The specific embodiment
Embodiment 1
As depicted in figs. 1 and 2, the self administration system of monkey For Drug Discrimination Test model comprises casing 1 at least, is placed in heating unit 2 in casing 1, administration unit, light source 3 and noise source 4, heating unit 2, light source 3 and noise source 4 respectively with the electric power generating composition loop, pullswitch is serially connected in the loop.The administration unit comprises to medicine-chest 6 and administration spoon 7, is connected for medicine-chest 6 with the administration spoon and connects by pipeline 10, is connected to valve 11 on pipeline, and valve 11 is electrically connected to control unit 9.There is an image unit to be electrically connected to display outside casing 1 in casing 1.Light source 3 is one group of redness or green indicating lamp.Can be also one group of redness and green indicating lamp.The pullswitch K1 that controls light source 3 is the rope of different colours, pulls the rope of different colours by animal, and one group of red led and one group of green indicating lamp reach visual condition to stimulate.When stimulating, the valve 11 on pipeline is opened, and enters in administration spoon 7 for the pill of medicine-chest 6 from pipeline, completes the selection self administration.
Embodiment 2
The pullswitch K2 in embodiment 2 control noise sources 4 as different from Example 1, noise source 4 work, noise source is modulating audio frequency circuit and an audio power output circuit, audio power output circuit is electrically connected to loudspeaker, modulating audio frequency circuit and audio power output circuit are serially connected in power circuit by pullswitch, and when stimulating, the valve 11 on pipeline is opened, enter in administration spoon 7 for the pill of medicine-chest 6 from pipeline, complete the selection self administration.
Embodiment 3
That different with embodiment 2 from embodiment 1 is the pullswitch K3 that embodiment 3 controls heating unit 2, heating unit 2 work, heating unit is heater strip or the heating lamp that is placed in the box perispore layer, heater strip or heating lamp and be electrically connected in series current limiting pipe in series circuit by switch and power supply.Pullswitch K3 pulls, heater strip or heating lamp work, and the temperature of casing 1 raises, and controller 13 is by detected temperatures, and when temperature arrived design temperature, controller 13 was controlled motors 12 and is rotated, and automatically opened chamber door 8 one gaps, regulated temperature.
Casing is that 750 millimeters of length, width are 900 millimeters, highly are 1800 millimeters.
As shown in Figure 2, control unit 9 comprises a valve 11, motor 12, controller 13, Acquisition Circuit and on-off circuit 15, Acquisition Circuit is made of three road stabilivolts and resistance series connection, in the work loop of heating unit 2, light source 3 and noise source 4, be used for to gather the duty of heating unit 2, light source 3 and noise source 4, be connected in series respectively K1, K2 and K3 in on-off circuit 15 in heating unit 2, light source 3 and noise source 4 work loops; Determine by K1, K2 and K3 whether heating unit 2, light source 3 and noise source 4 work loops work.Rectification circuit 14 exchanges 220V and carries out forming DC voltage after rectifying and wave-filtering, the work loop of heating unit 2 in parallel during direct current is pressed, light source 3 work loops and noise source 4 work loops.K1 connects, the dc source anode passes through light source 3, K switch 1 and first via sample circuit to negative terminal, K switch 1 closure, the stabilivolt of first via sample circuit (3V or 5V stabilivolt) work has 3V or 5V output, and output signal is input to an I/O mouth of controller 13, controller 13 receives the signal of telecommunication, by eliminating the switching noise signal, whether work with by-pass valve control 11, whether decision puts into food or medicine by pipeline 10 to administration spoon 7 by the medicine-chest 6 of giving of Fig. 1.Equally, K2 connects, the dc source anode passes through heating unit 2, K switch 2 and the No. the second sample circuit to negative terminal, K switch 2 closures, the stabilivolt of the No. the second sample circuit (3V or 5V stabilivolt) work, 3V or 5V output is arranged, output signal is input to the 2nd I/O mouth of controller 13, and controller 13 receives the signal of telecommunication, by eliminating the switching noise signal, whether work to control motor 12, open chamber door 8 regulating and controlling temperatures.Same again, K3 connects, the dc source anode passes through noise source 4, K switch 3 and Third Road sample circuit to negative terminal, K switch 3 closures, the stabilivolt of Third Road sample circuit (3V or 5V stabilivolt) work, 3V or 5V output is arranged, output signal is input to the 3rd I/O mouth of controller 13, and controller 13 receives the signal of telecommunication, by eliminating the switching noise signal, whether work with by-pass valve control 11, whether decision puts into medicine or food by pipeline 10 to administration spoon 7 by the medicine-chest 6 of giving of Fig. 1.
The present invention is according to the principle of trained reflex, and laboratory animal is mandatory, and to look for medicine capable, makes researcher set up the experimental tool of a whole set of effectively evaluating drug dependence begetting power.After reward stimulation and certain specific environment were contacted repeatedly, the Rhesus Macacus that participates in experiment just can obtain to award characteristic, namely can bring out in this specific environment the sort of non-conditioned behavior effect that the initial and non-condition award of animal links together.
