Background technology
Along with the development and clinical the deepening continuously that assessment is familiar with to pulmonary function of electronic computer technology, lung function has become one of clinical pulmonary disease three big diagnosis, so the application of spirometer also more and more widely.Adopt spirometer to forced vital capacity (FVC), vital capacity (VC), maximum minute ventilation (MVV), when tranquillization ventilation indexs such as (MV) is tested; Be subject to condition effect such as pick off, temperature, humidity; The test result fluctuation range is bigger, thereby makes spirometer when practical application, can have influence on the diagnostic result to patient's pulmonary function.In order to satisfy the quality control requirement that can satisfy spirometer; The index of spirometer is carried out daily calibration, calibrated the particularly necessity that seems; Yet the equipment of existing pick off blow gas to spirometer is not easy to control to the gas volume amount that blows to pick off, thereby is prone to the accuracy of influence test.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of can to the gas volume amount of the pick off that blows to spirometer control be used for spirometer calibration calibration the time release the device of gas.
The purpose of this utility model mainly realizes through following technical scheme: release the device of gas when being used for spirometer calibration calibration, the piston plate that comprises left cover that right ends is equipped with the cylindrical cylinder body of opening, blanket gas cylinder body opening and right cover plate, is arranged in the cylinder block and is tightly connected with the sidewall of cylinder block, be connected and pass the push-pull bar of right cover plate with piston plate; Be provided with the position-arresting disk that is connected on the push-pull bar between said piston plate and the right cover plate, said left cover and right cover plate are equipped with connects the inner passage of cylinder block.
Said push-pull bar is provided with more than one positioning hole, and said position-arresting disk passes position-arresting disk and is connected with push-pull bar through the fixed block that embeds in the locating hole.
Said locating hole is perforation or groove.
Said fixed block is pin key or screw.
Said position-arresting disk is metal gasket or rubber blanket.
Be arranged with sealing ring on the said piston plate.
Said cylinder block is metal cylinder, resin cartridge, plastic barrel or lucite tube.
The operation principle of this utility model: when this utility model is applied to spirometer; The passage of left cover is over against the pick off of spirometer; The control push-pull bar drives piston plate and does the reciprocating-piston motion, thereby the operation cylinder block obtains the content volume parameter thus to the gas of spirometer release normal volume amount on spirometer; Calculate the error of spirometer, then can calibrate the instrument that surpasses in the limit error scope.
This utility model compared with prior art has the following advantages and beneficial effect: (1) this utility model comprises cylinder block, push-pull bar, position-arresting disk and piston plate; This utility model is simple in structure, be convenient to realize; And cylinder block is pushed the gas volume amount of spirometer to and can be confirmed through regulating the link position of position-arresting disk on push-pull bar; This useful application is in when the pick off of spirometer is released gas; Can release the gas of normal volume amount to pick off, improve accuracy the spirometer test.
(2) push-pull bar of this utility model is provided with more than one positioning hole; Position-arresting disk embeds in the locating hole through the fixed block that passes position-arresting disk and is connected with push-pull bar; Syndeton is simple, be convenient to realize; The link position of position-arresting disk and push-pull bar is carried out easy to adjust, be convenient to the space between left cover and the piston plate is limited, thereby be convenient to the control that the volume to this utility model output gas carries out.
