Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, be the schematic appearance of the utility model micro liquid sampling sample adding device, it comprises a sampling head 1, liquid storage pipe 3 and a feed head 7.As shown in Figure 3, quantitative capillary tube (not marking in figure) is connected with in one end of sampling head 1; As shown in Figure 2, diaphragm seal 2 is sealed with in one end of liquid storage pipe 3, and this end connects a ring bodies (not marking in figure), one end of this ring bodies and liquid storage pipe 3 forms a boss 8, sampling head 1 can match with one end of liquid storage pipe 3, when matching, sampling head 1 can offset with boss 8, and then it is spacing to realize between sampling head 1 and liquid storage pipe 3.When sampling head 1 matches with liquid storage pipe 3, the quantitative capillary tube on sampling head 1 punctures diaphragm seal 2 and extends in the cavity of liquid storage pipe 3.In addition, the inwall of the ring bodies be connected with liquid storage pipe 3 is provided with multiple circular protrusion I 5, it has the effect preventing the liquid in liquid storage pipe 3 from flowing out.The other end of liquid storage pipe 3 matches with feed head 7, and feed head 7 can move along the length direction of liquid storage pipe 3, and on the inwall of liquid storage pipe 3, be provided with multiple circular protrusion II 6, as shown in the partial enlarged drawing in Fig. 2, it has the effect preventing feed head 7 from coming off from liquid storage pipe 3.
For the ease of application of sample, the cavity of feed head 7 is arranged to by its one end to its endpiece form from large to small, as shown in Figures 2 and 3, by heavy caliber end to small-caliber end, this feed head 7 is successively by right cylinder a, Rotary-table and right cylinder b form, be connected with the heavy caliber end of Rotary-table by right cylinder a, the small-caliber end of Rotary-table and being connected of right cylinder b, when application of sample, when feed head 7 is moved to the other end of liquid storage pipe 3, liquid then in liquid storage pipe 3 is compressed, pressure increase, the cavity of feed head 7 above-mentioned is provided with and helps liquid and flow out from its endpiece.
Use procedure the following detailed description of the utility model micro liquid sampling sample adding device is described:
When needing the sampling carrying out micro liquid, utilize siphonage pipette samples with the quantitative capillary tube of sampling head 1, the size of different kapillaries can be used for the micro liquid drawing different volumes.After quantitative capillary tube has drawn sample, puncture liquid storage pipe 3 top closure film 2 with it and make the middle part of sampling head 1 be sealed in the liquid storage cylinder 4 of liquid storage pipe 3, and sampling head 1 and the boss 8 on liquid storage pipe 3 offset, what realize between sampling head 1 and liquid storage pipe 3 is spacing, and the circular protrusion I 5 on ring bodies coordinates with sampling head 1 and prevents the interior liquid in liquid storage cylinder 4 from flowing out.The downward whipping of hand-held liquid storage pipe 3 the first half, makes the sample in quantitative capillary tube enter in liquid storage cylinder 4, and then turn upside down this micro liquid sampling sample adding device, reaches the effect of reagent mixing in got micro-example and liquid storage cylinder; Or by feed head 7 with liquid storage pipe 3 reciprocal relative movement to reach the effect of liquid blending.
When the utility model is used for application of sample, hold sampling head 1 and liquid storage pipe 3 promotion feed head 7 downwards, then feed head 7 moves to the inside cavity of liquid storage pipe 3, and liquid storage cylinder 4 is reduced gradually, and in liquid storage cylinder 4, reagent is extruded liquid storage cylinder 4 simultaneously, and then completes application of sample.
