1. An abdominal cavity balloon for preventing a haemorrhage in a patient’s pelvic region, comprising:
an inflatable balloon, said balloon comprising a smooth surface and a strip that is flexurally stiff;
wherein a first end of said strip engages a surface within said balloon for positioning of said balloon and said first end of said strip does not penetrate through said balloon;
wherein a second end of said strip extends in a curve conforming to said balloon and then extends away from said balloon surface; and
wherein during use in the patient’s pelvic region said second end of said strip extends from said balloon to an outside of the patient.
2. An abdominal cavity balloon according to claim 1 wherein said strip comprises channels for the inlet and outlet of an inflating medium for said balloon.
3. An abdominal cavity balloon according to claim 2 wherein said channels for are configured so as to provide the inflating medium individual access to said compartments of said balloon individually.
4. An abdominal cavity balloon according to claim 1 wherein an exterior of said balloon is provided with a coagulation-promoting coating.
5. An abdominal cavity balloon according to claim 1 wherein said balloon comprises partitions for partitioning said balloon into pre-shaped compartments.
6. An abdominal cavity balloon according to claim 5 wherein said balloon comprises first, second, and third compartments and wherein said strip engages a surface of said first, second, and third compartments.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A receiving circuit of a DSRC radio, comprising:
a radio unit for receiving a radio signal having a frame configuration containing a unique word (UW), and distributing the signal to a plurality of subsequent systems;
a plurality of UW detection units for detecting a UW signal from an output signal from said radio unit;
a determination unit for receiving a UW detection signal output by said UW detection units, determining a UW detection unit indicating a better detection state, and outputting a determination signal for identifying a UW detection unit indicating a better detection state; and
a switch unit for selecting and outputting an output signal of said plurality of UW detection units according to the determination signal.
2. A receiving circuit of a DSRC radio, comprising:
a radio unit for receiving a radio signal transmitted after split-phase-coding and ASK-modulating a signal comprising an NRZ code sequence forming a frame in the order of a PR signal, UW signal, data, and a CRC signal, ASK-detecting the signal, and generating an ASK detection signal;
a buffer unit for performing a re-timing process on said ASK detection signal using a clock provided by an oscillation unit, and generating a base band signal;
a first and a second split phase decoding unit for decoding said base band signal into an NRZ signal;
a first and a second clock regeneration unit for regenerating a clock of the base band signal from the base band signal and a clock output by said oscillation unit, generating a first and a second regenerated clock signal having different phases, and providing the signals as clocks of said first and second split phase decoding units;
a first and a second UW detection unit for detecting the UW signal from the NRZ signal output by said first and second split phase decoding units;
a determination unit for comparing the UW signals detected by said first and second UW detection units, and determining the UW signal indicating a better detection result;
a logical sum unit for obtaining a logical sum of a detected timing signal of the UW signals detected by said first and second UW detection units;
a data analysis unit for analyzing the data using the selected UW signal, the data, the CRC signal, and the detected timing signal; and
a control unit for controlling said first and second clock regeneration units according to an output signal of said determination unit such that phases of the first and second regenerated clocks can be different from each other.
3. The circuit according to claim 2, wherein said control unit changes a phase of at least one of the clocks regenerated by controlling said first and second clock regeneration units based on a determination result of the UW signal detection result determined by said determination unit.
