Negative pressure pulsation therapeutic instrument

Abstract

The invention discloses a negative pressure pulsation therapeutic instrument, comprising an air exchanging chamber, an airbag and a water accumulation bottle, wherein the air inlet of the water accumulation bottle is connected with a nostril end through a rubber pipe, and the air outlet of the water accumulation bottle is connected with an air inlet pipe of the air exchanging chamber through a rubber pipe. The therapeutic instrument is characterized by also comprising a rotor, a stator, a coil and a magnetic shoe; the airbag is a cylinder with outer wall being the shape of corrugation and is used for generating negative pressure pulsating air flow; and the air exchanging chamber and the airbag are communicated from front to back and meshed together at edges to form a closed air flow room; the rotor is connected with the airbag, and drags the airbag to reciprocate along the axis direction, so that the airbag is stretched or shortened. The device has the characteristics of large air suction volume, high efficiency, low noise, large negative pressure and the like, and is used for treating respiratory diseases of acute and chronic bronchitis, bronchial asthma, bronchial pneumonia, rhinitis, pneumonoconiosis and the like.

Description

technical field [0001] The invention relates to a device for treating respiratory diseases by physical methods, in particular to a device with a catheter and negative pressure suction for treating acute and chronic bronchitis, bronchial asthma, bronchial pneumonia, rhinitis, pneumoconiosis and other respiratory diseases of medical devices. Background technique [0002] Negative pressure pulsating lung clearing instrument uses negative pressure pulsating oscillating airflow to help patients exhale more residual air while breathing spontaneously, thereby increasing alveolar ventilation and helping to clear the airway, which is beneficial Eliminate inflammation; at the same time increase blood flow, increase blood oxygen content, eliminate symptoms such as coughing, wheezing, and suffocation, improve human respiratory power, ensure exhaust and phlegm, clear the airway, and enable patients to obtain easy and smooth effective breathing.

AI Technical Summary

Problems solved by technology

Both of these devices use compression cups, which use the interaction of electromagnets and permanent magnets to extract air. The main shortcomings are: the compression deformation of the cups is small, the extraction efficiency is low, and the controllable air flow is small. The range of negative pressure changes is small; because the electromagnet and permanent magnet have the working characteristics of instant attraction and slow release, the leather cup returns to its original position by its own elastic deformation. Cannot fully return to the original position, therefore, the negative pressure generated is small

The device uses a negative pressure pump and a solenoid valve to generate negative pressure pulsating airflow, and the negative pressure pump generates negative pressure airflow; the solenoid valve controls the on-off of the armature, completes the entry and discharge of the airflow, and forms a pulsating airflow; the negative pressure airflow is generated by the negative pressure pump , which makes the structure of the whole device complex and bulky, and the pull-in and disconnection of the solenoid valve and the armature bring a lot of noise
