Description

Technical Field

[0001] The present invention relates to the technical field of blood testing, and in particular to a medical device for testing biochemical calibration fluid. Background Art

[0002] The sample tray is one of the core components of the biochemical analyzer, which directly affects the detection efficiency, sample management capabilities and instrument automation level; Currently, sample trays are often tested in batches after preparation, so blood samples are stored in the sample trays for a certain period of time. In order to prevent sample expiration, some sample trays are integrated with a refrigeration chamber to maintain a low-temperature environment for the samples by circulating cooling gas to prevent biological activity degradation. Currently, cooling gas easily escapes from the test tube openings of the sample trays, resulting in unconcentrated cooling of the blood samples in the test tubes. In addition, in order to facilitate the extraction of the sampling needle, the blood samples are in an open test tube state in the sample tray. At this time, the cooling gas will pose a risk of contamination to the samples in the test tubes. In addition, during the operation of the sampling needle, the sample will fall off, which can easily cause contamination of adjacent test tubes. Based on this, a medical device for biochemical calibration fluid testing is proposed. Summary of the Invention

[0019] Example, see Figures 1 to 7 A medical device for biochemical calibration fluid testing includes a biochemical detector for blood testing. The biochemical detector is provided with a blood sample chamber 1 for storing blood. A sample tray 2 is connected to the blood sample chamber 1 through a servo control device. Furthermore, the servo control device includes a rotating gear ring fixedly connected to the outer wall of the sample tray 2. A control motor is provided in the blood sample chamber 1. The output end of the control motor is fixedly connected to a control gear tray meshed with the rotating gear ring. The servo control device is a prior art and will not be described in detail here. The sample tray 2 in the blood sample chamber 1 is controlled to rotate by controlling the motor to realize the one-by-one transportation of multiple blood test tubes on the sample tray 2.

[0020] A storage cavity 3 is provided in the sample tray 2, and a cold collecting inner tray 4 is provided on the inner wall of the storage cavity 3. A cold collecting transport device for low-temperature storage of blood is provided on the cold collecting inner tray 4. Furthermore, the cold collecting transport device includes a cold collecting pipe 12, the end of the cold collecting pipe 12 extends upward through the cold collecting inner tray 4, and is fixed with a pressure air hood 13. An arc-shaped tray 14 for supporting the bottom of the test tube is provided on the outer wall of the cold collecting inner tray 4, and an air return cooling cover 25 is provided on the inner wall of the storage cavity 3. The air return cooling cover 25 is connected to the return cooling pipe 26.

[0021] It should be noted that the cold collection pipe 12 is externally connected to the refrigeration module in the biochemical detector, and air is supplied to the cold collection pipe 12 through the refrigeration module. Under the action of the air pressure hood 13, the delivered cold air will be compressed and transported to the surroundings along the arc disk 14. At this time, the obliquely placed blood test tubes at the arc disk 14 can be efficiently cooled by the cold air. By guiding the wind direction, the blood test tubes can be quickly and effectively cooled.

[0022] The sample tray 2 is detachably provided with a conveyor tray 5, on which a plurality of test tube seats 6 are evenly arranged. The test tube seats 6 are rotatably provided with a steering ball seat 7 for placing the test tubes. The steering ball seat 7 is made of rubber material, and has a large friction force with the placed test tubes, which can ensure the preservation of the placed test tubes. A liquid-cooled regulating motor 8 is provided in the storage chamber 3. The liquid-cooled regulating motor 8 is a prior art and will not be described in detail here. The liquid-cooled regulating motor 8 is connected to a sliding traction plate 9 through a joint-control traction member. Furthermore, the joint-control traction member includes a joint-control traction disc 19 fixedly connected to the output end of the liquid-cooled regulating motor 8. A plurality of joint-control rods 20 are staggeredly arranged on the outer side wall of the joint-control traction disc 19. The end of the joint-control rod 20 is rotatably connected to the sliding traction plate 9 through a traction column 21.

[0023] A support plate 10 for adjusting the angle of the test tube is provided in the storage chamber 3 at the bottom of the test tube holder 6. Both ends of the support plate 10 are provided with linkage parts. Furthermore, the linkage parts include support rods 15 rotatably connected to both sides of the support plate 10. The ends of the support rods 15 are rotatably connected to traction horizontal rods 16. The traction horizontal rods 16 are provided with sliding openings 17. The bottom of the conveying plate (5) is fixedly connected to a limiting slide column 18 adapted to the sliding opening 17. When the inter-control traction disk 19 rotates, it will drive multiple inter-control rods 20 to drive the sliding traction plate 9 to slide horizontally. At this time, the traction horizontal rod 16 connected by the slow-connection spring will be driven to move under the action of the pulling force of the sliding traction plate 9, and the traction horizontal rod 16 located on the inner side will drive the supporting disk 10 to move inward through the supporting rod 15.

[0024] The linkage part located on the inner side is connected to the sliding traction plate 9 through a dynamic slow-moving part. The dynamic slow-moving part includes a sliding groove opened on the sliding traction plate 9. Side sliders 22 are provided on both sides of the traction horizontal rod 16 and are slidably connected to the inner wall of the sliding groove. The sliding groove is connected to the end of the traction horizontal rod 16 through a slow-moving spring.

[0025] The linkage member located on the outside is connected to the magnetic control plate 11, and a magnetic attraction component is provided at one end of the magnetic control plate 11. The magnetic attraction component includes a controllable magnetic attraction plate 23 provided on the inner wall of the blood sample chamber 1. One end of the magnetic control plate 11 is fixedly connected to a permanent magnet block 24 that is magnetically attracted to the controllable magnetic attraction plate 23. A shielding cover is provided on the inner wall of the storage chamber 3 between adjacent permanent magnet blocks 24 to prevent mutual interference between adjacent permanent magnet blocks 24; When the controllable magnetic plate 23 is opened, the magnetic control plate 11 connected to the permanent magnet block 24 will generate an outward pulling force on the supporting plate 10. Under this force, the inner linkage part connected by the dynamic slow-moving part will be pulled, so that the supporting plate 10 connected to the supporting rod 15 will move to its original position for the sampling needle to perform normal sampling, thereby not changing the sampling operation of the existing biochemical detector.

[0026] Furthermore, a friction layer 27 is provided on the upper surface of the steering placement ball seat 7, and the blood sample chamber 1 is hingedly provided with a cover plate 28, and a pressure friction ring 29 is provided on the cover plate 28 to contact the friction layer 27. Under the action of the pressure friction ring 29, after the blood sample tube is placed, the cover plate 28 is closed. After the cover plate 28 is closed, the pressure friction ring 29 on the closed cover plate 28 will contact the friction layer 27 on the steering placement ball seat 7. At this time, when the sample disk 2 rotates and drives the steering placement ball seat 7 to move in a circular manner, the steering placement ball seat 7 without a blood sample tube installed will be driven to rotate under the action of the pressure friction ring 29 during movement, and then the test tube opening opened on the steering placement ball seat 7 will be closed, thereby ensuring that cold air will not escape from the test tube opening, ensuring centralized cooling, and avoiding the occurrence of cold air contamination of the blood sample.

[0027] When testing a biochemical calibration fluid (blood) using a biochemical detector, the present invention places a blood sample tube in the deflection placement ball seat 7 on the sample tray 2. The bottom of the blood sample tube contacts the cold collecting inner tray 4. After all the blood sample tubes are placed, the cover 28 is closed. As the sample tray 2 is driven to transport the blood sample tubes, the pressure friction ring 29 on the cover 28 contacts the friction layer 27 on the deflection placement ball seat 7. The deflection placement ball seat 7 without a blood sample tube placed therein automatically closes during the rotation process, thereby preventing cold air from escaping and contamination of the opening of the blood sample tube. At this time, the synchronous control and liquid cooling adjustment motor 8 drives the connected joint control traction disk 19 to rotate. When the joint control traction disk 19 rotates, it drives multiple joint control rods 20 to drive the sliding traction plate 9 to slide horizontally. At this time, the traction horizontal rod 16 connected by the slow-connection spring will be driven to move under the action of the pulling force of the sliding traction plate 9. The traction horizontal rod 16 located on the inner side will drive the supporting disk 10 to move inward through the supporting rod 15. At this time, the movement of the supporting disk 10 will cause the blood sample tube sleeved therein to be subjected to an inward traction force, thereby generating rotation at the steering placement ball seat 7. After rotation, the blood sample tube is in an inclined state with its opening outward, and the steering placement ball seat 7 will also block and seal the opening of the blood sample tube, thereby avoiding contamination of adjacent blood samples during the extraction process of the sample sampling needle; At this time, the blood sample tube is set at an angle at the bottom. The blood sample in the tube increases the contact area with the inner wall of the tube. At this time, the contact area between the cold air and the blood sample is significantly increased, thereby achieving rapid cooling of the blood sample during storage and realizing the concentrated effect of the cold air. When the blood sample tube moves to the position of the sample sampling needle, the controllable magnetic plate 23 is controlled to open. Under the magnetic attraction of the controllable magnetic plate 23, the permanent magnet block 24 here will be attracted and moved. At this time, the magnetic control plate 11 connected to the permanent magnet block 24 will generate an outward pulling force on the supporting plate 10. Under this force, the inner linkage part connected by the dynamic slow-moving part will be pulled, so that the supporting plate 10 connected to the supporting rod 15 will move to its original position for the sampling needle to perform normal sampling.

[0028] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
