Description

Heart compression device

Technical Field

The utility model relates to the technical field of medical treatment, in particular to a heart compression device.

Background technique

Cardiac arrest refers to the sudden cessation of heart beating due to various reasons in unexpected circumstances and time, resulting in the sudden cessation of effective cardiac pumping function and effective circulation. If correct and effective resuscitation measures are taken in time, the patient may be saved and recover.
