The first four-way gas-tpe fitting 16 is communicated with two inflator pumps 11, the first electromagnetic valve 14, the second four-way gas-tpe fitting 30 respectively by gas circuit connecting pipe 17; The second four-way gas-tpe fitting 30 is communicated with pressure transducer 29, the second electromagnetic valve 28, the first four-way gas-tpe fitting 16, three connections for breather pipe 32 respectively by gas circuit connecting pipe 17; Three connections for breather pipe 32 are communicated with the first air accumulator 12, the second air accumulator 13, the second four-way gas-tpe fitting 30 respectively by trachea; The first electromagnetic valve 14 is also communicated with cuff 33 by gas circuit connecting pipe 17.
In the time pressing preparation key 20, circuit board 15 bases are pressed the instruction of sending while preparing key 20, controlling two inflator pumps 11 starts, the gas-pressurized that two inflator pumps 11 produce enters first, second air accumulator through the first four-way gas-tpe fitting 16, the second four-way gas-tpe fitting 30 and three connections for breather pipe 32, thereby gives first, second air accumulator inflation.Because pressure transducer 29 is all communicated with first, second air accumulator, therefore the gas pressure in first, second air accumulator can be detected, pressure transducer 29 is transferred to circuit board 15 by the pressure information detecting in real time, circuit board 15 judges whether the pressure information that pressure transducer 29 transmits reaches the designed operating pressure value of this patent, while reaching 500mmHg, control described two inflator pumps 11 and quit work.
After preparation finishes, the required force value of cuff can FMD detection be set by pressure adjusting key 21 time.After setting, can press initiating key 22, now circuit board 15 is opened with the interface that the first four-way gas-tpe fitting 16 is communicated with controlling the first electromagnetic valve 14, open the interface that the first electromagnetic valve 14 is communicated with cuff 33 simultaneously, make the gas in first, second air accumulator flow into cuff 33, make cuff 33 moment inflation; Meanwhile, pressure transducer 29 detects the gas pressure in cuff 33 in real time, in the time that the gas pressure in cuff 33 reaches the FMD detected pressures value of setting, circuit board 15 controls the first electromagnetic valve 14 and cuts out with the interface that the first four-way gas-tpe fitting 16 is communicated with, and makes cuff 33 keep this preset pressure value; Meanwhile, circuit board 15 starts timing, and on LED display 24, shows the time that keeps pressure, thereby can inform how long user pressure has kept.
When checking that timing reaches the default time, can press stop key 23, now, circuit board 15 is controlled the gas outlet of the first electromagnetic valve 14 and is opened, thereby the gas in cuff 33 is flowed out by the gas outlet of the first electromagnetic valve 14, thereby realize moment venting, decompression is made zero.
Concrete, the FMD pressurization instrument in this utility model is noinvasive Noninvasive pressue device, can coordinate colorful Doppler ultrasound diagnostic apparatus to complete FMD and detect necessary upper limb blood vessel pressure process.Illustrate specific works principle and the work process of the instrument of FMD pressurization below:
Outlet 26 is connected with power supply by power line, and then power supply converts the unidirectional current of 10V-12V to through manostat 25, with thinking that circuit board 15 provides power supply; Press on and off switch 27, the circuit board 15 startup work that starts to switch on; Press and prepare key 20, inflator pump 11 is started working, producing gas-pressurized is that the first air accumulator 12 and the second air accumulator 13 pressurize simultaneously, this gas-pressurized sends the first air accumulator 12 and the second air accumulator 13 to through gas circuit connecting pipe, after the 500mmHg operating pressure value that arrives design until two air accumulator air pressure inside, inflator pump 11 quits work.Then pressing force adjusting key 21, the force value of the required cuff 33 of cuff when setting FMD and detecting, after ultrasonic examination preparation is ready, (bundle cuff 33, ultrasonographic probe is accurately placed on blood vessel and detects position, detect front basic blood vessels caliber measurement etc.), press initiating key 22, the gas-pressurized of the first air accumulator 12 second air accumulators 13 is through gas circuit connecting pipe 17(connecting silicone pipe) moment outputs to cuff 33, start limbs pressurization, blocking blood flow, pressure receptor regulation and control pressurization overall process.In persistent pressure after 5 minutes, by stop key 23, cuff 33 internal pressure abrupt releases, decompression is made zero.Now, LED display 24 continues to show timing, so that the needs of the timing such as the variation of brachial artery flow speed, blood flow and the blood vessel radial line after observation instant decompression, until device powers down.The FMD pressurization instrument that uses this utility model to provide, can realize and carry out automatically, fast limbs pressurization, greatly facilitate FMD inspection, and the air pressure moment that can make 33 li of cufves reaches and checks default maximum pressure value, when decompression, also can make the air pressure moment of 33 li of cufves make zero, therefore it is accurate to make FMD detect overall process, measurement data is stable and reproducible.In addition, on FMD pressurization instrument, be also provided with LED display 24, in the process of pressurizeing for cuff 33, LED display 24 can time synchronisation, with minute, second numeration, to show pressurization or the state and the numerical value that reduce pressure; In the time arriving Preset Time, press stop key 23, pressure process finishes, and LED display 24 continues to show timing, to complete the follow-up timing needs of FMD detection all processes, until device powers down.
