Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an anti-stratification perfusion structure and perfusion device. Background Technology

[0002] In organ transplantation surgery, the transplantation of solid organs involves the process of organ removal, vascular severance, and reanastomosis. Prolonged ischemia of organs can cause damage. Therefore, it is necessary to perfuse the removed organs in a perfusion container to adjust the blood temperature and perfusion pressure. In related techniques, due to the different densities of the components of the perfusion fluid, stratification can easily occur in the perfusion container. For example, high-density components such as red blood cells accumulate at the bottom of the perfusion container, which increases blood viscosity, decreases blood oxygen saturation, reduces the viability of the removed organs, and increases the risk of transplantation surgery.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] An embodiment of the present invention provides an anti-stratification perfusion structure for preventing stratification of the perfusion fluid during perfusion of an isolated organ. (See reference...) Figures 1 to 3 The anti-stratification injection structure includes a shell 100, a mounting bracket 200, a power component 300, and a stirring component 400. The shell 100 is used to install the power component 300, and the mounting bracket 200 is used to install the stirring component 400. Specifically, the housing 100 has a sealed cavity 110 inside. The power assembly 300 includes a power element 310, which is housed inside the sealed cavity 110, isolating the power element 310 from the external environment. The mounting bracket 200 is located outside the sealed cavity 110 and is connected to one side of the housing 100. A stirring chamber 210 is formed between the mounting bracket 200 and the housing 100. Several liquid passage holes 220 are provided on the edge of the mounting bracket 200, and the stirring chamber 210 communicates with the liquid passage holes 220. The stirring assembly 400 includes a stirring element 410, which is housed in the stirring chamber 210. The stirring element 410 can rotate under the drive of the power element 310. When the stirring element 410 rotates, it can stir the injection fluid. The rotation of the stirring element 410 drives the injection fluid to continuously enter the stirring chamber 210 from the liquid passage holes 220 for stirring, and then flow out of the stirring chamber 210 from the liquid passage holes 220, breaking the stratification at the bottom of the injection fluid.

[0040] Therefore, the anti-stratification perfusion structure in this embodiment of the invention, through the power element 310 driving the stirring element 410 to rotate continuously, makes the stirring element 410 stir the perfusion fluid. Under the stirring action of the stirring element 410, the perfusion fluid is mixed evenly, reducing the degree of blood stratification. Furthermore, by reducing the stratification of the perfusion fluid, more red blood cells participate in the oxygenation cycle, greatly improving the oxygenation performance of the blood, reducing the viscosity of the perfusion fluid, reducing the amount of blood used in the perfusion process of isolated organs, and improving the perfusion effect of isolated organs.

[0041] It should be noted that, since the perfusion of ex vivo organs requires a high degree of cleanliness in terms of environment and instruments, in the embodiments of the present invention, the shell 100, the mounting bracket 200, and the stirring component 410 can all be made of chemically stable materials such as PC (polycarbonate), silicone, and rubber, and are sterilized to prevent the above components from contaminating the perfusion fluid when they come into contact with it, thus affecting the success rate of the transplantation surgery. In addition, the power element 310 is sealed in the sealed cavity 110, and the perfusion fluid only flows in the stirring cavity 210, thus avoiding contamination of the perfusion fluid by the power element 310.

[0042] The power element 310 can be a rotary drive that can actively drive the stirring component 410 to rotate, such as a motor or electric motor. The power element 310 is connected to the stirring component 410 and provides power for the rotation of the stirring component 410. Alternatively, the power element 310 can be a transmission component that transmits power to the stirring component 410. For example, the power element 310 can be a rotating body that can rotate. The power element 310 is connected to an external drive component and transmits the power of the drive component to the stirring component 410, causing the stirring component 410 to rotate.

[0043] In one embodiment, the power element 310 and the stirring element 410 are connected via the same shaft, thereby enabling power transmission from the power element 310 to the stirring element 410. Figure 4 As shown, the housing 100 includes a partition 120 and a rotating shaft 130. The rotating shaft 130 passes through the partition 120 and is connected to the partition 120. The stirring chamber 210 and the sealing chamber 110 are respectively located on both sides of the partition 120. One end of the rotating shaft 130 is housed in the sealing chamber 110 and is connected to the power element 310. The other end of the rotating shaft 130 is housed in the stirring chamber 210 and is connected to the stirring element 410. Thus, the stirring element 410 can rotate with the rotation of the power element 310. To ensure the sealing performance of the sealed cavity 110, the housing 100 also includes a sealing element 140. The sealing element 140 is sleeved on the outside of the rotating shaft 130, and the inner side of the sealing element 140 is in contact with the rotating shaft 130, while the outer side of the sealing element 140 is in contact with the partition plate 120, so as to keep the rotating shaft 130 and the partition plate 120 sealed, preventing the injection fluid from entering the sealed cavity 110 and causing injection fluid contamination.

[0044] Furthermore, the power element 310 and the stirring element 410 are respectively fixed to both ends of the rotating shaft 130. The power element 310 and the rotating shaft 130, as well as the stirring element 410 and the rotating shaft 130, can be relatively fixed by bonding or tight fitting of the shaft holes. Figure 4 As shown, the two ends of the rotating shaft 130 are respectively inserted into the power element 310 and the stirring element 410. There is a gap between the stirring element 410 and the partition plate 120 to avoid friction between the stirring element 410 and the partition plate 120 during the rotation process, which would affect the stirring efficiency of the stirring element 410.

[0045] In another embodiment, to ensure complete sealing of the sealed cavity 110, the power element 310 and the stirring element 410 transmit power in a non-contact manner. For example... Figure 2 As shown, the power assembly 300 includes a first magnet 320 connected to the power element 310 and located within the sealed cavity 110. The stirring assembly 400 includes a second magnet 420 connected to the stirring element 410 and located within the stirring chamber 210. The first magnet 320 and the second magnet 420 attract each other. Under the magnetic attraction between the first magnet 320 and the second magnet 420, the stirring element 410 can rotate with the rotation of the power element 310. Thus, the stirring element 410 can rotate without being connected to the power element 310, which can prevent the injection liquid from entering the sealed cavity 110 due to the connection between the stirring element 410 and the power element 310, thereby improving the sealing strength of the sealed cavity 110.

[0046] It should be noted that the first magnet 320 and the second magnet 420 can be opposite magnets that attract each other, or they can be a metal and a magnet that attract each other. The connection position of the first magnet 320 to the power element 310 corresponds to the connection position of the second magnet 420 to the stirring element, ensuring stable magnetic attraction between the first magnet 320 and the second magnet 420 and improving the stability of power transmission between the power element 310 and the stirring element 410. In addition, by setting the first magnet 320 and the second magnet 420, the weight of the anti-stratification pouring structure can be increased, allowing the anti-stratification pouring structure to sink to the bottom of the pouring liquid and stir the pouring liquid. This prevents the anti-stratification pouring structure from floating and being unable to stir the bottom pouring liquid, thus improving the stirring effect of the pouring liquid.

[0047] Multiple first magnets 320 and multiple second magnets 420 can be provided. Multiple first magnets 320 are distributed at different positions on the power element 310, and multiple second magnets 420 are distributed at different positions on the stirring element 410. The positions of the first magnets 320 and the second magnets 420 correspond one-to-one. In one embodiment of the present invention, both the first magnets 320 and the second magnets 420 are annular, so that the first magnets 320 and the second magnets 420 have a magnetic attraction effect throughout the entire circumference of the stirring element 410 during rotation, preventing the stirring element 410 from shifting during rotation and affecting the stability of the rotation.

[0048] The first magnet 320 can be connected to the power element 310 by adhesive bonding, and the second magnet 420 can be connected to the stirring element 410 by adhesive bonding. No other connecting components are needed, the fixing method is simple, and it does not affect the cleanliness of the injection fluid. In one embodiment, combined with... Figure 5 and Figure 6The power element 310 has a first mounting groove 311, which matches the shape of the first magnet 320. The first magnet 320 is embedded in the first mounting groove 311. The stirring element 410 has a second mounting groove 411, which matches the shape of the second magnet 420. The second magnet 420 is embedded in the second mounting groove 411. The first magnet 320 can be bonded to the first mounting groove 311, and the second magnet 420 can be bonded to the second mounting groove 411. The connection between the first magnet 320 and the power element 310, and the connection between the second magnet 420 and the stirring element 410 are more compact, which helps to reduce the volume of the anti-stratification filling structure.

[0049] Since the power element 310 and the stirring element 410 adopt a non-contact power transmission method, the first magnet 320 is sealed in the sealed cavity 110, and the first magnet 320 does not come into contact with the injection liquid. In the embodiments of the present invention, the second magnet 420 is sealed. For example, after the second magnet 420 is embedded in the second mounting groove 411, glue is poured into the second mounting groove 411 to encapsulate the second magnet 420 in the second mounting groove 411, so as to avoid the second magnet 420 from contaminating the injection liquid. In another embodiment, the stirring assembly 400 also includes a cover plate 430. At least part of the cover plate 430 is embedded in the second mounting groove 411. The second magnet 420 is clamped between the stirring element 410 and the cover plate 430. The cover plate 430 can be made of sterilized PC, silicone, rubber or other materials. The cover plate 430 blocks the second magnet 420 from contacting the injection liquid and prevents the second magnet 420 from contaminating the injection liquid.

[0050] To make the rotation of the power element 310 and the stirring element 410 more stable, in this embodiment of the invention, two opposing surfaces of the partition 120 are respectively provided with protruding posts 150. The two protruding posts 150 are rotatably connected to the power element 310 and the stirring element 410, respectively. Both the power element 310 and the stirring element 410 can rotate around the protruding posts 150. During the rotation of the stirring element 410, the partition 120 remains fixed, and the power element 310 and the stirring element 410 rotate relative to the protruding posts 150. The protruding posts 150 provide a stable rotation axis for the rotation of the power element 310 and the stirring element 410 and support the power element 310 and the stirring element 410, which can improve the stability of the rotation of the power element 310 and the stirring element 410.

[0051] The protruding post 150 should be located at the center of the partition 120 to facilitate the rotation of the power element 310 and the stirring element 410; the first magnet 320 and the second magnet 420 are both surrounding the outside of the protruding post 150, and the power element 310 and the stirring element 410 can always rotate stably around the protruding post 150 under the mutual magnetic attraction of the first magnet 320 and the second magnet 420.

[0052] In one embodiment of the present invention, there is a gap between the stirring element 410 and the partition plate 120 to prevent the friction between the stirring element 410 and the partition plate 120 from affecting the power transmission efficiency of the power element 310 to the stirring element 410; similarly, there is a gap between the power element 310 and the partition plate 120 to avoid the friction between the power element 310 and the partition plate 120 from affecting the power transmission of the power element 310 to the stirring element 410.

[0053] It should be noted that, in the embodiments of the present invention, as... Figure 3 and Figure 6 As shown, a first rotating groove 312 is provided at the center of the power element 310, and a second rotating groove 412 is provided at the center of the stirring element 410. Two protrusions 150 are respectively inserted into the first rotating groove 312 and the second rotating groove 412, realizing the connection between the power element 310, the stirring element 410 and the protrusions 150. The power element 310 and the stirring element 410 are respectively located on both sides of the partition 120. The top of the upper protrusion 150 abuts against the groove wall of the first rotating groove 312, and the bottom of the lower protrusion 150 abuts against the groove wall of the second rotating shaft 130. Under the mutual magnetic attraction of the first magnet 320 and the second magnet 420, the power element 310 is activated. The force element 310 and the stirring element 410 tend to move closer to each other. Therefore, the protrusion 150 continuously resists the stirring element 410 and the power element 310. Since the protrusion 150 has a certain length, a certain distance can always be maintained between the power element 310 and the partition 120, as well as between the stirring element and the partition 120, to ensure that the power element 310 transmits power to the stirring element 410 continuously and stably. Furthermore, after the protrusion 150 is inserted into the first rotating shaft 130 and the second rotating groove 412, the partition 120 can be connected to the power element 310 and the stirring element 410 without the need for other mating structures, resulting in high connection convenience.

[0054] In addition, the second magnet 420 is connected to the side of the stirring member 410 away from the partition 120, and the cover plate 430 is located at the end away from the protrusion 150. The second magnet 420 is always subjected to the upward magnetic attraction of the first magnet 320, which causes the stirring member 410 to have an upward moving tendency. Compared with the second magnet 420 being connected to the side of the stirring member 410 close to the partition 120, the cover plate 430 is not affected by the magnetic attraction, preventing the cover plate 430 from loosening due to the magnetic attraction between the first magnet 320 and the second magnet 420, so that the cover plate 430 can always maintain the sealing effect on the second magnet 420.

[0055] Furthermore, the end of the protrusion 150 is arc-shaped to reduce the contact area between the protrusion 150 and the wall of the first rotating groove 312 or the second rotating groove 412, thereby reducing the friction between the protrusion 150 and the power element 310 and the agitator 410; alternatively, the top of the protrusion 150 can be flattened, retaining only a portion of the arc surface, to further reduce the contact area between the protrusion 150 and the power element 310 and the agitator 410. The protrusion 150 and the partition 120 can be integrally connected, such as by injection molding or stamping, to isolate the sealing cavity 110 from the agitator 210.

[0056] In an embodiment of the present invention, the housing 100 further includes a cover 160, which is interlocked with the partition 120 to form a sealed cavity 110. The power element 310 is rotatably connected to the cover 160. During assembly of the anti-delamination filling structure, the first magnet 320 is first fixed in the first mounting groove 311 of the power element 310. Then, the power element 310 is connected to the cover 160 and the protrusion 150. After the partition 120 is encapsulated with the cover 160, the power element 310 is sealed within the sealed cavity 110. Then, the second magnet 420 and the cover 160 are installed in the second mounting groove 411 and fixed. After the stirring element 410 is connected to the protrusion 150 and the mounting bracket 200, the mounting bracket 200 is connected and fixed to the partition 120, completing the assembly.

[0057] An annular protrusion 161 protrudes from the side of the cover 160 facing the sealing cavity 110, and an annular groove 313 is provided on the side of the power element 310 facing away from the protrusion 150. The annular protrusion 161 is inserted into the annular groove 313. When the power element 310 rotates, the annular protrusion 161 rotates relative to the groove wall of the annular groove 313, and the annular protrusion 161 guides the rotation of the power element 310. Furthermore, both sides of the power element 310 are supported by the annular protrusion 161 and the protrusion 150. The annular protrusion 161 and the protrusion 150 are aligned with the axis of the rotating shaft 130 of the power element 310, so that the two sides of the power element 310 remain balanced when it rotates, which can improve the smoothness of the rotation of the power element 310 and the power transmission efficiency.

[0058] It should be noted that there is also a gap between the agitator 410 and the support. That is, there is a gap between the agitator 410 and the end face of the support facing away from the housing 100. During the filling process, due to the gap between the two, the agitator 410 is lifted, allowing the filling liquid to flow to the bottom of the agitator 410, avoiding contact between the agitator 410 and the ground of the container and mutual friction, thus ensuring the agitation strength of the agitator 410 on the filling liquid.

[0059] The agitator 410 should have multiple agitator blades 414 to enable the agitator 410 to have a high agitation force on the injection fluid, such as Figure 3As shown, the stirring component 410 includes a stirring shaft 413 and multiple stirring blades 414. The multiple stirring blades 414 are connected to the outer periphery of the stirring shaft 413. The stirring shaft 413 is connected to the protrusion 150. When the stirring shaft 413 rotates, the stirring blades 414 stir the injection liquid to achieve stirring of the injection liquid.

[0060] The mounting bracket 200 includes multiple supports 230, which are spaced apart and connected to the side of the partition 120 facing away from the cover 160. The multiple supports 230 are arranged circumferentially along the partition 120, and liquid passage holes 220 are formed between adjacent supports 230. The liquid passage holes 220 are distributed on the outer periphery of the housing 100, and the injection liquid can enter the stirring chamber 210 through different liquid passage holes 220 to improve the uniformity of the stirring of the injection liquid by the stirring component 410. In one embodiment, the mounting bracket 200 further includes a base plate 240, and multiple supports 230 are connected to the base plate 240. The base plate 240 is connected to the end of the supports 230 facing away from the partition 120. The base plate 240 and the supports 230 can be integrally connected, so that the base plate 240 and the supports 230 can be connected to the partition 120 as an integral structure, which improves the convenience of assembling the injection structure. In addition, the base plate 240 can increase the weight of the injection structure, so that the injection structure can stir the injection liquid at the bottom. Furthermore, the large contact area between the base plate 240 and the bottom surface of the container can reduce the shaking of the injection structure when the stirring component 410 rotates, improve the stability of the injection structure during operation, and reduce noise.

[0061] The rotation of the power element 310 can be achieved by connecting an external drive component via a connecting wire. For example, the housing 100 also includes a connecting channel that communicates with the sealed cavity 110. The inner cavity of the connecting channel allows the wire to pass through. One end of the wire is connected to the power element 310, and the other end is connected to the external drive component. The rotation of the power element 310 is achieved while the sealed cavity 110 remains sealed. It should be noted that the connecting channel should have a certain length to ensure that, during the filling process, the end of the connecting channel furthest from the housing 100 is above the surface of the filling fluid.

[0062] In one embodiment of the present invention, the power element 310 rotates via fluid drive. Specifically, the housing 100 includes an input pipe 170 and an output pipe 180, both of which are connected to the sealed cavity 110. The input pipe 170 is used to supply fluid into the sealed cavity 110, and the output pipe 180 is used to allow fluid to flow out of the sealed cavity 110. The power element 310 has several rotating blades 314. When fluid flows into the sealed cavity 110 through the input pipe 170, due to the fluid's certain flow velocity and pressure, the fluid drives the rotating blades 314 to oscillate, thereby achieving the rotation of the power element 310. The power element 310 can drive the stirring element 410 to rotate via magnetic attraction. As fluid continuously enters the sealed cavity 110, the power element 310 continuously drives the stirring element 410 to stir the injection fluid.

[0063] By adopting a fluid-driven method, the rotation of the power element 310 is achieved on the one hand, and on the other hand, the rotation of the power element 310 is not affected by the magnetic field of the magnet, which facilitates the non-contact power transmission between the power element 310 and the stirring component 410 through magnetic attraction.

[0064] It is conceivable that flow valves, pressure reducing valves, or other valve bodies are installed on the input pipe 170 and / or output pipe 180 to change the flow rate of the fluid entering the sealed cavity 110, thereby regulating the rotation speed of the stirring element 410. Alternatively, the fluid can be gas or liquid; the flow of the fluid actuates the rotating blades 314, thus rotating the power element 310.

[0065] The input pipe 170 and the output pipe 180 can be located on opposite sides of the housing 100 to prevent turbulence in the sealed cavity 110. Alternatively, flexible hoses 190 can be connected to the ends of the input pipe 170 and the output pipe 180 to increase the overall length of the pipes and raise their height above the injection fluid level. The power element 310 includes a power shaft 315 and multiple rotating blades 314. The multiple rotating blades 314 are connected to the outer periphery of the power shaft 315. The multiple rotating blades 314 are simultaneously agitated by the fluid, increasing the tangential force on the power element 310 and thus increasing its rotational speed.

[0066] like Figure 5As shown, the present invention also provides an infusion device, which includes the above-mentioned anti-stratification infusion structure and an infusion container 500. The anti-stratification infusion structure is placed inside the infusion container 500. The infusion container 500 is used for placing excised organs and for pouring in the infusion fluid. The anti-stratification infusion structure is located at the bottom of the infusion container 500. The hose connected to the inlet pipe 170 and the outlet pipe 180 extends to the top of the infusion container 500. When the infusion fluid is poured, the agitator 410 agitates the infusion fluid to prevent the infusion fluid from stratifying inside the infusion container 500.

[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
