Detailed implementation manners

[0028] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following will describe in detail the specific implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] Refer to Figure 1 , Figure 2 and Figure 8 , Figure 1 show a schematic structural diagram of a power source assembly 100 of a medical ex vivo organ mechanical perfusion device according to an embodiment of the present invention, Figure 2 show an exploded schematic diagram of a power source assembly 100 of a medical ex vivo organ mechanical perfusion device according to an embodiment of the present invention, Figure 8 show a schematic structural diagram of a medical ex vivo organ mechanical perfusion device according to an embodiment of the present invention. A power source assembly 100 of a medical ex vivo organ mechanical perfusion device provided by an embodiment of the present invention includes: a mounting plate 110, a centrifugal pump 120, and a peristaltic pump 130. The mounting plate 110 is used to be installed on a main body 200 of the medical ex vivo organ mechanical perfusion device. Both the centrifugal pump 120 and the peristaltic pump 130 are installed on the mounting plate 110, and the peristaltic pump 130 and the centrifugal pump 120 are arranged at intervals.

[0030] For the power source assembly 100 of the above-mentioned mechanical perfusion device for medical ex vivo organs, since both the centrifugal pump 120 and the peristaltic pump 130 are installed on the mounting plate 110, and the centrifugal pump 120, the peristaltic pump 130 and the mounting plate 110 are all installed on the mainframe 200 of the mechanical perfusion device for medical ex vivo organs, instead of separately arranging the centrifugal pump 120 and the peristaltic pump 130 and setting them on other devices, it can reduce the volume of the mechanical perfusion device for medical ex vivo organs, reduce the occupied space, and at the same time, the installation operation is relatively convenient; in addition, the distances from both the centrifugal pump 120 and the peristaltic pump 130 to the container sleeve 300 are relatively close, making it easier to connect pipes and wires, and they are relatively neat, avoiding the phenomenon of messy pipe and wire connections.

[0031] Please refer to Figure 1 and Figure 2 , further, the centrifugal pump 120 includes a power component 121 and a pump head 122. The power component 121 is installed on the mounting plate 110, the pump head 122 is detachably installed on the mounting plate 110, and the power component 121 is used to drive the impeller 1221 in the pump head 122 to rotate. When the power component 121 drives the impeller 1221 in the pump head 122 to rotate, the impeller 1221 can provide power to make the perfusion liquid circulate in the main path. The pump head 122 is a disposable consumable, and since it is detachably installed on the mounting plate 110, it is convenient to replace.

[0032] Please refer to Figures 2 to 4 , Figure 3 shows a schematic structural diagram of the pump head 122, the auxiliary plate 112, the card seat 140, and the movable clamping assembly 150 of the power source assembly 100 of the mechanical perfusion device for medical ex vivo organs according to an embodiment of the present invention, Figure 4 shows Figure 3 exploded schematic diagram. In one embodiment, the power source assembly 100 of the mechanical perfusion device for medical ex vivo organs further includes a card seat 140 and a movable clamping assembly 150. The card seat 140 is installed on the mounting plate 110, and the card seat 140 abuts against one side of the pump housing 1222 of the pump head 122. The movable clamping assembly 150 is movably arranged on the mounting plate 110, and the movable clamping assembly 150 abuts against or separates from the other side of the pump housing 1222. When the card seat 140 abuts against one side of the pump housing 1222 and the movable clamping assembly 150 abuts against the other side of the pump housing 1222, the pump housing 1222 of the pump head 122 can be fixed on the mounting plate 110; when the movable clamping assembly 150 separates from the other side of the pump housing 1222, the card seat 140 and the movable clamping assembly 150 no longer clamp and fix the pump housing 1222 of the pump head 122, and the pump head 122 can be removed.

[0033] It can be understood that the detachable installation method of the pump head 122 on the mounting plate 110 can also adopt other methods, such as realizing the detachable installation of the pump head 122 on the mounting plate 110 by means of installation parts such as bolts, screws, pins, and clamping parts. This embodiment does not limit it here.

[0034] Please refer to Figures 5 to 7 , Figure 5 which shows Figure 3 a structural diagram of one perspective after removing the auxiliary plate 112 in Figure 6 which shows Figure 3 a structural diagram of another perspective after removing the auxiliary plate 112 in Figure 7 which shows Figure 6 a cross-sectional view taken along A-A. In one embodiment, a first recess 1223 is wound around the side wall of the pump housing 1222. The clamping seat 140 is provided with a first convex body 141, and the first convex body 141 extends into the first recess 1223, and the first convex body 141 abuts against the wall of the first recess 1223. The movable clamping assembly 150 is provided with a second convex body 151, and the second convex body 151 extends into the first recess 1223, and the second convex body 151 abuts against the wall of the first recess 1223. In this way, the first convex body 141 and the second convex body 151 respectively abut against the opposite sides of the pump housing 1222, and the first convex body 141 and the second convex body 151 respectively extend into the first recess 1223, so that the fixing effect on the pump housing 1222 is better, and the pump housing 1222 is prevented from moving in the horizontal or vertical direction. In addition, in order to improve the stability effect, the end wall surface of the first convex body 141 is an arc surface adapted to the bottom wall of the first recess 1223, and the end wall surface of the second convex body 151 is an arc surface adapted to the bottom wall of the first recess 1223; the side wall surface of the first convex body 141 is a shape adapted to the side wall of the first recess 1223, and the side wall surface of the second convex body 151 is a shape adapted to the side wall of the first recess 1223, so that the contact surfaces between the first convex body, the second convex body and the pump housing 1222 are increased. In another embodiment, the diameter of the end wall surface of the first convex body 141 is smaller than the diameter of the bottom wall arc surface of the first recess 1223. In addition, the diameter of the end wall surface of the second convex body 151 is smaller than the diameter of the bottom wall arc surface of the first recess 1223. In this way, when the second convex body 151 applies pressure on the side wall of the pump housing 1222, the clamping effect on the pump housing 1222 is relatively stable.

[0035] Please refer to Figures 5 to 7In one embodiment, a positioning shaft 142 is provided on the side of the card holder 140 facing the pump housing 1222, a positioning groove 1224 corresponding to the positioning shaft 142 is provided on the side of the pump housing 1222, and the positioning shaft 142 is installed in the positioning groove 1224. Alternatively, a positioning groove 1224 is provided on the side of the card holder 140 facing the pump housing 1222, a positioning shaft 142 corresponding to the positioning groove 1224 is provided on the side of the pump housing 1222, and the positioning shaft 142 is installed in the positioning groove 1224. In this way, when the positioning shaft 142 is installed in the positioning groove 1224 on the side of the pump housing 1222, the positioning shaft 142 can prevent the pump housing 1222 from rotating, and the positioning effect of the pump housing 1222 is better. Specifically, a plurality of positioning grooves 1224 are circumferentially spaced on the side of the pump housing 1222, and there are one or two positioning shafts 142. In this way, when the pump housing 1222 is installed on the mounting plate 110, the positioning shaft 142 can be installed into one or two positioning grooves 1224, and the installation operation is relatively convenient.

[0036] See also Figures 5 to 7 In one embodiment, the movable clamping assembly 150 includes a guide rail 152, a slider 153, an elastic member 154 and a contact block 155. The guide rail 152 is fixedly arranged on the mounting plate 110, and the guide rail 152 and the clamping seat 140 are arranged at a relative interval. The slider 153 is movably arranged on the guide rail 152, and the slider 153 is connected to the contact block 155. The contact block 155 is used to contact the pump housing 1222. The slider 153 is connected to the guide rail 152 through the elastic member 154. In this way, the slider 153 pushes the contact block 155 under the elastic force of the elastic member 154, so that the contact block 155 contacts the side wall of the pump housing 1222, which has a better clamping effect on the pump housing 1222. When the pump head 122 needs to be disassembled, it is only necessary to move the slider 153 along the guide rail 152. The slider 153 overcomes the force of the elastic member 154 to separate the abutment block 155 from the pump housing 1222. After the abutment block 155 is separated from the pump housing 1222, the pump head 122 can be removed, and the operation is relatively simple. In addition, during the disassembly and assembly of the pump head 122, it is not necessary to move the clamping assembly 150 in a direction perpendicular to the mounting plate 110 to disassemble and assemble the pump head 122, so that the pump head 122 is suitable for being installed in a relatively narrow space, because in a relatively narrow space, it is still convenient to disassemble and assemble the pump head 122. The elastic member 154 is specifically, for example, a spring or an elastic block, which is not limited here. When the slider 153 moves to a position separated from the pump housing 1222, the elastic member 154 can be in a compressed state or a stretched state, which is not limited here.

[0037] In addition, it should be noted that in the infringement comparison, the "slider 153" can be "a part of the abutting block 155", that is, the "slider 153" and the "other parts of the abutting block 155" are integrally formed; or it can be an independent component separable from the "other parts of the abutting block 155", that is, the "slider 153" can be manufactured independently and then combined with the "other parts of the abutting block 155" to form a whole.

[0038] Please refer to Figures 5 to 7 , in one embodiment, the guide rail 152 is provided with a track groove 1521 and a limiting plate 1522 located in the track groove 1521. The slider 153 is movably arranged in the track groove 1521, and the elastic member 154 is connected between the slider 153 and the limiting plate 1522. Specifically, in this embodiment, the limiting plate 1522 is provided with a through hole 1523, the slider 153 is connected with a guide rod 156, the guide rod 156 is movably arranged in the through hole 1523, and the elastic member 154 is a spring sleeved on the guide rod 156. In addition, the second convex body 151 is specifically arranged on the abutting block 155. In addition, it should be noted that in the infringement comparison, the "second convex body 151" can be "a part of the abutting block 155", that is, the "second convex body 151" and the "other parts of the abutting block 155" are integrally formed; or it can be an independent component separable from the "other parts of the abutting block 155", that is, the "second convex body 151" can be manufactured independently and then combined with the "other parts of the abutting block 155" to form a whole.

[0039] Please refer to Figure 2 , in one embodiment, the pump head 122 is detachably mounted on one side surface of the mounting plate 110, and the power assembly 121 is located on the other side surface of the mounting plate 110. The power assembly 121 includes a motor base 1211, a power motor 1212 and a magnetic ring 1213. The motor base 1211 is mounted on the other side surface of the mounting plate 110, the power motor 1212 is mounted on the mounting plate 110, the rotating shaft of the power motor 1212 is connected to the magnetic ring 1213, and when the magnetic ring 1213 rotates, it is used to drive the impeller 1221 in the pump head 122 to rotate.

[0040] Please refer to Figure 2, Further, the mounting plate 110 includes a main body plate 111 and an auxiliary plate 112 connected to the main body plate 111. The auxiliary plate 112 is a non-metal plate. The pump head 122 is mounted on the auxiliary plate 112, and the position of the magnetic ring 1213 corresponds to that of the auxiliary plate 112. When the magnetic ring 1213 rotates, the auxiliary plate 112 will not interfere with the magnetic field of the magnetic ring 1213, and the magnetic ring 1213 can drive the impeller 1221 inside the pump head 122 located on the other side of the auxiliary plate 112 to rotate accordingly. In addition, the main body plate 111 can be either a non-metal plate or a metal plate, which is not limited herein. In this embodiment, the main body plate 111 is a metal plate, such as an aluminum plate, which can ensure the service life.

[0041] Further, a limiting port 1121 is provided on the auxiliary plate 112, a second recess 1111 is provided on the main body plate 111, the limiting port 1121 communicates with the second recess 1111, the guide rail 152 is disposed in the second recess 1111, and the abutting block 155 is located in the limiting port 1121. Thus, the second recess 1111 and the limiting port 1121 have a limiting effect on the moving clamping assembly 150, so that the moving clamping assembly 150 is stably mounted on the mounting plate 110, thereby realizing stable low clamping and fixing of the pump head 122.

[0042] In one embodiment, the mounting method of the card seat 140 on the mounting plate 110, the mounting method of the guide rail 152 on the mounting plate 110, the mounting method of the motor seat 1211 on the mounting plate 110, and the mounting method of the peristaltic pump 130 on the mounting plate 110 are not limited. It can be connected by mounting parts such as screws and bolts, or by mounting methods such as bonding and welding.

[0043] Please refer to Figure 8 , In one embodiment, a medical ex vivo organ mechanical perfusion device includes the power source assembly 100 of the medical ex vivo organ mechanical perfusion device in any of the above embodiments, and further includes a host 200, and the mounting plate 110 is mounted on the host 200.

[0044] For the above-mentioned medical ex vivo organ mechanical perfusion device, since both the centrifugal pump 120 and the peristaltic pump 130 are mounted on the mounting plate 110, and the centrifugal pump 120, the peristaltic pump 130 and the mounting plate 110 are all mounted on the host 200 of the medical ex vivo organ mechanical perfusion device, instead of separately arranging the centrifugal pump 120 and the peristaltic pump 130 and setting them on other devices, the volume of the medical ex vivo organ mechanical perfusion device can be reduced, the occupied space can be reduced, and the installation operation is more convenient; in addition, the distances from both the centrifugal pump 120 and the peristaltic pump 130 to the container sleeve 300 are relatively close, making the pipe connection and wiring easier and neater, and avoiding the phenomenon of messy pipe connection and wiring.

[0045] Please refer to Figure 1 and Figure 8, Further, the host 200 includes a housing 210. A third recess 211 is provided on the housing surface of the housing 210.

The power assembly 121 of the centrifugal pump 120 is disposed inside the housing 210, and the pump head 122 of the centrifugal pump 120 is located in the third recess 211. In this way, by disposing the pump head 122 of the centrifugal pump 120 in the third recess 211, the pump head 122 is prevented from being exposed outside the housing 210, which can protect the pump head 122. In addition, since the pump head 122 is located in the third recess 211, it is also convenient to disassemble and replace the pump head 122 of the centrifugal pump 120.

[0046] Please refer to Figure 1 and Figure 8 , Further, the medical ex vivo organ mechanical perfusion device further includes a container set 300. The container set 300 is detachably mounted above the housing 210.

The pipeline of the centrifugal pump 120 extends into the set housing through the pipe hole, and the pipeline of the peristaltic pump 130 extends into the set housing through the pipe hole. On the one hand, since the container set 300 is a disposable consumable and is detachably mounted above the housing 210, it is convenient to replace and perform related operations. On the other hand, both the housing 210 and the set housing are provided with pipe holes. The pipeline of the centrifugal pump 120 extends into the set housing through the pipe hole, and the pipeline of the peristaltic pump 130 extends into the set housing through the pipe hole, which avoids the exposure of the pipelines and the messy connection phenomenon, and the connection of the pipelines is relatively neat.

[0047] It should be noted that the number and opening positions of the pipe holes on the housing 210 and the set housing are not limited and can be set according to actual needs.
