Abstract

The present invention relates to a femoral compression system (14) for applying compression against a puncture site of a vessel in a patient, and a method for applying compression with a femoral compression system. The compression system (14) comprises an inflatable compression element (15) adapted to apply a pressure against the puncture site, a tightening unit (23) adapted to extend around a part of, or the whole of, the patients body to fixate and to tighten the compression element (15) against the puncture site, a pump (16) adapted to inflate the compression element (15), a valve (17) adapted to deflate the compression element (15), a pressure transducer (18) adapted to sense the pressure within the compression element (15). The system further comprises a blood pressure pulse detector (19) adapted to sense the patient'"'"'s blood pressure pulse and to generate a pulse signal in dependence thereto that is applied to a control unit (20) that is connected to the pump (16), valve (17) and pressure transducer (19), wherein the control unit (20) is adapted to control the pressure within the compression element (15) in dependence of the pulse signal, by applying control signals to said pump (16) and valve (17).

Claims

1. A femoral compression system (14) for applying compression against a puncture site of a vessel in a patient, comprising:

an inflatable compression element (15) adapted to apply a pressure against said puncture site;

a tightening unit (23) adapted to extend around a part of, or the whole of, the patients body to fixate and to tighten the compression element (15) against said puncture site;

a pump (16) adapted to inflate said compression element (15);

a valve (17) adapted to deflate said compression element (15);

a pressure transducer (18) adapted to sense the pressure within said compression element (15);

characterized in that said system (14) further comprises a blood pressure pulse detector (19) adapted to sense the patient'"'"'s blood pressure pulse and to generate a pulse signal in dependence thereto that is applied to a control unit (20) that is connected to said pump (16), valve (17) and pressure transducer (18), wherein said control unit (20) is adapted to control the pressure within said compression element (15) in dependence of said pulse signal, by applying control signals to said pump (16) and valve (17).

2. A compression system according to claim 1, wherein said control unit (20) is adapted to control the pressure within said compression element (15) in accordance to one of many predetermined compression schedules.

3. A compression system according to claim 2, wherein said compression schedules comprises max/min thresholds of the detected pulse.

4. A compression system according to claim 2, wherein said compression schedules comprises control parameters, such as response times, and/or max/min inflated pressure.

5. A compression system according to claim 2, wherein each compression schedule is set up with regard to different patient types.

6. A compression system according to claim 1, wherein said compression element (15) is adapted to be inflated until the pulse is no longer registrated by the pulse detector (19).

7. A compression system according to claim 6, wherein said compression element (15) further is adapted to be deflated until the pulse detector (19) registrates the pulse again.

8. A compression system according to claim 1, wherein said control unit (20) is wirelessly connected to said pulse detector (19), said pressure transducer (18) and said pump (16) and valve (17).

9. A compression system according to claim 1, wherein said pulse detector (19) is a pedal pulse detector.
