Background
The liquid transfer device is also called a liquid transfer gun and a sample adding gun, and is a consumable precision instrument which is commonly used in a biochemical laboratory and is used for transferring liquid in a small volume.
At present, the pipettor is widely applied to clinical diagnosis laboratories, biotechnology laboratories, medicine and chemical laboratories, environmental laboratories and food laboratories. Because pipettes have different ranges and different series, in a laboratory, a laboratory worker is usually provided with five or six pipettes, so that the laboratory is an instrument which is more personalized for the laboratory worker.
In the detection process of traditional Chinese medicine detection, a liquid transfer device is required to be applied when corresponding reagents are configured. However, the liquid structure of push type is adopted to current pipettor, need squeeze the liquid in with the pipettor through user's finger extrusion and go out, move liquid volume control comparatively difficultly, the too much or too little condition of liquid volume that probably appears moving, and current pipettor structure is all comparatively single, does not have the filtering capability and gets the liquid in-process, if the detection object has flocculent deposit or dregs, when absorbing detection liquid, the flocculent in the liquid easily adsorbs on the rifle head mouth of pipettor, blocks the rifle head mouth.
Pipettes are handheld or fixed dosing devices for dosing liquids, in particular in laboratories. By "liquid" is meant a liquid medium in the form of a sample that is a single phase liquid or a liquid mixture or a multi-phase liquid mixture or a liquid-solid mixture or a liquid-gas mixture.
In the detection process of the traditional Chinese medicine, a liquid transfer device is required to be applied when corresponding reagents are prepared. However, the pipetting volume of the conventional pipettor is not easy to adjust; therefore, pipettes of different models are needed in the process of preparing corresponding reagents.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that present pipettor causes the air admission very easily when using, pollutes the interior material drawing of pipettor, is unfavorable for testing, and this application file aim at provides the pipettor that is used for chinese-medicinal material to detect, solves foretell problem.
The utility model discloses a following technical scheme realizes:
a pipettor for chinese-medicinal material detects, the terminal surface is provided with the needle bar before the handle, and the terminal surface is provided with gets the liquid head before the needle bar, set up the cavity in the handle, install the spring in the cavity, be provided with the honeycomb duct in the needle bar, honeycomb duct one end and spring coupling, the other end with get the liquid head and be connected, the honeycomb duct middle part is still connected with the gasbag through the air duct.
In traditional chinese medicinal material detects at present, the pipettor that adopts is in certain range, moves liquid from former container to a measuring tool in another container, is used for fields such as biology, chemistry extensively, and the design basis of clinical commonly used micropipette is hooke's law: that is, the length of the spring stretch is proportional to the elastic force within a certain limit, that is, the volume of the liquid in the pipette is proportional to the elastic force of the spring in the pipette, and there are two physical principles of the micropipette sample application: the micropipettes with different principles have different specific application ranges by using air cushion sample loading and piston positive movement sample loading without air cushion.
When a traditional Chinese medicine prescription is checked in a traditional Chinese medicine type pharmacy, the traditional Chinese medicine preparation is decocted according to the proportion required by the prescription, various different medicaments are formed by different decocting time and proportion, and then the medicaments are taken out by a pipettor for comparison and assay, but the traditional Chinese medicine pharmacy detects and compares suspended matters and colors by naked eye observation.
Furthermore, the rear end of the handle is provided with an anti-moving head, the cross-sectional area of the anti-moving head is larger than that of the handle, and the anti-moving head is convenient to hold the handle.
Furthermore, a switch valve is further arranged at the joint of the air duct and the air bag, a knob is arranged on the switch valve, and the switch valve is adjusted to be opened and closed through the knob.
Furthermore, the air duct adopts a hose, the cross section of the air duct is circular, and the radius of the circular cross section is at least 2 mm.
Compared with the prior art, the utility model, following advantage and beneficial effect have:
1. the utility model is used for the pipettor that the chinese-medicinal material detected, move the liquid volume through getting the control of the degree of compression of liquid head, the convenience degree is high, avoids touching the push rod unintentionally simultaneously and leads to the phenomenon of liquid blowout;
