Abstract

The invention relates to a dry type plasma thawing instrument, which is characterized in that a water tank (4) and a thawing room (1B) are arranged in a chassis (1), wherein a plurality of layers of plasma thawing bags (6) are arranged in the thawing room at intervals, a water inlet of each plasma thawing bag is connected with a thawing water pump outlet through a thawing pipeline, a water outlet is communicated with the water tank through a thawing pipeline, and water used for thawing is arranged in the water tank; a heater (9) is wrapped outside a heating pipeline (13), the heating pipeline is provided with a heating water pump, and both ends of the heating pipeline are both communicated with the water tank; and an inlet and an outlet of a cooling water pump (11) in a refrigerating device are respectively communicated with the water tank (4). According to the dry type plasma thawing instrument, frozen plasma is packed with plasma thawing bags or plasma thawing membrane bags containing circulating water to be thawed, and the instrument can thaw the frozen plasma bags at a specified thawing water temperature in addition to ensure the whole plasma thawing process to be water proof and totally-enclosed dry type thawing, and is suitable for being used in hospitals, blood supply stations, blood product enterprises, medical research institutions and the like.

Description

technical field [0001] The invention relates to a medical plasma thawing instrument, in particular to a dry plasma thawing instrument. Background technique [0002] Frozen plasma in bags for medical use must be thawed and thawed before use. When thawing and thawing, put the frozen plasma bag in water, and turn it manually to make it thaw gradually. In this way, it is difficult to control the melting temperature and uniformity, and the plasma bag directly contacts with water, which is unhygienic and the melting effect is relatively poor. The applicant once proposed ZL200700058309 plasma melting instrument to solve this problem. This patent adopts the thawing slurry bag, adopts the mode of sealing and water insulation when the frozen plasma bag is thawed, the plasma bag does not directly contact with water, contacts with the frozen plasma bag with the thawing slurry bag. Flowing cold water is installed in the thawing bag, and the thawing bag is in contact with the frozen pl...
