Description

{A device for body fluid receiving of extracorporeal membrane oxygenation}

The present invention relates to a body fluid receiving device for ECMO, and more specifically, an ECMO device that can be applied to ECMO treatment patients and minimize the contact of the received body fluid with air, thereby minimizing the bleeding risk, surgical time, and cost that occur during extracorporeal circulation surgery. It relates to a body fluid receiving device for hair.

In general, cardiopulmonary circulatory assist devices are devices that assist the function of the heart or lungs when their function deteriorates or stops, including ECLS (ExtraCorporeal Life Support), CPB (CardioPulmonary Bypass), VAD (Ventricular Assist Device), and ECMO. (Extracorporeal Membrane Oxygenation), etc.

Among them, ECMO (Extracorporeal Membrane Oxygenation) is an extracorporeal membrane oxygen supply device that is placed outside the body to circulate blood, supply oxygen to the circulating blood, and then introduce it back into the body to assist cardiopulmonary function. It consists of a pump that circulates blood and an oxidizer that is connected to the pump and supplies oxygen to the blood circulating through the pump.

However, conventional ECMO did not have a device for receiving or storing body fluids, making it difficult to control the blood flow of ECMO patients.

To solve this problem, venous blood reservoirs and cardiotomy blood reservoirs have been developed and increased in recent years, but their functionality is limited to the cardiopulmonary bypass circuit, so a complicated installation process is required for ECMO treatment patients to use them. There were various limitations, including the mandatory requirement.

In particular, in order to perform extracorporeal circulation surgery for ECMO treatment patients, 1) removal of the ECMO circuit, 2) installation of a surgical extracorporeal circulation circuit, 3) priming of a surgical heart-lung machine, 4) operation of a surgical heart-lung machine, 5) hard shell. As a total of 8 sequential steps were required: reserve bag priming, 6) patient blood extraction, 7) hard shell reserve bag blood reception, and 8) ECMO circuit reinstallation, during the patient's surgical preparation process. There was a problem that it took a considerable amount of time.

In particular, among the steps taken to perform the above-mentioned extracorporeal circulation surgery, 5) the hard shell reserve bag priming step took a considerable amount of time, and more specifically, at least an hour was required.

At this time, the hard shell reserve bag is used as a venous blood reservoir and a heart incision blood reservoir. The hard shell reserve bag is mostly made of a hard material body, and the priming process of the reservoir itself, that is, the operation of removing the air remaining inside the hard shell reserve bag, is performed. It is required, and in this priming process, there is a problem that it takes a lot of time to fill the hard shell reservoir bag with a priming solution to remove the air, and at the same time, there is a problem that the cost of surgery also increases as the time required increases. there is.

Therefore, when performing extracorporeal circulation surgery for patients undergoing ECMO treatment, there is a need for a means of receiving body fluid that can reduce the time required to prepare the patient for surgery, enable rapid surgery, and reduce costs at the same time. am.

In addition, even during the use of a commonly used hard shell reserve bag after installation of the ECMO circuit for a conventional surgery, the hard shell reserve bag is made of a hard material that does not deform in shape, so an empty space is essentially formed inside. Due to the empty space, contact of the body fluids contained in the hard shell reserve bag with air was inevitable, so there was also a problem that a certain amount of heparin was required to be injected.

In addition, there are concerns that the patient's blood may become diluted due to excessive injection of heparin, leading to bleeding risks and complications during surgery. Therefore, a means of containing body fluids that can minimize contact of body fluids and blood with air is needed. It is desperately needed.
