Background

With the rapid development of rehabilitation, rehabilitation is now one of four directions of medicine, and parallels clinical medicine, preventive medicine and health care medicine. The rehabilitation from the initial orthopedics and nerve rehabilitation to the current critical rehabilitation, cardiopulmonary rehabilitation, tumor rehabilitation and pain rehabilitation … … is all the same, but the development speed is different. Cardiopulmonary rehabilitation is soon rising, and respiratory rehabilitation is a branch of cardiopulmonary rehabilitation. Respiratory rehabilitation is mainly aimed at patients with chronic obstructive pulmonary diseases. Chronic obstruction of the lungs is caused by "prolonged exposure to poor air conditions and smoking causing lung damage. The main symptoms are chronic cough, expectoration and shortness of breath.

Respiratory rehabilitation therapy mainly comprises three major parts, namely exercise therapy, respiratory training and energy management. Exercise therapy is the increase in exercise tolerance and physical activity that is achieved by physical activity causing energy expenditure. The mode includes intermittent aerobic, intermittent resistance, continuous aerobic, continuous resistance, endurance training, etc. Continuous attention to patient symptoms (shortness of breath, dizziness and chest distress) is required during the activity, and if necessary, heartbeat, blood pressure and oxygen saturation before and after training are required, and an unexpected preparation scheme is also required. Exercise therapy is also at risk to the patient.

When respiratory rehabilitation training is carried out on a child patient, the existing rehabilitation means often have the following defects during training:

1. the patient who needs to breathe rehabilitation training often respiratory has received certain damage once, and is relatively fragile some, consequently when carrying out breathing rehabilitation training, needs to carry out certain cleanness to admitting air, prevents that patient's respiratory from receiving secondary infection.

2. At the in-process of breathing rehabilitation training, often need carry out supplementary thorax to the patient and press, however when artifical pressing the patient, often dynamics is difficult to the uniformity control, and medical personnel's working strength is also great simultaneously, presses repeatedly to lead to fatigue for a long time easily, then control effect and intensity better.

10. A method of using the breathing assistance apparatus for child rehabilitation according to any one of claims 1 to 9, characterized in that: the method comprises the following steps:

the method comprises the following steps: opening the magnetic hasp (48), turning up the pressing mechanism (41), enabling the patient to lie on the operating platform (1), covering the pressing mechanism (41) and closing the magnetic hasp (48), rotating the rotating wheel (27), adjusting the operating platform (1) to be proper in height, arranging the breathing mask (5) at the mouth and nose of the patient, and sliding the auxiliary pressing component (4) to the position of the chest of the patient;

step two: starting a motor (3302), wherein the motor (3302) drives a rotating rod (3303) to rotate, a piston plate (3204) is pulled through a movable connecting rod (3206) to blow air, air pressure drives a first air pipe (3103) to enter air, and the air is filtered by filtrate (3102), discharged by a second air pipe (3104) and enters the breathing mask (5) along an air outlet pipe (3202);

step three: the air pump (46) is started through the control panel (47), the air pump (46) works to repeatedly carry out air transmission and air suction on the rubber air bag (49), and the rubber air bag (49) is repeatedly expanded and contracted to continuously and intermittently press the chest of the patient.
