Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

As illustrated, the syringe drop microscope in the utility model, including base 5, the laser that is arranged on base 5 Support 2 and syringe rack 4, the laser pen support 2 are provided with the laser pen 1 for outgoing parallel laser light beam 1-4, institute Syringe rack 4 is stated provided with the syringe 3 of drop globe lens can be formed；The parallel laser light beam 1-4 of the outgoing of laser pen 1 Through drop globe lens center.

Specifically, laser pen 1 is fixed on laser pen support 2, syringe 3 is fixed on syringe rack 4, two stands with Base 5 is connected.Syringe 3 is mainly made up of piston core pin 3-1, injection needle tube 3-2 and nipple 3-3, pushing syringe piston core Bar 3-1, makes to hang drop 3-4 at syringe nipple 3-3, drop is spherical in shape due to surface tension, can be used as higher magnification Globe lens use, regulation laser pen 1 position makes the parallel laser light beam 1-4 of its outgoing pass through drop globe lens center, in liquid The hot spot of amplification can be presented on drop rear portion screen, when being mixed with cell in drop, the cell picture of Observable amplification.Pass through injection Device applies different pressures, adjusts the shape of liquid lens, that is, adjusts the radius of curvature of liquid lens, reach different multiplication factors And observation effect.

In the present embodiment, as shown in figure 1, syringe drop microscope is by main part, fixed support and base portion structure Into main part includes syringe 3 and laser pen 1.Fixed support is by relatively low laser pen support 2 and higher syringe rack 4 Constitute, two stands top is clamped laser pen 1 and syringe 3 by annular groove, is locked after clamping by jackscrew respectively, two Cantilever tip annular groove can rotate regulation by rotating shaft around cantilever tip, so as to drive laser pen 1 and syringe 3 to carry out respectively Pitch regulation.Laser pen support 2 and the bottom of syringe rack 4 are stably connected with base 5.Base 5 herein uses aluminium alloy Material, steadily of centre of gravity；Certainly, it can also be made up, or be made up of nonmetallic materials 3D printing of other metal materials.

As shown in Figure 2, the syringe 3 in the present embodiment uses medical 2ml syringes, by with syringe nipple 3-3's Injection needle tube 3-2 and piston core pin 3-1 are constituted, and promote the handle of piston core pin, and piston is by the liquid of injector syringe forward end seal Body releases syringe nipple 3-3, forms drop 3-4 and is suspended on injector syringe nipple tip.

As shown in Figure 3, laser pen is by the green semiconductor laser 1-1 of 532nm, two No. 7 supplying cell 1-2 of section and laser Pen switch 1-3 compositions, binding post is connected by wire between supplying cell, switch and laser, and it is near that laser pen 1 sends light beam 1-4 It is seemingly collimated light beam.Certainly, laser is sent wavelength or 633nm red, 610nm orange, 585nm yellow or 450nm Blueness, can also use solid state laser.

Piston core pin 3-1 is promoted, is mixed with before the liquid of cell is pushed to syringe nipple 3-3 and brings out in injection needle tube 3-2 Mouthful, drop 3-4 is constituted, laser pen switch 1-3 is pressed, two save No. 7 supplying cell 1-2 powers to semiconductor laser 1-1, laser Pen launches the green collimated light beam 1-4 of 532nm.As shown in figure 4, regulation laser pen support 2 and the luffing angle of syringe rack 4, Collimated laser beam 1-4 is set to inject in the middle part of drop 3-4, it can be seen that laser beam amplification hot spot and liquid on the metope of drop globe lens rear portion The enlarged drawing of the internal cell of drop.

Finally illustrate, preferred embodiment above is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent The utility model is described in detail by above preferred embodiment for pipe, but those skilled in the art should manage Solution, can make various changes, without departing from the utility model claims institute to it in the form and details The scope of restriction.
