Universal connecting device that designates an operational mode
View Patent ↗A controller for a gradient sequential compression system is provided for inflating a plurality of inflatable chambers of one or more compression sleeves according to several different modes of operation. A mode of operation may define the number and selection of chambers to be inflated, the pressurization levels, the pressurization time, or the sequence of chamber inflation. To enable the controller to automatically perform a designated mode of operation based on the type of compression sleeve connected, a new and improved connecting device is provided. An indicator on an interface connector associates a predetermined mode of operation with the interface connector. A sensor associated with a complementary connector identifies the mode of operation associated with the interface connector. It is contemplated that the universal connecting device can be used for any type of system, not just controllers for a gradient sequential compression system.
1. A therapeutic system for compressing a body of a user by applying compressive forces thereto, comprising:
a first compression sleeve having at least a first inflatable chamber therein and a corresponding inflation tube in communication with the chamber, the first compression sleeve being configured to be positioned so that the chamber compresses a portion of the user's body to perform at least a first mode of compression treatment for the body;
an inflation control unit having supply tubing extending therefrom, including at least first and second supply tubes, and having one or more control valves to control a supply of inflation fluid through the supply tubing, a first of the control valves controlling the supply of inflation fluid through the first supply tube; and
a tubing connector to connect either the first compression sleeve or a second compression sleeve to the supply tubing, the connector being shaped such that the inflation tube corresponding to the first inflatable chamber of the first sleeve is fluidically connectable to the first supply tube such that inflation fluid from the first supply tube is conveyed to the first chamber through the corresponding inflation tube;
wherein the inflation control unit includes controls to control the supply of inflation fluid through the supply tubing in at least a first and a second mode; and
a detector to detect whether the first sleeve is connected to the supply tubing, as opposed to the second, and to indicate the same.
2. The therapeutic system of claim 1 , where the detector identifies a mode of operation associated with the tubing connector mated thereto and provides a signal indicative of the mode of operation to the system such that the system may be automatically configured to the selected mode of operation.
3. The therapeutic system of claim 1 , where each of the first compression sleeve and the second compression sleeve is adapted to perform at least one mode of blood flow treatment of the selected portion of the body, where each mode of treatment has different inflation cycles of pressurized air provided to the inflatable chambers of the sleeves.
4. The therapeutic system of claim 1 , including an indicator operably connected to at least one of the first compression sleeve and the second compression sleeve for designating a predetermined mode of operation corresponding to a mode of blood flow treatment associated with the sleeve.
5. The therapeutic system of claim 4 , where the detector is a Hall effect sensor and the sleeves having an associated magnet for providing a magnetic signal that designates the predetermined mode of operation associated with the sleeve.
6. The therapeutic system of claim 4 , where the detector is an optical sensor and the sleeves having an associated reflector to provide a signal to the optical sensor that designates the predetermined mode of operation associated with the sleeve.
7. The therapeutic system of claim 1 , including an indicator associated with the tubing connector, where the indicator designates the mode of operation associated with the sleeve based on the number of inflation chambers in the sleeve.
