Breathing long tube heating device having automatic temperature control function

Abstract

The invention discloses a breathing long tube heating device having an automatic temperature control function. The breathing long tube heating device having the automatic temperature control function comprises a temperature controller, a heating wire used for being placed in a long tube and a connector arranged at one end of the heating wire, wherein a part of the heating wire is provided with heating strips connected with the temperature controller, the other part of the heating wire is not provided with heating strips, two temperature sensors connected with the temperature controller are arranged on the heating wire and comprises a first temperature sensor and a second temperature sensor, the first temperature sensor is arranged at the part, provided with the heating wires, of the heating wire or is close to the heating strips, and can measure the temperature of the heating strips, and the second temperature sensor is arranged at the part, not provided with the heating wires, of the heating wire. The breathing long tube heating device having the automatic temperature control function can control the temperature rise of the heating strips in time according to the room temperature and the temperature of gas output by the long tube in order to heat the gas, can control temperature drop of the heating strips in time according to the temperature of the heating strips, prevents the long tube from being burned out due to the fact that the heating wire is overheated, and well achieves the purposes of improving the heating temperature of the gas and avoiding the situation that the long tube is burned out due to too high temperature.

Description

technical field [0001] The invention belongs to breathing equipment, in particular to an automatic temperature-controlled breathing long tube heating device. Background technique [0002] The long breathing tube in the non-invasive ventilator is used to connect the breathing mask and the ventilator host, and is the gas circulation channel of the ventilator. Due to the long length of the long breathing tube and the poor insulation effect, when the heated and humidified gas of the ventilator is transported from the long breathing tube to the mask end, the temperature and humidity of the gas are greatly reduced, so that it cannot satisfy the patient's breathing comfort. It is more likely to condense into water dew, causing discomfort to the patient's face. [0003] At present, most of the heating and humidifying devices widely used are heating and humidifying devices placed inside the ventilator. Such devices often make the gas flowing out of the ventilator have a certain tem...
