Abstract
The utility model discloses a mouse cough recording device. The mouse cough recording device comprises a size description box which is a closed cavity, the size description box is connected with a pressure transducer, the pressure transducer is electrically connected with an amplifier, and the amplifier is electrically connected with a processor. The mouse cough recording device is easy and convenient to operate and easy to implement, and objective and accurate experiment data can be obtained through the device.
Description
Technical field
This utility model relates to animal experiment device capable, relates in particular to a kind of mouse cough recording equipment.
Background technology
Cough laboratory method and experiment is done relatively simple because mice ammonia draws, and experimental cost is lower, in the antitussive of being everlasting effect experiment, is used widely as prescreening method.For the cough of mice, most literature is all to observe mouse web portion to shrink at present, simultaneously with gapemouthed action as judgment criteria, but in actual mechanical process, mouse cough moves sometimes and is not true to type, and because mice does not stop mobile in container, be not easy to observe, therefore, cause data to be difficult to accurate recording, and fluctuation is larger.Also there is minority document to mention the sound with stethoscope auxiliary record mouse cough, can obtain objective, experimental data accurately, still, experiment needs very quiet external condition, meanwhile, the mental status, proficiency level to observer have relatively high expectations, and are unfavorable for extensive use.
Utility model content
This utility model aims to provide a kind of mouse cough recording equipment, easy and simple to handle, easily go, and can obtain objective, experimental data accurately.
For achieving the above object, this utility model is realized by the following technical solutions:
The disclosed mouse cough recording equipment of this utility model, comprises plethysmography box, and described plethysmography box is a closed cavity, plethysmography box Bonding pressure transducer, and described pressure transducer is electrically connected amplifier, the electrical junction of described amplifier reason device.
Preferably, described plethysmography box is the wide mouthed bottle with rubber stopper, on described rubber stopper, has through hole, and described pressure transducer connects this through hole by pipeline.
Preferably, the volume of described plethysmography box is 200 to 300 milliliters.
Preferably, the internal diameter of the pipeline between described Bonding pressure transducer and through hole is 2.9mm to 3.9mm, and length is 50 to 100mm.
This utility model is easy and simple to handle, can accurate recording mouse cough number of times, and environment and observer require lower to external world compared with traditional method; The accuracy that has improved record, alleviates working strength.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is further elaborated.
As shown in Figure 1, it is the wide mouthed bottle of 200 to 300 milliliters that plethysmography box 1 adopts volume, bottleneck seals with rubber stopper 11, on rubber stopper 11 offer a through hole with bottle in be communicated with, pressure transducer 2 connects this through hole by pipeline, and the internal diameter of this pipeline is 2.9mm to 3.9mm, and length is 50 to 100mm, pressure transducer 2 is electrically connected with amplifier 3, and amplifier 3 is electrically connected with processor 4; As preferably, TSD160A type pressure transducer, DA100C type universal amplifier, MP150 type System of organism signal that pressure transducer 2, amplifier 3, processor 4 select respectively BIOPAC company of the U.S. to produce.
Volume is that 200 to 300 ml volumes are traced case 1, and volume is moderate, is applicable to placing drawing by ammonia spraying the mice coughing, and can meet the certainty of measurement of pressure transducer 2, can guarantee again the respiratory capacity of mice in the experimental period about 3 minutes; Wide mouthed bottle and rubber stopper 11 selections are easy, with low cost.
Operation principle of the present utility model is: can be with the variation of instant airflow when mouse cough in plethysmography box 1, this variation can bring instantaneous pressure to change in an airtight space, by pressure transducer 2, the gas pressure in plethysmography box 1 is converted to the signal of telecommunication, input processor 4 after amplifier 3 amplifies again, the above-mentioned instantaneous pressure change frequency that processor 4 is recorded within experimental period, is the number of times of mouse cough.
Certainly; this utility model also can have other various embodiments; in the situation that not deviating from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to this utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of this utility model.
