Technical Field

[0001] The utility model relates to the technical field of compression hemostasis, in particular to a pressing structure for a hemostatic compressor. Background Art

[0002] Hemostatic compression devices are widely used in medical surgery and rescue. Tourniquets can not only reduce bleeding from the affected area and prevent a drop in blood pressure, but also ensure a clear surgical field of view, facilitate the surgeon's surgical operation, shorten the operation time, reduce the patient's surgical pain, and provide favorable conditions for the patient's postoperative recovery.

[0003] However, the hemostatic compressor is required to be able to generate a large pressure. The conventional hemostatic compressor cannot provide a large pressure and requires medical staff to use their knee joints to resist it, which is time-consuming and labor-intensive and increases the labor intensity of medical staff. In addition, there is no protection around the pressing area, which causes muscle damage to the muscles around the pressing area due to squeezing. Therefore, a pressing structure for a hemostatic compressor is proposed. Utility Model Content
