Abstract
The utility model relates to a high frequency oscillating respirator, which comprises an air current source of high frequency, a connection pipe (7), a low passing pipe (8), a pressure gauge (10), a tachometer (12) and a tracheal cannula (11). The air current source of high frequency comprises an electric motor (3), a fly wheel (2), a connection rod (4) and an air chamber (5) or a linear electric motor (20) or the air chamber (5). Compared with the high-frequency respirator in an acoustic horn type, the high-frequency oscillation respirator adopts the electric motor to replace voice coils and thus a strong flow quantity amplitude is obtained. Compared with the respirator in a piston type, a rubber membrane replaces the piston and thus the noise is reduced. The high frequency oscillating respirator has adjustable air current frequency between 1 to 15Hz and adjustable amplitude between 50 ml to 400 ml with the advantages of large air current amplitude and low noise. The utility model is suitable for the animal experiment and the treatment of the respiratory distress syndrome of the medical clinic.
Description
This utility model relates to a kind of high-frequency oscillation breath machine.
Respiratory distress syndrome is a critical illness clinically.One of major measure of treatment is to carry out the mechanical ventilation support.The ventilatory frequency of conventional respirator uses this class artificial respirator below 1Hz, the mortality rate of adult respiratory distress syndrome still can be up to 50%.For this reason, seek more effective ventilating mode and just become key.Frequency is a kind of ventilating mode that is different from conventional mechanical ventilation fully that grows up over past ten years at 1Hz～15Hz or higher HFO.Carried out big quantity research abroad.Experimental result shows that this ventilating mode has gratifying ventilatory effect, and Preliminary Applications in infant respiratory distress syndrome.Interrelate therewith, the research of high-frequency oscillation breath machine just becomes an important problem.
Present employed open high-frequency oscillation breath machine can be divided into two classes by the difference of vibration source of the gas.One class produces oscillating air flow by loudspeaker, another kind ofly moves forward and backward the generation oscillating air flow by piston.Last class respirator is only applicable to the toy experiment because the air-flow amplitude is too little; Though back one class can produce the air-flow of large amplitude, noise is too big, is not accepted by patient, should not promote clinically.
The purpose of this utility model provides a kind of air flow amplitude, low noise high-frequency oscillation breath machine, and it is made up of higher-order of oscillation air flow source, connection tube, low siphunculus, tachometer, piezometer and tracheal intubation.The feature of higher-order of oscillation air flow source is: it is made up of motor, flywheel, movable rod and air chamber, perhaps is made up of linear electric motors and air chamber.The upper bottom surface of air chamber is a rubber membrane, and the air chamber side has the gas outlet, and remainder seals.The driven by motor flywheel, flywheel is connected with the rubber membrane of air chamber through connecting rod, metal rack, or is connected with rubber membrane through metal rack by linear electric motors, rubber membrane up-down vibration when motor rotation or linear electric motors start, the air chamber gas outlet just has oscillating air flow to flow out.The frequency of oscillating air flow is regulated by the change of motor speed or linear electric motors reciprocating frequence, the amplitude of oscillating air flow by connecting rod on flywheel the position or the change of linear electric motors stroke regulate.The oscillating air flow frequency is adjustable between 1Hz～15Hz, and amplitude is adjustable between 50ml～400ml.Rubber membrane in the higher-order of oscillation air flow source is characterized in that periphery has one group of ripple, and mid portion is lined with a foil, and the foil center connects a metal rack, and a miniature bearing is installed on the support, and the optimum thickness of foil is between 0.1mm～1.5mm.When using motor, rubber membrane is connected with flywheel through metal rack, connecting rod, it is characterized in that the miniature bearing on the connecting rod one termination support, and the other end is connected with slide block through a miniature bearing, slide block set is on the tongue of flywheel, and the position of slide block is regulated by the screw of its both sides and be fixing.Tongue is fixed together by flywheel center and flywheel.When using linear electric motors to form the high-frequency air flow source, it is characterized in that the metal rack of linear electric motors on rubber membrane is connected with rubber membrane.
Communicated with low siphunculus through connection tube by the effusive high-frequency air flow in high-frequency air flow source, after tracheal intubation output, it is characterized in that tracheal intubation axially installs along connection tube, low siphunculus is vertical with connection tube, and low siphunculus offside is installed a fresh air inlet and managed.Connection tube is that internal diameter is not less than the heavy wall plastic tube that 12mm length is not more than 70cm, wall thickness 1mm～2mm.Low siphunculus is internal diameter 10～15mm, the plastic tube of long 100cm～500cm, and its effect is to provide low frequency channel for expellant gas in fresh air and people (animal) body.Piezometer is in order to show airway pressure, and tracheal intubation is used for being connected with people (animal) respiratory system.Fresh air is by fresh air inlet pipe input.
This utility model is compared with the piston type high-frequency oscillation breath machine, replaced moving forward and backward of cylinder with the rubber vibration of membrane, thereby noise reduces greatly; Compare with the horn high frequency respirator,, replace the motion of voice coil loudspeaker voice coil in magnetic field, thereby improved the amplitude of high-frequency air flow with motor-driven rubber membrane up-down vibration.It is low to the utlity model has under high frequency noise, and the advantage that the high-frequency air flow amplitude is big is suitable for clinical use, is applicable to the large animal experiment.
