Background technology
At hospital clinical check, isotope, putting and exempt from, and in the enterprises and institutions such as R&D institution or relevant chemical industry, food, mine, do experiment and sample, often need move liquid with pipette or suction pipe, is a kind of indispensable experiment appliance.Detailed directions is exactly rubber pipette bulb to be placed on to the top of pipette, and extruding rubber pipette bulb, is drawn onto liquid in pipette, blocks above pipette, then liquid is wherein put into and wanted the vessel put into finger.Extracting in mobile waywardly like this, moving liquid speed slower, and in checkout procedure, push rubber pipette bulb and easily cause sample microbial contamination, affect experiment effect, therefore need to design a set of stable, safely, fast, device is realized this purpose easily.
As notification number is: the disposable plastic pipette that the Chinese utility model patent of CN2275902Y provides, by liquid storage tube and suction ball, formed, the liquid storage tube made from plastics and suction ball are an integral body.Its so-called liquid storage tube can be made into extra heavy pipe or elongated tubular or miniature tube, and Guan Shangke has scale, also can be without scale.Its so-called suction ball is the various shapes such as cylindrical or spherical or elliposoidal.This pipette just exists that to move liquid speed slow, easily causes sample microbial contamination, affects the problem of experiment effect.
Utility model content
The utility model is mainly slow for the existing liquid speed of moving of existing pipette, easily causes the problem of sample microbial contamination, provides a kind of easy to use, can effectively prevent the experiment liquid-transfering device of sample contamination.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of experiment liquid-transfering device, it comprises suction pipe, one end of suction pipe is provided with suction nozzle, the other end is provided with rubber suction nozzle, between suction pipe and rubber suction nozzle, be provided with purifier, described purifier comprises the large footpath section being connected with rubber suction nozzle and the path section being connected with suction pipe, large footpath section is with path section removably connects and large footpath section and path section surround purification chamber, suction pipe and rubber suction nozzle are all communicated with purification chamber, purify in chamber and be provided with two filter screens, between two filter screens, be filled with medical absorbent cotton.Extruding rubber suction nozzle can make liquid self-absorbing mouth suck in suction pipe, again liquid is put into and wanted the vessel put into, the medical absorbent cotton purifying in chamber has sterilization effect, medical absorbent cotton is high temperature resistant, be convenient to autoclaving, can prevent liquid microbial contamination, and the solids precipitation thing in can filter liquide.
As preferably, the inwall of described large footpath section is covered with internal thread, and the outer wall of path section is covered with external screw thread, and large footpath section is threaded with path section.Technology maturation, firm and reliable connection.
As preferably, in described purification chamber, be provided with sealing ring, path section is resisted against on sealing ring and with large footpath section and is connected.Sealing ring, for improving large footpath section and the sealing that path section is connected, prevents from leaking.
As preferably, described path section is provided with the transition shaft shoulder of ring-type, and the bottom of large footpath section is resisted against on the transition shaft shoulder.The transition shaft shoulder plays positioning supports effect, prevents Overexertion, and large footpath section is damaged.
As preferably, described suction nozzle is tapered, the smooth surface that the outer surface of suction nozzle is indent.Suction nozzle is the pyramidal structure of indent, reduces to interfere, and is convenient to washing lotion.
As preferably, described suction pipe is provided with graduation mark.Metering to liquid while being convenient to extract.
Therefore, the beneficial effects of the utility model are: between suction pipe and suction nozzle, set up purifier, in purifier, increase medical absorbent cotton, by medical absorbent cotton, liquid is filtered and sterilization, easy and simple to handle, move liquid velocity and guarantee that soon, flexibly Micro biological Tests completes check within effective time, prevent that Check-Out Time is long and cause sample contamination.
