Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing. The present invention consists of a gas container part consisting of an exhaust port 1, a cylinder 2 and an air inlet 3, an air pressure generating part consisting of a piston 4, a return spring 5, a cam 6 and a motor 7, and the pressure measurement and control part of the present invention consisting of a pressure protection assembly 12 , the pressure sensor 11 and the input part of the single-chip microcomputer 13, the air pressure output part of the present invention is composed of the output electromagnetic valve 9 and the output part of the single-chip microcomputer 13.

[0011] When the present invention is in the initial working state, the contact surface between the cam 6 and the piston 4 is the minimum outer diameter of the cam 6. Due to the common pushing action of the spring 5 on the cylinder 2 and the piston 4, the piston 4 enters the cylinder 2 at least, and the c...

Abstract

The invention discloses a piston-type single-pulse air generator, belongs to the field of medical apparatuses, and in particular relates to a core technology, which is related to swallowing function detection and noninvasive intraocular pressure detection, in clinical medicine. The air generator is composed of a gas container part, an air pressure generating part, a pressure measurement and control part and an air pressure output part. According to the invention, the core technology of a noninvasive diagnosis method is provided for swallowing function measurement and noninvasive intraocular pressure measurement in the clinical medicine; and through the method, an obtained single-pulse airflow is high in pressure accuracy, the measurement of a pressure value is compatible with a domestic measurement standard, a pulse time and a speed of generating a pulse airflow are conveniently adjustable, software and hardware structures are simple to design, cost is low, a working efficiency is high and a working stability for a long time is good.

Description

technical field [0001] The invention relates to a medical device, in particular to a core technology related to swallowing function detection and non-invasive intraocular pressure detection in clinical medicine. Background technique [0002] After radiotherapy for patients with nasopharyngeal carcinoma, 67% of patients had dysphagia, 17% of whom had severe dysphagia. Severe dysphagia manifested as choking on drinking water, malnutrition due to reduced food intake, and aspiration pneumonia due to misinhalation, which seriously affected patient's quality of life. The latest swallowing function testing equipment in the world transmits adjustable air pressure and long gas pulses to the inspection site through the inner channel of the fiberoptic laryngoscope. Specifically, the air pressure of 0 to 10 mmHg and the pulse air duration of 50 ms are used to stimulate the laryngeal epiglottic folds or the ventricular zone, causing the adduction of the ventricular zone to quantitativel...
