Description

Technical Field

[0001] The utility model relates to the technical field of blood refrigerators, in particular to a cold storage shelf device for a blood refrigerator. Background Art

[0002] The blood refrigerator is a medical refrigerator in the medical industry. Fresh blood has strict temperature fluctuation range requirements for the refrigerator, which generally fluctuates within the range of 2-6°C and has specific temperature control and humidity conditions to ensure the preservation quality and safety of blood and samples.

[0003] Blood products are stored in bags, which means that the blood bags are sorted and put into blood boxes in an orderly manner, so that blood products can be stored and inventoried conveniently. Blood boxes often use air-cooled refrigeration to evenly expand the cold air around the blood bags, and achieve a refrigeration method to cool the blood bags through changes in air cooling.

[0004] The traditional air duct evenly transports the cold air into the box, and the air is returned through the top fan to form an air circulation in the box; the cold air is evenly distributed in the box. When the user opens the door to use it, the internal refrigeration cycle stops, and the cold air will flow out with the door. The traditional blood box is large in size. When the user takes out the blood box, the cold air around the entire blood box will also be taken out with the user's action, causing the loss of cold air. When the blood box is put back in, the local temperature difference is large. After the user finishes using it, the temperature difference inside the blood refrigerator deviates from the set temperature, and the refrigeration is started again to make up for the lost cold air. This is not conducive to reducing the power consumption of the blood refrigerator and does not meet the low energy consumption standard of the product. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 and 2 The utility model provides a blood refrigerator cold storage shelf device, comprising:

[0030] The air duct back plate 300 is provided with an air inlet 301;

[0031] The base 200 is inserted on the air duct back plate 300, and the end portion is connected to the air inlet 301. The base 200 has an air duct K connected to the air inlet 301; and,

[0032] The blood frame 100 is disposed on the base 200 , and the bottom thereof is connected to the air duct K.

[0033] In the utility model, cold air is directly transported to the air duct K through the air inlet 301 of the air duct back plate 300, and the cold air is transmitted to the blood frame 100 through the air duct K, and the cold air is directly transported to the vicinity of the blood bag, thereby reducing the loss of cold air, maintaining the temperature of the blood bag, and improving the refrigeration effect.

[0034] In actual use, the device is placed in a refrigerator, and the air duct back plate 300 and the refrigerator body form a cold air channel. Cold air is sent into the refrigerator through the refrigeration equipment, so that the blood frame 100 maintains a certain temperature to ensure that the blood bag is not damaged.

[0035] In one embodiment, see Figure 3 and Figure 4 The base 200 includes a bottom plate 201 and a cover plate 202. The bottom plate 201 and the cover plate 202 are combined to form an air duct K. The connecting end of the air duct K and the air inlet 301 is open, and the other end is sealed.

[0036] In this embodiment, the cold air enters the air duct K from the air inlet 301 of the air duct back plate 300, and flows through the air duct K to the bottom of the blood frame 100, and finally the cold air flows into the blood bag in the blood frame 100.

[0037] In one embodiment, see Figure 3 and Figure 4 At least one air guide plate 203 facing the blood frame 100 is disposed on the cover plate 202 , the bottom of the air guide plate 203 is connected to the air duct K, and air guide ports 2031 are evenly disposed on both sides of the air guide plate 203 .

[0038] In one embodiment, see Figure 4 and Figure 5 A baffle plate 101 corresponding to the air guide plate 203 is provided at the bottom of the blood frame 100 . The baffle plate 101 is inwardly convex and fits with the air guide plate 203 . Ventilation holes 102 are evenly opened on both sides of the baffle plate 101 .

[0039] The blood bags in the blood frame 100 do not overlap each other due to the baffle plate 101 of the blood frame 100. After the cold air in the air duct K is transmitted to the blood bags, it forms an air circulation in the box upward through the gap. The space at the top of the blood frame 100 is provided with cold air by the air inlet 302, providing 360° cold air without dead angles to the blood bags, thereby efficiently maintaining the temperature control of the blood bags.

[0040] In one embodiment, see Figure 4 The two sides of the air guide plate 203 and the baffle plate 101 are both inclined structures. In this embodiment, when the blood frame 100 is placed on the base 200, the inclined structure has a certain guiding effect, which can improve the accuracy of the blood frame 100 when placed.

[0041] In one embodiment, see Figure 3 The bottom plate 201 is provided with an air guide strip 204 corresponding to the air guide plate 203 , and the air guide strip 204 is convex toward the air duct K. This embodiment is arranged in this way, not only can the cold air be guided to the air guide plate 203 , but also can enhance the strength of the base 200 .

[0042] In one embodiment, the air guiding strip 204 is configured with a 30° chamfered structure.

[0043] In one embodiment, see Figure 2 The base 200 is slidably disposed on the guide rail 400, and the guide rail 400 is fixedly connected to the air duct back plate 300. This embodiment is arranged so that the user can take out the blood frame 100 more conveniently and quickly.

[0044] In one embodiment, see Figure 2The air duct back plate 300 is provided with an air inlet 302, which is flush with the frame opening of the blood frame 100. In this embodiment, the cold air delivered to the blood frame 100 is not only blown by the air duct K at the bottom, but also blown to the frame opening of the blood frame 100 through the air inlet 302, thereby improving the refrigeration effect and maintaining the temperature of the blood bag in the blood frame 100.

[0045] In one embodiment, see Figure 3 The end of the base 200 away from the air duct back plate 300 is provided with a buckle 205. This embodiment is arranged so that when the blood frame 100 is taken out, the staff can easily pull the base 200 out along the guide rail 400 through the buckle 205, and the operation is convenient and efficient.

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.
