Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of portable pressure checkout equipment.
In the utility model embodiment, with reference to Fig. 1, Fig. 2 and Fig. 3, this portable pressure checkout equipment comprises and obtains for pressurized air the pressure supply module 10 that the gas of target pressure value is supplied to product to be measured, for monitoring the monitoring modular 20 of the real-time pressure value of this pneumatic supply and the display module 30 for the real-time pressure value that shows described pneumatic supply; Wherein, the exhaust end of described pressure supply module 10 is connected with described product to be measured, and the collection terminal of described monitoring modular 20 contacts with the gas in described pressure supply module, and the output terminal of described detecting/monitoring module 20 is connected with the input end of described display module 30.
Particularly, this portable pressure checkout equipment also comprises a square shell 80, by shell, pressure supply module 10, monitoring modular 20, display module 30 is integrated into a square, makes volume little, be easy to carry.This portable pressure checkout equipment also can arrange battery case 50, power key 60, operation push-button 70, with the switching of practical function and unlatching, in addition, display module 30 is preferably LCDs.
There is provided stable demarcation pneumatic supply to product to be measured by pressure supply module 10, product to be measured is generally pressure transducer, patient monitor etc.; Now, opening power key 60, monitoring modular 20 and display module 30 are started working, and the gas pressure value of being gone out by the monitoring modular 20 Real-Time Monitoring supply of self, is presented on display module 30; The gas provided of the pressure supply module 10 that product to be measured receives, through process, also by gas pressure value that the display screen display real-time reception at this product to be measured arrives; The gaseous tension provided due to pressure supply module 10 is consistent with the gaseous tension that product to be measured receives, thus by the force value that force value and the product to be measured of comparison display module 30 display show, just whether this product to be measured distinguishable has problems.If force value is consistent, then product no problem to be measured; If force value is inconsistent, then product existing problems to be measured, can correct according to the force value of this portable pressure checkout equipment display.
Detected without the need to extra source of the gas is auxiliary by this portable pressure checkout equipment, convenient and swift, cost is low.
Further, with reference to Fig. 4, described pressure supply module 10 comprise one end open housing 11, for cover the openend of described housing 11 end cap 12 and for compress described housing 11 and end cap 12 surround the compression set 14 of gas in cavity 13; Wherein, described compression set 14 comprises screw rod 141 and is fixedly connected on the piston 142 of described screw rod 141 one end, described end cap 12 center is provided with the threaded hole 121 suitable with described screw rod 141, advances described piston 142 to move back and forth in cavity 13 by the turn of described screw rod 141.
The cavity 13 that housing 11 and end cap 12 enclose is in tubular, and it is inner that piston 142 is positioned at cavity 13, by being connected to the turn of the screw rod 141 on piston 142, according to screw structure principle, promoting piston 142 and moving back and forth in cavity 13.By threaded hole 121 by screw rod 141 toward cavity 13 inner turn time, cavity 13 volume reduces, and by the air of compaction cavum 13 inside, makes inner air pressure become large; During by screw rod 141 toward cavity 13 outside turn, the volume of cavity 13 increases, and the air pressure of its inside diminishes, now, the collection terminal of monitoring modular 20 contacts with the air in cavity 13, can air pressure value in Real-time Collection cavity 13, and transfers to display module 30 and show.Because the turn of screw rod 141 can the accurately reciprocating displacement of control piston 142, thus can the pressure of accurate adjustment air; And when screw rod 141 stops turn, the pressure of the air in cavity 13 will not change, stable pneumatic supply can be provided to pressure supply module 10.
Further, described housing 11 is in tubular, and its closed end center is provided with through hole, and described through hole stretches out the interface 15 formed for being connected with product to be measured.
Because piston 142 is cylindric, housing 11 is arranged to tubular, with piston 142 mating shapes.Through hole is set at the closed end of housing 11, and stretches out and form the interface 15 that is connected with product to be measured, particularly, can by the size of this interface 15, with the suitable setting of size of general Medical gas-pipe (ISO594).During test, can easily this portable pressure checkout equipment be connected with medical product to be measured, thus stable air pressure is passed to product to be measured by this interface 15.
Further, described piston 142 and described cavity 13 interference fit.
Piston 142 and cavity 13 interference fit, in test process, can meet in cavity 13 is confined space, thus by the gaseous tension in the adjustment cavity 13 of the turn precision of screw rod 141.
Further, described compression set 14 also comprises O RunddichtringO 143, and described piston 142 is provided with annular groove 144, and described O RunddichtringO 143 makes described piston 142 seal described cavity 13 with described groove fit.
In order to strengthen the leakproofness in cavity 13, piston 142 arranges annular groove 144, and by O RunddichtringO 143 and groove fit, make cavity 13 reach better leakproofness, effectively can increase the precision that pneumatic supply regulates.
Further, with reference to Fig. 1, described monitoring modular 20 comprises pressure transducer 21 and processing module, the test side of described pressure transducer 21 is arranged on the inwall of described cavity 13, gather the force value of described cavity 13, and described force value is converted into corresponding voltage signal is passed to described processing module, after described voltage signal processes by described processing module, control described display module 30 and show corresponding force value.
Particularly, the force value of the gas in this cavity 13 changes, the resistance bridge of pressure transducer 21 inside is changed, thus the voltage generation respective change that pressure transducer 21 is exported, be passed to processing module by the pressure change change in voltage converted on pressure transducer 21 in cavity 13 and process.
Further, described pressure transducer 21 is the slope that makes described force value and the change linear transducer consistent with the slope that described voltage signal changes.
Precision due to pressure transducer 21 directly has influence on the display of follow-up display module 30, in order to make pressure conduction and process rear undistorted, this pressure transducer 21 is chosen as linear high-precision sensor, for example, as pressure change 2mmHg, on this pressure transducer 21, corresponding change in voltage is 2mV, thus change value of pressure can be reacted accurately on the changing value of voltage, thus follow-up processing module to this voltage signal process time, error will reduce, and can ensure the authenticity of Signal transmissions to greatest extent.
Further, described processing module also comprises for described voltage signal being carried out amplifying signal amplification module 22, being used for the voltage signal of described amplification to convert to the A/D modular converter 23 of corresponding digital signal, and described digital signal is carried out processing and export the MCU24 of corresponding pressure value to described display module 30; Wherein, the input end of described signal amplification module 22 is connected with the output terminal of described pressure transducer 21, output terminal is connected with the input end of described A/D modular converter 23, and the I/O mouth of described MCU24 is connected with the output terminal of described A/D modular converter 23, the input end of display module 30 respectively.
