Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a blood matching tube holder for clinical blood transfusion. Background Technology
[0002] The blood matching process in clinical blood transfusion is to ensure that the blood received by the patient is safe and compatible, thereby avoiding possible transfusion reactions. Blood matching test tube racks are tools used in blood matching experiments to classify, fix and identify different test tubes (such as donor samples, recipient samples and crossmatch test samples). The rationality of its design directly affects the accuracy and efficiency of the experiment.
[0003] Existing blood matching tube racks often lack effective separation mechanisms, failing to clearly delineate the donor's tube area, the crossmatching test tube area, and the recipient's tube area. This increases the risk of tube confusion, potentially leading to blood type matching errors or data discrepancies, directly affecting the accuracy of the blood matching results. Utility Model Content
[0004] To overcome the drawback of test tubes being easily confused, this invention provides a blood matching test tube rack for clinical blood transfusion.
[0005] A blood transfusion tube rack for clinical blood transfusion includes a base, a fixing plate, separators, a fixing block, an adjusting screw, and a marking mechanism. The base has multiple first placement holes and two first sliding grooves on its upper side. The fixing plate has multiple second placement holes and two second sliding grooves on its upper side. The first placement holes and first sliding grooves on the base correspond one-to-one with the second placement holes and second sliding grooves on the fixing plate. The first and second placement holes are evenly distributed in three rows and multiple columns. Two separators are slidably mounted within the second sliding grooves of the fixing plate. The separators are slidably connected to the first sliding grooves. A fixing block is located at the front of each separator, and an adjusting screw is threaded onto the fixing block. Multiple fixing holes, adapted to the adjusting screw, are evenly distributed at the front of the upper side of the fixing plate. The separators can be fixed by adjusting the screw and the fixing holes. The fixing plate has a marking mechanism for marking each row of test tubes.
[0006] In a preferred embodiment of the present invention, the device further includes a storage box, a sliding cover, label cards, and label holders. The storage box is located on the left side of the fixing plate, and the label cards are placed inside the storage box. The sliding cover is slidably provided on the upper side of the storage box. Multiple label holders for storing label cards are provided on the front side of the fixing plate. The number of label holders is the same as the number of rows of the second placement holes, and they are located directly in front of each row of the second placement holes. The label holders are made of transparent material.
[0007] In a preferred embodiment of the present invention, it further includes a push block, an elastic element and a push plate. The push block is provided on the lower side of the sliding cover, and the push plate is slidably provided inside the storage box. An elastic element connects the storage box and the push plate, and a retrieval opening is provided on the front side of the storage box.
[0008] In a preferred embodiment of the present invention, it further includes limiting blocks. Two limiting blocks are provided at both the front and rear ends of the separator. The front and rear limiting blocks are located on the upper and lower sides of the fixing plate, respectively, and the length of the limiting blocks in the front-rear direction is greater than the length of the second slide groove in the front-rear direction.
[0009] In a preferred embodiment of the present invention, pulleys are also included. Pulleys are provided at both the front and rear ends of the lower side of the separator, and the bottom plate of the pulleys contacts the first sliding groove.
[0010] In a preferred embodiment of this utility model, it also includes anti-slip protrusions, with multiple anti-slip protrusions provided on both the left and right sides of the upper part of the divider.
[0011] The present invention has the following advantages: 1.

Detailed Implementation
[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.
[0019] A blood crossmatching tube rack for clinical blood transfusion, such as Figures 1-4 As shown, the device includes a base 1, a fixing plate 2, a divider 3, a fixing block 4, an adjusting screw 5, and an marking mechanism. The upper side of the base 1 has multiple first placement holes 101 and two first sliding grooves 102, located at the front and rear ends of the upper side of the base 1. The upper side of the base 1 has a fixing plate 2, which has multiple second placement holes 201 and two second sliding grooves 202, located at the front and rear ends of the upper side of the fixing plate 2. The first placement holes 101 and first sliding grooves 102 of the base 1 correspond to the second placement holes 201 and second sliding grooves of the fixing plate 2. The first placement hole 101 and the second placement hole 201 are evenly distributed in three rows and multiple columns. Two partition frames 3 are slidably provided in the second slide groove 202 of the fixing plate 2. The front and rear ends of the lower side of the partition frame 3 are slidably connected to the two first slide grooves 102 respectively. A fixing block 4 is provided on the front side of the partition frame 3. An adjusting screw 5 is threadedly connected to the fixing block 4. Multiple fixing holes 6 that are adapted to the adjusting screw 5 are evenly provided on the front part of the upper side of the fixing plate 2. The partition frame 3 can be fixed by adjusting the screw 5 and fixing holes 6. The fixing plate 2 is provided with an marking mechanism for marking each row of test tubes.
[0020] Two separators 3 divide the base 1 and the fixing plate 2 into a donor test tube area, a crossmatch test tube area, and a recipient test tube area to avoid confusion. The range of the three areas is adjustable to adapt to different usage scenarios. When adjusting the range, slide the separator 3 along the first slide groove 102 and the second slide groove 202. After reaching the appropriate position, screw the adjusting screw 5 into the fixing hole 6 to lock the separator 3 in the position corresponding to the fixing hole 6. The labeling mechanism is located in front of each row of test tubes and is used to label the purpose of each row of test tubes (such as donor number, recipient information, etc.).
[0021] like Figure 3 and Figure 4As shown, it also includes a storage box 10, a sliding cover 11, label cards 14, and label holders 15. The storage box 10 is located on the left side of the fixing plate 2, and the label cards 14 are placed inside the storage box 10. The sliding cover 11 is slidably provided on the upper side of the storage box 10. Multiple label holders 15 for storing label cards 14 are provided on the front side of the fixing plate 2. The number of label holders 15 is the same as the number of columns of the second placement holes 201, and they are located directly in front of each column of the second placement holes 201. The label holders 15 are made of transparent material. The label cards 14 are pre-stored in the storage box 10. The label cards 14 are taken out of the storage box 10, and the identification information of the corresponding test tube (such as blood donor number, blood recipient name, test item, date, etc.) is filled on the label cards 14 with a marker. Then, they are inserted into the label holders 15 of the corresponding column for identification.
[0022] like Figure 4 As shown, it also includes a push block 1101, an elastic element 12, and a push plate 13. The push block 1101 is provided on the lower side of the sliding cover 11, and the push plate 13 is slidably provided inside the storage box 10. The elastic element 12 connects the storage box 10 and the push plate 13. The storage box 10 has a retrieval opening on the front side. When the sliding cover 11 is slid backward, the push block 1101 on the lower side of the sliding cover 11 will push the push plate 13 to move backward, and the elastic element 12 will retract. At this time, a label card 14 can be placed into the storage box 10. Then, the sliding cover 11 is reset, the push block 1101 no longer presses against the push plate 13, the elastic element 12 recovers from the retracted state, and drives the push plate 13 to move forward. The push plate 13 presses the label card 14. At this time, the label card 14 can be taken out from the retrieval opening on the front side of the storage box 10 without opening the sliding cover 11.
[0023] like Figure 2 As shown, it also includes a limiting block 7. Two limiting blocks 7 are provided at both the front and rear ends of the partition frame 3. The front and rear limiting blocks 7 are located on the upper and lower sides of the fixed plate 2, respectively. The length of the limiting block 7 in the front-rear direction is greater than the length of the second slide groove 202 in the front-rear direction. The limiting block 7 can prevent the partition frame 3 from separating from the fixed plate 2 and avoid the partition frame 3 from tilting when moving.
[0024] like Figure 2 As shown, it also includes pulleys 8. Both the front and rear ends of the lower side of the partition frame 3 are provided with pulleys 8. The bottom plate of the pulley 8 contacts the first slide groove 102. Its main function is to replace sliding friction with rolling friction, which significantly reduces the resistance when the partition frame 3 moves in the first slide groove 102, so that the operator can adjust the position of the partition frame 3 more easily.
[0025] like Figure 2 As shown, it also includes anti-slip protrusions 9. Multiple anti-slip protrusions 9 are provided on the upper left and right sides of the partition frame 3. When moving the partition frame 3, you need to hold the upper part of the partition frame 3 with your hand. The anti-slip protrusions 9 increase the friction between the hand and the partition frame 3 to prevent the hand from slipping and make it easier for the operator to adjust the partition frame 3.
[0026] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model.
