Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more particularly to a cardiology compression hemostasis device. Background Art

[0002] Existing equipment often performs single-point pressing when performing hemostatic pressing on the patient's leg. Although it can achieve the effect of hemostatic pressing, the pressing force is often large and can easily affect other muscle groups around the patient's leg.

[0003] To this end, Chinese patent publication number "CN219048699U" discloses a "postoperative compression hemostasis device." Its main structure includes a lower guard plate, an elastic band disposed between the upper ends of the lower guard plate, a hemostatic protrusion disposed at the bottom of the elastic band, and a bracket disposed between the upper ends of the lower guard plate. This postoperative compression hemostasis device rotates a threaded column by turning a manual knob. The adjustment cylinder, in conjunction with two telescopic rods, drives the compression plate downward to abut against the upper surface of the elastic band, thereby further securing the hemostatic protrusion to the wound surface for compression hemostasis.

[0004] However, when the compression hemostasis device is actually used, the threaded column, drive motor and telescopic rod need to be set perpendicular to the patient's wound, resulting in a relatively high longitudinal height of the device. The longitudinal height will affect the degree of restriction of the patient during activities. The higher the height, the greater the probability of accidental contact, and the more likely secondary injury will occur. Summary of the Invention
