Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a fixation device. Background Technology

[0002] Extracorporeal membrane oxygenation (ECMO) is primarily used to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure, thus sustaining their lives. The core components of ECMO are the oxygenator (artificial lung, membrane lung) and the centrifugal pump (artificial heart, blood pump). Its working principle involves using the centrifugal pump to draw blood from the body, which is then propelled to the oxygenator. The oxygenator exchanges oxygen and removes carbon dioxide, before returning the oxygenated blood to the body. ECMO needs to adapt to different usage scenarios. In some scenarios, core components such as the oxygenator are not specifically mounted in a cart or a fixed portable frame, but rather require a flexible, stable, and reliable oxygenator mounting device that can be quickly disassembled and installed in different operating environments and is easily adjustable in angle. The flexible fixation device for the oxygenator has brought about some new problems, such as the need to pay special attention to the problem of medical devices falling off. When the oxygenator is placed at an angle or flipped, it cannot be fixed in all directions. The installation and replacement of the oxygenator cannot be quickly disassembled and cannot be adapted to the adjustment of the device's position. Summary of the Invention

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0026] like Figures 1 to 5 As shown, this application provides a fixing device for fixing a device 1 to be fixed. The device includes a fixing post 9, a snap-fit ​​member 2, and a support member.

[0027] The fixing post 9 and the snap-fit ​​2 are spaced apart on the support member, which is in the shape of a long arm rod.

[0028] The bottom of the device to be fixed 1 is provided with a central hole 18, the depth of which is greater than the diameter of the central hole 18; a first snap-fit ​​part 19 and a second snap-fit ​​part 20 are provided along the circumference of the device to be fixed 1; the fixing post 9 is disposed in the central hole 18; a boss 10 is provided on the side of the snap-fit ​​part 2 near the fixing post 9; the first snap-fit ​​part 19 is snap-fitted with the boss 10; a buckle 3 is movably disposed on the snap-fit ​​part 2 and is fastened to the second snap-fit ​​part 20.

[0029] It should be noted that the depth of the central hole 18 of the device to be fixed is greater than the diameter of the central hole 18 and less than the height of the device to be fixed, and the height of the fixing post 9 is equal to the depth of the central hole 18.

[0030] In the embodiments of this application, the first snap-fit ​​portion 19 and the second snap-fit ​​portion 20 are actually protruding structures provided on the outer shell of the device 1 to be fixed. The first snap-fit ​​portion 19 and the second snap-fit ​​portion 20 can be outer edge structures or other shapes, as long as they can cooperate with the buckle 3 and the boss 10 to fix the device to be fixed, they are all within the protection scope of this application.

[0031] In this embodiment, the device to be fixed 1 is an oxygenator in an extracorporeal membrane oxygenation (ECMO) system. Specifically, the device to be fixed 1 has a first locking part 19 and a second locking part 20 arranged along the circumferential direction, wherein the second outer edge 20 is located above the first locking part 19. A central hole 18 is provided at the bottom of the device to be fixed 1. The oxygenator is inserted into the central hole 18 to prevent the device to be fixed 1 from moving forward, backward, left, or right. The second locking part 20 is secured by a buckle 3 to prevent the device to be fixed 1 from moving upward. The device to be fixed 1 is fixed in this way, and it can be disassembled by pressing the buckle 3. The fixing device provided in this application can be quickly disassembled and installed in different environments, and the safety of preventing tipping and falling off is greatly increased. In addition, the engagement between the boss 10 and the first snap-fit ​​part 19 prevents the device to be fixed from tilting further, thereby achieving the function of fixing the device to be fixed. When the device to be fixed tilts, the original force is borne by the center hole 18 of the device to be fixed. Now, the second snap-fit ​​part 20 can also share some of the force, making the force on the device to be fixed more even and reducing the risk of damage to the device to be fixed. Especially in the environment of bumpy transportation, it is necessary to consider protecting the device to be fixed.

[0032] It should be noted that if the device to be fixed 1 is an oxygenator, the upper and lower covers of the oxygenator need to be connected to the intermediate shell of the oxygenator to form the entire shell of the oxygenator. The lower edge of the lower cover away from the intermediate shell is set on the boss 10, and the upper edge of the lower cover near the intermediate shell is connected to the buckle 3. In the embodiment of this application, the first snap-fit ​​part 19 is the lower edge of the lower cover, and the second snap-fit ​​part 20 is the upper edge of the lower cover.

[0033] like Figure 5 As shown, a protective shell 21 is vertically installed at the bottom of the entire oxygenator, and a gas outlet is provided at the bottom of the oxygenator. The protective shell 21 can keep the gas outlet at a certain distance from the plane, and the protective shell 21 can prevent the gas outlet from being blocked when the oxygenator is laid flat.

[0034] As a preferred embodiment of this application, such as Figure 2 As shown, the snap-fit ​​component 2 is provided with a fixed shaft 12, and the buckle 3 is rotatably mounted on the fixed shaft 12.

[0035] It should be noted that the fixing shaft 12 passes through the snap-fit ​​2 and is located in the middle of the snap-fit ​​2. The device to be fixed 1 can be installed into or removed from the fixing device simply by rotating the buckle 3.

[0036] As a preferred embodiment of this application, such as Figure 3 As shown, an elastic element 15 is provided on the fixed shaft 12, and the elastic element 15 is connected to the buckle 3.

[0037] It should be noted that in this embodiment, the elastic element 15 is a spring, and the elastic element 15 can enable the buckle 3 to automatically engage under the action of elastic force after the device to be fixed 1 is installed into the fixing device.

[0038] As a preferred embodiment of this application, such as Figure 5 As shown, the buckle 3 is provided with a hook, which is fastened to the second snap-fit ​​part 20. The hook is used to prevent the device to be fixed 1 from moving in the vertical direction.

[0039] It should be noted that, in order to facilitate the fastener 3 to cooperate with the first snap-fit ​​part 19 to fix the device 1 to be fixed, so as to prevent the device 1 to be fixed from moving in the vertical direction.

[0040] As a preferred embodiment of this application, such as Figure 2 and Figure 3 As shown, the fixing column 9 is provided with an anti-rotation component 8 to prevent the device 1 to be fixed from rotating.

[0041] It should be noted that an anti-rotation component 8 is added to the fixing column 9 to prevent the device to be fixed 1 from rotating, thereby achieving a better device to be fixed 1.

[0042] Specifically, when the anti-rotation component 8 is a first gear structure, a second gear structure that meshes with the first gear structure is provided on the side wall of the central hole 18.

[0043] As a preferred embodiment of this application, Figure 3 and Figure 5 As shown, a buffer 14 is provided around the fixed post 9, and the buffer 14 is used to fill the gap between the central hole 18 and the fixed post 9.

[0044] It should be noted that the buffer 14 can be made of elastic materials such as silicone, thermo-shrinkable elastomer (TPE), thermo-shrinkable rubber (TPR), polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), etc., preferably silicone. The buffer 14 is used to fill the gap between the center hole 18 of the device to be fixed 1 and the fixing post 9, and can buffer and protect the center hole 18 of the device to be fixed 1 when it is subjected to impact.

[0047] It should be noted that, as Figure 1 As shown, the fixing post 9 and the snap-fit ​​2 are vertically arranged on the first support member 11 in the same direction, and the first support member 11 and the second support member 13 are connected by a protrusion 17 in the groove 16, which can better fix the first support member 11 and the second support member 13 together. The second support member 13 and the adapter 5 are connected by a knob 4.

[0048] As a preferred embodiment of this application, such as Figures 1 to 3As shown, the length of the second support member 13 is greater than that of the first support member 11. A transition member 5 is provided at one end of the second support member 13 away from the fixed column 9. A clamping mechanism 6 is provided at one end of the transition member 5 away from the second support member 13. A locking mechanism is provided on the clamping mechanism 6. The clamping mechanism 6 is locked by the locking mechanism so as to fix the fixing device on the structural member 7.

[0049] It should be noted that by setting the second support member 13, it can be easily connected to the adapter member 5. The adapter member 5 is connected to the clamping mechanism 6, and the entire fixing device can be locked on the structural member 7 by the locking mechanism on the clamping mechanism 6.
