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 s

Embodiment 1

[0027] Example 1 ECMO dedicated pipeline pre-filling circulation device

[0028] The structure of the ECMO dedicated pipeline pre-filling circulation device provided in this embodiment is as follows: figure 2 Shown: a pre-filled circulation device dedicated to ECMO, including an infusion bag 1 pre-filled with normal saline, and two pre-filled ports are provided at the bottom of the infusion bag, namely port A2 and port B3, between port A2 and port B3 A heparin capsule 4 containing heparin sodium medicinal liquid is provided, a channel is provided between the heparin capsule 4 and the infusion bag 1, and a blocking film 6 is provided in the channel; the inner distance between the port A2 and the port B3 is 8 cm (specific implementation , the inner spacing can be controlled within the range of 6-8cm).

[0029] In this embodiment, the infusion bag 1 is pre-filled with 1000 m of normal saline with a mass fraction of 0.9%, and the heparin capsule 4 contains 10 mg of heparin sodiu...

Embodiment 2

[0031] Example 2 Application of ECMO dedicated pipeline pre-filling circulation device

[0032] The conventional extracorporeal membrane oxygenation evacuation closed circuit is formed by connecting the centrifugal pump 7, the extracorporeal membrane lung 8 and the joint 9 in series through the pipeline 10, the pipeline 10 has a terminal a and a terminal b, and the pipeline 10 There are two tees on the top, which are respectively connected to the port A2 and port B3 of the ECMO special pipeline pre-fill circulation device through the exhaust pipe A11 and the pre-charge exhaust pipe B12.

[0033] The prefilling steps of the ECMO dedicated pipeline prefilling circulation device are as follows:

[0034] 1. Acupressure heparin capsule 4, the heparin sodium in the capsule breaks through the blocking film 6 under the action of pressure and enters the physiological saline in the infusion bag 1 to form a prefill;

[0035] 2. Connect end a and end b of the pipeline 10 through joint 9 ...

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...
