Description

一种隔热箱 技术领域  Thermal insulation box
本发明涉及医疗药品保藏领域， 特别是涉及一种隔热箱。 背景技术  The invention relates to the field of medical drug preservation, and in particular to a heat insulation box. Background technique
随着生物工程技术的迅猛发展，不断有针对重大疾病和难以医治 疾病的生物类药物出现。这些药物在外界环境温度过高时， 会加速化 学反应， 微生物容易滋生， 从而破坏药物的结构， 使药物变质而没有 达到良好的药效， 有些变质的药物如果不能及时发现， 会给人体造成 严重的副作用，甚至会造成死亡现象，因此生物类药物在研制、储存、 运输等诸多环节中要处于低温环境中。 对药品的冷藏主要分为有源冷藏和无源冷藏。有源冷藏在冷藏时 需要接通电源， 冷藏条件受到一定限制， 同时不间断的通电也需要费 用， 增加成本。 无缘冷藏是依靠蓄冷剂和隔热材料进行冷藏， 通常是 待冷藏药品周围放有蓄冷剂袋，把待冷藏药品和蓄冷剂袋放入隔热材 料制成的容器中， 达到防止热交换和热传导的效果。现在一般使用的 隔热保温材料采用可发性聚苯乙烯板，但可发性聚苯乙烯板的隔热保 温时间短， 在 48小时后就会不断升温， 达不到对药品冷藏的效果。 发明内容  With the rapid development of bioengineering technology, there are continuing biologic drugs for major diseases and difficult to treat diseases. When the temperature of the external environment is too high, these drugs will accelerate the chemical reaction, and the microorganisms will easily breed, thereby destroying the structure of the drug, causing the drug to deteriorate without achieving good efficacy. Some of the deteriorated drugs will cause serious damage to the human body if they are not found in time. The side effects can even cause death. Therefore, biological drugs should be in a low temperature environment in many aspects such as research, storage and transportation. Refrigeration of medicines is mainly divided into active refrigeration and passive refrigeration. Active refrigerating requires power-on when refrigerating, and the refrigerating conditions are limited, and uninterrupted power-on is also required to increase costs. Cold storage is dependent on cold storage and insulation materials. Usually, a cold storage bag is placed around the medicine to be refrigerated, and the medicine and the cold storage bag to be refrigerated are placed in a container made of heat insulating material to prevent heat exchange and heat conduction. Effect. The commonly used thermal insulation material is made of expandable polystyrene board, but the heat-insulating time of the expandable polystyrene board is short, and it will continue to heat up after 48 hours, failing to achieve the effect of refrigerating the medicine.
