Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an ECMO pump head adapter conversion device. Background Technology

[0002] ECMO (Extracorporeal Membrane Oxygenation) is an extracorporeal circulation support device that provides cardiopulmonary support to critically ill patients with cardiopulmonary failure, reducing the burden on their hearts and lungs and thus buying more time for rescue. It is suitable for various cardiac and pulmonary diseases, such as cardiogenic shock, acute myocarditis, severe pneumonia, and acute respiratory distress syndrome. An ECMO system mainly consists of a main unit, pump head, membrane oxygenator, heater, and arterial and venous catheters. The pump head and membrane oxygenator are the main consumables in the ECMO system, with the pump head directly connected to the main unit.

[0003] Currently, the main suppliers of ECMO machines, both domestically and internationally, are European and American manufacturers. The lack of a unified interface standard for ECMO equipment and pump heads from different manufacturers leads to incompatibility between different devices and pump heads. When supply disruptions occur with consumables, it becomes impossible to replace them with other pump heads or consumables. Furthermore, due to the high price of ECMO equipment, the cost of purchasing new equipment to replace pump heads is also very high.

[0004] The aforementioned issues severely limit the use of ECMO. In the face of emergencies such as pandemics, manufacturers with a high market share of ECMO equipment are prone to supply shortages of consumables, while manufacturers with a lower market share may find their consumables unavailable, leading to delays in patient treatment. To improve ECMO compatibility and reduce the difficulty of promoting ECMO, an ECMO pump head adapter conversion device is adopted, enabling compatibility between ECMO equipment and consumables from different manufacturers.

[0033] The following is in conjunction with the appendix Figure 1-6 The present invention will be further illustrated by the embodiments.

[0034] The ECMO pump head adapter conversion device consists of a pump head adapter module 1 and an equipment adapter module 2. The equipment adapter module is compatible with different ECMO devices, and the adapter modules for different ECMO devices have different interface types and internal magnetic drive disk magnet arrangements. The pump head adapter module and the equipment adapter module work together to drive the pump head. The pump head adapter modules are available in both forward and reverse rotation versions to facilitate connection to devices and consumables with different rotation directions.

[0035] The device adapter module consists of a device adapter module housing 201, a device adapter module drive disk 202, and a device mating magnet 203.

[0036] The device adapter module housing 201 includes a rotary locking and positioning device that mates with the pump head adapter module housing 101, and its lower shape is the size and fixing structure of a pump head that mates with an ECMO device.

[0037] The device adapter module drive disk 202 connects the device mating magnet 203 and the pump head adapter module 1, and transmits the rotation and torque of the device mating magnet 203 to the pump head adapter module 1 through bevel gears.

[0038] The device can be equipped with a multi-pole magnetic ring or a multi-group magnetic arrangement, which can rotate with the ECMO device through magnetic coupling. Different ECMO devices have different types of magnets and magnetic pole distributions.

[0039] When the pump head and the equipment rotate in the same direction, the pump head adapter module 1 and the transmission principle are as follows: Figure 3 , Figure 4 .

[0040] When the pump head and the equipment rotate in the same direction, the pump head adapter module 1 consists of a pump head adapter module housing 101, a pump head mating magnet 102, a co-rotating transmission gear 103, and a pump head adapter module drive disk 104.

[0041] The pump head adapter module housing 101 includes a rotary locking and positioning device that cooperates with the equipment adapter module housing 201, and the upper structure is a fixed structure for the adapter pump head.

[0042] The pump head and the magnet 102 can be a multi-pole magnetic ring or a multi-group magnet arrangement, which can rotate with the ECMO pump head in a magnetic coupling manner. Different pump heads have different types of magnets and magnetic pole distributions.

[0043] The co-rotating transmission gear 103 connects the device adapter module drive disk 202 and the pump head adapter module drive disk 104, enabling the device adapter module drive disk 202 and the pump head adapter module drive disk 104 to rotate in the same direction.

[0044] The pump head adapter module drive disk 104 connects the pump head to the magnet 102 and the co-rotating transmission gear 103, transmitting rotation and torque.

[0045] When the pump head rotates in the opposite direction to the equipment, the pump head adapter module 1 consists of a pump head adapter module housing 101, a pump head mating magnet 102, a reverse rotation transmission gear 113, and a pump head adapter module drive disk 104.

[0046] The reverse rotation transmission gear 113 can cause the device-cooperating magnet 203 and the pump head-cooperating magnet 102 to rotate in opposite directions, thereby causing the ECMO device and the pump head to rotate in opposite directions.

[0047] When using it, first select the device adapter module 2 that can be fixed with the ECMO device, and then select the pump head adapter module 1 according to the structure and rotation direction of the selected pump head to achieve mutual adaptation between ECMO devices and pump heads with various rotation directions, sizes and magnet arrangement methods.
