Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a pneumatic breathing training vest and a training method. Background Art

[0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of critical care and respiratory rehabilitation, in order to solve the difficulty of critically ill patients to be taken off the ventilator and the difficulty in breathing due to high spinal cord injury, a respiratory nerve muscle stimulator is currently used to stimulate the respiratory muscles, thereby improving the patient's breathing ability. Specifically, the electrodes are attached to the abdominal muscles and diaphragm respectively. The respiratory nerve muscle stimulator uses external electrodes to perform accurate functional electrical stimulation on the phrenic nerve and abdominal muscles. During inhalation, the diaphragm is electrically stimulated to work, the diaphragm contracts, the abdominal muscle is electrically stimulated to turn off, and the abdominal muscles relax, thereby increasing the expansion amplitude of the chest and significantly increasing the inhalation volume. During exhalation, the diaphragm is electrically stimulated to turn off, the diaphragm relaxes, the abdominal muscles are electrically stimulated to work, and the abdominal muscles contract, thereby increasing the contraction amplitude of the chest and significantly increasing the exhalation volume.

[0004] The above-mentioned respiratory nerve muscle stimulator can enhance the amplitude of chest expansion or contraction through electrical stimulation, and improve the strength and endurance of respiratory muscles. However, the respiratory nerve muscle stimulator is a passive training device. Only when the patient has a certain breathing ability to cause chest rise and fall, the electrode can be activated by chest rise and fall. For patients with high spinal cord injury, the respiratory muscles will be in a paralyzed state, and the respiratory muscles cannot exert force independently. Patients cannot actively cause chest movements, and respiratory paralysis cannot heal itself. Pulmonary function exercises need to be performed under the guidance of a doctor, such as pursed lip breathing, abdominal breathing, etc., to enhance the strength and endurance of respiratory muscles. The recovery of pulmonary function exercises under the guidance of a doctor requires long-term guidance and care from a doctor. Summary of the invention

[0005] The purpose of the present invention is to provide a pneumatic breathing training vest that can at least solve one of the above-mentioned technical problems.

[0006] To achieve the above-mentioned objectives, the present invention proposes a pneumatic breathing training vest, a pneumatic breathing training vest, comprising a vest body, the vest body being divided into a first air bag and a second air bag, the first air bags being staggeredly arranged in the upper part of the vest body, the second air bags being arranged in the lower part of the vest body, the first air bags being connected to a main air pump through a first air port, and the second air bags being connected to an auxiliary air pump through a second air port.

[0007] It is further configured that the first airbag is a square airbag.

[0008] It is further configured that the second airbag is a square airbag or a vertical strip airbag.

[0009] It is further configured that the strip-shaped airbags are arranged along the length direction of the body.

[0010] It is further configured that a first airbag and a second airbag are correspondingly arranged on the back of the vest body.

[0011] It is further configured that the first air port is connected to a main air pump via an air pipe.

[0012] It is further configured that the second air port is connected to an auxiliary air pump through an air pipe.

[0013] It is further configured that a collar is arranged on the top of the vest body, and cuffs are arranged on both sides of the vest body.

[0014] It is further configured that a Velcro is provided below the collar of the vest body and in the center of the vest, and an elastic bandage is provided at the connection between the vest body and the two sides of the back.

[0015] The present invention also provides a training method for a pneumatic breathing training vest, the training method comprising:

[0016] The first airbag corresponds to the chest cavity setting, and the second airbag corresponds to the abdominal cavity setting. First, the main air pump is turned on to provide air pressure for the first airbag, and the auxiliary air pump is turned off. At this time, the chest cavity is squeezed, the chest cavity muscles are compressed, and the chest cavity volume is reduced to complete exhalation. Then the main air pump is turned off, and the auxiliary air pump is turned on to provide air pressure for the second airbag. At this time, the abdominal cavity is squeezed, the abdominal cavity muscles are compressed, and the abdominal cavity volume is reduced to complete inhalation. The main air pump and the auxiliary air pump are inflated alternately. Patients can receive treatment at home, and can complete training to enhance respiratory muscle strength and endurance without the guidance of a doctor.

[0017] Beneficial effects of one or more of the above technical solutions:

[0018] The main and auxiliary air pumps squeeze the chest and abdominal cavities alternately to achieve changes in the abdominal and chest cavities, and use the airflow to change the volume of the airbag. The airbag then squeezes the volume of the chest or abdominal cavity to complete the exhalation and inhalation functions and simulate human abdominal breathing. Even if the patient is unable to breathe independently, the rebound force of air pressure in the chest cavity can be used to contract or expand the respiratory muscles to improve their strength and endurance.

[0022] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 An embodiment of the present application provides a pneumatic breathing training vest, a pneumatic breathing training vest, including a vest body 1, the vest body 1 is divided into a first air bag 2 and a second air bag 3, the first air bag 2 is staggeredly arranged in the upper part of the vest body 1, and the second air bag 3 is arranged in the lower part of the vest body 1, the first air bag 2 is connected to the main air pump 6 through the first air port 4, and the second air bag 3 is connected to the auxiliary air pump 7 through the second air port 5.

[0024] The first airbag 2 is a square airbag, which is staggered on the chest. Since the lungs occupy a large area in the chest, staggering the square airbags on the chest can ensure uniform distribution of gas pressure. At the same time, the airbags are connected at the staggered points, so that after one airbag is ventilated, other airbags can also be inflated. Since the expansion of the lungs is caused by the expansion of the alveoli, the staggered square airbags can squeeze the lung area in turn after they are inflated in turn, simulating the actual lung expansion situation. The circumference of the square airbags is set in the chest cavity, so that the first airbag 2 can completely wrap the chest cavity after being inflated.

[0025] The second airbag 3 is a square airbag which is a vertical strip airbag. The strip airbags are arranged along the length of the body and are evenly distributed along the circumference of the abdomen. Several vertical strip airbags can completely wrap the abdomen to ensure that the air pressure is evenly applied to the patient's abdomen. The expansion of the abdomen is caused by the downward compression of the diaphragm. After the diaphragm expands, the gas in the abdomen moves from bottom to top or from top to bottom. Therefore, vertical strip airbags are arranged. After the gas is introduced, the gas can move vertically along the vertical strip airbags to simulate the actual expansion of the abdomen.

[0026] The first airbag 2 and the second airbag 3 are correspondingly arranged on the back of the vest body 1. The back airbag and the front airbag can wrap the abdomen and chest of the patient at the same time to ensure the uniformity of the airbag gas after gas input.

[0027] The first air port 4 is connected to the main air pump 6 through the trachea, and the second air port 5 is connected to the auxiliary air pump 7 through the trachea. The auxiliary air pump 7 and the main air pump 6 are respectively connected to the first airbag 2 and the second airbag 3 through the trachea, so that the first airbag 2 and the second airbag 3 can input different air volumes, thereby forming different volumes in the abdomen and chest.

[0028] A collar 8 is arranged on the top of the vest body 1, cuffs 9 are arranged on both sides of the vest body 1, and three rows of Velcro 10 are arranged below the collar 8 of the vest body 1 and in the center of the vest. When the patient wears the vest, the arm passes through the cuff 9 and the head passes through the collar 8, and then the Velcro 10 is fastened to complete the wearing. Elastic bandages 11 are arranged at the connection between the vest body and both sides of the back to increase the comfort of the patient.

[0029] Embodiment 2:

[0030] The training method of the pneumatic breathing training vest is as follows: first, the patient wears the vest, and after the 10 buttons are fastened,

[0031] The first airbag 2 is set corresponding to the chest cavity, and the second airbag 3 is set corresponding to the abdominal cavity. At this time, the area between the first airbag 2 and the second airbag 3 corresponds to the patient's diaphragm. First, the main air pump 6 is turned on to provide air pressure for the first airbag 2, and the auxiliary air pump 7 is turned off. At this time, the chest cavity is squeezed, the chest cavity muscles are compressed, the chest cavity volume is reduced, and exhalation is completed. Then the main air pump is turned off, and the auxiliary air pump 7 is turned on to provide air pressure for the second airbag 3. At this time, the abdominal cavity is squeezed, the abdominal cavity muscles are compressed, and the abdominal cavity volume is reduced to complete inhalation. The airflow is used to change the volume of the airbag, and then the airbag squeezes the volume of the chest cavity or the abdominal cavity. While the volume changes, the chest cavity or the abdominal cavity muscles are repeatedly compressed to simulate lung function training, such as abdominal breathing, so as to enhance the strength and endurance of the respiratory muscles. The main air pump 6 and the auxiliary air pump 7 are inflated alternately to complete the exhalation and inhalation functions. Even if the patient cannot breathe independently, the respiratory muscles can be trained to improve the muscle strength and endurance of the respiratory muscles through the contraction or expansion of the rebound force of the air pressure in the chest cavity.

[0032] The main air pump 6 and the auxiliary air pump 7 are alternately inflated, and the inflation pressure is maintained between 4 bar and 4.5 bar. The pressure during the cyclic alternating working process should be controlled within the range of 4.8 bar to 5.0 bar.

[0033] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
