Description

Respiratory muscle training and power surveying device

The present invention relates to a kind of human body respiration flesh and take exercise and the dynamometry device, can carry out the adjustable exercise of intensity respectively or simultaneously to inspiratory muscles and expiratory muscle, also can measure or assess the contractility and the endurance of respiratory muscle with it with it.

Respiratory muscle claims the pump of ventilating again, and is the same with circulating pump (heart), the motion that is not all stopping throughout one's life.Respiratory muscle function mainly shows the size of contractility and endurance.The respiratory muscle force measurement is medically significant.Respiratory muscle is the same with skeletal muscle, can strengthen its contractility and endurance by taking exercise.Since nineteen eighty-two, the U.S. two companies and Japanese a company, successively produced three kinds of inspiratory muscles exercisers, can (Chest) roll up 19 pages of 4 phases and " H﹠L magazine " (Heart and Lung) in 1987 91 referring to U.S.'s " division of chest disease's magazine " and roll up 335 pages of 4 phases in 1984 13." Japanese chest Society of Surgery magazine " be 1987 35 2 phases of volume (JJATS).The respiratory muscle training device of China's invention is held concurrently and can be performed physical exercise number of patent application 85201123 to inspiratory muscles and/or expiratory muscle.Confirm that through clinical practice its clinical total effective rate reaches 97.14%.These devices increase respiratory resistance by the aperture in parallel of regulating 4-6 different apertures, and exercise intensity is less than 6 grades.Because the resistance spectral limit is little, branch is thicker, is unsuitable for being used for respiratory muscle force measurement or assessment.These devices need to install rotating resistance adjustment disk, and production technology is complicated, damages easily, and cost is higher.

Task of the present invention provides a kind ofly both can carry out respiratory muscle training, can measure the device of respiratory muscle strength again.Oxygen uptake can be carried out simultaneously with exercise.Cancel traditional resistance adjustment disk, make more compact structure more reasonable, be more suitable for suitability for industrialized production, thus also smaller and more exquisite more durable.

This task is finished as follows: 12-15 resistance hole is machined directly on the cylinder of this device garden, and the two ends of breathing valve at combination type increase an air-breathing passage and an expiration passage respectively.Passage is distributed on the concentric garden with resistance hole, and valve or this device body are breathed in coaxial rotation, select required resistance hole.Because the garden cylinder of body is equivalent to the girth in body cross section, more much bigger than drillable area on traditional resistance adjustment disk plane, the resistance hole count can double, the also corresponding expansion of resistance spectral limit, not only can increase the scope and the class of exercise intensity, and can be used for breathing dynamometry in a big way.Air-breathing passage links to each other with the oxygen therapy joint, can oxygen uptake when taking exercise.Below in conjunction with accompanying drawing, be described in detail its structure.Fig. 1 is a kind of longitudinal sectional drawing of concrete structure, and Fig. 2 is a resistance hole local expanded view partly.

With reference to Fig. 1, the body of this device (1) is the plastic conduit of long 4-5cm, external diameter 2.4-2.6cm, internal diameter 2.0-2.2cm.One end and mask (2) join.Mask (2) is ellipse garden shape, and is flexible slightly, conforms to the degree of lip-rounding.The other end joins with breathing valve (3), and inserting the part of breathing in the valve (3), processes 12-15 resistance hole (4).With reference to Fig. 2, each resistance hole (4) is distributed on the concentric garden, pitch of holes 0.4-0.7cm.Each resistance hole (4) garden heart equates apart from the Edge Distance of body (1).Each resistance hole (4) is pressed pore size circular array successively, and the minimum-value aperture is 0.1cm, and the maximum diameter of hole is 0.6cm.In air velocity is 40Lmin ^-1Under the condition, measure the Resistance Value of each resistance hole (4) respectively, and this numerical value is printed on corresponding resistance hole (4) one sides, constitute one group of resistance numerical tabular.

With reference to Fig. 1, to breathe valve (3) and make with flexible, transparent or semitransparent slightly plastics, two ends all can be enclosed within on the body (1) securely.One end has air-breathing passage (5), and the other end has expiration passage (6).Two holes (5,6) equate diameter 0.6～0.7cm apart from the lateral border distance of breathing valve (3).Body (1) with breathe valve (3) and be connected after, coaxial rotation can make passage (5,6) and resistance hole (4) the garden heart that aligns successively.Breathing valve (3) has valve shelves (7) and valve film (8), and the two external diameter is identical with body (1) internal diameter.The thick 0.3cm of valve shelves (7), on 4 apertures are arranged is the gas port of 0.5-0.6cm (9).The thick 0.1cm of film (8) is made by the rubber or the latex of good springiness.Air-breathing passage (5) is near valve shelves (7) one sides, and expiration passage (6) is near film (8) one sides.For easy to use, can near passage (5,6), print " air-breathing " or " expiration " printed words respectively.Air-breathing passage (5) is connected with oxygen suction connector (10).The long 0.5-1.0cm of the latter (10) is internal diameter and the identical straight tube of air-breathing passage (5).Wall thickness 0.1-0.15cm.

According to above-mentioned similar principle, also passage (5,6) can be processed on body (1), and respectively be processed one group of resistance hole (4) at breathing valve (3) two ends.

During use, lip is covered mouth breathing with mask (2).When valve film (8) is outside valve shelves (7), is used for inspiratory muscles and takes exercise or dynamometry.When air-breathing, air-flow is pressed in film (8) on the valve shelves (7), and air-flow can only enter body (1) intracavity by the resistance hole (4) that chooses on oxygen suction connector (10), air-breathing passage (5) and the body (1), enters human body through mask (2).At this moment, inspiratory muscles will additionally do work, and overcomes the inspiratory resistance of increase.Resistance size (being the inspiratory muscles exercise intensity) is controlled by resistance hole (4).During expiration, air-flow enters body (1) intracavity by mask (2), by the gas port (9) on the valve shelves (7) film (8) is pushed open and is discharged.The minute quantity air-flow is overflowed simultaneously by air-breathing passage (5).So gas-flow resistance is minimum when exhaling, the resistance that resistance hole (4) produces only acts on inspiratory muscles.If under the oxygen uptake situation, take exercise, then oxygen is imported by oxygen suction connector (10).

To breathe valve (3) and unload, and be enclosed within again after putting upside down on the body (1), then valve film (8) is positioned at valve shelves (7) inboard, is used for expiratory muscle and takes exercise and dynamometry.

Be used for measuring when exhaling (suction) gas myotility size, according to the age and the health of user, the suitable resistance hole (4) of preliminary election aligns with exhaling (suction) gas passage (6,5).Allow the continuous mouth breathing of user (also can use nose clip) 5 times (or continue to breathe a minute, down with),, then resistance hole (4) is turned down, increase resistance if user can be finished smoothly; Otherwise, then transfer greatly, reduce resistance.Feel to exhale (suction) gas to require great effort especially up to user, breathe but can continue 5 times.Called out most (suction) gas myotility when this moment, resistance hole (4) pairing Resistance Value was then breathed for this people is gentle.Select to breathe the docking calculation of valve (3) and body (1), then can measure expiratory muscle contractility and inspiratory muscles contractility respectively.

When being used to measure respiratory muscle endurance size, sex, age according to user are selected suitable resistance hole (4), its Resistance Value should be than the little one-level of maximum shrinkage force (about about 70%), the record user can be under this kind respiratory resistance, the maximum duration of continue breathing (minute to be unit) can be judged the endurance size of this people's expiratory muscle or inspiratory muscles.The respiratory muscle maximum shrinkage force of relevant different sexes, age groups and normal value, the measuring technique of endurance can be with reference to relevant medical science monographs.The data that this description is quoted can be for reference.

When carrying out respiratory muscle training, should take exercise 5-15 minute from bigger resistance hole (4) at every turn, treat that respiratory muscle strength increases after, turn resistance hole (4) down one-level one by one, continue to take exercise.The a few days is used in every hole, more than accumulation is taken exercise all around.

The present invention has carried out preferred to the resistance spectrum on the basis of the respiratory muscle contractility of having analyzed each age group crowd under domestic and international different sexes, the different health status and endurance.Domestic and international existing respiratory muscle training device there is following improvement: cancelled resistance adjustment disk and corresponding fixing spring and double-screw bolt etc., resistance hole (4) is machined directly on body (1) the one end garden cylinder, parts are obviously reduced, and make body (1) shorten 30%, be convenient to produce, reduce cost, smaller and more exquisite durable.It is less to have overcome resistance adjustment disk cross section simultaneously, can not hold the defective of more resistance holes, and making to increase for the area of processing resistance hole, and the class of resistance hole number and adjusting exercise intensity is also obviously increased, and has enlarged range of application.And can be used for the maximum shrinkage force of inspiratory muscles and expiratory muscle and the measurement of endurance, realize one-object-many-purposes.In addition, oxygen uptake can be carried out simultaneously with exercise.This device is suitable for normal person and patient's respiratory muscle training and the measurement of respiratory muscle strength identifies in fields such as respiratory clinic, rehabilitation medicine, preventive medicine and sports medical science, purposes is more widely arranged.
