Through trial manufacturing of small-model microinjection pump, we implement its technical functions, at the same time we have the new breakthrough from the price.

With stepping motor subdivision control to realize precision injection,and application of multiple sensors to detect the status of the injection,the micro-injection pump is successful implementation of the micro-smart precision liquid injection.

Micro-injection pump could decrease the problems in drug using caused by human factors,reduce phlebitis,vein swelling and pain and other adverse reactions.

Viscous flow field in a mini pump with an asymmetric axis;

Effects of microinjection of GABA and bicuculline into the medial area of the nucleus retrofacialis on respiratory rhythm in nconatal rat: An in vitro study;

The concentration of insulin in hypothalamus,the B_ max and K_ D of insulin receptor in cellular membrane from hypothalamus in SHR and Wistar rats were investigated and the effect of insulin microinjection into anteri.

To examine if the glutamate receptors in the CeAare involved in this modulation, the effects of microinjection of 6-cyano-7- nitro-quinoxaline-2, 3-dione (CNQX), an AMPA receptor antagonist, into the CeAon the activities of PBN taste neurons were observed by using extracellular recording technique.
