Description

A pulmonary function rehabilitation respirator for children

Technical Field

The invention relates to the technical field of lung function rehabilitation training devices, in particular to a children's lung function rehabilitation ventilator.

Background technique

The children's pulmonary function rehabilitation ventilator is a measuring instrument that can perform lung function tests and track lung health. It plays a very important role in pediatric lung function treatment. The existing lung function rehabilitation physiotherapy device mainly includes a main unit and an air pump connected by an airway. A disposable mouthpiece is installed at the air nozzle of the air pump to isolate the air nozzle from direct contact with the lips. The mouthpiece is removed after the blowing test is completed.

At present, the respiratory rehabilitation training devices on the market are mainly aimed at the middle-aged and elderly people. The product has a large gas capacity and is not suitable for the chest expansion range of children. In addition, children are emotionally unstable due to illness and are prone to anxiety, inferiority, and negative emotions. The respiratory training process is even more boring, and it is difficult for children to cooperate with medical staff for rehabilitation training. There is a lack of devices that combine game therapy with training factors to stimulate children's interest through games and help improve children's physical and psychological conditions. For this reason, we propose a children's lung function rehabilitation respirator.

Summary of the invention

In view of the deficiency of the children's lung function rehabilitation respirator in the prior art that is not interesting, the present invention provides a children's lung function rehabilitation respirator, which has the advantages of simple structure, easy use and interesting training effects produced by the combination of training and games.

To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a pediatric lung function rehabilitation respirator, comprising a nozzle and a shell, the back of the nozzle is fixedly connected with a bellows, the tail end of the bellows is detachably connected with a filter tube, the tail end of the filter tube is detachably connected with a connecting tube, the tail end of the connecting tube is fixedly connected with a shunt tube, the back of the shunt tube is provided with a first Tesla valve, the tail end of the first Tesla valve is fixedly connected with a first air cavity, the front part of the first air cavity is provided with an air outlet, the outside of the air outlet is fixedly connected with a sealed cavity, the back of the sealed cavity is fixedly connected with a second air cavity, the top of the second air cavity is fixedly connected with an air outlet pipe, the tail end of the air outlet pipe is fixedly connected with the connecting tube, and the tail end of the connecting tube is provided with a balloon.

Preferably, a baffle is fixedly connected to the interior of the first air cavity, a limiting tube is fixedly connected to the tail end of the first air cavity, air holes are provided on both sides of the limiting tube, a small ball is arranged inside the limiting tube, and the small ball can drive the air to vibrate by blowing, thereby driving the cilia on the inner wall deep in the child's airway to resonate, thereby loosening the sputum and other secretions stuck in the airway and detaching them from the airway surface.

Preferably, a rotating rod is provided inside the sealing cavity, the front end of the rotating rod is fixedly connected to the first knob, the outside of the rotating rod is fixedly connected to a fixer, the tail end of the rotating rod is fixedly connected to a connecting piece, the back of the connecting piece is fixedly connected to a sealing block, and four grooves distributed in a circular shape are provided outside the first knob. Rotating the first knob can make the rotating rod drive the connecting piece to rotate, so that the position of the sealing block changes, and then the size of the air outlet is adjusted so that the child can feel different pressures when exhaling.

Preferably, a second Tesla valve is provided on the back of the shunt pipe, the tail end of the second Tesla valve is fixedly connected to a pipeline, the top of the pipeline is fixedly connected to a detection tube, the tail end of the detection tube is fixedly connected to a flow meter, and the first Tesla valve and the second Tesla valve can realize one-way flow of airflow.

Preferably, a rotating shaft is also provided inside the pipe, a connecting plate is fixedly connected to the outside of the rotating shaft, a first magnet is fixedly connected to the inside of the connecting plate, a second magnet is provided outside the first magnet, a screw rod is fixedly connected to the back of the second magnet, a limiting ring is fixedly connected to the outside of the screw rod, and a second knob is fixedly connected to the tail end of the screw rod.

Preferably, armrests are fixedly connected to both sides of the shell.

Preferably, four sealing blocks of different specifications are provided.

Beneficial effects:

1. The children's lung function rehabilitation respirator exhales through the mouthpiece, and the gas is filtered through the filter tube to remove impurities such as moisture inside the gas, and then enters the shunt tube through the connecting tube. At this time, the second Tesla valve will block the airflow, and the airflow enters the first air cavity through the first Tesla valve, and enters the limit tube through the vent to blow up the ball, causing the ball to vibrate, and then reaches the sealed cavity through the air outlet, and reaches the balloon through the second air cavity through the air outlet pipe and the connecting tube. If the amount of exhaled gas is sufficient, the balloon can be blown up, so that children are interested in blowing the balloon up, which increases the autonomy of children's training.

2. The children's lung function rehabilitation respirator installs the nozzle and the filter tube through the threaded structure set inside the bellows and the filter tube, and then the child can inhale through the nozzle. During this process, the position of the screw rod can be adjusted to drive the second magnet away from or close to the first magnet. During inhalation, the airflow squeezes the connecting plate, and the second magnet attracts the first magnet, so that the child can feel the different inhalation pressures through the interaction between the magnets during the inhalation process. The airflow is calculated by the flow meter through the pipeline and displayed on the screen, so that the child can see the numbers getting smaller or larger, which stimulates the child's competitive psychology and increases the child's autonomy in training.
