Description
This utility model relates to a kind of electron temperature-control humidifier, and this humidifier is mainly used in the humidifying of medical oxygen.
Humidifier commonly used has type breathing-machine humidification device and wall or humidifier, this class humidifier has a tank body, top pressure closure is housed on it, gas transmission mouth and oxygen input tube are housed on this top cover, be filled with distilled water in jar, patient's oxygen intake increases to some extent through its relative humidity after this humidifier humidifying, but the height of oxygen intake temperature is very big to patient's respiratory tract influence, and the air flue ciliary movement will be suppressed when temperature is lower than 30 ℃.And oxygen temperature is lower, and its relative humidity also be difficult for to improve, and therefore, needs a kind of humidifier that can heat to oxygen of design.
The purpose of this utility model is to provide a kind of electron temperature-control humidifier, and this humidifier can make on the stable predetermined value that is controlled between 30-35 ℃ of the temperature of air feed.
The purpose of this utility model is achieved in that a kind of electron temperature-control humidifier, tank body is arranged, top pressure closure is housed on it, gas output is housed on this top cover to be connect and chews and the oxygen input is taken over, described tank base is equipped with temperature sensor and internal heated type electric heated pipe, below the described tank body base is housed, is equipped with by voltage comparator in this base, the electronic temperature control circuit that three-state driver, alarm, bridge rectification power and bidirectional triode thyristor SCR constitute; The input and the temperature sensor of described voltage comparator (9) electrically connect; Three outfan T14, T2 of voltage comparator, T13 insert three input J11, J2, the J4 of three-state driver (10) respectively; The outfan J9 of three-state driver is through diode CR1 circuit input end taking alarm, and the outfan J18 of three-state driver and the control utmost point of bidirectional triode thyristor electrically connect, and another outfan J16 of three-state driver is connected to light emitting diode CR2.One termination power live wire of internal heated type electric heated pipe, the other end and bidirectional triode thyristor SCR anode electrically connect.Should in tank body, add quantitative distilled water before this utility model uses, and gas be exported gas is chewed, oxygen is imported adapter and connected with the pipeline that matches.Energized.This moment, electronic temperature control circuit started, temperature sensor is responsive to variations in temperature, and be converted into voltage signal, and deliver to voltage comparator, this comparator is differentiated the voltage signal of sending here, if level reaches alarm threshold, then send a signal of telecommunication to alarm, if level meets the thresholding of heating, then the double silicon control in adding circuit temperature sends a triggering signal and makes it conducting, then electrothermal tube begins to heat, when reach give fixed temperature after controllable silicon will turn-off voluntarily, stop to heat.An assurance jar intravital distilled water remains on and gives fixed temperature thus.
Because this utility model uses the electronic temperature control circuit control water temperature; thereby controlled the temperature of oxygen; its relative temperature can be greater than 80% when therefore oxygen was by this utility model; can make the patient respiratory road fully moistening; to nasopharynx, trachea and bronchus have protective effect, avoid the ciliated cell of dry cryogenic gas damage alveolar surfactant and respiratory tract; favourable cilia activity is discharged sputum easily.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, this utility model structure chart
Fig. 2, this utility model electrical schematic diagram
Referring to accompanying drawing, this utility model has a transparent tank body 1 with the engineering plastics injection mo(u)lding, top pressure closure 2 is threaded on it, rubber seal 3 is equipped with at a top cover and a jar mouthful place, be equipped with on the top cover gas output connect chew 4 and the oxygen input take over 5, this adapter extends to the tank body bottom, and temperature sensor 6 is housed in the bottom of tank body and internal heated type electric heated pipe 7, temperature sensor are critesistor.The shell of temperature sensor and electrothermal tube all selects for use the high-quality rustless steel to make.Tank body can hold water 700-800 milliliter, and a bonding hollow base 8 below the tank body is installed electronic temperature control circuit in it, and its appearance is provided with temperature and selects knob, burner on light, alarm lamp, power supply indicator etc.Electronic temperature control circuit comprises bridge rectification power 12, voltage comparator 9, three-state driver 10, alarm 11 and bidirectional triode thyristor SCR.Bridge rectification power provides the regulated power supply of 5 volts of direct currents to circuit.Be connected to light emitting diode CR4 in this circuit, as power supply indicator.Voltage comparator is selected the LM339 integrated package for use, connects a bleeder circuit of being made up of resistance R 1, R2, R3 at its input T8.Electrically connect with temperature sensor 6 after its input T9, T5, the T11 parallel connection; Select circuit to electrically connect with the temperature of being made up of resistance R 5, R6, R7 after its input T10, the T4 parallel connection, wherein variable resistance R6 and temperature are selected the knob interlock.Three outfan T14, T2 of voltage comparator, T13 insert three-state driver input J11, J2, J4, three-state driver respectively and select the 74LS244 integrated package for use, J11 is in parallel with J13, the outfan J9 of three-state driver is through diode CR1 circuit input end taking alarm, this warning circuit is selected 5202 Music Clips for use, and its outfan is connected to switch triode and speaker.The outfan J7 of three-state driver is connected to light emitting diode CR3 as the high temperature alarm lamp through resistance R 8, surpasses 40 ℃ as if water temperature, then sound and light alarm.The outfan J18 of three-state driver electrically connects through the resistance R 9 and the bidirectional triode thyristor SCR control utmost point.By the break-make of the triggering signal control bidirectional triode thyristor of J18 output, the outfan J16 of three-state driver is connected to light emitting diode CR2 through resistance R 10, as the display lamp of heating.One termination power live wire of internal heated type electric heated pipe, another termination bidirectional triode thyristor SCR anode.Remain on one gives fixed temperature to above-mentioned electronic temperature control circuit with can making water temperature stability in this utility model, but when operator's maloperation takes place, and when making water temperature surpass 40 ℃, this circuit is sound and light alarm and turn-off heating power supply and stop heating immediately.Therefore safe and reliable.
