The ideal inflation system for the transfer chamber should be: when the cabin body starts to be inflated, the high-flow rate of 5kPa at low pressure is more than 500L/min, so that the cabin body is molded as soon as possible and reaches a transferring state; and after the cabin body is formed, the high pressure 40kPa low flow 20L/min is transferred to be inflated. However, the existing medical rescue cabin is limited by the quality, the power and the flow, only a single-flow air pump can be used for completing the work, but the flow can not be adaptively adjusted according to the needs, so that the efficiency is not only improved, but also the environmental change in the transportation cabin is nonlinear adjustment, so that the comfort level is not ideal enough, the cabin body is inflated by a single pump source, the performance of the pump source needs to be taken into consideration by the flow of 500L/min and the inflation pressure of 40kPa at the same time, namely the performance of the pump is as follows: the flow rate was 500L/min and the pressure was 40kPa.

The pump quality of this performance is at least above 15kg, the volume is above 400 x 300 x 400mm, no matter the key indexes such as quality, volume, power are suitable for the application of the transport cabin, and more importantly, the flow rate at 40kPa is also not suitable. Although the mass of the air pump with small flow or pressure is smaller, the power is usually less than 100W, and the use requirement cannot be well met. Therefore, there is a need for improvements to existing transfer pod air pumps.

The electric control high-low pressure automatic transfer pump of the wounded transport cabin, as shown in figure 1 and figure 2, comprises a valve plate 1, wherein an air inlet, an air outlet 2 and a detection port 3 are arranged on the valve plate, and the air inlet comprises a low-pressure air pump connection port 4 and a high-pressure air pump connection port 5; the high-pressure air pump connector is connected with a high-pressure air pump 7 through a high-pressure pipeline 6, a low-pressure output one-way valve 8 is arranged on the high-pressure pipeline, the low-pressure air pump connector is directly connected with a low-pressure air pump 9 through a high-pressure output one-way valve 10, the low-pressure air pump and the valve plate are assembled into an integrated structure, a pressure sensor 11 is arranged on the detection port, and the high-pressure air pump, the low-pressure air pump and the pressure sensor are all connected with a control module 12. Typically, the control module includes an ECU electronic controller unit. After the inflation system is started, the low-pressure pump works first, after the low-pressure pump is inflated to a low-pressure limit value (namely, the parameter set by the ECU), the low-pressure pump stops working, the low-pressure one-way valve is closed, the high-pressure pump starts working at the same time, and the ECU controls the pump to regulate the speed according to the local altitude, the inflation to the pressure limit value and the limit value of the pressure rising rate.
The output ends of the high-pressure air pump and the low-pressure air pump are connected to the valve plate and are provided with one-way valves for outputting to the cavity of the valve plate, gas firstly passes through the valve plate when the low-pressure pump works, the pressure sensor on the valve plate can detect the gas pressure and outputs the gas through the gas outlet, when the pressure reaches the low-pressure output pressure limit value, the ECU controls the low-pressure pump to stop working, the output one-way valve of the low-pressure air pump is closed and simultaneously starts the high-pressure pump to work, the pressure sensor in the valve plate detects the gas pressure and the pressure rising rate, and when the high-pressure pump reaches the inflation limit value, the high-pressure pump stops working, and the high-pressure output one-way valve is closed.
The high-pressure air pump and the low-pressure air pump are arranged on the same side of the valve plate, and the air inlet side corresponds to the air outlet side, so that the structure arrangement is very convenient. The high-pressure pipeline adopts a rubber pipeline. The air outlet is arranged on one side of the valve plate, which is different from the air inlet. And an air supply pipe connector is arranged on the air outlet. The middle part of the valve plate is provided with the air inlet cavity, the air inlet and the air outlet are both axially perpendicular to the air inlet cavity, the detection port is arranged at the tail end of the air inlet cavity and communicated with the air inlet cavity, and the pressure sensor is not directly blown by air flow of the air inlet, so that the working is stable and the reliability is high.
In order to ensure the comfort of wounded, the pressure rise rate in the cabin can be controlled according to the requirement, when the wounded enters the cabin, the pressure rise rate is generally controlled to be about 3 meters/second, the cabin body is not filled in the initial state, the high-flow (low-pressure pump full load) operation can be realized, and after the cabin body is filled, the pressure rise rate of 3 meters/second is observed to operate; therefore, the motors of the high-pressure air pump and the low-pressure air pump are all motors with more sensitive speed regulation function. When the air pump is selected, the model which can be started by one key is preferably adopted, the low-pressure pump is firstly used for high-flow low-pressure inflation of the cabin body (and obeys the pressure rise rate limitation controlled by the ECU), and the output gas of the low-pressure pump is output through the inflation valve plate; the pressure sensor in the charge valve plate senses the output gas pressure and the rate of pressure rise at this time.

The performance of the pump meets the characteristics of 500L/min output of the maximum flow below 5kPa at low pressure and about 20L/min output of the small flow of 40kPa at high pressure, and overcomes the defects that a single pump source needs 500L/min of large flow and 40kPa of large volume and heavy weight.
When the pressure reaches a low pressure set value, the low pressure pump automatically stops working, and the low pressure output one-way valve is closed; meanwhile, the high-pressure pump starts to work, at the moment, a pressure sensor in the inflation valve plate collects and outputs a pressure signal to an electronic control unit ECU, the electronic control unit calculates inflation pressure according to the local altitude, and the high-pressure pump is inflated for the full load or partial load of the cabin while keeping compliance with the limitation of the pressure rising rate, and stops working when the pressure of the high-pressure pump reaches a set value corresponding to the local altitude; when the cabin needs to be ventilated, the system can open a cabin ventilation valve, and meanwhile, the high-pressure pump can also receive an instruction of the electric control unit to start up to supplement air for the cabin.
