[0002] After clinical blood transfusion, the recycling of blood bags is not only an important part of hospital medical administration and nosocomial infection management, but also an important part of clinical safe blood transfusion. When recycling blood bags, after pulling out the infusion set from the blood bag, due to the high viscosity of the blood, there is residual blood in the blood bag. Medical staff need to fold the blood bag from the blood transfusion socket with a puncture hole, and then seal the blood bag with a yellow identification bag, paste it with glue. After sealing, the yellow identification bag containing the blood bag is placed in the refrigerator for short-term storage for verification. However, there is still a small amount of residual blood flowing out from the puncture hole of the blood bag folded and placed in the refrigerator. It is inevitable that there will be contamination when reopening the yellow identification bag for verification, which has potential safety hazards. Summary of the Invention

[0055] See Figures 1 to 7 , this embodiment provides a blood transfusion bag recycling device, including a mounting structure 10, a holder 20, a storage box 30 and a part moving mechanism 50.

[0056] The holder 20 is detachably arranged on the mounting structure 10. The storage box 30 is arranged on the mounting structure 10, and a plurality of engaging members 40 are stored in the storage box 30. The part moving mechanism 50 can move the engaging members 40 from the storage box 30 to the holder 20. Two adjacent engaging members 40 can be connected to each other, and the two connected engaging members 40 can fix the blood transfusion socket of the blood transfusion bag. Specifically, when the blood transfusion socket of the blood transfusion bag is upward, the two engaging members 40 fix the blood transfusion socket.

[0057] In this embodiment, after the blood transfusion bag is used up and the infusion set is removed, the blood transfusion socket of the blood transfusion bag is placed upward to prevent residual blood from flowing out. The transfer mechanism 50 moves a clamping member 40 onto the holder 20. At this time, the blood transfusion socket of the blood transfusion bag is placed at the clamping member 40. Then, the moving mechanism moves another clamping member 40 to connect with the previous clamping member 40 and together fix the blood transfusion socket of the blood transfusion bag, so as to keep the blood transfusion socket of the blood transfusion bag always upward and prevent residual blood from flowing out. Different blood transfusion bags can be fixed on the clamping member 40 in the above manner in sequence, and the clamping member 40 can be held on the holder 20. Finally, the holder 20 can be removed from the mounting structure 10, and the holder 20 together with the blood transfusion bags thereon can be placed in a refrigerator for storage for subsequent verification. In addition to ensuring that the residual blood in the blood transfusion bag does not flow out, since multiple blood transfusion bags are fixed by multiple clamping members 40, the blood transfusion bags are arranged neatly and labeled. If verification is needed subsequently, they can be found intuitively and conveniently. Compared with the traditional method of loading blood transfusion bags into a yellow identification bag and then placing them in a refrigerator, the blood transfusion bags arranged neatly on the holder 20 can also reduce space occupancy. Finally, when the storage time ends and the blood transfusion bags need to be transferred to professional medical waste disposal personnel, the blood transfusion bags arranged in batches on the holder 20 according to the blood transfusion bag recycling time can also be processed in batches, saving time. In the past, one yellow identification bag was used to load one blood transfusion bag to prevent mixing of different blood transfusion bags. The blood transfusion bags handed over to medical waste disposal personnel in the same batch can be loaded into one yellow identification bag subsequently, saving the use quantity of yellow identification bags.

[0058] In one embodiment, the holder 20 includes a fixing plate 21, a holding rod 22, and a holding plate 23.

[0059] The fixing plate 21 is detachably mounted on the mounting structure 10. Two holding rods 22 are arranged in parallel, and one end of each is fixedly connected to the fixing plate 21. The holding plate 23 is slidably arranged on the holding rods 22 through openings. The transfer mechanism 50 can push the clamping member 40 to move on the holding rods 22, and the holding plate 23 can be held stationary on the holding rods 22. The holding plate 23 can abut against the clamping member 40 to form a support. Specifically, the transfer mechanism 50 pushes the clamping member 40 from the end of the holding rod 22 away from the fixing plate 21 towards the fixing plate 21, and the holding plate 23 is located between the clamping member 40 and the fixing plate 21.

[0060] In this embodiment, the transfer mechanism 50 moves the engaging members 40 in the storage box 30 to the holding rod 22 one by one. The holding plate 23 is fixed in place by being clamped to the holding rod 22 or other means. After the previous engaging member 40 abuts against the holding plate 23, the next engaging member 40 continues to be moved by the transfer mechanism 50 and abuts against the previous engaging member 40, so that the two engaging members 40 are clamped to each other, thereby realizing the common fixation of the blood transfusion sockets of the two blood transfusion bags by the two engaging members 40. The holding plate 23 provides support for the engaging member 40, so that the next engaging member 40 can be smoothly clamped to the previous engaging member 40.

[0061] In one embodiment, the mounting structure 10 includes a mounting tube 11, a limit pin 12, a tail block 13, and a spring 14.

[0062] The mounting tube 11 is horizontally arranged, one end of which is connected to the storage box 30, and a plurality of mounting holes 111 are formed in the upper side thereof along the length direction. A plurality of limit pins 12 are provided, and the limit pins 12 are slidably arranged in the corresponding mounting holes 111. A plurality of limit blocks 24 are provided, and the tail block 13 is connected to the end of the corresponding limit pin 12. The spring 14 is sleeved on the limit pin 12, one end of the spring 14 is connected to the outer wall of the mounting tube 11, and the other end of the spring 14 is connected to the tail block 13.

[0063] A limit groove 112 is formed in the lower side of the mounting tube 11 along the length direction. The upper end of the holding plate 23 is connected with a first connecting member. The first connecting member passes upward through the limit groove 112 and then is connected with a limit block 24. The limit block 24 is slidably arranged in the mounting tube 11. The upper end of the limit block 24 can contact the bottom of different limit pins 12. The middle part of the upper end of the limit block 24 is higher than the surrounding. A clamping groove 241 is formed in the middle part of the upper end of the limit block 24. The limit pin 12 can abut in the clamping groove 241. The upper end of the fixing plate 21 is connected with a second connecting member. The second connecting member passes through the limit groove 112 and then is connected with a limit plate 25. The limit plate 25 is slidably inserted into the mounting tube 11. The inner wall of the end of the mounting tube 11 away from the storage box 30 is provided with threads and is threadedly connected with a stop block 15. In addition, a sliding bar can be arranged in the mounting tube 11, and sliding grooves are correspondingly formed in the limit block 24 and the limit plate 25 to prevent the limit block 24 and the limit plate 25 from rotating in the mounting tube 11.

[0064] In this embodiment, as Figure 1, keep the holding plate 23 together with the limiting block 24 thereon starting from the right end of the mounting pipe 11 and slide leftward along the limiting groove 112. The limiting block 24 passes by the lower ends of a plurality of limiting pins 12, while the fixing plate 21 together with the limiting plate 25 thereon slides into the mounting pipe 11 from the right end of the mounting pipe 11. The stop block 15 can be threadedly connected to the inner wall of the mounting pipe 11 and then removed after placing the fixing plate 21. The engaging member 40 slides rightward from the left end of the holding rod 22 and abuts against the holding plate 23. The holding plate 23 can provide a leftward supporting force to the engaging member 40 under the action of the spring 14. As the moving member mechanism 50 on the left side pushes another engaging member 40 rightward along the holding rod 22, the two engaging members 40 are snap-connected into one body.

[0065] In one embodiment, the storage bin 30 has an upper opening 31 and a lower opening 32. The engaging member 40 slides into the storage bin 30 from the upper opening 31 and slides out from the lower opening 32. A connecting plate is further connected to the lower opening 32, and a receiving plate 33 is connected to the lower end of the connecting plate. A plurality of engaging members 40 are stacked on the receiving plate 33, and the moving member mechanism 50 can push the engaging members 40 on the receiving plate 33 onto the holding rod 22. Specifically, sliding strips are provided on both sides of the inner wall of the storage bin 30, and corresponding sliding grooves are provided on the engaging member 40, so that the engaging member 40 can slide up and down in the storage bin 30.

[0066] In one embodiment, the moving member mechanism 50 includes a handle 51 and a pushing block 52.

[0067] The handle 51 is slidably arranged on the storage bin 30. The pushing block 52 is connected to the handle 51 and can push the engaging members 40 on the receiving plate 33.

[0068] In this embodiment, hold the handle 51 and the storage bin 30. When the handle 51 approaches the storage bin 30, the pushing block 52 pushes the engaging members 40 on the receiving plate 33 towards the holding rod 22 until the engaging members 40 are in sliding fit with the holding rod 22.

[0069] In one embodiment, engaging grooves 41 that are symmetric to each other are formed on both sides of the engaging member 40. The engaging grooves 41 are arranged longitudinally and have open lower ends. The inner space of the engaging groove 41 is a semi-cylindrical body. A semi-circular ring 42 is connected to the inside of the open end of the engaging groove 41. A semi-circular sleeve 43 arranged longitudinally is connected to the inner circle of the semi-circular ring 42. Guide posts 44 are provided on both sides of the engaging member 40. Guide holes 45 with the same center line are formed in the guide posts 44. The guide holes 45 can be slidably engaged with the holding rod 22. When the two engaging members 40 are clamped, the two engaging grooves 41 together form a cylindrical space, the two semi-circular rings 42 enclose a circular ring, and the two semi-circular sleeves 43 enclose a sleeve that is smaller at the upper end and larger at the lower end. Specifically, a groove along the length direction of the holding rod 22 is further provided at the lower end of the engaging member 40. Correspondingly, a slide rail (or strip-shaped protrusion) that is slidably engaged with the groove is provided on the receiving plate 33. The cross-sectional shape of the slide rail is preferably triangular, so that when the engaging member 40 falls from the storage box 30 onto the receiving plate 33, the groove is guided by the slide rail, so that the guide hole 45 corresponds to the holding rod 22.

[0070] In this embodiment, a blood transfusion hose is usually externally connected to the blood transfusion bag. The blood transfusion hose is connected to a shorter transition tube. A plug for blocking the outflow of blood is provided in the transition tube. The needle of the infusion set takes blood after passing through the plug in the transition tube. In this device, the transition tube is placed in the engaging grooves 41 of the two engaging members 40. Since the size of the transition tube is larger than that of the blood transfusion hose, the lower end of the transition tube is limited by the semi-circular sleeves 43 of the two engaging members 40. The upper ends of the two semi-circular sleeves 43 are retracted compared to their lower ends, so as to maintain a seal with the blood transfusion hose. Once residual blood flows out of the transition tube, the residual blood can flow to the semi-circular ring 42 and cannot flow out from the upper end of the semi-circular sleeve 43. The engaging member 40 can be made of rubber material to obtain better sealing performance.

[0071] In one embodiment, the guide post 44 has a large-diameter end and a small-diameter end. The guide hole 45 has a large-diameter end and a small-diameter end. A blocking ring 46 that contracts inward is provided in the guide hole 45. A mating ring 47 is provided on the outer wall of the guide post 44. The small-diameter end of the guide post 44 can be inserted into the guide hole 45 of the adjacent guide post 44 on the same side. When the guide post 44 is inserted into the guide hole 45, the mating ring 47 can contact the blocking ring 46 and deform and move to the other side of the blocking ring 46.

[0072] In this embodiment, under the push of the push block 52, the engaging member 40 is pushed from the receiving plate 33 onto the holding rod 22. The engaging member 40 contacts the engaging member 40 that is already on the holding rod 22. The guiding post 44 on the previous engaging member 40 is inserted into the guiding hole 45 of the subsequent engaging member 40. After the fitting ring 47 is deformed, it moves to the other side of the blocking ring 46 to realize the clamping connection of the two engaging members 40. Since the large-diameter end of the guiding hole 45 is closer to the holding plate 23 than its small-diameter end, that is to say, the large-diameter end of the guiding hole 45 contacts the end of the holding rod 22 first, so that the engaging member 40 can easily slide onto the holding rod 22.

[0073] In one embodiment, it further includes two locking members 60 and two driving members 70.

[0074] The two locking members 60 are located on both sides of the mounting tube 11 and can slide close to or away from the mounting tube 11. The lower ends thereof have locking claws 61 that can fit with the small-diameter ends of the guiding posts 44. The two driving members 70 are respectively slidably arranged on the outer walls on both sides of the storage bin 30, one end is connected to the handle 51, and the other end is connected to a driving frame 71.

[0075] Each of the locking members 60 is located in the driving frame 71 on the same side. When the driving frame 71 moves along the length direction of the holding rod 22 and approaches the fixing plate 21, the driving frame 71 drives the locking member 60 to approach the mounting tube 11, and the locking claw 61 abuts against the end of the corresponding guiding post 44. When the driving frame 71 moves along the length direction of the holding rod 22 and moves away from the fixing plate 21, the locking claw 61 moves away from the corresponding guiding post 44.

[0076] Specifically, the driving frame 71 has two mutually parallel first side rods 711 and two mutually parallel second side rods 712. The ends of the first side rods 711 and the ends of the second side rods 712 are fixedly connected. The two first side rods 711 are inclined with respect to the mounting tube 11, while the two second side rods 712 are parallel with respect to the mounting tube 11. One end of the first side rod 711 away from the second side rod 712 gradually moves away from the mounting tube 11. This enables the locking member 60 to move in the driving frame 71 when the driving member 70 moves along the length direction of the holding rod 22. The first side rod 711 will play a guiding role, thereby driving the locking member 60 to approach or move away from the mounting tube 11, and further enabling the locking claw 61 below the locking rod to approach or move away from the guiding post 44. When the locking claw 61 fits with the small-diameter end of the corresponding guiding post 44, it also abuts against the end of the large-diameter end of the guiding post 44 at the same time, so as to restrict one guiding member, so that when the push block 52 pushes the next engaging member 40 onto the holding rod 22 and connects it with the previous engaging member 40, the previous engaging member 40 remains in place.
