By using the crush injury animal experiment instrument for carrying out animal crush injury experiment, the pressure and time can be controlled accurately, the obtained medical experiment data is true and reliable, and the operation is simple, convenient and rapid.
Description
Technical field
The present invention relates to a kind of crush injury zoopery instrument, belong to the medical experiment apparatus field.
Background technology
Crush injury-crush syndrome (Crush syndrome, CS) be because abundant limbs or the trunk of muscle pushed for a long time by weight, the muscle of pressurized ishemic part is damaged, and taking place with acute renal failure after removing extruding is the comprehensive syndrome of main clinical manifestation.Crush injury, the crush syndrome that causes owing to geological disaster, traffic wound, industrial and mining establishment's accident etc. is continuous ascendant trend at present.
Carry out the crush injury test with laboratory animal, obtain the relevant medical test data under certain pressure, time situation, significant for diagnosis, the treatment of human crush injury, crush syndrome.
At present, carrying out the method that crush injury experiment adopts mainly contains: the skeletal muscle extract is imported in the body (being applicable to larger animals such as pig) again, and meiofauna (as rabbit, rat etc.) is based on the limbs extruding; Fashion of extrusion has vapour-pressure type, as tourniquet compressing, the extruding of intermittent air bag; The weight extruding is arranged, and gripping objects such as self-control simple mould such as thin foaming vacuolar membrane, duroplasts piece, special plasticity plank add weight again and carry out the limbs compressing.
The shortcoming of vapour-pressure type is that the pressure inconvenience of tourniquet, intermittent air bag is measured, and precision is very low.
The shortcoming of weight extruding is, needs the counterweight of customization constant weight, and wants the special messenger to wait for, and pressurization, decompress(ion) all are manual operations.
Various extrusion experiment models are not quite similar, exert pressure weight (Kg) is also arranged, the difference of pressure (Pa, mmHg), pressing time has nothing in common with each other, randomness is very big, not standardization, controllable operator scheme.
Summary of the invention
At the problems referred to above, the invention provides a kind of crush injury experiment instrument, pressure and the time of extrusion process are accurately controlled, reduce error, improve accuracy and the credibility of experiment.
Technical scheme of the present invention is as follows:
A kind of crush injury zoopery instrument, comprise housing, pressing plate, pressing plate lifting driver, animal subject pallet and control device, described animal subject tray arrangement is at the end face of housing, described pressing plate lifting drive arrangement is in housing, its elevating lever vertically passes through the housing top board and connects pressing plate, this pressing plate is positioned at animal subject pallet top, corresponding animal subject; Described control device comprises pressure transducer and the time relay, and described pressure transducer is arranged in the housing, the bottom surface of corresponding animal subject pallet, for detection of with set experimental pressure; The described time relay is configured in the pressing plate lifting driver control circuit, is used for setting and the control extrusion time.
Described animal subject pallet has quick clamper, is used for the constraint animal subject.
Described pressing plate lifting driver is a kind of of oil cylinder, cylinder, electric screw.
Described control device is digital control device, and its pressure transducer is digital pressure transducer, is furnished with nixie display; Its time relay is digital time relay, also is furnished with nixie display.
This crush injury zoopery instrument is applicable to small test animals such as rat, rabbit.
Carry out animal crush injury experiment with above-mentioned crush injury zoopery instrument, accurately controlled pressure and time, the medical experiment data of gained are true and reliable, and easy and simple to handle, quick.
Description of drawings
Fig. 1 is the structural representation of this experiment instrument;
Fig. 2 is the control device circuit block diagram of this experiment instrument;
Fig. 3 is the panel layout of this experiment instrument.
The specific embodiment
Referring to Fig. 1: this crush injury zoopery instrument mainly is made up of housing 7, pressing plate 4, pressing plate lifting driver 6, animal subject pallet 2, control device 9, described animal subject pallet 2 is arranged in the end face of housing 7, described pressing plate lifting driver 6 is arranged in the housing 7, its elevating lever vertically passes through housing 7 top boards and connects pressing plate 4, this pressing plate 4 is positioned at the top of animal subject pallet 2, corresponding animal subject 3; Control device 9 has pressure transducer 8 and the time relay, and pressure transducer 8 is arranged in the housing 7, the bottom surface of corresponding animal subject pallet 2, for detection of with set experimental pressure; The described time relay is configured in the control circuit of pressing plate lifting driver 6, is used for setting and the control extrusion time.Animal subject pallet 2 has quick clamper 5, is used for the constraint animal subject.The pressing plate lifting driver 6 general electric screws that adopt in the occasion that hydraulic pressure or air compression station are arranged, also can adopt oil cylinder or cylinder.
Referring to Fig. 2: control device 9 is digital control device preferably, comprises digital pressure transducer 8, and this pressure transducer 8 is furnished with nixie display 10, and digital time relay 12 is furnished with nixie display 11, memorizer 13, processor 14.
Referring to Fig. 1, Fig. 3: housing 7 has guidance panel 1, and nixie display 10,11 is arranged on the guidance panel 1.
The operating process of this crush injury zoopery instrument:
This crush injury experiment instrument is by controlling extrusion time and extruding weight, man-machine dialog interface comes into plain view experimental implementation, the operator can set different experiment parameters according to the experiment needs, and the experiment of different extrusion times and extruding weight all can be finished at a machine.Comparing other does not need the frequent extruding counterweight of changing from molding jig, removes compressing after being responsible for arriving extrusion time without the special messenger yet.Not only the experiment accuracy can be improved, conventional efficient can also be improved.
