The present invention relates to a sterilizer for an ambulance vehicle, and more particularly, to a sterilizer for an ambulance vehicle capable of killing harmful bacteria and viruses present in a driver's cab and an emergency room of an ambulance vehicle.

In general, paramedics in an ambulance vehicle perform an important task of transporting an unspecified number of patients, and one paramedic in charge of driving and two paramedics located in an emergency room are put in during the process of transporting confirmed patients. .

In addition, there is a risk of secondary infection among paramedics when an ambulance vehicle transports a suspected or confirmed infected person. They must be isolated in a separate location until the test results come out.

However, since harmful bacteria and viruses may exist inside ambulance vehicles that transport suspected or confirmed infections, other paramedics and emergency patients may be secondaryly infected with harmful bacteria and viruses in the process of transporting emergency patients. I was worried.

In addition, although conventionally, harmful bacteria and viruses present in the first aid room are removed by spraying a disinfectant solution inside the first aid room, it is possible to accurately verify whether or not the harmful bacteria and viruses present inside the first aid room are killed. There was no method, and the process of disinfecting the ambulance was cumbersome because the door had to be opened for a certain period of time for ventilation after spraying the disinfectant into the emergency room.

That is, since the control unit 600 determines that the temperature and humidity of the driver's cab 11 and the emergency room 12 are out of the standard range, harmful bacteria and viruses can survive, the harmful bacteria and viruses can be completely removed.

An ambulance vehicle sterilizer according to an embodiment of the present invention emits ultraviolet rays (UV) into the cab 11 as shown in FIGS. A unit 810 and a second ultraviolet ray generating unit 820 which emits ultraviolet rays into the first aid room 12 and whose driving is controlled by the control unit 600 may be further included.

The first UV generator 810 includes a first housing 811 fixedly installed in the cab 11 and a first circuit installed inside the first housing 811 and electrically connected to the control unit 600. A substrate 812 and one or more first ultraviolet ray lamps 813 mounted on the first circuit board 812 and emitting ultraviolet rays when power is supplied from the outside may be included.

The first UV lamp 813 is driven by electric power transmitted from the outside, and when turned on, it radiates ultraviolet rays of a set wavelength to the cab 11 to sterilize harmful bacteria and viruses contained in the air of the cab 11, and the control unit 813 The on/off state can be controlled by the switch operation of 600 .

The second ultraviolet ray generator 820 is installed in the second housing 821 fixedly installed in the first aid room 12 and inside the second housing 821 and electrically connected to the controller 600. A circuit board 822 and one or more second ultraviolet ray lamps 823 mounted on the second circuit board 822 and emitting ultraviolet rays (UV) when power is supplied from the outside may be included.

The second UV lamp 823 is driven by electric power transmitted from the outside, and emits ultraviolet rays of a set wavelength to the first aid room 12 when turned on to sterilize harmful bacteria and viruses contained in the air of the first aid room 12. , the on/off state can be controlled by the switch operation of the control unit 600. That is, the disinfectant solution L1 is sprayed through the first disinfectant spray unit 300 and the second disinfectant spray unit 400, and at the same time diverged through the first ultraviolet ray generator 810 and the second ultraviolet ray generator 820. Since harmful bacteria and viruses are removed by ultraviolet rays (UV), sterilization performance can be improved.

Hereinafter, a disinfection process using the sterilizer for an ambulance vehicle according to the present invention will be described. When the sterilizer is driven using the control unit 610 or the wireless control unit 640 of the control unit 600, the first pump 320 of the first disinfectant spray unit 300 and the second pump 320 of the second disinfectant spray unit 400 The pump 420 is driven, and the antiseptic solution L1 is injected in a set amount into the cab 11 through the first pump 320, and at the same time, the antiseptic solution L2 is injected into the emergency room 12 through the second pump 420. ) is injected in a set amount.

At this time, the first pump 320 and the second pump 420 may be driven after both the driver's cab 11 door and the emergency room 12 door of the ambulance vehicle 10 are closed, but the ambulance vehicle 10 After driving the first pump 320 and the second pump 420 with the cab 11 door and the first aid compartment 12 door open, both the cab 11 door and the first aid compartment 12 door are closed. After closing both the door of the driver's cab 11 and the door of the emergency room 12, it is possible to have a period of time (approximately 7 to 10 minutes) to kill harmful bacteria and viruses.

Next, a sample is taken from at least one surface of the cab 11 and the first aid room 12 using the reagent rod 520 of the contamination measuring unit 500, and the contact end 521 of the reagent rod 520 is connected to the main body. After being coupled to 510, the main body 510 is inserted into the mounting hole 531 of the harmful substance measuring device 530, and the harmful substance measuring device 530 analyzes the contamination level of the sample and transmits it to the control unit 600. At this time, the user can visually check the measurement result displayed through the display unit 620 of the control unit 600, and depending on the measurement result, whether or not the first disinfectant spray unit 300 and the second disinfectant spray unit 400 are additionally driven. etc. can be determined.

On the other hand, in the case of using a biological sterilization indicator (BI: Biological Indicator), the sterilization indicator (BI) installed in one or more of the driver's cab 11 and the first aid room 12 is collected and 55 to 60? It is possible to confirm sterilization of 6log (6Log Reduction, that is, based on a reduction rate of 99.9999%) or more by confirming the death of harmful bacteria and viruses by putting it in an incubator for 7 days at the temperature.

Finally, the drive shaft of the blower motor 210 of the blower 200 is rotated, suction pressure is applied to the flow path 101 of the discharge passage 100 by the rotation of the blower fan 220, and the intake port 110 After the air (A) introduced through ) is moved along the flow path 101, it is exhausted to the outside of the ambulance vehicle 10 through the exhaust port 120. In this process, harmful bacteria and viruses present in the cab 11 and the emergency room 12 can be exhausted to the outside of the ambulance vehicle 10 through the exhaust port 120, and the driver's cab 11 and the emergency room 12 The disinfectant L1 remaining in the ambulance can also be exhausted to the outside of the ambulance vehicle 10, and the blowing unit 200 in a state where both the driver's cab 11 door and the first aid room 12 door of the ambulance vehicle 10 are closed. ) can be driven.

In addition, the disinfectant solution L1 may be removed by wiping the driver's cab 11 of the ambulance vehicle 10 and furniture and manipulators of the emergency room 12 with an alcohol tissue (not shown) or the like. There are disinfecting tissues made of various raw materials on the market, but it is preferable to use alcohol tissues using 70% ethyl alcohol and 30% purified water or 80% ethyl alcohol and 20% purified water.

As a result, the present invention can kill harmful bacteria and viruses present in the driver's cab 11 and the emergency room 12 after transporting emergency patients (confirmed infection, etc.), thereby preventing secondary infection of paramedics and emergency patients. The driver's cab 11 and the emergency room 12 can be periodically disinfected and the sterilization status of the driver's cab 11 and the first aid room 12 can be periodically checked to hygienically manage the ambulance vehicle 10. In addition, since the sterilization process and the ventilation process of the driver's cab 11 and the emergency room 12 are sequentially performed, harmful bacteria and virus removal performance can be improved.

So far, specific embodiments of the ambulance vehicle sterilizer according to the present invention have been described, but it is obvious that various modifications are possible within the limits that do not depart from the scope of the present invention.
