Description

Technical Field

[0001] This application relates to the field of blood sample preservation equipment technology, and in particular to a cryogenic preservation box for animal disease blood samples. Background Technology

[0002] In modern animal husbandry and wildlife conservation, the monitoring of animal diseases is crucial. Accurate detection of animal diseases allows for timely implementation of control measures, preventing the spread of diseases and safeguarding animal health and public health safety. Blood sample testing is one of the important methods for diagnosing animal diseases; by analyzing animal blood samples, it can be determined whether an animal is infected with a specific pathogen.

[0003] Currently, existing blood sample preservation boxes have a significant problem in practical use: they need to be frequently opened and closed to store different blood samples. However, during repeated opening and closing operations, the low-temperature environment inside the preservation box constantly interacts with the external environment. This makes it difficult to maintain the low-temperature environment inside the preservation box within a range suitable for blood sample storage. Blood samples are extremely sensitive to changes in storage temperature. Once frequent temperature fluctuations occur, their biological activity will be severely affected. It is possible that when the blood sample is sent to the laboratory for testing, some of the organisms inside cannot survive or maintain their original state, thus greatly affecting the accuracy of subsequent test results. This situation has brought great trouble to medical testing and research.

[0004] To this end, a cryogenic storage box for animal disease blood samples has been invented that can reduce temperature fluctuations caused by frequent opening and closing of the storage box and ensure that blood samples are kept within a suitable storage temperature range. Utility Model Content

[0005] To reduce temperature fluctuations caused by frequent opening and closing of the storage box and ensure that blood samples are kept within a suitable storage temperature range for subsequent sample testing, this application provides a low-temperature storage box for animal disease blood samples.

[0006] This application provides a cryogenic storage box for animal disease blood samples, which adopts the following technical solution:

[0007] The device includes a housing, wherein a holding slot is provided inside the housing, and a plurality of placement holes for loading blood sample tubes are provided inside the holding slots. A clamping mechanism is provided in each placement hole to hold the sample tubes. A connecting cavity is provided at the bottom of the housing, and the connecting cavity is located at the bottom of the placement holes and can communicate with each placement hole. A cooling mechanism is provided inside the housing to introduce cold air into the connecting cavity. A lid is hinged to the top of the housing to close the housing. When the lid is opened, the cooling mechanism introduces cold air into the placement holes.

[0008] Optionally, the cooling mechanism includes an air inlet chamber located at the bottom of the housing and connected to a holding slot. A sliding plate that can slide up and down is provided inside the air inlet chamber. Several second compression springs are fixedly connected to the bottom of the sliding plate, and the bottoms of the second compression springs are fixed inside the air inlet chamber. A cooling chamber is provided inside the housing, located above the air inlet chamber. The air inlet chamber is connected to the cooling chamber. An ice pack holding tray is provided inside the cooling chamber. An exhaust port is provided at the top of the cooling chamber. An inflatable air bladder is provided at the top of the exhaust port. Several connecting thin pipes that can communicate with a connecting chamber are provided inside the air bladder.

[0009] Optionally, a control mechanism is provided between the cooling chamber and the air intake chamber to allow air to flow unidirectionally into the cooling chamber. The control mechanism includes a fixed cylinder located at the bottom of the cooling chamber. A connecting hole is provided inside the fixed cylinder. A sealing plug is provided inside the fixed cylinder to close the connecting hole. A third compression spring is provided on the sealing plug, and the other end of the third compression spring is fixed inside the fixed cylinder.

[0010] Optionally, the box body is provided with a drive mechanism that can drive the sliding plate to move up and down. After the box cover is fully opened, the box cover flips to the rear side of the box body. At this time, the gravity of the box cover continuously pulls the drive mechanism. The drive mechanism includes a guide roller, which is rotatably connected to the box body. A connecting rope is provided at the bottom of the box cover. The connecting rope contacts the guide roller. A connecting rod is provided at the bottom of the connecting rope. The bottom of the connecting rod is fixedly connected to the sliding plate.

[0011] Optionally, the clamping mechanism is located in the placement hole and corresponds one-to-one with the placement hole, including a slot opened in the placement hole, and a clamping block that can slide relative to or opposite to each other in the slot. Each clamping block has an arc-shaped part that can fit with the sample tube. The opposite ends of the two clamping blocks are respectively provided with a first compression spring, and the other ends of the two first compression springs are fixed in the slot.

[0012] Optionally, an ice pack holding slot is provided in the middle of the box, and a sealing cover that can seal the refrigeration chamber is detachably connected to the rear side of the box.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. When the lid is opened via the drive mechanism, the connecting rope at the bottom of the lid pulls the connecting rod upward. The connecting rod drives the sliding plate to slide upward in the air intake chamber, stretching the second compression spring. At this time, the air in the cooling chamber is compressed and enters the expandable airbag, causing the airbag to expand. Then, as the airbag retracts, the cold air in the cooling chamber enters the connecting chamber through the connecting thin pipe and is released into the placement hole for cooling, so that the placement hole can maintain a certain low temperature environment. This design does not require an additional power source and is simple and convenient to operate.

[0015] 2. The clamping mechanism can stably hold blood sample tubes of different sizes, preventing the sample tubes from shaking or colliding inside the storage box, effectively protecting the integrity of the blood samples. Attached Figure Description

[0023] like Figures 1-5 One embodiment shown includes a box body 1, wherein a holding slot 2 is provided inside the box body 1, and ten placement holes 3 for loading blood sample tubes are provided inside the holding slot 2. A clamping mechanism 4 for clamping the sample tubes is provided in the placement holes 3. A connecting cavity 5 is provided at the bottom of the box body 1, and the connecting cavity 5 is located at the bottom of the placement holes 3 and can communicate with each placement hole 3. A cooling mechanism 6 for introducing cold air into the connecting cavity 5 is provided inside the box body 1. A box cover 7 is hinged to the top of the box body 1 for sealing the box body 1. After the box cover 7 is opened, the cooling mechanism 6 introduces cold air into the placement holes 3.

[0024] In this embodiment, the overall structure of the animal disease blood sample cryopreservation box is mainly composed of a box body 1. The box body 1 has a holding slot 2 inside, and the holding slot 2 has multiple placement holes 3 for loading blood sample tubes. The bottom of the box body 1 has a connecting cavity 5, which is connected to each placement hole 3. The top of the box body 1 is hinged with a box cover 7, which is fixed to the box body 1 by a buckle. The box cover 7 can close the box body 1.

[0025] like Figure 5 In one embodiment shown, the cooling mechanism 6 includes an air inlet chamber 8, which is located at the bottom of the housing 1 and communicates with the holding slot 2. A sliding plate 9 that can slide up and down is slidably connected inside the air inlet chamber 8. Four second compression springs 10 are fixedly connected to the bottom of the sliding plate 9. The bottom of the second compression springs 10 is fixed inside the air inlet chamber 8. A cooling chamber 11 located above the air inlet chamber 8 is opened inside the housing 1. The air inlet chamber 8 communicates with the cooling chamber 11. An ice pack holding tray 12 is fixedly connected inside the cooling chamber 11 for holding ice packs and cooling the cooling chamber 11. An exhaust port 13 is opened at the top of the cooling chamber 11. An inflatable air bag 14 is fixedly connected to the top of the exhaust port 13. Multiple connecting thin pipes 15 that can communicate with the connecting chamber 5 are opened inside the air bag 14.

[0026] In this embodiment, the bottom of the box 1 is provided with an air inlet chamber 8, and the air inlet chamber 8 has a sliding plate 9 that can slide up and down. Several second compression springs 10 are connected to the bottom of the sliding plate 9. The upper side of the air inlet chamber 8 inside the box 1 is a cooling chamber 11. The cooling chamber 11 has an ice pack holding tray 12. The top of the cooling chamber 11 has an exhaust hole 13. The top of the exhaust hole 13 is an inflatable airbag 14. The airbag 14 has multiple connecting thin pipes 15 that are connected to the connecting chamber 5.

[0027] The implementation principle is as follows: When the lid 7 is opened, the connecting rope 23 at the bottom of the lid 7 pulls the connecting rod 24 upward. The connecting rod 24 drives the sliding plate 9 to slide upward in the air intake chamber 8, stretching the second compression spring 10. At this time, the space of the cooling chamber 11 decreases and the air pressure increases. The air in the cooling chamber 11 is compressed into the airbag 14. The gas in the airbag 14 cannot be discharged in time, causing the airbag 14 to expand. As the lid 7 continues to open, the sliding plate 9 continues to rise. When the lid 7 is opened to a certain extent and stops moving, the airbag 14 begins to retract, pressing the cold air in the cooling chamber 11 into the connecting chamber 5 through the connecting thin pipe 15, and then into the placement hole 3 from the connecting chamber 5 to cool the blood sample tube.

[0028] like Figure 5 In one embodiment shown, a control mechanism 16 is provided between the cooling chamber 11 and the air inlet chamber 8, which allows air to flow unidirectionally into the cooling chamber 11. The control mechanism 16 includes a fixed cylinder 17, which is located at the bottom of the cooling chamber 11. A connecting hole 18 is provided inside the fixed cylinder 17. A sealing plug 19 that can close the connecting hole 18 is slidably connected inside the fixed cylinder 17. A third compression spring 20 is fixedly connected to the top of the sealing plug 19, and the other end of the third compression spring 20 is fixed inside the fixed cylinder 17.

[0029] The implementation principle is as follows: Under normal conditions, the third pressure spring 20 pushes the sealing slide 19 to close the connecting hole 18, preventing air in the refrigeration chamber 11 from flowing back into the air intake chamber 8. When the cover 7 is pressed down to close again, the sliding plate 9 moves downward in the air intake chamber 8, compressing the air intake chamber 8 and increasing the air pressure in the air intake chamber 8. At this time, the air pushes the sealing slide 19 to overcome the elastic force of the third pressure spring 20 and open the connecting hole 18, so that air can only flow into the refrigeration chamber 11 from the air intake chamber 8 in one direction, ensuring the one-way flow of cold air and continuously providing a low temperature environment for the placement hole 3.

[0030] like Figure 2In one embodiment shown, a drive mechanism 21 is provided inside the box body 1 to drive the sliding plate 9 to move up and down. After the box cover 7 is fully opened, the box cover 7 flips to the rear side of the box body 1. At this time, the gravity of the box cover 7 continuously pulls the drive mechanism 21. The drive mechanism 21 includes a guide roller 22, which is rotatably connected inside the box body 1. A connecting rope 23 is fixedly connected to the bottom of the box cover 7. The connecting rope 23 contacts the guide roller 22. A connecting rod 24 is fixedly connected to the bottom of the connecting rope 23. The bottom of the connecting rod 24 is fixedly connected to the sliding plate 9.

[0031] Implementation principle: When the lid 7 is opened, it flips to the rear of the box body 1 due to gravity. At this time, the gravity of the lid 7 continuously pulls the connecting rope 23. Under the guidance of the guide roller 22, the connecting rope 23 pulls the connecting rod 24 upward, thereby driving the sliding plate 9 to slide upward in the air intake chamber 8, realizing the start of the cooling mechanism 6. No additional power source is required. It is simple and convenient to operate by utilizing the gravity of the lid 7.

[0032] like Figures 1-5 In one embodiment shown, the clamping mechanism 4 is located in the placement hole 3 and corresponds one-to-one with the placement hole 3. It includes a slot opened in the placement hole 3. A clamping block 25 that can slide relative to or opposite to each other is slidably connected in the slot. Each clamping block 25 has an arc-shaped part that can fit with the sample tube. The opposite ends of the two clamping blocks 25 are respectively fixedly connected to a first compression spring 26. The other ends of the two first compression springs 26 are fixed in the slot.

[0033] Implementation principle: When the blood sample tube is placed into the placement hole 3, the sample tube pushes the two clamping blocks 25 to slide in opposite directions, compressing the first compression spring 26. The elastic force of the first compression spring 26 makes the clamping blocks 25 fit tightly against the outer wall of the sample tube, thereby adapting to blood sample tubes of different sizes, preventing the sample tube from shaking or colliding in the storage box, and effectively protecting the integrity of the blood sample.

[0034] like Figures 1-5 In one embodiment, an ice pack storage slot 27 is provided in the middle of the housing 1. A sealing cover 28, which can seal the refrigeration chamber 11, is detachably connected to the rear side of the housing 1. The ice pack storage slot 27 is used to store additional ice packs, increasing the cold source reserve. When it is necessary to replace the ice packs in the refrigeration chamber 11, the sealing cover 28 is opened, and the ice pack storage tray 12 can be easily removed for replacement, ensuring that the storage box can continuously provide a stable low-temperature environment.

[0035] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
