The box also contains an internal pocket for medications, ports for connecting to external devices, two stand-alone filter-ventilation units with a microprocessor-based air supply and air removal control system, which can operate in negative and positive pressure modes with the ability to monitor the battery charge level through the indicator scale and connected to any external power sources, high-purity anti-aerosol filters, additional fixation belts ii ankle and the patient's body. New is that a longitudinal spacer is installed on the arches in the retaining sockets at the top of the chamber frame, hermetic glove ports for access to the patient are made with gloves secured through a plastic cuff and o-rings, the box is equipped with a system for regulating pressure, temperature and humidity inside the chamber through built-in sensors with data output to the display panel, a gateway on two pressurized lightnings for the safe introduction of additional drugs and consumables during the transfer Oski patient to a stretcher mounting box system. Boxing contains a magnetic key and mode selection sensors, providing the inclusion of a boxing control system.

Also, the box can be additionally equipped with two cascades of anti-aerosol and / or anti-chemical filters of high-class air purification at each filter-ventilation unit.

Additionally, the box may contain a console located in the head part, which includes a lighting system, an emergency sound and visual alarm system, a doctor’s call system, a Bluetooth data transmission system, an event recording system with the option of uploading to external media.

Also, the patient transport box may further comprise a removable internal portable stretcher mattress and a folding external stretcher.

In order to prevent the penetration of microorganisms through the box structure during operation at the negative pressure maintenance mode, the box is made in the form of an inflatable airtight chamber made of a strong, mainly transparent plastic material for placing the patient lying down, with a frame that is separate transverse arches, internal arches are fixed at the base of the chamber in the holding pockets, and along the top of the camera frame on the arches in the holding connectors there is a longitudinal strut.

All seams are made using high-quality welding technology, followed by sealing with tapes of the main material using high-temperature splicing with hot air, which ensures that the seams do not diverge during operation.

All connections are stationary, the absence of removable parts allows to ensure the greatest tightness of the device and to avoid incorrect assembly of the structure. The exception is replacement gloves and filters.

The essence of the claimed utility model and the possibility of its practical implementation is illustrated by the description and drawings below, where in FIG. 1 and 2 show a general view of the box from different sides.

To understand the essence of the technical solution in FIG. 1 and 2 positions denote the following elements: 1 - glove ports, 2 - glove mount, 3 - patient attachment system, 4 - system for attaching the box to a stretcher, 5 - ports for connecting to external devices, 6 - transfer gateway, 7 - aerosol and / or combined filters of high-class air purification, 8 - supply and exhaust system with filtering installations (hereinafter the supply and exhaust system), 9 - display control panel, 10 - pressure relief, 11 - stretcher mattress, 12 - internal pocket, 13 - magnetic key, 14 - sensors selection p Benches work box control system, 15 - separate crossbars, 16 - control unit 17 - the indicator light mode box, 18 - a longitudinal strut.

When evacuating the patient, first of all, it is necessary to open the box by unfastening the zipper 10, put the patient inside with the help of a stretcher mattress 11, fixing it with the patient fastening system 3 (belts for fixing the ankles and the patient’s torso). Germ lightning 10 is located around the perimeter indented from the bottom of 10-15 centimeters with the direction of closing the lightning from legs to head. The system of fastening the box to the stretcher 4 allows you to fix it on a typical ambulance stretcher-wheelchairs for transportation (transfer and transportation) of the patient.

Using glove ports 1, operators manipulate the patient, injectable drugs and syringes are stored in a special inner pocket 12. Glove ports 1 are made with 2 gloves fastened through a plastic cuff and o-rings, have a convenient shape (size and angle) the operator was comfortable with the patient. After turning on the supply and exhaust system 8, the patient is fully provided with the necessary amount of air for comfortable transportation in the selected operating mode (at positive or negative pressure), anti-aerosol or combined filters of high class air purification 7 protect against dangerous bacteria, viruses, radioactive dust and highly toxic particles. The supply and exhaust system 8 provides the necessary flow of purified air, does not require reconfiguration with the help of mechanical permutations of the fans. The supply and exhaust system 8 is equipped with two radial fans (supply and exhaust, not shown in Fig. 1 and Fig. 2) and is made in a single housing with a microprocessor-based air supply and exhaust control system and an integrated automatic pressure maintenance system at +50 Pa when operating in positive pressure mode and -50 Pa when operating in negative pressure mode, it is made with the ability to track the charge level of batteries, is equipped with built-in sensors for pressure, temperature and humidity inside measures (in Fig. 1 and Fig. 2 not shown) with data output to the display panel 9, with the possibility of working offline from batteries and the ability to connect to external power sources.

If it is necessary to supply infusion solutions or connect an ECG apparatus and artificial lung ventilation, it is possible to connect to external devices using ports 5, the transfer of drugs is carried out through a transfer gateway 6.

Visual control of the pressure inside the system is displayed on the control panel 9.

The control system of the box is switched on using a magnetic key 13 and mode selection sensors 14 or an external control panel 16. The microprocessor system controls the air supply, providing the necessary pressure and temperature inside the chamber, as well as the volume of air supplied. The control is performed by automatic smooth regulation of the speeds of the supply and exhaust fans depending on the operating mode selected by the user (positive pressure inside the insulator or negative). A system for regulating and controlling the temperature of the supplied air (heating and cooling), controlled by a microcontroller, is built into the duct of the supply fan.

The indicator light 17 is designed to monitor the operating mode of the transport insulating box, made in the form of an indicator lamp located on the end of the insulating chamber above the front panel. The indicator lamp has the following colors: blue in the "positive pressure" mode, green in the "negative pressure" mode, when the filter and ventilation unit reaches the selected mode, the lamp flashes red. The threshold values of the parameters beyond which the alarm system is triggered: when operating in the "Negative pressure" mode, the values are: minus 80 Pa - minus 10 Pa; when operating in the "Positive pressure" mode, the values are: plus 10 Pa - plus 100 Pa. When an alarm is triggered, the indicator lamp flashes red, the lamp flashing is additionally accompanied by an audible alarm.

Autonomous power supply of the air supply system is provided by a Li-ion battery. Requirements for external power sources - 220V network, 50 Hz. Charger - 220 V / 24V, 4 A.

The box contains separate transverse arcs 15, mounted in the base of the camera in the holding pockets. A longitudinal strut 18 is mounted on top of the camera frame, mounted on 4 retaining connectors

The insulated box for transporting patients ensures the following technical result - to prevent the penetration of microorganisms, dust particles and chemicals through the box during operation while maintaining a negative or positive pressure.

The presented box is used for transporting, for example, burn patients and immunocompromised patients to protect them from the “polluted” environment, as well as patients suspected of being infected with a particularly dangerous infection.
