Abstract
Manual liquid transfering device is related to medical instruments field, solves the problems, such as that the speed of suction ball sample-adding is difficult to control and accuracy is insufficient.The pipette includes suction ball, suction pipe, interface, is provided with exhaust outlet at the top of suction ball, further includes drawing the switch of liquid and the ball valve of speed for controlling, for preventing excess liq from entering the bursting tube of ball valve；Suction ball, ball valve, interface, bursting tube and suction pipe are sequentially connected with.The control of control and capture velocity whether the utility model is drawn using ball valve, can be drawn with different capture velocities.Bursting tube is set between ball valve and suction pipe, and to prevent excessive liquid from entering ball valve and suction ball, liquid caused by also reducing because of misoperation enters the probability of sphere.By ball valve and suction ball, realizes to discharge and realize speed and flux with control when inhaling liquid in pipe.And structure is simple.It can be applied in physico-chemical analysis experiment.
Description
Technical field
The utility model relates to medical instruments fields, in particular to Manual liquid transfering device.
Background technique
The method that suction ball cooperation suction pipe is generally used when physico-chemical analysis personnel pipette various testing reagents, microorganism is examined at present
The suction ball that the personnel of testing use, but only suction ball is not easily controlled imbibition flow velocity, influences the speed and accuracy of sample-adding.
Utility model content
In order to solve the problems, such as that the speed of suction ball sample-adding is difficult to control and accuracy is insufficient, the utility model provides a kind of hand
Dynamic pipettor.
The utility model technical scheme applied to solve the technical problem is as follows:
Manual liquid transfering device, including suction ball, suction pipe, interface, suction ball top are provided with exhaust outlet, further include drawing for controlling
The switch of liquid and the ball valve of speed, for preventing excess liq from entering the bursting tube of ball valve；Suction ball, ball valve, interface, bursting tube
It is sequentially connected with suction pipe.
The ball valve uses soft sealing ball valve.
The ball valve uses V-type ball valve.
The beneficial effects of the utility model are: the utility model structure is simple, control whether absorption using ball valve
With the control of capture velocity, can be drawn with different capture velocities.Bursting tube is set between ball valve and suction pipe, to prevent
Excessive liquid enters ball valve and suction ball, and liquid caused by also reducing because of misoperation enters the probability of ball valve.By ball valve with
Suction ball is realized to discharge and realizes speed and flux with control when inhaling liquid in pipe.
Detailed description of the invention
The structure chart of Fig. 1 the utility model Manual liquid transfering device.
Wherein, 1, suction ball；2, ball valve；3, suction pipe；4, interface；5, bursting tube.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
Manual liquid transfering device, as shown in Figure 1, including suction ball 1, ball valve 2, interface 4, bursting tube 5 and suction pipe 3,1 connected ball of suction ball
Valve 2, ball valve 2 are connect with bursting tube 5 by interface 4, the other end connected sucking pipe 3 of bursting tube 5.Ball valve 2 is for controlling the suction of suction ball 1
The switch and capture velocity of liquid are taken, the setting of bursting tube 5 is among suction pipe 3 and ball valve 2, for preventing excess liq from entering ball valve
2 with suction ball 1, and liquid caused by also reducing because of misoperation enters the probability of ball valve 2.It wherein is provided with exhaust outlet at the top of suction ball 1,
Suction pipe 3 can be replaced, and bursting tube 5 can also be replaced, and bursting tube 5 can also take off cleaning to reuse.
Opening ball valve 2, the flow velocity of adjustment ball valve 2 to demand, suction pipe insertion liquid internal, appropriate power pinching suction ball 1,
Under the action of air pressure, liquid is entered in suction pipe 3, and suction pipe 3 has scale, can be adjusted ball valve 2 according to demand at this time, is drawn to institute
It needs the liquid of volume to reach appropriate scale, closes ball valve 2 immediately, open exhaust outlet, restore to the original state to suction ball 1, open ball valve 2
The liquid in suction pipe 3 is discharged, the outflow flux of liquid, pinching suction ball 1 control in the openings of sizes control suction pipe 3 of adjustment ball valve 2
The rate of outflow of liquid in suction pipe 3 realizes that rate of release and flux discharge process with the liquid of control.
