First, three-ball breathing trainer.

This kind of breathing trainer usually consists of three transparent balls of different capacities. By inhaling, the balls rise, which intuitively shows the strength and capacity of inhalation. COVID-19 recovered patients can adjust the inhalation force according to their own recovery situation and gradually enhance the strength of respiratory muscles and lung function. It is easy to operate and convenient for patients to use at home by themselves.

Second, diaphragm pacemaker.

For the possible weakening of diaphragm function during the COVID-19 recovery process, the diaphragm pacemaker can play a certain auxiliary role. It prompts the diaphragm to contract and relax regularly by sending out electrical stimulation signals, thereby improving respiratory function. It is especially suitable for those patients with more obvious respiratory muscle weakness.

Third, resistance respirator.

The resistance respirator can provide different degrees of resistance. Patients need to overcome these resistances during inhalation and exhalation to achieve the purpose of exercising respiratory muscles. COVID-19 recovered patients can start from low resistance and gradually increase the resistance level to adapt to their own rehabilitation process.

Fourth, intelligent breathing trainer.

With the development of technology, intelligent breathing trainers are gradually being applied in the field of rehabilitation. This kind of trainer is usually equipped with sensors and a display screen, which can monitor the patient’s breathing parameters in real time, such as breathing frequency, depth, capacity, etc., and provide personalized training plans. At the same time, it can also be connected to a mobile phone application to facilitate patients to record and track their training progress.
