An intraoperative blood cleaning and recovery device and method of use

Abstract

The invention discloses an intra-operative blood cleaning and recovery device and a use method. Firstly, an external separator and an internal separator of the intra-operative blood cleaning and recovery device are connected together, then a gauze for absorbing blood is put in an inner cavity of the internal separator, physiological saline water is added in the inner cavity of the internal separator, a power supply is started, a rotating motor drives the internal separator to rotate, the blood is mixed with the physiological saline water after the blood is separated from the gauze through rotation, and the physiological saline water containing the blood rotates on the top layer of the internal separator under the action of centrifugal force and enters the external separator through a liquid separation hole, so that the gauze can be separated from the blood. The intra-operative blood cleaning and recovery device and the use method disclosed by the invention have the advantages that the structure is simple, the operation is convenient, the blood cleaning and recovery device is formed by connecting the external separator and the internal separator, the blood is effectively separated from the gauze, the blood cell damage is prevented, and the effective recovery efficiency of blood components is improved.

Description

technical field [0001] The patent of the present invention relates to an intraoperative blood cleaning and recovery device and its use method, which belong to the technical field. Background technique [0002] At present, after the gauze is dipped in blood or absorbs blood during the operation, when using the blood recovery machine, it is washed in normal saline or squeezed by hand. During this process, a large number of active components such as blood cells and plasma are mechanically destroyed, resulting in low recovery efficiency. The work efficiency of medical staff is low, so some blood cleaning and recovery devices are not perfect enough. Contents of the invention [0003] The purpose of the present invention is to provide a kind of intraoperative blood cleaning with simple structure, simple and convenient operation, effective separation of blood components and gauze by two separators, prevention and reduction of blood cell destruction, and improvement of effective r...
