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 for applying compression against a puncture site of a vessel in a patient, comprising:

an inflatable compression element configured to apply a pressure against said puncture site;

a belt configured to extend around a part of, or the whole of, the patient'"'"'s body to fixate and to tighten the compression element against said puncture site;

a pump configured to inflate said compression element;

a valve configured to deflate said compression element;

a pressure transducer configured to sense a pressure within said compression element and generate a pressure signal indicative of the pressure within said compression element;

a blood pressure pulse detector configured to sense the patient'"'"'s blood pressure pulse and to generate a pulse signal based on the patient'"'"'s blood pressure pulse; and

a control unit configured to;

(i) receive the pressure signal from the pressure transducer, (ii) receive the pulse signal from the blood pressure pulse detector, (iii) control operation of the pump, and (iv) control operation of the valve,

wherein, during operation of the compression system, the control unit controls the pressure within said compression element in accordance with a predetermined compression schedule, such that the control unit (i) controls the pump to inflate the compression element to a first elevated pressure at which the pulse signal indicates that no pulse is detected by the blood pressure pulse detector, (ii) maintains a pressure of the compression element at the first elevated pressure for a first duration, which is in a range of one to three minutes, (iii) after the first duration, controls the valve to deflate the compression element to a second elevated pressure at which the pulse signal indicates that a pulse is detected, (iv) maintains a pressure of the compression element at the second elevated pressure for a second duration that is longer than the first duration, and (v) after the second duration, controls the valve to further deflate the compression element.

2. The compression system according to claim 1, wherein said compression schedule comprises a maximum threshold of the detected pulse and a minimum threshold of the detected pulse.

3. The compression system according to claim 1, wherein said compression schedule is selected from a plurality of compression schedules that are stored in the control unit, each of the plurality of compression schedules being based on a different patient type.

4. The compression system according to claim 1, wherein said control unit is wirelessly connected to said pulse detector, said pressure transducer, said pump, and said valve.

5. The compression system according to claim 1, wherein said pulse detector is a pedal pulse detector.

6. The compression system according to claim 1, further comprising an inflatable cuff, wherein said pulse detector is arranged in relation to the inflatable cuff.

7. The compression system according to claim 1, wherein said control unit comprises an indicator unit adapted to indicate to an operator when it is time to deflate said compression element.

8. The compression system according to claim 1, wherein said compression schedule comprises a maximum inflated pressure and a minimum inflated pressure for the compression element.

9. The compression system according to claim 1, wherein, when the control unit controls the valve to further deflate the compression element, the control unit controls the valve to incrementally deflate the compression element.

10. The compression system according to claim 1, wherein the second duration is about 15 minutes.
