Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a quick-insert frame and an ECMO device with the quick-insert frame. Background Art

[0002] Extracorporeal Membrane Oxygenation (ECMO) is an extracorporeal circulation emergency device. The main function of this device is to draw venous blood out of the body, oxygenate it through an artificial heart-lung bypass made of special materials, and then inject it into the patient's arterial or venous system, thereby playing a partial heart-lung replacement role and maintaining oxygenated blood supply to human organs and tissues.

[0003] Extracorporeal membrane oxygenation (ECMO) equipment mainly consists of four important devices: ECMO host, centrifugal pump (also known as: blood pump), membrane lung (also known as: membrane oxygenator) and fixed bracket, which are the basic requirements for the operation of ECMO device. When patients wearing ECMO devices need to be transferred, fixed brackets are required to keep the centrifugal pump, membrane lung and ECMO host in a relatively constant position and angle to ensure the normal operation of the ECMO device.

[0004] However, in the actual emergency transport or ICU treatment using ECMO device, we found that the fixing bracket used to fix the centrifugal pump, membrane lung and ECMO host is not very convenient to use, such as Figure 1 As shown, component number 10 is an existing fixed bracket, component number 4 is an ECMO host, component number 7 is a membrane oxygenator, and component number 8 is a blood pump, which mainly has the following defects:

[0005] First, the existing fixed bracket is connected to the lower side of the ECMO host. In vertical projection, the fixed bracket and its connected centrifugal pump and membrane lung are completely exposed from the ECMO host, which increases the physical distance between the patient and the ECMO device, and increases the extension length of the venous and arterial tubes on the ECMO device. There are problems of mutual pulling between the tubes and the dragging of the tubes on the ground, which in turn causes the risk of the tubes falling off, thereby endangering the patient's life. It not only brings inconvenience to the operation and use, but also occupies the patient's activity space. When emergency transfer or ICU treatment is performed, the bed space is limited, the patient's limbs cannot be stretched and placed, and the limbs are squeezed with the ECMO device components for a long time, which is easy to cause pressure sores and the like;

[0006] Second, the existing fixed bracket is an integral fixed plug-in structure, which is directly plugged into the ECMO host and does not have the functions of folding and storage and flexible adjustment of angle and orientation. When the ECMO device needs to be intermittently suspended during treatment, the fixed bracket has a certain height and is mounted with a centrifugal pump and membrane lung, which again occupies the patient's treatment space. In addition, the fixed bracket cannot be flexibly adjusted in terms of angle and orientation, which endangers the normal operation of the ECMO device.

[0007] Therefore, there is an urgent need to design a quick-insert frame and an ECMO device with the quick-insert frame that can solve the above problems. Utility Model Content

[0008] In view of the problems existing in the prior art, the utility model provides a quick-insert frame and an ECMO device with the quick-insert frame. After adopting the quick-insert frame and the ECMO device, the space between the patient and the ECMO host is freed up through the setting of the structure and spatial orientation, which is convenient for shortening the physical distance between the patient and the ECMO host, avoiding the problem of mutual pulling between the pipes and the pipes dragging on the ground caused by the extension of the length of the venous tube and the arterial tube on the ECMO device, and facilitating the medical staff to operate the ECMO device, saving the patient's activity space, and allowing the patient's limbs to be stretched and placed in space, thereby avoiding the occurrence of limb pressure sores;

[0009] Not only can the quick-connect body and the quick-connect handle be flexibly separated, that is, the quick-connect frame can be separated from the quick-connect handle of the ECMO host as a whole, but the quick-connect body can also realize a rotational locking movement through a rotating mechanism, thereby achieving a folding and storage function, saving treatment space for patients, and at the same time flexibly adjusting the angle and orientation of the support frame.

[0015] One end of the support frame is connected to a membrane oxygenator, and the other end of the support frame is connected to a blood pump, and the membrane oxygenator and the blood pump are both located above the ECMO host;

[0016] In vertical projection, along the width direction of the ECMO host, the membrane oxygenator and the blood pump do not protrude from the side of the ECMO host;
