Pipeline pre-filling circulation device special for ECMO and application of device

Abstract

The invention discloses a pipeline pre-filling circulation device special for ECMO and application of the device. The pre-filling circulation device comprises an infusion bag pre-filled with normal saline, the bottom of the infusion bag is provided with two pre-filling liquid ports, a heparin capsule containing a heparin sodium medicine solution is arranged between the two pre-filling liquid ports, and a channel is formed between the heparin capsule and the infusion bag and internally provided with blocking thin film, and the distance between the two pre-filling liquid ports is 6-8 cm; the pre-filling circulation device can avoid liquid emptying caused by using a liquid transfer bag, shorten the pipeline pre-filling time and increase the primary pre-filling success rate of the ECOM.

Description

technical field [0001] This application relates to the field of medical devices, in particular to a high-efficiency ECMO dedicated pipeline priming cycle device and its application. Background technique [0002] Extracorporeal membrane oxygenation (ECMO) is a respiratory and circulatory support technology. Its principle is to drain the patient's venous blood out of the body through a centrifugal pump, and through the gas exchange of the artificial lung (oxygenator), make the venous blood Oxygenated into arterial blood, and then reinfused into the body to replace the heart and lungs. As one of the extracorporeal life support technologies, it was early applied to patients with difficulties in weaning off the extracorporeal circulation and low cardiac output syndrome after cardiac surgery. The application sites are mainly Operating room: In recent years, because ECMO has effectively helped critically ill patients through the fatal danger period and gained time for follow-up tre...

Problems solved by technology

[0008] Clinically, there are two pre-filled exhaust pipes, A and B (attached image 3 ), the upper end of the exhaust pipe A is connected to the liquid transfer bag, the lower end is connected to the three-way switch of the circulation pipe (close to the far end of the centrifugal pump head), the needle of the pre-filled exhaust pipe B is inserted into the mouth of the pre-filled liquid bag, and the other end is connected to the three-way switch of the circulation pipe. Turn on the switch (near the end of the centrifugal pump head), close the two pre-filled exhaust pipes with pipe clamps, and adjust the flow knob to 2000r / h (flow rate > 1.0L / min) after starting the machine and zeroing. Pre-filling under the speed or flow rate requires the operator to clamp the pre-filling exhaust pipe B when the liquid in the pre-filling bag is about to be delivered to prevent the liquid from emptying and stop the machine. Transfer the other infusion port of the bag to form the circulation of the liquid in the bag. This operation often empties the liquid and causes air to enter the pipeline and the centrifugal pump head, resulting in the failure of the first prefill, and the need to repeatedly switch the machine, resulting in prefill time. Prolonged, seriously affecting the patient's ECMO machine support treatment time
