A kind of imbibition handle
Technical field
This utility model belongs to medical equipment technical field, is specifically related to a kind of imbibition handle.
Background technology
At present, when being analyzed the research in test, it is generally adopted liquid-transfering device and measures a small amount of or trace liquid, because liquid-transfering device is higher than the precision of simple glass dropper, and it is more easy to operation, therefore this device is widely used in the fields such as chemistry, bio-pharmaceuticals, medical science.Existing shifting liquid handle cannot use medical disposable material, easily causes cross-contamination in an experiment.Accordingly, it would be desirable to improve existing shifting liquid mode, coordinate disposable suction pipette head to use on imbibition handle, reduce cross-contamination, it is ensured that the accuracy of experimental result.
Summary of the invention
The purpose of this utility model is in that to provide a kind of imbibition handle, in order to facilitates imbibition to process better, improves result of use.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of imbibition handle, including suction nozzle, suction nozzle top is provided with pushing cylinder, pushing cylinder top is provided with throw-out collar, and throw-out collar top is provided with base, and base upper right is connected to push rod, push rod top is connected to and pushes away suction nozzle button, base top is provided with slide block, is provided with pipette on the left of slide block, and pipette top is provided with flow adjustment knob;Pushing cylinder arranged outside has shell.
Having the beneficial effects that of this utility model: this utility model device can coordinate disposable suction pipette head to use effectively, improves result of use, conveniently uses as required.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described, in order to be better understood from this utility model.
Imbibition handle as shown in Figure 1, including suction nozzle 1, suction nozzle 1 top is provided with pushing cylinder 2, pushing cylinder 2 top is provided with throw-out collar 3, and throw-out collar 3 top is provided with base 4, and base 4 upper right is connected to push rod 5, push rod 5 top is connected to and pushes away suction nozzle button 7, base 4 top is provided with slide block 9, is provided with pipette 6 on the left of slide block 9, and pipette 6 top is provided with flow adjustment knob 8;Pushing cylinder 2 arranged outside has shell 10.
This utility model device in the specific implementation, is pressed and is pushed away suction nozzle button 7, pushes away suction nozzle button 7 and utilizes push rod 5 to drive base 4 to move down, and base 4 drives throw-out collar 3 to decline, and throw-out collar 3 recycles pushing cylinder 2 and promotes suction nozzle 1, makes suction nozzle 1 eject.Base 4 is provided with spring, can automatically reset.Rotary current adjusting knob 8, it is possible to control the speed of imbibition.Flow adjustment knob 8 has wheel, reduces frictional force during extrusion pipe.There is no the risk of leakage, easy to maintenance.Pipette 6 is directly connected with liquid containing bottle, can sucking liquid continuously.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
