[0032] The following combination Figures 1 to 5 Embodiments of the present invention are described in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0033] In the description of the present invention, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] The present invention relates to a swing mechanism, which includes a support device, a support spindle 3101, and a drive assembly. The oxygenator is disposed in the support device, and the support device clamps and fixes the oxygenator. The top end of the support spindle 3101 is connected to the support device, and the drive assembly is connected to the support spindle 3101. The drive assembly drives the support spindle 3101 to perform a pendulum motion. The support spindle 3101 drives the support device and the oxygenator to rotate back and forth within a set angle range, realizing the pendulum motion of the support device and the oxygenator, so that the oxygenator swings to eliminate bubbles and prevent coagulation. When the ECMO system stops pumping, the swinging action of the support device helps to avoid platelet activation and prolong the blood anticoagulation time.

[0036] Specifically, the drive assembly includes a first spindle 3103 and a connecting base 3102. The connecting base 3102 is disposed at the first end of the first spindle 3103. The support spindle 3101 is connected to the connecting base 3102. The connecting base 3102 is provided with a bearing for mounting the support spindle 3101. The first spindle 3103 can rotate about its longitudinal axis, thereby driving the support spindle 3101 to swing. It will be understood that the drive assembly includes a driver, which includes a motor. The driver drives the first spindle 3103 to rotate. Specifically, the second end of the first spindle 3103 is connected to the driver.

[0037] With reference to the accompanying drawings, the swing mechanism includes a base 3400, a driver connected to the base 3400, and a first main shaft 3103 rotatably disposed on the base 3400. Specifically, the swing mechanism includes a bearing seat 3104, the bearing seat 3104 is connected to the base 3400, and the first main shaft 3103 is disposed on the bearing seat 3104.

[0038] In some examples, the driving assembly is provided with a speed regulating button to adjust the motor power, thereby adjusting the rotation speed of the first spindle 3103 and adjusting the swing frequency of the support spindle 3101 .

[0039] In some examples, the drive assembly includes a second transmission assembly, through which the driver is connected to the first main shaft 3103 and drives the first main shaft 3103 to rotate. Specifically, the second transmission assembly includes a connecting rod mechanism, which includes a rocker arm, a third connecting rod, and a fourth connecting rod. One end of the third connecting rod is hinged to the rocker arm, which is connected to the rotating shaft of the driver. The other end of the third connecting rod is hinged to the fourth connecting rod, which is connected to the first main shaft 3103, thereby enabling the driver to drive the first main shaft 3103 to rotate.

[0040] Of course, as an alternative, it can also be designed as follows: in some examples, the second transmission assembly realizes transmission between the driver and the first main shaft 3103 by means of gear meshing. In some examples, the second transmission assembly realizes transmission between the driver and the first main shaft 3103 by means of belt drive. In some examples, the first main shaft 3103 is connected to the rotating shaft of the driver.

[0041] It is understood that, driven by the support main shaft 3101, the support device and the oxygenator perform a pendulum motion, which effectively achieves defoaming and anti-coagulation. Furthermore, considering that the outer wall of the oxygenator is connected to a pipeline, when the oxygenator swings with the support device, the pipeline connected to the oxygenator will be pulled. Therefore, under the drive of the drive assembly, the support main shaft 3101 is designed to be able to pendulum motion and simultaneously rotate about its own longitudinal axis. Driven by the support main shaft 3101, the support device rotates synchronously about the longitudinal axis of the support main shaft 3101, thereby achieving the simultaneous pendulum motion and self-rotation of the support device and the oxygenator. It should be noted that the pendulum motion and self-rotation of the oxygenator are both the integrated motions of the two when the support device is clamped and fixed to the oxygenator, and the self-rotation of the oxygenator is a reciprocating rotation within a set angle range.

[0042] During the oxygenator's pendulum motion, the oxygenator rotates and twists, ensuring that the position of the tubing connection on the outer wall of the oxygenator remains constant or changes minimally. This prevents the oxygenator from swinging and pulling on the tubing, preventing a "whiplash" motion in the blood tubing and ensuring smooth blood flow. Furthermore, the oxygenator's rotation allows the operator to observe from the side and front of the oxygenator to check for thrombosis on the wall of the oxygenator that is blocked by the support device.

[0043] As an embodiment, the bracket main shaft 3101 is rotatably arranged on the connecting seat 3102, and the driving component includes a first transmission component. When the driving component drives the bracket main shaft 3101 to pendulum motion, the bracket main shaft 3101 realizes its own rotation through the first transmission component.

[0044] Furthermore, the first transmission assembly includes a first tooth structure and a second gear. The first tooth structure is fixedly arranged. Specifically, the first tooth structure is arranged on the base 3400, and the first tooth structure is provided with a plurality of gear teeth around at least part of the circumference of the first main shaft 3103. The second gear is arranged on the bracket main shaft 3101, and the second gear is engaged with the first tooth structure.

[0045] It is understandable that when the stent main shaft 3101 performs a pendulum motion, the second gear rolls on the first tooth structure, and the second gear drives the stent main shaft 3101 to rotate, so that the stent main shaft 3101 rotates around its own axis, thereby realizing the self-rotation of the stent device and the oxygenator.

[0046] In some examples, the teeth of the first toothed structure and the second gear are both configured as bevel teeth. Furthermore, the first toothed structure and the second gear are each configured as a bevel gear, and the first toothed structure is coaxially disposed on the base 3400 with the first main shaft 3103. Referring to the accompanying drawings, the first toothed structure is configured as a first bevel gear 3201, and the second gear is configured as a second bevel gear 3202.

[0047] With reference to the accompanying drawings, the first bevel gear 3201 is fixedly connected to the bearing seat 3104, the base 3400 is provided with a vertical plate, the driver and the second transmission assembly are arranged in the rear area of ​​the vertical plate, the support spindle 3101 and the first transmission assembly are arranged in the front side of the vertical plate, the first spindle 3103 passes through the vertical plate, and the bearing seat 3104 is fixedly connected to the vertical plate. In some examples, as an alternative solution, it is also possible to design: the first bevel gear 3201 is arranged on the base 3400 and fixed, specifically, the first bevel gear 3201 is fixed to the vertical plate.

[0048] Regarding the structures of the first tooth structure and the second gear, an alternative design is also possible: in some examples, the first tooth structure is configured as an arc structure, and the gear teeth of the first tooth structure are bevel teeth or straight teeth.

[0049] In some examples, the rocking mechanism includes a counterweight component 3300 , which is configured as a counterweight ball. The counterweight component 3300 is connected to the bottom end of the bracket main shaft 3101 to increase the stability of the rocking of the bracket device.

[0050] In one embodiment, the stent device includes a clamping assembly connected to the stent main shaft 3101 and used to clamp the oxygenator. Specifically, the clamping assembly includes a support and two clamping arms 1200. The support is connected to the top of the stent main shaft 3101. The two clamping arms 1200 are both mounted on the support. The oxygenator is placed on the support. The two clamping arms 1200 respectively clamp two sides of the oxygenator. The support and the two clamping arms 1200 form a three-point clamping structure for the oxygenator, achieving a stable clamping of the oxygenator.

[0051] Furthermore, one end of the clamping arm 1200 is hinged to the support, so that the two clamping arms 1200 can be opened and closed, making it convenient for the clamping assembly to clamp the oxygenator.

[0052] With reference to the accompanying drawings, the clamping assembly includes a clamping arm linkage structure 1100, which is located between two clamping arms 1200 and hingedly connected to the sidewalls of the two clamping arms 1200. It is understood that the clamping arm linkage structure 1100 can drive the two clamping arms 1200 to move synchronously to achieve opening and closing. With reference to the accompanying drawings, the clamping arm linkage structure 1100 moves in a first direction to drive the two clamping arms 1200 to open, releasing the oxygenator. Correspondingly, the clamping arm linkage structure 1100 moves in a direction opposite to the first direction to drive the two clamping arms 1200 to clamp the oxygenator.

[0053] In some examples, the clamping arm 1200 is connected to the clamping arm linkage structure 1100 via a first connecting rod 1101 , and both ends of the first connecting rod 1101 are hinged to the clamping arm 1200 and the clamping arm linkage structure 1100 , respectively.

[0054] As an embodiment, the support device includes a handle assembly, which is connected to a clamping assembly. The clamping arm linkage structure 1100 is hinged to the handle assembly. It is understandable that the operator can drive the clamping arm linkage structure 1100 by operating the handle assembly, thereby driving the clamping assembly to clamp or release the oxygenator.

[0055] Specifically, the handle assembly includes a handle structure 2200. The first end of the handle structure 2200 is hingedly connected to the support, and the clamp arm linkage structure 1100 is hingedly connected to the handle structure 2200. By moving the second end of the handle structure 2200, the handle structure 2200 can be rotated, thereby driving the clamp arm linkage structure 1100 to move, and in turn, driving the clamp arms 1200 to open and close. Specifically, moving the second end of the handle structure 2200 can drive the clamp arm linkage structure 1100 in a first direction, thereby opening the two clamp arms 1200. Correspondingly, rotating the handle structure 2200 to drive the clamp arm linkage structure 1100 in a direction opposite to the first direction can clamp the two clamp arms 1200 to secure the oxygenator.

[0056] Furthermore, the handle assembly includes a second connecting rod 2100. The handle structure 2200 is hingedly connected to the support via the second connecting rod 2100. Specifically, the two ends of the second connecting rod 2100 are hingedly connected to the first end of the handle structure 2200 and the support, respectively. Referring to the accompanying drawings, by moving the second end of the handle structure 2200, the second connecting rod 2100 can be driven to rotate in the second direction, thereby driving the clamping arm linkage structure 1100 to move in the first direction, thereby releasing the clamping assembly from clamping the oxygenator.

[0057] Specifically, the first end of the second connecting rod 2100 is hinged to the handle structure 2200, and the second end is hinged to the support. Referring to the accompanying drawings, when operating the handle structure 2200 to release the clamp, the second end of the handle structure 2200 is moved, which drives the second connecting rod to rotate in the second direction, thereby driving the clamping arm linkage structure 1100 to move in the first direction and capable of causing the clamping arm 1200 to open. Accordingly, to clamp the oxygenator, the handle structure 2200 drives the second connecting rod to rotate in the direction opposite to the second direction, thereby pushing the clamping arm linkage structure to move in the direction opposite to the first direction and driving the clamping arm 1200 to clamp the oxygenator.

[0058] Regarding the hinge connection between the clamp arm linkage structure 1100 and the handle assembly, as an alternative, it can also be designed as follows: the clamp arm linkage structure 1100 is hinged to the second connecting rod 2100, and the clamp arm linkage structure 1100 is arranged close to the first end of the second connecting rod 2100.

[0059] It can be understood that the support is provided with a hinge area 1300 for installing the second connecting rod 2100. Furthermore, the hinge area 1300 is provided with a first limiting structure 1301. The first limiting structure 1301 is used to support the side wall of the second connecting rod 2100 to prevent the second connecting rod 2100 from rotating and causing the clamping to be released during improper operation. The first limiting structure 1301 is used to prevent the clamping component from loosening.

[0060] Specifically, when the clamping assembly is subjected to external force due to improper operation, the clamping arm linkage structure 1100 has a tendency to move in the first direction due to the external force, or the clamping arm 1200 is opened by the external force, causing the clamping arm linkage structure 1100 to have a tendency to move in the first direction, so that the clamping arm linkage structure 1100 applies a force to the handle assembly and causes the second connecting rod 2100 to have a tendency to rotate in the opposite direction to the second direction. The first limiting structure 1301 presses against the side wall of the second connecting rod 2100 to prevent the second connecting rod 2100 from rotating.

[0061] In some examples, the first limiting structure 1301 has a limiting fulcrum for abutting against the side wall of the second connecting rod 2100, and the position abutted by the limiting fulcrum is at the side wall in the middle of the second connecting rod 2100 or near the side wall in the middle of the second connecting rod 2100. In some examples, the first limiting structure 1301 has a limiting side wall for abutting against the side wall of the second connecting rod 2100, and the limiting side wall is in contact with the side wall of the second connecting rod 2100.

[0062] It should be noted that if the clamping arm linkage structure 1100 applies a force to the handle assembly, causing the second connecting rod 2100 to have a tendency to rotate along the second direction, since the end of the handle structure 2200 is fixedly connected to the support, it can effectively prevent the second connecting rod 2100 from rotating, thereby playing an anti-loosening role.

[0063] In one embodiment, the hinge region 1300 is recessed in the support, and the end of the second connecting rod 2100 extends into the hinge region 1300 and is hingedly connected to the sidewalls of the hinge region 1300. Specifically, the hinge axis at the second end of the second connecting rod 2100 is respectively connected to the two opposite sidewalls of the hinge region 1300. It will be understood that in the hinge region 1300, the sidewall between the two opposite sidewalls where the hinge axis is located serves as the first limiting structure 1301.

[0064] Regarding the hinge area 1300, as an alternative, it can also be designed as follows: a partial area of ​​the support surface serves as the hinge area 1300 or a hinge seat is provided on the surface of the support, and the first limiting structure 1301 is protruded and provided on the support surface.

[0065] In one embodiment, the second end of the handle structure 2200 is detachably connected to the support to prevent the handle structure 2200 from loosening. It will be appreciated that after the handle structure 2200 is rotated, the clamping arm 1200 clamps the oxygenator while the handle structure 2200 and the support are fixedly connected. To release the clamping, the fixed connection between the handle structure 2200 and the support is separated to allow the handle structure 2200 to be rotated.

[0066] Specifically, the second end of the handle structure 2200 is provided with an adsorption structure 2201, which is fixedly connected to the support in a magnetic manner and can be easily disassembled and separated. In some examples, the support is provided with a magnetic member or electromagnetic structure to magnetically fix the adsorption structure 2201.

[0067] Of course, as an alternative, it can also be designed as follows: In some examples, the adsorption structure 2201 is provided with a magnetic member or an electromagnetic structure. In some examples, the adsorption structure 2201 is fixedly connected to the support in a negative pressure adsorption manner, specifically, the adsorption structure 2201 includes a negative pressure suction nozzle.

[0068] With reference to the accompanying drawings, one end of the handle structure 2200 is bent to form an L-shaped rod, and the second connecting structure 2300 is disposed on the end structure near the second connecting rod 2100. Alternatively, in some examples, both ends of the handle structure 2200 are bent toward the same side of the handle structure 2200. In some examples, the handle structure 2200 is configured as a straight rod or a curved rod.

[0069] Regarding the detachable connection between the second end of the handle structure 2200 and the support, as an alternative, another design is: the support is provided with a handle clamping area, and the handle clamping area is formed as a recess. Specifically, the handle clamping area is configured as a hole, and the second end of the handle structure 2200 is provided with a handle clamping portion. The handle clamping portion is inserted into the handle clamping area, and the outer wall of the handle clamping portion and the inner wall of the handle clamping area have an interference fit to achieve the connection between the handle structure 2200 and the support. Alternatively, the handle clamping area is configured as a protrusion, and the handle clamping portion has a recessed area.

[0070] In one embodiment, the position of the clamping arm linkage structure 1100 is adjustable, thereby adjusting the clamping force of the clamping arm 1200 on the oxygenator or adjusting the opening and closing range of the clamping arm 1200 according to the size of the oxygenator. It should be noted that in this case, the position of the clamping arm linkage structure 1100 is fine-tuned.

[0071] Specifically, when the clamping assembly is equipped with an oxygenator and the second end of the handle structure 2200 is connected to the support, if the clamping arm linkage structure 1100 is moved in a direction opposite to the first direction at the position of the clamping assembly and then fixed in position, the clamping force of the clamping arm 1200 can be increased. Correspondingly, if the clamping arm linkage structure 1100 is moved in the first direction and then fixed in position, the clamping force of the clamping arm 1200 is reduced.

[0072] Specifically, the bracket device includes a first connecting structure 1401, the two ends of which are respectively connected to the clamp arm linkage structure 1100 and the handle assembly. One end of the first connecting structure 1401 is hinged to the clamp arm linkage structure 1100, and the other end of the first connecting structure 1401 is connected to the handle assembly. The first connecting structure 1401 is connected to the handle structure 2200. Alternatively, an alternative design can be: one end of the first connecting structure 1401 is hinged to the handle assembly, and the other end of the first connecting structure 1401 is connected to the clamp arm linkage structure 1100.

[0073] Furthermore, the position of the first connecting structure 1401 is movable to adjust the position of the clamp arm linkage structure 1100 along a first direction. Specifically, when the first connecting structure 1401 moves relative to the handle assembly in the first direction, it can drive the clamp arm linkage structure 1100 to move in the first direction, reducing the clamping force of the clamping arm 1200. When the first connecting structure 1401 moves relative to the handle assembly in a direction opposite to the first direction, it can drive the clamp arm linkage structure 1100 to move in a direction opposite to the first direction, increasing the clamping force.

[0074] As an embodiment, the handle assembly includes a second connecting structure 2300, which is connected to the handle structure 2200. Furthermore, the handle assembly is connected to the first connecting structure 1401 via the second connecting structure 2300. Alternatively, it can be designed as follows: the second connecting structure 2300 is connected to the second connecting rod 2100.

[0075] With reference to the accompanying drawings, the first connecting structure 1401 is provided with a first mounting hole, which is arranged along a first direction, and the second connecting structure 2300 extends into the first mounting hole. Furthermore, the handle assembly can be connected to the first connecting structure 1401 by fixedly connecting the second connecting structure 2300 to the inner side wall of the first mounting hole.

[0076] Furthermore, the second connecting structure 2300 can move along the length of the first mounting hole to adjust the position of the first connecting structure 1401 relative to the handle assembly. Specifically, the second connecting structure 2300 is driven to move within the first connecting structure 1401 in a screw transmission manner, thereby adjusting the position of the first connecting structure 1401 relative to the handle assembly.

[0077] In some examples, the bracket device includes a first movable structure 1402, which extends into the first mounting hole from the other end of the first mounting hole, and the first movable structure 1402 is provided with an external thread, and the first mounting hole is provided with an internal thread, so that the outer wall of the first movable structure 1402 is threadedly connected to the inner wall of the first mounting hole, and one end of the first movable structure 1402 abuts the handle assembly. Specifically, the end of the first movable structure 1402 can abut the second connecting structure 2300.

[0078] It is understood that if the first movable structure 1402 is rotated so as to gradually extend into the first mounting hole, the first movable structure 1402 can press against the second connecting structure 2300 and move in the first direction, thereby causing the clamping arm linkage structure 1100 to move in a direction opposite to the first direction relative to the handle assembly, thereby increasing the clamping force. If the first movable structure 1402 is rotated in the opposite direction, the abutment of the first movable structure 1402 against the second connecting structure 2300 can be released, allowing the second connecting structure 2300 to be further extended along the length of the first mounting hole, causing the clamping arm linkage structure 1100 to move in the first direction, thereby reducing the clamping force.

[0079] Furthermore, the bracket device includes a first locking structure 1403, which is connected to the first connecting structure 1401 and fixes the second connecting structure 2300 to the first connecting structure 1401. Specifically, the first locking structure 1403 is provided with an external thread, and the side wall of the first mounting hole is provided with a threaded hole extending therethrough. The first locking structure 1403 is threadedly connected to the side wall of the first mounting hole, and one end of the first locking structure 1403 abuts against the outer side wall of the second connecting structure 2300, thereby fixing the second connecting structure 2300 to the side wall of the first mounting hole.

[0080] Regarding the arrangement of the first movable structure 1402, as an alternative, it can also be designed that one end of the first movable structure 1402 is connected to the handle assembly. In some examples, the end of the first movable structure 1402 is rotatably connected to the end of the second connecting structure 2300. In this case, the first movable structure 1402 can both push and pull the second connecting structure 2300 in the first mounting hole, and the position is fixed by the threaded connection between the first movable structure 1402 and the first mounting hole, thereby fixing the position of the second connecting structure 2300 in the first mounting hole. In some examples, the first movable structure 1402 passes through the first mounting hole, and the end of the first movable structure 1402 is rotatably connected to the handle structure 2200 or the second connecting rod 2100.

[0081] Regarding the structure for adjusting the clamping force of the clamping arm linkage structure 1100, as an alternative solution, the position of the clamping arm linkage structure 1100 relative to the first connecting structure 1401 can be adjusted along a first direction and a direction opposite to the first direction. Specifically, the first movable structure 1402 can drive the clamping arm linkage structure 1100 to move relative to the first connecting structure 1401, thereby achieving movement of the clamping arm linkage structure 1100 relative to the handle assembly. It is understood that in this case, the second connecting structure 2300 is designed to be connected to the clamping arm linkage structure 1100.

[0082] In one embodiment, the clamping arm 1200 is provided with a clamping sleeve 1201, which is used to contact the oxygenator. Furthermore, the clamping sleeve 1201 is made of an elastic material, specifically, sponge, silicone, or rubber.

[0083] As an embodiment, the support includes a support base 1501 and a clamp arm base 1502. The oxygenator is placed on the support base 1501, and the support base 1501 is arranged at the top of the support main shaft 3101. With reference to the accompanying drawings, the clamp arm base 1502 is connected to the support base 1501, the clamp arm 1200 is hinged to the clamp arm base 1502, the second connecting rod 2100 is hinged to the clamp arm base 1502, and the second end of the handle structure 2200 is detachably connected to the support base 1501.

[0084] Of course, alternative designs are also possible: in some examples, the second connecting rod 2100 is hinged to the bracket seat 1501. In some examples, the second end of the handle structure 2200 is detachably connected to the clamping seat.

[0085] As an embodiment, the support base 1501 is provided with a third connecting structure 1503, which is used to connect to the bottom of the oxygenator. In conjunction with the accompanying drawings, the third connecting structure 1503 is provided on the surface of the support base 1501 to position and connect the oxygenator.

[0086] Furthermore, the third connecting structure 1503 is coaxially arranged with the main axis 3101 of the stent, and the center of the bottom of the oxygenator is connected to the third connecting structure 1503. It is understandable that in this case, the oxygenator is coaxially arranged with the main axis 3101 of the stent.

[0087] As a supplementary explanation on the clamp arm seat 1502 and the bracket seat 1501 , an alternative design is available: the clamp arm seat 1502 and the bracket seat 1501 are integrally formed. In this case, the third connecting structure 1503 is provided on the bracket seat 1501 .

[0088] In some examples, a second limiting structure 1504 is provided on the outer side wall of the third connecting structure 1503. At least one second limiting structure 1504 is provided. With reference to the accompanying drawings, two second limiting structures 1504 are provided. The second limiting structure 1504 is configured as a clamping plate. The second limiting structure 1504 is used to connect to the bottom of the oxygenator. The second limiting structure 1504 can prevent the oxygenator from rotating in the support device.

[0089] Regarding the third connecting structure 1503 and the second limiting structure 1504, as an alternative, the third connecting structure 1503 can be configured as a polygonal connecting column in some examples. In some examples, multiple third connecting structures 1503 are provided, and each third connecting structure 1503 is spaced apart along the circumference of the support base 1501 around the rotation axis of the support main shaft 3101.

[0090] The present invention relates to an oxygenator, which is clamped by a bracket device. A recessed first clamping area is provided at the bottom of the oxygenator, and a third connecting structure 1503 extends into the first clamping area.

[0091] Furthermore, in a case where the second limiting structure 1504 provided for the third connection structure 1503 is a card plate, the first clamping area has a card slot matching the second limiting structure 1504 .
