Abstract
The invention discloses an upper mechanism for a full-automatic tubular chemiluminescent analyzer. The upper mechanism comprises a bracket, a sampling needle and a transmission part, wherein the transmission part drives the sampling needle to realize movement in the X, Y or Z direction, and the sampling needle comprises a Z-axis steel pipe, a Z-axis steel pipe joint and a substitution head. The upper mechanism has the beneficial effects that a feeding needle in the traditional design is replaced by employing the disposable substitution head, each substitution head can be used only one time, a cross contamination phenomenon caused by the condition that the feeding needle is not cleaned in the prior art is effectively avoided, and the accuracy of absorbing the substitution head through the sampling needle is guaranteed through the Z-axis sensor joint; and moreover, the sampling needle which can independently move in three directions has the advantages of high working efficiency, high degree of automation and low application cost.
Description
Technical field
The present invention relates to the chemiluminescence field, especially relate to a kind of full-automatic tubular type chemiluminescent analyzer upper mechanism.
Background technology
In the chemiluminescence analytical technique field, chemiluminescence immune assay system etc. carries out biochemical reaction by sample needle draw samples and all ingredients, sample needle is when extracting testing sample and all ingredients, sample needle can produce cross pollution to sample and reagent, for reducing cross pollution, sample needle can not enter in sample cup or the reagent cup too dark under stepper motor drives, and need control sample needle and stop to continue to descend and beginning draw samples or reagent when sample needle touches liquid level.As mentioned above, even have under the prerequisite of liquid level sensor, still there are following two shortcomings in this upper unit that uses in the prior art: 1) inevitably there is cross pollution in the sample needle that can repeatedly use repeatedly; 2) used two sample needles, two sample needles can cause the cross pollution between sample and reagent, and control is complicated, and the danger that has two pins to collide mutually.
Summary of the invention
The objective of the invention is to overcome the shortcoming that exists in the prior art, the sampling probe that provides a kind of use to have substitute head adds the full-automatic tubular type chemical analyzer upper unit that reagent and sampling probe are finished the interpolation of different reagent, no striker danger, the technical scheme that adopts is: a kind of full-automatic tubular type chemiluminescent analyzer upper mechanism, comprise support, it is characterized in that: described upper mechanism also comprises sampling probe and drives the drive disk assembly that sampling probe realizes that X, Y or Z direction move that sampling probe comprises the coupling of Z axle and substitute head.
The solution of the present invention also has: described drive disk assembly comprises X-axis drive disk assembly, Y-axis drive disk assembly and Z through-drive parts, and wherein Z through-drive parts comprise Z axial filament thick stick and Z spindle nut, and described Z spindle nut is positioned on the needle stand.
The solution of the present invention also has: described X-axis drive disk assembly comprises that X-axis is with synchronously and the X-axis power part of the synchronous Tape movement of drive X-axis.
The solution of the present invention also has: described Y-axis drive disk assembly comprises that Y-axis is with synchronously and the Y-axis power part of the synchronous Tape movement of drive Y-axis.
Beneficial effect of the present invention is: the present invention has adopted disposable substitute head to replace the sample needle in the traditional design, each substitute head only uses once, effectively avoided the cleaning dirty cross pollution phenomenon that causes of sample needle in the conventional art, Z axle sensor joint piece has guaranteed the accuracy of sampling probe absorption substitute head; But the sampling probe of three equal self-movements of direction has high efficiency, automaticity height, the advantage that application cost is cheap.
Description of drawings
Accompanying drawing 1 is perspective view of the present invention, and accompanying drawing 2 is front views of accompanying drawing 1, and accompanying drawing 3 is left views of accompanying drawing 1, and accompanying drawing 4 is A-A views of accompanying drawing 3, wherein 1 is the substitute head, the coupling of the 2nd, Z axle, the 3rd, Z axle steel pipe, the 4th, liquid level detection device, the 5th, Z axle sensor joint piece, the 6th, needle stand.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.The invention discloses a kind of full-automatic tubular type chemiluminescent analyzer upper mechanism, comprise that support, sampling probe and drive sampling probe realize the drive disk assembly that X, Y or Z direction move, sampling probe comprises Z axle steel pipe 3, Z axle coupling 2 and substitute 1.Wherein, substitute 1 is the changeable type head of substituting.Between Z axle coupling 2 and Z axle steel pipe 3, also be provided with and play the liquid level detection device 4 that detects liquid level.Drive disk assembly comprises X-axis drive disk assembly, Y-axis drive disk assembly and Z through-drive parts, and wherein Z through-drive parts comprise Z axial filament thick stick and Z spindle nut, and the Z spindle nut is positioned on the needle stand.When Z axial filament thick stick rotated, drive Z spindle nut and the needle stand that is fixed on the Z spindle nut realized that Z-direction moves up and down.The X-axis drive disk assembly comprises that X-axis is with synchronously and the X-axis power part of the synchronous Tape movement of drive X-axis.Under the X-axis power part drove, X-axis was with synchronously and is realized that X axis moves, and then realized that the X axis of sampling probe moves.The Y-axis drive disk assembly comprises that Y-axis is with synchronously and the Y-axis power part of the synchronous Tape movement of drive Y-axis.Under the Y-axis power part drove, Y-axis was with the realization Y-axis synchronously, and then realized that the y-axis shift of sampling probe is moving.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also belong to protection scope of the present invention.
