Embodiment
Novel hand held microplate reader as described in Figure 2 comprises shell 21, and testing agency and feed mechanism are installed in the shell 21, has perforation 22 on the described shell 21, and described feed mechanism is to be located at the screens assembly that perforation 22 content enzymes mark bar 3 single-frame advances and locatees.
Wherein, enzyme mark bar 3 is by the strip container of row's reagent lattice 32 one injection mouldings, has the depression 31 that plays the role of positioning in the both sides of enzyme mark bar 3.
The multiple version that can adopt described screens assembly realizes enzyme mark bar 3 single-frame moving and the location under manual condition.The various versions of screens assembly are described below by specific embodiment:
As shown in Figure 3, this is implemented described screens assembly and comprises substrate 41, two blocks of side plates 42, two location 43, two springs of hoodle (invisible among the figure), a baffle plate 45.
Wherein, two side plate 42 fixed interval form pedestal on substrate 41, and the interval between the biside plate 42 has formed enzyme mark bar passage 46, and the width of this enzyme mark bar passage 46 is slightly larger than the width of enzyme mark bar.The side direction of a side plate therein has two holes 47, distance between two holes 47 should be suitable with the distance marked between the adjacent reagent lattice center of bar of enzyme, be equipped with a location hoodle 43 and a spring in the hole 47, location hoodle 43 is positioned at enzyme mark bar passage 46 sides, spring is positioned at relative enzyme mark bar passage 46 sides to be replaced and locatees hoodle, and baffle plate 45 is blocked hole 47 from the outside fixed sealing of side plate 42.Hole 47 is positioned at the aperture of enzyme mark bar passage 46 sides should be less than the diameter of location hoodle 43, be positioned at the diameter of the aperture of relative enzyme mark bar passage 46 sides greater than location hoodle 43, the location hoodle 43 so that can pack into, and after packing into, location hoodle 43 is unlikely to from hole 47, to slide out, make location hoodle 43 under the replacing of spring, part is exposed in the enzyme mark bar passage 46.
Adopt said structure, the reagent lattice of enzyme mark bar 3 push the location hoodle 43 that touches at first under the hand push effect, make in the hoodle 43 retraction holes 47, location, reagent lattice that hold enzyme mark bar pass through, after the reagent lattice pass through, the reagent lattice are just in time between two location hoodles, original location hoodle 43 that is compressed in the hand-hole 47 restores again under the effect of spring restoring force, just in time get back in the depression 31 of enzyme mark bar side, position thereby be implemented between two location hoodles, at this moment, the testing agency of hand held microplate reader will detect the reagent in the reagent lattice, so, thus realize that the hand held microplate reader is to the single-frame detection of enzyme mark bar under the hand push condition.
As shown in Figure 4, the described screens assembly of present embodiment comprises substrate 41, two blocks of side plates 42, a spring 48.Two side plate 42 fixed interval form pedestal on substrate 41, the interval between the biside plate 42 has formed enzyme mark bar passage 46, and the width of this enzyme mark bar passage 46 is slightly larger than the width of enzyme mark bar.Spring 48 is bent into the screens portion that stops with two ridges 481, and the distance between two ridges, 481 centers between distance and the enzyme mark bar reagent lattice center is suitable.Have along the slot 461 of enzyme mark bar channel direction on enzyme mark bar passage 46 sidewalls, spring 48 is embedded in the slot 461, stops that screens portion is exposed in the enzyme mark bar passage 46.
Equally, the reagent lattice of enzyme mark bar push the screens portion that stops under the hand push effect, to stop that the reagent lattice that screens portion is pressed into slot 461 content enzymes marks bar pass through, when the reagent lattice pass through ridge, arrive the recessed position between the ridge, original being compressed as deciding in the side plate 42 stops that screens portion restores again under spring 48 restoring force effects, just in time again enzyme mark bar is blocked, thereby realize the location of enzyme mark bar reagent lattice, at this moment, the testing agency of hand held microplate reader will detect the reagent in the reagent lattice, so, thereby realizes that the hand held microplate reader is to the single-frame detection of enzyme mark bar under the hand push condition.
As shown in Figure 5, the described screens assembly of present embodiment comprises substrate 41, two blocks of side plates 42.Two side plate 42 fixed interval form pedestal on substrate 41, the interval between the biside plate 42 has formed enzyme mark bar passage 46, and the width of this enzyme mark bar passage 46 is slightly larger than the width of enzyme mark bar.Wherein enzyme mark bar passage 46 1 sidewalls (promptly on the side plate 42 therein) have the elongated slot 462 that extends along enzyme mark bar passage 46 directions.Have long lath 49 in the elongated slot 462, an end of this long lath 49 is stuck on the side plate 42, and the side that the other end is positioned at enzyme mark bar passage 46 directions has the circular arc screens projection 491 that is exposed at enzyme mark jumping passage.
Equally, the reagent lattice of enzyme mark bar push long lath 49 under the hand push effect circular arc screens projection 491, make long lath 49 to the groove inner bending, the reagent lattice that circular arc screens projection 491 are pressed into groove content enzyme mark bar pass through, after the reagent lattice pass through, long lath 49 is replied under himself toughness effect and is made circular arc screens projection 491 snap in the depression between the adjacent reagent lattice, thereby thereby realizes realizing the location of enzyme mark bar reagent lattice.At this moment, the testing agency of hand held microplate reader will detect the reagent in the reagent lattice, so, thereby realizes that the hand held microplate reader is to the single-frame detection of enzyme mark bar under the hand push condition.
By above introduction, can find that it is detection mode single-frame that this hand held microplate reader adopts enzyme mark bar, this just makes the smaller volume of hand held microplate reader, thereby it is easy to carry, be convenient to testing crew and take it to on-the-spot detection,, make this hand held microplate reader reliable in quality again because present feed mechanism does not need drive disk assembly, failure rate is low, simultaneously simple in structure make cheap.
More than describe the structure of hand held microplate reader described in the utility model in detail by 3 embodiment; certainly; those skilled in the art can carry out the improvement and the conversion of structure based on the spirit that the utility model disclosed after reading the utility model; but; should know; embodiment of the present utility model is not the restriction to the utility model protection domain, so long as improvement and conversion that those skilled in the art do based on the spirit that the utility model disclosed all should fall into protection domain of the present utility model.
