Description
Technical field:
The present invention relates to a kind of mouthful, nose aeration monitoring device of autonomous respiration mode, belong to the biomedical engineering technology field.
Background technology:
The process of general autonomous respiration monitoring adopts the tested patient's of face shield method continuous monitoring venting pressure, and capacity, flow rate, compliance and resistance are main multinomial ventilatory function index.Evaluation to ventilate unusual diagnosis and therapeutic effect plays an important role.Autonomous respiration mode ventilation is both at home and abroad at present monitored except that satisfying general the measurement the monitoring requirement; In following several respects bigger improvement is arranged: 1, high accuracy; Sensitivity: utilize computer technology to calculate relevant parameter and curve timely and accurately; Like compliance, PV ring, FV ring, FEVi% etc., to diagnosis and guiding treatment at the right time with intuitively.2, ageing: as to provide the circular chart variation and point out discovery gas leakage and air leakage with showing different parameters in a flash, observe aeration status and ventilate not normal.3, the availability of data: as provide the comparison with normalized curve, the comparison before and after the treatment supplies teaching and clinical model function.3, convenience: easy to carry, easy to use and tested patient's comfortableness.
In the process of autonomous respiration monitoring, airway resistance produces considerable influence to measurement result, and the present monitoring face shields that use close method more or the face shield open circulit ethods can not reflect through port, nasal respiration respectively fully or mix the ventilation truth under the breathing situation.
Through the document retrieval, do not find the mouth identical, the relevant public reported of nose aeration monitoring device of autonomous respiration mode with technical scheme of the present invention.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, can differentiate the aeration monitoring device under difference through port, nasal respiration or the mixing breathing situation under autonomous respiration mode and provide a kind of.
Of the present invention mouthful, nose aeration monitoring device of autonomous respiration mode is by the cylinder (1) that has 3 semi-circular groove (2) on the outer by 120 degree angles, and 3 the Dliter measuring tubes (12) that embed semi-circular groove (2) constitute; Wherein: have the rectangular channel (3) that is used to place Dliter pipe signal plug and signal processing circuit board (4) under 3 semi-circular groove (2); Have in the Dliter pipe meet flow to direction and adverse current to direction be 90 spend bent angles 2 tubules (7,8); Cylinder (1) center has aperture (6); Rectangular channel (3) bottom has circular hole (5); Attachment head on the Dliter measuring tube (13) and air entraining pipe (14), the connection between the 3 block signal treatment circuit plates (4) is picked out through the circular hole (5) of rectangular channel (3) bottom and the central small hole (6) of cylinder (1) by electric wire.
Have in Dliter measuring tube of the present invention (12) pipe to meet and flow to direction and adverse current and 90 spend 2 tubules of bent angle (7,8) to being of direction.The outer plane, hole of tubule sticks with glue and connects piezoresistance sensor (10), and sensor conductor inserts the signal processing circuit board (4) of planar circular semi-circular groove (2) through plug (9) on the Dliter measuring tube.Adorning disc valve (11) on the Dliter measuring tube is used to open or closes this measuring tube.Attachment head on the Dliter measuring tube (13) and air entraining pipe (14).Treatment circuit of the present invention, each the road signal that is collected by different Dliter measuring tubes changes pressure difference signal and the voltage signal of exhaling through in managing, air-breathing speed is directly proportional into through the balanced bridge amplifier.Signal inserts low pass filter, and elimination high frequency composition is sent into signal processing circuit and exported tested patient's mouth, nasal respiration or mix venting pressure under the breathing situation, capacity, flow rate, compliance, reaches the multinomial ventilatory function index of resistance.
The used device of this method is that market is bought basically.That piezoresistance sensor has is highly sensitive, the response fast, precision is high, operating temperature range is wide, good stability, easy to use and be easy to mass-producted characteristics.Piezoresistance sensor is as the corresponding both sides of electric bridge during the signal input, and output voltage is directly proportional with the pressure and the supply voltage of effuser inner fluid with the inflow pipe inner fluid.Switch amplifying circuit in the signal processing circuit board, signal processing circuit and computing formula are public technology.
That the present invention has is simple in structure, the advantage of definite functions.Can obviously distinguish the ventilation monitoring result under difference through port, nasal respiration or the mixing breathing situation under autonomous respiration mode, reflection measured's true breathing situation.
