Description

The clear-headed simple and easy head brake unit of animal

Technical field

This utility model belongs to behavior electrophysiologic study instrument and equipment technical field, is specifically related to a kind of clear-headed animal head brake unit that is used with brain solid positioner.

Background technology

In neuroscience and psychological study field, often need carry out behavior electrophysiologic study (promptly in the body experiment), wherein very important a kind of research is that the record of brain cell electrical activity and Animal Behavior Science observation are carried out synchronously, this just requires animal should regain consciousness (being convenient to the consummatory behavior task), again the braking (being convenient to write down the cell electrical activity) that its head can be highly stable; Can and this braking be very high for the requirement of stability and persistent period, realize that therefore the head steady braking under the animal waking state determines the experiment key of success often.

Also do not carry out the arresting Perfected process of head at clear-headed animal specially at present.Past method commonly used is to use the activity of muscle relaxant paralysis animal, additional gas cannula and artificial respiration carry out so-called " clear-headed braking " to animal, though this can realize the stable braking of animal waking state, but it is big to animal injury, and because of the influence of tracheotomy and intubate makes animal be difficult to raise for a long time and is used for chronic and dynamic experiment is observed, can only be used for acute experiment, reduce the animal use rate.Need the ear bar of brain solid positioner is tightly withstood the external auditory meatus of animal in addition in use, this braking method not only causes animal pain, and has disturbed the naturalness of animal, and the audition correlational study can't be carried out.

Summary of the invention

The purpose of this utility model provides the simple and easy head brake unit of a kind of clear-headed animal, and it is simple in structure, easy to use, insensitivity is high.

The simple and easy head brake unit of clear-headed animal described in the utility model comprises tubular scaffold, it is characterized in that:

Described tubular scaffold is arranged symmetric screws by two and is installed in two brake pipes of arranging between the symmetric screw and forms;

Described brake pipe two ends cooperate with a end of two symmetrical ear bars on two curb girders of brain solid positioner respectively, and the symmetric screw of described two rows cooperates with the position that is braked of animal.

The utlity model has manufacture simple, cost is low, easy to use, the stability maintenance height, and can select brake pipe parameter, the quantity of screw and the distance between every row's screw according to the size of animal, be applicable to the head braking under the clear-headed condition of animals such as rabbit, rat, Cavia porcellus, mice, be specially adapted to the chronic experiment and the audition Related Experimental Study of brain research.This utility model has been simplified the arresting difficulty of clear-headed animal head, has improved work efficiency, has promoted carrying out of association area research work.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation of this utility model when user mode.

Among the figure: 1. brain solid positioner curb girder; 2. ear bar; 3. dentistry cement; 4. skull surface; The mouth of 5 animals; 6. mouth holder; 7. brake pipe; 8. screw; 9. tubular scaffold.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The simple and easy head brake unit of clear-headed animal as shown in Figure 1 and Figure 2, comprise tubular scaffold 9, described tubular scaffold 9 is arranged (totally four) symmetric screws 8 by two and is installed in two brake pipes of arranging between (totally four) symmetric screws 87 and forms, and can be connected and fixed by dentistry cement 3 between screw 8 and the brake pipe 7.Brake pipe 7 two ends cooperate with a end of two symmetrical ear bars 2 on two curb girders 1 of brain solid positioner respectively, and the symmetric screw 8 of two rows is that skull surface cooperates with the position 4 that is braked of animal.

More permanent for screw is used, and be difficult for getting rusty, two row's (totally four) symmetric screws 8 are the CARBURIZING FURNACE FOR STAINLESS FASTENER nail; In order to make brake pipe 7 hardness big, brake pipe 7 adopts the PU pipe; In order to be the moment that increases support, can be according to the suitable distance that increases between every row's screw of animal head size; In order to make insensitivity better, on the mouth 5 of animal, accompany the mouth holder 6 of brain solid positioner.

Making of the present utility model and use are as follows:

The head size different according to different animals, (avoiding writing down the shadow-mark district of brain district on the head surface) bores two rows totally four symmetric apertures as far as possible on the skull that exposes; Respectively with four disinfectant length be that 10.0 mm, diameter are that the CARBURIZING FURNACE FOR STAINLESS FASTENER nail 8 of 1.0 mm screws in four apertures; With one disinfectant brake pipe 7 be fixedly connected between two row's CARBURIZING FURNACE FOR STAINLESS FASTENER nails 8 by dentistry cement 3, the length of this brake pipe 7 is 12.0-15.0 mm, internal diameter is 4.0-6.0 mm, external diameter is 6.0-8.0 mm; Dentistry cement 3 is used to strengthen and the fixedly connection between CARBURIZING FURNACE FOR STAINLESS FASTENER nail 8, brake pipe 7 and the skull surface 4, for future use.

During use, the animal health is placed in the capsule, to reduce to shake off power, the tapering point of two symmetrical ear bars 2 of two curb girders 1 of brain solid positioner is inserted brake pipe 7 two ends withstands brake pipe 7, and clamp animal mouth 5 with the mouth holder 6 of brain solid positioner, reach the highly stable braking of head that realizes under the loose condition of clear-headed the no flesh of animal.
