Device for helping pulse oscillation test

Abstract

The invention relates to a device for helping a pulse oscillation test. The device comprises a nose clamp, an elastic testing band and two face clamping pieces, the elastic testing band is composed ofa noise constraint band, two face constraint bands and connecting components, the two face constraint bands are connected to the two ends of the nose constrain band respectively, the connecting components are connected to the ends of the face constraint bands, two round pads used for clamping a nose are arranged at the front end of the nose clamp, the two face constraint bands are sleeved with the two face clamping pieces through sliding bushes respectively, two elastic through holes are formed in the nose constrain band, and the round pads at the front end of the nose clamp penetrate throughthe elastic through holes. In the natural state without external force, the diameter of the elastic through holes is smaller than that of the round pads at the front end of the nose clamp. The deviceis simple in structure, convenient to use and capable of solving the problems that in the prior art, when the pulse oscillation test is performed, the two sides of a face need to be supported by special staff, and a nose clamp is prone to falling, and is fixed firmly.

Description

technical field [0001] The invention relates to a device for auxiliary pulse oscillation test. Background technique [0002] The pulse shock test is to measure the airway resistance of the subject. The test steps are as follows: the subject takes a seat during the test, relaxes the whole body, holds the mouth of the instrument, the operator pinches his nose with a nose clip, and pays attention not to leak air. Tilt up to keep the airway open. The operator supports the cheeks on both sides of the subject with both hands to prevent the cheeks from vibrating with the oscillation signal and causing errors. Then the subject was asked to breathe calmly for 1 minute, and the test was completed. The computer automatically collects data, calculates, displays and prints out the measurement results. If the measured values ​​of R5 and R20 are greater than 115% of the expected value, the airway resistance is increased. [0003] The above test process has the following disadvantages: ...
