Fixing device used for assisting impulse oseillometry

Abstract

The invention discloses a fixing device used for assisting impulse oseillometry, and relates to the field of medical assistant equipment for pulmonary treatment and detection. The fixing device used for assisting impulse oseillometry comprises a collar support device, a test band device and a transmission mechanism. According to the fixing device used for assisting impulse oseillometry, through the structures of ear holes, a limiting rope, a taper sleeve, a limiting clamping head and the like, clamping effects and the stability of cheek clamping boards are enhanced, the fixing device used forassisting impulse oseillometry can be suitable for patients at different ages, through the collar support device in cooperation with the structures of pull ropes, sliding rods, sliding sleeves, tension springs and the like, the positions of the cheek clamping boards can be simply and conveniently adjusted through pulling, the cheek clamping boards are made of a silica gel material, and can be attached to the cheeks of the patients well due to shapes with flat peripheries and convex centers, the situation that the cheek clamping boards generate vibration when subjected to impulse oseillometry is prevented, an attachment effect is better, and the fixing device used for assisting impulse oseillometry is more comfortable. The problems that existing fixing devices used for assisting impulse oseillometry do not have firm clamping effects on the cheeks of human bodies, is not comfortable enough to use, and cannot be conveniently suitable for patients at different ages are solved.

Description

technical field [0001] The invention relates to the field of medical pulmonary treatment and detection auxiliary equipment, in particular to a fixing device for auxiliary pulse oscillation. Background technique [0002] The pulse-shock test is a method of determining a patient's respiratory impedance. An oscillator is used to generate an external pressure signal, the change of the flow rate of the respiratory system under this pressure is measured, and the technology of spectrum analysis is applied to the calm breathing wave to measure the respiratory impedance. Through the respiratory impedance, the airway obstruction can be understood, and at the same time, the obstructed part can be distinguished to understand the compliance. [0003] Existing medical institutions often use a spirometer to test patients. During the test, the patient takes a seat and covers the mouth of the output port of the spirometer. The operator pinches his nose with a nose clip and tilts his head sl...
