The utility model discloses an oxygen thermal insulation damp device used for a hospital to supply oxygen for patients, which is composed of a damp bottle, an oxygen input pipe, an oxygen outlet pipe, a Murphy's dropper which is arranged at the oxygen output pipe, and a temperature control device which is arranged at the damp bottle. The utility model solves the defects existing in the prior art that the performance of the damp oxygen is not good, the length of the oxygen output pipe is shorter and the use is complicated. The oxygen humidity and temperature which are outputted through the utility model are constant and can be adjusted according to requirements, and the practical using requirements of the hospital can be satisfied fully.

Description

Oxygen thermal insulation damp device

This utility model is a kind of hospital employed oxygen insulation humidification device when patient is cured by oxygen therapy.

The oxygen humidification process that generally adopts in the hospital is that oxygen is imported humidification bottle at present, flows to the patient of use after the humidification fluid humidifying in humidification bottle again.Because the humidification fluid in the humidification bottle is a cold water, can not produce enough water vapour and oxygen mix, thereby can not reach the purpose of humidifying, often make oxygen therapy patient's respiratory mucosa drying, expectoration difficulty, respiratory tract obstructed.In addition, this oxygen through the subcooled water humidifying is often crossed the low patient of making and is not felt well or produce other adverse influence owing to temperature.For this reason, the hospital that has regularly changes hot water, this has not only increased the intensity of nursery work, and the oxygen temperature and the humidity of output are all non-constant, in addition, and when ambient temperature is higher relatively in the bottle, the length of its oxygen output tube can only be about 50cm, otherwise the oxygen after the humidifying can produce hydrops owing to cool off in pipe through oxygen output tube the time, so just limited the scope of application, and can not satisfy the actual instructions for use in the hospital.

The purpose of this utility model is to overcome above-mentioned existing in prior technology weak point and a kind of oxygen insulation humidification device is provided.

Technical solution of the present utility model is: a kind of oxygen insulation humidification device, comprise humidification bottle, oxygen input tube, oxygen output tube, its special character is, the Mo Feishi pipe that can discharge hydrops is installed on the described oxygen output tube, a temperature control equipment is installed on the described humidification bottle.

Mo Feishi pipe in the above-mentioned technical solution can be mounted in apart from 15～20cm place, oxygen output tube termination.

The audion that the electric bridge that temperature control equipment in the above-mentioned technical solution can comprise regulated power supply, be made up of resistance, critesistor, potentiometer, the operational amplifier that joins with the electric bridge outfan, base stage and operational amplifier output terminal join, the electric heater that joins with the placed in-line relay of this audion, with alternating current power supply and the relay normally-closed contact that is connected in series with electric heater.

Temperature control equipment of the present utility model can adopt various known temperature control device, but should be with simple in structure and cost is less is advisable.

Accompanying drawing has been described a preferred embodiment of the present utility model.

Fig. 1 is the structural representation of this embodiment;

Fig. 2 is the temperature control equipment circuit diagram of this embodiment.

Referring to Fig. 1, this oxygen insulation humidification device has a transparent glass humidification bottle 1, in this humidification bottle, humidification fluid is housed, humidification fluid is normal saline or aquae destillata, oxygen input tube 3 and oxygen output tube 4 are housed on the bottle cap 2 of humidification bottle, oxygen input tube must insert in the humidification fluid, be beneficial to oxygen humidifying in humidification fluid, oxygen output tube 4 should be in more than the humidification fluid, its length is 1.5 meters, at 150～200mm place, distance oxygen output tube termination a Mo Feishi pipe 13 that can discharge hydrops is installed, on bottle cap 2, also is provided with one and adds Chiragra Spider Conch plug 5.Temperature control equipment is made up of the electrically heated rod 6, temperature probe 7 and the temperature control box 8 that are inserted in the humidification bottle 1, the power supply input and the output of temperature control box 8 of electrically heated rod 6 are joined, and temperature control box 8 is provided with attaching plug 9, switch 10, humidification bottle temperature adjustment knob 11 and temperature scale dish 12.

Fig. 2 is the circuit diagram of this utility model temperature control equipment.220V alternating current by the attaching plug input is reduced to 15 volts through transformator B, again after silicon bridge Z rectification, capacitor C1, C2 filtering, integrated package of pressure-stabilizing IC1 voltage stabilizing, obtain a constant voltage dc source, add to the electric bridge of forming by resistance R 1, R2, R3, potentiometer W, critesistor Rt, the input of the outfan of this electric bridge and an operational amplifier A joins, the outfan of operational amplifier A connects the base stage of an audion T, in the major loop of this audion T after a relay J is connected on voltage stabilizing.The heating element heater Rw and the 220V alternating current that constitute electrically heated rod join, and a normally-closed contact J of relay J connects with electrically heated rod.

Earlier adjust potentiometer W during use, make it be in the desired position with humidification bottle temperature adjustment knob 11, energized then, electrically heated rod 6 begins humidification bottle is heated.Because constituting the critesistor Rt of temperature probe 7 is negative temperature coefficient, when the humidification bottle temperature is less than or equal to the temperature of adjustment, critesistor Rt is more than or equal to making the needed resistance of bridge balance, promptly when R1=R3, and Rt 〉=W-R2, electric bridge disequilibrium or balance, the negative sense input voltage of operational amplifier is more than or equal to the forward input voltage, and operational amplifier is exported electronegative potential, not conducting of audion T, relay J is not worked, the electrically heated rod normal heating.Otherwise, when the humidification bottle temperature when adjusting temperature, critesistor Rt is less than making the needed resistance of bridge balance, electric bridge disequilibrium, the forward input voltage of operational amplifier A are greater than reverse input voltage, and it exports high potential, audion T conducting, relay J work, normally-closed contact J disconnects, and electrically heated rod 6 stops heating.So just reached the purpose of insulation humidify oxygen gas.

Because the temperature in the humidification bottle is higher, the oxygen after the humidifying can be opened the delivery pipe discharge hydrops of Mo Feishi pipe this moment because cooling produce hydrops through long oxygen output tube the time, can not sucked by patient with the hydrops in the assurance oxygen output tube.
