Embodiment
The utility model provides a kind of preheating apparatus of reagent fast, and the reagent that solves on the automatic biochemistry analyzer preheats demand, can be heated rapidly to design temperature by the reagent that temperature is lower, satisfies test request.
As shown in Figure 1, the reagent preheating apparatus comprises: the preheating urceolus 1 for drum, inlet 11 is set on the one end, and the other end is provided with cover plate 3, by this cover plate 3 preheating urceolus 1 is sealed, and on this cover plate 3 liquid outlet 31 is set; Be arranged on the mandrel 2 of preheating urceolus 1 inside, continuous helicla flute 21 is set on the external cylindrical surface of this mandrel 2; In addition, be arranged on heating rod 41, overheat switch 42 and the temperature sensor 43 of preheating urceolus 1 inside, this heating rod 41, overheat switch 42 and temperature sensor 43 all from the cover plate 3 a plurality of jacks of relative set be inserted into preheating urceolus 1 inside respectively.
In conjunction with shown in Figure 2, the mandrel 2 wherein center of an end face is provided with 2 end faces that this center pit 23 of center pit 23(can run through mandrel 2), this center pit 23 is used to hold heating rod 41, and the aperture shape of center pit 23 matches with xsect external diameter size with the shape of heating rod 41 with size, makes heating rod 41 have heat-conductive characteristic preferably with mandrel 2 tight attachings; In addition, have at mandrel 2 on the end face of center pit 23, two accommodation holes 22 and 24 are set, be respectively applied for laying temperature sensor 43 and overheat switch 42, wherein, accommodation hole 22 is a square groove.
After heating rod 41, overheat switch 42 and temperature sensor 43 passed jack on the cover plate 3 respectively, heating rod 41 was placed in the center pit 23 of mandrel 2, and overheat switch 42 and temperature sensor 43 are placed on respectively among the accommodation hole 24 and 22 of mandrel 2; And the teflon pipe that is loaded with reagent twines in the helicla flute 21 that is arranged on mandrel 2 external cylindrical surfaces, and mandrel 2 is put into preheating urceolus 1 inside, is fixed on preheating urceolus 1 inside by cover plate 3 with 1 sealing of preheating urceolus and with mandrel 2.
In test process, an end of teflon pipe is arranged at the inlet 11 of preheating urceolus 1, and the other end is arranged on the liquid outlet 31 on the cover plate 3, and reagent enters from inlet 11 by teflon pipe, through the heating of preheating apparatus, from liquid outlet 31 outputs.
