Technical Field
[0001] This utility model relates to the field of blood analyzer technology, specifically to a sample tray for a blood analyzer. Background Technology
[0002] A blood cell analyzer is a routine clinical laboratory instrument that automatically analyzes the heterogeneity of blood cells in a given volume of whole blood. It is also known as an automated blood cell counter or blood analyzer. During operation, a blood analyzer performs a series of steps, including sampling, aspiration, dilution, mixing, transfer, detection, and cleaning of the blood sample. The analytical results are obtained through processing by an embedded motherboard. The sample tray is a device for storing samples and reagents.
[0003] The sample tray (also called a sample holder or sample rack) used in a blood analyzer is a key component for holding and transporting blood samples (such as EDTA-anticoagulated whole blood, serum, or plasma), and is typically used in conjunction with an automated blood analysis system. Types of sample trays include: circular rotary trays, commonly found in small or semi-automated analyzers, where sample tubes are placed directly on the rotating tray and processed sequentially by the instrument; and strip-track trays, used in fully automated analyzers, where sample tubes are inserted into a strip rack and fed sequentially via a conveyor belt. Multi-module integrated trays: High-throughput instruments may employ a multi-tray linkage design to support continuous sample loading.
[0004] The existing sample trays have very small spacing, which makes it difficult for doctors to place blood samples into the trays after drawing them in order to accommodate the subsequent analyzer tests. The blood sample tubes are very close together and need to be inserted one by one. In addition, after the blood samples in the trays are tested, they need to be removed and discarded one by one. The small spacing between the tubes makes it very inconvenient to remove the tested samples. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a sample tray for a blood analyzer, which can effectively solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a sample tray for a blood analyzer, including a sample tray body. A rotating rod is rotatably connected to the top of one end of the inner wall of the sample tray body. One end of the rotating rod passes through the outer wall of the sample tray body and is fixed with a knob. A winding roller is fixed to the middle of the outer wall of the rotating rod. A connecting rope is wound around the outer wall of the winding roller. A second hinge seat is fixed to the inner wall of the sample tray body away from the winding roller. First connecting rods are hinged to both ends of the inner wall of the second hinge seat. Cross rods are hinged to both ends of the first connecting rods. Second connecting rods are hinged to both ends of the cross rods away from the first connecting rods. A first hinge seat is hinged to one end of the two second connecting rods at opposite ends. One end of the first hinge seat is fixed to one end of the connecting rope. Elastic ropes are fixed to the opposite ends of the two first connecting rods. The other ends of the two elastic ropes are fixed to the inner wall of the sample tray body.
[0007] Furthermore, multiple crossbars are provided, with the ends of two adjacent crossbars hinged to each other, and two first connecting rods, two second connecting rods, and multiple crossbars are located in a group.
[0008] Furthermore, the multiple sets of crossbars are arranged horizontally at equal intervals, and the multiple crossbars in two adjacent sets are movably connected by a first connecting block, which is rotatably connected to the bottom of two crossbars on both sides.
[0009] Furthermore, a ratchet is fixed to the outer wall of the rotating rod near the knob, and a second connecting block and a connecting shaft are fixed to the outer wall of the sample disc near the knob. A toggle lever is rotatably connected to the outer wall of the connecting shaft.
[0010] Furthermore, the top of the toggle lever is located above the top of the knob, and a limit block is fixed to the bottom of the toggle lever near the ratchet. The limit block is used in conjunction with the ratchet. A spring is fixed to the top of the toggle lever, and the other end of the spring is fixed to one side of the second connecting block.
[0011] Furthermore, a sponge pad is fixed to the bottom of the inner wall of the sample disc, and the top of the sample disc and the top of the crossbar are located on the same horizontal plane.
[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This application uses a knob to rotate a rotating rod, which winds the connecting rope around the outside of the roller and pulls the first hinge seat to one end. At this time, the elastic rope stretches, and the hole of the cross rod becomes larger. The larger hole makes it easier to place the test tube. Then, by pressing the lever, the engagement between the limiting block and the ratchet is released. At this time, the elastic rope contracts, making the hole of the cross rod smaller. This allows for quick adjustment of the hole size for placing the test tube, achieving the effect of convenient placement and processing of blood sample test tubes.
[0013] 2. This application uses crossbars to clamp blood sample tubes and place the sample tray into the analyzer for testing. After clamping, the spacing between the tubes meets the standard sample tray spacing requirements. The test tubes are supported by a sponge pad to prevent the bottom of the tubes from moving randomly during handling. The exposed part of the test tube after it is inserted into the sample tray facilitates subsequent testing operations, thereby achieving the effect of not affecting the normal entry of the sample tray into the analyzer for testing.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0018] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0019] This application discloses a sample tray for a blood analyzer, including a sample tray body 1. A rotating rod 4 is rotatably connected to the top of one end of the inner wall of the sample tray body 1. One end of the rotating rod 4 passes through the outer wall of the sample tray body 1 and is fixed with a knob 3. A winding roller 5 is fixed in the middle of the outer wall of the rotating rod 4. A connecting rope 6 is wound around the outer wall of the winding roller 5. A second hinge seat 8 is fixed to the inner wall of the sample tray body 1 at the end away from the winding roller 5. A first connecting rod 11 is hinged to both ends of the inner wall of the second hinge seat 8. A cross rod 12 is hinged to both ends of the first connecting rod 11. A second connecting rod 13 is hinged to both ends of the cross rod 12 at the ends away from the first connecting rod 11. A first hinge seat 7 is hinged to the opposite end of the two second connecting rods 13. One end of the first hinge seat 7 is fixed to one end of the connecting rope 6. An elastic rope 9 is fixed to the opposite end of the two first connecting rods 11. The other ends of the two elastic ropes 9 are fixed to the inner wall of the sample tray body 1.
[0020] Reference Appendix Figure 1 and 3 The system includes multiple crossbars 12, with the ends of adjacent crossbars 12 hinged together. Two first connecting rods 11, two second connecting rods 13, and multiple crossbars 12 are grouped together, with these groups of crossbars 12 arranged horizontally at equal intervals. Adjacent groups of crossbars 12 are movably connected by first connecting blocks 10, which are rotatably connected to the bottoms of two crossbars 12 on either side. Holes between adjacent crossbars 12 are used to hold blood samples after extraction. The system connects via the first hinge seat 7 and the knob 3. The size of the holes between the cross rods 12 is changed by moving the cross rods 12. When placing blood samples, the size of the holes in the cross rods 12 is adjusted to be larger than the diameter of the blood sample tube, making placement faster. After the sample tray 1 is filled with samples, the first hinge seat 7 is moved to the other end, making the holes in the cross rods 12 smaller. The cross rods 12 clamp the blood sample tube for subsequent analysis by the analyzer. After the analysis is completed, the first hinge seat 7 is moved to the knob 3 end again, and then the blood sample can be poured out of the sample tray 1 directly.
[0021] Reference Appendix Figure 4 The rotating rod 4 is fixed with a ratchet 14 on the outer wall near the knob 3. The sample disc 1 is fixed with a second connecting block 15 and a connecting shaft 19 on the outer wall near the knob 3. The connecting shaft 19 is rotatably connected with a toggle rod 17. By rotating the knob 3, the rotating rod 4 is driven to rotate. The winding roller 5 winds the connecting rope 6 around the outside and pulls the first hinge seat 7 to one end. At this time, the elastic rope 9 is stretched.
[0022] Reference Appendix Figure 4The top of the lever 17 is located above the top of the knob 3. A limit block 18 is fixed to the bottom of the lever 17 near the ratchet 14. The limit block 18 is used in conjunction with the ratchet 14. A spring piece 16 is fixed to the top of the lever 17. The other end of the spring piece 16 is fixed to one side of the second connecting block 15. The limit block 18 is locked inside the ratchet 14, so that the first hinge seat 7 will not return to its original position after movement. When the cross rod 12 is needed to limit the test tube, the lever 17 is pressed with a finger to release the limit block 18 and the ratchet 14. At this time, the elastic rope 9 retracts and the cross rod 12 clamps the test tube.
[0023] Reference Appendix Figure 2 The sample tray 1 has a sponge pad 2 fixed at the bottom of its inner wall. The top of the sample tray 1 and the top of the cross rod 12 are set at the same horizontal plane. The sponge pad 2 supports the test tube and prevents the bottom of the test tube from moving randomly. After the test tube is inserted into the sample tray 1, there is still a part of the outside that is convenient for subsequent testing.
[0024] The workflow of this utility model is as follows: First, when placing the blood sample, adjust the size of the hole in the cross lever 12 to be larger than the diameter of the blood sample tube. Turn the knob 3 to rotate the rotating rod 4, and the winding roller 5 winds the connecting rope 6 around the outside. Pull the first hinge seat 7 to one end. At this time, the elastic rope 9 stretches, and the hole in the cross lever 12 becomes larger. The larger hole makes it easier to place the test tube. The limiting block 18 is locked inside the ratchet 14, so that the first hinge seat 7 will not return to its original position after movement. When it is necessary to limit the test tube with the cross lever 12, press the actuating rod 17 with your finger. Release the limiting block 18 and ratchet 14. At this time, the elastic rope 9 contracts, making the hole of the cross rod 12 smaller. The cross rod 12 clamps the blood sample tube for subsequent analysis. The test tube is supported by the sponge pad 2 to prevent the bottom of the test tube from moving randomly. After the test tube is inserted into the sample tray 1, there is still a part of the outside for subsequent testing. After the test is completed, move the first hinge seat 7 to the knob 3 again to separate the cross rod 12 from the test tube. Then the blood sample can be poured out of the sample tray 1 directly.
[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
