Electromagnetic power expectoration machine with exhaust protection function

Abstract

The invention discloses an electromagnetic power sputum excretion machine with an exhaust protection function. The electromagnetic power sputum excretion machine comprises a cough inductor, a frequency input end, an air pressure input end, an electric control switch, a timing input end, a pressure waistcoat, an air vibrating machine and a fan. In addition, the electromagnetic power sputum excretion machine comprises a connecting pressure sensor, a relay switch, a solenoid valve and an exhaust fan. A timer, the exhaust fan, the solenoid valve and the relay switch are connected to monitor timing time, and when the timing time reaches first set value time, an alarm instruction is sent out; when the timing time reaches second set value time, a main control unit sends out the instruction of cutting off an electromagnet power source, the instruction of opening the solenoid valve to enable the exterior to be communicated with the interior of a pipeline and the instruction of turning on the exhaust fan. The electromagnetic power sputum excretion machine is easy to use, low in cost and suitable for being widely popularized in the utilization range of the excretion machine.

Description

technical field [0001] The invention relates to an electromagnetic power expectoration machine with exhaust protection function. Background technique [0002] Chest physical therapy has a long history of clinical application and is very effective. It is one of the standard medical methods in various countries to improve the mucus clearance function of the respiratory tract. The types of chest physiotherapy include: manual tapping on the back to expel sputum, and external vibration machine to expel sputum, all of which have many problems. [0003] In recent years, foreign countries are also developing and improving vest-type air pulse expectoration machines. The air pressure pulse machine repeatedly inflates and deflates the two airbags fixed on the front of the vest. Each pressurization will force the airflow to quickly pass through the lung lobes, push the secretion accumulation off the lung wall, and move to the mouth; Or negative pressure suction can be discharged. Its...

AI Technical Summary

Problems solved by technology

New problem: the fixed two-point anterior chest wall pulse cannot beat the side and back of the chest, and the expectoration effect is not good for some patients; after the treatment parameters are set, the treatment procedure is completely carried out according to the standard, and the treatment is not interrupted even if the patient's cough has been induced , may produce prolonged continuous coughing, leading to the danger of exhaustion and hyperventilation

[0018] The above scheme has solved the problems in the past well, but the air composed of the frequency voltage conversion circuit 15, the pulse regulator 16, the air pressure pulse regulator 17, the air pressure detection circuit 18, the power amplifier 19, the motor 20 and the air pressure compensator 21 The control of the oscillator 9 is relatively complicated. In addition, the air pressure compensation machine 21 is also completed by the motor. The response of the whole system is relatively slow, and it consumes more electricity.

At the same time, because the pressure in the vest exists for a long time, it will squeeze the patient's chest for a long time, which will easily cause the patient's soft tissue contusion.
