Utility model content
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and safe respirator.
The technical scheme that this utility model adopts is: a kind of respirator, comprise the air oxygen blender being communicated with by conduit one, biofilter and air storage bag, the inspiratory flow sensor being communicated with by conduit two, inspiratory pressure sensor and temperature and humidity regulator, the breath pressure sensor and the expiratory flow sensor that are communicated with by exhaust tube; Described conduit one and conduit two are communicated with, described conduit two, and exhaust tube connects suction nozzle by threeway; The equipped at outlet port of described air oxygen blender is provided with intake valve; The outlet of described conduit one is provided with relief valve; The equipped at outlet port of described inspiratory flow sensor is provided with inlet valve; The outlet of described exhaust tube is provided with outlet valve; The end of described suction nozzle connects breathing mask or breathing hose; Described inspiratory flow sensor, inlet valve, expiratory flow sensor is all connected with controller by wire with outlet valve; Described inspiratory pressure sensor is all connected with alarm by wire with breath pressure sensor.
Aforesaid biofilter is activated charcoal strainer.
Aforesaid activated charcoal strainer assembling ature of coal charcoal or coconut husk charcoal.
Aforesaid inlet valve and outlet valve pass through step motor drive.
Aforesaid controller is provided with control panel.
Aforesaid air storage bag is connected with Pressure gauge.
By adopting above-mentioned technological means, advantage of the present utility model is: intake valve and relief valve are set, according to the Pressure gauge being connected with air storage bag, judge make-up gas or aerofluxus, keep air storage bag internal pressure constant, guarantee to breathe safety; Activated carbon filtration material has efficient absorption property, can process and contain benzene class, phenols, alcohols, the organic gas such as aldehydes and foul gas and contain all kinds of gas of micro heavy, in deodorization, aspect eliminates the unusual smell, there is good clean-up effect, and waste gas is carried out to Adsorption Concentration, after purification, can directly discharge; By the Real-Time Monitoring of flow transducer, air-breathing and expiration are adjusted; By the Real-Time Monitoring of pressure transducer, in the time of pressure limit, trigger alarm in time.This utility model is simple in structure, easy to operate, and performance is more stable, is not easy to break down, and is applicable to being widely used of hospital and family.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of this utility model respirator.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1, respirator of the present utility model, comprise the air oxygen blender being communicated with by conduit 1, biofilter and air storage bag, the inspiratory flow sensor being communicated with by conduit 23, inspiratory pressure sensor and temperature and humidity regulator, the breath pressure sensor and the expiratory flow sensor that are communicated with by exhaust tube 7; Described conduit 1 and conduit 23 are communicated with, described conduit 23, and exhaust tube 7 connects suction nozzle 5 by threeway 6; The equipped at outlet port of described air oxygen blender is provided with intake valve 1; The outlet of described conduit one is provided with relief valve 9; The equipped at outlet port of described inspiratory flow sensor is provided with inlet valve 4; The outlet of described exhaust tube is provided with outlet valve 8; The end of described suction nozzle 5 connects breathing mask or breathing hose; Described inspiratory flow sensor, inlet valve 4, expiratory flow sensor is all connected with controller by wire with outlet valve 8; Described inspiratory pressure sensor is all connected with alarm by wire with breath pressure sensor.
The air source of air oxygen blender of the present utility model is provided by air compressor, source of oxygen is provided by oxygen cylinder, air, two strands of gases of oxygen are mixed into the mist that meets oxygen concentration standard, then be delivered to biofilter via conduit 1, after purification filtering, be delivered to air storage bag, be provided with intake valve 1 at the equipped at outlet port of air oxygen blender, for controlling conveying or the disconnection of mist, biofilter adopts activated charcoal strainer, activated charcoal strainer can be assembled ature of coal charcoal or coconut husk charcoal, the exit of conduit 1 is provided with relief valve 9, pressure in air storage bag is indicated by Pressure gauge 10, in the time that pressure exceedes established standards, relief valve 9 is opened automatically, carry out aerofluxus, in the time of air storage bag output gas, spring-compressed air bag in air storage bag, intake valve 1 is opened simultaneously, make-up gas, in the time that air storage bag stops exporting gas, intake valve 1 cuts out, make the pressure in air storage bag keep substantially constant.In course of normal operation, relief valve 9 is in closed condition, convert the needed voltage signal of controller suction modulation from air storage bag mist out to through inspiratory flow sensor, then enter inspiratory pressure sensor through inlet valve 4, convert the needed pressure signal of alarm to, enter temperature and humidity regulator, in temperature and humidity regulator, mist is by humidifying and heat to the needed temperature of human body, then enter breathing mask or breathing hose by suction nozzle 5, for patient; The gas that patient breathes out enters suction nozzle 5 through breathing mask or breathing hose, then be transformed into controller and exhale and regulate voltage signal used by exhaust tube 7 expiratory flow sensor of flowing through, enter breath pressure sensor, convert the needed pressure signal of alarm to, outside outlet valve 8 eliminating machines.
