Description

Cold compress's pressing component and use its hemostasis device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a cold compress pressing assembly and a hemostasis device applying the same.

Background

In clinical work, a blood sample of a patient is collected through venipuncture or medicines are infused into the body of the patient through venipuncture for the purpose of treating diseases, and therefore, venipuncture is one of the most common operations in clinical work. After venipuncture is finished, the puncture part needs to be pressed for hemostasis, a common method is that a patient presses the puncture part by a cotton swab, and the patient often bleeds again or subcutaneous extravasated blood at the puncture part because the pressing method is incorrect or the pressing time is insufficient; particularly, when the nurse needs to puncture again after the first venipuncture fails, the patient needs to press to stop bleeding and to puncture again at another place. If the patient does not have the assistance of other people, the patient has no way to press; even when other persons assist in compression hemostasis, the risk of infection of the compression person, particularly through blood-borne diseases, is increased.
