In the above method, the medical device may be a laser treatment device or a strong light treatment device, and the core device refers to a main component of the medical device, for example, a laser in the laser treatment device or a light source device in the strong light treatment device. Other functional modules include functional modules that protect core devices, such as cooling systems, etc., and the method of the present embodiment may be applied to a variety of different medical devices, and is widely applicable.
In the step a3, the working environment data of the medical equipment may be judged by separately setting components, or may be judged by components having a logic judging function in the medical equipment.
In this embodiment, no matter the laser treatment device or the intense light treatment device, since the core device generates high temperature during operation, the power-down condition in step a4 is as follows: the temperature of the core device is less than a temperature threshold, which may be preset according to different core devices. In other embodiments, the power down conditions may be adjusted for different core devices.
In one embodiment, the temperature of the core device may be obtained by measuring the water temperature of the cooling water flowing through the core device, and further, in order to ensure that the water temperature of the cooling water is obtained by measuring when the cooling water flows and cools normally, the inaccuracy of the measured temperature caused by the too small flow of the cooling water is avoided, the occurrence of a problem of the cooling system is avoided, and the measurement can be started when the flow of the cooling water is greater than or equal to the flow threshold. Furthermore, it is preferable to perform the measurement just after the cooling water flows out of the core device portion, i.e., a measurement point of the temperature is adjacent to the core device, and the measured value can be regarded as the actual temperature of the core device. The flow threshold of the cooling water can be set according to different medical equipment. Moreover, shutdown judgment can be realized only by judging the flow rate and the temperature of cooling water, and the implementation cost can be reduced without adopting a plurality of power modules and a complex software system.

When the medical equipment receives the starting instruction, the medical equipment responds to the starting instruction, and the power supply system enters a pre-starting state. In the pre-power-on state, the core device of the medical device is not powered on, but the other functional modules are powered on. When the working environment data of the medical equipment meet the power-on condition, the power supply system controls the core device to be powered on. The power-on condition can be set according to different use environments of the medical equipment. The starting-up method in the embodiment can enable the core device to be electrified in a proper use environment, and further improves the protection of the core device.
In a third aspect, an embodiment of the present application further provides a shutdown device of a medical device, which may be used to implement the shutdown method. As shown in fig. 2, the shutdown device includes a sensor, a control module, and a power supply system, and the medical apparatus is connected to the mains supply through the power supply system of the shutdown device.
The sensor is used for collecting working environment data of the medical equipment.
The power supply system comprises a power supply loop for connecting the power supply J2 to the mains supply J1 and a power supply J2 for powering the core devices and other functional modules (not shown) of the medical device.
The control module is used for controlling the power supply J2 to power down the core device in a pre-shutdown state, and the power supply J2 is kept to power on other functional modules through connection of a power supply loop and the mains supply J1. The control module is also used for judging whether the medical equipment meets the power-down condition according to the working environment data acquired by the sensor, and controlling the power supply loop to be disconnected on the premise of meeting the power-down condition, so that the connection between the commercial power J1 and the power J2 is disconnected, and other functional modules are powered down.
In the present application, the control module adopts hardware, such as a single-chip microcomputer, a controller, etc., and in this embodiment, the control module adopts the single-chip microcomputer.
Further, in one embodiment, as shown in fig. 2, the power supply system includes an ac contactor K1, a dc contactor K2, and a start button S1. Specifically, the power supply system obtains an instruction from the outside through the start button S1, when the start button S1 is not pressed, all components in the medical equipment are in a state of not being electrified, and when the start button S1 is pressed, the power supply system obtains a start instruction; when the start button S1 is reset, the power supply system obtains a shutdown instruction and enters a pre-shutdown state. In the pre-shutdown state, a closed power supply loop is formed by the control end of the alternating current contactor K1, the output end of the alternating current contactor K1 and the output end of the direct current contactor K2, and a power supply J2 is connected to a commercial power J1; but at this time, the power supply J2 does not supply power to the core device.
Further, in one embodiment, as shown in fig. 3, the start button S1 includes two sets of switches, wherein the normal ends (contacts 1, 3) of the first set of switches (contacts 1,2, 3) are connected to the ac contactor K1, and the second set of switches (contacts 4, 5, 6) are connected to the control module. The two groups of switches are arranged to play a role in both the control module and the power supply loop, and under the effect of electrifying the power supply loop, the control module can obtain different states of the starting button so as to control the power supply J2 to be timely powered off in a pre-shutdown state.
As shown in fig. 2 and 3, the power-on procedure of the medical device includes: when the start button S1 is pressed, the normally open end (contact 1 and contact 3) of the power source J2 is closed, and the control end (pin 8) of the ac contactor K1 forms a power-on loop through the start button S1 and the output end (contact 1 and contact 4) of the dc contactor K2 to perform power-on. The output of the ac contactor K1 (pins 4 and 5, pins 1 and 2) is thus closed, at which time the mains J1 can supply power to the power supply J2 via the output of the ac contactor K1; but the power supply J2 does not supply power to the core device. And after the working environment data collected by the sensor meet the power-on condition, the power supply J2 powers on the core device. In the embodiment, other functional modules are powered on firstly, and then the core device is powered on, so that the core device is ensured to be powered on when the working environment is proper, and the risk of damage to the core device is reduced.
Further, in an embodiment, the shutdown procedure of the medical device includes: when the start button S1 is reset, the power system obtains a shutdown instruction, two sets of switch states of the start button S1 change (the contact 1 and the contact 2 are conducted, the contact 4 and the contact 5 are conducted), and the control module enters a pre-shutdown state. At this time, the power supply J2 is powered off the core device, and since the output end of the ac contactor K1 is closed and turned on after the medical device is started, the control end of the ac contactor K1 may form a closed power supply loop through the output end of the ac contactor K1 and the output end of the dc contactor K2, so that the power supply J2 is kept powered on, and at this time, the power supply J2 may still supply power to other functional modules. The sensor continuously collects working environment data of the medical equipment and transmits the working environment data to the control module, when the power-down condition is met, the control module controls the output end of the direct current contactor K2 to be disconnected, the power supply loop is disconnected, the power supply J2 is disconnected from the mains supply J1, and other functional modules are powered down at the moment. In this embodiment, the core device is powered down first, and the other functional modules are powered down later, so that the possibility of damage to the core device is reduced and the service life of the core device is prolonged in the previous working environment after the core device is powered down.
Further, in an embodiment, as shown in fig. 2, the shutdown device further includes a fuse F1, the fuse F1 is disposed in the power supply circuit, the fuse F1 is connected between the control end of the ac contactor K1 and the dc contactor K2, the fuse F1 is connected to the live wire, and when the input current of the power source J2 exceeds the limit value of the fuse F1, the fuse F1 automatically disconnects the live wire. In this embodiment, when the current is too large, the power supply loop can disconnect the live wire through the fuse F1, so as to realize immediate power failure of the medical equipment and protect the medical equipment.
Further, in an embodiment, the shutdown device further includes a scram button S2 disposed in the power supply circuit, where the scram button S2 is configured to power off the power supply circuit when receiving the stop command. Specifically, the emergency stop button S2 can be disconnected from the live wire through the control end of the ac contactor K1, so as to realize manual emergency stop of the medical equipment, and protect the medical equipment when the medical equipment works abnormally.
Further, in an embodiment, as shown in fig. 3, the control module may use a single-chip microcomputer, and the power supply system and the single-chip microcomputer implement transmission of instructions through an optocoupler. Specifically, the second group of switches of the starting button S1 is connected with the singlechip through the first optocoupler ISO1, and the singlechip is also sequentially connected with the second optocoupler ISO2, the triode Q1 and the direct current contactor K2. After the start button S1 is reset, the first optocoupler ISO1 sends a low level to the singlechip, the singlechip sends a low level to the second optocoupler ISO2, the pin connected with the triode Q1 is turned into a high level after the second optocoupler ISO2 is conducted, the triode Q1 is further conducted, the pin connected with the triode Q1 by the direct current contactor K2 is changed into a low level, the direct current contactor K2 is switched through an internal pin, the control end of the alternating current contactor K1 is disconnected from a live wire, a power supply loop is disconnected, and other functional modules are powered down.
Referring to fig. 3, a schematic circuit diagram of an embodiment of a power supply system is shown, where the working principle of the power supply system is specifically described by a circuit. In this embodiment, the live wire (AC 220V-L) of the utility power J1 is connected between the fuse F1 and the emergency stop button S2, and the neutral wire (AC 220V-N) of the utility power J1 is connected between the power source J2 and the output terminal of the AC contactor K1, wherein the emergency stop button S2 is normally closed. The power supply J2 is connected to the mains supply J1 through a power supply loop, and when the power supply loop is disconnected, the power supply J2 is powered down.
When the medical equipment is started, the starting button S1 is pressed, the contact 1 and the contact 3 (normally open end) of the starting button S1 are conducted, and the contact 4 and the contact 5 are disconnected. At this time, because the start button S1, the scram button S2, the pin 1 and the pin 4 of the dc contactor K2 are all turned on, the pin 8 and the live wire of the ac contactor K1 are turned on, and the pin 7 and the zero line of the ac contactor K1 are turned on, so that the ac contactor K1 starts to close the output end, that is, the pin 1 and the pin 2 are closed, the pin 4 and the pin 5 are closed, so that the power J2 and the live wire are turned on, the power J2 supplies power to other functional modules, and the power J2 does not supply power to the core device at this time. And when the working environment data collected by the sensor meets the power-on condition, the control module controls the power supply J2 to power on the core device.
When the medical equipment is shut down, the starting button S1 is pressed down again to reset, the contact 1 and the contact 3 of the starting button S1 are disconnected, and the contact 4 and the contact 5 are conducted. At this time, although the start button S1 is reset, the pin 1 and the pin 2 of the ac contactor K1 are closed, the pin 4 and the pin 5 are closed, the control terminal (pin 8) of the ac contactor K1 can still be powered on through the output terminal (pin 4 and pin 5), the scram button S2, the power supply circuit where the pin 1 and the pin 4 of the dc contactor K2 are located, and the power supply J2 can still supply power to other functional modules. However, when the start button S1 is reset, after the contact 4 and the contact 5 are grounded, the pin 1 and the pin 2 of the first optocoupler ISO1 are turned on, the pin 4 of the first optocoupler ISO1 becomes low level, and the control module (not shown) immediately enters a pre-shutdown state. In the pre-shutdown state, the control module controls the power supply to stop supplying power to the core device, and the core device (not shown) is powered down.
When the control module judges that the power-down condition is met according to the working environment data collected by the sensor, the control module sends a low level to the second optical coupler ISO2, the pin 1 and the pin 2 of the second optical coupler ISO2 are conducted, the pin 3 of the second optical coupler ISO2 becomes a high level, the pin 1 and the pin 3 of the triode Q1 are conducted, the pin 2 of the direct current contactor K2 becomes a low level, the pin 1 and the pin 3 of the direct current contactor K2 are attracted, the pin 1 and the pin 4 are disconnected, the pin 8 and the fire wire of the alternating current contactor K1 are disconnected, the pin 1 and the pin 2 of the alternating current contactor K1 are disconnected, a power supply loop is disconnected at the moment, the connection between the power supply J2 and the commercial power J1 is disconnected, the power J2 is not supplied for other functional modules, the other functional modules are powered down, and the whole medical equipment is powered down.
Further, since the fuse F1 is connected in series in the power supply loop and is connected with the live wire, when the input current of the power source J2 exceeds the limit value of the fuse F1, the fuse F1 automatically breaks the live wire, and the power supply loop is broken, so that the whole medical equipment is powered down, and fuse protection is realized.
Further, since the emergency stop button S2 is connected in series in the power supply loop, when the operation of the medical equipment is abnormal and needs to be stopped immediately, the emergency stop button S2 can be pressed, the normally closed contact of the emergency stop button S2 is disconnected, so that the pin 8 of the ac contactor K1 is disconnected from the live wire, the power supply loop is disconnected, and the whole medical equipment is powered down and stops running immediately.
In the embodiment, as the hardware structure is adopted, the core device can be powered down firstly and then other functional modules are powered down without adopting a plurality of power modules and a complex software system, thereby greatly reducing the damage possibility of the core device and prolonging the service life of the core device. And the adopted components are mature components, so that the structure is simple, and the cost is saved as a whole.
The application is not limited to the above-mentioned circuit embodiment in fig. 3, and in other embodiments, other circuit forms may be provided, so long as it can ensure that the formed power supply loop can still supply power to the power supply in the pre-shutdown state, and can receive the control of the control module to perform power-down.
