Description

本实用新型是一种医院对病人输氧时所使用的氧气保温湿化装置。 The present invention is a hospital oxygen insulation is used when the patient oxygen humidification means.

目前医院里普遍采用的氧气湿化过程是将氧气输入湿化瓶,经湿化瓶中的湿化液湿化后再输送给使用的病人。 Currently oxygen humidification process commonly used hospital oxygen supply is wet bottle, delivered to the patient through the use of wet fluid bottle wet after wetting. 由于湿化瓶中的湿化液为冷水,不能产生足够的水蒸汽与氧气混合,因而不能达到湿化的目的,往往使输氧病人的呼吸道粘膜干燥、排痰困难、呼吸道不通畅。 Since wet wet fluid bottle cold water, does not produce enough water vapor is mixed with oxygen, and thus can not reach the humidification object, tend to make the patient's respiratory tract dried oxygen, expectoration difficulties, not airway patency. 另外,这种经过冷水湿化的氧气往往由于温度过低而使病人感到不适或产生其它不利的影响。 Further, the humidified oxygen through the cold water temperature is too low because patients often feel the discomfort or produce other adverse effects. 为此,有的医院定时更换热水,这不但增加了护理工作的强度,而且输出的氧气温度与湿度均不恒定,另外,当瓶中相对外界温度较高时,其氧气输出管的长度只能在50cm左右,否则湿化后的氧气在经过氧气输出管时会由于冷却而在管中产生积水,这样就限制了使用范围,而且不能满足医院中的实际使用要求。 For this reason, some hospitals regular replacement of hot water, which not only increases the strength of care, and the output of the oxygen temperature and humidity are not constant, Further, when the bottle is relatively high ambient temperatures, the length of which only the oxygen delivery pipe It can otherwise be wet after oxygen generated around 50cm while passing an oxygen outlet pipe in the pipe due to the cooling water, thus limiting the range of use, and can not meet the actual requirements of hospitals.

图1是该实施例的结构示意图;图2是该实施例的温度控制装置电路图。 FIG 1 is a schematic diagram of the embodiment; FIG. 2 is a circuit diagram of the apparatus of this embodiment the temperature control.

参见图1,该氧气保温湿化装置具有一个透明的玻璃湿化瓶1,在该湿化瓶中装有湿化液,湿化液为生理盐水或蒸溜水,在湿化瓶的瓶盖2上装有氧气输入管3和氧气输出管4,氧气输入管必须插入湿化液中,以利于氧气在湿化液中湿化,氧气输出管4应处在湿化液以上,其长度为1.5米,在距氧气输出管端头150~200mm处安装有一个可以排放积水的莫非氏管13,在瓶盖2上还设有一个加水螺塞5。 Referring to Figure 1, the oxygen humidification means holding a transparent glass having a wet bottle 1, the bottle containing wet wet fluid, wet slip was physiological saline water or steam in the wet bottle cap 2 3 on which the oxygen inlet tube and the outlet tube 4 oxygen, oxygen inlet tube must be inserted wet mixture, humidified oxygen in order to facilitate wetting liquid oxygen delivery pipe 4 should be in the above wet fluid, a length of 1.5 m , water can be discharged is mounted to a venturi 13 does, the cap 2 is further provided in a plug 5 with water at the output from the oxygen pipe end 150 ~ 200mm. 温度控制装置由插在湿化瓶1中的电加热棒6、温度探头7和温度控制盒8组成,电加热棒6的电源输入与温度控制盒8的输出相接,温度控制盒8上设有电源插头9、开关10、湿化瓶温度调节旋钮11和温度刻度盘12。 Temperature control means electrically inserted in the bottle 1 humidification heating rods 6, 7 and a temperature probe 8 consisting of a temperature control box, power input output electric heating rods 6 and the temperature of contact with the control box 8, a temperature control box 8 is provided on the a power supply plug 9, the switch 10, wet bottle 11 and the temperature of the temperature adjusting dial knob 12.

图2是本实用新型温度控制装置的电路图。 FIG 2 is a circuit diagram of the present invention, the temperature control device. 由电源插头输入的220V交流电经变压器B降至15伏,再经硅桥Z整流、电容器C1、C2滤波、稳压集成块IC1稳压后,得到一个稳压直流电源,加给由电阻R1、R2、R3、电位器W、热敏电阻Rt组成的电桥,该电桥的输出端与一个运算放大器A的输入端相接,运算放大器A的输出端连接一个三极管T的基极,该三极管T与一个继电器J一起串联在稳压后的主回路中。 Input by the 220V AC power plug B to 15 volts by the transformer, then rectified by the silicon bridge Z, capacitors C1, C2 filter, regulator IC1 regulator blocks obtained after a regulated DC power supply, applied to the resistor R1, bridge R2, R3, a potentiometer W, consisting of a thermistor Rt, the output terminal of the bridge and the input terminal of the operational amplifier a is connected, the output terminal of the operational amplifier a is connected to the base of a transistor T, the transistor in the main loop, T series regulator together with a relay J. 构成电加热棒的加热元件Rw与220V交流电相接,继电器J的一个常闭触点J与电加热棒串联。 Electric heating rods constituting the heating element and Rw phase 220V AC, the relay J, J a normally closed contact connected in series with the electric heating rods.

使用时先用湿化瓶温度调节旋钮11调整电位器W,使其处于所需的位置,然后接通电源,电加热棒6开始对湿化瓶加热。 When it is used to adjust the temperature of the wet bottle potentiometer adjustment knob 11 W, it is in the desired position, and then power, electrically heated heating rods 6 starts wet bottle. 由于构成温度探头7的热敏电阻Rt为负温度系数,当湿化瓶温度低于或等于调整的温度时,热敏电阻Rt大于或等于使电桥平衡所需要的阻值,即当R1=R3时,Rt≥W-R2,电桥失去平衡或平衡,运算放大器的负向输入电压大于或等于正向输入电压,运算放大器输出低电位,三极管T不导通,继电器J不工作,电加热棒正常加热。 Since the temperature probe constituting the thermistor Rt. 7 is a negative temperature coefficient, when the temperature of the wet temperature of less than or equal to the bottles adjustment, thermistor Rt equal to or greater than the electrical resistance of the bridge balance required, i.e., when R1 = when R3, Rt≥W-R2, the bridge out of balance or equilibrium, the operational amplifier to the negative input voltage is greater than or equal to a positive input voltage, the operational amplifier outputs a low potential, the transistor T does not conduct, the relay J does not work, electrically heated normal heating rod. 反之,当湿化瓶温度大于调整温度时,热敏电阻Rt小于使电桥平衡所需要的阻值,电桥失去平衡,运算放大器A的正向输入电压大于反向输入电压,其输出高电位,三极管T导通,继电器J工作,常闭触点J断开,电加热棒6停止加热。 Conversely, when the temperature is greater than wet bottle adjust the temperature, thermistor Rt is smaller than the electrical resistance value required for bridge balance, the bridge out of balance, the positive input of the operational amplifier A is greater than the negative input voltage, which outputs the high potential , the transistor T is turned on, work relay J, J normally closed contacts open, electrically heated heating rods 6 is stopped. 这样就达到了保温湿化氧气的目的。 This will achieve the purpose of holding wet oxygen.

由于湿化瓶中的温度较高,湿化后的氧气在经过较长的氧气输出管时会由于冷却而产生积水,此时可打开莫非氏管的排放管排出积水,以保证氧气输出管中的积水不会被病人吸入。 Because of the higher temperature of the wet bottle, oxygen humidification after the cooling due to water generated during oxygen delivery pipe over a long, open at this time does the discharge pipe's water discharge pipe, to ensure that oxygen output water pipes will not be drawn into the patient.
