2. need special adjusting and control device to control temperature and humidity, increase the cost of equipment unavoidably.
3. water container and patient are approaching, cause germ contamination easily.
4. steam is in pipe conveying procedure, heat is lost in a large number, pipeline internal-external temperature difference great disparity, steam condenses and accumulates, this not only influences the humidifying effect, but also interference gas exchange, and the timely processing of hydrops needs Special Equipment and troublesome poeration, the humidifier of heating that has is put resistance wire in addition around gas pipeline, it is too much that steam heats power consumption once again.
5. circuit is too near apart from patient, has moistening pipeline to link to each other again, adopts 220 volts of voltage source patients dangerous.
6. need to adopt complicated element and circuit such as pick off etc., can control heating-up temperature.
7. unless add blowing device in addition, otherwise be difficult to high frequency jet ventilator.
8. can not be used for gentle humidifying of adding of general oxygen anapnotherapy.
In order to address the above problem, forefathers once proposed many improvement projects, and the invention as the US4028445 narration is divided into two water-storage pot and evaporator, utilizes simple infusion set, and the quantity of control water evaporates has overcome above-mentioned 1,2,3 shortcoming basically.But from overall structure, this utensil can not directly link to each other with patient airway, after producing, steam sucks the patient respiration road, still need one section long steam transmitting pipe, the phenomenon that the interior steam of pipe condenses into water can hardly be avoided, the water collection device of describing in this design can only be got rid of the hydrops of evaporator itself, can not solve the problem of steam transmitting pipe inner product water treatment.In addition, this heat humidifier is not mentioned temperature controlling instruments, and under the sealing situation, the temperature and pressure of steam may be too high, surpasses the scope that patient allows, and these all remain further to be solved.
