Problems solved by technology
Although the above-mentioned inventions can all realize the infusion method that does not require high-level hanging, they still have common shortcomings, that is, they cannot heat the infusion bag, and cannot provide constant pressure: the elastic force of the spring is proportional to the elastic deformation, and the magnet The magnetic force also changes with the distance between the magnet and the iron plate
During the infusion process, the infusion bag will gradually collapse from the bulging state to flat due to the outflow of liquid. In this process, the elastic force of the spring will gradually weaken, while the magnetic force of the magnet will gradually increase. This is what the above invention cannot provide. The Root Cause of Constant Stress

Embodiment Construction
[0010] Below in conjunction with embodiment contrast appendix figure 1 . For further explanation, the present invention includes a pressurized barrel, an electric heating tube, and a pressure box for placing an infusion bag. The pressurized barrel (1) is movably placed in the pressure box (3). When in use, lift the pressurized barrel (1) first, then place the infusion bag (4) between the pressurized barrel (1) and the pressure box (3), and press the infusion bag ( 4) Applying pressure, since the weight of the pressurized barrel (1) filled with liquid is constant, it can provide constant pressure to the infusion bag (4). In winter, the electric heating tube (2) can be connected to the temperature control circuit. The electric heating tube heats the pressurized barrel (1) filled with liquid, and the pressurized barrel (1) transfers the heat to the medicine in the infusion bag (4). liquid.

The invention relates to a constant-pressure thermal insulation box, in particular relates to a constant-pressure thermal insulation box capable of compressing a flexibly packaged infusion bag and keeping the same warm. The constant-pressure thermal insulation box comprises a compression bucket, an electric heating tube, and a pressure-bearing box, and is characterized in that the electric heating tube is arranged in the compression bucket, the compression bucket is filled with liquid, and the compression bucket is movably placed in the pressure-bearing box. When the constant-pressure thermal insulation box is used, the compression bucket is lifted up at first, and then the infusion bag is placed between the compression bucket and the pressure-bearing box, such that the infusion bag is compressed by the own weight of the compression bucket; since the weight of the compression bucket filled with liquid is invariable, constant pressure can be provided to the infusion bag. In winter, the electric heating tube can be connected with a temperature control circuit, such that the electric heating tube can warm the compression bucket filled with liquid, and then the compression bucket transfers heat to liquid medicine in the infusion bag.
Description
[0001] Technology area [0002] The invention relates to a constant-pressure incubator, in particular to a constant-pressure incubator capable of pressurizing and insulating soft-packed transfusion bags, which belongs to medical equipment. Background technique [0003] Infusion is one of the main means of treating diseases. The traditional infusion method is to hang the infusion bag high on the infusion stand, and use the potential energy of the liquid to infuse. It is inconvenient to move during the infusion, and it is uncomfortable to infuse the cold liquid into the human body in winter. . Chinese patent CN201551664U discloses an infusion method using a spring to pressurize an infusion bag, and Chinese patent CN201275265Y discloses an infusion method using a magnet to pressurize an infusion bag. Although the above-mentioned inventions can all realize the infusion method that does not require high-level hanging, they still have common shortcomings, that is, they cannot heat ...
