Description

Technical Field

[0001] The present invention relates to medical supplies, specifically to a portable blood transport box. Background Art

[0002] According to the "Simple Blood Transport Box" disclosed in the utility model (Application No.: CN201220020003.8), it includes a box body, a box cover is provided on the upper part of the box body, a partition shelf and an inner liner are provided on the inner surface of the box body, the inner liner is placed on the partition shelf, round holes are evenly distributed on the four walls and the bottom surface of the inner liner, there is a certain gap between the inner liner and the inner surface of the box body, a partition layer is arranged inside the inner liner, a lock catch is provided between the box cover and the box body, a handle for easy carrying is installed on the box cover, ice bags are arranged between the inner surface of the box body and the inner liner layer, and the box body and the inner liner are made of polyester plastic. Compared with the prior art, the present invention has a simple structure, is light in weight, is convenient to use, and is suitable for various modes of transportation.

[0003] However, in specific implementation, the entire box body needs to be carried each time. After being filled with blood bags, it is relatively heavy, and the blood collection process is extremely inconvenient. At the same time, when it is necessary to collect blood at two places simultaneously, two blood transport boxes need to be prepared.

[0004] According to the "Simple Standard Blood Transport Box" disclosed in the utility model (Application No.: 200620011334.X), the box body and the box cover are made of expanded polystyrene; multiple through vertical grooves are respectively opened on the inner walls erected on both sides of the box body; plastic film bags filled with ice are placed above each blood bag in the box body; a rectangular outer box made of double corrugated paper is sleeved on the outer periphery of the box body and the box cover. When transporting whole blood or red blood cell suspension, the plastic film bags filled with wet ice can maintain low temperature for 48 hours; when transporting plasma, the plastic film bags filled with dry ice can maintain low temperature for 24 hours. It can be carried on various transportation tools for large - batch long - distance blood transportation without recycling. It solves the problems of the heavy and costly electric refrigerated blood transport box that needs to be recycled; the short low - temperature maintenance time after power failure; poor shock resistance; and it is not suitable for large - batch transportation of blood or blood products on various vehicles.

[0005] However, in specific implementation, during the process of transporting blood, it is not always transported by transportation tools, and people also need to carry the box body. However, the box body is extremely inconvenient to carry during the transportation process. Therefore, we make improvements and propose a portable blood transport box. Summary of the Invention

Magnet sheets 113 are provided at both ends of the transparent film 112. The two magnet sheets 113 are magnetically connected to reduce the leakage of cold air.

[0041] When working, first you need to carry the blood transport box to the blood collection site. During the carrying process, you can choose to use the shoulder strap 4 to carry the blood transport box or use the dragging structure 8 to drag the blood transport box. When dragging the blood transport box, pull out the inner rod in the telescopic pull rod 81. The telescopic pull rod 81 is similar to the luggage case pull rod structure. The inner rod is a steel structure. The inner rod drives the magnet block 82 to move upward. The magnet block 82 pulls the steel wire 833 to drive the clamping block 835 to move. The clamping block 835 no longer blocks the clamping slot on the sleeve 842. The second spring 844 pops open to extend the roller 841, and the inner rod continues to move upward. The magnet block 82 falls off the inner rod, and then pull the telescopic pull rod 81 to drag the blood transport box. When using the shoulder strap 4 to carry the blood transfusion box, The shoulder strap 4 pulls the connecting plate 85, and the connecting plate 85 drives the sleeve 842 to move up, the roller 841 is retracted, and the block 835 is re-inserted into the slot, so that when not in use, it will not be unstable due to the existence of the roller 841. When walking with the carrying handle 3, the box body 1 will move up and down with the person's steps. At this time, the piston 132 moves in the compression cylinder 131 to compress the gas in the compression cylinder 131, so that the compressed gas is input into the condenser 14, and the compressor 15 is assisted to work, saving energy. When only a small amount of blood needs to be transported over a short distance, a small amount of blood bag can be placed in the tool grid 5, and then the tool grid 5 and the connector 6 are removed. When the connector 6 is removed, Turn the pull ring 67 to make the limiting block 66 correspond to the gap between the arc plates 643, then pull the pull ring 67, and then pull the end plate 61 to extract the mounting structure 64, then fold the tool grid 5 through the hinge to form a box body, and then rotate the end plate 61 at one end of the four connecting members 6 through the rotating shaft 68 to make the directions of the mounting structures 64 at both ends of the connecting members 6 the same, and then connect the two tool grids 5 through the mounting grooves on both sides of the tool grid 5. During the installation process, first insert the mounting structure 64 into the mounting groove, and then push the insertion rod 65 in the direction of the mounting groove. The insertion rod 65 will open the arc plate 643 and the anti-slip oblique block 645. At this time, the limiting block 66 slides from the gap to the anti-slip The end of the inclined block 645 is moved to allow the mounting structure 64 to be stuck in the mounting groove, and then the pull ring 67 is rotated, and the anti-slip inclined block 645 blocks the limiting block 66 to prevent the insertion rod 65 from falling out, thereby preventing the box body formed by the two tool grids 5 from being separated, and then the remaining two connecting parts 6 are installed at the front end of the box body to form a handle, and the end plate 61 is pulled, and the mounting structure 64 slides in the opening 62 and is partially pulled out, so that it is convenient to hold the handle, and when the blood bag needs to be taken out, the magnet sheet 113 is pinched and moved, and the transparent film 112 is moved by the rotating rod 111, so that the magnet sheet 113 is located above the blood bag that needs to be taken out, and then the two magnet sheets 113 are separated, and the blood bag is taken out, thereby reducing the leakage of cold air and saving energy.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
