Description

Technical Field

[0001] The present invention provides a blood sample storage device, and particularly relates to the technical field of medical equipment. Background Art

[0002] After the blood sample is taken, it needs to be stored in time to ensure the effectiveness of the components in the blood sample for subsequent testing.

[0003] The utility model with authorization announcement number CN216444044U discloses a blood sample storage device for hematology. The storage device facilitates the removal of blood sample tubes through a sampling port, effectively reducing the risk of contamination; in addition, the protection effect of the blood sample tubes is improved to avoid collisions and damage during movement. At the same time, the utility model with authorization announcement number CN215555189U discloses a leukemia blood sample storage device. The storage device can control the temperature of the blood sample in the storage box by providing a storage box body and a semiconductor refrigeration plate. The fixed cylinder provided in the placement hole can be used to place the blood sample in the fixed cylinder and then move it into the storage box body for temperature control. By providing multiple placement holes, multiple blood samples can be placed one by one, which can avoid a large amount of temperature loss and ensure the normal use of blood.

[0004] The aforementioned "blood sample storage device for hematology" requires manual opening of the sealing plugs one by one during use, followed by manual rotation of the handle, and the cooperation of other components to remove the blood test tubes. This manual operation is relatively inconvenient. At the same time, since the internal refrigeration space cannot be effectively isolated from the external space after the sealing plug is opened, the internal cold air will be lost after the sealing plug is opened, which is not conducive to blood preservation. The aforementioned "leukemia blood sample storage device" is also not convenient to operate during use, and it cannot effectively prevent the loss of cold air when removing the blood test tubes.

[0005] Therefore, the present invention proposes a blood sample storage device to remedy and improve the deficiencies of the prior art. Summary of the Invention

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example 1: Figures 1 to 3 As shown, the blood sample storage device includes a cryogenic box 1, which is hingedly connected to a lid 11. The lid 11 and the cryogenic box 1 are sealed by a buckle, and a sealing ring is provided on the side of the lid 11 close to the cryogenic box 1. After unlocking the buckle, the lid 11 can be opened to facilitate personnel to clean the interior of the cryogenic box 1. When the lid 11 is closed, the sealing ring ensures the sealing of the cryogenic box 1. A refrigeration unit 12 is fixedly installed at the bottom of the cryogenic box 1. A plurality of copper tubes 13 are fixedly connected to the refrigeration unit 12. A plurality of air outlet trays 14 are evenly fixedly connected to the bottom surface of the interior of the cryogenic box 1. Each of the air outlet trays 14 is provided with a plurality of air outlet nozzles for discharging cold air. The plurality of copper tubes 13 are fixedly connected to the corresponding air outlet trays 14.

[0022] The refrigeration unit 12 is controlled by an external control unit. The refrigeration unit 12 is started by the control unit, and then cold air is sent into the low-temperature box 1 through the copper tube 13 and the air outlet nozzle on the air outlet plate 14, thereby providing a refrigerated environment for blood storage.

[0023] As an improvement, Figures 1 to 8As shown, the low-temperature box 1 is provided with an independent access mechanism, which includes fixed boxes 21 symmetrically fixedly connected to both sides of the low-temperature box 1. A plurality of fixed boxes 21 are evenly arranged on both sides of the low-temperature box 1. The low-temperature box 1 is provided with rectangular openings at positions corresponding to the plurality of fixed boxes 21, and is connected to the fixed boxes 21 through the rectangular openings. The tops of the plurality of fixed boxes 21 are respectively provided with circular holes 2101, and the top surface of each fixed box 21 is respectively fixedly provided with a label plate 2102. The label plate 2102 can be used by medical staff to paste or record relevant information of the collected blood.

[0024] The label plate 2102 is located on the side close to the low-temperature box 1. A controller 22 is fixedly installed on the surface of each fixed box 21 on the side away from the low-temperature box 1. Two slot plates 23 are symmetrically fixedly connected to the bottom side of the interior of each fixed box 21. The two slot plates 23 extend into the interior of the low-temperature box 1. A straight slot 231 is opened on the side close to each other of the two slot plates 23. A slot frame 233 is fixedly provided on the side away from the low-temperature box 1. The slot on the slot frame 233 is connected to the straight slot 231. A sliding block 231 is slidably connected in the straight slot 231. 32. A tray 24 is fixedly connected to one side of the sliding block 232 away from the straight groove 231. The tray 24 is used to hold test tubes containing blood oxygen samples. The number of trays 24 can be no less than eight, and four trays 24 are symmetrically distributed inside the low-temperature box 1 as a group. The above-mentioned air outlet plates 14 correspond one-to-one to the trays 24, and the air outlet plates 14 are arranged below the trays 24. That is to say, there is a corresponding air outlet plate 14 below each tray 24 that can deliver cold air, thereby improving the refrigerated storage effect of the blood samples.

[0025] The sliding block 232 is initially positioned within the straight slot 231, near the side of the cryostat 1. The portion where the sliding block 232 slides in contact with the straight slot 231 is a rectangular block, ensuring the stability of the tray 24 as the sliding block 232 slides within the straight slot 231. A horizontal slot 234 is defined on one side of one of the slot plates 23. A movable plate 25 is slidably connected within the horizontal slot 234. The horizontal slot 234 is longer than the straight slot 231. The movable plate 25 has an inclined slot 26 defined on it. The sliding block 232 passes through the inclined slot 26 to contact the straight slot 231 and slide within the inclined slot 26. The portion where the sliding block 232 slides in contact with the inclined slot 26 is cylindrical, ensuring stable sliding movement between the two portions.

[0026] An electromagnet 1 27 is fixedly connected to the bottom of the movable plate 25 on the side close to the sliding block 232, and an electromagnet 2 271 is fixedly connected to the bottom of the side of a slot plate 23 away from the low temperature box 1. The electromagnet 2 271 corresponds to the electromagnet 1 27. The same number of wire wheels 28 as the fixed box 21 are rotatably connected to the bottom surface inside the low temperature box 1. The wire wheels 28 are located on the side close to the tray 24. A clockwork spring 29 is connected to the part where the wire wheels 28 are rotatably connected to the low temperature box 1. One end of the clockwork spring 29 is fixedly connected to the bottom surface of the wire wheel 28, and the other end is fixedly connected to the bottom surface inside the low temperature box 1.

[0027] A pull rope 210 is wound around the reel 28. One end of the pull rope 210 is fixedly connected to the reel 28, and the other end of the pull rope 210 is fixedly connected to the outer surface of the tray 24. An L-shaped plate 211 is fixedly connected to the side of the tray 24 away from the groove plate 23. A blocking plate 212 is slidably provided on the bottom surface of the cold box 1 at a position corresponding to the rectangular opening. Specifically, two strip rods are symmetrically provided at the bottom of the blocking plate 212, and parallel grooves are provided at positions corresponding to the strip rods on the bottom surface of the cold box 1. The strip rods slide in the parallel grooves on the parallel grooves on the bottom surface of the cold box 1. A grooved block 213 is fixedly connected to the blocking plate 212 at a position corresponding to the L-shaped plate 211. The end of the L-shaped plate 211 close to the grooved block 213 is inserted into the grooved block 213.

[0028] Furthermore, if Figure 6 、 Figure 7 As shown, at least four extension bars 241 are evenly fixed on the top of the tray 24. Both the tray 24 and the extension bars 241 are made of rubber, and multiple strip-shaped holes are evenly distributed on the tray 24 and the extension bars 241. The four extension bars 241 work together with the tray 24 to ensure the stability of the blood test tubes, preventing damage to the blood test tubes due to external forces, thereby ensuring the safe storage of blood samples. The strip-shaped holes on the tray 24 and the extension bars 241 ensure that cold air can reach the blood test tubes, preventing the test tubes from being refrigerated.

[0029] Furthermore, if Figure 6 and Figure 9As shown, the independent access mechanism also includes an ejection assembly, which includes a push rod 31 movably inserted into a slot frame 233 on the side away from the second electromagnet 271. The slot frame 233 has a rectangular through-hole through which the push rod 31 can move up and down. A vertical spring 32 is fixedly connected between the push rod 31 and the slot frame 233. A connecting rod 33 is rotatably connected to the top of the push rod 31. A limit rod 35 is fixedly connected to the side of the fixed box 21 near the circular hole 2101. A sealing cover 34 is slidably connected to the limit rod 35. The initial position of the sealing cover 34 corresponds to the circular hole 2101. A sealing sheet is provided on the side of the sealing cover 34 near the circular hole 2101 to ensure the sealing of the sealing cover 34 to the circular hole 2101. The sealing sheet is rotatably connected to the end of the connecting rod 33 away from the push rod 31.

[0030] During use: the medical staff starts the refrigeration unit 12 through the external control unit, so that the interior of the low-temperature box 1 is in a low-temperature space. When the medical staff needs to store the collected patient's blood test tubes, the medical staff uses any controller 22 to energize the electromagnet 1 27 and the electromagnet 2 271. After the two are energized, the magnetic properties are opposite, so that the electromagnet 1 27 drives the movable plate 25 along the trajectory of the horizontal long groove 234, and moves horizontally in the direction close to the electromagnet 2 271, until the electromagnet 1 27 and the electromagnet 2 271 are finally fitted together. In this process, as the movable plate 25 moves horizontally, it will also drive the sliding block 232 to move synchronously along the trajectory of the straight groove 231, and drive the tray 24 to move synchronously. As the tray 24 moves synchronously, it will drive the pulley 28 to rotate through the pull rope 210, and the clockwork spring 29 will gradually deform during the process. As shown in FIG. Figure 7 、 Figure 9 As shown, when electromagnet 1 27 drives the sliding block 232 to the position of the slot frame 233, the sliding block 232 has just slid to its final position in the straight slot 231. At this time, the tray 24 and the extension bar 241 are aligned with the circular hole 2101 and the sealing cover 34, and the flat surface of the sliding block 232 is in contact with the groove surface of the straight slot 231. Since the horizontal slot 234 is longer than the straight slot 231, during the process of electromagnet 1 27 and electromagnet 2 271 being attracted, electromagnet 1 27 also drives the movable plate 25 to slide a distance in the horizontal slot 234. During this process, as the movable plate 25 continues to move, it squeezes the cylindrical portion of the sliding block 232 through the inclined slot 26, thereby forcing the sliding block 232 to move upward along the trajectory of the slot frame 233, thereby driving the tray 24 and the extension bar 241 to move upward synchronously.

[0031] When the movable plate 25 drives the sliding block 232 to move horizontally toward the direction close to the electromagnet 2 271 to the final position in the straight groove 231, it will also drive the blocking plate 212 through the tray 24 and the L-shaped plate 211 to move horizontally along the trajectory parallel to the groove toward the rectangular opening on the low-temperature box 1, and finally make the blocking plate 212 just block the rectangular opening.

[0032] Simultaneously, as the sliding block 232 moves upward, it pushes the ejector pin 31 upward, compressing the vertical spring 32. As the ejector pin 31 moves upward, it drives the connecting rod 33 to rotate, thereby pushing the sealing cover 34 horizontally along the trajectory of the limiting rod 35 toward the cryostat 1. Ultimately, the sealing cover 34 is completely away from the circular hole 2101, exposing the circular hole 2101. Medical personnel can then place the blood test tube downward through the circular hole 2101 into the fixed box 21, ultimately placing the blood test tube on the tray 24 between the extension bars 241. The medical staff then uses the controller 22 to de-energize electromagnet 1 27 and electromagnet 2 271. Following this de-energization, the vertical spring 32's rebound force drives the push rod 31 downward. This pushes the slider 232 downward, forcing the cylindrical portion of the slider 232 to press against the slanted slot 26 again. This in turn causes the movable plate 25 to shift horizontally along the trajectory of the horizontal slot 234, toward the cryostat 1, until the cylindrical portion of the slider 232 slides to its initial position in the slanted slot 26, at which point the slider 232 is also located within the straight slot 231. Subsequently, the rebound force of the spring 29 drives the pulley 28 to rotate in the opposite direction, pulling the tray 24, movable plate 25, and other components horizontally in the opposite direction via the pull rope 210, automatically delivering the blood test tubes into the cryostat 1. This completes the blood test tube storage process. Following these steps, the medical staff can then sequentially place multiple blood test tubes into the cryostat 1.

[0033] Therefore, when medical staff need to store blood test tubes, when the tray 24 moves horizontally to the inside of the fixed box 21, the blocking plate 212 will be automatically sealed at the rectangular opening, thereby isolating the internal space of the low-temperature box 1 from the fixed box 21, thereby preventing the cold air inside the low-temperature box 1 from continuously escaping outward. At the same time, when medical staff place the blood test tubes downward, they do not need to open the box cover 11, but first place each circular hole 2101 test tube into the tray 24 one by one, and then enter the interior of the low-temperature box 1 through the fixed box 21. During the process, no excessive cold air will leak out, thereby ensuring that the interior of the low-temperature box 1 has a good refrigerated storage environment, which is conducive to the refrigerated storage of blood samples.

[0034] In addition, through the cooperation of the controller 22, tray 24, electromagnet 1 27, electromagnet 2 271 and other components, when storing blood test tubes, medical staff automatically move the tray 24 and the extension bar 241 to a position convenient for medical staff to place the blood test tubes, and automatically open the sealing cover 34 originally sealed in the circular hole 2101. After the blood test tubes are placed, the controller 22 can also automatically send the blood test tubes into the low temperature box 1 for refrigerated storage. During the process, medical staff do not need to perform excessive operations, thereby improving the convenience of blood test tube storage.

[0035] When the medical staff needs to take out the blood test tubes inside the low-temperature box 1, the medical staff observes the relevant information on the label plate 2102 and energizes the electromagnet 1 27 and the electromagnet 2 271 through the controller 22, so that the blood test tubes placed in the tray 24 can be automatically moved to the bottom of the circular hole 2101. At the same time, the sealing cover 34 will be automatically opened and the rectangular opening will be automatically sealed to prevent the cold air inside the low-temperature box 1 from continuously leaking out, thereby making it convenient for the medical staff to directly take the required blood test tubes from the circular hole 2101.

[0036] Example 2, as Figure 10 、 Figure 11 As shown, the blood sample storage device also includes a cooperating rotation mechanism disposed on both sides of the cryostat 1. The cooperating rotation mechanism includes a rack 41 fixedly connected to the interior of the fixed box 21. A rotating disk 42 is rotatably connected to the center of the bottom of the tray 24. This rotating disk 42 is made of elastic rubber and can clamp and wrap the bottom of the test tube to ensure the stability of the test tube. A circular plate 45 is fixedly connected to the bottom end of the rotating disk 42 that passes through the tray 24. A pawl 46 is rotatably connected to the side of the circular plate 45 away from the rotating disk 42. A torsion spring 47 is connected to the rotational connection between the pawl 46 and the circular plate 45. One end of the torsion spring 47 is fixedly connected to the circular plate 45 and the other end is fixedly connected to the pawl 46. A gear plate 43 is rotatably connected to the bottom surface of the tray 24. The rack 41 is located in the horizontal motion path of the gear plate 43. Specifically, when the gear plate 43 moves to the position of the rack 41, the two engage with each other. A ratchet ring 44 is fixedly connected to one side of the gear plate 43 close to the circular plate 45 , and the ratchet ring 44 and the pawl 46 are engaged with each other. Specifically, the inner ring surface of the ratchet ring 44 is provided with evenly distributed ratchet teeth, and initially the pawl 46 is engaged with the ratchet teeth.

[0037] During use: When a blood test tube is placed inside the tray 24, the bottom of the blood test tube contacts the upper surface of the rotary disk 42. As the tray 24 moves into the fixed box 21, it also causes the rotary disk 42, circular plate 45, ratchet 46, and gear plate 43 to move synchronously. When the gear plate 43 engages with the rack 41, it will drive the gear plate 43 to rotate clockwise. During this process, the ratchet 46 does not drive the circular plate 45 to rotate. When the blood test tube is placed in the tray 24 and sent into the cold box 1, the rack 41 engages with the gear plate 43, causing the gear plate 43 to rotate counterclockwise. At this time, the gear plate 43 drives the circular plate 45 and the rotary disk 42 to rotate synchronously through the ratchet 46, thereby utilizing the friction between the rotary disk 42 and the bottom of the blood test tube to drive the blood test tube to rotate. Therefore, when the blood test tube is placed in the fixed box 21 and enters the low-temperature box 1, the blood test tube is caused to rotate, which can promote the mixing effect of the blood sample and the blood anticoagulant, reduce the coagulation of the blood sample, and thus help maintain the uniformity of the sample and reduce the impact on subsequent test results.

[0038] When the medical staff needs to take the blood test tube out of the low-temperature box 1, when the blood test tube passes through the interior of the fixed box 21, the ratchet ring 44 and the pawl 46 will not drive the turntable 42 to rotate, that is, the turntable 42 will not rotate before the blood test tube is taken out for testing, thereby avoiding the test tube rotating when taking out and causing the blood sample inside the test tube to shake, and the following subsequent testing effects.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
