Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for controlling a ventilator according to the present invention. As shown in fig. 1, the method for controlling shutdown of a ventilator according to the embodiment of the present invention includes the following steps:
and S100, when the breathing machine is in an operating state, if a shutdown operation instruction is detected, judging whether the current oxygen concentration is within a preset threshold range.
Specifically, the airflow channels in a ventilator are: the air inlet tower (air inlet), the air channel (metal device), the blower, the flow monitoring device, the current oxygen concentration detection device, the humidifying tank, the oxygen shut-off valve is arranged between the air inlet and the air channel, and is controlled by the controller. The invention increases the oxygen concentration detection flow in the shutdown process. When the breathing machine is running, if an operator wants to close the breathing machine, the shutdown key is pressed, the breathing machine detects a shutdown operation instruction, and whether the current oxygen concentration is within a preset threshold range is judged first, so that the breathing machine cannot be directly shut down. Therefore, the problem that the operation staff does not shut down according to the normal sequence, namely the breathing machine is closed without closing the oxygen supply valve, so that oxygen leaks or high-concentration oxygen stays in the air inlet of the breathing machine, and potential safety hazards are further caused is avoided.
In another implementation, the shutdown operation instruction may also be a pause operation instruction. That is, the present invention also increases the oxygen concentration detection flow during the suspension. When the ventilator is running, if an operator wants to pause the ventilator, the pause key is pressed, and the ventilator detects the pause operation instruction, and whether the current oxygen concentration is within the preset threshold range is also judged first, so that the ventilator cannot be directly paused. Therefore, the problem that the operator pauses not according to the normal sequence, namely, the respirator is paused without closing the oxygen supply valve, so that the oxygen leaks or high-concentration oxygen stays in the air inlet of the respirator, and potential safety hazards are further caused is avoided.
In one implementation, the preset threshold range is greater than or equal to 25%. That is, when the ventilator is in an operating state, if a shutdown operation instruction is detected, it is determined whether the current oxygen concentration is greater than or equal to 25%.
In one implementation, referring to fig. 2, the step S100 specifically includes:
s110, when the breathing machine is in an operating state, if a shutdown operation instruction is detected, automatically detecting the current oxygen concentration;
s120, judging whether the current oxygen concentration is within a preset threshold range.
Specifically, an oxygen concentration detection device is arranged on the breathing machine and can automatically detect the oxygen concentration of the breathing machine, and when an operator presses a shutdown key or a pause key, the controller indicates the oxygen concentration detection device to automatically detect the current oxygen concentration so as to judge whether the current oxygen concentration is in a preset threshold range or not.
The step S100 is followed by: and S200a, if the current oxygen concentration is within the preset threshold range, not executing shutdown operation.
That is, if the current oxygen concentration is greater than or equal to 25%, the shutdown operation is not performed. That is, when the current oxygen concentration is greater than or equal to 25%, it is indicated that the oxygen supply valve is not closed at this time, that is, an operator has an operation error, and does not close the oxygen supply valve first and then presses the shutdown key. In order to avoid potential safety hazards, the invention refuses to execute the shutdown operation instruction, namely, shutdown is not allowed under the condition that the current oxygen concentration is greater than or equal to 25 percent.
In one implementation, the step S200 specifically includes: if the current oxygen concentration is within the preset threshold range, popping up an oxygen non-closing prompt, and not executing the shutdown operation.
That is, when the invention does not execute the closing operation, the invention gives an oxygen non-closing prompt so that an operator can know the operation error in time, and the oxygen supply valve needs to be closed first and then the shutdown key or the pause key is pressed down, thereby being very convenient.
In a further implementation, referring to fig. 3, the step S200a further includes:
s310a, when a shutdown operation instruction is detected again, continuing to judge whether the current oxygen concentration is within a preset threshold range;
and S320a, if the current oxygen concentration is not within the preset threshold range, executing shutdown operation.
That is, when the ventilator refuses to execute the shutdown operation instruction, the ventilator is not shutdown, and the operator knows that the error is caused at this time, and the oxygen supply valve is closed. Then, the user is required to press the shutdown key again, the controller instructs the oxygen concentration detection device to automatically detect the current oxygen concentration, and since the oxygen supply valve is closed by the operator under the prompt, the current oxygen concentration is less than 25%, at this time, shutdown operation can be performed, and then the cooling mode is entered or the direct shutdown is performed.
Similarly, when the ventilator refuses to execute the pause operation instruction, the ventilator is not paused, and the operator knows that the error is caused, and the oxygen supply valve is closed. Then, the user is required to press the pause key again, the controller instructs the oxygen concentration detection means to automatically detect the current oxygen concentration, and since the operator has closed the oxygen supply valve under prompt, the current oxygen concentration is less than 25%, at which time a pause operation can be performed, and then the pause mode is entered.
In a second implementation manner, the step S200a further includes: and waiting for an operator to perform the operation of confirming that the oxygen is closed, and executing the shutdown operation when receiving an instruction of confirming that the oxygen is closed by the operator.
That is, when the ventilator refuses to execute the shutdown operation instruction, the ventilator is not shutdown, and the operator knows that the error is caused at this time, and the oxygen supply valve is closed. Then, the user does not need to press the shutdown key any more, but pops up a prompt for confirming that the oxygen is closed, and an operator can confirm that the oxygen is closed after closing the oxygen supply valve. At the moment, the breathing machine can execute shutdown operation, then enters a cooling mode or is directly shut down, so that the operation of shutting down again is omitted, and the breathing machine is more convenient.
Similarly, when the ventilator refuses to execute the pause operation instruction, the ventilator is not paused, and the operator knows that the error is caused, and the oxygen supply valve is closed. Then, the user does not need to press the pause key any more, but pops up a prompt for confirming that the oxygen is closed, and an operator can confirm that the oxygen is closed after closing the oxygen supply valve. At this time, the ventilator may perform a pause operation and then enter a pause mode.
In a third implementation manner, the step S200a further includes: and controlling the oxygen supply valve to be automatically closed, and executing shutdown operation after the oxygen supply valve is closed.
That is, the invention can also automatically close the oxygen supply valve without manual operation of operators, thereby improving the convenience of operation.
In one implementation, the step S100 further includes: and 200b, if the current oxygen concentration is not within the preset threshold range, executing shutdown operation. That is, if the current oxygen concentration is less than 25%, it indicates that the operator has closed the oxygen supply valve, and at this time, the shutdown operation may be directly performed.
In a further implementation manner, referring to fig. 4, the step S200b specifically includes:
s210b, if the current oxygen concentration is not within the preset threshold range, popping up whether to confirm closing of the inquiry prompt;
and S220b, if a confirmation closing operation instruction which is made to the confirmation closing inquiry prompt is received, executing a closing operation.
In order to prevent an operator from misoperation of a shutdown key and a pause key, when executing a shutdown instruction or a pause instruction, firstly popping up a confirmation shutdown inquiry prompt so as to ensure that the operator confirms whether shutdown is required or not, and executing shutdown after the confirmation of a user.
In a further implementation manner, the step S210b further includes: and if a non-closing operation instruction which is made to the confirmation closing inquiry prompt is received, not executing the closing operation. That is, if the operator does not confirm the shutdown, it is indicated that the operator has erroneously operated the shutdown key, and the shutdown operation is not performed.
Further, as shown in fig. 5, based on the above-mentioned method for controlling shutdown of a ventilator, the present invention further provides a ventilator, which includes a processor 10 and a memory 20. Fig. 5 shows only a portion of the components of the ventilator, but it should be understood that not all of the illustrated components need be implemented, and that more or fewer components may alternatively be implemented.

The memory 20 may in other embodiments also be an external storage device of the ventilator, such as a plug-in hard disk, smart Media Card (SMC), secure Digital (SD) Card, flash Card (Flash Card) or the like, which are provided on the ventilator. Further, the memory 20 may also include both an internal storage unit and an external storage device of the ventilator. The memory 20 is used for storing application software installed on the ventilator and various data, such as program codes for installing the ventilator. The memory 20 may also be used to temporarily store data that has been output or is to be output.
