## Abstract

Pneumatic and therapeutic compression systems are disclosed including treatment protocols that may be used with such systems. A pneumatic compression system may include a source and sink of a pressurizing fluid. The pressurizing fluid may be sourced to a number of valves, each valve controllable by a control device including a computing device. The computing device may control each valve separately to allow any one or more of the valves to connect to the fluid source or the fluid sink. The computing device may include one or more therapeutic protocols that may direct one, two, or more valves to switch between fluid sourcing and fluid sinking, substantially simultaneously or in a sequence. A therapeutic compression system may include the pneumatic system in fluid communication with an inflation sleeve composed of multiple cells. Each cell may be inflated or deflated by a valve according to the therapeutic protocol.

## Claims

### Claim 1

A pneumatic compression system comprising:
a source of a pressurized fluid via a source output;
a sink for the pressurized fluid via a sink input;
one or more manifolds, configured to be in fluid communication with one or more of the source output and the sink input;
a plurality of valves, wherein each valve has a cell side and a manifold side, wherein the manifold side of each of the plurality of valves is in fluid communication with at least one manifold, wherein each of the plurality of valves is in a first state when the cell side of the valve is in fluid communication with the source output, wherein each of the plurality of valves is in a second state when the cell side of the valve is in fluid communication with the sink input, and wherein each of the plurality of valves is in a third state when the cell side of the valve is not in fluid communication with either the source output or the sink input;
a plurality of cell sensors, wherein each cell sensor is in operable communication with the cell side of at least one of the plurality of valves;
a computing device in operable communication with each of the plurality of cell sensors and each of the plurality of valves;
a non-transitory, computer-readable storage medium in operable communication with the computing device;
an input device in operable communication with the computing device; and
an output device in operable communication with the computing device,
wherein the computer-readable storage medium contains one or more programming instructions that, when executed, cause the computing device to:
receive, from the input device, an input related to a therapeutic protocol,
place at least two of the plurality of valves into the first state for a period of time based at least in part on the therapeutic protocol,
receive cell sensor data from at least one cell sensor, and
transmit, to the output device, an output related to the data from the at least one cell sensor,
wherein the therapeutic protocol comprises one or more valve activation times, wherein each of the valve activation times is directed toward the activation of at least two valves.
