Abstract
Femoral compression device including a pressurizing element for compressive bearing at the puncture site, preferably located at the femoral artery of a patient subjected to, for example, heart catheterization, and for applying a pressure on the same, and a base plate for supporting the pressurizing element. A belt is adapted to be fixed around the patient's body. The base plate has a top portion and a bottom portion and is adapted to be fixed to the belt and the pressurizing element is provided at the bottom portion of the base plate so as to exert a compressive force against the patient's body at the puncture site.
Claims25
Femoral compression device comprising:
- (a) a pressurizing means for compressive bearing at a puncture site at a femoral artery of a patient, and for applying a pressure on the puncture site, having a transparent portion to permit viewing of the puncture site;
- (b) a belt adapted to be fixed around the patient's body;
- and
- (c) a base plate supporting the pressurizing means, including a top portion having a plurality of extensions, including first and second extensions extending in opposite directions, disposed at an elevated position in relation to the top portion of the base plate, and provided with locking means in the ends thereof for insertion of an end of the belt;
- a bottom portion connected to the pressurizing means;
- the base plate having a transparent portion to permit viewing of the puncture site.
Method for achieving hemostasis of the femoral artery of a patient, comprising the steps of:
- applying a reference pressure over a puncture site in the femoral artery;
- applying an additional pressure over the puncture site;
- monitoring a sum of the reference pressure and the additional pressure;
- gradually reducing the additional pressure;
- and
- releasing the reference pressure when the hemostasis is fully completed;
- wherein the monitoring step further comprises registering a plurality of pulsation values caused by the patient's pulse at the puncture site, comparing the pulsation values with selected values, and controlling the additional pressure dependent on the pulsation values.
Method for achieving hemostasis of the femoral artery of a patient, comprising the steps of:
- applying a reference pressure over a puncture site in the femoral artery;
- applying an additional pressure over the puncture site;
- monitoring a sum of the reference pressure and the additional pressure;
- gradually reducing the additional pressure;
- and
- releasing the reference pressure when the hemostasis is fully completed;
- wherein the monitoring step further comprises registering a plurality of actual blood pressure values at or downstream of the puncture site, comparing the blood pressure values with a plurality of selected values, and controlling the additional pressure dependent on the blood pressure values.
Method for achieving hemostasis of the femoral artery of a patient, comprising the steps of:
- applying a reference pressure over a puncture site in the femoral artery;
- applying an additional pressure over the puncture site;
- monitoring a sum of the reference pressure and the additional pressure;
- gradually reducing the additional pressure;
- releasing the reference pressure when the hemostasis is fully completed;
- and
- selecting and programming selected pressure values and times into an electronic control unit, and sequentially applying different pressures on the artery in accordance with the pressure values.
