Description

Technical Field

[0001] The utility model relates to the technical field of calibration instruments, in particular to a calibration instrument for a pulmonary function instrument. Background Art

[0002] Pulmonary function testing is one of the necessary examinations for respiratory diseases. It can detect lung and airway lesions at an early stage, evaluate the condition and prognosis, identify the cause of dyspnea, diagnose the location of the lesion, evaluate lung function for surgical tolerance and patient monitoring. It is of great significance. Usually, pulmonary function instruments are used to test vital capacity, lung volume and other indicators. Clinically, in order to ensure the reliability of test results, daily maintenance of pulmonary function instruments is required, among which calibration and calibration are particularly necessary and must be performed every day. However, at present, when medical staff use calibration cylinders to operate and calibrate pulmonary function instruments, the calibration accuracy is low.

The front end of the calibration cylinder is used to connect the pulmonary function instrument, and a piston is provided in the calibration cylinder; the push-pull rod is connected to the piston, and the push-pull rod extends from the rear end of the calibration cylinder; the output end of the driver is connected to the push-pull rod, and the driver is used to drive the push-pull rod to drive the piston to move forward and backward. The driver drives the push-pull rod to move, and the push-pull rod drives the piston to move back and forth in the calibration cylinder, thereby pushing gas into the pulmonary function instrument for calibration. Driven by the driver, the piston moves smoothly, and the gas flow in the pulmonary function instrument is stable, which can improve the calibration accuracy.

[0004] In the prior art, adding components such as a calibration cylinder, a push-pull rod and a driver will effectively solve the problem of low calibration accuracy when medical staff use the calibration cylinder to calibrate the pulmonary function instrument.
