Abstract
An accessory for a VasoStat™ hemostasis device that locks the plunger within the cylinder through which the plunger travels by restricting disengagement of ratcheted wings affixed to the plunger. The accessory may be repositioned or removed so that the ratcheted wings may be disengaged and the plunger may be retracted within the cylinder. When integrated into the plunger, the accessory may be configured to move between a first unlocked position and a second locked position. As a separate component, the accessory is configured to be positioned over and locked into position on the hemostasis device, such as the central stem of the plunger.
Claims19
A locking hemostasis device for adhering to a patient's skin and applying a compressive force to a puncture site, the device comprising:
- a footplate,
- a receiving device positioned on the footplate,
- a plunger having a top surface wherein the plunger is positioned within the receiving device and configured to move therethrough and apply a compressive force to the patient's skin at the puncture site,
- a plurality of motion restricting components interposed between the receiving device and the plunger to restrict reverse movement of the plunger through the receiving device;
- and
- an elongated tab having a long axis, a top surface, and a bottom surface, wherein the elongated tab is rotatably affixed to the top surface of the plunger and configured to be rotatable between a first unlocked position in which the plurality of motion restricting components are unrestricted from inward movement and a second locked position in which the plurality of motion restricting components are restricted from inward movement.
A locking hemostasis device for adhering to a patient's skin and applying a compressive force to a puncture site, the device comprising:
- a footplate,
- a receiving device positioned on the footplate,
- a plunger having a central stem wherein the plunger is positioned within the receiving device and configured to move therethrough and apply a compressive force to the patient's skin at the puncture site,
- a plurality of motion restricting components interposed between the receiving device and the plunger to restrict reverse movement of the plunger through the receiving device;
- and
- a cylinder comprising a side wall having top edge and an outer surface wherein the cylinder is configured to fit onto the central stem of the plunger and restrict the plurality of motion restricting components from inward movement.
A method for applying a locked compressive force to a patient's skin at the site of a puncture site, the method comprising the steps of:
- placing a hemostasis device on the patient's skin at the site of a puncture site, wherein the hemostasis device comprises a footplate, a receiving device positioned on the footplate, a plunger positioned within the receiving device and configured to move therethrough, a plurality of motion restricting components interposed between the receiving device and the plunger to restrict reverse movement of the plunger through the receiving device, and an elongated tab having a top surface and a bottom surface, wherein the elongated tab is rotatably affixed to the top surface of the plunger and configured to be rotatable between a first unlocked position in which the plurality of motion restricting components are unrestricted from inward movement and a second locked position in which the plurality of motion restricting components are restricted from inward movement;
- advancing the plunger through the receiving device until the plunger applies a compressive force to the puncture site;
- engaging the plurality of motion restricting components to restrict reverse movement of the plunger through the receiving device;
- and
- rotating the elongated tab from the first unlocked position to the second locked position.
