[0043] See also Figures 1 to 3 The present application provides a host device A. The host device A can realize quick plug-in and pull-out transfer between two components through a bracket structure 10. Figure 1 is a cross-sectional view of a support structure 10 according to an embodiment of the present application. Figure 2 for Figure 1 The stent structure 10 shown is applied to a stereoscopic view of an extracorporeal circulatory assist system B. Figure 3for Figure 1 The support structure 10 is shown as a stereogram of a host device A. In the present application, the support structure 10 is used to quickly connect the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40. Of course, in other embodiments of the present application, the support structure 10 can also realize the rapid fixation and transfer of other components. The principle of its rapid installation and transfer is substantially the same as the principle of the above-mentioned rapid connection of the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40, which will not be repeated here.

[0044] When the host device A of the present application uses the support structure 10 to connect the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40, the support structure 10 can realize the rapid disassembly, assembly and transfer of the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40, which is convenient for use. The specific structure of an embodiment of the host device A is introduced below.

[0045] See also Figures 1 to 5 In one embodiment, the host device A includes a host 50, the host 50 has a handle 510, the handle 510 includes at least one interface 511 and a fixing component 530, the fixing component 530 is used to lock or unlock with one end of the support structure 500 via the interface 511, and the other end of the support structure 500 is used to connect with the functional components to realize the simultaneous carrying and transportation of the host device A and the functional components.

[0046] The functional components can be locked or unlocked to the fixed component 530 of the host 50 through the support structure 10. When the extracorporeal auxiliary circulation system B needs to be portable and miniaturized, such as in inter-hospital transport, outdoor first aid, emergency treatment and other scenarios, the functional components can be directly pluggably installed on the host 50 through the support structure 10. In this way, medical staff can directly carry the host 50 to achieve portable transportation of the entire system to meet usage requirements.

[0047] See also Figure 3 The host 50 has a handle 510, the handle 510 has at least an interface 511, the fixing component 530 is arranged in the interface 511 of the handle 510, and the connecting bracket 200 can be plugged into and installed in the fixing component 530 of the handle 510. In other words, the bracket structure 10 is connected to the handle 510 of the host 50, and the functional accessories are connected to the fixing component 530 of the handle 510 through the bracket structure 10.

[0048] It can be understood that the fixing assembly 530 is integrated into the interface 511 of the handle 510 to form a mounting position for installation on the handle 510, so that the bracket structure 10 can be directly plugged and installed into the mounting position through the interface 511 to achieve rapid installation and fixation of the bracket structure 10. Of course, in other embodiments of the present application, the bracket structure 10 can also be set at other positions of the host 50, as long as the functional accessories can be quickly installed and fixed.

[0049] See also Figure 1 and Figure 3 , the functional components include a blood pump 20, an oxygenator 30 and a portable oxygen cylinder 40, and there are two support structures 10, one of which connects the host 50 and the oxygenator 30 with the blood pump 20, and the other support structure 10 connects the host 50 with the portable oxygen cylinder 40. In other words, the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are directly plugged and installed to the host 50 through the support structure 10. In this way, medical staff can directly carry the host 50 to realize the portable transportation of the entire system to meet the use requirements.

[0050] Moreover, in the present application, the fixing component 530 is integrated into the host 50, and the blood pump 20 and the oxygenator 30 are connected through the connecting bracket 200 of one support structure 10, and the portable oxygen cylinder 40 is connected through the connecting bracket 200 of another support structure 10, so that the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 can be quickly plugged and installed to the host 50 through the cooperation of the connecting bracket 200 in the support structure 10 and the fixing component 530, which is convenient for portable transportation.

[0051] In order to better describe the process of achieving portable transportation of the host device A, the specific structure of the bracket structure 10 is first introduced here.

[0052] See also Figures 1 to 5 In one embodiment, the support structure 10 includes a connecting bracket 200 and a locking assembly 300. The fixing assembly 530 includes a fixing shell 531 and a positioning insert 532. The positioning insert 532 is disposed in the fixing shell 531 and is surrounded by the fixing shell 531 to form an installation position. One end of the connecting bracket 200 can be plugged and installed in the installation position. The locking assembly 300 can be movably disposed on the connecting bracket 200. The locking assembly 300 includes a locking member 330, a transmission member 320 and an unlocking member 310. The transmission member 320 is connected to the locking member 330 and the unlocking member 310 through the connecting bracket 200. The locking member 330 can be locked or unlocked on the positioning insert 532. Figure 4 for Figure 1 The support structure 10 shown is a three-dimensional view of connecting the blood pump 20 and the oxygenator 30. Figure 5 for Figure 1 The support structure 10 is shown in a perspective view connected to a portable oxygen cylinder 40 .

[0053] The fixing assembly 530 is a fixing interface that matches the support structure 10. The connecting bracket 200 is a housing of the locking assembly 300. At least a portion of the locking assembly 300 can move in the connecting bracket 200. One end of the connecting bracket 200 is pluggably connected to the fixing assembly 530. Moreover, the other end of the connecting bracket 200 is also used to connect a component to fix the component to the fixing assembly 530. For example, the connecting bracket 200 can connect the blood pump 20 and the oxygenator 30, and the connecting bracket 200 can connect the portable oxygen cylinder 40 (please refer to Figure 3 As shown). Of course, the connecting bracket 200 can also be connected to other components to be fixed. When locking, one end of the connecting bracket 200 is inserted into the fixing assembly 530, and the locking assembly 300 can be locked and connected with the fixing assembly 530 to fix one end of the connecting bracket 200 in the fixing assembly 530. When unlocking, the unlocking member 310 of the locking assembly 300 is pressed, and the locking assembly 300 unlocks the connecting bracket 200 and the fixing assembly 530, and one end of the connecting bracket 200 can be pulled out from the fixing assembly 530.

[0054] Specifically, the fixing assembly 530 includes a fixing housing 531 and a positioning insert 532. The positioning insert 532 is disposed in the fixing housing 531 and is surrounded by the fixing housing 531 to form an installation position (not marked), and the installation position is provided for plugging and unplugging the connecting bracket 200. The locking assembly 300 includes a locking member 330, a transmission member 320 and an unlocking member 310. The transmission member 320 transmits and connects the unlocking member 310 and the locking member 330. The transmission member 320 is disposed in the connecting bracket 200, the locking member 330 is disposed at one end of the connecting bracket 200, and the unlocking member 310 is disposed at the other end of the connecting bracket 200.

[0055] The locking member 330 can lock or unlock the positioning insert 532. When the unlocking member 310 is pressed, the unlocking member 310 can drive the transmission member 320 to drive the locking member 330 to move, so that the locking member 330 is unlocked from the positioning insert 532; when the locking member 330 abuts against the positioning insert 532 and is clamped on the positioning insert 532, the locking member 330 is locked to the positioning insert 532. Specifically, when one end of the connecting bracket 200 is inserted into the installation position, the locking member 330 is clamped on the positioning insert 532 to achieve the locking of the connecting bracket 200. At this time, the connecting bracket 200 cannot be pulled out from the installation position. When the unlocking member 310 is pressed, the unlocking member 310 can drive the locking member 330 to separate from the positioning insert 532 through the transmission member 320 to achieve the unlocking of the connecting bracket 200. At this time, the connecting bracket 200 can be pulled out from the installation position.

[0056] In the support structure 10 of the above embodiment, one end of the connecting bracket 200 can be plugged and installed in the fixing assembly 530, and locking and unlocking are achieved by the cooperation of the locking assembly 300 and the fixing assembly 530. When the support structure 10 connects the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40, the fixing assembly 530 is arranged on the mainframe 50 or the trolley 60, and the connecting bracket 200 of the support structure 10 connects the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40. In this way, the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40 can be quickly disassembled and transferred between the mainframe 50 and the trolley 60 through the cooperation of the connecting bracket 200 and the fixing assembly 530, which is convenient for use.

[0057] It can be understood that the fixing assembly 530 and the connecting bracket 200 are separately provided. The fixing assembly 530 is provided on a fixed body such as the host 50 or the trolley 60. The connecting bracket 200 connects the host 50 or the trolley 60 with the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40 (such as Figure 3 When in use, one end of the connecting bracket 200 is inserted into the corresponding fixing body fixing assembly 530 to realize the rapid installation of the functional component. When the functional component needs to be transferred, the fixing assembly 530 also needs to be set on the other fixing body. At this time, the functional component is pulled out from the fixing assembly 530 of the previous fixing body and then installed in the fixing assembly 530 of the other fixing body.

[0058] In one embodiment, when unlocking, the unlocking member 310 drives the locking member 330 to move out of the installation position through the transmission member 320, and when locking, the force of the transmission member 320 causes the locking member 330 to move into the installation position. That is, when unlocking is required, the unlocking member 310 is pressed, and the unlocking member 310 can drive the transmission member 320 to move, and then the transmission member 320 can drive the locking member 330 to move, so that the locking member 330 moves out of the installation position and breaks away from the abutment relationship with the positioning insert 532, so that the locking member 330 can be unlocked / pulled out from the fixing assembly 530.

[0059] See also Figure 1 In one embodiment, the connecting bracket 200 includes a main bracket 210 and a bracket seat 220. One end of the main bracket 210 can be plugged and installed in the installation position, and the bracket seat 220 is installed at the other end of the main bracket 210. The transmission member 320 can be movably set in the main bracket 210. The unlocking member 310 can be pressed and set on the bracket seat 220 and connected to the transmission member 320.

[0060] exist Figure 1In the direction shown, the main support 210 cooperates with the support seat 220 to form the connecting support 200, the left end of the main support 210 can be plugged and installed in the installation position of the fixing assembly 530, and the right end of the main support 210 is connected to the support seat 220. The main support 210 is hollow, and the transmission member 320 is movably installed in the main support 210. In this way, when the unlocking member 310 is pressed, the unlocking member 310 can drive the transmission member 320 to move to the left, and then the transmission member 320 can drive the locking member 330 to move downward to separate from the positioning insert 532, thereby driving the locking member 330 to unlock, and the connecting support 200 can be separated from the fixing assembly 530. After releasing the unlocking member 310, the transmission member 320 drives the unlocking member 310 to reset, and at the same time, the force acting on the locking member 330 by the transmission member 320 disappears, and the locking member 330 resets to lock the positioning insert 532, and the connecting support 200 is connected to the fixing assembly 530.

[0061] It is worth noting that the specific structural form of the main frame 210 and the bracket seat 220 is not limited in principle, as long as the bracket seat 220 can be set at the end of the main frame 210 and ensure that the main frame 210 and the bracket seat 220 can install the transmission member 320 and the unlocking member 310. Exemplarily, the main frame 210 is a hollow rod-shaped structure, and the bracket seat 220 is sleeved on the end of the main frame 210.

[0062] See also Figure 1 In one embodiment, the transmission member 320 includes a trigger shaft 321 and a trigger elastic member 322. The trigger shaft 321 is movably disposed in the connecting bracket 200. The trigger elastic member 322 is sleeved on the trigger shaft 321 and connects the trigger shaft 321 and the connecting bracket 200. One end of the trigger shaft 321 abuts against or disengages from the locking member 330, and the other end of the trigger shaft 321 is connected to the unlocking member 310. The trigger elastic member 322 is sleeved on the trigger shaft 321, and one end of the trigger elastic member 322 abuts against the trigger shaft 321, and the other end abuts against the connecting bracket 200. The elastic force of the trigger elastic member 322 can keep the trigger shaft 321 in the initial position, that is, the trigger shaft 321 does not touch the locking member 330 according to Figure 1 The paper direction shown is moving downward.

[0063] When the unlocking member 310 is pressed, the unlocking member 310 drives the trigger shaft 321 to move, and then the trigger shaft 321 moves to overcome the elastic force of the trigger elastic member 322 to compress the trigger elastic member 322. At this time, the trigger shaft 321 moves to the left and abuts against the locking member 330. When the trigger shaft 321 continues to move, it drives the locking member 330 to move so that the locking member 330 is separated from the positioning insert 532, and the locking member 330 is unlocked from the positioning insert 532. After releasing the unlocking member 310, the trigger shaft 321 is no longer affected by external force, and the elastic force of the trigger elastic member 322 drives the trigger shaft 321 and the unlocking member 310 to reset. At this time, the trigger shaft 321 moves to the right and gradually releases the locking member 330, so that the locking member 330 is locked with the positioning insert 532. Figure 1 Move upward as shown in the middle paper to reset.

[0064] Optionally, the trigger elastic member 322 is a spring. Optionally, the trigger shaft 321 has a limiting step, and the limiting step abuts against one end of the trigger elastic member 322. In other words, the trigger shaft 321 is arranged in a stepped shape, and the trigger elastic member 322 is sleeved on the trigger shaft 321, and one end of the trigger elastic member 322 abuts against the limiting step, so as to limit the trigger elastic member 322 in one direction.

[0065] See also Figure 1 In one embodiment, the connecting bracket 200 further includes a fixing seat 230, which is disposed in the main bracket 210 and located at one end of the main bracket 210, and the fixing seat 230 abuts against the triggering elastic member 322. That is, the present application sets a fixing seat 230 in the main bracket 210, and through the cooperation between the fixing seat 230 and the limiting step, it is convenient to install the trigger shaft 321 and also to limit the triggering elastic member 322, so that the triggering elastic member 322 can reset the trigger shaft 321 to ensure that the locking member 330 is reliably locked.

[0066] See also Figure 1 In one embodiment, the locking member 330 includes a locking tongue 331 and a locking elastic member 332. The locking tongue 331 is arranged on the connecting bracket 200. The connecting bracket 200 has a through hole on the circumference for the locking tongue 331 to move in and out. The trigger shaft 321 drives the locking tongue 331 to move into the connecting bracket 200 to unlock the locking member 330 and the fixing assembly 530. The locking elastic member 332 elastically connects the locking tongue 331 and the connecting bracket 200, so as to make the locking tongue 331 extend out of the connecting bracket 200.

[0067] like Figure 1As shown, the trigger shaft 321 moves in the left-right direction, the locking member 330 moves in the up-down direction, and the connecting bracket 200 has a through hole on the top. When the locking tongue 331 is clamped in the positioning insert 532, locking is achieved, and when the locking tongue 331 is separated from the positioning insert 532, unlocking is achieved. When the locking tongue 331 is locked in the positioning insert 532, the locking elastic member 332 can keep the locking tongue 331 in a locked state, thereby keeping the locking tongue 331 always in contact with the positioning insert 532. Optionally, the through hole is a hole or a notch that can achieve locking.

[0068] Specifically, after the trigger shaft 321 moves to the left, the trigger shaft 321 can push the lock tongue 331 to move downward (such as Figure 1 As shown in the figure, the lock tongue 331 overcomes the elastic force of the locking elastic member 332 and moves into the connecting bracket 200 through the hole. At this time, the lock tongue 331 is separated from the positioning insert 532 to achieve unlocking. After the trigger elastic member 322 drives the trigger shaft 321 to reset, the trigger shaft 321 is separated from the pressure on the lock tongue 331, and the elastic force of the locking elastic member 332 pushes the lock tongue 331 to reset. At this time, the lock tongue 331 extends out through the hole and is clamped to the positioning insert 532 to achieve locking.

[0069] Optionally, the locking elastic member 332 is a spring. Optionally, the end of the locking tongue 331 away from the positioning insert 532 has a groove, and the locking elastic member 332 is located in the groove, with one end thereof abutting against the locking tongue 331 and the other end thereof abutting against the connecting bracket 200. In this way, the elastic force of the locking elastic member 332 can push the locking tongue 331 out of the through hole to abut against the positioning insert 532. Optionally, the unlocking member 310 is an unlocking button.

[0070] In one embodiment, the lock tongue 331 has a lock hook 3312, and the lock hook 3312 can be hooked on the fixing assembly 530 when the lock tongue 331 is locked. In other words, the lock tongue 331 has a lock hook 3312 above it, and the lock hook 3312 can be clamped to the installation position of the fixing assembly 530. The lock tongue 331 is limited by the cooperation between the fixing assembly 530 and the lock hook to prevent the lock tongue 331 from coming out of the installation position, thereby ensuring reliable locking. Optionally, the lock hook 3312 is a protrusion. Of course, in other embodiments of the present application, the lock hook 3312 can also be set in a hook shape.

[0071] See also Figure 1 In one embodiment, the lock tongue 331 has a driving groove 3311, one end of the trigger shaft 321 extends into and abuts the driving groove 3311, and the trigger shaft 321 drives the lock tongue 331 to move into the connecting bracket 200 through the driving groove 3311. When the trigger shaft 321 moves to the left, the trigger shaft 321 abuts the driving groove 3311 to drive the lock tongue 331 to move, so that the lock tongue 331 moves downward to achieve unlocking.

[0072] In one embodiment, the driving groove 3311 has an inclined surface, and the end of the trigger shaft 321 has an inclined surface, and the trigger shaft 321 drives the locking tongue 331 to move into the connecting bracket 200 through the inclined surface. Figure 1 As shown, it is inclined from the lower right to the upper left, that is, facing the positioning insert 532, and when the trigger shaft 321 is in the initial position, its end is aligned with the entrance end of the driving groove 3311. When the trigger shaft 321 moves to the left, the trigger shaft 321 abuts against the inclined surface of the driving groove 3311 and moves along the inclined surface to move the locking tongue 331 downward.

[0073] Of course, the driving groove may also have a wedge block, and the end of the trigger shaft 321 may have a wedge surface, and the left-right movement may be converted into the up-down movement through the cooperation of the wedge surface and the wedge block, so that the lock tongue 331 may be retracted into the connection housing through the through hole. In other embodiments of the present application, the trigger shaft 321 and the lock tongue 331 may also cooperate in other structural forms, as long as the left-right movement may be converted into the up-down movement.

[0074] Optionally, a guide slope 33111 is provided on one end of the lock tongue 331 away from the trigger shaft 321. The guide slope 33111 can guide the lock tongue 331 to be installed in the installation position. When the connecting bracket 200 is not inserted into the installation position, the lock tongue 331 is extended out of the connecting bracket 200. When the connecting bracket 200 is inserted into the installation position, the lock tongue 331 will abut against the positioning insert 532 at the edge of the installation position, and at this time, the positioning insert 532 abuts against the lock tongue 331.

[0075] During the gradual insertion process, the positioning insert 532 overcomes the elastic force of the locking elastic member 332 so that the locking tongue 331 compresses the locking elastic member 332, so that the locking tongue 331 moves through the hole into the connecting bracket 200, so as to facilitate the connecting bracket 200 to be inserted into the installation position. When the connecting bracket 200 is installed in place, the locking tongue 331 is no longer pressed by the positioning insert 532, and the elastic force of the locking elastic member 332 pushes the locking tongue 331 to reset. At this time, the locking tongue 331 extends through the hole and is clamped to the positioning insert 532 to achieve locking.

[0076] See also Figures 1 to 5 In one embodiment, the support structure 10 further includes a support handle 400, and both sides of the support handle 400 are used to connect the blood pump 20 and the oxygenator 30, and / or the support handle 400 is connected to the portable oxygen cylinder 40. The support handle 400 passes through the support seat 220 of the connecting support 200 to be connected to the connecting support 200. The support handle 400 can be used to achieve the installation and fixation of the components to be installed.

[0077] like Figure 4As shown, one end of the stent handle 400 is connected to the oxygenator 30, and the other end of the stent handle 400 is connected to the blood pump 20. Figure 5 As shown, the support handle 400 is connected to the handle of the portable oxygen cylinder 40. That is, the support handle 400 of one support structure 10 connects the blood pump 20 and the oxygenator 30, and the support handle 400 of the other support structure 10 connects the portable oxygen cylinder 40.

[0078] Optionally, the unlocking member 310 is disposed on the bracket handle 400. In this way, it is convenient to operate the unlocking with one hand while grasping the bracket handle 400 to complete the transfer of the equipment installed on the bracket structure 10. For heavier installed equipment, both hands can be used to simultaneously operate to complete the unlocking and transfer purposes. This setting is only intended to combine the unlocking position and the handle position in one place, which is convenient for quick device transfer. Compared with some other embodiments in which the unlocking position is set at a position other than the handle and requires both hands to operate separately, it is more convenient.

[0079] It can be understood that in the present embodiment, the fixing component 530 is arranged on the main unit 50 of the main unit device A and the trolley 60 of the extracorporeal circulatory system B. In other embodiments, the fixing component can also be arranged at the target position of the object to be fixed according to the specific object to be fixed. In this way, the connecting bracket 200 of the bracket structure 10 can be directly plugged and installed into the fixing component 530 of the main unit 50 or the fixing component 530 of the trolley 60, and locked and fixed by the locking component 300. In this way, the bracket structure 10 can directly install the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 on the main unit 50 of the main unit device A, and can also be installed on the trolley 60 of the extracorporeal circulatory system B. Medical staff can select the installation position of the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 according to actual use requirements, and realize the rapid fixation and transfer of the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 through the bracket structure 10.

[0080] like Figure 3 In the illustrated embodiment, interfaces 511 for inserting one end of the connection bracket 200 of the bracket structure 10 are provided on both sides of the handle 510, and the fixing component 530 is located in the interface 511. The fixing component 530 is fixed in the handle 510 or is a part of the handle 510, that is, the fixing housing 531 of the fixing component 530 is provided in the handle 510 or is an integral structure with the housing of the handle 510 of the host 50. In other words, the housing of the fixing component 530 can be the shell of the handle 510 of the host 50.

[0081] By providing interfaces 511 for inserting one end of the connecting bracket 200 on both sides of the handle 510, and the connecting bracket 200 and the bracket handle 400 together form a roughly T-shaped layout, it is convenient to connect the heavy portable oxygen cylinder 40 to one side of the main unit 50 through the connecting bracket 200 during carrying, while the light-weight blood pump 20 and oxygenator 30 are located on the other side of the main unit 50, so that the two sides of the main unit 50 can be kept balanced and convenient to carry. Figure 2 In the embodiment, the fixing assembly 530 is fixed to the trolley 60 , and the fixing housing 531 of the fixing assembly 530 is an integral structure with the corresponding component of the trolley 60 or is arranged in the corresponding component of the trolley 60 .

[0082] See also Figures 1 to 3 When the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 on the trolley 60 need to be transferred to the host 50, the medical staff presses the unlocking member 310 of the locking assembly 300, such as Figure 6 As shown, Figure 6 For one-handed operation Figure 1 Schematic diagram of the bracket structure 10 shown. The unlocking member 310 drives the trigger shaft 321 to drive the locking tongue 331 to compress the locking elastic member 332, so that the locking tongue 331 is separated from the positioning insert 532 on the trolley 60 to achieve unlocking. At this time, the connecting bracket 200 can be pulled out from the installation position of the fixing component 530. Subsequently, the connecting bracket 200 is inserted into the installation position of the fixing component 530 of the host 50. During the insertion of the connecting bracket 200, the locking elastic member 332 is compressed to enable the locking tongue 331 to slide into the installation position. When the locking tongue 331 moves into place, the locking elastic member 332 automatically rebounds, so that the locking tongue 331 is stuck in the positioning insert 532 to achieve locking. The blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 on the host 50 are transferred to the trolley 60 in the same way, which will not be repeated here.

[0083] The support structure 10 of the present application is pluggably installed in the fixing assembly 530 by connecting the support 200, and is locked and unlocked by the cooperation of the locking assembly 300 and the fixing assembly 530. In this way, when the support structure 10 is connected to the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40, the support structure 10 can realize the rapid disassembly and assembly of the oxygenator 30, the blood pump 20 and the portable oxygen cylinder 40, which is convenient for use.

[0084] like Figure 3As shown, in one embodiment, two support structures 10 are symmetrically arranged on the handle 510 and extend to both sides of the host 50. The two support structures 10 are symmetrically arranged at both ends of the handle 510 along the length direction of the handle 510 and extend toward the left and right sides of the handle 510. In this way, after the support structure 10 is connected to the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40, the blood pump 20 and the oxygenator 30 are located on the right side of the host 50, and the portable oxygen cylinder 40 is located on the left side of the host 50. In this way, the weight on both sides of the host 50 can be basically balanced, which is convenient for carrying and avoids falling as much as possible.

[0085] In one embodiment, the host device A further includes a weight component, which is disposed on at least one support structure 10. That is, after the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are mounted on the handle 510 of the host 50 through the support structure 10, a weight can be installed on the support structure 10 to balance the weight on the left and right sides of the host 50, thereby ensuring that the balance of the host 50 is easily maintained when the host 50 is carried, and facilitating the medical staff to carry it.

[0086] In one embodiment, the host 50 also includes a shell assembly, which includes an aluminum alloy liner and a plastic shell, and the plastic shell is sleeved on the outside of the aluminum alloy liner. In other words, the shell of the host 50 adopts a double cover structure. The outer layer is a plastic shell, and the inner layer is an aluminum alloy liner. The lightweight aluminum alloy liner can enable the host 50 to resist a certain degree of mechanical impact, and can also shield electromagnetic interference. The plastic shell can reduce the weight of the device, so that the weight of the medical staff on the device can be greatly reduced during transportation. Moreover, the double cover structure can also make the host 50 have good waterproof performance.

[0087] See also Figure 3 In one embodiment of the present application, the two support structures 10 are respectively a first support structure and a second support structure. Figure 3 In the figure, the right side is the first bracket structure, the left side is the second bracket structure, the fixing components 530 of the first bracket structure and the second bracket structure are arranged on both sides of the handle 510, the connecting bracket 200 of the first bracket structure connects the blood pump 20 and the oxygenator 30, and can be plugged and installed in the fixing component 530 of the first bracket structure, and the connecting bracket 200 of the second bracket connects the portable oxygen cylinder 40, and can be plugged and installed in the fixing component 530 of the second bracket structure. In this way, the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 can be quickly plugged and fixedly installed in the handle 510 of the host 50.

[0088] See also Figure 1 and Figure 2The present application also provides a trolley 60, which is used in an extracorporeal assisted circulation system B. The trolley 60 can cooperate with the host device A in the above embodiment for transportation. The extracorporeal assisted circulation system B also includes a host 50, a blood pump 20, an oxygenator 30, a portable oxygen cylinder 40 and two support structures 10 as in any of the above embodiments. The trolley 60 has a first support structure 610 and a second support structure 620. During use, the first support structure 610 is usually used to place or install the host 50 to facilitate the operation of the host by medical staff. The two support structures 10 are arranged on both sides of the second support structure 620, one of which connects the blood pump 20 and the oxygenator 30, and the other supports 10 connects the portable oxygen cylinder 40.

[0089] The trolley 60 includes a base 650 and a support 660. The bottom of the base 650 has rollers. The support 660 is arranged on the base 650. The first support structure 610 and the second support structure 620 are arranged on the support 660. Optionally, the first support structure 610 and the second support structure 620 are arranged at intervals in the height direction. That is, the first support structure 610 is located at the top, the second support structure 620 is located at the bottom, and there is a certain distance between the first support structure 610 and the second support structure 620. In this way, the host 50 is placed on the first support structure 610, and the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 can be installed on both sides of the second support structure 620. It is worth noting that the structure of the host 50 of this embodiment is substantially the same as that of the host 50 in the above embodiment, which will not be repeated here.

[0090] When it is necessary to use the extracorporeal assisted circulation system B in the hospital, the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are directly installed on the trolley 60 through the support structure 10 to meet the use requirements. Specifically, the fixing assembly 530 is arranged on the second supporting structure 620, the connecting bracket 200 of the support structure 10 and the fixing assembly 530 are directly plugged and installed in the fixing assembly 530, and the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are installed on the trolley 60. When the system needs to be transported in a portable manner, the main unit 50 is removed from the first supporting structure 610, and the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are pulled out and disassembled from the second supporting structure 620 through the support structure 10, and the connecting bracket 200 of the support structure 10 is directly inserted into the fixing assembly 530 on both sides of the handle 510 of the main unit 50. After the transfer and installation is completed, it can be carried.

[0091] See also Figure 2In one embodiment, the trolley 60 also includes a steering structure 670, which includes a steering bracket 671 and a steering seat 672. The steering bracket 671 is arranged on the second support structure 620, and the steering seat 672 is rotatably arranged on the steering bracket 671. The steering seat 672 is connected to one of the support structures 10 and is used to adjust the spatial angle between the blood pump 20 and the oxygenator 30.

[0092] The steering structure 670 is used to steer the support structure 10 connecting the blood pump 20 and the oxygenator 30 to adjust the spatial angle between the blood pump 20 and the oxygenator 30 so that the blood pump 20 and the oxygenator 30 can meet the use requirements. Specifically, the steering structure 670 is disposed between the fixing assembly 530 and the second supporting structure 620, so that the steering structure 670 can adjust the spatial angle between the blood pump 20 and the oxygenator 30 when rotating.

[0093] The steering bracket 671 is arranged at the edge of the second support structure 620, and the steering seat 672 is rotatably arranged at the end of the steering bracket 671 away from the second support structure 620, and the steering seat 672 is connected to the fixing assembly 530. In this way, after the connecting bracket 200 of the support structure 10 is installed to the fixing assembly 530, the steering seat 672 can rotate relative to the steering bracket 671, so that the steering seat 672 can drive the support structure 10 and the blood pump 20 and the oxygenator 30 thereon to rotate, thereby adjusting the spatial angle of the blood pump 20 and the oxygenator 30. Optionally, the steering seat 672 is a universal bracket. The steering seat 672 can rotate in the horizontal plane and the vertical plane, thereby adjusting the spatial angle of the blood pump 20 and the oxygenator 30.

[0094] See also Figure 2 and Figure 7 In one embodiment, the first supporting structure 610 has a positioning pin 611, and the bottom of the host 50 has a positioning hole 520. When the host 50 is installed on the first supporting structure 610, the positioning hole 520 cooperates with the positioning pin 611 for positioning. Figure 7 for Figure 2 The schematic diagram of the placement of the host 50 in the extracorporeal auxiliary circulation system B shown in FIG. The host 50 and the first support structure 610 are limited by the positioning holes 520 and the positioning pins 611 to ensure that the host 50 is reliably fixed and prevent the host 50 from falling from the first support structure 610. Optionally, there are multiple positioning holes 520, and the multiple positioning holes 520 are arranged at intervals. Correspondingly, the position of the positioning pin 611 on the first support structure 610 corresponds to the positioning hole 520 to ensure accurate positioning.

[0095] See also Figure 2 In one embodiment, the extracorporeal assisted circulation system B further includes a heater 80, and the trolley 60 further includes a first saline rack 630, the first saline rack 630 fixes the heater 80, and the heater 80 includes a heat preservation tube.

[0096] The first saline rack 630 is disposed at the base of the trolley 60, and a heater 80 is fixedly mounted on the first saline rack 630, so that the blood in the oxygenator is kept warm by the heater 80. In this way, there is no need to set a large constant temperature water tank on the trolley 60, which reduces the volume and weight of the trolley 60 and facilitates its use.

[0097] In one embodiment, the trolley 60 further includes a second saline rack 640, and the extracorporeal assisted circulation system B further includes an air-oxygen mixer 101, which is fixed to the second saline rack 640. In one embodiment, the extracorporeal assisted circulation system B further includes a fixed oxygen cylinder 90, which is arranged at the rear side of the trolley 60 to ensure sufficient oxygen supply during the operation. In other words, the trolley 60 has both a fixed oxygen cylinder 90 and a portable oxygen cylinder 40, and the portable oxygen cylinder 40 can be pluggably installed on the handle 510 of the main unit 50, which is convenient for use during transportation.

[0098] In one embodiment, the trolley 60 further includes a standby structure 680, which includes a standby bracket 682 and a standby blood pump 20, and the standby blood pump 20 is fixed to the second supporting structure 620 through the standby bracket 682. The standby bracket 682 is connected to the standby blood pump 20 through a rotating shaft and adjusts the angle of the standby blood pump 20.

[0099] See also Figure 2 In another embodiment of the present application, the two support structures 10 are respectively a first support structure and a second support structure. Figure 2 In the figure, the right side is the first support structure, the left side is the second support structure, the fixing components 530 of the first support structure and the second support structure are respectively arranged at the edge of the second support structure 620, the connecting bracket 200 of the first support structure connects the blood pump 20 and the oxygenator 30, and can be plugged and installed in the fixing component 530 of the first support structure, and the connecting bracket 200 of the fourth support connects the portable oxygen cylinder 40, and can be plugged and installed in the fixing component 530 of the second support structure. In this way, the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 can be quickly plugged and fixedly installed to the second support structure 620 of the trolley 60.

[0100] When portable transportation is required, the first bracket structure and the second bracket structure on the trolley 60 are pulled out, and the first bracket structure is inserted into the right side of the handle 510 of the main unit 50 through the connecting bracket 200 and the locking assembly 300 to fix the blood pump 20 and the oxygenator 30 to the right side of the main unit 50, and the second bracket structure is inserted into the left side of the handle 510 of the main unit 50 through the connecting bracket 200 and the locking assembly 300 to fix the portable oxygen cylinder 40 to the left side of the main unit 50. In this way, medical staff can directly hold the handle 510 of the main unit 50 to realize the transportation of the entire system.

[0101] In the present application, the blood pump 20 and the oxygenator 30 are integrated by a support structure 10, and the portable oxygen cylinder 40 is connected by another support structure 10. The two support structures 10 are quickly plugged and unplugged through the connecting bracket 200, the locking component 300 and the fixing component 530. In this way, the support structure 10 can be quickly installed on the trolley 60 and the handle 510 of the main unit 50, so as to realize the portable transportation of the whole system. While holding the connecting bracket 200, the medical staff presses the unlocking member 310 with the thumb, so as to realize the quick fixing and transfer of the support structure 10 between the main unit 50 and the trolley 60 by one-hand operation.

[0102] Moreover, after adopting the support structure 10, the treatment application scenario of the extracorporeal circulatory system B can be extended from only use in the hospital to inter-hospital transfer, outdoor first aid, etc. The host device A has the characteristics of miniaturization, and the portable design can meet the emergency treatment in the community, disaster area, battlefield and transfer between hospitals. It has a wide range of use occasions and can achieve fast transfer.

[0103] The present application also provides a transport method, which uses the stent structure 10 of any of the above embodiments, the host device A of any of the above embodiments, and / or the extracorporeal assisted circulation system B of any of the above embodiments, and the transport method comprises the following steps:

[0104] When portable transportation is required, the two parts of the support structure 1 are connected to the two fixing components 530 of the host device A respectively;

[0105] Two connecting brackets 200 are arranged on both sides of the handle 510 of the main unit 50. The connecting brackets of each bracket structure 100 are connected to at least one functional component, so that the functional components are distributed on both sides of the main unit 50 and maintained in balance for portable transportation.

[0106] The present application can realize the transfer of the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 between the host device A and the extracorporeal assisted circulation system B through the support structure 10. When the host device A is adjusted to the extracorporeal assisted circulation system B, the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are directly pulled out from the fixed component 530 corresponding to the host 50 through the connecting bracket 200, and then installed in the fixed component 530 corresponding to the trolley 60 to meet the use requirements. When portable transportation is required, the blood pump 20, the oxygenator 30 and the portable oxygen cylinder 40 are pulled out from the fixed component 530 corresponding to the trolley 60 through the connecting bracket 200, and then installed in the fixed component 530 corresponding to the host 50.

[0107] Moreover, after the two support structures 10 are connected to the corresponding fixing components 530 through the connecting brackets 200, they are symmetrically arranged on both sides of the handle 510 of the host 50. Moreover, the two connecting brackets 200 can be connected to the same or different functional components on both sides of the host 50 to maintain balance and then transport.

[0108] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0109] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
