2. Description of the Related Art Conventionally, chest compression patients are generally used for resuscitation of cardiac arrest patients. There is no doubt about the effectiveness and importance of the cardiac massage method, but this resuscitation method has an uncertain blood supply to the brain, so that recovery of cerebral blood flow is poor even if the heart beat is restarted. Brain death or becoming a plant human was by no means uncommon. Therefore, effective recirculation of blood is an essential requirement for resuscitation of cardiac arrest patients, especially for brain resuscitation. For that purpose, extracorporeal circulation of blood is effective, and it has been proved in many cases. This extracorporeal circulation method (venous / arterial bypass method) forms a bypass circuit that connects veins and arteries outside the body to circulate blood extracorporeally, remove carbon dioxide from venous blood, and add oxygen (gas exchange). The device is equipped with an oxygenator for gas exchange of blood and a pump device for circulating blood.

However, the above-mentioned prior art also has room for improvement in the following aspects. In other words, the venous / arterial bypass method is a method of circulating blood outside the body, that is, venous blood once flowing out of the body and sending to the arterial side for circulation. It is preferable that the amount of the inhalation of the pump, in particular, the inhalation amount of the pump is differentiated according to the weight of the patient, the adult, the child, etc. Especially in the case of children and infants, there is a risk of adverse effects if the amount of inhalation of each pump is not carefully adjusted and applied. However, in the pump device of the prior art, since the volume of the elastic bag is constant,
There was a problem that the amount of blood inhaled and discharged could not be changed.

With the manual pump device for extracorporeal circulation configured as described above, when the elastic bag is pressed, the valve on the liquid inlet side of the bag closes and the valve on the liquid inlet side opens, so that the liquid in the storage chamber is not pumped. It is delivered (discharged) from the liquid port and supplied to a predetermined portion. When the bag is released from compression, the bag self-expands (at this time, the valve on the liquid delivery side of the bag closes and the valve on the suction side of the bag opens), causing a vacuum (negative pressure) state in the accumulation chamber. , The amount of liquid corresponding to the delivered amount is sucked into the chamber through the liquid suction port. Therefore, liquid (blood) can be circulated in a predetermined direction by repeatedly pressing the bag. On the other hand, when air or liquid is introduced into the closed chamber of the variable volume body from the connection passage, the variable volume body expands and the volume increases, and when the air or liquid is discharged from the closed chamber, the variable volume body contracts. Volume is reduced. Since the volume of the accumulating chamber of the bag is constant, the liquid receiving volume of the accumulating chamber is changed by changing the volume of the variable volume body as described above. Therefore, by changing the volume of the variable body, the suction / discharge amount of the liquid per one time of the pump changes.
