Constant-temperature humidification device

Abstract

The invention relates to a constant-temperature humidification device, comprising: a gas source inlet disposed at the middle and lower part of one side of the device; a gas source outlet at the middleand upper part of the other side of the device; a thermostat disposed at the bottom of the device; a power supply connection line connected to the thermostat and penetrating the device. The device isadvantageous in that the thermostat performs mild heating and thermal insulation for the device to avoid a sharp rise in temperature; a baffle structure with a unique structure is arranged in the humidification device, can prolong the residence time of gas in the device, and can avoid humidity or temperature loss of heated and humidified gas in a flowing process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a constant temperature humidification device. Background technique [0002] During some treatments, it is necessary to warm and humidify the gas delivered to the patient in order to assist the patient to breathe. [0003] Existing gas humidification devices usually use built-in heating. For example, a heating rod is installed in the humidification bottle to directly heat the liquid (such as water) in the humidification bottle. However, this method cannot effectively control the water temperature and is prone to sudden temperature changes. There is a problem of rising, and there are certain safety hazards (such as circuit short circuit). [0004] In addition, there is also a heating device installed at the bottom of the humidification bottle to heat the humidification bottle, but this kind of heating device has a simple structure and is prone to damage, electric leakage, ...

Problems solved by technology

[0003] Existing gas humidification devices usually use built-in heating. For example, a heating rod is installed in the humidification bottle to directly heat the liquid (such as water) in the humidification bottle. However, this method cannot effectively control the water temperature and is prone to sudden temperature changes. Rising problem, and there are certain safety hazards (such as circuit short circuit)

[0004] In addition, there is also a heating device installed at the bottom of the humidification bottle to heat the humidification bottle. However, this heating device has a simple structure and is prone to damage, electric leakage, electric shock or burns and other safety hazards, and it is also impossible to control the temperature.
