Description

Technical Field

[0001] This utility model relates to the field of blood storage technology, specifically a blood storage device for animal blood transfusion. Background Technology

[0002] Giant pandas have a unique blood type system. It has been found that they have specific blood types with red blood cell antigens. Only when the blood types of the donor and recipient are completely matched can hemolytic reactions be avoided. Whole blood or red blood cells can usually be stored for 35 days. Due to the small number of wild and captive giant pandas and the large differences in individual health conditions and body size, it is difficult to form a stable and standardized blood reserve. In medical settings, giant panda blood transfusions generally adopt the "collect and transfuse immediately" mode, which can maximize the freshness of the blood. Before transfusion, the blood bags are usually preheated and shaken to adapt to the biological internal environment.

Furthermore, the inner insulation component includes: a replaceable insulation component and a quick-access component, wherein a plurality of the replaceable insulation components are installed on the vertical slots of the cold storage frame, and a plurality of the quick-access components are distributed at equal intervals within the cold storage frame; Furthermore, the replacement insulation component includes: a sliding cold storage plate, which is slidably connected in the vertical slot, and the cold storage frame, the fixed cold storage plate and the sliding cold storage plate are all filled with cold storage agent; Furthermore, the quick-access component includes: a support frame, a vertical plate, and an insulated horizontal plate. The support frame is slidably connected inside the cold storage frame. The front and rear side walls of the support frame are provided with strip-shaped openings. One end of the vertical plate is slidably connected to the strip-shaped opening. The side wall of the support frame is provided with a rectangular slot. The insulated horizontal plate is fixedly installed at the end of the vertical plate away from the support frame. Furthermore, the refrigeration mechanism includes a refrigeration component and a heat dissipation component, wherein the refrigeration component is installed inside the middle side of the housing, and the heat dissipation component is installed below the refrigeration component; Furthermore, the cooling component includes: a semiconductor cooling chip and a first heat sink, with the cooling ends of the two semiconductor cooling chips fixedly installed on the lower side of the cold storage frame, and the first heat sink fixedly installed on the heating end of the semiconductor cooling chip; Furthermore, the preheating and shaking mechanism includes a driving component and a temperature control component, wherein the driving component is installed inside the lower side of the housing, and the temperature control component is installed at the output end of the driving component; Furthermore, the drive assembly includes: a motor, a rotating block, and a transmission rod.

The left and right sides of the rear part of the housing frame are both inclined surfaces, and a second heat sink is fixedly installed on the inclined surfaces.

[0008] Compared with the prior art, the beneficial effects of this utility model are: 1. By placing the blood bag inside the support frame, the refrigerant inside the cold storage frame, fixed cold storage plate, and sliding cold storage plate maintains the local low-temperature environment through low-temperature absorption and high-temperature release of cold energy, thereby maintaining the low-temperature environment of the blood bag. The insulation frame and insulation cover provide the first layer of insulation for the blood bag, and the insulation horizontal plate and support frame provide the second layer of insulation for the blood bag. When the blood bag inside the box needs to be taken out, first open the insulation cover, then pull out the insulation horizontal plate. The insulation horizontal plate moves upward, causing the vertical plate to move upward. When the vertical plate moves upward to the preset position of the strip opening, it moves upward, causing the support frame to move upward, and the support frame to move upward, causing the blood bag to move upward. At this time, the vertical plate is deflected so that it is located in the rectangular slot position, and the insulation horizontal plate makes way to facilitate the retrieval of the blood bag. The blood bag can be quickly retrieved at this time, avoiding the problem of the blood bag being unable to be grasped because it is located entirely within the support frame. This also facilitates the automatic lifting of the blood bag after opening the insulation horizontal plate, making it easy to quickly retrieve the blood bag. At the same time, the double-opening method allows for the retrieval of the blood bag, preventing the temperature of the adjacent blood bags from being affected when retrieving the blood bag. 2. The motor output shaft of the preheating and shaking mechanism drives the rotating block to rotate. The rotation of the rotating block drives the transmission rod to move, which in turn causes the rotating frame to oscillate periodically. This periodic oscillation of the rotating frame causes the receiving frame to oscillate periodically, resulting in the blood bag oscillating periodically within the receiving frame. The cooling fan blows the heat from the first heat sink onto the second heat sink, which then blows it out of the box. This heats the second heat sink, which in turn heats the waste heat generated by the refrigeration mechanism. The second heat sink then transfers the heat to the receiving frame, ensuring that the receiving shell is always in a preheated state during the refrigeration process. This utilizes the waste heat generated by the refrigeration mechanism and keeps the receiving frame in a preheated state. After the heating plate is powered on, it heats the receiving frame. The temperature of the receiving frame is monitored in real time by a temperature sensor, and the controller controls the heating plate to keep the temperature of the receiving frame within a preset range. The periodic oscillation of the blood bag within the receiving frame, combined with the heating, facilitates rapid blood transfusion. This also allows for pre-processing of the blood bag during short-range transportation of the box, facilitating rapid blood transfusion. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0013] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-10 A blood storage device for animal transfusion includes a housing 1, and further includes: a double insulation mechanism 2, a cooling mechanism 3, a preheating and shaking mechanism 4, and a moving mechanism 5. The upper side of the housing 1 is equipped with the double insulation mechanism 2 for multiple insulation of the blood bags for transfusion. The middle side of the housing 1 is equipped with the cooling mechanism 3 for constant cooling of the double insulation mechanism 2. The lower side of the housing 1 is equipped with the preheating and shaking mechanism 4 for preheating and shaking the blood bags to be used. The lower side of the housing 1 is equipped with the moving mechanism 5 for quickly moving the housing 1.

[0014] like Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the dual insulation mechanism 2 includes an outer insulation component and an inner insulation component. The outer insulation component is installed on the upper side inside the box 1, and multiple inner insulation components are installed on the outer insulation component.

[0015] The outer insulation component includes: an insulation frame 21, a cold storage frame 22, an insulation cover 23, and a fixed cold storage plate 24. The insulation frame 21 is fixedly installed inside the upper side of the housing 1. The cold storage frame 22 is fixedly installed inside the insulation frame 21. Multiple vertical slots 25 are equally spaced on the front and rear side walls inside the cold storage frame 22. The insulation cover 23 is hinged to the upper side of the housing 1. The fixed cold storage plate 24 is fixedly installed on the side of the insulation cover 23 near the housing 1.

[0016] The inner insulation component includes: a replacement insulation component and a quick-access component. Multiple replacement insulation components are installed on the vertical slots 25 of the cold storage frame 22, and multiple quick-access components are distributed at equal intervals within the cold storage frame 22.

[0017] The replacement insulation component includes a sliding cold storage plate 26, which is slidably connected in the vertical slot 25. The cold storage frame 22, the fixed cold storage plate 24 and the sliding cold storage plate 26 are all filled with cold storage agent.

[0018] The quick-access component includes a support frame 27, a vertical plate 28, and an insulated horizontal plate 29. The support frame 27 is slidably connected inside the cold storage frame 22. The front and rear side walls of the support frame 27 are provided with strip-shaped openings 210. One end of the vertical plate 28 is slidably connected to the strip-shaped opening 210. The side wall of the support frame 27 is provided with a rectangular slot 211. The insulated horizontal plate 29 is fixedly installed at the end of the vertical plate 28 away from the support frame 27. The support frame 27 is made of aluminum alloy, which is easy to conduct heat.

[0019] The blood bag is placed inside the support frame 27. The refrigerant inside the cold storage frame 22, the fixed cold storage plate 24, and the sliding cold storage plate 26 maintains a local low-temperature environment by absorbing and storing cold at low temperatures and releasing cold at high temperatures, thus maintaining the low-temperature environment of the blood bag. The insulation frame 21 and the insulation cover 23 provide the first layer of insulation for the blood bag, and the insulation horizontal plate 29 and the support frame 27 provide the second layer of insulation. When the blood bag needs to be taken out of the box 1, first open the insulation cover 23, then pull out the insulation horizontal plate 29. The insulation horizontal plate 29 moves upward, causing the vertical plate 28 to move upward. The vertical plate 28 moves upward to the strip opening 2. When the blood bag is in the preset position 10, the vertical plate 28 moves upward, causing the support frame 27 to move upward. The support frame 27 moves upward, causing the blood bag to move upward. At this time, the vertical plate 28 is deflected, so that the vertical plate 28 is located in the rectangular slot 211. The heat preservation horizontal plate 29 makes way to facilitate the retrieval of the blood bag. The blood bag can be quickly retrieved at this time, avoiding the problem of the blood bag being unable to be grasped because it is located entirely within the support frame 27. This also facilitates the automatic lifting of the blood bag after opening the heat preservation horizontal plate 29, making it easy to quickly retrieve the blood bag. At the same time, the blood bag can be retrieved by opening the lid twice, avoiding affecting the temperature of the adjacent blood bags when retrieving the blood bag.

[0020] Example 2: In some embodiments, such as Figures 1-10In a preferred embodiment of the present invention, the refrigeration mechanism 3 includes a refrigeration component and a heat dissipation component. The refrigeration component is installed inside the middle side of the housing 1, and the heat dissipation component is installed below the refrigeration component.

[0021] like Figure 7 As shown, the cooling component includes a semiconductor cooling chip 31 and a first heat sink 32. The cooling ends of the two semiconductor cooling chips 31 are fixedly installed on the lower side of the cold storage frame 22, and the first heat sink 32 is fixedly installed on the heating end of the semiconductor cooling chip 31.

[0022] The heat dissipation assembly includes a cooling fan 33, and a plurality of cooling fans 33 are fixedly installed on the rear side of the first heat sink 32.

[0023] When the semiconductor cooling chip 31 of the cooling component of the cooling mechanism 3 is powered on, the cooling end cools the cold storage frame 22, and the heating end dissipates heat through the first heat sink 32. At the same time, the cooling fan 33 starts to assist the first heat sink 32 in dissipating heat.

[0024] like Figure 8 , Figure 9 , Figure 10 As shown, the preheating and shaking mechanism 4 includes a driving component and a temperature control component. The driving component is installed inside the lower side of the housing 1, and the temperature control component is installed at the output end of the driving component.

[0025] The drive assembly includes a motor 41, a rotating block 42, and a transmission rod 43. The motor 41 is fixedly installed inside the lower side of the housing 1, the rotating block 42 is fixedly installed on the output shaft of the motor 41, and one end of the transmission rod 43 is rotatably connected to the rotating block 42 via a rotating shaft.

[0026] The constant temperature assembly includes: a rotating frame 44, a housing frame 45, a heating plate 46, a temperature sensor 47, and a side cover 48. The rotating frame 44 is rotatably connected to the lower side of the housing 1 via a rotating shaft. The housing frame 45 is fixedly installed on the upper side of the rotating frame 44. The end of the transmission rod 43 away from the rotating block 42 is rotatably connected to the end of the rotating frame 44 away from the housing frame 45 via a rotating shaft. The heating plate 46 is fixedly installed on the lower side of the housing frame 45. Multiple temperature sensors 47 are fixedly installed on the housing frame 45. The side cover 48 is snapped onto the housing frame 45. The left and right sides of the rear of the housing frame 45 are both inclined surfaces 49. A second heat sink 410 is fixedly installed on the inclined surface 49. The housing frame 45 is made of aluminum alloy, which is easy to conduct heat.

[0027] A lithium battery is installed on the lower side of the inside of the housing 1. A controller is also installed on the lower side of the inside of the housing 1. The semiconductor cooling chip 31, the cooling fan 33, the motor 41, the heating plate 46, and the temperature sensor 47 are all electrically connected to the controller.

[0028] After removing the blood bag, pull the side cover 48 out of the receiving frame 45, place the blood bag inside the receiving frame 45, close the side cover 48, and the output shaft of the motor 41 of the preheating and shaking mechanism 4 rotates, driving the rotating block 42 to rotate. The rotation of the rotating block 42 drives the transmission rod 43 to move, and the movement of the transmission rod 43 drives the rotating frame 44 to swing periodically. The periodic swing of the rotating frame 44 drives the receiving frame 45 to swing periodically, so that the blood bag swings periodically inside the receiving frame 45. The cooling fan 33 blows the heat from the first heat sink 32 onto the second heat sink 410 and then blows it out from the box 1, so that the waste heat generated by the refrigeration mechanism 3 heats the second heat sink 410. The second heat sink 410 transfers the heat to the receiving frame 45, so that the receiving shell is always in a preheated state during the refrigeration process of the refrigeration mechanism 3, which utilizes the waste heat generated by the refrigeration mechanism 3 and keeps the receiving frame 45 in a preheated state.

[0029] After the heating plate 46 is powered on, it heats the receiving frame 45. The temperature of the receiving frame 45 is monitored in real time by the temperature sensor 47. The controller controls the heating plate 46 to keep the temperature of the receiving frame 45 within the preset range. The blood bag is periodically oscillating and heated in the receiving frame 45, which facilitates rapid blood transfusion. It is also beneficial for the blood bag to be pre-treated during the small-range movement and transportation of the box 1, which facilitates rapid blood transfusion.

[0030] Example 3: In some embodiments, such as Figures 1-10 In a preferred embodiment of the present invention, the moving mechanism 5 includes: rollers 51 and telescopic rods 52. The two rollers 51 are rotatably connected to the rear side of the box 1 via a rotating shaft. The fixed ends of the two telescopic rods 52 are fixedly installed on the rear side wall of the box 1, and a crossbar is fixedly installed on the telescopic end of the telescopic rod 52.

[0031] like Figure 1 , Figure 4 As shown, pull out the telescopic rod 52 of the moving mechanism 5, tilt the box 1, and then quickly move the box 1 via the roller 51.

[0032] 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.
