Embodiment 1

[0037]The present invention provides a heating tube temperature control system for respiratory support equipment, comprising: a controller 1, a turbine 2, an ambient temperature sensor 3, a pipeline temperature sensor 4, a heating tube 5, a heating driver 6 and a power supply 7; the turbine 2, The ambient temperature sensor 3, the pipeline temperature sensor 4 and the heating driver 6 are respectively connected to the controller 1; the power supply 7 is respectively the controller 1, the turbine 2, and the heating driver 6 power supply; the heating tube 5 has a heating wire, and the heating wire is connected to the heating driver 6; the pipeline temperature sensor 4 is installed at the end of the heating tube 5; the controller 1 includes a device The setting unit is used to set the temperature value of the snorting demand and the airflow velocity value of the turbine 2 outlet. Specifically, the controller 1 is a processor (MCU (Microcontroller Unit, micro control unit) or CPU ...

Embodiment 2

[0059] Set the snorting demand temperature value to 33°C, the airflow velocity value to 40L / Min, and the supplementary temperature table is the following table:

[0060]

[0061]

[0062] When the machine is turned on for treatment, it first detects the current ambient temperature value, and the controller 1 obtains the temperature compensation value Z°C of the nasal oxygen tube part according to the above table, and the ambient temperature value is also collected and monitored in real time. Afterwards, the temperature at the end of the pipeline is detected in real time, and the control accuracy k is set to 2, and the total number of data a of the pipeline temperature threshold group is set to 5, and judgment is made based on this: 1. When the When the end temperature of the pipeline temperature value is less than (33+Z-1) ° C, the heating tube 5 is heated rapidly with a heating power value of 92% as the operating power; 2. When the pipeline temperature value is less than...

Embodiment 3

[0064] A respiratory support device, comprising the temperature control system of the heating tube of the respiratory support device.

[0065] The respiratory support equipment is mainly composed of the main body of the humidification oxygen therapy instrument, a humidification water box, a heating plate and an external pipeline. The water box and the heating plate constitute the main structure of the humidification part, and the external pipeline is mainly a heating pipeline and a nasal oxygen tube. composition.

[0066]After the air and oxygen are mixed, they enter the water box after passing through the turbine 2, and the heating plate continues to heat, taking away part of the water vapor, and then supplying the patient after being heated and kept warm by the heating pipeline. This invention mainly introduces the method of controlling the heating temperature of the heating pipeline through empirical data and monitoring the temperature at the end of the pipeline and the amb...

Abstract

The present invention relates to a heating pipe temperature control system and method for a respiratory support device and a respiratory support device. The heating pipe temperature control system forthe respiratory support device comprises a controller, a turbine, an ambient temperature sensor, a pipeline temperature sensor, a heating pipe, a heating driver and a power supply; the turbine, the ambient temperature sensor, the pipeline temperature sensor and the heating driver are respectively connected with the controller; the power supply respectively supplies power to the controller, the turbine and the heating driver; the heating pipe is provided with a heating wire and the heating wire is connected with the heating driver; the pipeline temperature sensor is arranged at a tail end of the heating pipe; and the controller comprises a setting unit. Through real-time feedback of temperatures at the tail end of the heating pipeline and the ambient temperatures, temperature control powerof the whole heating pipeline is controlled and adjusted, and warmth and moistness of final airflow blown out from a tail end of a nasal oxygen cannula are ensured.

Description

technical field [0001] The invention relates to the field of respiratory support equipment control, in particular to a temperature control system and method for a heating tube of the respiratory support equipment and the respiratory support equipment. Background technique [0002] Respiratory support technology is an important means of treating respiratory failure. Nasal high-flow oxygen humidification therapy (referred to as high-flow oxygen therapy, High-Flow Nasal Cannula, HFNC) is a new type of respiratory support technology. The warmed and humidified gas, with a flow rate of 30-60L / Min or above, achieves the purpose of delivering a stable concentration of oxygen, flushing the dead space of the upper airway, and generating a certain positive end-expiratory airway pressure, and the patient's tolerance is good . [0003] The current high-flow oxygen therapy products are mainly medical products. For some patients with mild symptoms, hospitalization will generate high costs...
