DE2421693A1 - Ambulance with separate patient's compartment - has increased air exchange and disinfection of air prior to entering atmosphere - Google Patents

Abstract

Ambulance comprises a driver's cab, and a separate patient's compartment including an air inlet germ filler and an air suction pipe which is connected to the engine via a pipe opening out behind the engine air filter, so that air is disinfected by passing through the engine itself before entering the atmosphere. The heat of the engine is used to kill the harmful germs. The drawing also shows in the air inlet germ filter a filter insert which is mounted in a disinfecting fluid circuit comprising a receptacle containing formalin, a pump, and a drain pipe for returning formalin to the receptacle.

Description

Ambulance vehicle addendum to patent ... (patent application P 21 51 434.1) The main patent relates to an ambulance vehicle with the driver's cab separate patient cabin, the patient cabin having an air inlet germ filter and associated with a device which sets its interior space to a low negative air pressure whose exhaust air is before it enters the open air a disinfection zone flows through.

The main patent creates an ambulance vehicle, which is suitable for a longer time transport of people with infectious diseases suitable.

This ambulance vehicle is designed so that in the patient room any air that is enriched with germs cannot escape and can thus offer a risk of infection, but cleaned before it escapes into the open i.e. the germs contained in the air are killed. this happens according to the main patent in that the air sucked out of the patient room before The exit to the outside passes through a disinfection zone that is different from the standard Vehicle heater or an additionally installed heater is formed by all germs are killed by the high temperatures.

The object of the present invention is, in particular, i.e. in addition for the tasks resulting from the description and claims, the main application P 21 51 434.1 to the effect that the killing of germs before Most of the used air escapes into the open air without additional Device and moreover takes place with increased air exchange.

This object is achieved by the invention specified in claim 1.

The subclaims represent advantageous developments of the invention represent.

As a result of such a design, the main patent is expanded so that an ambulance vehicle of increased utility value with the simplest design is achieved. The used air in the patient room is released into the open air and without additional disinfection devices to flow directly through the existing one Drive motor of the vehicle supplied. The advantage here is that already existing necessary energy, namely the high combustion temperature of the engine is used to kill germs. The used air in the patient room is fed to the engine in such a way that it can be used together with the fuel the required fuel-air mixture forms and after combustion from the exhaust is performed. On the one hand, the advantage is thus achieved that no additional Devices are necessary, on the other hand no additional energy has to be applied be used to operate such devices and, moreover, is finite through the very high combustion temperatures of the vehicle engine in any case an absolute safe killing of germs guaranteed. Furthermore, through this Disinfection process has the advantage that there is an improved exchange of air in the patient room comes about because the engine continuously draws in relatively large amounts of air. By this suction of the motor also eliminates the need for an additional fan, which maintains the patient room at a desirable slight negative pressure. Such a fan can, however, also be provided if necessary, in order to, for example in transport cases that do not involve isolation or killing of germs the discharge of the air into the open require this air directly without prior combustion to be ejected by the vehicle engine. To this The purpose is the air intake point between the internal combustion engine and the pipeline that removes the stale air the patient room, created so that, for example, by a three-way valve a change of the air intake is possible so that the air for the Fuel mixture on the one hand can be sucked in directly through the usual air filter can or after conversion exclusively via the air intake from the patient room supplied stale air.

The special arrangement of the air intake also ensures that With the appropriate setting of the three-way valve, none enriched with germs Air can get into the existing air filter and from there to the outside. The suction the consumed breathing air via the engine also has the advantage that through the well-known mode of operation of the engine backfire deflagrations are excluded.

The object of the invention is based on a drawing after standing explained in more detail.

The ambulance vehicle shown has the driver's cab 1 and the adjoining, separate patient room 2.

All outer windows 3 of the patient room are installed airtight and germ-tight, while the entrance doors have seals that are impermeable to air and germs.

On the outside of the vehicle, there is a fan on the ceiling 4 of the patient room 2 5 provided, the outside air through an air inlet germ filter 6 in the below patient room 2 with a low negative pressure. The outside air wanders through here a filter insert 7, which is in the flow circuit of a disinfectant liquid is switched on. The latter consists for example of housed in a container 8 Formally in and is fed to the filter insert via a pump 9. After soaking the With the filter insert 7, the formalin flows through the collecting tube 10 into the container 8 return.

In the area of the patient room floor 11 there is an air intake connector 12 appropriate. This air intake connection 12 can work together with a fan, however, in the drawing, a pipe 60 extends directly from the air intake port, which leads directly to the air intake point 61 of the existing vehicle moor 62.

The vehicle engine thus receives the information required for the composition of the fuel mixture necessary amount of air directly through the pipe 60 from the patient room 2.

The intake point 61 of the vehicle engine has a three-way flap 63 equipped, which can be adjusted so that the required air only sucked out of the pipe 60 or exclusively through the existing air filter 64 will.

The germs contained in the stale air you breathe become burned with the fuel in the engine, with the combustion residue subsequently be carried out in a known manner via an exhaust pipe.
