Abstract

The invention relates to a device for performing hemostasis at two symmetrically located puncture sites in the femoral arteries or veins of a patient. It comprises a beam member (6, 8) provided with two attachment devices (10, 12) for pressure pads. There are belts for securing the device to the patient to provide a pressure on the puncture sites, and means (18, 20, 24, 26) for adjusting the distance between said attachment. The invention also provides a method of controlled hemostasis at two puncture sites in each femoral artery or vein of a patient after catheterization, comprising providing a beam member having two pressure pads, adapted to bear against each puncture site, adjusting the center-to-center distance of said pressure pads by moving at least one of said pressure pads along said beam member, applying said pressure pads at said puncture sites, securing said beam member carrying said pressure pads to the body of said patient, by tightening a belt around the body.

Claims

1. A device for performing hemostasis at two symmetrically located puncture sites in the femoral artery or veins of a patient, comprising

a beam member (6, 8;

32, 34;

50;

110;

126, 128);

two attachement means (10, 12;

52, 54;

116, 118;

122, 124) for attaching pressure pads, provided on said beam member;

means for securing the device to a patient to provide a pressure on the puncture sites;

characterized in that

the attachment means are located essentially in the same plane; and

in that

there are provided means for adjusting the distance between said attachment means along said beam member (6, 8;

32, 34;

50;

110;

126, 128) to correspond to the distance between the puncture sites such that the pressure pads accurately bear against the puncture sites, at essentially right angles with respect to the plane in which the punctures are located, and such that the forces acting on each respective puncture site are essentially parallel to each other.

2. The device of claim 1, wherein said beam member (6, 8;

32, 34) is provided with attachment means (10, 12) integral with said beam member for securing two pressure pads thereon.

3. The device of claim 2, wherein said beam member comprises two halves (6, 8), each carrying one attachment means (10, 12), and connected to each other by a distance adjustment member (18;

28) providing for said variable distance.

4. The device of claim 3, wherein said distance adjustment member is an elongated element (18) comprising a recessed portion (20), and wherein each beam half comprises a protruding element (24) mating with said recess such that each beam half is slideable in and along said recess, and wherein each beam half is provided with tightening means (24, 26) for fixing thereof at a selected position in said recess.

5. The device of claim 4, wherein said tightening members comprise a screw and nut (24, 26), said screw also forming said protruding element.

6. The device of claim 3, wherein said distance adjustment member (28) comprises a beam receiving compartment, in which a free end of each said beam half is insertable, said free ends being adapted to fit inside each other in a sliding relationship, said distance adjustment member (28) being provided with tightening means (48, 44) for securing said beam halves in a selected position in said beam receiving space.

7. The device of claim 1, wherein one of said attachment means (52) is integral with said beam member (50), and one attachment means (54) is provided on a separate item (60) connectable at a selectable position on said beam member (50).

8. The device of claim 7, wherein said beam member (50) is asymmetric in that one portion thereof extending from said integral attachment means is longer than the other portion, said beam comprising elongated fastening means (70) extending along said beam, and wherein said separate item comprises locking means (64, 66) mating with said fastening means to insure a secure attachment of said separate item.

9. The device of claim 8, wherein said beam has an arc shape and wherein said separate item comprises positioning means mating with selected portions of said arc shaped beam, such that the separate attachment means is secured in a fixed position on said beam when said locking means engage said fastening means.

10. Adapter means, usable as a separate attachment device for a pressure pad on an asymmetric femoral compression device as claimed in claim 7, with one integral attachment means for a pressure pad, said adapter comprising an attachment means (54;

80) for a pressure pad, and means (64, 66, 68, 72;

84, 88, 98) for attaching the adapter at a selected position on said femoral compression device, such as to provided a second attachment means for a pressure pad on said femoral compression device, to render it usable for treating two punctures at one time.

11. The adapter as claimed in claim 10, comprising a connector structure (62) having an essentially T-shaped base portion (68), on the bottom side of which said pressure pad attachment means (54) is mounted, said connector structure (62) being provided with means in the form of latch or hook means (64) provided on two parallel legs (66) extending vertically from the upper side of the base portion (68) of the connector structure (62) for securing it to the beam structure (50).

12. The adapter as claimed in claim 11, wherein the connector structure further comprises two horizontal, flat legs (72), having their wide dimension in the vertical direction, and adapted to engage with the outermost edge portions (23) of belt attachment means (22) provided on said beam structure (50), said legs being provided with recesses (74) on the inner sides thereof providing a guiding function for the beam member.

13. The adapter as claimed in claim 10, comprising two vertical legs (82, 84) extending in a vertical direction from said attachment means (80), at the periphery thereof, the legs being provided with latches or hooks (86, 88) adapted to engage with the side walls of the beam structure of said femoral compression device.

14. The adapter as claimed in claim 13, comprising a support member (90) mounted at the periphery of the attachment means, opposite to where the legs are provided, and extending in the same vertical direction as the legs (82, 84), and being adapted to rest against the upper surface of the beam structure, thereby providing stability to the adapter means.

16. The method of claim 11, wherein said beam member comprises attachment means for said pressure pads.

15. A method of controlled hemostasis at two puncture sites in each femoral artery or vein of a patient after catheterization, comprising:

a) providing an essentially linear beam member having two pressure pads, adapted to bear against each puncture site;

b) adjusting the center-to-center distance of said pressure pads by moving at least one of said pressure pads along said beam member;

c) applying said pressure pads at said puncture sites;

d) securing said beam member carrying said pressure pads to the body of said patient, by tightening a belt around the body.
