The internal circulation circuit 120 comprises an inspiration branch 121 and an expiration branch 122, one end of the inspiration branch 121 and one end of the expiration branch 122 are respectively connected to the patient 400 through a patient breathing connector 500, and the other ends of the expiration branch 122 and the inspiration branch 121 are both communicated with the breathing driving device 140; the air suction branch 121 is provided with an air suction one-way valve 1211 and a carbon dioxide absorption device 1212; the expiration branch 122 is provided with an expiration check valve 1221. The fresh gas delivery branch 130 communicates with the suction branch 121.
The respiratory drive apparatus 140 includes a bellows 141 and a folding bladder 142 disposed within the bellows 141. The driving gas branch 110 is communicated with the bellows 141, and the internal circulation circuit 120 is communicated with the folding bladder 142. In specific application, when the patient 400 inhales, the breathing power device inputs driving gas into the bellows 141, compresses the folding bag 142, pushes the gas stored in the folding bag 142 to be discharged to the inspiration branch 121, absorbs carbon dioxide through the carbon dioxide absorption device 1212, and then joins with the fresh gas delivered by the fresh gas delivery branch 130 and delivers the fresh gas to the patient 400; when the patient 400 exhales, the gas exhaled by the patient 400 is delivered into the folded bladder 142 through the exhalation check valve 1221, and the folded bladder 142 is lifted up. Of course, in certain applications, the respiratory drive apparatus 140 may alternatively be a manual bladder (not shown), with the internal circulation circuit 120 being in communication with the manual bladder; alternatively, the respiratory drive apparatus 300 may also include both a combination of bellows 310 and collapsible bladder 320 and a manual bladder, both of which may be selectively communicated with the internal circulation circuit through a directional valve to switch between the motorized and manual modes of ventilation.
The power supply 200 is used to power the turbine 111. The temperature monitoring system 300 includes a temperature detecting device 310 for monitoring the temperature of the turbine 111 and a control system 320 for outputting at least two different processing measures based on different temperature detection results fed back from the temperature detecting device 310. In this embodiment, the control system 320 can output at least two control systems 320 with different processing measures according to different temperature detection results fed back by the temperature detection device 310, so as to implement high-temperature early warning stage processing on the turbine 111, so as to remind a worker to intervene in advance to process the temperature rise problem of the turbine 111 before the temperature of the turbine 111 does not affect the normal operation of the breathing apparatus, thereby facilitating reduction of the phenomenon that the breathing apparatus stops working due to the high temperature of the turbine 111, and finally facilitating the implementation of the long-term continuous operation of the breathing apparatus.
Preferably, in this embodiment, a first preset temperature, a second preset temperature and a third preset temperature are set in the control system 320, the first preset temperature is less than the second preset temperature, and the second preset temperature is less than the third preset temperature. When the temperature detection device 310 detects that the temperature of the turbine 111 is greater than or equal to the first preset temperature, the control system 320 controls to send out the first warning signal and controls to keep the turbine 111 to still work normally, so that the temperature rise phenomenon of the turbine 111 can be conveniently and timely reminded to intervene by a worker, and the worker can timely investigate the reason why the turbine 111 generates the high-temperature early warning on the premise that the normal work of the breathing equipment is not affected. When the temperature detection device 310 detects that the temperature of the turbine 111 is greater than or equal to a second preset temperature, the control system 320 controls to send a second warning signal and controls the turbine 111 to stop working, so that the gas circuit system 100 stops the mechanical control ventilation function, thereby being convenient for better reminding workers that the temperature of the turbine 111 is close to the maximum use temperature allowed by the design of the workers, further being capable of better warning that the high-temperature problem of the turbine 111 needs to be treated as soon as possible, and being beneficial to protecting the turbine 111. When the temperature detecting device 310 detects that the temperature of the turbine 111 is greater than or equal to the third preset temperature, the control system 320 controls the power supply 200 to be turned off, which is beneficial to protecting hardware facilities of the breathing equipment, and further fully ensures the safety and reliability of the breathing equipment.
In the preferred embodiment of this embodiment, the control system 320 is simultaneously provided with a first preset temperature, a second preset temperature and a third preset temperature, and the high temperature early warning of the turbine 111 is implemented by three-level processing measures, so that the temperature rise of the turbine 111 can be quickly raised by the staff according to different warning signals, and the safety and reliability of the breathing apparatus can be guaranteed. Specifically, the first-stage processing measure is only to send out a warning signal, and does not perform any processing on the breathing apparatus, so as to remind the worker to manually investigate the reason for the high-temperature early warning of the turbine 111 in time on the premise of not affecting the normal operation of the breathing apparatus, for example, to check whether an air conditioner is not turned on in the external environment where the lower breathing apparatus is located, or whether a device generating high temperature exists around the external environment where the lower breathing apparatus is located; the second-stage processing measure sends out a warning signal and controls the turbine 111 to stop working from software, but at the moment, the breathing equipment can still carry out manual driving ventilation work through a manual leather bag; the third level of processing is to disconnect the power supply 200 from the hardware, thereby facilitating the prevention of high temperatures that continue to burn out the hardware and cause safety hazards.
Of course, in certain applications, the high temperature warning of the turbine 111 in the control system 320 may include only two measures, for example, as an alternative embodiment: the control system 320 is provided with a first preset temperature and a second preset temperature, but not a third preset temperature, when the temperature detection device 310 detects that the temperature of the turbine 111 is greater than or equal to the first preset temperature, the control system 320 controls to send a first warning signal and keeps the turbine 111 still capable of normally working, and when the temperature detection device 310 detects that the temperature of the turbine 111 is greater than or equal to the second preset temperature, the control system 320 controls to send a second warning signal and controls the turbine 111 to stop working, so that the gas circuit system 100 stops the mechanical control ventilation function. In this alternative embodiment, the control system 320 is equivalent to only include the first and second stage treatment measures described above for the high temperature treatment of the turbine 111. Alternatively still, as another alternative embodiment: the control system 320 is internally provided with a first preset temperature and a third preset temperature, but not provided with a second preset temperature, when the temperature detection device 310 detects that the temperature of the turbine 111 is greater than or equal to the first preset temperature, the control system 320 controls to send out a first warning signal and controls to keep the turbine 111 to still work normally; when the temperature detecting device 310 detects that the temperature of the turbine 111 is greater than or equal to the third preset temperature, the control system 320 controls to turn off the power supply 200. In this alternative embodiment, the high temperature treatment of the turbine 111 by the control system 320 is equivalent to only including the first and third stage treatments described above. Because the two alternative embodiments can remind the staff to intervene in advance to solve the problem of temperature rise of the turbine 111 before the temperature of the turbine 111 does not influence the normal work of the breathing equipment, the two alternative embodiments can also be beneficial to reducing the phenomenon that the breathing equipment stops working due to the high temperature of the turbine 111, and finally can also be beneficial to realizing the long-term continuous work of the breathing equipment.
Preferably, the control system 320 includes an early warning unit 321 and a protection unit 322, the early warning unit 321 includes an early warning device 3211 and a first controller 3212, and the protection unit 322 includes a second controller 3221. The first-stage treatment measure and the second-stage treatment measure are controlled by the early warning unit 321, and the third-stage treatment measure is controlled by the protection unit 322. Here, the control system 320 is divided into two parts, namely the early warning unit 321 and the protection unit 322, so that when one unit fails, the other unit can still work normally, so as to realize the double protection effect on the breathing equipment, and thus, the safety and reliability of the breathing equipment can be improved.
Specifically, when the temperature detecting device 310 detects that the temperature of the turbine 111 is greater than or equal to a first preset temperature, the first controller 3212 controls the early warning device 3211 to send a first warning signal, and the turbine 111 is kept to work normally; when the temperature detection device 310 detects that the temperature of the turbine 111 is greater than or equal to a second preset temperature, the first controller 3212 controls the early warning device 3211 to send a second warning signal and controls the turbine 111 to stop working, so that the gas circuit system 100 stops the mechanical control ventilation function; the second controller 3221 controls the power supply 200 to be turned off when the temperature detecting device 310 detects that the temperature of the turbine 111 is greater than or equal to the third preset temperature.
Preferably, the early warning device 3211 includes an indicator light 3201 and a display screen 3202, and the first warning signal includes the indicator light 3201 emitting a first color light; the second warning signal includes a second color light emitted by the indicator light 3201 and a warning language only in the manual ventilation mode displayed on the display screen 3202, wherein the warning language may be at least one of chinese, english or other languages. First colour light and second colour light are the light of two kinds of different colours, and as a preferred implementation scheme of this embodiment, first colour light is yellow light, and second colour light is red light. When the temperature of the turbine 111 reaches different alarm temperatures, different warning signals are sent, so that the worker can quickly identify the high-temperature early warning degree of the temperature of the turbine 111, and the worker can quickly make different processing modes.
