At present, the reagent of automatic clinical chemistry analyzer, the consumption of sample all is a trace level, the application of sample of sample and reagent once can only carry out the difference application of sample of sample or reagent to a cuvette by sample injector, do how many Interventions Requested and carry out the application of sample operation of the sample reagent of how many times with regard to needing the contrast colors cup, this makes detection speed and work efficiency be subjected to very big restriction.
The utility model content
Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of automatic clinical chemistry analyzer multichannel syringe that can once add reagent to a plurality of cuvettes to be provided.
Technical scheme: in order to realize above purpose, a kind of multichannel syringe described in the utility model, a kind of multichannel syringe, each passage syringe comprises: input/output port, plunger cavity, basic point monitor, shielding portion, screw rod, stepper motor, plunger, copper nut, injector housing, backstay; Connecting the plunger cavity links to each other with stepper motor by injector housing; Input/output port is positioned at the top of plunger cavity, and plunger top is inserted in the plunger cavity and is tightly connected with this plunger cavity; The afterbody of plunger is connected with copper nut, and copper nut is spun on the screw rod, and screw rod links to each other with stepper motor, and shielding portion is located at the top of copper nut; The basic point monitor is positioned at the inside top of injector housing; Backstay is positioned at the inside bottom of injector housing.
In order to guarantee the stability of syringe front end, also be provided with the injector housing baffle plate between injector housing and progressive motor, reduced the influence of the vibrations of stepper motor motion generation to front end.
For enhanced leaktightness, be provided with O-ring seal between described plunger cavity and injector housing; Be provided with plunger bushing between injector housing and plunger.
The preferential 8 passage syringes that use of the utility model can be 8 cuvette filling reagent simultaneously, and the task of need make 8 filling reagent is originally once finished, and have improved the speed that detects.
Eight passage syringes are provided with 8 of input/output ports, 8 of plungers, 8 of O-ring seals, 8 of plunger bushings, 1 of copper nut, 1 of shielding portion, 1 of basic point monitor, 1 of backstay.
Beneficial effect: the utility model compared with prior art has the following advantages: because the machining precision of plunger cavity ensures easily in the utility model, thereby guaranteed the precision of filling reagent; Owing to use the utility model can save expensive import high-accuracy glass pipe, the use cost of having saved the client; Because the plunger seal circle is positioned between plunger cavity and plunger housing, does not follow plunger and carries out back and forth movement, is difficult for loss, need not frequent replacing, improve equipment life; Because the utility model can add reagent once for simultaneously a plurality of cuvettes, has accelerated the speed that detects, and has improved work efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the left view of the utility model embodiment.
Embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As Fig. 1, shown in the structural representation of a kind of embodiment of the present utility model, input/output port 1, plunger cavity 2, basic point monitor 4, injector housing 11, shielding portion 5, copper nut 10, plunger 8, backstay 13, screw rod 6, stepper motor 7; Injector housing 11 connects plunger cavity 2 and stepper motor 7; Input/output port 1 is positioned at the top of plunger cavity 2, and plunger 8 tops are inserted in the plunger cavity 2 and are tightly connected with this plunger cavity 2; Plunger tail is connected on the copper nut 10 mutually, and screw rod 6 is spun on the copper nut 10, and screw rod 6 links to each other with plunger 8 by copper nut, and screw rod 6 links to each other with stepper motor 7, and shielding portion 5 is connected the top of copper nut 10; Basic point monitor 4 is positioned at the inside top of injector housing 11; Backstay 13 is positioned at the inside bottom of injector housing 11; Injector housing 11 and progressive 7 in motor also are provided with injector housing baffle plate 12; 11 of plunger cavity 2 and injector housing are provided with rubber seal 3; 8 of injector housing 11 and plungers are provided with plunger bushing 9.
This example is 8 passage syringes, and being provided with input/output port 1 and being 8, plunger 8 and be 8, O-ring seal 3 and be 8, plunger bushing 9 and be 8, copper nut 10 and be 1, shielding portion 5 and be 1, basic point monitor 4 and be 1, backstay 13 is 1.
