Abstract
The utility model discloses a traumaless sphygmomanometer for small animals, which is composed of a pulse transducer, a pulse pressure sleeve, a rubber tube, a three-way tube, an inflation ball, a sphygmomanometer, a pressure amplifier an a micro electricity amplifier. The pulse transducer is utilized to amplify pulsatile signals of pulses of small animals and to reflect the signals to the micro electricity amplifier; thus, a pulse pulsatile curve is displayed. When the blood pressure measuring system is connected, the pressure value of the small animal can be obtained conveniently, quickly and accurately. In addition, the traumaless sphygmomanometer for small animals is also suitable for measurement of human body finger (toe) end volume change.
Description
This utility model relates to a kind of instrument that the toy blood pressure is measured, and is used to measure toy limbs, afterbody arteriotony value.Also can be used for observing the measuring instrument that human body refers to (toe) end volume-variation.
Carry out in the scientific experiments in biological, medical circle, adopt the frequent instrument that uses of blood pressure (as the arteriotony of rat) of non invasive method experiments of measuring toy to have three kinds: the one, with photo-electric rat survey meter of blood pressure; The 2nd, adopt afterbody volumetric method rat survey meter of blood pressure; The 3rd, handle CRS-III rat heart rate blood pressure instrument as calculated.When these instruments used, method was complicated, and required instrument and equipment costliness tests the speed slowly, and is very inaccurate to measured pressure value, influences the science of experimental data, and can not be used for the measurement that human body refers to (toe) end volume-variation.Therefore, how can easyly fast, accurately record the toy pressure value when toy is experimentized, be the problem that is worth solution when carrying out the toy experiment.
The purpose of this utility model is a kind of non-invasive measurement instrument that can directly quick and precisely record the toy pressure value of design.By selecting for use transductive material and being connected of battery lead plate, lead to make sphygmograph transducer, the small pulse of toy beaten the signal augmenting response to existing little electric amplifier, the display pulse curve of beating by connecting the sphygomanometer systematic survey, obtains toy pressure value accurately again.
The purpose of this utility model is achieved in that lays two electrode plate in box body, between two battery lead plates piezoceramics crystal is installed, and it is external that two battery lead plates are connected outlet box with lead, joins with existing pressure transducer and little electric amplifier.The pressing plate capping of box body oral area, the surface is fixed with the frame cover plate with the topped pressing plate of latex film, forms to have highly sensitive sphygmograph transducer.Sphygmograph transducer is inserted in the pulse pressure cover, the pulse pressure cover that sphygmograph transducer will be housed with sebific duct is connected termination sphygomanometers of tee T, another termination inflatable ball with two tee Ts, lead is patched to pressure amplifier and little electric amplifier, promptly constitute toy blood pressure non-invasive measurement instrument.
Below in conjunction with accompanying drawing this utility model is described in detail.
Fig. 1 is this utility model complete layout.
Fig. 2 is this utility model pulse pressure transducer architecture sketch map.
Fig. 3 is this utility model user mode figure.
With reference to accompanying drawing 1,2, a kind of toy blood pressure non-invasive measurement instrument is made up of pulse pressure transducer (1), pulse pressure cover (2), sphygomanometers (3), sebific duct (4), inflatable ball (5), tee T (6), pressure transducer (7), lead (8), pressure amplifier (9), little electric amplifier (10), monitor (11).With reference to accompanying drawing 2, sphygmograph transducer is by box body (14), and electric pole plate (16), lower electrode plate (15), piezoceramics crystal (17), pressing plate (13), frame lid (12), lead (8) constitute.There is opening the upper end of box body (14), and distolateral have lead (8) to penetrate in the box body, and the box body intracavity is laid electric pole plate (16) and lower electrode plate (15), connects the monolayer piezoceramics crystal (17) that a kind of buzzer wafer cutting forms between two battery lead plates.The peristome of box body (14) has recess, and pressing plate (13) utilizes its aixs cylinder to hold in the mouth mutually with recess and closes, and with the topped pressing plate of latex film (13), adopts frame lid (12) fixing again, constitutes sphygmograph transducer.With reference to accompanying drawing 3, sphygmograph transducer (1) is inserted in the existing pulse pressure cover (2), adopt be linked in sequence tee T (6) → sphygomanometers (3) → inflatable ball (5) → pressure transducer (7) → pressure amplifier (9) → little electric amplifier (10) → monitor (11) of sebific duct (4) to constitute toy blood pressure non-invasive measurement instrument then.
During use, toy (as rat) afterbody is inserted in the pulse pressure cover, lead patches pressure amplifier and little electric amplifier, calms the anger by inflatable ball, and monitor can demonstrate the toy pulse curve of beating, and the while sphygomanometers indicate the toy pressure value.
Toy blood pressure non-invasive measurement instrument, can make things convenient for, record accurately, fast the blood pressure of toy, to the toy not damaged, the device simple practicality, but also can be used in the measurement that human body refers to (toe) end volume-variation, go out human heart output index in prediction on such basis, grasp human body cardiac function situation.
