dedicated fixed station of mouse bone marrow cells puncture.
Background technique
Bone marrow puncture (Bone Marrow Puncture) is a kind of common diagnostic techniques of clinically bone marrow extraction liquid.
Be the proliferative conditions of long term monitoring mouse bone marrow cells when constructing mouse leukemia model, it would be desirable to acquire the bone marrow fluid of mouse into
Row analysis.However, not only having lacked mature mouse living body bone in zoopery wears technology, but also lack the bone marrow aspiration for being suitable for mouse
Fixed device.
In order to overcome this difficulty, the method that we have used for reference rat marrow puncture is improved: 1, by mouse peritoneal fiber crops
Liquor-saturated, preserved skin at knee joint, mouse takes lateral position, and experimenter's index finger and thumb fix the shin bone of mouse;2, with common 1ml mono-
Secondary property is pierced into tibial shaft from tibial plateau from the knee joint of mouse using asepsis injector, penetrates after fixing and extracts;3, it uses
The sterile insulin syringe of 1ml of anti-coagulants lubrication is pierced into shin bone pulp cavity, bone marrow extraction liquid along 1ml syringe puncture orifice.But
Be that this experimental method still remains many defects: 1, experimenter fixes mouse tibia manually, and finger is easy to be missed by syringe needle
Wound, it is abnormally dangerous;2, it is not easy to neophyty operation.
So being badly in need of a kind of dedicated fixed station of mouse bone marrow cells puncture that can solve the above problem at present.
