Abstract

The utility model relates to an electrically driving and stimulating automatic counting mouse maze, comprising a shell, a mouse door, a bait container, an electrode, a relay, a triode and a counter. The electrically driving and stimulating automatic counting mouse maze is characterized in that the shell is provided with a baffle provided with the mouse door, and the base plate of the shell is respectively provided with a driving electrode and a trigger electrode. The electrode is connected with the counter through the relay and a delay circuit composed of the triode, a resistor and capacitance. One path which mice a mouse can pass through freely can be designed to be no electric stimulation in a plurality of paths of the maze arbitrarily. According to automatically testing and recording the failure time of passing through the maze after the test mouse is drugged, the drug effect and the performance index can be judged. The utility model has the advantages of simple structure, convenient use and reliable performance.

Description

Electricity drives, electrical stimulation is counted the mouse labyrinth automatically

The utility model relates to the electronic timer technical field, particularly a kind ofly is used for that zooperal electricity drives, electrical stimulation is counted the mouse labyrinth automatically.

When measuring the performance index of a certain medicine, often to verify its performance by means of the experiment of animal, present, the domestic experimental provision that is used to detect mouse space learning memory capability exists and costs an arm and a leg, and the shortcoming of the variable poor performance of root a tree name actual needs.

The purpose of this utility model provides a kind of physiology of intelligence, memory and the conditioned reflex of animal used as test, instrument of pharmacology of being used for, and it is to drive experimental mouse by electrical stimulation to count the mouse labyrinth automatically by electricity driving, the electrical stimulation of the labyrinth and the automatic record frequency of failure.

The purpose of this utility model is to realize like this, it comprises housing, the mouse door, bait container, electrode, relay, the triode sum counter, it is characterized in that in housing, being provided with the dividing plate of band mouse door, housing base plate be respectively arranged with drive electrode and trigger electrode, this electrode is connected with counter with the delay circuit that is made of triode, resistance, electric capacity by relay.

The utility model designs physical signs memory states such as multichannel maze learning, conditioned reflex in experimental mouse, can be set with one the tunnel in the multichannel labyrinth arbitrarily is no electro photoluminescence, experimental mouse can freely be passed through, the number of times of failing by the labyrinth after the experimental mouse medication of the automatic experimental record of root a tree name, decidable drug effect and performance index, also have simple in structure, easy to use, the advantage of dependable performance.

Below in conjunction with accompanying drawing the utility model is further described,

Fig. 1 is that electricity drives, electrical stimulation is counted the structural representation in mouse labyrinth automatically,

Fig. 2 is the synoptic diagram that drive electrode is provided with in housing

Fig. 3 is the synoptic diagram that trigger electrode is provided with in housing

Fig. 4 is the control electrical schematic diagram of Fig. 1,

Fig. 5 is the control counter circuit diagram,

As Fig. 1--shown in 5, this electricity drives, electro photoluminescence is counted the mouse labyrinth automatically and comprised housing 1, mouse door 2, bait container 3, electrode 4--5, relay J a, Jb, Jc, triode 3DG6B sum counter 6 is provided with the dividing plate 7 of being with mouse door 2 in housing 1, be respectively arranged with drive electrode 4 and trigger electrode 5 on the base plate of housing 1, this electrode 4--5 is by relay J c, Jb with by relay J a, and the delay circuit that triode 3DG6B, resistance R 1--R3, Rw, capacitor C 1 constitute is connected with counter 6; The principle of work of this experiment is to be provided with three to irritate district 8, a place of safety 9 and an isolated area 10, article 9, passage, but port number also root a tree name actual needs increases, subtracts, have one the tunnel to be no electrical stimulation in the multichannel labyrinth, rest channels is equipped with electro photoluminescence, and that it irritates intensity is adjustable continuously, three drive electrodes 4 adopt regularly and stimulate simultaneously, order about experimental mouse and actively seek place of safety 9 and bait food by the labyrinth; Its electric control principle is a single tube attracting electric relay, and relay J c is in "on" position, and its switching is by the K switch 1--K9 control of series connection, and when experimental mouse was bumped out any switch of K1--K9, relay J c outage, normally opened contact Jc1 disconnected; Normally closed contact Jc2 closure, the timing circuit of counter 6 is connected and is begun counting, because the Jc1 disconnection, because of the terminal voltage of C1 can not be suddenlyd change, triode 3DG6B still keeps cut-off state, but C1 is recharged and charging voltage rises by index law, makes the base potential of triode 3DG6B and then rise to conducting, and relay J a, Jb start working, Ja1 is by adhesive, light emitting diode D is luminous, disconnect with contact Jb1 often, at this moment between inside counting device 6 countings once.
