Based on the above description of the laser sterilization system, a laser sterilization apparatus in the laser sterilization system will be described next.

Fig. 2 is a schematic structural diagram of a laser disinfection apparatus provided in an embodiment of the present invention, and referring to fig. 2, the laser disinfection apparatus provided in the embodiment of the present invention includes: an electronic control unit 21, a laser 22, and a laser guiding system 23 connected to the laser 22; wherein the content of the first and second substances,

an electronic control unit 21 for outputting a first control signal for controlling the laser;

a laser 22 for outputting laser light having a wavelength of 0.2 to 3.0 μm based on an input first control signal;

and the laser guide system 23 is used for guiding laser to be output by the laser guide system to irradiate the target area or the target object, so that the target area or the target object can be disinfected or sterilized after the laser is irradiated.

Here, the electronic control unit 21 may be an integrated circuit chip having Signal processing capability, such as a general purpose processor, a Digital Signal Processor (DSP), or other programmable logic device, discrete gate or transistor logic device, discrete hardware components, etc., wherein the general purpose processor may be a microprocessor or any conventional processor, etc.

In practical implementation, the laser 22 may be a solid laser, a semiconductor laser, or a fiber laser, and when the laser is a solid laser, the laser is composed of a laser working substance, a pumping source, a resonator mirror, and the like; specifically, in some embodiments, the laser working substance of the solid-state laser is a crystal rod, and the adopted pump source is a flash lamp or a laser diode, that is, the flash lamp or the laser diode emits light, and the crystal rod absorbs energy of the flash lamp or the laser diode to generate laser; the solid laser has the characteristics of small volume, convenient use, large output power and the like.

In some embodiments, the number of lasers 22 may be one or more; when the number of the lasers is two or more, the wavelengths of the laser light output by different lasers are the same or different; specifically, when the number of the lasers is two or more and the wavelengths of the laser lights output by the different lasers are the same, the number of the laser guiding systems is one, and the one laser guiding system is specifically configured to guide the laser lights output by the two or more lasers to be combined and output through the laser guiding system; when the number of the lasers is two or more and the wavelengths of the laser output by different lasers are different, the number of the laser guiding systems is two or more, wherein the lasers and the laser guiding systems are in one-to-one correspondence.

For example, when the target area or the target object is small, such as the surface area is less than 0.1 square meter, and particularly when disinfection and sterilization are performed on medical scissors, medical forceps, etc., the number of the lasers 22 may be one, the laser wavelength output by the lasers 22 may range from 0.2 micrometers to 3.0 micrometers, and after the laser is output by the laser guidance system and irradiated to the target area or the target object, killing of microorganisms or bacteria is achieved by the instantaneous high temperature.

When the target area or target object is large, such as a surface area greater than 0.1 square meter, and particularly when disinfection and sterilization are performed for a medical instrument cabinet, the number of the lasers 22 may be two or more, for example, two, first and second lasers, respectively, and the laser wavelengths of the outputs of the first and second lasers may be the same or different.

Specifically, when there are objects that do not resist high temperature (taking high temperature as an example of 134 ℃) among a plurality of objects to be disinfected/sterilized, or there are parts that do not resist high temperature (for example, the target object includes a stainless steel part and a plastic part, the plastic part does not resist high temperature) in a single object, the laser wavelengths of the outputs of the first laser and the second laser are different, and at this time, the laser wavelengths of the outputs of the first laser and the second laser are in the range of 0.2 micrometers to 3.0 micrometers, for example, the laser wavelength of the output of the first laser is 0.8 micrometers, and the laser wavelength of the output of the second laser is 2.1 micrometers; or the laser wavelength output by the first laser is 1064nm, and the laser wavelength output by the second laser is 2140nm, specifically, the laser wavelengths output by the first laser and the second laser may be set according to actual needs, which is not limited in this embodiment;

correspondingly, the number of the laser guidance systems 23 is two, and the two laser guidance systems are respectively a first laser guidance system corresponding to the first laser so that the laser output by the first laser is guided by the first laser guidance system and then output, and a second laser guidance system corresponding to the second laser so that the laser output by the second laser is guided by the second laser guidance system and then output.

When no object which does not resist high temperature exists in a plurality of objects to be disinfected/sterilized or no part which does not resist high temperature exists in a single object, the laser wavelengths output by the first laser and the second laser are the same, at the moment, the laser wavelength range of the output of the first laser and the second laser is 0.2-3.0 micrometers, and if the laser wavelengths of the output of the first laser and the second laser are both 1.8 micrometers; or the laser wavelengths output by the first laser and the second laser are both 1064nm, and specifically, the laser wavelengths may be set according to actual needs, which is not limited in this embodiment;

accordingly, the number of the laser guiding systems 23 is one, that is, the laser light output by the first laser and the laser light output by the second laser are combined and output through the laser guiding systems.

In practical applications, the laser output mode of the laser 22 may be various, such as a pulse output mode, a continuous output mode, a combined mode of pulse output and continuous output, when a user uses the laser disinfection apparatus, the laser output mode may be adjusted according to actual needs, and in some embodiments, the electronic control unit 21 is further configured to output a third control signal for controlling the laser 22; accordingly, the laser is further configured to adjust the laser output mode corresponding to the laser 22 to a target output mode based on the input third control signal, where the target output mode is one of the following: pulse output mode, continuous output mode, and combination mode of pulse output and continuous output.

In practical applications, when the laser output mode of the laser 22 is a pulse output mode, the action duration of the laser needs to be adjusted for different objects to be disinfected/sterilized, and at this time, the pulse width of the laser 22 needs to be adjusted; in some embodiments, the electronic control unit 21 is further configured to output a second control signal for controlling the laser 21; correspondingly, the laser 22 is further configured to adjust the pulse width of the output laser to a target pulse width value based on the input second control signal; in practical applications, the target pulse width value corresponds to a pulse width range of 1 femtosecond to 1000 milliseconds.

Here, the adjustment of the pulse width of the laser light output from the laser 22 may be continuous adjustment or intermittent adjustment; for continuous adjustment, the pulse width knob may be rotated by a user, and when the user rotates the pulse width knob, the pulse width output by the laser 22 is smoothly increased or decreased, that is, when the user rotates the pulse width knob, the change of the pulse width of the laser output by the laser 22 and the rotation of the pulse width knob are in a linear relationship; for the interval adjustment, the pulse width key can be triggered (e.g. clicked) by a user, and for the single triggering of the pulse width key, the pulse width variation of the laser output by the laser 22 is a fixed value (the specific size can be set according to the actual requirement); for example, when the user wants to increase the pulse width of the laser light output from the laser 22, the pulse width increasing button is clicked, and the pulse width of the laser light output from the laser 22 is increased by 10 ms, whereas when the user wants to increase the pulse width of the laser light output from the laser 22 by 30 ms, the pulse width increasing button needs to be clicked three times.

In practical application, the laser disinfection and sterilization equipment can have different laser output guide modes, such as a fixed mode or a handheld mode, and a user can switch the laser output guide modes according to actual needs.

In some embodiments, the laser guidance system 23 includes at least one of: optical fiber, light guide arm, galvanometer; for different laser output guidance modes or situations where the number of the laser guidance systems 23 is different, the optical fiber, the light guide arm, and the galvanometer may be adaptively selected, for example, for situations where the number of the laser guidance systems 23 is one and the laser output guidance mode is handheld, the optical fiber or the light guide arm may be selected as the laser guidance system 23 of the laser disinfection and sterilization apparatus; aiming at the condition that the number of the laser guide systems 23 is two and the laser output guide mode is a handheld type, the optical fiber and the light guide arm can be selected to be used as the laser guide system 23 of the laser disinfection and sterilization equipment in a cooperative manner, or the two optical fibers are selected to be used as the laser guide system 23 of the laser disinfection and sterilization equipment in a cooperative manner, or the two light guide arms are selected to be used as the laser guide system 23 of the laser disinfection and sterilization equipment in a cooperative manner; in the case where the laser output guidance mode is fixed, at least one galvanometer may be selected as the laser guidance system 23 of the laser disinfection apparatus.

In practical application, in order to ensure the safety of the sterilized/disinfected object, the output duration of the laser can be controlled; in some embodiments, the electronic control unit 21 is further configured to monitor a duration of the laser light output by the laser 22, and output a fourth control signal for controlling the laser 22 when the duration reaches a target duration, so that the laser 22 stops outputting the laser light.

In some embodiments, the laser disinfection apparatus further comprises a power supply for powering the laser disinfection apparatus.

In some embodiments, the laser disinfection apparatus may further comprise a user interface comprising one or more output devices enabling presentation of laser parameters, including one or more speakers and/or one or more visual display screens; the user interface also includes one or more input devices, including user interface components that facilitate user input, such as a microphone, a touch screen display, a camera, other input buttons and controls.

In some embodiments, the laser disinfection apparatus may also include memory, including volatile memory or non-volatile memory, and may also include both volatile and non-volatile memory. The nonvolatile Memory may be a Read Only Memory (ROM), and the volatile Memory may be a Random Access Memory (RAM). The memory described in embodiments of the present invention is intended to comprise any suitable type of memory; in some embodiments, the memory is capable of storing data, examples of which include programs, modules, and data structures, or a subset or superset thereof, to support various operations.

The laser disinfection method provided by the embodiment of the invention is described by taking the number of the lasers included in the laser disinfection device as two examples. Fig. 3 is a schematic structural diagram of a laser disinfection apparatus according to an embodiment of the present invention, and fig. 4 is a schematic flow diagram of a laser disinfection method according to an embodiment of the present invention, which will be described with reference to fig. 3 and fig. 4.

Referring to fig. 3, the laser sterilization apparatus according to the embodiment of the present invention includes: a display unit 31, an electronic control unit 32, a first laser 331, a second laser 332, a first laser guiding system 341, a second laser guiding system 342, and a power supply unit 35.

With reference to fig. 3, in practical applications, before laser output is performed by using the laser disinfection apparatus, the relevant laser parameters may be configured, and the display unit 31 included in the laser disinfection apparatus may be a touch display screen, a liquid crystal display screen, or the like, and the laser parameter configuration interface of the disinfection apparatus is presented through the display unit, and at least one of the following is displayed in the laser parameter configuration interface:

a laser selection function item for performing laser selection, a laser wavelength function item for performing output wavelength configuration for the first laser 331 and the second laser 332, a laser output mode function item for performing laser output mode configuration for the first laser 331 and the second laser 332, and a laser output guidance mode function item for configuring a laser output guidance mode.

In a first example, a user selects the first laser 331 and the second laser 332 for laser output through a laser selection function item according to actual needs; the laser wavelength of the first laser 331 and the laser wavelength of the second laser 332 are selected to be the same through the laser wavelength function item, and the laser wavelengths are both 1064 nm; the laser output modes of the first laser 331 and the second laser 332 are selected to be the same through the laser output mode function item, and are pulse output modes; and, the laser output guidance mode is selected to be a handheld type through the laser output guidance mode function item.

Here, the selection of the laser output guidance method will be described. In practical implementation, the laser output guidance modes presented by the display unit 31 are different according to different practical materials of the first laser guidance system 341 and the second laser guidance system 342, for example, when the first laser guidance system 341 is an optical fiber or a light guide arm, and the second laser guidance system 342 is a galvanometer, the selectable items of the laser output guidance modes presented by the display unit 31 include a handheld type and a fixed type; when the first laser guiding system 341 is an optical fiber or a light guiding arm, and the second laser guiding system 342 is an optical fiber or a light guiding arm, the selectable options of the laser output guiding mode presented by the display unit 31 only include a handheld type; when the first laser guiding system 341 and the second laser guiding system 342 are both galvanometers, the selectable options of the laser output guiding mode presented by the display unit 31 only include fixed types.

Taking the first laser guiding system 341 as a light guiding arm and the second laser guiding system 342 as a galvanometer as an example, and continuing the above first example, since the laser wavelengths of the first laser 331 and the second laser 332 selected by the user in the first example are the same, the laser output by the first laser 331 and the second laser 332 is default to be output by combining through one laser guiding system by the laser disinfection and sterilization apparatus, and at this time, when the laser output guiding mode selected by the user is a handheld type, the laser output by the first laser 331 and the second laser 332 is default to be output by combining through the first laser guiding system 341 by the laser disinfection and sterilization apparatus.

In a second example, a user selects the first laser 331 and the second laser 332 for laser output through a laser selection function item according to actual needs; the laser wavelength of the first laser 331 is 1064nm and the laser wavelength of the second laser 332 is 2140nm according to the laser wavelength function item; the laser output mode of the first laser 331 is selected as a pulse output mode and the laser output mode of the second laser 332 is selected as a continuous output mode through the laser output mode function item, namely the laser output mode of the laser disinfection and sterilization equipment is a combined mode of pulse output and continuous output; the laser output guidance mode of the first laser 331 is selected to be fixed and the laser output guidance mode of the second laser 332 is selected to be handheld.

Here, the selection of the laser output guidance method will be described. Since the laser wavelengths of the first laser 331 and the second laser 332 selected by the user in the second example are different, the laser disinfection apparatus defaults that the laser output by the first laser 331 and the laser output by the second laser 332 are output by the two laser guiding systems, and at this time, the user needs to select the laser output guiding modes of the first laser 331 and the second laser 332 respectively.

In a third example, the user selects only the first laser 331 for laser output through the laser selection function item according to actual needs; the laser wavelength of the first laser 331 is selected to be 2140nm through the laser wavelength function item; and selects the laser output mode of the first laser 331 as the continuous output mode through the laser output mode function item; the laser output guidance mode of the first laser 331 is selected to be fixed.

In actual implementation, when a user completes laser parameter configuration through the laser parameter configuration interface, the laser output instruction may be triggered by triggering the laser output key displayed by the display unit 31, so that the electronic control unit generates a first control signal for controlling the laser device based on the laser output instruction.

Based on the above description of the laser parameter configuration, the laser disinfection and sterilization method provided by the embodiment of the invention is described next.

Step 301: in response to the received laser output instruction, a first control signal for controlling the laser is generated by the electronic control unit.

In practical application, when a user completes laser parameter configuration, a laser output instruction is triggered, after the electronic control unit receives the laser output instruction, the electronic control unit analyzes the instruction to obtain laser parameters configured by the user and carried by the laser output instruction, and a corresponding first control signal is generated according to the obtained laser parameters.

Here, taking the laser parameter configuration completed by the user corresponding to the first example as an example, the first control signal generated by the electronic control unit is used to control both the first laser 331 and the second laser 332 to adopt the pulse output mode, and output the laser with the wavelength of 1064nm, and at the same time, control the lasers output by the first laser 331 and the second laser 332 to be combined and output through the first laser guiding system 341.

Step 302: transmitting a first control signal to the laser.

Here, after the first control signal generated by the electronic control unit is transmitted to the lasers (the first laser 331 and the second laser 332), the first laser 331 and the second laser 332 output laser with a wavelength of 1064nm in a pulse output mode based on the first control signal, and the output laser is combined and output by the first laser guiding system 341, so that the user can irradiate the target area or the target object with the first laser guiding system 341 by hand to sterilize or disinfect the target area or the target object.

By way of example, executable instructions may be deployed to be executed on one computing device or on multiple computing devices at one site or distributed across multiple sites and interconnected by a communication network.

The above description is only an example of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and scope of the present invention are included in the protection scope of the present invention.
