Description

Technical Field

[0001] The utility model relates to the technical field of laboratory auxiliary blood collection, in particular to a laboratory mouse auxiliary blood collection device. Background Art

[0002] At present, when drawing blood from the eyes, the operator usually holds the mouse model with one hand to fix the body position (such as pinching the mouse neck skin with the left thumb and index finger, and grasping the mouse abdomen and squeezing with the left middle finger, ring finger and little finger), and then turns the mouse model upside down to make the eyeball congested, and punctures the mouse model's eye with a blood collection needle in the right hand, and then connects the distal end of the blood collection needle to the blood collection tube for blood collection. The above-mentioned eye blood collection method is difficult for one person to operate alone. Holding the mouse model with one hand can easily cause it to shake left and right, making it difficult to accurately puncture the eye for blood collection, and sometimes there is even a risk of puncturing the operator's finger or being bitten and injured by the mouse model; in addition, due to the difficulty of one-handed operation, the mouse model is often inverted for too long and the eyeball is severely congested. At this time, once the puncture is successful, the blood will splash out and cannot be collected into the blood collection needle in time, resulting in the loss and waste of precious blood resources.
