Description

TECHNICAL FIELD

The present invention relates to a chest compression device used for cardiopulmonary resuscitation.

BACKGROUND ART

Cardiopulmonary resuscitation (CPR) is a first aid technique of regularly compressing the heart to circulate blood to the brain when the heart stops beating, thereby preventing brain cell damage. When the heart abruptly stops functioning, leading to a sudden cardiac arrest (SCA), a witness nearby should immediately give first aid by performing CPR. If CPR is not performed, a patient with SCA may be dead or brain dead.

CPR should be continuously repeated until the heart of the cardiac arrest patient beats again. It is not easy for ordinary people to continuously compress the heart of the cardiac arrest patient at a constant rate and at a constant pressure. Even paramedics or medical personnel who got professional training may have a physical difficulty in repeating CPR for a long time to compress the heart of the cardiac arrest patient.

Therefore, it is required to develop a mechanical device capable of compressing the heart of a cardiac arrest patient at a constant rate and at a constant pressure. Currently, Lucas™ portable chest compression devices are commercially available and used.

The conventional portable chest compression device as above is disclosed in Korean Patent Laid-open No. 2006-0009014 and is explained with reference to FIGS. 1 and 2 attached herewith. FIG. 1 is a side view of a conventional chest compression device, and FIG. 2 is a cross-sectional view taken along the line A-A. The device includes a back 2 and a U-shaped support 3. A cardiac arrest patient 1 is straightly laid on his back on the back 2, and then the center of the back 2 is placed below the breastbone S. The back 2 is extended laterally to both sides of the patient. One extension part 23 of the back 2 is connected to one end of the support 3 by a hinge, and a snap lock for storing the other end (free end) of the support 3 is mounted on the other extension part 24 of the back, thereby rapidly fixing the support 3 on the back 2. Accordingly, the chest of the patient 1 is surrounded by the chest compression device. As illustrated in FIG. 2, the chest compression device has a shape similar to a stirrup. The central part of the U-shaped support 3 is positioned, maintaining a distance from the breastbone S.

The central part of the support 3 includes a compression unit. The compression unit includes a compression pad 5 connected to a piston 6 within the same chamber 8, 9 of a cylinder by a rod 7. The rate, distance, pressure, etc. of the reciprocating movement of the piston 6 and the compression pad 5 are controlled by a control unit 13 including a microprocessor. In general, the piston 6 is controlled to perform a vertical reciprocating movement at a constant rate within a range between 60 and 150 strokes per minute.

The device may be driven by a battery (not illustrated) provided therein, or may be driven by an external power source (not illustrated) by being connected to the external power source via a cable (not illustrated).

It is known that about 60-70% of cardiac arrest patients have cardiovascular problems which lead to cardiac arrest. Therefore, when the cardiac arrest patient visits a hospital, the doctor may need to monitor blood vessels of the heart using coronary angiography (pPCI) in order to examine cardiovascular problems.

However, while performing CPR using the conventional chest compression device or performing CPR by a person, the heart is hidden by the chest compression device or the person performing CPR, and thus cardiovascular images cannot be obtained using coronary angiography.
