Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, this embodiment provides a liquid dispenser for distributing the same liquid into multiple containers through the liquid dispenser. The liquid dispenser includes a liquid dispenser housing 1 provided with a cavity 11, and the liquid dispenser housing 1 is provided with a liquid inlet 12 and a plurality of liquid outlets 13; the liquid inlet 12 and the liquid outlet 13 Both are in communication with the cavity 11; the housing 1 of the liquid dispenser is also provided with a positioning piece 15, which is used for the positioning of the liquid dispenser and the porous plate to be liquid-separated.

[0027] By providing multiple liquid outlet holes 13, liquid can be added to multiple holes on the perforated plate at the same time. The liquid separator has a simple structure, is easy to process, has low production cost, and improves liquid separation efficiency. In this embodiment, the liquid outlet holes 13 are distributed in fou...

Embodiment 2

[0037] Such as image 3 As shown, in this embodiment, on the basis of the first embodiment, a filter device 2 is added in the cavity 11 for filtering the liquid that will flow out through the liquid outlet hole 13 .

[0038] Specifically, the liquid inlet hole 12 and the liquid outlet hole 13 are respectively located on both sides of the filter device 2; the cavity 11 is divided into upper and lower chambers by the filter device 2, so that the liquid enters the upper chamber through the liquid inlet hole 12. In the chamber, the liquid enters the lower chamber after being filtered by the filter device 2 , and then flows out through a plurality of liquid outlet holes 13 . Using the filter device 2 to filter the liquid can prevent the liquid entering the holes on the perforated plate from being polluted when the liquid flowing out through the liquid outlet hole 13 contains impurities.

[0039] The filter device 2 includes a filter plate 21 detachably connected to the liquid sepa...

Embodiment 3

[0044] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, a liquid outlet pipe 14 extends downward from the bottom of the liquid outlet hole 13 , and the inner diameter of the liquid outlet pipe 14 is the same as that of the liquid outlet hole 13 . By setting the liquid outlet pipe 14, it is convenient to make the liquid outlet pipe 14 correspond to the corresponding holes on the perforated plate one by one, ensuring that the liquid flowing out from the liquid outlet hole 13 will not flow to the hole on the perforated plate corresponding to the adjacent liquid outlet hole 13 Inner or perforated plate.

[0045] The liquid outlet pipe 14 is integrally formed with the liquid distributor housing 1, which can simplify the structure of the liquid distributor, simplify the processing technology and reduce the production cost. The liquid outlet pipe 14 and the liquid separator housing 1 are integrally molded by mold integra...

Abstract

The invention belongs to the field of biological medicine apparatus, and more specifically discloses a liquid dispenser. The liquid dispenser comprises a liquid dispenser housing provided with a cavity; the liquid dispenser housing is provided with one liquid inlet and a plurality of liquid outlets; the liquid inlet and the liquid outlets are communicated with the cavity; the liquid dispenser housing is provided with a positioning part; the positioning part is used for positioning cooperation of the liquid dispenser with a porous plate for liquid dispensation. The plurality of liquid outlets are adopted, so that liquid can be introduced into a plurality of pores on the porous plate at the same time; the liquid dispenser is simple in structure, is convenient for processing, is low in production cost; compared with adding of liquid into each pore of the porous plate using a pipette, the liquid dispenser possesses following advantages: liquid dispensation time is shortened; liquid dispensation efficiency is increased; positioning cooperation of the liquid dispenser with the porous plate is realized using the positioning part; the liquid dispenser is driven to slide so as to realize alignment of the liquid outlets with corresponding pores on the porous plate, a problem that not all of liquid flows out from the liquid outlets is introduced into the corresponding pores on the porousplate is avoided, requirements on operators are reduced, and operation flow is simplified.

Description

technical field [0001] The invention relates to the field of biomedical devices, in particular to a liquid dispenser. Background technique [0002] In biological experiments, liquid transfer and dispensing operations are usually encountered. For example, in neurobiology, brain slices are usually stained multiple times. In this process, liquids need to be poured out and added repeatedly. The above Decanting and adding liquids often require the use of multi-well plates. Among them, the porous plate is a kind of liquid separation container often used in biological experiments. When adding liquid to each well of the porous plate, it is necessary to add liquid to the wells of the porous plate one by one through a pipette gun, which is time-consuming and laborious. , the separation efficiency is low. [0003] In order to solve the above problems, liquid dispensers are usually used in the prior art to add liquid to multiple holes on the porous plate at one time. For the liquid d...
