Description
Technical Field
The utility model relates to the field of biological experiment equipment, in particular to a novel puncture needle head for an injector.
Background
The needles matched with the currently used syringes are all cylindrical metal needles which can directly puncture the skin or a bottle mouth plug. In biological experiments, many bottled reagents cannot be used at one time, and need to be drawn out by a syringe for multiple times and then injected into other bags or bottles. When the reagent in the bottle is pumped out, the pressure in the bottle becomes small, so that the liquid is difficult to be pumped out. The novel puncture needle head can effectively solve the problem that liquid is difficult to extract.
At present, reagents are extracted in experiments mainly by using a syringe with brute force. Or when the reagent is purchased, the reagent in the plastic bag is selected, and the problem of negative pressure is solved through deformation of the bag. Still further, the cap needs to be opened and the contents dispensed by pipette into a centrifuge tube or bottle.
The utility model aims at solving the problem that the negative pressure generated in the bottle leads to the difficulty of reagent extraction when the reagent is extracted by the injector.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to extract reagent in the experiment at present, mainly lean on the syringe to use brute force extraction.
