Ground, is provided with diversion pipe 30 between pipette 23 and liquid supply pipe 13, control mechanism 40 is set on diversion pipe 30.
It should illustrate: since the pressure oscillation in pipette 23 affected by environment is larger, and the pressure base in liquid supply pipe 13
Originally it remains unchanged, therefore, above-mentioned set pressure differential determines that the negative pressure value should be unlikely according to the negative pressure value in pipette 23
In the peak suction value for making tissue based on the reason of mentioned in background technique and damaging.That is, when in pipette 23
Negative pressure to when being more than the degree that tissue may be made to be damaged, control mechanism 40 connects liquid supply pipe 13 and pipette 23
It is logical.
The working principle of the above embodiment of the present invention are as follows:
As shown in Figure 1, need when being suctioned to tissue, using solution feed pump 12, via liquid supply pipe 13 and nozzle to tissue
Spray into cleaning solution, meanwhile, using suction pump 22, and by fluid suction head 24 and pipette 23 by used cleaning solution flow back in
Liquid-return box 21.
As shown in figure 3, when fluid suction head 24 is instantaneously inhaled because uncontrollable movement or cleaning solution occurs a certain substantially
The reason of walking and cause fluid suction head 24 mainly in draw gas, and the power of suction pump 22 increases and causes negative in pipette 23
When pressure degree is more than maximum allowable negative pressure value, control mechanism 40 is connected to pipette 23 with liquid supply pipe 13, so that feed flow
Cleaning solution in pipe 13 is at least part of into the negative pressure for compensating pipette 23 in pipette 23, so that negative in pipette 23
Pressure remain more constant, and then can effectively prevent because in pipette 23 reduced pressure it is excessive due to damage tissue.
As shown in figure 4, being blocked when fluid suction head 24 is contacted with tissue, so that either cleaning solution or gas all can not
Into pipette 23, and when suction pump 22 makes the reduced pressure in pipette 23 be more than maximum allowable negative pressure value, control mechanism
40 are connected to pipette 23 with liquid supply pipe 13, so that the cleaning solution in liquid supply pipe 13 is at least part of to enter pipette 23
In to compensate the negative pressure of pipette 23 so that the negative pressure in pipette 23 remains more constant, so can effectively prevent because
Reduced pressure is excessive and damage tissue in pipette 23.
The advantage of the above embodiment of the present invention is:
The present invention controls the control mechanism 40 of the on-off of liquid supply pipe 13 and pipette 23, energy by being arranged according to pressure difference
Enough effectively prevent because in pipette 23 reduced pressure it is excessive due to cause damage tissue the case where generation.
In a preferred embodiment of the invention, such as Fig. 2 and as shown in connection with fig. 1, control mechanism 40 include: cylinder 41,
Piston 42, baffle ring 44, backstop set 45.Directed cavity 411, the first end and second end point of directed cavity 411 are offered in cylinder 41

43 are set in directed cavity 411 to push against piston 42.Wherein: the first end of directed cavity 411 is provided with baffle ring 44, for only
Keep off piston 42；Backstop set 45 is set in directed cavity 411, and spring 43 is set between backstop set 45 and piston 42.Directed cavity 411
Cavity wall on offer diversion trench 412, diversion trench 412 extends one section along the glide direction of piston 42, and diversion trench 412 is circumferentially
Have a plurality of；Spring 43 pushes against piston 42 so that piston 42 is blocked by the cooperation of the cavity wall with directed cavity 411 close to directed cavity
The end of the diversion trench 412 of 411 first end.
The working principle of control mechanism 40 provided by above-described embodiment:
Such as Fig. 2 and as shown in connection with fig. 1, when the reduced pressure in pipette 23 is less than maximum allowable negative pressure value, at this point,
Pressure difference between liquid supply pipe 13 and pipette 23 does not exceed set pressure differential, at this point, under the action of spring 43, piston 42
Against baffle ring 44, which is located at most side shown in the drawings, at this point, the matching by the cavity wall with directed cavity 411 of piston 42
The end of the diversion trench 412 of the first end close to directed cavity 411 is closed and blocked, and makes 13 cleaning solution of liquid supply pipe will not be by leading
Chute 412 enters liquid supply pipe 13.
And when the reduced pressure in pipette 23 is more than maximum allowable negative pressure value, between liquid supply pipe 13 and pipette 23
Pressure difference is greater than set pressure differential, as shown in figure 5, at this point, the pressure of the cleaning solution in liquid supply pipe 13 overcomes 43 power of spring, and make
Piston 42 is mobile towards right side shown in the drawings, and then opens the end of diversion trench 412, this makes cleaning solution by diversion trench
412 and the directed cavity 411 on the right side of piston 42 enter to compensate the negative pressure in pipette 23 in pipette 23, and then reduce imbibition
Reduced pressure in pipe 23, and when the reduced pressure in pipette 23 is reduced to permissible value or less, spring 43 makes piston again
42 block the end of diversion trench 412 again.
It should illustrate:
1, because under normal circumstances, also having certain pressure poor between liquid supply pipe 13 and pipette 23, therefore, it is necessary to be arranged
The elastic force of spring 43, so that piston 42 has certain pretightning force to baffle ring 44 when not carrying out washing and cleaning operation.
2, the elastic force of spring 43 needs the maximum allowable negative pressure according to pipette 23 to determine.
In a preferred embodiment of the invention, as shown in figure 5, the end of diversion trench 412 forms changeover portion 4121, make
It obtains in diversion trench 412 as the movement of piston 42 is gradually opened, until fully opening.The advantage of such setting is: working as suction
When passing through cleaning solution and gas in liquid pipe 23 simultaneously, when so that negative pressure increasing and is unlikely to excessive, diversion trench 412 will not be beaten completely
It opens, it is therefore an objective to less amount of cleaning solution only be allowed to enter the increasing that pipette 23 is only used for loading level brought by compensation gas
Greatly, this certainly will save cleaning solution.
