specific Embodiment 1
[0031] The present invention provides a kind of high-availability infant breathing equipment, and described equipment comprises the following modules:
[0032] The checkpoint module is used to save the state information of the specified process to the non-volatile storage medium when the preset condition is met, and record the time when the state information of the process is saved;
[0033] Checkpoint technology is to save the relevant information of the process at an appropriate moment. When the process needs to be restored, use the saved process-related information to restore the process to the corresponding state, such as saving the code segment, data segment, stack, etc. of the process.
[0034] The watchdog module is used to send a restart signal to the microprocessor of the infant respiratory equipment if it does not receive the dog feeding signal from the system within the preset time, and record the time of sending the restart signal; when the infant respiratory equipm...
specific Embodiment 2
[0060] The present invention also provides a high-availability infant respiratory system, which includes a power supply, a heated humidifier, an air hose, and the device described in Embodiment 1. In one embodiment, such as image 3 As shown, the breathing apparatus for infants includes a memory 31, a display 32, a microprocessor 33, an input device 34, and a watchdog 35, and a power supply, a heated humidifier, and an air hose are not shown.
specific Embodiment 3
[0062] Such as Figure 4 As shown, the present invention also provides a highly available respiratory system for infants and young children, the system includes a server 42 and the device 41 as described in Embodiment 1; the device and the server transmit data through a network. In one embodiment, the shown system further includes a mobile terminal, and the infant respiratory system establishes a connection with the server through the mobile terminal.

Abstract
The invention provides high-availability infant breathing equipment and system. The high-availability infant breathing equipment specifically comprises a check point module used for storing state information of a specified process into a nonvolatile storage medium when a preset condition is met and recording the storage time of the state information of the process; a watchdog module, which is used for sending a restart signal to a microprocessor of the infant breathing equipment if a dog feeding signal sent by the system is not received within preset time, recording the time for sending the restart signal, and within a preset time after the infant breathing equipment is restarted, sending the time for sending the restart signal within a period of time stored by the watchdog module to the microprocessor; and a state recovery module, which is used for determining state information used for recovering the specified process in the infant breathing equipment according to the time for sending the restart signal in the period of time. According to the invention, the problem that a watchdog restarts the breathing machine repeatedly due to the fact that the process state generated by the check point is recovered and then the process state falls into a fault again is avoided, and the reliability of the infant breathing equipment is improved.
Description
technical field [0001] This application relates to the field of medical devices, in particular to respiratory equipment for infants. Background technique [0002] The ventilator is a commonly used clinical equipment, which can give patients respiratory support, improve the patient's breathing, and play an important role in maintaining the patient's breathing. As a commonly used device in the respiratory emergency department, there are two types of ventilators: non-invasive ventilator and invasive ventilator. Since non-invasive ventilator does not cause trauma to patients, non-invasive ventilator is often used in normal assisted breathing. During use, due to unstable power supply, magnetic field interference, etc., the embedded ventilator will cause the program to run away or deadlock, which will cause the system to be stuck. For the program to run away, endless loop or system to be stuck, the watchdog is often used. The so-called watchdog means that the watchdog is set in t...
