Water-free dry type plasma heating unfreezing instrument

Abstract

The invention provides a water-free dry type plasma heating unfreezing instrument. The water-free dry type plasma heating unfreezing instrument is characterized by comprising an upper cover (1), a lower box body (2), an unfreezing tank (4), a swinging mechanism (5) and a buffering mechanism (6), wherein the upper cover (1) is connected with the lower box body (2) through parallel connecting rods (10), the swinging mechanism (5) is divided into an upper moving part and a lower moving part, and the upper moving part and the lower moving part are mounted in the upper cover (1) and the lower box body (2), respectively; the upper moving part and the lower moving part are connected with each other through connecting plates (11), so that the synchronous movement is realized; the upper half unfreezing tank body and the lower half unfreezing tank body (4) are respectively mounted on corresponding upper and lower swinging plates (8) and are driven by the swinging mechanism (5) to do reciprocating motion; the lower moving part of the swinging mechanism (5) is mounted on a supporting plate (9), the supporting plate (9) is supported by the buffering mechanism (6), and the buffering mechanism (6) is mounted in the lower box body (2); various electrical devices are mounted below the supporting plate (9). The water-free dry type plasma heating unfreezing instrument is simple in structure, rapid and stable in heating and good in unfreezing effect.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood thawing device which can replace the traditional water bath to heat and thaw plasma, and heat the frozen plasma to 37°C for use in operations. Specifically, it is an anhydrous dry plasma heating and thawing apparatus that can be used in an operating room. Background technique [0002] Studies have shown that thawing and warming the blood temperature to 32 ℃ ~ 35 ℃, applied to clinical rescue and treatment of post-traumatic hypovolemic shock, can reduce the occurrence of chills and hypothermia in patients with post-traumatic hypovolemic shock after transfusion of cold blood rate, which is beneficial to improve microcirculation. [0003] Plasma thawing has always been a concern of major hospitals. Plasma is a special precious resource, and it is necessary to carefully search and study all the reasons and countermeasures that cause plasma to be scrapped. At present, plasma is mostly mel...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the existing water-bath blood thawing equipment has a slow thawing speed and is not suitable for use in the operating room, while the electric heating thawing device has a complicated structure, high cost, poor solution effect, and easily causes the quality of blood products to be damaged. Design an anhydrous dry plasma heating and thawing apparatus with electric heating, which can be used in the operating room, the thawing temperature is adjustable, and the thawing process is uniform and consistent.
