An embodiment of the organ cassette adapter assembly according to the invention is explained in detail below with reference to fig. 1 to 11.

In the present embodiment, as shown in fig. 1 to 11, the organ cassette adapter assembly according to the present invention includes a first adapter 1, a flexible tube 2, an intermediate connection assembly 3, and a second adapter 4. The first connector 1 has an exhaust port 11 for exhausting air, a hose connection portion 12 and a pipe interface 13, the exhaust port 11 is used for exhausting gas in an organ or exhausting gas in a circulation loop for maintaining the activity of the organ (such as heart, lung, kidney, etc.), the pipe interface 13 is used for connecting an organ box drain pipe (not shown in the figure) through a pipe assembly to form a circulation loop, so that the activity of the organ can be maintained, and meanwhile, the third connector 52 also conveys waste liquid collected in the organ box to the circulation loop. The intermediate connection assembly 3 is connected to the hose connection part 12 via the hose 2 and is provided with a first locking element 31. One end of the second connector 4 is in plug fit with the middle connecting component 3, and the other end is used for connecting an artery or vein of an organ. The second connector 4 is locked to the intermediate connection assembly 3 by means of a first locking member 31. The intermediate connector assembly 3 is also connectable to a connector of the organ cassette outlet conduit within the organ cassette during priming via an auxiliary connector, the auxiliary connector also forming a quick-connect connection with the intermediate connector assembly 3.

Through adopting above-mentioned technical scheme, can use the breakout tongs to press from both sides the hose tight after the return circuit pre-charge is exhausted and is accomplished, and then can prevent that the air from being pushed back in the organ under the liquid effect, the hose can be according to the size of organ simultaneously, adaptability ground adjustment bend angle, thereby make not unidimensional organ can settle in the organ box more supple and more, after the organ is accomplished settling at the organ box, can also push the liquid that contains the bubble towards gas vent 11 through the breakout tongs, make the bubble discharge from gas vent 11, the air in the circulation pipeline is discharged better, ensure circulation pipeline's normal work. Simultaneously, through adopting the hose, when organ box joint assembly installed organ box in order to connect the organ, need not set up the pipeline of buckling in order to stride some steps again, just also further avoided buckling the risk that pipeline department formed the thrombus, can improve the security and the reliability that the organ maintained. Finally, the middle connecting assembly and the second connector are matched in a plug-in mode instead of the existing threaded connection mode, the connecting mode is simple and convenient, the hose can be prevented from being twisted and bent due to the fact that the threaded connection mode is adopted, and stability and reliability of the hose are guaranteed.

In one embodiment, as shown in fig. 3, the first joint 1 is formed with a bent portion 14, and the exhaust port 11 is located between the hose connecting portion 12 and the pipe joint 13 and is provided on one side of the bent portion 14.

In one embodiment, the hose connection 12 can be configured as a pagoda joint, which facilitates a quick plug-in mounting of the hose 2 with good sealing properties.

In one embodiment, the first locking member 31 has a first operating position and a second operating position. Wherein the first locking member 31, when in the first operative position, limits the disengagement of the second joint 4 from the intermediate connection assembly 3 and, when in the second operative position, the first locking member 31, allows the disengagement of the second joint 4 from the intermediate connection assembly 3.

In one embodiment, as shown in fig. 2, the intermediate connection assembly 3 further includes a first elastic member 32 and a first operating member 33. The first elastic member 32 and the first operating member 33 are both connected to the first locking member 31, pressing the first operating member 33 can drive the first locking member 31 to move to the second working position (as shown in fig. 2) against the elastic force of the first elastic member 32, and after the external force applied to the first operating member 33 is removed, the compressed first elastic member 32 applies an elastic force to the first locking member 31 to move the first locking member 31 from the second working position to the first working position and keep the first locking member at the first working position, and at this time, the first locking member 31 locks the second connector 4 to prevent the second connector from being separated from the intermediate connection assembly 3. It will be appreciated that the initial position of the first locking member 31, after it is installed in the intermediate connection module 3, may be the same position as the first working position or a different position before the second connector 4 is plugged into the intermediate connection module 3.

In an embodiment, after the first locking member 31, the first elastic member 32 and the first operating member 33 are assembled, the first elastic member 32 is in a compressed state, and a limiting structure (not shown) may be provided to limit the first locking member 31 or the first operating member 33, so as to prevent the first locking member 31 or the first operating member 33 from being disengaged from the middle connecting assembly 3 due to the force of the first elastic member 32.

In another embodiment, the first elastic member 32 may not be provided, and the first locking member 31 may be directly operated and moved by the first operating member 33, so that the first locking member 31 is switched between the first operating position and the second operating position. Further, when the first locking member 31 is in the first working position, a locking structure (not shown) may be additionally provided to lock the first operating member 33, so as to prevent the first operating member 33 from being accidentally operated to move the first locking member 31 and unlock the second connector 4.

It is understood that, in another embodiment, the first operating member 33 may not be provided, and the first locking member 31 and the first elastic member 32 may be provided only to complete the locking of the second connector 4. Specifically, an actuating surface (e.g., an inclined surface or a curved surface) may be formed on the second connector 4 and/or the first locking member 31, the second connector 4 and the first locking member 31 are in contact through the actuating surface during the process of inserting the second connector 4 into the intermediate connection assembly 3, the second connector 4 applies force to the first locking member 31 through the actuating surface, so that the first locking member 31 compresses the first elastic member 32 and moves to the second working position, and after the second connector 4 is installed in place, the first locking member 31 moves to the first working position under the elastic force of the first elastic member 32 to lock the second connector 4. In this embodiment, the second connector 4 can achieve direct plug-in automatic locking without providing an additional operation of the first operation member 33. This embodiment is simple to operate, but relatively laborious and relatively inconvenient to manufacture and install, compared to the embodiment in which the first operating member 33 is provided.

Further, a similar construction principle can also be used to achieve direct detachment of the second joint 4. That is, another actuating surface may be formed on the second connector 4 and/or the first locking member 31, and when the second connector 4 is directly pulled down and detached, the second connector 4 applies force to the first locking member 31 through the actuating surface, so that the first locking member 31 compresses the first elastic member 32 and moves to the second working position, and at this time, the second connector 4 can be detached smoothly. In this embodiment, the overall operation is simpler, the first operation element 33 does not need to be operated additionally, but the locking stability of the second joint 4 is somewhat deficient, and if the second joint 4 is prevented from being disengaged from the middle connection assembly 3 when being accidentally stressed in order to improve the locking stability of the second joint 4, the force required for detaching the second joint 4 needs to be increased (for example, by increasing the elastic rigidity of the second elastic element 32), which in turn makes the detachment of the second joint 4 relatively laborious.

In one embodiment, when the second connector 4 is removed in a direction opposite to the plugging direction of the second connector 4 in a state where the second connector 4 is locked, the force applied to the first locking member 31 by the second connector 4 is perpendicular to the direction of the first locking member 31 moving from the first working position to the second working position. Therefore, the installation stability of the second joint 4 can be ensured, and the second joint 4 is prevented from being accidentally separated from the middle connecting component 3 under the action of external force, so that adverse effects are avoided. It is added that in this embodiment, the first operating member 33 is provided to facilitate the active operation to move the first locking member 31 from the first operating position to the second operating position, so as to enable the second joint 4 to be removed for maintenance or replacement; if the above-described embodiment in which the first operation member 33 is not provided is adopted, it will be difficult to detach the second connector 4.

In one embodiment, as shown in fig. 2 and 4, the first locking member 31 includes a first annular portion 311, a first connection portion 312, and a second connection portion 313. The first annular portion 311 is used to lock the second connector 4, the first connection portion 312 and the second connection portion 313 are located at two radial sides of the first annular portion 311, the first elastic member 32 is sleeved on the first connection portion 312, and the second connection portion 313 is connected to the first operating member 33. Specifically, the first locking member 31 is not limited to the first annular portion 311 for locking the second joint 4, and a bent rod-shaped structure or other structures may be used for locking the second joint 4.

In one embodiment, as shown in fig. 4, the first annular portion 311 is formed with a first limiting plane 3111, and the first limiting plane 3111 is perpendicular to the inserting direction of the second connector 4. Thus, after the second joint 4 is plugged into the middle connection assembly 3, the second joint 4 contacts the first locking element 31 through the first limiting plane 3111, and when the second joint 4 is detached in a direction opposite to the plugging direction of the second joint 4, the acting force applied to the first locking element 31 by the second joint 4 is perpendicular to the first limiting plane 3111, so that the first locking element 31 cannot be moved from the first working position to the second working position, and the second joint 4 can be prevented from being accidentally detached from the middle connection assembly 3 under the action of external force, thereby causing adverse effects.

Further, as shown in fig. 4, the first annular portion 311 has a first through hole 3112 through which the second contact 4 passes.

In one embodiment, as shown in fig. 5 and 6, the intermediate connection assembly 3 further includes the first housing part 34, and the first housing part 34 includes the connection body portion 341 and the end cap portion 342 connected to each other. The connecting body portion 341 and the end cap portion 342 may be connected by a fastener, a snap, or other methods, or may be integrally formed, which is not limited in the present invention.

In one embodiment, as shown in fig. 6 to 8, the first housing part 34 has an installation guide groove 343, the first operating piece 33 is partially disposed in the installation guide groove 343, and the installation guide groove 343 can guide and limit the movement of the first operating piece 33. Of course, it should be understood that the first operating member 33 may be entirely disposed in the mounting guide groove 343.

In one embodiment, as shown in fig. 6 and 8, the first housing portion 34 is formed with a first cavity 344, and the first cavity 344 is enclosed by the connecting body portion 341 and the end cap portion 342. Wherein the first locking member 31 is partially disposed in the first cavity 344, the first locking member 31 is slidable in the first cavity 344 to switch between the first operating position and the second operating position. Of course, the first locking member 31 may also be disposed entirely within the first cavity 344.

In one embodiment, as shown in fig. 2 and 6, the first housing part 34 is formed with a connection hole 345, and one end of the second connector 4 is inserted into the connection hole 345 in an axial direction of the connection hole 345. Wherein, the sliding movement direction of the first locking member 31 is perpendicular to the axial direction of the connection hole 345.

In one embodiment, as shown in fig. 2 and 6, the first housing portion 34 is formed with a connector 346, and one end of the hose 2 is sleeved with the connector 346. Wherein the connection head 346 can be configured as a pagoda joint, which facilitates a quick plug-in mounting of the hose 2 and has good connection tightness. Further, the pagoda joint can be directly formed at the upper end of the first housing part 34 and extend along the axial direction of the first housing part 34, which makes the intermediate connection assembly 3 simple in overall structure, easy to manufacture, and more convenient to connect the hoses 2.

In one embodiment, as shown in fig. 2, 9 and 10, the outer peripheral wall of the second tab 4 is formed with a first locking groove 41. Wherein the first locking member 31 is partially inserted into the first locking groove 41 to lock the second connector 4 in the first working position, and specifically, in an embodiment, the first annular portion 311 is partially inserted into the first locking groove 41 to lock the second connector 4. Of course, the present invention is not limited thereto, and the first locking member 31 may be completely inserted into the first locking groove 41.

In one embodiment, as shown in fig. 2 and 9, the outer peripheral wall of the second joint 4 is formed with a seal groove 42. A seal ring is provided in the seal groove 42 to improve the sealing property of the connection between the second joint 4 and the first housing portion 34. Optionally, there are at least two seal grooves 42, and at least two seal rings are correspondingly disposed.

In one embodiment, as shown in fig. 2 and 9, the peripheral wall of the second connector 4 is formed with an annular groove 43, the annular groove 43 being adapted to be fittingly connected to an artery or vein of an organ. Wherein, the quantity of ring channel 43 can be a plurality of, and a plurality of ring channels 43 can arrange the setting closely, and this is favorable to increasing the contact surface between artery or vein and second joint 4, strengthens frictional force and leakproofness effect, prevents that blood from revealing.

The connection process between the second joint 4 and the intermediate connection assembly 3 is briefly described below.

First, the main body portion 341, the end cap portion 342, the first locking member 31, the first elastic member 32, and the first operating member 33 are assembled together. At this time, the first locking member 31 and the first operating member 33 are both in the initial position, the projections of the first annular portion 311 and the connection hole 345 in the axial direction of the connection hole 345 have an overlapping portion, the first annular portion 311 blocks the insertion of the second joint 4 into the connection hole 345, the first elastic member 32 is in a compressed state, one end thereof is connected to the inner wall surface of the first housing portion 34, and the other end thereof is connected to the first locking member 31.

When the second connector 4 is ready to be mounted, the first operating member 33 is pressed, so that the first locking member 31 is moved to the second operating position. At this time, the central axes of the first through hole 3112 of the first ring portion 311 and the connection hole 345 may coincide, projections of both the first ring portion 311 and the connection hole 345 in the axial direction of the connection hole 345 do not overlap, and the second connector 4 may be inserted into the connection hole 345.

Further, after the external force applied to the second connector 4 is removed, the first locking member 31 is moved from the second working position to the first working position by the first elastic member 32, that is, the first annular portion 311 is partially inserted into the first locking groove 41, thereby locking the second connector 4. At this point, the second connector 4 and the intermediate connection assembly 3 are connected.

The process of removing the second connector 4 is exactly the reverse of the installation process and will not be described here.

The present invention also provides an organ transport platform comprising an organ cassette 5, as shown in fig. 11. Wherein, a positioning groove (not shown in the figure) is provided in the side wall 51 of the organ cassette 5, the first connector 1 is provided with a positioning portion 15, and the first connector 1 is connected to the organ cassette 5 by the cooperation of the positioning portion 15 and the positioning groove, so that the first connector 1 can be prevented from rotating relative to the organ cassette 5, and the first connector 1 can be glued and fixed to the organ cassette 5.

Further, the organ cassette 5 is provided with a third joint 52, and one end of the third joint 52 is communicated with a waste liquid collecting tank for collecting waste liquid (blood flowing out from the left ventricle opening, priming liquid, and the like) in the organ cassette and sending the waste liquid to the circulation circuit.

Wherein the bearing seat 61 is used for placing a device (such as an organ box) containing organs, one end of the supporting upright 62 is connected with the bearing seat 61, one end of the cross arm 63 is connected with the supporting upright 62 in a sliding way so as to be capable of moving up and down relative to the supporting upright 62 to adjust the position, and the other end is connected with the auxiliary connecting component 7.

In one embodiment, as shown in fig. 13, the connection auxiliary member 7 includes a second housing portion 71, and the second housing portion 71 is formed with a positioning hole 711 into which the second connector 4 is inserted. Wherein the positioning hole 711 may be a through hole having a diameter sized to allow the second connector 4 to be vertically inserted therein from above and to allow the second connector 4 to be removed from the positioning hole 711 by being moved downward. Of course, the present invention is not limited thereto, and the second contact 4 may also be inserted into the positioning hole 711 from below to above and be moved downward out of the positioning hole 711, in which case the positioning hole 711 may also be configured as a blind hole whose upper end is closed, and need not be provided as a through hole, and alternatively, the positioning hole 711 may also be configured such that the diameter of the upper end portion is smaller than the maximum diameter of the second contact 4, so that the second contact 4 cannot be inserted vertically into the positioning hole 711 from above to below.

In one embodiment, as shown in fig. 14, the connection assist assembly 7 includes a second lock 72, and the second lock 72 is provided in the second housing portion 71, which is capable of switching movement between the third operating position and the fourth operating position. Wherein, the second locking member 72 restricts the second joint 4 inserted into the positioning hole 711 from being disengaged from the positioning hole 711 when in the third working position, for positioning the second joint 4 to assist the connection of the second joint 4 with the organ; second locking member 72 allows second connector 4 inserted into positioning hole 711 to move toward the organ out of positioning hole 711 in the fourth operation position.

Through adopting above-mentioned technical scheme, use to connect the locating component to connect 4 location fixed with the second, only need an operator can connect 4 with the second with the organ to be connected, and is simple and convenient, and the connection process is stable.

In one embodiment, as shown in fig. 14, the connection auxiliary assembly 7 further includes a second elastic member 73, and the second elastic member 73 is connected to the second locking member 72 for moving the second locking member 72 from the fourth working position to the third working position and keeping the second locking member at the third working position. Wherein the second elastic member 73 may be a spring.

In one embodiment, as shown in fig. 9 and 14, the outer wall of the second connector 4 is formed with a first inclined surface 44, and the second locking member 72 is formed with a second inclined surface 721. Here, in the initial state, the second locking member 72 partially extends into the positioning hole 711, and the second inclined surface 721 is also located in the positioning hole 711. As shown in fig. 15, when the second connector 4 is inserted into the positioning hole 711 from top to bottom, the first inclined surface 44 of the second connector 4 contacts the second inclined surface 721 of the second locking member 72, and the second connector 4 will apply a force to the second locking member 72 through the contact between the first inclined surface 44 and the second inclined surface 721, so that the second locking member 72 compresses the second elastic member 73 to move to the fourth working position along the radial direction of the positioning hole 711. Further, when the second connector 4 continues to move downward to the predetermined position, the second locking groove 45 on the second connector 4 is opposite to the second locking piece 72, and the second locking piece 72 will move to the third working position under the elastic force of the second elastic piece 73, i.e. the second locking piece 72 is partially inserted into the second locking groove 45 to lock the second connector 4 in position, and the final state is shown in fig. 16. Of course, the present invention is not limited thereto, and the second locking piece 72 may be designed in a structure that can be completely inserted into the second locking groove 45.

It should be added that it is not necessary that both the second connector 4 and the second locking member 72 be beveled at the same time to achieve the force transmission, and one of the second connector 4 and the second locking member 72 be beveled to achieve the force transmission. Furthermore, the ramp may be replaced by a curved or other form of actuating surface to effect force transfer, and need not be a ramp.

In another embodiment, the second locking groove 45 may not be formed on the second tab 4, and as long as a stepped portion is formed, the second locking piece 72 may be engaged with the stepped portion (for example, the upper surface of the second locking piece 72 supports the stepped surface of the stepped portion) to support and position the second tab 4, preventing the second tab 4 from being downwardly separated from the positioning hole 711.

In one embodiment, as shown in fig. 14 to 17, the connection auxiliary assembly 7 further includes a second operating member 74, and the second operating member 74 is connected to the second locking member 72. The second locking member 72 can be moved from the third working position to the fourth working position against the elastic force of the second elastic member 73 by operating the second operating member 74, and at this time, the second connector 4 can be moved downward to be separated from the positioning hole 711.

In another embodiment, the second operating element 74 may not be provided, when the second locking element 72 is partially inserted into the second locking groove 45 to lock the second connector 4, the second connector 4 and the second locking element 72 may be contacted through an actuating surface (not shown), at this time, a certain external force is applied to the second connector 4 to cause the second connector 4 to move downwards, the second connector 4 applies a force to the second locking element 72 through the actuating surface to cause the second locking element 72 to move in the radial direction to the fourth working position, and the second connector 4 may move downwards to be separated from the positioning hole. It is understood that the actuating surface may be formed on at least one of the second locking element 72 and the second connector 4, and may be in the form of a ramp, a curved surface, or other configurations. It will be appreciated that in this embodiment, the second operating member 74 is omitted, so that operation is simpler, but the stability of the locking is somewhat compromised because the second connector 4 will automatically unlock under certain external forces.

In one embodiment, when second locking member 72 is located at the third working position to lock second connector 4, the force applied to second locking member 72 by second connector 4 is perpendicular to the direction of second locking member 72 moving from the third working position to the fourth working position (i.e., the radial direction of positioning hole 711). Thus, the locking stability of the second joint 4 can be improved, and the second joint 4 is prevented from accidentally separating from the positioning hole 711 under the action of external force, so that adverse effects are avoided. It will be appreciated that in this embodiment, the second operating member 74 must be provided for enabling the second locking member 72 to move from the third operating position to the fourth operating position for unlocking the second connector 4, and it is difficult to remove the second connector 4 without providing the second operating member 74.

It should be noted that the second locking member 72 is not limited to the second annular portion 722 for locking the second connector 4, and a bent rod-shaped structure or other structures may be used for locking the second connector 4.

In one embodiment, as shown in fig. 17 and 18, the second annular portion 722 is formed with a second limit flat 7221, and the second limit flat 7221 is perpendicular to the insertion direction of the second connector 4. Thus, after the second joint 4 is inserted into the positioning hole 711, the second joint 4 contacts the second locking member 72 through the second limiting plane 7221, and the acting force applied to the second locking member 72 by the second joint 4 is perpendicular to the second limiting plane 7221, so that the first locking member 31 cannot be moved from the first working position to the second working position, and further the second joint 4 can be prevented from accidentally disengaging from the middle connection assembly 3 under the action of external force, which causes adverse effects.

Further, the second annular portion 722 has a second through hole 7222 through which the second joint 4 passes.

In one embodiment, as shown in fig. 17, the second housing part 71 further includes a limiting portion 712, and the limiting portion 712 abuts against the second locking member 72 for preventing the second locking member 72 from being separated from the second housing part 71. The limiting portion 712 is located between the second annular portion 722 and the second operating element 74. It should be understood that the present invention is not limited to the specific structure and the arrangement position of the limiting portion, as long as the second locking member 72 can be limited to prevent from being separated from the second housing portion 71.

In one embodiment, as shown in fig. 17, the second housing portion 71 further includes a second cavity 713, the second latch 72 is partially disposed in the second cavity 713, and the second latch 72 is slidable in the second cavity 713 to switch between the third operating position and the fourth operating position. Second locking member 72 may also be disposed entirely within second chamber 713.

Further, the second housing portion 71 includes an upper housing portion 714 and a lower housing portion 715, and the upper housing portion 714 and the lower housing portion 715 are fixedly connected and enclose a second chamber 713.
