Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a sample box for managing blood bags and blood samples. Background Technology

[0002] In the series of processes involving blood collection, blood refrigeration, blood supply, and transfusion, various blood bags are typically used to hold different blood components. These blood bags need to be flash-frozen or refrigerated to -30°C. Traditionally, blood circulation relies entirely on manual labor, especially in large cold storage rooms where staff must enter to store and retrieve blood bags. To automate the delivery and retrieval of blood bags in cold storage rooms, sample boxes have been developed. Blood bags are placed inside these boxes, and a robotic arm identifies and retrieves the sample box, thus achieving automated blood bag handling.

[0003] Before providing red blood cell therapy to clinical patients, medical institutions must perform cross-matching tests on the blood of both the recipient and the donor. To ensure the safety and accuracy of the plasma samples used for testing, blood banks use a tubular tube attached to the blood bag when collecting plasma from donors. This tube, containing a small amount of blood, is generally called the blood sample portion of the blood bag, or colloquially, the blood braid. Currently, the blood sample is stored in a sample box along with the blood bag. The plasma in the blood sample is primarily used for blood specimen testing. During cross-matching, the sample box needs to be opened, the entire blood bag removed, and the blood sample cut off at the tip of the next heat-sealed point. After being cut off, the blood sample is placed back into the blood bag box. Personnel contact with the blood bag causes temperature changes and artificial vibrations, increasing blood cell movement and potentially leading to excessive cell decay, thus shortening the blood's lifespan. Summary of the Invention

[0004] Therefore, it is necessary to address the technical problem that current sample boxes store blood bags and blood samples together. When performing crossmatch tests, the sample box needs to be opened, the entire blood bag needs to be taken out, the blood sample needs to be cut off, and then put back into the blood bag box. Personnel contact with the blood bag will cause changes in blood temperature and human-induced vibration, which will increase blood cell movement and lead to excessive cell decay, thus shortening the lifespan of the blood. The purpose of this invention is to provide a sample box that realizes the management of blood bags and blood samples.

[0032] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to specific embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention.

[0033] 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.

[0034] This embodiment addresses the technical problem of current sample boxes where blood bags and blood samples are stored together. When performing crossmatch tests, the entire blood bag needs to be opened, the blood sample cut out, and then placed back into the blood bag box. Personnel contact with the blood bag causes temperature changes and artificial vibrations, increasing blood cell movement and leading to excessive cell decay and shortened blood lifespan. This embodiment provides a sample box that enables scientific management of both blood bags and blood samples.

[0035] Reference Figure 1-3 The sample box for blood bag and blood sample management in this embodiment includes a box body 6, a cover body 8, a partition plate 7, and a sealing cover 9.

[0036] The top of the box 6 is open. In this embodiment, the box 6 is constructed as a rectangle to facilitate the storage of blood bags. Of course, in other embodiments, as long as the storage requirements for blood bags are met, the box 6 can also be constructed as other shapes, such as squares, ovals, or other conceivable structures. In this embodiment, the box 6 is integrally injection molded from a polymer material such as PP. Of course, in other embodiments, as long as the storage requirements for blood bags are met, the box 6 can also be made of other materials, such as metal.

[0037] A partition 7 is installed inside the box body 6, dividing the interior of the box body 6 into two areas: a blood bag chamber 1 for storing blood bags and a blood sample chamber 2 for storing blood samples. Blood bags and blood samples can be stored separately in the blood bag chamber 1 and blood sample chamber 2 through the opening at the top of the box body 6. Separating the blood bags and blood samples not only facilitates their individual management but also makes it easier to collect blood for later laboratory testing, avoiding operator contact with the blood bags and reducing the frequency of human contact, thus better protecting blood quality. Since blood samples and blood bags are usually connected as one unit, this embodiment incorporates a partition 7 to facilitate the storage and retrieval of blood bags and blood samples. Figure 4 A clearance groove is provided in the middle of the partition plate 7, which allows the blood bag and blood sample, which are connected as one piece, to be stored separately in the blood bag cavity 1 and the blood sample cavity 2. In this embodiment, the partition plate 7 and the box body 6 are integrally injection molded. Since the volume of the blood bag is larger than the volume of the blood sample, the volume of the blood bag cavity 1 should be constructed to be larger than the volume of the blood sample cavity 2.

[0038] The lid 8 is fitted to the top of the box 6 to seal the blood bag cavity 1 and the blood sample cavity 2. A recessed area 10, corresponding to the blood sample cavity 2, is provided on the lid 8, sinking into the box 6. A sampling port 3 is provided at the bottom of the recessed area 10. By providing the sampling port 3, during crossmatch testing, the blood sample is directly taken from the sampling port 3, a section is cut off for testing, and the remaining blood sample is placed back into the blood sample cavity 2. This avoids temperature changes and human-induced vibrations caused by operator contact with the blood bag, thus preventing impact on blood lifespan, reducing the number of times the blood bag is handled, and better protecting blood quality. In this embodiment, the lid 8 and the box 6 are connected by a snap-fit ​​mechanism. Of course, in other embodiments, the lid 8 and the box 6 can also be connected by a hinge and a locking mechanism. In this embodiment, mounting holes (not shown) are provided on both opposite sides of the recessed area 10 at one end of the lid 8, and grooves 11 are recessed at the top of both opposite sides of the recessed area 10 at the end away from the mounting holes. In this embodiment, to facilitate viewing the label on the blood bag stored in the blood bag cavity 1, the cover 8 is integrally injection molded from a transparent polymer material. Of course, in other embodiments, as long as the label on the blood bag can be viewed, the cover 8 can also be made of metal, and a transparent window can be provided at the corresponding position between the cover 8 and the blood bag cavity 1.

[0039] The shape of the sealing cap 9 is adapted to the shape of the sinking area 10. Pins (not shown) are provided on both sides of one end of the sealing cap 9, and the two pins are rotatably connected to the two mounting holes of the cap body 8. The sealing cap 9 can rotate around the central axis of the pins. On both sides of the end of the sealing cap 9 away from the pins, there are locking parts 12 that fit into the locking grooves 11. Rotating the sealing cap 9 until it is fully engaged in the sinking area 10, at which point the upper surface of the sealing cap 9 and the upper surface of the cap body are in the same plane, and the two locking parts 12 are engaged in the two locking grooves 11, thus sealing the sampling port 3. Disengaging the locking parts 12 from the locking grooves 11 and rotating the sealing cap 9 opens the sampling port 3, allowing blood samples to be taken from the sampling port 3, making the operation convenient.

[0040] In this embodiment, since both the box body 6 and the cover 8 are made of polymer materials, which have poor thermal conductivity, the blood inside the blood bag cools down slowly and unevenly. To enable the blood bag inside the box body 6 to cool down quickly during storage, a metal cooling plate 4 extending into the blood bag cavity 1 and the blood sample cavity 2 is provided on the inner bottom surface of the box body 6. The metal cooling plate 4 is integrally injection molded with the box body 6 by surface injection molding. Simultaneously, a slot 5 is integrally formed on one side wall of the blood bag cavity 1 of the box body 6, into which the metal cooling plate 4 can be detachably inserted. Through the metal cooling plate 4, relying on the good thermal conductivity of metal, the blood in the blood bag inside the box body 6 cools down quickly and evenly. Of course, in other embodiments, RFID electronic tags, information cards, or metal magnetic sheets can also be detachably inserted into the slot 5. RFID electronic tags facilitate the identification of sample box information; information cards can record necessary information; and metal magnetic sheets can magnetically attract the sample box, facilitating sample box storage and retrieval.

[0041] To further improve the cooling speed of the blood in the blood bag inside the box 6, in this embodiment, multiple ventilation holes 13 are provided on the box 6, the cover and the sealing cover 9. When the sample box is stored in the sample cabinet, cold air can flow directly into the sample box from the ventilation holes 13. The cold air flows over the outer surface of the blood bag and the metal cooling plate 4, which can effectively improve the cooling speed of the blood in the blood bag.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
