Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a blood bag container for a centrifuge. Background Technology

[0002] Component transfusion has been widely used in clinical practice due to its advantages such as saving blood resources, high specificity, good efficacy, few side effects, and ease of storage and transportation. Currently, component transfusion mainly includes red blood cell transfusion, granulocyte transfusion, platelet transfusion, and plasma and plasma protein product transfusion. With the rapid development of component transfusion, higher standards are being demanded for component blood. Currently, commercially available equipment for automatically separating different blood components is available, and methods for separating red blood cells and plasma using automated blood component separators have also emerged. However, the blood component separation process has the following drawbacks:

[0003] When separating blood components, multiple bags need to be stacked together and placed into the adapter. After centrifugation, the bags and stopper rod joints tilt and become entangled with each other, making it difficult to separate multiple bags during subsequent fully automatic operation. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a blood bag compartment for centrifuges that prevents the bags and stopper rod joints from tipping over and tangling with each other, and facilitates the separation of multiple bags.

[0005] One of the objectives of this invention is achieved through the following technical solution:

[0006] A blood bag compartment for a centrifuge includes a compartment body, an adapter mounted on the compartment body, and a top cover. The top cover is mounted on the upper end of the compartment body and includes a positioning pin. The blood bag compartment for the centrifuge also includes a limiting structure, which includes a body, a mounting pin, and an elastic element. The mounting pin is fixed to the top cover, and the body is rotatably mounted on the mounting pin. The body has a limiting hole, a positioning groove, and a limiting post. The two ends of the elastic element respectively abut against the body and the mounting pin, allowing the body to move vertically relative to the mounting pin. When the body moves upward relative to the mounting pin, the positioning pin disengages from the limiting hole, allowing the body to rotate relative to the mounting pin. The positioning groove receives the stopper rod of the bag, and the limiting post extends into the through hole of the bag to position the connection between the stopper rod and the bag body. When the body moves downward relative to the mounting pin, the positioning pin is located in the limiting hole, circumferentially positioning the body and the top cover.

[0007] Furthermore, the axis of the mounting pin is perpendicular to the extension direction of the limiting post.

[0008] Furthermore, there are multiple limiting posts, which are located at both ends of the main body.

[0009] Furthermore, there are multiple positioning slots, which are located at both ends of the main body.

[0010] Furthermore, there are multiple positioning pins, the upper cover is provided with a through hole, the mounting pin is fixed to the through hole, and the multiple positioning pins surround the through hole.

[0011] Furthermore, the adapter is provided with a first mounting slot and a second mounting slot. The first mounting slot is used to install multiple bags, and the second mounting slot is used to install one bag. The top cover is provided with multiple clearance slots and a separation slot. The first mounting slot corresponds to the multiple clearance slots, and the separation slot is located between the multiple clearance slots corresponding to the first mounting slot.

[0012] Furthermore, the first mounting groove corresponds to the two clearance grooves, the upper cover includes a cover plate and a hook, a plurality of clearance grooves are disposed on the cover plate, and the hook is located between the two clearance grooves.

[0013] Furthermore, the upper cover includes a cover plate and a fastener. The cover plate has a fastening groove, and the fastener is located at the edge of the fastening groove and partially above the fastening groove. The fastening groove fastens the pipeline, and the fastener abuts against the pipeline.

[0014] Furthermore, the upper cover is provided with a pressing hole, the compartment body includes an end, the end is provided with a slot, and the pressing hole corresponds to the position of the slot.

[0015] Furthermore, the upper cover is provided with a slot located on the side wall of the upper cover.

[0016] Compared to existing technologies, the centrifuge blood bag compartment of this invention has a mounting pin fixed to the top cover, and the main body is rotatably mounted on the mounting pin. The main body is provided with a limiting hole, a positioning groove, and a limiting post. The two ends of the elastic element respectively abut against the main body and the mounting pin, allowing the main body to move vertically relative to the mounting pin. When the main body moves upward relative to the mounting pin, the positioning pin disengages from the limiting hole, and the main body can rotate relative to the mounting pin. The positioning groove accommodates the bag's plug rod, and the limiting post extends into the bag's through hole to position the joint between the plug rod and the bag body. When the main body moves downward relative to the mounting pin, the positioning pin is located in the limiting hole, positioning the main body circumferentially with the top cover. Through the above design, the bag's plug rod is snapped into the positioning groove, and the limiting post extends into the bag's through hole to position the joint between the plug rod and the bag body. This prevents the bag and plug rod joint from tipping over and tangling during centrifugation, facilitating the separation of multiple bags. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] like Figures 1 to 12 As shown, the blood bag compartment for centrifuges of the present invention includes a compartment body 10, an adapter 20, a top cover 30, and a limiting structure 40.

[0034] The housing 10 includes a main body 11, two end portions 12, and a plurality of guide posts 13. The two end portions 12 extend from both ends of the main body 11. The main body 11 has a receiving portion 110 for mounting the adapter 20. Each end portion 12 has a slot 120 for pressing. The plurality of guide posts 13 extend from the upper end of the main body 11. Specifically, there are four guide posts 13, located on both sides of the main body 11.

[0035] The adapter 20 includes a housing 21, a partition 22, a handle 25, and a boss 26. The outer wall of the housing 21 is provided with a ventilation groove 210, which extends from the top to the bottom of the outer wall to prevent difficulty in operation due to air pressure when inserting or removing the compartment 10.

[0036] A partition 22 is fixed inside the housing 21, dividing the housing 21 into a first mounting groove 23 and a second mounting groove 24. Specifically, the volume of the first mounting groove 23 is larger than that of the second mounting groove 24. The first mounting groove 23 is used to install transfer bags and blood bags. The second mounting groove 24 is used to install preservation fluid bags. The bottoms of the first mounting groove 23 and the second mounting groove 24 have smooth transition rounded corners to prevent the bags from bursting during centrifugation. Two handles 25 extend from the top of the housing 21, located at the middle of each side of the housing 21. Each handle 25 has a gripping hole 250, allowing a robotic arm to reach into the gripping hole 250 to grip the adapter 20, thus achieving full automation of blood bag centrifugation. Four bosses 26 extend from the top of the housing 21 and are hollow. When the adapter 20 is installed in the chamber 10, the guide post 13 extends into the bosses 26 to position the adapter 20 in relation to the chamber 10.

[0037] The top cover 30 includes a cover plate 31, a winding end 32, a pressing end 33, a fastening element 34, a positioning pin 35, and a hook 36. The cover plate 31 has three clearance grooves 310, two of which correspond to and communicate with the first mounting groove 23. The third clearance groove 310 corresponds to and communicates with the second mounting groove 24. The winding end 32 extends from one end of the cover plate 31 and has a groove 320 for winding the tubing. The pressing end 33 extends from the other end of the cover plate 31 and has a fastening groove 330 for fastening the tubing of the bag 200. The pressing end 33 also has a pressing hole 331 and a counterweight hole 332. The pressing hole 331 corresponds to the slot 120 and is used for heat pressing. The counterweight hole 332 is used to install a counterweight block to adjust the center of gravity of the blood bag chamber for the centrifuge. The fastening element 34 extends from the pressing end 33 and is located at the edge of the fastening groove 330. The edge of the fastening element 34 is located above the fastening groove 330. The fastening element 34 abuts against the pipeline located in the fastening groove 330 to prevent the pipeline from dislodging from the fastening groove 330.

[0038] The cover plate 31 has a through hole 311, a slot 312, and a separation groove 313. The through hole 311 is used to fix the mounting pin 42. The slot 312 is located on the side wall of the cover plate 31 and is used for the insertion of the robotic arm. The separation groove 313 is located between two clearance grooves 310 and is used to insert the separation rod. The diameter of the separation rod is smaller than the cross-sectional width of the long groove to ensure smooth passage. After centrifugation, the outer walls of the blood bag and transfer bag will stick together. When the top cover 30 and the adapter 20 separate, the separation rod remains in the same position, and the top cover 30 moves vertically upward together with the blood bag and transfer bag. The blood bag and transfer bag will gradually separate as they pass the separation rod, facilitating subsequent blood bag squeezing operations. The positioning pin 35 extends from the cover plate 31 and is perpendicular to the cover plate 31. There are multiple positioning pins 35, which surround the through hole 311. The positioning pins 35 prevent the limiting structure 40 from tilting during centrifugation. Hook 36 extends from cover plate 31 and is located between two clearance slots 310 for suspending transfer bags.

[0039] The limiting structure 40 includes a body 41, a mounting pin 42, and an elastic element 43. The body 41 has positioning grooves 410 and limiting posts 411 at both ends. The positioning grooves 410 are used to secure the stopper 201 of the bag 200, and the limiting posts 411 are used to extend into the through hole 202 at the end of the bag 200. The body 41 also has limiting holes 413.

[0040] The limiting hole 413 of the main body 41 is placed on the positioning pin 35. The elastic element 43 is a spring, which is placed inside the main body 41. The mounting pin 42 extends into the main body 41 and the elastic element 43. The end of the mounting pin 42 is fixed to the through hole 311 of the upper cover 30. At this time, the main body 41 can move up and down along the mounting pin 42. The two ends of the elastic element 43 abut against the mounting pin 42 and the main body 41, respectively.

[0041] When using the blood bag compartment of the centrifuge, the limiting structure 40 is located in the width direction of the upper cover 30 to prevent the limiting structure 40 from obstructing the clearance groove 310. Blood bags, transfer bags, and preservation fluid bags are placed into the first mounting groove 23 and the second mounting groove 24 of the adapter 20 through the clearance groove 310. The first mounting groove 23 is used to install the transfer bag and the blood bag. The second mounting groove 24 is used to install the preservation fluid bag. An upward external force is applied to the body 41, compressing the elastic element 43, causing the body 41 to move upward, and the positioning pin 35 disengages from the limiting hole 413. The body 41 rotates relative to the mounting pin 42. After rotating 90 degrees, the external force is removed, and the body 41 moves downward and resets under the elastic force of the elastic element 43. The limiting hole 413 extends into the positioning pin 35, positioning the body 41. At this time, the stopper 201 is placed in the positioning groove 410, and the through hole 202 of the bag 200 extends into the limiting post 411. When the centrifuge is centrifuged, it can prevent the bag 200 and the joint of the stopper 201 from tilting and intertwining with each other, which facilitates the separation of multiple bags.

[0042] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
