Description

Respiratory muscle exerciser

Technical Field

The invention relates to a medical rehabilitation apparatus, in particular to an apparatus suitable for exercising muscles of the upper and lower parts of a respiratory system.

Background

Chronic respiratory diseases are now one of four major chronic diseases seriously harming national health, many chronic respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD), severe tuberculosis, pulmonary fibrosis, obstructive sleep apnea syndrome and the like, the damage to lung function is serious, and the quality of life of patients is reduced, and because the causes of the diseases are difficult to remove, once the diseases are ill, the diseases are difficult to cure, and it is almost impossible to expect to improve the quality of life of patients by treatment for removing the causes. The development of the disease course can be delayed only by medicines or other technical means, and one important technical means is respiratory function exercise, namely, the respiratory function exercise is realized by using some instruments to exercise the respiratory related muscle groups of the patient, so that the respiratory functions of the upper and lower parts of the respiratory system of the patient are enhanced, the function lost due to the damage of the respiratory system tissues is compensated to a certain extent, and the life quality of the patient is improved. In addition to chronic lung diseases, other diseases other than the lung itself may also cause decreased lung capacity, decreased lung function, for example; the upper abdominal operation, long-term bed rest, stroke, brain injury and the like, the function of central or peripheral muscles is weakened, so that the respiration amplitude is reduced, the ventilation volume is reduced, the oxygen supply of tissues and organs of the whole body is insufficient, a series of clinical manifestations and immunity decline are generated, further more health problems are caused, and the vicious circle is formed. The etiology of these patients is difficult to remove in a short time, and it is impossible to expect the lung function to recover naturally in a short time, so that these patients also need to enhance the function of respiratory muscle, increase the ventilation capacity of lung, ensure sufficient oxygen supply of body tissues and organs, and block the above-mentioned vicious circle by external force.

The most common and effective technique for respiratory tract function enhancement, including lung function, is the use of breathing trainers. Many respiration trainers are available on the market at present, such as imported PowerBreathe, homemade Shengchang SC-A respiration trainers, Shu Hu le and Fu respiration function trainers, and ancient early single ball instruments, three ball instruments and the like; there are some devices which have not been commercialized for a while, and have already been patented with good creativity, such as "respiratory muscle trainer" with patent number 201320347213.2, "a parallel type inhalation and exhalation breath trainer" with patent number 201721364033.X, and the like. The basic principles of operation of these instruments are the same or similar: the purpose of exercising the respiratory muscles is achieved by the respiratory muscles to resist the resistance of an external airway in the processes of inspiration and expiration. There are various methods for creating resistance in an external airway, and as a summary, there are two main basic substances used: the elastic elements and the liquids, in particular the elastic elements, are used most frequently.

The basic principle that an exercise machine can be used, wanted and liked by the general public is amphipathy: effectiveness and interest, and secondly, low cost. The basic principle of the operation of the apparatus of the present invention is similar to that of the above products or patents, and the respiratory muscles of the upper and lower respiratory tracts of a user are required to overcome the resistance of the external airway so as to exercise the respiratory muscles. The external air passage resistance generating and adjusting device used by the invention is different from all products on the market and products not on the market at present, so that the external air passage resistance is generated and adjusted more finely and linearly; the invention is more interesting and effective.

At this point, the assembly of the exhalation module is complete.

The connection and the use of the whole machine are as follows: a host air pipe air outlet a0101 is connected with an expiration check T-shaped pipe air inlet b0206 through a threaded pipe, a man-machine interface is connected with an expiration check T-shaped pipe air outlet b0202, a sleeve b0101 thread b0102 of an expiration module is screwed into an expiration check T-shaped pipe connecting thread b0209, the two components are integrated, and finally a pressure difference sensor connecting pipe orifice b0205 on the expiration check T-shaped pipe b0201 is connected with a connecting pipe (not shown) which is inserted into a reserved expansion hole (an expiration pressure measuring hole) c0105 on the surface of an electronic box in advance through a hose. Thus, the machine of example 1 of the present invention was assembled.

The use of the invention: and (3) turning on a power switch a0505 in the base c0501, immediately supplying power to the bidirectional differential pressure sensor and a matched display screen by the power supply, and displaying the current pressure value in the gas circuit by the display screen, wherein the current pressure value is usually preset to be zero. An appropriate human machine interface is selected and connected with the machine according to the exercise purpose and the use habit of the user. The sound source selection switch a0503 is adjusted to select a short audio preferred by the user. The position of the sliding regulator a0401 is adjusted to enable the tension spring to be properly stretched, a user enables the man-machine interface to be in close butt joint with the mouth and the nose, the user inhales air forcibly, negative pressure is generated in an air path between the man-machine interface and the resistance cover a0213, pressure difference is formed between the negative pressure and the external atmospheric pressure, when the difference value reaches the opening threshold value of the resistance cover a0213, the external air reaches the resistance cover seat a0211 through an air inlet hole of the connecting plate c0301 and an air inlet hole of the resistance base plate a0212, the tension force of the tension spring is overcome, the resistance cover a0213 is pushed open, the air enters the air collecting pipe, the air with medicine flavor is upwards penetrated through a cotton pad in a horn mouth of the medicine gas generator a0201 to form air with medicine flavor, the air flows out of the air outlet a0101 of the air conveying pipe through an air inlet a0105 at the bottom. In the process, when the resistance cover a0213 is pushed open, the contactor a0215 on the upper surface pushes the key head a0253 of the customized single-action piece light touch switch upwards, the key head a0253 moves upwards to drive the inner part a0252 of the key box to move upwards, the movable electrode contact a0251 is contacted with the fixed electrode a0248, the current from the output end of the power switch is transmitted to the movable electrode contact a0251 through the movable electrode contact a0254, the inner shaft support a0249, the U-shaped spring piece a0246, the U-shaped spring piece platform a0257 and the inner shaft a0250 together, then transmitted to the fixed electrode contact a0255 through the fixed electrode a0248, and finally transmitted to the effector through a lead to light the LED lamp on the surface of the electronic box, and simultaneously the voice module is electrified to work, the micro-speaker emits preset voice, adjusts the control handle of the selection switch a0503, and the speaker emits different voice sources. Along with the increasing of the inspiration force of the user, the upward rotation angle of the resistance cover a0213 is increased gradually, the pressure on the tact switch also continues to increase, while the moving electrode contact a0251 remains in contact with the fixed electrode a0248, the switch rotates along a rotating shaft formed by an outer shaft seat a0244 of the tact switch 2, an outer shaft hole a0245 of the tact switch 2 and a metal shaft, the tact switch can not form obvious obstruction for opening the resistance cover a0213, when the inhalation action of the user reaches the limit, the inhalation airflow is gradually reduced, the negative pressure in the air passage is reduced, when the negative pressure is not enough to support the opening of the resistance cover a0213, the tact switch 2 returns to the original position under the action of the reset spring piece and the cooperation of a stopper (not shown), the resistance cover a0213 is under the action of the tension spring, and when the resistance cover seat a0211 is closed, the internal contact of the tact switch is disconnected, the LED lamp in the electronic box is turned off, the sound of the loudspeaker disappears, and the numerical value of the gas circuit pressure display screen returns to the initial value. At this point, one inspiration exercise is completed. No matter whether the tact switch in the gas collecting pipe acts or not, the pressure sensor with high sensitivity can have corresponding current change when a user inhales, and the pressure display screen can display the changed pressure value in real time. Through the sound, light and digital changes, the user can clearly see the exercise effect of the user, so that the interest and the durability of the exercise are increased; the inhaled air with the medicinal smell is beneficial to the repair of the upper and lower respiratory tract mucosa lesions of a user. By moving the slide adjuster a0401 up and down, the length of the tension spring can be changed correspondingly, so that the pressure value of the opening of the resistance cover a0213 can be increased or decreased correspondingly to adapt to different users or different exercise stages of the same user.

When a user exhales with certain force, the reverse duckbill check valve in the exhalation blocking T-shaped pipe b0201 prevents exhaled gas from entering the threaded pipe, so that gas inlet and gas outlet are separated, and most pipelines are free of waste gas. The expired air is forced to enter the vertical pipe of the T-shaped pipe b0201, when the pressure exceeds the elastic force of the pressure spring b0108, the blocking cover b0107 of the pressure regulating valve core is pushed to move downwards, the expired air enters the pressure regulating valve core, passes through the groove-shaped air outlet holes in the side wall, passes through the semicircular air outlet holes b0112 and the fan-shaped air outlet holes b0105 downwards and is discharged into the atmosphere. Rotatory adjusting bolt b0110, the rotating head b0111 at its top drives movable cover b0109 and reciprocates, exerts different pressure for shutoff lid b0107 through pressure spring b0108, and the user just also need use different expiratory dynamics, just can discharge the waste gas to reach the purpose that exhales and take exercise. When the user exhales, expiration hinders contrary T-shaped pipe b0201 internal pressure and risees, and the gas circuit internal pressure of change passes through intercommunicating pore b0207, pressure sensor and connects mouth of pipe b0205, influences the pressure differential sensor in the electronic box, and the pressure display screen on electronic box surface can show the pressure value of exhaling in real time, and the user also can audio-visually see the effect when oneself exhales and take exercise.

When the user without oxygen deficiency exercises by using the invention, additional oxygen supply is not needed, so that the oxygen source is not needed to be connected. The oxygen inlet conduit port a0508 can be plugged with a plugging cap (not shown). When a user with oxygen deficiency exercises by using the oxygen supply device, an oxygen guide pipe connected with an oxygen source enters the base c0501 through the oxygen guide pipe inlet a0501 on the base c0501 and is connected with the oxygen input guide pipe interface a0508, when the oxygen supply device is used, the oxygen input quantity is adjusted according to different individual oxygen requirements by turning on the oxygen source flow switch, usually only a small amount of oxygen is needed, and the excessive oxygen can block the establishment of negative pressure of a gas path. Oxygen enters a pipeline in the connecting column c0201 through the connecting column oxygen seat a0507, upwards enters the medicine gas chamber through the oxygen interface a0102 in the box, forms mixed gas with the medicine gas, is inhaled by a user, and relieves the anoxic condition. The use of the present invention is not recommended for severe hypoxia patients.

Inspiratory function exercises (inspiratory modules) and expiratory function exercises (expiratory modules) are often used in combination, or each function may be used alone.

When the inspiration resistance exercise function is used alone, the expiration reverse blocking T-shaped pipe b0301 does not need to be connected. The threaded pipe is directly connected with the man-machine interface. Meanwhile, a blocking cover (not shown) is also needed to block the expiratory measurement tube a0107 in the electronic box.

If use external wireless pressure display screen, then do not need the screwed pipe, man-machine interface passes through the short hose and directly is connected with the gas-supply pipe gas outlet on the electronic box, and the handheld host computer of user trains.
