## Abstract

Systems, devices, and methods for monitoring and treating a patient on route to a medical facility are disclosed. The system comprises a critical care unit; at least one patient monitoring device coupled to the critical care unit, wherein the critical care unit obtains physiological data about the patient from each patient monitoring device; at least one patient treatment device coupled to the critical care unit, wherein the critical care unit provides treatment instructions to each patient treatment device; a two way communications device coupled to the critical care unit; and a remote communications terminal in communication with the two way communications device. The critical care unit preferably sends the physiological data to the remote communications terminal and receives the treatment instructions from the remote communications terminal via the two way communications device.

## Claims

### Claim 1

A critical care unit for monitoring and treating a patient on route to a medical facility, comprising:
a foldable housing comprised of a first side and a second side coupled by a single hinge;
at least one of a control module, a ventilator module, a processor module, or a pump module housed in the first side; and
at least one of one or more fluids for a patient or structural components housed in the second side;
wherein the critical care unit has a folded transportation configuration and an unfolded use configuration, wherein, in the use configuration, the critical care unit is adapted to be coupled to and fit entirely underneath a patient transport litter.

### Claim 2 (depends on 1)

The critical care unit of claim 1, the critical care unit further comprising a quick coupling device adapted to attach the system to a patient transport litter.

### Claim 3 (depends on 2)

The critical care unit of claim 2, wherein the coupling device is adjustable to fit different sized liters or be used independent of attachment to any litter.

### Claim 4 (depends on 1)

The critical care unit of claim 1, wherein the critical care unit is adapted to be coupled under the litter without raising the litter off the ground.

### Claim 5 (depends on 1)

The critical care unit of claim 1, wherein the transportation configuration is a wearable configuration.

### Claim 6 (depends on 1)

The critical care unit of claim 1, wherein the critical care unit weighs less than 30 pounds.

### Claim 7 (depends on 1)

The critical care unit of claim 1, wherein the critical care unit provides at least 90% accessibility to the patient.

### Claim 8 (depends on 1)

The critical care unit of claim 1, wherein the first side houses at least one of electronics, a ventilator, a processor, suction pumps, a control panel, a battery, a screen, connectors or ports, and speakers.

### Claim 9 (depends on 1)

The critical care unit of claim 1, further comprising a suction reservoir module isolating bodily fluids from other fluids stored in the device.

### Claim 10 (depends on 1)

The critical care unit of claim 1, wherein the second side houses a fluid module adapted to couple a plurality of fluid containers to the device.

### Claim 11 (depends on 10)
