Description

  The present invention relates to an external defibrillator.

  For example, for patients whose heart has ventricular fibrillation and can no longer send blood to the whole body, an external defibrillation that attempts to remove the heart fibrillation by applying an electric shock to restore normal heart movement Motivation is known.

For example, as shown in Patent Document 1, the external defibrillator includes an extracorporeal paddle and a defibrillator body that applies an electric shock to the patient via the extracorporeal paddle applied to the body surface.
A cable is led out from the extracorporeal paddle, and a connector is provided at an end of the cable. By inserting this connector into the defibrillator body, the extracorporeal paddle is electrically connected to the defibrillator body.
The defibrillator body performs a defibrillation process by applying an electric shock to the patient via the extracorporeal paddle by an operation with the extracorporeal paddle. The defibrillator body can acquire information (electrocardiogram ECG: Electrocardiogram) related to the patient's heart state through the extracorporeal paddle. In this defibrillator main body, a display surface for displaying information necessary for defibrillation is disposed on one side surface, and an accommodating portion for accommodating an extracorporeal paddle is formed on the upper surface.

  As an external defibrillator that accommodates extracorporeal paddles on the upper surface of the defibrillator main body, the upper surface of the defibrillator main body can be carried to the emergency site by the defibrillator and moved with the patient. In addition, a configuration is known in which a handle (main body handle portion) protruding upward is provided. The main body handle part is formed by bridging a gripping part to be gripped by a hand between arms protruded away from the upper surface of the defibrillator body, and this gripping part is at a high position and defibrillation is performed. It should be positioned close to the vertical line that passes through the center of gravity of the container body, making it easy to carry. Specifically, as shown in FIG. 1 of Patent Document 2, the main body handle portion is a portion between the housing portion of the extracorporeal paddle and the display surface with the display (display portion) on the upper surface of the defibrillator main body. (The part where the cord is arranged) and projecting upward so that the gripping part is located at a high position.
