  • a passive respiratory device i.e. of the type having no mechanical ventilation devices.
  • the device as described hereinafter is particularly suitable for breathing exercise, aimed at exercising the muscles of respiration (i.e. the muscles of inhalation and exhalation), namely the accessory muscles of respiration.
  • the "accessory muscles of respiration” are intended as the muscles (of inhalation and exhalation) involved in forced respiration.
  • the device as described hereinafter can also increase oxygen saturation in blood.
  • the use of the device as described hereinafter can also add volume and elasticity to bronchi, bronchioles and alveoli.
  • the device as described hereinafter is suitable to provide indications about certain lung parameters, such as instantaneous inhalation and exhalation flow rates.
  • the device as described herein may be also useful to obtain an indication of lung capacity and resistance to exhalation.
  • US 4 171 804 , US 2014/150801 and US 9 561 399 B2 disclose devices for exercising exhalation muscles, namely the accessory muscles of exhalation.
  • US 3 898 987 discloses a device for measuring the volume of air inhaled by a patient.
  • US 3 898 987 can be used both in natural breathing conditions and when supplementing the activity of the muscles of respiration with a positive-pressure mechanical ventilation device.

  • the device 1 comprises a chamber 2 which extends along a substantially vertical.axis X.
  • the chamber 2 has a lower end 3 and an upper end 4.
  • the chamber 2 has rigid walls and hence maintains a constant volume during the operation of the device 1.
  • the lower end 3 of the chamber 2 communicates with a first air inflow opening 31, for the inflow of exhaled air and with a second air inflow opening 32 for the inflow of inhaled air.

  • a body is provided in the chamber 2, between the lower end 3 and the upper end 4, and is vertically movable upwards when impinged upon by the inhaled or exhaled air that rises through the chamber 2, against its own weight force.
  • the flow of air inhaled and exhaled by the patient directly contacts the moving body 5 which impedes the flow of air in the chamber 2 and forces the user to exercise the accessory muscles of inhalation and exhalation, namely the muscles of forced respiration.
  • the position reached by the moving body 5 may be indicative of the performance of the respiratory system of the patient, e.g. of the inhalation and exhalation flow rates.
  • the device 1 is equipped with a duct 6 (connected to the mouth of the patient) which is used to inhale and exhale the air that flows through the chamber 2 and impinges upon the moving body 5.
  • the duct 6 is in communication with the first inflow opening 31 (for the inflow of exhaled air into the chamber 2) and with the second outflow opening 42 (to allow the outflow of inhaled air from the chamber 2).

  • the air flow generated in the chamber 2 is directed upwards during both inhalation and exhalation.
  • the chamber 2 has a frustoconical profile and the height reached by the moving body 5 in the chamber 2 is related to the flow rate of the air that flows through the chamber 2.
  • the moving body 5 takes a position of equilibrium when its weight is balanced by the thrust of the air flow.

  • a hollow body 23 e.g. a body having a cylindrical outer shape
  • the chamber 2 has an upwardly increasing tapered cross section, e.g. a frustoconical section, and the moving body 4 has a generally spherical form.
  • the moving body 5 in the chamber 2 acts as a variable-area flowmeter or rotameter.
  • the moving body 5 opposes resistance to the air that flows in chamber 2 and forces the user to use the muscles of inhalation and exhalation.
  • the maximum height that can be reached by the moving body 5 provides an indication of the maximum lung capacity of the user in the inhalation phase and in the exhalation phase.
  • the moving body 5 remains in the lifted position for a time that is proportional to the maximum capacity of the lungs of the user.
  • the hollow body 23 is encircled by a second hollow body 8, also made of transparent material, thereby defining an annular chamber 81 that surrounds the chamber 2.
  • the hollow body 23 and the hollow body 8 are two coaxial tubular elements closed at the top by a cap 85.
  • the cap 85 may be joined to the upper end of the hollow body 8 by means of seals (not shown) to ensure air-tightness.
  • the hollow body 8 is closed at its top.
  • the annular chamber 81 communicates at its top with the upper end 4 of the chamber 2 via at least one opening 231 formed in the upper part of the hollow body 23.
  • the chamber 81 communicates with the first air outflow opening 41 for the outflow of exhaled air, and with the second air outflow opening 42 for the outflow of inhaled air.
  • the exhaled air that flows out of the first outflow opening 41 flows through the second non-return valve 741, whereas the inhaled air that flows out of the second outflow opening 42 flows through the fourth non-return valve 742.
  • the device 1 may comprise a graded scale 18 to determine the vertical position of the moving body 5.
