Abstract

The invention provides a femoral compression device (11; 21) for compressing a femoral artery of a patient. The femoral compression device (11; 21) comprises a pressurizing means (12; 22), a compression plate (13; 23) for compressive bearing against a puncture site, a base portion (14; 24) provided with two opposing extensions (15, 16; 25, 26), to the ends of which a belt, which is adapted to be arranged around the patient'"'"'s body, can be fixed. According to the invention, the pressurizing means is in the form of a spring (12; 22), such as a coil spring (12; 22), the first end of which is connected to the compression plate (13; 23) and the second end of which is operatively connected to a handle (19; 29), which can be operated to adjusting the compression of the spring (12; 22).

Claims

1. A femoral compression device for compressing a femoral artery of a patient, comprising a spring, a compression plate for compressive bearing against a puncture site, and a base portion provided with two opposing extensions, to the ends of which a belt, which is adapted to be arranged around the patient'"'"'s body, can be fixed.

2. A femoral compression device according to claim 1, wherein a first end of the spring is connected to the compression plate and the second end of the spring is operatively connected to a handle, which can be operated to adjust the compression of the spring.

3. A femoral compression device according to claim 1, wherein the femoral compression device is provided with a gauge that indicates the amount of compression pressure being applied against the puncture site.

4. A femoral compression device according to claim 3, wherein the gauge indicates the compression of the spring.

5. A femoral compression device according to claim 1, wherein the first end of the spring is connected to the compression plate and the spring, together with an adjusting screw, is provided in a housing, the upper end of the adjusting screw being connected to a handle and the adjusting screw being threaded through a washer, which bears against the second end of the spring, so that, by turning the handle, the washer moves along the adjusting screw to thereby adjust the compression of the spring.

6. A femoral compression device according to claim 5, wherein the compression plate is provided with a measuring rod that extends through the washer, which measuring rod indicates the distance from the compression plate to the washer and thereby the compression of the spring.

7. A femoral compression device according to claim 1, wherein the first end of the spring is connected to the compression plate, the spring extends through the base portion and at least partly into one of the extensions, and the second end of the spring is connected to a handle, which is slidable along said extension and which is lockable at a desired position, so that the compression of the spring can be adjusted by moving the handle.

8. A femoral compression device according to claim 7, wherein the compression plate is provided with a guide rod that extends into a corresponding guide hole provided in the base portion.

9. A femoral compression device according to claim 7, wherein the compression plate is provided with a measuring rod that extends into the extension in which the spring is arranged, which measuring rod indicates the distance from the compression plate to the handle and thereby the compression of the spring.

10. A femoral compression device according to claim 2, wherein the femoral compression device is provided with a gauge that indicates the amount of compression pressure being applied against the puncture site.

11. A femoral compression device according to claim 1, wherein the spring comprises a coil spring.

12. A femoral compression device according to claim 3, wherein the gauge indicates the amount of compression pressure being applied against the puncture site in mmHg.

13. A femoral compression device according to claim 1, wherein the spring comprises a leaf spring.

14. A femoral compression device according to claim 1, wherein the spring comprises a laminated spring.

15. A femoral compression device according to claim 1, wherein the spring is made from plastic.

16. A femoral compression device according to claim 1, wherein the spring is made from metal.

17. A femoral compression device according to claim 1, wherein the spring is made from Nitinol.

18. A femoral compression device according to claim 1, wherein the spring is made from an alloy.
