Heating device for gas humidifier

Abstract

The invention discloses a heating device for a gas humidifier. The heating device comprises a casing, a heating disc assembly and a center control module. The heating disc assembly is provided with a heating disc and is installed on the casing, and the heating disc is exposed above the casing. The center control module comprises a power source assembly, a human-computer interface and a main control circuit board assembly, wherein the power source assembly and the main control circuit board assembly are fixedly installed on the casing and accommodated in the casing, and the human-computer interface is installed on the casing and exposed on the side of the casing. The human-computer interface is electrically connected with the power source assembly and the main control circuit board assembly and operates the center control module by controlling and sending data. By optimal design of the casing, danger of burning and scalding and faults such as open circuit are effectively avoided, and danger of electric leakage and electric shock can be effectively avoided by optimal design of the heating disc assembly. By optimal design of the center control module, a whole humidifying system is high in intelligence degree, safe and reliable.

Description

technical field [0001] The invention relates to the technology in the field of gas humidifiers, in particular to a heating device for a gas humidifier. Background technique [0002] Several methods are known in the prior art to supply humidified warmed gas to a patient in order to assist the patient's breathing. The heating device of the existing gas humidifier adopts a built-in type. For example, a heating rod or a heating block is connected to the humidification bottle to directly heat the water in the humidification bottle. This method is difficult to control the water temperature, and the heating time is too long. It is difficult to control. There are also some heating devices installed under the humidifying bottle on the market, but the heating device is very simple and easy to burn out, and there have been dangers such as leakage contacts and burns. This type of heating device only has a simple heating function. Without any other function, the temperature control is r...

The heating device of the existing gas humidifier adopts a built-in type. For example, a heating rod or a heating block is connected to the humidification bottle to directly heat the water in the humidification bottle. This method is difficult to control the water temperature, and the heating time is too long. It is difficult to control. There are also some heating devices installed under the humidifying bottle on the market, but the heating device is very simple and easy to burn out, and there have been dangers such as leakage contacts and burns. This type of heating device only has a simple heating function. There is no other effect, and the control of temperature is relatively inaccurate, with large fluctuations, and it is impossible to know the operation of the entire gas humidifier, just simple heating

The existing heating methods are too simple and have low safety factors, poor performance, and few functions, which can no longer meet people's increasingly high requirements for medical equipment in terms of safety performance and intelligence.
