Description

Heating humidifier

Technical Field

The utility model relates to the technical field of medical equipment accessories, especially a humidifier heats.

Background

In clinical treatment in the respiratory department, a breathing machine is a common medical instrument. Because the air from the breathing machine is dry and cold, if a human body directly inhales the dry and cold air, the respiratory tract is dehydrated, the mucous membrane is dry, the ciliary movement is inhibited or lost, the secretion becomes sticky to form sputum scab, the unsmooth sputum discharge can be caused, and the secondary infection of the trachea blockage can be caused. Therefore, the gas from the ventilator needs to be heated and humidified. The traditional heating humidifier comprises a hollow shell, medical distilled water is contained in the shell, a heating device is arranged inside or at the bottom of the shell, an air inlet pipe and an air outlet pipe are arranged at the upper part of the shell, and the air inlet pipe and the air outlet pipe are both suspended above the liquid level. The air from the respirator enters the shell through an air inlet pipe, is mixed and humidified with the water vapor generated after heating, and is discharged through an air outlet pipe, namely, a vapor humidifying method.

This method of warming and humidifying has many drawbacks:

1. the output of the humidification system is not well controlled (the output water vapor content in unit time is mg/l): the method mainly comprises the steps that water in the water tank is evaporated to generate water vapor by heating the water tank through the heating plate, and the evaporation amount depends on a plurality of factors such as the temperature of the heating bottom plate, the contact area of the heating bottom plate and the water tank, the heat conducting property of the material of the water tank and the like;

2. insufficient control precision and long response time: because the evaporation capacity is determined by the water temperature and the pressure in the tank body, the evaporation capacity is large when the water temperature is high, and the evaporation capacity is small when the water temperature is low. The temperature of water is conducted to the water tank by the heating bottom plate and then conducted to the water by the water tank, a large amount of loss is caused in the heat conduction process, and the heat conduction response time is long, so that the temperature and the humidity are not easy to control accurately and in real time.

3. The condensed water in the pipeline is serious: due to the steam heating mechanism, the gas is in a supersaturated state at the outlet of the water tank. If the pipeline is a common pipeline, the temperature of the obtained gas reaching the human body is 37 ℃, the gas needs to reach higher temperature at the outlet of the water tank, and a large amount of condensed water is generated in the process of reducing the temperature of the gas from higher temperature to 37 ℃ in the pipeline, so that the safety of a patient is influenced. If the heating pipeline is matched, although the generation of condensed water can be reduced, the essence of the condensed water separated out when the gas is changed from supersaturation to saturation state in the moving process of the pipeline is not changed.

4. The equipment is too big, and too heavy is unfavorable for placing the transport, increases the doctor and operates the degree of difficulty.
